Intestinal bacteria are accused of spreading resistance to antibiotics

As Xinhua notes, scientists from the University of Arizona and the Norwegian University of Sciences have studied bacteria that live in the intestine of honey bees. The scientists have found that genes for an antibiotic resistance were spread in the bacteria community so that all bacteria without exceptions became resistant.

Discovery: genes start mutating soon after conception

According to a new study carried out by scientists of Yale University and the Mayo Clinic, hundreds of small genetic mutations start mutating in the cells of the embryo after conception. Many of these mutations occur in the embryo when sex cells are formed. This means that these mutations can become a part of the genome and be transmitted to the next generation, reports.

Genetics have told how many mutations the human’s brain accumulates during the life

As notes, scientists of Yale University and Harvard have calculated how many mutations the human’s brain accumulates during the life. The scientists have studied both embryos and adults. The experts from Yale have evaluated the dynamics of mutations in embryos. DNA analysis has shown that young neurons contain 200 to 400 genetic variations scattered along the whole DNA chain.

American scientists have discovered a new method to enhance the effect of antibiotics

This method of the Massachusetts Institute of Technology and Harvard University is able to cure even the most antibiotic resistant bacterial infections, Xinhua reports. In particular, the scientists were interested in increasing the sensitivity of pathogens to quinolones (antibiotics are often used to treat infections caused by Escherichia coli and Staphylococcus aureus).

Treatment of sleep apnea relieves epileptic seizures

CIPAP therapy is a method of sleep apnea treatment by means of artificial ventilation with constant positive pressure. Scientists of Cleveland Clinic have found that CIPAP therapy is useful for people with epilepsy suffering from sleep apnea. Due to this therapy, the number of epileptic seizures is reduced, reports.

Scientists have found that HIV very quickly affects the brain,

It has long been known that HIV-positive people often face problems such as depression and forgetfulness. However, until now, scientists did not know whether this is a consequence of somatic diseases of these people, or the virus is able to affect the brain directly.

The brain surgery will be safer with

The needle was designed by Australian scientists. It has a tiny fiber-optic camera that helps surgeons during the surgery to see what vessels are at risk and to prevent their damage. It is interesting that namely computer detects the threat and notifies surgeons about it, Business Standard reports.

By means of one drop of blood, a simple test may detect cancer

Only a drop of blood is required for a new test detecting 30-40 biomarkers of the disease. Results can be received within 24 hours. This method will change the diagnosis of bowel cancer. As The Daily Mail notes, some patients will not be subjected to unpleasant and dangerous colonoscopy any more.

Cancer drugs may help to control blood pressure

Researchers from Georgetown University say that drugs suppressing the growth of cancer tumors also affect blood pressure. These are fibroblast growth factor inhibitors involved in angiogenesis (new blood vessels formation).

Genetics have shown the place in the genome where all allergic reactions are associated

Scientists have identified more than 100 genes acting as risk factors for severe allergic reactions, hay fever, eczema and asthma, Zee News reports. Earlier, it has been already established that these ailments have a single genetic basis. However, geneticists did not know where the problem genes affecting the functioning of the immune system exactly were.
