The mask effectively prevented the spread of aerosols and reduced droplet spread during simulated transnasal endoscopic skull base surgery in laboratory conditions. This device has potential benefits in protecting surgical personnel against airborne transmission of COVID-19 and could be useful in reducing chronic exposure to the hazard of surgical…[Read more]

tessellata. The study could help in understanding the adaptation mechanism of in vitro regenerated plantlets (especially velamen tissues of epiphytic roots) when transferred to the greenhouse for acclimatization. RESEARCH HIGHLIGHTS Vanda tessellata is an epiphytic orchid of horticultural importance. Comparative micro-morpho-anatomical analysis at…[Read more]

surgery compared with paravertebral blocks. Patients who received ESP blocks had similar consumption of oxycodone and length of hospital stay. Morphogenesis is an essential process by which a given tissue, organ or organism acquires its final shape. A select number of mechanisms are used in order to drive epithelial morphogenesis, including cell…[Read more]

Spontaneous hepatitis B surface antigen (HBsAg) seroclearance, the functional cure of hepatitis B infection, occurs rarely. Prior original studies are limited by insufficient sample size and/or follow-up, and recent meta-analyses are limited by inclusion of only study-level data and lack of adjustment for confounders to investigate HBsAg…[Read more]
