Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Unusual association of transposition of great arteries with infradiaphragmatic pulmonary venous return

open access: yesAnnals of Pediatric Cardiology, 2020
A 21-day-old baby with transposition of the great arteries with intact ventricular septum, infradiaphragmatic totally anomalous pulmonary venous connection, and atrial septum defect underwent combined arterial switch operation, totally anomalous venous ...

Salvage resection of advanced mediastinal tumors [PDF]

open access: yes, 2019
The surgical treatment of locally advanced mediastinal tumors invading the great vessels and other nearby structures still represent a tricky question, principally due to the technical complexity of the resective phase, the contingent need to carry out

Short and Intermediate Term Outcomes of the Convergent Procedure: Initial Experience in a Tertiary Referral Center [PDF]

open access: yes, 2020
PURPOSE: The Convergent procedure is a hybrid, multidisciplinary treatment for symptomatic atrial fibrillation (AF) consisting of minimally invasive surgical epicardial ablation and percutaneous/catheter endocardial ablation.

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

open access: yesAdvanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.

Pulmonary Vein in a Pinch

open access: yesMethodist DeBakey Cardiovascular Journal
The pulmonary veins normally drain into the left atrium, with the superior pulmonary veins typically situated anterior and inferior to the right pulmonary arteries. However, anomalies can happen.

Abnormal left single pulmonary vein: case report of an anecdotal variant

open access: yesJournal of the Belgian Society of Radiology, 2011
We describe here a patient with a very rare ectopic unilateral single pulmonary vein, with normal distal drainage into the left atrium, and thus a non pathologic finding to be distinguished from clinically significant abnormalities.

Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity [PDF]

open access: yes, 2015
Background Lead V? is routinely analysed due to its large amplitude AF waveform. V? correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V? correlates strongest with left atrial activity.

PRELIVE: A Framework for Predicting Lipid Nanoparticles In Vivo Efficacy and Reducing Reliance on Animal Testing

open access: yesAdvanced Functional Materials, EarlyView.
PREdicting LNP In Vivo Efficacy (PRELIVE) framework enables the prediction of lipid nanoparticle (LNPs) organ‐specific delivery through dual modeling approaches. Composition‐based models using formulation parameters and protein corona‐based models using biological fingerprints both achieve high predictive accuracy across multiple organs.

Partial anomalous pulmonary venous connection in a 72-year-old woman: A case report

open access: yesSAGE Open Medical Case Reports, 2018
Partial Anomalous Pulmonary Venous Connection is a congenital abnormality characterized by drainage of one or more, but not all, pulmonary veins to the right atrium or to one of the systemic veins.
