Purpose: To eva1uate US, CT and endoscopic retrograde pancreatography (ERP) findings ofintrad ucta1 mucin-hypersecreting neop1asm (IMHN). MateriaJs and Methods : We categorized an IMHN as be10nging to a group of disease that can be clinica11y detected by the pooling ofmucus prod uced by tumors inside the main duct or branch ducts ofthe pancreas, thus causing di1atation ofthese ducts. We retrosp...

A proper set of models are carefully selected from the literatures to form a wholistic perspective in simulating the wave propagation in evaporation ducts, under a close-to-realistic environment. The split-step Fourier (SSF) propagation algorithm is applied to analyze the propagation properties in evaporation ducts above a rough sea surface, with turbulence in the ducts. The scattering effect o...

The aim of the study was to evaluate the intrahepatic ramification of hepatic veins and biliary ducts in American mink liver. Minks are not classical laboratory animals, but with the expansion of fur farming these animals have become available for many biomedical researches. Hepatic veins and biliary ducts of the mink liver were studied by dissection and injection corrosion technique. We determ...

INTRODUCTION The lesions of the salivary ducts may be idiopathic, post- traumatic, or iatrogenic and lead to sialocele formation with persistent painful facial swelling or cutaneous fistula formation. No consensus on treatment of this condition exists: the options of treatment include needle aspiration, pressure dressings, antisialogogue therapy, radiotherapy, botulinum toxin and surgical appro...

We employed immunocytochemical and in situ hybridization techniques to study the expression of transforming growth factor beta 1 (TGF-beta 1) in rat submandibular gland. Immunoreactivity for TGF-beta 1 was observed in the cells of granular convoluted tubules (GCTs), striated ducts, and excretory ducts, whereas it was absent in the intercalated ducts and secretory acini in both male and female r...

Heating, ventilation, and air conditioning (HVAC) ducts in buildings behave as multimode waveguides when excited at radio frequencies and thus, can be used to distribute radio signals. The channel properties of the ducts are different from the properties of a usual indoor propagation channel. In this paper, we describe physical mechanisms which affect the HVAC channel impulse response and analy...

Vents with louvers are an important component in the indoor heating, ventilation, and air conditioning (HVAC) system providing a degree of freedom to occupants direct flow prevent foreign objects from entering or exiting ducts. As result, whether designing ventilation any duct design that involves louvers, influence louver cannot be ignored. For vent design, aside angle, blockage ratio is facto...

It will be seen that the largest group of cases occurs in the first two decades. There is a fall in the 20 year group followed by a high level after the age of 30 years. It is noticeable that whereas males predominate under the age of 20 females are greatly in excess after 30 years. Rose (1954), in his analysis of a rather larger group of mixed cases, also drew attention to the preponderance of...

Intrahepatic cholangiocarcinoma (iCCA) can originate from the large bile duct group (segment ducts and area ducts), small (septal interlobular terminal (bile ductules canals of Hering) intrahepatic biliary tree, which be histopathological corresponding to type iCCA, iCCA with ductal plate malformation pattern, cholangiolocarcinoma, respectively. The challenge in pathological diagnosis above sub...

Mammalian sex determination involves complex interacting networks of cellular and hormonal signals leading to the development of male or female phenotypes. Three main sequential processes are involved: first, the establishment of chromosomal sex at fecundation (genetic sex); second, the development of the undifferentiated gonad into either testes or ovaries (gonadal sex); and third, differentia...
