Gut microbiota–bile acid‐vitamin D axis plays an important role in determining oocyte quality and embryonic development

open access: yesClinical and Translational Medicine, 2023
Objective To reveal whether gut microbiota and their metabolites are correlated with oocyte quality decline caused by circadian rhythm disruption, and to search possible approaches for improving oocyte quality.

Grtp1 Safeguards Against Paternal Reproductive Aging and Intergenerational Behavioral Deficits by Preserving Redox Homeostasis

open access: yesAdvanced Science, EarlyView.
This study identifies that Grtp1 maintains germline redox homeostasis by interacting with PRDX1/4‐TXN to antagonize paternal reproductive aging. Growth hormone restores Grtp1 expression, rectifies aberrant sperm DNA methylation, and ameliorates intergenerational anxiety and social deficits, highlighting the GH‐GRTP1 axis as a promising intervention ...

Impact of ovarian stimulation duration in GnRH antagonist protocols on the cumulative ongoing pregnancy rate in women with normal ovarian reserve: a cohort study

open access: yesReproductive Biology and Endocrinology
Background The optimal duration of ovarian stimulation in GnRH antagonist protocols remains insufficiently explored, despite its potential impact on oocyte quality, embryo development, and endometrial receptivity.

Fertility Preservation in Hypogonadal Men

open access: yes, 2017
Increasing numbers of men in the United States are seeking treatment for symptomatic hypogonadism with testosterone supplementation therapy (TST). In addition, the use of anabolic-androgenic steroids (AAS) is also increasing. Our current knowledge of the

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

open access: yesAdvanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

Integration of transcriptomics and metabolomics reveals the mechanism of Lycium barbarum polysaccharides inhibited MCF-7 cell proliferation

open access: yesScientific Reports
Breast cancer, as a highly prevalent malignant tumor among women, has a consistently high mortality rate due to metastasis and drug resistance. Lycium barbarum polysaccharides (LBP), which have been reported to have significant anti-tumor activity, have ...

TECTB Variants Reveal Tectorial Membrane Vulnerability in Dominant Non‐Syndromic Hearing Loss

open access: yesAdvanced Science, EarlyView.
TECTB is a non‐collagenous protein of the tectorial membrane – an extracellular matrix of the cochlea. This study identifies dominant missense variants in TECTB linked to human hereditary deafness in two unrelated families. Genetically engineered mice homozygous for one of the variants are profoundly deaf, whereas heterozygous mice have normal hearing ...

Colossal Magnetic‐Field‐Induced Anomalous Hall Conductivity in a Kagome Antiferromagnet YMn6Sn6

open access: yesAdvanced Science, EarlyView.
Magnetic‐field‐driven spin canting in the kagome antiferromagnet YMn6Sn6${\rm YMn}_6{\rm Sn}_6$ reshapes flat and Dirac bands near the Fermi level, redistributing Berry curvature and producing colossal anomalous Hall conductivity. The study reveals how magnetic configuration and clean‐limit skew scattering cooperate to amplify Hall transport, offering ...

scGEN: Leveraging an Adaptive Weighting Strategy for Challenging Cell Clustering in Single‐Cell RNA‐seq

open access: yesAdvanced Science, EarlyView.
scGEN combines attribute–structure encoding, adaptive hard‐sample weighting, and regularized zero‐inflated negative binomial loss to resolve ambiguous single‐cell states. In the developing human pituitary, refined annotations reveal Pre.Gonado cells at 7 weeks and previously obscured developmental communication networks.

Global Burden and Temporal Trends of Early‐Onset Tracheal, Bronchial, and Lung Cancer: An Analysis of GLOBOCAN 2022 and GBD 2023 Data

open access: yesAdvanced Science, EarlyView.
This study systematically assessed the global burden and temporal trends of EOTBL cancer in individuals aged 15–49 years. Smoking, ambient particulate matter pollution, and secondhand smoke remain dominant risk factors. Countries within the same Human Development Index (HDI) category exhibit distinct epidemiological trajectories, underscoring the need ...
