Dehydroepiandrosterone sulfate (DHEAS) is neuroprotective when administered either before or after injury in a focal cortical cold lesion model [PDF]

open access: yes, 2006
Dehydroepiandrosterone and its sulfate (DHEAS) are sex hormone precursors that exert marked neurotrophic and/or neuroprotective activity in the central nervous system.

Effect of Estradiol and Nonylphenol on mRNA Levels of VitellogeninII in the Liver of Chicken Embryos

open access: yesThe Journal of Poultry Science, 2001
Nonylphenol is one of the endocrine disrupting agents with estrogenic activity in some vertebrates. The present study was conducted to assess estrogenic activity of p-nonylphenol (NP) in chicken embryos by determining mRNA levels of liver vitellogenin II

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

open access: yes, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...
