Artificial spleen to treat bloodstream infections: Sepsis therapeutic device under development Posted: 30 Mar 2013 10:05 AM PDT Scientists are developing blood-cleansing technology. The device will be used to treat bloodstream infections that are the leading cause of death in critically ill patients and soldiers injured in combat. To rapidly cleanse the blood of pathogens, the patient's blood is mixed with magnetic nanobeads coated with a genetically engineered version of a human blood 'opsonin' protein that binds to a wide variety of bacteria, fungi, viruses, parasites, and toxins.

Breaking ground in robotic cervical surgery Posted: 29 Mar 2013 09:51 AM PDT A medical researcher has used ultrasound-guided laparoscopic surgery to tighten a pregnant patient's incompetent cervix.

Monounsaturated fats reduce metabolic syndrome risk Posted: 29 Mar 2013 09:51 AM PDT Canola oil and high-oleic canola oils can lower abdominal fat when used in place of other selected oil blends, according to a new study. Researchers also found that consuming certain vegetable oils may be a simple way of reducing the risk of metabolic syndrome, which affects about one in three US adults and one in five Canadian adults.

Smoking immediately upon waking may increase risk of lung and oral cancer Posted: 29 Mar 2013 09:51 AM PDT The sooner a person smokes a cigarette upon waking in the morning, the more likely he or she is to acquire lung or oral cancer, according to researchers.

New metabolite-based diagnostic test could help detect pancreatic cancer early Posted: 29 Mar 2013 09:43 AM PDT A new diagnostic test that uses a scientific technique known as metabolomic analysis may be a safe and easy screening method that could improve the prognosis of patients with pancreatic cancer through earlier detection.

Is global warming slowing Boston Marathon winning times? Posted: 29 Mar 2013 09:43 AM PDT Researchers recently looked into whether the effects of climate change can be found in the winning times of Boston Marathon runners.

Mechanical engineering professor invents portable mobility assistant device Posted: 29 Mar 2013 09:43 AM PDT A new state-of-the-art device to assist the elderly and disabled with sitting, standing and walking.

Doctors call for training to reduce sudden cardiac arrest fatalities in schools Posted: 29 Mar 2013 06:06 AM PDT One of the leading causes of death in the United States is sudden cardiac arrest, which claims the lives of more than 325,000 people each year. Doctors found that cardiac arrests in K-12 schools are extremely rare, less than 0.2 percent, but out of 47 people who experienced cardiac arrest over a six-year period at K-12 schools, only 15 survived.

Rise in CF patient infections explained: DNA sequencing reveals evidence for Mycobacterium abscessus transmission between Cystic Fibrosis patients Posted: 29 Mar 2013 06:03 AM PDT Whole genome sequencing has explained why infection by the multidrug resistant bacteria, Mycobacterium abscessus, has been on the increase in Cystic Fibrosis patients. This study revealed that frequent transmission of the bacteria occurs between CF patients despite conventional cross-infection measures.

Innate immune system can kill HIV when a viral gene is deactivated Posted: 29 Mar 2013 05:59 AM PDT Research suggests a new target for treatment and the eventual cure of HIV/AIDS.

Eating more fiber may lower risk of first-time stroke Posted: 28 Mar 2013 01:14 PM PDT Eating more fiber may decrease your risk of first-time stroke, according to new research.

Obesity leads to decreased physical activity over time Posted: 28 Mar 2013 11:24 AM PDT Obesity leads to a decrease in physical activity over time, researchers have confirmed. The exercise science team used accelerometers to measure the actual movement and intensity of activity for 254 female participants, 124 of which were obese. Over the course of 20 months, physical activity dropped by eight percent for the group of obese individuals.
