Important privacy considerations when shopping for car audioThe Internet is fast becoming the dominant medium for business and communication, but it still resembles something of a frontier, because there is little regulation. If you are looking for car audio then you are doing so in an unregulated marketplace. Most efforts have relied on the Internet industry to police itself. Although there has been some notable success with self-policing, continued abuses have increased calls for government intervention. That's where our role in pre-checking car audio sites comes in. Our car audio provider is solid and reliable. Some aspects of the Internet could undoubtedly use some regulation, but this task is not as simple as it may seem. The very nature of the Internet makes it difficult, if not impossible to regulate. However in the midst of this many car audio retailers survive and prosper. At the same time, the absence of regulations means that everyone who uses this essentially public network can be a target for anyone who has the technical know-how and the will to invade their privacy. Privacy was foremost in our minds when sourcing the right car audio retailer for you. Their link appears below. While the threat from hackers is low for individuals, a more serious threat to personal privacy comes from unscrupulous car audio companies that operate websites for quick quids. Many car audio sites require you to register before you can use its services. Often you must provide personal information, such as your name, street address, and e-mail address. Then as you browse the site, data is collected as to which pages you visited, how long you remained on each page, the links you clicked, what terms you searched, and so on. After a number of visits to the site, a personal profile emerges. The question is, what do car audio site operators do with this information? Most claim that they use it to personalize your experience on the site. For instance, if a car audio site learns that you are interested in car audio, the next time you visit the site, you might be presented with an article or advertisements for that and related products. But some car audio websites sell this information to marketers, which means that you may find yourself receiving unwanted catalogs from garden suppliers. Our preferred retailer does not do this. We feel so confident that your car audio shopping experience will be a good one that we have built this site so that you can go straight to the prime car audio retailer without wasting a lot of time checking out vast numbers of very ordinary providers. oxidant Vitamins and Zinc Reduce Risk of Vision Loss from Age-Related Macular Degeneration by: ARA Content
(ARA) - Findings from a nationwide clinical trial reported that high levels of antioxidants and zinc significantly reduce the risk of advanced age-related macular degeneration (AMD) and its associated vision loss. Scientists found that people at high risk of developing advanced stages of AMD, a leading cause of vision loss, lowered their risk by about 25 percent when treated with a high-dose combination of vitamin C, vitamin E, beta-carotene and zinc. In the same high risk group -- which includes people with intermediate AMD, or advanced AMD in one eye but not the other eye -- the nutrients reduced the risk of vision loss caused by advanced AMD by about 19 percent. For those study participants who had either no AMD or early AMD, the nutrients did not provide an apparent benefit. The clinical trial -- called the Age-Related Eye Disease Study (AREDS) -- was sponsored by the National Eye Institute (NEI), one of the Federal government's National Institutes of Health. "This is an exciting discovery because, for people at high risk for developing advanced AMD, these nutrients are the first effective treatment to slow the progression of the disease," said Paul A. Sieving, M.D., Ph.D., director of the NEI. "AMD is a leading cause of visual impairment and blindness in Americans 65 years of age and older. Currently, treatment for advanced AMD is quite limited. These nutrients will delay the progression to advanced AMD in people who are at high risk -- those with intermediate AMD in one or both eyes, or those with advanced AMD in one eye already. "The nutrients are not a cure for AMD, nor will they restore vision already lost from the disease," Dr. Sieving said. "But they will play a key role in helping people at high risk for developing advanced AMD keep their vision." A common feature of AMD is the presence of drusen, yellow deposits under the retina. Often found in people over age 60, drusen can be seen by an eye care professional during an eye exam in which the pupils are dilated. Drusen by themselves do not usually cause vision loss, but an increase in their size or number increases a person's risk of developing advanced AMD, which can cause serious vision loss. Advanced AMD can cause serious vision loss. Scientists are unsure about how or why an increase in the size or number of drusen can sometimes lead to advanced AMD, which affects the sharp, central vision required for the "straight ahead" activities, such as reading, driving and recognizing faces of friends. "Previous studies have suggested that people who have diets rich in green, leafy vegetables have a lower risk of developing AMD," said Frederick Ferris, M.D., director of clinical research at the NEI and chairman of the AREDS. "However, the high levels of nutrients that were evaluated in the AREDS are very difficult to achieve from diet alone. "Almost two-thirds of AREDS participants chose to take a daily multivitamin in addition to their assigned study treatment," Dr. Ferris said. "The study also showed that, even with a daily multivitamin, people at high risk for developing advanced AMD can lower the risk of vision loss by adding a formulation with the same high levels of antioxidants and zinc used in the study." Dr. Ferris said some people with intermediate AMD may not wish to take large doses of antioxidant vitamins or zinc medical reasons. "For example, beta-carotene has been shown to increase the risk of lung cancer among smokers," he said. "These people may want to discuss with their primary care doctor the best combination of nutrients for them. With the use of the high levels of zinc, it is important to add appropriate amounts of copper to the diet to prevent copper deficiency." The AREDS participants reported few side effects from the treatments. About 7.5 percent of participants assigned to the zinc treatments -- compared with five percent who did not have zinc in their assigned treatment -- had urinary tract problems that required hospitalization. Participants in the two groups that took zinc also reported anemia at a slightly higher rate; however, testing of all patients for this disorder showed no difference among treatment groups. Yellowing of the skin, a well-known side effect of large doses of beta-carotene, was reported slightly more often by participants taking antioxidants. "The AREDS formula is the first demonstrated treatment for people at high risk for developing advanced AMD," Feris said. "Slowing the progression of AMD to its advanced stage will save the vision of many who would otherwise have had serious vision impairment."
