Intestinal Cells Surprisingly Active In Pursuit Of Nutrition And Defense
Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria. In the June 29, 2009 issue of the Journal of Cell Biology, Matthew McConnell, Matthew Tyska, and colleagues now find that microvilli extend their functional reach even further using a molecular motor to send vesicles packed with gut enzymes out into the lumen to get a head start on breaking down their substrates.

Studies Highlight A Revolutionary New Method Of Treating Post-Operative Bruising

Candela Corporation (NASDAQ: CLZR) announced that two studies have reported superior results on patients who benefited from the Candela Vbeam® laser treatments for bruising resulting from cosmetic procedures. The studies concluded that the Vbeam pulsed-dye laser significantly expedited the healing process, improved outcomes, and provided greater overall patient satisfaction. A study published in the March/April 2009 edition of the Archives of Facial Plastic Surgery, entitled: "Pulsed-Dye Laser for Treating Ecchymoses After Facial Cosmetic Procedures" by DeFatta, R. J., Krishna, S., and Williams, E. F., III concluded that "the Vbeam laser treatment resulted in a 63% mean improvement in ecchymoses scores within forty-eight (48) to seventy-two (72) hours." The second study, a 2009 ASLMS abstract, entitled: "A Simple Solution to a Common Problem" evaluated the effectiveness and safety of the long-pulse PDL (the Vbeam) for the treatment of ecchymoses. In this study by Elizabeth Hale, M.D., Julie Karen, M.D., Chris Hunzeker, M.D., Elliot Weiss, M.D., Leonard Bernstein, M.D., Lori Brightman, M.D., Anne Chapas, M.D., and Roy Geronemus, M.D. results showed that twenty-four hours post-treatment with the Vbeam laser, the average improvement was 62% and 13% for treated and untreated bruises, respectively. Edwin F. Williams, M.D., Director, The Williams Center Plastic Surgery Specialists, and nationally recognized plastic surgeon pioneered this breakthrough Vbeam treatment. "Anytime you penetrate the skin there is a potential for bruising and we find that it is the bruising which occurs after many of these procedures that prevents patients from getting out into the public. It is extremely difficult to cover these unsightly marks with make-up and bruising can last for a number of weeks," said Dr. Williams. Dr. Williams continued, "After just one treatment with the Vbeam, our patients experience dramatic clearance of the injured blood vessels. This treatment is a significant differentiator to our practice and we are excited to finally be able to offer our patients a safe and easy treatment of bruising that works!" Roy G. Geronemus, M.D., Director, Laser & Skin Surgery Center of New York, commented, "There are millions of surgical and injectable procedures performed every year which often have bruising as a side effect that can last up to two weeks." Dr. Geronemus continued, "This is a significant new use for the Vbeam which was already our "workhorse" laser because of its efficacy and safety profile for a wide variety of applications including skin rejuvenation, the treatment of rosacea, acne, diffuse redness, scars and more."
