Chances are, someone you know has received an ultrasound exam – to get the first glimpse of their developing baby, or maybe to determine their risk of heart attack. An ultrasound works by sending out high-frequency sound waves which reflect off body structures. A computer will then receive these reflected waves and use them to create a picture that we see on a monitor.
Whatever the use, ultrasound is one of the most utilized forms of diagnostic imaging available today after X-ray exams. But unlike an X-ray exam, an ultrasound has no ionizing radiation exposure. So what’s next for ultrasound?
Today’s modern culture provides convenience, comfort, and efficiency. In one day, an American can buy a cart of any type of groceries they desire, order an item on the Web to be delivered that afternoon, and can video chat with a friend who’s stationed in Afghanistan.
The cost of this heavy activity, according to a Stony Brook University researcher, is your health. Packing in all of these activities in a day could mean less sleep for you.
Obesity in the United States is reaching epidemic proportions and the problem is growing, especially among teens. Here’s a shocking statistic: the rate of obesity in adolescents has tripled in the past three decades.
For humans, sharks have long been the source of fascination and fear. These top predators are fast disappearing; largely due to a fishing industry that takes more than 100 million sharks out of the oceans’ depths each year.
Why should we care? Well, sharks are actually a major part of the oceans ecosystem. They help keep populations of other fish and marine animals in check by hunting sick, injured, and dying fish so that populations stay strong and healthy.
Demian Chapman, an assistant professor at Stony Brook University, studies the oceanic whitetip shark, which was once the most common shark in tropical waters and is now one of the rarest. Continue reading
One in eight women will be diagnosed with breast cancer in their lifetime. Although the survival rate is greatly improving — now over 80% (five-year) — there are a lot of improvements that may be done to help bring this to 100%. One way, according to researchers at the University at Albany, is to use a newly-developed imaging system that reduces false positives in order to provide more accurate diagnosis.
Right now mammography is the best diagnostic tool available to doctors. In most medical practices, a mammogram is used as the test to determine whether or not cancerous cells may exist in the breast tissue. And while mammography has saved countless lives, the process is not without fault. Conventional imaging techniques can sometimes miss carcinomas (the most common type of cancer cell in humans) and produce false positives.
John Leddy, director of the Concussion Management Clinic, describes the treadmill test developed by UB researchers that helps to determine whether or not concussed athletes are ready to return to play.
University at Buffalo sports medicine researchers have been awarded $100,000 from NFL Charities to develop the most objective, scientific method of determining when an athlete who has had a concussion can safely return to play.
NFL Charities, the charitable foundation of the National Football League owners, has awarded the 18-month grant to researchers at the Concussion Management Clinic in the Department of Orthopaedics, UB School of Medicine and Biomedical Sciences. The grant to UB is one of 15 totaling $1.5 million that NFL Charities is providing to researchers nationwide to support sports-related medical research on concussion/traumatic brain injury and cardiovascular medicine.
