Did a brick fall on your head? Urgently introduce polyethylene glycol!
A solution of polyethylene glycol can be used as an emergency aid for various brain injuries. Perhaps soon it will become a mandatory component of first aid kits.

01.07.2008In three years, the proceeds of a thriving funeral home from the evisceration of corpses amounted to almost five million dollars. Donor organs with fictitious permits of relatives of the deceased were sent to various medical centers in the USA and Canada.
01.07.2008Liquid crystals can undergo changes in their organization in response to a slight change in the primary structure of DNA, including mutations at the level of one nitrogenous base.
01.07.2008Atherosclerosis of the coronary arteries significantly increases the likelihood of myocardial infarction. When identifying people who are at risk for cardiovascular diseases, it is necessary to pay attention to the calcium index of the coronary artery.
30.06.2008There is a pronounced inverse relationship between coffee consumption and the risk of liver cancer. In addition, a high level of the liver enzyme gamma-glutamyltransferase in the blood is associated with an increased risk of developing the disease.
30.06.2008In elderly people, lack of sleep can aggravate already, as a rule, impaired protective reactions to abnormal folding of protein molecules, the frequency of which increases as the cell ages. The accumulation and aggregation of abnormal proteins in the cell is associated with many diseases, including Alzheimer's and Parkinson's diseases.
30.06.2008Type 2 diabetes is associated with chronic oxidative stress, which plays an important role in the processes of deterioration of cognitive function and the development of Alzheimer's disease. Eating fatty foods can lead to a sharp increase in the level of free radicals that trigger oxidative stress and damage tissues, including brain tissue.
30.06.2008In Europe, expensive medicines are most often forged. In Russia, medicines are forged according to the principle of popularity – those that are in great demand are chosen.
27.06.2008Taking as a basis the fact that white blood cells – leukocytes – perform the function of fighting infections and thus prolong human life, scientists at the University of Palermo analyzed the relationship between life expectancy and the content of leukocytes in the blood.
27.06.2008Several substances have been identified that inhibit the binding of regulatory regions of DNA with the estrogen-receptor complex activating them. These compounds effectively blocked the production of proteins that stimulate the growth and proliferation of cancer cells expressing
27.06.2008The authors believe that this discovery expands the therapeutic possibilities of introducing normal tRNAs into defective mitochondria of patients in order to correct violations.
27.06.2008The results of the study open the way to the development of new classes of drugs for the treatment of Alzheimer's disease. The high selectivity of the action of such drugs is assumed, since, unlike the ApoE gene, the CALHM1 gene is active only in the brain.
26.06.2008The authors believe that, in general, genomic health is an inherited factor, and epigenetic changes observed during life explain the increasing predisposition to the development of various diseases with age.
26.06.2008The level of dehydroepiandrosterone sulfate – a precursor that the body converts into female and male sex hormones – in the blood of men is a strong prognostic factor of longevity.
26.06.2008Existing miRNA tracking tags glow for no more than a minute, while quantum dots emit light for many hours. Moreover, the new approach is 5-10 times less toxic to living cells than the chemical compounds currently used to monitor the course of RNA interference.
26.06.2008The ability to control a computer without the help of hands excites the minds of neurophysiologists all over the world, and several interfaces have already been created that connect a computer with different organs of the human body and directly with the brain. Scientists from the Research Institute of Physiology named after A.A.Ukhtomsky St. Petersburg State University suggest using eye movement for this purpose. The first experiments confirmed that this method works.
25.06.2008Many generations of parents tell their children about the need to eat vegetables, because "vegetables are the key to health." Recently, these persuasions were supported by the results of a study that demonstrated the benefits of vegetables, especially if you use them all your life.
25.06.2008A preliminary study of the drug "Stemamin" showed that its composition does not correspond to the formulation stated in the regulatory documentation. According to the expert opinion, this remedy does not contain living cells, since stem cells cannot live in any cosmetic forms.
25.06.2008With the introduction of insoluble, as well as soluble one- and three-molecular forms of beta-amyloid, no recorded effects were observed. However, the introduction of a two-molecular soluble beta-amyloid caused the development of symptoms characteristic of Alzheimer's disease in rats.
24.06.2008Harvard researchers have deciphered the mechanisms underlying the fact that the ROCK1 protein significantly suppresses inflammation of the vascular walls in atherosclerosis, which is the main cause of heart attacks and strokes. The authors found that ROCK1 is necessary for immune cells – macrophages – to clean the walls of blood vessels from fat deposits. A normal side effect of such cleansing is inflammation, but often this process gets out of control, which causes the opposite result - the growth of atherosclerotic plaques and blockage of arteries.
