Adnexal Incarceration in a Posterior Pelvic Peritoneal Defect Associated with Ovarian Torsion: A Case Report.

Ovarian torsion is one of the gynecological emergencies and surgical intervention is the standard management for ovarian salvage as well as reveals some unexpected anatomical defects that increase the risk of ovarian torsion. We report a case of a 27-year-old single, nulliparous female taken for diagnostic laparoscopy with suspicion of ovarian torsion. Intraoperatively, we found right adnexa torsion (ovary with tube) along with incarceration of the right ovary and tube into the big peritoneal sac, which was located medial to the right uterosacral ligament.

Exploring the Experimental and Theoretical Studies and Inhibition Mechanism of Passiflora Incarnata Extract as a Novel Green Inhibitor for API 5CT N80 in an Aggressive Environment.

Corrosion is a crucial problem worldwide that heavily affects natural and industrial environments and can cause machinery breakdown and deterioration of construction assemblies, thus threatening the lives of humans and accelerating the consumption of natural metal reservoirs. In this study, we deployed passiflora incarnata extract (PIE) as an eco-friendly green inhibitor to prevent API 5CT N80 (CS-N80) corrosion in 1 M HCl. The chromatograms of the gas chromatography-mass spectroscopy analysis of PIE have identified 25 compounds.

Ammonia energy fraction effect on the combustion and reduced NOX emission of ammonia/diesel dual fuel.

With stringent regulations of internal combustion engine on reducing CO emission, ammonia has been used as an alternative fuel. Investigating how engine-related performance is affected by partial ammonia replacement of diesel fuel is essential for understanding the combustion. Therefore, in this study, a three-dimensional numerical simulation model is developed for the burning of two fuels of diesel and ammonia based on relevant parameters (i.

Advancements in Noble Metal-Decorated Porous Carbon Nanoarchitectures: Key Catalysts for Direct Liquid Fuel Cells.

Noble-metal nanocrystals have emerged as essential electrode materials for catalytic oxidation of organic small molecule fuels in direct liquid fuel cells (DLFCs). However, for large-scale commercialization of DLFCs, adopting cost-effective techniques and optimizing their structures using advanced matrices are crucial. Notably, noble metal-decorated porous carbon nanoarchitectures exhibit exceptional electrocatalytic performances owing to their three-dimensional cross-linked porous networks, large accessible surface areas, homogeneous dispersion (of noble metals), reliable structural stability, and outstanding electrical conductivity.

Constructing WS/WO heterostructured electrocatalyst enriched with oxygen vacancies for accelerated hydrogen evolution reaction.

H produced through hydrogen evolution reaction (HER) is a shining star in the field of clean energy. Significant efforts have been dedicated to develop efficient and stable electrocatalysts to reduce the energy barrier and accelerate the kinetics of Hydrogen evolution reaction (HER) under various environments. Herein, we propose a strategy to accelerate the kinetics of HER under acid and alkaline environments by combining heterostructure engineering with defect engineering.

Appraisal of the adsorption potential of novel modified gellan gum nanocomposite for the confiscation of methylene blue and malachite green.

In the present investigation a novel, environmentally affable and economical, modified gellan gum nanocomposite (MAA-g-GG/Ppy/MMT) was fabricated via free-radical polymerization for the liquid-phase mitigation of Methylene blue (MB) and Malachite green (MG) dyes. The innovation of this work is substantiated by the intentional combination of diverse materials, the strategic incorporation of polypyrrole for enhanced adsorption, and the thoughtful addition of MMT as a nanofiller to address mechanical strength and improve adsorption capacity. The physico-chemical facets of MAA-g-GG/Ppy/MMT and its interaction with the dye molecules were elucidated using FT-IR, SEM-EDX, BET, TEM, and XRD techniques.

Does interatrial communication affect post-operative course of children undergoing tetralogy of Fallot repair? Single centre retrospective cohort study: propensity score matching.

Introduction: During tetralogy of Fallot repair, leaving or even create an interatrial communication may facilitate post-operative course particularly with right ventricle restrictive physiology. The aim of our study is to assess the influence of atrial communication on post-operative course of tetralogy of Fallot repair.

Methods: Retrospectively, we studied all children who had tetralogy of Fallot repair (2003-2018).

Pneumomediastinum and ECG changes during laparoscopic Nissen fundoplication in a child; Case report.

Introduction: Laparoscopic surgeries are becoming more popular in many surgical procedures particularly in pediatric age group. The physical responses and hemodynamic changes that occur during laparoscopic surgery differ between adults and pediatrics.

Case Presentation: We report a sudden hemodynamic instability and abrupt ECG changes associated with pneumomediastinum (PM) during laparoscopic Nissen fundoplication surgery in a 19 months old boy who had gastro-esophageal reflux disease.
