A study on pulmonary venous ostia pattern in the left atrium and its clinical applications

National Journal of Clinical Anatomy, 2018
Background & aims : Normally four pulmonary veins open into the left atrium. Frequently there are variations in the number of pulmonary veins opening in to the left atrium.

Anomalous single pulmonary venous trunk

Avicenna Journal of Medicine, 2012
We present a rare case of a single pulmonary venous trunk that drains all pulmonary segments to the left atrium. This anomaly may mimic pulmonary arteriovenous malformation on imaging.

Snowman heart

Journal of the Practice of Cardiovascular Sciences, 2019
Total anomalous pulmonary venous connection (TAPVC) consists of abnormality of blood flow in which all pulmonary veins drain into systemic veins or into right atrium with or without pulmonary venous obstruction. Systemic and pulmonary venous blood mix in

A case of left atrial myxoma accompanied by pancytopenia and pathological findings suggestive of pulmonary hypertension

, 1974
A case of left atrial myxoma accompanied by peculiar symptoms is reported. A 15-year old boy had progressive congestive heart failure and three episodes of acute attacks of panctyopenia. The anemia was accompanied by helmet-shaped, broken red blood cells,

Metabolism of asymmetric dimethylarginines is regulated in the lung developmentally and with pulmonary hypertension induced by hypobaric hypoxia

, 2003
Background— Nitric oxide (NO) plays an important part in lowering pulmonary vascular resistance after birth, and in persistent pulmonary hypertension of the newborn (PPHN), NO-mediated dilation is dysfunctional.

Epicardial Connections Between the Pulmonary Veins and Left Atrium: Relevance for Atrial Fibrillation Ablation

, 2011
Epicardial Connections Between PVs and the LA. Introduction: Some observations support the existence of epicardial connections (ECs) between ipsilateral pulmonary veins (vein to vein ECs [VVECs]), and we have observed venoatrial ECs inserted at distance ...

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.
