Horse gram flour and its extracts are examined in this study as a low-cost mineral source with documented anti-urolithiatic and anti-diabetic properties. Further, this study compares these biological activities with those observed in biosynthesized AgNPs. Horse gram's potential as a promising herbal product is further substantiated by the presence of both secondary metabolites and macro and micronutrients within the selected product. The findings of this study reveal that the biomass utilized, an economical natural material, exhibits a significant mineral composition, including calcium (4306 mg/L), followed by potassium (1378 mg/L), and sodium (694 mg/L). The extracted water from the grain displayed a pronounced carbohydrate presence, equivalent to 6510.095 mg per gram. Water and ethanol extracts possess comparable TPC (phenol) content, 6013.245 mg/g and 6824.133 mg/g respectively. However, a substantial divergence is evident in the terpenoid (TTC) content, with 5321.14 mg/g in water and only 51.27 mg/g in ethanol extracts. A concentration of 265 milligrams per gram was observed, this was followed by 4558 17 milligrams per gram of sterols, and then 5727 165 milligrams per gram in moderate amounts, respectively. The aqueous extract of Horse gram was used in a straightforward green synthesis protocol to produce AgNPs. These nanoparticles were then characterized by FESEM, TEM, zeta potential, X-ray diffraction, UV spectroscopy, and particle size measurements. pla pathway The research indicates the generation of AgNPs, displaying an average particle size of 30 nanometers to 60 nanometers. Investigating anti-urolithiatic properties using aqueous extract (HGW), ethanol extract (HGE), and biosynthesized silver nanoparticles (HG-Ag) shows that biosynthesized silver nanoparticles exhibit the superior inhibitory activity compared to the other two samples. The inhibitory effects of the extracts and Ag nanoparticles on crystal growth, at 2% for extracts and 200 g/ml for AgNPs, were further corroborated by the disintegration of crystals in the gel medium. In contrast, the other two extracts (HGW Extract at 6718%, and HGE Extract at 4429%) are outperformed by the HG-Ag nanoparticle, which displays substantial anti-diabetic activity (7536%). Consequently, the seed flour extracts, along with their AgNps, exhibit promising natural herbal characteristics, potentially rich in minerals, showcasing antidiabetic and anti-urolithiatic properties, and thus suitable for incorporation as a valuable ingredient in dietary formulations.

For humans, animals, and plants to thrive, water is absolutely necessary. Numerous studies have explored the incidence and antibiotic resistance of the bacterium Escherichia coli (E.). Though coliform bacteria are found in water from several African nations, a thorough and extensive examination of the available literature on this subject is scarce. A systematic review and meta-analysis, adhering to PRISMA guidelines, was undertaken. English-language articles published between January 2000 and March 2022 were retrieved from ScienceDirect, PubMed, Google Scholar, Scopus, the African Journal Online (AJO), and the Africa Index Medicus (AIM). The application of Comprehensive Meta-Analysis (CMA) Ver 30 software led to the analysis of the data. Using the random-effects model (CI), the pooled prevalence estimate (PPE) with its 95% confidence interval was computed. 4009 E. coli isolates, stemming from 2586 water samples, were subject to a screening to reveal overall patterns in PPE and antimicrobial resistance. In Africa, across 27 countries, 17 research studies yielded 3438 isolates, including samples from drinking water (n=6), rivers (n=5), wastewaters (n=4), and wastewater/river sources (n=1). E. coli protective equipment (PPE) in water showed a percentage of 717%. The 95% confidence interval for the study is 0562%–0833%. In PPE antibiotics, penicillin exhibited the highest resistance (934%), followed by erythromycin (923%) and ampicillin (694%), respectively. Through a systematic review, this report underscores the consolidated prevalence of E. coli and its antibiotic resistance profiles, along with crucial areas across Africa for future investigations and improved data reporting.

This investigation presents the synthesis of novel magnetic nanocomposite materials comprising zinc oxide-zinc sulfide in various molar ratios, along with the synthesis of photocatalysts MNPs@BNPs@ZnO and MNPs@BNPs@ZnS. The hybrid nanocomposites' photocatalytic action, under visible and ultraviolet illumination, was studied for its ability to eliminate methylene blue (MB), methyl orange (MO) dyes, as well as real textile and carton effluents. Through extensive analysis of various photocatalysts, MNPs@BNPs@ZnO-ZnS (ZnO/ZnS 0750.25) is identified as the most effective active photocatalyst for both visible and ultraviolet light, demonstrating optimal results in the ultraviolet region. The TEM analysis revealed that the average particle size of MNPs@BNPs@ZnO-ZnS (ZnO/ZnS 0750.25) nanoparticles falls within the 10-30 nm range. From DLS zeta potential measurements, it was observed that the photocatalyst surface exhibited a negative charge at most pH values. PL analysis of the photocatalyst samples showed that the optimal material exhibited a reduced rate of hole-electron recombination compared with MNPs@BNPs@ZnO and MNPs@BNPs@ZnS. The rate constants for the removal of azo dyes, such as MO (0.0186 min⁻¹) and MB (0.0171 min⁻¹), were ascertained through kinetic studies. Importantly, the synthesized photocatalysts, alongside the inexpensive, durable, and highly efficient UV and visible lamps used in this study, are noteworthy.

Prioritizing watersheds is viewed as an essential strategy for managing soil and watershed resources. This study prioritizes watersheds in Kailali district, Nepal, based on soil erosion, employing GIS, morphometric parameters, and land use/land cover (LULC) data. By leveraging the 30-meter resolution of the ALOS DEM, sub-watersheds were delineated, and subsequent calculation of linear, areal, and relief morphometric parameters was undertaken. The Esri LULC 2021 dataset, utilizing Sentinel-2 imagery at a 10-meter resolution, was employed to compute LULC parameters. The prioritization process incorporated both Principal Component Analysis (PCA) and Weighted Sum Analysis (WSA) in an integrated manner. PCA was chosen to achieve the reduction of the selected parameters, along with the calculation of the correlation matrix and the definition of the significant parameters. Weightage values were derived from WSA, and the Compound Value (CV) was applied in the sub-watershed ranking process. A prioritization process targeted 22 sub-watersheds, each displaying a third-order or higher stream, encompassing 15 parameters. Prioritization was found to be effectively addressed by the integration of PCA and WSA. The watershed study revealed that approximately 6158% of the area falls into the high-priority erosion risk category. Thus, to prevent further soil erosion, a sequential strategy involving land rehabilitation programs and bioengineering techniques should be adopted, beginning with high-priority sub-watersheds and moving down to medium and low priority categories. For multi-hazard mapping, the implemented prioritization approach remains effective and applicable.
