Here is what real commitment to your marriage means Posted: 01 Feb 2012 03:14 PM PST What does being committed to your marriage really mean? A psychology professors answer this question in a new study based on their analysis of 172 married couples over the first 11 years of marriage.

Powering pacemakers with heartbeat vibrations Posted: 01 Feb 2012 03:14 PM PST Aerospace engineers have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats.

Need an excuse to book a massage? Massage reduces inflammation and promotes growth of new mitochondria following strenuous exercise Posted: 01 Feb 2012 11:17 AM PST About 18 million individuals undergo massage therapy annually in the U.S. Despite several reports that long-term massage therapy reduces chronic pain and improves range of motion in clinical trials, the biological effects of massage on skeletal tissue have remained unclear - until now.

'Life and activity monitor' provides portable, constant recording of vital signs Posted: 01 Feb 2012 11:00 AM PST Researchers have developed a type of wearable, non-invasive electronic device that can monitor vital signs such as heart rate and respiration at the same time it records a person's activity level, opening new opportunities for biomedical research, diagnostics and patient care.

New technology shows molecules and cells in action Posted: 01 Feb 2012 10:53 AM PST A new affinity capture device provides a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments.

Sleep deprivation tied to increased nighttime urination in preadolescence Posted: 01 Feb 2012 10:53 AM PST A new study sheds light on why some children may need to urinate more often during the rest cycle. Researchers found sleep deprivation caused healthy children, ages 8-12, to urinate significantly more frequently, excrete more sodium in urine, have altered regulation of the hormones important for excretion.

Societal control of sugar essential to ease public health burden, experts urge Posted: 01 Feb 2012 10:53 AM PST Sugar should be controlled like alcohol and tobacco to protect public health, according to a team of researchers, who maintain in a new report that sugar is fueling a global obesity pandemic, contributing to 35 million deaths annually worldwide from non-communicable diseases like diabetes, heart disease and cancer.

Chaos in the cell's command center Posted: 01 Feb 2012 10:53 AM PST Researchers have determined the critical role one enzyme, lysine-specific demethylase 1 (LSD1), plays as mouse embryonic stem cells (ESCs) differentiate. This research may provide targets for developing drugs to push cells with dysfunctional gene expression programs back to a more normal, healthier state.

Why the brain is more reluctant to function as we age Posted: 01 Feb 2012 07:51 AM PST New findings reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.

Encouraging results with stem cell transplant for brain injury Posted: 01 Feb 2012 07:45 AM PST Experiments in brain-injured rats show that stem cells injected via the carotid artery travel directly to the brain, where they greatly enhance functional recovery.

Sleep apnea linked to silent strokes, small lesions in brain Posted: 01 Feb 2012 06:43 AM PST People with severe sleep apnea may have an increased risk of silent strokes and small lesions in the brain, according to a small study.

Clot-busting drugs appear safe for treating 'wake-up' stroke patients Posted: 01 Feb 2012 06:43 AM PST Clot-busting drugs may be safe for patients who wake up experiencing stroke symptoms, according to preliminary research.

Experimental drug reduces 'second stroke' after aneurysm rupture Posted: 01 Feb 2012 06:43 AM PST An experimental drug, clazosentan, reduced the risk of blood vessel spasm in patients with a brain aneurysm, according to new research.

Infections in childhood linked to high risk of ischemic stroke Posted: 01 Feb 2012 06:43 AM PST Common infections in children pose a high risk of ischemic stroke, according to new research. In a review of 2.5 million children, the researchers identified 126 childhood ischemic stroke cases and then randomly selected 378 age-matched controls from the remaining children without stroke. They discovered that 29 percent of those who suffered a stroke had a medical encounter for infection in the two days preceding the stroke versus one percent of controls during the same dates.

Severe, rapid memory loss linked to future, fatal strokes Posted: 01 Feb 2012 06:43 AM PST Severe, rapid memory loss may be linked to -- and could predict -- a future deadly stroke, according to new research.

Re-blockage rates low in both stented and surgically-opened arteries, study finds Posted: 01 Feb 2012 06:43 AM PST In a large, head-to-head comparison of two procedures that clear blocked neck arteries, outcomes were similar. The study found that 94 percent of the arteries remained open two years after using surgery or a metal stent.

Type of anesthesia may affect recurrence risk after liver cancer procedure Posted: 31 Jan 2012 09:12 AM PST For patients undergoing a minimally invasive treatment for liver cancer, the risk of recurrent cancer appears lower with general anesthesia compared to regional (epidural) anesthesia, according to a new study.

Local anesthetic stops pain at the source after hip replacement surgery Posted: 31 Jan 2012 09:12 AM PST In patients undergoing hip replacement surgery, using a special wound catheter to infuse local anesthetic directly into the hip joint provides significant and lasting improvements in postoperative pain control, according to a new study.
