Researchers now have the physical evidence to show why it’s important for older people to exercise. And it comes with the discovery that, in aging racehorses, regular aerobic workouts decreased the prevalence of muscle damage that can be caused by exertion.
Mammalian skeletal muscle tissue is the same regardless of which species of mammal it is in, said Steven Devor, the study’s lead author and an assistant professor of exercise science education at Ohio State University.
Revolutionary advancements in the treatment options for diseases associated with human papillomavirus (HPV) now include nonsurgical options such as chemoprevention and vaccines. A review of these methods is published in the latest issue of the International Journal of Gynecological Cancer.
The standard treatment to date has been to surgically remove the infected tissue, which puts patients at risk for reproductive consequences and does not ensure that all infected tissue has been
Researcher at Rice University’s Baker Institute recommends good public policy
Many opponents of needle-exchange programs argue that supplying drug users with clean needles sends the wrong message. But a researcher at Rice University’s Baker Institute for Public Policy advises that they should be concerned about the message they’re actually sending. Despite the overwhelming evidence that needle-exchange programs (NEPs) can help reduce the spread of HIV/AIDS and hepatitis, many legisl
For several years, crippling leg pain has prevented Joan Erickson from walking more than a block. If she paused to rest, she could walk a little more, but not enough to continue playing golf, her favorite pastime.
An ultrasound and CT scan early this year showed that an artery in Erickson’s thigh was almost completely blocked, confirming that her troubles were caused by peripheral arterial disease, or PAD – a condition in which arteries to the arms, legs or internal organs are har
Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.
“What we’re finding with CT screening are more early-stage cancers. That could be good news–finding cancers that we’d otherwise find at a late stage,” said the study’s lead author, Stephen J. Swens
The health of the public is being put at risk by recommendations to cover up and stay out of the sun in the UK. These recommendations, which are part of Cancer Research UK’s SunSmart programme, increase the risk of several types of cancer, and may also increase deaths from melanoma, the most serious form of skin cancer.
Increased exposure to sunlight or greater intake of vitamin D has been found to reduce the risk of five common cancers in case/control studies. These are cancer
Acupuncture, in combination with exercise in the home, is clearly the best way to alleviate pain in pregnant women in connection with symphysiolysis, or slippage in the cartilage holding together bones. This is shown in research from the Sahlgrenska Academy at Göteborg University in Sweden, that is being published in the British Medical Journal BMJ.
Pelvic pain, so-called symphysiolysis, is a common disorder among pregnant women throughout the world. One third of those affect
A study by researchers into the diagnosis of patients with lung cancer suggests that avoidable patient delays in reporting symptoms of the disease is an important factor in its treatment.
The research carried out by the University of Southampton indicates that the widely held view that lung cancer is silent until far advanced may be inaccurate.
Lung cancer remains the most common cause of death from cancer in the UK with over 33,000 deaths a year. Delay in the diagnosis of
Retinitis pigmentosa (RP) is an inherited eye disease that causes visual disability leading to blindness. Over the last 15 years, researchers have pinpointed defects in dozens of genes causing different forms of RP. Surprisingly, patients with the same genetic defect can show different severities of vision loss and rates of disease progression. This effect is most dramatic across the retina of some individuals where regions with normal vision can abut regions of no vision. Environmental factors ha
Study suggests combination therapy could stop spread, halt growth of melanomas
PA- Researchers at Penn State College of Medicine have identified the mechanism by which the most mutated gene in melanoma, called v599EB-Raf, aids melanoma tumor development demonstrating its importance as a therapeutic target.
“Our studies suggest that using therapies to target and inhibit the function of mutant v599EB-Raf protein could prevent the spread of melanoma and halt tumor growth for t
Navarre University Hospital has introduced a novel technique for the treatment of congenital heart defects and involving the percutaneous closure of the patent foramen ovale (PFO) with monitoring through intracavernous ecography.
PFO is a defect of the interauricular septum (partition or wall separating the two (auricles) and that allows blood clots or thrombi to pass from the right auricle to the left. In most cases this opening closes after the baby is born but, on occasions, it s
Only one of five cancer survivors surveyed in a Penn State study were disabled or out of work four years after treatment, but a minority suffered lasting effects that prevented them from working.
Dr. Pamela Farley Short, professor of health policy and administration and demography who led the study, says, “One of the reassuring findings from this study is that encouraging people to get mammograms to detect breast cancer and PSA tests to check for prostate cancer has clearly ha
New generation lenses help protect against infection
Sleeping in contact lenses can lead to an increased risk of severe eye infection, new research suggests. But new generation contact lenses, the investigation reveals, perform better in this regard than their predecessors.
The University of Manchester study found that wearers who failed to remove their lenses before bedtime had an increased risk of developing keratitis than those who routinely took out their lenses b
New reports prove that the aloe vera plant, which has been used to heal skin for more than 2,000 years, can also treat many oral health problems including canker sores, cold sores, herpes simplex viruses, lichen planus and gingivitis according to the January/February issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical, peer-reviewed journal.
“There is good evidence to support using aloe vera for oral health problems,” says AGD spokesperson Kenton A.
Parents know all too well the pain experienced by their children – and themselves – when the time comes for immunizations at the doctor’s office.
But a new MicroJet injector being developed by bioengineering students at the University of California, Berkeley, may help ease some of that dread by taking the needle – and the pain – out of the equation. The MicroJet uses an electronic actuator that could one day propel vaccinations, insulin or other drugs through the skin of
That seven-day-old bag of spinach in your refrigerator may not make you as strong as your grandma told you, because, according to Penn State food scientists, spinach stored for a long time loses much of its nutrient content.
Luke LaBorde, associate professor of food science, and Srilatha Pandrangi, graduate student, both at Penn State, found that spinach stored at 39 degrees Fahrenheit loses its folate and carotenoid content at a slower rate than spinach stored at 50 and 68 degree
