Müllerian duct abnormalities consist of a set of structural malformations that include diverse situations of agenesis or aplasia, which may evolve according to three distinct patterns: a failure of the paramesonephric ducts (Müllerian ducts) to develop in the whole or in part (uterus unicornis and segmental aplasia of uterine horn, respectively), the failure of caudal part of the paramesonephri...

Clonorchiasis is caused by a chronic infestation of liver flukes, Clonorchis sinensis, and these reside mainly in the medium- and small-sized intrahepatic bile ducts. Therefore, diffuse, uniform, minimal or mild dilatation of these bile ducts, particularly in the periphery, without dilatation of the extrahepatic bile duct is the typical finding on several imaging modalities. We report here on t...

Hilar cholangiocarcinomas involving the bifurcation of the hepatic duct are called Klatskin tumors. A resected specimen of the hilar hepatic region with Klatskin tumor was analyzed. The lining epithelium of major biliary ducts was regular, while the majority of epithelial cells lining the excretory ducts of peribiliary glands (PBGs) exhibited malignant features. The connective tissue surroundin...

Article Direct cholangioscopy has been possible since the 1970’s (1) but reliable intubation of the common bile duct (CBD) and second order ducts has limited the applicability of the technique. One of the limitations to accessing the ducts is the acute angulation between the duodenum and the CBD (2). Various methods have been employed to access the ducts including mother-and-baby endoscopes and...

objective: to study the morphology ofgonads and sperm ducts of sex reversed male rainbow trout after administration of i 7-cr- methyl testosterone. animals: rainbow trout, oncorhynchus mykiss. procedure: l7-alpha-methyl testosterone (17-alpha-mt) was administered to rainbow trout in 5 treafinents as follows: i) rwo times immersion of eyed eggs and yolk sac alevins in 250 pg/l bath with 2 hours ...

The accumulation of essential oils in Angelica archangelica subsp. archangelica roots at different developmental stages was investigated through histochemical and chemical analyses. Roots less than 1 mm in diameter showed a primary diarch structure and two primary secretory ducts in the pericycle. These ducts were ephemeral and probably became dysfunctional early on. Oil accumulation was observ...

BACKGROUND Intraductal and invasive adenocarcinoma of duct of Luschka is rare. To the best of our knowledge, this is the second case report of intraductal and invasive carcinoma arising from ducts of Luschka. CASE PRESENTATION Patient presented to hospital with signs and symptoms of chronic cholecystitis and cholelithiasis. Ultrasound examination revealed thickening of gallbladder wall with a...

Concentrations of delta 4 androstenedione, testosterone and dihydrotestosterone were measured in the post-nuclear supernatant of the dog epididymis. In addition, they were measured in the efferent ducts and the testis. From the efferent ducts to the corpus there was a significant decrease in testosterone and delta 4 androstenedione concentrations. On the contrary, the concentration of dihydrote...
