A sweet solution for Alzheimer's disease?

...on to the vaccine," the researcher said. Another complication with previous attempts to treat Alzheimer's disease has been that some compounds--such as beta secretase inhibitors--cannot enter the brain easily, St George-Hyslop explained.

The Mayo Clinic researchers believe current sepsis treatment isn't more effective because the theory of sepsis is too narrow. Current treatments don't target all causes of sepsis syndrome -- only the bacterial poison cause --...

Researchers develop portable 'vein finder' for faster, more accurate injections

...s Jim Larsen, a research engineer in EOSL. Another complication is that only a small amount of energy, about 1/10,000 of transmitted waves, scatters off the vein. "So you're limited in how much energy you can put in and how much you can pick up," he adds. "Cost, size and power issues restrict us to using a sing...

Defective immune system response to smallpox vaccine detailed in new study
