BACKGROUND Prior studies suggest that obstructive sleep apnea may be associated with gastroesophageal reflux disease, a strong risk factor for Barrett's esophagus. The goals of this pilot case-control study were to determine whether Barrett's esophagus patients have an increased likelihood of obstructive sleep apnea and to determine whether nocturnal gastroesophageal reflux symptoms affect the ...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...

BACKGROUND Barrett's esophagus, a metaplastic precursor to esophageal adenocarcinoma, is becoming increasingly prevalent in many populations. Clinical studies suggest acid reflux causes Barrett's esophagus; however, no population-based estimates of risk have been reported, and the role of other health factors in modifying risk is unclear. METHODS We conducted a population-based case-control s...

The oesophageal adenocarcinoma is an increasing pathology in the last decade, predominantly western population. A characteristic of esophageal cancer (EC) and esophageal-gastric junction (EGJC) high percent metastatic disease at time diagnosis one main causes death these patients. present case about a 78-year-old man, diagnosed with Barrett's esophagus high-grade dysplasia stenosis distal third...

The glutathione S–transferases (GSTs) are a family of enzymes that play an important role in the prevention of cancer by detoxifying numerous potentially carcinogenic compounds. GSTs conjugate reduced glutathione to a variety of electrophilic and hydrophobic compounds, converting them into more soluble, more easily excretable compounds. Decreased glutathione S–transferase-pi (GSTPI) enzyme acti...

OBJECTIVE In the areas where intestinal metaplasia of the stomach is highly prevalent, diagnosing Barrett's esophagus solely by the presence of specialized columnar epithelium in the distal esophagus may lead to many false positive diagnoses. The aim of this study was to test validity of the specialized columnar epithelium as a diagnostic criterion of the short segment Barrett's esophagus in Ko...

BACKGROUND During left atrial (LA) catheter ablation, an atrioesophageal fistula can develop as a result of thermal injury of the esophagus during ablation along the posterior LA. No in vivo studies have examined the relationship of the esophagus to the LA. The purpose of this study was to describe the topographic anatomy of the esophagus and the posterior LA by use of CT. METHODS AND RESULTS...

Several aspects of the biology European eel ( Anguilla anguilla ) larvae are still unknown; particularly, information about their functional development and feeding is sparse. In present study, we histologically characterize digestive system wild caught specimens leptocephalus larvae. The aim was to provide more understanding how food may be ingested mechanically processed in larvae, discuss th...

Adenocarcinoma of the cervical esophagus is a rare tumor, in comparison to adenocarcinoma of the distal esophagus which is on the rise and is often associated with Barrett's esophagus. We present a case of aggressive cervical esophageal adenocarcinoma in a 46-year-old female with no endoscopic or histopathologic evidence of Barrett's esophagus. We discuss the possible etiology of this tumor and...

Mucins secreted by mucus-producing cells are glycoproteins with many important functions such as antimi crobial effect, lubricity and physical barrier. The structure function of mucins may be different in various tissues. Therefore, we designed our study to reveal the current state mucin chemistry glands located partridge's esophagus. esophagus total 10 adult partridges, five female male, whose...
