Grading of Mammalian Cumulus Oocyte Complexes using Machine Learning for in Vitro Embryo Culture [PDF]

arXiv, 2016
Visual observation of Cumulus Oocyte Complexes provides only limited information about its functional competence, whereas the molecular evaluations methods are cumbersome or costly. Image analysis of mammalian oocytes can provide attractive alternative to address this challenge.

Non‐Invasive Prenatal Testing by Cell‐Free DNA (cfNIPT) for Detecting Turner Syndrome With Mosaicism and Structural Variants—Prenatal Findings and Postnatal Outcomes

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.

Activation of ADF/cofilin by phosphorylation-regulated Slingshot phosphatase is required for the meiotic spindle assembly in Xenopus laevis oocytes [PDF]

, 2013
We identify Xenopus ADF/cofilin (XAC) and its activator, Slingshot phosphatase (XSSH), as key regulators of actin dynamics essential for spindle microtubule assembly during Xenopus oocyte maturation.

Spider Eye Development Editing and Silk Fiber Engineering Using CRISPR‐Cas

Angewandte Chemie International Edition, EarlyView.
Spiders exhibit unique traits with significant implications for a diversity of fields, and gene editing provides new opportunities for advancing research in these areas. In this study, we developed a CRISPR‐Cas9 protocol for spiders, enabling gene knock‐outs/knock‐ins to study gene function and introduce new phenotypic traits. Abstract CRISPR‐Cas9 gene

Mitochondria directly influence fertilisation outcome in the pig [PDF]

, 2006
The mitochondrion is explicitly involved in cytoplasmic regulation and is the cell's major generator of ATP. Our aim was to determine whether mitochondria alone could influence fertilisation outcome.

SET Improved Oocyte Maturation by PP2A and Inhibited Oocyte Apoptosis in Mouse Oocytes

, 2021
Abstract Background: SET is a multifunctional protein involved in a variety of molecular processes such as transcription control, chromatin remodeling, cell apoptosis, and cell-cycle regulation. In ovaries SET is predominantly expressed in theca cells and oocytes. And in PCOS patients the expression of SET was increased than normal people.

Quality control in oocytes by p63 is based on a spring-loaded activation mechanism on the molecular and cellular level

eLife, 2016
Mammalian oocytes are arrested in the dictyate stage of meiotic prophase I for long periods of time, during which the high concentration of the p53 family member TAp63α sensitizes them to DNA damage-induced apoptosis.

Why so many sperm cells? [PDF]

arXiv, 2014
A key limiting step in fertility is the search for the oocyte by spermatozoa. Initially, there are tens of millions of sperm cells, but a single one will make it to the oocyte. This may be one of the most severe selection processes designed by evolution, whose role is yet to be understood. Why is it that such a huge redundancy is required and what does

In Vitro Fertilization (IVF) Cumulative Pregnancy Rate Prediction from Basic Patient Characteristics [PDF]

arXiv, 2019
Tens of millions of women suffer from infertility worldwide each year. In vitro fertilization (IVF) is the best choice for many such patients. However, IVF is expensive, time-consuming, and both physically and emotionally demanding. The first question that a patient usually asks before the IVF is how likely she will conceive, given her basic medical ...
