KINGSTON, R.I. – November 28, 2012 – A team of archaeologists from the University of Rhode Island, the Israel Antiquities Authority, and the University of Louisville have discovered the remains of a fleet of early-19th century ships and ancient harbor structures from the Hellenistic period (third to first century B.C.) at the city of Akko, one of the major ancient ports of the eastern Mediterranean. The findings shed light on a period of history that is little known and point to how and where additional remains may be found.

LOS ANGELES (Nov. 28, 2012) – Cedars-Sinai Heart Institute researchers have found in an initial clinical trial that a drug typically prescribed for erectile dysfunction or pulmonary hypertension restores blood flow to oxygen-starved muscles in patients with a type of muscular dystrophy that affects males, typically starting in childhood or adolescence.
(SACRAMENTO, Calif.) — Amid increasing fear of overexposure to radiation from CT scans, a panel of experts has recommended more research on the health effects of medical imaging and ways to reduce unnecessary CT tests, as well as industry standardization of CT machines.
A youth offending facility in the East Midlands has been criticised in a new report for taking criminals from rival gangs in Leicester and Nottingham.
The research, led by an academic at Nottingham University Business School, said that the policy by Glen Parva Young Offenders Institution to take criminals from both cities was a recipe for trouble and has led to an increase in violence and gang warfare.
PROVIDENCE, R.I. – It probably won't come as a surprise to hear that most adult entertainment club workers – exotic dancers and other female club employees such as bartenders, waitresses and hostesses – don't have great medical benefits. The nature of their work makes them easy prey for repeated unwanted sexual advances and behavior. Add in the prevalence of risky sexual behavior and substance abuse and you've got a perfect storm for unchecked health risks.
Amsterdam, the Netherlands: The latest Access to Medicine Index, which ranks the top 20 pharmaceutical companies on their efforts to improve access to medicine in developing countries, finds that the industry is doing more than it was two years ago, with GlaxoSmithKline still outperforming its peers, but an expanding group of leaders closing the gap.
CHICAGO – The role of radiologists in healthcare has long been poorly understood among the general public, but new research presented today at the annual meeting of the Radiological Society of North America (RSNA) shows that even patients who've had imaging exams in the past know little about the profession.
Researchers said the study findings highlight an opportunity for radiologists to educate the public about their role in healthcare.
CHICAGO – Visceral, or deep belly, obesity is a risk factor for bone loss and decreased bone strength in men, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"It is important for men to be aware that excess belly fat is not only a risk factor for heart disease and diabetes, it is also a risk factor for bone loss," said Miriam Bredella, M.D., radiologist at Massachusetts General Hospital and associate professor of radiology at Harvard Medical School in Boston.
CHICAGO – While obesity is considered a cardiovascular risk factor, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) showed that African-American patients with coronary artery disease (CAD) have much less fat around their hearts compared to Caucasian patients.
Digoxin, a drug that has been used worldwide for centuries to treat heart disease, is associated with a significant increase in deaths in patients with atrial fibrillation (AF), according to results from a study published online today (Wednesday) in the European Heart Journal [1].
People with an overactive thyroid gland (hyperthyroidism) carry a greater risk of developing irregular heart rhythm (known as atrial fibrillation) than those with normal thyroid function, finds a study published on bmj.com today.
As such, the researchers suggest there should be an increased focus on atrial fibrillation in patients with raised thyroid function.
Toronto, ON (27 November, 2012) -- A new method of growing cardiac tissue is teaching old stem cells new tricks. The discovery, which transforms aged stem cells into cells that function like much younger ones, may one day enable scientists to grow cardiac patches for damaged or diseased hearts from a patient's own stem cells—no matter what age the patient—while avoiding the threat of rejection.
CHICAGO – An analysis of two heart failure therapies finds differing outcomes regarding improvement in survival, according to two studies appearing in the November 28 issue of JAMA.
In one study, Adrian F. Hernandez, M.D., M.H.S., of the Duke Clinical Research Institute, Durham, N.C., and colleagues examined the clinical effectiveness of aldosterone antagonist therapy and associations with long-term outcomes of older patients discharged from a hospitalization for heart failure.
DURHAM, N.C. – A large study addressing the effectiveness and safety of aldosterone antagonist therapy for older heart failure patients has found notable differences between the drug's results in clinical trial vs. what occurs in actual practice, according to researchers at Duke Medicine.
Those differences have been noted anecdotally by doctors, and likely contributed to the slow adoption of aldosterone antagonists in clinical practice, but they had not been confirmed in a large study examining the drugs in real-world situations.
A novel study from Karolinska Institutet in Sweden suggests that commonly used drugs to treat heart failure and high blood pressure may have a wider range of application than earlier known, and also can be used against so called HFPEF -- a type of heart failure that until now has been impossible to treat. The study, which is published in the scientific journal JAMA, shows that the mortality rate in a group of HFPEF patients who used these medications decreased.
