An integrated theoretical study on natural alkaloids as SARS-CoV-2 main protease inhibitors: a step toward discovery of potential drug candidates with anti-COVID-19 activity.

: in the twenty-first century, the emergence of COVID-19 as a highly transmissible pandemic disease caused by SARS-CoV-2 posed a significant threat to humanity. : the disease spreads through small respiratory droplets, necessitating the use of various compounds for treatment, with alkaloids being recognized as particularly crucial owing to their diverse pharmaceutical properties. : in this study, a dataset comprising 100 natural alkaloids obtained from the literature was transformed into 2D chemical structures using Chem Draw 19.

Biosynthesis and health promoting traits of green synthesized cobalt oxide nanoparticles.

Nanomedical applications have increased significantly. This work aimed to fabricate and characterize cobalt oxide nanoparticles (CoOnps) synthesized biologically via aqueous Alhagi maurorum extract and evaluate their cytotoxic and antimicrobial impacts. Green-synthesized CoOnps were prepared and analyzed using UV-Vis spectrophotometer UV-vis, Scanning electron microscopy (SEM), Transmission electron microscopy TEM, Energy dispersive X-ray analysis EDAX, Fourier transform infrared, FTIR, and X-ray diffraction (XRD).

Comprehensive analysis and risk assessment of fine road dust in Abbottabad city (Pakistan) with heavy traffic for potentially toxic elements.

Human activities have far-reaching impact on natural ecosystems, causing increasing disturbances and disruptions to the delicate balance of the environment. Poor land use planning, urbanization, infrastructure development, and unplanned tourism exacerbate contamination and degradation in tourist destinations, yet the pollution of potentially toxic elements (PTEs) in these environments remains inadequately explored. To address this issue, we investigated the concentrations of acid-digested PTEs in road dust in Abbottabad city (Pakistan) with heavy traffic.

Enhancing Photothermal Therapy for Antibiofilm Wound Healing: Insights from Graphene Oxide-Cranberry Nanosheet Loaded Hydrogel in vitro, in silico, and in vivo Evaluation.

Background: Diabetic foot ulcers present a formidable challenge due to colonization by biofilm-forming microorganisms, heightened oxidative stress, and continuous wound maceration caused by excessive exudation.

Methods: To address these issues, we developed a robust, stretchable, electro-conductive, self-healing, antioxidant, and antibiofilm hydrogel. This hydrogel was synthesized through the crosslinking of polyvinyl alcohol (PVA) and chitosan (CH) with boric acid.
