BACKGROUND: Influenza is a highly infectious viral disease that is particularly common in the winter months. Oscillococcinum(®) is a patented homeopathic medicine that is made from a 1% solution of wild duck heart and liver extract, which is then serially diluted 200 times with water and alcohol. OBJECTIVES: To determine whether homeopathic Oscillococcinum(®) is more effective than placebo in the prevention and/or treatment of influenza and influenza-like illness in adults or children.
The objective of this study was to assess evidence for the efficacy and effectiveness of Chinese qigong exercise in rehabilitative programs among cardiac patients. Thirteen databases were searched through to November 2010, and all controlled clinical trials on Chinese qigong exercise among patients with chronic heart diseases were included. For each included study, data was extracted and validity was assessed. Study quality was evaluated and summarized using both the Jadad Scale and the criteria for levels of evidence.

Chronic insomnia affects a significant proportion of the general population worldwide, and is associated with several serious medical conditions. From the Western scientific literature, hyper-arousal (on the cognitive-emotional, behavioral, autonomic, or central nervous system level) is a final common pathway involved in its pathogenesis.
Cardioprotective effect of ethanolic extract of Terminalia chebula fruits (500 mg/kg body wt) was examined in isoproterenol (200 mg/kg body wt) induced myocardial damage in rats. In isoproterenol administered rats, the level of lipid peroxides increased significantly in the serum and heart. A significant decrease was observed in the activity of the myocardial marker enzymes with a concomitant increase in their activity in serum. Histopathological examination was carried out to confirm the myocardial necrosis. T.
Antioxidant activity of ethanolic extract of fruits of Terminalia chebula (500 mg/kg body wt, orally for 30 days) against isoproterenol-induced oxidative stress was investigated in rats. The levels of serum lipid peroxides, iron, ascorbic acid, vitamin E, plasma iron-binding capacity, and the activities of ceruloplasmin and glutathione were assayed, in addition to the activities of the antioxidant enzymes--glutathione peroxidase, glutathione reductase, glutathione-S-transferase, superoxide dismutase and catalase in the heart tissue.
A comparison of the data published in anatomy textbooks and anthropological tables does not reveal any change in basic heart dimensions during the period since the beginning of the 20th century to nowadays. However, normal values of many other parameters have changed up to 30% over the same period. These changes may be caused by the acceleration phenomenon or the extension of average lifespan.
Born in Arles on February 21st 1875, Madame J. C. was the oldest registered human being. She died on August 4th 1997 at the age of 122 years, the record for longevity probably for a long moment. Based on this unique case and a review of the literature, the authors describe the mechanical, physiological and clinical aspects of normal cardiac ageing. The diseases of the elderly which accelerate the process of physiological ageing are then reviewed.
Cardiac fibrosis is critically involved in the adverse remodeling accompanying dilated cardiomyopathies (DCMs), which leads to cardiac dysfunction and heart failure (HF). Connective tissue growth factor (CTGF), a profibrotic cytokine, plays a key role in this deleterious process. Some beneficial effects of IGF1 on cardiomyopathy have been described, but its potential role in improving DCM is less well characterized.

The protective effect of heme oxygenase-1 (HO-1) expression in cardiovascular disease has been previously demonstrated using transgenic animal models in which HO-1 is constitutively overexpressed in the heart. However, the temporal requirements for protection by HO-1 induction relative to injury have not been investigated, but are essential to employ HO-1 as a therapeutic strategy in human cardiovascular disease states.
The prevalence of heart diseases, such as coronary artery disease and congestive heart failure, increases with age. Optimal therapeutic interventions that antagonize aging may reduce the occurrence and mortality of adult heart diseases. We discuss here how molecular mechanisms mediating life span extension affect aging of the heart and its resistance to pathological insults. In particular, we review our recent findings obtained from transgenic mice with cardiac-specific overexpression of Sirt1, which demonstrated delayed aging and protection against oxidative stress in the heart.
