BACKGROUND: Under particular circumstances older persons may be vulnerable to developing mild, chronic hypohydration. In young adults, hypohydration has been shown to impair muscle endurance, power and strength. Muscle performance declines with aging, a condition known as dynapenia. How hypohydration impacts muscle performance in older persons remains unclear. In this study we examined this question, believing it may identify a factor exacerbating dynapenia. METHODS: One-hour after having been passively exposed to heat where either a body mass loss of 1% was induced or euhydration maintained with fluid ingestion, eight healthy, active older men (age: 68 ± 5 yrs) completed an exercise testing session where indices of muscle strength (30-sec chair stand, grip strength, maximal isometric seated leg-press extension), endurance (seated leg-curl flexion + seated leg-press extension to exhaustion at 60% of 1-RM) and power (30-sec Wingate test) were assessed...

OBJECTIVE: To describe the publication productivity of academic urologists in the United States by gender. MATERIALS AND METHODS: Gender inequality is prevalent in most surgical subspecialties, including urology. Despite small numbers of women in academic positions, differences in scholarly impact by gender are relatively unknown. We assembled a list of 1922 academic urologists (1686 male (87.7%), 236 female (12.3%)) at 124 academic institutions throughout the United States as of February 2016...

Sedentary behavior has been linked to leading causes of morbidity and mortality, including cancer, cardiovascular disease and diabetes. Those who work in office workplaces are susceptible to higher levels of sedentary behavior during the working day. This paper introduces a novel approach to the detection of sedentary behavior through the use of a thermal sensor mounted on the ceiling above a busy workspace. This solution was found to more accurately record 7 out of 10 activity metrics in comparison to self-assessment, when compared to chair pressure sensor recordings...

This paper presents the results from actual measurements of cardiac activity acquired through the use of noninvasive sensors to detect Ballistocardiogram (BCG). The results show that it is feasible to unobtrusively monitor heart rate in non-standard settings such as waiting rooms or at school using simple chairs fitted with capacitive sensors. The selected sensors, based on electromechanical principles, are able to measure BCG from a variety of subjects. We present the results for 114 participants from homes, school and a hospital waiting room, adding up over 815 minutes of data...

Opportunistic ambient sensing involves placement of sensors appropriately so that intermittent contact can be made unobtrusively for gathering physiological signals for vital signs. In this paper, we discuss the results of our quality processing system used to extract heart rate from ballisto-cardiogram signals obtained from a micro-bending fiber optic sensor pressure mat. Visual inspection is used to label data into informative and non-informative classes based on their heart rate information. Five classifiers are employed for the classification process, i...

Individuals with post-stroke hemiparesis often have difficulty standing out of a chair. One way to potentially improve sit-to-stand is to provide knee extension assistance using a powered knee exoskeleton. An exoskeleton providing unilateral, partial assistance during sit-to-stand would need to be torque-controllable. There are no knee exoskeletons on the market suitable for conducting experiments assisting stroke patients with sit-to-stand, so to enable such experiments a research device was developed. The purpose of this report is to present the design of a novel knee exoskeleton actuator that uses a fiberglass leaf spring in series to improve torque-controllability, and present a characterization of the actuator performance...

Shoulder arthroscopy is traditionally performed with the patient in either the beach chair position or the lateral decubitus position. Each position has its advantages and disadvantages. The main topics for consideration include ease of surgery, view into the surgical field, risks to the patient, and economics of the setup. In the lateral decubitus position, it is inconvenient to work through the anterior portal and it is difficult to convert to an open procedure. In the beach chair position, it is difficult to manage the airway and cerebral oxygenation and the patient's head and the beach chair frame obstruct the insertion of a scope into the superior and posterior portals...

Photosystem II (PSII) is a huge membrane-protein complex consisting of 20 different subunits with a total molecular mass of 350 kDa for a monomer. It catalyses light-driven water oxidation at its catalytic centre, the oxygen-evolving complex (OEC). The structure of PSII has been analysed at 1.9 Å resolution by synchrotron radiation X-rays, which revealed that the OEC is a Mn4CaO5 cluster organized in an asymmetric, 'distorted-chair' form. This structure was further analysed with femtosecond X-ray free electron lasers (XFEL), providing the 'radiation damage-free' structure...
