Green tea could cloud Olympic doping tests

LONDON (AP) ? Olympic doping officials are considering whether to tweak their tests after a recent British study showed green tea might hide testosterone from the standard test used to spot it.

The study was a test in a lab dish so scientists aren't sure if the effects will be the same in people. But some experts say the results are intriguing enough that Olympic testing could be updated to include that possibility.

"It's interesting that something as common as tea could have a significant influence on the steroid profile," said Olivier Rabin, scientific director of the World Anti-Doping Agency, or WADA. He said other foods and beverages, such as alcohol, are also known to muddle test results.

"We may need to adjust our steroid (test) to allow us to exclude whether a test is modified by food or training or disease, before we can say that it's doping," Rabin said. He said they might have to raise their normal threshold for what is a considered a legal amount of testosterone to allow for any such interference.

In the study, researchers added green and white tea extracts ? or catechins ? to testosterone and tested whether the enzyme that usually detects testosterone in the body could still identify it. Tea seemed to reduce the testosterone concentration by up to 30 percent and appeared to work best when testosterone was only slightly higher than normal. Similar results have been found in rodent studies, Rabin said.

Experts say athletes taking testosterone for doping purposes typically have 200 to 300 percent more in their bodies than normal.

WADA has tight controls on other commonly consumed substances like caffeine. It bans diuretics that could mask drug use and warns athletes about taking nutritional supplements, which could be spiked with banned drugs.

The researchers said it was too early to tell what the effect of green tea might be in humans, but said other beverages or foods likely produced similar effects.

"There's no reason to think we just happened to pick the only food in the world that does this," said Declan Naughton of Kingston University, who published the green tea research with colleagues in the journal, Steroids.

Naughton said the green tea contains catechins, also found in white tea, which seem to stop an enzyme involved in detecting testosterone. By preventing that enzyme from working, testosterone largely goes unnoticed in the body and doesn't get passed into the urine ? where officials usually test for the hormone.

Charles Yesalis, a doping expert at Pennsylvania State University, said officials needed to react quickly.

"Athletes will not wait for the clinical trials," he said. "I'll bet there are already lots of athletes out there drinking loads of green tea," he added.

Yesalis said many scientists were aware of foods that could skew drug tests but would not talk publicly about them. "There's no sense helping out the doping athletes by telling them what to eat," he said.

Yesalis was unconvinced that new tests could solve the problem. "There's too much scientific uncertainty that can cloud the results," he said.

WADA's Rabin said all atypical results from doping tests involved an expert analysis, not just a lab result. "There's a human interpretation of the data," he said, explaining that officials regularly accounted for potentially troublesome results by considering things like intense exercise, jetlag and diet.

Rabin also said it might be possible to test for testosterone in blood rather than the standard urine test.

Some experts said the limited effects of foods like green tea on masking illegal drug use would be too small to help doping athletes. "You would probably need to drink the tea continuously to get any sustained but minor effect," said Andrew Kicman, head of research and development at the Drug Control Centre at King's College London, which is providing the anti-doping laboratory for the upcoming Olympics.

"It would be a very foolish athlete who's thinking of doping with testosterone and thinks he could drink white or green tea to beat a drug test," he said. "And I personally wouldn't want to drink nine cups of tea on the day of a race."

Internet communications bandwi?

Written on April 7, 2012 ? 11:41 am | by admin

Internet communications bandwidth requirements continue to keep grow at about 50% each year. The demand for Broadband Internet by cable has been growing hence fast, thWildBlue ue has stopped having orders in parts of the United States.

The demand is likely to grow at a faster rate within the near-term. HIGH DEFINITION signals require 4-5 instances as much bandwidth intended for transmission as standard meaning video, despite having sophisticated MPEG-4 coding. By the year 2010, forecasts call for 80-90% of all Internet traffic to be video transport.

There are currently over 600, 000 satellite Net subscribers in United states, usually inside the more remote locations where broadband Internet is certainly otherwise unavailable. The two times a new Internet satellite has launched, a large increase in satellite Internet customers has followed, but within a couple of months, capacity had been sold out in primary geographic places, capping subscriber growth.

Current satellite tv systems aren?t intended for the high bandwidth applications that people requirement, such as HIGH DEFINITION, graphics, Voice over internet protocol, and peer-to-peer mlm.

?It does not have to possibly be that way. Daily consumer Net interactions involving high-bandwidth pursuits like video and multimedia were not area of the plans any time earlier satellite services were designed. We are aiming to provide consumers a vastly increased experience in line with the innovative technology on the market. These new capabilities are not only technologically pretty feasible, they?re furthermore affordable, ? explained Mark Dankberg, TOP DOG ViaSat.

ViaSat provides plans to address the necessity. ViaSat-1 is certainly scheduled for launch this year. How much bandwidth allowed by ViaSat-1, built with ViaSat?s ?SurfBeam? social networking system, is unequalled. Total throughput is manufactured above 100 Gigabits per second, which is even more capacity than the current North American number of two-way Ka, C as well as Ku band put together. ViaSat-1 should drastically improve the high quality, capability and accessibility to high-speed Internet cable services for U. S. as well as Canadian customers.

This season, Ka-Sat might launch a satellite to supply similar service throughout Europe.

The newest satellites is likewise utilized to provide Internet services, TV (including HDTV), cell Internet, and defense satellite communications. Through 2010, 60% of TV receivers will use a Satellite transmission, up out of 15% in 2002. ViaSat terminals use a networking technology that uses satellite bandwidth more efficiently, called DOCSIS (Data Over Cable connection Service Software Specifications), lowering the price of Web service to customers. The terminals incorporate satellite modems as well as Ka music group transceivers. The high throughout of ViaSat-1 makes it well suited for transmitting new movie applications requiring ultra great bit rates such as HDTV, HD digital cinema, along with 3D TELEVISION SET.

DOCSIS also contains technology that includes rain fade, a reduction in signal power caused by heavy rainfall. The ViaSat system automatically responds to rainfall fade with uplink strength control and adaptive data coding methods.

ViaSat-1 as well as Ka-Sat will offer 10-15 times the capacity of Ku group of musicians satellites through frequency recycling by using a technological innovation called ?spotbeams?. Spotbeams are like the searchlight. Rather than sending a sign across the country, spotbeams focus a signal on an place 50-100 miles within radius. Since the frequency is focused on a constrained area, the identical frequency spectrum could be reused for just a different place.

Median DSL speed inside the U. Ring. is 768 KBPS. Median Internet swiftness over cable is approximately 4. 5 various MBPS. ViaSat-1 can price a basic service at two MBPS, raising cable to about the 80th percentile associated with DSL. Premium strategies would easily surpass the most effective DSL provider, and put satellite television well above the present median for cable.

Eutelsat will position Ka-Sat in the same satellite neighborhood as three current Hotbird Ku-band satellites at 13 degrees Far east. By setting Ka-Sat with these send out satellites they shall be able to bundle broadcast as well as broadband services. Customers in Europe should be able to acquire TV inside the Ku-band and receive and transmit broadband expert services in the Ka-band through a particular dual-frequency antenna.

ViaSat-1 calls for a collaborative effort in between ViaSat, Loral, TeleSat, and also Eutelsat. Eutelsat Marketing communications is the holding enterprise of Eutelsat Nasiums. A. With a current 24 geostationary satellites that serve European region, in addition to the Midsection East, The african continent, India and substantial parts of Asia and the Unites states, Eutelsat is one of the planet?s three leading satellite providers in terms of revenues. Eutelsat?s satellites transmitted over 2, seven-hundred television channels, that more than 1, 000 channels transmitted from its HOT FOWL satellite which serves over 120 million cable as well as satellite homes in The european countries, the Middle East and North Cameras.

Loral had been selected to build the actual ViaSat-1 high capacity broadband satellite. Loral is investing in the Canadian coverage portion of the satellite pending Telesat Europe (which is 64 per cent owned by Loral) using the capacity for the purpose of Canadian services.

The satellite is planned for the purpose of Telesat?s 115 West longitude orbital slot as well as Telesat will also give telemetry, tracking as well as control (TT&C) operations for your satellite.
