Green biosynthesis of silver and gold nanoparticles using Teak () leaf extract and its anticancer and antimicrobial activity.

The green synthesis of nanoparticles (NPs) utilizing a green path is eco-friendly and profitable compared to traditional physical and chemical techniques. This research conducted a green synthesis of gold NPs (AuNPs) and silver NPs (AgNPs) using an extract of Teak () and their anticancer and anti-microbial activities. Various techniques like transmission-electron microscopy (TEM), UV-Vis spectroscopy, thermal-gravimetric analyses (TGA), X-ray diffraction (XRD), and Fourier transform-infrared spectroscopy (FT-IR) were used to analyze synthesized AuNPs and AgNPs.

Hydrogen Peroxide 3%: Is it Beneficial in Tonsillectomy?

Objectives: The world over, tonsillectomy is one of the operations most frequently performed by otolaryngologists, who are in search of a technique of tonsillectomy where the operation time and operative blood loss is reduced. This study was carried out to evaluate the effect of hydrogen peroxide 3% on tonsillectomy times, blood loss during the surgery and on the number of ties used.

Methods: A pilot study of 30 patients was carried out in the Department of Otolaryngology of Basrah General Hospital, Iraq, in the period from February to July 2006.
