A small clinical trial of patients with multiple sclerosis (MS) who did not respond to interferon alone found that adding the human antibody daclizumab improved patient outcome. Patients who received the combined therapy had a 78 percent reduction in new brain lesions and a 70 percent reduction in total lesions, along with other significant clinical improvements. The trial was led by investigators at the National Institute of Neurological Disorders and Stroke (NINDS), a component of the National Institutes of Health. Findings will appear in the Early Edition of the Proceedings of the National Academy of Sciences1 the week of May 24-28, 2004.
MS is a chronic disease marked by inflammation in the central nervous system and development of lesions in the brain. Messages from the brain to the body are interrupted as nerve fibers begin to lose their protective coating of myelin, resulting in muscle weakness, problems with vision and coordination, pain, and, in some patients, cognitive impairments. Approximately 250,000 to 350,000 people in the United States suffer from MS and about 200 new cases are diagnosed by physicians each week. There is no cure for the disorder.
NINDS investigator Roland Martin, M.D., and colleagues studied 11 patients with either relapsing-remitting2 or secondary progressive3 MS. Each patient was treated with beta interferon - a naturally occurring antiviral protein commonly used to treat MS. Patients also received 7 treatments of daclizumab (a genetically engineered human antibody that blocks the interleukin-2 receptor on immune cells) administered intravenously at 2-week, and later, 4-week intervals.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
