introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...

Intussusception, invagination of a segment the gut into an adjacent one, is relatively common cause intestinal obstruction in children but very rare and uncommon clinical entity adults accounting to 1% near about 65% these are caused by malignant lead point. The Lipomatous polyp accounts for 4% all benign tumors gut. In most cases, seen particularly large intestine, usually sub mucosal around i...

background and objectives: the etiology, pathophysiology, nomenclature and clinical manifes-tation of solitary rectal ulcer syndrome (srus) is poorly understood. aim: to examine the pathology of mucosal changes and clinical features of this syndrome. materials and methods: the mucosal biopsies of 19 patients with clinical evidence of solitary rectal ulcer as been reviewed in accordance with the...

We examined the effects of an intensive fixture schedule on salivary IgA (SIgA) concentration in professional soccer players from the English Premier League. Salivary samples were obtained from 21 males who participated in seven games over a 30-day period during December 2013 and January 2014 (games 1-5 occurred in a 15-day period). Salivary-IgA decreased (P < 0.05) at 2 days post-game 3 (45 ± ...

Mucosal immunity in mammals is mediated mainly by secretory immunoglobulin A (SIgA), which is produced by IgA plasma cells commonly located in the lamina propria, and a transport system involving the polymeric Ig receptor (pIgR). In teleost fish, IgM plays some roles associated with mucosal defence. Very recent findings indicate that IgT, an antibody exclusive to teleosts, might have a special ...

general, any n-sequence determines a multiset of (= n!/k!(n-k)!) k-sequences. "J Suppose, conversely, that we are given a multiset 01 k-sequences. Does that multiset come from some sequence? If so, is the source sequence unique? Such questions are reminiscent of the problem of reconstructing graphs from vertex-deleted sub raphs, which has received a great deal of attention in the last twent yea...
