Meningoencephalocele, bilateral anorchia with radial and fibular hemimelia in a piglet
Authors: Abiola J. , Omotosho O. , Igado O. 
Published: September 2017

Abstract
Introduction: Birth defects still remain one of the major causes of economic wastage in livestock farming. It may be caused by a number of aetiologies. Meningoencephalocele results from neural tube defect during embryology. It is incompatible with life. Materials and methods: This is a case report of a stillbirth pig, which was presented with a swelling on the frontal part of the skull, and a number of other musculoskeletal defects. The affected piglet was farrowed with 5 other piglets by a 4 year old sow with previous uneventful farrowings. All other piglets in the litter showed no physical abnormalities post parturition. Results: Gross examination revealed meningocele with a circumference of 19 cm. Necropsy and x-ray (dorso-ventral view) revealed skeletal deformities which involved the long bones and the axial skeleton. The long bones were considerably shortened, with some having a 'twisted' appearance, while the vertebral column showed scoliosis. X-ray also revealed non-closure of the frontal bone of the skull, which resulted in herniation of brain material. Other abnormalities included bilateral anorchia, anophthalmos, cleft lip, atresia ani and multiple skeletal deformities. A rudimentary phallus was present, but dissection of abdominal and pelvic cavities revealed absence of any identifiable reproductive organs (male or female). Conclusion: Abnormalities observed were not compatible with life. This is probably the first electronically documented report of meningoencephalocele of the pig, with the reported accompanying multi organ and skeletal abnormalities in Nigeria.

Published: September 2017

Abstract. The perilipin gene (PLIN) plays a crucial role in lipid metabolism and fat deposition. In order to reveal the genetic effects of PLIN polymorphisms on body weight (BW) traits in chickens, PLIN gene polymorphisms in 322 Jinmao Hua chickens were detected by PCR-SSCP and DNA sequencing methods. For PLIN primer pair 1, five genotypes (AA, AB, BB, JJ and JL) were detected in the Jinmao Hua chicken population and three mutations (g.1889C > T, g.1904T > C and g.1922C > T) were revealed by gene sequencing. For PLIN primer pair 2, three genotypes (CC, CD and DD) were detected in the same population and two mutations (g.2014A > G and g.2020C > T) were revealed by gene sequencing. Least squares analysis showed that individuals with the JJ and CD genotypes performed better than the other Jinmao Hua chicken genotypes. Based on the five SNPs, the frequency distributions of the eight haplotypes were estimated with PHASE2.1 software. C-T-C-G-T was the major haplotype with a frequency of 58.6957 %, while the frequency of C-C-C-A-C was less than 1 %. Fourteen diplotypes were obtained from the eight haplotypes. H1H1 was the dominant diplotype with a frequency of 47.205 %. Least squares analysis indicated that BW with the H3H3 diplotype was the lowest, while the H2H2 diplotype was the highest, suggesting that selecting for the H3H3 diplotype improved the BW traits of Jinmao Hua chickens. The findings of this study should be useful to expand the theoretical basis of the role the PLIN in poultry molecular breeding of poultry.

Abstract. Indole is a heterocyclic compound emitted by various plant species under stressed conditions or during flowering events. The formation, optical properties, and chemical composition of secondary organic aerosol (SOA) formed by low-NOx photooxidation of indole were investigated. The SOA yield (1. 3 ± 0. 3) was estimated from measuring the particle mass concentration with a scanning mobility particle sizer (SMPS) and correcting it for wall loss effects. The high value of the SOA mass yield suggests that most oxidized indole products eventually end up in the particle phase. The SOA particles were collected on filters and analysed offline with UV–vis spectrophotometry to measure the mass absorption coefficient (MAC) of the bulk sample. The samples were visibly brown and had MAC values of  ∼ 2 m2 g−1 at λ = 300 nm and  ∼ 0. 5 m2 g−1 at λ = 400 nm, comparable to strongly absorbing brown carbon emitted from biomass burning. The chemical composition of SOA was examined with several mass spectrometry methods. Direct analysis in real-time mass spectrometry (DART-MS) and nanospray desorption electrospray high-resolution mass spectrometry (nano-DESI-HRMS) were both used to provide information about the overall distribution of SOA compounds. High-performance liquid chromatography, coupled to photodiode array spectrophotometry and high-resolution mass spectrometry (HPLC-PDA-HRMS), was used to identify chromophoric compounds that are responsible for the brown colour of SOA. Indole derivatives, such as tryptanthrin, indirubin, indigo dye, and indoxyl red, were found to contribute significantly to the visible absorption spectrum of indole SOA. The potential effect of indole SOA on air quality was explored with an airshed model, which found elevated concentrations of indole SOA during the afternoon hours contributing considerably to the total organic aerosol under selected scenarios. Because of its high MAC values, indole SOA can contribute to decreased visibility and poor air quality.
Bayesian calibration of terrestrial ecosystem models: a study of advanced Markov chain Monte Carlo methods

Published: September 2017

Abstract. Calibration of terrestrial ecosystem models is important but challenging. Bayesian inference implemented by Markov chain Monte Carlo (MCMC) sampling provides a comprehensive framework to estimate model parameters and associated uncertainties using their posterior distributions. The effectiveness and efficiency of the method strongly depend on the MCMC algorithm used. In this work, a differential evolution adaptive Metropolis (DREAM) algorithm is used to estimate posterior distributions of 21 parameters for the data assimilation linked ecosystem carbon (DALEC) model using 14 years of daily net ecosystem exchange data collected at the Harvard Forest Environmental Measurement Site eddy-flux tower. The calibration of DREAM results in a better model fit and predictive performance compared to the popular adaptive Metropolis (AM) scheme. Moreover, DREAM indicates that two parameters controlling autumn phenology have multiple modes in their posterior distributions while AM only identifies one mode. The application suggests that DREAM is very suitable to calibrate complex terrestrial ecosystem models, where the uncertain parameter size is usually large and existence of local optima is always a concern. In addition, this effort justifies the assumptions of the error model used in Bayesian calibration according to the residual analysis. The result indicates that a heteroscedastic, correlated, Gaussian error model is appropriate for the problem, and the consequent constructed likelihood function can alleviate the underestimation of parameter uncertainty that is usually caused by using uncorrelated error models.

Published: September 2017

Abstract. We assessed sediment coring, data acquisition, and publications from the North Pacific (north of 30° N) from 1951 to 2016. There are 2134 sediment cores collected by American, French, Japanese, Russian, and international research vessels across the North Pacific (including the Pacific subarctic gyre, Alaskan gyre, Japan margin, and California margin; 1391 cores), the Sea of Okhotsk (271 cores), the Bering Sea (123 cores), and the Sea of Japan (349 cores) reported here. All existing metadata associated with these sediment cores are documented here, including coring date, location, core number, cruise number, water depth, vessel metadata, and coring technology. North Pacific sediment core age models are built with isotope stratigraphy, radiocarbon dating, magnetostratigraphy, biostratigraphy, tephrochronology, % opal, color, and lithological proxies. Here, we evaluate the iterative generation of each published age model and provide comprehensive documentation of the dating techniques used, along with sedimentation rates and age ranges. We categorized cores according to the availability of a variety of proxy evidence, including biological (e.g., benthic and planktonic foraminifera assemblages), geochemical (e.g., major trace element concentrations), isotopic (e.g., bulk sediment nitrogen, oxygen, and carbon isotopes), and stratigraphic (e.g., preserved laminations) proxies. This database is a unique resource to the paleoceanographic and paleoclimate communities and provides cohesive accessibility to sedimentary sequences, age model development, and proxies. The data set is publicly available through PANGAEA at https://doi.org/10.1594/PANGAEA.875998.
Information content of stream level class data for hydrological model calibration
Authors: van Meerveld H. J. Ilja , Vis Marc J. P. , Seibert Jan 
Published: September 2017

Abstract. Citizen science can provide spatially distributed data over large areas, including hydrological data. Stream levels are easier to measure than streamflow and are likely also observed more easily by citizen scientists than streamflow. However, the challenge with crowd based stream level data is that observations are taken at irregular time intervals and with a limited vertical resolution. The latter is especially the case at sites where no staff gauge is available and relative stream levels are observed based on (in)visible features in the stream, such as rocks. In order to assess the potential value of crowd based stream level observations for model calibration, we pretended that stream level observations were available at a limited vertical resolution by transferring streamflow data to stream level classes. A bucket-type hydrological model was calibrated with these hypothetical stream level class data and subsequently evaluated on the observed streamflow records. Our results indicate that stream level data can result in good streamflow simulations, even with a reduced vertical resolution of the observations. Time series of only two stream level classes, e.g. above or below a rock in the stream, were already informative, especially when the class boundary was chosen towards the highest stream levels. There was some added value in using up to five stream level classes, but there was hardly any improvement in model performance when using more level classes. These results are encouraging for citizen science projects and provide a basis for designing observation systems that collect data that are as informative as possible for deriving model based streamflow time series for previously ungauged basins.
Pseudoaneurysm
Authors: Peters Sophie , Braun-Dullaeus Ruediger , Herold Joerg 
Published: September 2017

SummaryPseudoaneurysms (PSAs) are commonly known as complications associated with invasive interventions. Because of the pulsatile in- and outflow of blood through the neck of PSAs, they tend to grow and, in the worse cases, can rupture. Therapeutic options are compression therapy, using a compression bandage and ultrasound-guided compression, and thrombin injection. Manual ultrasound-guided compression is widely performed and is successful in most cases. In general, it is combined with a subsequently applied compression bandage. Thrombin injection is a more difficult technique, but it has a higher success rate. This article gives an overview of the characteristics of PSAs, their diagnostic characteristics and the therapeutic methods used to treat them. Complications associated with compression or thrombin injection are also explained in detail.

Abstract
Arabitol is a polyalcohol which has about 70% of the sweetness of sucrose and an energy density of 0.2 kcal/g. Similarly to xylitol, it can be used in the food and pharmaceutical industries as a natural sweetener, a texturing agent, a dental caries reducer, and a humectant. Biotechnological production of arabitol from sugars represents an interesting alternative to chemical production. The yeast Scheffersomyces shehatae strain 20BM-3 isolated from rotten wood was screened for its ability to produce arabitol from L-arabinose, glucose, and xylose. This isolate, cultured at 28°C and 150 rpm, secreted 4.03 ± 0.00 to 7.97 ± 0.67 g/l of arabitol from 17–30 g/l of L-arabinose assimilated from a medium containing 20–80 g/l of this pentose with yields of 0.24 ± 0.00 to 0.36 ± 0.02 g/g. An optimization study demonstrated that pH 4.0, 32°C, and a shaking frequency of 150 rpm were the optimum conditions for arabitol production by the investigated strain. Under these conditions, strain 20BM-3 produced 6.2 ± 0.17 g/l of arabitol from 17.5 g/l of arabinose after 4 days with a yield of 0.35 ± 0.01 g/g. This strain also produced arabitol from glucose, giving much lower yields, but did not produce it from xylose. The new strain can be successfully used for arabitol production from abundantly available sugars found in plant biomass.

Abstract
The aim of the studies was to compare the composition of soil bacterial metabiomes originating from urbanized areas and areas contaminated with hydrocarbons with those from agricultural soil and forest soil obtained from a protected wild-life park area. It should be noted that hydrocarbons are everywhere therefore bacteria capable of their utilization are present in every soil type. In the hydrocarbon- contaminated soil and in the soil of anthropogenic origin, the bacteria belonging to Gammaproteobacteria were dominant (28.4–36.6%), whereas in the case of agricultural soil and protected wild-life park soil their ratios decreased (22.8–23.0%) and were similar to that of Alphaproteobacteria. No statistically significant changes were observed in terms of the Operational Taxonomic Unit identified in the studies soils, however, based on the determined alpha-diversity it can be established that contaminated soils were characterized by lower biodiversity indices compared to agricultural and forest soils. Furthermore, the dioxygenase level was also evaluated in the studied soils, which are genes encoding crucial enzymes for the decomposition of mono- and polycyclic aromatic hydrocarbons during the biodegradation of diesel oil (PAHRHDαGN, PAHRHDαGP, xylE, Cat 2,3, ndoB). It was concluded that both the population structure of the soil metabiome and the number of genes crucial for biodegradation processes differed significantly between the soils. The level of analysed genes showed a similar trend, as their highest number in relations to genes encoding 16S RNA was determined in urban and hydrocarbon-contaminated soil.

Abstract
Halophyte microbiome contributes significantly to plant performance and can provide information regarding complex ecological processes involved in osmoregulation of these plants. The objective of this study is to investigate the microbiomes associated with belowground (rhizosphere), internal (endosphere) and aboveground (phyllosphere) tissues of halophyte (Salsola stocksii) through metagenomics approach. Plant samples were collected from Khewra Salt Mines. The metagenomic DNA from soil, root and shoot samples was isolated with the help of FastDNA spin kit. Through PCR, the 16S rRNA gene from four different Salsola plants and wheat plants was amplified and cloned in InsTAclone PCR cloning kit. Metagenomic analyses from rhizosphere, endosphere and phyllosphere of Salsola showed that approximately 29% bacteria were uncultured and unclassified. Proteobacteria and Actinobacteria were the most abundant phyla in Salsola and wheat. However, Firmicutes, Acidobacteria, Bacteriodetes, Planctomycetes, Cyanobacteria, Thermotogae, Verrucomicrobia, Choroflexi and Euryarchaeota were predominant groups from halophyte whereas Actinobacteria, Proteobacteria, Firmicutes, Cyanobacteria, Acidobacteria, Bacteriodetes, Planctomycetes and Verrucomicrobia were predominant phyla of wheat samples. Diversity and differences of microbial flora of Salsola and wheat suggested that functional interactions between plants and microorganisms contribute to salt stress tolerance.
Genes Controlling 2-deoxyglucose Induced Lysis and Formation of Reactive Oxygen Species in Schizosaccharomyces pombe
Authors: VISHWANATHA AKSHAY , D’SOUZA CLETUS J.M. , SCHWEINGRUBER MARTIN E. 
Published: September 2017

Abstract

Schizosaccharomyces pombe cells of strains each carrying a deletion of one of the genes snf5, ypa1, pho7 and pas1 and of a strain overexpressing gene odr1, have been previously shown to grow in presence of the toxic glucose analogue 2-deoxyglucose (2-DG). Here we report that these genes control 2-DG induced lysis and are, with the exception of odr1, also involved in control of formation of reactive oxygen species (ROS) upon exposure of cells to H2O2. Lysis of deletion strains, but not of strain overexpressing odr1, is dependent on glucose concentration of the medium whereas ROS formation is glucose independent.

Abstract
From 123 clinical and environmental Pseudomonas aeruginosa isolates, 24 strains were selected for their similar antibioresistance, virulence and biofilm formation profiles, to examine their diversity and occurrence of clones within two hospitals and different natural sites in Meknes (Morocco). Pulsed-field gel electrophoresis, using DraI enzyme, didn’t reveal a close relationship between clinical and environmental isolates nor between strains of the two hospitals. 19 genotypes were obtained, including two virulent environmental clones and three clinical clones virulent and resistant to antibiotics. Intra-hospital transmission of high-risk clones detected, in and between wards, constitutes a great public health concern.

Abstract
Four Klebsiella pneumoniae isolates from children hospitalized over 10 months in an intensive care unit in a children’s teaching hospital in Poland were analyzed. All of the isolates belonged to a single pulsotype and sequence type (ST) 11, and produced the KPC-2 carbapenemase and extended-spectrum β-lactamase (ESBL) CTX-M-15. They were resistant to a variety of antimicrobials, and their β-lactam resistance patterns were typical for KPC producers. This is one of few cases of identification of KPC (or carbapenemase)-producing K. pneumoniae in a pediatric center in Poland.

Abstract
The objective of the present study was to describe the molecular characteristics of enteroviruses associated with hand, food, and mouth disease (HFMD) in Poland. Clinical material from HFMD cases, that occurred during 2013–2016 were examined. It has been showed that coxsackievirus A6 (CVA6), CVA10 and CVA16 were circulating in the country. Phylogenetic analysis showed that Polish CVA6 strains were divided into two distinct clusters suggesting two independent introductions. This is the first report of CVA6 infections associated with HFMD in Poland. These results emphasize the need for continuous monitoring of HFMD and facilitation of the diagnosis using molecular approaches.
Integração Produtiva Regional: a importância dos acordos preferenciais para a fragmentação produtiva
Authors: De Souza Karla Sarmento Gonçalves , Castilho Marta dos Reis 
Published: September 2017

Nas últimas décadas temos observado um aumento significativo dos fluxos comerciais globais, especialmente de partes e componentes, além de um aumento significativo no volume de investimento direto. A literatura econômica – teórica e empírica - tem apontado a relação desses fenômenos com o processo de fragmentação do processo produtivo. Mas, apesar de amplamente praticado, o conceito ainda não é bem definido na literatura. Neste artigo optou-se por agregá-los em dois grupos, os que tratam da fragmentação produtiva, ou seja, a divisão geográfica da produção, e a integração produtiva regional, que diz respeito a economias envolvidas em acordos preferenciais de comércio. Ademais, foram apontados os principais determinantes e os efeitos sobre o crescimento e desenvolvimento dos países envolvidos. E, para contextualizar o tema, foram brevemente apresentados os históricos de integração produtiva na América Latina e na Ásia. O levantamento bibliográfico realizado leva a conclusão que, apesar de distintos, os conceitos convergem na medida em que os acordos preferenciais são capazes de reduzir os custos de comercialização.
