Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

Advanced 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.

Congenital and childhood atrioventricular blocks: pathophysiology and contemporary management [PDF]

, 2016
Atrioventricular block is classified as congeni- tal if diagnosed in utero, at birth, or within the first month of life. The pathophysiological process is believed to be due to immune-mediated injury of the conduction system, which occurs as a result

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...
