Elevated inflammatory enzyme, Lp-PLA2, significantly linked to ischemic stroke

... levels of Lp-PLA2 had a statistically significant doubling of risk of suffering an ischemic stroke over a period of about six years compared to those with the lowest levels of the enzyme after taking age, gender and race into consideration (p <0.001).

... of the infection in an individual and the initial doubling time of the epidemic, with more detailed structure added by allocating cases to risk groups. The model's use in the design of strategies to minimize the risks of SARS in a previously unexposed community is demonstrated. Contact: Dr Mick Roberts, Inst...

Scientists generate human islet precursor cells in culture

... hIPCs showed substantial proliferative potential, doubling in number about every 60 hours, and by 90 days had expanded by almost a billion fold. Not stem cells, these precursor cells are transitional cells since they originated from insulin-producing islets. The authors note, however, that this finding doe...

'Lighter than air' breathing more than doubles COPD patients' exercise endurance

... In the current study, the more than doubling in the time COPD patients could exercise "was associated with a significant reduction in lung dynamic hyperinflation (DH) at isotime (Iso; when the patients stopped exercising during regular air breathing), as reflected by the increase in inspiratory...

'Jumping gene' helps explain immune system's abilities

...eftover DNA also forms a hairpin loop, temporarily doubling back on itself, postdoctoral fellows Liqin Zhou, Ph.D., and Rupak Mitra, Ph.D., discovered in experiments in test tubes and with E. coli bacteria. Although this loop distances Hermes from its well-studied cousins, the Hermes protein still has an impo...

FDA approves ABRAXANE(TM) for metastatic breast cancer

...monstrated a superior response rate with an almost doubling of the reconciled target lesion response rate when compared with the solvent-based Taxol in a prospectively randomized trial of 460 patients with metastatic breast cancer. Because it contains no toxic solvents, this next-generation taxane product en...

NJIT astrophysicist who revived earthshine named fellow of American Physical Society

...toring Earth's climate. The NJIT team is more than doubling the size of the BBSO telescope. The current 65-cm (2 foot) vacuum aperture telescope will be replaced by a modern off-axis, open air, 1.6-meter (5 foot, 3 inch) clear aperture instrument. The National Science Foundation (NSF) recently awarded the pr...

When does a mole become a melanoma?

...ce is rising faster than that of any other cancer, doubling every 10-20 years. When melanoma is metastatic, or spreads to other organs, the average life expectancy is only 6-10 months. Previous studies have indicated that the BRAF gene is mutated in about 75 percent of melanomas, but until this study, no on...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice
