Aspirin Ingredient Triggers Possible Cancer, Diabetes-Fighting Protein
2012-04-21 05:25:56

An international team of scientists has discovered a link between the active ingredient in aspirin and a protein which helps regulate cell growth and metabolism -- a link which could mean that the same anti-inflammatory medication and pain reliever might potentially be able to help treat cancer and prevent Type 2 Diabetes. Those researchers, who hail from at McMaster University in Canada; the University of Dundee in Scotland, and the University of Melbourne in Australia, have discovered...

Studies Indicate Fructose Not Responsible For Weight Gain
2012-02-21 09:14:33

According to a new study released this week, people who consumed a bit of extra fructose baked into breads or sprinkled into drinks did not gain additional weight compared to those who had other types of carbohydrates instead as long as they ate the same number of total calories. However, when study participants supplemented a standard diet with a dash of extra calories in the form of straight fructose, they did gain weight, reports Reuters´ Genevra Pittman. John Sievenpiper, MD,...

The Star Factory: Observing Arp 220
2012-02-20 04:07:11

The galaxy Arp 220 is home to several giant star clusters–about 10 million solar masses–that are twice as massive as any comparable star cluster in the Milky Way Galaxy. McMaster University's Christine Wilson is captivated by this turbulent galaxy that provides such a target-rich environment for watching stars form. The reason that star formation is going wild is that the galaxy is in the late stages of a merger between two larger galaxies. "This is a nearby look at a...

For decades, the blood thinner heparin has been used to prevent and treat blood clots. Could it be just as effective in treating cancer? In an editorial published today in the New England Journal of Medicine, researchers from McMaster University and the University at Buffalo suggest conclusive answers to key questions on the benefits of low molecular weight heparin (LMWH) for cancer patients remain elusive - despite promising results from large studies. Co-authors of the editorial are...

Should be considered as a control measure during pandemic outbreaks Closing elementary and secondary schools can help slow the spread of infectious disease and should be considered as a control measure during pandemic outbreaks, according to a McMaster University led study. Using high-quality data about the incidence of influenza infections in Alberta during the 2009 H1N1 flu pandemic, the researchers show that when schools closed for the summer, the transmission of infection from...

An irregular heartbeat that you don't even feel but can be picked up by a pacemaker is associated with a significantly increased risk of stroke, says a new McMaster University study. The report, published in the New England Journal of Medicine today, says that of nearly 2,600 patients without a history of atrial fibrillation but with a recently implanted pacemaker, more than one-third had episodes when the heartbeat would become rapid and irregular for more than six minutes. In 85 per...

For College Students, Regular Exercise Not A Priority
2012-01-02 11:10:14

Many things are left behind with childhood, and for college students regular exercise seems to be one of them, a new Canadian study suggests. Researchers followed 683 Canadian adolescents from 12 to 15 years old for 12 years and found a 24 percent decrease in physical activity from adolescence to early adulthood, reports Dorene Internicola for Reuters. Appearing in the American Journal of Preventive Medicine, the study showed declines were steepest among young men entering university or...

Drugs used to overcome cancer may also combat antibiotic resistance, finds a new study led by Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University. "Our study found that certain proteins, called kinases, that confer antibiotic resistance are structurally related to proteins important in cancer," says Wright about the study published in Chemistry & Biology. "The pharmaceutical sector has made a big investment in...

McMaster University researchers have found consistent evidence that use of hormone replacement therapy (HRT) is associated with breast cancer globally. This study comes at a time when more women are again asking for this medication to control hot flashes and other symptoms of menopause. The rising trend is at odds with a U.S. Women's Health Initiative (WHI) study of 2002 which found a higher incidence of breast cancer, heart attack and stroke among women using HRT. Those findings led to a...

Regular exercise has proven benefits in preventing and treating type 2 diabetes, but many patients find it tough to meet the American Diabetes Association guidelines of 150 minutes of moderate to vigorous exercise a week. A new study, conducted by researchers at McMaster University, suggests that there could be a better way. In a small proof-of-principle study in eight type 2 diabetes patients, the researchers found that exercising at a very high intensity, but for a mere 30 minutes a week...
