Green Synthesis of Silver-Doped ZnO Nanoparticles From Adiantum venustum D. Don (Pteridaceae): Antimicrobial and Antioxidant Evaluation.

One of the main difficulties in nanotechnology is the development of an environmentally friendly, successful method of producing nanoparticles from biological sources. Silver-doped zinc oxide nanoparticles (Ag-ZnO NPs), with antibacterial and antioxidant properties, were produced using Adiantum venustum extract as a green technique. Fresh A.

Factors associated with in-hospital mortality of newborns admitted to a special care newborn unit of a tertiary care hospital in southern Bangladesh: a retrospective cohort study.

Objectives: The objective of this study was to identify factors associated with in-hospital deaths of newborns admitted to a special care newborn unit (SCANU) in southern Bangladesh.

Design: Retrospective cohort.

Setting: SCANU of Patuakhali Medical College Hospital, Patuakhali, Bangladesh.

Physician's perception and practices on antimicrobial resistance in a tertiary care hospital in Bangladesh: a cross-sectional study.

Background: Antimicrobial resistance (AMR) is a global health and development concern. Antimicrobial misuse and overuse are key contributors to the emergence of drug-resistant infections.

Objective: The current study aimed to determine the level of perception and practices of physicians regarding AMR in a tertiary-level hospital.

Photocatalytic removal of textile wastewater-originated methylene blue and malachite green dyes using spent black tea extract-coated silver nanoparticles.

The spent black tea extract was utilized in order to synthesize the spent black tea silver nanoparticles (SBT-AgNPs). Various parameters were tested to yield the best production of SBT-AgNPs. The characterization was conducted by X-Ray diffraction, Scanning electron microscopy, Zeta potential and energy dispersive X-ray (EDX).
