Consumption of hookahs, e-cigarettes, and classic cigarettes and the impact on medically assisted reproduction treatment

Scientific Reports
Smoking of classic cigarettes has been well-established as a health risk factor, including cardiovascular, neurological, and pulmonary diseases. Adverse effects on human reproduction have also been shown. Smokers are assumed to have a significantly lower

The Critical Role of Enhanced OXPHOS and Mitochondrial Hyperpolarization in Simulated Microgravity‐Induced Oocyte Maturation Arrest

Advanced Science, EarlyView.
Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

Double versus single blastocyst biopsy and vitrification in preimplantation genetic testing (PGT) cycles: protocol for a systematic review and meta-analysis of clinical and neonatal outcomes

Systematic Reviews
Background The number of re-biopsied blastocysts is widely increasing in IVF cycles and concerns regarding retesting, which involves double biopsy and vitrification-warming, have been raised.

EETs Reduction Contributes to Granulosa Cell Senescence and Endometriosis‐Associated Infertility via the PI3K/AKT/mTOR Signaling Pathway

Advanced Science, EarlyView.
1) 14, 15‐EET levels were decreased in ovarian granulosa cells, follicular fluid, peritoneal fluid from endometriosis patients. 2) EETs reduction in endometriosis follicular fluid aggravated granulosa cell senescence. 3) ROS reduced 14, 15‐EET levels by upregulating EPHX2 through a mechanism involving histone methylation modification.

Engineering Decavalent, Sperm‐Binding Laminin‐IgG Hybrid Antibodies for Potent Non‐Hormonal Contraception

Advanced Science, EarlyView.
This study investigates a highly multivalent mAb platform fusing Laminin‐511 heterotrimerization domains with Fabs and IgG1‐Fc as a non‐hormonal contraceptive. The most potent molecule ‘LamH10’, possessing 10 Fabs, rapidly achieved >99% reduction in progressively motile sperm at just 33µg per dose in sheep, making the laminin‐IgG hybrid platform the ...

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

Advanced Science, EarlyView.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

Advanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

m6A Reader hnRNPA2B1 Modulates Late Pachytene Progression in Male Meiosis Through Post‐Transcriptional Control

Advanced Science, EarlyView.
As an m6A reader, hnRNPA2B1 predominantly regulates specific transcripts (e.g., Ep400, Rrs1) that are essential for chromosome organization and remodeling in an m6A‐dependent manner. Furthermore, it is demonstrated to interact with factors involved in mRNA processing and translation. This dual functionality is pivotal for ensuring the proper occurrence
