Albatross study shows regional differences in ocean contamination

... "It is very difficult to show a cause-and-effect link in a wild population, but there is evidence of health impacts in other species at these contaminant levels," Finkelstein said. Humans are exposed to the same contaminants when they eat seafood, she added. "It is important to realize that these co...

Atmospheric ozone recovering in mid-latitudes, report shows

...mile (11- to 18-kilometer) region, the researchers link a slight increase in ozone to changes in atmospheric transport - perhaps caused by natural variability or human-induced climate warming - rather than atmospheric chemistry. The changes in this altitude range - below the region where ozone-depleting g...

Antarctic Treaty Meeting moves to protect frozen continent from non-native species

...arts of the world has shown that there is a direct link between numbers of people visiting a remote area and the numbers of non-native species that survive. Once established, they can be very difficult to eradicate. Prevention is better than cure." Concerned that a rapidly changing and warming climate on...

UAB researchers confirm HIV-1 originated in wild chimpanzees

...Birmingham (UAB), has discovered a crucial missing link in the search for the origin of HIV-1, the virus responsible for human AIDS. That missing link is the natural reservoir of the virus, which the team has found in wild-living chimpanzees in southe...

Cycles of cell death, proliferation key to liver cancer

...s a key role in liver cancer in mouse models. One link between inflammation and cancer is known to involve the NF-kB pathway, which regulates gene expression. In research published in the journal Cell in 2005, Karin and his colleagues at UCSD implicated the pathway's activator, IKK , in chemically induc...

Matrilin-3 gene discovered to prevent onset of osteoarthritis

...ther tissues throughout the body. There has been a link between mutated forms of matrilin-3 and hand osteo... matrilin-1 and -3 in mice in order to study their link to osteoarthritis. When matrilin-1 was knocked out, there was no apparent effect. When matrilin-3 wa...

Selenium-protein deficiency raises prostate cancer risk

...e researchers suspected, it did. "It's a hardcore link in an animal model system of selenium-containing proteins to prostate cancer and, by extrapolation, the mechanism by which selenium prevents cancer," said Diamond. Further research is underway to corroborate the stimulating effect of dietary seleniu...

Ever-happy mice may hold key to new treatment of depression

Our data also provide evidence of a link between these PDGFRá B cells and the early changes associated with tumor initiation, suggesting they may be targets of neoplastic transformation. The regression of atypical hyperplasia after PDGF removal described here suggests that inhibition of PDG...
