Until now, the beta unit appeared to be a boring linker that simply held the three subunits together, according to Milbrandt. Instead, Dasgupta and Milbrandt discovered that the beta subunit was determining where AMPK did its job. AMPK with one version of the subunit, beta 1, was discovered both in the nucleus of cells and in the physical body of the cell, which is called the cytoplasm. They demonstrated that whenever activated AMPK enters the nucleus of stem cells, it inactivates the retinoblastoma protein, a grasp regulator of cell reproduction. This enables neural stem cells to survive and proliferate.

Statistical Analysis Efficacy analyses were performed according to the intention-to-treat principle. In sufferers with multiple events, the earliest end stage was counted. Chances ratios with 95 percent confidence intervals were calculated. Logistic-regression models tested for conversation with study-group assignments in chosen subgroups. Safety end factors were summarized for the as-treated human population . The original sample size provided a power of 85 percent to detect a 22.5 percent relative reduction in the rate of the principal efficacy end stage in the early-eptifibatide group, as compared with the delayed-eptifibatide group, assuming a 96-hour event rate of 5.8 percent in the latter group.
