Retention properties and mechanism of agricultural waste maize whisker on atmospheric mercury.

Mercury (Hg) is a global pollutant transmitted mainly through the atmosphere, posing a serious threat to biological survival and human health. Porous materials, with high specific surface area, high porosity, and high adsorption, are particularly suitable for the purification of atmospheric Hg mixtures. However, plant porous materials are rarely directly used for atmospheric Hg purification.

Effect of dexmedetomidine for prevention of acute kidney injury after cardiac surgery: an updated systematic review and meta-analysis.

Background: Acute kidney injury (AKI) is a serious complication related to cardiac surgery. Several studies have been conducted to investigate the effect of dexmedetomidine administration on AKI prevention.

Objective: To assess if dexmedetomidine is associated with a protective effect of renal function after cardiac surgery.

Effects of Thermal Softening of Double-Lumen Endobronchial Tubes on the Prevention of Postoperative Sore Throat in Smokers: A Randomized Controlled Trial.

Objective: Tracheal intubation-related complications, such as postoperative sore throat (POST), hoarseness, and vocal cords injuries, are not uncommon. It is well known that thermal softening of double-lumen endobronchial tubes (DLTs) has been used to prevent these events from happening in non-smokers; however, no study has ever assessed the effects of thermal softening of DLTs in smokers undergoing one-lung anesthesia. The authors aimed to investigate whether thermal softening of DLT can achieve a better effect in preventing POST.

Performance and retention mechanisms of corn silk to atmospheric heavy metal lead.

Atmospheric heavy metals are seriously harmful, and porous materials have unique advantages in the control of air pollutants. However, the direct use of plant porous materials to purify atmospheric heavy metals are rare. So agricultural waste corn silk with porous structures was selected to analyze the retention capability and mechanism to the atmospheric lead.
