Pyridoxine Prevents Postoperative Nausea and Vomiting in Gynecological Laparoscopic Surgery: A Double-blind Randomized Controlled Trial.

Background: Postoperative nausea and vomiting (PONV) are common complications after gynecological laparoscopic surgery. Pyridoxine has been recommended as a first-line drug to prevent and treat nausea and vomiting during pregnancy; however, its efficacy in preventing PONV remains unclear.

Methods: Patients of 18 to 65 years old, who received elective gynecological laparoscopic surgery under general anesthesia, were randomized into either the pyridoxine or control group.

Effects of Ti Doping on the Structural Stability and Electrochemical Performance of Layered P2-NaMnO Cathodes for Sodium-Ion Batteries.

The P2-NaMnO cathode material has long been constrained by phase transitions induced by the Jahn-Teller (J-T) effect during charge-discharge cycles, leading to suboptimal electrochemical performance. In this study, we employed a liquid phase co-precipitation method to incorporate Ti during the precursor MnO synthesis, followed by calcination to obtain NaTiMnO materials. We investigated the effects of Ti doping on the structure, morphology, Mn concentration, and Na diffusion coefficients of NaTiMnO.

Functional Characterization of , a Gene Coding an Aspartic Acid Protease in .

Aspartic proteases (APs), hydrolases with aspartic acid residues as catalytic active sites, are closely associated with processes such as plant growth and development and fungal and bacterial pathogenesis. is the dominant pathogenic fungus that causes Fusarium head blight (FHB) in wheat. However, the relationship of APs to the growth, development, and pathogenesis of .

Total Syntheses of Diepoxy-Kaurane Diterpenoids Enabled by a Bridgehead-Enone-Initiated Intramolecular Cycloaddition.

Here, we report the enantioselective total syntheses of four diepoxy--kaurane diterpenoids including (-)-Macrocalin B, (-)-Acetyl-macrocalin B, and (-)-Isoadenolin A and the revised structure of (-)-Phyllostacin I, which hinges on the strategic design of a regioselective and stereospecific trapping of a highly reactive [3.2.1]-bridgehead enone intermediate via a tethered intramolecular Diels-Alder reaction.

Evaluating PAX1/JAM3 methylation for triage in HPV 16/18-infected women.

Objective: Referring all women who tested positive for human papillomavirus (HPV) 16/18 to colposcopy may lead to potential over-referral issues. Triage tests based on cytology results face challenges in achieving accurate diagnoses. Our study aims to assess the clinical effectiveness of PAX1/JAM3 methylation (CISCER) test as a triage method for HPV 16/18-positive women.
