...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 that could be detected, hopefully with something as simple as a blood test...
Jacobs-Lorena and his colleagues at Johns Hopkins University have taken a different approach to combating malaria. They have engineered a mosquito that produces an extra protein in its gut, which blocks the malarial parasite from infecting it. The team recently discovered unexpectedly that one of their engineered mosquito strains is “fitter” than ordinary mosquitoes. Once you infect it with a certain strain of mouse-borne malaria parasite, it lives longer and produces more offspring than infected wild-type mosquitoes. Place equal numbers of the two types of mosquitoes into the same cage...
Carb-counting? Fat-free? Not eating past seven pm? Not these men. These are the men who have protein shakes—before they start eating. These are the men who stay up late, waiting for the pizza delivery guy with the two large pizzas. These are the men who look like they could rip a phonebook in half and then eat it for a snack. These men are Harvard’s linemen. And for them, with the simple goal of protecting the quarterback or opening holes for the running back comes another objective: being big. Real big.A typical...
...People have been drinking raw milk for a long time, of course - at least since sheep and goats were domesticated in the 8th or 9th century B.C. Raw milk is rich in protein and fat, and milk from cows became a staple of the American diet in colonial times. When milk leaves the animal, however, it can also contain any number of pathogens, which is why most doctors consider pasteurization - subjecting milk to a short burst of heat followed by rapid cooling - one of the great public-health success stories of the 20th century. By eliminating most of the pathogens...
...protein that is helpful to embryo survival may actually be harmful to babies born to diabetic women, according to a recent study released by a Harvard Medical School (HMS) affiliate. Past research has found that diabetic women are two to five times more likely than women with normal blood sugar levels to have babies with birth defects. In the recent study, which was conducted on mice, HMS associate professor Mary R. Loeken and her colleagues at the Joslin Diabetes Center identified the expression of the glucose transporter Glut2 early in embryonic development as a factor in this disparity. However, because...
