Probiotics are viable defined microorganisms (bacteria or yeasts) that exert a beneficial effect on the health of the host when ingested in adequate amounts. Screening for such biotherapeutic agents is commonly performed by in vitro assays simulating gastrointestinal environment to determine the ability to survive in the digestive tract. In the present study, the possibility of extrapolation of...

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). ...

In the present study, an attempt has been made to assess the probiotic characteristics of lactobacilli and yeast strains isolated from whey beverage under conditions simulating the in vivo stresses encountered in the gastrointestinal tract i.e. acid, alkaline, proteolytic enzymes and bile stress. The therapeutic potential of probiotics Lactobacillus casei or Lactobacillus yoghurt was assessed i...

Accidental ingestion or inhalation of foreign bodies has been widely documented, including incidents which occur whilst undertaking dental treatment. Most ingested objects pass through the gastrointestinal tract (GIT) spontaneously, but approximately 10%-20% need to be removed endoscopically and 1% require surgery. This case reports a complication arising from the accidental loss of an archwire...

Although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (GI) melanoma has been reported in rare cases. In this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(NF1). Both cases showed no evidence of any lesions in skin and eye. Malignant melanoma of GI tract...

prediction of the outcome and severity of acute upper gastrointestinal bleeding (ugib) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. recent international recommendations endorse using scoring systems for management of non-variceal ugib patients. to date, different scoring systems have been developed for predicting the risk of 30-day mo...

background: cancer has a high mortality rate in both developing and developed countries. 11%–15% of cancers are attributable to occupational risk factors. objective: to determine if specific occupational classes, based on the international standard for classification of occupations 2008 (isco-08), are risk factors for gastrointestinal (gi) cancer. methods: in this case-control study, 834 cancer...
