Ocean virus identified in human blood samples

...normal blood donors that had been determined to be safe and were used in blood transfusions, 12 percent showed antibody to Vesivirus, suggesting a previous infection. In donors who had evidence of liver damage based upon a liver enzyme test, and whose blood had been discarded as a result, 21 percent had...

For one Stanford doctor, the beat goes on during open-heart surgery

.... It found that the beating-heart technique is as safe as conventional heart surgery, with fewer complications and lower costs. The consensus report, based on randomized controlled trials and retrospective studies, concluded that when complications such as blood loss, stroke, kidney failure and irregular...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...m chimpanzees and humans may provide a potentially safe and effective way to treat the serious complications that can occur following smallpox vaccination--and possibly may even protect against the deadly disease itself. The study, led by researchers with the National Institute of Allergy and Infectious D...

Thin tough skin, slow-growing gills protect larval Antarctic fish

... surface ice, when they hatched, seeking perhaps a safe area to hide from predators, Cziko said. The average freezing point of the larval fish fluids was about -1.3 degrees Celsius, according to testing with a nanoliter osmometer. Yet the fish hatch into water at almost -2 degrees Celsius. "With all thi...

It's in the genes: Study opens door to new treatment of the blues

... available treatments for depression are generally safe and effective, they are still not ideal. It takes long-term treatment before seeing clinical benefit, and potential side effects are a serious problem. The findings of this study provide exciting new leads and point to potential strategies, such as d...

The pneumococcal vaccines have been shown to be safe and very effective at preventing widespread infections and are expected to greatly reduce serious pneumococcal disease in UK children, as they already have done in the USA. Current research, such as the capsule study described here, is intended to e...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

... "This virus is kind of a gift from nature, a very safe and efficient virus, but nature never evolved it to be a human therapeutic. So, in a sense, we have to re-evolve it for that purpose," he said. ...
