Till now the exact mechanism and effect of biogenic silver nanoparticles on fungus is an indefinable question. To focus on this issue, the first time we prepared hydrothermal assisted thyme coated silver nanoparticles (T/AgNPs) and their toxic effect on Candida isolates were determined. The role of thyme (Thymus Vulgaris) in the reduction of silver ions and stabilization of T/AgNPs was estimated by Fourier transforms infrared spectroscopy, structure and size of present silver nanoparticles were detected via atomic force microscopy as well as high-resolution transmission electron microscopy.

Article Synopsis
  • - The study aimed to assess how common multifocal choroiditis/punctate inner choroidopathy (MFC/PIC) is in patients with patchy atrophy due to pathologic myopia, analyzing 500 eyes from 253 patients between 2014 and 2020.
  • - Results showed that 11% of the examined eyes exhibited signs of active MFC/PIC via optical coherence tomography, with notable features including specific retinal changes and a significant association with macular neovascularization.
  • - The findings suggest that while only a small percentage of eyes with pathologic myopia exhibited active MFC/PIC lesions, these lesions may lead to further complications, like macular neovascularization, and can occur before

Background: On March 13, 2020, Ethiopia reported the first confirmed case of COVID-19 in Addis Ababa. COVID-19 is likely to overwhelm an already-fragile health care delivery system and reduce the availability of essential health services. This analysis of data from the Somali Region of Eastern Ethiopia on health care workers' (HCWs) knowledge, attitudes, and practices regarding the prevention and control of COVID-19 may be used in planning health education programs about the emerging viral disease.
