...rget the PDGF receptor must therefore be used with caution for the treatment of tumors in which the PDGF receptor is not the target on the tumor cell itself.

...olic acid fortification, Mason and colleagues urge caution and debate. We must examine the effects of folic acid fortification on the population as a whole, which includes better defining the nature of the relationship between folic acid fortification and colorectal cancer, says Mason. Improved monitoring an...Bright future for nano-sized light source
... and cellular signal pathways. Yang and Liphardt caution that the nanowire light source technology is at a very early stage of development. Liphardt compares it to where atomic force microscopy was some 10 years ago. He also says that this technology is not intended to replace existing microscopy technolog...Human genetic 'deserts' are teeming with significant life
... these pathologies. They also suggest that extra caution should be used when associating a genetic phenotype with a gene knock-out or knock-in, where genes are added or deleted from a model organism in order to study the effect of therapies, he says.

...njuries, and not to throat cancer; therefore, they caution that further studies are needed in larger groups of patients to confirm if this could be a useful tool to monitor for cancer, infection, or other complications. In addition, because IL-6, IL-8, VEGF, and HGF have been detected in the blood of patient...Gene mutation linked to increased athletic performance in whippets

...irector, U-M cardiac surgeon Steven Bolling, M.D., caution that their results cannot be directly translated into humans. But they are encouraged by the positive signs seen in the new data. "Rats fed tart cherries as 1 percent of their total diet had reduced markers of metabolic syndrome," says Seymour. "P...Researchers identify new genetic risk factors for type 2 diabetes
...ctions of disease risk need to be interpreted with caution because the diabetes group in their sample was "enriched" with people who had affected siblings and because the healthy group excluded people who had impaired glucose tolerance or impaired fasting glucose. ...IMS reaction to report on breast cancer incidence in 2003 in US
... the International Menopause Society (IMS) advises caution in linking these two parallel trends observed in the US. Any attempt to put both observations into one framework is premature and there is little scientific basis for such an assumption. In fact, the authors themselves mention in the manuscript that ...Cancer tip -- Nanoparticles can damage DNA, increase cancer risk
...eantime, the experimental team suggests that great caution should be taken in handling such nanoparticle suspensions and that any uncontrolled release should be avoided. "Until we understand which types of nanoparticles are harmless and which have the potential to be harmful, I think it is prudent to lim...Glucose triggers brain cell death in rats after hypoglycemic coma

Insulin is an essential hormone that moves glucose from the bloodstream to individual cells, where it is broken down and used for energy. Diabetics do not produce enough of their own in...Switching genes to overdrive improves muscular dystrophy symptoms in mice

I think that if we could elevate the levels of PGC-1alpha in the muscles of patients with Duchenne muscular dystrophy, it is likely that we could slow or reduce...Biologists call for better choice of model organisms in 'evo-devo'
