An international study led by The Australian National University (ANU) has found evidence that marine life can easily invade Antarctic waters from the north, and could be poised to colonise the rapidly-warming Antarctic marine ecosystems.
The Antarctic Polar Front, a strong ocean front formed where cold Antarctic water meets warmer waters to the north, has historically been seen as a barrier preventing movement of marine life.
San Diego, CA (May 24, 2016) -- People with obesity who are struggling to control their weight might soon have a new treatment option -- swallowing gas-filled balloons that help them eat less, according to research presented at Digestive Disease Week® (DDW) 2016, the largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery.
San Diego, CA (May 22, 2016) -- A new study shows the rate of colorectal cancer (CRC) continues to increase in individuals under 50 years old, despite the fact that the overall rate of the disease has been declining in recent years. Following examination of more than 1 million CRC patient records over 10 years, researchers suggested that health-care providers should be more vigilant about detecting symptoms in younger patients.
TORONTO, May 24, 2016 -- Obesity rates in Southern Ontario cities have remained stable for more than a decade in highly walkable neighborhoods but continued to rise in less walkable ones, a new study has found. Neighbourhoods that were designed to be more walking-friendly also experienced a fall in the rate of new cases of diabetes.
The study, led by Dr. Gillian Booth, an endocrinologist and researcher at St. Michael's Hospital and an adjunct scientist at the Institute for Clinical Evaluative Sciences, was published today in the journal JAMA.
WASHINGTON, DC - May 24, 2016 - The bacterium Burkholderia multivorans evolves and adapts in bursts to survive in the lungs of cystic fibrosis patients, according to a study published this week in mSystems, an open access journal from the American Society for Microbiology. The work, believed to be the first retrospective look at the evolution of this microorganism, indicates that B. multivorans directly or indirectly targets adherence, metabolism and changes to the cell 'envelope' to stick around and evade antibiotics.
Washington, DC -- Obese teenagers already show signs of hormonal differences from normal-weight peers that may make them prone to weight gain, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The study found obese teenagers have lower levels of a hormone potentially tied to weight management than normal-weight teens. Studies of adults have found that the hormone, called spexin, is likely involved in regulating the body's fat mass and energy balance.
Washington, DC -- Exposure to air pollution can worsen blood sugar levels, cholesterol and other risk factors for heart disease, particularly in people with diabetes, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
In a study appearing in the May 24/31 issue of JAMA, Jenna Wong, M.Sc., of McGill University, Montreal, Canada, and colleagues analyzed treatment indications for antidepressants and assessed trends in antidepressant prescribing for depression.
Urban neighborhoods in Ontario, Canada, that were characterized by more walkable design were associated with decreased prevalence of overweight and obesity and decreased incidence of diabetes between 2001 and 2012, according to a study appearing in the May 24/31 issue of JAMA.
The discovery of early changes in the cells of the Fallopian tubes of women carrying the BRCA genetic mutation could open the way for new preventative strategies for ovarian cancer, reducing the need for invasive surgery, according to research published today in science journal Nature Communications.
The highly anticipated document gives the latest advice on prevention of cardiovascular disease (CVD) in individuals and populations. It is published in European Heart Journal,1 the European Journal of Preventive Cardiology and other specialty journals, and presented in a dedicated session at Heart Failure 2016 and the 3rd World Congress on Acute Heart Failure in Florence, Italy.2
WASHINGTON, D.C., May 24, 2016 -- Look out over the ocean and you might get the impression that it's a mass of water acting as a single entity. However, the world's oceans are made up of layers of different densities, called stratifications, with complex fluid dynamics. Often bulges, called mode-2 internal waves, form in the thickness of these layers, trapping materials inside that then move along with the wave. For the first time, two mathematicians at Canada's University of Waterloo have created a 3-D simulation of the mass transport capabilities of mode-2 waves.
Coral reefs - stunning, critical habitats for an enormous array of prized fish and other species - have survived five major extinction events over the last 250 million years.
Although Cercopithecus monkeys, a widely distributed genus in Africa, usually have a discerning palate for fruits and leaves, they are opportunistic omnivores that sometimes consume lizards, snakes, birds and mice. These forest-dwelling primates share habitat and food resources with bats, which are known reservoirs for zoonotic diseases such as Ebola, Marburg and Henipa viruses as well as bacteria and parasites that can be spread between animals and humans.
Researchers at the University of Eastern Finland and Eberhard Karls Universität Tübingen have discovered a new molecular mechanism that can be used to inhibit the growth of hepatocellular carcinoma, which is the most common liver cancer. The findings were published in Nature Medicine.
