Urban-rural mental health differences in Great Britain: findings from the National Morbidity Survey

Studies of urban-rural differences in prevalence of non-psychotic mental disorder have not given consistent findings. Such differences have received relatively little study in Great Britain. Data from 9777 subjects in the Household Survey of the National Morbidity Survey of Great Britain were analysed for differences between urban, semi-rural, and rural areas. Psychiatric morbidity was assessed by scores on the Revised Clinical Interview Schedule (CIS-R), together with alcohol dependence, drug dependence, and receipt of treatment from general practitioners. Associations with other characteristics were examined by logistic regression. Urban subjects had higher rates than rural of CIS-R morbidity, alcohol dependence, and drug dependence, with semi-rural subjects intermediate. Urban subjects also tended to be members of more deprived social groups, with more adverse living circumstances and greater life stress--factors themselves associated with disorder. Urban-rural differences in alcohol and drug dependence were no longer significant after adjustment for these factors by logistic regression, and differences on CIS-R morbidity were considerably reduced. There were no differences in treatment. There are considerable British urban-rural differences in mental health, which may largely be attributable to more adverse urban social environments.
Bone Turnover Markers as a New Predicting Factor for Nonunion After Spinal Fusion Surgery

Study Design. Retrospective observational study. Objective. We investigated whether bone turnover markers could be a useful indicator for prediction of nonunion. Summary of Background Data. Nonunion is a major complication of lumbar spinal fusion surgery. The involvement of bone turnover in the process of bony union in spinal fusion surgery is, however, poorly understood. Methods. Of the 74 patients analyzed, 13 were diagnosed with nonunion. We evaluated the significance of the following risk factors: age, sex, number of fused segments, serum levels of total alkaline phosphatase, procollagen type 1 amino-terminal propeptide (P1NP), tartrate-resistant acid phosphatase 5b (TRACP-5b), and albumin, and history of diabetes mellitus, cigarette smoking, or alcohol use. We also defined the bone turnover ratio (BTR) as a value that equals serum TRACP-5b concentration divided by serum P1NP concentration to evaluate patients’ individual bone turnover balance and investigated the significance of BTR as a risk factor. Results. Univariate analysis showed that older age, malnutrition, and lower P1NP are risk factors for nonunion. Stepwise logistic regression analysis revealed that in the presence of lower P1NP, higher TRACP-5b becomes a risk factor. Furthermore, we identified BTR as the most significant risk factor for nonunion. The optimum cut-off value of BTR by receiver-operating characteristic curve was 11.74. Conclusion. These findings show a relation between bone turnover and nonunion after spinal fusion surgery. The measurement of bone turnover markers could potentially be used to predict nonunion after spinal fusion surgery. Level of Evidence: 4
Human Cytomegalovirus pUS27 G Protein-Coupled Receptor Homologue Is Required for Efficient Spread by the Extracellular Route but Not for Direct Cell-to-Cell Spread

ABSTRACT Human cytomegalovirus (HCMV) encodes multiple G protein-coupled receptor (GPCR) homologues, including pUS27, pUS28, pUL33, and pUL78. To explore the function of pUS27, we constructed pUS27-deficient derivates of two clinical isolates of HCMV. BFX-GFPstopUS27 is a FIX variant with a single base pair change in the US27 open reading frame, generating a stop codon that ablates accumulation of the GPCR homologue, and TB40/E-mCherrydlUS27 lacks the entire US27 coding region. BFX-GFPstopUS27 generated 10-fold less extracellular progeny in fibroblasts, and TB40/E-mCherrydlUS27 exhibited a similar defect in endothelial cells. The pUS27-deficient FIX derivative produced normal quantities of viral DNA and viral proteins tested, and a late virion protein was appropriately localized to the cytoplasmic assembly zone. After infection at a low multiplicity with wild-type FIX virus, neutralizing antibody reduced the accumulation of intracellular viral DNA and intracellular virions, as would be expected if the virus is limited to direct cell-to-cell spread by neutralization of extracellular virus. In contrast, the antibody had little effect on the spread of the BFX-GFPstopUS27 virus. Further, after infection at a low multiplicity, the pUS27-deficient TB40/E virus exhibited a growth defect in endothelial cells, where the clinical isolate normally generates extracellular virus, but the TB40/E derivative exhibited little defect in epithelial cells, where the wild-type virus does not produce extracellular virus. Thus, mutants lacking pUS27 rely primarily on direct cell-to-cell spread, and we conclude that the viral GCPR homologue acts at a late stage of the HCMV replication cycle to support spread of virus by the extracellular route.
Deoxycholic Acid Induces Intracellular Signaling through Membrane Perturbations*

Secondary bile acids have long been postulated to be tumor promoters in the colon; however, their mechanism of action remains unclear. In this study, we examined the actions of bile acids at the cell membrane and found that they can perturb membrane structure by alteration of membrane microdomains. Depletion of membrane cholesterol by treating with methyl-β-cyclodextrin suppressed deoxycholic acid (DCA)-induced apoptosis, and staining for cholesterol with filipin showed that DCA caused a marked rearrangement of this lipid in the membrane. Likewise, DCA was found to affect membrane distribution of caveolin-1, a marker protein that is enriched in caveolae membrane microdomains. Additionally, fluorescence anisotropy revealed that DCA causes a decrease in membrane fluidity consistent with the increase in membrane cholesterol content observed after 4 h of DCA treatment of HCT116 cells. Significantly, by using radiolabeled bile acids, we found that bile acids are able to interact with and localize to microdomains differently depending on their physicochemical properties. DCA was also found to induce tyrosine phosphorylation and activate the receptor tyrosine kinase epidermal growth factor receptor in a ligand-independent manner. In contrast, ursodeoxycholic acid did not exhibit any of these effects even though it interacted significantly with the microdomains. Collectively, these data suggest that bile acid-induced signaling is initiated through alterations of the plasma membrane structure and the redistribution of cholesterol.
Differential fMRI Responses in the Left Posterior Superior Temporal Gyrus and Left Supramarginal Gyrus to Habituation and Change Detection in Syllables and Tones

Using a habituation-recovery paradigm adapted to functional magnetic resonance imaging, we investigated the brain responses to syllables and tones in six right-handed male subjects. We opposed a standard condition (STD) in which the subjects were listening to homogeneous sequences of four identical stimuli, to a deviant condition (DEV) in which the fourth stimulus of the sequence differed in pitch or spectral content for tones and in the initial stop consonant for syllables. The corresponding runs alternated four rest periods with two STD and two DEV conditions. In addition to a marked rightward asymmetry in the primary and secondary auditory cortex for tones and a right inferior frontal activation for the tone condition where the deviant had increased spectral content, the experiment revealed differential activations in the left posterior superior temporal gyrus and in the left supramarginal gyrus. Activations within the left posterior superior temporal gyrus were observed for the DEV condition with tones and for the STD and DEV conditions with syllables. Activation within the inferior part of the left supramarginal gyrus was only observed for the DEV condition with syllables. The analysis of the decreases and increases in the BOLD signal across the STD, DEV, and rest conditions suggests that the left posterior superior temporal gyrus is implicated in the preattentive change detection of acoustic changes in speech as well as nonspeech stimuli, whereas the left supramarginal gyrus is more specifically engaged in the detection of changes in phonological units.
Vascular parkinsonism: a distinct, heterogeneous clinical entity

Objectives– The aim of this study was to define the symptoms and signs of suspected vascular parkinsonism (VP) which is still a debatable concept. Material and methods– Patients with parkinsonism were grouped into patients with suspected VP and Parkinson's disease (PD) after other causes for secondary parkinsonism, and parkinsonism‐plus syndromes were excluded. The clinical features of 16 patients with suspected VP to those of 50 diagnosed with PD were compared. All patients were assessed using unified Parkinson's disease rating scale (UPDRS) and all had cerebral MRIs. Results– Patients with VP had significantly older onset age and shorter duration of disease with gait disorder as the most frequent initial symptom. All PD patients had satisfactory response to levodopa treatment, whereas only 38% VP patients had satisfactory response to levodopa treatment. Vascular risk factors were more common in VP (81%) than PD (32%). Postural instability, freezing, gait disturbance, pyramidal signs, and postural tremor were significantly more prevalent in patients with VP than in PD. In VP patients these features were more prominent in the lower limbs. Twenty‐five percent had acute onset VP. All patients with VP had ischemic lesions, mainly in subcortical white matter, to a lesser extent basal ganglia and brainstem, in their cerebral MRIs, while 70% of PD patients had normal MRIs. Conclusion– The differences in the clinical features support the concept that VP is a distinct clinical entity with heterogeneous clinical, MRI, and possibly pathophysiological features.
Feedback Trading: Strategies during Day and Night with Global Interconnectedness

Feedback trading strategies have gained much popularity among researchers in the last decades and are used to illustrate how new information based on returns is reflected in the markets. This paper extends previous studies by decomposing the overall return premium and introducing the global feedback trading model. The global feedback trading model assumes an interconnectedness between multiple countries and captures spillovers. Empirical results illustrate two important findings. First, feedback trading strategies differ across markets when distinguishing between day and night returns. Second, evidence for changing feedback trading is provided by examining the interaction of specific markets.
Three-dimensional interstitial space mediates predator foraging success in different spatial arrangements.

Identifying and quantifying the relevant properties of habitat structure that mediate predator-prey interactions remains a persistent challenge. Most previous studies investigate effects of structural density on trophic interactions and typically quantify refuge quality using one or two-dimensional metrics. Few consider spatial arrangement of components (i.e., orientation and shape) and often neglect to measure the total three-dimensional (3D) space available as refuge. This study tests whether the three-dimensionality of interstitial space, an attribute produced by the spatial arrangement of oyster (Crassostrea virginica) shells, impacts the foraging success of nektonic predators (primary blue crab, Callinectes sapidus) on mud crab prey (Eurypanopeus depressus) in field and mesocosm experiments. Interstices of 3D-printed shell mimics were manipulated by changing either their orientation (angle) or internal shape (crevice or channel). In both field and mesocosm experiments, under conditions of constant structural density, predator foraging success was influenced by 3D aspects of interstitial space. Proportional survivorship of tethered mud crabs differed significantly as 3D interstitial space varied by orientation, displaying decreasing prey survivorship as angle of orientation increased (0° = 0.76, 22.5° = 0.13, 45° = 0.0). Tethered prey survivorship was high when 3D interstitial space of mimics was modified by internal shape (crevice survivorship = 0.89, channel survivorship = 0.96) and these values did not differ significantly. In mesocosms, foraging success of blue crabs varied with 3D interstitial space as mean proportional survivorship (± SE) of mud crabs was significantly lower in 45° (0.27 ± 0.06) vs. 0° (0.86 ± 0.04) orientations and for crevice (0.52 ± 0.11) vs. channel shapes (0.95 ± 0.02). These results suggest that 3D aspects of interstitial space, which have direct relevance to refuge quality, can strongly influence foraging success in our oyster reef habitat. Our findings highlight the importance of spatial arrangement in mediating consumptive pathways in hard-structured habitats and demonstrate how quantifying the three-dimensionality of living space captures aspects of habitat structure that have been missing from previous empirical studies of trophic interactions and structural complexity.
Predictors of neonatal outcomes amongst a methadone‐ and/or heroin‐dependent population referred to a multidisciplinary Perinatal and Family Drug Health Service

Although methadone maintenance therapy is the standard of care for opioid‐dependent pregnant women, there exists controversy over the benefits and side effects of treatment to the neonate. Our aim was to document predictors of neonatal outcomes within an opioid‐using population, with particular reference to methadone treatment in the context of continued heroin use.
Geriatric rehabilitation of lower limb amputees: a multicenter study

Purpose: The aim of this study was to determine factors independently associated with successful rehabilitation of patients with lower limb amputation in skilled nursing facilities (SNFs). Methods: All patients admitted to one of the 11 participating SNFs were eligible. Multidisciplinary teams collected the data. Successful rehabilitation was defined as discharge to an independent living situation within 1 year after admission. Functional status at discharge, as measured with the Barthel index (BI), was a secondary outcome. Multivariate regression analyses were used to assess the independent contribution of each determinant to the two outcome measures. Results: Of 55 eligible patients, 48 were included. Mean age was 75 years. Sixty-five percent rehabilitated successfully. Multivariate analyses showed that presence of diabetes mellitus (DM) (OR 23.87, CI 2.26–252.47) and premorbid BI (OR 1.37, CI 1.10-1.70) were the most important determinants of successful rehabilitation, whereas 78% of the variance of discharge BI was explained by premorbid BI, BI on admission, and 1-leg balance. Conclusion: The presence of DM and high premorbid BI were associated with discharge to an independent living situation within 1 year after admission. Premorbid BI, admission BI, and 1-leg balance were independently associated to discharge BI. Implications for Rehabilitation Geriatric patients with amputation in SNFs have a fair prognosis of being discharged to an independent living situation after rehabilitation. Pre-operative functional abilities of geriatric amputees are important in predicting rehabilitation outcome. Improving physical condition before amputation could lead to better rehabilitation outcome.
A cell-specific enhancer of the mouse alpha 1-antitrypsin gene has multiple functional regions and corresponding protein-binding sites

We have previously described the isolation and characterization of genomic clones corresponding to the mouse alpha 1-antitrypsin gene (Krauter et al., DNA 5:29-36, 1986). In this report, we have analyzed the DNA sequences upstream of the RNA start site that direct hepatoma cell-specific expression of this gene when incorporated into recombinant plasmids. The 160 nucleotides 5' to the cap site direct low-level expression in hepatoma cells, and sequences between -520 and -160 bp upstream of the RNA start site functioned as a cell-specific enhancer of expression both with the alpha 1-antitrypsin promoter and when combined with a functional beta-globin promoter. Within the enhancer region, three binding sites for proteins present in hepatoma nuclear extracts were identified. The location of each site was positioned, using both methylation protection and methylation interference experiments. Each protein-binding site correlated with a functionally important region necessary for full enhancer activity. These experiments demonstrated a complex arrangement of regulatory elements comprising the alpha 1-antitrypsin enhancer. Significant qualitative differences exist between the findings presented here and the cis-acting elements operative in regulating expression of the human alpha 1-antitrypsin gene (Ciliberto et al., Cell 41:531-540, 1985; De Simone et al., EMBO J. 6:2759-2766, 1987).
The determinants of leverage decisions: Evidence from Asian emerging markets

Abstract This study provides a stage-level analysis of firm-scale pooled data of 16 Asian countries to classified income economy-based data for various firm- and country-specific predictors of leverage. Our analysis captures the selection impact of both micro- and macro-level determinants on capital structure with and without income economy-based models. The regression model evaluated the significance of predictor variables based on random effect model of panel data setting. The study further explores the issue of interest by looking at key individual regression models by income economy to avoid any potential loss of information. We argue that this approach provides a comprehensive and insightful set of determinants because of the newer dimension of income economy classification based on per-capita Gross National Product (GNP) defined by the World Bank. The estimating equations for financing determinants identify the additional variables of non-debt tax shield, liquidity, tax and GDP growth rate in case of Asian countries. Our study establishes that the core variables of tangibility, growth, size, and profitability retain their significance for leverage choice in both options during 2008–2014 in Asian economies. Furthermore, the findings show that the financing choices of firms in Asian regional markets are complemented by financial system development stages using the equity market, the bond market and the banking industry as proies.
Synaptic contacts of vesicular glutamate transporter 2 fibres on chemically identified neurons of the hypothalamic suprachiasmatic nucleus of the rat

The hypothalamic suprachiasmatic nucleus (SCN), which plays a pivotal role in the control of circadian rhythms, consists of several neuronal subpopulations characterized by different neuroactive substances. This prominent cell group has a fairly rich glutamatergic innervation, but the cell types that are targeted by this innervation are unknown. Therefore, the purpose of the present study was to examine the relationship between the afferent glutamatergic axon terminals and the vasoactive intestinal polypeptide (VIP)‐, arginine‐vasopressin (AVP)‐ and γ‐aminobutyric acid (GABA)‐positive neurons of the SCN. Glutamatergic elements were revealed via immunocytochemical double‐labelling for vesicular glutamate transporter type 1 (VGluT1) and type 2 (VGluT2), and brain sections were imaged via confocal laser‐scanning microscopy and electron microscopy. Numerous VGluT2‐immunoreactive axons were observed to be in synaptic contact with VIP‐ and GABA‐positive neurons, and only a few synapses were detected between VGluT2 boutons and AVP neurons. VGluT1 axon terminals exhibiting very moderate distribution in this cell group were observed to be in synaptic contact with chemically unidentified neurons. The findings provide the first morphological data on the termination of presumed glutamatergic fibres on chemically identified neurons of the rat SCN, and indicate that all three prominent cell types of the cell group receive glutamatergic afferents.
Solving Multi-controller Placement Problem in Software Defined Network

The Software Defined Network (SDN), is the next generation Internet technology, which not only solve the ossification of the Internet, but also creates new innovations and simplify the network management. The key idea behind SDN is separation of control plane from data plane, as a result devices in the data plane becomes the forwarding device and transfer all the decision making activities in a centralized system called a controller. In SDN architecture, it is a great challenge to find a solution to the controller placement problem (CPP). The CPP decides where to place the K number of controllers with a limited amount of resources within the SDN network. Among many proposed solutions to this problem, we apply clustering algorithms such as K-median, K-center on the topology which are obtained from a topology-zoo. A spectral clustering technique has been proposed for partitioning the network and place the controller within the sub-domain. Latency is one of the performance matrices that we have considered in the simulation. The simulation results show that the graph partition method reduces the inter-controller latency within the network.
Pakchoi Antioxidant Improvement and Differential Rhizobacterial Community Composition under Organic Fertilization

A high level of antioxidants in organic-produced vegetables has been attributed to soil conditions; however, little is known about the relationships between antioxidants and rhizobacteria under different fertilization treatments. A pot trial for pakchoi (Brassica campestris ssp. chinensis L.) was conducted under greenhouse conditions with: (1) control; (2) chemical fertilizer; and (3) organic fertilizer. The responses of the plant, soil properties, and rhizobacterial community were measured after 45 days of cultivation. Fertilization increased soil nutrient levels and pakchoi productivity and the reshaped rhizobacterial community structure, while no differences in rhizobacterial abundance and total diversity were observed. Generally, most plant antioxidants were negatively correlated with inorganic nitrogen (N) and positively correlated to organic N in soil. The genera of Arthrospira and Acutodesmus contained differential rhizobacteria under chemical fertilizer treatment, which are known as copiotrophs. In addition, the addition of a chemical fertilizer may stimulate organic substance turnover by the enrichment of organic compound degraders (e.g., Microbacterium and Chitinophaga) and the promotion of predicted functional pathways involved in energy metabolism. Several beneficial rhizobacteria were associated with organic fertilizer amended rhizosphere including the genera Bacillus, Mycobacterium, Actinomycetospora, and Frankia. Furthermore, Bacillus spp. were positively correlated with plant biomass and phenolic acid. Moreover, predictive functional profiles of the rhizobacterial community involved in amino acid metabolism and lipid metabolism were significantly increased under organic fertilization, which were positively correlated with plant antioxidant activity. Overall, our study suggests that the short-term application of chemical and organic fertilizers reshapes the rhizobacterial community structure, and such changes might contribute to the plant’s performance.
