Octopus vulgaris aquaculture is limited due to poor biological knowledge of the paralarval stages (e.g., digestive system functionality), their nutritional requirements (e.g., adequate live diet) and standardization of rearing techniques. These factors are important in explaining the high mortality rate observed in this developmental stage under culture conditions. For a better understanding of...

Our body is able to make use of the metabolic sources in the environment by way of the alimentary tract. In order for it to serve as a conduit for the food and other essential substances, it has to undergo specific functions such as food propulsion, secretion of digestive juices, and absorption of simplified nutrients and vitamins, among others. Needless to say, any interruptions in the continu...

Introduction Proper functioning of the digestive system is imperative to assimilate nutrients, to sustain essential functions in the human body, to increase the bioavailability of nutrients, to minimize the risk of food intolerances, and to reduce the formation of toxins/irritants in the gastrointestinal-tract. Incomplete digestion often results in digestive problems such as bloating, diarrhea,...

Objective: To analyse the role of various aspects of the Mediterranean diet in several common epithelial cancers, including digestive and selected non-digestive tract neoplasms. Design: Systematic analysis of data from a series of case–control studies. Setting: Northern Italy, between 1983 and 1998. Subjects: Over 12 000 cases of 20 cancer sites and 10 000 controls. Results: For most epithelial...

Laparoscopic radical gastrectomy has been increasingly applied in China. However, how to reduce surgery-related trauma, shorten operative time and achieve the long-term prognosis equal to the conventional open surgery is still hot research topics. Along with the change in learning curve and the optimization of endoscopic techniques, laparoscopic lymph node dissection can achieve or even exceed ...

Metastatic involvement of the heart is a rare occurrence and remains undiagnosed until autopsy. In some instances, patients may have cardiac symptoms, leading to ante-mortem diagnosis. Although most primary cancers have been documented to metastasize to heart, the existing literature on cancers of upper aero-digestive tract is an exception, with only a few reports. We report four cases of upper...

Ultrasound is commonly used in clinical examination which is economic, non-invasive and convenient. Ultrasound can be used for the examination of solid organs and hollow organs. Due to the presence of air, routine ultrasound examination of the digestive tract is not very appropriate, Because of the development of endosonography and its related technology, diagnosis and treatment of gastrointest...

However, the nature by which they work-reducing stomach acid-causes a number of side effects. First, when stomach acid is lowered the gastric mucosa becomes more vulnerable to certain pathogens. Salmonella, for example, is destroyed by stomach acid and lowering the levels of acid could allow this food-borne bacterium to flourish unchecked. Helicobacter pylori, another pathogen common to our dig...

Thyroxine (T4)-prolactin interactions on hepatic arginase and ornithine transcarbamylase (OTC) as well as hind legs, tail, digestive tract and median eminence were investigated in tadpoles, Rana catesbeiana. Prolactin completely blocked T4-induced tail resorption, but failed to suppress hind-leg growth, shortening of digestive tract and promotion by T4 of the median eminence development. Prolac...
