Consumers of canned beef and swine can now stay assured of the quality of the food and relish the taste without any fear of contamination courtesy ‘IdentiGEN’. IdentiGEN has developed TraceBack, the first-ever commercial DNA-fingerprinting technology for meat. The process starts at the farm or slaughterhouse, where animals are given are tested for pathogens. After receiving a clean bill of health, a worker takes a sample of the cow’s blood, meat or hair, analyzes it for genetic identifiers known as single-nucleotide polymorphisms, and stores the information in a central database. Before packaging is done at supermarket, the butchers take another DNA sample and checks it with the database to be sure of a 100% healthy packaged meat. And if there is trace of any errant pathogen found, the source can be traced back within hours thus making it possible for food-safety officials to nail down the source of the outbreak. According to Ronan Loftus, IdentiGEN’s director of business development: Each product has its own inherent label. It’s like nature’s bar code. Once this system is in place, you can pull a package of meat off the shelves and access its entire history. And the consumers have to pay a negligible premium to get 100% healthy meat.

CEO of Biotime’s Comments on Stem Cell Agency and Development of Therapies
Michael West, CEO of Biotime, Inc.of Alameda, Ca., has published the text of his prepared remarks to the Institute of Medicine panel examining the performance of the $3 billion California stem cell agency.
Here is one excerpt from the statement by West, who was also CEO at Advanced Cell Technology and founded Geron.
"To put it simply, stem cell research by itself will not lead to cures. Research and DEVELOPMENT leads to cures. In my opinion, if CIRM fails to deliver on its goal to deliver cures, it will not be a result of internal governance issues. Instead, it will be a result of inefficient capital allocation. A graphic way of visualizing my point is to say that CIRM has historically funded primarily research, and little product development, i.e. large “R” little “d”. Approximately 5% of CIRM’s expenditures have been allocated to biotechnology and health science entities whose expertise is product development, and 95% has been allocated to nonprofit institutions in the state for basic research. Human therapeutic product development in the United States requires a very intense and expensive process for approval that is primarily focused on development side of the equation. In this respect, therapeutic approvals differ significantly from the discovery and development of silicon-based technologies that have been so successfully commercialized in California."

Correction: ACT Not Rejected 15 Times by California Stem Cell Agency
A venture capitalist who said earlier this week that the California stem cell agency rejected 15 grant applications from Advanced Cell Technology this afternoon retracted the statement, which he said was incorrect.
Gregory Bonfiglio, managing partner in Proteus Regenerative Medicine, said in an email,
"Although I believed that number to be true at the time I stated it, I have now determined that the number of CIRM grant applications ACT filed as the principal investigator was substantially below 15."
Bonfiglio made the assertion Tuesday at a meeting of the Institute of Medicine panel looking into the performance of the $3 billion California stem cell agency, which has been criticized for its lack of funding of biotech firms.
Here is more of what Bonfiglio had to say in his email this afternoon,
"Unfortunately, your California Stem Cell Report posting on April 11 contains some inaccurate information, for which I appear to have been the source. As you will recall, I stated during the IOM Panel that Advanced Cell Technology had submitted multiple applications for funding from CIRM, but had been unsuccessful in obtaining any funding from CIRM. I also stated that ACT had been involved in “15 grant applications” to CIRM. You highlighted that number in your April 11 California Stem Cell Report posting. Unfortunately, that number is not accurate. Although I believed that number to be true at the time I stated it, I have now determined that the number of CIRM grant applications ACT filed as the Principal Investigator was substantially below 15. The number I quoted in the IOM Meeting on April 10 included applications in which ACT had some involvement, but was not the lead principal Investigator. ACT has filed several applications for CIRM funding as the lead PI, but the number of CIRM applications in which ACT was the lead PI was far below 15. Moreover, some of ACT’s direct applications for CIRM funding were withdrawn by ACT, rather than denied by CIRM.
"I would request that you correct this inaccuracy regarding ACT's applications for CIRM funding as soon as possible. I'm sure you will agree that the regenerative medicine community, and the general public, have a real and significant interest in obtaining accurate information about developments at CIRM, and that the publication of inaccurate information is a tremendous disservice to all involved. More importantly, ACT is a publicly traded company and the publication of inaccurate information regarding ACT, its technologies, or its funding could have adverse consequences for the company. Furthermore, as an active participant in the regenerative medicine community who has spent his professional career developing a reputation for honesty, accuracy, and integrity I am very concerned that I might be the source of inaccurate information regarding developments within the field of regenerative medicine. For these reasons, I would ask that you retract the statement in your April 11 Blog posting that ACT was 'rejected 15 times for funding' by CIRM, and that you refrain from making any other statements to that effect.
"I appreciate your cooperation in this regard, and I would request that you move quickly to correct the inaccuracy in your April 11 Blog posting. As I am sure you are aware, information in blog postings is sometimes picked up by more traditional media, and I would not want any republication of this inaccurate information regarding ACT’s grant applications to CIRM."
At the time Bonfiglio made his comments concerning ACT, top officials of the stem cell agency were in the room, but did not make any statement concerning his assertion. On the morning of April 11 prior to publication of the item, the California Stem Cell Report asked ACT for comment .
No response has been received from ACT about the figure. CIRM also has not commented since the item appeared.

California Stem Cell Agency Cited for Improvements in Transparency
IRVINE, Ca. – The $3 billion California stem cell agency was praised this week for making progress in accountability and transparency during the last year.
The comments came from a representative of California state Controlller John Chiang, the state's top fiscal officer and who also chairs the only state entity specifically charged with financial oversight of the stem cell agency and its board.
Ruth Holton-Hodson, deputy state controller, told the blue-ribbon Institute of Medicine panel examining the performance of the stem cell agency that the controller's office "would like to acknowledge the progress the new leadership has made in the last year towards making CIRM a far more transparent and accountable agency than it has been in the past."
CIRM has a new chairman, J.T. Thomas, a Los Angeles financier, who has been in place since the beginning of last July. He succeeded Bob Klein, who was the initial agency chairman and who took office in 2004.
In her testimony at the IOM hearing here on Tuesday, Holton-Hodson discussed previous problems that CIRM had with the transparency of its budget. She said,
"We are very pleased that CIRM’s new leadership recognized this as a problem and quickly adopted a much more transparent budget format which is broken down by function. To make CIRM’s expenditures as transparent as possible, we have also recommended that they post the annual budget on the website. Again, we’re pleased to say that the new leadership has agreed to do this."
She also said,
"At our most recent meeting (of the Citizens Financial Accountability and Oversight Committee), we also recommended that CIRM post all of its private donations and they have agreed to do this."
Holton-Hodson criticized the dual executive arrangement at CIRM that is written into law by Proposition 71. She said,
"It is difficult to uphold the appearance of accountability and objectivity when the board chair has direct line authority over some CIRM staff positions. In essence under the current model, the chair is responsible for evaluating and approving some of the work of the chair.
"While this issue is still outstanding, it is important to acknowledge that the current leadership has made significant progress in more clearly delineating the responsibilities of the chair and the president."

California Stem Cell Agency Nixes ACT Grant Applications 15 Times
(Editor's note: The assertion in this item that 15 applications by ACT were rejected by the California stem cell agency is incorrect, according to the venture capitalist who made the statement. He retracted it on the afternoon of April 12. His explanation can be found here. )
IRVINE, Ca. --The only firm in the nation conducting an ongoing hESC clinical trial has been rejected 15 times for funding by California's $3 billion stem cell agency.
The figure was reported yesterday at a hearing by the blue-ribbon Institute of Medicine panel looking into the performance of the stem cell agency, which has been sharply criticized in recent years for its paucity of industry funding.
Gregory Bonfiglio, managing partner in Proteus Regenerative Medicine, a stem cell venture capital firm in Portola Valley, Ca., disclosed the grant attempts by Advanced Cell Technology, whose nominal headquarters are in Santa Monica, Ca. Bonfiglio indicated that it was a high profile example of how CIRM is not taking the necessary steps to fulfill its goal of developing therapies that actually reach the clinic.
He noted that ACT received national attention in January when it posted favorable findings for its clinical trial at UCLA dealing with blindness but that the firm was still unable to win a CIRM grant over the last several years.
ACT had moved much of its operations to California in the wake of passage of Proposition 71, the measure that created the state's stem cell research effort in 2004. It has since re-centered its operations in Massachusetts.
The California Stem Cell Report has queried ACT on its grant efforts and will carry its response verbatim when it is received.
Another firm, which cannot be identified, said privately yesterday that it was rejected 14 times.
According to our calculations based on figures this morning on the CIRM web site, businesses have received only $54.3 million in grants and loans during the last seven years, 4 percent of the $1.3 billion awarded. However, the CIRM list slightly understates the industry total. At least two other firms are sharing in two $20 million grants involving academic institutions, but are not noted on the list.
Yesterday's IOM meeting was the second and final California public session for the CIRM inquiry. Most of the day was occupied by a variety of critiques of the organization. The panel has already heard extensively from the agency itself and beneficiaries of its grants. The IOM report is expected in November.
Harold Shapiro, chairman of the panel and former president of Princeton University, described yesterday afternoon's panel involving stem cell business executives as "one of the more interesting" of the day.
One of the speakers was Michael West, CEO of Biotime in Alameda, which has received $4.7 million from CIRM. West, the founder of Geron, was also head of ACT when it moved it to California. He said CIRM had several "blind spots," including misconceptions about how products are made. For example, West said, CIRM's performance indicates that it does not fully understand that development leads directly to cures -- not research.
West said that if the high tech industry had to rely on CIRM-type funding years ago, laptops and iPads would still be in the lab instead of the marketplace.
The business industry representatives said that creation of CIRM has been beneficial for stem cell research, but cited a number of deficiencies in connection with industry applications.
In some ways, their comments echoed past remarks by several CIRM board members, who have expressed concern about the lack of funding for industry, as well as those of the agency's own external review panel. One issue raised by those CIRM directors has been the lack of grant reviewers with product development and industry expertise.
At yesterday's hearing, Gabriel Nistor, vice president of research and development at California Stem Cell in Irvine, said, it is "exceedingly rare to find academics (grant reviewers) that understand the complexities" involving industry. Nistor said his firm has applied for a "few" CIRM grants. None have been awarded.
Also speaking was Allan Robins, CEO of Viacyte in San Diego, who said his firm has done well with CIRM funding. It has received $26.2 million, nearly all of it in the form of a loan. But he said companies develop products – not academia.

The Search for Stem Cell Cures: Can California’s $3 Billion Agency Move Audaciously?
IRVINE, Ca.-- California's unprecedented stem cell research effort faces a tight timetable for making major progress in fulfilling promises to voters seven years ago, complicated by potential conflicts of interest, a blue-ribbon panel was told this morning.
David Jensen, editor of the California Stem Cell Report, made the comments to the Institute of Medicine panel looking into the performance of the $3 billion California Institute of Regenerative Medicine.
The panel's inquiry comes as the agency is re-evaluating its strategies as it faces loss of funding in about 2017.
Here is the full text of Jensen's statement.

Center for Genetics and Society: 'Wrong' to Ask for More Billions for Stem Cell Agency
IRVINE, Ca. – The Center for Genetics and Society today said it would "wrong" to ask the people of California for more money to continue financing stem cell research at state expense.
Marcy Darnovsky, associate executive director of the Berkeley, Ca., non-profit group, addressed a blue-ribbon Institute of Medicine panel evaluating the performance of the $3 billion California stem cell agency, which is financed by money borrowed by the state. The agency is expected to run out of cash in about five years.
Darnovsky said,
"In structural terms, a key question now is what will happen after CIRM’s public funding is exhausted. According to CIRM’s transition plan, another bond measure for additional public funding 'would be premature at this time,' but is still on the table. In our view, any additional public monies for CIRM would have to be justified in an analysis that emphasized health care priorities and health care disparities. While there is always tension between the allocation of public funds to scientific research and to other public goods, given our state’s economic decline and budgetary crisis, with so many critical social programs being gutted, we believe it would be simply wrong to ask Californians to set aside more money for one avenue of research, however important."
Representatives of the stem cell agency were present at today's hearing on the UC Irvine campus, but did not speak publicly at today's session. CIRM officials, however, have testified before the panel on two other days of public hearings. The agency is paying the IOM $700,000 to conduct the study. Its results and recommendations are expected to be published in November.
Darnovsky and others testifying at the morning session were critical of the agency's lack of accountability, built-in conflicts of interest and immunity from normal government oversight (see here and here).
Darnovsky said, "
The requirement for 70% super-majorities (to change the law regarding CIRM) means that there is still no meaningful oversight of CIRM by elected officials. The ICOC is still tainted by its built-in conflicts of interest. It still includes no representation of the public beyond disease advocates. Members of CIRM’s powerful Working Groups, including the one that reviews grant applications, are still not required to publicly disclose their individual financial interests.
"Given that hundreds of millions of dollars remain to be disbursed, and the widely mooted possibility that CIRM will develop a role that continues beyond the public funding stream that was allocated in 2004, now is the time to clarify and address these issues."
Here is the full text of Darnovsky's comments.

Consumer Watchdog Says ‘Serious Consideration’ Needed on Continued Cash for State Stem Cell Agency
IRVINE, Ca. – The Consumer Watchdog organization says that serious consideration should be given to whether the state should halt borrowing money to finance the $3 billion California stem cell agency.
The statement was prepared for delivery tomorrow here to a blue-ribbon Institute of Medicine panel evaluating the performance of the research effort, which was created by a ballot initiative in 2004. The agency's only real source of cash is bonds issued by the state, which means the agency will cost $6 billion including interest by end of its grant-making life in about 2017.
John M. Simpson, stem cell project director for Consumer Watchdog of Santa Monica, Ca., said that the political and scientific environment has changed substantially since 2004. The Bush Administration had restricted federal funding of hESC research then, causing an uproar in the scientific community. Funding has since been restored.
Simpson said the stem cell measure "made sense" seven years ago. He said the stem cell agency and its governing board "must recognize that the political, scientific and economic environment have dramatically altered since the passage of Proposition 71."
His statement continued,
"It is also appropriate to consider seriously whether issuing all $3 billion in authorized bonds is the correct policy in light of the new environment and economic realties facing the state."
Simpson was invited make his statement to the IOM panel, which is midway through its public process of looking into CIRM's operations. It is doing so at the behest of CIRM, which is paying the prestigious organization $700,000 to perform the work.
Simpson also made a number of recommendations for changes at CIRM, many of which would require a change in state law or passage of another ballot measure. Proposition 71, which created CIRM and altered the state Constitution, requires a super, super-majority vote (70 percent) by the legislature to make changes at CIRM.
The Consumer Watchdog proposals (full text below) include reducing the size of the 29-member board to 15, including public members on the board, reducing the super-majority requirement on board quorums to a majority, eliminating the controversial dual executive arrangement at CIRM, conducting grant reviews in public and publicly disclosing the financial interests of reviewers.Consumer Watchdog Statement to IOM-CIRM Panel April 9, 2012

iPad App for Education of Heart Patients After Surgery – Mayo Clinic Video
From Mayo Clinic YouTube channel: "Being in the hospital after major surgery is no fun. On top of dealing with pain, patients have uncertainty. They also have to worry about getting all the information they need to support their recovery. That's not always easy in the hospital; things happen quickly and doctors and hospital staff are often really busy. Doctors at Mayo Clinic may have a solution to this issue. They're giving iPads to heart surgery patients to see if a new iPad app can make hospital stays easier and more satisfying."
Our research presented during the 2011 ACAAI meeting showed that 95% patients thought the iPad was helpful for coming to understanding of their condition:
PATIENT PERCEPTION OF A POINT-OF-CARE TABLET COMPUTER (IPAD™) BEING USED FOR PATIENT EDUCATION - P318
A. Nickels*, V. Dimov, V. Press, R.Wolf, Chicago, IL.
Background:
During the fall of 2010, the Internal Medicine/Pediatrics program at University of Chicago introduced Point-of-Care Tablet Computers (iPad™) for clinical use. iPads™ are intended to improve access to EMR, work flow, resident and patient education, and access to electronic clinical tools. The graphic display and ease of interface makes the iPad™ a potentially powerful tool to achieve these goals. This pilot study is designed to gauge the initial patient perception of the iPad™ when used for patient education.
Methods:
8 questions, physician administered, patient survey of Allergy Immunology patients or their parents. Preloaded iPads™ with education materials (“mind map” diagrams, clinical pictures) into the photo software were used to clinically education the patients. Simple percentages and Fisher’s exact non-parametric test were used for statistical analysis. Results: 20 patients surveyed (11 resident/9 attending). For those survey items without 100% agreement, there was no statistically significant difference in responses based on level of training (p?0.45). 100% [0.861, 1] of participants liked the iPad™ being used to help explain their children’s condition, 95% [0.783, 0.997] of participants did not find it distracting. 100% [0.8601, 1] found it helpful. 100% [0.861, 1] would like it to be used again to help explain medical information. 95% [0.784, 0.9974386] thought the iPad™ was helpful for coming to understanding of their condition. Limitations of this study include a convenient sample, physician-administered survey, and observer bias.
Conclusion:
Patient perception was very positive toward the use of a Point-of-Care Tablet Computer (iPad™) in a clinical setting. While limited to only two operators, level of training did not have an effect on patient perception. Confirmation of the results may be required before wider implementation.

Will traditional scientific journals follow newspapers into oblivion, asks former BMJ editor
Richard Smith is a former editor of the BMJ and chief executive of the BMJ Publishing Group. He is well-known for provocative editorials. Here is an excerpt from one, published recently in The Scientist:
"Elsevier, the world’s largest publisher of scientific journals, has seen broadly stable revenues (€2,236 million in 2006, €2,370 million in 2010) but growing profits (€683 million in 2006, €847 million in 2010).
Scientific journals remain very profitable. Few industries manage a profit margin of 35.7% (that for Elsevier in 2010), but then few industries are given their raw material—in this case, scientific studies—not only for free, but also in a form that needs minimal processing."
It is nice to see that the current and a former editor of the two most famous British medical journals, The Lancet and BMJ, are now on Twitter:

87% of people older than 50 took one or more drug, according to Australian survey
A postal survey included a random sample of 4,500 Australians aged ? 50 years between in 2009-2010 and the response rate was 37%.
Medications use was very common, 87% of participants took one or more drug (called medicines in Australia) and 43% took five or more in the previous 24 hours.
Complementary medicines were used by 46% of participants.
The most commonly used medications were:
- antihypertensive agents, 43% of participants
- natural marine and animal products including fish oil and glucosamine, 32%
- lipid-lowering agents, 30%
Doctors recommended 79% of all medications and 93% of conventional medications.
Much medicines use was to prevent future disease by influencing risk factors.
In a 2011 study, 4 medication classes were linked to 67% of drug-related hospitalizations:
- warfarin, 33%
- insulins, 14%
- oral antiplatelet agents, 13%
- oral hypoglycemic agents, 11%
High-risk medications were implicated in only 1.2% of hospitalizations.
50% of these hospitalizations were among adults 80 years of age or older. 65% of hospitalizations were due to unintentional overdoses.
Classification of adverse reactions to drugs: "SOAP III" mnemonic (click to enlarge the image):
Adverse drug reactions (ADRs) affect 10–20% of hospitalized patients and 25% of outpatients.
Rule of 10s in ADR:
10% of patients develop ADR
10% of these are due to allergy
10% of these lead to anaphylaxis
10% of these lead to death

"Wonder drug" dogs are the only animals that look at right side of human face where emotions are expressed
People who have dogs as pets are much less likely to have a heart attack. If they do have a heart attack, they are 2-3 times more likely to survive it.
Mitochondrial genetics studies have shown conclusively that dogs have descended from wolves. Dogs' genes are 99.8% the same as the wolf genes, yet dogs behave in a fundamentally different way.
Over more than 100,000 years dogs have evolved to recognize human emotions. It has been a collaborative process all along. Humans are able to recognize 6 types of dog barks expressing emotions and "intentions" such as fear, excitement, aggression and so on. Dogs are the only animals that specifically look at the right side of the human face where emotions are expressed (see the NOVA video and website below).
Dogs follow directions while chimpanzees, the apes evolutionary closest to humans, do not. The smartest dog can learn 300 different words which is the vocabulary size of a 2-year-old child.
The "400 mnemonic":
400 million dogs worldwide
400 breeds of dogs have been developed by humans
According to a Cleveland Clinic psychologist, "dogs could be called wonder drugs":
"Dogs can provide people with many things. Protection, friendship, and unconditional love top the list, but they may also provide health benefits, too."

The Mollusc Matrix 2: shell-shock
First it was the snails, now it’s the turn of the clams to be plugged in and used as living batteries. The same group of scientists from the US and Israel, led by Evgeny Katz, has now implanted biofuel cells into clams and integrated them into batteries.
The researchers implanted the battery’s electrodes in the clam through holes cut into their shells. To produce power, enzymes on the electrodes catalyse the oxidation of glucose, which the clams produce when they metabolise food.
Katz’s team even set up the clams in series and parallel and tested their power outputs, comparing the two arrangements. Three clams set up in series produced a measly 5.2µW; three clams in parallel generated a massive 37µW.
They hooked up the clams to a capacitor to collect the energy for an hour and then discharged it through an electrical motor and managed to make the motor rotate a quarter of a full turn. The team says this is the first step on the long journey to bioelectronic self-powered cyborgs for potential military and homeland security applications. Self-powered cybernetic organisms? Now I can’t get the image of a Terminator clam brandishing an Uzi 9mm out of my head!
Hasta la vista, baby!

Lizzie in the sky with diamonds
Here at the Chemistry World homestead we’re coming over all patriotic with the diamond jubilee of the Queen this year. So the news that the chaps responsible for the wonderful periodic table of videos have engraved the world’s smallest portrait of the Queen onto a diamond to celebrate the jubilee brought a tear to my eye.
The periodic videos team at the University of Nottingham dug out the diamond to be engraved from an old, broken infrared spectroscopy mount. They then had a quick word with some colleagues in the nanotechnology department and borrowed their engraving device to fire high speed gallium ions at the diamond to etch out the portrait. Using the picture of the Queen found on a stamp they produced a portrait just 46µm by 32µm – you could get 300,000 of these onto a postage stamp.
Martyn Poliakoff, a professor of chemistry at Nottingham and the presenter of the periodic table of videos, says that they’ve thought about giving the portrait to the Queen to celebrate the jubilee but aren’t sure what she’d do with it. They now considering donating it to an exhibition of some kind. If you have any ideas about a home for the diamond portrait they’d like to hear from you.

Chemistry in its element – ozone

The late Sherwood Rowland got his Nobel prize for his work on this week’s molecule. But it’s best kept at a safe distance. David Lindsay takes a look at ozone in this week’s Chemistry in its element podcast to find out why.
