Although acute exercise is apparently pro-inflammatory and increases oxidative stress, it can promote the necessary stress stimulus to train chronic adaptations in patients with chronic heart failure (CHF). This study aimed to compare the effects of exercise intensity and duration on the inflammatory markers soluble tumor necrosis factor receptor (sTNFR1) and interleukin-6 (IL-6), and on oxidative stress [malondialdehyde (MDA) and antioxidant enzymes: catalase (CAT) and superoxide dismutase (SOD)] in individuals with CHF...

Ischemic cardiomyopathy (IC) is the major cause of heart failure. Conventional medicine has been proved ineffective with adverse effects. Soybean presents exciting adjunctive therapies and shows protective benefits for IC. However, the molecular mechanisms remain unclear. Isoflavones are the main bioactive components of soybean and may be protective against heart disease. Isoflavones were extracted by using an acidic-ethanol method and analyzed by HPLC. All patients with ischemic stroke were randomly and evenly assigned to two groups: the isoflavone group (80 mg day(-1), n = 100) and control group (80 mg day(-1) placebo, n = 100), and the whole period of the experiment was 24 weeks...

Hypercholesterolaemia is well known to be associated with mitochondrial dysfunction, subsequently leading to multiple organ failure. Similar to other natural products, sericin is a candidate for adjunctive therapy in hyperlipidaemic conditions. However, the cholesterol-lowering mechanisms of sericin are multifactorial and controversial. Here, a high-cholesterol-fed rat model with or without sericin treatment was established using a dosage of 1,000mg/kg/day for 30 days. Blood lipid profiles, oxidative stress markers (superoxide dismutase, SOD; malondialdehyde, MDA; nuclear factor erythroid 2-related factor, Nrf-2), dysmorphic mitochondria in relation to fission (dynamin-related protein-1; Drp-1) and fusion (guanosine triphosphatase mutated in dominant optic atrophy; OPA-1) markers and biosynthetic markers (aquaporin, AQP-1; tubulin-4β, Tb4B) in the pancreas and adrenal gland were evaluated...

Cardiac fibrosis induced by sustained pressure overload contributes to heart failure. Oxidative stress serves an important role in cardiac remodeling and heart failure independent of etiological factors. The application of hydrogen as an antioxidant is a novel concept in disease treatment, however no studies as present have investigated the effects of hydrogen on cardiac fibrosis. In the present study, the effects of hydrogen on pressure overload‑induced cardiac fibrosis and heart failure were investigated in abdominal aortic‑constricted rats...

Emerging evidence has suggested that intermedin (IMD), a novel member of the calcitonin gene‑related peptide (CGRP) family, has a wide range of cardioprotective effects. The present study investigated the effects of long‑term administration of IMD on cardiac function and sympathetic neural remodeling in heart failure (HF) rats, and studied potential underlying mechanism. HF was induced in rats by myocardial infarction (MI). Male Sprague Dawley rats were randomly assigned to either saline or IMD (0.6 µg/kg/h) treatment groups for 4 weeks post‑MI...

We tested the hypothesis that indirect measures of oxidative stress (vitamin E, glutathione peroxidase, and malondialdehyde) differ in dogs in heart failure resulting from either myxomatous mitral valve disease or dilated cardiomyopathy. Dogs were classified according to the International Small Animal Cardiac Health Council (ISACHC) classification. Additionally, the effect of cardiac therapy on oxidative stress parameters and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in advanced stages of congestive heart failure was investigated...

Background Cardiac toxicity is one of the life-threatening complications of cancer therapy. Cyclophosphamide (CYP) is an alkylating agent with potent antineoplastic and immunosuppressive properties and possibly the most widely used antineoplastic agent. Chronic cardiotoxicity associated with CYP is characterized by progressive heart failure developing from weeks to years after therapy. Methods In this study, rats were administered with (60 mg/kg and 120 mg/kg) alone or in combination with single intraperitoneal (200 mg/kg) administration of CYP for 7 days...

Salusin-α and salusin-β are expressed in many tissues including the central nervous system, vessels and kidneys; they have been shown to decrease endoplasmic reticulum stress during heart ischemia/reperfusion (I/R) and to decrease apoptosis. We investigated the relation of salusin-α and salusin-β levels to acute ischemic renal failure. We also investigated whether these peptides are protective against renal I/R damage. Fifty-three rats were divided into six groups: control, I/R, I/R + salusin-α1, I/R + salusin-α10, I/R + salusin-β1 and I/R + salusin-β10...

PURPOSE: Endurance training improves oxidative stress and vascular endothelial dysfunction in patients with chronic heart failure (CHF). However, patients with CHF and an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) often avoid endurance training for fear of ICD shock. Recent studies have reported that stretching exercises enhance antioxidant activity and improve vascular responses. Therefore, we aimed to assess the effects of 4 weeks of stretching exercises on oxidative stress and vascular endothelial function in patients with CHF with an ICD or CRT-D...

Sleep disruption after myocardial infarction (MI) by affecting ubiquitin-proteasome system (UPS) is thought to contribute to myocardial remodeling and progressive worsening of cardiac function. The aim of current study was to test the hypothesis about the increased risk of developing heart failure due to experience of sleep restriction (SR) after MI. Male Wistar rats (n = 40) were randomly assigned to four experimental groups: (1) Sham, (2) MI, (3) MI and SR (MI + SR) (4) Sham and SR (Sham + SR). MI was induced by permanent ligation of left anterior descending coronary artery...

Acetaminophen (APAP) overdose is a common cause of acute liver failure, and beta-blockers are commonly used drugs in clinical practice. This study aimed to evaluate the effect of two different beta-blocker agents as nebivolol and atenolol against APAP-induced hepatotoxicity. Male Wistar rats were treated with APAP (2 g/kg/day, p.o.) to induce hepatotoxicity. Our results showed that nebivolol and atenolol reduced heart rate and blood pressure. Nebivolol (5 mg/kg/day, p.o.) for 14 days has a hepatoprotective effect shown by significant decrease in hepatic injury parameters (serum AST and ALT) with significant suppression of hepatic malondialdehyde (MDA) and nitric oxide (NO) which were elevated with APAP administration...
