Construction of L-type lectin displaying Saccharomyces cerevisiae for Vibrio parahaemolyticus agglutination.

The utilization of Aga1P anchor protein in the display system for expressing heterologous proteins on the surface of Saccharomyces cerevisiae has been shown to be an ideal approach. This system has the ability to improve the expression of target proteins beyond the cell surface, resulting in increased activity and stability of the expression system. Recent studies have demonstrated that a new L-type lectin from Litopenaeus vannamei (LvLTLC1) has been found to possess the capability of agglutinating Vibrio parahaemolyticus, a pathogen responsible for causing acute hepatopancreatic necrosis disease (AHPND) in shrimp.

Clinical outcomes of concomitant use of enteral and intravenous sedatives and analgesics in mechanically ventilated patients with COVID-19.

Purpose: To evaluate potential differences in days on mechanical ventilation for patients with coronavirus disease 2019 (COVID-19) based on route of administration of analgesic and sedative medications: intravenous (IV) alone vs IV + enteral (EN).

Summary: This institutional review board-approved study evaluated ventilation time and fentanyl or midazolam requirements with or without concurrent EN hydromorphone and lorazepam. Patients were included in the study if they were 18 to 89 years old and were admitted to the intensive care unit with a positive severe acute respiratory syndrome coronavirus 2 reverse transcription and polymerase chain reaction or antigen test and respiratory failure requiring invasive mechanical ventilation for more than 72 hours.
