Gold became popular items for cancer treatment,[url=http://duveticapiuminiitalia.webmium.com/][b]Duvetica Down Jackets[/b][/url]
cheap nfl jerseys Scientists are putting a modern spin on a cancer treatment that goes back to antiquity. It's heat therapy,[url=http://rogervivierflatsonline.albirank.net/][b]http://rogervivierflatsonline.albirank.net/[/b][/url], which is getting a new look with the help of microscopic particles of gold.
cheap nhl jerseys Cancer treatments usually involve powerful drugs or radiation,[url=http://monclerjackenoutletch.albirank.net/][b]Moncler Weste Billig Moncler Jacken Outlet Moncler Outlet Österreich[/b][/url]. But heating up the tumor - hyperthermia - can also be part of the therapy,[url=http://billigtmonclerdunjackastockholmrea.olimx.com/][b]Moncler Dunjacka Stockholm[/b][/url].
cheap mlb jerseys "Hyperthermia is an old technology . first recorded in papyrus by the Egyptians,[url=http://rogervivierflatsonline.albirank.net/][b]Roger Vivier Online Store[/b][/url], I believe. It's the first known treatment of breast cancer,[url=http://rogervivierflatsonline.albirank.net/][b]discount Roger Vivier Flats[/b][/url]," says Jeffrey Rosen of the Baylor College of Medicine in Texas.
"The idea is that as you raise temperature, you induce a heat shock in cells,[url=http://parajumpersoutletitalia.albirank.net/][b]parajumpers outlet italia[/b][/url], and that this makes them more susceptible to the damage caused by chemotherapy and radiation."
Rosen has just published new research on how some new materials can help harness the potential of hyperthermia for cancer treatment,[url=http://billigtmonclerdunjackastockholmrea.olimx.com/][b]Moncler Jacka Sverige Online[/b][/url].
cheap nba jerseys One problem in using heat against cancers is that it can damage surrounding,[url=http://giuseppezanottimenssneakers.webmium.com/][b]giuseppe zanotti sneakers men New Fall Winter 2013 Collection[/b][/url], healthy tissue. Rosen says that microscopic particles of gold - nanoparticles - can be injected into the body to make sure the heat gets to the right place.
"The gold nanoparticles have this ability to be activated by near-infrared lasers so that they can be heated quite rapidly,[url=http://woolricharcticparkaherenoutlet.olimx.com/][b]Woolrich Arctic Parka Heren Outlet[/b][/url]," he says.
And Rosen adds that the nanoparticles travel to where they're needed,[url=http://duveticaonlineitaly.albirank.net/][b]Duvetica italia[/b][/url], to the cancer,[url=http://monclerjackenoutletch.albirank.net/][b]http://monclerjackenoutletch.albirank.net/[/b][/url], so the healthy tissue doesn't get heated up.
"You'll have those gold nanoparticles actually accumulating in the leaky blood vessels of the tumor, and then the laser can be used locally just to heat that area."
In this study, the tumor was heated to 42 degrees for 20 minutes. The actual target was breast cancer stem cells,[url=http://monclerjackasverige.albirank.net/][b]Billigt Moncler Jacka[/b][/url], the cells from which cancers grow and metastasize,[url=http://duveticapiuminiitalia.webmium.com/][b]Duvetica Piumini Italia Outlet[/b][/url], and which tend to resist drug and radiation treatments.
Rosen says tests using laboratory mice suggest the heat treatments may be an effective way of augmenting radiation or chemotherapy for patients with some kinds of tumors, including breast cancer. But he cautions that it should not be considered a "magic bullet" in the fight against cancer.
authentic nfl jerseys "We think this is a proof of principle, that this type of approach will work,[url=http://parajumpersoutletitalia.albirank.net/][b]parajumpers Parka Piumini online shop[/b][/url], but it's a bit like the gene therapy field was maybe 15 years ago - we're going to have to still target to the right cells and the right place."相关的主题文章:
