New Rochelle, NY, July 21, 2014In Alzheimer's disease, accumulation of amyloid plaque in the brain is believed to play an important role in many characteristic disease symptoms, including memory loss and other mental state changes. But how these plaque deposits affect brain function is not well understood. Important new study results showing that plaque buildup in one area of the brain can negatively affect metabolism in a more distant brain region have been published in Brain Connectivity, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Brain Connectivity website at http://online.liebertpub.com/doi/full/10.1089/brain.2013.0212 until August 21, 2014.

As part of a special issue focused on Alzheimer's disease, Elisabeth Klupp and coauthors, Technische Universtt Mnchen (Munich and Garching, Germany) and University Hospital of Cologne, Germany, present the results of an imaging-based study demonstrating that amyloid buildup in one brain region can impair brain cell metabolism and activity another in remote brain region not affected by amyloid plaque accumulation. The regions studied were part of the same functional network but are located remotely from each other in the brain. The authors suggest this long-distance effect may be the result of diminished neuronal signals originating from the amyloid-affected brain region to the remote amyloid-unaffected brain region. The findings are discussed in the article "In Alzheimer's Disease, Hypometabolism in Low-Amyloid Brain Regions May Be a Functional Consequence of Pathologies in Connected Brain Regions."

"This research may be an important new discovery that links two important hypotheses in Alzheimer's disease research: the amyloid buildup hypothesis and the network degenerating hypothesis," says Christopher Pawela, PhD, Co-Editor-in-Chief and Assistant Professor, Medical College of Wisconsin.

New Rochelle, NY -- The Human Microbiome Project (HMP) is a global initiative to identify and characterize the microorganisms present at multiple sites in the human body. An international team of researchers reports on new ways to harness the results of the HMP and discusses how changes in the microbiome might affect human health, disease, immunity, and importantly, the safety and effectiveness of drug treatment in a Review article that is part of the special issue "OMICS in Africa: Moving 21st Century Integrative Biology from Lab to Village to Innovation Ecosystems," of OMICS: A Journal of Integrative Biology, the peer-reviewed interdisciplinary journal published by Mary Ann Liebert, Inc., publishers. The issue is available on the OMICS website.

In the article "Pharmacomicrobiomics: The Impact of Human Microbiome Variations on Systems Pharmacology and Personalized Therapeutics," senior author Ramy Karam Aziz and coauthors propose a "microbiome cloud model" to understand the variation in an individual's microbiome composition within and between individuals and how that variability makes it difficult to define the human microbiome. They present detailed examples of microbiome changes related to colorectal cancer, use of antibiotics, and pharmacomicrobiomics or drug-microbiome interactions in relation to personalized healthcare.

In the Commentary "Translating Biotechnology to Knowledge-Based Innovation, Peace, and Development? Deploy a Science Peace CorpsAn Open Letter to World Leaders," Nezih Hekim, SANKO University, Turkey and coauthors in 15 countries from around the world joined forces with OMICS Editor-in-Chief Vural zdemir, MD, PhD, DABCP Gaziantep University, Faculty of Communications, School of Journalism, Gaziantep Turkey, to call for the creation of a global Science Peace Corps. This idea and initiative would entail volunteer work in life sciences translational research for no less than 6 weeks and up to 2 years in any region of the world. The topics could relate to all fields of medicine "as long as they are linked to potential or concrete endpoints in development, foreign policy and/or peace scholarship domains." The authors describe the proposed Science Peace Corps as a "new instrument in the global science governance toolbox" that would advance "the emerging concept of 'one health'encompassing human, environmental, plant, microbial, ecosystem, and planet health."

Original research articles in this special issue cover topics of relevance to Africa such as HIV transmission and epidemiology, maternal health, malaria, common complex diseases such as deafness, and policy action for sickle cell anemia that is greatly impacting the African populations.

African science and knowledge-based innovation are central to a deep understanding of pathophysiology, prevention and treatment of human diseases, discovery and development of novel diagnostics, as well as ecosystem health. OMICS Editor-in-Chief Vural zdemir summarizes the special issue as "very much in the spirit of the integration we seek to achieve in the Journal across biotechnologies, their variegated applications in life sciences, and between technology and global society, so that knowledge-based innovations can responsibly integrate at a community level."

Dont allow field trials of GM crops: farmers, activists

Posted on by

The recent decision of the Genetic Engineering Appraisal Committee (GEAC) to allow field trials of GM rice, mustard, cotton, chickpea and brinjal has been met with strong opposition from farmers groups and environmental activists.

Seeking the intervention of Union Environment and Forests Minister Prakash Javdekar, the Bhartiya Kisan Union has asked for annulment of the approvals.

Questioning the need for release of genetically modified organisms (GMOs) in the fields, the BKU leaders said they were concerned over the nations seed and food sovereignty.

This is because most genes as well as transgenic processes are already patented and these Intellectual Property Rights work for the monopolistic benefit of the profiteering multinational corporations. The ease with which a transgenic technology allows corporations to claim ownership rights over seeds makes it attractive to them to hype why the world needs GMOs and seek control over entire food chains from production to marketing jeopardising the livelihood security of farmers, BKU leaders Naresh Tikait, Dharmendra Malik and Yudhveer Singh said in a letter to the Minister.

In a separate letter to Mr. Javadekar, the Coalition for GM-free India said the GEAC approvals came at a time the Supreme Court was about to pronounce its orders on the issue of field trials of GM crops, based on the recommendations of the Courts Technical Expert Committee (TEC). Realising the potential of field trials to contaminate the seed, food supply chains and environment, and owing to the lack of a proper regulatory system, the TEC has recommended a moratorium on open-air field trials.

It is ironical that the BJP manifesto promise of not allowing GM foods in the country without full scientific evaluation of their long-term effects on soil, production and biological impact on consumers is the main subject for this PIL petition in the Supreme Court. It was pending the decision of the apex court that former Environment Minister Jayanthi Natarajan had stayed GEAC meetings... The last time the GEAC approved some GMOs for open- air field testing, prominent BJP leaders had condemned the move, Rajesh Krishnan of the coalition said.

New HIV prevention recommendations combine biomedical, behavioral approaches

Posted on by

In an innovative approach to HIV prevention, an interdisciplinary group of experts has come together for the first time to lay out a framework of best practices to optimize the role of the clinician in achieving an AIDS-free generation. The guidelines, which will be published online in the Journal of the American Medical Association (JAMA), integrate both cutting-edge biomedical advances and evidence-based behavioral interventions for the care of people living with HIV or at high risk for HIV infection.

The recommendations, developed by an expert volunteer panel assembled by the International Antiviral (formerly AIDS) Society-USA (IAS-USA), are intended as guidelines for clinicians to implement a combined biomedical-behavioral approach to HIV care and prevention. They are based on a comprehensive review of data that was either published or presented at scientific conferences over the past 17 years.

Among the new recommendations is a call for the use of antiretroviral therapy (ART), which suppresses HIV replication and virtually eliminates the risk of transmitting the virus, for all HIV-infected individuals and as pre-exposure prophylaxis (PrEP) for HIV-uninfected individuals at high risk of infection. The guidelines emphasize the integration of behavioral and social interventions -- such as psychosocial counseling or treatment for drug dependence -- in health care systems to help individuals living with HIV or at high risk for infection to access and remain in high quality HIV care.

"The tools to prevent HIV infection and disease progression are better than ever, but providers need encouragement and support to integrate best practices in communication and counseling with the biomedical measures that can render patients less- and ideally non-infectious," says Jeanne M. Marrazzo, MD, MPH, professor of medicine at the University of Washington; medical director of the Seattle STD/HIV Prevention Training Center; a co-chair of the IAS-USA panel; and corresponding author of the paper.

According to the recommendations, the availability of combination antiretroviral therapy (ART) has changed the lives of millions of individuals living with HIV, transforming HIV from a fatal infection to a manageable chronic disease. But while the incidence of new HIV-1 infections worldwide has decreased by an estimated 33 percent since 2001, it still remains high -- approximately 2.3 million new infections occurred in 2012. In the United States alone, approximately 50,000 new infections occur each year -- a number that has remained largely unchanged since the 1990s.

"We are at a time where scientific advances in HIV allow us to effectively implement interventions that could stop HIV transmission," says Carlos del Rio, MD, chair of the Department of Global Health at the Rollins School of Public Health at Emory University, professor of medicine at Emory University School of Medicine, co-director of the Emory Center for AIDS Research, co-chair of the IAS-USA Panel, and a member of the IAS-USA volunteer board of directors. "But the success of both biomedical and behavioral HIV prevention measures depends on clinicians' ability and willingness to implement them."

"These guidelines provide a practical, science-based approach that any clinician can implement," says David Holtgrave, PhD, chair of the Department of Health, Behavior and Society at the Johns Hopkins Bloomberg School of Public Health and a co-chair of the IAS-USA Panel. "They are designed to promote the integration of the best available services -- both behavioral and biomedical -- and to create a clear pathway to access these services and realize their full benefit."

The panel's recommendations include the following:

The recommendations note that while implementing them may present structural, economic, or political challenges, the benefits should be substantial in preventing disease progression, promoting the gain of healthy life years and preventing new HIV infections.

Medical tourism, once the exclusive preserve of the rich, is growing and changing as hospitals and clinics offer farflung patients advantages hard to come by in China whether it be high-tech therapy, less-expensive care or alternative treatments.

In China, home to a growing number of travelling patients, more foreign medical tourists are seeking care either to save money or for such treatments as traditional Chinese medicine.

"In European countries such as Turkey and Cyprus, more than half of people are not covered by public insurance, so Chinese medical institutions have big opportunities," says Li Jingwen, general manager in Beijing for McBridge, a medical business consultant with offices in China and Germany.

At the same time, outbound tourists from China are starting to go for hospitals and clinics in many developed countries.

They are showing up not just with shopping bags and cameras, but also in increasing numbers with their medical records in countries like South Korea, Singapore, Europe and the United States.

They are filling hospital beds and surgical suites for treatments as diverse as plastic surgery, extensive checkups and cancer treatment.

GEAC clears import of GM soyabean oil

Posted on by

India's biotech regulator Genetic Engineering Appraisal Committee (GEAC) has given green signal for the import of Genetically Modified (GM) soybean oil.

"Three applications for import of GM Soybean oil were permitted as highly processed food like oil do not contain detectable DNA or Proteins. The same was confirmed by Central Food Technological Research Institute (CFTRI) Mysore after testing of the oil samples," GEAC said, adding that more than 70 countries are importing GM soybean and canola oil.

The statutory body, which held its 121st meeting on Friday, also permitted confined field trials of 13 GM crops, including rice, brinjal, chickpea, mustard and cotton, out of the 15 cases it considered.

GEAC Chairman Hem Pande said "field trials for certain varieties of GM crops including rice, brinjal, chickpea, mustard and cotton had been cleared".

However, the field trials, or small scale experiments, on these crops were subject to No Objection Certificate (NOC) from state governments.

During the GEAC meeting, three cases of pharmaceuticals were also considered of which two were deferred and one case pertaining to revalidation of the GEAC nod was permitted.

Officials said GEAC had "virtually" not met for almost two years from April 2012 to March 2014 due to which which decision on 79 applications for field trials remained pending.

These 79 cases, recommended by Review Committee on Genetic Manipulation (RCGM) under the Department of Biotechnology, included 37 cases of revalidation and 42 new cases involving confined (regulated) field trials related to cotton, rice, castor, maize, wheat, groundnut, sugarcane, chickpea, mustard, sorghum and brinjal.

The GEAC on Friday also decided to constitute a sub-committee to review the toxicology data generated by the applicants of GM brinjal developed by BejoSheetal P Limited and GM mustard developed by Delhi University South Campus in view of concerns raised by some of the members.

An official said all GM crops field trials are subject to stringent norms which are as per the international standards.

Can betting against yourself online help you save money?

KARLA MURTHY:Like many Americans, Barbara Nordin, a freelance editor and writer in Charlottesville, Virginia often procrastinates.

BARBARA NORDIN:I knew that professionally I needed a website. And I, had the domain name, I, you know, made lists of what I put on it for eons

KARLA MURTHY:But in 2012, she learned about an online program that would push her to get the project done or else she would lose $50 dollars. Its an example of behavioral economics at work, according to Dean Karlan, a Yale University economist.

DEAN KARLAN:Its about realizing that youre going to respond to incentives. If you dont like the way youre going to respond, you can change those incentives. You can change the price of things by being a bit self-aware and thinking ahead.

KARLA MURTHY:Understanding how people respond to incentives is central to behavioral economics, a field which looks at the psychology behind economic decisions. This new science is being used to help people nudge them on everything from making better healthcare decisions to maximizing energy efficiency.

But one of its biggest uses is in improving peoples financial choices. An area in which many Americans dont excel. The personal savings rate is less than half of what it was a generation ago. And an estimated 56 million Americans have virtually no retirement savings.

JOSH WRIGHT:Financial education has actually had not great results in terms of getting people to change behavior.

KARLA MURTHY:Josh Wright is the executive director of Ideas42, a nonprofit that works with companies, foundations, and governments to apply lessons from behavioral economics. He points to a study that showed how committing to save more, not even today, but in the future, dramatically increased retirement savings.

JOSH WRIGHT:One of the interesting things about peoples financial lives is, they usually know what they wanna do or they have an intention to save more or spend less get greater control over their finances. And a lot of it has to do with following through on those desires and intentions. And theres a lot that behavioral science can do along with technology to help us help people help themselves, really, to do what they wanna do.

KARLA MURTHY:And new businesses have taken some of these insights to heart. Washington D.C.-based HelloWallet provides financial computer software, including budgeting and retirement tools for employees of big companies across the country.

Can you be nudged into saving money? Some companies are banking on it

Posted on by

Evidence from behavioral economists, researchers who study the psychology behind economic decision making, has been applied before to everything from getting people to become organ donors to helping them reduce water use.

But now, its helping people make better financial decisions and save more money. And increasingly major financial companies are using it to help consumers get a better fiscal foothold.

Josh Wright, executive director of Ideas42, a nonprofit consulting firm that works with companies to apply research from behavioral science, says that hes seen a shift in the finance industry with firms putting more emphasis on encouraging smarter financial decisions.

A lot of these concepts are now being used by financial institutions to start to think about designing products that are better for people, Wright said. And this is particularly true for people on the lower end of the income spectrum.

Wright cites American Express as one such company. In 2012, the company partnered with Walmart to launch Bluebird, a prepaid card aimed at consumers who dont use traditional banks. With Bluebird, users can pay bills, load cash at Walmart and even receive paychecks using direct deposit.

Notably, though, Bluebird lets users set up a savings account within the card just one example of a small tweak companies are making to help generate more responsible behavior, Wright said.

And in the next several months, Ideas42, which has been working with American Express, will be helping conduct studies with the companys Serve prepaid card to see how it can influence consumer behavior.

Well actually be able to see if it helps people, Wright said.

JP Morgan Chase is also hoping to use behavioral economics to help improve peoples financial behavior.

GEAC clears field trials for GM crops

Posted on by

The Genetic Engineering Approval Committee (GEAC) on Friday gave the green signal for field trials of genetically modified (GM) rice, mustard, cotton, chickpea and brinjal at its meeting in Delhi.

Hem Kumar Pande, chairperson of the GEAC told The Hindu that meetings were not held for a year since March 2013 and there was a backlog of 70 applications pending since 2011-12 of which 60 have been cleared so far.

Fridays agenda dealt with 15 items and cleared field trials of rabi crops. In the three meetings since March 2014, the GEAC took up revalidation of data and approved kharif crops, Mr. Pande pointed out.

While the GEAC has approved the commercial release of Bt brinjal it has been stayed by the Ministry of Environment and Mr. Pande said the government would have to take a decision on this. The only genetically modified crop approved for release in India is cotton.

So far about 20 GM crops are under trial at various stages, he said and the new approvals were for the first stage of trials on one-acre plots. He said unless research in Indian conditions is allowed, the viability of these crops would not be known.

Meanwhile, Dr. Pushpa M. Bhargava, founder and former director, Centre for Cellular and Molecular Biology, Hyderabad and Supreme Court appointee to the GEAC told The Hindu that he was particularly concerned about the approval granted to import GM soyabean oil.

According to my technical information, no oil made from a GM product is free of foreign DNA. Even in small amounts, DNA is genetic material and can cause damage. There is incontrovertible evidence that oils made from GM material do contain foreign DNA, he said.

Three companies - Bayer Bio Sciences, Monsanto and BASF have been allowed to import the oil. The last time there was objection to the import of soyabean oil; samples were sent for testing to the Central Food Technological Research Institute (CFTRI), which gave it a clean chit.

Dr. Bhargava questioned the sensitivity of the tests that were carried out. The next meeting of the GEAC will be held in August. However, the country is already using cotton seed oil after the advent of transgenic cotton.

Members who attended the meeting said that while companies provided data to support their proposals there was no system of verifying the validity of the data. They also objected to some dissenting voices, which were not recorded in the minutes of the meeting the last time and the Committee said it would be recorded now on.
