Researchers uncover association between free radical-mediated reactions and progression of SLE

University of Texas Medical Branch researchers have uncovered an association between free radical-mediated reactions and the severity and progression of system lupus erythematosus. Higher levels of oxidative and nitrosative stress markers were found in SLE patients with greater disease activity suggesting a causal relationship. Full findings of the study are available in the July issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

University of Montreal scientists discover free radical mechanism to viral invasion

Canadian researchers have discovered a new way the body combats respiratory viral infections. In the prestigious journal PLoS Pathogens, scientists from the University of Montreal and the University of Montreal Hospital Research Center explain how the NOX2 molecule, an enzyme that generates a burst of highly reactive oxygen derivatives (or free radicals), activates defense genes and molecules when viruses invade lung cells.

Anti-aging supplements may prevent decline in physical function: Researchers

Anti-aging supplements made up of mixtures might be better than single compounds at preventing decline in physical function, according to researchers at the University of Florida's Institute on Aging. In addition, it appears that such so-called neutraceuticals should be taken before very old age for benefits such as improvement in physical function.

Cell Therapeutics reports cardiac safety results from phase II trial of pixantrone in CHOP-R regimen

Cell Therapeutics, Inc. reported today preliminary cardiac safety results from a North American randomized phase II trial which substituted pixantrone for doxorubicin in the standard CHOP-R regimen. Called PIX203, the randomized trial compared CPOP-R directly to CHOP-R in the 1st line treatment of high risk patients with diffuse large B cell non-Hodgkin's lymphoma (DLBCL, NHL).

Mild-mannered organelles can detect virus invasion signals: Researchers

Within cells, an ancient antiviral duo can deliver a one-two knockout to thwart invading viruses, report researchers who have just unmasked the cellular sidekick that throws the first punch. The findings mean scientists must rethink the design of antiviral immunity and how the body fends off viruses of all types, including influenza and HIV.

Chokeberry extract reduces weight gain in insulin-resistant animals

Chokeberry bushes have for centuries been residents of eastern deciduous forests where their bright red and dark purple fruits continue to be favorite snacks of local bird species. Native Americans have also traditionally eaten dried chokeberries and prepared teas from parts of the plant, and several domesticated varieties now grace contemporary lawns and gardens from coast to coast.

Inflammation has a role to play in premature births and brain injury: Sahlgrenska Academy thesis

Researchers have gone some way to explaining what happens during premature births and how brain injury develops in premature babies. New findings show that inflammation in both the amniotic fluid and the baby's brain has a role to play, reveals a thesis from the Sahlgrenska Academy.

Drinking orange juice with fast-food meal may help prevent vascular inflammation

Eating foods containing flavonoids -- orange juice, in this case -- along with a high-fat, high-carbohydrate fast-food meal neutralizes the oxidative and inflammatory stress generated by the unhealthy food and helps prevent blood vessel damage, a new study by University at Buffalo endocrinologists shows.
