background plasmablastic lymphoma (pbl) is a relatively new entity, classified by who as a rare variant of diffuse large b cell lymphoma. the present case report introduces a 17 year old girl with chronic diarrhea, abdominal pain, intra-abdominal venous thromboses, ascites, mesenteric lymphadenopathies and small intestinal polyposis, the pathologic and immunohistochemistric examinations of the ...

Looping of the initially straight embryonic gut tube is an essential aspect of intestinal morphogenesis, permitting proper placement of the lengthy small intestine within the confines of the body cavity. The formation of intestinal loops is highly stereotyped within a given species and results from differential-growth-driven mechanical buckling of the gut tube as it elongates against the constr...

an experiment was conducted under completely randomized design to study the effect of different levels of probiotic biomin imbo (0.0, 0.05, 0.1, 0.15 per cent) in starter, (0.0, 0.025, 0.05, 0.075 per cent) in grower and (0.0, 0.0125, 0.025, 0.0375 per cent) in finisher diets on morphology of digestive system and immuno system of broiler chicks for 49 days. 400 day old chicks (mixed male and fe...

The Drosophila hindgut develops three morphologically distinct regions along its anteroposterior axis: small intestine, large intestine and rectum. Single-cell rings of 'boundary cells' delimit the large intestine from the small intestine at the anterior, and the rectum at the posterior. The large intestine also forms distinct dorsal and ventral regions; these are separated by two single-cell r...

I . Rates of disappearance of glucose from ligated loops of small intestine in lambs, adult sheep and young rats were studied. The concentration of glucose in the lumen decreased exponentially with time, suggesting that within a range of concentrations of 166-277 m-moles/l glucose was absorbed mainly by passive diffusion. 2. The rate of absorption of glucose from a 166 mM-solution based on eith...

Three species of Calliobothrium inhabit the spiral intestine of Mustelus schmitti in Argentina and Uruguay. Calliobothrium verticillatum australis is redescribed and its taxonomic status modified to species as C. australis. Calliobothrium barbarae n. sp. can be distinguished from all other species of Calliobothrium, which are small bodied, nonlaciniate, and without accessory piece between the b...
