Although most work on prenatal stress has been conducted on mammalian species, birds provide useful alternative models since avian embryos develop outside the mother's body in a concealed… (More)
The relationship between maternal stress during pregnancy in humans and the subsequent physical and mental health disorders in their children has inspired a wide array of studies on animal models.… (More)
Glucocorticoids affect reproductive hormone production in many species. In chickens, elevated plasma corticosterone down-regulates testosterone and progesterone concentrations in plasma, but also in… (More)
Paraplegias of traumatic origin may be classified as primary or secondary. Secondary traumatic paraplegia (STP) is believed to result from an autodestructive process. Different authors have published… (More)
Effects of maternal hormones may adaptively adjust offspring development to prevailing conditions. However, Darwinian fitness of parents is maximized by investing in more than one offspring while… (More)
Despite considerable research on hormone-mediated maternal effects in birds, the underlying physiology remains poorly understood. This study investigated a potential regulation mechanism for… (More)
In this paper, we study the distribution functions that arise naturally during selfsimilar radial infall of collisionless matter. Such matter may be thought of either as stars or as dark matter… (More)
Wind variability in OB stars may be ubiquitous, and a connection between projected stellar rotation velocity and wind activity is well established. However, the origin of this connection is unknown.… (More)
A new model for the high-energy emission from pulsars is developed by considering charged particle motion in the fields of a spinning, highly magnetised and conducting sphere in vacuum. A generally… (More)
