Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Large Broadening of the Superconducting Transition by Fluctuations in a 3D Metal at High Magnetic Fields: The MgB$_{2}$ case

, 2004
It is shown that the transition to the low temperature superconducting state in a 3D metal at high magnetic field is smeared dramatically by thermal fluctuation of the superconducting order parameter.

Endometrial Assembloid Model Reveals Endometrial Gland Development Regulation by Estradiol‐Driven WNT7B Suppression

Advanced Science, EarlyView.
This study developed a 3D endometrial assembloid model to study how uterine glands form and develop. They discovered key interactions between different cell types and identified WNT7B as a regulator controlled by estradiol‐mediated TGFβ1‐VDR interaction.

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.
