Chinese scientists make nano "Trojan horse"magic pass disney to strangle tumorsTake A One Day Mini Summer Vacation In Chicago"s Millennium Park I like to visit with my friends and I like to cook and when I put these two things together it is called a party. I have never thought of myself as an event planner but I do love to plan parties at my home and I have become quite efficient at it. Trust me I am no Martha Stewart and lets face it most of us are not. The important thing is do what you love. If you want a theme party do it, and if you want an intimate dinner then have at it. You are in the driver"s seat. The important piece is to plan. Never be afraid of too much planning but do not let the planning take away the fun. Stay flexible. If you enjoy music why not head for a bandshell or other outdoor festival wristbands. If you love to dance you could hit the local clubs, or find a band or artist around the town that you haven"t yet heard. Many restaurants also offer entertainment in their bar areas. Change the music that you listen to, get out and experience many different types of music; jazz, blues, long-hair, big band, singer-songerwriter, pop, rock....keep it interesting. Never the same work out twice. I like to switch things up every time I exercise. You may do some of the same basic exercise, just tweaked each time, or opt for a completely different work out every time. Need ideas? Google has got you covered here! Just do something sport wristbands else Can"t run for a few weeks because of a knee injury? Swim, do yoga, work on your balance and flexibility, walk your dog more often. "Can"t" make it to the gym or your exercise classes because of a change in your schedule? Do something different at home - borrow some new exercise DVDs from a friend, or sign some out from the library. Try something new. Summary: Vans Warped Tour definitely peaks the summer festivals with a staggering 63 acts signed up to perform at Invesco Field. Tickets are still available, and they are general admission prices. Since this festival has more bands packed into one day, I would suggest staying up to date on the main website, and getting a schedule as soon as possible. Choose the bands you simply must-see, and plan out the day before you hit the road, this will ensure a better experience. My first sales were at TAMUCC at a small open art festival event wristbands. Very low-key but sold all my little ink drawings and cards I created for 5 bucks a pop I was stoked... being a poor college woman. Word of mouth is effective and I have enhanced this with having professional business cards to help with referrals. When hosting a Swap Party, be sure to briefly explain in the invitation what it is and what type of items are to be brought. Also be sure to explain that all items must be or look new, and be in good condition. Each person may take home with them the same number of items as they bring. The Muggs take the stage at 11:30 p.m. on Saturday at Cadieux Cafe with guests The Robin Moore Band on at 10:00 p.m. But if you know the Cafe, arrive early for Detroit"s best Belgian food and plenty of beverages on tap.
BEIJING -- Chinese scientists have folded DNA molecules in an origami-like process to make a nano "Trojan horse", which is thinner than 1/4000 of a hair and can release "killers" to fight cancer tumors.
Cancer cells need a lot of nutrition to multiply, but they don"t produce nutrient substances, said lead researcher Nie Guangjun, of China"s National Center for Nanoscience and Technology (NCNST).
All the blood, oxygen and energy are conveyed to cancer cells through blood vessels, so many scientists are trying to create blocks on the blood vessels feeding tumors.
Through precision control, researcher Ding Baoquan folded a single-strand DNA of a phage (a type of virus) into a rectangular sheet. Then he put four "killers" -- molecules of thrombin (a clotting enzyme in blood plasma) -- on the sheet and rolled them up.
At the interface, "locks" made by fragments of nucleolin protein DNA were installed, forming a tube-shaped nano "Trojan horse" or nanorobot, which is 90 nanometers long and has a diameter of 19 nanometers.
After injection, the "Trojan horse" travels in blood vessels and only tumors have the "key" to open the "locks." Once unlocked, the killer thrombin molecules are released, attracting platelets and fibrinogen protein to form a large thrombus, or clot, in the blood vessel within hours to cut off the blood supply and "starve" the tumor to death, Nie said.
The nanorobot can be cleared out of the body after it has finished its task.
Researchers have conducted controlled experiments on more than 200 mice with melanoma, breast cancer, ovarian cancer and primary lung cancer, and found the nanorobots are effective in strangling the tumors, Nie said.
In one experiment on eight mice with melanoma, the tumors in three mice totally disappeared. The average survival life of the mice was prolonged from 20.5 days to 45 days. No metastasis was found, according to Nie.
The incidence of malignant tumors has been rising in China in recent years, becoming a major health threat. Interventional embolization therapy has become the first therapeutic choice for patients with advanced liver cancer. About 600,000 to 800,000 Chinese with liver cancer receive interventional therapy every year.
However, patients face anesthetic risks in this therapy and doctors face exposure to X-ray radiation, so a safer, more effective and convenient treatment is a priority, and nanotechnology has opened new opportunities, Nie said.
The research began five years ago, when NCNST researchers first looked at cutting off the tumor blood supply by using DNA-based nano carriers.
Shi Quanwei, another member of the research team, said laboratory verification of the nanorobot idea has been completed, but industrial production and application of the nanorobot is still a long way off.
"We hope to attract investment to improve the production technique and enlarge the manufacturing scale of the nanorobot, and conduct further research on its effect and safety before application for clinical trials," Shi said.
"We need to make breakthroughs on technical bottlenecks, and hope to transform the basic research into practical therapy to benefit patients with tumors."
The research was recently selected as one of 30 winning projects at a contest of innovative future technologies in Shenzhen, South China"s Guangdong province. The contest encouraged young Chinese scientists to conceive groundbreaking technologies and trigger innovation.different rubber band braceletswristbands canadaorder rubber bracelets cheaphow to do rubber band braceletscheap silicone wristbands for fundraising
