New studies suggest airborne SARS transmission is possible

... an infected patient's hospital room. The authors cautioned that their results do not document any cases of airborne transmission of the SARS virus from one person to another, only the dissemination of the virus from an infected patient to the air, via breathing or coughing. During the outbreak in Toronto ho...

Gene therapy advance treats hemophilia in mouse models

...r hemophilia but are not yet applicable to people, cautioned Paul McCray, UI professor of pediatrics and the study's corresponding author. "It's an exciting finding, but we are still many steps away from a possible gene therapy for people with hemophilia," he said. Hemophilia A is the leading sex-linked bleed...

Grabbing addiction by the tail

.... Although the initial studies are promising, Wang cautioned that the drug is in the early stages of development and is years away from testing in humans. During addiction to drugs, cells in the nucleus accumbens ?a tiny ball of tissue deep in the brain involved in pleasure and motivation ?mis-communicate. No...

Regenerating worms help elucidate stem cell biology

...ting the progeny of adult stem cells in humans. He cautioned that more work is needed to determine just how functionally similar the factors regulating stem cells in planaria are to those in higher organisms. But so far there's good evidence that many of the important genes are the same, he said. And the curre...

Engineered mouse mimics cognitive aspects of schizophrenia

...olong life, you would induce diabetes right away," cautioned graduate student and first author Suzanne Wolff. When this pathway had been clipped in worms, they lived longer than normal, but their larval development and reproduction were disrupted. "So, the central question became whether we would be able to g...

Inflammation and drugs to control this activity studied in a variety of tumors sites

... of Texas M. D. Anderson Cancer Center in Houston, cautioned that they are not implying that use of antihistamines causes brain tumors, but rather that these medications may be part of a complex milieu of factors that contribute to their development.

...ome contamination of the samples," he said. Ganem cautioned that any link between XMRV and prostate cancer is tenuous at best. "First, the genetic variant we studied occurs in familial clusters that constitute only a very small sliver of prostate cancers," he said. "And secondly, there are many reasons to bel...

Parkinson's disease mechanism discovered

...in or to treat symptoms of the disease. Lindquist cautioned that the findings "have not by any means proven that this mechanism of pathology or the compounds that affect it are relevant to humans. However, given the fact that we've found the same results in yeast, flies, worms and rat neurons, I would be very...

How IVF could be causing genetic errors in embryos

NYU researchers decorate virus particles, showing potential to enhance MRI capabilities

...etween different tissue types." While Kirshenbaum cautioned that many obstacles remain in using this process to enhance MRI for clinical applications, he said the results point to the potential of enhancing specific MRI capabilities. "If a radiologist wants to design a versatile probe that can be used ...

A sweet solution for Alzheimer's disease?

...h scholar and senior author Peter St George-Hyslop cautioned that the chemicals tested in these studies are not the type of inositol sold commercially as a nutritional supplement. That type--myo-inositol--has been shown previously to be ineffective at breaking up amyloid aggregates, he said. In the brain of a...

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...sk for BPH found in the veterans groups, Dr. Gupta cautioned that the finding should not be interpreted as a positive result. "It may be construed that a decrease in the risk of BPH is not a harmful effect, but the larger picture is that dioxins are affecting the normal growth and development of the reprodu...

Computer scientists unravel 'language of surgery'

...rofessor at the Oregon Graduate Institute. Hager cautioned that the project is not intended to produce a "Big Brother" system that would critique a surgeon's every move. "We're trying to find ways to help them become better at what they do," he said. "It's not a new idea. In sports and dance, people are stud...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows
