bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

Neonates cannot concentrate their urine to the same degree as adults. One of the key factors in concentrating the urine is the renal collecting duct osmotic water permeability (Pf) response to antidiuretic hormone (ADH). Neonatal cortical collecting ducts have a blunted Pf response to ADH compared with adult tubules (Pf: 119.0 +/- 12.5 vs. 260.1 +/- 29.5 microm/s, P < 0.05). We found that the p...

Monoclonal antibodies to Å“il surface markers of human exo crine pancreas were used to establish the cytotypic expression of cells forming "tubular complexes" in pancreases from six adults without carcinoma and in the nontumorous pancreatic parenchyma of 16 pancreases with carcinoma. These cells man ifested duct cell determinants. In general, the presence of cells with duct cell surface markers...

Monoclonal antibodies to cell surface markers of human exocrine pancreas were used to establish the cytotypic expression of cells forming "tubular complexes" in pancreases from six adults without carcinoma and in the nontumorous pancreatic parenchyma of 16 pancreases with carcinoma. These cells manifested duct cell determinants. In general, the presence of cells with duct cell surface markers w...

Using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. Use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. In this work two-dimensional incompressible laminar flow of a nanofluid e...

biliary papillomatosis is a disorder characterized by numerous adenomatous polyps of variable distribution and extent in intrahepatic bile ducts. it should be considered as a premalignant condition because a high proportion of the lesions undergo malignant transformation. in this report, we present a patient with abdominal pain and jaundice. according to his presenting signs and symptoms, ercp ...

intraductal papillary mucinous neoplasms (ipmns) are rare pancreatic tumours, accounting for less of 1-2% of all neoplasms of the gland. main characteristics of ipmns are their favourable prognosis as these pre-malignant or frankly malignant lesions are usually slow-growing tumours and radical surgery is frequently possible. according with the localization of the lesions, three different entiti...

developmental midline perinasal masses in children are rare lesions specifically in association with choristomas. we encountered a 3-year-old boy with epiphora, a striking mass on the nasal bridge and ipsilateral nasal hypoplasia. ct scan imaging showed multiple calcified areas within the tumor in addition to linear defect in frontal bone, hypoplastic left ethmoidal sinus and left nasal cavity,...
