(Boston) Investigators at Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have identified a new gene linked to post-traumatic stress disorder (PTSD). The findings, published online in Molecular Psychiatry, indicate that a gene known to play a role in protecting brain cells from the damaging effects of stress may also be involved in the development of PTSD.

The article reports the first positive results of a genome-wide association study (GWAS) of PTSD and suggests that variations in the retinoid-related orphan receptor alpha (RORA) gene are linked to the development of PTSD.

Mark W. Miller, PhD, associate professor at BUSM and a clinical research psychologist in the National Center for PTSD at VA Boston Healthcare System was the study's principal investigator. Mark Logue, PhD, research assistant professor at BUSM and Boston University School of Public Health and Clinton Baldwin, PhD, professor at BUSM, were co-first authors of the paper.

PTSD is a psychiatric disorder defined by serious changes in cognitive, emotional, behavioral and psychological functioning that can occur in response to a psychologically traumatic event. Previous studies have estimated that approximately eight percent of the U.S. population will develop PTSD in their lifetime. That number is significantly greater among combat veterans where as many as one out of five suffer symptoms of the disorder.

Previous GWAS studies have linked the RORA gene to other psychiatric conditions, including attention-deficit hyperactivity disorder, bipolar disorder, autism and depression.

"Like PTSD, all of these conditions have been linked to alterations in brain functioning, so it is particularly interesting that one of the primary functions of RORA is to protect brain cells from the damaging effects of oxidative stress, hypoxia and inflammation," said Miller.

Participants in the study were approximately 500 male and female veterans and their intimate partners, all of whom had experienced trauma and approximately half of whom had PTSD. The majority of the veterans had been exposed to trauma related to their military experience whereas their intimate partners had experienced trauma related to other experiences, such as sexual or physical assault, serious accidents, or the sudden death of a loved one. Each participant was interviewed by a trained clinician, and DNA was extracted from samples of their blood.

The DNA analysis examined approximately 1.5 million genetic markers for signs of association with PTSD and revealed a highly significant association with a variant (rs8042149) in the RORA gene. The researchers then looked for evidence of replication using data from the Detroit Neighborhood Health Study where they also found a significant, though weaker, association between RORA and PTSD.

New Rochelle, NY, August 7, 2012The body's natural reaction to reject replacement proteins represents a major obstacle to the successful use of gene therapy to cure a range of life-threatening diseases. A novel method that uses the body's own immune cells to induce tolerance to a specific protein was shown to suppress the rejection response, as described in an article in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com). The article is available free online at the Human Gene Therapy (http://www.liebertpub.com/hum) website.

"A major limitation of protein and gene therapeutics is the associated immune responses which can cause toxicity and diminish efficacy," says James M. Wilson, MD, PhD, Editor-in-Chief, and Director of the Gene Therapy Program, Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine, Philadelphia. "This clever use of immune modulators may prevent these untoward immune responses from happening."

Exposing a type of immune cell called dendritic cells to a specific therapeutic protein in the presence of immune-stimulating chemicals called cytokines leads to the creation of tolerogenic dendritic cells. These cells, when introduced into mice that are then given gene therapy designed to deliver the therapeutic protein of interest, allow the mice to tolerate, and not reject, the therapeutic protein.

Current approaches to induce partial or full tolerance to proteins replaced via gene therapy are expensive and are unsuccessful in as many as 40% of cases. The method described in this article by Gautam Sule and colleagues from Baylor College of Medicine and Howard Hughes Medical Institute, Houston, TX, offers advantages to support the long-term success of gene therapies. The authors report their findings in "Cytokine-Conditioned Dendritic Cells Induce Humoral Tolerance to Protein Therapy in Mice."

Fainting is a fairly common occurrence in our society and about 25 percent of us will experience it at some point in our life. And now, a new study has found that there is a strong link between fainting and family. Studying identical and fraternal twins, researchers from Australia and the US suggest people who are predisposed to fainting get it through genetics.

Described as a sudden, brief loss of consciousness after blood pressure drops from the brain, fainting normally occurs due to an internal factor dehydration, heart problems, etc. But sometimes, black outs occur to some kind of out-of-body trigger, such as the sight of blood or after emotional distress. This type of fainting is known as vasovagal syncope.

Typically, fainting itself is not considered dangerous. Most people usually wake up a few seconds after they pass out. The dangerous part comes when they fall and possibly suffer an injury in the process.

The question of whether fainting is caused by genetic factors, environmental factors or a mixture of both has been the subject of debate, said study author Samuel F. Berkovic, MD, FRS, of the University of Melbourne in Victoria, Australia, and a member of the American Academy of Neurology.

Publishing the findings Neurology, the medical journal of the American Academy of Neurology, researchers questioned 51 sets of twins of the same gender between the ages of 9 and 69, of which at least one had a history of fainting. The team also gathered information about family history of fainting. They discovered that 57 percent of the twins in the study reported having typical fainting triggers.

Berkovic and colleagues found that among twins where one fainted, identical twins were nearly twice as likely to both faint compared to fraternal twins. The risk of fainting due to internal factors was also much higher in the identical twins than in the fraternal twins. The identical twins were much more likely to both experience fainting associated with typical triggers as well. In non-twin relatives, frequency of fainting was low, suggesting the way fainting is inherited does not rely on a single gene.

Our results suggest that while fainting appears to have a strong genetic component, there may be multiple genes and multiple environmental factors that influence the phenomenon, said Berkovic.

Simply put, there is now strong evidence that a simple faint, for example, one caused by sight of blood, fear, or unpleasant thoughts, can have a genetic component, Ezriel Kornel, MD, a neurologist at Northern Westchester Hospital in Mount Kisco, New York, told Brenda Goodman at WebMD.

Berkovic noted that even though identical twins were more likely to report outside triggers for their spells, it wasnt always the same trigger for both twins.

CAMDEN A top national award for promising research scientists has been presented to Princeton resident Nir Yakoby, an assistant professor of biology at Rutgers UniversityCamden.

Yakoby has received a prestigious CAREER Award from the National Science Foundation. The five-year, $686,544 award, which is reviewed and renewed annually based on the scientific progress of the project, supports the RutgersCamden researcher's project "Dynamics and Diversity of Bone Morphogenetic Protein Signaling in Epithelial Cells."

The grant will allow Yakoby and his research lab team to study the processes that occur during the time that cells decide what to become. RutgersCamden student researchers will join Yakoby in using the fruit fly Drosophila as an experimental system to study how very similar layers of cells produce different numbers of tubes. Through this work, the RutgersCamden researcher will seek to understand how changes in the bone morphogenetic protein (BMP) signal create different morphologies.

In explaining his research, Yakoby posits the following questions: "Why do we have two arms and two legs and not three of each? Why do we have five fingers and not six?" The RutgersCamden researcher seeks to find those answers by examining the signals and processes that advise cells as they form organs.

"These questions are particularly intriguing since the cells in the human body all contain the same genetic information. However, the clear cells in the eyes' corneas are obviously very different from the cells that secrete insulin in the pancreas," notes Yakoby.

A major goal of the NSF CAREER Award is to integrate academic teaching with research in the lab. RutgersCamden students will participate in this research.

In the Yakoby Lab, RutgersCamden students use the fruit fly Drosophila as an experimental system to study how a layer of cells in the fly ovaries form an eggshell. The eggshell protects the developing embryo from the dry environment while allowing for respiration through tube-like snorkels called dorsal appendages (DAs). Just as animals have different numbers of fingers, the numbers of the eggshells' respiratory tubes differ among Drosophila species. Thus, the eggshell provides a unique opportunity to study how very similar layers of cells produce different numbers of tubes.

In humans, a signal named the bone morphogenetic protein (BMP) is necessary to define the development of fingers. The same signal controls the formation of the DAs on the Drosophila eggshell. Through his CAREER Award, Yakoby proposes to study how changes in the BMP signal allow for the formation of different numbers of DAs. Since the BMP signal is highly conserved between Drosophila and humans, understanding how changes in this signal create different morphologies will help to understand tissue pathologies and developmental defects which are associated with mal-regulation of the BMP signal.

Sigma-Aldrich Corporation (SIAL) recently announced that Sigma Advanced Genetic Engineering (:SAGE) Labs, an initiative of Sigma Life Science, has extended its partnership with Autism Speaks to develop the first rat models with modified autism associated genes to enhance discovery and translational autism research. Autism Speaks is the biggest autism science and advocacy organization in the U.S.

Extension of the existing partnership between Sigma and Autism Speaks was on the heels of some behavioral studies, which revealed that the first two publicly available gene-knockout rats display unique characteristics of autism like social deficits and repetitive behaviors. Autism Spectrum Disorder can be experimented on animals to better study its cause and treat the individuals suffering from the disorder. SAGE labs and Autism Speaks are set to generate genetically modified rat models of key autism-associated genes, including CNTNAP2 and MET. CNTNAP2 and MET are knockout rat lines and are expected to be available in 2013. The expanded collaboration will ensure that new models are developed and are made available to speed up the translational research continuum.

Sigma Life Science is the biological products and services arm of Sigma-Aldrich Corporation. Sigma-Aldrich, a life-science and specialty chemical company, released its second-quarter 2012 earnings last month.

The company posted adjusted earnings of 97 cents per share in the quarter, in line with the Zacks Consensus Estimate but ahead of the year-ago earnings of 93 cents per share. Profit, as reported, marginally increased to $115 million or 94 cents per share in the quarter from $113 million or 91 cents a year ago.

Revenues came in at $664 million in the quarter, up 4% year over year but below the Zacks Consensus Estimate of $673 million. Acquisitions contributed 6% to the growth while foreign exchange translation had an unfavorable impact of 5%. The company saw growth across its Research Chemicals and Fine Chemicals (SAFC) divisions.

Moving ahead, Sigma-Aldrich expects organic growth to be in low-to-mid single digits in 2012, down from the earlier expectation of mid single-digits. Macroeconomic uncertainties may hinder its Research Chemicals business whereas growth in Bioscience and Hitech is expected to drive SAFC sales for the remainder of the year. The acquisitions of BioReliance and Research Organics are expected to boost sales by 6%.

Sigma-Aldrich currently maintains a Zacks #4 Rank, which translates into a short-term (1 to 3 months) Sell rating. We have a long-term Neutral recommendation on the stock.

Youre at the supermarket doing your grocery shopping. As you move up and down the aisles, you notice something different: new labels on several of your staple food items. Pasta, cereal, chips, sweet corn and yellow squash all now have a distinct marking that says either genetically engineered or partially produced with genetic engineering.

How might this change your food choices?

In November, voters will have a chance to decide whether such information must be labeled on food products under Proposition 37. If passed, it would be the first such law in the U.S.

We dont know how or if it will change consumers approach to eating, said Lori Sinsley, deputy director of the California Right to Know Campaign. They can use the labels to make more informed choices about what they eat, which is how a market is supposed to work.

Genetically modified organisms, or GMOs, are crops that have had their DNA artificially altered with genes from plants, animals, viruses or bacteria. This type of genetic modification occurs in a laboratory and cannot be found in nature, Sinsley said.

Many processed foods are made with genetically engineered ingredients whether shoppers know it or not. Processed items commonly contain genetically modified corn, sweet corn, soy and canola. Even common produce items such as yellow squash, zucchini and papaya are genetically modified, as well as other crops such as cotton.

It is our fundamental right to know what is in our food, said Zuri Allen, social media coordinator for both Right to Know and the Organic Consumers Association. Its as American as apple pie.

There are exemptions in the initiative food derived entirely from an animal that hasnt been genetically engineered itself, regardless of the animals possible consumption of genetically modified foods; alcoholic beverages; and food intended for immediate consumption (as in restaurants). Producers of foods that are fully or partially genetically engineered and are not exempt would not be able to advertise their products as natural or naturally made.

I have children and I know that I have a right to know what Im buying and feeding to my family, said Susan Lang, a volunteer for Right to Know and co-leader of the Sacramento County group Label GMOs. California voters really need to ask themselves why the opposition doesnt want them to know whats in their food.

While genetic engineering can sound scary, its important to know that these foods are not made in a lab, said Stop the Costly Food Labeling Proposition spokeswoman Kathy Fairbanks. The seeds are genetically altered to use water more efficiently and resist pests. Some foods, such as the papaya, are genetically engineered to survive devastating diseases.

Newswise August 6, 2012 (Bronx, NY) A new genetic analysis focusing on Jews from North Africa has provided an overall genetic map of the Jewish Diasporas. The findings support the historical record of Middle Eastern Jews settling in North Africa during Classical Antiquity, proselytizing and marrying local populations, and, in the process, forming distinct populations that stayed largely intact for more than 2,000 years. The study, led by researchers at Albert Einstein College of Medicine of Yeshiva University, was published online today in the Proceedings of the National Academy of Sciences.

Our new findings define North African Jews, complete the overall population structure for the various groups of the Jewish Diaspora, and enhance the case for a biological basis for Jewishness, said study leader Harry Ostrer, M.D., professor of pathology, of genetics and of pediatrics at Einstein and director of genetic and genomic testing for the division of clinical pathology at Montefiore Medical Center. Dr. Ostrer noted that obtaining a comprehensive genetic fingerprint of various Jewish subpopulations can help reveal genetic links to heart disease, cancer, diabetes and other common diseases.

In a previous genetic analysis, the researchers showed that modern-day Sephardic (Greek and Turkish), Ashkenazi (Eastern European) and Mizrahi (Iranian, Iraqi and Syrian) Jews that originated in Europe and the Middle East are more related to each other than to their contemporary non-Jewish neighbors, with each group forming its own cluster within the larger Jewish population. Further, each group demonstrated Middle-Eastern ancestry and varying degrees of mixing with surrounding populations. Two of the major Jewish populationsMiddle Eastern and European Jewswere found to have diverged from each other approximately 2,500 years ago.

The current study extends that analysis to North African Jewsthe second largest Jewish Diaspora group. Their relatedness to each other, to other Jewish Diaspora groups, and to their non-Jewish North African neighbors had not been well defined. The study also included members of Jewish communities in Ethiopia, Yemen and Georgia. In all, the researchers analyzed the genetic make-up of 509 Jews from 15 populations along with genetic data on 114 individuals from seven North African non-Jewish populations.

North African Jews exhibited a high degree of endogamy, or marriage within their own religious and cultural group in accordance with custom. Two major subgroups within this overall population were identified: Moroccan/Algerian Jews and Djerban (Tunisian)/Libyan Jews. The two subgroups varied in their degree of European mixture, with Moroccan/Algerian Jews tending to be more related to Europeansmost likely stemming from the expulsion of Sephardic Jews from Spain during the Inquisition, starting in 1492. Ethiopian and Yemenite Jewish populations also formed distinctive genetically linked clusters, as did Georgian Jews .

Dr. Ostrers paper is titled, North African Jewish and non-Jewish populations form distinctive, orthogonal clusters.

New Study Defines the Genetic Map of the Jewish Diasporas

Recommendation and review posted by Bethany Smith

North African Jews are more closely related to Jews from other parts of the world than they are to most of their non-Jewish neighbors in North Africa, a study has found.

Furthermore, their DNA carries a record of their migrations over the centuries: Some bits trace back to the Middle Eastern peoples thought to have migrated to North Africa more than 2,000 years ago, while other bits are linked to Spanish and Portuguese Jews who fled to North Africa after their expulsion from the Iberian Peninsula in the late 15th century, the study's authors said.

The discovery falls in line with other research showing that Jewish people from Europe and the Middle East share more DNA with one another than they do with outside groups, said Dr. Harry Ostrer, a medical geneticist at the Albert Einstein College of Medicine in New York and lead author of the report, published Monday in the Proceedings of the National Academy of Sciences.

"Jews tend to be more related to one another than they are to non-Jews, including non-Jews living nearby it's true in every region," he said.

Ostrer's earlier work had mainly focused on DNA samples collected from American Jews. Hoping to "catch up" and present a more complete picture of Jewish history and diversity, he and his colleagues analyzed DNA samples from 145 people of North African Jewish origin from Morocco, Algeria, Tunisia, Djerba (an island off the Tunisian coast) and Libya.

Comparing the collected DNA with genetic data from a variety of other Jewish and non-Jewish groups, they found that the North African populations clearly had genetic patterns more similar to European and Middle Eastern Jews than non-Jewish people currently living in the region. The data indicate that, once established in their communities, Jews in this region did not often intermarry with non-Jewish neighbors.

The scientists also saw that North African Jews formed two major subgroups: Moroccan and Algerian Jews shared more DNA with European Jews than was seen for Tunisian, Djerban and Libyan Jews.

This is probably because Jews living in Western Africa intermarried with Sephardic Jews who fled there after their expulsion from Spain and Portugal in the late 15th century, the researchers wrote.

Yeshiva University historian Lawrence Schiffman said the results lined up nicely with the historical record.

"It's exciting to see that what we know from the history books is turning out to be real in the genetics," he said.

A Waikato farmer is demanding compensation after a genetic mutation in a commercial breeding bull created unusually hairy calves that are getting into water troughs to cool off.

The organisation that provided the bull semen, Hamilton-based dairy genetics company Livestock Improvement (LIC), said it would not pay compensation as the genetic mutation is ''naturally occurring'', meaning it did not result from anything LIC did.

If it was liable and did pay compensation, LIC says it could be exposed for nearly $2 million.

South Waikato farmer Craig Littin is one of about 900 affected farmers nationwide, including about 400 farmers in the Waikato. About 1500 calves, all heifers, are understood to be affected, as carriers of the genetic mutation.

Littin said he had 10 defective calves bred from semen bought from LIC.

The defective semen is from a holstein-friesian bull called Matrix, by a holstein-friesian sire called Halcyon.

"The Matrix calves have come out really funny. They are extremely hairy and are doing really strange things, like sitting in water troughs to try and control their body temperature," Littin said.

The Lichfield dairy farmer, who runs a cross-bred herd, said LIC should pay him full compensation for the defective animals.

LIC confirmed there was a genetic mutation in Matrix, inherited from its sire, which has affected about half the female calves bred from the Matrix semen.

LIC also confirmed the traits from the mutation, which include excessive hairiness and a lack of heat tolerance. It has received about 40 complaints from farmers.

Interleukin Genetics, Inc. Announces Conference Call to Discuss Second Quarter 2012 Results

In an effort to get FDA approval for a new cancer therapy, pharmaceutical giant Novartis is teaming with the University of Pennsylvania and investing at least $20 million in a new center to expand the university's work.

The collaboration between Novartis and Penn is expected to start in the fall with a new research and development facility, the Center for Advanced Cellular Therapies, to be established within the next year. The center's location has not yet been determined but will most likely be on Penn's campus, university officials said Sunday.

The partnership comes after a Penn team led by immunologist and gene-therapy pioneer Carl June published work last year in two major journals showing that it had genetically engineered patients' T cells - the big guns of the immune system - to recognize and attack the malignant cells of chronic lymphocytic leukemia, and then stand guard against the disease.

Although only three patients who had failed standard therapies were treated with the designer T cells, all three went into lengthy remission. Never before in published experiments had engineered T cells multiplied - and then persisted - enough to be so effective in patients.

David Strayer, a professor of pathology at Thomas Jefferson University who has long studied gene therapy, said the Penn and Novartis agreement comes "at a time when research funding is quite difficult to garner."

The partnership is an "encouraging sign" that large pharmaceutical companies are willing to team with medical schools.

"This could be the tip of the iceberg in pharmaceutical companies' having an interest in products being designed and developed by medical schools," Strayer said.

For all their sophistication, the designer T cells - with what scientists call chimeric antigen receptors (CAR) - remain experimental. The new T cells kill both healthy and cancerous B cells, so patients' supply can be permanently depleted.

B cells, which help fight viral and bacterial infections, are not indispensable to the body. But patients who lack B cells need regular intravenous doses of immunoglobulins to reduce their chances of infection.

In an editorial in the New England Journal of Medicine, two oncologists, who called the results of the new study impressive, also warned that toxic effects, known and unknown, "could pose substantial problems."

The genetics research group led by Professor Hannes Lohi, based at the University of Helsinki and the Folkhlsan Research Center, has, in collaboration with Adjunct Professor Kirsi Sainio's research group, discovered the cause of a life-threatening skeletal disorder affecting Brazilian Terriers. The disease is caused by a mutation in the GUSB gene. Malfunction of the GUSB gene has previously been linked to a severe skeletal disorder in humans, called type VII mucopolysaccharidosis (MPS VII).

The gene discovery is yet another example of a shared disease heritage between dogs and humans. Based on this study a gene test has been developed for the breed to eliminate the disease.

The study has been published in PLoS ONE journal on July 5, 2012.

Bone abnormalities are common in a group of lysosomal storage diseases, also known as mucopolysaccharidosis (MPS). Lysosomes are microscopic intracellular organelles that consist of more than 40 different degradative enzymes. They function as a cellular "cleaning system" and are responsible for example digesting foreign bacteria in the cells and destroying damaged cellular components. Functional defects in the lysosomal enzymes lead to the accumulation of a particular structural component, glycoaminoglycan, in the lysosomes, and this in turn leads to the development of skeletal disorders known as mucopolysaccharidoses.

Eleven different MPS diseases have already been found in humans. Typical features of the disease include dwarfism, skeletal abnormalities, coarse facial features, cloudy corneas and overgrowth of the internal organs.

Dogs are known for extreme structural variation, and some of these features have been intentionally bred. For example, the length of the limbs varies greatly between breeds. Besides breed-specific particularities, dogs also have serious inherited skeletal disorders, the genetic backgrounds of which are now being discovered.

The diagnosis of the skeletal disorder in Brazilian Terriers confirmed by gene discovery

A few years ago our research group was introduced to Brazilian Terrier puppies that had severe congenital skeletal abnormalities in the limbs, loose joints, facial deformities and dwarfism. The affected puppies could not move and had to be put down before the second month of life.

WALTHAM, Mass.--(BUSINESS WIRE)--

Interleukin Genetics, Inc. (ILIU) announced today that the Company has received top line results from the Periodontal Disease Prevention Study (PDPS) being conducted by the University of Michigan School of Dentistry. The preliminary results indicate that in Low Risk patients, there was no significant difference between two dental preventive visits per year and one preventive visit per year in reducing the percentage of patients who had tooth extractions over the 16 year monitoring period; 13.8% versus 16.4% (p=0.092 ns). In addition, results indicate that in High Risk patients, two preventive visits per year significantly reduced the percentage of patients who had extractions over a 16 year monitoring period compared to one preventive visit per year; 16.9% vs. 22.1% (p=0.002). There was also a positive relationship between number of risk factors and the percentage of patients with extractions (p<0.001). The Low Risk population (approximately 47% of the study) was defined as non-smokers, genetically negative per the Companys PST test and no history of diabetes. High Risk patients were defined as having one or more risk factors, i.e. PST positive, diabetes or smoking.

For more than 50 years, adult patients have been advised to visit the dentist every six months for an examination and cleaning. However, the data from this study appears to question the every six months, one-size-fits-all model for preventive dental visits for adults in a low risk population, said Lewis H. Bender, Chief Executive Officer of Interleukin Genetics. These results support movement towards more personalized preventive measures for the management of periodontal disease in low risk individuals, while encouraging more preventive care in high risk patients.

The PDPS was led by William Giannobile, D.D.S., D.Med.Sc., Director of the Michigan Center for Oral Health Research and Chair of the Department of Periodontics and Oral Medicine at the University of Michigan School of Dentistry, and enrolled approximately 5,400 consenting adults. Patients were identified through a large dental claims database with more than 16 consecutive years of documented oral health history.Participants provided a DNA sample and information on other risk factors to allow them to be classified as either Low Risk or High Risk for periodontitis development. The PST Genetic Test identifies individuals with increased risk for severe and progressive periodontal disease and significant tooth loss based on a proprietary panel of genetic variations that predispose an individual to over-express inflammation. Investigators intend to seek to publish the study results as soon as possible.

Approximately 8 to 15 percent of adult Americans have moderate to severe periodontitis, which, if not diagnosed early and treated properly, can lead to tooth loss, and major changes in appearance. In addition, clinical studies have associated severe periodontal disease with increased risk for heart attacks, strokes and other systemic diseases. Multiple studies have shown that a small number of risk factors, including smoking, diabetes and genetics, are responsible for much of the differences among patients in the severity and progression of periodontal disease. This study was funded by Renaissance Health Service Corporation, a nonprofit organization focused on the advancement of oral health.

About Periodontal Disease and Oral Health Care

According to the American Academy of Periodontology, periodontitis (gum disease) is a chronic inflammatory disease initiated by bacterial accumulations on the teeth. If untreated, or inadequately treated, periodontitis destroys the bone and soft tissues that support the teeth and ultimately leads to tooth loss. Although bacteria are essential for initiating periodontitis, the severity of disease and response to treatment is the result of disease modifying factors including smoking, diabetes, and genetics. Multiple studies have shown that genetic factors are responsible for more than 50 percent of the differences among patients in the severity of periodontal disease.Recent studies link periodontitis with diabetes, heart disease, stroke, premature births, and low-weight births. According to information from the Center for Disease Control and Prevention, one-fourth of U.S. adults aged 60 and older have lost all of their teeth.In 2009, an estimated $102 billion was spent on dental services in the United States, and each year Americans make about 500 million visits to dentists.

Philadelphia, PA, August 6, 2012 Individuals with mutations in BRCA1 and BRCA2 genes have a significantly higher risk of developing breast and ovarian cancers. Families at risk have been seeking genetic testing and counseling based on their mutation carrier status, but the standard method of direct sequencing is labor-intensive, costly, and it only targets a part of the BRCA1 and BRCA2 genes. A group of Canadian scientists has developed a new sequencing approach to provide a more effective method of BRCA1/2 mutational analysis. Their work is published in the September issue of The Journal of Molecular Diagnostics.

"A comprehensive understanding of BRCA1/2 genotypes and the associated tumor phenotypes is needed to establish targeted therapies," notes lead investigator Hilmi Ozcelik, PhD, of the Fred A. Litwin Centre for Cancer Genetics, Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada. "Recent studies have suggested that certain chemical inhibitors are effective for the treatment of breast cancer in patients with BRCA1/2 mutations. Therefore, availability of new, affordable, and comprehensive technologies to screen for these mutations will be critical to identify patient-candidates for targeted therapies."

The investigators used a technique called long range PCR to generate amplified BRCA1/2 fragments, known as amplicons, from the DNA of 12 familial breast cancer patients. The amplicons were screened using deep sequencing, also known as Next Generation Sequencing (NGS), which allows for the simultaneous screening of millions of DNA molecules, thereby dramatically increasing speed and throughput. While conventional screening methods target only the exons of BRCA1/2, deep sequencing can screen the entire genomic region, including introns and untranslated regions. The specimens had been previously analyzed using conventional methods, allowing for a comparison of results.

In addition to identifying one genetic variant that was missed due to human error, the new method successfully identified all of the expected BRCA1/2 variants. They identified both exonic and exon/intron boundary variants. The test was done at a very low cost, and with a turnaround time of 12 days. "One of the key advantages of workflow of long-range PCR is the ability to visually detect large genomic duplications, deletions, and insertions," notes Dr. Ozcelik. "When combined with next generation sequencing, long range PCR can be a powerful tool in the detection of BRCA variants in the clinical setting. Our method confirmed the presence of variants with very high accuracy, and without false-positive results."

Long-range PCR and next generation sequencing identified a wide range of intronic BRCA1/2 variants, both commonly occurring and rare, that individually or in combination may impact BRCA1/2 function. Dr. Ozcelik notes that despite a small sample size, the data shows great variability in the number, type, and frequency of variants that can be identified from familial breast cancer patients.

"Our challenge now is to establish analytical methods that systematically investigate this more comprehensive data in order to provide better risk information for clinical management of the disease," says Dr. Ozcelik. "Given the extensive level of genetic information acquired from each patient, profiles can be constructed in breast cancer patients compared to population controls to produce a more effective means of generating BRCA1/2-associated risk to the individuals and their families.

Brazil is using genetic engineering to help fight dengue fever, creating mosquitoes whose offspring die before they mature. Tests in two towns have been successful - but are there ecological implications?

Dengue is a tropical fever with similar symptoms to the flu: feverand shivering, headache and joint pain, and a rash. Most infections are comparatively mild and last no longerthan a week.

But every year there are around half a millionserious cases,some of which prove fatal.The disease hasspread considerably in recent years. Even Europe is no longer safe. In 2010, more than 600 travellers returning to Europe from abroadwere diagnosed with dengue fever. "The number of unreported cases is estimated to be farhigher," says Jonas Schmidt-Chanasit from the Bernhard Nocht Institute for Tropical Medicine in Hamburg."We believe it could be ten times as many."2010 alsosaw the very first cases of infection in France and Croatia.

The root of the problem

Aedes aegypti, the mosquito's scientific name,has a black and white patternand is actually quite pretty, as insects go. Butit can carry andtransmit several viruses. It's one of the maincarriers of yellow fever, and for humans it can be disastrous. In the Spanish-American War of 1898, the number of US soldiers who diedof this kind of infectious diseaseis believed to have beenhigher than the number killed in battle. There is nowa vaccine against yellow fever, but none has yet been foundto preventdengue fever.

Fertile breeding ground for mosquitoes: a teaspoonful of standing water is enough

All attempts to fight the mosquitoes with the help of insecticide have failed. In Brazil, awareness campaigns warn peoplenot leavecar tires lying around where rain can collect inside them, and toflush toiletsregularly, even if they're not beingused.Thedangerous larvae generally breed in standing water,which people are advised to avoid - but the mosquitoes can also breed ina puddle, a hollow in a rock, or eventheheart ofa flower.A teaspoon of water isallthey needin order to deposittheir eggs.

Assistance fromgenetic engineering

British scientistswith the company Oxitec have now developed a genetically-modified male mosquito whose offspringare unable to survive into adulthood. The idea is that the genetically-modifiedmalesarereleased intoa natural environmentandallowed tomate with female mosquitoes. The fertilized eggs developinto larvae or pupae, andthen die.

Oxitec hasconducted successfulfield trials on the Cayman Islands and in Malaysia. In 2011, the biotech company Moscamed in the Brazilian city of Juazeiro joined the project. Here, in the hinterland of Brazil's Bahia state, dengue is more common than almost anywhere else in the world.

Bone marrow from his hips was used in the treatment and Curry told Gutierrez that it is the only thing hes tried that has helped him feel better. Curry is still working out on the side during Raiders practices and said hell only return to practice when hes fully able to help the Raiders.

My goal is to get healthy and just go out there and be violent, be fast, be a pain in the offenses butt and whatever I have to do on the defense, do it, Curry said. And do it full speed. I cant do that until my body says its ready.

The treatment has been popular with Oakland athletes. Linebacker Rolando McClain said that the treatment helped his legs feel better earlier this offseason and As pitcher Bartolo Colon has credited stem cell treatment on his shoulder with saving his baseball career.

With McClain facing a possible suspension under the Personal Conduct Policy and Oakland short on linebacking depth, the Raiders need Curry to be healthy for the start of the season.

Hamish McMillan bee gene's tests won him the best of fair award at the Otago Science and Technology Fair. Photo by Craig Baxter.

It was his father David's work in honey production that prompted the study looking at the complementary sex determiner, or CSD, in bees.

Hamish (17), a year 13 pupil at John McGlashan College, said as varroa was moving throughout New Zealand, including Otago, he wondered what would be lost if the feral or wild populations of bees were wiped out.

Testing both feral and managed populations, he found the majority of genes to be individual to each type of bee.

"As varroa moves through, it will kill off the feral hives and we'll lose that diversity."

The effect would be lower hive population numbers as hives became more vulnerable to disease and varroa.

"It will weaken the hives and lower the honey production."

He was looking at medical research as a career and planned to attend the University of Otago next year.

A total of 285 exhibits from 25 schools in Dunedin and Otago were submitted to the fair.

A GROWING number of overseas clinics touting stem cell therapy for conditions ranging from sexual disorders to HIV are targeting Australia, where such treatments are restricted.

Australian scientists have raised concerns about so-called ''stem cell tourism'', saying many of the treatments offered are unproven, untested and potentially deadly.

The Swiss firm Fetal Cell Technologies International has been advertising in Australia since last year and Emcell, based in Ukraine, started promoting its services last month.

It is estimated as many as 200 Australians have travelled overseas for the therapy. The secretary for science policy at the Australian Academy of Science, Bob Williamson, said he empathised with the desperation of seriously ill people but warned against the unproven therapies, which can cost up to $60,000.

''The therapies are almost all untested and unproven and sometimes they have killed people,'' Professor Williamson said. The Sun-Herald's calls to Emcell's Melbourne office were not returned.

Stem Cells Australia's Megan Munsie, who is conducting a study into stem cell tourism with Monash University, said many people she interviewed were unaware of the risks of therapy overseas.

''We're not talking about rubbing something into your skin or taking a capsule, we are talking about often a very invasive procedure,'' she said.
