Abstract: The evaluation of embryo viability is typically based on morphologic and morphometric grading systems, which are known to be heavily affected by differences in subjective judgement. A significant proportion of euploid embryos do not implant… read more here.

DOI: 10.1016/j.jinsphys.2021.104327
Abstract: The chorion covering/protecting insect egg, which has some effective functions such as providing mechanical strength, protecting eggs from external environments, and keeping moisture adjustment, is one of the principal barriers to manipulation, cryopreservation, and study… read more here.
