(Texas A&M University, 2007-09-17)Manganese (Mn) is considered important for normal growth and reproduction. Because Mn can cross the blood brain barrier and accumulate in the hypothalamus, and because it has been suggested that infants and children are ...

Characterization of puberty and growth near puberty in five cattle breeds and their diallel crosses (Texas A&M University. Libraries, 1977)Pubertal measurements and monthly weight and height measurements of 424 bulls and 475 heifers involved in a diallel mating of Angus, Brahman, Hereford, Holstein and Jersey cattle were analyzed to characterize puberty and ...

(Texas A&M University, 2005-11-01)Angus-sired heifers were allotted by age (mean=4 mo), BW (mean=135 kg), and sire (n=4) to either a control (n=10) or infected group (n=11; 600 metacercariae of Fasciola hepatica, intraruminally) to test our hypothesis that ...

(2011-10-21)Developmental changes within the hypothalamus are necessary for maturation of the reproductive neuroendocrine axis. Recent reports have implicated several neuronal networks in this process, but genes involved in their ...

(2012-02-14)Increased pulsatile release of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) is critical for pubertal initiation of ovarian cycles in female mammals. Kisspeptin, a peptide product of the Kiss1 gene, ...

(2014-05-01)Accelerated body weight gain during the juvenile period leads to early maturation of the reproductive neuroendocrine system and puberty by advancing the onset of high-frequency release of gonadotropin-releasing hormone ...
-
(2014-06-26)Nutritional and metabolic statuses during postnatal development control the timing of pubertal maturation in mammals. Studies reported herein had two overall aims. In Aim I, objectives were to characterize functional and ...
-
(2013-07-22)This dissertation presents three separate studies exploring parents’ perceptions and recommendations for communicating with their third, fourth, and fifth grade children about human sexuality. First, a systematic literature ...
-
(2018-02-08)Links between nutrition and reproductive success in heifers are well established; however, achieving a high plane of nutrition is costly, and reproductive success remains uncertain, making heifer development both expensive ...

(2014-08-28)The pubertal initiation of a high-frequency, pulsatile release of gonadotropin-releasing hormone (GnRH) involves an escape from estradiol negative feedback. Kisspeptin neurons are proposed to mediate the effects of estradiol, ...
