Ghrelin induces orexigenic behavior by activation of growth hormone secretagogue 1 receptors (GHSRs) in the ventral tegmental area (VTA) as well as hypothalamus, suggesting the involvement of mesolimbic dopamine system in the action of ghrelin. The present study aimed to identify neuronal mechanisms by which peripherally administered ghrelin regulates the(More)

Height, which is partially determined by GH secretion, is genetically influenced. The purpose of this study was to identify polymorphisms in the GH-1 gene, which are associated with altered GH production. The subjects included prepubertal short children with GH insufficiency without gross pituitary abnormalities (n = 43), short children with normal GH(More)
Both high gain and transconductance at low operating voltages are essential for practical applications of organic field-effect transistors (OFETs). Here, we describe the significance of the double-layer capacitance effect in polar rubbery dielectrics, even when present in a very low ion concentration and conductivity. We observed that this effect can(More)
