This week on health news:
A new study suggests that older women who drink from two to three cups of coffee a day may reduce the possibility of dementia and other forms of cognitive impairment. Scientists have long been suggested that caffeine is a mild stimulant, which is present in coffee, tea, and other products, that increases the cognitive benefits.
According to the research, caffeine can improve long-term memory, as well as stimulate delaying the cognitive decline later in life. The results are based on analysis of the consumption of coffee in 6.467 women aged 65 years and older. The researchers took into account correlation between caffeine consumption and the incidence of dementia in the elderly. Professor of psychiatry at the University of Wisconsin-Milwaukee Ira Driscoll along with a team examined reported volunteers, for the amount of caffeine consumed in various forms. As can be seen from the analysis, women who consumed more than 261 mg of caffeine a day (2-3 cups of coffee or about 6 cups of tea), demonstrated a 36% reduction in the risk of diagnosis of cognitive impairment and dementia. Potential, the protective effect of caffeine is associated with the fact that it blocks adenosine A2A receptors that influence aging and age-related pathologies.
Nicotine is a very addictive habit that makes the renunciation of the causes stress, weight gain or irritability hence the abandonment of smoking becomes severe. Recently, however, came a breakthrough in the treatment of nicotine dependence in the form of protein receptors located in the brain, which may help in the fight against addiction.
Smoking is the leading cause of deaths worldwide, and existing drugs, such as nicotine patches, chewing gum or other methods, are not the entirely good solution to fight the addiction. Scientists are trying to discover what effect on the brain has nicotine, causing such a strong habit. A breakthrough in the research, it may be a molecular understanding of the impact of nicotine on our body, and more specifically the Α4β2 receptors, which binds nicotine opening the way to the ions of cells. The new strategy is to help find a way to a large number of nicotinic receptors by infecting them with the human virus cell line, which will require to coding the particular types of proteins. A detailed study on the development of treatments for addiction will probably last a long time, but it may also be an important discovery in the treatment of epilepsy, mental illnesses, and dementia.
If the rainy autumn weather makes you lose motivation for training, perhaps the most recent findings, will encourage activity again. As can be seen from the results of researchers from the University of Florida, during the exercises, our body releases the hormone that not only helps us to drop extra weight but above all prevents its accumulation.
Regular workouts cause the hormone isolated from the muscle cells, may influence the treatment of diabetes, cancer, and obesity. Previous studies have shown further that this hormone can help to transform white fat to brown adipose tissue (the so-called good fat), that allows us to burn more calories. Studies carried out on 28 samples of fat cells taken from individuals who have undergone the procedure reducing the breast, and they have shown that the brown fat, rises to five times the growth of cells containing the UCP1 protein which is essential for fat burning. Released during the workout hormone can reduce the growth of fat cells from 20-60%, which without a doubt should encourage physical activity every day. There is no need to wait for a wonder drug, it is worth however to start to move, and beneficial hormones will help reduce fat, strengthen bones, improve the cardiovascular system, and overall health.
New studies indicate that docosahexaenoic acid – omega-3 found in fish, seafood, or food supplements may avoid the emergence of lupus.
The researchers suggest that omega-3 fatty acid DHA can prevent lupus caused by exposure to crystalline silica – a toxic mineral, associated with the development of systemic lupus erythematosus. Lupus is an autoimmune disease in which the immune system mistakenly attacks and destroys healthy tissue, cells, and organs, causing pain and inflammation. According to the research carried out on in mice, Omega-3 may even by 96%, reduce the risk of lung lesions in individuals exposed to silica. This reaction is unusual because so far rarely been observed that comprehensive protection in the lungs.
