Williams's group collected 16,000 DNA samples from Alzheimer's patients and healthy controls, while the French team, led by Dr. Philippe Amouyel at the Pasteur Institute, gathered more than 7,000 similar samples. Each team worked independently, unaware of the other lab's research, until both happened to present their data at the International Conference on Alzheimer's Disease in Vienna in July. Williams, who was in the audience when Amouyel gave his talk, immediately checked her database on her laptop and found to her delight that her group had identified the same high-risk genes as Amouyel...
When it comes to weight gain, the timing of your meals may be just as important as what or how much you eat. According to a study of lab animals published online by the journal Obesity, eating during the hours that the body would naturally be sleeping may lead to excess weight gain...
...while these hormones have been successfully manipulated in lab mice to prompt weight gain or loss, the same has not been true in humans. Experiments in which obese human patients were injected with leptin have failed, because the metabolic pathways that control hunger and fullness in people are far more complex than they are in mice. Knocking out one of, say, 50 such pathways through drug treatment just means the other 49 will eventually pick up the slack, says Dr. George Fielding, a bariatric surgeon at the NYU Program for Surgical Weight Loss...
Although the new findings in Obesity cannot yet be applied outside the lab, other research supports the idea that the disruption of sleep (that includes standing in front of the fridge eating chicken at 2 a.m.) may have something to do with weight gain in humans. Studies of night-shift workers like nurses and factory workers indicate they are at higher risk for being overweight than their daylight counterparts, partly due to poor sleep routines and partly because of their tendency to eat heavy meals late at night, says Aronne. Other studies show that people who get a full eight...
...result of the insurance policy changes, all students will now pay $1126 in student health fees for the year—down $300 from last year. The cost of the supplemental plan has increased from $1404 to $1714 this year in order to absorb the additional pharmacy and lab testing benefits...
