Intussusception may occur anywhere in the gastrointestinal system. Unlike its idiopathic childhood counterpart, it is uncommon during adult life and a definitive cause is usually found; almost half of cases develop with malignancy. Gastrointestinal stromal tumors (GIST) originate from interstitial Cajal cells of the gastrointestinal tract. They more frequently occur in the stomach and small int...

the aim of the present study was to determine the presence of helicobacter species in different parts of gastrointestinal tract, hepatobiliary system and pancreas of stray cats. six different sites at the level of genus, gastric (h. heilmannii and h. felis) and enterohepatic species of helicobacter were investigated in six cats using species-specific primers by polymerase chain reaction (pcr). ...

Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubili...

An outbreak of a lethal disease was reported in 4–6-month-old Holstein calves in a feedlot around Tehran. The signs of central nervous system and gastrointestinal system (GI) involvement were observed in the diseased animals. Necropsy samples of GI, liver, kidney, spleen and lung from 3 died animals were prepared for histopathological examination. Blood and formalin-fixed ear notch samples of 6...

inflammatory myofibroblastic tumor (imt) is a rare neoplastic lesion with tendency toward local aggressive behavior and recurrence. the tumor most commonly occurs in the pulmonary system of children and young adult, although it may rarely develop in older patients and other organs. symptoms are non-specific and depend on the location of the tumor. the gastrointestinal tract is rarely the primar...

background gastrointestinal stromal tumors (gist) are the most common mesenchymal tumors of the gastrointestinal (gi) tract. they are usually c-kit positive and seen slightly more common in men. these tumors are seen in the gi tract from the esophagus to the anus with occasional invasion or metastasis. method in this retrospective study, we evaluated the prevalence of c-kit positive stromal tum...

there is documented evidence that infection in laboratory animals can often influence the outcome of experiments. all infections, apparent or inapparent, are likely to increase biological variability. as a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...

vancomycin-resistant enterococci (vre) are becoming a major concern in medical practice. their increased prevalence and their ability to transfer vancomycin resistance to other bacteria have made them a subject of close scrutiny and intense investigation. colonization is usually acquired by susceptible hosts in an environment with a high rate of patient colonization with vre. the aim of this st...

BACKGROUND & OBJECTIVES Information on gastrointestinal manifestations and then response after curative parathyroid surgery is scarce in symptomatic primary hyperparathyroidism (PHPT). This study was carried out to analyse gastrointestinal manifestations in patients with PHPT and their associations with biochemical parameters. METHODS This retrospective study included 153 patients with sympto...
