Effects of Endogenous Androgens on Pulmonary Microvascular Reactivity

, 2007
Previous studies involving large isolated pulmonary arteries have suggested that the administration of high concentrations of natural androgen produces acute vasodilation. This study examines the acute effects of testosterone (T) and dihydrotestosterone (

Double-Stranded RNA Attenuates the Barrier Function of Human Pulmonary Artery Endothelial Cells

, 2013
Circulating RNA may result from excessive cell damage or acute viral infection and can interact with vascular endothelial cells. Despite the obvious clinical implications associated with the presence of circulating RNA, its pathological effects on ...

Tetrastigma Hemsleyanum Polysaccharide Suppresses Triple‐Negative Breast Cancer by Disrupting the Hippo‐YAP/TEAD4‐PDIA4 Axis and Endoplasmic Reticulum Stress Adaptation

Advanced Science, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...

An infant with primary pulmonary vein stenosis, associated with fatal occlusion of intraparenchymal small pulmonary veins

, 2014
Primary pulmonary vein stenosis (PVS) is rare within the pediatric population and its pathophysiology remains unclear, especially as to how the histopathology relates to its refractoriness to treatment.

A network of pulmonary vein thrombi is a risk factor for ischemic stroke, especially after cardiac surgery: A case report and mini review

International Journal of Cardiology: Heart & Vasculature, 2015
Stroke remains a devastating complication following cardiac surgery. Pulmonary vein thrombi (PVT) are believed to be rare, but I have reported 37 cases of PVT in elderly patients with chest pain since 2012, indicating that PVT are not unusual.

The Pathobiology of Chronic Thromboembolic Pulmonary Hypertension

, 2016
Chronic thromboembolic pulmonary hypertension (CTEPH) is a late sequel of venous thromboembolism that cannot be completely reproduced in animal models. The prevalence of CTEPH in humans is estimated at roughly 17-20 per million; however, partly because ...

TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

Advanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Endothelin-1 focally constricts pulmonary veins in rats

, 1995
Serum endothelin levels increase during sepsis, ischemia, reperfusion, pulmonary operations, and systemic hypertension after surgery. Despite extensive study, the site and extent of action of endothelin on the pulmonary microcirculation are not well ...
