Parkinson's Disease and Retinal Age Gap: A Cross‐Sectional Analysis

Movement Disorders, EarlyView.
Abstract Background Deep‐learning models are capable of predicting age from retinal scans and the difference between this and chronological age, retinal age gap, has been shown to be significantly associated with risk of mortality, cardiovascular diseases, and kidney failure.

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

VIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...
