the main inflammatory bowel disorders are including celiac disease (cd), inflammatory bowel diseases (ibd) and irritable bowel syndrome (ibs). celiac disease is a digestive and autoimmune disorder that can damage the small intestine and characterized by a multitude gastrointestinal (gi) and extra gi symptoms. ibd (including ulcerative colitis and crohn’s disease) is a group of inflammatory cond...

background: in view of high prevalence of gi cancers in lorestan province, western iran, and a large number of esophageal cancer patients in this region, this study was done to determine the frequency of various gi cancers in the area. â  methods: in a cross-sectional study, all patients from lorestan province for whom endoscoppy and colonoscopy were performed and biopsy was provided entered ou...

gastrointestinal (gi) diseases affect a large number of people all over the world. uncontrolled acid secretion and occurrence of gastric ulcers are common disorders of gi tract which pose serious problems to human health. many synthetic drugs have been used to treat gi disorders but a definite cure has not been discovered so far and the available medications cause several side effects. nigella ...

We consider the evolution of a population of fixed size with no selection. The number of generations G to reach the first common ancestor evolves in time. This evolution can be described by a simple Markov process which allows one to calculate several characteristics of the time dependence of G. We also study how G is correlated to the genetic diversity.

Recent explorations of the oldest known rocks of marine sedimentary origin from the southwestern coast of Greenland suggest that they preserve a biogeochemical record of early life. On the basis of the age of these rocks, the emergence of the biosphere appears to overlap with a period of intense global bombardment. This finding could also be consistent with evidence from molecular biology that ...

Previous analyses have shown that the most recent common ancestor for a randomly mating population of size n would have lived approximately log 2 n generations ago; for example, a panmictic population of one million people would have a common ancestor about 20 generations in the past. Structured populations consisting of panmictic subpopulations connected by migration at frequencies as low as o...

BACKGROUND The clinical manifestations of celiac disease (CD) have changed in the past decades. There are currently little data describing the initial clinical manifestations of CD in children in Iran. This study describes the initial presentation of children with suspected CD from a geographically defined region in Iran. METHOD Medical records of children seen in 2007 - 2015 from Sistan and ...

Each day, the typical healthcare practice is challenged by several cases involving gastrointestinal (GI) complaints. Moreover, many conditions in which symptoms are not localized to the GI but may be systemic often involve an underlying GI dysfunction. For example, research has shown associations between compromised GI function and conditions as varied as rheumatoid arthritis, asthma, metabolic...
