The paraventricular nucleus (PVH) of the hypothalamus is a key region for the control of food intake. It presents a very high neuropeptide Y (NPY)-like positive innervation. In this paper we have studied the modifications of NPY-positive innervation in the PVH of 72 h starved rats vs control rats by means of semiquantitative immunocytochemistry. We observed(More)
Hox genes specify the structures that form along the anteroposterior (AP) axis of bilateria. Within the genome, they often form clusters where, remarkably enough, their position within the clusters reflects the relative positions of the structures they specify along the AP axis. This correspondence between genomic organization and gene expression pattern(More)
UCP2 is expressed in pancreatic β cells where its postulated uncoupling activity will modulate glucose-induced changes in ATP/ADP ratio and insulin secretion. The consequences of UCP2 over/underexpression on β-cell function has mainly been studied in the basal state; however, a UCP has no uncoupling activity unless stimulated by fatty acids and/or reactive(More)
Functional laryngectomies permit a more or less ideal preservation of laryngeal functions whose recovery, especially in les conservative operations, occurs very slowly and depends on several conditions: post operative course, sensitivity and motility of the hypopharynx, patient's ability to restore swallowing mechanisms. The Authors relate their experience(More)
The increase in metabolic efficiency during energy restriction seems to be an established phenomenon in obese patients. The sympathoadrenal system is involved in the control of energy expenditure and the catecholamine responses to stimuli vary during the day. We therefore studied the circadian pattern of urinary catecholamine excretion during 4-h(More)
