Organ Donation = Shorter Prison Sentence?



There is a move afoot to offer convicts shorter prison sentences in return for a signed organ donor card. Now, I'm an enthusiastic supporter of (posthumous) organ donation. But there's something about the quid pro quo that doesn't sit well with me.

What do you think?


Am I just being lily-livered?

Sphere of Influence




One of the hallmarks of stem cells is that single cells can form spheres under the right conditions: For example, from the breast, they are called "mammospheres".

Last night, I presented my work on cancer stem cells from the retina. One of the attendees came up to me, pointed at my photograph of spheres and said angrily, "Don't call those neurospheres!"


I asked, "Why not?"


Attendee: "Because it doesn't sound right! What does this have to do with the nervous system?!"


I answered, "The retina is part of the central nervous system. It's filled with neurons. I think it's OK to call them neurospheres."


Attendee: "Oh." And she walked away.


OK, you had to be there.

Word Of The Day: Phlyctenule




A phlyctenule is a small whitish bump or blister found on eye. After all of my years working in the field of Ophthalmology, I had never heard of the word until today....

I went to the Ophthalmologist with a "foreign object sensation" in my eye. He found a "phlyctenule". Treatment will be a course of antibiotic drops, 3 times a day, for the next couple of weeks. I will be sans contact lenses until the problem resolves.

Here's looking at you, kid.

Private vs. Federal Funding for Stem Cell Research




This post is for InternetJunkie and the roomie (see last thread).

Stem cell research, as well as other academic biomedical research, is primarily supported by federal funding from the National Institutes of Health (NIH). Legal restrictions prohibit federal funds from being used to create new human embryonic stem cell lines. As a result of this federal ban, many US stem cell researchers are turning to private funding sources in order to carry out their research.

A research lab that receives both federal and private funds needs to build an entirely separate lab with private funding in order to carry out human embryonic stem cell research. They need two microscopes, one bought with federal money for non-stem cell research and the second microscope bought with private foundation money for stem cell work. Everything, incuding lab notebooks, computers, and pens have to be kept separate for human embryonic stem cell work. Consider this duplication of equipment for an entire lab and the cost becomes prohibitive for all but the most well-funded labs.

A lot of innovative research in our country occurs in publicly funded academic labs, where intellectual freedom is given free reign. My own research program has benefited from both federal and private funding. Private funds given to academic labs often mean the difference between survival and ruin. At the same time, private funds often have strings attached, such as how the money can be used (eg. no salary support for personnel, no equipment, etc.). That said, I think there is a place for both public and private funding for biomedical research. Each has its benefits and drawbacks. But I beg to differ with anyone who would suggest that private funding is enough to make up for the lack of public funds for biomedical research, and stem cell research specifically.

Biomedical research in the US has been hurt badly by inadequate funding. The success rate for federal research grants from the National Institute of Health is sinking to below 9% this year. My own NIH grant application scored within the top 14% and was not funded. These federal grants are critical for the success of this research. Are there strings attached to federal money? Sure. Namely, that you are expected to share your discoveries with other academic laboratories in a coopera
tive way, unlike private companies that can keep proprietary secrets for years, only releasing the product when it's a probable money-maker. Meanwhile, if the information had been shared publicly at an earlier state, so much more progress could have been made using that freely-available information.

As a result of the lack of federal research dollars, we see the following:

Labs are being shut down for lack of funds.

Many bright American scientists are leaving the US and moving to countries where they can accomplish their work without so many restrictions.

Other countries, such as Australia, UK, Israel, etc. are getting ahead of us in the stem cell field.

The delay in research, due to lack of adequate funding, leaves many people waiting all that much longer before potential treatments can be made available. How much longer do we keep them waiting?

First Round of Stem Cell Grants in California!




The first CA state stem cell grants are awarded in California! At the site below, you can see Governor Schwarzenegger of CA, scientist Bob Klein and stem cell advocate Don C. Reed at a press conference on CA's recent $40 million to fund embryonic stem cell research, more than NIH provides for embryonic stem cell research for the entire country.

Spitzer shows leadership in stem cell research

By SUSAN SOLOMON
First published: Sunday, February 18, 2007
Gov. Eliot Spitzer's proposed budget includes $100 million to o jump-start stem cell research and other cutting-edge science in New York. This represents a historic first step in what can and should be a concerted effort to make the state a critical center of stem-cell research. The key to this ambitious effort will be embracing an effective private-public partnership. The results could be stunning, both in their clinical implications and their economic impact.
Stem-cell science -- human embryonic stem cell research, in particular -- represents the most important and promising area of scientific endeavor in the effort to help the millions of Americans affected by the worst diseases of our time.

Equally promising is a cutting-edge technique called somatic cell nuclear transfer, in which the DNA of an unfertilized, unimplanted egg is replaced with the genetic material from a donor. The donor's DNA can be obtained, for example, from a simple skin biopsy. If the patient has a particular disease, such as diabetes or Parkinson's, this technique allows for the creation of disease-specific embryonic stem cell lines. These lines could allow scientists to "reverse engineer" diseases and greatly improve our understanding of how they develop and affect the body -- knowledge that is key to developing better treatments and cures.

State money will serve as a tremendous force in moving stem cell science forward far more rapidly, but it will not provide a total solution to the urgent need for funding. Private philanthropy will continue to play a critical role by creating cutting-edge research programs, helping to establish proof of concept and getting them off the ground.

Private funding can be nimble in a way that even the most enlightened government agency cannot. It can be the catalyst, starting programs that can then be scaled up with the benefit of an infusion of government funding. In addition, private funding sources are able to support research programs the government cannot or will not fund.

The combination of public and private dollars focused on the most advanced scientific research has the potential to be enormously powerful. We are poised to create a fertile environment in New York for the world's best scientists and, in the process, provide a significant economic boost to regions in dire need of new industry. Governor Spitzer has planted a flag in the name of scientific and fiscal progress. All New Yorkers affected by disease and disability must show their support for his bold plan.

Right now, there are scientists engaged in human embryonic stem cell research here in New York. They, like their colleagues in places like Boston and San Francisco, have their hands tied by a federal policy that has eliminated government funding for this work, with the exception of research using a few approved stem cell lines that were created using outdated techniques. We are losing a generation of scientists. Young men and women coming out of medical school and doctorate programs have no incentive to pursue stem cell research, despite the fact human embryonic cell research offers the greatest hope for medical advances in our time.

The initial funding proposed by Governor Spitzer -- envisioned as the first element of a larger $2.1 billion state effort to drive stem cell and other innovative research -- sends a clear message to young people here and around the world that advanced scientific research is vital, that we, as a society, believe in it, and that New York is a place where they can forge a career using scientific knowledge for the betterment of humankind.

Gene Therapy Treats Autistic Disease in Mice


There's good news coming out of a British laboratory that studies Rett Syndrome, a severe form of an autistic disease that affects mostly girls:
The study, reported on-line by Science Express today, suggests that the mutant gene, MECP2, can successfully be replaced. Healthy genes were administered to mice bred to be born with the Rett syndrome gene.

Researcher Professor Adrian Bird, of Edinburgh University, Scotland, said: "Like many other people, we expected that giving MeCP2 to mice that were already sick would not work. "The idea that you could put back an essential component after the damage to the brain is done and recover an apparently normal mouse seemed farfetched, as nerve cells that developed in the absence of a key component were assumed to be irrevocably damaged. "The results are gratifyingly clear, though, and must give hope to those who are affected by this distressing disorder."

The four week treatment eradicated tremors, restored breathing to normal and restored mobility and steady gait to the animals.

You Oughta Be In Pictures!




Here's another idea from New Yorkers for the Advancement of Medical Research:

Dear Eyedoc333,

Tell President Bush (and the rest of the world) how you feel about the Stem Cell Research Enhancement Act!
You can be a media star -- and we're going to tell you how, with a little help from our friends at YouTube. Now is your chance to create a short video asking President Bush not to veto the Stem Cell Research Enhancement Act.

If you're a YouTube veteran, you already know how the system works, so go ahead and get started! Dig out your video camera or find a friend who can record you for a minute or two telling President Bush not to veto the Stem Cell Research Enhancement Act.
Here's a sample "script" of what you could say: "Congress -- please pass the Stem Cell Research Enhancement Act. And, this is a message for President Bush -- do the right thing and don't veto the Stem Cell Research Enhancement Act. Nearly three-quarters of Americans support embryonic stem cell research, and you need to do the right thing. I'm an American voter and I'm asking you to sign this bill into law when it lands on your desk. Don't deny us the hope of better treatments and cures."

Here's an example of a video that has already been posted: http://www.youtube.com/watch?v=anrJ5t2-7q4

Please feel free to personalize your video message, if you'd like, but you don't have to give your name or geographic location if that makes you uncomfortable. What's most important is that you say what you think and let your voice be heard.

Stem Cells in New York




It looks like Governor Eliot Spitzer is going ahead with his campaign promise of encouraging stem cell research in New York State. This is significant in light of the anticipated second presidential veto of federal support for stem cell research. Here is the press release that I received from NYAMR (New Yorkers for the Advancement of Medical Research), a group that advocates for stem cell research:

Statewide Coalition of Health Advocacy, Academic and Citizens’ Groups Lauds Spitzer-Paterson Administration on Proposed Funding of Stem-Cell Research

New York, January 31 – New Yorkers for the Advancement of Medical Research (NYAMR) applauds Governor Eliot Spitzer and Lieutenant-Governor David Paterson on their proposal to include significant funding for regenerative medicine, including research involving stem cells, in the Executive Budget for the fiscal year that begins April 1.

“This proposal represents faithful and forthright delivery on an important campaign promise,” said Robin Elliott, Chair of NYAMR and Executive Director of the Parkinson's Disease Foundation. “New Yorkers – all of us, but especially those of us who live with disabling diseases that may benefit from state-sponsored research on stem cells and related issues – are grateful for this, and we congratulate our new leaders.”

As a statewide coalition of 46 health-advocacy groups, academic research centers and citizens’ organizations, NYAMR is committed to ensuring that the Administration’s proposal succeeds in the Legislature and is passed into law, permitting funds to flow to support some of the best ideas in potentially life-saving scientific research.

Stem Cell Controversy at Buffalo Church





It seems that the latest stem cell debate has crossed the line of civil decency in a church:

Political confrontation in Buffalo church for NY lawmaker

Newsday
January 24, 2007, 2:14 PM EST

WASHINGTON (AP) _ Buffalo congressman Brian Higgins walked out of a Catholic church service Sunday after a deacon berated him during a sermon for the lawmaker's recent vote supporting stem cell research. The public tongue-lashing came during morning Mass at St. Thomas Aquinas Catholic church, where deacon Tom McDonnell criticized the Democratic lawmaker. Higgins, who was baptized and married in that church, walked out with his wife and son.

"Leaving was the appropriate thing to do," the two-term lawmaker said Wednesday, adding that he apologized "to the good people of St. Thomas Aquinas for their having been subjected to this whole, unfortunate and avoidable mess... Those people deserved much better."

The pastor of the church, the Rev. Art Smith, offered an apology from the pulpit after the congressman left, the Buffalo News reported in Wednesday's editions. Higgins was criticized by McDonnell for voting earlier this month for a bill that would allow federal funding for research involving stem cell lines derived from surplus embryos created in fertility clinics.

www.newsday.com

Should the deacon publicly point out every "sinner" known to him in the sanctuary of the church? Could he have approached the Congressman privately, away from his family, to express his disappointment about the vote? And then we have this follow-up article from today's Buffalo News:

Anti-abortion group says cleric ‘did his job’

By MARK SOMMER

News Staff Reporter

1/25/2007

The Buffalo Regional Right to Life Committee on Wednesday hailed a deacon who criticized Rep. Brian Higgins during Sunday Mass in St. Thomas Aquinas Catholic Church. Deacon Tom McDonnell’s rebuke of the Buffalo Democrat for voting for federal funding for embryonic stem cell research led Higgins to walk out of the church during his sermon.

“God bless the deacon a thousand times. He did his job. If every bishop, every clergy member of all faiths did their jobs, we wouldn’t have the shedding of innocent life in our country,” said Stacey Vogel of the Buffalo Regional Right to Life Committee. The anti-abortion group’s position was in stark contrast with the phone calls and e-mails at Higgins’ Buffalo and Washington offices, which were running in his favor by a nearly 4 to 1 ratio, according to a staff member.

Higgins said his relationship with St. Thomas Aquinas Church, where he was baptized and married, is “very deep, very meaningful and very long.” He apologized earlier for the congregation’s having to be subjected to criticism of him during the morning Mass. “The lesson here is that the Catholic Church has enough problems and should take greater care before allowing nonpriests to use the church as a forum to advance what clearly was a political agenda,” Higgins said. “I think the letters and e-mails speak for themselves and show the inconsistencies in what the church leaders have said,” he added. One of the callers to his office, Marie Fitzgerald, a 45-year member of St. Thomas Aquinas parish, told The Buffalo News she was appalled by what happened.

“I think it was terrible the way [the Mass] was done. It’s an embarrassment to Brian and to a lot of a parishioners who were there,” Fitzgerald said. She said she held the Rev. Art Smith, the church’s pastor, partly responsible. “I think he’s the boss, and I think he should have put a stop to it,” Fitzgerald said. She also said McDonnell owes the congregation an apology. “I think he should make a public apology to all of us and to Brian in particular,” Fitzgerald said. Vogel said she did not understand why anyone would be rallying to the congressman’s side. “You shouldn’t care so much about Brian’s feelings so much as Brian’s salvation,” Vogel said. She also said the clergy owed McDonnell an apology for any criticism of him for “doing his duty” and said her committee would be giving him an award at its fall dinner.

Polio Success Story




A recent study from the Harvard School of Public Health looked at the economic impact of the first 50 years of polio immunization, from 1955 to 2005. They found that the US has benefited from the polio vaccine, with a net savings of over 180 billion dollars.

The researchers, Professor Thompson and Dr. Radboud Duintjer Tebbens, a research associate at HSPH, estimated the costs and the effectiveness of historical polio vaccination strategies. They found that the U.S. invested over $35 billion between 1955 and 2005 and will continue to invest billions into the future to pay for polio vaccination. They estimated that these historical and future investments translate into over 1.7 billion vaccinations that prevent approximately 1.1 million cases of paralytic polio and over 160,000 deaths, thus saving Americans hundreds of billions of dollars in treatment costs.

One positive impact of this study is that it illustrates the huge economic savings that can come from such a successful public health initiative. Score one for biomedical research!

All Stem Cells, All The Time...





The House passed H.R. 3 today, known as the Stem Cell Research Enhancement Act. Unfortunately, it looks like there are not enough votes to override Bush's veto. Here is a report on today's news from the Houston Chronicle:

The House voted to expand government-financed embryonic stem cell research Thursday, but for the second time in two years lawmakers were unable to muster enough votes to overcome a promised presidential veto. Still, the 253-174 vote was a high watermark in the stem cell debate, drawing advocates closer to the two-thirds vote threshold needed to override President Bush's objections.

With stem cells offering hope for major health care cures, lawmakers on both sides of the issue punctuated the debate with poignant personal stories and clashed over the ethics of the science. Addressing "those who do not have the will to stand up against a presidential veto," freshman Rep. Zach Space, D-Ohio, described his 16-year-old son's battle against juvenile diabetes and wondered aloud what awaited him as an adult. "This research represents the only meaningful hope for a cure in my son's lifetime," Space said.

Embryonic stem cells hold the promise of medical breakthroughs because they have the ability to become any tissue in the body. But the research typically involves the destruction of frozen embryos created for in vitro fertilization, a step that stirs passions over the beginning of life.

Rep. Virginia Foxx, R-N.C., blind in one eye, said she would benefit from stem cell science to replace a detached retina. But she said the federal government should emphasize research into adult stem cells, not those derived from embryos. "Killing human life does not have to be accomplished to create efficacious treatment for people and diseases," she said.

The legislation would lift Bush's 2001 ban on the use of federal dollars spent on deriving new stem cells from fertilized embryos. Bush vetoed similar legislation last year and actor Michael J. Fox elevated the issue into prominence with political ads during last fall's congressional elections. Democrats credit that issue, among others, for helping them drive Republicans from power in Congress.

Update on the Stem Cell Bills




I promised to keep you updated on the status of reintroduction of the stem cell bills. Here is the latest:

From the Coalition for the Advancement of Medical Research (CAMR) :

Dear Eyedoc333,

We wanted to give you an update on House and Senate activity on the Stem Cell Research Enhancement Act in the 110th Congress. On January 5th both chambers convened for business and Members of Congress had an opportunity to introduce legislation for the first time this year. Among the bills introduced were HR 3 and S 5, the House and Senate versions of the Stem Cell Research Enhancement Act. The House has scheduled HR 3 for floor consideration next Thursday 11 January. The Senate will likely take the bill up late this month. The Senate is planning a joint hearing with the Senate Labor-HHS-Ed Appropriations Subcommittee and Senate Health Education Labor and Pensions Committee around the 3rd week in January. Details for that hearing are not yet available.

Given the prompt Congressional action on these bills, your immediate and continued efforts to reach all Members of Congress, especially the new Members, and urge their support for the Stem Cell Research Enhancement Act, are critical.

You can find phone numbers and email addresses for elected officials on Congress.org :

Stem Cell Stocks Rising



With the new stem cell bill coming up in Congress, I find this fascinating:

Shares of biotech companies working on stem cell-related therapies surged Thursday as Democrats in Congress prepared to promote once again legislation that would increase government-funded research in this area.

Link


Ask yourself this--Why is it that biotech stocks are rising despite the fact that the new bill promotes federal funding for stem cell research? Could it be that the new bill would benefit private companies as well? You bet! The National Institutes of Health have funding programs for both academic labs and small businesses. And on top of that, even the larger pharmaceutical companies rely on academic studies, funded by the feds, to assist them with their own research. This new bill is good for business. This is a bill that even corporate America can support.

Get Ready For The New Stem Cell Bill!



From the Coalition for the Advancement of Medical Research:


December 21, 2006

Dear CAMR Members:


First, let me wish you and your family a joyful holiday season and a Happy New Year. Now is the time to look back on the incredible progress that has been made and ready ourselves for important stem cell work in 2007. We all will need to roll up our sleeves in January and get right to work because we have a lot to accomplish in a very short timeframe next year.

In January, the 110th Congress will be sworn into office. The Stem Cell Research Enhancement Act (what we knew as HR 810 for the past two years) will be reintroduced by our Congressional champions in January with identical language and a new bill number. Getting this bipartisan bill passed and enacted has been identified as a top priority by the new leadership in both the Senate and the House of Representatives. A vote on the bill is expected in both chambers in January. That means we need to reach out to everyone we can as soon as possible.

Now is the time for you to use your local contacts and reach out to your new Representatives and Senators before they are even sworn in. Before they come to Washington, DC they need to know that you expect them to vote in favor of the Stem Cell Research Enhancement Act. You will need to be creative, as these new Members might be difficult to locate before January. Perhaps they will be attending local events in your community or opening up a district office. Use every resource you can think of to track them down.
You should also use this time to contact returning Representatives and Senators who may have voted no in the past to convince them now is the time to vote in favor of federal funding for embryonic stem cell research.

The message for all Members of Congress is this:
"Now is the time to pass and enact meaningful stem cell legislation! The Stem Cell Research Enhancement Act will be one of the first bills presented to you for a vote in the 110th Congress and I urge you to vote yes."

You will hear from us as soon as the bill is reintroduced and we will be asking for a huge push in early January to get the word out on the Stem Cell Research Enhancement Act before the votes.


Thank you,
CAMR

Bush's Science Policies: Bad For Our Health




There's a very interesting article in the New Yorker that describes how Bush's regressive science policies, based on religious fundamentalism, have hurt Americans in a multitude of ways. It is a long article, so I'll post an excerpt here--

Vaccinations for contagious diseases like measles and mumps are required before a child can enter public school. That won't be the case with the HPV [cervical cancer] vaccine, however. The Bush Administration, its allies on Capitol Hill, and the religious base of the Republican Party are opposed to mandatory HPV vaccinations. They prefer to rely on education programs that promote abstinence from sexual activity, and see the HPV vaccine as a threat to that policy. For years, conservatives have regarded the human papillomavirus as a kind of index of promiscuity. Many abstinence supporters argue that eliminating the threat of infection would only encourage teen-agers to have sex. "I personally object to vaccinating children when they don't need vaccinations, particularly against a disease that is one hundred per cent preventable with proper sexual behavior,'' Leslee J. Unruh, the founder and president of the Abstinence Clearinghouse, said. "Premarital sex is dangerous, even deadly. Let's not encourage it by vaccinating ten-year-olds so they think they're safe.'' Senator Tom Coburn, Republican of Oklahoma, a family physician and a prominent leader among those who believe that abortion should be illegal, has argued repeatedly in Congress that since condoms can fail, the nation should stop relying on them so heavily. In 2004, he made his position clear when he testified about his experience treating patients who have been infected with HPV: "Studies have indicated for years that promiscuity was associated with cervical cancer.''

Protect the Environmental Protection Agency!




Dear Eyedoc333,


The Environmental Protection Agency (EPA) has begun closing its nationwide network of scientific libraries, effectively preventing EPA scientists and the public from accessing vast amounts of data and information on issues from toxicology to pollution. Several libraries have already been dismantled, with their contents either destroyed or shipped to repositories where they are uncataloged and inaccessible.


The scientific information contained in the EPA libraries is essential to the agency's ability to make fully informed decisions that carry out its mission of protecting human health and the environment. Members of Congress have asked the EPA to cease and desist dismantling these libraries.
Please call EPA Administrator Stephen Johnson at (202) 564-4700 either today or Monday and tell him how much scientists rely on data and literature. Urge him to immediately halt the dismantling of the library system until Congress approves the EPA budget and all materials are readily available online.

Sincerely,

Union of Concerned Scientists
Scientific Integrity Program
