Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

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.

Embryo metabolism : what does it really mean? [PDF]
, 2015 The study of early embryo metabolism has fascinated researchers in the field for nearly a century. Herein, we give a brief account of the general features of embryo metabolism and some consideration of the research performed to reach such conclusions. It

Wildlife Biology, EarlyView.Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.ABSTRACT Background Caesarean scar ectopic pregnancy (CSEP) is defined by the implantation and development of a gestational sac inside a caesarean scar defect, but variations in classification systems and diagnostic criteria exist. Objectives This study aimed to systematically review the different criteria used in the medical literature to diagnose ...

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability
Andrology, EarlyView.ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Successful reprogramming of epiblast stem cells by blocking nuclear localization of β-catenin. [PDF]
, 2014 Epiblast stem cells (EpiSCs) in mice and rats are primed pluripotent stem cells (PSCs). They barely contribute to chimeric embryos when injected into blastocysts.

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.

Bta-miR-10b secreted by bovine embryos negatively impacts preimplantation embryo quality [PDF]
, 2019 In a previous study, we found miR-10b to be more abundant in a conditioned culture medium of degenerate embryos compared to that of blastocysts. Here, we show that miR-10b mimics added to the culture medium can be taken up by embryos. This uptake results
