چکیده
Frequent blood pressure monitoring is the key to diagnosis and treatments of many severe diseases. However, conventional ambulatory methods require patients carry a (BP) device for 24 h conduct measurement every 10--15 min. Despite their extensive usage, wearing wrist/arm-based BP long time has significant impact on users' daily activities. To address problem, we developed eBP measure from inside user's ear aiming minimize measurement's normal activities although maximizing its comfort level. The novelty includes (1) light-based inflatable pulse sensor which goes ear, (2) digital air pump with fine controller, (3) estimation algorithms that eliminate need blocking flow ear. Through comparative study 35 subjects, can achieve average error 1.8 mmHg systolic (high-pressure value) -3.1 diastolic (low-pressure standard deviation 7.2 7.9 mmHg, respectively. These results satisfy FDA's AAMI standard, requires mean less than 5 8 mmHg.

This article comes out of many discussions I have had lately with Kansans as well as other colleagues around the country about the applicability of implementing the evidence-based practice of supported employment in rural and frontier areas. There are special challenges in rural areas, but so are there special challenges in urban areas. However, there appears to be some misconceptions regarding...

The problem was first recognized (in the late 1980’s) in conjunction with an increase in the number of inpatient psychiatric hospitalizations. Senior management at the agency began researching and evaluating program data to determine the cause of the increase. The active use of substances was found to be a contributor. This process of problem recognition at Thresholds contains key components fo...
متن کاملDefective adipocyte differentiation in mice lacking the C/EBP and/or C/EBP gene
To investigate the role of C/EBP family members during adipocyte differentiation in vivo, we have generated mice lacking the C/EBPβ and/or C/EBPδ by gene targeting. Approximately 85% of C/EBPβ(–/–)·δ(–/–) mice died at the early neonatal stage. By 20 h after birth, brown adipose tissue of the interscapular region in wild-type mice contained many lipid droplets, whereas C/EBPβ(–/–)·δ(–/–) mice di...
