    Abstract : Melatonin is recognised as the pineal hormone regulating sleep and circadian rhythm. It has also been identified in peripheral tissues (mainly in animals) and thought to display a variety of actions, including anti-inflammatory properties, regulation of gastrointestinal (GI) functions, glucose homeostasis and beneficial effects in different tumour types.

    Abstract : Background: Gastrointestinal symptoms such as dyspepsia, diarrhoea, and nausea are often seen in alcoholics. The causes are not clear. The stomach and upper small intestine are exposed to high alcohol concentrations. READ MORE

  5. 3. The significance of low-grade inflammation in the gastrointestinal tract

    Abstract : BackgroundGastrointestinal (GI) symptoms are commonly reported in a normal population. Mostly, the symptoms are of benign cause but occasionally the symptoms can be signs of a more harmful disease. In general, it is difficult to distinguish whether the reported symptoms are caused by a benign (functional) or organic (i.e. READ MORE

  7. 5. An experimental study on the interaction between the neuro-endocrine and immune systems in the gastrointestinal tract

    Abstract : The mucosa lining of the gastrointestinal (GI) tract is in immediate contact with food nutrients to allow a rapid and efficient digestion and absorption and at the same time protects against the incessant risk of attack from pathogenic microbes. Maintenance of normal physiological activities in the GI tract is dependent on a number of regulatory interactions between the nervous, endocrine, and immune systems, as well as environmental and genetic factors.
