Medications that lower blood pressure linked to reduced risk of Alzheimer's disease

...t low potassium concentrations are associated with oxidative stress, inflammation, platelet aggregation and vasoconstriction, all of which are possible contributors to AD pathogenesis." "We suggest these findings should prompt further epidemiologic and basic science studies into the possible neuroprotective ef...

UCI researchers to study health effects of exercise in children

...ird will explore the impact of exercise-associated oxidative stress in obese children. All three will help determine how these exercise-activated molecular mechanisms are altered by gender, physical-maturity levels and the common pediatric conditions of asthma and obesity. These mechanisms are of particular i...
