Journal ArticleDOI
Acute lead exposure increases arterial pressure: role of the renin-angiotensin system.
Maylla Ronacher Simões,Rogério Faustino Ribeiro Júnior,Marcos Vinícius A. Vescovi,Honério Coutinho de Jesus,Alessandra Simão Padilha,Ivanita Stefanon,Dalton Valentim Vassallo,Mercedes Salaices,Mirian Fioresi +8 more
TL;DR: Acute exposure to lead below the reference blood concentration increases systolic arterial pressure by increasing angiotensin II levels due to ACE activation, and offers further evidence that acute exposure tolead can trigger early mechanisms of hypertension development and might be an environmental risk factor for cardiovascular disease.
Journal ArticleDOI
Low-level lead exposure increases systolic arterial pressure and endothelium-derived vasodilator factors in rat aortas.
Jonaina Fiorim,Rogério Faustino Ribeiro Júnior,Edna Aparecida Silveira,Alessandra Simão Padilha,Marcos Vinícius A. Vescovi,Honério Coutinho de Jesus,Ivanita Stefanon,Mercedes Salaices,Dalton Valentim Vassallo +8 more
TL;DR: The results suggest that on initial stages of lead exposure, increased SBP is caused by the increase in plasma ACE activity, and this effect is accompanied by increased p-eNOS, iNOS protein expression and Na+/K+-ATPase functional activity.
Journal ArticleDOI
Low Mercury Concentration Produces Vasoconstriction, Decreases Nitric Oxide Bioavailability and Increases Oxidative Stress in Rat Conductance Artery
Núbia Belem Lemos,Jhuli Keli Angeli,Thaís de Oliveira Faria,Rogério Faustino Ribeiro Júnior,Dalton Valentim Vassallo,Alessandra Simão Padilha,Ivanita Stefanon +6 more
TL;DR: Investigating the acute effects of 6 nM HgCl2 on endothelial function of aortic rings suggests that acute low concentration mercury exposure, occurring time to time could induce vascular injury due to endothelial oxidative stress and contributing to increase peripheral resistance, being a high risk factor for public health.
Journal ArticleDOI
Myocardial contractility is preserved early but reduced late after ovariectomy in young female rats.
Altemar Santos Paigel,Rogério Faustino Ribeiro Júnior,Aurélia Araújo Fernandes,Gabriel Pelegrineti Targueta,Dalton Valentim Vassallo,Ivanita Stefanon +5 more
TL;DR: It is demonstrated that myocardial contractility and expression of key Ca2+ handling proteins were preserved in the early phase and reduced at long-term during OSHs deprivation.
Journal ArticleDOI
Exposure to low mercury concentration in vivo impairs myocardial contractile function.
Lorena Barros Furieri,Mirian Fioresi,Rogério Faustino Ribeiro Júnior,Maria Visitación Bartolomé,Aurélia Araújo Fernandes,Victoria Cachofeiro,Vicente Lahera,Mercedes Salaices,Ivanita Stefanon,Dalton Valentim Vassallo +9 more
TL;DR: In isolated hearts mercury treatment promoted contractility dysfunction as a result of the decreased NKA activity, reduction of NCX and SERCA and increased PLB protein expression, offering further evidence that mercury chronic exposure, even at small concentrations, is an environmental risk factor affecting heart function.
