A simple and effective method to synthesize fluorescent nanoparticles using tryptophan and light and their lethal effect against bacteria.

A simple, environmentally friendly and cost-effective method was used to synthesize silver nanoparticles using tryptophan and light. To prepare the nanoparticles, the following components were used: deionized water, silver nitrate, light and tryptophan. The effects of the tryptophan concentration and light exposure time on the formation of tryptophan silver nanoparticles (Tnnps) were studied.

Red blood cell transfusions worsen the outcomes even in critically ill patients undergoing a restrictive transfusion strategy.

Context And Objective: Anemia and blood transfusions are common in intensive care. This study aimed to evaluate epidemiology and outcomes among critically ill patients under a restrictive transfusion strategy.

Design And Setting: Prospective observational cohort study in an intensive care unit (ICU) at a tertiary hospital.
