We investigated the modulation by growth factors of phospholipase C (PLC)-linked glutamate receptors during in vitro development of hippocampal cultures. In defined medium, glial cells represent between 3 and 14% of total cell number. When we added b

Long-term effects of subcutaneous melatonin implants on intrahypothalamic LHRH content and on pulsatile luteinizing hormone release have been investigated in ganglionectomized male mink. Animals were submitted to bilateral removal of the superior cer

This study explores changes in pituitary pulsatile Luteinizing Hormone (LH) secretion in intact and castrated male mink, either previously photogonadostimulated by short day treatment (LD 4:20), or maintained in a state of sexual quiescence by long d

The pulsatile secretion of the hypophyseal luteinizing hormone (LH) is induced by the pulsatile secretion of the hypothalamic neurons secreting gonadotrophin-releasing hormone (GnRH). Seasonal variations in the pulsatility of LH were studied in the a

This study was conducted to determine changes in thyroid-gonadal interaction in the edible dormouse during the phase of the annual cycle that corresponds to the end of the breeding season (from June to September). We evaluated intra-hypothalamic lute

We investigated the extent to which photoperiodic fluctuations synchronize annual thyroid and gonadal rhythmicity in edible dormice. The effects of different daylength manipulations (LD 4:20, LD 6:18, LD 18:6, LD 20:4) were examined during the two cr

The aim of this study was to elucidate the pituitary adjustments implicated in photoperiodic control of reproduction in two mammalian species, the ferret and the mink. In the ferret, which displays renewed testicular activity when the days lengthen,

1. The annual profiles of plasma thyroid-stimulating hormone (TSH), thyroxine (T4), luteinizing hormone (LH) and testosterone (T) concentrations in control and ganglionectomized (SCGx) dormice were analyzed to determine whether the pineal gland affec

The annual variations of the plasma testosterone concentrations (PT), and the metabolic clearance rate (MCR) of 3 H-testosterone, that permits evaluation of the secretion rate (SR = PT × MCR) of the hormone, have been measured in Pekin ducks reared

Changes in plasma LH, testosterone, and estrogens were investigated throughout reproduction and molt in free-living male and female emperor (Aptenodytes forsteri) and adelie (Pygoscelis adeliae) penguins. In both sexes and species, plasma LH and gona
