Features of replication suggest viruses have common themes, vulnerabilities
...es observed by Ahlquist and his colleagues all had narrow necks that transcended the membrane of the organelle to the cytoplasm, the medium inside the cell and in which the organelle is suspended. The neck is a gateway that appears to permit substrates needed for replication to enter and newly made viral ge...No evidence that widely prescribed statins protect against prostate cancer

To study a narrow question − whether statin use reduces androgen concentrations in the blood − the researchers examined data from the Boston Area Community Health (BACH) survey, a population-based, NIH-sponsored, epidemiologic study.

... The dogs are known for intense breeding and their narrow gene pool, which makes them especially susceptible to diseases such as epilepsy, bleeding and cancers. However Gerber says that the findings in the present study are unique as infections with B. burgdorferi are not causing disease, whereas other bree...Chronic fatigue -- clues in the blood

Plaques can narrow the heart's arteries, allowing less blood to flow to the heart muscle (causing angina), and plaques that rupture may cause sudden heart attack, stroke or death.
