Effect of gamma irradiation on the overall quality of a commercial plain-type yogurt products.
This approval extends the permitted storage time for platelets to seven days with INTERCEPT treatment, compared to five days without treatment, and also allows INTERCEPT to be used in place of gamma irradiation for prevention of transfusion-associated graft versus host disease.
53BP1 foci were increased following gamma irradiation, consistent with expectations for cells requiring repair of radiation-induced DNA damage (23 and 32 foci/cell compared with approximately 1-2 or 2-4 foci/cell following sham exposure in fibroblasts and stem cells, respectively.) In contrast, 53BP1 foci were reduced in both cell types after exposure to 915-MHz GSM and 1947.4-MHz UMTS MWs (to < 1 foci/cell), whereas apparent effects of 905-MHz GSM were limited to stem cells only.

Conducted by research scientists from Clearant, Inc., a biotechnology company, and AlloSource, one of the nation's largest non-profit providers of human tissue allografts, the study is the first randomized, dose-dependent analysis to compare conventional low-dose gamma irradiation to Clearant's optimized, high-dose gamma irradiation method.
Because gamma irradiation does require radioactive compounds, there are valid environmental concerns about potential spills at these plants and during transportation.

Infected and uninfected Vero E6 cells were harvested 3 5 days after inoculation, inactivated by fixation and gamma irradiation (2 x [10.sup.6] rad), and processed for standard, immunolabeling electron microscopy (IEM) of ISH EM as previously described (6,14).
