Paralyzed man walks again after olfactory cell transplant, thanks to animal research

Today, almost 30 years after Prof. Geoffrey Raisman first identified their potential to repair nerve damage in mice, the BBC reports that olfactory ensheathing cell transplantation has been successfully used to enable Darek Fidyka, who was paralyzed from the chest down in a knife attack in 2010, to walk again. The paper reporting the transplant, … Continue reading Paralyzed man walks again after olfactory cell transplant, thanks to animal research

Stem cell therapy allows blind to see again, thanks to animal research

A team of scientists led by stem cell pioneer Professor Robert Lanza has reported today in the Lancet (1) the first evidence for the long-term safety of  retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs) in patients who took part in a trial undertaken in four centres in the US. substantial … Continue reading Stem cell therapy allows blind to see again, thanks to animal research

Nobel Prize 2014: Fortune favours the prepared mind

Speaking of Research congratulates John O’Keefe, May-Britt Moser and Edvard I. Moser on being awarded the 2014 Nobel Prize in Physiology or Medicine “for their discoveries of cells that constitute a positioning system in the brain”. By recording the activity of individual nerve cells within the brains of rats that were moving freely through their … Continue reading Nobel Prize 2014: Fortune favours the prepared mind

Kicking off a new era for neuroprosthetics, or just the warm-up?

Tonight, if everything goes according to plan, a young person will stand up in front of a global audience numbering in the hundreds of millions, walk a few paces, and kick a football.  This by itself may not seem remarkable, after all this is the opening ceremony of the World Cup, but for the Miguel … Continue reading Kicking off a new era for neuroprosthetics, or just the warm-up?

Ebola virus vaccine developed to protect wild gorillas and chimpanzees

The current Ebola virus outbreak in Guinea, Sierra Leone and Liberia is a stark reminder on the need for effective therapies and vaccines for this disease, which has claimed the lives of thousands of people in West Africa in a series of outbreaks since the 1970’s. It is not just the human inhabitants of West Africa … Continue reading Ebola virus vaccine developed to protect wild gorillas and chimpanzees

Spinal cord stimulation restores monkey’s ability to move paralysed hand

Today scientists at the Newcastle University Movement Laboratory announced that they have succeeded in restoring the ability to grasp and pull a lever with a paralysed hand using spinal cord stimulation. In a study undertaken in macaque monkeys they demonstrated for the first time that it is possible to restore voluntary movement in upper limb … Continue reading Spinal cord stimulation restores monkey’s ability to move paralysed hand

Paralysis breakthrough – electrical stimulation enables four paraplegic men to voluntarily move their legs

This weeks issue of the neuroscience journal Brain carries an unusual image; against a background of nerve activity traces a man lies on the ground, and as you scan down the images he lifts his right leg off the ground. For most people this might just be a simple warm-up exercise, but for Kent Stephenson it … Continue reading Paralysis breakthrough – electrical stimulation enables four paraplegic men to voluntarily move their legs

From clinic to mouse to clinic: New HIV gene therapy shows promise!

Yesterday a team of University of Pennsylvania researchers – led by Dr Pablo Tebas, Professor Carl June, and Dr Bruce Levine – announced the successful conclusion of a clinical trial to evaluate the safety of a new gene therapy technique for treating HIV. It is a result that may eventually allow millions of HIV positive … Continue reading From clinic to mouse to clinic: New HIV gene therapy shows promise!
