Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

open access: yesAdvanced Science, EarlyView.
This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Quadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis

open access: yesThe Turkish Journal of Pediatrics, 2008
Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy.

Aortic valve disease [PDF]

open access: yesInternational Journal of Clinical Practice, 2014
Aortic valve disease is common and has significant impact on prognosis and quality of life. In this educational review, we cover the pathophysiology, presentation and assessment of aortic stenosis (AS) and aortic regurgitation (AR), including the role of imaging modalities beyond echocardiography.

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Leucine‐Dependent SLC7A5–PGAM5 Interaction Promotes Advanced Atherosclerosis Through Hindering Mitochondrial Function of Macrophages

open access: yesAdvanced Science, EarlyView.
Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,

Patient-specific image-based computer simulation for theprediction of valve morphology and calcium displacement after TAVI with the Medtronic CoreValve and the Edwards SAPIEN valve [PDF]

open access: yes, 2016
AIMS: Our aim was to validate patient-specific software integrating baseline anatomy and biomechanical properties of both the aortic root and valve for the prediction of valve morphology and aortic leaflet calcium displacement after TAVI.
