Sequence data generated with NuGEN’s target enrichment technology can be processed in BaseSpace using new app to mark duplicates and perform quality trimming
San Carlos, CA -OCT. 6– NuGEN Technologies is pleased to announce that scientists and clinicians using its Ovation Target Enrichment System to prepare biologic samples for genomic analysis can now process resulting sequence data in BaseSpace–a cloud computing platform, hosted by Illumina, Inc.
“NuGEN’s new Ovation Target Enrichment System Data Processing Application will allow the large community of Illumina sequence platform users to further streamline the rapid and convenient workflow of our Ovation Target Enrichment System products,” said Alan Dance, VP of Marketing at NuGEN.
The Ovation Target Enrichment product line employs Single Primer Enrichment Technology (SPET), a novel approach for enrichment of genomic DNA targets or cDNA for RNA target regions. SPET products allow researchers and clinicians to quickly and accurately enrich biologic samples for sensitive detection of a wide range of genomic markers including mutations, SNPs, indels, gene fusions, alternately spliced transcripts and copy number variants.
The new NuGEN-application, published on BaseSpace on September 30, provides an intuitive user interface for uploading sequence data. The application performs quality trimming and probe trimming on the parsed data – removing data derived from bases with low sequencing quality scores and aligning high quality data to the UCSC human reference genome.
Subsequently, PCR duplicate reads created during the library amplification process are identified using a random N6 sequence, unique to the Ovation Target Enrichment System workflow positioned adjacent to the barcode index.
Output files from the Ovation Target Enrichment System Data Processing Application for BaseSpace include processed BAM files with PCR duplicates removed or marked, processed FASTQ files with duplicates removed, and UCSC bigWig tracks with duplicates removed for visualization using the UCSC human genome browser.

Despite environmental, cost and market concerns, fracking–the hydraulic extraction of natural gas from shale–is here to stay. That was the consensus of experts who spoke at the British Consulate in Boston on Dec 15 2011.
Sponsored by the British American Business Council and National Grid, the panel included moderator Daniel Goldman, executive vice president and chief financial officer of Great Point Energy; David Hobbes, chief energy strategist for the information/strategy firm IHS CERA; Dr. Elizabeth Kane, first secretary and head of the energy team at the British Embassy in Washington, DC, and Dr. Francis O’Sullivan, research engineer and executivedDirector of the Energy Sustainability Challenge Program, MIT Energy Initiative.
Hobbes described the complexity of shifting international energy markets–pointing out the need to include the costs of extraction and transportation of what otherwise appears to be a low-cost source of energy. He challenged as “shoddy” a recent Cornell University report that extracting natural gas from shale could do more to aggravate global warming than mining coal, and said that it is unfortunate that the study is being used as a basis for US shale extraction policy. He predicted, jokingly, that the UK will come up with “an even stupider policy,” because, as a friend to the US, his homeland “tries to make the US look good,” by comparison.
According to Kane, incentives to invest in shale gas extraction are limited in the UK because the Crown holds mineral rights, because most shale fields are located in densely populated areas (such as under London), and because England does not have the road structure needed to support the fracking industry. Fracking in England was temporarily halted after it was determined that the practice had caused two small earthquakes–but resumed after experts found it was unlikely to cause major quakes, she said. Environmental concerns remain, however; members of a group calling itself “frack off” have chained themselves to fracking equipment to keep it from being operated.
O’Sullivan explained that despite significant shale reserves, few fracking operations are currently profitable because extraction costs are relatively high–but that this will change as technology improves. Regarding environmental concerns, he said it’s unlikely that chemicals used in fracking will leak from pipes into drinking water. In part, that’s because leaky pipes diminish wells’ performance , which provides the industry with incentives to make sure that fracking equipment and wells are tightly sealed. A greater concern is highly polluted “return” water. In Texas, he said, this water is injected into deep sealed aquifer but in Pennsylvania and Western New York State, which have different geologic underpinnings, companies must use other methods to prevent pollution.
O’Sullivan also pointed out that there’s shale to be mined in China, Australia and Argentina–and that the abundance of shale and the possibilities it presents as a source of relatively inexpensive fuel (compared with oil) will impact the global energy market in coming years.
Regarding future markets for natural gas, Hobbes said it’s not likely to be widely used for hybrid electric cars, which are expensive to produce and therefore not popular with consumers. He predicted that the market for shale gas will increase “in little bits and pieces over the next 20-30 years.” Over that period, energy consumption will go down, the US and Canada will add as much oil production as Iran possesses, and Chinese energy demands will optimize the market for natural gas producers in the US, he said.
O’Sullivan predicted growth markets for shale gas in commercial, residential, power, industrial and feed stock uses in the US and elsewhere, and– in light of the recent nuclear reactor failures–in Japan.

[Disclosure: please see below]
Two Forsyth Institute scientists and a Lexington, MA entrepreneur have launched PhotOral (TM)to develop and market the first consumer device using blue light to combat gum sisease.
Scientists Nikos Soukos, director of Forsyth’s Applied Molecular Photomedicine Laboratory and J. Max Goodson, senior member of the staff, found when testing the effectiveness of blue light in tooth whitening equipment, their patients’ gum health improved. They determined through research published in 2005 (see below) that such light can selectively kill pathogenic oral bacteria–without harming so-called “good bacteria” that exist in normal mouths–and began work on a device.
This year, Forsyth received a patent for the proposed blue-light treatment method; Soukos, Goodson and entrepreneur Stamatis Astra founded PhotOral; and, in September, PhotOral received an exclusive license from Forsyth to commercialize the technology.
The device will look “either like a mouth guard or a lollipop,” Soukos said.
It will work by shining certain light wavelengths onto the teeth, which act as mirrors to deliver the light to dental pockets between the teeth. Inserted into the mouth twice a day for 30-60 seconds, it should selectively target pathogenic bacteria and, as a cumulative effect, suppress them to prevent periodontal disease. It will not replace brushing or flossing–but, rather, will allow consumers an additional method for improving their oral health.
Most current consumer treatments–such as flossing, tooth brushing and antiseptics–seek to eliminate all sorts of the 700 bacteria found in the mouth, Soukos explained. But some of those bacteria are beneficial. “Our device aims to selectively target ‘bad bacteria’ in order to restore a healthy balance in the mouth.”
By doing so, the team hopes to help prevent or treat gingivitis, which occurs in 90% of adults, and periodontitis, which affects some 34% of adults in the US over 30. Severe periodontitis, which may be treated with medication, by scaling and planning or surgically, affects 13% of all adults. It can lead to loss of bone and teeth and is suggested as a risk factor for coronary based heart disease, atherosclerosis, pre-term births and chronic kidney disease.
Stamatis, the PhotOral CEO, said he is currently raising funds to support prototype production, clinical trials and marketing operations. “The potential market for the device is greater than $7B”
Soukos and Goodson’s research, published in the April, 2005 Journal of Antimicrobial Agents and Chemotherapy, suggested that light in the blue region of the visible spectrum might be useful in preventing, controlling or treating periodontitis-an oral infection that can lead to loss of bone and teeth.
Among the most destructive oral bacteria are the so-called “black-pigmented” bacteria (BPB), which are implicated as pathogens associated with periodontitis. Such bacteria accumulate black pigment consisting mainly of organic compounds called porphyrins . Some porphyrins are photosensitive and, when activated by light, induce a photodynamic reaction that kills the microorganism within seconds.
Before starting their research, Soukos and Goodson knew that other researchers had used lasers to deliver red or green light, which partially inactivated certain oral bacterial. The team also knew, from published reports, that porphyrins absorb blue light more readily than light that is red or green.
The Forsyth scientists employed a halogen lamp source commonly used for tooth whitening to shine broadband light composed mainly of blue and a small percentage of green light on pure cultures of BPB and on dental plaque samples obtained from individuals with chronic periodontitis. They found that the light rapidly killed BPB in pure cultures and that it selectively eliminated BPB in plaque samples containing 50o0-6000 different bacteria. They also found that certain species were more readily inactivated by the light than others and that varying the intensity and exposure time had different impacts on different bacterial species. The researchers concluded that intraoral light exposure can selectively reduce pathogens in dental plaque.
