Acta Obstetricia et Gynecologica Scandinavica, EarlyView.Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...

Effect of equilibration time on clinical and neonatal outcomes in human blastocysts vitrification
Reproductive Medicine and Biology, 2020 Purpose Prolonged exposure to equilibration solutions may be detrimental to an embryo's developmental potential, whereas a shorter exposure may affect the penetration of cryoprotectants into blastomeres.

Bioessays, 2015 The mammalian blastocyst exhibits a high capacity for aerobic glycolysis, a metabolic characteristic of tumours. It has been considered that aerobic glycolysis is a means to ensure a high carbon flux to fulfil biosynthetic demands.

Challenges and possible clinical applications of human embryonic stem cell research [PDF]
, 2012 Human embryonic stem cells (hESC) are harvested from the inner cell mass of the pre-implantation embryo and possess several unique characteristics. First, they are self-renewing, meaning they can grow indefinitely in an appropriate culture environment ...

Liminal Bioethics for Liminal Statuses: A New Method for Analysing Novel Biological Entities
Bioethics, EarlyView.ABSTRACT Novel biological entities such as cell lines and organoids do not typically fit into established conceptual categories, such as ‘human’ or ‘nonhuman’, ‘gift’ or ‘property’. This makes developing robust ethical principles or policy solutions difficult.

New biosensors and transgenic mice for multiplex cGMP imaging
British Journal of Pharmacology, EarlyView.Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP
