Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson’s disease. This discovery not only may explain how a genetic mutation linked to Parkinson’s causes the cells’ death, but could also open the door to new therapeutic approaches for the malady.

A combination of nutrients called NT-020 promoted adult neural stem cell proliferation in aged rats and boosted their memory performance, reported University of South Florida researchers studying natural therapeutic approaches to promoting the health of neurons in the aging brain. Researchers from the USF Department of Neurosurgery and Brain Repair tested two groups of aged laboratory rats; one group received NT-020 and another, the control group, did not. In the NT-020 group, the process by which neurons are generated -- called neurogenesis -- increased.

If mice are administered an antibiotic for three days and are simultaneously infected with malaria, no parasites appear in the blood and life-threatening disease is averted. In addition, the animals treated in this manner also develop robust, long-term immunity against subsequent infections.

In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of The Journal of Neuroscience. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake.

The landmark discovery found that injection of an agent called 'ADAC', activates adenosine receptors in cochlear tissues, resulting in recovery of hearing function. The finding paves the way for effective non-surgical therapies to restore hearing loss after noise-induced injury.

Progress toward understanding the role of sex hormones in the growth of prostate cancer—the most common cancer in U.S. men—has been hindered by the lack of a suitable laboratory research model. Now researchers say they have developed the first model of hormone-induced human prostate cancer initiation and progression.

The vitamin folate appears to promote healing in damaged rat spinal cord tissue by triggering a change in DNA, according to a laboratory study funded by the National Institutes of Health.  The researchers showed that the healing effects of the vitamin increased with the dosage, until regrowth of the damaged tissue reached a maximum level.

Dr. Kelvin Jones is looking at exercise as a new way to slow the degenerative processes of ALS, commonly known as Lou Gehrig’s disease.  Jones, a recipient of a 2009 ALS Canada Discovery Grant, has been pioneering research in this field for four years, using mice genetically altered to present familial ALS. He’s found that exercise has a positive impact on the mice, slowing the disease significantly.
