Hyperhomocysteinemia (HHcy)-abnormally elevated plasma levels of homocysteine (Hcy)-has been associated with the development of neurodegenerative dementia and mild cognitive impairment. This association suggests that HHcy might facilitate memory loss in the elderly. As memory loss can occur through a deteriorated neurogenic capacity, we have studied the(More)
The hippocampus is a brain area characterized by its high plasticity, observed at all levels of organization: molecular, synaptic, and cellular, the latter referring to the capacity of neural precursors within the hippocampus to give rise to new neurons throughout life. Recent findings suggest that promoter methylation is a plastic process subjected to(More)
The location of hypothalamic paraventricular neurons projecting to sympathetic preganglionic levels and related to the autonomic regulation of various organs involved in glucose metabolism (OGM) was determined by ipsilateral injections of two fluorescent tracers, Diamidino Yellow into the left dorsal motor nucleus of the vagus and Fast Blue into the left(More)
Insulin and glucose play a key role in the control of body energy homeostasis. However, the anatomical organization of the network of central insulin and glucose sensitive areas is still unclear. In the present study, we used a multiple-labelling technique combining retrograde tracing and Fos-like immunohistochemistry, to analyse the anatomical projections(More)
Anorexia inducing lithium chloride is believed to involve descending projections from hypothalamus to preganglionic autonomic output neurons. A multiple-labelling technique has presently been used to analyze the anatomical projections of lithium chloride sensitive neurons in the hypothalamus. Immunolabelling of c-fos was performed to stain neurons activated(More)

Abstract Background: Neuropsychiatric and neurological disorders frequently(More)
BACKGROUND Neuropsychiatric and neurological disorders frequently occur after brain insults associated with neuronal loss. Strategies aimed to facilitate neuronal renewal by promoting neurogenesis constitute a promising therapeutic option to treat neuronal death-associated disorders. In the adult brain, generation of new neurons occurs physiologically(More)
The present study analyzed the functional activity of granular and agranular insular cortices in contextual specificity of latent inhibition using a conditioned taste aversion paradigm. c-Fos immunolabeling was examined in insular cortex in preexposed and no preexposed groups under similar and different context conditions. Result showed that the exposition(More)
BACKGROUND The demographic structure has a significant influence on the use of healthcare services, as does the size of the population denominators. Very few studies have been published on methods for estimating the real population such as tourist resorts. The lack of information about these problems means there is a corresponding lack of information about(More)
