[Q]: Context: Imatinib mesylate is a new drug that can inhibit the tyrosine kinase activity of Bcr-Abl, the receptors for platelet-derived growth factor receptor(PDGF) and stem cell factor, or c-kit. Chronic myeloid leukemia (CML) is distinguished by the presence of a reciprocal translocation between chromosomes 9 and 22 that results in a shortened chromosome 22, termed the Philadelphia(Ph) chromosome. As a result of the translocation, a fusion gene called the Bcr-Abl gene is created from two normal cellular genes, encoding a chimeric Bcr-Abl protein with a deregulated tyrosine kinase activity. The expression of Bcr-Abl tyrosine kinase has been shown to be necessary and sufficient for the transformed phenotype of CML cells. Imatinib can block the kinase activity of Bcr-Abl, thus inhibiting the proliferation of Ph-positive progenitors, and has shown activity against all phases of CML, though responses are most substantial and durable in patients in the chronic phase. An international phase III study which compared the efficacy of imatinib with that of interferon alpha combined with low-dose cytarabine in newly diagnosed chronic-phase CML showed the rate of major cytogenetic response at 24 months was 90%, including 82% of complete cytogenetic response. These results indicated that imatinib was superior to interferon-containing treatment as a first-line therapy. More than 10,000 patients worldwide, including those in Japan, have been treated with imatinib in clinical trials, and a lot of information has been accumulated on the use of this drug. The aim of this article is to review the use of this drug and the practical management of patients with chronic myeloid leukemia.
Question: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?
[A]: bcr-abl

[Q]: Context: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still.

[Q]: Context: Coming off their come-from-behind win over the Dolphins, the Broncos traveled to Arrowhead Stadium for an AFC West rematch with the Kansas City Chiefs. The Broncos jumped out to a 14-0 lead on their first two possessions in the first quarter, with quarterback Peyton Manning throwing a pair of touchdown passes a 23-yarder to wide receiver Demaryius Thomas and a 15-yarder to running back C. J. Anderson. A 22-yard field goal by placekicker Connor Barth increased the Broncos' lead to 17-0 early in the second quarter. The scoring play occurred after the Broncos' special teams fooled the Chiefs with a fake punt run by safety David Bruton and a fourth-down conversion by Anderson. The Chiefs got on the scoreboard later in the second quarter, with quarterback Alex Smith connecting on a 20-yard touchdown pass to tight end Anthony Fasano. The Broncos' offense subsequently marched down the field, but had to settle on a 24-yard field goal by Barth just before halftime. The Chiefs' defense forced a fumble off Manning deep in Broncos' territory on the Broncos' first possession of the second half, but had to settle on a 39-yard field goal by placekicker Cairo Santos. Barth added two more field goals a 30-yarder midway through the third quarter and a 33-yarder early in the fourth quarter to increase the Broncos' lead to 26-10. The first field goal came after a DeMarcus Ware interception of Smith on a deflected pass, while the second field goal came after Chiefs' cornerback Marcus Cooper muffed a punt. The Chiefs narrowed the Broncos' lead, with Smith throwing a 12-yard touchdown pass to running back Jamaal Charles. However, Broncos' safety T. J. Ward knocked away a two-point conversion pass from Smith intended for Fasano that would have brought the Chiefs to within a one-score deficit. Barth added one more field goal a 37-yarder midway through the fourth quarter. The Broncos' defense subdued the Chiefs for the remainder of the game. With the win, the Broncos swept the Chiefs for a third consecutive season. Peyton Manning improved his personal record to 11-1 all-time in games against the Chiefs.
