Current concepts and basic principles of neurogastroenterology in relation to functional gastrointestinal disorders are reviewed. Neurogastroenterology is emphasized as a new and advancing subspecialty of clinical gastroenterology and digestive science. As such, it embraces the investigative sciences dealing with functions, malfunctions, and malformations in the brain and spinal cord, and the s...

Digestive system malignancies are quite common, accounting for 25% of deaths from cancer in the European Union. Various etiological factors of carcinogenesis include hereditary mutations and susceptibility polymorphisms, inflammation due to infectious agents, environmental and dietary factors. Transgenic, knockout or mutant animal models are very useful in reproducing cancers of the digestive t...

Contrast enhanced ultrasonography, using i.v. and/or oral/rectal contrast agents, represents a technical development of the US method, which has proved its applicability in the qualitative and quantitative assessment of the normal and pathological circulatory bed, as well as of the digestive lumen. The use of microbubbles and harmonics opens a new horizon in the detection and characterization o...

In intensive aquaculture, basic studies on fish digestive capacity and metabolism play a key role for diet formulation. In particular, intensive rearing of a new species is strictly related to the development of appropriate nutritional protocols and therefore knowledge of specific features concerning physiology and nutrition is needed. Nutrient utilization by fish is a direct function of the av...

The article presents data on pathomorphological changes of the digestive organs in associative course heterakidosis and histomoniasis turkeys. Changes liver were observed 57.1% cases: protein fatty dystrophy, hepatocyte necrosis. cеcal lesions 100% cases, mainly fibrinous inflammation. In other parts intestinal tract – acute catarrhal

BACKGROUND p53 gene mutations have been reported in over half of all human cancers and they appear to occur in the early stage of cancer, thus indicating the important role that such mutations may play in the carcinogenesis of the digestive tract. This study investigated the differences in p53 abnormalities between cancers of the upper and lower gastrointestinal tract. MATERIALS AND METHODS T...

Recent studies have shown that archaea which were always thought to live under strict anoxic or extreme environmental conditions are also present in cold, oxygenated seawater, soils, the digestive tract of a holothurian deep-sea-deposit feeder, and a marine sponge. In this study, we show, by using PCR-mediated screening in other marine eukaryotes, that marine archaea are also present in the dig...

Background Cancer of the larynx occupies first frequency site cancer upper digestive tract and represents 42% malignant neoplasms aero-digestive tract. It is a potentially curable entity if it diagnosed in early stages. Objective Characterize clinical pathological features patients with laryngeal cancer, which can serve as guide for diagnostic suspicion primary secondary care. Method Descriptiv...
