Genes for childhood myopia.

Myopia is associated with interactive effects of genetic and environmental factors. The development of myopia in childhood is likely to be more dependent on genetic background. Candidate gene analysis, whole exome sequencing, genome-wide association studies (GWAS) and subsequent metaanalyses have identified more than 400 loci that are associated with myopia.

Low clinical activity score, 'progressive' thyroid eye disease: presentations of 1439 patients from a tertiary centre in Hong Kong.

Background: To report the presenting clinical, serological and treatment profiles of 1439 patients with thyroid eye disease (TED) from a tertiary centre in Hong Kong.

Study Populations: Consecutive patients with TED presented to the Thyroid Eye Clinic (TEC), the Chinese University of Hong Kong between 2014 and 2023.

Methods: Prospective cohort and masked review of medical records and orbital images.

Fabrication of ZrO Armor Ceramics by 3D Printing Accompanied with Microwave Sintering.

Ceramic armor protection with complex shapes is limited by the difficult molding or machining processing, and 3D printing technology provides a feasible method for complex-shaped ceramics. In this study, ZrO ceramics were manufactured by 3D printing accompanied with microwave sintering. In 3D printing, the formula of photosensitive resin was optimized by controlling the content of polyurethane acrylic (PUA) as oligomer, and the photosensitive resin with 50% PUA showed excellent curing performance with a small volume shrinkage of 4.

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.
