Peroxisome proliferator-activated receptors (PPAR) play a critical physiological role in energy homeostasis, inflammation, and protective cardiovascular function. We assessed the antioxidant effect of clofibrate-induced receptor alpha (PPARα) stimulation on ischemic myocardium myocardial morphology hemodynamics. Male Wistar rats (300 g) were distributed into following groups: (1) Sham, (2) ischemia vehicle treated (MI-V), (3) clofibrate [100 mg/kg/ intraperitoneally) (MI-C). Reactive oxygen...

Under conditions of hyperglycemia and ischemia/reperfusion (I/R) injury, myocardial oxidative stress increases, leading to cellular damage. Inhibition has been reported be involved in the cardioprotective effects hydrogen sulfide (H2S) during I/R diabetes. Recent studies have shown that H2S potential protect heart. However, mechanism by which regulates level cardiac reactive oxygen species (ROS) hyperglycemic remains unclear. Therefore, objective this study was evaluate cytoprotective effect...

Renin-angiotensin system (RAS) activation promotes oxidative stress which increases the risk of cardiac dysfunction in metabolic syndrome (MetS) and favors local insulin resistance. Fibrates regulate RAS improving MetS, type-2 diabetes cardiovascular diseases. We studied effect fenofibrate treatment on myocardic signaling pathway Angiotensin II (Ang II)/Angiotensin type 1 receptor (AT1) its relationship with myocardial resistance MetS rats under heart ischemia. Control were assigned to...

Numerous studies have supported a role for oxidative stress in the development of ischemic damage and endothelial dysfunction. Crataegus oxyacantha (Co) Rosmarinus officinalis (Ro) extracts are polyphenolic-rich compounds that proven to be efficient treatment cardiovascular diseases.

Rosiglitazone (RGZ), a peroxisome proliferator-activated receptor gamma (PPARγ) ligand, has been reported to act as insulin sensitizer and exert cardiovascular actions. In this work, we hypothesized that RGZ exerts PPARγ-dependent regulation of blood pressure through modulation angiotensin-converting enzyme (ACE)-type 2 (ACE2)/angiotensin-(1-7)/angiotensin II type-2 (AT2R) axis in an experimental model high pressure. We carried on experiments normotensive (Sham) aortic coarctation...

Mexican women are increasingly migrating north, leaving their homes and families behind looking for private domestic work in U.S. cities. The journey, fraught with danger those lacking legal entry documents, involves moving across social cultural divides as well an international political border. Women bear this dislocation not through unencumbered choice, but within a context of structural constraint. contemporary movement borders is rooted globalization processes—the economic restructuring...

Metabolic syndrome (MetS) is a cluster of factors that increase the risk developing diabetes, stroke, and heart failure. The pathophysiology injury by ischemia/reperfusion (I/R) highly complex inflammatory condition plays an important role increasing matrix remodeling cardiac apoptosis. Natriuretic peptides (NPs) are hormones with numerous beneficial effects mainly mediated cell surface receptor named atrial natriuretic peptide (ANPr). Although NPs powerful clinical markers failure, their in...

Myocardial infarction (MI) has been associated with an inflammatory response and a rise in TNF-α, interleukin (IL)-1β, IL-6. Peroxisome proliferator-activated receptors (PPARs) promote decreased expression of molecules. We aimed to study whether PPAR stimulation by clofibrate decreases inflammation reduces infarct size rats MI. Male Wistar were randomized into 3 groups: control, MI + vehicle, (100 mg/kg). Treatment was administered for consecutive days, previous 2 h induced increase protein...

Myocardial infarction (MI) initiates an inflammatory response that promotes both beneficial and deleterious effects. The early helps the myocardium to remove damaged tissue; however, a prolonged later brings cardiac remodeling characterized by functional, metabolic, structural pathological changes. Current pharmacological treatments have failed reverse ischemic-induced damage. Therefore, our aim was study if clofibrate treatment capable of decreasing inflammation apoptosis, ventricular...
