Medical thoracoscopy combined with intrapleural injection of urokinase for treatment of pleural infection-a multicenter, prospective, randomized controlled study: study protocol.

Background: Pleural diseases is a common respiratory disorder, mainly characterized as pleural effusion and patients with pleural effusion caused by pneumonia and empyema constituted 29% of the cohort, which suggests pleural infection as the predominant etiology of pleural effusion in China. Medical thoracoscopy (MT) combined with intrapleural injection of Urokinase holds significant therapeutic value for patients with early to moderate-stage empyema. However, there remains a lack of high-quality evidence regarding the efficacy and safety of combining MT with intrapleural injection of Urokinase administration in patients with pleural infections.

Strategically constructed hybrid bulk-heterojunction for efficient flexible self-powered infrared photodetectors with a carbon electrode.

The construction of an admirable hybrid bulk-heterojunction (HBH) can benefit the performance of optoelectronic devices through efficient charge separation and transportation. However, the present HBH structure still suffers from complicated layer-by-layer ligand exchanges during device fabrication. In this work, we apply a liquid phase exchange strategy in mixed colloidal hybrids composed of quantum dots (QDs) and nanotetrapods (NTs) and construct low-cost flexible self-powered infrared photodetectors with a carbon electrode.

Comparison of the safety of esophagojejunal overlap and π-shaped anastomosis in totally laparoscopic total gastrectomy.

Background: Globally, totally laparoscopic total gastrectomy is increasingly being accepted by surgeons for the treatment of gastric cancer. Overlap anastomosis and π-shaped anastomosis are the two most commonly used anastomosis methods in total laparoscopic surgery; however, their safety and suitability for the population are still unclear.

Methods: A total of 162 consecutive patients with gastric cancer who underwent total laparoscopic total gastrectomy with overlap or π-shaped anastomosis were retrospectively analyzed.

Recommended Occupational Exposure Limits for GMA Using Benchmark Dose and Bayesian Model Averaging.

Introduction: Glycidyl methacrylate (GMA) is a widely used industrial polymerization material. Current occupational exposure limits (OELs) for GMA in China show significant disparities compared to those established by international regulatory bodies, including the United States, the European Union, and Japan. A comprehensive revision of GMA exposure limits is crucial for ensuring optimal worker protection.

Graphene Supported NiFe-LDH and PbO Catalysts Prepared by Plasma Process for Oxygen Evolution Reaction.

The development of efficient catalysts for water electrolysis is crucial for advancing the low-carbon transition and addressing the energy crisis. This work involves the fabrication of graphene-based catalysts for the oxygen evolution reaction (OER) by integrating NiFe-LDH and PbO onto graphene using plasma treatment. The plasma process takes only 30 min.
