Fischer, the reigning Missouri Valley Conference champion, qualified for the NCAA field with a seventh-place finish at the NCAA Midwest Regional on Friday, Nov. 11. Story Links Of the 12 Bulldogs that competed at the NCAA Midwest Regional, nine were either freshman or sophomores and eight were competing in their first NCAA Regional competitions.   NCAA Midwest RegionalNov. 11, 2016 – Iowa City IowaAshton Cross Country Course As a team, the Drake men’s squad finished 20th out of the 33 teams that entered runners in the competition and ahead of the likes of DePaul, Creighton, SIU and UNI. The extremely young Drake women’s team, led again by Bailee Cofer (Overland Park, Kan.) finished 32nd in the field of nearly 40 teams. Cofer finished in the top half of the competition in 114th place for the Bulldogs. “Both teams are very young and they competed well today,” Hostager added. “That will provide some great momentum, not just for next season, but for the upcoming track season. I’m very proud of how hard they’ve worked all fall and there weren’t too many MVC teams ahead of us today, which bodes well for our future.” “Reed ran an excellent tactical race,” said Drake head coach Dan Hostager. “He’s put a lot of work into making it to NCAAs so it was great to see it happen against some of the nation’s best. There’s definitely more left to be done as his goal has always been to do well at NCAAs. So he won’t be satisfied just getting there and achieving this tremendous accomplishment in of itself.” Drake Individual Women’s Results6k – 235 runners114. Bailee Cofer, 22:06.5196.

New method tags breast implants with tomato DNA to prevent counterfeiting

first_imgAug 2 2018For years, a French company sold breast implants made of cheap industrial silicone components. Headline news when it broke in 2010, this scandal is still keeping the courts busy today. Now, a research team at the Fraunhofer Institute for Applied Polymer Research IAP has come up with a method to prevent this sort of fraud. It gives manufacturers the opportunity to counterfeit-proof implants – by tagging them with encapsulated tomato DNA.With business going global, product counterfeiting has become a growing problem for manufacturers. Consumers are at risk when counterfeiters set their sights on sensitive products such as medical equipment and drugs. Fakes are usually inferior. They can seriously harm patients’ health and even jeopardize lives, as the scandal surrounding a French breast implant manufacturer goes to show. The company cut corners, blending in unapproved silicones to slash production costs (more on this in the box “How breast implants are made”).This kind of illegal manipulation is almost untraceable. It takes elaborate analyses to detect such tampering. “Counterfeiters generally buy high-quality individual components from reputable suppliers and stretch them with cheap silicone, which costs a fraction of the premium material. Product pirates turn huge profits,” says Dr. Joachim Storsberg, a scientist at the Fraunhofer IAP in Potsdam and an expert witness in court cases centered on breast implants. A method to substantiate both quantitative and qualitative manipulations of one or more components would be ideal.Zero chances of product piracyStorsberg and his team – which includes Marina Volkert from Berlin’s Beuth University of Applied Sciences – developed precisely this type of procedure. It has already been patented. The idea is to use DNA sequences as permanent markers to positively identify implants. This gives manufacturers the opportunity to tag products with a counterfeit-proof marker and thereby enhance patient safety. The source material is sure to raise eyebrows: tomato DNA makes the perfect marker, as various experiments have substantiated. “We isolated genomic DNA (gDNA) from tomato leaves and embedded it in the silicone matrix. We used approved siloxanes, which are building blocks for silicone products, to manufacture breast implants,” explains Storsberg. The researchers managed to demonstrate the extracted DNA’s temperature stability in pilot experiments. They vulcanized the gDNA in the host silicone at 150 degrees for five hours and then tested it with a polymerase chain reaction (PCR), a technique to amplify DNA, and with a special analytical method call gel electrophoresis. The DNA remained stable and did not degrade.”Breast implants are made up of components; that is, several silicone polymers that cross-link to form a gel. The components’ manufacturer now has the option of marking silicones with the encapsulated tomato DNA sequence during the production process. He alone knows the type and concentration of the DNA used. The components are marked first, and then sold to the implant manufacturer. The PCR method can detect if the manufacturer stretched components with inferior materials or used a lower concentration. “This works much like a paternity test,” says Storsberg. The advantage of tomato DNA is that it costs next to nothing and is suitable as a counterfeit-proof marker for many polymer-based implants such lens implants.​ Source:https://www.fraunhofer.de/en/press/research-news/2018/august/marking-breast-implants-with-tomato-DNA-to-prevent-counterfeiting.htmllast_img read more
