Scientists have confirmed the discovery of a new lethal virus in Africa

Rapidly developing life-threatening disease, the onset of which was recently adopted in South Africa, due to a new, unknown virus science. This is specified by a researcher at Columbia University, Ian Lipkin (Ian Lipkin), introduced genetic studies in South Africa performed the virus samples. Outbreak of the disease occurred, the symptoms are similar to hemorrhagic fever in the capital of South Africa, Johannesburg at the end of last month. His first victim was a resident of Zambia, who came to South Africa for treatment. Several later died Zambian paramedic who accompanied a woman, and after him - clean and nurse Johannesburg clinic in contact with the patient. Dead tissue samples were sent for analysis to the laboratory of the U.S. Centers for Disease Control. Lipkin, studies showed that the virus cause disease in Africans a previously unknown species of arenaviruses. It differs from a known cause of Lassa fever, also to the genus of the arenaviruses and has no relation to the agents of haemorrhagic fever Ebola and Marburg. The scientist said that the new virus infection can be treated with ribavirin. Currently, under the supervision of doctors in South Africa about 100 people were in contact with the victims of the virus.

U.S. 56 - year-old woman gave birth to my three grandchildren

11th Jas October Dalen Berg (Jaci Dalen Berg) was c-section at the Cleveland Clinic Hillcrest (Hillcrest Hospital). Born were three girls, two of whom are identical twins. Children more than two months premature birth and weighed less than 1400 grams per. But now their lives are not in danger, according to doctors. Hillcrest Clinic representatives said that suffer a mother of girls Kozeno Kim (Kim Coseno) and her husband of infertility and planned to adopt a child. But the mother of Kim agreed, Jas Dalen Berg, undergo the process of in vitro fertilization (IVF) and a surrogate mother for her grandchildren.

In Novgorod parents discovered alcohol in the formula

In Novgorod found eight-child parents that instead of the juice in a jar of baby food alcohol, reports RIA Novosti. She became suspicious when the child is trying to "juice" spat. Parents tried to drink himself and found the switch. For fear of the potential harm to the child's body, they called a team of "first aid". Getting doctors felt the baby happy, hospitalization was not required. According to parents, the Outer Banks was absolutely normal. As the employee "first" is the child's father, a doctor by profession, trial planning with vendors selling the "juice". About what companies in the alcohol-based formula not reported.

Massage can be used as an anesthetic

American doctors use massage as a means of relieving pain. The effect of a professional massage can last for several weeks, according to specialists. Probably not, there is hardly a single person who does not want a professional massage. Great feeling after a massage guaranteed. Massage is useful not only for healthy people who want to relax. Recently, physicians began to use massage to treat people with cancer. They found that a professional massage or a special back massage have a strong analgesic effect. Severe chronic pain - the eternal companion of cancer, especially in the last phase of the disease. Patients reported pain relief after the massage and effective pain reliever. The beneficial effects of massage remained for several weeks. The scientists could easily explain the analgesic effects of massage as a massage in the body increases the level of hormones "luck" of dopamine and serotonin, and reduces the amount of the stress hormone cortisol. These biochemical changes that increase the well-being and positively change people's attitudes to their illness and life in general.

Contact lenses can lead to blindness

Contact lenses increase the risk of infection by pathogenic microorganisms, leading to blindness, say Spanish scientists. Experts conducted a study in which a high percentage of contact lens was contaminated with Acanthamoeba microorganisms that can not be killed with conventional disinfectants. These microorganisms are one of the most common types of protozoa in soil and fresh water. Once in the eye, because it will carry amoebic keratitis infection, 85% of the morbidity, the people who contact lenses. Experts believe that such an infection in the long-run total blindness. Ameba commonly found in chlorinated pools and tap water, so that the people who wear contact lenses while swimming or rinsed with water containers lenses have an increased chance of infection. According to experts, has in the last twenty years amoebae increased in the world due to the fact that more and more people were selected for vision correction contact lenses. According to the Spanish microbiology at the University of La Laguna in the Canary Islands Pathogenic amoeba in tap water and feed on bacteria, always on the lens, "live" between it and the eye. The main reason for always keeping an eye infection - the lack of proper hygiene and proper care of the lenses.

Promote scientific vaccination to prevent cervical cancer

Could deliver the active immunization of older women against cervical cancer a devastating blow against the disease, according to U.S. scientists. According to experts, the active vaccine against cervical cancer could halve cases of the disease in women at the age of about 45 years. Using mathematical calculations, experts estimate that vaccination of women in the U.S. aged 12 to 45 years with cancer-causing HPV may reduce the incidence of cervical cancer by 85% for 12 year olds and up to 55% - for Women 45 years. It could also help to reduce the incidence from 34 to 67% for women 25 years. The calculations on a 100% vaccination of the female population that were based to implement in practice very difficult, experts said. Most cases of cervical cancer caused by the sexually transmitted human papillomavirus. Two U.S. companies have developed a vaccine against HPV types 16 and 18, which are known to cause 70% of cervical cancer cases. Experts hope that the majority of women to participate in the vaccination and avoid the occurrence of a serious illness.

Scientists have found the gene responsible for transsexual men

Australian scientists have a gene that regulates the production of testosterone and affects the transsexual man who wants to be a woman, reports the BBC identified. The researchers analyzed the DNA of 112 people who want to voluntarily change their sex. It was found that in these patients is probably a longer version of the androgen receptor gene may be. The genetic difference may cause a mild reaction to testosterone, the scientists believe. The study, published in Biological Psychiatry. There is a social stigma that transsexualism - show a lifestyle choice, but the results of the study, said that the biological properties of a larger influence on the identification of sexual preference, author of the study - Professor Vincent Harley.

Doctors often use a placebo instead of a few drugs

Many American doctors give their patients a placebo or simply "dummy" instead of certain drugs, such as a pain reliever. And doctors believe that treatment is the illusion created quite ethical, Reuters reported. The researchers found that of 679 ambulances half of patients treated with placebo, and does not want to say. The idea is to perform a "placebo effect" - improving health through psychological effects that lead to the expectation of a positive effect of the fact that people feel the change in the physical layer. More than 60% of doctors believe that a placebo in patients is quite possible, the researchers reported. However, such acts are contrary to the standards established by the American Medical Association (AMA), which means that the use of placebo in the treatment unethical States. The study experts found that in fact some of the patients on placebo had a positive impact. Nevertheless, representatives of the AMA believes that the placebo may be used only with the consent of the patient, or it may seriously undermine the confidence of the actions of health care professionals.

Man's face can be determined by physical force

Can in the face of people learn how much he is physically strong, say psychologists from the University of California at Santa Barbara. Scientists conducted an experiment in which invited participants to the physical abilities, only photos of his face and upper body base were assessed. Before the demonstration images, all study participants were physically examined. It was found that guinea pigs to photograph just managed to show the true strength of the men. It was also found that the thickness of a human person to evaluate not muscularity feet based and tilt on the basis of the width of the breast, and biceps. But as far as physical strength of women, none of the participants in the study is not able to identify the faces of the beautiful half of humanity. According to experts, has these capabilities assessment of physical violence. Originated in ancient times, but different roles for men and women Men unconsciously the degree of risk that it is a man, and men like the women take to protect them and their offspring.

Scientists have learned how to selectively erase memory

Scientists from the U.S. and China have worked together, learned what to selectively erase memory in mice. Previously researchers have an enzyme CaMKII ones found an important role in the regulation of the formation of memory in the brain. Now experts have developed a method of regulating the activity of this enzyme. It was found that forgetting an increased activity of CaMKII leads the objects seen in the last few hours, and the fear experienced in recent months. But the memory of the other earlier events not suffering. According to experts, the opening will allow the use of a new method for the treatment of people who have a lot of stress, and to get rid of fighters from anxiety and related depression.

Scientists have found changes in the brain of suicide

The brains of people who committed suicide, found chemicals, from those who were in the dead for other reasons people reported Canadian scientists found differ. The researchers studied 20 samples of brain tissue of dead people and those who have committed suicide. It was found that a variety of factors surrounding the brain of suicide victims and what. Specific processes that influence the behavior The study was published in Biological Psychology. Scientists believe that genetic factors interact with those around us and factors lead to certain long-term changes in the brain. This is a very important discovery, experts say, because such phenomena not previously connected. Scientists from Carleton University in Ottawa, studied the brain tissue of 10 people. Severe depression and committed suicide, and suffered the 10 people who died of other causes It was found that the DNA of people in group suicides changed its chemical composition by a process of methylation. Rate of methylation in suicides was almost 10 times higher than in the control group, the blocking of the gene out that an important role in the regulation of human behavior. What changes in behavior, namely the development of suicidality. Experts suspect that the cause of a prolonged and severe depression and other psychological problems phenomena that are influenced by the environment and the diversity of human experience.

Scientists have derived a new tomato variety that protect against cancer

Scientists have inferred type purple tomatoes that will be able to able to prevent the occurrence of cancer, reports the BBC. Specialists suggest that fruits rich in antioxidant enzyme anthocyanin, have protective properties of the formation and development of cancer. Scientists have created a tomato with genes from snapdragon flower, which contains a large amount of anthocyanin. The study was published in the journal Nature Biotechnology. Scientists conducted an experiment, which means that mice that ate as tomatoes lived longer found. Can probably altered nutritional impact on human health and life expectancy. The high content of anthocyanins in berries, blackberries, cranberries, chokeberry, and the study found, helped slow the growth of colon cancer cells. Also, experts believe that. Food enzyme anthocyanin, a protective effect against cardiovascular disease and age-related degenerative diseases There is speculation that the enzyme enhances the visual acuity and preventing obesity and diabetes. Scientists continue the positive properties of fruits and vegetables, examine the effect upon human health.

Standards of care is a duty

Ministry of Health developed. For all regions of the Russian Federation standards and procedures for the care that will be in contrast to the reports currently in operation, binding, AMI-TASS The statement has been appointed director of the department of medical care and health development Olga Krivonos. "Before treatment standards were advisory in nature, they are now mandatory," - said Krivonos. According to her, the same changes will occur and the sequence of care. Since 2004, the Ministry of Health over 600 standards of medical care, advice had been published. Based on federal standards published their own regions, which may differ. "We are currently planning to bring everything to a common denominator, because the quality of care should be equivalent, in what corner of our country was a man," - said Krivonos. Standard treatment provides for the necessary medical manipulation, the use of certain medications, surgery and other treatments. Procedures for the provision of medical care to the list of devices, the number of employees in the stores, the number of patients who go to the doctor, etc. until the end of 2008 to develop the Ministry of Health is planning standards and procedures for emergency medical care . determine Next, a single regulatory framework documents will be developed for other services. Plans in the process of implementing new standards Ministry to increase the level of regional institutions into a single baseline, added Krivonos.

Swedish scientists believe unjustified prosecution of HIV

Swedish government institution has refused. The police with information about HIV-positive, to infect, women suspected Under Swedish law an HIV-positive person who knowingly unprotected sexual contact with a healthy person is 1-10 years in prison. Refused, however, the Swedish Institute for Infectious Diseases of the police information about HIV-positive, which is suspected of infecting women to give. A leading specialist and regional manager Ian Albert Institute (Jan Albert) explained that from now believes in the organization that HIV infection is not considered a crime, and that everyone needs to understand the risks of unprotected sex put together. Director Ragnar Norrby (Ragnar Norrby) added that work on the criminalization of HIV prevention is difficult, and that the punishment is too harsh for an infection. Furthermore, the development of antiretroviral drugs has made HIV as a multiple.

May be in the UK to create embryos that are a mix of human and animal

In Britain, the bill of the lower house of parliament adopted in the third reading, allowing the creation of hybrid or chimera embryos, reports The Guardian. The procedure for the adoption of the bill was not completed because the need is the approval of the House of Lords. And if the House of Lords to take a decision in the affirmative, then the creation of chimeras in the UK can be approved in November 2008. Experts reported that embryos of chimeras, which are a mix of human and animal can be called a source of stem cells. To remove them from the egg to create mammalian core containing the genetic material of the organism, and instead put the core of a person. As a result, the resulting embryo is not quite human, because its cells will hold a part of the parent animal.

Gases from the intestines the basis for new drugs to treat high blood pressure

Gas is discharged from the intestine can not only spoil the smell of the air, but also have an effect on blood pressure, U.S. researchers reported. A small amount of hydrogen sulphide - a toxic gas produced by bacteria living in the human gut, is the cause of bad breath. Scientists conducted an experiment in mice, so that the gas also showed CSE enzymes produced in the blood vessels, causing blood vessels to expand and lowers blood pressure. According to the authors, this discovery will allow to develop new treatments for patients with blood pressure problems. Experts plan further work in this area. The study was published in the journal Science.

American smokers protivopnevmokokkovuyu recommends vaccination

The renowned U.S. expert committee found it necessary to recommend a specific vaccine American smokers. To vaccinate caused According to the Advisory Committee on Immunization, with smoking Americans against pneumococcal disease, pneumonia, meningitis and other diseases. Typically Advisory Committee recommendations of the U.S. authorities, so it is likely that there will soon receive additional vaccines 31 million American smokers. According to statistical studies smokers are four times more likely to get pneumonia as a Non smoking. This is probably due to the fact that the tissue changes caused by smoking and lung airways causing their vulnerability to germs. Advisory Committee on Vaccination supported the decision to recommend vaccination for smokers to eleven votes to three, with one abstention. At the same time, some experts say that the most cost-smokers be vaccinated at the age of 40 years, as young people are victims of pneumococcal infections are relatively rare. Currently in the United States for use approved two vaccines against pneumococcal disease: The first recommended protects against 32 strains of pneumococcal bacteria for adults over 65, and the second, which protects against the most common strains of 7, for children under the age to vaccinate two years. At the same meeting, the Committee on the vaccination against anthrax in the event of terrorist attacks pregnant recommend refused the vaccination of children was considered acceptable by the scale bioterrorist threat.

Medications contribute to weight reduction, the development of mental disorders and suicide

European group to monitor the drug is recommended to combat the use of drugs for obesity and Rimonabant Acomplia, as they cause severe psychological problems and even increase the risk of suicide to abandon, reports the BBC. Representatives of the European Medicines Agency (EMEA) said that it is necessary to the promotion of these products for as long as it was clearly not suspend its effects on the human psyche. Patients should not take the medication abruptly interrupt his treatment, they should discuss this with your doctor, experts say. In the UK, about 97 thousand people are overweight or obese. Over 20 thousand people at the time, one of these drugs. Taking the drug rimonabant was approved by the EMEA in June. In July last year, already a warning of the EMEA, can cause depression and mental health problems Acomplia character has received. Experts also recommend not to prescribe these drugs to people with symptoms of depression or taking antidepressants. The second study showed that increasing the intake of rimonabant the risk of mental disorders compared with placebo twice. According to researchers in the period from June to August 2008, five cases of suicide in patients who reported in the experiment and drugs, compared with a case of suicide in the control group. Experts plan further studies on the influence of drugs to combat obesity.

Scientists have found a way to prolong life

New technology to the basic functions of the human body that support developed by scientists from the Institute of Bioregulation and Gerontology, St. Petersburg. A unique method is based on peptides that penetrate directly due to the low mass and size to stimulate the cells into the damaged tissue and makes the production of these essential proteins. Scientists believe that we can be very helpful to others at the turn of evolution, in which the elderly are more beneficial to society than are young, because of the experience and knowledge. According to experts, the genetic species Homo sapiens is the life of 110 to 120 years. Maximum age in the Guinness Book of Records, it was possible to a certain Frenchwoman to reach the dead in 122 years. The remaining records of this type not documented, experts say.

The crisis forced the Americans to save the treatment

The crisis in the U.S. economy has led many Americans to medicines and recommended medical procedures to deny reports Fox News. Experts believe that in the future this trend will inevitably lead to a rise in the number of patients that carry a long-term and expensive treatment. After the telephone survey conducted by a physician Kaiser Family Foundation, the number of Americans who said that they or their relatives were forced to retreat from certain types of treatment for financial reasons, has increased from 29 to 36 percent. About a third of respondents had not been recommended by the studies or procedures, with a fifth of them admitted that the refusal to treat their condition deteriorates. Another wake-up call to reduce the number of prescriptions is the first time in 12 years fell by 0.4 percent. In addition, after the unification of the financial management of health care facilities in U.S. hospitals by 1-2 percentage reduces the number of unnecessary medical procedures - in recent years, their numbers increased by 3-4 percent annually. At the same time, the U.S. health care facilities there is an influx of patients in need of assistance, especially for patients who have no health insurance. According to representatives of the American Hospital Association, in the future the number of such applications can be significantly increased.
