Researchers from several Russian institutes, including MIPT, have found out how prolonged exposure to ionizing radiation affects human stem cells. They discovered that it causes a cell cycle delay, which leads to faster repairs of radiation-induced DNA double-strand breaks, with fewer errors. It is unclear what the health implications are, particularly how this affects the...

Bacterial infection stresses hematopoietic stem cells
It has been thought that only immune cells would act as the line of defense during bacterial infection. However, recent research has revealed that hematopoietic stem cells, cells that create all other blood cells throughout an individual’s lifetime, are also able to respond to the infection. A collaboration between researchers from Japan and Switzerland found...

It’s not a rat’s race for human stem cells grafted to repair spinal cord injuries
More than one-and-a-half years after implantation, researchers at University of California San Diego School of Medicine and the San Diego Veterans Administration Medical Center report that human neural stem cells (NSCs) grafted into spinal cord injuries in laboratory rats displayed continued growth and maturity, with functional recovery beginning one year after grafting. The findings are...

Robotic Exoskeletons Show Promise As Tool to Help Kids with Cerebral Palsy Walk Easier
In the first clip, the boy appears to drag his feet as he walks, while his knees—particularly the left one—stay bent throughout his steps. In the second clip, his knees remain bowed inward. But his legs—now clad in a robotic exoskeleton—swing more as they move, and his feet lift off the ground and his knees...

Brain scan study adds to evidence that lower brain serotonin levels are linked to dementia
Results suggest serotonin loss may be a key player in cognitive decline, not just a side-effect of Alzheimer’s disease A brain showing decreases of serotonin transporters (blue) in the whole mild cognitive impairment group compared to the whole healthy control group. In a study looking at brain scans of people with mild loss of thought...

Scientists Use Light to Erase Unwanted Memories
Researchers at the University of California, Riverside have developed a technique to selectively erase fear memories by weakening connections between the nerve cells involved in forming such memories. Memories can be triggered by stimuli such as sights, sounds, and smells. Some memories are formed during traumatic events, and in this case stimuli associated with the...

Transcranial magnetic stimulation aids PTSD in eating disorders
(HealthDay)—Repetitive transcranial magnetic stimulation (rTMS) of the dorsomedial prefrontal cortex (DMPFC) seems to be beneficial for treatment of posttraumatic stress disorder (PTSD) in patients with eating disorders, according to research published online Aug. 16 in the International Journal of Eating Disorders. D. Blake Woodside, M.D., from the University Health Network in Toronto, and colleagues presented a...

Study suggests serotonin may worsen tinnitus
Millions of people suffer from the constant sensation of ringing or buzzing in the ears known as tinnitus, creating constant irritation for some and severe anxiety for others. Research by scientists at OHSU shows why a common antidepressant medication may worsen the condition. The study, to be published Aug. 22 in the journal Cell Reports, focused...
