RESUMO
BACKGROUND: Diabetes is a leading health disorder and is responsible for high mortality rates across the globe. Multiple treatment protocols are being applied to overcome this morbidity and mortality including plant-based traditional medicines. This study was designed to investigate the ethnomedicinal status of plant species used to treat diabetes in District Karak, Pakistan. MATERIALS AND METHODS: A semi-structured survey was created to collect data about traditionally used medicinal plants for diabetes and other ailments. The convenience sampling method was applied for the selection of informants. The collected data was evaluated through quantitative tools like frequency of citation (FC), relative frequency of citation (RFC), informant consensus factor (FIC), fidelity level (FL), and use value (UV). RESULTS: A total of 346 local informants were selected for this research. Out of them, 135 participants were men and 211 participants were women. Overall 38 plant species belonging to 29 plant families were used to treat diabetes. The most dominant plant family was Oleaceae having 11 species. Powder form (19%) was the most recommended mode of preparation for plant-based ethnomedicines. Leaves (68%) were the most frequently used parts followed by fruit (47%). The highest RFC was recorded for Apteranthes tuberculata (0.147). The maximum FL was reported for Apteranthes tuberculata (94.4) and Zygophyllum indicum (94.11) for diabetes, skin, and wounds. Similarly, the highest UV of (1) each was found for Brassica rapa, Melia azedarach, and Calotropis procera. Based on documented data, the reported ailments were grouped into 7 categories. The ICF values range between 0.89 (diabetes) to 0.33 (Cardiovascular disorders). CONCLUSION: The study includes a variety of antidiabetic medicinal plants, which are used by the locals in various herbal preparations. The species Apteranthes tuberculata has been reported to be the most frequently used medicinal plant against diabetes. Therefore, it is recommended that such plants be further investigated in-vitro and in-vivo to determine their anti-diabetic effects.

The following investigation was carried out to determine the effects of Selenium nanoparticles (Se NPs) on the growth rates, nutrient digestibility, and hematology of Cirrhinus mrigala fingerlings fed sunflower meal as basal diet. The experiment included seven test diets with varying Se levels (0, 0.5, 1, 1.5, 2, 2.5, and 3â¯mg/kg) based on Se NPs supplementation. Chromic oxide, an inert maker, was also added. Fingerlings were fed at a rate of 5% of their body weight. The test meal of 1â¯mg/kg Se NPs resulted in the highest weight gain (12.31â¯g) and the lowest feed conversion ratio (1.58). Best hematological indices (RBCs 2.84 106 mm-3, WBCs 7.79 103 mm-3, PLT 66, Hb 8.5â¯g/100â¯ml, PCV 25% and MCV 190 fl) and maximum nutrient absorption (crude protein 72%, ether extract 73% and gross energy 67%) were also observed in the case of 1â¯mg/kg supplementation of Se NPs. Hematology studies indicated that when fish were fed 0.5â¯mg/kg Se NPs, their levels began to rise. Maximum results were achieved with feed containing 1â¯mg/kg of Se NPs, but when the concentration increased above 1â¯mg/kg, the values began to decline. Instead, nutrient digestibility began to increase when the concentration of Se NPs increased to 1â¯mg/kg and abruptly started to decline with a further increase in Se NPs. The results demonstrated that a sunflower meal-based diet supplemented with Se NPs (1â¯mg/kg) increased the growth performance, nutritional digestibility, and hematology of C. mrigala fingerlings.

This study was conducted to ascertain the negative effects of dietary low-density polyethylene microplastics (LDPE-MPs) exposure on growth, nutrient digestibility, body composition and gut histology of Nile tilapia (Oreochromis niloticus). Six sunflower meal-based diets (protein 30.95%; fat 8.04%) were prepared; one was the control (0%) and five were incorporated with LDPE-MPs at levels of 2, 4, 6, 8 and 10% in sunflower meal-based diets. A total of eighteen experimental tanks, each with 15 fingerlings, were used in triplicates. Fish were fed at the rate of 5% biomass twice a day for 60 days. Results revealed that best values of growth, nutrient digestibility, body composition and gut histology were observed by control diet, while 10% exposure to LDPE-MPs significantly (P < 0.05) reduced weight gain (WG%, 85.04%), specific growth rate (SGR%, 0.68%), and increased FCR (3.92%). The findings showed that higher level of LDPE-MPs (10%) exposure in the diet of O. niloticus negatively affects nutrient digestibility. Furthermore, the results revealed that the higher concentration of LDPE-MPs (10%) had a detrimental impact on crude protein (11.92%) and crude fat (8.04%). A high number of histological lesions were seen in gut of fingerlings exposed to LDPE-MPs. Hence, LDPE-MPs potentially harm the aquatic health.

In the current research, we produced green, cost-effective, eco-friendly silver nanoparticles using a single-step approach. Plants are considered highly desirable systems for nanoparticle synthesis because they possess a variety of secondary metabolites with significant reduction potential. In the current research, the dried leaf extract of Rubus fruticosus was utilized as a capping and reducing agent for the fabrication of silver nanoparticles, to prepare reliable biogenic silver nanoparticles and subsequently to investigate their potential against some common phytopathogens. The prepared silver nanoparticles were exploited to quantify the total flavonoid content (TFC), total phenolic content (TPC) and DPPH-based antioxidant activity. Different concentrations of aqueous extracts of plant leaves and silver nitrate (AgNO3) were reacted, and the color change of the reactant mixture confirmed the formation of Rubus fruticosus leaf-mediated silver nanoparticles (RFL-AgNPs). A series of characterization techniques such as UV-vis spectroscopy, transmission electron microscopy, energy dispersive X-ray analysis and X-ray diffraction revealed the successful synthesis of silver nanoparticles. The surface plasmon resonance peak appeared at 449 nm. XRD analysis demonstrated the crystalline nature, EDX confirmed the purity, and TEM demonstrated that the nanoparticles are mostly spherical in form. Furthermore, the biosynthesized nanoparticles were screened for in vitro antibacterial activity, antioxidant activity, and total phenolic and flavonoid content. The nanoparticles were used in different concentrations alone and in combination with plant extracts to inhibit Erwinia caratovora and Ralstonia solanacearum. In high-throughput assays used to inhibit these plant pathogens, the nanoparticles were highly toxic against bacterial pathogens. This study can be exploited for planta assays against phytopathogens utilizing the same formulations for nanoparticle synthesis and to develop potent antibacterial agents to combat plant diseases.
