1. Flavonoids relaxed the contractions induced by noradrenaline, KCl or phorbol 12-myristate, 13-acetate in rat aortic strips, the order of potency being: flavonols (quercetin, kaempferol, pentamethylquercetin) > flavones(luteolin, apigenin) > flavanols((+)-catechin, (-)-epicatechin) which correlates with the reported order of potency to inhibit protein… (More)
1. Oral administration of quercitrin to rats for 3 days increases the mucosal glutathione contents in ileum and colon as well as inhibits non-enzymatic lipid peroxidation induced in membrane fractions from jejunal and colonic mucosa. 2. After 7 days of treatment with quercitrin, rat intestinal oxidative status trends to normalize to control rats.
1. Flavonoids produced a concentration-dependent relaxation of the contractile responses induced by noradrenaline, KCl, or phorbol 12-myristate-13-acetate in rat aortic rings. Only the flavonoid with three contiguous hydroxyls in B rings (myricetin), at low concentrations, potentiates the contractions evoked by these agonists. 2. The relaxant effects of… (More)
OBJECTIVES To estimate the prevalence of amnestic mild cognitive impairment (aMCI), cognitive impairment, no dementia (CIND) and dementia in a general elderly population and to examine the associated socio-demographic factors.

The Spanish Rare Diseases Registries Research Network (SpainRDR) is a project aimed to build the National Rare Diseases Registry in Spain based on the input of two different methods: patient outcome research registries and population-based registries. The project has been approved within the IRDiRC framework and is co-funded by the Institute of Health… (More)
BACKGROUND It is still unknown whether a correlation exists between left ventricular Tei index obtained by tissue Doppler imaging and that determined by flow Doppler waveforms. This study was conducted to evaluate their relationship and to assess the positional effect on them. METHODS Twenty-six healthy subjects and 25 patients with essential hypertension… (More)
