Abstract

Background and aims
Affect balance reflects relative levels of negative affect (NA) and positive affect (PA) and includes four styles: Healthy (low NA/high PA), Depressive (high NA/low PA), Reactive (high NA/high PA) and Low (low NA/low PA). These affect balance styles may have important associations with clinical outcomes in patients with fibromyalgia. Herein, we evaluated the severity of core fibromyalgia symptom domains as described by the Outcomes Research in Rheumatology-Fibromyalgia working group in the context of the four affect balance styles.

Methods
Data from 735 patients with fibromyalgia who completed the Brief Pain Inventory, Multidimensional Fatigue Inventory, Profile of Mood States, Medical Outcomes Sleep Scale, Multiple Ability Self-Report Questionnaire, Fibromyalgia Impact Questionnaire-Revised, Medical Outcomes Study Short Form-36, and Positive and Negative Affect Schedule were included in this analysis.

Results
The majority (51.8%) of patients in our sample had a Depressive affect balance style; compared to patients with a Healthy affect balance style, they scored significantly worse in all fibromyalgia symptom domains including pain, fatigue, sleep disturbance, dyscognition, depression, anxiety, stiffness, and functional status (P = <.001 to .004). Overall, patients with a Healthy affect balance style had the lowest level of symptoms, while symptom levels of those with Reactive and Low affect balance styles were distributed in between those of the Depressive and Healthy groups.

Conclusions and implications
The results of our cross-sectional study suggest that having a Healthy affect balance style is associated with better physical and psychological symptom profiles in fibromyalgia. Futures studies evaluating these associations longitudinally could provide rationale for evaluating the effect of psychological interventions on affect balance and clinical outcomes in fibromyalgia.

Published: June 2014

Let $A$ be a finite alphabet and $f:~A^{\ast }\rightarrow A^{\ast }$ be a morphism with an iterative fixed point $f^{{\it\omega}}({\it\alpha})$, where ${\it\alpha}\in A$. Consider the subshift $({\mathcal{X}},T)$, where ${\mathcal{X}}$ is the shift orbit closure of $f^{{\it\omega}}({\it\alpha})$ and $T:~{\mathcal{X}}\rightarrow {\mathcal{X}}$ is the shift map. Let $S$ be a finite alphabet that is in bijective correspondence via a mapping $c$ with the set of non-empty suffixes of the images $f(a)$ for $a\in A$. Let ${\mathcal{S}}\subset S^{\mathbb{N}}$ be the set of infinite words $\mathbf{s}=(s_{n})_{n\geq 0}$ such that ${\it\pi}(\mathbf{s}):=c(s_{0})f(c(s_{1}))f^{2}(c(s_{2}))\cdots \in {\mathcal{X}}$. We show that if $f$ is primitive, $f^{{\it\omega}}({\it\alpha})$ is aperiodic, and $f(A)$ is a suffix code, then there exists a mapping $H:~{\mathcal{S}}\rightarrow {\mathcal{S}}$ such that $({\mathcal{S}},H)$ is a topological dynamical system and ${\it\pi}:~({\mathcal{S}},H)\rightarrow ({\mathcal{X}},T)$ is a conjugacy; we call $({\mathcal{S}},H)$ the suffix conjugate of $({\mathcal{X}},T)$. In the special case where $f$ is the Fibonacci or Thue–Morse morphism, we show that the subshift $({\mathcal{S}},T)$ is sofic, that is, the language of ${\mathcal{S}}$ is regular.

Published: June 2014

AbstractObjectives:To compare chronic suppurative otitis media prevalence in rural and urban primary school children in Bangladesh, and to determine its relationship with specific sociodemographic factors.Methods:In this cross-sectional survey, 681 rural primary school children from Shibpur upazilla, Narsingdi district, and 964 urban primary school children from Dhaka Metropolitan City, underwent an ENT check-up by doctors trained in ENT. Their parents or guardians were interviewed with regard to their sociodemographic status and other related issues using a pre-tested protocol.Results:In this study, 6.02 per cent of the rural primary school children and 2.07 per cent of the urban primary school children had chronic suppurative otitis media. (Overall, 3.71 per cent of the children had the disorder.) The disorder was slightly more prevalent among girls than boys in both rural (6.05vs5.98 per cent) and urban (2.33vs1.82 per cent) communities. There was a significant association between the presence of chronic suppurative otitis media in children and: parents' or guardians' occupation and their annual income, housing type, family size, maternal education, and bathing habit.Conclusion:Improvement of associated sociodemographic factors would reduce the prevalence and resultant complications of chronic suppurative otitis media in primary school children in developing countries.

Concern has been expressed over future biogeographical expansion and habitat capitalization by species of the phylum Cnidaria, as this may have negative implications on human activities and ecosystems. There is, however, a paucity of knowledge and understanding of jellyfish ecology, in particular species distribution and seasonality. Recent studies in the UK have principally focused on the Celtic, Irish and North Seas, but all in isolation. In this study we analyse data from a publicly-driven sightings scheme across UK coastal waters (2003–2011; 9 years), with the aim of increasing knowledge on spatial and temporal patterns and trends. We describe inter-annual variability, seasonality and patterns of spatial distribution, and compare these with existing historic literature. Although incidentally-collected data lack quantification of effort, we suggest that with appropriate data management and interpretation, publicly-driven, citizen-science-based, recording schemes can provide for large-scale (spatial and temporal) coverage that would otherwise be logistically and financially unattainable. These schemes may also contribute to baseline data from which future changes in patterns or trends might be identified. We further suggest that findings from such schemes may be strengthened by the inclusion of some element of effort-corrected data collection.
Choice of handedness and automated suturing for anthropomorphic dual-arm surgical robots
Authors: Ding Jienan , Simaan Nabil 
Published: June 2014

SUMMARYLaparoscopic and Single Port Access Surgery (SPAS) present unique dexterity challenges related to dual-arm operations in confined spaces and tele-manipulation of highly dexterous surgical slaves. In an effort to reduce tele-manipulation burden, new paradigms for semi-automating surgical tasks are needed. This paper presents a new minimal constraint suturing and automated choice of handedness for anthropomorphic dual-arm robots. The automated choice of handedness supports surgeons during tele-manipulation of complex robotic slaves where dexterity and workspace constraints are difficult to learn. This criterion is also used to support automated dual-arm rendezvous for quicker suture exchange during dual-arm suturing. The minimal constraint algorithm presented in this paper allows surgeons to operate within a shared-control tele-manipulation framework whereby the surgeon controls the needle insertion speed and the robot controls the needle orientation while respecting a minimalistic set of tissue constraints. This framework is evaluated on a novel insertable robotic end-effectors platform for SPAS. A simulation study demonstrates the effectiveness of the automated choice of handedness criterion through a study of dexterity limitations of each arm. Additional simulations show the proposed algorithm for automated rendezvous and suture exchange.

Published: June 2014

Objectives: The aim of this study was to estimate direct and indirect excess costs attributable to stroke in Sweden in 2009 and to compare these with similar estimates from 1997.Methods: Data on first-ever stoke admissions in the first half of 2009 from the Swedish national stroke register (RS) were used for cost calculations and compared with results from 1997 also using RS data. A societal perspective was taken including the acute and follow-up phase, rehabilitation, stroke re-admissions, drugs, home- and residential care services for activities of daily life (ADL) support, and indirect costs for premature death and productivity losses (2009 prices). Survival was extrapolated to estimate the lifetime present value cost of stroke.Results: The societal lifetime present value cost for stroke in 2009 was €68,800 per patient (ADL support: 59 percent; productivity losses: 21 percent). Women had higher costs than men in all age groups as a result from greater need for ADL support. Patients treated at a stroke unit indicated low incremental cost per life-year gained compared with those who had not. The total lifetime cost increased between 1997 and 2009. Hospitalization costs per patient were stable, while long-term costs for home- and residential care services increased.Conclusions: Changes in patient characteristics, longer expected survival, and possibly in the Swedish stroke care, have led to higher annual and lifetime costs per patient in 2009 compared with 1997. A comprehensive national stroke care performance register like RS may be suitable for health economic assessments.

AbstractThis study describes the first use of concurrent high-precision temperature and drip rate monitoring to explore what controls the temperature of speleothem forming drip water. Two contrasting sites, one with fast transient and one with slow constant dripping, in a temperate semi-arid location (Wellington, NSW, Australia), exhibit drip water temperatures which deviate significantly from the cave air temperature. We confirm the hypothesis that evaporative cooling is the dominant, but so far unattributed, control causing significant disequilibrium between drip water and host rock/air temperatures. The amount of cooling is dependent on the drip rate, relative humidity and ventilation. Our results have implications for the interpretation of temperature-sensitive, speleothem climate proxies such as δ18O, cave microecology and the use of heat as a tracer in karst. Understanding the processes controlling the temperature of speleothem-forming cave drip waters is vital for assessing the reliability of such deposits as archives of climate change.

Published: June 2014

AbstractGlass is a freezing phase of a deeply supercooled liquid. Despite its simple definition, the origin of glass forming ability (GFA) is still ambiguous, even for binary Cu-Zr alloys. Here, we directly study the stability of the supercooled Cu-Zr liquids where we find that Cu64Zr36 at a supercooled temperature shows deeper undercoolability and longer persistence than other neighbouring compositions with an equivalent driving Gibbs free energy. This observation implies that the GFA of the Cu-Zr alloys is significantly affected by crystal-liquid interfacial free energy. In particular, the crystal-liquid interfacial free energy of Cu64Zr36 in our measurement was higher than that of other neighbouring liquids and, coincidently a molecular dynamics simulation reveals a larger glass-glass interfacial energy value at this composition, which reflects more distinct configuration difference between liquid and crystal phase. The present results demonstrate that the higher crystal-liquid interfacial free energy is a prerequisite of good GFA of the Cu-Zr alloys.

Published: June 2014

Abstract
Nonlethal methods are needed to assess the health of wild fish and quantify the robustness of the broader population. Results could be used to indicate exposure to various stressors, such as contaminants, infectious disease, external parasite loads, and fishing pressure, to monitor changes in fish population health over time. The wild Red Drum Sciaenops ocellatus population in the Kennedy Space Center Reserve of Merritt Island National Wildlife Refuge was used to develop a protocol to define the health of free-ranging fish using nonlethal techniques. This health index incorporated morphometric measurements, weight, an evaluation for external parasite fauna, notation of physical deformities, and the presence of lesions. A total of 126 adult Red Drum were collected using hook-and-line angling during prespawning (May), spawning (September and October), and postspawning (December) periods. All fish were released alive back into their environment. The nonlethal health assessment scored fish in the “healthy” range of the health index during the prespawning and spawning periods. Fish caught during the postspawning period scored slightly below this range. Parasite load contributed to the depressed score during the postspawning period. Fish collected in all sampling periods were rated on average as “excellent” for condition factor, which suggests that the sampled population in the reserve were thriving.

Published: June 2014

Abstract
High-fat diets may have favorable effects on growth, partly based on protein sparing, but high-fat diets often lead to fatty liver (excessive fat deposition in the liver), which may be deleterious to fish growth and health. The goal of this study was therefore to investigate possible adverse effects and how they develop. Juvenile Blunt Snout Bream Megalobrama amblycephala (initial weight ± SE = 17.70 ± 0.10 g) were fed two diets (5% fat [control] or 15% fat). After 8 weeks, fish that were fed the 15% fat diet showed a high rate of mortality and poor growth. The histological results clearly showed that the high fat intake resulted in fat and glycogen accumulation and structural alterations of the hepatocytes, mitochondria, and nuclei. In the high-fat group, impairments of the mitochondria included mitochondrial swelling and the loss of cristae and matrix. Fish that were given the 15% fat diet exhibited low succinate dehydrogenase and Na+,K+-ATPase activities and increased cytochrome-c release from the mitochondria. Expression of genes for complex I and III subunits of the mitochondrial respiratory chain were down-regulated in fish that received the high-fat diet. Increases in malondialdehyde level and the ratio of oxidized glutathione to reduced glutathione suggested oxidative stress in the livers of fish from the high-fat diet group. Moreover, the lower leukocyte count, lysozyme and alternative complement activities, and globulin level in fish that received the high-fat diet indicated suppressive immune responses. Overall, the intake of excessive fat impaired mitochondrial bioenergetics and physiological functions. The dysfunction of the mitochondria subsequently mediated oxidative stress and hepatocyte apoptosis, which in turn led to the reduced efficacy of the immune system.

Published: June 2014

AbstractThe t(1; 11) translocation appears to be the causal genetic lesion with 70% penetrance for schizophrenia, major depression, and other psychiatric disorders in a Scottish family. Molecular studies identified the disruption of the DISC1 (disrupted-in-schizophrenia 1) gene by chromosome translocation at chromosome 1q42. Our previous studies, however, revealed that the translocation also disrupted another gene, Boymaw (also termed DISC1FP1), on chromosome 11. After translocation, two fusion genes (the DISC1-Boymaw (DB7) and the Boymaw-DISC1 (BD13)) are generated between the DISC1 and Boymaw genes. In the present study, we report that expression of the DB7 fusion gene inhibits both intracellular NADH oxidoreductase activities and protein translation. We generated humanized DISC1-Boymaw mice with gene targeting to examine thein vivofunctions of the fusion genes. Consistent with thein vitrostudies on the DB7 fusion gene, protein translation activity is decreased in the hippocampus and in cultured primary neurons from the brains of the humanized mice. Expression of Gad67, Nmdar1, and Psd95 proteins are also reduced. The humanized mice display prolonged and increased responses to the NMDA receptor antagonist, ketamine, on various mouse genetic backgrounds. Abnormal information processing of acoustic startle and depressive-like behaviors are also observed. In addition, the humanized mice display abnormal erythropoiesis, which was reported to associate with depression in humans. Expression of the DB7 fusion gene may reduce protein translation to impair brain functions and thereby contribute to the pathogenesis of major psychiatric disorders.
Boymaw, Overexpressed in Brains with Major Psychiatric Disorders, May Encode a Small Protein to Inhibit Mitochondrial Function and Protein Translation
Authors: Ji Baohu , Kim Minjung , Higa Kerin K. , Zhou Xianjin 
Published: June 2014

AbstractThe t(1,11) chromosome translocation co-segregates with major psychiatric disorders in a large Scottish family. The translocation disrupts the DISC1 and Boymaw (DISC1FP1) genes on chromosomes 1 and 11, respectively. After translocation, two fusion genes are generated. Our recent studies found that the DISC1-Boymaw fusion protein is localized in mitochondria and inhibits oxidoreductase activity, rRNA expression, and protein translation. Mice carrying the DISC1-Boymaw fusion genes display intermediate behavioral phenotypes related to major psychiatric disorders. Here, we report that the Boymaw gene encodes a small protein predominantly localized in mitochondria. The Boymaw protein inhibits oxidoreductase activity, rRNA expression, and protein translation in the same way as the DISC1-Boymaw fusion protein. Interestingly, Boymaw expression is up-regulated by different stressors at RNA and/or protein translational levels. In addition, we found that Boymaw RNA expression is significantly increased in the postmortem brains of patients with major psychiatric disorders. Our studies therefore suggest that the Boymaw gene is a potential susceptibility gene for major psychiatric disorders in both the Scottish t(1,11) family and the general population of patients.

Abstract
Genome-wide association studies have been successful in identifying genes involved in polygenic traits and are valuable for crop improvement. Tomato (Solanum lycopersicum) is a major crop and is highly appreciated worldwide for its health value. We used a core collection of 163 tomato accessions composed of S. lycopersicum, S. lycopersicum var cerasiforme, and Solanum pimpinellifolium to map loci controlling variation in fruit metabolites. Fruits were phenotyped for a broad range of metabolites, including amino acids, sugars, and ascorbate. In parallel, the accessions were genotyped with 5,995 single-nucleotide polymorphism markers spread over the whole genome. Genome-wide association analysis was conducted on a large set of metabolic traits that were stable over 2 years using a multilocus mixed model as a general method for mapping complex traits in structured populations and applied to tomato. We detected a total of 44 loci that were significantly associated with a total of 19 traits, including sucrose, ascorbate, malate, and citrate levels. These results not only provide a list of candidate loci to be functionally validated but also a powerful analytical approach for finding genetic variants that can be directly used for crop improvement and deciphering the genetic architecture of complex traits.
Influence of electrosynthesis conditions and Al2O3 nanoparticles on corrosion protection effect of polypyrrole films
Authors: Ehsani Ali , Ghasem Mahjani Mohammad , Nasseri Maryam , Jafarian Majid 
Published: June 2014

Purpose
– The purpose of this paper was to investigate the anti-corrosion behavior of polypyrrole (PPy) films in different states and presence of alumina nanoparticles synthesized by galvanostatic electropolymerization on stainless steel (SS) electrodes in an artificial seawater solution using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS).

Design/methodology/approach
– The electrochemical measurements were used to examine the effects of PPy and its nanocomposite on the corrosion behavior of SS type 316L in artificial seawater. A standard electrochemical cell with three electrodes was used for the measurements. The electrochemical response of the coated electrodes in the doped and the undoped state was compared with that of a bare electrode. Corrosion rate information was obtained by the Tafel extrapolation method, where the intersection point of a cathodic and an anodic polarization curve provides both the corrosion potential and the corrosion current. EIS measurements confirmed the potentiodynamic and open circuit potential (OCP) results. The microstructure of the obtained films was investigated by scanning electron microscopy.

Findings
– The results showed that the coated polymer films shifted the electrode potential toward more positive potentials, but this shift did not lead to passivation. However, a notable synergy was observed between PPy undoped film, oxygen reduction and iron dissolution. The potential of the SS remained in the active dissolution region, and it was not possible to produce a passive oxide layer in this region. PPy separates the metal dissolution process from the oxygen reduction process. This would prevent the local pH increase at the metal surface and subsequent delamination. The polarization curves, EOCP and impedance measurements showed that PPy undoped/Al2O3 layers show promise as good candidates for the corrosion protection of reactive metals.

Originality/value
– This paper presents that electrodes coated with undoped PPy synthesized in the presence of dodecyl sulfate anions and Al2O3 nanoparticles offered a noticeable enhancement of protection against corrosion processes.
