Genetically engineered human pluripotent stem cells (hPSCs) have been proposed as a source for transplantation therapies and are rapidly becoming valuable tools for human disease modeling. However, many applications are limited due to the lack of robust differentiation paradigms that allow for the isolation of defined functional tissues. Here, using an endogenous LGR5-GFP reporter, we derived a...
Anticancer drugs have been reported to damage the intestinal mucosa. We evaluated the effects of caloric intake on the mucosal morphology and immune cells in rats treated with 5-fluorouracil (5-FU). Rats were received a liquid diet plus 5-FU treatment for 8 days as follows: Low calorie group (25 kcal/day with 5-FU), Normal calorie group (50 kcal/day with 5-FU), and Control group (50 kcal/day wi...
campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...
The gastrointestinal (GI) tract represents a complex ecosystem in which a balance exists between the intestinal microflora and the host. The microflora comprises predominantly of facultative anaerobes e.g. lactobacillus and obligate anaerobes e.g. bifidobacterium. Aerobic organisms are not present in the GI tract of healthy individuals except Pseudomonas in very small numbers. Most of the gut m...
Female mammals produce milk to feed their newborn offspring before teeth develop and permit the consumption of solid food. Intestinal enterocytes dramatically alter their biochemical signature during the suckling-to-weaning transition. The transcriptional repressor Blimp1 is strongly expressed in immature enterocytes in utero, but these are gradually replaced by Blimp1(-) crypt-derived adult en...
the aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. in this study, 450 day-old female broiler chickens (arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. on day 14 of the experiment,...
Intestinal duplication in an adult is an uncommon congenital abnormality because only minority of cases present in adulthood. More than 80% of cases occur before the age of two years as an acute abdomen, bowel obstruction or other complications associated with it. Duplication has two types, either cystic or tubular. Here, we report a case of an adult who was diagnosed preoperatively on CT scan ...
To evaluate the effects of endotoxin on the morphology of the equine mesenteric vasculature, each of two thoroughbred horses were given two intravenous injections (24 h apart) of a sublethal dose of endotoxin (10 microg/kg). Each injection produced results similar to those of clinical cases of equine colic with obstructive nature of the loop of bowel: diarrhoea within 2 h after administration, ...
Intestinal explants are a useful model for toxicological and pathological studies, but the maintenance of tissue viability for longer periods of incubation remains challenging. The aim of this study was to evaluate the effect of age on the viability of intestinal explants. Jejunal explants were obtained from 24and 42-day-old piglets. The explants were incubated for two or four hours and were th...
