Duct-to-Duct Biliary Reconstructions and Complications in 100 Living Donor Liver Transplantation
Background. The biliary complications in duct-to-duct biliary reconstruction of right or left lobe living-donor liver transplantation (LDLT) have been reported various in incidence up to 40 %. And that could result in serious morbidity or mortality to the recipient’s. We evaluated the risk factors …

Effects of duct source and termination impedance on the acoustic response characteristics of duct elements
… is to study the effects of termination of an air duct on the acoustic response characteristics of the elements in the duct system. The end reflections due to the mis-match of the acoustic impedance at the termination affect the acoustic characteristics of the duct elements; The ducts of the duct …

Genetic Regulation of Müllerian Duct Regression
… progenitor tissues for both male and female reproductive tract organs before they fully differentiate into a male or female tract. The progenitor tissue for the male reproductive tract is known as the Wolffian duct (WD), and the progenitor tissue for the female reproductive tract is the Müllerian …

MACHINE LEARNING APPROACH FOR EVAPORATION DUCT NOWCAST
The Evaporation Duct Height (EDH) and Strength (EDS) are properties of the evaporation duct that affects electromagnetic (EM) signal propagation close to the air-sea interface. Hence, the accuracies of EDH and EDS affect radar and communication propagation, which can be exploited for detection and …

Factors affecting recurrence of intrahepatic duct stone and factors affecting development of cholangiocarcinoma after initial treatment of intrahepatic duct stone
Background Hepatolithiasis causes recurrent cholangitis, biliary cirrhosis, and is an important risk factor for cholangiocarcinoma, which has a grave prognosis. Nevertheless, its intractable nature and high recurrence rate complicates treatment. Therefore, we investigated factors affecting …

The role of Wt1 in Müllerian duct development
… where we deleted <em>Wt1</em> in the Müllerian duct (MD) mesenchyme using a novel conditional null reporter allele, <em>Wt1 flox-RFP</em>. This allele utilizes the Cre-lox system to delete exons 8 and 9 of <em>Wt1</em>, disrupting the DNA binding capability of the protein. Simultaneously, a …
