Overexpression of Renin in the Collecting Duct Causes Elevated Blood Pressure [PDF]
American Journal of Hypertension, 2013 Renin is synthesized in the collecting duct and is regulated differently than renin in the juxtaglomerular apparatus. However, the physiological relevance of collecting duct renin remains unknown, particularly with regard to its ability to regulate blood pressure.We used gene targeting to generate mice with overexpression of renin in the collecting ...

Changes of thoracic duct flow and morphology in an animal model of elevated central venous pressure
Frontiers in Physiology, 2022 Objective: Investigation of lymph fluid dynamics in thoracic duct during central venous pressure elevation.Background: Lymphatic flow is affected by elevated central venous pressure (CVP) in congestive heart failure. The changes of thoracic duct (TD) lymph flow have not been studied chronically in the setting of elevated CVP.

Eosinophilic cholangitis misdiagnosed as cholangiocarcinoma: a case report [PDF]
Frontiers in OncologyEosinophilic cholangitis (EC) has a low clinical incidence, and cases with definitive pathological confirmation are extremely rare. Due to the lack of specificity in clinical and radiologic features, EC is frequently misdiagnosed as cholangiocarcinoma ...

A Sliced Parabolic Equation Method to Characterize Maritime Radio Propagation
Sensors, 2023 For maritime broadband communications, atmospheric ducts can enable beyond line-of-sight communications or cause severe interference. Due to the strong spatial–temporal variability of atmospheric conditions in near-shore areas, atmospheric ducts have ...

A case of eosinophilic cholangitis without bile duct stenosis diagnosed by bile duct biopsy
DEN Open, 2022 Eosinophilic cholangitis (EC) is a rare benign disease that is often misdiagnosed as a malignancy due to the development of biliary stricture. This disease is generally diagnosed by liver biopsy or surgery.
