1. The Duodenal Mucosal Bicarbonate Secretion : Role of Melatonin in Neurohumoral Control and Cellular Signaling
Abstract : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. READ MORE

2. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin
Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired. READ MORE

3. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility
Abstract : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. READ MORE

4. Effects of Orexins, Guanylins and Feeding on Duodenal Bicarbonate Secretion and Enterocyte Intracellular Signaling
Abstract : The duodenal epithelium secretes bicarbonate ions and this is regarded as the primary defence mechanism against the acid discharged from the stomach. For an efficient protection, the duodenum must also function as a sensory organ identifying luminal factors. READ MORE

5. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology
Abstract : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. READ MORE
