Varying Bifidobacterium species in the maternal-infant gut microbiota correlate with distinct early neurodevelopmental outcomes.

The impact of mother-infant microbiota on neurodevelopment is an area of interest, but longitudinal studies are scarce. Using a cohort of 520 families from the Jiangsu birth cohort in China, we reveal that the maternal gut microbiota during early pregnancy play a substantial role, accounting for 3.34% of the variance in offspring neurodevelopmental scores.

Expression evaluation of exogenous and endogenous alcohol dehydrogenase genes in transgenic s.

A lot of endogenous genes, as well as genes from related species, are transformed back into crops for overexpression to improve their corresponding traits. However, almost all of these transgenic events remain at the testing stage. Most of the singular transgenic events of crops approved for commercial release are developed by the transformation and heterologous expression of exogenous genes from distant species.

Aim: This study investigates the role of autophagy in the pathogenesis of UC in young and elderly patients, and explores the therapeutic potential and mechanisms of autophagy modulators in aged mice with dextran sulfate sodium (DSS)-induced colitis.

Disrupted mitochondrial morphology and function exacerbate inflammation in elderly-onset ulcerative colitis.

Background: The characteristics of ulcerative colitis (UC) in the elderly are quite different from the young population. Mitochondrial injury is a key mechanism regulating both aging and inflammation. This study aims to reveal the role of mitochondrial damage in the pathogenesis of adult- and elderly-onset UC.

The Associations between Breastfeeding and Early Childhood Caries: A Prospective Cohort Study.

Introduction: The association between breastfeeding status and early childhood caries (ECC) remains inconclusive. Few studies evaluate the breastfeeding status including both duration and exclusivity according to the WHO recommendations on breastfeeding. This study aimed to investigate the association between breastfeeding status and ECC.

Risk of comorbidity of autoimmune liver disease in patients with inflammatory bowel disease: A single-center case-control study in China.

Objective: To investigate the prevalence of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC), and the impact of comorbidity of AIH, PBC, and PSC on hospitalization burden in patients with inflammatory bowel disease (IBD).

Methods: Inpatients admitted to Peking Union Medical College Hospital from January 1, 1998 to December 31, 2021 were included. Odds ratio (OR) and the corresponding 95% confidence interval (CI) were calculated to compare the risk of AIH, PBC, and PSC between IBD and non-IBD patients.

S100A11 promotes lipid metabolism and activates the apoptosis in polycystic ovary syndrome.

In Brief: Aberrant lipid metabolism and dysregulated apoptosis in granulosa cells (GCs) may contribute to diminished ovarian reserve in patients with polycystic ovary syndrome (PCOS). This article elucidates the pivotal role played by S100A11.

Abstract: Apoptosis of ovarian GCs affects the development and maturation of oocyte in PCOS.

Comparative study on pregnancy complications: PGT-A vs. IVF-ET with gender-specific outcomes.

The safety and clinical effectiveness of preimplantation genetic testing for aneuploidy (PGT-A) in improving pregnancy outcomes for sub-fertile patients remains controversial. Potential sex-based differences in the relationship between PGT-A and pregnancy complications have not been investigated, which could guide the appropriate clinical application of PGT-A. In this secondary analysis of data from a multicenter, randomized, controlled, non-inferiority trial (NCT03118141), 940 women who achieved singleton live birth during the trial were included to estimate the between-group differences in pregnancy complications following PGT-A versus conventional fertilization (IVF) vary with fetal sex.

Association between iron metabolism and acute kidney injury in cardiac surgery with cardiopulmonary bypass: a retrospective analysis from two datasets.
