Bullying among sixth graders a daily occurrence, UCLA study finds
...and co-author of the study. "We knew a small group gets picked on regularly, but we were surprised how many kids reported at least one incident. We didn't know how much bullying we would find over a few random days." Bullying includes name-calling, making fun of others, spreading nasty rumors and physical...Some brain cells 'change channels' to fine-tune the message
...the cells' AMPA receptors, and so too much calcium gets inside. If these threatened nerve cells can swap their calcium-allowing channels for the kind that keeps calcium out, it might be possible to harness that switch to prevent the cells from dying. "But that's a big 'if' at this point," says Huganir....Mechanism of RNA recoding: New twists in brain protein production
...lowed to the letter. Sometimes, the genetic recipe gets edited after cells copy DNA to RNA--a close chemical relative--during transcription. Think of DNA as an unalterable "read only" copy of the genetic code and the RNA as a "writable" working copy that cells can edit extensively--adding, deleting, and m...Epstein-Barr virus protein crucial to its role in blood cancers

"It makes sense that when hormone therapy gets rid of cancer cells and the protein antigens they carry, it's easier to re-educate the immune system to fight cancer cells when they come back in smaller numbers."

Not surprisingly, one of the most important risk factors for severe infection was exposure to cigarette smoke. "Smoking in the household is re...Gender a factor in who gets bypass surgery

In 1988, twelve percent of female patients who had profiles consistent with the bypass surgery received it-- as compared to twenty-four percent of men. In 1998, among similar types of patients, twenty percent of females received hea...Concerns over the future of children's health care in British general practice

...isease," he says. "We think as the diabetic kidney gets damaged, more and more of these proteins and free fatty acids go through the urine and hit these tubular cells. The tubular cells, via CD36, take them up and start the apoptosis pathway and ultimately cause fibrosis and progressive kidney failure as ...Computer model being developed at Stanford may help surgeons better predict patient outcomes

In large-animal studies, he said, they can predict flow after an aortic graft within 10 percent.
