BACKGROUND Increased duodenal intraepithelial lymphocytes is a key histological finding in celiac disease. Available studies suggest a wide normal range (10 - 40 intraepithelial lymphocytes /100 epithelial cells, EC). We assessed the normal range of distal duodenal intraepithelial lymphocytes. METHODS Biopsies from the normal-looking distal duodenum from individuals referring for endoscopy fo...

OBJECTIVE Systemic amyloidosis is a rare disorder, characterized by extracellular accumulation of Congo red positive fibrillar amyloid protein deposits that have an amorphous, eosinophilic appearance on hematoxylin-eosin stained preparations. The kidney is the most commonly affected organ by systemic amyloidosis. Congo red staining increases the positive birefringence of the weakly birefringent...

Real-time on-site histopathology review of biopsy tissues at the point-of-procedure has great potential for significant clinical value and improved patient care. For instance, on-site review can aid in rapid screening of diagnostic biopsies to reduce false-negative results, or in quantitative assessment of biospecimen quality to increase the efficacy of downstream laboratory and histopathology ...

background: nail disorders comprise approximately 10% of all dermatological conditions. abnormalities in the color of nails are called ungal dyschromia or chromonychia. ungual dyschromia may be endogenous or exogenous. yellow discoloration of the nails has been reported during the last years as separate observation related to drug administration, during hemodialysis and associated with pulmonar...

inclusion body hepatitis (ibh) has been reported in many countries in the world. the ibh or similar cases characterized by hepatitis and presence of intra-nuclear inclusion bodies in hepatocytes have not been reported in broiler chickens in iran. this is the first report on outbreak of adenovirus-like inclusion body hepatitis in iran. on october 2012, an onset of high acute mortality in a flock...

We study models of electrodeposition of hybrid organic-inorganic films with a special focus on the growth of ZnO with eosin Y. First we propose a rate equation model which assumes that the organic additives form branches with an exposed part above the ZnO deposit, growing with larger rate than the pure film and producing ZnO at the exposed length. This accounts for the generation of OH − ions f...
