DNA Nanoflower LYTACs Enable Efficient VEGF Degradation and Verteporfin Loading for Combined Therapy of Wet Age‐Related Macular Degeneration

Advanced Science, EarlyView.
An integrated approach that combines a DNA nanoflower VEGF degrader with photodynamic therapy is developed for the treatment of wet age‐related macular degeneration, which reduces the risk of VEGF reactivation‐induced CNV recurrence and minimizes the systemic side effects associated with photodynamic therapy.

Islet Amyloid Polypeptide Modelled to Simulate Diabetes Co‐Oligomerized with β‐Amyloid 1‐42 Reproducing the Pathological Cascade of Alzheimer's Disease in Human Cerebral Organoids

Advanced Science, EarlyView.
Human islet amyloid polypeptide (hIAPP) was used to mimic T2DM, and Aβ42‐hIAPP co‐oligomers were delivered into the human mature cerebral organoids (COs), which reproduce typical AD pathology and significant neuronal death more closely resembling that of AD patients.

A rare case of dynamic left ventricular outflow tract obstruction caused by systolic anterior motion of an abnormal posterior mitral leaflet

IHJ Cardiovascular Case Reports, 2018
Dynamic obstruction to left ventricular outflow in patients with hypertrophic cardiomyopathy usually occurs when the anterior mitral leaflet moves forward in systole and approaches or contacts the ventricular septum.

Curvy Surface Reconstruction

Advanced Science, EarlyView.
This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...

A Small Molecule Inhibitor of Sarcomere Contractility Acutely Relieves Left Ventricular Outflow Tract Obstruction in Feline Hypertrophic Cardiomyopathy

PLoS ONE, 2016
Hypertrophic cardiomyopathy (HCM) is an inherited disease of the heart muscle characterized by otherwise unexplained thickening of the left ventricle. Left ventricular outflow tract (LVOT) obstruction is present in approximately two-thirds of patients ...

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

Advanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...
