Morphometric analysis of gametes and embryos is crucial for optimizing Intracytoplasmic Sperm Injection outcomes [PDF]

Cellular, Molecular and Biomedical Reports
Morphometric analysis of gametes and embryos is crucial for optimizing Intracytoplasmic Sperm Injection (ICSI) outcomes. This study aimed to evaluate the importance of morphometric parameters at oocyte, zygote, and embryo stages, focusing on their ...

Time-lapse technology for embryo culture and selection

Upsala Journal of Medical Sciences, 2020
Culturing of human embryos in optimal conditions is crucial for a successful in vitro fertilisation (IVF) programme. In addition, the capacity to assess and rank embryos correctly for quality will allow for transfer of the potentially ‘best’ embryo first,

#153 : Sperm Motility: Effect on Fertilization Rate and Embryo Quality in Patients Undergo Intracytoplasmic Sperm Injection in Indonesia

Fertility & Reproduction, 2023
Background and Aims: Progressive motility may be an indicator of adequate metabolic activity of the sperm; it is important in ICSI as it helps embryologists in picking a viable and best spermatozoa for injection.

Embryo Aggregation in Pig Improves Cloning Efficiency and Embryo Quality

PLOS ONE, 2016
Dans cette étude, nous avons analysé les effets de l'agrégation d'embryons clonés sur le développement embryonnaire in vitro et la qualité de l'embryon en mesurant le diamètre et le nombre de cellules du blastocyste, les niveaux de fragmentation de l'ADN et l'expression des gènes associés à la pluripotence, à l'apoptose, au trophoblaste et à la ...

Effect of Melatonin Supplementation on In Vitro Developmental Competence of Bovine Oocyte: A Systematic Review and Meta-Analysis

Veterinary Medicine International
Melatonin application in in vitro embryo production (IVEP) constitutes a promising research focus. Nevertheless, there remains a lack of comprehensive meta-analytical evidence assessing its effects in the bovine species. The present systematic review and

DHEA Supplementation Confers No Additional Benefit to that of Growth Hormone on Pregnancy and Live Birth Rates in IVF Patients Categorized as Poor Prognosis

Frontiers in Endocrinology, 2018
BackgroundIn vitro fertilization (IVF) patients receive various adjuvant therapies to enhance success rates, but the true benefit is actively debated. Growth hormone (GH) and dehydroepiandrosterone (DHEA) supplementation were assessed in women undergoing

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
