Heterotopic gastric mucosa in the gallbladder is an unusual entity and is usually clinically silent. We report a 75-year-old female patient who presented with intermittent upper abdomial pain radiating to the back. Abdominal imaging studies showed a sessile polypoid lesion and a gallstone in the gallbladder. Gallbladder carcinoma was suspected and cholecystectomy performed. Intraoperative froze...

We report on the initial characterization of an elliptically polarized wiggler built by a collaboration between the Advanced Photon Source, the Institute of Nuclear Physics, and the National Synchrotron Light Source. The wiggler has recently been installed in the X13 straight section of the NSLS X-Ray ring. The device consists of a vertical permanent-magnet wiggler and a horizontal electromagne...

classification of occlusion is the first step in diagnosing the relationship between the upper and lower jaw's teeth. based on angle's classification, occlusion is divided into three categories: class i, class ii, and class iii. the aim of this study was to determine the prevalence of occlusion categories, based on angle's classification, in adolescents with permanent dentition in tehran. this ...

Introduction: Delivery by caesarean section (CS) accounts for approximately 32% of all deliveries worldwide, and it may be associated with early late complications. Although postpartum uterine suture necrosis is not a common condition, high morbidity mortality in puerperal women, as well permanent loss fertility these patients. In this article, we present seven patients successfully treated con...

Numbers of caesarean sections, inguinal hernia repairs, and operations for strangulated hernia performed in 1979-81 at 10 rural hospitals in eastern Africa were matched against estimated populations in the respective catchment areas. Annual rates of each operation varied considerably between hospitals, the averages being: for caesarean sections 25 per 100 000 per year; for inguinal hernia repai...

The impact effect is a crucial issue in civil engineering and has received considerable attention for decades. For the first time, this study develops hybrid machine learning models that integrate novel Extreme Gradient Boosting (XGB) model with Particle Swam Optimization (PSO), Grey Wolf Optimizer (GWO), Moth Flame (MFO), Jaya (JA), Multi-Verse (MVO) algorithms predicting permanent transverse ...
