According to Fitzsimmons, students can, and a few likely do, purchase essays from various private sources. Electronic scanning sources cannot detect these works, since while they are not the students’ own, they are not technically unoriginal...
...containing colon cancer in people like Snow is the ability to detect recurrent tumors. Current imaging tests including MRI and PET scans may not pick up the small micrometastases that seed repeat growths; PET scans rely on the tumor's voracious appetite for glucose for energy, but until the tumor's activity reaches a certain threshold, it won't show up on the scan. So researchers are working on finding protein markers in the blood released by tumor cells that spread outside the colon; experts believe that cancer cells that venture outside the original tumor are equipped with special markers...
...attracting supporters - and driving the man. "I've always been sensitive to certain looks," he writes in his recent book. (Its title, Project of Hope, recalls the autobiographical musings of another mold-breaking presidential candidate on the other side of the Atlantic.) "I've always been able to detect condescension, that movement of the eyes that goes from top to bottom...
...treatment blocking Glut2 is not viable. It is standard medical knowledge that glucose transporter Glut2 moves glucose from blood to cells, allowing faster absorption, according to a press release from the Joslin Diabetes Center. After birth, Glut2 is concentrated in the pancreas and liver, which use Glut2 to detect high levels of glucose in the blood. At high concentrations of blood glucose, Glut2 increases the velocity with which glucose is taken into the cell. Loeken found that Glut2 is expressed unexpectedly early in the embryonic development of mice, exposing the embryo to the abnormal amount of glucose present...
Early cancer testing is always a good idea, but it might not be a lifesaver. A study published in the Journal of the American Medical Association finds that CT scans to detect lung cancers may not result in fewer deaths. Using statistical models, the authors calculated that when small lesions were diagnosed in patients, they ended up with the same mortality rate as those not screened. It turns out that the scans could pick up growths that do not progress into deadly cancer. However, another study, published last fall, found that screening shrinks death rates. The definitive trial...
