Older adult participants’ respiration, pulse, and restlessness are monitored as they sleep. Gait speed, stride length, Dinaciclib and stride time are calculated daily, and automatically assess for increasing fall risk. Activity levels are summarized and graphically displayed for easy interpretation. Falls are detected when they occur and alerts are sent immediately to healthcare providers, so time to rescue may be

reduced. Automated health alerts are sent to healthcare staff, based on continuously running algorithms applied to the sensor data, days and weeks before typical signs or symptoms are detected by the person, family members, or healthcare providers. Discovering these new functional status ‘vital signs’, developing automated methods for interpreting them, and alerting others when changes occur have the potential to transform chronic illness management and facilitate aging in place through the end of life. Key findings of research in progress at the University

of Missouri are discussed in this viewpoint article, as well as obstacles to widespread Selleckchem Anlotinib adoption. (C) 2014 S. Karger AG, Basel”
“Background-Cardiovascular disease is the leading cause of death for both men and women in the United States and the world. A profound pattern exists in the time of day at which the death occurs; it is in the morning, when the endothelium is most vulnerable and blood pressure surges, that stroke and heart attack most frequently happen. Although the molecular components of circadian rhythms rhythmically oscillate in blood vessels, evidence of a direct function for the “circadian clock” in the progression to vascular disease is lacking.\n\nMethods and Results-In the present study, we found increased pathological remodeling and vascular injury in mice with aberrant circadian rhythms, Bmal1-knockout and Clock mutant.

In addition, naive aortas from Bmal1-knockout AZD1480 concentration and Clock mutant mice exhibit endothelial dysfunction. Akt and subsequent nitric oxide signaling, a pathway critical to vascular function, was significantly attenuated in arteries from Bmal1-knockout mice.\n\nConclusions-Our data reveal a new role for the circadian clock during chronic vascular responses that may be of significance in the progression of vascular disease.

“PURPOSE. To elucidate the influences of light exposure on the retinal pigment epithelium (RPE) in vivo that may be involved in the pathogenesis of AMD.\n\nMETHODS. Six-to 7-week-old BALB/c mice were exposed to light at 2000 lux for 3 hours.
