There are a number of conditions in which CoQ tissue concentrations are altered with functional consequences. Oxidative stress generated by, for example, physical exercise increases tissue ubiquinone levels by increasing biosynthesis, as does administration of drugs like clofibrate. In contrast, aging is generally associated with decreases in tissue CoQ levels. For example, levels of CoQ10 in the skin are low in childhood, reach a maximum at around 20-30 years of age, and then decrease steadily with increasing age. Topically applied CoQ10 can penetrate into the living cell layers of the skin and attenuate both the depth of deep wrinkles characteristic of photoaging, as well as the turnover of epithelial cells. CoQ10 is also highly effective in protecting skin cells known as keratinocytes from oxidative DNA damage induced by ultraviolet light. Similar to what is observed in human skin, the concentration of CoQ in various mouse and rat tissues changes with age; the highest level occurs at about the age of 30 da

Older women using estrogen-alone hormone therapy could be at a slightly greater risk of developing dementia, including Alzheimer's disease (AD), than women who do not use any menopausal hormone therapy, according to a new report by scientists with the Women's Health Initiative Memory Study (WHIMS). The scientists also found that estrogen alone did not prevent cognitive decline in these older women. These findings from WHIMS appear in the June 23/30, 2004, Journal of the American Medical Association*.

Today, science has a better understanding of why fruits and vegetables should be part of a healthy eating plan. You probably enjoy them for their wonderful flavors and bright colors. But, fruits and vegetables are good for you too. An eating pattern packed with plenty of fruits and vegetables includes two to three servings of fruits and three to five servings of vegetables each day.

Working with pigeons who were fed a diet of rice hulls, Funk was able to show the existence of a substance, later known as thiamine, which could cure beriberi. Because this compound was an amine, Funk coined the term "vitamine" to describe a set of amines essential for life. When further research showed that not all vitamins were amines, the term was shortened to vitamin..
