Biodegradation and mechanical performance of Silane-chitosan-graphene oxide composite coating on AZ31 magnesium alloys for biomedical applications.

Biodegradable magnesium alloy medical implants have attracted considerable interest thanks to their remarkable biocompatibility and mechanical properties. However, the rapid corrosion rate of magnesium alloys in physiological environments presents a major challenge to their practical application. Therefore, this study attempted to design a silane/chitosan /graphene oxide composite coating that reduces the corrosion and enhances the biodegradation of magnesium alloys used in temporary implants.

Pharmacological and ameliorative effects of Withania somnifera against cadmium chloride-induced oxidative stress and immune suppression in Nile tilapia, Oreochromis niloticus.

This study was carried out to evaluate the effects of dietary supplementation of aqueous extract of Withania somnifera (W. somnifera) against cadmium chloride-induced toxicity in the Nile tilapia, Oreochromis niloticus. Five experimental groups were designed: group (I) was free from cadmium chloride and W.

Long-term effects of one-anastomosis gastric bypass on liver histopathology in NAFLD cases: a prospective study.

Purpose: Weight reduction can effectively improve nonalcoholic fatty liver disease (NAFLD), which is a constant companion of severe obesity. This study aimed to determine the effect of one-anastomosis gastric bypass (OAGB) on pathological liver changes in severely obese cases with NAFLD.

Methods: The present prospective research comprised 67 subjects with morbid obesity scheduled for OAGB during the period from February 2015 to August 2018.

Acceleration of Gastric Emptying and Improvement of GERD Outcome After Laparoscopic Sleeve Gastrectomy in Non-diabetic Obese Patients.

Purpose: Obesity has become a pandemic nowadays. Bariatric surgery is increasingly performed to manage obesity. Currently, laparoscopic sleeve gastrectomy (LSG) is a widely accepted procedure given its feasibility and efficacy.

Effect of weight loss induced by laparoscopic sleeve gastrectomy on liver histology and serum adipokine levels.

Background & Aim: Bariatric surgery is a valid treatment option for persons with non-alcoholic fatty liver disease. This study prospectively examined the impact of laparoscopic sleeve gastrectomy (LSG) on liver histopathology, and blood levels of adiponectin, leptin, resistin, and pre-B cell enhancing factor/Nampt/visfatin.

Patients & Methods: In 81 patients with non-alcoholic fatty liver disease who underwent LSG, paired liver biopsies and blood specimens were obtained before and 18 months after LSG.

Impact of laparoscopic sleeve gastrectomy on fibrosis stage in patients with child-A NASH-related cirrhosis.

Purpose: Bariatric surgery can improve non-alcoholic fatty liver disease (NAFLD). Yet data on the effect on fibrosis are insufficient and controversial. This work endeavored to evaluate the safety of laparoscopic sleeve gastrectomy (LSG) in cases that have compensated non-alcoholic steatohepatitis (NASH)-related cirrhosis and its impact on fibrosis stage.

Sarcopenia increases 1-year mortality after surgical resection of hepatocellular carcinoma.

Background: Liver resection is a well-recognized modality for hepatocellular carcinoma. Cirrhotic patients are more prone to adverse consequences after liver resection. This work assesses the prognostic significance of sarcopenic hepatocellular carcinoma cases for whom surgical resection was performed.

Laparoscopic Sleeve Gastrectomy on the Horizon as a Promising Treatment Modality for NAFLD.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is viewed as the hepatic manifestation of the metabolic syndrome with hepatic fatty infiltration is the common liver pathology. NAFLD can lead to nonalcoholic steatohepatitis (NASH), liver cirrhosis, liver cell failure, and liver malignancy.The present work aims to prospectively study the histological changes that occur in NAFLD obese patients 1-year post-laparoscopic sleeve gastrectomy (LSG) based on standardized NAS (NAFLD activity score).

Robotic laparoscopic radical cystectomy inhalational versus total intravenous anesthesia: a pilot study.

Background: Robotic assistance may refine laparoscopic radical cystectomy. Steep Trendelenburg tilt (TT) and pneumoperitoneum (PP) are challenging anesthesia maneuvers. In view of those maneuvers, would inhalational anesthesia or total intravenous anesthesia (TIVA) be the more appropriate anesthetic management for this kind of surgery? This issue is under consideration in this clinical trial.

Multidrug intravenous anesthesia for children undergoing MRI: a comparison with general anesthesia.

Background: We used a multidrug intravenous anesthesia regimen with midazolam, ketamine, and propofol to provide anesthesia for children during magnetic resonance imaging (MRI). This regimen was compared with general anesthesia in a randomized comparative study. Outcome measures were safety, side effects and recovery variables in addition to adverse events in relation to age strata.

Hypobaric bupivacaine spinal anesthesia for cystoscopic intervention: the impact of adding fentanyl.

Background And Objective: Addition of fentanyl to hyperbaric bupivacaine spinal anesthesia prolonged the duration of sensory block. This study seeks to test the hypothesis that adding fentanyl to small dose hypobaric spinal anesthesia will improve intraoperative patients and surgeon satisfaction without delay in recovery.

Methods: Patients (n = 80) subjected to minor cystoscopic surgery were randomly assigned to have spinal anesthesia with either 5 mg bupivacaine 0.
