colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. we report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with ...

To obtain information on the concentration and spectrum of bile acids in human cecal content, samples were obtained from 19 persons who had died an unnatural death from causes such as trauma, homicide, suicide, or drug overdose. Bile acid concentration was measured via an enzymatic assay for 3alpha-hydroxy bile acids; bile acid classes were determined by electrospray ionization mass spectrometr...

BACKGROUND Chronic diarrhoea is the clinical hallmark of patients presenting with idiopathic bile acid malabsorption. Its pathogenesis is unknown; colonic water secretion can be induced by dihydroxy bile acids, but it is not known whether enrichment of the bile acid pool with these bile acids occurs in such patients. Furthermore, bile acid malabsorption is known to affect biliary lipid composit...

abstract autoimmune pancreatitis (aip) is a rare disorder that may be present as common bile duct stricture. the patient was a seventy-year-old man with presentations as recurrent abdominal pain and jaundice, elevated billirobin (bil) and elevated alkaline phosphatase (alkp) in association with the presence of hetrogenesity of the pancreatic head and dilated intra and extra hepatic bile ducts i...

The mechanism of cholestasis (decreased bile flow) induced by taurolithocholate in the isolated perfused hamster liver was investigated. Taurocholate was infused to maintain bile acid output, and sulfobromophthalein (BSP) was administered to establish a BSP transport maximum in bile. The effects of taurolithocholate on bile flow and on the biliary secretion of BSP and bile acid anions were dete...

BACKGROUND The human body has simple and compound organs that obtain their nourishment through four humors. One of them is bile (yellow bile). According to Iranian traditional medicine (ITM), there are various kinds of natural medicines with their specific mechanisms of action affecting on bile in the human body. Hakim Aghili Shirazi (18th century), one of the great scholars in ITM field, intro...

1. Enzymes, proteins, glycoproteins and lipids of rodent bile were compared with those of a plasma-membrane subfraction originating from the hepatocyte bile-canalicular membrane. 2. Three bile-canalicular glycoprotein enzyme activities were detected in bile. Comparison of the pH optimum and immunoinhibition properties of membrane and bile 5'-nucleotidase activity indicated that they were the sa...

In this paper, we revisit Donald Schön’s scholarly work on “handling uncertainty”, suggesting that in order to cope reasonably well with uncertainty, practitioners should be encouraged to take a reflective existential stance, aimed to explore their own tacit personal style (i.e., theories-in-use). They should (i) recall and reflect on their theories-in-use to bear on the phenomenon, (ii) metaph...
