Nutritional programming affects hypothalamic organization and early response to leptin.

abstract：:PTH increases calcium reabsorption exclusively in the distal nephron. Two mechanisms of Ca++ transport through the basolateral membrane (BLM) have been described: the ATP-dependent and the sodium gradient-dependent transport. In the present study, we investigated the effect of PTH and (Bu)2cAMP on these two mechanisms...
