Canada needs minimum training standards for laser hair removal operators, as currently anyone, trained or not, can legally operate a laser machine for hair removal in Canada, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100475.pdf.
In Canada, no license is required to operate a laser hair removal machine and training is usually provided by the manufacturer. Only the machine itself is licensed by Health Canada.
St. Louis, MO, April 12, 2010 – More than one third of Americans are considered obese and approximately 15 million (5%) Americans now have a body mass index (BMI) greater than 40. The April issue of the Journal of the American Dietetic Association focuses on the ever-increasing use of bariatric surgery to control the excess morbidity and mortality associated with extreme obesity and the important role that registered dietitians play in the management of patients who have undergone the procedure.
Pathogens can now be easily tracked in time and space as they evolve, an advance that could revolutionize both public health and inform national security in the fight against infectious diseases. Developed by researchers that include scientists at the American Museum of Natural History, Supramap (supramap.osu.edu) is a new, powerful, web-based application that maps genetic mutations like those among the different strains of avian influenza onto the globe.
A new study from North Carolina State University shows that size plays a key role in determining the structure of certain hollow nanoparticles. The researchers focused on nickel nanoparticles, which have interesting magnetic and catalytic properties that may have applications in fields as diverse as energy production and nanoelectronics.
TORONTO, Ont., April 12, 2010— It's well known that many women remain in abusive relationships with their male partners. A new study by researchers in Toronto and New York suggests that many who live with chronic psychological abuse still see certain positive traits in their abusers—such as dependability and being affectionate—which may partly explain why they stay.
COLUMBUS, Ohio – Researchers here are hopeful that the new core they drilled through an ice field on the Antarctic Peninsula will contain ice dating back into the last ice age. If so, that record should give new insight into past global climate changes.
The expedition in early winter to the Bruce Plateau, an ice field straddling a narrow ridge on the northernmost tongue of the southernmost continent, yielded a core that was 445.6 meters (1,462 feet) long, the longest yet recovered from that region of Antarctica.
Exposure to an increased level of air pollutants, especially nitrogen dioxide, has been associated with lower likelihoods of successful pregnancy among women undergoing in vitro fertilization, according to a team of fertility researchers.
The team examined the outcomes of the first pregnancy attempt of 7,403 women undergoing IVF at Penn State Milton S. Hershey Medical Center, Hershey, Pa.; Shady Grove Fertility, Rockville, Md.; and Columbia University College of Physicians and Surgeons, New York, N.Y. They conducted their observations over a seven-year period from 2000 to 2007.
URBANA - The 1996 U.S. Farm Bill eliminated many acreage restrictions, thereby allowing farmers to plant what they believe to be their most competitive crops. A study conducted by University of Illinois agricultural economists evaluated subsequent acreage changes across crops to better understand which crops have been most profitable during a period when farm legislation contains few acreage constraints.
Do you carry a cell phone? Today, chances are it's called a "smartphone" and it came with a three-to-five megapixel lens built-in—not to mention an MP3 player, GPS or even a bar code scanner. This 'Swiss-Army-knife' trend represents the natural progression of technology—as chips become smaller/more advanced, cell phones absorb new functions.
What if, in the future, new functions on our cell phones could also protect us from toxic chemicals?
Nearly one in ten primary care physicians in the United States has experienced a conflict with a religiously-affiliated hospital or practice over religious policies for patient care, researchers from the University of Chicago report in a paper published early online in the Journal of General Internal Medicine.
Imagine a car dealership where telling a salesperson "I'm just looking" would allow you to do just that. Or an online retailer offering you price cuts or free shipping to improve its relationship with you.
That's what shopping experiences might be like if more retailers paid attention to the findings of a Kansas State University marketing professor and his research collaborators.
BLOOMINGTON, Ind. -- To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have devised an unusual solution -- attach what amounts to a 3-D bramble patch to each side of the carbon sheet. Using that method, the scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, a first.
The scientists' report, online today (April 9), will appear in a future issue of Nano Letters, an American Chemical Society journal.
Could inexpensive wireless sensors based on nanotechnology be used to alert engineers to problematic cracks and damage to buildings, bridges, and other structures before they become critical? A feasibility study published in the International Journal of Materials and Structural Integrity would suggest so.
Esophagectomy is a standard treatment for resectable esophageal carcinoma but relatively few patients are cured. Combined neoadjuvant chemoradiotherapy (CRT) or adjuvant CRT with surgery may improve survival but there is concern about treatment morbidity and the best sequencing of CRT and surgery.
For anyone who has spent a significant amount of time in an urban setting, the scene of a bomb squad responding to a report of a suspicious package might be all too familiar. But just how is it determined that the lunchbox left under the park bench is just leftovers – or a lethal weapon? The most common way is spectroscopy.
