Lado-Abeal J, Robert-McComb J, Qian X, Leproult R, Van Cauter E, Norman R
J Neuroendocrinol . 2005 Jun; 17(7):435-44. PMID: 15946161
When energy intake is restricted in mammals, there are neuroendocrine adjustments in the secretion of reproductive and metabolic hormones to reallocate energy for vital functions. In the present study, we...

WINICK C, Rothacker D, Norman R
Occup Med (Lond) . 2002 Mar; 52(1):25-30. PMID: 11872791
The objective was to evaluate the efficacy of worksite weight reduction programs at high-stress worksites. We employed a longitudinal study based on two meal replacements daily with subjects choosing a...

Lado-Abeal J, Clapper J, Norman R
J Neuroendocrinol . 2001 Jul; 13(7):650-5. PMID: 11442779
The first objective of this study was to investigate whether the inhibitory effect of insulin-induced hypoglycemia (IIH) on luteinizing hormone (LH) secretion was the same in unrestrained adult male rhesus...

McGlone J, Anderson D, Norman R
Contemp Top Lab Anim Sci . 2001 May; 40(3):21-5. PMID: 11353520
Studies were initiated to determine the effects of restricted (32.2 cm2 per mouse), normal (96.8 cm2), or excess floor space (129.0 cm2) allowances by using a model of three mice...

Huang B, Leu S, Yang H, Norman R
J Androl . 2001 May; 22(3):507-13. PMID: 11330652
Studies in the mouse have demonstrated for the first time in vivo regulation of gonadotropin-releasing hormone (GnRH) on the minute-to-minute dynamics of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release...

Lado-Abeal J, Hickox J, Cheung T, Veldhuis J, Hardy D, Norman R
Neuroendocrinology . 2000 Mar; 71(3):196-208. PMID: 10729791
Fasting inhibits the gonadotropic axis and stimulates the corticotropic and somatotropic axes. Since leptin is a product of fat cells that has been implicated in the control of both reproduction...

Lado-Abeal J, Mrotek J, Stocco D, Norman R
Eur J Endocrinol . 1999 Nov; 141(5):534-8. PMID: 10576772
Objective: Because glucocorticoids stimulate leptin release and, at least in vitro, leptin inhibits cortisol secretion, a feedback system between glucocorticoids and leptin has been proposed. However, in humans and non-human...

Lado-Abeal J, Lukyanenko Y, Swamy S, Hermida R, HUTSON J, Norman R
Clin Endocrinol (Oxf) . 1999 Sep; 51(1):41-51. PMID: 10468964
Objectives: Although the adipocyte protein leptin has been implicated in the control of reproductive function in rodents, its role in primate reproductive physiology is poorly understood. Because primates in puberty...

Lado-Abeal J, Norman R
Neuroendocrinology . 1998 May; 67(4):236-43. PMID: 9588693
During puberty, primates begin to secrete LH, and presumably GnRH, at night and then eventually throughout the day as they mature. We examined the role of vasopressin, a putative inhibitor...

Eeles R, Durocher F, Edwards S, TEARE D, Badzioch M, Hamoudi R, et al.
Am J Hum Genet . 1998 Apr; 62(3):653-8. PMID: 9497242
Prostate cancer shows evidence of familial aggregation, particularly at young ages at diagnosis, but the inherited basis of familial prostate cancer is poorly understood. Smith et al. recently found evidence...
