The aim of this study was to compare the effects of a physical exercise test and of voluntary hyperventilation between controls and children with absence epilepsy. Eighteen children (6 controls and 12 epileptics) were studied during rest (R), a maximal physical exercise test (15 min; PE), recovery (REC) and voluntary hyperventilation (3 min; VHPV). EEG and(More)
We report our experience concerning clinical and paraclinical features of multiple sclerosis in 19 children. The disease was highly variable in its presentation but acute episodes of retrobulbar optic neuritis or transverse myelitis or cerebellitis were commonly observed at the onset. Diagnosis was very often suspected as soon as the first episode when(More)
This experiment was undertaken to determine whether the estrogen-induced LH and GnRH surge in the ewe is associated with activation of a specific subpopulation of neurons in the mid-brain of the ewe as indicated by a change in GnRH mRNA levels. Fifteen ovariectomized ewes were assigned to treatment groups 3-4 wk after ovariectomy. One group of ewes served(More)
Gonadotropin-releasing hormone (GnRH) receptor expression is regulated by estradiol and GnRH itself. The objective of this experiment was to determine the extent to which low levels of estradiol, similar to those observed during the transition from the luteal to the follicular phase of the estrous cycle, and GnRH interact to regulate expression of GnRH(More)
Expression of GnRH receptors increases prior to the onset of the preovulatory surge of LH in sheep. Two experiments were conducted to investigate the interactions of progesterone (P) and estradiol (E) on amounts of mRNA for GnRH receptors and the number of receptors for GnRH. The first study was designed as a 2 x 2 factorial arrangement of treatments to(More)
