introduction: vanadium salts have been suggested as a possible therapeutic agent for the treatment of diabetes. the aim of the present study was to clarify immunohistochemical changes that occur in the pancreatic beta ([pancreatic islet beta]) cells of vanadyl sulphate (vs) treated stz induced diabetic rats. materials and methods: male wistar rats were made diabetic with injecting a single intr...

the histological analysis, disposition and histochemical localization of tryptophan were investigated in the pancreas to compare the cellular organization and histochemical characterization in the pancreas of labeo rohita (hamilton, 1822), mystus vittatus (bloch, 1790) and notopterus notopterus (pallas, 1769) having different feeding habits. histological analysis demonstrated that the exocrine ...

histomorphologic and histomorphometric studies on the pancreas of mehraban male sheep were done in four age groups: fetus, neonate, young adult and old age in this respect, we used special stainings, light microscope and ocular micrometer. the results showed that the smooth muscles were absent in capsule. the tubular portion of exocrine pancreas was more prominent. neuroinsular complex and beta...

Ischemia-driven islet isolation procedure is one of the limiting causes pancreatic transplantation. Ischemia-reperfusion process associated with endothelium dysfunction and release pro-senescent microvesicles. We investigated whether endothelial microvesicles prompt senescence in vitro. Pancreatic islets were isolated from male young rats. Replicative was induced by serial passaging primary por...

Background: Pancreatic cancer‐associated diabetes mellitus (PC‐DM) is present in most patients with pancreatic cancer, but its pathogenesis remains poorly understood. Therefore, we aimed to characterize tumor infiltration Langerhans islets cancer and determine clinical relevance. Methods: islet invasion was systematically analyzed 68 ductal adenocarcinoma (PDAC) using histopathological examinat...

Pancreatic and duodenal homeobox-1 (PDX-1) is a transcription factor that regulates insulin expression and islet maintenance in the adult pancreas. Our recent studies demonstrate that PDX-1 is an oncogene for pancreatic cancer and is overexpressed in pancreatic cancer. The purpose of this study was to demonstrate that PDX-1 is a therapeutic target for both hormonal symptoms and tumor volume in ...

abstract men-i is a rare genetic disorder classically characterized by a predisposition to tumors of the parathyroid glands, anterior pituitary gland, and pancreatic islet cells. we present a case of men-i syndrome diagnosed using predominantly nuclear medicine imaging followed by radionuclide therapy, thus emphasizing the role of nuclear imaging in diagnosing and treating men-i.
