Gambling monkeys give insight into neural machinery of risk

...ectrical activity of neurons in the region as they administered the same behavioral task to the monkeys. "We found that the neurons behaved very similarly to the monkeys," said Platt. "That is, as we increased the riskiness of a target, the neurons' activity would go up in the same way the monkey's frequency of ...

Elevated temperature enhances success of viral cancer therapy

Biota makes major antiviral discovery

...that Biota's new RSV antivirals are effective when administered orally. This should allow the product to be developed in a convenient oral formulation, such as a tablet or suspension. "The discovery of a novel, orally available RSV antiviral is a major achievement," said Dr Simon Tucker, Vice President of Resear...

Columbia scientists develop cancer terminator viruses

...the development of a "terminator" virus, which was administered to mice with pancreatic cancers at both primary and distant sites (akin to metastases). As predicted, when the virus was injected directly into the primary tumor, the virus destroyed not only the primary tumor, but also distant tumors. While the in...

New study shows SARS can infect brain tissue

...ith the disease. Immunosuppressive drugs should be administered carefully and on an individual basis, as they may allow amplification of the SARS coronavirus in the brain. "Superinfection" with other pathogens could also contribute to SARS' harmful effects on the brain. "Physicians should pay more attention to th...

Bacteria in Household Dust May Trigger Asthma Symptoms

.... Two research assistants visited each household, administered a detailed questionnaire, conducted a home inspection, and used a standardized protocol to collect samples. Dust samples were collected from bedroom, kitchen and living room floors, bedding, and upholstered furniture and assayed for endotoxin. A dise...

An essential regulator of body weight revealed

... Interestingly, the researchers found that if they administered the toxin when the animals were less than eight days old, while NPY/AgRP neurons were still developing and forming connections with neighboring cells, the mice ate normally and maintained a normal body weight. Their findings indicated that if NPY/AgR...

New antibody shows promise as cure for anthrax

...at the IgG protects test animals from anthrax when administered both before and after exposure to the disease. Since those findings, Dr. Robert Mabry of the Iverson and Georgiou laboratory has reformulated the antitoxin to make it last longer in the bloodstream. Dr. Mabry also produced the antibody in bacteria...

Past illegal blood donation in China linked to hepatitis C virus infection

...in Shanxi Province. Structured questionnaires were administered and blood samples tested for HCV antibodies. HCV rates were 8% in all participants, 28% in former plasma/blood donors, and about 3% in non-donors. Selling blood or plasma was the strongest independent predictor for HCV-positive findings. Receiving a ...
