Effects of monoamine precursors on food intake in male rats were studied. Rats were subjected to an artificial circadian pattern of eating, i.e., a five-hour feeding program during daytime and food deprived during the rest of day. Feeding responses after treatment of drugs were examined. Intraperitoneal injection of L-beta-3, 4-dihydroxyphenylalanine(More)
Somewhere between the portability of a smartphone and configurability of a laptop lies the Raspberry Pi with its capabilities as a powerful and portable Wi-Fi scanning device. This device runs contemporary wireless analysis tools and supports most industry used accessories including external Wi-Fi adaptors and GPS receivers. When compared to dedicated(More)

Effects of catecholamines and indoleamine precursors on the luteinizing hormone (LH) release induced by estradiol (E2) and progesterone (P4) in acutely ovariectomized (Ovx) rats were studied. Rats were Ovx on diestrus day 1 (D1) and received a spaced injection of E2 and P4 on D1 and D2, respectively. One of the following substances: L-beta-3,(More)
A decline in sexual arousal and copulatory activity has been observed in male rats with advancing age. Grafting of fetal hypothalamic tissue into the third ventricle of aged male rats restores sexual behavior. This study investigated the effects of grafting fetal preoptic area (POA) neurons into the POA of aged male rats exhibiting decreased sexual(More)
Treatment of neonatal female rats with androgen results not only in decreased female sexual behavior but also in enhanced male sexual behavior examined in adulthood. The effects of grafting fetal preoptic area (POA) neurons into the POA, and fetal hypothalamic (HPT) neurons into the ventromedial hypothalamus (VMH), were tested in neonatally(More)
The release of luteinizing hormone (LH) in young (3-4 months) and aged (24-25 months) ovariectomized female Sprague-Dawley rats, s.c. implanted with a 17 beta-estradiol benzoate silastic capsule, was studied in the presence and absence of stimulation by exposure to male rat urine. After taking an initial blood sample at 12:00 (reference sample), either(More)
This study examined the noradrenergic mechanism in regulation of luteinizing hormone (LH) release in short- and long-term ovariectomized (OVX) steroids-primed rats. All rats were OVX on the diestrous day 1(D1) morning about 1000 h. After OVX, rats in the short-term OVX group were immediately primed with estradiol (E2, 0.1 mg/kg BW s.c.), fitted with atrial(More)

The effectiveness of estradiol (E2) and progesterone (P4) in inducing the release of the luteinizing hormone (LH) in the acutely ovariectomized (OVx) rats was studied. Female rats were Ovx in different stages of the estrous cycles and received a series of injections of E2 and P4. LH dynamic changes in the blood were examined in the afternoon of the(More)
