Background: Both antimüllerian hormone and body mass index are associated with the pregnancy outcomes in women with polycystic ovary syndrome undergoing in vitro fertilization.
Objective: This study aimed to explore the effect of different combinations of antimüllerian hormone and body mass index on pregnancy outcomes in women with polycystic ovary syndrome undergoing in vitro fertilization.
Study Design: This was a post hoc secondary analysis of a multicenter randomized trial. A total of 625 women from 1 center with antimüllerian hormone levels measured before in vitro fertilization treatment were classified into 6 groups: group A (normal weight and low antimüllerian hormone group), group B (normal weight and intermediate antimüllerian hormone group), group C (normal weight and high antimüllerian hormone group), group D (overweight/obese and low antimüllerian hormone group), group E (overweight/obese and intermediate antimüllerian hormone group), and group F (overweight/obese and high antimüllerian hormone group).
Results: After adjustment via multivariate logistic regression, the overweight/obese and high antimüllerian hormone group (group F) had a higher risk of clinical pregnancy miscarriage (adjusted odds ratio, 3.30; 95% confidence interval, 1.35-8.07) than the normal weight and intermediate antimüllerian hormone group (group B). Both the normal weight and high antimüllerian hormone group (group C; adjusted odds ratio, 3.74; 95% confidence interval, 1.06-13.24) and the overweight/obese and high antimüllerian hormone group (group F; adjusted odds ratio, 3.61; 95% confidence interval, 1.05-12.38) had higher risks of ovarian hyperstimulation syndrome than the normal weight and intermediate antimüllerian hormone group (group B).
Conclusion: In women with polycystic ovary syndrome, high serum antimüllerian hormone levels were associated with an increased risk of clinical pregnancy miscarriage in women who were overweight/obese but not in those with normal weight.

Nuclear receptors (NRs) are a superfamily of ligand-activated transcription factors that regulate gene expression in response to metabolic, hormonal, and environmental signals. These receptors play a critical role in metabolic homeostasis, inflammation, immune function, and disease pathogenesis, positioning them as key therapeutic targets. This review explores the mechanistic roles of NRs such as PPARs, FXR, LXR, and thyroid hormone receptors (THRs) in regulating lipid and glucose metabolism, energy expenditure, cardiovascular health, and neurodegeneration.

Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

Diurnal floret opening and closure (DFOC) is essential for rice reproductive development and hybrid breeding, yet transcriptional dynamics and underlying regulatory networks remain poorly characterized. Here, we conducted high-temporal-resolution transcriptomic analyses of lodicules to dissect DFOC regulatory networks in two japonica rice cultivars. Analysis of differentially expressed genes (DEGs) uncovered core genes shared by both cultivars, primarily associated with jasmonic acid (JA) signaling and cell wall remodeling.

Purpose: To assess the intra-individual variability of serum progesterone (P) levels on embryo transfer (ET) day, when the same dose of intramuscular progesterone (IM-P) was used in two consecutive hormone replacement therapy (HRT) frozen embryo transfer (FET) cycles.
Methods: A total of 75 patients undergoing two consecutive HRT-FET cycles in one year performed at Bahceci Ankara IVF Center between November 2019 and February 2022 were retrospectively analyzed. Serum P levels were measured at the 117th-119th hours of support by a single laboratory.
