Wild birds help to create human flu vaccine

...spread of avian flu. Wild birds, some of which are critically threatened or endangered are also being impacted directly by the H5N1 strain of influenza virus. Focusing resources on the hubs and activities where humans, livestock, and wildlife come into close contact is the best hope for successfully preventing...

Many smokers fail to quit after cancer diagnosis

...has largely been focused on healthy smokers and is critically dependent on smoker motivation. The diagnosis of cancer, according to research, is a strong motivator for many smokers and thus, provides a window of opportunity to begin treatment for smoking addiction. Led by Ellen R.

Study provides insight into cellular defenses against genetic mutation

...post-doctoral associate Nao Hosoda, Ph.D. "That is critically significant because, knowing the structure and role of CBP80, we can now seek to develop drug-based gene therapies that interfere with it in cases where NMD contributes to disease-causing protein shortages." Researchers may be able to convert mRNA qu...

Enzyme affects hypertension by controlling salt levels in body

... sodium transporter," he said. "The sodium channel critically governs how much sodium gets reabsorbed." Normally, the kidney filters and reabsorbs about 99 percent of sodium from the blood and returns it to the body, excreting 1 percent through urine, said Dr. Huang, a nephrologist. However, if salt ingestion...

Computer modeling reveals hidden conversations within cells

Two designer drugs hit same lung cancer target, but only one is effective

...ce that mutations in the targets of designer drugs critically influence their effectiveness. Erbitux is an effective inhibitor of EGFR signals in colorectal cancer, which involves a normal, not mutant, EGFR molecule. "We now know of several groups of patients who benefit from therapy targeted at EGFR," says Pa...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...aid their findings mean that monkeys can provide a critically important animal model of how the brain controls what humans pay attention to in social situations. Such a model would enable scientists to better understand how processing of social attention works in the brain, and how it can go awry in such disor...
