Aging Solution from Oxis

Antioxidants are intimately involved in the prevention of cellular damage -- the common pathway for cancer, aging, and a variety of diseases. The scientific community has begun to unveil some of the mysteries surrounding this topic, and the media has begun whetting our thirst for knowledge. Athletes have a keen interest because of health concerns and the prospect of enhanced performance and/or recovery from exercise. The purpose of this article is to serve as a beginners guide to what antioxidants are and to briefly review their role in exercise and general health. What follows is only the tip of the iceberg in this dynamic and interesting subject.

Endurance exercise can increase oxygen utilization from 10 to 20 times over the resting state. This greatly increases the generation of free radicals, prompting concern about enhanced damage to muscles and other tissues. The question that arises is, how effectively can athletes defend against the increased free radicals resulting from exercise? Do athletes need to take extra antioxidants?

Because it is not possible to directly measure free radicals in the body, scientists have approached this question by measuring the by-products that result from free radical reactions. If the generation of free radicals exceeds the antioxidant defenses then one would expect to see more of these by-products. These measurements have been performed in athletes under a variety of conditions.

Glutathione (gamma-glutamyl-cysteinyl-glycine; GSH) is the most abundant low-molecular-weight thiol, and GSH/glutathione disulfide is the major redox couple in animal cells. The synthesis of GSH from glutamate, cysteine, and glycine is catalyzed sequentially by two cytosolic enzymes, gamma-glutamylcysteine synthetase and GSH synthetase. Compelling evidence shows that GSH synthesis is regulated primarily by gamma-glutamylcysteine synthetase activity, cysteine availability, and GSH feedback inhibition. Animal and human studies demonstrate that adequate protein nutrition is crucial for the maintenance of GSH homeostasis. In addition, enteral or parenteral cystine, methionine, N-acetyl-cysteine, and L-2-oxothiazolidine-4-carboxylate are effective precursors of cysteine for tissue GSH synthesis.

These initial products position OXIS for a feasible entry into the wellness market with a lot of room for expansion. This paves the way for solid partnerships with leaders in the industry with an established customer base or those with the capacity to build one. The ultimate goal is to be regarded as a health partner. For now, it may be penny stocks for OXIS, but with more nutraceutical products lined up (including functional foods like nutrition bars and energy beverages sold over the Internet and through multi-level marketing, infomercials, direct mail, and retail outlets), the future of OXIS is secure and will benefit people all over, allowing them to be healthy and young.

Samsung Wave S8500

Samsung's first bada phone - the Samsung Wave S8500 - is finally here. A few months ago we reviewed a prototype unit, which left us with rather high expectations for the final product. Now that it's here, we are ready to see what Samsung's latest and greatest creation has to offer. Being a full-featured mobile platform however, bada will inevitably face some pretty strong competition in the form of BlackBerry, webOS, Android and iPhone OS. Or will it? According to Samsung, bada is the easy to use type of OS, which will combine the greatness of having rich 3rd-party apps with a user-friendly interface that would appeal to every average Joe out there. So bada is not that much of an opponent to BlackBerry and Windows Phone, than it is to the iPhone, webOS and Android. Congrats, Samsung, you just painted some really tough future for yourself.
The manufacturer's vision is well-represented by its slogan "smartphone for everyone". Well, a bada smartphone for everyone is no doubt what every Samsung executive envisions, but as of now this is surely more of a dream than it is a reality. The question is if, eventually, some day, the bada-based smartphones would really become a part of the general customer's life, similarly to the iPhone now.

Samsung Champ: Featherweight touchscreen

Samsung's latest entry into the bargain touchscreen arena is the Champ. It's a compact phone with a 2.4-inch display, 1.3-megapixel camera, stereo speakers and a 3.5mm headphone jack.The Champ's memory can be expanded with microSD cards (up to 8GB).
You also get access to the Samsung apps store, where you can download java-based games and apps. The lack of 3G or Wi-Fi means that this could take a while.The Champ is due to hit the shops in June and will be available in black, brown, pink or white. No word on the price yet but you'll probably be able to pick up a Champ on pay-as-you-go and free on contracts.

Nokia 6700 Review

Although the world's leading cell phone manufacturer has already pushed out a few touchscreen handsets, it's touch-sensitive portfolio remains relatively tiny, compared to that of some other companies, say Samsung. For good or bad, in this review we'll be looking at a new non-touch phone from Nokia - the 6700 slide. Our journey won't be boring though, as the Nokia 6700 slide is a smartphone, running the Symbian S60 3rd Edition operating system. Not only that, but it's also really pretty, has very good build quality and owns a 5MP AF camera with Carl Zeiss Tessar optics. So, let's not waste any more time and get down to business.

Here's what you'll find in the box:
• Nokia 6700 slide
• Charger
• 2GB microSD card
• Wired handsfree
• Way too short microSD cable
• Extensive user guide

Most of the Nokia 6700 slide's body is made of aluminum, giving it a solid and high-quality feel. In addition, Nokia has come up with a beautiful design, which looks incredibly stylish. Well, at least our silver color variant is stylish, but the Nokia 6700 slide also comes in many other colors, including red, green and blue, which look somewhat more youthful. The in-hand feel of the phone is what it's meant to be - superb, while the sliding mechanism works flawlessly.

The display on the Nokia 6700 slide measures 2.2 inches and has a resolution of 240x320 pixels, which is more than enough for the size. It has a light sensor for automatic brightness handling that we found to work okay. Still, when outdoors you'll have to shield the screen with your hand in order to get a clear view of what's going on.

The keys below the display are nice to use, including the two circular buttons for "home" and "delete" that give the phone a kind of retro appearance. Although a bit on the smaller side, the numpad is well-made and won't give you headaches. Its keys have a well-pronounced click, which makes it easy to feel when you've pressed them.

Surprisingly, there is no volume rocker on the Nokia 6700 slide. On the right side you'll find the two-step camera shutter, the second step of which could work better, and on the top are the 2.5mm headset jack, Nokia charging port and a wisely-hidden standard microUSB port.

A design element that is worth mentioning is that if you want to remove the aluminum back cover, you'll first have to open the microUSB and then press a key that releases the battery door. Although it's a rather unconventional solution, we can't help but admit we like it, as it is a nice touch that gives the phone even more sense of classiness.The back side lets you look at its pleasant-to-the-eye 5MP camera with Carl Zeiss Tessar optics and dual-LED flash.

iBend The phone stand

File this under 'Why didn't we think of this?'. We love a good phone stand, especially now we use our handsets for watching videos and the like, but never before have we seen such a beautifully simple one as the iBend - purportedly for iPhone but any handset of a similar size should work too. Check out the video below for a demonstration of how satisfyingly easy it is.

Like Flat Stanley, the iBend stand is super thin so it'll fit easily in your pocket, diary, wallet or iPhone case - perfect for taking on flights or train journeys. There's a range of designs from the simple black and white (above) to the more colourful artist series featuring custom designs. And the stands are a snip, at just £5.00 for two (international shipping included).

Multitasking phone is their anything like that???

Multitasking has always been a much-needed feature by smartphone users and some of the major operating systems have had it throughout the years. When the Apple iPhone came out, it really redefined how a smartphone should work. However, as all things under the sun, it was not perfect, and one of the biggest argument of its critics was the lack of multitasking. So now that Apple has just announced that multitasking is coming with iPhone OS 4, which will be launched this summer, the most heavily-attacked drawback seems to have become the device's strongest weapon, as it promises fluid system performance and good battery life. But the war is not over yet. Some people say that what Apple demonstrated was actually not a real multitasking, but some limited workaround that will just present a solution for the most popular services. The reason we came up with this article is because we wanted to answer the question of whether or not the Apple iPhone 3GS and the newer models (because the 2G and 3G won't support that functionality) will actually be able to multitask. So here it goes...

Windows Mobile and Symbian S60 are two of the most popular platforms, and one of those operating systems, which have the ability to run multiple third-party processes at the same time. Indeed, these platforms have had multitasking for some time, but there have always been issues with this. Try loading more than two or three heavier 3rd party apps and the phone is a goner. Or worse, it would simply display an "insufficient memory" message and refuse to start the app. Or even worse, it may freeze, so you'd need to waste your time restarting it. It might even require you to remove the battery, as the device won't even restart. Even though these may seem like extreme cases nowadays, this was a common experience maybe just a year ago.

Then we have Android, the platform that is now prospering thanks to its quickly-improving open-source model and high-quality smartphones like the Motorola DROID and Google Nexus One. Of course, Android has multitasking, but let's take a closer look at how it implements it. You can easily reach a total of six currently opened apps. While this limits you, six apps is not that bad.

Glow Phone Concept

Imagine if the whole of your iPhone or BlackBerry glowed different colours when you received a call or text message. Recently Eastman Chemical Company went along to a "design storm" session at Art Center College of Design to come up with ideas on how Eastman's Tritan copolyester, a clear plastic, could be used in consumer electronic devices. Josh Nakaya, Kory Victor, Marcus Koosmann and Grant Poznick came up with the idea of using Tritan to create a 'glowing phone'. By treating Tritan with an optical brightener it would glow when ultra-violet LEDs strike it. As you'll see in the video above, the glow can be limited to the edges of the phone or cover the entire surface. For more info visit the Eastman innovation lab site.

Mobile phone will detect whether you are drunk or not..........

They were originally designed to simply make phone calls without tying callers to one location. But today's cell phones can do so much more, from snapping digital photos to sending text messages to playing video.You can add one more feature to the list: a sobriety test.That's right, cell phones with built-in Breathalyzers are set to hit the U.S. market. So after a night of too much to drink, you can pull out the device to see if you're fit to get behind the wheel.

South Korean manufacturer LG will introduce the LP4100 to the U.S. market sometime in the near future -- though no date is set. The company placed several models on the market in that country last year and already has sold more than 200,000 units.
The phones were previewed at the annual Consumer Electronics Show -- CES -- in Las Vegas earlier this year.Here's how it works: Users blow into a small spot on the phone, and if they've had too much to drink the phone issues a warning and shows a weaving car hitting traffic cones.So they test it and it says don't drive so they leave their car or call the taxi," explained Sung Mee Cho of Seju Engineering Inc.

The company also sells plug-in Breathalyzer adapters for some phones. None of the models tell you exactly how much you may be over or under the legal limit, but it can keep you from making other alcohol-related mistakes.The LP4100 also allows users to set up the phone so on certain nights and after a certain time they do not call certain people in their phone book. Think ex-boyfriend or ex-girlfriend.
If you have a blood alcohol level over .08, the phone will not let you dial that person. So it not only promotes sobriety, but chastity -- and probably your dignity, as well.

.Net will support Nokia N60 platform

It seems like every year we relay the announcement that the .NET platform is going to be available on the Nokia S60. In 2007 the now defunct Red Five Labs was talking about Net60, a version of the .NET Compact Framework. Then in 2008 Nokia announced that Silverlight 2 would be demonstrated at the MIX08 conference. It has been two full years since then and we are just now seeing a public Silverlight for Symbian beta.While the rest of the world is gearing up for Silverlight 4, developers targeting the S60 platform are limited to Silverlight 2. This means going back to Expression Blend 2 and sticking with Visual Studio 2008.

And even in the context of Silverlight 2, the platform is severely limited. Looking at the list of unsupported features, this appears to be more of a tech preview than an actual beta release.

* Cryptography
* Deep Zoom
* Digital Rights Management (DRM)
* Expression trees
* HTML DOM bridge
* JavaScript programmability
* Localization of Silverlight resources
* Reflection
* Sockets
* Visual Basic
* Windows Communication Foundation (WCF)

And these are just the completely unsupported features. There are many common scenarios that lead to undefined behavior or outright browser crashes including having multiple plug-ins on the same page. One can’t even use a single Silverlight plug-in until 200 milliseconds after the onLoad event fires.

Between Silverlight and the S60 operating system is the .NET Compact Framework. Unfortunately developers will not be able to use it; the framework is restricted specifically to running Silverlight plug-ins. And unlike Windows Phone 7, there will be no support for S60-specific features or XNA-based games.

HTC Smart is now available in India.............

The HTC Smart has landed in India where it expects to make some headlines as the Taiwan based company injected its launch with a $1 million marketing campaign. Officially announced by HTC and Bharti Airtel, the budget friendly HTC Smart reportedly “marks HTC's strategic focus on India” – it's looked upon as an emerging market where huge growths are expected to happen. The HTC Smart will hopefully saturate the local market seeing that it's an inexpensive device that features a 2.8” QVGA touchscreen, HTC's own & beloved Sense UI, 3.5mm headset jack, FM Radio, 3.2-megapixel camera, and microSD card support. Even though the HTC Smart is a 3G enabled handset, Bharti Airtel does not currently have a 3G network up and running – yet. The device is expected to be available in about 30 major cities across the country through Bharti Airtel and authorized HTC dealers – it's going for the low price of 9,990 INR ($222). We'll see if HTC hits gold with their move to focus on the emerging market in India.

Sony Ericsson Vivaz Review

With the announcement of the Sony Ericsson Vivaz, the company showed its determination to fight for a chunk of the market of HD video capable cell phones and that such functionality does not necessarily equate to bulky size and hefty weight. The Vivaz is the second model of the “communication entertainment” series, with the Xperia X10 being the first. To win over customers, the device does not rely only on its capable 8-megapixel camera only, but proper multimedia functionality as well.

The Sony Ericsson Vivaz is a high-end smartphone based on Symbian S60 5th Edition (also known as the Symbian^1) and the same personalized interface as the software-updated Sony Ericsson Satio. The Vivaz comes with 3.2-inch resistive screen, Wi-Fi with DLNA, HSDPA, GPS, accelerometer, FM radio, 720MHz processor and OpenGL ES 2.0 support.

What’s inside the box of the Sony Ericsson Vivaz?

• The Sony Ericsson Vivaz
• 8GB microSD card
• Stylus
• Wall charger
• microUSB cable
• Stereo headset (the Sony Ericsson HPM-60/J with 3.5mm jack)
• User guide in several languages

Samsung B3410W Review

Samsung is one of the companies with really strong position in the affordable segment of the cell phone market. Following the rising demand for devices centered on text communication, the manufacturer has recently introduced the Samsung Ch@t B3410W. We cannot call it a brand new handset, since it’s a revamped version of the Samsung B3410 (also known as the Corby Plus) that has been available for some time now. The hardware specifications of both cell phones are almost identical, with but a few differences - the Samsung Ch@t B3410W comes with a built-in Wi-Fi module and newer version of the manufacturer’s proprietary TouchWiz interface.

Unlike the members of the Corby family, the Samsung Ch@t B3410W cannot be referred to as a device with youthful design. It looks austere and the only element that lands color to the buttoned-down design of the handset is its back panel. We do like the proper build quality of the cell phone and the plastic it’s made from does not feel cheap in your hand. There are no wobbly parts and the handset feels solid, not last due to its relatively hefty weight of 114gr.

Similarly to almost all other affordable models equipped with touch-sensitive screens, the 2.6-inch display of the Samsung Ch@t B3410W utilizes resistive technology and features low native resolution of 240x320 pixels. Its sensitivity is decent, but unfortunately, the image quality is far from awesome, with thin, unsaturated colors.

The slider mechanism is quite tight, but that doesn’t mean opening/closing the full QWERTY keyboard involves extra effort or isn’t fast enough. The keyboard itself is, however, not one of the handiest we have used – its buttons are large, but feature limited travel and are just not raised enough, which makes them relatively hard to press. You will probably get used to them in time and will learn what to do in order not to make too many typing mistakes, but using the keyboard will not get enjoyable for sure.

Vodafone launch 'world's cheapest phone'

Mobile phone operator Vodafone has launched what it says is the "lowest-cost mobile phone on Earth".The Vodafone 150, unveiled at the Mobile World Congress in Barcelona, will sell for "below $15" (£10) and is aimed at the developing world.It will initially be launched in India, Turkey and eight African countries including Lesotho, Kenya and Ghana.The UN predicts that mobile ownership will reach 5bn in 2010, with most growth in the developing world.The International Telecommunications Union (ITU) said that demand was being driven by people using their phones to access banking and mobile health services.

Mobile phones have also become an increasingly popular way to transfer and save money in the developing world.For example, a system known as M-Pesa in Kenya, which allows people to transfer money, now has around six million customers.Vodafone estimates that there are more than 11 million customers using banking services on its networks.The Vodafone 150 is designed to bring these services to more people, the firm said.The handset allows voice calls, SMS and has built-in support for mobile payment services. A more expensive version - known as the Vodafone 250 - also has a colour screen and an FM radio, and will sell for $20.Ken Banks, founder of Frontline SMS and an expert in mobile phone use in the developing world said the $15 price tag "lowers the bar, but not by a huge amount".

Opera for mobile phones

I've managed to get a first hand look at the Opera Mini web browser that's been in development for the iPhone. Surprisingly, I was impressed at its performance during our hands-on demonstration at CTIA 2010. The biggest thing that stood out was how quickly a web site loaded on the device – which was obviously running on EDGE speeds as opposed to 3G. Scrolling through a web page looked extremely sensitive – meaning that the slightest movement or flick would make the site scroll in the specific direction very quickly. Text is automatically fitted to the width of the screen to allow easier reading, although the zoomed out view just make text garbled looking.

There are also some other enhancements to make it stand out over some other apps like the automatic syncing of your settings and ability to search for a specific word within a page; something that's not offered on mobile Safari. Additionally, you've got all your common features like copying text and opening up multiple web pages – all are saved when you exit out of the app. Besides that, its overall impressive performance goes to show how useful the web browser can be on the smartphone. Opera has been in the game of providing the best web browser experience on mobile handsets, but their latest efforts with their iPhone app still showcases their ability in continuing to be a leader in this market. As much as everyone wishes to try out this app right now, we'll have to wait until it clears Apple's approval process before anyone can check it out.
