The creation of human embryonic stem cells through the destruction of a human embryo pits the value of a potential therapeutic tool against that of an early human life. This contest of values has resulted in a polarized debate that neglects areas of common interest and perspective. We suggest that a common ground for pursuing research on human embryonic stem cells can be found by reconsidering ...

SARS-CoV-2 causes placental changes that can lead to embryonic/foetal death. However, the pregnant woman who in other diseases is considered (e.g., H1N1) a risk group for development of severe forms disease, COVID-19 rarely evolves with severity, except when childbirth occurs, and loses bond placenta.

introduction: dna damage, as an important initiator of neuronal cell death, has been implicated in numerous neurodegenerative conditions. previously we have delineated several pathways that control embryonic cortical neuronal cell death evoked by the dna-damaging agent, camptothecin. the camptothecin, topoisomerase ι inhibitor, has been shown to induce cortical neuronal cell death in a reproduc...

A key event in the development of the mammalian cerebral cortex is the generation of neuronal populations during embryonic life. Previous studies have revealed many details of cortical neuron development including cell birthdates, migration patterns and lineage relationships. Programmed cell death is a potentially important mechanism that could alter the numbers and types of developing cortical...

Abstract Background Cranial radiation therapy for treating childhood malignancies in the central nervous system or accidental exposure may result neurological side effects surviving adults. As tissue homeostasis is maintained by stem cells, understanding effect of on neural cells will provide clues managing effects. Drosophila embryos were used as a model whose sensitivity to irradiation-induce...

ARIAN embryonic mortality has long been a subject of biological interest. It is also a problem oœ obvious economic importance. The total embryonic mortality of domestic fowl, Gallus gallus, has been progressively increasing for some time. Less than 30 years ago, when flocks were small and kept at large, the embryonic death rate rarely exceeded i0 per cent. As simple and primitive methods of pou...

noncompaction of the ventricular myocardium is an embryonic cardiomyopathy that is increasingly being recognized. noncompaction of lv myocardium, right ventricular myocardium, or both can occur in isolation, in congenital heart diseases, in valvular heart diseases, in neuromuscular disorders, skeletal abnormalities and in endocrinologic abnormalities. clinical manifestations of ventricular non-...
