BackgroundThe Omicron variant of SARS-CoV-2 is more transmissible than prior variants of concern (VOCs).It has caused the largest outbreaks in the pandemic, with increases in mortality and hospitalizations.Early data on the spread of Omicron were captured in countries with relatively low case counts, so it was unclear how the arrival of Omicron wou
Motorcycle helmets are essential for reducing the risk of head injuries in the event of an impact.However, during the design of helmets, a compromise must be made between user safety and user comfort.Accordingly, the present study proposes a novel open-face helmet design, in which the helmet features three ventilation slots in the upper-head region
Whole genome duplication events have occurred frequently during the course of vertebrate evolution.To better understand the influence of polyploidization on the fish genome, we herein used the autotetraploid Carassius auratus (4n = 200, RRRR) (4nRR) resulting from the whole genome duplication of Carassius auratus (2n = 100, RR) (RCC) to explore the
Biometric evaluation and reproductive biology of Oreochromis niloticus were studied from Geray Reservoir.Between November 2021 and August 2022, 316 O.niloticus specimens were collected from this reservoir.The Dresser and Changer Top observed male to female sex ratio was 1:1.14, which was statistically insignificant compared with the hypothetical 1:
ABSTRACT Introduction: Most implantations of left ventricular assist devices (LVAD) are performed in low-volume centers.This study aimed to evaluate the procedural learning curve of HeartMate II (HM2) implantations by comparing outcomes between two time periods in a low-volume center.Methods: All 51 consecutive patients undergoing HM2 implantation
