Article Synopsis
  • The study investigates the link between novel NOBOX gene variants and a specific infertility issue known as oocyte, zygote, and embryo maturation arrest (OZEMA) in women.
  • Researchers found two different NOBOX variants in women undergoing IVF, one associated with oocyte maturation arrest and the other with embryonic developmental arrest.
  • The findings suggest that NOBOX variants may influence not only primary ovarian insufficiency but also the later stages of oocyte and embryo development, indicating its crucial role in female fertility.

Biphasic IVM can be offered as a patient-friendly alternative to conventional ovarian stimulation in IVF patients predicted to be hyper-responsive to ovarian stimulation. However, cumulative live birth rates after IVM per cycle are lower than after conventional ovarian stimulation for IVF. In different animal species, supplementation of IVM media with oocyte-secreted factors (OSFs) improves oocyte developmental competence through the expression of pro-ovulatory genes in cumulus cells.

Background: Cognitive deterioration is common in multiple sclerosis (MS) and requires regular follow-up. Currently, cognitive status is measured in clinical practice using paper-and-pencil tests, which are both time-consuming and costly. Remote monitoring of cognitive status could offer a solution because previous studies on telemedicine tools have proved its feasibility and acceptance among people with MS.

The interplay between mitochondrial DNA genotypes, female infertility, ovarian response, and mutagenesis in oocytes.

Hum Reprod Open

December 2024

Vrije Universiteit Brussel (VUB), Brussels Health Campus/Faculty of Medicine and Pharmacy, Research Group Genetics, Reproduction and Development , Laarbeeklaan 103, 1090 Brussels, Belgium.

Study Question: Is there an association between different mitochondrial DNA (mtDNA) genotypes and female infertility or ovarian response, and is the appearance of variants in the oocytes favored by medically assisted reproduction (MAR) techniques?

Summary Answer: Ovarian response was negatively associated with global non-synonymous protein-coding homoplasmic variants but positively associated with haplogroup K; the number of oocytes retrieved in a cycle correlates with the number of heteroplasmic variants in the oocytes, principally with variants located in the hypervariable (HV) region and rRNA loci, as well as non-synonymous protein-coding variants.

What Is Known Already: Several genes have been shown to be positively associated with infertility, and there is growing concern that MAR may facilitate the transmission of these harmful variants to offspring, thereby passing on infertility. The potential role of mtDNA variants in these two perspectives remains poorly understood.

Structural, architectural, contractile, or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodelling has become a cornerstone diagnostic and prognostic marker. The structure and the function of the LA and left atrial appendage (LAA), which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation, cardioembolism, heart failure, and mitral valve diseases.
