Prevention of sufentanil-induced cough during induction of general anesthesia by low-dose esketamine.

Background: Sufentanil is commonly used to induce general anaesthesia due to its rapid onset of action, strong analgesic effect, long-lasting effect, and stable haemodynamics; however, it often induces cough, increasing the risk of anaesthesia. This study aimed to investigate the preventive effect of low-dose esketamine on sufentanil-induced cough.

Methods: This randomised, double-blind, placebo-controlled clinical study was conducted at the Air Force Medical Center between September 2023 and May 2024.

Overburden movement law in strip filling mining of upward mining faces.

Strip filling mining significantly improves coal recovery rates and fosters sustainable development in the coal industry. To investigate the overburden movement patterns of strip filling mining, a mine in Tuokexun was selected as the study site. The stability of the composite structure in upward mining faces, as well as the stress distribution and fracture characteristics of the overburden at different stages of strip filling mining, were analyzed using theoretical methods, numerical simulations, and similarity experiments.

Characterization, adsorption kinetic and in vitro release behavior of curcumin loaded with porous mannitol and porous lactose: Template agent method vs. Pore-forming agent method.

Polyvinylpyrrolidone K30 was used as the templating agent, and ammonium bicarbonate was used as the pore-forming agent to make porous mannitol and porous lactose by the template and pore-forming agent method, respectively. Compared with the template method, the porous particles prepared by the pore-forming agent method have larger pore diameter (320.276 nm and 250.

Confirmation of Two Novel HIV-1 CRF01_AE/CRF07_BC Recombinant Forms Among Men Who Have Sex with Men in Hebei, China.

Acquired immune deficiency syndrome caused by human immunodeficiency virus (HIV) is a serious infectious disease because of its' high genetic variability. Nowadays, homosexual contact has become the most predominant transmission route in Hebei province, China, leading to the emergence of novel HIV-1 recombinant forms. The neighbor-joining (N-J) phylogenetic trees were constructed using MEGA 6.

Evolutionary characterization of the establishment of H6 influenza viruses in domestic geese in China: implications for the position of the host in the ecosystem.

Geese, both wild and domestic, are generally considered part of the natural reservoir for influenza A viruses. The highly pathogenic H5 Goose/Guangdong avian influenza virus lineage that is still causing outbreaks worldwide was first detected in domestic geese in 1996. However, while wild geese might have a somewhat restricted role in the influenza ecosystem, the role of domestic geese is little studied.
