Increased homocysteine levels associated with sex and stress in the learned helplessness model of depression
(Elsevier B.V., 2004-01-01)
Elevated levels of homocysteine (Hey) have been associated with major depressive (MD) illness. As human females show a higher predisposition towards depression, this study examined how Hey levels in rats are affected by ...
Vascular smooth muscle reactivity to norepinephrine in ovariectomized rats: Relationship to vascular PGE2/PGF2α ratio
(1995)
1. 1. We have recently demonstrated that, in normal female rats, vascular reactivity (VR) and vascular prostaglandin-E2 (PGE2) and prostacyclin production are influenced by the ovarian cycle. 2. 2. In this study, we ...
Monitoring ovarian cycles, pregnancy and post-partum in captive marsh deer (Blastocerus dichotomus) by measuring fecal steroids
(Oxford Univ Press, 2018-01-25)
The marsh deer is an endangered species from the marshlands of central South America. This study aimed to characterize certain aspects of the reproductive physiology of marsh deer hinds, including the duration and fecal ...
Ultrasound evaluation of ovarian follicular dynamics in Jennies (Equus asinus) during the estrous cycle
(Univ Federal Rural Pernambuco, 2009-07-01)
The ovarian activity was accessed by ultrasound throughout 10 estrous cycles from Jennies (Marchador Brasileira). Daily ultrasound examinations were performed and the dada was retrospectively studied based on daily ...
Effect of urea in the diet on ovarian follicular dynamics and plasma progesterone concentration in Alpine goats
(Revista Brasileira de Zootecnia, 2017)
Effects of thyroid status on NEI concentration in specific brain areas related to reproduction during the estrous cycle.
(Elsevier Science Inc, 2013-09)
Abstract: We previously showed that short-term hypo- and hyperthyroidism induce changes in neuropeptide glutamic-acid-isoleucine amide (NEI) concentrations in discrete brain areas in male rats. To investigate the possible ...
The role of the estrous cycle in activity-based anorexia: A comparative study of sexual differences in rats
(2013)
The present study evaluates the effects of the estrous cycle on activity-based anorexia by identifying the successive phases of the estrous cycle of female rats before, during, and after exposure to the experimental ...
