TANGO: towards faster prognosis of Alzheimer's and Parkinson's diseases?

... environmental factors - to indicate the degree of probability that particular proteins will stick together. TANGO thus opens possibilities for new diagnostic techniques for diseases that are caused by proteins that stick together erroneously.

Genes can influence both alcohol consumption and dependence

... three times studied, was associated with a higher probability of alcohol dependence at some time in a person's life. The association was mainly due to genetic effects on both alcohol intake and alcohol dependence, but our results also show that while some genes affect both intake and dependence, others affect ...

The telomere crisis: A crucial stage in breast cancer

...mmary cell culture studies also confirmed that the probability of successful passage through the telomere crisis is low -- most cells damaged because of shortened telomeres can't evade cell death. In fact, women with usual ductal hyperplasia are only slightly more at risk of developing invasive cancer. When carc...

The Risk-EOS burn scar mapping service began last year. The intention is to develop further fire-related services by the end of 2007, including daily risk maps combining...

Microscopy scans show how brain cells process energy

...ire nature of multiphoton microscopy increases the probability that two or three photons will interact with individual biological molecules at the same time, combining their energies. The cumulative effect is the equivalent of delivering one photon with twice the energy (half the wavelength, in the case of two-p...

Tracking cystic fibrosis with mice

The genetically modified mice will be used by the researchers for further studies. The mice can be used to test how the illness originates, what other factors are involved and wh...

Phytoplankton may stimulate uptake of CO2

So it seems logical that iron-fertilized, low silicate waters might not be as efficient carbon sinks as iron-fertilized high silica waters, but the results of this study disproved that idea ...

The CARB analysis shows that the probability of a modern intron's presence in an ancestral gene common to the genes studied is roughly 1 percent, indicating that the vast majority of today's introns appeared subsequent to the origin of the genes.
