Nanocellulose Study

first_imgUniversity of Georgia food engineer Fanbin Kong has been awarded a more than $496,000 grant from the U.S. Department of Agriculture National Institute of Food and Agriculture to study the safety of nanocellulose and how it affects humans’ food digestion and nutrient absorption.Nanocellulose is a light, solid substance obtained from plant matter, generally wood pulp. It is currently used in the food industry as a stabilizing agent, a functional food ingredient and in food packaging production.“Nanocellulose has big application potential. It could be added to packaging materials to strengthen them or added to food as a dietary fiber. It also greatly increases the viscosity of foods,” said Kong, a researcher in the UGA College of Agricultural and Environmental Sciences Department of Food Science and Technology. “We now have the technology to break down cellulose (down) to a nanoscale size, called ‘nanocellulose,’ with a diameter of 1/100 nanometers. In comparison, human hair is about 80,000 nanometers in diameter.” Scientists know the benefits of nanocellulose, but they don’t know how it behaves in the digestive system once it’s ingested. “For example, will the very tiny particles easily penetrate into cells and tissues of the human body and become a big health concern? Will the particles remain nanoscale or will they aggregate together to increase the particle size? Will they bind to proteins, carbohydrates or enzymes and make food digestion difficult, reducing nutrient absorption? Will they impact the composition of the microorganisms that live in human digestive tracts (called ‘gut microbiota’)?” Kong said.These are the questions Kong hopes to answer with the USDA three-year grant. For his work at UGA, Kong developed models of the human stomach and intestine that realistically demonstrate the way food breaks down in the human body. These models help him test the effectiveness of functional foods and develop new foods aimed at helping those with specific health issues.“At UGA, we will use the artificial stomach and intestine models to study how the nanocellulose will transform its size and shape in the digestive tract, and how it will interact with protein, lipid and starch molecules (to) affect (the protein, lipid and starch molecules’) digestibility,” Kong said. He will collaborate with scientists at the University of Missouri who will conduct cell tests to determine whether or not the nanofibers can penetrate into intestinal cells and how they will impact the gut microflora. Tailiang Guo, a toxicologist with the UGA College of Veterinary Medicine, will use mice to validate the results from the simulation test, including examining any toxic effects caused by eating food containing nanocellulose.“Macroscale or microscale biomaterials are generally recognized as safe and do not pose health risks to consumers. However, the biological effects and toxicity of nanoscale biomaterials cannot be predicted solely from their chemical structures,” Kong said. “This project will fill the knowledge gap about the behavior of nanocellulose during digestion and reveal any toxic effects.”Kong’s grant funds are part of a $5.2 million investment awarded in support of nanotechnology research at 11 universities. Collectively, these projects will shed light on ways nanotechnology can be used to improve food safety, enhance renewable fuels, increase crop yields, manage agricultural pests and more. The funds were made available through the USDA Agriculture and Food Research Initiative, the nation’s premier competitive, peer-reviewed grants program for fundamental and applied agricultural sciences.“This important grant will allow Dr. Kong to continue his long-term work to help us better understand how nanobiomaterials impact human, livestock and environmental health,” said Robert N. Shulstad, CAES associate dean for research. “This vital work will further our quest to provide a safe food supply for the nation and beyond.”(Merritt Melancon, public relations coordinator in the UGA College of Agricultural and Environmental Sciences, contributed to this article.)last_img read more

Bent Creek and Dupont Singletrack Closed: Stay Off The Trails

first_img What’s one ride going to hurt?I spoke with Jeff Keener, head of the Pisgah Area SORBA to get his input on riding muddy trails, “Once you get two to three inches of mud, it’s a hell of a lot of work to repair,” says Keener. “What most people don’t realize that it takes hundreds of man-hours and volunteers to fix the damage.”It goes without saying, but when Keener and his team are working to fix these trails, they aren’t riding. This means you won’t be riding either. Why? Because the same conditions that are perfect for riding are perfect for trail maintenance.So lets weigh the pros and cons here. Squeeze in a ride when it’s crappy and have the trail closed during the good weather for repair? Or would you rather sit out the rain and ride when it’s beautiful outside?According to Keener, some of the trails in Bent Creek are in the worst condition he’s seen in over a decade. “I could not believe the number of people that were riding. It was packed,” says Keener. “This is the first time in don’t know how many years that it’s been closed.”Give Back To Your TrailsThe easiest and best thing you can do is to stick to the gravel when it’s wet and muddy. Want to get involved and help improve your local trails? Then get out and volunteer! Look up your local SORBA group to spend some quality time in the woods, meet some great folks, and help maintain the singletrack you love.See you on the trails (when it’s dry).Justin Forrest is an outdoor writer, fly fishing addict, and co-founder of Narrative North—based in Asheville, N.C. He posts pictures of cats and fishing on Instagram sometimes. Due to the excessive amount of rain in WNC, Bent Creek Experimental Forest and Dupont State Forest are closing singletrack trails until Friday, June 1, to prevent further damage.Both forests are keeping gravel roads/forest roads open, but encourage users to be careful due to slippery conditions. Cars are encouraged to take it easy on forest roads to prevent ruts from developing.In a press release issued by the Pisgah Ranger District, “We’ve had some pretty bad soil erosion so far and we need the public’s help to protect these trails by staying off them when they’re this vulnerable to damage,” said District Ranger Dave Casey. He added, “It will take a few days for the trails to dry out and stabilize before they can handle the number of visitors we usually see in Bent Creek.”  The N.C. Forest Service issued a similar release on Tuesday, May 29, stating that “Saturated trail surfaces will be muddy and foot traffic, bicycles, and equestrian users will cause erosion issues and the trails to become rutted. There will be temporary closures of all DSRF singletrack trails.”Other forests in the area are suffering from the above average rainfall as well. Trail systems across Georgia and South Carolina are closing due to the wet and muddy conditions. The Green River Games has organized a trail restoration weekend in the Green River Gamelands, just outside of Saluda, N.C. They haven’t seen weather like this in over a hundred years, with mudslides completely decimating some of the trails.But I came to send it on some epic downhill bro!Whether you live here full time or are traveling here to ride, stay off the singletrack when it’s wet and muddy. We’re fortunate to have amazing volunteer groups who maintain our trails, but this only makes their work harder. Selfishness for one muddy session can ruin trails for countless others. If you see someone heading out into closed trails, contact an official. They will be happy to teach them a thing or two.If you’re caught on closed trails, you will get a hefty fine, which could’ve gone towards some new components or a new bike. That’d put a pretty huge damper on future riding. To report issues or trail misuse at Dupont State Recreational Forest, contact them at (828) 877-6527. For Bent Creek, Contact the Pisgah Ranger District at (828) 877-3265.last_img read more

8 signs you have a credit card problem

first_img 17SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr by: Kimberly J. Howard, AdviceIQCredit troubles often begin inconspicuously, yet there are signs all along the way before they become unmanageable. Being alert to these warnings allows you to make the necessary changes to prevent a future of financial worries.Having a credit card isn’t bad when you use it for the right reasons. It serves as a bridge to better things and establishes a credit history, which helps you make big purchases such as a home or a car.Unfortunately, the “spend first, pay later” option is a slippery slope that leads to serious credit problems. They can happen to people of every age, income level and social status.Many signs are obvious to conscientious consumers, but life can sometimes become so hectic that you push them aside for later. Only later never comes.The sooner you admit that you have credit problems, the sooner you are able to fix them. Neglect the issue and you may end up with accounts in collections, purchases repossessed, eviction and bankruptcy. continue reading »last_img read more

Inaugural CENTER Stage Awards & Gala Raises $80K

first_imgSubmitted by The Washington Center for the Performing ArtsThe Washington Center for the Performing Arts hosted its inaugural CENTER Stage Awards & Gala on Thursday, July 28. The format of the event was kept under tight wraps, and the 175 guests attending were treated to an element of surprise when they entered the main theater to find the stage had been extended over the entire orchestra (lower) level, to create a ballroom-type atmosphere. The event featured Steve Bean as auctioneer and Cheryl Selby as emcee, and included a cocktail hour, full dinner catered by Pelligrino’s, an awards ceremony, and live auction.Studio One dancers were among the performers at the Gala. Photo credit: Kathy Strauss MediaGuests were entertained throughout the evening by performances by organist Sharon Stearnes on the Andy Crow Wurlitzer organ, a beautiful ballet duet by Ballet Northwest, dancers from Studio West, a dazzling acro-dance performance by Studio One, and the evening was kicked off by Masterworks Choral Ensemble. Jill Barnes, Executive Director, said, “The entire evening was spectacular, and we were honored to showcase the incredible artistic talent in the community.” Barnes added, “Not only did Masterworks perform to welcome the guests into the theater, many of them stayed and volunteered after their performance!”The Washington Center provided two awards for Excellence in the Arts. The Commitment to the Arts award was given posthumously to Andy Crow, who passed away earlier this month and had given so much during his lifetime to music education and restoring organs. The Achievement in the Arts award was given to Bud and Mary Johansen who started the Johansen School of Dance in Olympia and trained students in ballet for over 40 years. “We were so delighted to award Bud and Mary Johansen and honor Andy Crow,” says Barnes. “The awards were heartwarming and meaningful.”Bud and Mary Johansen were honored for their extensive contributions to the arts in our area. Photo credit: Kathy Strauss MediaOverall, the event raised $80,000, including funds to overhaul and upgrade a system which assists patrons with hearing loss. “We are delighted to have raised enough to immediately begin expanding our assisted listening program. We were touched to have such outstanding support from donors, especially Panorama, in making this a reality. Panorama understands the importance of keeping those with hearing loss active and engaged, and we are honored to have their support.”The Washington Center’s goal is to have the new system installed by October. “With the help from so many donors, we’re looking forward to proving this additional level of accessibility for patrons,” says Barnes. “We are looking forward to – and have already started – planning an equally spectacular awards and fundraising gala for next year.” Facebook74Tweet0Pin0last_img read more
