Is the use of a mask useful in the prevention of covid-19 disease? An Evidence review study

Background and aims: Coronaviruses are important pathogens in humans and animals. In late 2019, a new coronavirus was identified as the cause of a group of pneumonia cases in Wuhan, Hubei Province, China. The disease spread rapidly, resulting in epidemics in China and reports of sporadic cases worldwide. In February 2020, the World Health Organization (WHO) identified COVID-19, which stands for...

UV LED lighting for automated crystal centring

A direct outcome of the exponential growth of macromolecular crystallography is the continuously increasing demand for synchrotron beam time, both from academic and industrial users. As more and more projects entail screening a profusion of sample crystals, fully automated procedures at every level of the experiments are being implemented at all synchrotron facilities. One of the major obstacle...

A new UV-LED device for automatic disinfection of stethoscope membranes.

BACKGROUND Stethoscopes are widely used by doctors and nurses. Poor stethoscope hygiene is a potential source of nosocomial infection. This study aimed to propose an innovative solution, based on the latest advances in ultraviolet (UV) light-emitting diodes (LEDs), for disinfecting stethoscope membranes automatically and efficiently. METHODS Staphylococcus aureus, Escherichia coli, Pseudomona...
