Stem cell therapy for 13-year-old dog helps with its arthritis

Posted on March 28, 2012 by ev1

COLUMBIA, SC (WIS) - A few weeks ago, we told you the story of Maggie, the 13-year-old Boykin Spaniel who was suffering from arthritis.

Maggie is enjoying life once again thanks to a new type of surgery. The dog received stem cell therapy surgery six weeks ago.

Doctors were able to use adult stem cells from Maggie's blood and fat samples to collect repair cells. They then took the cells and repaired the dog's arthritic spine.

Maggie's owner, Beth Phibbs, says she could tell the dog had been in pain.

"You could tell she didn't feel well, but yet now she is like she's 5 and she's 13. She just runs out and she plays. I think she knows. She can feel the difference," Phibbs said.

The surgery costs about $2,000, but Medi-vet America says this costs about half as much as the older treatments.

Practical Nutrition: Juice cleanses

Posted on March 28, 2012 by ev1

There is something about drinking a glass of juice that makes us feel so virtuous. Perhaps it's because we feel as if we're doing something healthful when we don't take time to eat a balanced diet.

I've had clients switch from 20 ounces of soda to the same amount of juice, thinking it's healthier. But a 20-ounce serving of 100 percent orange juice has 275 calories; the same amount of Coca-Cola has 240.

At least with juice you get some potassium, vitamin C and folic acid that you miss with soda. But that's an expensive calorie price to pay when a medium orange has those nutrients for about 80 calories.

Juicing, or juice cleanses, has surged in popularity again, especially with Hollywood stars promoting it. The programs give the impression that we don't get enough nutrients from the foods we eat, or that toxins build up in our bodies.

We tend to forget that we have a liver and kidneys and their jobs are to filter our blood and rid our body of waste and any potential toxins.

Currently, no medical evidence or clinical studies support the benefits of juice cleanses, or that fruit and vegetables as juice are superior to solid forms.

One popular plan offers five fruit and vegetable juice products for a variety of cleanses. Products vary from 110 to 300 calories per 16-ounce bottle, aiming for 900 to 1,100 calories per daily cleanse.

Some weight loss should occur at that calorie level, but it will be regained if a person returns to undesirable eating habits.

Juicing for a short time or for one daily meal shouldn't cause problems for healthy people. But some people should avoid juicing. Pregnant and breastfeeding women have higher nutritional needs that cannot be met by juice alone.

Cell Therapy Improves Damaged Heart In Study

Posted on March 28, 2012 by ev1

March 27, 2012

According to a new study, using a patients own bone marrow may help repair damaged areas of the heart caused by heart failure.

Researchers found that left ventricular ejection fraction increased by 2.7 percent in patients who received stem cell therapy.

The study, which was presented at the American College of Cardiologys 61st Annual Scientific Session, revealed that the improvement in ejection fraction correlated with the number of CD34+ and CD133+ cells in the bone marrow.

This is the kind of information we need in order to move forward with the clinical use of stem cell therapy, Emerson Perin, MD, PhD, director of clinical research for cardiovascular medicine at the Texas Heart Institute and the studys lead investigator, said at the event.

The study included 92 patients who were randomly selected to receive stem cell treatment or placebo. The patients all had chronic ischemic heart disease and an ejection fraction of less than 45 percent along with heart failure.

Doctors placed a catheter in the hearts left ventricle to inject 3 ccs, or 100 million stem cells, into an average of 15 sites of the stem cell patients hearts.

The doctors used electromechanical mapping of the heart to measure the voltage in areas of the heart muscle and create a real-time image of the heart.

With this mapping procedure, we have a roadmap to the heart muscle, said Dr. Perin. Were very careful about where we inject the cells; electromechanical mapping allows us to target the cell injections to viable areas of the heart.

The trial was designed to determine whether left ventricular end systolic volume and myocardial oxygen consumption improved in patients who received stem cell treatment.

Accused drunken driver blows ‘amazing’ .384

Posted on March 28, 2012 by ev1

A Brockton man defied common physiology when Rhode Island state troopers say they caught him driving with a blood-alcohol level of .384, nearly five times the Bay States legal driving limit and amazingly, the second highest a veteran trooper has seen in his decades-long career.

The amazing thing is, his blood alcohol level was that high and he was coherent and awake, Rhode Island State Police Capt. Frank B. Castellone said of Dammon McLaren, 32. It was pretty scary to think he was driving a car.

McLaren was unsteady on his feet, slurred his speech and reeked of alcohol when police pulled over his car in Providence early Sunday, according to state police. After submitting to a Breathalyzer, McLaren blew a .373, then a .384, police said levels Castellone said are only topped by a 2008 drunk driver who registered a .49 when Rhode Island state police stopped him.

Its the second highest Ive ever seen in 22 years, Castellone said.

State police said a person normally passes out by the time he or she hits .30, and levels approaching .40 can put a person in danger of a coma and even death due to respiratory arrest.

McLaren, since released, is due back in Providence court on April 6, Castellone said. He is facing charges of driving with BAC of 0.15 or greater, and was issued a traffic summons for a laned roadway violation, not using a turn signal and operating with an expired registration.

This behavior will not be tolerated on the highways of our state, Col. Steven G. ODonnell, Superintendent of the Rhode Island State Police, said in a statement. We will use all resources available to the Division, including overtime patrols using low profile vehicles, to remain vigilant and curb this activity.

Ottawa, Canada (March 27, 2012) In response to an urgent call from public health, health care, child care, and fitness practitioners, the Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, has developed two important sets of guidelines directed at improving the health and activity levels of infants and toddlers. The Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years) and the Canadian Physical Activity Guidelines for the Early Years (aged 0-4 years) are presented in the April 2012 issue of the journal Applied Physiology, Nutrition, and Metabolism (APNM).

"The development and publication of the first evidence-informed guidelines for the early years represents an important public health advancement in Canada," says Mark Tremblay, Director of Healthy Active Living and Obesity Research (HALO) at the Children's Hospital of Eastern Ontario (CHEO) Research Institute, Chair of the CSEP Guidelines Steering Committee and lead author of the published papers. "The guidelines are based on the best available evidence, input from researchers, clinicians and care-providers and harmonized with international initiatives."

"As leaders in physical activity, we aim to increase the Canadian public's awareness, adoption and implementation of the new Guidelines for the Early Years," says Earl Noble, President of CSEP. "We've worked with numerous partners, including the HALO Research Group, to develop these Guidelines. CSEP is proud to provide this scientific-based guidance to assist promoting physical activity and discouraging sedentary behaviours in young Canadians."

Caregivers are advised to minimize the time infants, toddlers and preschoolers spend during waking hours sitting or being restrained (e.g., stroller, high chair). For those under 2 years, screen time (e.g., TV, computer, electronic games) is to be avoided. For children 2-4 years, screen time should be limited to less than one hour per day, and less is better. The guidelines for physical activity recommend that infants should be active several times daily through interactive floorbased play. Toddlers and preschoolers should accumulate at least 180 minutes of physical activity throughout the day.

More activity, they advise, provides greater benefits.

"Research on Canadian school-aged children has shown that obesity is rampant, physical fitness is declining, and activity levels are at an all time low. The time for early intervention has arrived," says Terry Graham, Editor, APNM. "These new Guidelines are an essential foundation for the health and ongoing development of our children."

The Guidelines for the Early Years (aged 0-4 years) are presented in French and English in the journal APNM at http://www.nrcresearchpress.com/apnm

AMP optimistic in suit to invalidate patents on breast cancer genes

Posted on March 28, 2012 by ev1

Bethesda, MD -- Now that the Supreme Court has remanded Association for Molecular Pathology et al. v. Myriad Genetics, Inc., et al. (AMP v. Myriad) to the Court of Appeals for the Federal Circuit for further consideration, AMP is optimistic that it will ultimately prevail in its lawsuit to invalidate patents on two genes that are known to cause breast cancer.

"Our members have witnessed the adverse effects of gene patents on patient care," stated Iris Schrijver, AMP President. "By awarding monopolies in testing of patented genes, these patents reduce patient access to genetic tests, increase test prices, and stand in the way of innovations in diagnostic methods." Further, Dr. Schrijver added, "Because variation in gene sequences plays an important role in the development and progression of many diseases, through gene patents patent holders can essentially gain ownership of the understanding of some diseases and of certain areas of patient care itself."

Stated Roger D. Klein, MD, JD, Chair of the AMP Professional Relations Committee: "We were extremely encouraged by the Supreme Court's reaffirmation in its Prometheus decision of the longstanding principle that natural phenomena are not patent eligible. In Prometheus, the Supreme Court clearly ruled that the correlation between a biomarker and a clinical phenotype cannot be patented. Similarly, in light of this decision we expect that the Court of Appeals for the Federal Circuit will ultimately find that patents on natural products, in this case BRCA1 and BRCA2, cannot be used to exclude physicians and others from examining their patient's genes for disease-related variants."

In its original decision, the Appeals Court held that human gene sequences are patentable subject matter when separated from their native state within cells. This is really a 'form versus substance' argument, said Mary Williams, AMP Executive Director. "A disease-causing mutation means the same thing for the patient irrespective of whether a gene is examined inside or outside the patient's body."

"AMP is looking forward to the proceedings in the lower court. We are confident that optimal patient care and sound science will ultimately prevail," stated Williams.

Nutrition: That's not ice cream… it's 'pink slime'

Posted on March 28, 2012 by ev1

Take a cow. Chop it into pieces. Sell the edible bits to supermarkets, ship its hide to a handbag factory, send leftover bones and organs to a rendering plant. Now, what's left? In most of the developed world, the answer is simple: pet food. The sinew, gristle and fat regarded as unfit for human consumption are taken away by Mr Pedigree Chum and turned into something the salmonella-resistant stomach of your average Labrador will find vaguely digestible.

But in America, they do food differently. Here, in the land of GM corn, 26 per cent obesity and a government which classifies pizza as a "vegetable", scientists have discovered a way to turn bacteria-ridden scraps from the abattoir floor into a substance called "pink slime", which is then sold to unwitting consumers of hamburgers, tacos and other beef-based junk products. The process involves sticking bovine off-cuts in a heated centrifuge, so they separate into a mixture of liquid fat and a putty-coloured paste. That substance is then treated with ammonium hydroxide (a chemical used in household cleaners and home-made bombs) to kill off salmonella and e-coli. Then it's mixed with regular beef and hey presto! you have "all natural" mince.

In 2001, it became legal to sell "pink slime" in America. Today, more than half the ground beef sold in America contains the stuff. The US Department of Agriculture (USDA), which supposedly regulates the food industry, does not require it to be mentioned on ingredient lists. Since its provenance is a cow, they insist, you can call it "beef". If you think that's a bit rum, you're not alone. For years, US foodies have earnestly cited "pink slime" as exhibit A in the list of liberties taken by a rapacious food industry.

Not for nothing, they argue, has the stuff been banned in Europe, where mechanically-separated meat from cows and sheep has been prohibited since the era of BSE.

It took an Englishman, however, to turn their complaints into national outrage. A year ago, Jamie Oliver jollified the US version of his Food Revolution TV show by using a cow called Scarlet and a tumble dryer to demonstrate how something he calls "crap" became a staple of the American diet. Video of his stunt was uploaded to YouTube, and shared via social media. Opposition to "pink slime" slowly built.

In January, McDonalds announced the removal of "pink slime" from its burgers. So did Burger King and Taco Bell. This month, as the product became a burgeoning national talking point, several major supermarkets went slime-free. School districts were allowed to start banning it and dozens swiftly did. Yesterday, Beef Products Inc, pink slime's leading manufacturer, shut down three of its four plants, citing swiftly cratering demand. According to the American Meat Institute, 600 jobs could now be lost.

"It's a sad day for the families," claimed a spokesman. Though not, one must presume, for their diets.

Did Mead Johnson Nutrition Squander Its Latest Sales Increase?

Posted on March 28, 2012 by ev1

Margins matter. The more Mead Johnson Nutrition (NYSE: MJN) keeps of each buck it earns in revenue, the more money it has to invest in growth, fund new strategic plans, or (gasp!) distribute to shareholders. Healthy margins often separate pretenders from the best stocks in the market. That's why we check up on margins at least once a quarter in this series. I'm looking for the absolute numbers, so I can compare them to current and potential competitors, and any trend that may tell me how strong Mead Johnson Nutrition's competitive position could be.

Here's the current margin snapshot for Mead Johnson Nutrition over the trailing 12 months: Gross margin is 63.0%, while operating margin is 23.3% and net margin is 13.8%.

Unfortunately, a look at the most recent numbers doesn't tell us much about where Mead Johnson Nutrition has been, or where it's going. A company with rising gross and operating margins often fuels its growth by increasing demand for its products. If it sells more units while keeping costs in check, its profitability increases. Conversely, a company with gross margins that inch downward over time is often losing out to competition, and possibly engaging in a race to the bottom on prices. If it can't make up for this problem by cutting costs -- and most companies can't -- then both the business and its shares face a decidedly bleak outlook.

Of course, over the short term, the kind of economic shocks we recently experienced can drastically affect a company's profitability. That's why I like to look at five fiscal years' worth of margins, along with the results for the trailing 12 months, the last fiscal year, and last fiscal quarter (LFQ). You can't always reach a hard conclusion about your company's health, but you can better understand what to expect, and what to watch.

Here's the margin picture for Mead Johnson Nutrition over the past few years.

Source: S&P Capital IQ. Dollar amounts in millions. FY = fiscal year. TTM = trailing 12 months.

Because of seasonality in some businesses, the numbers for the last period on the right -- the TTM figures -- aren't always comparable to the FY results preceding them. To compare quarterly margins to their prior-year levels, consult this chart.

Here's how the stats break down:

With recent TTM operating margins below historical averages, Mead Johnson Nutrition has some work to do.

Has modern science become dysfunctional?

The recent explosion in the number of retractions in scientific journals is just the tip of the iceberg and a symptom of a greater dysfunction that has been evolving the world of biomedical research say the editors-in-chief of two prominent journals in a presentation before a committee of the National Academy of Sciences (NAS) today.

"Incentives have evolved over the decades to encourage some behaviors that are detrimental to good science," says Ferric Fang, editor-in-chief of the journal Infection and Immunity, a publication of the American Society for Microbiology (ASM), who is speaking today at the meeting of the Committee of Science, Technology, and Law of the NAS along with Arturo Casadevall, editor-in -chief of mBio, the ASM's online, open-access journal.

In the past decade the number of retraction notices for scientific journals has increased more than 10-fold while the number of journals articles published has only increased by 44%. While retractions still represent a very small percentage of the total, the increase is still disturbing because it undermines society's confidence in scientific results and on public policy decisions that are based on those results, says Casadevall. Some of the retractions are due to simple error but many are a result of misconduct including falsification of data and plagiarism.

More concerning, say the editors, is that this trend may be a symptom of a growing dysfunction in the biomedical sciences, one that needs to be addressed soon. At the heart of the problem is an economic incentive system fueling a hypercompetitive environment that is fostering poor scientific practices, including frank misconduct.

The root of the problem is a lack of sufficient resources to sustain the current enterprise. Too many researchers are competing for too little funding, creating a survival-of-the-fittest, winner-take-all environment where researchers increasingly feel pressure to publish, especially in high-prestige journals.

"The surest ticket to getting a grant or job is getting published in a high profile journal," says Fang. "This is an unhealthy belief that can lead a scientist to engage in sensationalism and sometimes even dishonest behavior to salvage their career."

Funding is just one aspect of a very complex problem Casadevall and Fang see growing in the biomedical sciences. In a series of editorials in the journal Infection and Immunity they describe their views in detail, arguing that science is not as healthy as it could be or as it needs to be to effectively address the challenges facing humanity in the 21st century.

"Incentives in the current system place scientists under tremendous stress, discourage cooperation, encourage poor scientific practices and deter new talent from entering the field," they write. "It is time for a discussion of how the scientific enterprise can be reformed to become more effective and robust."

S.A. Life column will focus on aging, health

Posted on March 28, 2012 by ev1

Long before Steven Austad became a respected scholar in aging research, he wrangled lions, tigers, cougars and the occasional bear and elephant for the Hollywood film industry.

As a professor and interim director of the Barshop Institute for Longevity and Aging Studies at the UT Health Science Center at San Antonio, he also works with animals this time, studying a wide range of species to discover how they age.

Besides the usual lab rats and mice, his research subjects include clams that live up to 500 years.

There are hearts out there that have been beating since before Shakespeare was born, says Austad, 65. We're hoping that by studying some of these animals that have been so successful at resisting aging, we'll figure out ways to help humans stay healthy longer as well.

Austad joins S.A. Life today as a columnist writing about aging. His columns will appear every other Sunday.

Seventy-five percent of how well we age has to do with our lifestyle habits, not our genes, according to Austad.

So you're really in control of your health destiny, he says.

While researchers are close to having effective medications for aging, he says, at this point we can't tell you more than what your mother probably did, Austad says, which is all things in moderation, stay active mentally and physically and avoid bad habits, such as smoking, such as eating too much and drinking too much.

His column will address ways in which people can affect their health destiny, but also will inform his audience about this wonderfully interesting and complex process of aging that not just people but everything undergoes, he says.

Austad earned bachelor's degrees in English literature from UCLA and biology from California State, Northridge. His Ph.D. in biology is from Purdue University.

DNA traces cattle back to a small herd domesticated around 10,500 years ago

Posted on March 28, 2012 by ev1

Public release date: 27-Mar-2012 [ | E-mail | Share ]

Contact: Clare Ryan clare.ryan@ucl.ac.uk 44-020-310-83846 University College London

All cattle are descended from as few as 80 animals that were domesticated from wild ox in the Near East some 10,500 years ago, according to a new genetic study.

An international team of scientists from the CNRS and National Museum of Natural History in France, the University of Mainz in Germany, and UCL in the UK were able to conduct the study by first extracting DNA from the bones of domestic cattle excavated in Iranian archaeological sites. These sites date to not long after the invention of farming and are in the region where cattle were first domesticated.

The team examined how small differences in the DNA sequences of those ancient cattle, as well as cattle living today, could have arisen given different population histories. Using computer simulations they found that the DNA differences could only have arisen if a small number of animals, approximately 80, were domesticated from wild ox (aurochs).

The study is published in the current issue of the journal Molecular Biology and Evolution. Dr Ruth Bollongino of CNRS, France, and the University of Mainz, Germany; lead author of the study, said: "Getting reliable DNA sequences from remains found in cold environments is routine.

"That is why mammoths were one of the first extinct species to have their DNA read. But getting reliable DNA from bones found in hot regions is much more difficult because temperature is so critical for DNA survival. This meant we had to be extremely careful that we did not end up reading contaminating DNA sequences from living, or only recently dead cattle."

The number of animals domesticated has important implications for the archaeological study of domestication.

Prof Mark Thomas, geneticist and an author of the study based at the UCL Research Department of Genetics, Evolution and Environment: "This is a surprisingly small number of cattle. We know from archaeological remains that the wild ancestors of modern-day cattle, known as aurochs, were common throughout Asia and Europe, so there would have been plenty of opportunities to capture and domesticate them."

Prof Joachim Burger, an author of the study based at the University of Mainz, Germany, said: "Wild aurochs are very different beasts from modern domestic cattle.

Synthetic Biology Survey Requires Industry Response

Posted on March 28, 2012 by ev1

The Woodrow Wilson Synthetic Biology Project has released a public survey soliciting opinions on synthetic biology. It is a follow up to a recent paper on synthetic biology released in Nature, and it is filled with biased questions that revive some of the oldest misconceptions about the biotechnology industry. The results of the survey are expected to be released in May 2012.

BIO is encouraging members of the industry to participate in the survey and use the opportunity to address some of the biases and misconceptions.

Some of the loaded questions survey takers are asked to rate the relative importance of include:

Among these questions, ironically, is an admission that there currently is no widely agreed upon definition of synthetic biotechnology:

As members of the biotechnology industry, this survey presents an opportunity to get engaged and help fight misconceptions that have existed since the start of the biotech industry. Broad industry participation in filling out this survey and encouraging others to do so can help ensure the results, which will be released in May, will present a balanced view of synthetic biology and the biotechnology industry. We would hope the results rank developing a clear definition of synthetic biology as a higher priority than banning or labeling it.

You can also vote against a moratorium on synthetic biology in this poll in a Genetic Engineering & Biotechnology News article that looks at how fear has influenced public perception of most novel scientific endeavors like synthetic biology.

Powerful systems biology

Posted on March 28, 2012 by ev1

The methods of modern biology have made such leaps in recent years that it is easy to amass vast quantities of measurement data nowadays. Not only have we long been able to decode the genetic material of a living organism; at the same time, we can also determine which genes are activated how strongly in which cells, which cellular regulating molecules are present, which proteins are produced and which metabolic products are present in which concentrations. Far more difficult than collecting the data, however, is analysing it, generating new knowledge from it or proposing new scientific hypotheses. On the one hand, we are practically drowning in the flood of data in biologynowadays; on the other hand, we often lack key data, says Uwe Sauer, a professor at the Institute of Molecular Systems Biology.

According to Sauer, new computer methods can help analyse huge amounts of data. Together with Jrg Stelling, a professor at the Department of Biosystems, and an international team of researchers, he has now demonstrated the possibilities computer-aided biology can offer on the bacterium Bacillus subtilis.

Largest dataset

The researchers began by compiling an extensive collection of hundreds of thousands of specific biological values for the bacterium. What is exceptional about this data pool is that it does not reflect the state of the bacteria at a particular time, but rather a measuring sequence of anadaptation of the micro-organisms to environmental changes over several hours.

The scientists allowed the bacteria to grow on glucose in the lab first before supplementing it with malic acid, which the micro-organisms can use as an alternative nutrient. They then repeated the experiment the other way round. They took all the measurements of the biological parameters available to them at short time intervals, thus generating the largest dataset there currently is for such transitions.

More complex than thought

With the aid of newly developed and existing computer analysis methods, in this dataset the scientists were able to showthat the bacteria alter their metabolism and the basic control mechanisms inside the cell greatly for the comparatively simple adaptation to a new food source,for instance. The metabolic processes in the bacterium are very strongly linked and nature uses a far more complex control mechanism here than the simplest one possible that is theoretically imaginable, says Stelling. Instead of the expected changes of two handfuls of genes, almost half of the bacteriums 4,000 genes altered their activity.

The researchers were also able to ascertain why Bacillus subtilis can adapt much more quickly to malic acid than glucose. Using the computer methods, they were able to recognise genes that effectively act as a brake in the adaptation to glucose because they only adapt their activity slowly to the changed conditions.

Extensive possibilities of systems biology

Thanks to the analysis, the scientists ultimately found a hundred previously unknown regions in the bacteriums genetic material that perform a control function in the organism. And in a series of genes that had not yet been described more precisely until now, they were able to predict a function.

This includes novel gene and exon detection, gene fusion analysis, and sophisticated statistical and pathway analysis tools.

Agilents new bioinformatics software makes it easy for biologists with little experience in next-generation sequencing bioinformatics to manage and analyze their data by guiding them through wizard-driven workflows. It provides a convenient way to group, classify and explore data processed by a bioinformatics facility. GeneSpring 12.0 is also integrated with Agilents free eArray portal, enabling users to custom-design experiments through an easy-to-use interface.

Integrating data from heterogeneous omics technologies is a key component of systems biology research, which involves measuring the abundance of various biological entities in the same or closely related biological samples. The GeneSpring Pathway Architect module is designed to enable researchers to conduct joint pathway-level analysis of virtually any biological entity. This includes transcripts and splice variants, affected gene panels from variant analysis, metabolites and proteins.

The GeneSpring Pathway Architect module enables scientists to view and analyze curated pathway content. This is accomplished by leveraging WikiPathways, a publicly available resource for building, annotating and querying biological pathways. Mapping of biological identifiers across multiple public and proprietary annotation databases is also supported through integration with BridgeDB, another publicly available resource. Primary data from any of the single-omic experiments can be merged into a multi-omic experiment and used jointly to identify statistically significant pathways involved in many biological processes, such as signaling events, disease progression or toxicity.

GeneSpring 12.0 customization capabilities now include enhanced integration of the Jython and R programming languages. Using the embedded scripting editor, bioinformatics scientists can write, execute, and save their own algorithms and workflows in the GeneSpring 12.0 programming framework.

Agilent GeneSpring 12.0 was developed in partnership with Strand Scientific Intelligence, Inc. It is powered by Strands Avadis platform, which is designed to enable scientists to simplify and solve complex life science challenges.

Continued Smoking Can Spread Cancer

Posted on March 28, 2012 by ev1

Newswise Cigarette smoke cannot only cause cancer, but it's also responsible for the spread of it, according to research by UC Merced biochemistry Professor Henry Jay Forman.

Forman discovered tobacco smoke activates an enzyme called Src that causes cancer cells to spread to other parts of the body. The study will appear in the April 15 edition of Free Radical Biology and Medicine.

Cigarette smoke is the major cause of lung cancer, Forman said, but nearly half of lung cancer patients remain active smokers. Nonetheless, researchers haven't understood how cigarette smoke causes cancer to metastasize.

The lab was also able to prevent cigarette smoke from activating the enzyme by introducing an antioxidant. Forman's discovery could prove useful in the fight against cancer, as it creates more understanding on how it spreads and how antioxidants can help combat this.

Forman will present his findings on April 21 at the Experimental Biology 2012 conference in San Diego.

Forman coauthored the paper with a professor from the University of Padova in Italy. Forman served as a visiting professor during the summer while also conducting research.

In another paper, recently published in the Journal of Biological Chemistry, Forman collaborated with investigators at USC who are experts in looking at how cells maintain themselves using proteasome, which degrades old and damaged proteins. When cells are under oxidative stress, the proteasomes work faster to remove damaged proteins.

However, the lab discovered the signal used to increase a cell's defenses doesn't happen in old age, causing cells to die and turn malignant. The findings offer more insight into age-related problems, such as Alzheimer's disease. Both studies were supported by the National Institutes of Health.

Forman will continue his research this summer, focusing on three projects: understanding how differences in the expression of a particular enzyme increases human susceptibility to air pollution; studying how people with sickle cell trait may have a sickle cell crisis when doing severe exercise; and studying how cigarette smoke activates an enzyme that regulates changes in lung cancer cells that promote metastasis. The three projects are also funded by the National Institutes of Health.

Anatomy of a leak: how iPhones spill the ID of networks they access

Posted on March 28, 2012 by Danzig

An Ars story from earlier this month reported that iPhones expose the unique identifiers of recently accessed wireless routers, whichgenerated no shortage of reader outrage. What possible justification does Apple have for building this leakage capability into its entire line of wireless products when smartphones, laptops, and tablets from competitors don't? And how is it that Google, Wigle.net, and others get away with publishing the MAC addresses of millions of wireless access devices and their precise geographic location?

Some readers wanted more technical detail about the exposure, which applies to three access points the devices have most recently connected to. Some went as far as to challenge the validity of security researcher Mark Wuergler's findings. "Until I see the code running or at least a youtube I don't believe this guy has the goods," one Ars commenter wrote.

According to penetration tester Robert Graham, the findings are legit.

In the service of our readers, and to demonstrate to skeptics that the privacy leak is real, Ars approached Graham and asked him to review the article for accuracy and independently confirm or debunk Wuergler's findings.

"I can confirm all the technical details of this 'hack,'" Graham, who is CEO of Errata Security, told Ars via e-mail. "Apple products do indeed send out three packets that will reveal your home router MAC address. I confirmed this with my latest iPad 3."

He provided the image at the top of this post as proof. It shows a screen from Wireshark, a popular packet-sniffing program, as his iPad connected to a public hotspot at a Starbucks in Atlanta. Milliseconds after it connected to an SSID named "attwifi" (as shown in the section labeled #1), the iPad broadcasted the MAC address of his Linksys home router (shown in the section labeled #2). In section #3, the iPad sent the MAC address of this router a second time, and curiously, the identifier was routed to this access point even though it's not available on the local network. As is clear in section #4, the iPad also exposed the local IP address the iPad used when accessing Graham's home router. All of this information is relatively simple to view by anyone within radio range.

The image is consistent with one provided by Wuergler below. Just as Wuergler first claimed, it shows an iPhone disclosing the last three access points it has connected to.

Graham used Wireshark to monitor the same Starbucks hotspot when he connected with his Windows 7 laptop and Android-based Kindle Fire. Neither device exposed any previously connected MAC addresses. He also reviewed hundreds of other non-Apple devices as they connected to the network, and none of them exposed previously accessed addresses, either.

As the data makes clear, the MAC addresses were exposed in ARP (address resolution protocol) packets immediately after Graham's iPad associated with the access point but prior to it receiving an IP address from the router's DHCP server. Both Graham and Wuergler speculate that Apple engineers intentionally built this behavior into their products as a way of speeding up the process of reconnecting to access points, particularly those in corporate environments. Rather than waiting for a DHCP server to issue an IP address, the exposure of the MAC addresses allows the devices to use the same address it was assigned last time.

Midlands Vet Uses Stem Cell Therapy for Pets in Pain

Posted on March 27, 2012 by ev1

Columbia, SC (WLTX) --What if your pet couldn't walk anymore? One Midlands vet is using stem cell therapy to help.

For Beth Phibbs it's almost like a turning back of the hands of time.

"I call her my little miracle dog, because she's doing things she used to do," said Phibbs. "Now she's not on any medication, and she can go up and down the steps and she runs and jumps and things that she used to do when she was five."

Phibbs has spent the last 13 years loving and looking after her pet dog Maggie, and when she pet began to develop arthritis and a limp she had to take action. But when the first treatments stopped working, Phibbs and Maggie had to look to another options, dog stem cell therapy.

"I had no idea that animals were able to have they type of procedures," she said.

Dr. Kenneth Banks a veterinarian with the Bank Animal Hospital, performed the surgery for Maggie using her own stem cells in the one day procedure.

Banks said the stem cell therapy not only cost less than some other options, but was less invasive and had a quicker recovery time as well.

Still with about three similar procedures under his belt, even he didn't expect to see a such change in maggie just 40 days after the surgery.

"I wasn't sure we were gonna get the results this fast, we were expecting results, maybe not a good as she's done. We're real happy with her results," said Banks.

Now, after three years on medication and walking with a limp, Maggie's getting used to a new way of life -- one with out pain in her golden years.
