Break through in the treatment of bacterial meningitis

It can take just hours after the symptoms appear for someone to die from bacterial meningitis. Now, after years of research, experts at The University of Nottingham have finally discovered how the deadly meningococcal bacteria is able to break through the body's natural defence mechanism and attack the brain.

Discovery of pathway that reactivate myelin repair

UMDNJ researchers have identified a key pathway that could lead to new therapies to repair nerve cells' protective coating stripped away as a result of autoimmune diseases such as Multiple Sclerosis (MS). An article reporting their findings will appear in the May 13 online edition of the Journal of Neuroscience.

DHEA supplement combined with vitamin D and calcium significantly improves spinal bone density in older women

"The results of our study are very promising. Similar studies have demonstrated much smaller benefits for bone than we found. However, calcium and vitamin D deficiencies, which are present in half of older adults, may have prevented DHEA from improving bone density in the earlier studies," said Edward Weiss, Ph.D., associate professor of nutrition and dietetics at Saint Louis University's Doisy College of Health Sciences and lead author of the study.
