Abstract Purpose To investigate whether heat shock protein 90 (HSP90) is involved in complement regulation in ischemic postconditioning (IPC). Methods The left coronary artery of rats underwent 30 min of occlusion, followed by 120 min of reperfusion and treatment with IPC via 3 cycles of 30s reperfus...
SUMMARY INTRODUCTION In acute myocardial infarction (AMI), each 18 mg/dl (1 mmol/L) increment is associated with a 3% increase in mortality rates. All strategies applied for reducing blood glucose to this date, however, have not presented encouraging results. METHODOLOGY We searched the Medline (PubMed...
Considering the recognized role of thyroid hormones on the cardiovascular system during health and disease, we hypothesized that type 2 deiodinase (D2) activity, the main activation pathway of thyroxine (T4)-to-triiodothyronine (T3), could be an important site to modulate thyroid hormone status, which wo...
Ghrelin is a novel growth hormone-releasing peptide administered to treat myocardial infarction (MI). However, the underlying mechanism of its protective effects against MI remains unclear. A total of sixty healthy Sprague Dawley male rats were included. The first one is the sham-operated control group w...
Lactate modulates the expression of lactate oxidation complex (LOC)-related genes and cardiac blood flow under physiological conditions, but its modulatory role remains to be elucidated regarding pathological cardiac stress. The present study evaluated the effect of lactate on LOC-related genes expressio...
Abstract Background: Remote ischemic preconditioning (RIPC) represents an attractive therapy for myocardial protection, particularly when ischemic events can be anticipated. Although several hypothetic mechanisms have been proposed, no definite molecular pathways have been elucidated. Objective: We eva...
Investigaciones sobre el ATP han revelado principios fundamentales de biología molecular cuyos descubridores fueron galardonados con el premio Nobel de química en 1997. En este artículo se revisan avances recientes sobre síntesis e hidrólisis del ATP y su relación con el metabolismo cardiaco. La s...
Existen múltiples evidencias que establecen la importancia de las lipoproteínas como factores de riesgo en la génesis de la ateroesclerosis. Los estudios epidemiológicos realizados en paises desarrollados han revelado que aproximadamente un tercio de los sobrevivientes de infarto miocárdico menores ...
