Physical examination for the diagnosis of cervical facet joint pain : A systematic review
Authors: Mansfield M 
Published: July 2014

Background: Chronic neck and low back pain are painful, disabling and are associated with significant costs to individuals and health services. The evidence base to date is inconclusive in determining which physical examination tests are accurate in identifying facet joint pain and further research is required. The objective of this study was to undertake a systematic review investigating the accuracy of a physical examination to identify facet joint pain. Methods: Medline, Embase, CINAHL, PubMed, Central, Amed, Biosis, and Mantis were searched up to 2012. Grey literature, conference proceedings, hand-searching and expert author contact were also undertaken. Studies were included if the subjects were adults over the age of 18 years, had no red flag pathologies or previous surgery and were in English. There were no restrictions on the study type. The included studies were assessed for bias using QUADAS-2. Results: A total of 13 914 studies were retrieved and screened for inclusion. Four cervical and six lumbar spine studies met the inclusion criteria. No additional lumbar spine studies were retrieved since 2007; therefore, the lumbar spine studies were not analysed. The cervical spine studies were heterogeneous in methods and a meta anaylsis could not be conducted. Two studies investigated a combined manual examination. One study investigated palpation in isolation and another investigated electronic pain pressure thresholds. The accuracy values for all cervical spine studies were 0.67–1.00 and 0.16–1.00 for sensitivity and specificity respectively. Conclusions: This review cannot provide conclusive evidence for the diagnostic accuracy of physical examination in diagnosing facet joint pain in the cervical spine. There was a small trend towards higher accuracy values when using a combined manual examination including palpation. However, caution should be taken as this is based on very few studies that were highly heterogeneous. Implications: Further research is needed in different clinical settings, including in primary care and with subjects with less chronicity of symptoms. Moreover, greater homogeneity of the methods used in index and reference tests is required in future studies.
The 2011 World Press Photo: A study of a modern-day Hagar in Yemen through the prism of collective memory in Islam
Authors: Mielczarek Natalia 
Published: July 2014

Abstract
This project offers historical and visual rhetorical analyses of the 2011 World Press Photo, arguing the award-winning image echoes one of the most central collective memories within Islam: that of Hagar, the mother of all Arabs. The article posits that the woman in the photo is the modern-day Hagar who exemplifies strength, courage and independence, much like her predecessor millennia ago. In that, the woman, as captured in the winning image, creates a countermemory to the dominant collective memory of a Muslim woman in Yemen, who has emerged over the years as dominated by men and in need of protection. The analysis puts the 2011 World Press Photo within the Islam-centric context of interpretation, suggesting that looking at it only through the Christian-centred perspective, as was done in the West, robs the image of its polysemic qualities.
Manufacturing method of carbon and glass fabric composites with dispersed nanofibers using vacuum-assisted resin transfer molding
Authors: Song Jun Hee 
Published: July 2014

AbstractFiber-reinforced composites have favorable structural characteristics such as their light weight, high specific strength, and high stiffness. Vacuum-assisted resin transfer molding (VARTM), used for manufacturing these composites, is relatively simple and provides materials with excellent mechanical properties. In this study, the author investigated the utility of VARTM in improving the performance of a carbon nanofiber (CNF)/carbon fiber composite impregnated with thermosetting resin. Processing parameters were determined, and the integrity of the manufactured composites was assessed. Carbon and glass fibers were used as reinforcing materials in an epoxy resin matrix. CNFs, which have excellent thermal and electrical characteristics, were dispersed in the composites. The pore sizes using the 0°/90°- and 90°/45° types of laminates were about 45 and 50 μm, respectively. The integrated composites produced had low porosity (below 3.7×10-5%).

of the field-induced

The Yang–Lee zero approach clearly shows the field-induced Kosterlitz–Thouless transition
and the critical magnetic field agrees well with the results from other indirect methods.
Also, the reduced zero-field susceptibility gives us the same conclusion.
For the investigations, we used the exact and approximate ground densities

(up to 9×9 lattices) and the Wang–Landau Monte Carlo algorithm for large systems
(up to 30×30 lattices).
Targeted and reversible cancer cell-binding DNA nanoparticles
Authors: Ruff Laura E. , Marciniak Jennifer Y. , Sanchez Ana B. , Esener Sadik C. , Messmer Bradley T. 
Published: July 2014

AbstractDNA nanoparticles (DeNAno) produced by rolling circle replication of circular oligonucleotide templates are a novel format for the selection of cell-binding reagents from randomized libraries. DeNAno particles consist of several hundred concatemers and can leverage that multivalency to bind to complex surfaces such as cells. In this study, an iterative bio-panning approach was used to recover particles that bound to the mouse pancreatic cancer line, Panc-02. These particles shared a primary sequence motif. Hybridization of a locked nucleic acid complimentary to this motif both inhibited cell binding and released pre-bound DeNAno particles from the cells. The monomeric form of one of the selected sequences was unable to compete with the cognate particle, consistent with a low-affinity, but high-avidity, type interaction. DeNAno library selection against cancer or other cell types can, thus, yield novel cell binding agents without
In situ Crystallization of N(SiMe3)3 and As(SiMe3)3: Trigonal planar or pyramidal coordination of the central atoms?

Published: July 2014

Abstract

In situ crystallization technique at low temperature was used to obtain single crystals of the low melting compounds N(SiMe3)3
1 and As(SiMe3)3
3. N(SiMe3)3 has a waxy consistence at room temperature. The solid-state structure of both compounds has been determined by single-crystal X-ray diffraction analysis. N(SiMe3)3 is distorted and shows nearly a trigonal planar coordination of the central nitrogen atom. In contrast, the heavier homologue As(SiMe3)3 shows a trigonal pyramidal coordination with Si-As-Si 103.4(6)°–104.9(6)°.
Micro- and Nano-Characteration of Interaction Between Asphalt and Filler
Authors: Tan Yiqiu , Guo Meng 
Published: July 2014

AbstractThis study explored the testing technologies characterizing the interaction between asphalt and filler. An atomic force microscope (AFM) was used to describe the surface morphology and surface adhesion force of asphalt mastic and analyze their effect factors. Fourier transform infrared spectroscopy (FTIR) was used to analyze the physicochemical interaction between asphalt and filler. Adsorption tests were used to study adsorption and desorption properties of asphalt on aggregate. The results show that andesite aggregate had a smoother surface and a weaker adhesion force than granite aggregate. The greater the asphalt penetration, the stronger the surface adhesion force. A small number of filler material increased the adhesion force of the asphalt mastic, but too much filler decreased the adhesion force. FTIR tests were employed to explore the various functional groups of asphalt and fillers. No obvious new stretching vibration peak or deformation vibration peak indicated that the interaction between asphalt and filler was mainly a physical action. Net absorption test revealed that the greater the equilibrium concentration, the greater the adsorption amount. Distilled water stripped asphalt from aggregate. The type of adsorption isotherm corresponded to multi-molecular layer adsorption that further indicated that the interaction between asphalt and fillers was mainly a physical action.
Effects of Using Recycled Asphalt Shingles in Open-Graded Friction Course on Flexible Pavement Performance
Authors: Wang Yuhong , Wang George , Ahn Yong Han 
Published: July 2014

Abstract
Recycling inert construction wastes is one of the approaches to promote sustainable development. In North America, the majority of steep roofs are covered with asphalt shingles. Re-roofing and manufacturing of asphalt shingles create a large amount of waste. This paper examines the use of recycled asphalt shingles (RAS) in open-graded friction course (OGFC). OGFC mixtures with and without RAS were prepared and tested for rutting resistance, indirect tensile strength, moisture-induced damage, and dynamic modulus. The dynamic modulus was also used to examine the responses of flexible pavement under assumed structures, temperature levels, and loading conditions. In addition, a section of major interstate highway in the United States surfaced with the RAS OGFC mixture of this study was used for performance monitoring. The use of RAS in OGFC was found to enhance its rutting performance, generally increase indirect tensile strengths of the tested specimens, generate pavement structural responses similar to those of a conventional OGFC mixture under the same loading conditions, and improve pavement’s fatigue life. Except for clogging, no obvious distress was found in the trial section after being used for two and a half years. Future research is suggested for the development of an appropriate laboratory evaluation method for the assessment of OGFC durability.
Ploidy-Regulated Variation in Biofilm-Related Phenotypes in Natural Isolates of Saccharomyces cerevisiae
Authors: Hope Elyse A , Dunham Maitreya J 
Published: July 2014

Abstract
The ability of yeast to form biofilms contributes to better survival under stressful conditions. We see the impact of yeast biofilms and “flocs” (clumps) in human health and industry, where forming clumps enables yeast to act as a natural filter in brewing and forming biofilms enables yeast to remain virulent in cases of fungal infection. Despite the importance of biofilms in yeast natural isolates, the majority of our knowledge about yeast biofilm genetics comes from work with a few tractable laboratory strains. A new collection of sequenced natural isolates from the Saccharomyces Genome Resequencing Project enabled us to examine the breadth of biofilm-related phenotypes in geographically, ecologically, and genetically diverse strains of Saccharomyces cerevisiae. We present a panel of 31 haploid and 24 diploid strains for which we have characterized six biofilm-related phenotypes: complex colony morphology, complex mat formation, flocculation, agar invasion, polystyrene adhesion, and psuedohyphal growth. Our results show that there is extensive phenotypic variation between and within strains, and that these six phenotypes are primarily uncorrelated or weakly correlated, with the notable exception of complex colony and complex mat formation. We also show that the phenotypic strength of these strains varies significantly depending on ploidy, and the diploid strains demonstrate both decreased and increased phenotypic strength with respect to their haploid counterparts. This is a more complex view of the impact of ploidy on biofilm-related phenotypes than previous work with laboratory strains has suggested, demonstrating the importance and enormous potential of working with natural isolates of yeast.

Abstract

Background.
We investigated the association between diabetes mellitus (DM) and the prognosis of patients with early colon cancer who had undergone curative surgery.

Methods.
From three national databases of patients in Taiwan, we selected a cohort of colon cancer patients who had been newly diagnosed with stage I or stage II colon cancer between January 1, 2004 and December 31, 2008 and had undergone curative surgery. We collected information regarding DM (type 2 DM only), the use of antidiabetic medications, other comorbidities, and survival outcomes. The colon cancer-specific survival (CSS) and the overall survival (OS) were compared between patients with and without DM.

Results.
We selected 6,937 colon cancer patients, among whom 1,371 (19.8%) had DM. The colon cancer patients with DM were older and less likely to receive adjuvant chemotherapy but had a similar tumor stage and grade, compared with colon cancer patients without DM. Compared with colon cancer patients without DM, patients with DM had significantly shorter OS (5-year OS: 71.0% vs. 81.7%) and CSS (5-year CSS: 86.7% vs. 89.2%). After adjusting for age, sex, stage, adjuvant chemotherapy, and comorbidities in our multivariate analysis, DM remained an independent prognostic factor for overall mortality (adjusted hazards ratio: 1.32, 95% confidence interval: 1.18–1.49), but not for cancer-specific mortality. Among the colon cancer patients who had received antidiabetic drug therapy, patients who had used insulin had significantly shorter CSS and OS than patients who had not.

Conclusion.
Among patients who receive curative surgery for early colon cancer, DM is a predictor of increased overall mortality.
Concentrations of stromal cell-derived factor-1 in serum, plasma, and synovial fluid of horses with osteochondral injury
Authors: Dymock David C. , Brown Murray P. , Merritt Kelly A. , Trumble Troy N. 
Published: July 2014

Abstract
Objective—To determine whether stromal cell-derived factor-1 (SDF-1) concentrations in serum, plasma, and synovial fluid differed among untrained, race-trained, and osteochondral-injured Thoroughbred racehorses.
Animals—22 racehorses without osteochondral injury and 37 racehorses with osteochondral injury.
Procedures—Horses without osteochondral injury were examined before and after 5 to 6 months of race training. Horses with osteochondral injury were undergoing arthroscopic surgery for removal of osteochondral fragments from carpal or metacarpophalangeal or metatarsophalangeal joints (fetlock joints). Serum, plasma, and fetlock or carpal synovial fluid samples were obtained and analyzed for SDF-1 concentration by use of an ELISA.
Results—In horses with fetlock or carpal joint injury, mean synovial fluid SDF-1 concentrations were significantly higher, serum SDF-1 concentrations were significantly lower, and synovial fluid-to-serum SDF-1 ratios were significantly higher than in untrained and trained horses. Synovial fluid SDF-1 concentrations were not significantly different between trained and untrained horses. Plasma SDF-1 concentrations were not different among the 3 groups. Results obtained with serum, compared with synovial fluid and plasma, had better sensitivity for differentiating between osteochondral-injured horses and uninjured horses. In horses with fetlock joint osteochondral injury, serum SDF-1 concentrations were correlated with radiographic and arthroscopic inflammation scores, but not arthroscopic cartilage scores.
Conclusions and Clinical Relevance—Results suggested that serum SDF-1 concentrations were more sensitive than plasma and synovial fluid concentrations for detection of osteochondral injury in the fetlock or carpal joint of racehorses. Analysis of serum and synovial SDF-1 concentrations in horses with experimentally induced joint injury may help define the onset and progression of post-traumatic osteoarthritis and aid in the evaluation of anti-inflammatory treatments.
Evaluation of tranexamic acid and ϵ-aminocaproic acid concentrations required to inhibit fibrinolysis in plasma of dogs and humans
Authors: Fletcher Daniel J. , Blackstock Kelly J. , Epstein Kira , Brainard Benjamin M. 
Published: July 2014

Abstract
Objective—To determine minimum plasma concentrations of the antifibrinolytic agents tranexamic acid (TEA) and ϵ-aminocaproic acid (EACA) needed to completely inhibit fibrinolysis in canine and human plasma after induction of hyperfibrinolysis.
Samples—Pooled citrated plasma from 7 dogs and commercial pooled citrated human plasma.
Procedures—Concentrations of EACA from 0 μg/mL to 500 μg/mL and of TEA from 0 μg/mL to 160 μg/mL were added to pooled citrated canine and human plasma. Hyperfibrinolysis was induced with 1,000 units of tissue plasminogen activator/mL, and kaolin-activated thromboelastography was performed in duplicate. The minimum concentrations required to completely inhibit fibrinolysis 30 minutes after maximum amplitude of the thromboelastography tracing occurred were determined.
Results—Minimum plasma concentrations necessary for complete inhibition of fibrinolysis by EACA and TEA in pooled canine plasma were estimated as 511.7 μg/mL (95% confidence interval [CI], 433.2 to 590.3 μg/mL) and 144.7 μg/mL (95% CI, 125.2 to 164.2 μg/mL), respectively. Concentrations of EACA and TEA necessary for complete inhibition of fibrinolysis in pooled human plasma were estimated as 122.0 μg/mL (95% CI, 106.2 to 137.8 μg/mL) and 14.7 μg/mL (95% CI, 13.7 to 15.6 μg/mL), respectively.
Conclusions and Clinical Relevance—Results supported the concept that dogs are hyperfibrinolytic, compared with humans. Higher doses of EACA and TEA may be required to fully inhibit fibrinolysis in dogs.
Comparison of air sac volume, lung volume, and lung densities determined by use of computed tomography in conscious and anesthetized Humboldt penguins (Spheniscus humboldti) positioned in ventral, dorsal, and right lateral recumbency

Published: July 2014

Abstract
Objective—To determine the effects of recumbency on air sac volume, lung volume, and lung densities in CT images of healthy, conscious and anesthetized spontaneously breathing Humboldt penguins (Spheniscus humboldti).
Animals—25 adult (13 male and 12 female) Humboldt penguins.
Procedures—CT images of conscious penguins in ventral recumbency and anesthetized penguins in dorsal, ventral, and right lateral recumbency were obtained. Air sac volume, lung volume, and lung densities in CT images were calculated. A paired samples t test was used to determine whether right and left lung densities differed among recumbencies. Repeated-measures ANOVA (controlled for sex and order of recumbencies during CT) was used to determine whether air sac or lung volumes differed among recumbencies.
Results—Recumbency had a significant effect on air sac volume but not lung volume. Air sac volume was largest in conscious penguins in ventral recumbency (mean ± SD, 347.2 ± 103.1 cm3) and lowest in anesthetized penguins in dorsal recumbency (median, 202.0 cm3; 10th to 90th percentile, 129.2 to 280.3 cm3). Lung densities were highest in anesthetized penguins in dorsal recumbency (right lung median, 0.522 g/cm3; left lung median, 0.511 g/cm3) and lowest in anesthetized penguins in ventral recumbency (right lung median, 0.488 g/cm3; left lung median, 0.482 g/cm3).
Conclusions and Clinical Relevance—Results indicated that anesthetized Humboldt penguins had the lowest air sac volume and highest lung densities in dorsal recumbency. Therefore, this recumbency may not be recommended. Minimal changes in lung volume were detected among recumbencies or between conscious and anesthetized penguins.
Correlation of diffusion tensor tractography and intraoperative macrostimulation during deep brain stimulation for Parkinson disease

Published: July 2014

Object
The purpose of this study was to investigate whether diffusion tensor imaging (DTI) of the corticospinal tract (CST) is a reliable surrogate for intraoperative macrostimulation through the deep brain stimulation (DBS) leads. The authors hypothesized that the distance on MRI from the DBS lead to the CST as determined by DTI would correlate with intraoperative motor thresholds from macrostimulations through the same DBS lead.

Methods
The authors retrospectively reviewed pre- and postoperative MRI studies and intraoperative macrostimulation recordings in 17 patients with Parkinson disease (PD) treated by DBS stimulation. Preoperative DTI tractography of the CST was coregistered with postoperative MRI studies showing the position of the DBS leads. The shortest distance and the angle from each contact of each DBS lead to the CST was automatically calculated using software-based analysis. The distance measurements calculated for each contact were evaluated with respect to the intraoperative voltage thresholds that elicited a motor response at each contact.

Results
There was a nonsignificant trend for voltage thresholds to increase when the distances between the DBS leads and the CST increased. There was a significant correlation between the angle and the voltage, but the correlation was weak (coefficient of correlation [R] = 0.36).

Conclusions
Caution needs to be exercised when using DTI tractography information to guide DBS lead placement in patients with PD. Further studies are needed to compare DTI tractography measurements with other approaches such as microelectrode recordings and conventional intraoperative MRI–guided placement of DBS leads.
