The system, which is used in glasses, based on the technology of the so-called cloud computing and wireless connection to the Internet. Right on the glasses are a special Mini-Cams, whose main task - to send photographed images to a special remote service. At this service all the received video information is analyzed and then orally transferred to the owner points. It is planned in the coming years to run these points in the mass production

On the futility of the use of antibiotics for sinusitis

American scientists recently announced that the antibiotics by doctors appointed for acute sinusitis did not lead to the recovery of the patient. Different types of sinusitis - is, as explained by experts, and complications of infectious diseases affecting the upper respiratory tract. Today in medicine for this disease in most cases, doctors prescribe drugs with antibacterial properties.

The staff at Washington University in St. Louis (Missouri) conducted a study of 166 patients suffering from acute sinusitis, which enlisted the help of professionals. One group of patients was assigned to a course of antibiotics (10 days), and another - a placebo. All participants were allowed to experiment on the need to use drugs to facilitate such symptoms as pain, aching, fever, cough and nasal congestion. The researchers assessed the patients on the third, fifth, seventh and tenth days later disease.

Significant difference between the two groups of patients state scientists could not be detected. On the seventh day, participants who received an antibiotic, there were some improvements, but the difference was not the health of so palpable that you can talk about important changes from a clinical point of view. Also, there was no difference between groups in subsequent days. Based on the results of research, scientists have strongly recommended not to use antibiotics in the treatment of acute sinusitis forms.

Found antigens that will win salmonella

An international team of immunologists at UC Davis (University of California at Davis) has taken an important step towards developing an effective vaccine against salmonella - bacteria resistant to antibiotics, which is one of the main causes of foodborne illness throughout the world and blamed for the deaths of hundreds of thousands writes Medical Xpress.

They found a set of antigens (substances that cause an immune response), which is identical in mice and humans. "The identified antigens provide the basis for developing a vaccine against salmonella," - says immunologist Steven McSorley of the Center for Comparative Medicine (UC Davis Center for Comparative Medicine), who has been studying diseases that affect animals and humans.

At present there is no vaccine against strains of Salmonella. In addition, the bacteria salmonella are increasingly becoming resistant to antibiotics, which are actively used in the treatment, but new drugs acting on the horizon is not visible. "Despite the fact that infections caused by salmonella, play an important role in human health and animal antigens, which are key in developing a vaccine has not yet been identified," - commented S.Maksorli.

In order to detect these antigens has gathered a team of scientists, "collection" of the 2700 proteins, representing about 60% of all proteins produced by Salmonella. The experts found that 117 of them behave as antigens when mixed with the blood of mice infected with salmonella, and produce an immune response to protect against bacterial infection. 14 of these proteins were identical in all four strains examined in this study. Experts have also identified 14 proteins that serve as antigens in the blood of Malawian children infected with salmonella, 8 of these 14 proteins (57%) of 117 antigens were found in mice.

According to WHO, each year more than 1 million cases occurring in the United States, last year claimed the lives of 580 salmonella Americans. In Russia there are no clear statistics of cases. By some estimates, each year become ill with salmonellosis 30-40 people per 100 thousand population.

Cats can spread schizophrenia

The parasite that lives in the cat's body, once in the human body, can cause schizophrenia, says a scientist from the Czech Republic Jaroslav Flegrei. We are talking about Toxoplasma, dwelling in the intestines of cats. Previously it was known that Toxoplasma suppresses the human immune system and is especially dangerous during pregnancy. You can become infected without even having a cat at home, says the scientist.

Cat feces can get into water or soil, where the parasite lives for a while, then it may be in the body of rodents and cattle from which meat is roasted a bad infection transmitted to humans. According Flegrei, the parasite Toxoplasma organism found in 55% French, 22% of Americans and 10-20% of Britons, and this explains the reckless behavior of many people. Once in the brain, the parasite disrupt the locomotor system, the mechanisms of perception and behavior.
