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...

Researchers at McMaster University have found that brief high intensity workouts, as little as six sessions over two weeks, rapidly lower blood sugar levels in type 2 diabetics, offering a potential fix for patients who struggle to meet exercise guidelines. The small proof-of-principle study, conducted on eight diabetics, appears in the latest edition of the Journal of Applied Physiology. It found that a total of 30 minutes of high-intensity intermittent exercise per week, involving a...

Salt Consumption Debate: Too Much Or Too Little?
2011-11-23 12:56:56

Doctors and health experts have warned us for years that too much salt intake is bad for our health, but a new study from researchers at McMaster University in Hamilton, Ontario, Canada suggests that too little salt intake may be just as bad for our heart health as higher doses. The new study suggests that in people with heart disease, eating too little salt is linked to a higher risk of heart-related hospitalizations and deaths nearly as much as too much salt intake. It also suggests that...

In the fight for survival, plants are capable of complex social behaviours and may exhibit altruism towards family members, but aggressively compete with strangers. A growing body of work suggests plants recognize and respond to the presence and identity of their neighbours. But can plants cooperate with their relatives? While some studies have shown that siblings perform best -- suggesting altruism towards relatives -- other studies have shown that when less related plants grow together...

Diet Rich In Veggies And Fruit Reduces Heart Disease Risk
2011-10-12 12:26:57

Researchers found a genetic risk for cardiovascular disease that may be modifiable through a change in diet. The team wrote in the journal PLoS Medicine that the risk of the disease was decreased in individuals who ate a diet rich in raw fruits and vegetables. "Despite having a high genetic risk for heart disease, a healthy lifestyle can actually turn off the gene," Dr. Sonia Anand, Professor of Medicine and Epidemiology at the Michael G. DeGroote School of Medicine at McMaster...

A long-held mantra suggests that you can't change your family, the genes they pass on, or the effect of these genes. Now, an international team of scientists, led by researchers at McMaster and McGill universities, is attacking that belief. The researchers discovered the gene that is the strongest marker for heart disease can actually be modified by generous amounts of fruit and raw vegetables. The results of their study are published in the current issue of the journal PLoS Medicine....
