Recent developments in the epidemiology, staging, and treatment of esophageal and gastroesophageal junction cancers have led to significant changes in the way these malignancies are managed. Although a relationship between gastroesophageal reflux disease and esophageal cancer has been demonstrated, antireflux surgery has been shown to have no preventive effect with regard to the development of ...

Vesicoureteral reflux (VUR) is the most common anomaly associated with duplex systems. In addition to an uncomplicated duplex system, reflux can also be secondary in the presence of an ectopic ureterocele with duplex systems. Controversy exists in regard to the initial and most definitive management of these anomalies when they coexist. This paper will highlight what is currently known about du...

AIMS To examine the relation between colic and feeding difficulties and their impact on parental functioning for a primarily clinic referred sample. METHODS Forty three infants (and their mothers) were enrolled between 6 and 8 weeks of age. Infants were divided into two groups, colic (n = 19) and comparison (n = 24), based on a modified Wessel rule of three criteria for colic. Families were a...

S ince its introduction in 1974, ambulatory oesophageal pH monitoring has secured a valuable but complementary role in the diagnosis of gastro-oesophageal reflux disease. Monitoring of oesophageal pH allows not only the detection of excessive levels of acid exposure but also, and more importantly, assessment of the relationship between acid reflux and symptoms. It is especially useful for clari...

Introduction: Gastro-esophageal reflux disease (GERD) is present when repeated backflow of gastric contents into the esophagus causes chronic symptoms or damages the esophageal lining. In recent years, the prevalence of GERD has increased and there is a strong correlation between acid reflux and the increasing incidence of esophageal cancer [1]. The gastro-esophageal junction (GEJ) is the key d...

Non-erosive reflux disease (NERD) is the most common presentation of gastroesophageal reflux disease. Although acid reflux is the most important cause of symptom generation in NERD patients, non-acid reflux is also associated with reflux symptoms. The temporal relation between symptoms and reflux episodes is of importance in evaluating the results of combined pH-impedance monitoring in NERD pat...

Various porous binary oxides with elevated textural properties were obtained in this work. The as-synthesized solids were calcined or modified by reflux and extraction processes. Characterizations through SEM, nitrogen physisorption and TEM techniques demonstrated the formation of porous metal oxide networks over all solids. XRD, thermal analyses and FTIR measurements showed the existence of na...

a modified f-expansion method to find the exact traveling wave solutions of  two-component nonlinear partial differential equations (nlpdes) is discussed. we use this method to construct many new solutions to the nonlinear whitham-broer-kaup system (1+1)-dimensional. the solutions obtained include jacobi elliptic periodic wave solutions which exactly degenerate to the soliton solutions, triangu...

The mechanical force relationships that distinguish normal from chronic reflux at sphincter opening are poorly understood and difficult to measure in vivo. Our aim was to apply physics-based computer simulations to determine mechanical pathogenesis of gastroesophageal reflux. A mathematical model of the gastroesophageal segment (GES) was developed, incorporating the primary anatomical and physi...

Abstract Hydrogen peroxide electric pump supply system can provide an improvement to hybrid rocket motor performance. Due the physical and chemical properties of hydrogen peroxide, a canned scheme is more suitable be used in motor. The high-temperature liquid between rotor stator pump, returning inlet inducer, has considerable influence on anti-cavitation numerical simulation results show that ...
