Vitamin E - An Anticatabolic Agent-Vitamin

In a study performed at the German Sport University in Cologne, scientists examined 32 rats that had one of their hindlegs immobilized for 8 days, similar to the way a fractured bone is cast. The other leg was free to move. One group received six intraperitoneal injections of vitamin E in the form of alpha-tocopherol acetate at a dose of 60 mg/kg twice a week. The injections started 2 weeks before the immobilization period. After the treatment period, the animals were sacrificed and their muscles examined.

Levels of oxidative stress were less in the vitamin E group. This supports the role of vitamin E as a potent antioxidant. Muscle fiber measurements of the soleus muscle revealed a 35% decrease in muscle fiber cross­sectional area in the immobilized muscles of animals that did not receive vitamin E. However, the vitamin E-treated group showed only a' 12% loss of muscle fiber cross-sectional area.

This study clearly shows that vitamin E plays a role in modulating skeletal muscle mass. In this case, the muscle studied was the predominantly slow-twitch (>90%) soleus muscle. Most muscles in the human body are 50% fast and slow. Would this muscle-protective effect of vitamin E be similar in those muscles that have a greater percentage of fast fibers? Certainly, one should be cautious of over-extrapolating from rodent data to the human condition.

Nevertheless, this study has interesting implications for human athletes (particularly strength-power athletes) who often succumb to injury and have to rest a body part or the entire body for prolonged periods.

How much vitamin E should you consume

Right now, scientists do not know the optimal dose for athletes, but many individuals who do not experience any ill effects take doses as high as 200-400 IU per day regularly. Further, you need these doses to attain some degree of cardiovascular disease protection.

Some things in life never really go out of style. Well, they change forms and take on new looks, but they remain. One of such time defying inventions is the radio. No matter what skeptics would have you believe, the radio is very much alive and kicking even in this era of digital entertainment. Of course, the persistent existence of the radio has subjected it to some changes. Bulky radios or even the smaller, battery-powered transistors are becoming increasingly rare with every passing day. But the core essence of radio technology, that of sound and music being transmitted from a central station, still survives and is gaining in strength and popularity with passing time. Let’s investigate this amazing phenomenon.

The radio in the 21st century has taken on a new avatar. It has merged with possibly the most powerful medium of modern times, the Internet. The result? E-radio, (what else?) In this era of e-mails, e-shopping and e-commerce, e-radios, or Internet radios as they are often called as, are a natural occurrence. We are not surprised, and nor should be you! If you’ve been reading the writing on the wall, you already knew that it had to come someday. So, the good news is, it’s here! And how! Let’s take a closer look.

Internet radio networks are on the rise and the reason is not hard to understand. Much of their popularity can be attributed to the huge proliferation of Internet technologies. It is, however, interesting to note that Internet radio, however, is not a very novel innovation. In other words, Internet radio networks have been around for quite a while now. It is only recently, with the proliferation of Internet technology and faster connectivity, that the phenomenon called Internet radio has truly come of age. Today, the listener is pampered with a bevy of channels (or stations), catering to specific areas of interest. This is becoming a standard feature of Internet radio networks that serve music online. The listener can tune into any of dozens of stations covering such genres as Classic Rock, Alternative Rock, Indie Rock, Jazz, 80s music, 70s music, Oldies, New Age, Reggae, Country, Latin, Euro, Ambient, Lounge, Progressive, Techno and what not. Hours and hours of uninterrupted music at no cost – that’s the magnitude of the entertainment provided by Internet radio networks.

Among the most popular Internet radio networks are the ones that feature Internet Talk Radio. Streaming talk shows and discussions on a wide range of subjects have made them popular among serious listeners or those who carve for something more than just music from their e-radios. Internet talk radio programs host various talk shows with specialists on different subject matters who anchor the show. While traditional radio broadcasters have often used the Internet to advertise or promote their shows, Internet radio technology has actually revolutionized the concept and simple programming requirements have taken it to the extent where individuals, organizations or anyone for that matter, can easily host their own Internet talk radio station from the comfort of their home.

Internet radio networks like Voice America make it easier to host your own Internet talk radio show. Such Internet radio networks not only provide you with the technology to host your Internet radio show but also give you a complete package of Internet streaming media broadcasting, proven support services in web, marketing, and interactive solutions that help you to make your mark and your presence known to the ever increasing Internet audience. If you are planning to host your own Internet talk radio, it’s worth contacting Internet radio networks like Voice America.

Wireless

Wireless technology for Internet access is rapidly spreading throughout the world. It will not be long until every corner of the globe is connected to the Internet via Wi-Fi. Portable laptop computers are produced, manufactured and released in a steady stream with upgraded 802.11 a/b/n connectivity chipsets, enabling technical and non-technical users to connect to the Internet via speedy wireless connections. Bluetooth technology allows a wireless protocol for connectivity and is specifically designed for electronic applications less than 30 feet in distance from the host site.

Wireless connectivity is used by professionals in IT, in large business organizations and for home use. Connecting to the Internet with a wireless connection is fast becoming the preferred way to access the Internet. The convenience of wireless connections and the practicality of the initial set-up and maintenance of wireless services is an industry that is growing and developing rapidly as Bluetooth technology expands. Most peripherals can be connected wirelessly to a desktop computer or notebook using Bluetooth technology, creating a cleaner and more practical work environment for all users. Understanding wireless security encryption and developing a secure system of connectivity is essential to prevent data theft and establishing sound security measures within wireless connection.
