Background Approximately 10 million people in India suffer from bilateral blindness, with cataracts accounting for roughly 70% of these cases. However, there is a severe scarcity of ophthalmologists in India (12,000 across the country), which makes routine cataract screening very difficult, particularly in rural areas. To tackle this problem, we investigated the use of an artificial intelligence (AI)-based application for cataract screening at All India Institute of Medical Sciences (AIIMS), Bibinagar, that can be used by nursing officers and other healthcare professionals as a primary screening tool.

Article Synopsis
  • The study investigates how cerebral amyloid angiopathy (CAA) affects recovery from ischemic stroke using a 5xFAD mouse model, hypothesizing that amyloid-beta buildup leads to worse outcomes by impairing the blood-brain barrier (BBB).
  • Findings reveal that CAA worsens stroke effects, resulting in narrowed BBB microvessels, decreased cerebral blood flow, and hindered tissue recovery, alongside different gene expression patterns in endothelial cells and neural progenitor cells in the hippocampus.
  • Experiments indicate that disrupting the CXCL12-PIK3C2A-CREB3L2 pathway negatively impacts neurogenesis, but activating the PI3K pathway can restore it

Ebstein's anomaly, a rare congenital heart disease, is distinguished by the failure of embryological delamination of the tricuspid valve leaflets from the underlying primitive right ventricle myocardium. Gaining insight into the genetic basis of Ebstein's anomaly allows a more precise definition of its pathogenesis. In this study, two distinct cohorts from the Chinese Han population were included: a case-control cohort consisting of 82 unrelated cases and 125 controls without cardiac phenotypes and a trio cohort comprising 36 parent-offspring trios.

The complex structure and function of low density lipoprotein receptor (LDLR) makes classification of protein-coding missense variants challenging. Deep generative models, including Evolutionary model of Variant Effect (EVE), Evolutionary Scale Modeling (ESM), and AlphaFold 2 (AF2), have enabled significant progress in the prediction of protein structure and function. ESM and EVE directly estimate the likelihood of a variant sequence but are purely data-driven and challenging to interpret.

The role of natural selection in shaping biological diversity is an area of intense interest in modern biology. To date, studies of positive selection have primarily relied on genomic datasets from contemporary populations, which are susceptible to confounding factors associated with complex and often unknown aspects of population history. In particular, admixture between diverged populations can distort or hide prior selection events in modern genomes, though this process is not explicitly accounted for in most selection studies despite its apparent ubiquity in humans and other species.

Curative treatment for locally advanced esophageal cancer consists of (neo)adjuvant treatment followed by esophagectomy. Both neoadjuvant chemoradiotherapy and perioperative chemotherapy improve the 5-year overall survival rate compared with surgery alone. However, it is unknown whether these treatment strategies are associated with differences in long-term health-related quality of life (HRQL).
