Yoga and other body-mind techniques enjoy an increasing popularity in many fields of health maintaining practices, in prevention of some illnesses and in curative medicine in spite of our incomplete knowledge about its applicability and effects. There are large differences among the various yoga-schools and the heterogeneity of indications etc.

Hahnemann considered the secondary action of medicines to be a law of nature and reviewed the conditions under which it occurs. It is closely related to the rebound effects observed with many modern drugs. I review the evidence of the rebound effect of statins that support the similitude principle. In view of their indications in primary and secondary prevention of cardiovascular diseases, statins are widely prescribed.
The use of complementary and alternative medicine (CAM) among menopausal women has increased in the last years. This review examines the evidence from systematic reviews, RCTs and epidemiological studies of CAM in the treatment of menopausal symptoms. Some evidence exists in favour of phytosterols and phytostanols for diminishing LDL and total cholesterol in postmenopausal women. Similarly, regular fiber intake is effective in reducing serum total cholesterol in hypercholesterolemic postmenopausal women.
Four groups of 25 rabbits each, were studied to determine the effect of Haritaki (Terminalia chebula), Amla (Emblica officinalis) and Bahira (Terminalia belerica) on cholesterol-induced hypercholesteolaemia and atherosclerosis. The control group was fed with cholesterol alone; the Haritaki group received Haritaki and cholesterol; the Bahira group received Bahira and cholesterol; and the Amla group received Amla and cholesterol for 16 weeks.

Hypercholesteremia is one of the risk factors for coronary artery disease. The present study highlights the efficacy of Ayurvedic herbal formulation Triphala (Terminalia chebula, Terminalia belerica, and Emblica officinalis) on total cholesterol, Low density lipoprotein (LDL), Very low density lipoprotein (VLDL), High density lipoprotein (HDL) and free fatty acid in experimentally induced hypercholesteremic rats.
Excessive production of reactive oxygen species (ROS) contributes to progression of atherosclerosis, at least in part by causing endothelial dysfunction and inflammatory activation. The class III histone deacetylase SIRT1 has been implicated in extension of lifespan. In the vasculature,SIRT1 gain-of-function using SIRT1 overexpression or activation has been shown to improve endothelial function in mice and rats via stimulation of endothelial nitric oxide (NO) synthase (eNOS). However, the effects of SIRT1 loss-of-function on the endothelium in atherosclerosis remain to be characterized.
As the elderly population is increasing rapidly, there is a lot of scientific interest in clarifying the differential life-style, genetic, biochemical and molecular factors contributing to mortality or exceptional longevity. Within the framework of the ZINCAGE project, 249 old (60-85 years) and nonagenarian Greek subjects (>/=85 years old) were recruited and anthropometrical, blood and biochemical indices as well as blood pressure measurements were obtained.
The scientific foundations for risk factor modification in the elderly are three-fold: (1) data from long-term prospective population studies demonstrating significant independent relationships between established major risk factors--particularly blood pressure (systolic and diastolic), serum cholesterol, cigarette use, clinical diabetes--and risk of cardiovascular (CV) morbidity and mortality; (2) data from population studies on time trends of mass changes in major risk factors and parallel changes in CV mortality rates, including large sustained declines; (3) data from randomized controll
Changes in lipid metabolism with age result in lower total serum cholesterol and low-density lipoprotein concentrations. There is no evidence that longevity and lipid profiles are influenced by genetic make-up. It is difficult to establish an optimum total serum cholesterol in the elderly but values established in younger subjects give a guide. High-density lipoprotein may be even more protective in the elderly and could turn out to be a better predictor of coronary disease. Screening for the treatment of hypercholesterolaemia should be carried out in the elderly.
Advances in treatment of elevated cholesterol levels and recent documentation of efficacy and safety in clinical trials justify expanded use of cholesterol-lowering therapy in clinical practice. Patients with CHD or other forms of clinical atherosclerotic disease can benefit from aggressive cholesterol management. Maximal dietary modification, weight control, and physical activity are valuable adjuncts to drug therapy in secondary prevention. Recent studies have shown that appropriate use of cholesterol-lowering drugs is cost-effective and efficacious in patients with CHD.
