Diabetics susceptible to compromised cardiovascular function from high levels of air pollution
.... Specifically, on days when sulfate pollution was elevated
the researchers found an 11 percent decrease in vascular reactivity among diabetic participants. On days when black carbon concentrations were elevated, diabetic study participants had a 13 percent decrease in vascular reactivity. In comparison, non-...
Study establishes new class of cancer-causing genes
...at idea directly, the researchers examined whether elevated
expression of mir-17-92 or other microRNAs could accelerate the onset of cancer and/or decrease survival in a mouse model of B-cell lymphoma. As expected, control animals developed B-cell lymphoma after about 2 months, and the overall survival of thi...

Engineered skin offers clues to melanoma development
...a. The scientists also investigated the role of elevated
telomerase activity. In combination with other cancer genes, hTERT, the active protein in the enzyme telomerase, caused progressively invasive melanoma. In contrast, melanocytes that did not receive hTERT remained in an early stage of benign growth. ...

Aerobic exercise helps find genetic regions linked to prediabetes
...logia. Prediabetes is characterized by the body's elevated
resistance to insulin, the hormone that regulates blood glucose levels and energy storage. The condition generally advances to type 2 diabetes as the pancreas works to secrete insulin to compensate for increased insulin resistance in the body's liver...
