New Tools Use Light To Turn Off Brain Cells And Possibly Treat Brain Disorders
Neuroscientists at the Massachusetts Institute of Technology have developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, they could potentially lead to new treatments for abnormal brain activity associated with disorders including chronic pain, epilepsy, brain injury and Parkinson’s disease…
Silencing brain cells with yellow and blue light
Neuroscientists have developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, they could potentially lead to new treatments for abnormal brain activity associated with disorders including chronic pain, epilepsy, brain injury and Parkinson’s disease.
Alternative Swine Flu Vaccination Provided By Insect Cells
Scientists in Vienna have developed a new technique for producing vaccines for H1N1, ’swine flu’, based on insect cells. The research, published in the Biotechnology Journal, reveals how influenza vaccines can be produced faster than through the traditional method of egg-based production, revealing a new strategy for the fight against influenza pandemics…
Natural Flu-Fighting Protein In Human Cells Discovered By Scientists
In findings that may lead to better ways to prevent and treat influenza and other viral infections, researchers report the discovery of a family of naturally occurring antiviral agents in human cells. In experiments in human and mouse cells, the flu-fighting proteins prevented or slowed most virus particles from infecting cells at the earliest stage in the virus lifecycle…
Transplanting People’s Own Stem Cells Into Heart Lessens Pain, Improves Ability To Walk
The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk. The transplant subjects also experienced fewer deaths than those who didn’t receive stem cells.
Your own stem cells can treat heart disease, study suggests
The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of patients with severe angina results in less pain and an improved ability to walk. They also experienced fewer deaths than those who didn’t receive stem cells. The stem cells were injected in an effort to spur the growth of small blood vessels in the heart muscle.
Mesoblast Limited (ASX:MSB) Proprietary Stem Cells Successfully Repair/Regenerate Damaged Intervertebral Disc Cartilage
Australia’s regenerative medicine company, Mesoblast Limited (ASX:MSB)(PINK:MBLTY), today announced highly successful preclinical trial results of its adult stem cells in the treatment of degenerative intervertebral disc disease, the leading cause of low back pain.
Cells Protected Against HIV Infection By Engineered Protein-Like Molecule
With the help of the human immunodeficiency virus (HIV) and molecular engineering, researchers have designed synthetic protein-like mimics convincing enough to interrupt unwanted biological conversations between cells. Interactions between proteins are fundamental to many biological processes, including some less-than-desirable ones like infections and tumor growth.
Peripheral Nerve Repair With Fat Precursor Cells Led To Wider Nerves And Less Muscle Atrophy
To determine if guided fat (adipose) precursor cells (APCs) could improve nerve regeneration and functional recovery, researchers at the University of Pittsburgh (USA) used biodegradable nerve guides to transplant APCs into the injured peripheral nerves of laboratory rats.
$1.7 Million Grant To Study Stem Cells In Intervertebral Discs Of The Spine Received By Jefferson
Scientists at Jefferson Medical College have received a five-year, $1.7 million National Institutes of Health grant funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases to study mechanisms regulating stem cell self-renewal and differentiation with the aim of regenerating diseased and painful intervertebral discs. A previous study by the same group showed that stem cells exist in both animal and human intervertebral discs.
