Big differences in duplicated DNA distinguish chimp and human genomes

...an developmental disorders such as spinal muscular atrophy and Prader-Willi syndrome. Parts of those duplicated segments have only single copies in the chimp genome, and it is possible that the chimpanzee is therefore not predisposed to the same diseases as a human. About two-thirds of human-only duplicatio...

U of MN researchers reverse memory loss in mice

...d memory loss that worsens over time and had brain atrophy similar to what a person with Alzheimer's disease goes through. The researchers further designed the mice so that the transgene that causes these symptoms could be "turned off." Transgenes are genes from one organism that have been incorporated into ...

Meditation associated with structural changes in brain

...nce that mediation may slow down the aging-related atrophy of certain areas of the brain." Studies have shown that mediation can produce alterations in brain activity, and meditation practitioners have described changes in mental function that last long after actual meditation ceases, implying long-term ef...

Memory loss affects more of the brain than previously thought

...tural changes alone have shown evidence that brain atrophy in the earliest stages of AD tends to be restricted to the temporal lobe, a region critical to long-term memory formation. "Involvement of both the frontal and temporal lobes in the earliest stages of AD suggests the possibility of a breakdown in th...

Injection may prevent infertility in men receiving cancer chemotherapy

...of the testes of Taxol-injected mice showed severe atrophy and empty seminiferous tubules, where the sperm-producing cells are contained", said Mr. Carmely. "In contrast, we saw only minimal testicular damage in the group that had previously been injected with AS101, and we could also find mature sperm. Inj...

A sweet solution for Alzheimer's disease?

...ry tangles. The brain becomes inflamed and neurons atrophy and die. It's not completely clear what kind of amyloid â peptide (monomers, oligomeric aggregates, or fibrillar aggregates) is responsible for the onset of disease, said St George-Hyslop of the University of Toronto. "Because we were able to show th...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

...ncourage reverse remodelling of the heart, prevent atrophy and prevent the heart from shrinking beyond its desirable size. The drugs used were lisinopril, carvedilol, spironolactone and losartan in the first stage of treatment and bisoprolol and clenbuterol in the second. The next step for the researchers...
