PURPOSE Exercise training is a nonpharmacological intervention that improves cardiovascular function and enhances endothelial homeostasis in patients with cardiovascular diseases. However, the amount of benefit achieved varies widely depending on the type and duration of exercise. Moreover, data about the long-term effects of physical activity are scarce.(More)
Two series of N-[5-oxo-4-(arylsulfonyl)-4,5-dihydro-1,3,4-thiadiazol-2-yl]-amides were synthesized and tested in vivo for their analgesic and anti-inflammatory activities. All the new compounds possess good antalgic action in the acetic acid writhing test and some terms of the series showed also fair anti-inflammatory activity in the carrageenan rat paw(More)
The synthesis and the pharmacological activity of a series of 1-aroyl derivatives of kynurenic acid methyl ester (4-oxo-quinolin-2-carboxy methyl (KYNA) esters), structurally related to NSAID indomethacin are described. The derivatives were screened in vivo for anti-inflammatory and analgesic activities. Most of the compounds exhibited good(More)
The synthesis in excellent yields of 2,3-dihydro-6-mercapto-1,3,5-triphenyl-2-thioxo-4(3H)-pyrimidinone 3 and 5-ethoxycarbonyl-2,3-dihydro-6-mercapto-1,3-diphenyl-2-thioxo-4(3H )- pyrimidinone 4 by reaction of methyl phenylacetate or diethyl malonate, respectively, with phenyl isothiocyanate (3 molar equivalents) and sodium hydride (2 molar equivalents) in(More)
A series of angelicin heteroanalogues, in which the furan was replaced by thiophene or a 1-substituted pyrazole moiety, was synthesised in order to obtain potential therapeutic agents with antiproliferative and/or other biological activities. In general, the antiproliferative activity of the new thioangelicin, tested in different biological substrates,(More)
Gastroesophageal acid reflux (GER) is a common disorder associated with the exacerbation of asthma. In this study we investigated the effects on the airways of intraoesophageal HCl instillation in the rabbit and the role of tachykinins in these effects. In anaesthetized New Zealand rabbits bronchopulmonary functions [total lung resistance (R(L)) and dynamic(More)
The therapeutic usefulness of doxorubicin, an antineoplastic drug, is limited by its cardiotoxicity whose mechanism is as yet unknown. Several hypotheses have been postulated including also the release of vasoactive substances, so the aim of the present investigations was to study the relationship between the release of vasoactive substances and the(More)
In conscious rats with normal arterial blood pressure or with spontaneous or DOC induced hypertension, effects of drugs increasing (cycloserine, ethanolamine-o-sulphate, piracetam, chlordesmethyldiazepam) or depressing (bicuculline, Ro 15-1788, PK 11195) GABAergic reactivity were evaluated on the arterial hypotension and sinus bradycardia induced by(More)
The aim of this study was to test the effects of age and chronic exercise training on antioxidant and heat shock protein (Hsp) expression by comparing the hearts of young (Y), sedentary old (SO) and trained old (TO) rats. In SO rats, there were: (a) changes in myocardial structure and function; (b) increased malondialdehyde levels; (c) no changes in(More)
