COVID-19 outbreak: current scenario of Pakistan

Abstract: COVID-19 outbreak was first time experienced in the Wuhan City of China at the end of December 2019. Which spread rapidly in China and then worldwide in 209 countries of America, Europe, Australia and Asia including Pakistan. There are more than fifty thousand mortalities and one million plus people have been affected worldwide, while figure increases rapidly. Different steps have been taken worldwide for the control of COVID-19. Even with less resources Pakistan also taken rigorous measures like designed special hospitals, Laboratories for testing, quarantine facilities, awareness campaign and lock down to control the spread of virus. We highlighted the efforts of government to combat this deadly pneumonia.

Green Synthesis of Zinc Oxide (ZnO) Nanoparticles Using Aqueous Fruit Extracts of Myristica fragrans: Their Characterizations and Biological and Environmental Applications.

Abstract: In the present work, bioaugmented zinc oxide nanoparticles (ZnO-NPs) were prepared from aqueous fruit extracts of Myristica fragrans The ZnO-NPs were characterized by different techniques such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, ultraviolet (UV) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), and thermogravimetric analysis (TGA) The crystallites exhibited a mean size of 4123 nm measured via XRD and were highly pure, while SEM and TEM analyses of synthesized NPs confirmed their spherical or elliptical shape The functional groups responsible for stabilizing and capping of ZnO-NPs were confirmed using FTIR analysis The ζ-size and ζ-potential of synthesized ZnO-NPs were reported as 66 nm and -221 mV, respectively, via the DLS technique can be considered as moderate stable colloidal solution Synthesized NPs were used to evaluate for their possible antibacterial, antidiabetic, antioxidant, antiparasitic, and larvicidal properties The NPs were found to be highly active against bacterial strains both coated with antibiotics and alone Klebsiella pneumoniae was found to be the most sensitive strain against NPs (27 ± 173) and against NPs coated with imipinem (26 ± 15) ZnO-NPs displayed outstanding inhibitory potential against enzymes protein kinase (1223 ± 042), α-amylase (7323 ± 042), and α-glucosidase (6521 ± 049) Overall, the synthesized NPs have shown significant larvicidal activity (773 ± 18) against Aedes aegypti, the mosquitoes involved in the transmission of dengue fever Similarly, tremendous leishmanicidal activity was also observed against both the promastigote (7150 ± 070) and amastigote (6141 ± 071) forms of the parasite The biosynthesized NPs were found to be excellent antioxidant and biocompatible nanomaterials Biosynthesized ZnO-NPs were also used as photocatalytic agents, resulting in 88% degradation of methylene blue dye in 140 min Owing to their eco-friendly synthesis, nontoxicity, and biocompatible nature, ZnO-NPs synthesized from M fragrans can be exploited as potential candidates for biomedical and environmental applications
