While Mr. Yin blamed "underground and illegal plasma collection stations" for H.I.V.'s spread, he did not mention that many of these stations were owned or operated in collaboration with government bureaus, including the Chinese military.
These focal areas are hypothesized to be where previous commercial plasma collection stations were located.
Infections peaked in the surrounding counties in subsequent years, suggesting that commercial plasma collection stations branched out to those areas.
Some collectors established commercial plasma collection stations and, after collecting whole blood, removed the plasma and returned pooled red blood cells from blood type-matched donors so that donors could donate more often without becoming anemic [1], [2].
Alternatively, it is possible that commercial plasma collection stations were already widespread but that HIV first entered the ones that adhered the least to blood-borne pathogen precautions A number of studies have analyzed the natural history of HIV infection and estimated the time from seroconversion to death, ranging from 7.5 12.6 years in different populations [27] [33].
As recalled, lots of plasma collection stations were established in different regions before 1995.
So far, the 1,000- to 1,800-square-foot "clubs" — with plasma TVs, listening stations, a "mocktail" lounge and dance floors — are on 15 of the line's 21 ships.
Magnum-PSI consists of several subsystems including vacuum, cooling, plasma source, target station, and a number of diagnostic systems.
These results identify some design features for a prospective plasma material test station and the research required for this plasma source.
