Introduction: Irritable bowel syndrome (IBS) is one of the most common diseases affecting people around world. It characterized by irregular movements and abdominal pain. IBS significantly reduces quality life patients. Despite such a frequent occurrence this disease, its correct diagnosis treatment still causes many problems for primary care physicians. Aim study: The aim study to present curr...

BACKGROUND AND AIMS Assessing the presence and degree of intestinal inflammation objectively, simply, and reliably is a significant problem in gastroenterology. We assessed faecal excretion of calprotectin, a stable neutrophil specific marker, as an index of intestinal inflammation and its potential use as a screening test to discriminate between patients with Crohn's disease and those with irr...

BACKGROUND Blastocystosis is a frequent bowel disease. We planned to to evaluate the prevalence of Blastocystis spp. in patients who applied to the same internal medicine-gastroenterology clinic with or without gastrointestinal complaints to reveal the association of this parasite with diagnosed IBS and IBD. METHODS A total of 2334 patients with gastrointestinal symptoms composed the study gr...

This controlled study compared the strength and porosity of 48 polymethylmethacrylate cement-implant constructs prepared with open bowl versus vacuum mix technique. Forty-eight blast finished stainless steel rods of 13 mm diameter were implanted with centralizers into 17-mm inner diameter tubes that had been retrograde filled with polymethylmethacrylate cement. The eight cement preparations use...

LINK Background & Aims: Rectal pain sensitivity has been called a biological marker for irritable bowel syndrome, but this conclusion may be premature. This article is a critical review of the evidence for psychological influences on perception. Methods: The world literature accessible through Index Medicus from 1973 to 1997 was systematically reviewed. Results: Evidence favoring a biological b...

in this case report we will describe a rare association between anhyrotic ectodermal dysplasia (aed) and immunodeficiency and autoimmunity [in our case: idiopathic thrombocytopenic purpura (itp) and crohn disease]. aed is a rare congenital disorder characterized by sparse hair, abnormal teeth and anhidrosis due to lack of eccrine glands. the survey of 87 cases with (aed) revealed only one irrit...

A bowl-shaped nitrogen-doped nanographene composed of a pyrrolo[3,2-b]pyrrole core substituted with six arene rings circularly bonded one another undergoes bowl-to-bowl inversion low barrier. This resembles that an umbrella flipped by the strong wind. The transition state is not planar, but possesses rather twisted, S-shaped conformation Ci symmetry. bowl-inversion mechanism follows quadruple-w...

Bowl-in-bowl stacking of buckybowls on a copper surface is observed via scanning tunneling microscopy (STM) at low temperatures and characterized by density functional theory (DFT) calculations.

The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solut...
