The exovesicles (EVs) are involved in pathologic host-parasite immune associations and have been recently used as biomarkers for diagnosis of infectious diseases. The release of EVs by Trypanosoma cruzi, the causative agent of Chagas disease, has recently been described, with different protein cargoes including the MASP multigene family of proteins MASPs are specific to this parasite and charac...

Rabbits, guinea pigs, and chinchillas are all classified as hindgut fermenters, depending on primarily cecal microflora for nutrient composition. The rabbit has some unique anatomical features including the sacculus rotundus and the vermiform appendix. Gastrointestinal disorders in these animals can be a challenge to clinicians as not only the motility of the hindgut must be maintained, but the...

Crohn's disease (CD) is an inflammatory disease of the gastrointestinal tract (GIT) tract and can affect several parts of the digestive system. There is a relationship between impaired mucosal barrier in the GIT of inflammatory bowel disease patients and the role of bacteria such as Mycobacterium avium paratuberculosis in CD. Apart from different therapeutic approaches for treating CD, developm...

Gastroesophageal reflux disease (GERD) is a chronic condition of the digestive system characterized by acidic contents from stomach into esophagus. Surgical treatment offers long-term alternative to medications, providing symptomatic relief and improving quality life in many patients. However, potential risks complications associated with surgery must be considered, careful selection patients c...

the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...

biochemical characteristics of α-amylase in the digestive system and head glands of cryptolaemus montrouzieri, a key predator of citrus mealybug, planococcus citri (pseudococcidae), were studied. the major isoform of α-amylase with the same molecular weight was detected in both gut and head glands loaded on polyacrylamide-starch gel electrophoresis. moreover, a minor band with much lower intens...

Esophageal melanosis which is characterized by melanocytic proliferation in the squamous epithelium of the esophagus and melanin accumulatin of esophageal mucosa (EM) is a rare disease of the digestive system. Although esophageal melanosis is considered to be a benign disease, its etiology is not cleared and has been reported to be the precursor lesion of esophageal primary melanomas. In this r...
