Instead of examining one gene at a time researchers can now look at tens of thousands of genes simultaneously. The microarray (a new research tool that combines molecular biology and computers) allows researchers to take samples of tissues and process them in such a way as to isolate the specific molecules between deoxyribonucleic acid (DNA), the molecules that carry all the genetic information necessary for the organization and functioning of most living cells, and mRNA (ribonucleic acid), the messenger protein peptides, which translates the information encoded in our DNA.

Of all the carotenoids, lycopene has been shown to exhibit the highest physical quenching rate of singlet oxygen. Lycopene has very high antioxidative activity and exerts a protective effect from various diseases, including cataracts, aging of retinal pigment epithelial cells, prostate cancer and lower urinary tract symptoms in older men.

An important new study published in the July issue of the American Journal of Epidemiology suggests that smokers who consume a wide variety of dietary antioxidants, including reasonable amounts of beta carotene, have a substantially lower risk of developing lung cancer. Scientists from a number of universities, including Yale, together with resea...

There is a difference between nutraceutical formulations designed by scientists around good medicine and those designed by marketeers around media focus (heat). There are a number of important questions doctors and consumers need to ask themselves before recommending or purchasing disease-specific nutraceutical formulations.

Paul Harvey is so good that large numbers of sponsors are lined up waiting for the chance to have him endorse their products because he has the delightful ability to make us suspend disbelief - if only in admiration for the magical way he woos us to spend our money on liver pills, utensils that dice, slice and chop and now vitamins to prevent or slow the progression of age related macular degeneration.

Have you ever zigged when you should have zagged, gone up the down staircase, slept when you should have been wide awake? Recent science suggests that disruption of our internal circadian clock can cause affective disorders that frequently make us feel like we are marching to a different drummer. Three specific vitamins particularly affect our circadian clocks.

Last week the associated press (AP) reported on a cancer/antioxidant review featured on the cover of the most recent Lancet. The AP reported that a group of researchers from Denmark concluded "Antioxidant pills, except selenium, are useless for prevention of gastrointestinal cancers and may even be dangerous to your health." This news was reported despite the knowledge that many of the peer-reviewers of the paper emphatically concluded "There was no convincing proof of hazard."

Chronic inflammation is strongly linked to retinal degeneration, dry eye syndrome, cardiovascular disease, many cancers, and Alzheimer's. The chemical properties in Turmeric act as powerful anti-inflammatories, antioxidants, anti-angiogenics, and surgical wound healing accelerators.

At this point over a dozen carotenoids have been found in blood, but only two specific zanthophyll carotenoids (lutein and zeaxanthin) are found in the center of the retina (fovea). The fovea accumulates these two dietary xanthophylls, which constitute the macular pigment or macula lutea.
