Interaction among ET-1, endothelium-derived nitric oxide, and prostacyclin in pulmonary arteries and veins

, 1994
Endothelin-1 causes vasodilation of the intact porcine pulmonary vascular bed. To determine the cause of this vasodilation, we investigated the interactions of endothelin-1 (ET-1), endothelium-derived nitric oxide (EDNO), and prostacyclin in isolated ...

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Pulmonary venous abnormalities encountered on pre-radiofrequency ablation mapping multidetector computed tomography

South African Journal of Radiology, 2017
Multidetector computed tomography (MDCT) elegantly renders pulmonary venous anatomy. With increasing numbers of radiofrequency ablation procedures being performed, there is now a greater emphasis on pre-procedure imaging to delineate this anatomy ...

Scalable Engineering of Bio‐Manufactured Extracellular Vesicles for Selective Delivery in Ovarian Cancer Patient‐Derived Models

Advanced Science, EarlyView.
Engineered extracellular vesicles displaying Ephrin‐B2 selectively target Ephrin‐B4–expressing ovarian cancer cells, enabling precise delivery in patient‐derived models. This scalable bio‐manufacturing platform reveals a versatile strategy to exploit Ephrin signaling for highly specific therapeutic payload delivery and motivates exploration of tailored

Congenially absent pulmonary veins -diagnostic pitfalls two case reports

, 1996
Two patients with partial absence of the right and left pulmonary veins respectively are described. Congenitally absent pulmonary veins are a rare phenomenon and the diagnosis is often missed or delayed.

NET‐DNA Activates the ANXA2/TMEM215/BiP Axis to Promote Mitophagy‐Mediated Anoikis Resistance in Endometriosis

Advanced Science, EarlyView.
NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...

Comment to: Acute and chronic consequences of polidocanol foam injection in the lung in experimental animals by Grandi L, Grandi RA, Tomasi CD, da Rocha JL, Cardoso V, Dal-Pizzol F. Phlebology 2013;28:441-4.

Veins and Lymphatics, 2014
To assess the occurrence of pulmonary embolism and long-term inflammatory activation after polidocanol foam injection, domestic rabbits, of both sexes, weighing around 2 kg were used: a control group (injection of saline solution, n = 4) and an ...

Developmental differences in endothelium-dependent responses in isolated ovine pulmonary arteries and veins

, 1993
Despite evidence for an important role for endothelium-derived relaxing factor (EDRF) in transitional circulation, previous in vitro studies of newborn pulmonary arteries have demonstrated diminished EDRF activity when compared with arteries from older ...

Heterojunction‐Engineered Mass Spectrometry Platform for Deciphering Serum Metabolic Fingerprints in Diagnosis of Respiratory Diseases

Advanced Science, EarlyView.
Hollow Co3O4/TiO2 heterojunctions are engineered for high‐throughput laser desorption/ionization mass spectrometry. The built‐in electric field drives efficient charge separation and photothermal conversion, while the hierarchical mesoporous network enables robust salt and protein tolerance.

Cardiac and smooth muscle cell contribution to the formation of the mouse pulmonary veins

, 2000
Previous studies have demonstrated that the primordial pulmonary veins originate as an outgrowth of the atrial cells and anastomosis with the pulmonary venous plexus.
