- Abstract
This study aims to develop an in vitro barrier effect test over biomimetic membrane, which is useful to establish the film forming ability of a substance-based medical device (SB-MD). The method contemplates a multiparametric approach including: i) the measurement of the transmembrane passage of a molecular-like marker over a lipid-impregnated biomimetic membrane (simulating the skin and gastro-intestinal and buccal tissues) by using a static diffusion cell apparatus (Franz cell); and ii) the evaluation of the integrity of the membrane (colorimetric test). In the first step, a series of lipid-impregnated biomimetic membranes (simulating gastro-intestinal, buccal, and skin tissues) were implemented and their permeability performance validated using model drugs (caffeine and acyclovir) by referring to literature data. As a result, the apparent permeability (Papp) of caffeine over the biomimetic gastro-intestinal membrane (Papp = 30.5E-6 cm/s) was roughly comparable to the literature values obtained with Caco-2 cell line membrane (Papp = 30.8E-6 cm/s) and with the Franz cell method (Papp = 36.2E-6 cm/s). Acyclovir was shown to be a poorly permeable substance both in the literature and experimental data. Following this step, the permeability study was extended to both biomimetic buccal and skin (STRAT-M®) membranes: for caffeine, biomimetic gastro-intestinal membrane was the most permeable (Papp = 30.5E-6 cm/s), followed by the buccal (Papp = 18.2E-6 cm/s) then the skin (Papp = 0.5E-6 cm/s) biomimetic membranes. In a second part of the work, the barrier effect test was developed following a similar permeability-like approach. The protocol was designed with the idea of assessing the capacity of a certain product to prevent the passage of caffeine across the biomimetic membrane with respect to a negative and positive control. The untreated membrane was the negative control, while membrane covered with a Vaseline film was the positive. As a last step, the developed barrier effect protocol was applied to an experimental gel-like SB-MD under development for the treatment of aphthae (Aphthae gel, an invented trade name), herein used as a case study. Regarding the results, Aphthae gel reduced the caffeine passage by 60.3%, thus highlighting its effectiveness to form a protective film. Overall, these results provide important knowledge and may pave the way for the use—including for industrial applications—of these simple but effective biomimetic membranes for carrying out high throughput screening necessary to design safe and effective SB-MDs before proceeding further with clinical trials, as requested by the regulations.

OXIDATIVE stress , *MALE infertility , *APOPTOSIS , *CAPSAICIN , *INFLAMMATION - Abstract
Recent research in rodents suggests that oxidative stress, inflammation, and apoptosis in the testes caused by high-fat diets (HFD) are a cause of male infertility. To investigate the therapeutic efficacy of the combination of hydroxycitric acid and capsaicin (HCC) against male reproductive disorders, we developed an HFD-induced obese rat model. Rats received HFD supplementation for 21 weeks, which induced obesity. From week 16, HCC (100 mg/kg body weight) was administered to investigate its potential to treat testicular toxicity. According to the results of the current study, treatment of obese rats with HCC improved their sperm quality, increased the production of testosterone, follicle-stimulating hormone, and luteinizing hormone and significantly increased the activities of steroidogenic enzymes and corresponding mRNA levels. In addition, HCC decreased lipid peroxidation and nitric oxide levels in both spermatozoa and testes while increasing the expression of mRNA for the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase in the testes, which in turn reduced oxidative stress in the testes. Moreover, after HCC treatment, testicular tissues showed a remarkable decrease in mRNA levels responsible for inflammation (TNF-α, IL-6, NF-κB) and apoptosis (Bax and Bcl-2). Our results suggest that HCC may alleviate obesity-induced male reproductive dysfunction by attenuating oxidative stress, inflammation, and apoptosis in the testes of HFD-induced obese male rats.

Despite the number of nutritional and medicinal plant‐based products that have been studied for decades, there are still many rare and underutilized plants of biological importance, whose nutritional and biochemical properties are unmatched, especially the wild doum palm, Hyphaene thebaica. Therefore, it is necessary to unveil the potential advantages of the wild fruit Hyphaene thebaica. The edible wild palm fruit is a rich source of novel nutraceutical and pharmaceutical constituents. It is a rare, underutilized but highly nutritious fruit found in the tropics, and it is rich in a variety of time‐proven healthy macro‐ and micronutrients. In addition to its domestic uses, it has a variety of significant healing potentials such as antioxidant properties, antihypertensive properties, hypolipidemic properties, antidiabetic properties, antimicrobial properties, cytotoxic/anticancer properties, hypolipidemic and neuroprotective properties, anti‐inflammatory properties, and hepatoprotective properties, among others. We hereby present a review of this multifunctional palm fruit, a rare and highly potent edible palm fruit with a broad spectrum of biochemical, domestic, nutraceutical, and pharmacological properties, which makes it a rare gem in the class of plant‐based functional food products. Much research and more clinical trials are necessary to further ascertain the veracity of the reported bioactivities through isolation, purification, and identification of the bioactive compounds. The multipurpose nature of the plant necessitates more research on its utilization in the fulfilment of various aspects of the United Nation's Sustainable Development Goals. [ABSTRACT FROM AUTHOR]

- Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a chronic liver disease. The development of MASLD is influenced by a multitude of diseases associated with modern lifestyles, including but not limited to diabetes mellitus, hypertension, hyperlipidaemia and obesity. These conditions are often consequences of the adoption of unhealthy habits, namely a sedentary lifestyle, a lack of physical activity, poor dietary choices and excessive alcohol consumption. The treatment of MASLD is primarily based on modifying the patient's lifestyle and pharmacological intervention. Despite the absence of FDA-approved pharmacological agents for the treatment of MASLD, several potential therapeutic modalities have demonstrated efficacy in reversing the histopathological features of the disease. Among the botanical ingredients belonging to the flavonoid group is quercetin (QE). QE has been demonstrated to possess a number of beneficial physiological effects, including anti-inflammatory, anticancer and antifungal properties. Additionally, it functions as a natural antioxidant. Preclinical evidence indicates that QE may play a beneficial role in reducing liver damage and improving metabolic health. Early human studies also suggest that QE may be an effective treatment for MASLD due to its antioxidant, anti-inflammatory, and lipid-regulating properties. This review aims to summarize the available information on the therapeutic effects of QE in MASLD. [ABSTRACT FROM AUTHOR]

Fetal undernutrition establishes the foundations for hypertension development, with oxidative stress being a key hallmark. A growing interest in nutraceuticals for treating hypertension and environmental waste concerns prompted the present study aiming to evaluate whether supplementation with a polyphenol enriched extract from cocoa shell (CSE), a by‐product from the chocolate industry with antioxidant properties, reduces hypertension of developmental origin, thus improving mesenteric resistance artery (MRA) vasodilatation. Adult male and female offspring from rats exposed to 50% food restriction from mid‐gestation (maternal undernutrition, MUN) and controls were used. Supplementation was given through a gelatine (vehicle, VEH) or containing CSE (250 mg kg−1 day−1) 5 days week−1 for 3 weeks. Systolic blood pressure (SBP) was assessed by tail‐cuff plethysmography. MRA function was studied by wire myography, and superoxide anion and nitric oxide were investigated by fluorescent indicators and confocal microscopy. Compared to control‐VEH, MUN‐VEH males showed significantly higher SBP, reduced MRA as well as relaxation to ACh, sodium nitroprusside and the AMPK agonist 5‐aminoimidazole‐4‐carboxamide riboside, but not to isoproterenol. In MUN males, endothelial endothelium‐derived hyperpolarizing factor and nitric oxide were unaltered, but MRA released a vasoconstrictor prostanoid and produced higher levels of superoxide anion. CSE normalized blood pressure and improved all above‐mentioned MRA alterations in MUN males without an effect on control counterparts, except the reduction of superoxide anion. MUN‐VEH females were normotensive and only showed a tendency towards larger superoxide anion production, which was abolished by CSE. CSE supplementation reduces SBP improving endothelium‐dependent and independent MRA vasodilatation, related to local superoxide anion reduction, being a potential nutraceutical ingredient to counteract hypertension, in addition to contributing to the circular economy. Key points: Fetal undernutrition induces hypertension in males associated with deficient resistance artery vasodilatation, being normalized by cocoa shell extract (CSE).Release of a cyclooxygenase‐derived contractile factor is the main endothelial alteration, which is abolished by CSE.AMPK and soluble guanylyl cyclase‐mediated relaxation are also reduced in smooth muscle cells from maternal undernutrition resistance arteries, being improved by CSE.Vascular oxidative damage caused by excess superoxide anion generation can account for impaired vasodilatation, which is improved by CSE.The capacity of CSE to improve relaxation is probably related to its antioxidant bioactive factors, and thus cocoa shell is a potential food by‐product to treat hypertension.

Introduction: Nutraceuticals are food-derived products offering supplementary health benefits. These nutraceuticals have been found effective in the treatment of the Parkinson's disease (PD) as they possess multifaceted effects against neurodegeneration. Nutraceuticals have proven their safety and efficacy in several pre-clinical and clinical trials against PD, however, still there is an urgent need to report the health benefits of nutraceuticals on a broader platform and evaluate their complete molecular mechanism against PD. Area covered: The review emphasizes the role of nutraceuticals in combating pathogenic mechanisms associated with PD. These include, mitochondrial dysfunction, protein ubiquitination, oxidative stress, excitotoxicity, neurotransmitter imbalance, neuroinflammation, inhibition of PPAR-ϒ/PGC-1α/NRF-2, and PON2 signaling pathways. The review also includes pre-clinical and clinical aspects of nutraceuticals in balancing the impaired gut-brain axis in PD. Expert opinion: In recent years there have been many reports on neuroprotective potential of PD. The growing interest showed that various supplements, including polyphenols, vitamins, minerals, and the Mediterranean diet, can aid promising therapeutic properties for relieving PD symptoms. However, at present, there is no specific nutraceutical that has been designed to treat the symptoms of PD. Future studies on nutraceuticals may focus on developing individualized as well as customized therapies using specialized nutraceuticals based on epigenetics and the expression of PD.

- Abstract
Gladiolus (Gladiolus grandiflora Hort.) is one of the important horticultural crops belonging to Iridaceae family. It grows in flowerbeds, borders, and containers and has immense potential as cut flowers. In this study, we have optimized the anthocyanin extraction from gladiolus Pusa Suahagin (PS) flower using one-variable-at-a-time (OVAT) and response surface methodology (RSM) methods. The optimum conditions for maximum anthocyanin content of 40.45 g
−1 DW was obtained considering the water:hydrochloride (1.8:0.6) ratio, temperature: 52.72 °C, time: 2 h and solid loading: 7% (w/v). MS studies confirmed the presence of pelargonidin, cyanidin, delphinidin, peonidin, petunidin, and malvidin compounds in PS flower extract. Free radical scavenging capability determined by DPPH assay of PS flower extract showed 84.63%, which implies that the PS flower extract can be used as colorant or nutraceutical in food industry and potential agent for enhancement of vase life pertinent to cut flowers in flower industry.

OLIVE oil industry , *FREE fatty acids , *PHARMACEUTICAL industry , *ANTIOXIDANT analysis , *BIOCHEMICAL substrates - Abstract
Hydroxytyrosol (HT) is a nutraceutical compound, mainly found in the fruit, leaves and waste from the olive oil industry, known for exhibiting one of the highest antioxidant activities among molecules of natural origin. To harness this bioactivity in cosmetics, pharmaceuticals and the food industry, it is essential to modify the hydrophilicity of HT to enhance its compatibility with lipid-based mixtures. This chemical modification must be carried out with high selectivity to avoid compromising its radical scavenging activity. This work presents a highly efficient and selective approach to perform the biocatalytic esterification of free fatty acids (FFAs) of different alkyl chain lengths with HT in a reaction medium based on the SLIL [C12mim][NTf2]. By using a 1:2 (mol/mol) HT:FFA mixture of substrates, the HT-monoester derivative was obtained up to 77% yield after 2 h at 80 °C. The optimized molar ratio of substrates, combined with the ability to recover the SLIL for further reuse, significantly reduces waste accumulation compared to other reported strategies and results in a more sustainable approach as demonstrated by different green metrics. The antioxidant activity of HT-monoester products was fully maintained with respect to that presented by the natural HT, being stable for at least 3 months at 4 °C, as demonstrated by the DPPH and FRAP antioxidant analysis.

- Abstract
With the rapid advancements in nutrition and dietary management, infant formulas for special medical purposes (IFSMPs) have been developed to cater to the unique nutraceutical requirements of infants with specific medical conditions or physiological features. However, there are various challenges in effectively preserving and maximizing the health benefits of the specific nutraceuticals incorporated in IFSMPs. This review provides an overview of the nutritional compositions of various IFSMPs and highlights the challenges associated with the effective supplementation of specific nutraceuticals for infants. In addition, it emphasizes the promising potential of emulsion delivery systems, which possess both encapsulation and delivery features, to significantly improve the solubility, stability, oral acceptance, and bioavailability (BA) of nutraceutical bioactives. Based on this information, this work proposes detailed strategies for designing and developing model IFSMP emulsions to enhance the BA of specially required nutraceuticals. Key areas covered include emulsion stabilization, selective release mechanisms, and effective absorption of nutraceuticals. By following these proposals, researchers and industry professionals can design and optimize emulsion‐based IFSMPs with enhanced health benefits. This review not only outlines the developmental states of IFSMP formulations but also identifies future research directions aimed at improving the physiological health benefits of IFSMPs. This effort lays the theoretical groundwork for the further development of emulsion‐type IFSMP in infant formula (IF) industry, positioning the IF industry to better meet the complex needs of infants requiring specialized nutrition.

- Abstract
Background/Objectives: Metabolic disorders, including diabetes, obesity, and cardiovascular diseases, are significant global health issues. Nutraceuticals, such as Sclerocarya birrea (SB), known for its high polyphenol content, are increasingly explored for managing these conditions. This study aims to evaluate the antihyperglycemic, hypolipidemic, and antihypertensive effects of SB in animal models to understand its potential as a natural intervention for metabolic diseases. Methods: A systematic review and meta-analysis were conducted according to PRISMA guidelines. Searches across databases like PubMed, Web of Science, Embase, and Scopus identified studies using SB in animal models of metabolic disorders. Inclusion criteria were studies with SB intervention, control groups, and quantitative measures of metabolic parameters. The study was registered with INPLASY (INPLASY2024100031). Results: The meta-analysis revealed that SB significantly reduces blood glucose levels in diabetic animal models. Acute administration of SB showed a pooled standardized mean difference (SMD) of −7.13 (95% CI: −11.44 to −2.83) at 1 h and −9.75 (95% CI: −15.92 to −3.59) at 2–4 h post-administration. Chronic administration indicated a non-significant reduction in glucose levels (SMD: −5.69, 95% CI: −16.38 to 5.01). Conclusions: SB appears to have the potential for reducing blood glucose levels and may offer benefits for other cardiometabolic risk factors, including lipid profiles and oxidative stress. However, variability in the results underscores the need for further research, including standardized animal studies and clinical trials, to confirm these effects and clarify the mechanisms by which SB may impact metabolic disorders.

- Abstract
Background/Objectives: The inflammatory response has evolved as a protective mechanism against pathogens and tissue damage. However, chronic inflammation can occur, potentially leading to severe disease. Low-grade chronic inflammation is associated with obesity, and the Th1 cytokine profile plays an important role in this proinflammatory environment. Diet-induced obesity (DIO) can lead to persistent dysbiosis and maintain high concentrations of circulating lipopolysaccharides (LPSs) over prolonged periods of time, resulting in metabolic endotoxemia. In this context, the study of natural immunomodulators has recently increased. Objective: The aim of this study is improve scientific evidence for the immunomodulatory role of L-Alliin in obesity and inflammation. Methods: In the present work, we describe the effect of L-Alliin on serum levels of cytokines in DIO mice after an acute inflammatory challenge. L-Alliin is the main organosulfurized molecule of garlic that has been studied for its numerous beneficial physiological effects in health and disease and is beginning to be considered a nutraceutical. Two situations are simulated in this experimental model, health and chronic, low-grade inflammation that occurs in obesity, both of which are confronted with an acute, inflammation-inducing challenge. Results: Based on our findings, L-Alliin seems to somehow stimulate the cellular chemotaxis by eliciting the release of key molecules, including IL-2, IFN-γ, TNF-α, MCP-1, IL-6, IL-9, and G-CSF. However, the molecular mechanism involved remains unknown. This, in turn, mitigates the risk of severe inflammatory symptoms by preventing the release of IL-1β and its downstream molecules such as IL-1α, GM-CSF, and RANTES. Conclusions: Taken together, these results indicate that L-Alliin can boost immunity in healthy organisms and act as an immunomodulator in low-grade inflammation. [ABSTRACT FROM AUTHOR]

Playford, Raymond John
- Abstract
Natural-based products are of interest to the pharmaceutical industry as potential sources of novel medicinal compounds. They are also used by consumers/patients as standalone therapies or as an adjunct to Western medicines. Two natural-based products of interest are chicken egg and bovine colostrum (the milk produced in the first few days following calving). Both products are rich in immunoglobulins, antimicrobial peptides, growth factors, and macro- and micro-nutrients. In vitro, in vivo, and a limited number of clinical studies suggest therapeutic benefits of both components given alone and together. Combination therapy is of particular interest, as preclinical studies suggest synergistic effects on growth, repair, and gut protection, including microbiome-induced damage. This article describes the main constituents of egg and bovine colostrum, studies of their use alone and together for a wide range of conditions, highlights areas requiring further research, and describes novel indications such as GLP-1-associated gut symptoms. While well placed in the food supplement arena, additional high-quality clinical trials are required to establish their benefits in clinical practice. [ABSTRACT FROM AUTHOR]

- Abstract
Background/Objectives: Studies have shown that consistent reductions of 2 mm Hg in systolic blood pressure (SBP) for the general normotensive population can result in significant decreases in mortality from heart disease and stroke. The purpose of this meta-analysis was to determine the optimal dose and duration of treatment for magnesium and potassium supplementation, having previously discovered that both reduce SBP by −2.79 and −2.10 mm Hg, respectively. Methods: Placebo-controlled, randomized clinical trials examining the effects of magnesium and potassium supplementation on SBP were identified. Pairwise meta-analyses with subgroups for dosage and treatment duration were run. Results: Magnesium at dosages of ≤360 mg/day and durations greater than 3 months reduced SBP by −3.03 and −4.31 mm Hg, respectively. Potassium at dosages of ≤60 mmol/day and durations greater than 1 month reduced SBP by −2.34 and −2.80 mm Hg, respectively. Conclusions: Both supplements demonstrated greater reductions in SBP for the general population at lower dosages and longer treatment durations. Future studies are needed to validate these findings and provide tailored recommendations. These studies could investigate varying dosages over long-term follow-up to provide robust data on optimal dosages and treatment durations, as our findings were limited due to reliance on previously published trials.

- Abstract
Introduction: Microbiota, composed of micro-organisms like bacteria, viruses, and non-pathogenic fungi, plays a crucial role in digestion, vitamin production, and protection against dangerous microbes. Several factors, including age, diet, alcohol consumption, stress, environmental microorganisms, and therapies (particularly antibiotics), as well as birth and nursing, could modify the microbiota. Recent research has highlighted its alteration and involvement in a various disease, including metabolic syndrome and acne. This systematic review aimed to identify common biomarkers and microbiota alterations shared between metabolic syndrome and acne, and to explore how the potential prebiotic activities of polyphenols may promote intestinal eubiosis. Materials and methods: A comprehensive search in PubMed and EMBASE resulted in 4142 articles, from which nine studies were selected based on specific criteria after removing duplicates and reviewing abstracts and full texts. All studies correlated the microbiota alteration in both pathologies and the activity of polyphenols in metabolic syndrome. Results: This review suggests that acne may be influenced by some of the same microorganisms involved in metabolic syndrome. While the literature highlights the effectiveness of polyphenols in treating metabolic syndrome, no studies have yet demonstrated their specific impact on acne. Conclusions: The research points to the potential benefits of polyphenols in modulating the microbiota, which could be relevant for individuals with metabolic syndrome. However, due to the limited data available, it was not possible to establish a direct correlation between metabolic syndrome and acne. [ABSTRACT FROM AUTHOR]

The diversified use of natural products from annually regenerating tissues from tropical tree taxa may contribute to biodiversity conservation through sustainable use. In this review, we compiled food and medicinal properties and uses of the megadiverse Brazilian Myrtaceae, reported in 95 scientific articles, 5 reference books, 2 online databases, and 1 practitioner source. Among the 551 species assessed for conservation status, we found food or medicinal uses in 187, a third of which are under some degree of threat of extinction. We provide a comprehensive summary of their reported properties for food (168 species) and medicine (42 species). Fruits, leaf essential oil, and plant extracts are the main products researched. A total of 44 fruit species were found with some risk of extinction status, especially red-purple and yellow-orange-colored fruits, but only 10 species have been scientifically studied. Research related to the medicinal properties of Myrtaceae species has been performed mainly for essential oils and plant extracts. The species Campomanesia phaea, Pimenta pseudocaryophyllus, Plinia edulis, and Eugenia mattosii stand out regarding their scientifically proven medicinal use. These products have a set of nutritional components and/or bioactive compounds that can supply specific demands from the food, pharmaceutical and/or cosmetic industries. The outstanding suitability for sustainable planting and continuous harvesting of Myrtaceae fruits and leaves provides a thus-far neglected opportunity for conservation through sustainable use of their natural products.

- Abstract
Liver diseases emerge as a serious threat to humans worldwide due to increasing morbidity and mortality. Liver disease related deaths accounts for one third of all disease related death globally. A simple fatty liver if unattended advances further to liver fibrosis, cirrhosis and hepatocellular carcinoma. During liver fibrogenesis, hepatic stellate cells gets activated into myofibroblast like cells and exhibit proliferative and fibrogenic features. Targeting these activated hepatic stellate cells offer promising therapeutic approach towards liver fibrosis management. To date there is no Food and Drug Administration approved treatments for liver fibrosis. However, a large number of clinical trials are being conducted employing monoclonal antibodies, drugs, dietary supplements and herbal medicines. A vast number of research findings demonstrated nutraceuticals to be effective against experimental liver fibrosis both in vitro and in vivo. Nutraceuticals typically regulate key signaling pathways in activated hepatic stellate cells and exhibit anti-fibrotic effect. In this review, the mechanistic action of nutraceuticals targeting activated hepatic stellate cells were summarized to establish them as a possible therapeutic candidate for liver fibrosis.

A new subclass of nutraceuticals, called immunoceuticals, is dedicated to immunological regulation. Although yeast-derived β-1,3/1,6-D-glucan shows promise as an immunoceutical candidate, further studies are needed to define its precise immune-enhancing processes and to standardize its use. Following methotrexate (MTX)-induced immunosuppression in rats, we evaluated the immunomodulatory efficacy of a highly pure and standardized β-1,3/1,6-D-glucan sample (YBG) in RAW 264.7 macrophages. In in vitro and in vivo models, YBG demonstrated remarkable immunomodulatory effects, such as repair of immune organ damage, elevation of blood cytokine levels, and enhanced phagocytosis and nitric oxide production in RAW 264.7 cells. These results are consistent with the established immunostimulatory properties of β-glucan. It is noteworthy that this research indicates the potential of YBG as an immunomodulatory nutraceutical, as it is among the first to demonstrate immunological augmentation in an immunosuppression setting produced by MTX. Based on these observations, further investigation of YBG is warranted, particularly given its potential to emerge as a combination immunoceutical to mitigate immunosuppression and reduce the risk of infection in rheumatoid arthritis (RA) patients receiving long-term MTX therapy.

Multiple sclerosis (MS) is an immune-mediated disease characterized by inflammation, demyelination, and neurodegeneration within the central nervous system. Brain plasticity, the brain's ability to adapt its structure and function, plays a crucial role in mitigating MS's impact. This paper explores the potential benefits of lifestyle changes and nutraceuticals on brain plasticity in the MS population. Lifestyle modifications, including physical activity and dietary adjustments, can enhance brain plasticity by upregulating neurotrophic factors, promoting synaptogenesis, and reducing oxidative stress. Nutraceuticals, such as vitamin D, omega-3 fatty acids, and antioxidants like alpha lipoic acid, have shown promise in supporting brain health through anti-inflammatory and neuroprotective mechanisms. Regular physical activity has been linked to increased levels of brain-derived neurotrophic factor and improved cognitive function. Dietary interventions, including caloric restriction and the intake of polyphenols, can also positively influence brain plasticity. Integrating these lifestyle changes and nutraceuticals into the management of MS can provide a complementary approach to traditional therapies, potentially improving neurological outcomes and enhancing the quality of life for the MS population.

Background: Fenugreek, or Trigonella foenum greacum, is an ancient medicinal plant native to the eastern Mediterranean that later spread to Asia; it is used as a medicinal herb, spice, or food. It is a component of spice mixes, such as curry, and it is also used as a supplement in wheat and corn flour for bread making. Fenugreek appears to have many health benefits and potential medicinal properties; for this reason, it is increasingly being used in nutraceutical formulations. This study aimed to describe patients who visited our operative unit for a suspected adverse reaction after ingestion of fenugreek and to highlight possible cross-reactivity between fenugreek and other legumes or other foods. Methods: A total of 13 patients (5 males and 8 females; mean age: 30.6; range: 20–42 years) visited our outpatient clinic with a clinical history suggestive of an allergic reaction to spices or legumes. They underwent a skin prick test for fenugreek, fresh foods, and food extracts. Results: A total of 6 out of 13 patients positive for fenugreek had experienced allergic symptoms after ingesting foods containing spices, and 10 patients presented polysensitization with other legumes, of which 8 also presented sensitization to pistachios. Conclusions: Given the increasing use of novel spices in Mediterranean cuisine and the possible spread of fenugreek-based nutraceuticals, it is relevant to draw attention to possible allergic reactions. Further studies are also needed to be able to establish its cross-reactivity pattern. [ABSTRACT FROM AUTHOR]

This study analysed the phytochemical profile of Acmella oleracea extract and the molecular interactions of its main compounds with TRPV1 and CB2, target receptors in the Burning Mouth Syndrome (BMS) pathogenesis. The phytochemical profile of A. oleracea's floral buds extract treated with activated charcoal (TCEE) was analysed by High-Performance Liquid Chromatography (HPLC) coupled to Mass Spectrometry (LC-MS). The quantification of spilanthol was analysed by HPLC coupled to a Diode-Array Detector (HPLC-DAD). The phytochemical analysis revealed the presence of nine alkylamides and phenolic compounds. The TCEE showed a significant increase in spilanthol content compared to the crude extract (CEE), going from 28.33 mg/g to 117.96 mg/g. The molecular docking indicated a behaviour of the alkylamides as partial TRPV1 agonists and CB2 agonists and, for the first time, indicates the action of these compounds in the symptomatic management of BMS.

Tea is the second most widely consumed beverage globally, after water, and is known for its substantial antioxidant properties, primarily due to its phenolic content. This study quantifies phenolic compounds and assesses antioxidant activity in ten types of tea and selected herbal infusions, individually and in combination. Our findings reveal that free phenolic compounds and their antioxidant activity were twelve times and eight times greater than bound phenolic compounds. Among individual infusions, white tea exhibited the highest antioxidant activity and phenolic content, with 172.51 µmol TE/1000 g and 7.83 mg GAE/1000 g, respectively. In combination, white/linden flower tea showed the highest antioxidant activity (374.44 µmol TE/1000 g), and white/orange tea contained the highest phenolic content (9.24 mg GAE/1000 g). This study identified primarily two phenolic compounds, epigallocatechin gallate and epicatechin gallate, and one alkaloid, caffeine, in tea and herbal combinations. Compared to other combinations, we observed significant variations in catechins and caffeine between white and dark teas. Integrating specific herbal infusions with tea can enhance antioxidant activity up to three-fold compared to tea alone. This research offers valuable insights into optimizing herbal infusions to maximize antioxidant benefits, creating new opportunities to enhance the health benefits of tea-based products.

Over the past decade, several studies have established a direct link between functional foods, nutraceuticals, and a reduced risk of oxidative-stress-related diseases. Nutraceuticals, which encompass a variety of bioactive molecules, exhibit both nutritional and therapeutic properties. The cactus pear (Opuntia spp.) is a plant genus with many species recognized as functional foods, largely attributed to their high content of nutraceuticals, including polyphenols, fatty acids, vitamins, amino acids, pigments, and phytosterols. These compounds of different structures and functions possess different biological activities, contributing to the health-promoting properties of cactus pear. This makes cactus pears a valuable plant for the food, cosmetic, and pharmaceutical industries. While extensive research has focused on the nutritional profile of cactus pear fruits, the cladodes have received comparatively limited attention. Notably, the nutritional composition of cladodes can exhibit considerable variability, influenced by species and growing conditions. Furthermore, although various bioactive compounds have been identified in cladodes, studies elucidating their mechanisms of action, health benefits, and potential therapeutic applications remain insufficient. Addressing these gaps is crucial for enhancing the understanding and utilization of cactus pear cladodes. This paper provides a comprehensive overview of the structure–function relationships of the main nutraceuticals found in cactus pear cladodes. It synthesizes data from recent and relevant literature to elucidate the content of these compounds in relation to species and geographical origin, while also detailing the main biological activities and health-promoting benefits associated with cactus pear cladodes.

Xylooligosaccharides (XOS) are considered a potent source of prebiotics for humans. The global prebiotic market is expanding in size, was valued at USD 6.05 billion in 2021, and is expected to grow at a 14.9% compound annual growth rate between 2022 and 2030, indicating a huge demand. These XOS are non‐digestible pentose sugar oligomers comprising mainly xylose. Xylose is naturally present in the lignocellulosic biomass (LCB), fruits and vegetables. Apart from the prebiotic effect, these XOS have been reported to reduce blood cholesterol, possess antioxidant effects, increase calcium absorption, reduce colon cancer risk, and benefit diabetic patients. The primary use of XOS is reported in the feed industry followed by health, medical use, food and drinks. LCB mainly contains glucan, xylan and lignin. After glucan, xylan is the second‐highest available sugar on the globe composed of xylose. Therefore, the xylan fraction of LCB has great significance in producing food, feed and energy. Glucan has been exploited for the commercial production of ethanol, xylitol, furfural, hydroxymethyl furfural and glucose. As of now, xylan has limited applications. Therefore, xylan can be exploited to convert to XOS. The production of XOS from LCB fraction not only helps to produce these at a very low price, but also helps in the reduction of greenhouse gases. Its use in food and drinks is increasing as it can be derived from the abundantly and cheaply available LCB. The article provides a review on the production, purification and characterization of XOS in view of their use as nutraceuticals. © 2024 The Authors.

Background: Omega‐3 fatty acids (ω‐3 FA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), are essential nutrients known for their anti‐inflammatory properties, which involve reducing pro‐inflammatory cytokines, eicosanoids, and insulin‐like growth factor‐1. This suggests their potential to alleviate acne severity, especially when deficits are present. Aims: To elevate EPA/DHA levels in acne patients through dietary intervention and supplementation, observing subsequent clinical effects. Methods: Over 16 weeks, 60 patients without prescription medication (n = 23 acne comedonica [AC], n = 37 acne papulopustulosa [AP]) adhered to a Mediterranean diet, incorporating oral algae‐derived ω‐3 FA supplementation (600 mg DHA/300 mg EPA week 1–8, 800 mg DHA/400 mg EPA week 8–16). At four visits (V1–V4), blood EPA/DHA levels were tracked using the HS‐omega 3 index® (EPA/DHA (%) of total identified fatty acids in erythrocytes; target 8%–11%, deficit <8%, severe deficit <4%), alongside clinical assessments and standardized questionnaires. Results: At baseline, 98.3% of patients had an EPA/DHA deficit, with the mean HS‐omega 3 index® rising from 4.9% at V1 to 8.3% at V4 (p < 0.001). AC showed significantly higher indices than AP at V4 (p = 0.035). Objective improvements in both inflammatory and non‐inflammatory lesions were observed (p < 0.001). While self‐reported appearance worsened in four patients, overall quality of life improved (p < 0.001), particularly in AP. Dietary triggers were more clearly defined than beneficial foods. Intake of cow's milk and dairy products reduced (p < 0.001). Compliance was good; no adverse events were reported. Conclusion: Many acne patients have a ω‐3 FA deficit. The HS‐omega 3 index® can be increased by a Mediterranean diet and oral supplementation with algae‐derived ω‐3 FA. Acne severity improved significantly in patients with target ω‐3 FA levels.

27. Amelioration of Phytanic Acid–Induced Neurotoxicity by Nutraceuticals: Mechanistic Insights.

- Abstract
Phytanic acid (PA) (3,7,11,15-tetramethylhexadecanoic acid) is a methyl-branched fatty acid that enters the body through food consumption, primarily through red meat, dairy products, and fatty marine foods. The metabolic byproduct of phytol is PA, which is then oxidized by the ruminal microbiota and some marine species. The first methyl group at the 3-position prevents the β-oxidation of branched-chain fatty acid (BCFA). Instead, α-oxidation of PA results in the production of pristanic acid (2,10,14-tetramethylpentadecanoic acid) with CO
2 . This fatty acid (FA) builds up in individuals with certain peroxisomal disorders and is historically linked to neurological impairment. It also causes oxidative stress in synaptosomes, as demonstrated by an increase in the production of reactive oxygen species (ROS), which is a sign of oxidative stress. This review concludes that the nutraceuticals (melatonin, piperine, quercetin, curcumin, resveratrol, epigallocatechin-3-gallate (EGCG), coenzyme Q10, ω-3 FA) can reduce oxidative stress and enhanced the activity of mitochondria. Furthermore, the use of nutraceuticals completely reversed the neurotoxic effects of PA on NO level and membrane potential. Additionally, the review further emphasizes the urgent need for more research into dairy-derived BCFAs and their impact on human health. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Breast cancer (BC) represents the most prevalent cancer in women at any age after puberty. From a pathogenetic prospective, despite a wide array of risk factors being identified thus far, poor metabolic health is emerging as a putative risk factor for BC. In particular, type 2 diabetes mellitus (T2DM) provides a perfect example bridging the gap between poor metabolic health and BC risk. Indeed, T2DM is preceded by a status of hyperinsulinemia and is characterised by hyperglycaemia, with both factors representing potential contributors to BC onset and progression. Additionally, the aberrant secretome of the dysfunctional, hypertrophic adipocytes, typical of obesity, characterised by pro-inflammatory mediators, is a shared pathogenetic factor between T2DM and BC. In this review, we provide an overview on the effects of hyperglycaemia and hyperinsulinemia, hallmarks of type 2 diabetes mellitus, on breast cancer risk, progression, treatment and prognosis. Furthermore, we dissect the role of the adipose-tissue-secreted adipokines as additional players in the pathogenesis of BC. Finally, we focus on microalgae as a novel superfood and a source of nutraceuticals able to mitigate BC risk by improving metabolic health and targeting cellular pathways, which are disrupted in the context of T2DM and obesity.

Given the increasing food needs of humanity and the challenges cultivated species face in adapting to the climatic uncertainties we experience, it is urgent to cultivate new species. A highly relevant repertoire for this purpose is offered by the array of edible wild plants. We analyzed data from Murcia (Spain), involving 61 species and 59 informants, and the Global Database of Wild Food Plants, which includes 15,000 species, 500 localities, and nearly 700 references. Using local consensus, global distribution, and GBIF occurrence data, we built simple unimodal or bimodal models to explore their limitations. Our study highlights that approximately 15,000 wild or feral plant species are consumed as food, underlining the urgent need to support existing crops with new species due to current food crises and climate irregularities. We examined wild plant diversity from a horticultural perspective, considering their relationships with weeds and invasive species. Partial criteria, such as local consensus or global use, were found insufficient for selecting candidate species. We propose developing a specific artificial intelligence to integrate various factors—ecological, nutritional, toxicological, agronomic, biogeographical, ethnobotanical, economic, and physiological—to accurately model a species' potential for domestication and cultivation. We propose the necessary tools and a protocol for developing this AI-based model. [ABSTRACT FROM AUTHOR]

- Abstract
Indian pennywort (Centella asiatica L.) is an emerging medicinal cum nutraceutical herb known for its neuroprotective properties. The antioxidant activity is an important parameter for its supposed benefits. Currently the genetic diversity of the crop remains underexploited and research related to genetic variability of antioxidant activity and its component traits is limited. This experiment was carried out to know the genetic variability in the nutraceutical compositions in 20 accessions collected from hill zone of Karnataka, India (with three checks viz., Arka Prabhavi, Arka Divya and Vallabh Medha). The results showed a wide variation among the accessions for mineral composition viz., phosphorus, potassium, calcium, iron and zinc; phytochemical constituents viz., total carotenoids, anthocyanin, total phenols, total flavonoids, tannins, oxalates, ascorbic acid and antioxidant activity. Most of the parameters such as iron, zinc, total carotenoids, anthocyanin, total phenols, oxalates and antioxidant activity showed higher genotypic and phenotypic coefficient of variability (GCV and PCV, respectively). All the parameters showed higher heritability and genetic advance. Total flavonoids, zinc and total phenols were ascertained to be the major contributors of antioxidant activity according to correlation and path analysis research. The grouping of the accessions based on Mahalanobis D
2 analysis resulted in five clusters. These suggests the wider genetic diversity among the accessions. Further, the traits are governed by additive gene action indicating that these characters could be considered for selection for further crop improvement for antioxidant activity.

While the potential of Asteraceae plants as herbal remedies has been globally recognized, their widespread application in the food, cosmetic, and pharmaceutical industries requires a deeper understanding of how extraction methods influence bioactive compound yields and functionalities. Previous research has primarily focused on the physiological activities or chemical compositions of individual Asteraceae species, often overlooking the critical role of solvent selection in optimizing extraction. Additionally, the remarkable physiological activities observed in these plants have spurred a growing number of clinical trials, aiming to validate their efficacy and safety for potential therapeutic and commercial applications. This work aims to bridge these knowledge gaps by providing an integrated analysis of extraction techniques, the diverse range of bioactive compounds present in Asteraceae, and the influence of solvent choice on isolating these valuable substances. By elucidating the interplay between extraction methods, solvent properties, and bioactivity, we underscore the promising potential of Asteraceae plants and highlight the importance of continued research, including clinical trials, to fully unlock their potential in the food, cosmetic, and pharmaceutical sectors.

In recent years, consumers have been increasingly interested in natural, healthier, functional foods, with a focus on sea-based products such as algae. Bifurcaria bifurcata (BB) is a macroalga that belongs to the Phaeophyceae class. These brown algae are recognized as the source of bioactive molecules of great interest to the pharmaceutical and nutraceutical industries. The present work applied response surface methodology to optimize the microwave-assisted extraction of the poorly studied algae. The optimization variables were time, pressure, and solvent composition (ethanol/water) and the response parameters selected were yield, total phenolic and flavonoid content, and the antioxidant profile by evaluating DPPH
•+ , ABTS•+ scavenging activity, and β-carotene discoloration capacity. The results obtained reveal remarkable bioactivity of the crude extract of BB with positive results as an antioxidant and antimicrobial agent. Furthermore, the BB extract's capacity to inhibit enzymes related to neurodegenerative diseases and its anti-inflammatory and anti-proliferation activity open the possibility of future food or pharmaceutical applications.

Abstract Rice (Oryza sativa L.) has been the dietary staple of Sri Lankans since ancient times. The native or indigenous varieties that were cultivated historically have evolved across generations, into the traditional varieties recognized today. These traditional varieties are known for their superior nutritional and health benefits compared to the improved varieties which were introduced to the country in the mid 19 s upon selective breeding and hybridization. Traditional rice has been used in ethnic and Ayurveda medicine as a direct medicinal, nutritional or dietary supplement to treat a vast number of ailments. In the past few decades, the nutra–pharmaceutical potential of traditional and improved Sri Lankan rice varieties has been extensively studied in-vitro. The health benefits of Sri Lankan rice include the presence of bioactive constituents that promote antioxidant defence, and antimicrobial, anti-inflammatory, and anticancer activities. This narrative review summarizes and evaluates the published scientific evidence for the last twenty-five years on nutra-phamacutical potential of Sri Lankan rice in-vitro, highlights the role of Sri Lankan rice in ethnic medicine, and discusses total nutra-phamaceutical content and associated health benefits in regard to; variety types, grain pericarp colours and post-harvest modifications such as milling, polishing and parboiling. The majority of studies demonstrate significantly higher levels of nutra-pharmaceutical potential in traditional over improved varieties, bran intact/ whole grains over polished rice, and red over white pericarp grains as well as the impact of agrochemical practices during cultivation.

Abstract Anti‐amyloidogenic properties of plant pigments betalains as potential nutraceuticals against Alzheimer's disease have been screened using 24 pure molecules. Twenty‐two betalains reduced amyloid aggregation in vitro, eight of them up to 100%, with IC50 values in the micromolar range. Atomic force and transmission electron microscopy images showed the typical fibrils associated with Alzheimer's disease and how betalains avoid its formation. Neuroprotection after ingestion was supported by in vivo experiments with Caenorhabditis elegans. Indoline‐betacyanin was the most effective molecule by significantly improving the chemotactic behavior of the CL2355 strain, a model of Alzheimer's disease. Furthermore, in‐depth molecular docking analyses revealed that the pigments interact with the N‐terminal region of the amyloid peptide. This work is the most comprehensive study in the field and provides in vitro, in vivo, and in silico evidence for the use of betalains as nutraceuticals of relevance in the prevention of Alzheimer's disease.

The olive tree is currently cultivated worldwide, with higher incidence in Mediterranean Basin. Its climate is highly favorable to the synthesis of phenolic compounds, stored in olive leaves; their consumption has been linked to a lower incidence of cancer and cardiovascular disorders for which the research interest upon this feature has increased in last decade. This study aimed (i) to review evidence about the importance of olive leaf extract (OLE) on human health and the physiological effect of its major compounds; (ii) to update the state of the art of studies conducted on the health and technological usage of olive leaf extract; (iii) to report potential uses of OLE in pharmaceuticals, food production, and cosmetics; and (iv) to prospect the future of clinical applications of OLE from diverse cultivars, especially in metabolic inflammatory conditions such as polycystic ovary syndrome (PCOS). Overall, cultivars richer in TPC, including TFC, αT, omega-3 and omega-9, present a main research target for supplementation alone or in conjunction with vitaminic compounds, due to their nutraceutical value in metabolic disorders, chronic inflammatory diseases, and anti-aging treatments, whereas cultivars with less water content might be useful as substrates for food preservation. With regard to future prospects, it would be of great interest to clarify the specific mechanisms underlying the beneficial effects of OLE on neuro-immune and cardiovascular health to design safer and healthier nature-based medicine for a wide array of costly and highly prevalent chronic diseases, such as inflammatory and metabolic-related syndromes, namely, PCOS.

Abstract Acute myeloid leukemia (AML) is a hematologic neoplasm, characterized by a blockage of differentiation and an unconstrained proliferation of immature myeloid cells. Recently, the survival of leukemia patients has increased thanks to the use of differentiating agents, though these may cause serious side effects. Hence, the search for safer differentiating compounds is necessary. Our aim was to assess the pro-differentiating effects of a flavonoid-rich extract of bergamot juice (BJe) in human monocytic leukemia THP-1 cells, an in vitro AML model. For the first time, we showed that treatment with BJe induced differentiation of THP-1 cells, changes in cell morphology and increased expression of differentiation-associated surface antigens CD68, CD11b and CD14. Moreover, BJe enhanced protein levels of autophagy-associated markers, such as Beclin-1 and LC3, as well as induced the phosphorylation of the MAPKs JNK, ERK and p38, hence suggesting a potential mechanism underlying its antiproliferative effects. Indeed, parallel experiments highlighted that BJe was able to hamper THP-1 cell growth. In conclusion, our study suggests that BJe induces the differentiation of THP-1 cells and reduces their proliferation, highlighting its potential in differentiation therapy of AML.

Abstract Antibiotics, improper food, and stress have created a dysbiotic state in the gut and almost 81% of the world’s population has been affected due to the pandemic of COVID-19 and the prevalence of dengue virus in the past few years. The main intent of this study is to synthesize nanosynbiotics as nu traceuticals by combining probiotics, and prebiotics with nanoformulation. The effectiveness of the nanosynbiotics was evaluated using a variety of Nutra-pharmacogenetic assays leading to an AI-integrated formulation profiling was assessed by using machine learning methods. Consequently, Acetobacter oryzoeni as a probiotic and inulin as a prebiotic has been chosen and iron-mediated nanoformulation of symbiotic is achieved. Nanosynbiotics possessed 89.4, 96.7, 93.57, 83.53, 88.53% potential powers of Nutra-pharmacogenetic assays. Artificial intelligent solid dispersion formulation of nanosynbiotics has high dissolution, absorption, distribution, and synergism, in addition, they are non-tox, non-allergen and have a docking score of − 10.83 kcal/mol, implying the best interaction with Pregnane X receptor involved in dysbiosis. The potential of nanosynbiotics to revolutionize treatment strategies through precise targeting and modulation of the gut microbiome for improved health outcomes and disease management is promising. Their transformational influence is projected to be powered by integration with modern technology and customized formulas. Further in-vivo studies are required for the validation of nanosynbiotics as nutraceuticals.

Summary: Age-related neurodegeneration is an important public health challenge with the increasing burden of geriatric disease in the aging world population. Interest in nutraceuticals in the prevention and management of age-related neurodegeneration is therefore becoming more important than ever, especially in the management of neurodegenerative diseases and mild cognitive impairments, which are major contributors to the burden of geriatric disease. Polyunsaturated fatty acids are considered one of the most important nutraceuticals with their biochemical mechanisms, especially antioxidant and anti-inflammatory. Potential mechanisms by which PUFAs alleviate or prevent neurodegeneration include suppression of neuroinflammation and neurotoxicity, neuro-recovery, and support of the blood-brain barrier integrity. This review will consider the mechanisms and current information on the effect of supplementation or dietary intake of polyunsaturated fatty acids as nutraceuticals on neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

Currently, a large number of people favor meals that are rich in nutraceuticals and phytochemical compounds, which help with the treatment or prevention of chronic diseases. Oral bioavailability is a crucial component of phytochemical bioefficiency, and endogenous mechanisms have a significant impact on how well nutraceuticals and phytochemicals are absorbed by the body. In addition to endogenous variables, exogenous factors that impact the bioavailability of bioactives include the food matrix, food processing, and food storage. Different delivery systems have evolved in this regard, and nanoscale delivery tools have also been created. Delivery methods that use nanostructured lipid carriers show benefits such as enhanced loading capacity, solubility, encapsulation effectiveness, storage stability, bioavailability, and half-life. They also provide safe food systems and regulated release. In this review, the outcomes of recent experimental reports are comprehensively reviewed. In addition, the food processing, storage, gut milieu circumstances, the release process from the food and nano delivery systems in the gastrointestinal tract (GIT) milieu, interactions with other GIT constituents, main delivery systems based on nanostructured lipid carriers for their encapsulation and eventually encapsulating technological barriers, food safety concerns, and regulatory issues of nutraceutical and phytochemical compounds are discussed.

Abstract Ulcerative colitis (UC) is a recurring autoimmune disorder characterized by persistent inflammation in the mucosal lining of the lower part of the large intestine. Conventional treatment options such as salicylates, corticosteroids, and immunosuppressants often come with severe side effects, limited bioavailability, and the development of drug resistance, which hampers their therapeutic effectiveness. Therefore, it is imperative to explore natural strategies as safe and alternative treatments for UC. Currently, around 40% of UC patients find relief through natural constituents, which can help reduce toxic side effects and maintain clinical remission. This review aims to provide a summary of both preclinical and clinical evidence supporting the efficacy of various natural substances in the prophylaxis of UC. These natural options include plant extracts, essential oils, nutraceuticals, and phytochemicals. Furthermore, we will delve into the potential mechanisms that underlie the protective and curative actions of these novel herbal agents. In summary, this review will explore the effectiveness of natural remedies for UC, shedding light on their preclinical and clinical findings and the mechanisms behind their therapeutic actions. These alternatives offer hope for improved treatment outcomes and reduced side effects for individuals suffering from this challenging autoimmune condition. Graphical Abstract

The onset of neurodegenerative diseases involves a complex interplay of pathological mechanisms, including protein aggregation, oxidative stress, and impaired autophagy. This review focuses on the intricate connection between oxidative stress and autophagy in neurodegenerative disorders, highlighting autophagy as pivotal in disease pathogenesis. Reactive oxygen species (ROS) play dual roles in cellular homeostasis and autophagy regulation, with disruptions of redox signaling contributing to neurodegeneration. The activation of the Nrf2 pathway represents a critical antioxidant mechanism, while autophagy maintains cellular homeostasis by degrading altered cell components. The interaction among p62/SQSTM1, Nrf2, and Keap1 forms a regulatory pathway essential for cellular stress response, whose dysregulation leads to impaired autophagy and aggregate accumulation. Targeting the Nrf2-p62/SQSTM1 pathway holds promise for therapeutic intervention, mitigating oxidative stress and preserving cellular functions. Additionally, this review explores the potential synergy between the endocannabinoid system and Nrf2 signaling for neuroprotection. Further research is needed to elucidate the involved molecular mechanisms and develop effective therapeutic strategies against neurodegeneration.

Abstract Medicinal mushrooms, such as Taiwanofungus camphoratus, Inonotus obliquus, and Tropicoporus linteus, have been used in traditional medicine for therapeutic purposes and promotion of overall health in China and many East Asian countries for centuries. Modern pharmacological studies have demonstrated the large amounts of bioactive constituents (such as polysaccharides, triterpenoids, and phenolic compounds) available in these medicinal mushrooms and their potential therapeutic properties. Due to the rising demand for the health-promoting medicinal mushrooms, various cultivation methods have been explored to combat over-harvesting of the fungi. Evidence of the robust pharmacological properties, including their anticancer, hypoglycemic, hypolipidemic, antioxidant, and antiviral activities, have been provided in various studies, where the health-benefiting properties of the medicinal fungi have been further proven through numerous clinical trials. In this review, the cultivation methods, available bioactive constituents, therapeutic properties, and potential uses of T. camphoratus, I. obliquus and T. linteus are explored.

BACKGROUND RESULTS CONCLUSION Obesity is a non‐communicable complex disease that is the fifth leading cause of death worldwide. According to a novel viewpoint, the brain plays a significant role in the central regulation of satiety and energy homeostasis. Because of its rich nutritional profile and versatile uses, oat (Avena sativa) is one of the most popular functional foods recommended by many nutritionists. The anti‐obesity effect of oat was hypothesized, focusing on the brain as the target organ. In the current study, the interplay between brain biomarkers, obesity, and its related complications was evaluated in diet‐induced obese rats for 25 weeks, in which 60 adult male white albino Wistar rats were divided into three control and seven treatment groups given oat extracts in a dose‐dependent manner.Oat significantly improved obesity‐related metabolic complications. In terms of brain function, oat significantly increased dopaminergic signaling, brain‐derived neurotrophic factor levels, vaspin, irisin, and uncoupling protein‐1 brain levels, while decreasing the expression of agouti‐related peptide and neuropeptide Y (P‐value < 0.05).The current study proposes oat supplementation as a new conceptual framework with numerous implications for hedonic and homeostatic mechanisms that control satiety. © 2024 Society of Chemical Industry.

DURIAN , *PLANT proteins , *PROTEIN domains , *EDIBLE plants , *CALCIUM-binding proteins - Abstract
The protein S100B is a part of the S100 protein family, which consists of at least 25 calcium-binding proteins. S100B is highly conserved across different species, supporting important biological functions. The protein was shown to play a role in gut microbiota eubiosis and is secreted in human breast milk, suggesting a physiological trophic function in newborn development. This study explores the possible presence of the S100B motif in plant genomes, and of S100B-like immunoreactive material in different plant extracts, opening up potential botanical uses for dietary supplementation. To explore the presence of the S100B motif in plants, a bioinformatic workflow was used. In addition, the immunoreactivity of S100B from vegetable and fruit samples was tested using an ELISA assay. The S100B motif was expected in silico in the genome of different edible plants belonging to the Viridiplantae clade, such as Durio zibethinus or Malus domestica and other medicinal species. S100B-like immunoreactive material was also detected in samples from fruits or leaves. The finding of S100B-like molecules in plants sheds new light on their role in phylogenesis and in the food chain. This study lays the foundation to elucidate the possible beneficial effects of plants or derivatives containing the S100B-like principle and their potential use in nutraceuticals.

Atherosclerosis (AS) is a chronic inflammatory vascular disease. Dysregulated lipid metabolism, oxidative stress, and inflammation are the major mechanisms implicated in the development of AS. In addition, evidence suggests that gut dysbiosis plays an important role in atherogenesis, and modulation of the gut microbiota with probiotics and phenolic compounds has emerged as a promising strategy for preventing and treating AS. It has been shown that probiotics and phenolic compounds can improve atherosclerosis-related parameters by improving lipid profile, oxidative stress, and inflammation. In addition, these compounds may modulate the diversity and composition of the gut microbiota and improve atherosclerosis. The studies evaluated in the present review showed that probiotics and phenolic compounds, when consumed individually, improved atherosclerosis by modulating the gut microbiota in various ways, such as decreasing gut permeability, decreasing TMAO and LPS levels, altering alpha and beta diversity, and increasing fecal bile acid loss. However, no study was found that evaluated the combined use of probiotics and phenolic compounds to improve atherosclerosis. The available literature highlights the synergistic potential between phenolic compounds and probiotics to improve their health-promoting properties and functionalities. This review aims to summarize the available evidence on the individual effects of probiotics and phenolic compounds on AS, while providing insights into the potential benefits of nutraceutical approaches using probiotic strains, quercetin, and resveratrol as potential adjuvant therapies for AS treatment through modulation of the gut microbiota.

Vascular aging, marked by alterations in the structure and function of blood vessels, including heightened arterial stiffness and impaired endothelial function, is linked to a higher likelihood of developing cardiovascular and age-associated pathological conditions. Oxidative stress and inflammation are key stimulation factors in vascular aging. Engaging in healthy dietary habits could enhance the functioning of blood vessels. The aim of this study was to conduct a literature review of the evidence regarding the relationship between food regimens, nutraceuticals, and dietary supplements and vascular health. A search of electronic databases, including PubMed, Scopus, and Web of Science Core Collection, was performed. Experimental and observational studies evaluating the association between food groups, nutraceuticals, supplements, and endothelial function and/or arterial stiffness were deemed eligible for this narrative review. Based on the current body of the included studies, food groups, nutraceuticals, and dietary supplements may not demonstrate superiority over placebos in enhancing markers of vascular health. To obtain more reliable evidence on the effectiveness of interventions in vascular health, additional RCTs with larger sample sizes, extended follow-up periods, and multi-center participation are necessary. Enhancing the credibility of these RCTs requires better control of dietary variables and more precise measurement of vascular health markers. [ABSTRACT FROM AUTHOR]

Mild-to-moderate ulcerative colitis (UC) management is centred on 5-aminosalicylic acid (5-ASA) derivatives. Whether supplementing 5-ASA with nutraceuticals can provide real advantages in UC-relevant outcomes is unclear. This retrospective multicentre study compared clinical remission, response rates, and faecal calprotectin levels in a two-arm design, including patients treated with 5-ASA alone and those with additional H. erinaceus-based multi-compound supplementation. In the 5-ASA alone group, clinical response rates were 41% at three months (T1) and 60.2% at six months (T2), while corresponding clinical remission rates were 16.9% and 36.1%. In the nutraceutical supplementation group, clinical response rates were 49.6% (T1) and 70.4% (T2), with clinical remission rates of 30.4% (T1) and 50.9% (T2). No significant differences in clinical response rates between the groups at T1 (p = 0.231) and T2 (p = 0.143) emerged. Clinical remission rates differed significantly at both time points (p = 0.029 and p = 0.042, respectively). Faecal calprotectin levels decreased significantly in both groups during the retrospective follow-up (p < 0.05), and this was more pronounced in nutraceutical supplementation patients at both T1 (p = 0.005) and T2 (p = 0.01). No adverse events were reported. This multi-component nutraceutical supplementation offers real-world potential in controlling disease activity in patients with mild-to-moderate UC.
