...said Kenneth R. Chien ’73, the senior author of the paper and the director of the Cardiovascular Research Center at MGH, a Harvard Medical School teaching hospital. Current therapies for recovering damaged heart tissue due to disorders such as heart attacks involve injection of bone marrow or blood cells and are largely ineffective, experts say. However, the findings of the MGH and Children’s Hospital studies could move scientists closer to being able to regenerate damaged heart tissues using stem cell therapies. Deepak Srivastava, the director of the Gladstone Institute of Cardiovascular Disease...
Most women know that osteoporosis, or thinning of the bones, is a big risk after menopause. Probably most don't know that drinking cola increases the risk. A study in the American Journal of Clinical Nutrition looked at 1,125 men and 1,413 women ages 29 to 86. Among the women--but not the men--there was significant loss of bone density in cola drinkers, whether they drank diet or regular. It's not the first evidence, but it's the strongest to date linking cola to bone loss...
...Harvard Bone Marrow Initiative (HBMI) will hold donor registration in the undergraduate Houses for the first time tomorrow. The initiative, founded this school year, designated this month its Bone Marrow Destination Month and will attempt to recruit bone marrow donors from across the University. The initiative focuses particularly on people from ethnic minorities since minority patients are less likely to find a match, according to HBMI co-chair Julie Goswami ’08. The effort involves the Harvard Cancer Society, Harvard South Asian Association, Harvard Asian American Association, Asian American Brotherhood, Black Students’ Association, and Fuerza Latina...
...regret only that he cut the film to the bone; 96 mins. is a fine length for Scary Movie 4 but insufficient for all the ideas, images and feelings Aronofsky wanted to cram into The Fountain. If you ask any director what the favorite cut of his latest movie is, he?ll say the four-hour assembly - and that trimming the film to manageable length is like hacking off so many limbs. (Presumably that?s why Peter Jackson has added 51 mins. of footage for the DVD of King Kong, which in theaters clocked in at an elephantine 3hr.7min...
...stem cell field in recent years, embryos aren't the only source of these versatile mother-cells. Political leanings aside, researchers are beginning to appreciate that many tissues in the body have their own stem cells. Blood cells, for example, derive from a single hematopoietic stem cell in the bone marrow, and now two groups of scientists from Boston report that they have identified a similar mother stem cell from which most heart cells arise. Working with mice, one group at Massachusetts General Hospital isolated a cardiac stem cell that generates the three major cell types of the mammalian heart...
