The hypothalamic neuropeptide melanin-concentrating hormone (MCH) increases feeding when injected intracerebroventricularly in rats. To identify the hypothalamic nuclei responsible for the orexigenic effect, we injected the peptide into discrete hypothalamic nuclei known to express the MCH receptor, MCH1R. MCH (0.6 nmol) elicited a rapid and significant(More)
Absorbing phase transitions (APT) are a category of critical nonequilibrium phase transitions, widespread in condensed matter physics and population and epidemics modeling [1]. Directed percolation (DP) [1] has been recognized as the paradigmatic example of a system exhibiting a transition from an active to a unique absorbing phase. DP defines a precise(More)
A deranged mucosal immune response and dietary factors may play an important role in the pathogenesis of type 1 diabetes. The aims of our work were to look for the presence of small intestinal enteropathy in non-obese diabetic (NOD) mice in relation to the presence of wheat proteins in the diet, and to assess their role in the risk of developing diabetes.(More)
The role of diet in the prevention of diabetes remains uncertain. The aim of this study was to investigate two different dietary aspects, i.e. adherence to the Mediterranean diet and glycaemic load (GL), in relation to diabetes occurrence. We analysed data from the Greek cohort of the population-based European Prospective Investigation into Cancer and(More)
Endogenous NO inhibits insulin release in isolated beta cells and insulin-degrading enzyme activity in hepatocytes, while NO release from endothelial cells has been suggested to enhance insulin action. We assessed the overall effect of systemic inhibition of endogenous NO synthesis on glucose homeostasis in humans. Twenty-four non-diabetic volunteers(More)
The central nervous system modulates cardiovascular function and fluid and electrolyte balance in part through the actions of vasoactive peptides/neurotransmitters. The presence of several vasoactive peptides and their receptors in the hypothalamus suggests a possible interaction at this site. One level at which vasoactive peptides such as arginine(More)
Immune effects of four Fusarium-toxins (FB1, ZEA, NIV, DON) on the proliferation of Jurkat cells and porcine lymphocytes: in vitro study L. Severino & R. Russo & D. Luongo & R. De Luna & R. Ciarcia & M. Rossi Published online: 6 August 2008 # Springer Science + Business Media B.V. 2008
Intracerebroventricular (ICV) injection of Agouti related protein (AgRP), an endogenous melanocortin 3 and 4 receptor (MC3/4-R) antagonist, produces a prolonged increase in food intake. To clarify the roles of the MC3-R and MC4-R in AgRP-induced hyperphagia, the feeding effect of AgRP (83-132) was compared with that of the selective MC4-R antagonist,(More)
Objectives. To describe 2 cases of thyrotoxic periodic paralysis. Methods. We report of 2 cases of thyrotoxic periodic paralysis in 2 individuals from 2 different backgrounds with emphasis on their presentation and treatment. We also conducted a literature search to put together an update review of thyrotoxic periodic paralysis. Results. A 47-year-old(More)
