The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

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 ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Lifestyle Management in Menopause: A Systematic Review of Women With Premature Ovarian Insufficiency

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Premature ovarian insufficiency (POI), the loss of ovarian function before age 40, increases the risk of cardiovascular disease, low bone mineral density, dementia and psychological distress. Lifestyle interventions reduce chronic disease risk in other populations and, with hormone therapy, may improve health outcomes in POI.
