UCLA Study Looks at Why Heart Attacks Cause so Much More Damage in Late Pregnancy
Heart attacks during pregnancy are uncommon, but the prevalence of heart disease in pregnant mothers has increased over the past decade as more women delay pregnancy until they are older. These women, who are generally less physically active than their younger peers, tend to have higher cholesterol levels and are at greater risk of heart disease and diabetes.
While research has shown that the heart typically functions better during pregnancy due to a rise in cardiac pumping capacity to meet increased demands, a new UCLA study in rats and mice demonstrates that heart attacks occurring in the last trimester or late months of pregnancy result in worse heart function and more damaged heart tissue than heart attacks among non-pregnant females.
The research is published in the July edition of the peer-reviewed journal Basic Research in Cardiology. (more…)
Skin Patch Improves Attention Span in Stroke Patients
Researchers at the UCL Institute of Neurology have found that giving the drug rotigotine as a skin patch can improve inattention in some stroke patients.
Hemi-spatial neglect, a severe and common form of inattention that can be caused by brain damage following a stroke, is one of the most debilitating symptoms, frequently preventing patients from living independently. When the right side of the brain has suffered damage, the patient may have little awareness of their left-hand side and have poor memory of objects that they have seen, leaving them inattentive and forgetful. Currently there are few treatment options. (more…)
Mars Panorama: Next Best Thing to Being There
PASADENA, Calif. — From fresh rover tracks to an impact crater blasted billions of years ago, a newly completed view from the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity shows the ruddy terrain around the outcrop where the long-lived explorer spent its most recent Martian winter.
This scene recorded from the mast-mounted color camera includes the rover’s own solar arrays and deck in the foreground, providing a sense of sitting on top of the rover and taking in the view. Its release this week coincides with two milestones: Opportunity completing its 3,000th Martian day on July 2, and NASA continuing past 15 years of robotic presence at Mars. Mars Pathfinder landed July 4, 1997. NASA’s Mars Global Surveyor orbiter reached the planet while Pathfinder was still active, and Global Surveyor overlapped the active missions of the Mars Odyssey orbiter and Opportunity, both still in service.
