STUDY DESIGN: Cadaveric radiostereometric analysis study. OBJECTIVE: To quantify the ability of 5 commonly used immobilizers to restrict cervical spine movement, including intervertebral movement, in three directions. SUMMARY OF BACKGROUND DATA: Evidence about the ability of many clinically used cervical immobilizers to restrict cervical movement is limited. Furthermore, their effect on intervertebral movement is unknown. METHODS: Radiographic inert beads were implanted in the cervical vertebral bodies of five fresh-frozen human cadavers...

Chemically synthesized crosslinkers play decisive roles in variable cargos attached to nanoparticles (NPs). Previous studies reported that surface properties, such as the size, charge, and surface chemistry, are particularly important determinants influencing the biological fate and actions of NPs and cells. Recent studies also focused on the relationship of serum proteins with the surface properties of NPs (also called the protein corona), which is recognized as a key factor in determining the cytotoxicity and biodistribution...

Diastolic dysfunction contributes to the development and progression of heart failure. Conventional echocardiography and tissue Doppler imaging are widely utilised in clinical research providing a number of indices of diastolic function valuable in the diagnosis and prognosis of heart failure patients. The aim of this meta-analysis was to quantify the effect of exercise training on diastolic function in patients with heart failure. Exercise training studies that investigate different indices of diastolic function in patients with heart failure have reported that exercise training improves diastolic function in these patients...

STUDY DESIGN: Cross-sectional research design. INTRODUCTION: Active range of motion (AROM) is used as indicator of hand function. However, functional range of motion (FROM) data are limited, and fail to represent activities of daily living (ADL). PURPOSE OF THE STUDY: To estimate dominant hand FROM in flexion, abduction and palmar arching in people under 50 years of age performing ADL. METHODS: AROMs and hand postures in 24 representative ADL of the International Classification of Functioning, Disability and Health (ICF) were recorded in 12 men and 12 women...

Heart and respiration rates can be wirelessly measured by extracting the phase shift caused by the periodic displacement of a patient's chest wall. We have developed a phased-array Doppler-based non-contact vital sign (NCVS) sensor capable of long-term vital signs monitoring using an automatic patient tracking and movement detection algorithm. Our NCVS sensor achieves non-contact heart rate monitoring with accuracies of over 90% (i.e, within ±5 Beats-Per-Minute vs. a reference sensor) across a large number of data points collected over various days of the week inside a typical office cubicle setting at a distance of 1...

OBJECTIVE: To review the literature concerning the effects of salpingectomy on ovarian function as assessed using measures of ovarian reserve and outcomes from in-vitro fertilization and spontaneous pregnancy cycles. BACKGROUND: Tubal surgery is performed for a variety of indications in gynecology. Salpingectomy is the most aggressive form of tubal surgery and may be performed for potential risk reduction for epithelial ovarian cancer, sterilization, ectopic pregnancy and as a method to enhance fertility in the setting of a hydrosalpinx...

The objective of this study was to compare subtypes of Campylobacter jejuni and Campylobacter coli detected on three selective Campylobacter plating media to determine whether each medium selected for different subtypes. Fifty ceca and 50 carcasses (representing 50 flocks) were collected from the evisceration line in a commercial broiler processing plant. Campylobacter was cultured and isolated from cecal contents and carcass rinses on Campy-Cefex, Campy Line, and RF Campylobacter jejuni/coli agars. When a positive result was obtained with all three media, one colony of the most prevalent morphology on each medium was selected for further analysis by full genome sequencing and multilocus sequence typing...

BACKGROUND: Acne vulgaris is common and can significantly impair quality of life, yet little is known about patients' understanding of acne and its treatments. Oral antibiotics are widely used for acne, despite concerns about antibiotic resistance. People are increasingly turning to online discussion forums for advice and information on these sites may influence health beliefs and treatment adherence. OBJECTIVE: To explore understandings about the use of oral antibiotics for acne and advice shared amongst messages posted on online forums...

This work was intended to develop self-assembly lipids for incorporating G-protein coupled receptors (GPCRs) in order to improve the success rate for nuclear magnetic resonance spectroscopy (NMR) structural elucidation. We hereby report the expression and purification of uniformly (15)N-labeled human cannabinoid receptor-2 domain in insect cell media. The domain was refolded by screening several membrane mimetic environments. Different q ratios of isotropic bicelles were screened for solubilizing transmembrane helix 6, 7 and 8 (TMH67H8)...

Tide pools habitats are naturally exposed to a high degree of environmental variability. The consequences of living in these extreme habitats are not well established. In particular, little it is known about of the effects of hypercanic seawater (i.e. high pCO2 levels) on marine vertebrates such as intertidal pool fish. The aim of this study was to evaluate the effects of increased pCO2 on the physiology and behavior in juveniles of the intertidal pool fish Girella laevifrons. Two nominal pCO2 concentrations (400 and 1600μatm) were used...

Phosphate capture from aqueous was conducted using hydrous zirconium oxide (HZO) embedded in quaternary-ammonium Chinese reed (CR-N(+)-HZO), and the characteristics of adsorbent was determined. HZO was dispersed as nanoparticles or nano-clusters on the external or inside the networking pores of CR-N(+)-HZO. The surface of CR-N(+)-HZO was heterogeneous with multiple adsorption sites, HZO nanocomposite and N(+)(CH2CH3)3Cl(-), which both contributed to the adsorption process. The phosphate uptake by CR-N(+)-HZO was optimal at pH 3...

Poly (ADP-ribose) polymerase 1 (PARP-1) has a central role in the repair of DNA breaks and is a promising treatment target in malignancy. We measured PARP1 mRNA levels by a SYBR-green-based PCR in the bone marrow of 74 patients with myelodysplastic syndrome (MDS) and correlated them to their demographic, hematologic and prognostic characteristics. The median PARP1 mRNA levels were correlated to the type of MDS (2008/2016 WHO classification, P=0.005) and to the IPSS score (P=0.002). A correlation was also found with the IPSS-R score (P=0...

We describe a mechanism by which nonlinear phononics allows ultrafast coherent and directional control of transient structural distortions. With ErFeO_{3} as a model system, we use density functional theory to calculate the structural properties as input into an anharmonic phonon model that describes the response of the system to a pulsed optical excitation. We find that the trilinear coupling of two orthogonal infrared-active phonons to a Raman-active phonon causes a transient distortion of the lattice. In contrast to the quadratic-linear coupling that has been previously explored, the direction of the distortion is determined by the polarization of the exciting light, introducing a novel mechanism for nonlinear phononic switching...

BACKGROUND: Genome-wide association studies have so far identified 56 loci associated with risk of coronary artery disease (CAD). Many CAD loci show pleiotropy; that is, they are also associated with other diseases or traits. OBJECTIVES: This study sought to systematically test if genetic variants identified for non-CAD diseases/traits also associate with CAD and to undertake a comprehensive analysis of the extent of pleiotropy of all CAD loci. METHODS: In discovery analyses involving 42,335 CAD cases and 78,240 control subjects we tested the association of 29,383 common (minor allele frequency >5%) single nucleotide polymorphisms available on the exome array, which included a substantial proportion of known or suspected single nucleotide polymorphisms associated with common diseases or traits as of 2011...
