Physical inactivity is a known risk factor for obesity and a number of chronic diseases. Modifying the physical features of neighborhoods to provide residents with equitable and convenient access to spaces for physical activity (PA) is a promising strategy for promoting PA. Public urban recreation spaces (e.g., parks) play an important role in promoting PA and are potentially an important neighborhood element for optimizing social capital and liveability in cities. Most studies examining the effects of park availability and use on PA have focused on traditional, permanent parks...

BACKGROUND: Little attention has been paid to within-person daily associations among light physical activity (PA), moderate-to-vigorous physical activity (MVPA), and sedentary behavior (SB) with subsequent bodily pain and fatigue. Daily reports of pain and fatigue are less likely to be affected by recall bias and to conflate days of high and low pain/fatigue into one overall score. PURPOSE: The purpose of this study was to examine daily within-person associations between pain, fatigue, and physical health and ascertain whether such associations are moderated by individual differences in these variables...

Emerging evidence suggests that epigenetics regulates telomere dynamics in adults. However, the relationship between these pathways in children and youth remains unknown. Thus, we examined this association in 542 healthy adolescents aged 14 to 18 years old (44.8% African Americans; 55.2% females). Global DNA methylation level (%5-mC) was quantified using ELISA method. Leukocyte telomere length (LTL) was defined as relative telomere to single copy gene (T/S) ratio. Multiple linear regression models, adjusted for age, gender, ethnicity, Tanner stage, BMI, PA, and batch effect, revealed that %5 mC was associated with LTL (adjusted β = 0...

Mutations of solute carrier family 4 member 1 ( SLC4A1 ) gene encoding kidney anion (chloride/bicarbonate ion) exchanger 1 (kAE1) can cause genetic distal renal tubular acidosis (dRTA). Different SLC4A1 mutations give rise to mutant kAE1 proteins with distinct defects in protein trafficking. The mutant kAE1 protein may be retained in endoplasmic reticulum (ER), Golgi apparatus, or mis-targeted to the apical membrane, failing to display its function at the baso-lateral membrane. The ER-retained mutant kAE1 interacts with calnexin chaperone protein; disruption of this interaction permits the mutant kAE1 to reach the cell surface and display anion exchange activity...

Digital vascular tone and function, as measured by peripheral arterial tonometry (PAT), are associated with cardiovascular risk and events in non-Hispanic whites. There are limited data on relations between PAT and cardiovascular risk in African-Americans. PAT was performed on a subset of Jackson Heart Study participants using a fingertip tonometry device. Resting digital vascular tone was assessed as baseline pulse amplitude. Hyperemic vascular response to 5 minutes of ischemia was expressed as the PAT ratio (hyperemic/baseline amplitude ratio)...

The Autographa californica multiple nucleopolyhedrovirus (AcMNPV)-based Bac-to-Bac(®) expression system consists of a bacmid and five pFastBac™ donor transfer vectors. It has been widely used for eukaryotic gene expression in insect cells to elucidate gene function in biotechnology laboratories. The pFastBac™ vectors contain a 50bp AcMNPV polyhedrin (polh) promoter and a 127bp SV40 polyadenylation (pA) signal for cloning a gene of interest into the bacmid, resulting in unsolved lower gene expression levels than the wild type (wt) AcMNPV in insect cells...

BACKGROUND: Physical activity (PA) and its health benefits are a continuous point of discussion. Recommendations for children's daily PA vary between guidelines. To better define the amount of PA necessary to prevent overweight and obesity in children, further research is needed. The present study investigates children's compliance to physical activity guidelines (PAGs) and the association between objectively measured PA and body mass index (BMI). METHODS: Participating children were 11 years old (n = 419) and part of the European CHOP trial, which was conducted in Germany, Belgium, Poland, Spain, Italy...

Background: Malignant glioma (MG) is a devastating neuro-oncologic disease with almost invariably poor prognosis. Prognostic awareness (PA) is the awareness of incurable disease and shortened life-expectancy (LE). Accurate PA is associated with favorable psychological outcomes at the end-of-life (EOL) for patients with cancer, however little is known about PA or prognostic communication in MG. Moreover, research has yet to evaluate the impact of cognitive impairment on PA and preferred forms of communication...

Photoacoustic imaging is a promising imaging modality to visualize specific living tissues based on the light absorption coefficients without dyeing. In this study, a real-time PA imaging system with a tunable laser was newly developed with an originally designed spherically curved array transducer. Five different series of experiments were conducted to validate the PA measurement system. The peak frequency of the transducer response was 17.7 MHz, and a volume-imaging rate of 3D volume imaging was 10 - 20 volumes per second...

Dynamin-related protein 1 (Drp1) is a dynamin superfamily GTPase, which drives membrane constriction during mitochondrial division. To mediate mitochondrial division, Drp1 is recruited to the mitochondrial outer membrane and is assembled into the division machinery. We previously showed that Drp1 interacts with phosphatidic acid (PA) and saturated phospholipids in the mitochondrial membrane, and this interaction restrains Drp1 in initiating the constriction of mitochondria. Here, we show that the role of saturated acyl chains of phospholipids is independent of their contribution to the membrane curvature or lipid packing suggesting their direct interaction with Drp1...

Alfred M Sadler, Ann Davis
The history of how PAs in the United States were first granted practice authority under the medical practice acts of the various states and territories begins in the 1960s with an imaginative way to circumvent the moratorium on licensure of new healthcare occupations in place at the time, while allowing the requisite flexibility for the new profession to take hold and thrive. In the subsequent decades, separate licensure for PAs was required and adopted. Despite the enormous success of the PA profession over its first 50 years, challenges remain...

From the very beginning, popular media has played an essential role in driving public awareness and recognition of physician assistants (PAs) as major contributors to healthcare. But for PAs, popular media can be a double-edged sword. Over time, the roles of PAs have evolved from bit players to leading characters on television medical dramas. Even so, on some occasions, the roles of PAs have been marginalized and misrepresented. In the future, the PA profession will need to remain vigilant about how PAs are portrayed in the popular media and must learn how to use the full benefit of the media to promote the profession's diversity, flexibility, collegiality, and civic-mindedness...

The neurovascular coupling response has been defined for the adult brain but in the neonate non-invasive measurement of local cerebral perfusion using NIRS or BOLD fMRI have yielded variable and inconsistent results, including negative responses suggesting decreased perfusion and localised tissue tissue hypoxia. Also, the impact of permissive hypercapnia (Pa CO2  > 50 mmHg) in the management of neonates on cerebrovascular responses to somatosensory input is unknown. Using NIRS to measure changes in cerebral oxy- and deoxy-haemoglobin (ΔoxyHb, ΔdeoxyHb) in 8 anaesthetised newborn lambs, we studied the cerebral haemodynamic functional response to left median nerve stimulation using stimulus trains of 1...

The 2013 ISTH-SSC guidelines for the standardization of light transmission aggregometry (LTA) were largely based on expert consensus, as studies directly comparing LTA methodologies were lacking. We experimentally tested the cogency of ISTH-SSC recommendations pertaining to use of anticoagulant, in particular whether: (1) buffered citrate (BC) is preferable to unbuffered citrate (C); (2) the two recommended concentrations of sodium citrate (109 and 129 mM) are equivalent in terms of platelet aggregation (PA)...

Shaheen Dewji, K Lisa Reed, Mauritius Hiller
Computational phantoms with articulated arms and legs have been constructed to enable the estimation of radiation dose in different postures. Through a graphical user interface, the Phantom wIth Moving Arms and Legs (PIMAL) version 4.1.0 software can be employed to articulate the posture of a phantom and generate a corresponding input deck for the Monte Carlo N-Particle (MCNP) radiation transport code. In this work, photon fluence-to-dose coefficients were computed using PIMAL to compare organ and effective doses for a stylized phantom in the standard upright position with those for phantoms in realistic work postures...

Purpose: Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in vitro study was to measure water sorption and water solubility of two PA materials compared with PMMA, and to evaluate the major components released from the PA materials and the effect on hardness of the materials. Methods: Ten discs (40.0 mm diameter, 2.0 mm thick) of each material (PA: Valplast and Breflex; PMMA: SR Ivocap HIP) were prepared according to manufacturers' recommendations...

The ambiguous-cue task is composed of two-choice simultaneous discriminations involving three stimuli: positive (P), ambiguous (A), and negative (N). Two different trial types are presented: PA and NA. The ambiguous cue (A) served as an S- in PA trials, but as an S+ in NA trials. When using this procedure, it is typical to observe a less accurate performance in PA trials than in NA trials. This is called the ambiguous-cue effect. Recently, it was reported in starlings that the ambiguous-cue effect decreases when the stimuli are presented on an angled (120°) panel...
