HLA-G MOLECULES: FROM EMBRYO IMPLANTATION TO OOCYTE MATURATION [PDF]
, 2009 Background Assisted reproduction technique (ART) pregnancy rates have not changed in recent years and an increased risk of twins, triplets or higher order pregnancies leads to a perinatal mortality and morbidity.

FEBS Open Bio, EarlyView.The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Genomic studies of oocyte physiology reveal mechanisms critical to oocyte competence [PDF]
, 2011 In vitro maturation of porcine oocytes has been intensively studied for many years. However, the in vitro maturation system is still inefficient to produce competent oocytes that can develop to viable embryos.

Cell‐Based Biohybrid Micro/Nanorobots for Biotherapy
Advanced Robotics Research, EarlyView.This review systematically evaluates cell‐based biohybrid micro/nanorobots (CB‐BMRs), highlighting their cell selection criteria, fabrication strategies, and diverse actuation modes. Furthermore, it surveys the promising therapeutic applications of CB‐BMRs in targeted cancer, thrombosis, and inflammation treatments, while comprehensively discussing ...

Oocyte and embryo quality after coasting: the experience from oocyte donation [PDF]
Human Reproduction, 2002 Oocyte donation provides us with an opportunity to study the clinical outcome of oocytes, retrieved from women undergoing coasting, in recipients in whom endometrial receptivity is unaltered by the coasting procedure. Thus, our aim was to describe oocyte donation outcome in donors undergoing coasting, the oocyte and embryo quality obtained from these ...

MATERNAL DETERMINANTS OF OOCYTE AND EMBRYO QUALITY [PDF]
, 2011 Oocyte quality plays a critical role in establishment of pregnancies, embryo development, implantation and the health of offspring. The oocyte provides maternal factors necessary for the initial development of its embryo during the period of ...

Advanced Science, EarlyView.IGFBP4 is upregulated in granulosa cells of aged ovaries across monkeys, mice, and humans. It inhibits YAP signaling, thereby suppressing cell proliferation and contributing to follicular dysfunction. Deletion of Igfbp4 in granulosa cells enhances ovulatory output, improves hormone profiles, and reproductive performance in aged female mice, suggesting ...

Updating the markers for oocyte quality evaluation: intracellular temperature as a new index
Reproductive Medicine and Biology, 2018 Background The developmental competence of an embryo is principally dictated by the oocyte. Usually, oocyte selection is based on morphological properties; however, all morphological criteria that are currently used for the grading and screening of ...

BMC Biology, 2021 Background Although oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF) metabolites,
