12.   In PCR, researchers test several distinct genes with sequences that can vary slightly from person to person.

13.   More than half a century ago researchers tested gamblers who claimed they could affect the roll of dice.

14.   Not only have the researchers tested more patients, but they have fresh genetic analysis of the virus that firmly establishes it as a newly discovered type of herpes.

15.   Now researchers are testing the effectiveness of anti-inflammatories and estrogen in slowing or preventing the disease.

16.   Other researchers are testing vegF coated with membranes, or inside a virus that has been crippled so it will not cause illness.

17.   Oxidation damage may also play a role, so researchers are testing anti-oxidants such as vitamin E and gingko biloba.
