Free Radicals

Several years ago while waiting for my lunch being served at the Sushi King near Bukit Bintang Kuala Lumpur, I was approached by a young Malaysian Indian asking me whether I know about a so called free radicals. So as not wanted to be disturbed assuming that he is a salesman trying to sell products, I said that I have heard about it even though I had not the slightest clue as to what it meant.

Now, after recalled it, I realized how stupid I was for not giving him a chance to explain about it. If you are concern about you health, you should know this too.

What is free radical?

Free radical is any atom or molecule that is highly reactive and unstable because they contain unpaired electron in their molecular structures. In order to become stable, they attack and steal electrons from other molecules. This attack spontaneously generates another unstable free radical molecule, starting a chain reaction that damages cellular function, eventually leading to the cells' death.

Scientists call free radicals the underlying cause of many chronic diseases. Dr. Bruce Ames, Ph.D., a well-known scientist in the field of antioxidants, estimates that just one cell in the human body is hit about 10,000 times a day by a free radical. If that’s multiplied by the trillions of cells in our body the magnitude of this activity is tremendous.

Do you know how they destroy your health?

Free radicals kill cells, damage body tissues, destroy enzymes, attack DNA and produce toxic chemicals.

A wealth of scientific evidence has determined that the body's formation of unstable oxygen molecules (free radicals) is the cause of various diseases such as heart diseases, strokes, diabetes, arthritis (joint pain), sinusitis, vision problems (cataracts), neurological impairments, high blood pressure and cancers.

How are free radicals formed?

They may formed through one of these:

1- Unhealthy food - fatty diet made up of processed food, fried food, barbecued and charbroiled food.

2-Alcoholic beverages.

3-Cigarette.

4-Stress - all chemicals and some endocrine hormones create free radicals.

5-Toxic chemicals in pesticides and insecticides.

6-Ultraviolet (UV) rays.

7-Environmental pollutants and contaminants.

8-Endurance exercise.

How to prevent or minimize the damage done by free radicals

Antioxidants were found to be the best solution in solving free radicals problem. Antioxidants are compounds that help to inhibit the many oxidation reactions caused by free radicals thereby preventing or delaying damage to the cells and tissues. They neutralize free radical by donating their own electron and don't turn into free radicals because they are stable in either form, ending the electron-stealing reaction.

It is well known that fruit and vegetables (Vitamin C and E) are good sources of antioxidants. Anthocyanins (natural substances that provide pigmentation-[color] to fruits and vegetables) serve as a powerful natural antioxidants. That is why health experts recommend strongly for us to consume at least 5-9 servings of colorful fruits and vegetables a day to replenish our body's antioxidant supply.

Here is the rank of antioxidants by potency

1-Anthocyanin

2-Grape Seed Extract, Pine Bark Extract

3-Coenzyme Q-10

4-Alpha Lipoic Acid (ALA)

5-Vitamin E, Beta-Carotene

6-Vitamin C

As well as eating more fruit and vegetables, antioxidant intake can be topped up by drinking more tea (which also has been found as a natural resources of antioxidants), helping to promote overall health and well-being.

See the video below..

The flipping action seems to simulating the reading experience of paper-based publications but now its on our computer screen and of course we can put it on our site or blog like mine. Some commercial sites like flipviewer also use this kind of e-browser features for impressive 3-D looks.

However for my uploaded document, since it is in Arabic, it supposed to flip from left to right. Issuu should look into this issue since some publications like in Arabic or Japanese should flip from left to right.

GPS Navigator

Thing get much, much easier today. Now we need not to bring along a printed map (Atlas) when we are traveling to any place on earth without getting lost. With the help of GPS (Global Positioning System) we can rest a sure that our journey to a destination are on the right direction. What we need is only a GPS receiver.


This Global Positioning System (GPS) is a U.S. space-based radio navigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis -- freely available to all. For anyone with a GPS receiver, the system will provide location and time. GPS provides accurate location and time information for an unlimited number of people in all weather, day and night, anywhere in the world. GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, scientific uses, and hobbies such as treasure hunting.


These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers. Soon GPS will become almost as basic as the telephone and may become a universal utility.


Last month while preparing to attend a marriage ceremony at the place which I have never been before, my relative has introduced me to a personal navigator. I found it is very useful.




I have reached my destination without any problem. The voice assistance prevented us from taking any wrong direction since it reminds us about up coming junction or route that we should take in advance. The view of the upcoming roads, junctions, roundabouts and sharp bends give us as an early warning so that we can drive carefully and safely. The time of arrival to our destination is also shown according to our speed.

Coming Back

I have been blogging seen 2005 through my blog namely Roshidan's Cyber Station at http://roshidan.blogspot.com/. Unfortunately my blog has been removed by blogger.com because there were malicious codes in it probably came from the affiliates or the advertisements (I'm not sure of it) since I tend to put so many of them on my site.

When it was removed I have tried several time and ways to get it back from blogger.com but failed may be because I did it the wrong ways. If anybody out there who has experienced the same problem and has recovered their sites, please teach me how you did it.Now I am coming back, leaving my frustrated feel behind with a new blog.

See you around!
