UNLABELLED Circulating microRNAs show aberrant expression in patients with cancer. The aim of this study was to investigate the prognostic value of circulating microRNA-21 (miR-21) in digestive system cancers. METHODS All the eligible studies were searched by Medline and EMBASE. The hazard ratios (HRs) for overall survival (OS), which compared the expression levels of circulating miR-21 in pa...

The pathogenesis of digestive disease in poultry involves the cellular events and reactions that result in a deviation from normal structure and function. To a degree, the differentiation of disease and normal in commercial poultry also involves an economic perspective. Factors external to the digestive tract may mimic digestive disease, including reductions in the density of various nutrients ...

We report the case of a 62-year-old woman with a history of liver cirrhosis secondary to autoimmune hepatitis, portal hypertension and coagulopathy. Gastroscopy was performed to discard esophageal varices. In the gastric antrum a multiple polypoid and polylobed lesions were observed, occupying prepyloric region and extending into the pylorus and duodenal bulb (Fig. 1). Ultrasonography was perfo...

Pharmaceutical name: Bulbus Alli Sativi (da suan) Botanical name: Allium sativum Daily dose: 6-15g or 3-5 cloves in decoction, or added to the diet; raw garlic is more effective than cooked or dried forms. Notes: In 100 cases of amebic dysentery, a strong decoction of garlic was curative in 88% of the cases. Bulbs with purple skin were found to be more effective in this clinical study than thos...

The digestive system of any animal is important in converting the food the animal eats into the nutrients its body needs for growth, maintenance, and production (such as egg production). An animal's body breaks down food through both mechanical and chemical means. In many animals, mechanical action involves chewing; however, because birds do not have teeth, their bodies use other mechanical act...

Understanding an animal’s nutritional niche is fundamental to a full appreciation of its ecology , and is important for both pest control and species conservation purposes. Carnivores have digestive systems dominated by the small intestine , which can be related to the generally high digestibility of their food. Omnivores have more complex gastrointestinal tracts , with a hindgut caecum in whic...

Cathepsins are lysosomal peptidases belonging to the papain family, and based on their catalytic sites, these enzymes can be divided into serine, cysteine and aspartic proteases. The studies conducted to date have identified, 15 types of cathepsins that are widely distributed in intracellular and extracellular spaces. These proteases participate in various pathological activities, including the...
