- Antioxidant markers and cardiovascular risk factors in Azorean subjects with coronary artery diseasePublication . Ferin, Rita; Gomes, Carla; Castro, Ana Rita; Martins, Dinis; Santos, Víctor; Santos, Maria Cristina; Lopes, Paula Alexandra; Baptista, José; Viegas-Crespo, Ana Maria; Pavão, Maria LeonorTo evaluate some blood antioxidant parameters in azorean subjects with coronary artery disease (CAD) previously submitted to percutaneous revascularization (PCI), by considering some cardiovascular risk factors.
- Biotechnological conversion of Azorean bovine cheese whey for the production of bio-energyPublication . Rego, E.; Paiva, Lisete S.; Lima, Elisabete; Baptista, JoséThe world's economies, in most countries, are heavily dependent on fossil fuels. This reliance is becoming increasingly problematic taking into account that reserves are rapidly depleting, and no less important is the strong effect of fossil fuel emissions on the global carbon cycle.

- Plasma aminothiol status in the population of the Island of São Jorge (The Azores Archipelago, Portugal)Publication . Ferin, Rita; Correia, Cristina; Raposo, Mafalda; Gonçalves, Bruno; Gonçalves, C.; Baptista, José; Pavão, Maria LeonorHcy, Cys, Cys-Gly and GSH are low molecular weight thiols that play important roles in the metabolism and homeostasis of the organism. An altered plasma aminothiols status can cause oxidative stress, thus contributing to atherogenesis. The aim of this study was to evaluate the plasma levels of total Hcy, Cys, Cys-Gly and GSH, as well as GGT activity in apparently healthy subjects from the Island of S˜ao Jorge, taking into consideration gender and lipid profile. The study group was formed by 73 subjects with no chronic diseases, aged 20 to 60 years, born living in the island of S˜ao Jorge. The evaluation of the four aminothiols was carried out by HPLC with an isocratic reversephase column using a fluorescence detector. Mean values of GSH (1.8±0.6mM) and Cys (240±35mM) content were under reference values, but Cys-Gly was above. Plasma total Hcy, Cys and Cys-Gly levels, as well as GGT activity were significantly higher in men than in women (respectively, 30%, 7%, 17% and 65%). About 63% of subjects were hyperlipidemic, mainly hypercholesterolemic. Cys concentration was increased by 9% in hyperlipidemics vs. normolipidemics. In subjects with altered thiol status men, but not women, revealed a moderate hyperhomocysteinemia. Also Cys-Gly concentrations were significantly higher in men than in women. In spite of being apparently healthy, all subjects (namely men) have depleted antioxidant defenses, indicating high oxidative stress. Alterations in plasma GSH, Cys-Gly and Cys concentrations, taken together, and independently of dyslipidemia, could be considered as early markers of atherosclerosis.
- Prevalence of Heart Disease Risk Factors in the AzoresPublication . Ferin, Rita; Schaefer, Ernst J.; Horvath, Katalin; Baptista, José; Pavão, Maria LeonorBACKGROUND and AIMS: In the Azores age adjusted death rates from coronary heart disease (CHD) are two-fold higher than in mainland Portugal. We determined the prevalence of standard and emerging CHD risk factors in 206 female and 146 male Azorean subjects (mean age 41 years).
