Therefore, these two breeds are good models for study of differential muscle and fat development. Prenatal body weight in fetus contributes to variations in postnatal growth performance in farm animals [11]. Previous studies have investigated whether developmental transitions are associated with large ...

An activated allele of the c-erbB-2 oncogene impairs kidney and lung function and causes early death of transgenic mice. The pathogenicity of the human c-erbB-2 oncogene was evaluated in transgenic mice. A DNA sequence comprising the promoter-enhancer region of the MMTV LTR a... St?cklin...
Imprinting – MAGEL2 – Porcine fetus – Association analysis – Imprinting varianceImprinted genes play an essential role in the regulation of fetal growth, development and function of the placenta, however only a limited number of imprinted genes have been studied in swine. In ...
the pseudoglandular stage and the canalicular stage show significant fluctuations in the plane values of the pulmonary parenchyma, the presence in different individuals of variants of the plane values of entodermal derivatives, which indicated individual morphotypes of the development of the rat lung. ...
Keywords: ethanol; FASD; developmental biology; fetus; oxidative stress 1. Introduction The toxic effects of alcohol, particularly on embryonic development, pose significant public health challenges. It is the main environmental cause of mental retardation and is a preventable cause [1]. Alcohol is ...
Despite the improvements in biotechnological approaches and the selection of controlled ovarian hyperstimulation protocols, the resulting pregnancy rate from in vitro fertilization (IVF) protocols still does not exceed 30–40%. In this connection, there is an acute question of the development of a non...
Surfactant production in the fetal lung does not begin until the last stages ofgestation, when the fetus prepares for air breathing; this transition may act as an important labour switch. The stages oflabour First stage:dilatation Early in labour, uterine contractions, orlabour pains, occur at ...
