This larn was the low to amount the personalty of alkaloid on subjects during sane conditions. Time more somebody unnatural the personalty of alkaloid on blood push, effects were usually tried in a disciplined environment. Most of these studies compared a upper dosage of alkaloid to no dosage. Time these were encouraging in establishing the corporeal personalty of alkaloid, the subjects were separate from their inbred activities. This think monitored 19 habitual potable drinkers during their regular package. Gore somaesthesia readings were appropriated throughout the day and correlated with ego reportable evince a figure or quint portion increase in slaying somatesthesia is not necessarily inordinate, it can guidance to complications over dimension.

* Batches already in existence may be reviewed

* NIH says rules reflect broad public support (Adds reaction from Republican opponent, paragraph 9)

WASHINGTON, July 6 (Reuters) – The U.S. government released new rules on Monday governing federally funded research on human embryonic stem cells, loosening some ethical requirements that scientists said could have cost them a decade of work.

The rules, which take effect on Tuesday, keep many existing restrictions on the research. U.S. federal funds may still not be used to actually make the cells using human embryos — only to work with the cells after someone else has made them.

But the National Institutes of Health, which issued the rules, eased some of the measures in the initial guidelines drawn up in March, including the so-called “informed consent” requirements meant to ensure that people who donated embryos for research knew exactly what they might be used for.

“We allow a case-by-case review,” acting NIH director Dr. Raynard Kington told reporters in a telephone briefing.

In March, President Barack Obama lifted restrictions on human embryonic stem cell research that had been put in place by his predecessor, former president George W. Bush and asked the NIH to draw up new guidelines.

Stem cell company stocks did not move much on news of the new rules, in part because the changes mostly affect academic researchers who rely on federal funding for their work.

The NIH guidelines take into account many of the arguments put forward during nearly 10 years of debate over how best to use the potential of human embryonic stem cells, which have the power to give rise to all the cells and tissues in the body and which supporters hope can transform medicine.

Opponents say it is wrong to destroy human embryos for any reason.

“The administration’s decision to dramatically expand the number of stem cell lines derived from human embryos and create incentives for the destruction of human life is a provocative step beyond what the president proposed just months ago and yet another sign that he has quickly retreated from his promise to be a president for all Americans,” House of Representatives Republican leader John Boehner said in a statement.

However, over the years Congress reached a middle ground, with many social conservatives such as Utah Republican Senator Orrin Hatch supporting such research if it used embryos left over at fertility clinics.

BROAD PUBLIC SUPPORT

“The guidelines reflect the broad public support for federal funding of research using human embryonic stem cells created from such embryos based on wide and diverse debate on the topic in Congress and elsewhere,” the new rules say.

They limit such research to these in vitro fertilization or IVF leftovers but also loosen restrictions on using human embryonic stem cells made in other countries.

In April when the initial guidelines were published some scientists said the “informed consent” rules on educating embryo donors were so strict that they might force labs to discard valuable stem cell batches, called lines.

“The draft guidelines that were released were so restrictive that I feared the vast majority of lines would be excluded,” Dr. George Daley of Harvard University in Massachusetts said in a telephone interview. He said the revised rules answer his concerns.

“It is the most that the administration can offer under current law,” said Dr. John Gearhart, a stem cell expert at the University of Pennsylvania. “There are many ‘new’ cell lines that have exceptional properties and have been maintained under better conditions that will meet the criteria of use.”

The rules create in effect the first official federal oversight of human embryonic stem cell research, the American Society for Reproductive Medicine said.

They said younger adults — those aged 35 to 45 years old — have experienced the steepest declines in cancer death rates, but all age groups have shown some improvement.

“Essentially, the younger you are, the faster your rates are declining,” said Dr. Eric Kort of the Helen DeVos Children’s Hospital in Grand Rapids, Michigan, whose study appears in the journal Cancer Research.

The study uses a different way of looking at cancer death rates that measures improvements in cancer deaths by age.

U.S. government estimates suggest there had been little improvement in cancer death rates throughout the 20th century, with rates only beginning to improve in the mid-1990s, Kort said. But that does not tell the whole story, he said.

“The way that these statistics are traditionally reported is they have averaged all of the age groups together to get a composite rate,” Kort said in a telephone interview.

“The problem with that is because most cancer deaths occur in older Americans, the average heavily emphasizes the experiences of older people. It’s like watching the caboose of the train to tell when the train is changing direction,” he said.

Instead, Kort’s team looked at improvements in cancer deaths among groups of individuals born in five-year intervals starting in 1925.

Using that method, Kort said, “Everyone born since the 1930s has enjoyed a decreased risk of cancer death, at every age.”

People in the youngest age group — those aged 35 to 45 — had a greater than 25 percent decline per decade in cancer deaths, he said.

Kort said cancer prevention — including smoking cessation efforts — have played an important role in these trends.

“We’re also benefiting in profound ways from progress we’re making in early detection and better treatments. Some of these advances benefit younger people first,” he said.

In childhood cancers, advances in treatments for leukemia and lymphoma mean many more people can survive cancers that were once considered a death sentence.

And better screening for cancers that occur in older age, such as mammography in breast cancer and colonoscopy for colon cancer are spotting cancers at an earlier stage, when they are easier to treat.

Cancer remains the No. 2 killer of Americans, with about 560,000 deaths annually, topped only by heart disease, according to the American Cancer Society.

Following are some facts about stem cells:

* Stem cells are the body’s master cells, the source of all cells and tissue, including brain, blood, heart, bones and muscles.

* Embryonic stem cells come from days-old embryos and can produce any type of cell in the body.

* Scientists generally harvest embryonic stem cells from embryos left over after in vitro fertilization attempts at fertility clinics. They can also be produced using cloning technology but the new U.S. rules allow for federal funding only of work on surplus IVF embryos.

* Scientists hope to harness the transformational qualities of stem cells to treat a variety of diseases, including injuries, cancer and cystic fibrosis.

* The issue is controversial because some people believe the destruction of any human embryo is wrong.

* Several companies are pursuing stem cell research including Geron Corp. which last week teamed up with General Electric Co to use stem cells to test new drugs for toxicity.

* Other companies involved in stem cell research include Stemcells Inc., Advanced Cell Technology, NeuralStem, Aastrom Biosciences Inc., Reneuron Group Plc., Thermogenesis, Osiris Therapeutics Inc, Neostem Inc., Cytori Therapeutics Inc., iZumi Bio Inc., and International Stem Cell Corporation.

*U.S. legislation called the Dickey Amendment forbids the use of federal funds for the creation or destruction of human embryos for research, but new U.S. policy allows federally funded researchers to work with cells someone else had taken from an embryo.

* The issue does not fall clearly along party lines and some conservative Republicans who oppose abortion have backed broader federal funding of embryonic stem cell research for years.

* Britain, Belgium, Sweden, Canada and New Zealand encourage embryonic stem cell research. Austria, Lithuania and Poland have laws banning most human embryonic stem cell research.

* Researchers have discovered how to make embryonic-like cells from ordinary cells, called induced pluripotent stem cells. Opponents of embryonic stem cell research say research can focus on this field, but most scientists agree that all approaches must be pursued.

Hwang, once a scientist with rock-star like status in South Korea for his research that brought the country to the forefront of stem cell studies, is facing trial on charges of fraud, misusing 2.8 billion won ($2.25 million) in state funds and violating bioethics laws.

Prosecutors said Hwang brought shame to the country and harm to scientific research in South Korea.

“The disappointment felt by the (Korean) people is enormous,” one of the team of prosecutors told the court.

Hwang, who has apologized for fraud in his team’s work, has denied any wrongdoing and said he was duped by junior researchers into believing the landmark results

Lee Bong-gu, a lawyer for Hwang, said: “These people, including the prosecutors are trying to tear apart Hwang’s precious scientific evidence.”

Hwang’s trial at a nondescript Seoul court has been going on for about three years, and could stretch into a fourth, legal experts said. It has been bogged down in the technical testimony from scores of scientists about the research done by his team.

His supporters have staged emotional rallies over the years and filled the court for each of what are typically monthly hearings, saying Hwang is a scientific savior who should be given a second chance.

Hwang’s team was thought to have made two major breakthroughs in the field by cloning stem cells and tailoring them to a specific patient, which raised hopes of generating genetically specific tissue to repair damaged organs or treat diseases such as Alzheimer’s.

Stem cells are the body’s master cells, giving rise to all the tissues, organs and blood. Embryonic stem cells are considered the most powerful kinds of stem cells, as they have the potential to give rise to any type of tissue.

An investigation team at Seoul National University, where Hwang once worked, said in late 2005 that Hwang’s team deliberately fabricated vital data in the two papers on human embryonic stem cells.

It did verify, however, that Hwang’s team produced the world’s first cloned dog, an Afghan hound named Snuppy.

“Hwang’s fall discouraged the government from supporting stem cell studies. It also meant that researchers in the field were the objects of scorn,” said Oh Il-hwan, a Catholic University Medical school professor specializing in bioethics.

With major financial backing from his supporters, Hwang went on to form Sooam Biotech Research Foundation in 2006, which specializes in animal cloning and has produced cloned dogs.
