Hydroxychloroquine enhances insulin sensitivity and ameliorates abnormal lipid metabolism in obese women with polycystic ovary syndrome.

Background: Hydroxychloroquine (HCQ) is frequently utilized in rheumatic immune disorders and has been discovered to exert hypoglycemic effects in some obese women with polycystic ovary syndrome(PCOS), however, the precise efficacy and mechanism of action remain ambiguous.

Objective: To examine the impact of HCQ on glucose and lipid metabolism as well as sex hormone levels in obese women with PCOS.

Method: Fifty obese women with PCOS were randomly allocated into two groups: HCQ group (n = 25) and metformin (MET) group (n = 25).

Mismatch prime editing gRNA increased efficiency and reduced indels.

Prime editing enables precise and efficient genome editing, but its efficacy is hindered by pegRNA's 3' extension, forming secondary structures due to high complementarity with the protospacer. The continuous presence of the prime editing system also leads to unintended indel formation, raising safety concerns for therapeutic applications. To address these challenges, we develop a mismatched pegRNA (mpegRNA) strategy that introduces mismatched bases into the pegRNA protospacer, reducing complementarity and secondary structure formation, and preventing sustained activity.

Co-precipitation fabrication of cellulose/chitosan-aniline grafted composites for efficient removal of Pb ions from aqueous solution.

Heavy metal ions, are non-biodegradable, high toxic tendency, and have serious hazardous effects on the health of humans. Then, removing them from the environment using different techniques is necessary. Several routes are expensive, low-efficient, and require a long time to achieve adsorption equilibrium.

Association of Metabolomics With Incidence of Age-Related Macular Degeneration: The UK Biobank Study.

Purpose: The purpose of this study was to identify serum metabolites associated with age-related macular degeneration (AMD) incidence and investigate whether metabolite profiles enhance AMD risk prediction.

Methods: In a prospective cohort study involving 240,317 UK Biobank participants, we assessed the associations of 168 metabolites with AMD incidence using Cox hazards models. Principal component analysis (PCA) captured 90% of the variance in metabolites.

TRIM59/RBPJ positive feedback circuit confers gemcitabine resistance in pancreatic cancer by activating the Notch signaling pathway.

Pancreatic cancer (PC) is one of the most lethal malignant tumors that lacks effective treatment, and gemcitabine-based chemoresistance occurs frequently. Therefore, new therapeutic strategies for PC are urgently needed. Tripartite motif containing 59 (TRIM59) plays an important role in breast and lung cancer chemoresistance.
