At the highest dose given of 640mg the clusterin messenger RNA (mRNA) was down to a mean 8% level as compared to historical controls. The drug was well tolerated by patients. Said Dr. Chi: "We designed the Phase I trial in such a wa...

Cancer vaccine based on pathogenic listeria bacteria shows promise targeting metastases

...gulf them, so that they end up encased in a bubble within the body of the cell. The bacteria would be benign if they remained isolated in this compartment, because the cell can kill them there. But they are able to break out into the cell interior, the cytosol, and take over the host cell's machinery to spr...

'Most recent common ancestor' of all living humans surprisingly recent

These more realistic models estimate that the most recent common ancestor of mankind lived as recently as about 3,000 years ago, and the identical ancestors point was as recent as several thousand years ago. The paper sug...
