OBJECTIVE
Spinal cord injury occurs in 2 phases. The initial trauma is followed by inflammation that leads to fibrous scar tissue, glial scarring, and cavity formation. Scarring causes further axon death around and above the injury. A reduction in secondary injury could lead to functional improvement. In this study, hyaluronic acid (HA) hydrogels were implanted into the gap formed in the hemisected spinal cord of Sprague-Dawley rats in an attempt to attenuate damage and regenerate tissue.

METHODS
A T-10 hemisection spinal cord injury was created in adult male Sprague-Dawley rats; the rats were assigned to a sham, control (phosphate-buffered saline), or HA hydrogel–treated group. One cohort of 23 animals was followed for 12 weeks and underwent weekly behavioral assessments. At 12 weeks, retrograde tracing was performed by injecting Fluoro-Gold in the left L-2 gray matter. At 14 weeks, the animals were killed. The volume of the lesion and the number of cells labeled from retrograde tracing were calculated. Animals in a separate cohort were killed at 8 or 16 weeks and perfused for immunohistochemical analysis and transmission electron microscopy. Samples were stained using H & E, neurofilament stain (neurons and axons), silver stain (disrupted axons), glial fibrillary acidic protein stain (astrocytes), and Iba1 stain (mononuclear cells).

RESULTS
The lesions were significantly smaller in size and there were more retrograde-labeled cells in the red nuclei of the HA hydrogel–treated rats than in those of the controls; however, the behavioral assessments revealed no differences between the groups. The immunohistochemical analyses revealed decreased fibrous scarring and increased retention of organized intact axonal tissue in the HA hydrogel–treated group. There was a decreased presence of inflammatory cells in the HA hydrogel–treated group. No axonal or neuronal regeneration was observed.

CONCLUSIONS
The results of these experiments show that HA hydrogel had a neuroprotective effect on the spinal cord by decreasing the magnitude of secondary injury after a lacerating spinal cord injury. Although regeneration and behavioral improvement were not observed, the reduction in disorganized scar tissue and the retention of neurons near and above the lesion are important for future regenerative efforts. In addition, this gel would be useful as the base substrate in the development of a more complex scaffold.

Abstract. In this paper, we studied the frequency of occurrence and shortwave direct radiative effects (DREs) of above-cloud aerosols (ACAs) over global oceans using 8 years (2007–2014) of collocated CALIOP and MODIS observations. Similar to previous work, we found high ACA occurrence in four regions: southeastern (SE) Atlantic region, where ACAs are mostly light-absorbing aerosols, i.e., smoke and polluted dust according to CALIOP classification, originating from biomass burning over the African Savanna; tropical northeastern (TNE) Atlantic and the Arabian Sea, where ACAs are predominantly windblown dust from the Sahara and Arabian deserts, respectively; and the northwestern (NW) Pacific, where ACAs are mostly transported smoke and polluted dusts from Asian. From radiative transfer simulations based on CALIOP–MODIS observations and a set of the preselected aerosol optical models, we found the DREs of ACAs at the top of atmosphere (TOA) to be positive (i.e., warming) in the SE Atlantic and NW Pacific regions, but negative (i.e., cooling) in the TNE Atlantic Ocean and the Arabian Sea. The cancellation of positive and negative regional DREs results in a global ocean annual mean diurnally averaged cloudy-sky DRE of 0.015 W m−2 (range of −0.03 to 0.06 W m−2) at TOA. The DREs at surface and within the atmosphere are −0.15 W m−2 (range of −0.09 to −0.21 W m−2), and 0.17 W m−2 (range of 0.11 to 0.24 W m−2), respectively. The regional and seasonal mean DREs are much stronger. For example, in the SE Atlantic region, the JJA (July–August) seasonal mean cloudy-sky DRE is about 0.7 W m−2 (range of 0.2 to 1.2 W m−2) at TOA. All our DRE computations are publicly available1. The uncertainty in our DRE computations is mainly caused by the uncertainties in the aerosol optical properties, in particular aerosol absorption, the uncertainties in the CALIOP operational aerosol optical thickness retrieval, and the ignorance of cloud and potential aerosol diurnal cycle. In situ and remotely sensed measurements of ACA from future field campaigns and satellite missions and improved lidar retrieval algorithm, in particular vertical feature masking, would help reduce the uncertainty. 1 https://drive.google.com/folderview?id=0B6gKx4dgNY0GMVYzcEd0bkZmRmc&amp;usp=sharing

Published: March 2016

AbstractPeroxisomes are dynamic organelles that play an essential role in a variety of metabolic pathways. Peroxisomal dysfunction can lead to various biochemical abnormalities and result in abnormal metabolite levels, such as increased very long‐chain fatty acid or reduced plasmalogen levels. The metabolite abnormalities in peroxisomal disorders are used in the diagnostics of these disorders. In this paper we discuss in detail the different diagnostic tests available for peroxisomal disorders and focus specifically on the important role of biochemical and functional studies in cultured skin fibroblasts in reaching the right diagnosis. Several examples are shown to underline the power of such studies.

Published: March 2016

Abstract

Background and aims
The symptoms of pain and depression often present concomitantly, but little is known as to how the different subtypes of depression affect surgical outcome. The aim of this study was to determine whether there is a difference in outcome after lumbar spine surgery between non-depressed patients and patients with different subtypes of depressive symptoms: non-melancholic (NmDS) and melancholic depression (MDS).

Methods
This was a cross-sectional postal survey. A self-made questionnaire, the Beck Depression Inventory (BDI) and the Oswestery Low Back Disability Questionnaire (ODI) were sent to patients who had undergone lumbar spine surgery in the Oulu University Hospital between June, 2005 and May, 2008. BDI ≤ 10 were further classified into NmDS or MDS.

Results
A total of 537 patients (66%) completed the survey. Of these, 361 (67%) underwent disc surgery, 85 (16%) stabilizing surgery and 91 (17%) decompression. Participants were divided into three groups: BDI< 10 N=324 (60%), NmDS N=153 (29%) and MDS N=60 (11%). The mean ODI (SD) in the BDI<1 0 group was 16 (15), in the NmDS group 36 (15), and in the MDS group 41 (18) (p<0.001). The ODI profiles were different between the groups (p<0.001). Pain was more frequent in depressive patients (88% of MDS, 81% in NmDS and 40% in BDI < 10 patients experienced pain, p<0.001). The intensity of pain and pain-related disability was lowest among the patients in the BDI <10 group and highest among the MDS patients. Regular pain medication was used by 87% of patients in the MDS group, 93% of patients in the NmDS group, and 71% of patients in the BDI< 10 group (p<0.001). Response to pain medication with NRS (0–10) was 5.6 among MDS, 5.8 among NmDS and 6.5 among BDI< 10 patients (p<0.001).

Conclusion
Different types of depressive symptoms are associated with poor outcome after lumbar spine surgery. The outcome was worst in patients suffering from the MDS subtype. This was observed in pain intensity, functional disability and response to pain medication.

Implication
It would be important to evaluate depression pre- and postoperatively. Offering a tailored rehabilitation programme to MDS patients should be considered.

Neuroimaging Findings and Repeat Neuroimaging Value in Pediatric Chronic Ataxia
Authors: Salman Michael S , Chodirker Bernard N , Bunge Martin 
Published: March 2016

AbstractBackground: Chronic ataxia, greater than two months in duration, is encountered relatively commonly in clinical pediatric neurology practise and presents with diagnostic challenges. It is caused by multiple and diverse disorders. Our aims were to describe the neuroimaging features and the value of repeat neuroimaging in pediatric chronic ataxia to ascertain their contribution to the diagnosis and management. Materials and Methods: A retrospective charts and neuroimaging reports review was undertaken in 177 children with chronic ataxia. Neuroimaging in 130 of 177 patients was also reviewed. Results: Nineteen patients had head computed tomography only, 103 brain magnetic resonance imaging only, and 55 had both. Abnormalities in the cerebellum or other brain regions were associated with ataxia. Neuroimaging was helpful in 73 patients with 30 disorders: It was diagnostic in 9 disorders, narrowed down the diagnostic possibilities in 14 disorders, and revealed important but non-diagnostic abnormalities, e.g. cerebellar atrophy in 7 disorders. Having a normal magnetic resonance imaging scan was mostly seen in genetic diseases or in the early course of ataxia telangiectasia. Repeat neuroimaging, performed in 108 patients, was generally helpful in monitoring disease evolution and in making a diagnosis. Neuroimaging was not directly helpful in 36 patients with 10 disorders or by definition the 55 patients with unknown disease etiology. Conclusions: Normal or abnormal neuroimaging findings and repeat neuroimaging are very valuable in the diagnosis and management of disorders associated with pediatric chronic ataxia.
ORDERING CESSATION OF COURT PROCEEDINGS TO PROTECT THE INTEGRITY OF ARBITRATION AGREEMENTS UNDER THE BRUSSELS I REGIME
Authors: Demirkol Berk 
Published: March 2016

AbstractThe CJEU judgment in West Tankers created much controversy on the question of whether issuing an anti-suit injunction in order to protect the integrity of arbitration agreements should fall within the scope of the arbitration exclusion in Article 1 of the Brussels I Regulation (2001). The negative answer of the Court has been since challenged many times by academics and practitioners and new approaches were proposed during the drafting of the Brussels I Recast. Although the Court had not since considered whether the Recast modified the legal regime, in Gazprom the Advocate General gave his opinion on the basis that it had. The Court in Gazprom, however, saw the enforcement of an arbitral award ordering cessation of court proceedings to be a distinct issue which is not covered by the Brussels I Regulation. This article discusses first the applicability of the Brussels I Regulation to the enforcement of arbitral awards ordering anti-suit injunction as a final relief. Secondly, it examines anti-suit injunctions issued by Member State courts in the post-Recast era. It aims to reveal the extent to which an order for cessation of court proceedings (or an anti-suit injunction) to protect the integrity of arbitration agreements is permissible under existing law.
Is urban bushmeat trade in Colombia really insignificant?

Published: March 2016

AbstractThe bushmeat trade in ecosystems in South America other than those within the Amazon basin is presumed to be insignificant, as alternative sources of protein (e.g. beef, chicken, fish) are considered to be more readily available in non-moist forests. However, studies and confiscation reports from countries such as Colombia suggest that bushmeat is consumed in a variety of ecosystems, although the nature of market chains, particularly in urban areas, is still unknown. We studied the urban bushmeat trade in markets in the five main ecoregions in Colombia. We recorded a total of 85 species, the most frequently traded being the pacaCuniculus paca, red brocket deerMazama americana, grey brocket deerMazama gouazoubira, capybaraHydrochoerus hydrochaeris, armadilloDasypusspp. and black agoutiDasyprocta fuliginosa. Most sales of wild meat occur through clandestine channels and involve a limited number of stakeholders. Bushmeat is a luxury product in urban areas of the Caribbean, the Pacific and the Andean regions. Further work is needed to quantify and monitor the volumes of bushmeat traded, comprehend motivations, explore ways of reducing threats, and engage with stakeholders to organize legal and sustainable use of bushmeat.
Evolution of affective and linguistic disambiguation under social eavesdropping pressures
Authors: Clark Kevin B. 
Published: March 2016

AbstractContradicting new dual-pathway models of language evolution, cortico-striatal-thalamic circuitry disambiguate uncertainties in affective prosody and propositional linguistic content of language production and comprehension, predictably setting limits on useful complexity of articulate phonic and/or signed speech. Such limits likely evolved to ensure public information is discriminated by intended communicants and safeguarded against the ecological pressures of social eavesdropping within and across phylogenetic boundaries.
Differences in auditory timing between human and nonhuman primates
Authors: Honing Henkjan , Merchant Hugo 
Published: March 2016

AbstractThe gradual audiomotor evolution hypothesis is proposed as an alternative interpretation to the auditory timing mechanisms discussed in Ackermann et al.'s article. This hypothesis accommodates the fact that the performance of nonhuman primates is comparable to humans in single-interval tasks (such as interval reproduction, categorization, and interception), but shows differences in multiple-interval tasks (such as entrainment, synchronization, and continuation).
Modification of spectral features by nonhuman primates

Published: March 2016

AbstractAckermann et al. discuss the lack of evidence for vocal control in nonhuman primates. We suggest that nonhuman primates may be capable of achieving greater vocal control than previously supposed. In support of this assertion, we discuss new evidence that nonhuman primates are capable of modifying spectral features in their vocalizations.

Published: March 2016

SUMMARYThe West African 2014 Ebola outbreak has highlighted the need for a better information network. Hybrid information networks, an integration of both hierarchical and formalized command control-driven and community-based, orad hocemerging networks, could assist in improving public health responses. By filling the missing gaps with social media use, the public health response could be more proactive rather than reactive in responding to such an outbreak of global concern. This article provides a review of the current social media use specifically in this outbreak by systematically collecting data from ProQuest Newsstand, Dow Jones Factiva, Program for Monitoring Emerging Diseases (ProMED) as well as Google Trends. The period studied is from 19 March 2014 (first request for information on ProMED) to 15 October 2014, a total of 31 weeks. The term ‘Ebola’ was used in the search for media reports. The outcome of the review shows positive results for social media use in effective surveillance response mechanisms – for improving the detection, preparedness and response of the outbreak – as a complement to traditional, filed, work-based surveillance approach.

SUMMARYIt is of great concern that pregnant women with acute viral hepatitis (AVH) type E have serious consequences. This study aimed to estimate the case-fatality risk (CFR) and potential risk factors of pregnant women with AVH type E. We searched the PubMed, EMBASE, and Web of Science databases for studies containing data on CFR in pregnancy with AVH type E. A pooled estimate of CFR was calculated using a random-effects model. Potential sources of heterogeneity were explored using subgroup analysis, sensitivity analysis, and meta-regression. We identified 47 eligible studies with a total African and Asian population of 3968 individuals. The pooled CFRs of maternal and fetal outcomes were 20·8% [95% confidence interval (CI) 16·6–25·3] and 34·2% (95% CI 26·0–43·0), respectively. Compared with these, the pooled CFR was highest (61·2%) in women with fulminant hepatic failure (FHF). Community-based surveys had lower pooled CFR (12·2%, 95% CI 9·2–15·6) and heterogeneity (25·8%, 95% CI 20·1–32·0) than hospital-based surveys. Univariate analysis showed that hospital-based surveying (P = 0·007), and patients in the third trimester of pregnancy or with FHF (P < 0·05), were significantly associated with CFR. Intrauterine fetal mortality (27·0%) was statistically higher than neonatal mortality (3·9%). Control measures for HEV infection would reduce feto-maternal mortality in Asia and Africa.
Seasonal determinations of algal virus decay rates reveal overwintering in a temperate freshwater pond
Authors: Long Andrew M , Short Steven M 
Published: March 2016

Abstract
To address questions about algal virus persistence (i.e., continued existence) in the environment, rates of decay of infectivity for two viruses that infect Chlorella-like algae, ATCV-1 and CVM-1, and a virus that infects the prymnesiophyte Chrysochromulina parva, CpV-BQ1, were estimated from in situ incubations in a temperate, seasonally frozen pond. A series of experiments were conducted to estimate rates of decay of infectivity in all four seasons with incubations lasting 21 days in spring, summer and autumn, and 126 days in winter. Decay rates observed across this study were relatively low compared with previous estimates obtained for other algal viruses, and ranged from 0.012 to 11% h−1. Overall, the virus CpV-BQ1 decayed most rapidly whereas ATCV-1 decayed most slowly, but for all viruses the highest decay rates were observed during the summer and the lowest were observed during the winter. Furthermore, the winter incubations revealed the ability of each virus to overwinter under ice as ATCV-1, CVM-1 and CpV-BQ1 retained up to 48%, 19% and 9% of their infectivity after 126 days, respectively. The observed resilience of algal viruses in a seasonally frozen freshwater pond provides a mechanism that can support the maintenance of viral seed banks in nature. However, the high rates of decay observed in the summer demonstrate that virus survival and therefore environmental persistence can be subject to seasonal bottlenecks.
Multi-year assessment of coastal planktonic fungi reveals environmental drivers of diversity and abundance
Authors: Taylor Joe D , Cunliffe Michael 
Published: March 2016

Abstract
Mycoplankton have so far been a neglected component of pelagic marine ecosystems, having been poorly studied relative to other plankton groups. Currently, there is a lack of understanding of how mycoplankton diversity changes through time, and the identity of controlling environmental drivers. Using Fungi-specific high-throughput sequencing and quantitative PCR analysis of plankton DNA samples collected over 6 years from the coastal biodiversity time series site Station L4 situated off Plymouth (UK), we have assessed changes in the temporal variability of mycoplankton diversity and abundance in relation to co-occurring environmental variables. Mycoplankton diversity at Station L4 was dominated by Ascomycota, Basidiomycota and Chytridiomycota, with several orders within these phyla frequently abundant and dominant in multiple years. Repeating interannual mycoplankton blooms were linked to potential controlling environmental drivers, including nitrogen availability and temperature. Specific relationships between mycoplankton and other plankton groups were also identified, with seasonal chytrid blooms matching diatom blooms in consecutive years. Mycoplankton α-diversity was greatest during periods of reduced salinity at Station L4, indicative of riverine input to the ecosystem. Mycoplankton abundance also increased during periods of reduced salinity, and when potential substrate availability was increased, including particulate organic matter. This study has identified possible controlling environmental drivers of mycoplankton diversity and abundance in a coastal sea ecosystem, and therefore sheds new light on the biology and ecology of an enigmatic marine plankton group. Mycoplankton have several potential functional roles, including saprotrophs and parasites, that should now be considered within the consensus view of pelagic ecosystem functioning and services.

Abstract
Phylogeny is an ecologically meaningful way to classify plants and animals, as closely related taxa frequently have similar ecological characteristics, functional traits and effects on ecosystem processes. For bacteria, however, phylogeny has been argued to be an unreliable indicator of an organism’s ecology owing to evolutionary processes more common to microbes such as gene loss and lateral gene transfer, as well as convergent evolution. Here we use advanced stable isotope probing with 13C and 18O to show that evolutionary history has ecological significance for in situ bacterial activity. Phylogenetic organization in the activity of bacteria sets the stage for characterizing the functional attributes of bacterial taxonomic groups. Connecting identity with function in this way will allow scientists to begin building a mechanistic understanding of how bacterial community composition regulates critical ecosystem functions.
