• Resveratrol extends the lifespan of human cells

    Mar 14, 2005
    A family of enzymes known as the Sir2 family or sirtuins are important for many cellular processes including lifespan extension. Resveratrol has recently been shown to activate Sir2 enzymes in both laboratory and animal studies. Resveratrol has also shown ability to extend the lifespan of model organisms.
  • Natural Lycopene and Beta-Carotene decrease the risk of pancreatic cancer

    Mar 08, 2005
    Fruits and vegetables help decrease the risk of pancreatic cancer. This study was performed to see if it is the carotenoid content of the fruits and vegetables that protects the pancreas. A case-controlled study of 462 patients with pancreatic cancer was compared to 4721 cancer free adults in 8 Canadian Provinces.
  • Folic Acid and Vitamin B12 cut hip fracture risk after a stroke

    Mar 07, 2005
    The risk of breaking a hip is much higher in stroke sufferers than in other people their age with an increased risk of 2 to 4 times. The connection between stroke and hip fracture is thought to be elevated homocysteine. Elevated homocysteine increases the risk of ischemic stroke (the most common form of stroke) and hip fractures in elderly men and women.
  • NADH may protect the brain in Alzheimer's disease

    Mar 04, 2005
    NADH is a coenzyme (Coenzyme 1) that plays a key role in cellular energy production, energy in the brain, and dopamine production. In previous trials NADH has been shown to improve cognitive function in patients with depression, Parkinson's disease, and Alzheimer's disease. This study was designed to test the effects of NADH on Cognitive functioning in patients with Alzheimer's disease.

    b>Zinc Deficiency Causes Spontaneous Cell Death in Mice Studies involving zinc deficiency have highlighted how various nutritional deficiencies can trigger a programmed death of otherwise healthy cells, an incident that is only supposed to occur in senescent, diseased, or abnormal cells. In mice, zinc deficiency caused a 300% increase in the death and destruction of pre T-cells (future infection fighting immune cells). This destruction of the T cells lead to the shrinking of the thymus gland (this is an event that usually occurs with aging) and decreased immune protection.
