Quercetin Enhances 5-Fluorouracil-Driven Cytotoxicity Dose-Dependently in A375 Human Melanoma Cells.

Cutaneous melanoma (CM) represents a severe skin cancer with a rising incidence at present and limited treatment options. 5-Fluorouracil (5-FU) is widely used, including for CM; however, the innate resistance of this cancer to conventional therapy remains problematic. Quercetin (QUE) is a flavonoid that can sensitize cancer cells to antitumor agents such as 5-FU.

Retinal Degeneration Associated With Biallelic RDH12 Variants: Longitudinal Evaluation of Retinal Structure and Visual Function in Pediatric Patients.

Purpose: The purpose of this study was to determine the natural history of the photoreceptor disease in a large group of pediatric patients with RHD12-associated Leber congenital amaurosis (RDH12-LCA), to estimate the changes expected over the duration of a clinical trial, and to define the relationship between the photoreceptor loss and visual dysfunction.

Methods: Forty-six patients representing 36 families were included. The great majority of patients were under the age of 18 years.

Myelinated Glial Cells: Their Proposed Role in Waste Clearance and Neurodegeneration in Arachnid and Human Brain.

One of the most important goals in biomedical sciences is understanding the causal mechanisms of neurodegeneration. A prevalent hypothesis relates to impaired waste clearance mechanisms from the brain due to reported waste aggregation in the brains of Alzheimer patients, including amyloid-β plaques and neurofibrillary tau tangles. Currently, our understanding of the mechanisms by which waste is removed from the brain is only fragmentary.

The effectiveness of ultrasound-indicated cerclage for the reduction of extreme preterm birth in twin pregnancies with a short cervix: a systematic review and meta-analysis.

Objective: This study aimed to evaluate the effectiveness of cervical cerclage in women with a twin pregnancy and a midpregnancy asymptomatic short cervix (≤25 mm), in preventing preterm birth and improving neonatal outcomes.

Data Sources: Systematic searches were conducted in MEDLINE, Embase, Web of Science, Scopus, and Cochrane Library up to April 17, 2023, updated in September and February 2024.

Study Eligibility Criteria: Included were randomized controlled trials, cohort studies, and case-control studies comparing cerclage with expectant management in twin pregnancies and an asymptomatic short cervix (≤25 mm).

Management of Cervical Cerclage after Premature Preterm Rupture of Membranes: An argument for retention: Retention vs Removal of Cerclage after Premature Preterm Rupture of Membranes.

Preterm birth remains the leading cause of infant morbidity and mortality worldwide. Efforts aimed at reducing preterm birth rates have largely focused on mitigating risks in those who have already experienced a preterm delivery. One intervention, the placement of a cervical cerclage, has been shown to reduce the risk of subsequent preterm delivery in the appropriate candidate.
