Wireless sensor transmits tumor pressure

Contents under Pressure Tumors, like healthy tissues, need oxygen and nutrients to survive. In order to accommodate the demands of a growing tumor, blood vessels from surrounding tissue begin to grow into the tumor. Yet, unlike normal tissue, these newly formed blood vessels are disorganized, twisty, and leaky. It’s thought that the high pressure observed in tumors is a result of these abnormal blood vessels, which leak fluid and proteins into the area between tumor cells, known as the interstitial space…

New approach to treating human brain cancer could lead to improved outcomes

The research team, led by Robert Wechsler-Reya, Ph.D., professor in Sanford-Burnham’s NCI-Designated Cancer Center and director of the Tumor Initiation and Maintenance Program, discovered that the medulloblastoma cancer cells responsible for tumor growth and progression (called cancer stem cells or tumor-propagating cells — TPCs) divide more quickly than normal cells. Correspondingly, they have higher levels of certain enzymes that regulate the cell cycle (Aurora and Polo-like kinases). By using small-molecule inhibitors to stop the action of these enzymes, the researchers were able to block the growth of tumor cells from mice as well as humans…

Heading to the beach? New SPF regulations issued by the FDA

In the summer of 2011, Andrea Syglowski noticed a mole she’d had her entire life was starting to look different. Concerned, she booked an appointment with a dermatologist, and within a week was diagnosed with stage-0 melanoma – an early phase of the deadliest type of skin cancer. A week later, Syglowski, a Philadelphia-based actress who is in her 20s, underwent surgery to remove the mole, leaving her with a five-inch scar on her leg. Syglowski said that while she used sunscreen before her diagnosis, she now realizes she didn’t always use it correctly. “I think all I knew was that I needed to have it on,” Syglowski told FoxNews.com. Skin cancer affects millions of people like Syglowski every year, but many remain confused about the basic rules of sunscreen application. However, the Food and Drug Administration (FDA) has recently implemented new changes to sunscreen labeling, which aim to clear up some of the confusion. Here’s what to look for on sunscreen labels this summer. ‘Broad spectrum’ protection There are two types of ultraviolet light: UVA and UVB rays.  Currently, all sunscreens contain UVB protection, which shields the skin against cancer-causing sunburns. But not all sunscreens are required to have UVA protection, which protects against both skin cancer and aging. “UVB is what causes a sun burn; UVA doesn’t sunburn you. But now, we want something more. We want sunscreens to prevent cancer and wrinkles in addition to sunburn,” Dr. James Spencer, a member of the American Academy of Dermatology and a board certified dermatologist in St. Petersburg, Fla., told FoxNews.com. According to the new FDA guidelines, new sunscreen labels can only claim that they offer “broad spectrum protection” if they protect against both UVA and UVB rays. “When we say broad spectrum, we mean we're covering both UVA and UVB as wide in the spectrum as we can cover,” pharmacist Ian Ginsberg, owner of C.O. Bigelow in New York City, told FoxNews.com. Furthermore, sunscreens can now only claim to “prevent cancer” and “prevent wrinkles” if they contain both UVA and UVB protection. “It turns out that UVA contributes to cancer and wrinkles but not to burns. So now we’re asking sunscreens to help (protect us) from cancer and wrinkles too; we want that UVA added in,” Spencer said. ‘Water resistant’ not ‘waterproof’ Waterproof sunscreen may sound like a great option, but according to Spencer, “there’s no such thing as waterproof.” Sunscreen companies must now remove the word “waterproof” from their labels and replace it with the phrase “water resistant,” according to the new FDA guidelines. A “water resistant” sunscreen will be less likely to wash off in water, but doctors warn that it still needs to be reapplied. To make sure people remember to lotion up again after getting wet, the FDA now requires all sunscreens to state whether they are water resistant for “40 minutes” or “80 minutes.” “So that gives you an idea…how long you’re good for; that’s useful information,” Spencer said. And if you’ve had the same tube of sunscreen for the entire summer – you’re doing something wrong. “One tube should only last two weeks, and if you’re going to the beach, (it should last) for a week,” Dr. Hooman Khorosani, assistant professor of dermatology and chief of division of Mohs, reconstructive and cosmetic surgery at the Icahn School of Medicine at Mount Sinai in New York City, who also treated Syglowski, told FoxNews.com. Don't forget to take note of the expiration date on your tube of SPF either. Expired sunscreen could be less effective.  “Most people throw these things in their beach bag and/or let them sit in direct sunlight for hours on end so you should live by the (expiration) date,” Ginsberg said.  SPF 30, not SPF 100 Resist the urge to reach for the highest SPF on the shelf.  It likely won’t offer any more protection, according to doctors. “An SPF 30 blocks 97 percent of UBV rays - SPF 45 blocks 98 percent. Once you get to 98 percent, it’s getting a little silly. And SPF 100 is a little misleading,” Spencer said. “You can’t get more than 100 percent blocked.” Spencer said the FDA is considering prohibiting sunscreens labeled higher than SPF 50, but due to objections from sunscreen companies, the change is still being negotiated.   In the meantime, Spencer recommends looking for an SPF of at least 30 and reapplying sunscreen every few hours. Syglowski – who has now been melanoma-free for nearly two years – says she is much more vigilant about sunscreen application and schedules regular skin checks with Khorosani – something she encourages other women to do as well. As for Khorosani, he said one technique seems to be particularly effective at encouraging patients to be vigilant about sun protection. “I have a photo of a patient who sat by the window every day. The left side of her face, which was facing the window, was being hit by (wrinkle-causing) UVA rays, so it looks like she’s 50. The right side looks like she’s 35,” Khorosani said. “All I need to do is show that photo to the women who come in.”  source : http://www.foxnews.com/health/2013/05/22/heading-to-beach-new-spf-regulations-issued-by-fda/
