#Paralyzed man walks again using brain-computer link A brain-to-computer technology that can translate thoughts into leg movements has enabled a man paralyzed from the waist down by a spinal cord injury to become the first such patient to walk without the use of robotics,
doctors in California reported on Wednesday. The slow, halting first steps of the 28-year-old paraplegic were documented in a preliminary study published in The british-based Journal of Neuroengineering and Rehabilitation,
along with a Youtube video. The feat was accomplished using a system allowing the brain to bypass the injured spinal cord
and spinal injury victims regain some mobility. Dr. An Do, a study co-author, said clinical applications were many years away.

#Brain training app that could help schizophrenia sufferers live a normal life A new brain training app developed to help improve the memory of people with schizophrenia could save taxpayers thousands of pounds,
which found that schizophrenia patients who played the game regularly for a month were four times better at remembering these kinds of things than non-players.
Schizophrenia is estimated to cost £13. 1billion per year in total in the UK. The long-term mental health condition can cause a range of symptoms including hallucinations and delusions.

'Working with researchers at the University of New south wales, the team at Oxford analysed data from a patient trial where anti-retroviral therapy was interrupted at 48 weeks.
Anti-retroviral therapy has improved dramatically life-expectancy for people with HIV. Recent studies have advised patients should start the treatment

and young adults with rare blood disorders Hematology researchers have safely and effectively treated children and young adults for autoimmune blood disorders in a multicenter clinical trial.
In children with one of those conditions, autoimmune lymphoproliferative syndrome (ALPS), all the patients showed a durable, complete response, with normal blood cell counts and rapid improvements,
""Patients with ALPS and similar autoimmune disorders have had few long-term treatment options for managing their disease,
"said study leader David T. Teachey, M d.,a physician-researcher in hematology and oncology at The Children's Hospital of Philadelphia (CHOP)."
Collaborators from 15 medical centers contributed to the research; Teachey and Bride had study co-authors from four institutions.
ALPS is one of the autoimmune cytopenias, a group of diseases in which the immune system inappropriately destroys blood cells.
Patients may suffer anemia, uncontrolled bleeding and vulnerability to infections. Parents often see their children struggle with swollen lymph nodes, painful enlarged spleens, fatigue and anxiety.
Because autoimmune cytopenias are relatively rare, families often experience a"diagnostic odyssey"--years of testing,
bleeding and unsuccessful treatments before receiving an accurate diagnosis. Conventional treatment for autoimmune cytopenias uses corticosteroids to suppress the immune system.
Moreover, over the long term, corticosteroids increase the risk of osteoporosis and vulnerability to infection. The current study builds on preliminary results published by Teachey
and 12 others had caused secondary cytopenias by other underlying autoimmune diseases. All were intolerant of or resistant to corticosteroids.
Patients also had improvements in spleen and lymph node abnormalities. All 12 patients were able to discontinue steroids

In autoimmune diseases, the immune system turns against the body instead of protecting it. AGS is a rare genetic disorder that mainly affects the brain,

The same elegant system can trigger autoimmune disease when self-DNA is inappropriately present in the cytoplasm,
