The heart reacts to the musical vibrations

U.S. doctors have found that music is a reaction of the human cardiovascular system. Listen to your favorite quiet music and a positive impact on the health of the heart, said researchers from America. According to a new study experts found that the endothelium (the layer of cells lining the inner surface of vessels) reacts to the emotions.

It endothelium plays an important role in the regulation of blood flow, blood coagulability and the density of its status largely on the risk of developing cardiovascular disease. During the experiment, test subjects had to listen to different music, from the cheerful and calm to loud and disturbing.

It turned out that blood vessels grown in 4 times more of the listeners happy and calm music that positively influences the health of the cardiovascular system, as compared with those who listen to loud music and disturbing. Experts advise to listen to quiet music, and thereby enhance their health.

Strict diet leads to the formation of blood clots

Meals on grapefruit can lead to amputation of lower limbs. Women who adhere to strict grapefruit diet, developed American scientists. Washington doctors claim that a diet based on grapefruit, combined with birth control pills caused a severe impact from the 42-year-old woman.

UK expert stressed that this was an unusual case, but in his view, the strict diet can lead to unpredictable consequences. In November 2008, a woman brought to the emergency department. The day before, she went into a long car trip, after which I felt severe pain in the left leg ankle. When she was taken to the hospital, she had difficulty walking, shortness of breath and dizziness.

Shortly before the incident, the patient sat on a strict diet, which included 225 grams of grapefruit every morning, and previously the woman consumed very little fruit. After the ultrasound, doctors found a large blood clot that can lead to gangrene and loss of limbs. The woman had the necessary assistance and to prevent severe consequences. Specialists believe that strict grapefruit diet has provoked the emergence of a blood clot in leg vein women.

Relax on the sea is dangerous to health

Russian scientists warn: If you are going to resort to carefully examine how the composition of medicines and cosmetics, which use. If you were among the first antibiotics, sulfanilamidnye, diuretic and protivodiabeticheskie, hypnotics and sedative drugs (eg, containing extract of hunters), boric and salicylic acids, painkillers tablets containing ibuprofen, while the second was eosin, retinoic acid, essential oils bergamot, roses, musk, sandalwood and orange, you get the risk of allergic reaction in the sun.

The thing is that these substances cause increased skin sensitivity to ultraviolet - photosensitization, because of what it may appear red and itchy blisters, similar to the scientists. Therefore, when choosing their study medication instructions - if they indicated that the drug has side effects - or if the photo in cosmetics is one of the components, make another choice.

Employed people are less prone to stress

Researchers from Germany found that the unemployed are sick, on average, twice as long as working people. According to a recent study, the unemployed in Germany are sick longer than those who have jobs. The findings were based on data from health insurance TKK 2008. According to experts, is likely to cause stress and psychological stress associated with unemployment.

According to the TKK, in 2008 the length of a hospital in unemployment averaged 20.6 days, while workers - from 10.3 days (males) to 12.6 days (female). Of citizens of the work, the duration of all sick auxiliary workers (18.9 days).

Followed by the builders working wood-processing industry (18.5 days), metallurgy (17.6 days) and warehouse workers (17.0 days). Least extended sick gardeners (8.4 days), and administrative employees (9 days), the researchers reported. Frequent illness unemployed are not accidental. Unemployment, according to the authors of the study involves a severe mental stress, which have a negative impact on physical health.

Bleeding gums

German scientists found that the use of two grapefruit a day reduces the inflammatory diseases of the mouth. Doctors from the Friedrich Schiller University invited 58 smokers and nonsmokers people with chronic gum disease. Two weeks later it was found that in both groups increased the level of vitamin C and decreased bleeding gums.

And smokers have it though and doubled compared to the initial reading, but still was lower than that of nonsmokers. It is known that the level of vitamin C in smokers by an average of 29 per cent lower than that of nonsmokers.

The study confirmed that the prevention of inflammatory diseases of the gums is an adequate content of vitamin C. Because it is impossible to stock, it is better to regularly use products that are rich in this valuable vitamin. The content of vitamin C in grapefruit is 92.5 mg, which is why it is so useful.

Sweeteners affect liver

U.S. scientists discovered the role of fructose as one of the links in the chain of biochemical reactions leading to the increment in weight. Fructose (fruit sugar) found in fruits and honey. It turns out it is fructose, may cause our body to feel hungry when we do not need food. This discovery may explain the obesity epidemic that is raging in many developed countries.

First sweetener increases the level of cholesterol in the blood, then is obesity with metabolic syndrome, and, finally, leads to type two diabetes. Fructose increases the level of uric acid in the blood that blocks the effects of insulin - the primary hormone regulating glucose utilization and accumulation.

Even in rats, known to be resistant to the action of harmful factors, diet enriched with fructose, during the ten weeks, resulting in higher content of uric acid in the blood and the formation insulinorezistentnosti.

Exercise trains the brain

Doctors from the University of Oregon Health and Science found that regular exercise enhances mental development. The work was carried out in primates, 24 monkeys were used. The scientists explained their choice of topics that they wanted to eliminate the influence of factors such as smoking, alcohol and obesity. The animals were divided into three groups.

The first group trained at the track, five days a week for 20 weeks. The second group were not subjected to physical stress. The third group trained for 20 weeks, and then restrict their mobility. Then the researchers evaluated the volume of capillaries in the brain of animals from all three groups.

Head of research group, also said Judy Cameron, physical exercise may lead to a greater ability to concentrate and it's another important reason to make people pay more attention to sports.

The components of marijuana can be used to treat cancer

The active component in marijuana, can reduce the growth of cancer, say Spanish specialists. Scientists conducted an experiment in which the effect on mice with tumors of the components of marijuana. It turned out that these components can not only slow down the development of tumors, but also to destroy cancer cells. The study was published in the Journal of Clinical Investigation. Researchers believe that it is necessary to continue to investigate the properties of components in marijuana, and on the basis of it, may create new drugs and treatment methods that will with fewer side effects to reduce the intensity of the growth of cancerous tumors. Cannabis - substances derived from the variety of hemp, which contains a large number of psychoactive substances . However, according to research British medical journal Lancet, marijuana, took 11th place on the harmfulness of the list of harmful drugs (alcohol and tobacco took 5th and 9th places, respectively).

Cod-liver oil is able to defeat cancer

Omega-3 fatty acids that help fight cancer, reduced tumors in mice and make the chemotherapy more effective, said the Egyptian scientists. Scientists conducted a study which found that there is a huge benefit from the consumption of such products, such as salmon. These products are rich in omega-3 fatty acids that help fight cancer and prevent their occurrence, say experts. The study was published in Cell Division journal. Researchers studied the effects of omega-3 fatty acids in mice with tumors. It turned out that the fatty acid effect on solid tumors, which grew from rodents, and impeding their development, as well as omega-3 fatty acids are very well worked with cisplatinium - drug chemotherapy. Scientists believe that, based on the research, you can create a new, more effective method of treatment for solid cancers. Also, once again proved the benefits of fish consumption, which contains a lot of useful properties and may even help fight and prevent severe disease.

Among people over 45 doubled incidents of sexual infections

Many people in middle age continue to recklessly about their sexual health, said experts. Scientists conducted a study, which was attended by 2,000 adults. It turned out that one-fifth of the respondents aged 45 to 54 years were in the past five years, having unprotected sex with non-partners. Over the past decade, doubled cases sexually transmitted infections among people over 45 years. Among young people the prevalence of genital infections was lower, the researchers reported. According to researchers, such negligence resulted in part the fact that the age of 45 years is rarely possible to get pregnant, and people older generation do include sexually transmitted diseases, to the younger generation, but no infections age difference, experts stressed. The researchers recommend not to forget about using condoms to people of all ages.

Drinking energy drink with have heart failure is dangerous

American doctors from Henry Ford Hospital call abandon energy drinks, patients with hypertension and cardiovascular disease. Scientists conducted a study, which was attended by volunteers, to drink two cans of energy daily. Cardiac rhythm and pressure of the experiment participants were measured for 30 minutes after consumption of the drink, then after an hour, two, three and four hours.

The frequency of cardiac rhythm for the first day of testing was increased by 7.8%, and a week later - at 11%. Blood pressure at the end of the study improved at least by seven per cent. Doctors warn that patients with a heart and the effects of unstable pressure receiving energy drinks may be serious, and seriously harm health. According to them, have the power potential risk for heart and hypertension and the core such drinks is strictly contraindicated, even in small doses.

The content of high levels of caffeine and taurine in energy may be responsible for increasing pressure and rapid pulse, feel clinicians. It is shown that both substances have a direct impact on cardiac function. The level of caffeine in a bank of energy drink is the amount corresponding to at least one or two cup of coffee.

Relaksin reduces the risk of death from the cores

Hormone of pregnancy has a relaxing effect on muscles of blood vessels. Relaksin also reduces the cases of sudden cardiac arrest and enhances survival during cardiac arrest, proved the American researchers. Scientists have found that hormone relaksin, develops during pregnancy, is safe and can be reduced. People who have high blood pressure, doctors prescribe vasorelaxant funds, which gradually leads to a weakening of the heart and oxygen starvation of internal organs.

Specialists conducted a study, which was attended by 234 elderly people, survivors of cardiac arrest. Some patients received the drug with the hormone, and gave the rest a placebo. After 48 hours, researchers found that those who received the drug with the hormone, reduced dyspnea by 17% compared with those who took placebo.

According to the researchers, the hormone is safe and can increase survival in people at risk of cardiac arrest. Only in the United States stop the heart moved 5.3 million people. The disease is chronic and the State allocated huge funds for its prevention and treatment.

Drug addicts quickly lose their memory

Even if ecstasy is used in a short time, it does not save the brain from damage. A new study by scientists from Amsterdam showed that the use of ecstasy weakening function memorization. The study was conducted on animals and found that ecstasy permanently damage neurons involved in the development of serotonin, a chemical associated with mood, working memory and other brain activity.

Ecstasy also has a strong influence on the hippocampus - a brain area associated with the transition of short-term memory in the long term. Recently, a team of scientists led by Ben Shmandom of Amsterdam University attracted to the study of 188 volunteers who had previously never tried ecstasy, but were going to do it in the near future. Scientists have conducted psychological testing of volunteers, includes memory and attention.

A few months later the volunteers called for new tests and found that 58 of them at least once over time tried ecstasy. Despite the low dosage, the researchers diagnosed they have a small but statistically significant decrease of the ability to memorize. The test was to remember 15 words, and playing them in 20 minutes. Scientists report that the study confirms the neurotoxicity of the drug ecstasy, which, inter alia, leads to a lower level of serotonin in the brain.

Americans are protected from papillomavirus

The study examined the relationship between the detection of human infections and various factors. Such as: the presence of foreskin, race, sexual behavior, age. As a result of the work it was found that men who received the procedure for removal of foreskin, HPV is found on average 70 percent less.

The study included 998 men from the United States, Mexico and Brazil at the age of 18 to 70 years, each of which was discovered at least one form of HPV, and a control group of 403 healthy men. Human papillomavirus results to changes in the growth of tissues, causing the appearance of warts, and is transmitted through sexual intercourse.

Young people aged 18 to 24 years, the virus is detected in one and a half times more likely than men older than 45. Scientists have noted that similar data were obtained from studies carried out previously in Spain, Denmark, Ecuador, Thailand and the Philippines. In addition, a study in Spain showed that women whose partners were circumcised, the risk of cervical cancer, on average, lower by 42 per cent.

Receiving medication monitor sensor in tooth

The group of scientists from Israel, with the support of the EU completes its work on the project a miniature device for dosed introduction of drugs, which may be indigenous prosthesis implant in the patient's tooth - IntelliDrug project. According to the author of innovative ideas, an Israeli dentist Dr. Andy Wolff, a new way of introducing drugs has several clear advantages. The point is that patients are usually not inclined to comply with the prescribed regime of medication, even if it affects their lives. Furthermore, the additional inconvenience to patients frequently results in the need to take medication at night. Full automation of the process of introducing drugs into the body could once and for all solve the problems. In particular, implanted in a tooth doser medication can greatly facilitate the lives of diabetes patients, forced to do a few injections of insulin a day. Designed by scientists of the instrument called IntelliDrug includes medication reservoir, a pump, control valve, the microprocessor and battery. The medicine will be injected to the inside of your cheeks, where it will be quickly absorbed in the mucous membrane, and without delay, enter the blood. Currently, a prototype device successfully tested on pigs, is slightly higher than the size of a human tooth, but in the next few months, the developers intend to reduce it to acceptable parameters. Clinical trials IntelliDrug is scheduled to begin later this year.

Protects against HIV proteins are obtained from the leaves of tobacco

American and British scientists have proposed a cheap way to get large amounts of protein capable of neutralizing the human immunodeficiency virus. In the experiment with genetically modified plants, the scientists managed to obtain 60 grams of protein. That number was enough to produce 1 million doses of the gel microbicides to protect against HIV infection.

Microbicides gel to protect against HIV may be an important additional means of HIV prevention in developing countries. The development of such tools is especially important to protect the health of women who do not always have the opportunity to insist on safe sex.

However, all held at the date the test gels to protect against HIV infection does not lead to desired results. According to researchers, new and more promising active ingredients for such products may become protein, produced by red algae. Earlier laboratory experiments showed that able to communicate with the immunodeficiency virus and prevent its penetration into the cell.

To lower the costs of extraction of the substance, researchers in the Kentucky tobacco plants infected tobacco mosaic virus, which was built in the gene encoding griffitsin. Modified in this way the plants were able to produce the desired protein in sufficient quantities for commercial production.

With a modified tobacco planted area managed area 460 square meters to get about 60 grams griffitsina. That number was enough to produce 1 million doses of microbicides gel. However, in order to prove not only cheap but also the effectiveness of the gel, the scientists have yet to be a number of preclinical and clinical studies, evaluation of the results of which could a few years.

People with multiple sclerosis lower risk of cancer

People diagnosed with multiple sclerosis lower risk of cancer. Perhaps this is due to changes in lifestyle after the patient was diagnosed with neurological disease, researchers believe.

Researchers analyzed the medical records of more than 20 thousand people diagnosed with multiple sclerosis. The study found that people with multiple sclerosis c risk of cancer was 10% lower than in the control group. Experts suggest that the reason may be changes in lifestyle or treatment after receiving the diagnosis.

The effect was most apparent among women who are sick and incurable form of multiple sclerosis (MS). The disease may manifest itself outwardly moderate for some and cause permanent disability in others. RS - is an issue that has touched millions of people around the world. The study was published in the journal Neurology.

Artificial vein to replace the damaged vessels

A new model of peripheral circulatory system will help millions of patients with vascular disease. Scientists develop artificial vein for patients with circulatory problems. The device in the form of spiral vessels showed high efficacy in various clinical studies. The developers hope that their discovery will help surgeons to perform bypass surgery without the use of vessels of the patient. It was expected that the development of artificial vessels will help millions of people suffering from diseases of the peripheral arteries.

The disease begins when zhiropodobnoe material narrows the vessel lumen and impedes the flow of blood in the limbs. This can cause very serious problems with the limbs and in the most difficult case - her amputation. Artificial blood vessels, developed prior to this also suffered from sediments aterogennyh substances, so many surgeons prefer to use their own vessels Rights.

The researcher and the creator of a new type of vessels, Dr. Peter Stonebridge, found that the blood moves through the vessels is not direct, and vorticity, which helped him create a new model of artificial vessel - spiral. It is a new structure will help to avoid blocking the vessel, and thrombosis therein.

You can lose hearing from cotton pads

Drivers and passengers who are in an accident in the car, often become deaf. Cotton loud, resonant at the time of disclosure airbags, may cause long-term hearing loss for 17% of people. This conclusion, the results of several experiments, came to the American physiologist Richard Price. Scientist created the model of the human ear and subjected to its effects of different noise volume more than 130 decibels, which is comparable to the roar, which is audible at the runway during take-off man jet.

It was found that the cotton in the deployment of airbags, but lasts for a fraction of a second, no less loud, and thus very dangerous to your hearing. In passing, Price decided to test the hypothesis that in the closed windows of road noise damages the ear cushions worse than with the windows open because of the fact that in a closed car pressure above.

Physiologist is experimentally verified and found that all of the other way around: with windows closed cotton pillows less dangerous, despite the high blood pressure, which actually gives a shot of the inner ear ( "responsible" for damage to your hearing), but suffers in this way, middle ear and less harm. Price hopes that developers of security take into account the results of his work.

HANDBAGS cause pain in the neck

This conclusion came Jane Sadler, a practicing physician from Baylor Medical Center in Texas. According to the manual therapist more and more women who prefer big bags on the long strap, complaining of persistent headaches and pain in the neck. William Keizo, physiotherapist in private practice in Houston, Texas, adds that wearing these bags can cause problems with your back.

Since designers have proclaimed a new trend, doctors were more often women who have headaches and problems with the spine. Often, a large bag in which a woman goes to work, weighs three to four kilos. Allow such a weight - not the most useful employment for women. If the bag yet, and long belts, the burden is beginning to resemble a weight, loose on the women's fragile shoulder. Long belts increase the load, and then fashionable bag has become a serious threat to the health of the spine.

According to doctors, a heavy bag on his shoulder severely alters the normal situation of SARS. And this provokes dizziness and pain in the spine. Safe doctors recognized bags, weighing no more than two kilograms. Recall that in this season's actual bags of various sizes, from bulk to the smallest. The severity and conservatism is not in fashion, handbag must be unusual, fanciful painted. Their richly decorated with large paste, rivets, fringe, chains and brooches.
