Abstract Background Human exposure to micro- and nanoplastic particles (MNPs) is inevitable but human health risk assessment remains challenging for several reasons. MNPs are complex mixtures of particles derived from different polymer types, which may contain plenty of additives and/or contaminants. MNPs cover broad size distributions and often have irregular shapes and morphologies. Moreover, several of their properties change over time due to aging/ weathering. Case-by-case assessment of each MNP type does not seem feasible, more straightforward methodologies are needed. However, conceptual approaches for human health risk assessment are rare, reliable methods for exposure and hazard assessment are largely missing, and meaningful data is scarce. Methods Here we reviewed the state-of-the-art concerning risk assessment of chemicals with a specific focus on polymers as well as on (nano-)particles and fibres. For this purpose, we broadly screened relevant knowledge including guidance documents, standards, scientific publications, publicly available reports. We identified several suitable concepts such as: (i) polymers of low concern (PLC), (ii) poorly soluble low toxicity particles (PSLT) and (iii) fibre pathogenicity paradigm (FPP). We also aimed to identify promising methods, which may serve as a reasonable starting point for a test strategy. Results and conclusion Here, we propose a state-of-the-art modular risk assessment framework for MNPs, focusing primarily on inhalation as a key exposure route for humans that combines several integrated approaches to testing and assessment (IATAs). The framework starts with basic physicochemical characterisation (step 1), followed by assessing the potential for inhalative exposure (step 2) and includes several modules for toxicological assessment (step 3). We provide guidance on how to apply the framework and suggest suitable methods for characterization of physicochemical properties, exposure and hazard assessment. We put special emphasis on new approach methodologies (NAMs) and included grouping, where adequate. The framework has been improved in several iterative cycles by taking into account expert feedback and is currently being tested in several case studies. Overall, it can be regarded as an important step forward to tackle human health risk assessment.

Abstract This study examined the levels of 210Po and the annual effective dose in edible crustaceans from the Santa Barbara River, Nembe. The crustaceans analyzed included Crab (Cardisoma crassum), Prawn (Macrobrachium rosenbergii), Shrimp (Penaeus notalis), and Crayfish (Decapoda reptania). The concentration of 210Po in the crustaceans was measured using an alpha spectrometric procedure, with 209Po tracer used as a yield monitor after acidified HNO3 digestion. The results indicated trace amounts of 210Po in the different crustaceans, with a concentration of 24.17 Bq kg−1 fresh weight in Crab, 0.01 Bq kg−1 fresh weight in Prawn, 50.89 Bq kg−1 fresh weight in Shrimp, and 40.71 Bq kg−1 fresh weight in Crayfish. The doses of 210Po concentration from the crustaceans were calculated using ingestion dose coefficients of 1.2 μSv Bq−1 for adults, as provided by the regulatory framework that protects humans from exposure to ionizing radiation. The calculated annual effective doses suggested low levels of exposure to crustacean consumers, with values below the recommended limit of 1000 μSv y−1 set by the ICRP for effective dose. The crustaceans with the highest annual committed effective doses of 210Po were Penaeus notalis and Decapoda reptania. However, even small amounts of 210Po in crustaceans can lead to contamination that may be harmful to human health.

Abstract This study investigated residual levels of carbosulfan and its metabolites in date palm fruit in the UAE using HPLC-MS/MS and QuEChERS method. The method demonstrated excellent linearity (R2 > 0.998), low LOD (0.001–0.04 μg/kg) and LOQ (0.003-0.1 μg/kg), and high recoveries (92-103%) with low RSD values (1–9%). The matrix effect was negligible (-16.43–17.09%), and uncertainty measurements did not exceed the 50% limit. Carbosulfan was present in all samples, exceeding its MRL in 46% of the samples. Carbofuran and 3-hydroxycarbofuran exceeded their MRL in 4.87% and 40% of the samples, respectively, while 3-ketocarbofuran levels were below the MRL. Dibutylamine was found in 82% of the samples, with an average concentration of 9.01 µg/kg. The health risk assessment for children and adults showed that all HQ values were below the safety limit of 1.0, indicating that date consumption poses no adverse health risks for either adults or children.

Abstract Background The targeted application of cutting-edge high-throughput molecular data technologies provides an enormous opportunity to address key health, economic and environmental issues in the tropics within the One Health framework. The Earth’s tropical regions are projected to contain > 50% of the world’s population by 2050 coupled with 80% of its biodiversity however these regions are relatively less developed economically, with agricultural productivity substantially lower than temperate zones, a large percentage of its population having limited health care options and much of its biodiversity understudied and undescribed. The generation of high-throughput molecular data and bespoke bioinformatics capability to address these unique challenges offers an enormous opportunity for people living in the tropics. Main In this review we discuss in depth solutions to challenges to populations living in tropical zones across three critical One Health areas: human health, biodiversity and food production. This review will examine how some of the challenges in the tropics can be addressed through the targeted application of advanced omics and bioinformatics and will discuss how local populations can embrace these technologies through strategic outreach and education ensuring the benefits of the One Health approach is fully realised through local engagement. Conclusion Within the context of the One Health framework, we will demonstrate how genomic technologies can be utilised to improve the overall quality of life for half the world’s population.

Abstract The atmosphere’s fine articulate Matter (PM2.5) poses various health-related risks. Even though multiple efforts have been made to lower the emissions of these substances, the mortality rate is continuously increasing, requiring immediate inclination of the scientific community towards the design and development of advanced predictive models. Conventional statistical approaches have become dormant due to their limitations in capturing the innate relationships between the pollutants, particularly for predicting PM2.5 concentrations. In contrast, machine and deep learning techniques have shown great potential for forecasting air quality, providing more accuracy than its predecessor techniques. The present study investigates the utilization of hybrid approaches by integrating machine learning models with deep learning models to improve the prediction capabilities of PM2.5 concentration. It uses datasets from the World Air Quality Index (WAQI) and the State of Global Air (SOGA) to analyze the performance of the models on both the daily and annual data, respectively. This ensures the model’s effectiveness on a diversified dataset. The present study implements Random Forest (RF), Polynomial Regression (PR), XGBoost, and Extra Tree Regressor (ETR) coupled with Fully Connected Neural Network (FCNN), Long Short-Term Memory (LSTM), and Bi-directional LSTM (Bi-LSTM) for obtaining optimized results. Finally, after a thorough investigation, the hybrid PR model coupled with FCNN (PR-FCNN) is found to be the best model with improved R-squared (R2) values, portraying its potential for predicting PM2.5 concentration accurately. Based on the experimentation, the preset study recommends implementing hybrid approaches, offering better predictive accuracy in forecasting air pollutants, especially PM2.5.

Abstract The aim of this work is the prediction of heat-related mortality for Germany under future, i.e. hotter, climate conditions. The prediction is made based on 2m temperature data from climate storyline simulations using machine learning techniques. We use an echo state network for linking the outputs of storyline climate simulations to the target data. The target data are all-cause mortality rates of Germany for all ages. The network is trained with present day climate model outputs. Model outputs of future, i.e. 2K and 4K warmer, storylines are used to predict mortality rates under such climatic conditions. We find that we can train an echo state network with recent temperature data and mortality and make plausible predictions about expected developments of mortality in Germany based on future climate storylines. The trained network can successfully predict mortality rates for future climate conditions. We find increased mortality during the summer months which is attributed to the presence of more severe heat waves. The mortality decrease found during winter can be explained milder winters leading to fewer deaths caused by respiratory diseases. However, mortality in winter is largely influenced by other factors such as influenza waves or vaccination rate and explainability due to temperature is limited.

A healthy lifestyle encourages people to regularly eat more fruits and nuts, including nutritious snack bars, which provide excellent nutritional and energy value and are exceptional convenience foods with the necessary content of macro- and microelements, dietary fibre and biologically active compounds. The article analyses and proves the usefulness of fruits and nuts, which have a positive impact on human health in snack bars. The consumption of nuts demonstrates a positive effect on health, preventing and/or creating a therapeutic effect on a person by reducing some risk factors associated with chronic diseases. The simulation, which reflects the structure of the population's diet, when all snacks between meals, with the exception of drinks, were replaced by nuts, records a significant decrease in added sugar (-17.8 %), solid fats (-21.0 %), saturated fat (-6.6 %) and sodium (-12.3 %), and an increase in monounsaturated (+35.4 %) and polyunsaturated fats (+42.0 %), vegetable omega-3 fatty acids (+53.1 %), dietary fibre (+11.1 %), magnesium (+29.9 %) and a slight increase in potassium (+1.5 %). The available scientific evidence shows that nut consumption (15 to 30 g per week for 3 to 16 weeks) does not provide additional health benefits for children aged 8 to 18 years, but replacing high-calorie, low-nutrient snacks with nuts can help to promote healthy dietary habits as children grow into adults. A survey of 188 respondents (39.3 % male, 60.7 % female) was conducted to investigate the attitudes of Ukrainian youth towards nut consumption and preferences for snack bar flavours. While protein bars can be considered a speciality food for consumers seeking to increase muscle mass, snack bars based on nuts and dried fruits are seen as snacks with an overall positive impact on the body. When eating, a person has a certain sequence of chemosensory sensations that influence the aesthetic pleasure of eating certain dishes, and the taste preferences of respondents show that the most desirable aroma and taste is chocolate (39.3 %), followed by hazelnut (32.8 %) and strawberry (13.1 %). The least desirable flavours for consumers are blueberry (2.6 %), cereal (2.0 %) and banana (2.0 %). In addition to attention to the vitamin content (44.3 %), respondents are interested in the absence of chemical additives (27.9 %) and sugar (16.4 %) in snack bars. Despite the scientifically proven positive effects of antioxidants and dietary fibre on the human body, only 1.6 % of respondents consider their presence to be a determining factor in choosing a food product. Based on the study conducted by the authors, it was found that using a mixture of nuts and dried fruit for snacking creates a balance between monounsaturated and polyunsaturated fatty acids, provides the body with essential vitamins and is desirable for consumption. Snack bars containing nuts and dried fruits are organoleptically the most desirable for consumers and may be useful in preventing a number of diseases. This study can be used to make managerial decisions in the production of healthy food products.

Abstract Background Plastics are the most flexible products developed with a wide range of applications. They have been incorporated into almost every aspect of daily life due to their strength and low weight. However, widespread use and inadequate waste management have resulted in the accumulation of tiny plastic particles throughout the environment. Main text Microplastics are found in oceans, rivers, sediments, sewers, soil, and agricultural products, even in table salts. Human beings are affected by microplastics through food ingestion and inhalation. Incorporated microplastics may accrue within the body and affect gastrointestinal, immune, endocrine, brain, and respiratory systems. It also interferes with the functions of major organs and causes chromosomal abnormalities. Conclusion Addressing the issue of micro and nanoplastics requires interdisciplinary research, sustainable solutions, and improved waste management systems. The main focus of this review is to cover the harmful effects and impact of microplastics on human health and stress the need for combating strategies.

Many people have associated e-cigarettes with adjectives such as trendy and cool, and regarded vaping as “a safer alternative to cigarette smoking”. Compared with the conventional cigarettes, the public is less familiar with the dangers of e-cigarettes. E-cigarettes produce an aerosol by heating the e-liquid (usually comprising nicotine, flavorings, propylene glycol, vegetable glycerin, and other additives). Harmful substances are generated during the vaporization, such as formaldehyde. Cellular damages and DNA hypermethylation are also found to be associated with vaping. We reviewed the clinical neoplastic cases of patients with vaping history (three oral squamous cell carcinomas, one conjunctival squamous intraepithelial neoplasia, and one thoracic NUT-midline carcinoma). These patients tend to be younger than the average cancer patients. Although the exact relations between the cellular damages or DNA hypermethylation and vaping still need further investigations, we should be very careful about the dangers of using e-cigarettes as aids for cigarette smoking cessation.

Abstract Sphingolipids (SLs) are a class of lipids that are essential components of cell membranes. The main SLs and the metabolites include sphingomyelin, ceramide, and glycosphingolipids. They serve as signaling molecules and can regulate various cellular processes including proliferation, migration, senescence, and apoptosis that are essential for human health. SLs from marine organisms exhibit special structures and diverse physiological functions due to the extreme environment, which have attracted ever‐increasing attention recently. In this review, the contents and structures of SLs from marine sources, analytical methods, their metabolic pathways, as well as the physiological functions, especially the ability for the prevention and/or treatment of various diseases, including immunity, metabolic syndrome, neuroinflammatory, neurodegenerative diseases, and cancer, were discussed.

Currently, information on the toxicity profile of the majority of the identified e‐waste chemicals, while extensive and growing, is admittedly fragmentary, particularly at the cellular and molecular levels. Furthermore, the toxicity of the chemical mixtures likely to be encountered by humans during and after informal e‐waste recycling, as well as their underlying mechanisms of action, is largely unknown. This review paper summarizes state‐of‐the‐art knowledge of the potential underlying toxicity mechanisms associated with e‐waste exposures, with a focus on toxic responses connected to specific organs, organ systems, and overall effects on the organism. To overcome the complexities associated with assessing the possible adverse outcomes from exposure to chemicals, a growing number of new approach methodologies have emerged in recent years, with the long‐term objective of providing a human‐based and animal‐free system that is scientifically superior to animal testing, more effective, and acceptable. This encompasses a variety of techniques, typically regarded as alternative approaches for determining chemical‐induced toxicities and holds greater promise for a better understanding of key events in the metabolic pathways that mediate known adverse health outcomes in e‐waste exposure scenarios. This is crucial to establishing accurate scientific knowledge on mixed e‐waste chemical exposures in shorter time frames and with greater efficacy, as well as supporting the need for safe management of hazardous chemicals. The present review paper discusses important gaps in knowledge and shows promising directions for mechanistically anchored effect‐based monitoring strategies that will contribute to the advancement of the methods currently used in characterizing and monitoring e‐waste‐impacted ecosystems.

Abstract Background The Mediterranean diet (MD), globally recognized for its sustainability and health benefits, traditionally emphasizes the consumption of plant-based foods in raw or minimally processed forms. However, shifting lifestyles, even in Mediterranean regions, have led to an increasing consumption of ultra-processed foods (UPF). Epidemiological evidence suggests that UPF consumption may be detrimental to human health, but there is only one clinical trial on this topic which is largely debated in the scientific community. This study aims to investigate the impact of the inclusion of UPF within a Mediterranean-based dietary pattern on cardiometabolic markers, gut microbiota, and other markers of human and planet health. Methods Fifty clinically healthy individuals showing overweight and presenting a low-to-moderate cardiovascular risk profile will be recruited for a 7-month randomized, open, cross-over dietary trial. Eligible participants will be randomly assigned to a 3-month high-UPF MD (intervention group) or a low-UPF MD (control group), with a 1-month wash-out period. Both intervention diets will have identical food group compositions, with the intervention group consuming 5 servings/day of selected UPF items, and the control group consuming raw/minimally processed items from the same food group. Blood, urine, and fecal samples, alongside food/lifestyle diaries, will be collected from each participant before and after the dietary interventions. The primary endpoint will be the change in plasma LDL-cholesterol levels from baseline. Additional markers include blood pressure, anthropometric parameters, chemical parameters, glucose and lipid-related metabolic markers, incretins, inflammatory and oxidative stress markers, fecal microbiota composition, and short-chain fatty acids. Finally, food waste production will be evaluated through specific validated food diaries. The study has been approved by the Ethical Committee of the University of Milan and the Tuscany Regional Ethics Committee of the Azienda Ospedaliera Universitaria (AOU) - Careggi, Florence. Discussion Results from the PROMENADE study will improve knowledge about the impact of UPF consumption on human and planet health and will contribute to the scientific debate on this topic. Trial registration ClinicalTrials.gov NCT06314932. Registered on March 13, 2024.

Abstract Background Rheumatoid arthritis (RA) is a debilitating inflammatory disorder characterized by an overactive immune system targeting joints, leading to inflammation and intense pain. While current RA therapies effectively alleviate symptoms, they are often associated with significant side effects. This study aimed to assess the anti-inflammatory and anti-arthritic properties of an Ethanolic Extract of Myxopyrum serratulum A.W. Hill (EEMS) using animal models. Results The acute toxicity study with EEMS (2000 mg/kg, p.o.) on rats showed no toxicity or mortality up to the highest dose. Inflammation was induced using carrageenan, and rats were treated with varying doses of EEMS (100, 200, and 400 mg/kg, p.o.) and diclofenac to assess anti-inflammatory effects. Anti-arthritic efficacy was evaluated using Complete Freund’s adjuvant (CFA)-induced inflammation, comparing EEMS to methotrexate. The results revealed dose-dependent anti-inflammatory effects of EEMS and a reversal of arthritic-induced weight loss in treated groups. Paw volume reduction was significant in both EEMS and methotrexate groups. Biochemical analyses showed elevated markers in the arthritic control group, which were normalized by EEMS and methotrexate. Notably, EEMS (400 mg/kg) significantly reduced cathepsin-D levels compared to the positive control. EEMS administration also lowered hepatic lipid peroxidation and increased endogenous antioxidants (SOD, GSH, and GPX). The 200 and 400 mg/kg doses reduced the iNOS/GADPH ratio, while the 400 mg/kg dose restored cellular and joint structure and significantly decreased IL1 levels. Conclusions In conclusion, EEMS demonstrated substantial protective effects, mitigating health risks associated with chronic inflammation such as arthritis. These findings underscore the ethnomedical potential of Myxopyrum serratulum as a promising anti-inflammatory and anti-arthritis agent. The study suggests that EEMS could be a viable alternative or complementary therapy for RA, offering therapeutic benefits with potentially fewer side effects than current treatments.

Abstract Background Gallstone disease poses a global threat to human health and is strongly linked to environmental factors. However, there is currently no data on the presence of rare earth elements (REEs) in human gallstones. This paper investigates the concentration and distribution of REEs in gallstones for the first time, aiming to explore the environmental implications on human health. Methods A total of 25 gallstone samples were collected in Shanghai and the content of REEs was measured by Inductively coupled plasma-Mass Spectrometry (ICP-MS) to explore the distribution of REEs in gallstones. Results The concentration of REEs in gallstones ranged from 4.89 to 190.8 ng/g (mean 39.21). In most of the gallstone analyses, REEs have been detected and generally attributed to environmental exposure or food contamination. The Y/Ho ratio of gallstones was lower than that of continental rocks, similar to that in the blood, indicating limited fractionation during fluid transport processes in the gallbladder. Conclusions The upper continental crust (UCC)-normalized REEs pattern in gallstones showed depletion of light REEs, while most showed enrichment of heavy REEs. Positive Gd anomalies were found in most samples, while few samples suggested anthropogenic influence. Whether exogenous inputs or in vivo biofractionation lead to changes in REEs fractionated patterns require further analyses.

Terrestrial invertebrates in urban ecosystems are extremely species-rich, have many important roles in material flow and energy circulation, and are host to many human pathogens that pose threats to human health. These invertebrates are widely distributed in urban areas, including both out- and in-door environments. Consequently, humans are frequently in contact with them, which provides many opportunities for them to pose human health risks. However, comprehensive knowledge on human pathogen transfer via invertebrates is lacking, with research to date primarily focused on dipterans (e.g., mosquitoes, flies). Here, we take a broad taxonomic approach and review terrestrial invertebrate hosts (incl. mosquitoes, flies, termites, cockroaches, mites, ticks, earthworms, collembola, fleas, snails, and beetles) of human pathogens, with a focus on transmission pathways. We also discuss how urbanization and global warming are likely to influence the communities of invertebrate hosts and have flow-on risks to human health. Finally, we identify current research gaps and provide perspectives on future directions.

Natural carotenoids (CARs) such as β-carotene, astaxanthin, lutein, norbixin, bixin, capsanthin, lycopene, β-Apo-8-carotenal, canthaxanthin, β-apo-8-carotenal-ester, and zeaxanthin are being explored for possible applications in feed, food, cosmeceuticals, and nutraceuticals. Three primary areas of carotenoid research are emerging: (1) encapsulations for improved chemical and physical properties; (2) natural source carotenoid manufacturing; and (3) preclinical, epidemiological, and clinical studies of carotenoids’ potential health benefits. The recent advancements in research on the chemistry and antioxidant activity, marketing strategies, dietary sources, bioavailability, and bioaccessibility, extraction, dietary consumption, encapsulating techniques, and health advantages of carotenoids are all extensively discussed in this review. Carotenoids are pigments found naturally in most fruits and vegetables, algae, plants, and photosynthetic bacteria. Carotenoids cannot be synthesized by humans and must be consumed in the form of food or supplements. There are several roles for carotenoids in human health. Although individual carotenoids may function in different ways, their main action is to act as antioxidants. There are validated techniques for separating and purifying carotenoids, yet, industrial production requires the development of economically viable techniques for larger-scale implementation. Carotenoids have been shown to boost cognitive performance and cardiovascular health, as well as help prevent some types of cancer. Despite evidence for carotenoids’ health benefits, major population-based supplementation trials have yielded conflicting outcomes for several carotenoids. This review includes recent developments in carotenoid metabolism and nutritional and health advantages. It also offers an outlook on future directions in these areas.

In recent years, with the significant rise in global obesity rate, the demand for sugar substitutes such as artificial sweeteners (AS) has soared, but the safety of AS remains controversial. New research from the World Health Organization (WHO) and the journal Nature suggests that long-term consumption of AS may have negative health effects. Currently, the standards on the use of AS in different countries are different, and the mechanism of the health impact of long-term AS consumption is not clear. Therefore, based on recent research results related to AS, this review paper focuses on the human health effect of AS and the current domestic and foreign standards on AS. It elaborates on the relationship between AS and gut microbes, obesity and diabetes, lipid metabolism, cardiovascular disease and cancer, and summarizes the current Codex Alimentarius Commission (CAC), US, EU, Japanese and Chinese standards on AS. In addition, this paper also discusses the key issue of how to determine standards on AS addition in the food industry in order to provide a reference for future research in this field.

Abstract Millets are an important traditional food known for their dietary diversity. They play a key role in ensuring human health and well-being. Millets, which are small-seeded grains cultivated widely in various areas of the world, have emerged as significant contributors to this paradigm shift. They are nutrition powerhouses, that boast raised levels of dietary fibre, protein, vitamins, and minerals. Since they are gluten free, those with celiac disease may utilize them and serve as alternatives to wheat products. The promotion of these grains as a staple food holds significant promise for facing the global challenges of malnutrition, food insecurity, and environmental degradation. Moreover, millets contain bio-active compounds like flavonoids, lignin, phenolic acids reduce inflammation and serve as antioxidants. Millets have positive health benefits related to blood sugar, cardiovascular disease and obesity, and the gastrointestine. This article provides an overview of the functional role of millets as promising food for human health.

It is imperative to say that we are immersed in a sea of microorganisms due to their ubiquitous presence on the planet, from soil to water and air. Human bodies harbor a vast array of microorganisms from both the inside and out called the human microbiome. It is composed of single-celled organisms, including archaea, fungi, viruses, and bacteria, including bacteriophages, where bacteria are the biggest players, and this is collectively referred to as the human microbiome. These organisms have a symbiotic relationship with humans and impact human physiology where they colonize various sites on and in the human body, adapting to specific features of each niche. However, dysbiosis, or the deviation from normal microbial composition, is associated with adverse health effects, disrupted ecosystems, and eco-imbalance in nature. In this review, we delve into the comprehensive oversight of bacteria, their cosmopolitan presence, and their additional applications affecting human lives.

Background and aims: Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid analgesics are recommended to alleviate or reduce pain. Regrettably, many of these drugs may induce bleeding, dyspepsia, cardiac complications, renal issues, and various short- or long-term adverse effects. Consequently, there has been an escalation in the endeavor to develop natural anti-inflammatory medications, driven by the growing number of individuals seeking natural therapies to manage their pain. The polyherbal formulations (Yoyo and Dr. Iguedo Goko bitters) have not assessed their antioxidant and anti-inflammatory activities; hence, this study “in vitro antioxidant and anti-inflammatory activities of selected polyherbal formulations sold in Nigeria.” Methods: The evaluation of antioxidant activity was performed using three assays: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, hydrogen peroxide (H2 O2 ) scavenging activity, and ferric reducing antioxidant power. In vitro, anti-inflammatory efficacy was investigated using the human red blood cell (HRBC) membrane stabilization technique. Results: The DPPH radical scavenging ability result was observed; the IC50 value of Yoyo bitters (40.63±0.90 % at 250 µg/mL) was highest, while Dr. Goko bitters (3.26±0.21% at 50 µg/mL) was lowest. Meanwhile, the positive control (ascorbic acid) had an IC50 value of 93.54±0.57% at 250 µg/mL. The ferric-reducing antioxidant power of the samples was highest in Dr. Goko bitters, 1.96±0.02 % at 250 µg/mL, and lowest in Dr. Goko and Yoyo bitters, 0.46±0.01% at 100 and 50 µg/mL, respectively. The hydrogen peroxide free radical scavenging activity of the samples was highest in Yoyo bitters, 58.0.3±0.60 % at 250 µg/mL, and lowest in Dr. Goko bitters, 7.28±0.02 % at 50 µg/mL. The anti-inflammatory findings indicate that Yoyo bitters exhibited the highest percentage protection (89.46±6.11%) at a concentration of 1000 μg/mL, while the lowest percentage protection (26.62±1.13%) was observed at a concentration of 200 μg/mL. The reference standard diclofenac sodium has a percentage of 90.46±1.44 at a concentration of 1000 μg/mL. Meanwhile, the poly-herbal formulations had the highest and lowest total phenolic concentrations in Yoyo bitters (97.52±1.43 mg GAE/g at 250 µg/mL), and Dr. Goko bitters (47.3±1.44 mg GAE/g at 50 µg/mL), respectively. Conclusion: The findings suggest that the formulations might not have effective antioxidant and anti-inflammatory activities when compared with the reference standard drugs (ascorbic acid and diclofenac sodium), respectively.

Deteriorating water quality poses a substantial risk to human health, with billions at risk of waterborne diseases due to contamination. Insufficient water quality data augment risks as conventional monitoring methods lack comprehensive coverage. Technologies like the Internet of Things and machine learning offer real-time water quality monitoring and classification. IoT nodes often provide point data insufficient for monitoring the quality of entire water bodies. Remote sensing, though useful, has limitations such as measuring only optically active parameters and being affected by climate and resolution issues. To address these challenges, an unmanned surface vehicle named `AquaDrone' has been developed. AquaDrone traverses water bodies, collecting data of four key parameters (pH, dissolved oxygen, electrical conductivity, and temperature) along with GPS coordinates. The data is transmitted to a web portal via LoRa communication and Wi-Fi, where visualizations like data tables, trendlines and color-coded heatmaps are generated. A multilayer perceptron classifies water quality into five categories, aiding in real-time classification. A comparative analysis of various oversampling techniques has been conducted in the context of water quality classification. The AquaDrone offers a feasible solution for monitoring quality of small to medium-sized water bodies, crucial for safeguarding public health. HIGHLIGHTS AquaDrone measures four physicochemical parameters of water along with GPS coordinates to monitor water quality in real-time.; A multilayer perceptron classifies water quality into five categories, with oversampling used to enhance model training.; AquaDrone wirelessly transmits data to the web portal, where trendlines, data table and a color-coded heatmap are generated to visualize water quality.; This ensures effective real-time monitoring in small to medium-sized water bodies, protecting both water sources and human health.;

A rising corpus of research has shown the beneficial effects of probiotic Lactobacilli on human health, contributing to the growing popularity of these microorganisms in recent decades. The gastrointestinal and urinary tracts are home to these bacteria, which play a vital role in the microbial flora of both humans and animals. The Lactobacillus probiotic, i.e, Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus reuteri, and Lactobacillus bulgaricus, are highly recognized for their remarkable probiotic qualities. The current study aims to highlight the beneficial effects of probiotics in different health conditions, point out the research gap, and highlight the future directives for the safe use of these probiotics in several health issues. Most importantly, we have added the most recent literature related to the characteristics and usage of these probiotics in clinical and pre-clinical settings. Based on the above statement, we believe that this is the first report on the application of probiotics in human diseases. By providing a deeper knowledge of the complex functions these probiotics play in both human and animal health, our analysis will direct future studies and developments in this rapidly developing field.

Forests provide a variety of ecosystem services that contribute in various ways to human well-being. In times of land-use pressures, urbanisation, and nature degradation, the societal demand for forest-based therapeutic uses is increasing. Although nature-related therapies and the beneficial effects of nature on health and well-being are an old concept in cultures such as Asia and, more recently, Europe, forest therapy offers are increasingly taking hold in the forest recreation landscape. This Commentary paper identifies recent forest therapy offers and research in Asia and Europe that focus on the therapeutic effects of forests and examine their underlying rationales, practices, and status. In particular, we elaborate the socioeconomic potential of forest therapy to contribute to human health and sustainable forest management. Based on a scoping review on forest therapy offers and research, we found that countries such as Japan and South Korea are ahead of European countries in the professionalization of forest therapy offers and respective studies. While the number of studies that demonstrate the positive health benefits of forests are increasing, there is a lack of understanding the link with forest management approaches and forest and health policies. A lack of socioeconomic evaluation hinders its successful integration into policy frameworks, and prevents its use as an alternative forestry product or preventive medical treatment. For forest therapy to become part of the forestry portfolio and a medical alternative, we recommend: • Interdisciplinary research approaches and new actor alliances that link societal demands for forest therapy with insights from forest management and medical health research, • Transdisciplinary research and multi-actor approaches to link insights from forest and medical research with practitioners’ skills for forest management, service design, and communication, • To identify trade-offs and conflict potentials with forest therapy, for example in relation to timber production or questions of insurance in case of injuries by falling branches etc., that allow to develop integrated and sustainable solutions, • Policy backup and economic support for forest managers and owners to compensate for their efforts to manage their forests for therapeutic purposes • Recognition of forest therapy as an explicit part of the forestry portfolio and an alternative medical offer for clinical treatments.

In Arctic populations, a primary route of exposure to contaminants is through the diet. The health risks associated with these exposures can be characterised by conducting human health risk assessments. However, while there is guidance from many international and national organisations, there are limited examples of human health risk assessment in the Arctic. The 2022 AMAP Human Health Assessment Report was the first AMAP report to describe, in one place, the utility of food-based, dietary intake-based and human tissue-based contaminant data in estimating risk. Here, we present available tools, case studies and challenges associated with conducting human health risk assessments in the Arctic. Future efforts in the Arctic should be able to use this information to best interpret human exposure to contaminants in a risk-based context.

Appetite, a crucial aspect regulated by both the central nervous system and peripheral hormones, is influenced by the composition and dynamics of the intestinal microbiota, as evidenced by recent research. This review highlights the role of intestinal microbiota in appetite regulation, elucidating the involvement of various pathways. Notably, the metabolites generated by intestinal microorganisms, including short-chain fatty acids, bile acids, and amino acid derivatives, play a pivotal role in this intricate process. Furthermore, intestinal microorganisms contribute to appetite regulation by modulating nutritional perception, neural signal transmission, and hormone secretion within the digestive system. Consequently, manipulating and modulating the intestinal microbiota represent innovative strategies for ameliorating appetite-related disorders. This paper provides a comprehensive review of the effects of gut microbes and their metabolites on the central nervous system and host appetite. By exploring their potential regulatory pathways and mechanisms, this study aims to enhance our understanding of how gut microbes influence appetite regulation in the host.

Plastics play a crucial role in nearly each aspect of societal production and everyday life, therefore making them one of the most widespread pollutants on a global scale. Because synthetic plastics are not entirely biodegradable, they often remain in the environment and fragment into micro- and nanoplastic particles. The detrimental impacts of nanoplastics on the environment and human health have received substantial worldwide interest in recent years. However, the effects of nanoplastics on human health have not yet been fully explored. Our study aimed to investigate the cytotoxic effects of polystyrene nanoplastics on two distinct mammalian cell lines: normal rat kidney cells (NRK52E) and human umbilical vein endothelial cells (HUVECs). Results showed that polystyrene nanoplastics generate cytotoxicity in both NRK52E and HUVECs in a concentration- and time-dependent manner. Additionally, polystyrene nanoplastics induced pro-oxidant levels (e.g., reactive oxygen species and hydrogen peroxide) and reduced antioxidants (glutathione content and glutathione peroxidase enzyme activity) in both types of cells. We also found that polystyrene nanoplastics cause apoptosis in both NRK52E and HUVECs, as shown by the activation of the caspase-3 enzyme and the loss of mitochondrial membrane potential. Interestingly, it was noticed that the vulnerability of HUVECs cells against polystyrene nanoplastics was a little higher than that of NRK52E cells. Also, the cell toxicity caused by polystyrene nanoplastics in NRK52E and HUVECs was effectively alleviated by co-exposure to a reactive oxygen species inhibitor, N-acetyl-cysteine. This suggests that oxidative stress could be one of the possible pathways by which polystyrene nanoplastics cause cell toxicity. The present work warrants future study to explore the toxicity mechanisms of polystyrene nanoplastics in appropriate in vivo models.

Most of the short-chain fatty acids (SCFAs) are produced by Bifidobacterium, Lactobacillus, Lachnospiraceae, Blautia, Coprococcus, Roseburia, Facealibacterium and Oscillospira. Butyrate (C4H7O2−) supplies 70% of energy to intestinal epithelial cells (IECs), supports tight-junction protein formation, induces the production of inflammatory cytokines, and inhibits histone deacetylase (HDAC). Butyrate is also associated with the recovery of brain trauma, improvement of dementia, the alleviation of autoimmune encephalitis, and several intestinal disorders. Low levels of SCFAs are associated with hypertension, cardiovascular disease (CVD), strokes, obesity, and diabetes mellitus. Cis-palmitoleic acid (C16H30O2), a mono-unsaturated fatty acid (MUFA), increases insulin sensitivity and reduces the risk of developing CVD. Lipokine palmitoleic acid reduces the expression of pro-inflammatory cytokines IL-1β (pro-IL1β), tumor necrosis factor α (TNF-α), and isoleucine 6 (IL-6). Polyunsaturated fatty acids (PUFAs), such as omega-3 and omega-6, are supplied through the diet. The conversion of PUFAs by cyclooxygenases (COX) and lipoxygenases (LOX) leads to the production of anti-inflammatory prostaglandins and leukotrienes. Oxidation of linoleic acid (LA, C18H32O2), an omega-6 essential fatty acid, leads to the formation of 13-hydroperoxy octadecadienoic acid (13-HPODE, C18H32O4), which induces pro-inflammatory cytokines. Omega-3 PUFAs, such as eicosapentaenoic acid (EPA, C20H30O2) and docosahexaenoic acid (DHA, C22H32O2), lower triglyceride levels, lower the risk of developing some sort of cancers, Alzheimer’s disease and dementia. In this review, the importance of SCFAs, MUFAs, PUFAs, and saturated fatty acids (SFAs) on human health is discussed. The use of fatty acids in the treatment of diseases is investigated.

Most modern cities suffer from urban air pollution caused by human activity such as traffic and other sources. Various pollutants in the environment may pose a threat to the health of commuters. The objective of this study is to assess the indoor air quality (IAQ) in MRT purple line trains serving the north-western area of Bangkok in order to determine any potential impacts on human health. The monitored parameters include total volatile organic compounds (TVOCs), temperature, relative humidity, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), formaldehyde (CH2O), and fine particulate matter (PM2.5). The indoor air pollutant concentrations in the MRT remained within the permissible thresholds. The results of the correlation analysis reveal that relative humidity (RH) and PM2.5 are positively correlated in both the wintertime and summertime measurement campaigns. In contrast, CO2 correlated with temperature in the wintertime and CO in the rainy season. Bacterial and fungal loads were estimated during various measurement campaigns in MRT. Fungi and bacterial loads were higher in the MRT trains during the wintertime and rainy season campaigns. The IAQ of MRT train in Bangkok is within the satisfactory and excellent category of air quality index (AQI). The inhaled doses of PM2.5, CO, and VOCs were also estimated to identify their health effects on commuters. The inhaled dose of PM2.5 was comparatively higher than other pollutants. In this study, a general perspective of the IAQ in the MRT system was provided. It is recommended to conduct more research studies on various MRT lines in Bangkok to further investigate the levels of bacteria, fungi, TVOCs, O3, and PM. Additionally, the ventilation mode in MRT needs to be investigated as it is the main factor affecting the IAQ.

Proteins are usually composed of carbon, nitrogen, hydrogen, oxygen, and sulfur, resulting in too many amino acid molecules with interlinked peptide bonds. A careful analysis of other protein-rich choices is required because of the depletion of conventional protein resources and the need to meet the dietary demands of the increasing global population. The prime motive for creating concentrates and isolates from a protein source is to increase the concentration of proteins by removing non-protein constituents, allowing the use of a lower amount of protein for food formulation to provide specific nutritional and functional properties. Protein concentrates are a possible alternative that come from a range of sources, including dairy products, plants, and insects. Their extraction strategies, which range from conventional solvent extraction to cutting-edge approaches, such as membrane separation and enzyme-assisted procedures, provide opportunities to maximize yield, maintain nutritional value, and reduce environmental impact. These concentrates are used in the food sector to improve dietary profiles, formulate functional foods, and meet growing demand for plant-based and alternative protein sources. This review advances our understanding of this crucial element in the search for nutrient-dense and sustainable protein sources by clarifying their origins, extraction techniques, and uses.

AbstractThe fields of agronomy and pesticides have assumed significant roles in contemporary society. Pesticides can have adverse effects on human health, both in the short and long term. We have conducted a comprehensive analysis of the various categories of pesticides, providing a thorough examination of their modes of operation, prevalence, and global utilization. A critical review of reported research has been conducted to investigate the carcinogenic effects of agricultural pesticide use on human health. The widespread utilization of malathion and parathion for pest management indicates that individual occupational choices significantly impact their exposure to these chemicals. Pesticides can cause neurological abnormalities, reproductive problems, respiratory irritations, ecological disturbance, and the emergence of pest resistance, among other sublethal consequences beyond their carcinogenicity (breast cancer, lymphomas, multiple myeloma, bladder cancer, and leukemia). Ultimately, there is an anticipation for a forthcoming surge in endeavors to mitigate the utilization of hazardous pesticides and the consequent peril they pose to human well-being and the ecosystem.

Heavy metals (HMs) contamination significantly threatens plants, animals, aquatic ecosystems, and public health. HMs’ accumulation in aquatic environments has become a serious environmental issue due to their high stability, bioaccumulation, and biomagnification properties. These metals enter ecosystems through both natural sources and/or human activities. The toxicity of HMs poses a threat to the aquaculture sector’s sustainability by negatively affecting fish growth, reproduction, and overall physiology. Exposure to HMs in various forms can cause environmental damage, which may affect human health through direct poisoning symptoms or other adverse effects. One such effect is the increased production of reactive oxygen species (ROS), crucial metabolites that modulate the functions of pathogenic organisms and lead to oxidative stress. This, in turn, can contribute to the onset and exacerbation of numerous diseases that threaten human health. This review article examines the potential sources of HMs contamination in aquatic organisms, the impact of this contamination on the generation of ROS, and the implications for human health resulting from the consumption of contaminated aquatic products.

Microplastics (MPs), defined as plastic particles smaller than 5 mm, are increasingly recognized as environmental contaminants with potential health risks. These emerge as breakdown products of larger plastics and are omnipresent in marine, freshwater, and terrestrial ecosystems. They are primarily composed of polymers such as polyethylene, polypropylene, polystyrene, and additives that enhance their performance. MPs also adsorb harmful environmental chemicals like persistent organic pollutants and heavy metals, posing risks to human and environmental health. Human exposure to MPs occurs mainly through ingestion and inhalation, with MPs detected in food products, water, and even the air. MPs have been shown to accumulate in the gastrointestinal tract, disrupting the gut microbiome, and causing dysbiosis-a harmful imbalance between beneficial and harmful bacteria. This disruption has been linked to various health issues, including gastrointestinal disorders, systemic inflammation, and chronic diseases. Furthermore, the gut-brain axis may be affected, with potential neuroinflammatory consequences. As research continues to unravel the health impacts of MP exposure, understanding the mechanisms of accumulation and the broader implications on human health is crucial. This review highlights the effects of MPs on human health, emphasizing their impact on the gut microbiome. We discuss the potential connections between MP exposure and cardiometabolic and inflammatory diseases, and disorders related to the Gut-Brain Axis. By synthesizing the latest research, this work sheds light on the silent yet pervasive threat posed by MPs and underscores the importance of further studies to understand their health impacts fully.

Liquid smoke, a product of the pyrolysis process, includes components such as phenol, furfural, and ketones, and has acidic characteristics. Liquid smoke from various biomass sources has been used as a natural preservative worldwide and reported to be safe in humans. As a bio-economic product, liquid smoke has human health benefits. This review analyzes and describes the health benefits of liquid smoke from various biomass sources, according to in silico, in vitro, and in vivo studies. A systematic review following PRISMA guidelines was conducted to identify published reports of liquid smoke from various biomass sources. The anti-inflammatory, anti-bacterial, anti-diabetic, wound healing, and anti-periodontitis activity of liquid smoke was analyzed. Prior research has investigated liquid smoke produced through pyrolysis of various biomass types, such as rice husks (Oryza sativa), coconut shells (Cocos nucifera L.), palm kernels (Elaeis guineensis Jacq.), cocoa pods (Theobroma cacao L.), tian op, and hickory (Carya tomentosa (Lam.) Nutt.), as well as commercial liquid smoke. Toxicity testing, and in vitro and in vivo studies, are required for the assessment of health benefits. Therapeutic benefits of liquid smoke including anti-oxidant, anti-inflammatory, anti-nociceptive, anti-bacterial, anti-fungal, and anti-viral activity have been described. Further health benefits include anti-diabetic, anti-periodontitis, wound healing, and ulcer healing activity. These findings increase the use value of liquid smoke as a natural product with human health benefits.

This review summarizes studies on the relationships between climate change and Valley Fever (VF), also termed Coccidioidomycosis, a potentially fatal upper-respiratory fungal infection caused by the pathogenic fungi, C. immitis or C. posadasii. The intensified onset of climate change has caused frequencies and possibly intensities of natural hazard events like dust storms and drought to increase, which has been correlated with greater prevalence of VF. These events, followed by changes in patterns of precipitation, not only pick up dust and spread it throughout the air, but also boost the growth and spread of Coccidioides. In California alone, cases of VF have increased fivefold from 2001 to 2021, and are expected to continue to increase. From 1999 to 2019, there was an average of 200 deaths per year caused by VF in the United States. The number of deaths caused by VF fluctuates year to year, but because more infections are predicted to occur due to a changing climate, deaths are expected to rise; thus, the rising prevalence of the disease is becoming a larger focus of the scientific community and poses an increased threat to public health. By reviewing recent and past studies on Coccidioidomycosis and its relationships with climate factors, we categorize future impacts of this disease on the United States, and highlight areas that need more study. Factors affecting the incidence of VF, such as modes of dispersal and the optimum environment for Coccidioides growth, that could potentially increase its prevalence as weather patterns change are discussed and how the endemic regions could be affected are assessed. In general, regions of the United States, including California and Arizona, where VF is endemic, are expanding and incidences of VF are increasing in those areas. The surrounding southern states, including Nevada, New Mexico, Utah, and Texas, are experiencing similar changes. In addition, the entire endemic region of the United States is predicted to spread northward as drought is prolonged and temperatures steadily increase. The findings from the keyword search from eight databases indicate that more studies on VF and its relation to dust and climate are needed especially for endemic states like Nevada that are currently not adequately studied. Overall, results of this survey summarize mechanisms and climate factors that might drive spread of VF and describes trends of incidence of VF in endemic states and predicted likely trends that might occur under a changing climate. Through reviewing recent and past studies of Coccidioidomycosis and its relationships with climate factors, future impacts of this disease have been categorized and speculated on effects it might have on the United States. Better understanding of how climate factors affect VF as well as identifying regions that require more research could inform both environmental managers and medical professionals with the resources needed to make more accurate predictions, design better mitigation strategies, send timely warnings, and protect public health.Shortened versionThis review explores how climate change affects Valley Fever (VF), a dangerous fungal infection caused by C. immitis or C. posadasii. Climate change has increased natural hazard events such as dust storms and droughts, which have caused the spread of VF. Cases of the disease have increased fivefold between 2001 and 2021 in California alone, and it poses an increasing threat to public health. The review summarizes mechanisms that drive the spread of VF and highlights trends in endemic states under a changing climate. It recommends more studies on VF and its relation to dust and climate, especially for states like Nevada. Identifying regions that require more research can help make more accurate predictions, design better mitigation strategies, send timely warnings, and protect public health.

Abstract There is a recent trend showing an uptick in the artificial sweetener's usage, particularly the nonnourishing variety. The allure of a low‐calorie choice that lets people indulge in their sweet tooths while consuming less calories overall is what motivates this. Children's food products often contain a substantial number of artificial sweeteners due to their properties that aid in moisture retention, act as fillers, and serve as bulking agents. This article provides a comprehensive overview of artificial sweeteners and influences in human wealth. Studies have linked the use of artificial sweeteners to premature birth, highlighting the teratogenic potential of these compounds, particularly in beverages. Pregnant women who incorporate nonnutritive sweeteners into their diet during pregnancy are more likely to have children with birth defects, as indicated by studies on the subject. Artificial sweeteners should not be added to food for children because studies show that eating them while a child's body is still developing might disturb the balance of gut microbiota and cause potential problems like heart disease, stroke, and cognitive decline. The ingestion of nonnourishing sweeteners has adverse effects on the fertility of both men and women. Studies indicate that exceeding the recommended daily consumption that the FDA has set for artificial sweeteners can result in conditions of infertility for both genders. Additionally, there is a connection between the onset of cancer and the use of artificial sweeteners. Presently, a considerable amount of research relies on animal models rather than human ones, creating a notable gap in research. The limitation of extensive human model studies represents a drawback in validating results. Furthermore, there is a necessity for increased research focused on advancing techniques that can minimize the adverse effects of artificial sweeteners, making them more suitable for addressing issues related to obesity and various types of diabetes.

Abstract The outbreak of coronavirus disease 2019 (COVID‐19) stimulates a body of studies for better investigating the essential mechanisms and clinical characteristics of this disease. Notwithstanding, the underlying mechanisms of multiple organ failure (MOF) remain unclear. Understanding the mechanism of COVID‐19‐stimulated programmed cell death (RCD) may contribute to better strategies for these patients. Based on the exploration of COVID‐19‐related basic science reports and clinical research, we speculate that ferroptosis, a recently identified RCD, might be a substantial stimulator for MOF in COVID‐19, and it may act as a novel treatment target. However, the published investigations to determine how ferroptosis works in severe acute respiratory syndrome coronavirus 2 infection are still lacking. This review reveals new crucial missing links in our prevailing understanding of the mechanisms that ferroptosis‐triggered MOF in COVID‐19 patients. We also specifically summarize several literatures evidence about the functional food components as the nutritional supplement for COVID‐19 by its characteristics of ferroptosis inhibition. We hope this hypothesis may launch a new wave of studies to unveil the relationship between ferroptosis and COVID‐19 and explore more ferroptosis‐related functional food components in daily life for preventing the COVID‐19 and/or to improve the outcome during therapy.

Honey is an attractive functional food that often becomes a subject of clinical studies on the treatment of diverse diseases. However, the clinical efficacy of honey is rather controversial due, at least in part, to its variable composition and botanical origin as well as thermal processing or improper storage conditions. This review addresses the importance of honey quality standards and in vitro testing of the biological properties of honey prior to performing clinical studies, which can have a great impact on clinical outcomes. It focused on recently performed meta-analyses and systematic reviews where honey was used in the management of various disorders including respiratory tract infections, and metabolic and cardiometabolic diseases, with the goal of characterising the honeys used in clinical studies. In addition, it provides recommendations for the use and storage of honey for clinical testing. The vast majority of clinical studies included in meta-analyses do not provide any information about honey quality parameters. In fact, indicators of thermal damage or prolonged storage of honey were analysed only in one clinical study. This observation highlights on the alarming status of honey quality in clinical studies. Furthermore, in vitro biological properties of the analysed honeys were assessed in two clinical studies. Therefore, this review strongly advocates the clinical use of only fully characterised honey samples of known botanical origin with proven in vitro biological functionality and no or minimal thermal processing.

In recent years, overexplorations of ore and the growth of industries are the prime factors in the release of heavy metals in environments. As a result, the food crops and water bodies are contaminated with metals which may have several adverse effects on the health of humans and other living species. These metals and metalloids, such as Zn, Cu, Mn, Ni, Cr, Pb, Cd, and As, upset the biochemical pathways of metabolite synthesis in living organisms and contribute to the etiology of different diseases. Microorganisms include bacteria, archaea, viruses, and many unicellular eukaryotes, which can span three domains of life—Archaea, Bacteria, and Eukarya—and some microorganisms, such as cyanobacteria, have shown high efficiency in the biosorption rate of heavy metals. Cyanobacteria are suitable for bioremediation as they can grow in adverse environments, have a less negative impact on the surrounding environment, and are relatively cheaper to manage. The structure of cyanobacteria has shown no extensive internal-bound membranes, so it can directly employ the physiological mechanisms to uptake heavy metals from contamination sites. Such biochemical makeups are suitable for managing and bioremediating heavy metal concentrations in polluted environments. This review aims to explore the potential of cyanobacteria in the bioremediation of heavy metals and metalloids in water bodies. Additionally, we have identified the prospects for enhancing bioremediation effectiveness.

Microplastics (MPs) are pervasive across ecosystems, likely posing significant environmental and health risks based on more and more evidence. In this study, we searched through the Web of Science Core Collection and obtained 1039 papers for visualization and analysis. In order to discuss the chemical composition, migration, transformation and potential risk of MPs, 135 sets of relevant data in soil, water, and atmosphere were collected in China as a typical region, which is a hotspot region for investigation of MPs. The results showed that the primary polymer categories of MPs in the environment to be polypropylene, polyethylene, and polystyrene. The soil contains a significant quantity of MPs, averaging at 12,107.42 items·kgdw−1, while water contains averaging at 97,271.18 items m−3. The total pollution load indexes for all three environments are at risk level I. Based on current risk assessment methods, the potential ecological risk of MPs is low. However, based on the polymer components, migration and transformation patterns, and especially the complexes with other pollutants, it indicates an increasing indirect risk. Interactions with some other pollutants are likely amplify the ecological and health risks associated with MPs. Aggregative results showed that the present risk assessment models could not assess the risks of MPs well. Thus, we suggested develop a risk assessment methodology for MPs based on relevant research progress. Some factors such as the size and form of MPs, sources and distribution, bioaccumulation, social acceptance and economic costs could be considered adding in the present risk assessment models. Finally, promotion of development and application of green chemically synthesized bioplastics such as using synthetic biology to help degrade plastics would be an alternative and sustainable option to relieve the adverse environmental and health concerns of MPs.

Ganoderma lucidum (GL) is a potent source of bioactive compounds with diverse nutritional and pharmacological benefits. Its popularity as a dietary supplement, herbal remedy, and wellness product is steadily on the rise. Furthermore, the standardized advancement of the GL industry has facilitated reliable sourcing of raw materials and quality control measures, enhancing its utilization and endorsement in the realms of nutritional science and pharmaceutical research. This article provides a comprehensive overview of the recent advancements in research pertaining to the bioactive components of GL, particularly polysaccharides (GLP) and triterpenes (GLTs) as well as highlights the latest findings regarding their beneficial effects on human diseases, including anticancer, antidiabetes, liver protection and other aspects (such as regulating gut microbiota, antioxidant, antimicrobial, antiinflammatory and immune regulation). Furthermore, we summarized the potential applications of GL in the food and pharmaceutical sectors, while also examining the current status of standardization throughout the entire industrial chain of GL, both domestically and internationally. These information offer an insight and guidance for the prospects of industrial development and the innovative advancement of GL within the global health industry.

Earth’s marine ecosystems are changing rapidly, in large part owing to the damaging effects of human activities. Unless humans find better ways of interacting with the seas and oceans, the marine resources upon which we rely will diminish as more ecosystems collapse. The consequences for human health and wellbeing will be severe. The meta-discipline of Oceans and Human Health has catalogued how the oceans and their constituents benefit human lives. Examples include access to seafood, pharmaceuticals and physical and mental health benefits. This interdisciplinary research effort has also revealed how the integrated impact of anthropogenic activities has disrupted ocean processes resulting in extensive losses of marine biodiversity, increasing chemical and microbial pollution, proliferation of harmful algal blooms and increased coastal inundation, all of which threaten human populations. In response, non-governmental organizations and national governments have established various agreements and treaties to prevent further damage, restore what has been lost and grasp new economic opportunities. Nevertheless, ocean-related risks continue to escalate rapidly in the absence of political commitment. New thinking regarding the interconnectedness of all human/ocean interactions is required to remove the barriers and impediments that hamper tackling the wicked problem of fostering health and wellbeing while achieving ocean sustainability.

Acting as ‘antioxidants’, phenolic compounds have been shown to have a potential protective effect against a wide range of noncommunicable diseases. However, their content in plant-based products – and, in turn, their potential benefits – might be affected by the thermal procedures used in food cooking. In light of this, the aim of this work was a characterization of Patata Rossa di Colfiorito (PRC, an Italian PGI red-skinned potato) and an investigation of the impact of cooking and storage on its bioactive compounds, phenolic content, and antioxidant activity. After the harvesting (T0), samples were analyzed using instrumental analysis (e.g., HPLC-ESI-MS/MS) and a set of chemical assays (total phenolic content, 2,2-Diphenyl-1-picrylhydrazyl – DPPH, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) – ABTS, and oxygen radical absorbance capacity – ORAC assays). Analyses were also performed on boiled, pressure-cooked and one-month-stored (T1) products. A commercial red-skinned potato (RSP) was also analyzed.Overall, compared with the raw product, both boiling and pressure-cooking led to a significant increase in bioactive compounds (raw: 168.15 mg kg−1 of fresh matter, FM; boiled: 398.92 mg kg−1 FM; pressure-cooked: 309.24 mg kg−1 FM), total phenolic content and antioxidant activity measured by DPPH and ABTS assays.PRC samples showed higher content in bioactive compounds, TPC values and antioxidant activity compared with commercial RSP (with some sporadic exceptions in ORAC values). Interestingly, one month of domestic storage did not affect the freshly harvested product’s features.In conclusion, these results highlighted the quality of this local product and its property to withstand thermal processing and storage. We believe that the results we have obtained should be taken into consideration by health professionals, at both local and national levels, and that PRC deserves to be further studied to investigate its potential human health benefits, as well.

The food security of Lima—Peru’s capital city, which shelters over 30% of the total country’s population—depends on the food production of its nearest agricultural areas, the Chancay-Huaral and Chillón valleys, wherein agrochemicals are widely used. This study primarily aimed to determine the characteristics of pesticide use in these two valleys, located 83 and 30 km north of Lima City, respectively. A second aim was to assess whether proximity to Lima provides access to technical assistance regarding agricultural activities. A questionnaire-based survey assessing socioeconomic aspects, occupational exposure, and agrochemical-related knowledge was conducted on a sample of 102 participants (farmers and fieldworkers). The results revealed that the average age for starting to handle pesticides was 15 years, while life-long occupational-exposure averaged 30 years. Most pesticides used were organophosphates and carbamates. Personal protective equipment was not used and, therefore, dermal exposure and inhalation were major routes of intoxication. Despite their proximity to Lima, both valleys lack an official agronomic advisory agency, and this void has been occupied by agrochemical manufacturing companies and trading houses focused on increasing their sales. Based on the results, it is urgent to implement an official technical advisory service and a capacity-building program on pesticide use in Peru, as well as the implementation of measures for improved control, trade, and storage of pesticides. Simultaneously, a permanent epidemiological surveillance at the country level is needed to improve public health and to contribute to achieving the Sustainable Development Goals of the United Nations’ 2030 Agenda in Peru.

Abstract This study was designed to evaluate the concentration of heavy metals (HMs) in the north of Ahvaz, southwest Iran. The soil samples were collected from the agricultural farm and riverside in Karun, for the investigation of the environmental impacts of the selected HMs in the soil of the Weiss and Arab Assad regions. For soil sampling in a period, nine farms were selected from each region, and 10 samples were taken from each agricultural farm. Zoning was done using GIS. The highest of Contamination Factor, Enrichment factor and geo-accumulation index of HMs for Cd (7.84, 73.92 and 2.38), and the lowest value of this index for Cr (0.21, 1.98 and − 2.82), respectively. Furthermore of the farm soil showed that the most toxic effect is related to Cd. The HMs contamination indices of the soil samples showed that the studied HMs had contaminated the agricultural fields. Moreover, the zoning maps of the Co, Cu, Pb and Cr showed that they had not contaminated the soil of wheat fields, but Cd and Zn revealed high contamination levels. The zoning of Ni concentration distribution showed that this metal contamination came from both anthropogenic aspects and geological activities in the region. According to our findings, the EF illustrated high levels of pollution for Cd, Cu, Cr, Pb, Ni, Fe, Mn, Co, and Zn, which seems to be in accordance with the accumulation of agricultural fertilizers (phosphate and nitrate), industrial and human activities in the region.

Abstract Today, the deterioration of water quality is still a big concern among researchers, whose essential strategy is to develop water purification processes. The presence of contamination of emerging concerns has become a challenging issue, their toxicity, persistence in the aquatic environment, and their mass accumulation at low concentrations have had adverse effects on human health and aquatic organisms. Biological disposal or improper disposal, these pollutants cause serious damage to the population of non-target groups. Penicillin is a broad-spectrum group of beta-lactam antibiotics that has caused concerns for human health and the environment due to its slow decomposition in water sources. This review article focuses on the application of advanced oxidation processes to eliminate these antibiotics. Several studies have investigated the effects of different parameters on species with both ultraviolet and non-ultraviolet light. The results have been promising, with an average efficiency above 80% for these processes. Despite the limitations of various methods, the knowledge gap in future studies has been addressed by proposing the use of Fenton, ultrasound method and Integrated processes like Synergistic Remediation-Advanced Oxidation Processes.

Despite the existence of many interventions to mitigate or adapt to the health effects of climate change, their effectiveness remains unclear. Here, we introduce the Comprehensive Evaluation Framework for Intervention on Health Effects of Ambient Temperature to evaluate study designs and effects of intervention studies. The framework comprises three types of interventions: proactive, indirect, and direct, and four categories of indicators: classification, methods, scope, and effects. We trialed the framework by an evaluation of existing intervention studies. The evaluation revealed that each intervention has its own applicable characteristics in terms of effectiveness, feasibility, and generalizability scores. We expanded the framework's potential by offering a list of intervention recommendations in different scenarios. Future applications are then explored to establish models of the relationship between study designs and intervention effects, facilitating effective interventions to address the health effects of ambient temperature under climate change.

Dye-assisted method for the analysis of fluoride content of water has been developed in this study using dyes obtained from some flowering plants. This was done to evaluate the potentials of locally accessible dyes in spectrophotometrically detecting F– levels in fluoride-containing water samples. Dye solutions obtained from scarlet jungle flame, Hibiscus flower, Peacock flower or Barbados pride, Royal poinciana, Pink bauhinia, Barbados lily, or Easter lily were adopted to monitor absorbance and corresponding concentrations of serially prepared F− concentrations in a range of 0.001–0.012 ppm. Dye from the Hibiscus flower gave an optimal performance with R2 = 0.9792. Using this dye, the F– content in water samples obtained from tap waters from Moremi Estate, Modomo, Asherifa, Postgraduate Hall of Obafemi Awolowo University, Ile-Ife, and a well water sample from Modomo gave 0.052, 0.053, 0.053, 0.058, and 0.061 ppm, respectively. A comparison of these values indicated that all the water samples monitored were safe for human consumption without experiencing health challenges as the maximum F– limit for potable water recommended by WHO was not exceeded. This study concluded that dye from Hibiscus flower could satisfactorily assist in monitoring F– content in water where ion-selective electrodes are not readily accessible. HIGHLIGHTS Determination of fluoride in water.; Use of natural dye in the determination of fluoride.; Use of environmental friendly dye in the determination of fluoride in water.; Paucity of information on the concentration of fluoride in water sample of the studied area.;

Abstract Plant protection measures are necessary to prevent pests and diseases from attacking and destroying crop plants and to meet consumer demands for agricultural produce. In the last decades the use of chemical pesticides has largely increased. Farmers are looking for alternatives. Biopesticides should be considered a sustainable solution. They may be less toxic than chemical pesticides, be very specific to the target pest, decompose quickly, and be less likely to cause resistance. On the other hand, lower efficacy and higher costs are two disadvantages of many biopesticides. Biopesticides include macroorganisms, natural compounds and microorganisms. Microbial pesticides are the most widely used and studied class of biopesticides. The greatest difference between microbial and chemical pesticides is the ability of the former to potentially multiply in the environment and on the crop plant after application. The data requirements for the European Union and the United States Environmental Protection Agency are highlighted, as these regulatory processes are the most followed in regions where local regulations for biopesticide products are not available or vague. New Approach Methods already proposed or harmonized for chemical pesticides are presented and discussed with respect to their use in evaluating microbial pesticide formulations. Evaluating the microbials themselves is not as simple as using the same validated New Approach Methods as for synthetic pesticides. Therefore, the authors suggest considering New Approach Method strategies specifically for microbials and global harmonization with acceptability with the advancements of such approaches. Further discussion is needed and greatly appreciated by the experts.
