Na+/K+ ATPase α1 and β3 subunits are localized to the basolateral membrane of trophectoderm cells in human blastocysts.
Human reproduction (Oxford, England) ·doi:10.1093/humrep/deac124

Study questionIs there a relation between specific Na+/K+ ATPase isoform expression and localization in human blastocysts and the developmental behavior of the embryo?Summary answerNa+/K+ ATPase α1, β1 and β3 are the main isoforms expressed…

A novel approach for evaluating antibodies against SARS-CoV-2 using menstrual blood collected from sanitary napkins before and after vaccination and evaluation of the visual napkin score
·doi:10.21203/rs.3.rs-737828/v2

Abstract BackgroundAlthough saliva, whole blood, serum, plasma, urine, and feces have been used as specimens for SARS-CoV-2 antigen and antibody tests, menstrual blood has not been reported to date. Unlike invasive blood collection methods…

Effects of localisation of uterine adenomyosis on outcome of in vitro fertilisation/intracytoplasmic sperm injection fresh and frozen-thawed embryo transfer cycles: a multicentre retrospective cohort study
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-021-00764-7

BACKGROUND: Uterine adenomyosis is a benign disease, common among women in their 40 and 50 s, characterised by ectopic endometrial tissue in the uterine myometrial layer. Adenomyosis causes infertility and has a negative effect on the outco…

Human frozen-thawed blastocyst morphokinetics observed using time-lapse cinematography reflects the number of trophectoderm cells.
PloS one ·doi:10.1371/journal.pone.0210992

Recent studies reported morphokinetic indices for optimal selection of embryos in assisted reproductive technology (ART). The morphokinetics in blastocyst stage include the collapse and re-expansion rates after thawing. However, evaluation …
