...surprising trial, researchers led by Dr. Teresa Liu-Ambrose at the University of British Columbia randomly assigned 155 aging women to three separate groups and directly compared the cognitive effects of two types of exercise: resistance training, done once or twice weekly, in which participants worked out with free weights and weight machines and did squats and lunges, versus toning and balance exercises, which participants did twice a week. (See pictures of a canine cognition...
That was the same message of the final exercise paper in the journal, by researchers at University of Erlangen-Nuremberg in Germany. In this trial, a group of 246 elderly women were randomly assigned to an 18-month exercise regimen or wellness program. The women participating in the four-times-weekly exercise sessions, which involved aerobics and balance and muscle training, improved their bone mineral density by nearly 2%. The women in the wellness group, which focused on walking, muscle relaxation and breathing skills, had a 0.33% increase in bone density over the same time period. Perhaps more important, participants...
Despite the positive evidence, however, not all researchers are ready to suggest that exercise is a sure-fire prescription against mental decline or chronic disease in healthy people. To make that claim, a large, longer-term, controlled trial would be needed, in which participants are randomly assigned to exercise or not, and are then followed for the development of chronic conditions such as cancer, heart disease or dementia...
...flew to Houston, where he was given a briefing on a new agent called ibalizumab, an antibody that appeared able to block HIV's entry into healthy cells. In the 200 or so HIV-positive patients tested in the early trial, the compound was effective, but Tanox was worried about resistance. No matter how promising ARV drugs were, HIV inevitably found a way to evade them. So while the agent seemed to reduce the burden of virus in the blood up to 90% in patients with full-blown AIDS, no one knew how long the viral standoff would last...
...case--concerning the voter-approved 2008 referendum known as Proposition 8--is already setting some unusual precedents. The plaintiffs are represented by Theodore Olson and David Boies, the star litigators best known for arguing on opposing sides in the Supreme Court case that decided the 2000 presidential election. The trial could also be one of the first federal proceedings broadcast on YouTube. Judge Vaughn Walker's decision to allow video cameras in the courtroom was overruled by the Supreme Court to protect witnesses from harassment, but the order expired Jan. 13, leaving open the possibility of later coverage...
