The project marks the first time that "blank slate" stem cells were able to induce hair growth, said Dr. George Cotsarelis, a University of Pennsylvania dermatologist and co-author 카지노사이트 - http://testemkt.buonny.com.br/mundolog/ of the study.

The study was released Sunday on the Web site of the journal Nature Technology in advance of its April publication date.

"We've shown for the first time these cells have the ability to generate hair when taken from one animal and put into another," Cotsarelis said in a telephone interview. "You can envision a process of isolating existing stem cells and re-implanting them in the areas where guys are bald."

The study confirms what scientists suspected for years: Hair follicles contain "blank slate" stem cells that give most humans a full head of hair for life.

Although they are called stem cells, they differ from embryonic stem cells, the research on which has sparked a political debate because embryos are destroyed in the process. Embryonic stem cells are created in the first days after conception - http://www.purevolume.com/search?keyword=conception and give rise to the human body and its more than 200 different types of cells.

Biologists who study hair because of its regenerative qualities said the new study is an important breakthrough. But they cautioned that a baldness cure is still some years away.

"Like with any stem cells, the amount of information needed to get us from a stem to a fully developed organ is a lot," said Stanford University biologist Anthony Oro. "It will require a lot of things to go right and we are still along way off."

Two drugs now on the market, known commercially as Rogaine and Propecia, were first designed to treat hypertension and enlarged prostates but later were discovered to have hair growth as a side effect. Each drug has about $100 million in sales annually.

It's estimated that more than $1 billion is spent each year in the United States combating baldness, mostly through hair transplants.

Alex started selling lemonade four years ago with one stand and raised $2,000 in a single day. Each year brought more stands, manned by friends and volunteers.

The take so far: more than $200,000, including $15,000 brought in last year by the stand at the Scotts' suburban Philadelphia.

"She's determined about anything that's important to her, whether it's what kind of ice cream she's eating or raising money," said Alex's mother, Liz Scott - http://www.encyclopedia.com/searchresults.aspx?q=Liz%20Scott . "I think (the stand) does keep her going sometimes."

This year, 카지노사이트 - http://shoolinbusiness.com/ on Saturday, all 50 states will have "Alex's Lemonade Stands" open for business. Alex's father, Jay Scott, estimates that as many as 1,000 stands will be pouring the icy cold concoction.

"I think it just shows, you read a lot of bad stuff in the news, it shows how good people really are," Jay Scott said.

Two days before her first birthday, Alex was diagnosed with neuroblastoma, a type of cancer that originates in certain nerve cells. The survival rate for high-risk neuroblastoma, which Alex has, is just 40 percent.

"Alex would have died many years ago if it wasn't for newer experimental therapies, and I think that's something she and her parents recognize," said Dr. John Maris, who has directed Alex's care at the Children's Hospital of Philadelphia. Neuroblastoma is diagnosed in about 700 U.S. children every year.

Though excited about Saturday, Alex has been drained by the chemotherapy and radiation being used to treat a new attack of tumors, her mother said. After seven years of treatment, her cancer is considered incurable.

"She's tired. She's exhausted," Liz Scott said. "Her future has always been uncertain, but I don't think any of us — me, my husband, her doctor — has felt this pessimistic before.

Because of her frail condition, her parents and doctor have encouraged Alex to cut back on her fund-raising activities. But she insisted on appearing on a television morning show last Friday to publicize the fifth annual "Alex's Lemonade Stand" day

After last year's stand, the Scotts put out a call over the Internet for help in every state. Advertising fliers were posted on Alex's Web site, and the Scotts sent out dozens of coupons for free lemonade mix

Alex has given $150,000 to her Philadelphia hospital. Thousands more have gone for research in Connecticut, Michigan, Texas and California. This year's take will also go for research, but the family hasn't decided yet where

"Alex will have a big say in that," Liz Scott said. "She always does.

Some days Alex feels good, like earlier this week when she saw the new Harry Potter movie. Other days she doesn't. Every day she lives knowing many of her friends have died of neuroblastoma

r>

r>
Her mom calls Alex "the bravest person I know," and she holds out hope her daughter can overcome her disease

"I'm obviously very proud of her, but it's more than that," Liz Scott said. "I feel privileged to be her mom. I admire her."

Now his son, Luis Angel Valdivia, and union representatives are appealing to companies to take the commonsense measures that could have saved his life.

"There isn't much I can do now, but I don't want other workers to go through what I'm going through now," said Valdivia, who watched his 53-year-old father faint among the grapevines in a field outside Bakersfield, and die in his car last Wednesday, as he sped toward the hospital seeking medical help.

California's grape harvest happens in the middle of summer, when temperatures in the state's fertile Central Valley often soar past 100, and lead to frequent complaints of dizziness and nausea among workers- the symptoms of heat stroke, said Arturo Rodriguez, president of the United Farm Workers.

"There is not a whole lot we can do, except put pressure on the growers to give them what they need to take care of their bodies," said Rodriguez. "They just need to use common sense. If it's 100 degrees out, workers need more breaks, and more water, than the minimum required."

The state's Division of Occupational Health and Safety requires employers to give workers two 10-minute breaks in one day, plus a half-hour lunch. Cool water should also be provided. Workers confirmed there was enough water for them last Wednesday.

But there are no additional safety measures required — longer breaks, shade, salt tablets — to help workers stay hydrated when the heat reaches into the 90s and past 100, said Susan Gard, a spokeswoman for the state occupational safety program

r>

r>
Employers are only required to report cases of heat stroke or other illnesses if the worker requires more than first-aid care, Gard said

r>

r>
"Unfortunately, we only hear about it when it becomes a tragedy, if there is a 24-hour hospitalization or a death," she said

r>

r>
The state database with numbers of heat stroke victims was not immediately accessible, Gard said

r>

r>
The agency targets agriculture for additional enforcement because it recognizes the industry is dangerous, Gard said. It publishes an employers' guide on agricultural safety that mentions heat stroke as a cause for concern, and holds farm worker forums to educate them on their rights on the job, she said

r>

r>
When temperatures soar and the men and women who pick produce work more than 10 hours a day to keep up with the season's peak workload, the minimum might not be enough, said Keith Jilmetti, a workers' compensation lawyer who is helping the family

r>

r>
"The California labor code says it's the duty of employers to provide a safe and healthful work environment," said Jilmetti. "If they have to go above the minimum (to provide for a safe working environment) so be it.

What began as an immigrant family's small business has grown to a multinational conglomerate that works with growers in California and around the world, from Chile and Mexico to New Zealand and China

"We have a great relationship with our people, and they come back year after year," the company's president, Joe Giumarra, said Monday. "We did the best we could to respond adequately.

He said heat stroke had not yet been determined as the cause of death in Valdivia's case, and autopsy results were expected in four to six weeks

The foreman supervising the field where the father and son had been working initially called for medical help, but then canceled the call when the older worker regained consciousness, although he was never able to talk or walk on his own, his son said

An Environmental Protection Agency official responded that the study misconstrued EPA data and created no reason for the government to change its recommendations on eating wild freshwater fish - http://de.bab.la/woerterbuch/englisch-deutsch/freshwater%20fish . An official of a commercial fish trade group said the study examined data on recreational fishing, not farm-raised freshwater fish found in supermarkets.

About 2,500 fish collected from 260 bodies of water from 1999 to 2001 showed the presence of mercury, the report said. The toxic metal can cause neurological and developmental problems, particularly in young children.

The report was prepared for Clear the Air, a joint campaign of the Clean Air Task - http://www.trainingzone.co.uk/search/Air%20Task Force, 카지노사이트 - http://sunmaster.my/ the National Environmental Trust and the U.S. Public Interest Research Group. The study recommended more restrictions on mercury emissions from coal-fired power plants.

Seventy-six percent of the fish samples exceeded EPA's mercury exposure limit for children of average weight under the age of three, the report said. And 55 percent contained mercury that exceeded the limit for women of average weight, it said. The report assumed that people in both groups ate fish twice a week.

The high levels of mercury raise the risks of neurological problems in young children or in fetuses of women who ate the fish, said Emily Figdor, a clean air advocate at U.S. PIRG and the study's author. She could not say how many more such cases could be expected.

Although the EPA agrees that mercury exposure is a serious public health issue, the Clear the Air study misused EPA's exposure limits, said EPA spokeswoman Cynthia Bergman.

The advocacy group, in saying the mercury exceeded safe levels, applied standards the EPA set very low to be on the conservative and safe side of any possible errors, Bergman said. The study also based its estimates on material not from EPA, taking its consumption estimates from the American Heart Association's recommendation that people ought to eat two fish meals a week, she said.

The report does not create a reason for the EPA and the Food and Drug Administration to change the guidance the agencies gave in March on eating wild fish, Bergman said. The agencies said people should check with state or local authorities to learn the safety of the fish. If no such advice is available, people should eat no more than one six-ounce portion a week and should eat no other fish, they said.

Consumers who buy their freshwater fish at markets should not be alarmed about the study, which looked at sources of recreationally caught fish, said Bob Collette, vice president for science and technology at the National Fisheries Institute, a fish industry trade group.

Most freshwater fish that people eat is raised on farms and is not a danger, Collette said.

The report said reducing mercury emissions from power plants is crucial to reducing unsafe levels of mercury in the fish. It criticized the Bush administration as planning to "delay even modest reductions in mercury from power plants until after 2025."

The EPA's Bergman said the administration had taken a big step forward by deciding to regulate the emissions, but she said technology needed for plants to make the cuts had not yet proved itself. U.S. PIRG's Figdor disputed that, and said some states were imposing earlier deadlines on emissions control than the EPA has planned.

Wound-care clinics around the country are giving maggots a try on some of their sickest patients - http://www.channel4.com/news/sickest%20patients after high-tech treatments fail.

But Dr. Ronald Sherman's maggots are getting more attention since, in January, they became the first live animals to win U.S. Food and Drug Administration approval — as a medical device to clean out wounds

But maggots do more than that, says Sherman, who raises the tiny, wormlike fly larvae in a laboratory at the University of California, Irvine. His research shows that in the mere two to three days they live in a wound, maggots also produce substances that kill bacteria and stimulate growth of healthy tissue

Still, "it takes work to convince people" — including hospital administrators — that "maggots do work very well," said Dr. Robert Kirsner, who directs the University of Miami Cedars Wound Cent

"They'll probably be easier to use now that they're FDA-approved, and we'll talk about it more and think about it more," Kirsner said. He estimates he uses maggots in about one in 50 patients where conventional therapy alone isn't enou

Gov. Rod Blagojevich on Friday signed a bill barring people from filing lawsuits claiming - https://www.b2bmarketing.net/search/gss/lawsuits%20claiming a restaurant caused weight gain, obesity or other health problems.

4585)_听" style="max-width:400px;float:left;padding:10px 10px 10px 0px;border:0px;">Illinois joins 11 other states to enact such laws, 10 of which have been signed since March, according to the National Restaurant Association. Louisiana led the way by enacting a "frivolous-lawsuit" law last summer.

Blagojevich said signing the "Illinois Common Sense Consumption - http://www.answers.com/topic/Sense%20Consumption Act" promotes personal responsibility.

"Obesity is a serious problem in Illinois," Blagojevich said in a prepared statement. "But blaming a restaurant for weight gain is not the answer."

A federal judge in New York last year dismissed two lawsuits alleging Oak Brook-based McDonald's Corp. had caused obesity and related health problems in thousands of children. The judge said the law shouldn't try to protect people from their own excesses and that other factors besides fast food could have caused failing health.

"We must put the focus on healthier lifestyles and nutritional balance instead of costly lawsuits and litigation that only serve to clog up our courts and drive up the cost of a meal," said the bill's sponsor, Sen. John Cullerton, 카지노사이트 - http://radiodialfmcomar.crearradio.com/ D-Chicago.

The federal government estimates 6 percent of Illinois residents and nearly 8 percent of Medicare recipients are obese, according to the governor's office.

Similar measures still are pending in six states, according to the restaurant association, but nine other states considered legislation this year but killed it.
