Complex Mosaicism and Aneuploid Cells in Human Embryo Development

Study of Complex Mosaicism in Human Embryos: Revealing Extensive Aneuploidy During Early Embryonic Development Background and Research Objectives Pre-implantation Genetic Testing for Aneuploidy (PGT-A) is a widely used technology in in vitro fertilization (IVF) aimed at screening out abnormal embryos to improve implantation and live birth rates. Ho...

Stem Cell Transplantation Extends the Reproductive Lifespan of Naturally Aging Cynomolgus Monkeys

Stem Cell Transplantation Extends the Reproductive Lifespan of Naturally Aging Cynomolgus Monkeys Background of the Study The ovary is a crucial organ for female reproduction and health, responsible for producing oocytes and secreting sex hormones. As women age, ovarian reserves gradually decline, eventually leading to menopause, which brings about...

Acetyl-CoA Metabolism Maintains Histone Acetylation for Syncytialization of Human Placental Trophoblast Stem Cells

The Role of Acetyl-CoA Metabolism in Maintaining the Synchronization of Human Trophoblast Stem Cells Research Background and Purpose The placenta is a crucial metabolic bridge between the mother and fetus during pregnancy, and its normal function is vital for the health of both. The placenta constantly differentiates through human trophoblast stem ...

Transcriptome Dynamics and Cell Dialogs Between Oocytes and Granulosa Cells in Mouse Follicle Development

Transcriptome Dynamics and Cell Dialogue Between Oocytes and Granulosa Cells During Mouse Follicle Development Overview Follicle development and maturation is a complex, multi-stage process. During this process, dynamic gene expression in oocytes and surrounding somatic cells, as well as the dialogue between them, play crucial roles. This study rev...

A novel protein cytb-187aa encoded by the mitochondrial gene cytb modulates mammalian early development

The New Protein Cytb-187aa Regulates Mammalian Early Development Academic Background Mitochondria are multifunctional organelles that provide energy for cells. In addition to energy supply, they are involved in the regulation of apoptosis, cell signaling, and various biosynthetic pathways. Among these functions, substances within mitochondria can b...

Fetal Brain MRI Abnormalities in Pyruvate Dehydrogenase Complex Deficiency

Abnormalities in Fetal Brain MRI in Pyruvate Dehydrogenase Complex Deficiency Background and Research Objective Pyruvate Dehydrogenase Complex Deficiency (PDCD) is a mitochondrial metabolic disorder caused by pathogenic variants in multiple genes, including PDHA1. Classic neonatal brain imaging features have been described, mainly focusing on devel...

Diagnostic Accuracy of an Integrated AI Tool to Estimate Gestational Age from Blind Ultrasound Sweeps

Diagnostic Accuracy of AI Tools for Estimating Gestational Age Based on Blind Ultrasound Scanning Background Accurate estimation of gestational age (GA) is the foundation of good prenatal care, typically achieved through ultrasound examinations. However, many low-resource areas lack sufficient ultrasound equipment, making accurate GA estimation cha...

Genome, HLA and Polygenic Risk Score Analyses for Prevalent and Persistent Cervical Human Papillomavirus (HPV) Infections

Genome-wide and Polygenic Risk Score Analysis of High-Risk Human Papillomavirus (hrHPV) Infection in the Cervix Background Cervical high-risk human papillomavirus (hrHPV) infection is the second largest carcinogenic infection globally, accounting for approximately 31.4% of all infection-related cancers (about 690,000 cases out of 2.2 million cancer...

Expanding the Phenotype of Copy Number Variations Involving NR0B1 (DAX1)

This study aims to explore the relationship between copy number variations (CNVs) involving the NR0B1 (DAX1) gene and 46,XY gonadal dysgenesis. 46,XY gonadal dysgenesis (GD) is a disorder of sex development caused by the failure of gonads to fully differentiate into testes. This condition can lead to individuals presenting with female or ambiguous ...

Transcutaneous Auricular Vagus Nerve Stimulation Ameliorates Preeclampsia-Induced Apoptosis of Placental Trophoblastic Cells via Inhibiting the Mitochondrial Unfolded Protein Response

Transcutaneous Auricular Vagus Nerve Stimulation Alleviates Preeclampsia-Induced Placental Trophoblast Apoptosis by Inhibiting Mitochondrial Unfolded Protein Response Research Background Preeclampsia is a severe obstetric complication affecting 2%-8% of pregnancies worldwide. This disease not only impacts the health of pregnant women but also serio...
