Association of endothelial nitric oxide synthase (NOS3) rs2070744 variant with advanced retinopathy of prematurity: a case-control study and meta-analysis.

Despite advances in neonatal and ophthalmological care, retinopathy of prematurity (ROP) continues to be a leading cause of childhood blindness worldwide. Investigating gene variants associated with vascular responses in ROP may provide valuable insights into its pathogenesis and identify risk or protective factors. Nitric oxide (NO) and endothelin-1 (ET-1) play roles in vascular regulation, influencing processes relevant to ROP development.

Management of Partial-Thickness Rotator Cuff Tears: Biologic and Surgical Interventions.

Partial-thickness rotator cuff tears (PTRCTs) are a common source of shoulder pathology, both in the aging population and in younger overhead athletes. Advanced imaging modalities used currently have led to increases in recognition, diagnosis, and treatment of these tears. The anatomy, five-layer histology, and relationship to the Ellman classification of PTRCTs have been well studied, with recent interest in radiographic predictors, such as the critical shoulder angle and acromial index.

Predictors of Increased Complication Rate Following Tibial Tubercle Osteotomy (TTO).

Purpose: The purpose of the current study was to define the incidence of minor and major complications following TTO at a tertiary-care institution, with determination of predictive factors related to the occurrence of a major complication.

Study Design: Retrospective case series.

Methods: Patients who underwent TTO from 2011 to 2023 were retrospectively identified.

Characterization and Inhibition of the Chaperone Function of Plasmodium falciparum Glucose-Regulated Protein 94 kDa (PfGrp94).

Plasmodium falciparum expresses four heat shock protein 90 (Hsp90) members. Among these, one, glucose-regulated protein 94 (PfGrp94), is localized in the endoplasmic reticulum (ER). Both the cytosolic and ER-based Hsp90s are essential for parasite survival under all growth conditions.
