Structural, Elastic, Electronic, Dynamic, and Thermal Properties of SrAlO with an Orthorhombic Structure Under Pressure.

Its outstanding mechanical and thermodynamic characteristics make SrAlO a highly desirable ceramic material for high-temperature applications. However, the effects of elevated pressure on the structural and other properties of SrAlO are still poorly understood. This study encompassed structural, elastic, electronic, dynamic, and thermal characteristics.

Addition of Dexmedetomidine to the Anesthesia Regimen Attenuates Pain and Improves Early Recovery After Esophageal Endoscopic Submucosal Dissection: A Randomized Controlled Trial.

Objective: Postoperative pain is a common yet often underestimated complication following esophageal endoscopic submucosal dissection (ESD), with limited strategies for effective management. This prospective, double-blind, randomized controlled trial assessed the effects of adding dexmedetomidine (DEX) to the anesthesia regimen on postoperative pain and early recovery in patients undergoing esophageal ESD.

Methods: In total, 60 patients scheduled for elective esophageal ESD under general anesthesia were randomly assigned to the DEX or control group.

Application value of real-time 3D speckle tracking imaging in left atrial function evaluation of patients with paroxysmal atrial fibrillation.

Objective: To evaluate left atrial volume and function in patients with paroxysmal atrial fibrillation (AF) combined with left atrial appendage thrombosis and patients with paroxysmal AF without left atrial appendage thrombosis by 3-dimensional speckle tracking imaging (3D-STI), and to explore the application value of this set of parameters in the evaluation of left atrial function in patients with paroxysmal AF.

Materials And Methods: A total of 40 patients with paroxysmal AF admitted from December 2018 to December 2020 were selected as the observation group. All patients with paroxysmal AF in the observation group underwent transesophageal echocardiography.

Long-term chemical and organic fertilization induces distinct variations of microbial associations but unanimous elevation of soil multifunctionality.

Intricate microbial associations contribute greatly to the multiple functions (multifunctionality) of natural ecosystems. However, the relationship between microbial associations and soil multifunctionality (SMF) in artificial ecosystems, particularly in agricultural ecosystem with frequent fertilization, remains unclear. In this study, based on a 28-year paddy field experiment, high-throughput sequencing and networks analysis was performed to investigate changes in soil microbial (archaea, bacteria, fungi, and protists) associations and how these changes correlate with SMF under long-term fertilization.

Comparison of the effects of esketamine, sufentanil, or lidocaine combined with propofol on tussis reflection during upper gastrointestinal endoscopy: study protocol for a randomised, two centre, three-blind, controlled trial.

Background: Tussis, which increases the incidence of airway spasm, aspiration, nausea, and vomiting, is a common complication faced during upper gastrointestinal (GI) endoscopy. However, sedatives and analgesics exhibit inhibitory actions against airway reflexes to different degrees. Our assumption is a combination of propofol and small doses of sufentanil, esketamine, or lidocaine, especially the combination of propofol and esketamine, might reduce tussis incidence.

Endoscopic ultrasound-guided gallbladder endoscopic mucosal resection: a pilot porcine study.

Introduction: Endoscopic ultrasound (EUS)-guided natural orifice transluminal gallbladder polypectomy provides a minimally invasive alternative to cholecystectomy. The study aimed to investigate the feasibility and safety of protocol for gallbladder endoscopic mucosal resection (gEMR) under EUS guidance using a porcine model.

Material And Methods: Fifteen Bama mini pigs were randomly divided into the control (CG, = 3) and experimental (EG, = 12) groups.

Long-term partial replacement of mineral fertilizer with in situ crop residues ensures continued rice yields and soil fertility: A case study of a 27-year field experiment in subtropical China.

High yields and environment-related issues because of over-fertilization in rice (Oryza sativa L.) production is a major concern in China. Partial replacement of mineral fertilizer (MF) with organic matter is considered a win-win approach for resource-saving and environmentally friendly rice production.
