Abstract The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier, is a devastating insect-pest of 29 plants including date palm. It feeds inside the tree bark thus it is difficult to manage using insecticides. Only a few insecticides have been found effective against RPW. Among these insecticide, emamectin benzoate (EMB) is widely used. This insecticide can pose threat human and environmental health as it is used in the form of tree injection. Thus, keeping in view its possible, its sublethal effect on RPW was studied using Age-stage, two sex life table. Life table parameters of the progeny of exposed larvae to LC10, LC25, and LC50 of EMB were computed. Statistically higher fecundity (161.12 per female) was observed in control treatment, while less fecundity was observed in LC50 treatment. Significantly higher values for intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R o ) (0.0376, 1.0383, and 67.13 per day, respectively) were recorded for the control treatment. Contrarily, lower values for r, R o , and λ i.e. 0.0318, 23.82, and 1.0324 per day, respectively were recorded in the LC50 treatment. Decreased population parameters suggest that EMB can be successfully used in for the management of RPW.

Recent advances in the production and use of cellulose nanoparticles are detailed in this review. Global demand for sustainability is on the rise, and fossil fuel use is also on the rise. Consequently, the oil and gas industry must maintain its focus on R&D of new, environmentally friendly technologies and materials. Oil and gas companies are interested in cellulose nanoparticles (CNMs) for several reasons, including their renewable potential, high specific surface area, adjustable surface chemistry, and good mechanical, barrier, thermal, and rheological characteristics. Oil and gas production will become more sustainable and environmentally friendly as a result of all this. There are many manufacturing procedures that may be used to manufacture materials with different structures and physicochemical qualities. Biomedicine, sensing, wastewater treatment, paper and cardboard manufacture, and the packaging sector are just a few of the many fields that benefit from cellulose nanomaterials (CNMs), especially cellulose nanofibers and cellulose nanocrystals. These materials have several desirable characteristics, such as being renewable, having a large surface area, being very stiff and strong under tension, and being very flexible on the surface because of hydroxyl groups. This has led to the scale production of these materials; for example, several companies currently make cellulose nanoparticles in quantities of several tons per day. The remarkable properties of nano-cellulose biopolymers, which may be produced by a wide range of microbes and plant materials, including rice husks, tea leaves, and other agricultural byproducts, have recently attracted more attention due to the development of nanotechnology. Scientists use a range of methods, including chemical, mechanical, and enzymatic processes, to synthesize cellulose nanoparticles from food scraps. Nanomaterials' primary characteristics are defined by their surface functionalization, extraction source, and extraction processes. In this article, we will examine their present production rates and their applications in several areas, including as healthcare, sustainable construction materials, and energy storage and generation. Our focus will be on recent developments and upcoming trends in the production and use of cellulose nanoparticles. The purpose of this article is to provide a synopsis of what is known about cellulose and its technical biological uses, including its ability to heal wounds, transport drugs, construct tissues, and regenerate bones. The most recent findings from both basic and applied research are contained in a comprehensive bibliography. Materials derived from cellulose may be modified to possess the specific physical, mechanical, and chemical characteristics needed for use in the biomedical field. It doesn't take much work to alter cellulose's chemical structure and conjugate it with other materials, including nanoparticles. Because of this, the applications are straightforward to form and process, inexpensive, biodegradable, and biocompatible.

The incidence of chronic diseases in contemporary society has been steadily rising with the ageing population. They place a significant strain on both people and the healthcare system, and they are the leading cause of death. As a result, novel detection methods that allow for early identification of chronic diseases to manage therapy are in high demand. Modern sensing tools have emerged in the form of biosensors, which can detect biomarkers and transform them into quantifiable signals. The fields of environmental science, agriculture, drug discovery, biotechnology, food safety, and medical diagnostics might all benefit from the data they provide. The development of more precise, sensitive, and selective diagnostic tools is, nevertheless, of the utmost importance, as is the ability to identify biomarkers as disease indicators at very low concentrations. Nano biosensors are a new generation of analytical instruments that have evolved from the integration of nanomaterials with biosensors. One promising option for continuous, real-time health monitoring is nanostructured biosensors, which provide exceptional sensitivity, selectivity, and reproducibility. Nano biosensors are categorized in this extensive study according to their size, production process, and transduction mechanism. Also, talk about the latest developments and uses for nano biosensors, and cover some important elements of them, focusing on their electrochemistry and optical characteristics. Further research is needed to fully understand nano biosensors and their potential as a tool for personalized treatment, since there are still many unknowns about their biocompatibility, toxicity, stability, and integration into the human body.

Substantial health issues have recently resulted from the sharp rise of antibiotic-resistant bacteria. Researchers are looking for substitute antimicrobial agents to manage or stop pathogen-induced illnesses. Effective antibacterial drugs are developed using a variety of techniques, and nanoscale is definitely a promising substance in this regard. In this work, it was provided a unique quick sustainable synthesis approach of Mn2O3, CuO and CuO/Mn2O3 using a continuous laser diode (CLD). Manganese (II) acetate, deionized water|(DW), and sodium hydroxide (NaOH) are used to prepare a gelatinous solution of Manganese (II) hydroxide Mn(OH)2. A gelatinous solution of Mn(OH)2 was poured into a circular plate and then it was bombarded by a continuous laser diode. A black powder of Mn2O3 nanoparticles was obtained. The nanoparticles were characterized using various techniques such as Scanning electron microscope (SEM), transmitted electron microscope (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). XRD results of the MnO2 nanoparticles show a high degree of crystallinity. The average particle size of 38 [nm] can be observed for samples prepared at time 30 min was determined by SEM and 30 nm by TEM. Mn2O3, CuO and CuO/Mn2O3 nanoparticles were used for decontamination and inactivation of Escherichia coli, Staphylococcus, pseudomonas and Candid strain clinical isolates as an alternative sterilization method. The Antibacterial activity shows that Mn2O3 has a minimum activity while CuO and CuO/Mn2O3 are more influential. The conclusion considered a new direct way to synthesize of Mn2O3, CuO, and CuO/Mn2O3 nanoparticles that is employed in many scientific applications.

Abstract During cell invasion, large Extracellular Vesicle (lEV) release from host cells was dose‐dependently triggered by Trypanosoma cruzi metacyclic trypomastigotes (Mtr). This lEV release was inhibited when IP3‐mediated Ca2+ exit from the ER and further Ca2+ entry from plasma membrane channels was blocked, but whilst any store‐independent Ca2+ entry (SICE) could continue unabated. That lEV release was equally inhibited if all entry from external sources was blocked by chelation of external Ca2+ points to the major contributor to Mtr‐triggered host cell lEV release being IP3/store‐mediated Ca2+ release, SICE playing a minor role. Host cell lEVs were released through Mtr interaction with host cell lipid raft domains, integrins, and mechanosensitive ion channels, whereupon [Ca2+]cyt increased (50 to 750 nM) within 15 s. lEV release and cell entry of T. cruzi, which increased up to 30 and 60 mpi, respectively, as well as raised actin depolymerization at 60 mpi, were all reduced by TRPC inhibitor, GsMTx‐4. Vesicle release and infection was also reduced with RGD peptide, methyl‐β‐cyclodextrin, knockdown of calpain and with the calpain inhibitor, calpeptin. Restoration of lEV levels, whether with lEVs from infected or uninfected epithelial cells, did not restore invasion, but supplementation with lEVs from infected monocytes, did. We provide evidence of THP‐1 monocyte‐derived lEV interaction with Mtr (lipid mixing by R18‐dequenching; flow cytometry showing transfer to Mtr of R18 from R18‐lEVs and of LAP(TGF‐β1). Active, mature TGF‐β1 (at 175 pg/×105 in THP‐1 lEVs) was detected in concentrated lEV‐/cell‐free supernatant by western blotting, only after THP‐1 lEVs had interacted with Mtr. The TGF‐β1 receptor (TβRI) inhibitor, SB‐431542, reduced the enhanced cellular invasion due to monocyte‐lEVs.

Abstract Background Natural and synthetic plant growth regulators are essential for plant health, likewise these regulators also play a role in increasing organic production productivity and improving quality and yield stability. In the present study, we have evaluated the effects of foliar applied plant growth regulators, i.e., moringa leaf extract (MLE) and mepiquat chloride (MC) alone and in combination MC and MLE on the conventional cotton cultivar (CIM 573) and transgenic one (CIM 598). The growth regulators were applied at the start of bloom, 45 and 90 days after blooming. Results The application of MC and MLE at 90 days after blooming significantly improved the relative growth rate, net assimilation rate, the number of bolls per plant, and seed cotton yield. Likewise, the combined application of MLE and MC at 90 days after blooming significantly boosted the nitrogen uptake in locules, as well as the phosphorus and potassium uptake in the leaves of both cotton cultivars. The application of MLE alone has considerably improved the nitrogen uptake in leaves, and phosphorus and potassium contents in locules of Bt and conventional cotton cultivars. Similarly, Bt cotton treated with MLE at 90 days after blooming produced significantly higher ginning out turn and oil contents. Treatment in combination (MLE + MC) at 90 days after blooming produced considerably higher micronaire value, fiber strength, and staple length in conventional cultivar. Conclusion The natural growth enhancer, MLE is a rich source of minerals and zeatin, improving the nutrient absorption and quality of cotton fiber in both conventional and Bt cotton cultivars.

The main consequence of climate change on temperature is global warming. Over the past century, worldwide temperature has increased, rising by about 0.14 degrees Fahrenheit every year. Rising temperature negatively affects morphology, physiology, and yield of crops. Over the last 5 years, agriculture production in Pakistan affected due to temperature increase. Pakistan is an agriculture based developing country. About 2.2% GDP of Pakistan depends on wheat crop which is 1st major cereal crop and ranked as staple food. Nutritionally it provides proteins, dietary fibers, carbohydrates, calcium, and other important compounds but because of the harmful effects of a high temperature, yield of wheat crop in Pakistan has reduced to lowest levels in the last few years. Heat stress affects wheat plants by reducing growth, raised reactive oxygen species (ROS) production, denature cell membranes, and enzymes activity, decreasing photosynthetic activity and disturbing respiration processes. Improving wheat crop productivity is urgently needed to feed the rapidly growing population. Several techniques like Quantitative Trait Locus mapping, omics techniques, and application of nutrients have been used in the past to mitigate high temperature effect on wheat and other different crop plants. This review critically analyzes the response of wheat towards heat stress and its impacts on wheat crop as well as provides critical information on advanced strategies and techniques for the mitigation of heat stress.

The idea of ecotypes, which refer to unique groups of plants that have evolved to flourish in specific habitats, is gaining attention owing to climate fluctuations and changes in the associated microbiota. The term "ecotype" described plant populations that are specially adapted to particular environments, as revealed by common garden experiments showcasing genetically distinct characteristics. This concept remains relevant in modern plant science, where garden experiments continue to uncover how natural selection promotes species diversity, underscoring the crucial role of the plant microbiota in adaptation. Recent research has highlighted the microbial interactions that aid plants in adapting to environmental stress. Plants that shape soil microbial communities exhibit differential responses along ecological gradients owing to environmental stressors that influence interactions with soil microorganisms. Understanding the differentiation within plant populations and the emergence of new species is vital for discerning natural selection patterns. Environmental stressors profoundly impact global crop production, whereas plant-microbiota symbioses significantly influence plant growth and defense through nutrient acquisition and metabolite synthesis. Plant adaptation mechanisms include enzymatic antioxidant production and osmolyte accumulation, which are regulated by phytohormones that orchestrate responses to biotic and abiotic stressors, respectively. Despite breeding and genetic engineering efforts, progress in enhancing plant tolerance to extreme conditions remains limited, necessitating the development of sustainable agricultural alternatives. This study offers a comprehensive overview of recent advances in plant ecotype research, particularly focusing on symbiotic relationships with the microbiota and traits that contribute to improved nutrient uptake and plant health.

The integration of behavioral health services in primary care has become increasingly popular in pediatric settings in recent years. While there are various models of integrated behavioral health (IBH), the aim is constant: to increase access to behavioral and mental health care through collaboration between behavioral health providers and physicians. Prior to the pandemic, only 20%-50% of children and adolescents received mental health care from a professional. Since COVID-19, access to care has only worsened. Given this reality, the use of IBH has promising benefits, including: (1) positive outcomes for patients and providers; (2) improved screening, identification, and intervention; (3) improved mental health outcomes; and (4) reduction of provider burnout. Given these aims and outcomes, a major opportunity exists for school psychologists to bring unique, but highly transferable, knowledge and skills to an emerging field. In this article, the authors share the real-life experiences of a licensed school psychologist and advanced practicum student to highlight how the comprehensive training of school psychologists prepares us to perform well in an integrated setting. The authors also call attention to the numerous possibilities available for those looking for an alternative setting or expansion of their current practice.

Amyotrophic Lateral Sclerosis (ALS) is a severe neurodegenerative disorder marked by the gradual loss of motor neurons, leading to significant disability and eventual death. Despite ongoing research, there are still limited treatment options, underscoring the need for a deeper understanding of the disease’s complex mechanisms and the identification of new therapeutic targets. This review provides a thorough examination of ALS, covering its epidemiology, pathology, and clinical features. It investigates the key molecular mechanisms, such as protein aggregation, neuroinflammation, oxidative stress, and excitotoxicity that contribute to motor neuron degeneration. The role of biomarkers is highlighted for their importance in early diagnosis and disease monitoring. Additionally, the review explores emerging therapeutic approaches, including inhibitors of protein aggregation, neuroinflammation modulators, antioxidant therapies, gene therapy, and stem cell-based treatments. The advantages and challenges of these strategies are discussed, with an emphasis on the potential for precision medicine to tailor treatments to individual patient needs. Overall, this review aims to provide a comprehensive overview of the current state of ALS research and suggest future directions for developing effective therapies.

Plant Growth-Promoting Rhizobacteria (PGPR) play a crucial role in the enhancement of plant growth. These microorganisms inhabit plant roots and positively influence plant growth through various mechanisms. PGPR facilitate nutrient absorption, combat pathogens, and regulate plant hormone levels. Their impact is achieved through direct actions such as hormone production, enhanced iron uptake via siderophores, phosphate solubilization, and emission of volatile compounds that affect plant signaling and metabolism. In addition, PGPR interactions with rhizosphere microorganisms and the soil indirectly improve plant growth. Numerous biotic stressors affect plant PGPR. The interaction between plants and microorganisms boosts the host resistance to biotic stress. This interaction also regulates the rhizosphere soil by converting organic compounds into plant-absorbable forms, increasing molecule mobilization, and supplying amino acids, carbohydrates, lipids, metabolites, and phytohormones to the host plants. In instances where plants do not secrete lipids, amino acids, carbohydrates, or terpenoids during these interactions, microorganisms contribute these compounds to plants. Investigating these mechanisms, along with changes in gene expression and receptor-mediated signaling in plants, is vital. Utilization of microbial sources as alternatives to conventional agricultural methods is a promising approach. Incorporation of these sources can enhance plant production, quality, growth, and yield.

Prostate cancer is the second most common neoplasia and fifth-leading cause of cancer death in men worldwide. Electromagnetic and magnetic fields have been classified as possible human carcinogens, but current understanding of molecular and cellular pathways involved is very limited. Effects due to extremely low magnetic/hypomagnetic fields (LMF) are furthermore poorly understood. Extracellular vesicles (EVs) are crucial mediators of cellular communication with multifaceted roles in cancer progression, including via transport and uptake of various protein and microRNA (miRNA) EV-cargoes. miRNAs regulate gene expression and are implicated in cancer-related processes such as proliferation, metastasis, and chemoresistance. This study investigated the effects of LMF exposure (20 nT) by magnetic shielding on the prostate cancer cell line PC3 compared to the prostate epithelial cell line PNT2 under short-term (4 h) conditions. We examined EV profiles following a 4 h LMF exposure alongside associated functional enrichment KEGG and GO pathways for the EV proteomes. The 4 h LMF exposure significantly reduced cellular EV release and modified PC3 EV cargoes to a more inflammatory and metastatic profile, with 16 Disease Pathways and 95 Human Phenotypes associated specifically with the LMF-treated PC3 EV proteomes. These included cancerous, metabolic, blood, skin, cardiac and skeletal Disease Pathways, as well as pain and developmental disorders. In the normal PNT2 cells, less EV protein cargo was observed following LMF exposure compared with cells not exposed to LMF, and fewer associated functional enrichment pathways were identified. This pointed to some differences in various cellular functions, ageing, defence responses, oxidative stress, and disease phenotypes, including respiratory, digestive, immune, and developmental pathways. Furthermore, we analysed alterations in matrix metalloproteinases (MMPs) and miRNAs linked to metastasis, as this is crucial in cancer aggressiveness. The 4 h LMF exposure caused a significant increase in MMP2 and MMP9, as well as in onco-miRs miR-155, miR-210, miR-21, but a significant reduction in tumour-suppressor miRs (miR-200c and miR-126) in the metastatic PC3 cells, compared with normal PNT2 cells. In addition, 4 h LMF exposure significantly induced cellular invasion of PC3 cells. Overall, our findings suggest that changes in magnetic field exposures modulate EV-mediated and miR-regulatory processes in PCa metastasis, providing a basis for exploring novel therapeutic strategies.

Background: Last year, the human monkeypox virus (hMPXV) emerged as an alarming threat to the community, with a detectable outbreak outside the African continent for the first time. According to The American Centers for Disease Control and Prevention (CDC), the virus is reported globally, with 86,746 confirmed cases (until April 08, 2023). DNA-dependent RNA polymerase (DdRp) is an essential protein for viral replication; hence it is a promising drug target for developing antiviral drugs against DNA viruses. Therefore, this study was conducted to search for natural compounds that could provide scaffolds for RNA polymerase inhibitors. Methods: In this study, the DdRp structure of hMPXV was modeled and used to screen the natural compounds database (COCONUT). The virtual screening revealed 15 compounds able to tightly bind to the active site of the DdRp (binding energies less than −7.0 kcal/mol) compared to the physiological nucleotide, guanosine triphosphate (GTP). Molecular dynamics simulation was then performed on the top four hits and compared to GTP Results: The results revealed the potential of four compounds (comp289, comp295, comp441, and comp449) in binding the hMPXV DdRp active site with a comparable binding affinity (−17.06 ± 2.96, −11.6 ± 5.34, −14.85 ± 2.66, and −10.79 ± 4.49 kcal/mol) with GTP (−21.03 ± 7.55 kcal/mol) Conclusion: These findings may also pave the way for developing new hMPXV inhibitors based on natural product scaffolds. These results need further experimental validation but promising as it was validated by unbiased all-atom MD simulations and binding free energy calculations.

Abstract In this work, the effect of the molar ratio of (Ni2+ and Fe3+) on the properties of CdO–NiO–Fe2O3 nanocomposites was investigated. The synthesis of CdO–NiO–Fe2O3 nanocomposites was carried out by self-combustion. XRD, UV–Vis, PL and VSM were used to describe the physical properties of the materials. The results showed significant progress in structural and optical properties supporting antibacterial activity. For all samples, the particle size decreased from 28.96 to 24.95 nm with increasing Ni2+ content and decreasing Fe3+ content, as shown by the XRD pattern, which also shows the crystal structure of cubic CdO, cubic NiO, and cubic γ-Fe2O3 spinel. The Ni2+ and Fe3+ contents in the CdO–NiO–Fe2O3 nanocomposites have also been shown to enhance the ferromagnetic properties. Due to the significant coupling between Fe2O3 and NiO, the coercivity Hc values of the samples increase from 66.4 to 266 Oe. The potential of the nanocomposites for antibacterial activity was investigated against Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa, Escherichia coli, and Moraxella catarrhalis) bacteria. Comparison of P. aeruginosa with E. coli, S. aureus and M. catarrhalis showed that it has a stronger antibacterial activity with a ZOI of 25 mm.

Drought stress (DS) is one of the most destructive abiotic stresses that negatively affects plant growth, and yield. The intensity of DS is continuously increasing due rapid of water sources, less rainfall, and an increase in global warming. The world’s population is increasing at an alarming rate which needs a substantial increase in crop production to meet global food needs. Therefore, in this context, we must have to increase crop production in the scenarios of rapid climate change and increasing intensity of abiotic stresses. Globally, different measures are used to mitigate the adverse impacts of DS, recently biochar (BC) has emerged as an excellent soil amendment to mitigate the toxic effects of DS and improve crop production. The application maintains membrane integrity, plant water relations, nutrient homeostasis, photosynthetic performance, hormonal balance and osmolytes accumulation, and gene expression thereby improving plant performance under DS. Moreover, BC application under DS also improves soil organic matter, water holding capacity, soil structure stability, and activity of beneficial microbes which can improve the plant performance under DS. In the present review different mechanisms through which BC mitigates the adverse impacts of DS on plants are discussed. This review provides new suggestions on the role of BC in mitigating the adverse impacts of DS.

Mung bean (Vigna radiata) is the rich source of fiber and essential nutrients. They play a vital role in sustainable agriculture due to their ability to fix nitrogen in the soil and enhance soil fertility. Drought is characterized by limited water resources and severe arid climatic conditions, notably impair crop growth and yield. In the current experiment, two genotypes, Azri-M 2006 and NM-92, were studied against drought stress that was applied as 2 days and 4 days irrigation gap per week. Foliar application of magnesium-silicate (20 ppm and 30 ppm concentrations) and Moringa leaf extract (30% v/v solution) was applied as treatments. The results from the experiment morphology anatomical and yield components were recorded according to the prescribed methods. The result revealed that drought stress reduced the growth of plant. Foliar application of 30 ppm silicon against drought stress showed a highly significant (p

Durum and bread wheat are well adapted to the Mediterranean Basin. Twenty-three genotypes of each species were grown to evaluate the intra- and inter-genetic diversity based on omega (ω), gamma (γ) and alpha (α)-gliadin profiles. To achieve this purpose, the endosperm storage proteins (both gliadins and glutenins) were extracted from wheat grains and electrophoresed on sodium dodecyl sulfate (SDS)–polyacrylamide gels. The results of SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE) revealed nine polymorphic loci out of 16 loci with durum wheat genotypes and nine polymorphic loci out of 18 loci with bead wheat genotypes. The polymorphisms revealed by the SDS-PAGE were 56% and 50% in durum and bread wheat genotypes, respectively. Using the cluster analysis, the durum wheat genotypes were clustered into five groups, while the bread wheat genotypes were grouped into six clusters using un-weighed pair group mean analyses based on ω, γ, and α-gliadins profiles. The 46 durum and bread wheat genotypes were grouped into seven clusters based on the combined ω, γ, and α-gliadins profiles revealed by the SDS-PAGE. The in silico analysis determined the intra-genetic diversity between bread and durum wheat based on the sequences of ω, γ, and α-gliadins. The alignment of ω-gliadin revealed the highest polymorphism (52.1%) between bread and durum wheat, meanwhile, the alignment of γ and α-gliadins revealed very low polymorphism 6.6% and 15.4%, respectively. According to computational studies, all gliadins contain a lot of glutamine and proline residues. The analysis revealed that the bread wheat possessed ω and γ -gliadins with a lower content of proline and a higher content of glutamine than durum wheat. In contrast, durum wheat possessed α-gliadin with a lower content of proline and a higher content of glutamine than bread wheat. In conclusion, the SDS-PAGE, in silico and computational analyses are effective tools to determine the intra- and inter-genetic diversity in tetraploid and hexaploid wheat genotypes based on ω, γ, and α-gliadins profiles.
