Association between 25(OH) vitamin D and schizophrenia: shared genetic correlation, pleiotropy, and causality.

Background: This study delves into the complex interplay between genetics, 25-hydroxyvitamin D (25OHD), and schizophrenia (SCZ). It leverages extensive sample data derived from Genome-Wide Association Studies (GWAS) to uncover genetic correlations.

Methods: Employing Linkage Disequilibrium Score Regression (LDSC) and S-LDSC, this study investigates genetic connections between 25OHD and SCZ.

Association between 25(OH) vitamin D and multiple sclerosis: cohort, shared genetics, and Causality.

Background: Multiple Sclerosis (MS), an autoimmune disorder causing demyelination and neurological damage, has been linked to 25-hydroxyvitamin D (25OHD) levels, suggesting its role in immune response and MS onset. This study used GWAS datasets to investigate genetic associations between 25OHD and MS.

Methods: We utilized a large-scale prospective cohort to evaluate serum 25OHD levels and MS risk.

Developmental and reproductive response of Brachmia macroscopa (Lepidoptera: Gelechiidae) to three host plants.

The sweet potato leaf folder, Brachmia macroscopa Meyrick (Lepidoptera: Gelechiidae), which is a significant pest of plants in the family Convolvulaceae, is rapidly expanding its range in South China and other subtropical regions. Studies were designed to examine the effects of three different host plants (sweet potato, Ipomoea batatas (L.) Lam.

Temperature effects on development and fecundity of Brachmia macroscopa (Lepidoptera: Gelechiidae).

The current study investigated the impacts of temperature on the development and reproductivity of the sweet potato leaf folder, Brachmia macroscopa (Lepidoptera: Gelechiidae), in sweet potato leaves under laboratory conditions. We determined developmental time of B. macroscopa larval, pupal, and pre-adult stage at different temperatures.
