Genetic Link For Bipolar

Clip Source: psychcentral.com

Monday, Aug 18 (Psych Central) -- The largest genetic analysis of its kind suggests bipolar disorder is influenced by the balance of sodium and calcium in brain cells.

Researchers found an association between the disorder and variation in two genes that make components of channels that manage the flow of the elements into and out of cells, including neurons.

“A neuron’s excitability – whether it will fire – hinges on this delicate equilibrium,”

“Finding statistically robust associations linked to two proteins that may be involved in regulating such ion channels – and that are also thought to be targets of drugs used to clinically to treat bipolar disorder – is astonishing.”

Although it’s not yet known if or how the suspect genetic variation might affect the balance machinery, the results point to the possibility that bipolar disorder might stem, at least in part, from malfunction of ion channels.

clipper's remarks: Joan Brugge, Chair of the Department of Cell Biology at Harvard Medical School, said the new study "provides exciting new insights into yet another aspect of cell plasticity that was not appreciated previously and that offers great potential therapeutically. Direct reprogramming represents a more straight-forward strategy to treat diseases involving loss of function of specific cell populations than approaches requiring an intermediate embryonic stem cell," she said.

In a feat of biological prestidigitation likely to turn the field of regenerative medicine on its head, Harvard Stem Cell Institute (HSCI) co-director Doug Melton and post doctoral fellow Qiao "Joe" Zhou report having achieved what has long been a dream and ultimate goal of developmental biologists – directly turning one type of fully formed adult cell into another type of adult cell.

The Melton team reports in today's online edition of the journal Nature that, using a technique it is calling "direct reprogramming," the team is able to turn mouse exocrine cells, which make up about 95 percent of the pancreas, into precious and rare insulin-producing beta cells. These beta cells, which comrpise about one percent of the pancreas, are the cells that die off in Type I diabetes.

In addition to its value for the field of regenerative medicine, the work also is a major step forward toward eventually developing a treatment for Type II – and eventually Type I – diabetes

Stem cells 'created from teeth'

Many religious groups object to using embryos for medical research

Japanese scientists say they have created human stem cells from tissue taken from the discarded wisdom teeth of a 10-year-old girl.

The researchers say their work suggests that wisdom teeth could be a suitable alternative to human embryos as a source for therapeutic stem cells.

Research involving stem cells is seen as having the potential to treat many life-threatening diseases.

But some people believe using human embryos is ethically controversial.

The researchers, based at the National Institute of Advanced Industrial Science and Technology (AIST), say it will be at least five years before their findings result in practical medical applications.

Stem cells have the ability to develop into other kinds of human cells, and experts believe they may eventually lead to treatments for some of the most intractable conditions, such as cancer and diabetes.

Stem cells could allow 'blood farms'

Wed, 20 Aug 2008 23:45:44 GMT

clipper's remarks: One of the issues recently has been the shelf life of blood, where the rotation principle-first in first out can leave blood 'stale' and unsafe. There is also the fact that the contributions cannot meet the demand, and the increase in surgery that requires large volumes of blood. Transplant, and heart surgery being prime examples. They have been searching for a means of producing blood artificially, but the prospect of using stem cells, makes it more likely to be a reality.
One of the most important aspects is that the red cells have no nucleus, so no nucleic DNA.
A fact that can relieve many ethical, and practical problems.

Embryonic stem cells can be used to grow vats of red blood cells, which could lead to the creation of 'farms' that could provide limitless sources of blood, US researchers report.

The research by scientists from Advanced Cell Technology, the University of Illinois at Chicago and the Mayo Clinic in Rochester appears in the journal Blood.

"I think it's really a big break for us," says Dr Robert Lanza from Advanced Cell Technology.

Stem cells are the body's master cells, replenishing various cells and tissues as they die. Stem cells taken from days-old embryos are especially powerful, with the ability to produce any cell type.

Doctors hope to someday use them to provide tailor-made transplants for patients, and to study disease. One problem is that the immune system may reject tissues grown from someone else's stem cells.

Red blood cells may be an exception to this, because they do not have a nucleus.

"You don't have to worry about the DNA going haywire," says Lanza.

Scientists Create Blood From Stem Cells

Another phenomenally beneficial step forward for us; let's hope religion doesn't raise its ugly head yet again to stand in the way of scientific progress as so frequently does.

There will be people, such as myself, who will refuse to be treated with such blood because it comes from the destruction of embryos.

Thanks, Paul - more blood for us.

How can you support profiting from killing someone else no matter how much good you take out of it?

There is no doubt that stopping the life of an embryo is killing because it is alive

Waaaah wahhhh! The poor embryo that will more than likely be incinerated eventually anyways. Yes, I will admit that these frozen embryos could eventually be implanted in someone's womb. But I would venture a guess that there is a larger supply of frozen embryos than there is demand for implantation.

I hope Glod and Cheesus save you all from their wrath.

Human Dignity and the Sanctity of Life

For this reason, John McCain opposes the intentional creation of human embryos for research purposes. To that end, Senator McCain voted to ban the practice of "fetal farming," making it a federal crime for researchers to use cells or fetal tissue from an embryo created for research purposes. Furthermore, he voted to ban attempts to use or obtain human cells gestated in animals. Finally, John McCain strongly opposes human cloning and voted to ban the practice, and any related experimentation, under federal law.

Stem cell research offers tremendous hope for those suffering from a variety of deadly diseases - hope for both cures and life-extending treatments. However, the compassion to relieve suffering and to cure deadly disease cannot erode moral and ethical principles.

Political Interference of the Surgeon General (No way!)

Mon, 11 Aug 2008 17:16:45 GMT

clipper's remarks: Surely they are lying! There is no way they controlled free speech! I am astonished that they would even suggest such things!

Like this: On the increasing politicization of the Surgeon General's position:

-Previous Surgeon Generals agreed that: "never had they seen Washington, D.C. so partisan or a new Surgeon General so politically challenged and marginalized as during my tenure."

-"[T]he reality is that the nation's doctor [i.e.- the Surgeon General] has been marginalized and relegated to a position with no independent budget, and with supervisors who are political appointees with partisan agendas. Anything that doesn't fit into the political appointees' ideological, theological, or political agenda is ignored, marginalized, or simply buried."

- "Politicians in the late 1960s decided that the Office of the Surgeon General should be disempowered and its authorities placed within offices of Department of Health and Human Services political appointees."

Just days prior to the confirmation hearing of Dr. James Holsinger, Bush's controversial nominee for Surgeon General, the current and two former Surgeon Generals testified about political interference of that office

At a hearing before the House Committee on Oversight and Government Reform, Surgeon General Dr. Richard Carmona testified that the Bush administration would not allow him to speak or issue reports about stem cells, emergency contraception, sex education, or prison mental and global health issues

But the Bush administration didn't just try to stifle Carmona's speech, it also dictated it. For example, Carmona testified that he was never able to get approval for a report on global health because it did not contain enough positive reference to the Bush administration and that he was ordered to mention President Bush's name three times on every page of his speeches

Qld scientists claim stem cells breakthrough

Queensland scientists say a breakthrough in embryonic stem cell research could help grow more organs for transplant.

Researchers at the Queensland University of Technology (QUT) in Brisbane have discovered a way to grow human embryonic stem cells using synthetic proteins.

QUT spokesman Dr David Leavesley says the artificial proteins are cheaper and more efficient.

"The real breakthrough here is that we're no longer required to use animal products, which sometimes contain viruses that we can't detect," he said.

"Now we can absolutely control the conditions that they grow in and with fewer components, they're cheaper to produce.

"However, it doesn't remove the moral dilemma of using embryos to obtain these stem cells."
