20.12.2017 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, UPI.com reports.
19.12.2017 Genetics have told how many mutations the human’s brain accumulates during the life
As Vesti.ru 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.
15.12.2017 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, UPI.com reports.
14.12.2017 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.
07.12.2017 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.
05.12.2017 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).
04.12.2017 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.
17.01.2018 Researchers have solved the problem of organ transplant rejection
The drug, which was originally intended to be used for the treatment of diabetes but never launched on the market, has found a new life. As The Daily Mail notes, scientists suggest to use it as a remedy for prevention of organ transplant rejection. According to statistics, every sixth patient dies after a heart transplant within a year. And the survivors have the increased risk of infection, weight gain, cancer and diabetes due to the need of using anti-immunity drugs for the rest of their lives.
30.11.2017 Scientists dispelled the myth of popular medicines against heartburn
Previous studies have shown that proton pump inhibitors, which are usually prescribed for heartburn and other acid-related diseases, increase the risk of developing dementia. But now experts have disproved this. According to The Deccan Chronicle, the researchers have analyzed the data of 3484 adults aged 65 and over.
28.11.2017 A new remedy may help to relieve chronic hepatitis
The developers have reported on the successful completion of Myrcludex B interim tests. Myrcludex B is a drug intended to patients with chronic hepatitis B (delta agent). As "Remedium" notes, the drug has been tested on 120 patients for 24 weeks. During that time the volunteers had no serious side effects. This proves the safety of the therapy.
