31.01.2017 Scientists have found a new method to treat Alzheimer's disease
A targeting effect on tau protein tangles in mice with symptoms similar to Alzheimer's disease allowed to reverse the brain damage, slow down the memory loss and increase the lifespan of rodents, New Scientist reports. It is known that two kinds of deposits of sticky proteins such as beta-amyloid deposits and tau protein tangles are observed in the brains of people with Alzheimer's disease.
30.01.2017 Scientists have found out why diabetics have the increased risk of Alzheimer's disease
According to scientists, cholesterol is necessary for the normal brain activity. But due to diabetes the brain cholesterol concentrations can be reduced. This is proved by experiments in mice. The scientists suppressed cholesterol production in the brain in rodents. After that, neurological disorders have appeared in the animals, Medical Xpress reports.
27.01.2017 After birth brain scans determines the risk of developmental disorders in premature infants
Cerebral hypoxia is one of the most common brain pathologies in premature infants, which damages white matter. White matter consists of fibers that connect different parts of the brain. The damaged white matter disturbs the signal transmission inside the brain and between the brain and other organs.
25.01.2017 Scientists have found a new recipe against supergerms
The scientists of the University of Oregon have revealed a molecule which is capable to neutralize the bacteria resistance to antibiotics, Xinhua reports. This molecule is known as PPMO (phosphorodiamidate morpholino oligomer). It inhibits the activity of NDM-1 enzyme which makes the bacteria resistant to penicillin.
24.01.2017 Doctors: some people just need to take Vitamin E
Most of all Vitamin E is needed for the people with metabolic syndrome. This vitamin is an antioxidant and it is essential for the protection of cells, Xinhua reports. Metabolic syndrome can include several specific diseases or abnormalities, such as: abdominal obesity, increased blood lipids, high blood pressure, inflammation, thrombosis, insulin resistance or impaired glucose tolerance.
23.01.2017 Scientists are on the verge of development of new treatments for peripheral neuropathy
Peripheral neuropathy is the result of peripheral nerve damage. Symptoms vary from numbness, tingling, muscle weakness to severe pain, paralysis, and organ dysfunction. Peripheral neuropathy often develops in diabetics and people with HIV. Scientists of the University of California have carried out experiments with cells and rodents suffering from peripheral neuropathy associated with diabetes of the 1st, 2nd type, chemotherapy and HIV, Medical Xpress reports.
20.01.2017 Discovery: a concussion and Alzheimer's disease are closely related
Hitherto, doctors believed that severe traumatic brain injury is one of the key risk factors for the development of neurodegenerative diseases. But a new study conducted in the School of Medicine at Boston University, has shown that even mild brain concussion can lead to negative consequences, The Daily Mail reports.
20.01.2017 Experts have approached to creation of a cure for Autism
Researchers from the University of California have discovered a new biomarker in the EEG in children with autism spectrum disorder (ASD), suffering from Dup15q syndrome. The reason of Dup15q syndrome is a duplication of the section of 15th chromosome. This is one of the most common genetic abnormalities associated with ASD, Medical Xpress reports.
18.01.2017 Researchers have approached to creation of a new vaccine against tuberculosis
According to scientists, biogranules are used for the delivery of Mycobacterium tuberculosis antigens (Mycobacterium tuberculosis or Mycobacterium bovis). They are natural polyesters, created by a non-tubercular bacterium (E. coli), UPI.com reports.
16.01.2017 Neuroscientists say that the brain’s protection has a limited "useful time".
British scientists have revealed that the brain's immune cells are updated only six times during the human lifetime. According to the experts, this discovery will allow them to cope with neurodegenerative diseases, "Pravda.RU" writes. In the center of the study were phagocytes which absorb the dead or damaged neurons, as well as fight with foreign elements.
