MRI Contrast Agents Accumulate in the Brain

The International Society for Magnetic Resonance in Medicine (ISMRM) has provided new guidance in the use of contrast agents during MRI scans. Emerging research suggests gadolinium-based contrast agents, injected in a patient’s veins to brighten tissues in MRI images, accumulate in the brain. More than 300 million doses of such drugs have been administered since [...]

Adolescent depression increases risk for violence

Adolescent depression increases the risk of violence, suggests a study published in the August 2017 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP). The study examined the longitudinal association between depression and subsequent violence from three representative samples in the Netherlands, United Kingdom and Finland. This research is important [...]

Global Warming May Cause Spike in Asthma, Allergy Symptoms

A new study finds that exposure to a widespread outdoor fungus can increase cell damage (oxidative stress) in the airways. This spike weakens the airways’ barrier defense system that, when functioning normally, removes infection- and allergy-causing organisms (mucociliary clearance). The study, published ahead of print in the American Journal of Physiology—Cell Physiology, was chosen as [...]

Cancer deaths and cases attributable to lifestyle factors and infections in China

The burden of cancer in China is high, and it is expected to further increase. Information on cancers attributable to potentially modifiable risk factors is essential in planning preventive measures against cancer. We estimated the number and proportion of cancer deaths and cases attributable to ever-smoking, second-hand smoking, alcohol drinking, low fruit/vegetable intake, excess body [...]

Cigarette damage to unborn children revealed

Scientists say the potent cocktail of chemicals in cigarettes is particularly harmful to developing liver cells and affects male and female fetuses differently. The stem cell technique will provide important information about the long-term effects of maternal cigarette smoking. The liver is vital in clearing toxic substances and plays a major role in regulating metabolism. [...]
