The article processing charge was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – 491192747 and the Open Access Publication Fund of Humboldt-Universität zu Berlin.Plants provide humans with more than just food and shelter; they are also a major source of medications. The purpose of this research was to investigate the antioxidant and hypoglycemic potential of green synthesized CeONPs using Mentha royleana leaves extract. The morphological and physicochemical features of CeONPs were evaluated by UV–Visible spectrophotometry, Scanning Electron Microscopy, Energy Dispersive X-rays and Fourier-transform infrared spectrometry, Dynamic light scattering, Atomic Force Microscopy, Zeta Potential. The average size range of synthesized CeONPs diameter between 46 and 56 nm, crystalline in shape, with Polydispersity index value of 0.2 and subatomic particles mean diameter was 4.5–9.1 nm. The antioxidant capability of CeONPs was assessed using DPPH, ABTS+, hydrogen peroxide, hydroxyl radical scavenging, and reducing power tests. The hypoglycemic potential of CeONPs was investigated using alpha-amylase, alpha-glucosidase, glucose absorption by yeast cells, and antisucrase. The effective concentrations were 500 and 1000 µg/ml found good in suppressing radical species. To explore the hypoglycemic potential of CeONPs, alpha-amylase, alpha-glucosidase, glucose absorption by yeast cell, and antisucrase assays were performed. Glucose absorb by yeast cells assay was tested for three distinct glucose concentrations: 5 mmol/L, 10 mmol/L, and 25 mmol/L. Green synthesize CeONPs showed a dose-dependent response, higher concentrations of CeONPs imposed a stronger inhibitory impact on the catalytic site of enzymes. This study suggest that CeONPs could possibly binds to the charge carrying species and act as competitive inhibitor which slow down the enzyme substrate reaction and prevents enzymatic degradation. The study’s findings were outstanding, which bodes well for future medicinal applications of CeONPs.Peer Reviewe

Mechanistic Approaches to the Application of Nano-Zinc in the Poultry and Biomedical Industries: A Comprehensive Review of Future Perspectives and Challenges

Bio-fortification is a new, viable, cost-effective, and long-term method of administering crucial minerals to a populace with limited exposure to diversified foods and other nutritional regimens. Nanotechnology entities aid in the improvement of traditional nutraceutical absorption, digestibility, and bio-availability. Nano-applications are employed in poultry systems utilizing readily accessible instruments and processes that have no negative impact on animal health and welfare. Nanotechnology is a sophisticated innovation in the realm of biomedical engineering that is used to diagnose and cure various poultry ailments. In the 21st century, zinc nanoparticles had received a lot of considerable interest due to their unusual features. ZnO NPs exhibit antibacterial properties; however, the qualities of nanoparticles (NPs) vary with their size and structure, rendering them adaptable to diverse uses. ZnO NPs have shown remarkable promise in bio-imaging and drug delivery due to their high bio-compatibility. The green synthesized nanoparticles have robust biological activities and are used in a variety of biological applications across industries. The current review also discusses the formulation and recent advancements of zinc oxide nanoparticles from plant sources (such as leaves, stems, bark, roots, rhizomes, fruits, flowers, and seeds) and their anti-cancerous activities, activities in wound healing, and drug delivery, followed by a detailed discussion of their mechanisms of action.Deutsche Forschungsgemeinschaft (DFG, German Research Foundation)Open Access Publication Fund of Humboldt-Universität zu BerlinPeer Reviewe

Effect of phytogenic iron nanoparticles on the bio-fortification of wheat varieties

The article processing charge was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – 491192747 and the Open Access Publication Fund of Humboldt-Universität zu Berlin.Bio-fortification is a potential technique to tackle micronutrient deficiencies that remain. Wheat grain bio-fortification has the ability to decrease malnutrition because it represents one of the most essential staple crops. Bio-fortification is cost-effective and evidence-based sustainable technique to address malnutrition in wheat varieties possessing additional micronutrient contents. Nano-biofortification is a novel approach, enriching crops with essential nutrients in order to supplement human diets with balanced diets. The current study was designed to explore the potential role of phytogenic iron nanoparticles (Fe-NPs) to enhance nutritional contents in wheat plants to fulfill the nutrient deficiency important for human and animal health. In the current study, Fe-NPs were fabricated by using the extract of Mentha arvensis L. that were irregular in shape with an approximate size range of 40–100 nm. Further, Fourier transform infrared (FT-IR) analyses were deployed to confirm the presence of t of various functional groups involved in the green and eco-friendly fabrication of Fe-NPs. The effects of phytogenic Fe-NPs were examined on various physiological and biochemical parameters such as total proline, total chlorophyll, carbohydrates, protein, crude fibers, and lipids contents. Moreover, wheat physiological and biochemical profiling was carried out, and it was noticed that Fe-NPs significantly altered the physico-biochemical profiling of wheat plants. Multiple methods of administration of Fe-NPs were used to fortify the wheat crop. However, the Fe-NPs assisted seed priming along with foliar applications at various concentrations (10, 20, and 30 mg·L−1) were found more suitable to enhance the contents of proline, Chlorophyll a, b, total chlorophyll, carbohydrate, proteins, fibers, and lipids (20.22%, 18.23%, 17.25%, 16.32%, 12.34%, 24.31%, 19.52%, and 11.97%, respectively) in wheat plants. Further, wheat flour was exposed to digestive enzymes, with the iron content gradually increased in a dose-dependent manner. The nutritional analysis of wheat zinc (Zn), molybdenum (Mo), magnesium (Mg), iron (Fe), yttrium (Y), and copper (Cu) and the fatty acid profile have demonstrated divergent patterns of behavior. Similarly, iron content was also increased significantly in response to the exposure to Fe-NPs.Peer Reviewe

Systematic, comprehensive, evidence-based approach to identify neuroprotective interventions for motor neuron disease: using systematic reviews to inform expert consensus

Objectives: Motor neuron disease (MND) is an incurable progressive neurodegenerative disease with limited treatment options. There is a pressing need for innovation in identifying therapies to take to clinical trial. Here, we detail a systematic and structured evidence-based approach to inform consensus decision making to select the first two drugs for evaluation in Motor Neuron Disease-Systematic Multi-arm Adaptive Randomised Trial (MND-SMART: NCT04302870), an adaptive platform trial. We aim to identify and prioritise candidate drugs which have the best available evidence for efficacy, acceptable safety profiles and are feasible for evaluation within the trial protocol. Methods: We conducted a two-stage systematic review to identify potential neuroprotective interventions. First, we reviewed clinical studies in MND, Alzheimer’s disease, Huntington’s disease, Parkinson’s disease and multiple sclerosis, identifying drugs described in at least one MND publication or publications in two or more other diseases. We scored and ranked drugs using a metric evaluating safety, efficacy, study size and study quality. In stage two, we reviewed efficacy of drugs in MND animal models, multicellular eukaryotic models and human induced pluripotent stem cell (iPSC) studies. An expert panel reviewed candidate drugs over two shortlisting rounds and a final selection round, considering the systematic review findings, late breaking evidence, mechanistic plausibility, safety, tolerability and feasibility of evaluation in MND-SMART. Results: From the clinical review, we identified 595 interventions. 66 drugs met our drug/disease logic. Of these, 22 drugs with supportive clinical and preclinical evidence were shortlisted at round 1. Seven drugs proceeded to round 2. The panel reached a consensus to evaluate memantine and trazodone as the first two arms of MND-SMART. Discussion: For future drug selection, we will incorporate automation tools, text-mining and machine learning techniques to the systematic reviews and consider data generated from other domains, including high-throughput phenotypic screening of human iPSCs
