First Record of Anopheles darlingi Root (Diptera, Culicidae) in the Volta Grande Environmental Reserve, Conceição das Alagoas Municipality, Minas Gerais, Brazil
Authors: Martins Rafael , Monteiro Graziella França , Costa Fábio Medeiros da , Antonini Yasmine 
Published: April 2015

Three specimens of Anopheles darlingi Root were found in the Volta Grande environmental reserve, an area influenced by the Rio Grande dam constructed by the Volta Grande hydroelectric plant in Conceição das Alagoas, Minas Gerais, Brazil. The mosquito An. darlingi is one of the main vectors of human malaria in Brazil due to feeding preference for human blood, a factor that is accentuated by endophilic behavior. The information recorded here may be helpful to local entomological surveillance toward monitoring impacts generated by hydroelectric reservoir formation, as the presence of this vector in this type of environment indicates a potential risk for malaria transmission.

Published: April 2015

Vision screening is an important function of the school nurse's role. Parental cooperation after a child's failed vision screening remains a problematic issue for school nurses, as research reveals inconsistent follow-up and a low rate of parental adherence to school nursing screening referral. Using a comparative descriptive design, the purpose of this investigation was to determine if there was an improvement in parental adherence after a failed vision screening referral in school-age children in an urban middle school setting when implementing an approach consisting of a comprehensive informative letter and telephone follow-up versus the use of a standard referral card commonly used in practice. Findings revealed a statistically significant increase in the number of school-age children who received professional eye care services with the use of the informative letter and telephone follow-up calls (P<0.001), as well as an increase in the number of eye care appointments made (P<0.001). Numerous barriers to care were identified. The use of an informative letter and follow-up telephone communication was effective in improving parental adherence to vision screening referral and demonstrates the essential role that school nurses have in promoting child health.

Abstract

BACKGROUND
Recent progress in the analysis of cell-free DNA fragments [cell-free circulating tumor DNA (ctDNA)] now allows monitoring of tumor genomes by noninvasive means. However, previous studies with plasma DNA from patients with cancer demonstrated highly variable allele frequencies of ctDNA. The comprehensive analysis of tumor genomes is greatly facilitated when plasma DNA has increased amounts of ctDNA. Therefore, a fast and cost-effective prescreening method to identify such plasma samples without previous knowledge about alterations in the respective tumor genome could assist in the selection of samples suitable for further extensive qualitative analysis.

METHODS
We adapted the recently described Fast Aneuploidy Screening Test-Sequencing System (FAST-SeqS) method, which was originally established as a simple, effective, noninvasive screening method for fetal aneuploidy from maternal blood.

RESULTS
We show that our modified FAST-SeqS method (mFAST-SeqS) can be used as a prescreening tool for an estimation of ctDNA percentage. With a combined evaluation of genome-wide and chromosome arm–specific z-scores from dilution series with cell line DNA and by comparisons of plasma-Seq profiles with data from mFAST-SeqS, we established a detection limit of ≥10% mutant alleles. Plasma samples with an mFAST-SeqS z-score &gt;5 showed results that were highly concordant with those of copy number profiles obtained from our previously described plasma-Seq approach.

CONCLUSIONS
Advantages of this approach include the speed and cost-effectiveness of the assay and that no prior knowledge about the genetic composition of tumor samples is necessary to identify plasma DNA samples with &gt;10% ctDNA content.

Published: April 2015

AbstractThe purpose of this paper was to present the current data on the risk of toxocarosis in humans in Poland and to give an overview of the clinical and diagnostic aspects of the disease. The number of reported clinical cases of Toxocara infection in children in Poland in medical literature has increased recently. The results of field surveys aimed to evaluate the soil contamination with geohelminth eggs conducted during the last few years showed that Toxocara is the most common zoonotic agent in urban public sites and in rural settlements. The questionnaire revealed rural inhabitants’ low awareness of zoonotic parasite threats to humans. In particular parents should be advised as to what proper preventive measures to undertake to eliminate the toxocarosis risk factors for children in rural environment. Prevention of initial environment contamination with Toxocara canis and T. cati eggs, which includes proper treatment regimes to eliminate patent infections in dogs and cats and preventing pets from defecating in public areas and private households is vital. To provide the public with suitably presented information as well as pet owners with uniform recommendations, a close collaboration between veterinary and public health professionals is crucial.
Parasitism underground: lice (Insecta: Phthiraptera) from Ctenomys talarum (Rodentia: Ctenomyidae) along its coastal distribution in Argentina
Authors: Martino Natalia S. , Romero Mariano D. , Malizia Ana I. 
Published: April 2015

AbstractSpecies of South American subterranean rodents belonging to the genus Ctenomys (commonly called tuco-tucos) are widely distributed across the southern Neotropical region. Despite their relatively well-studied biology and reproductive physiology, current knowledge of their ectoparasite fauna is limited to a few ambiguous studies, based on scattered samples from a small number of host individuals. Ctenomys talarum is the most widely distributed species in the genus. Lice (Phthiraptera) were collected from these tuco-tucos throughout their entire coastal range. Two species, one chewing louse (Gyropus parvus), and one sucking louse (Eulinognathus americanus) were collected. The distribution ranges for both louse species were extended with new locality records. No lice were found in two host populations. Furthermore, co-occurrence of both ectoparasites was not detected.

AbstractIn this study, we found unsporulated coccidia oocysts in passerines from the Nevado de Toluca National Park, Mexico. We captured birds and took samples of their droppings during three field visits. We examined a total of 72 fecal samples and found unsporulated coccidia oocysts in 10 samples from five passerine species: Atlapetes pileatus (3), Cardelina ruber (1), Mniotilta varia (1), Oreothlypis celata (2) and Regulus calendula (3). This appears to be the first recorded study of unsporulated coccidia oocysts in passerine species from Mexico
Two Procamallanus (Spirocamallanus) species (Nematoda: Camallanidae) from freshwater fishes in the Lower Congo River
Authors: Moravec František , Jirků Miloslav 
Published: April 2015

AbstractBased on light and scanning electron microscopical studies, one known and one previously undescribed Procamallanus (Spirocamallanus) species (Nematoda: Camallanidae) are described from specimens collected in the intestine of freshwater fishes in the Lower Congo River, Democratic Republic of Congo: P. (S.) daleneae (Boomker 1993) from Synodontis acanthomias Boulenger (Mochokidae, Siluriformes) (new host and geographical records) and P. (S.) parachannae sp. nov. from Parachanna insignis (Sauvage) (Channidae, Perciformes). The new species is most similar to P. (S.) serranochromis Moravec et Van As 2015, a parasite of African cichlids (Serranochromis spp.), differing from it mainly in the absence of any outgrowths on the female tail tip, a distinctly longer (546 μm) right spicule, a different length ratio of both spicules (1:2.6) and in the morphology of fourth-stage larvae. P. (S.) daleneae, a specific parasite of squeakers (Synodontis spp.), is redescribed; in contrast to the original description, the number of postanal papillae was found to be identical (6 pairs) with that of other related species.

Published: April 2015

AbstractAngiostrongylus vasorum (Nematoda: Angiostrongylidae) infection was detected at post-mortem examination in the pulmonary arteries and hearts of 34/102 (33,3%) of red foxes (Vulpes vulpes) from the Campania Region in southern Italy. Pathological changes consisted of granulomatous interstitial pneumonia caused by larvae and intravascular pulmonary adult nematodes. These changes confirm that angiostrongylosis infection in red foxes has a mainly chronic course, in which the infected host may disperse parasite larvae in the environment over its lifetime. Results suggest that the life cycle of A. vasorum is well established in the red fox in the Campania Region representing a potential infection risk for dogs.

AbstractThe pertraction of dysprosium (Dy) through a supported liquid membrane (SLM) system consisting of PTFE (polytetrafluoroethylene) support, D2EHPA (di-2-ethylhexyl phosphoric acid) dissolved in kerosene as membrane solution, and HNO3 solution as stripping solution, was studied. The experiments were designed by the Taguchi method in order to investigate the effects of initial Dy concentration, feed phase pH, different stripping solution concentration, and D2EHPA concentration in the membrane phase on Dy pertraction. Optimal experimental conditions for Dy pertraction were obtained using an analysis of variance (ANOVA) (feed concentration: 130 mg L

Published: April 2015

AbstractThe provenance of obsidian artefacts and raw materials was studied by the multivariate statistical analysis of forty-five samples using elemental composition data obtained by laser ablationinductively coupled plasma-mass spectrometry (LA-ICP-MS). One ICP-MS instrument equipped with a quadrupole mass filter and the other based on a time-of-flight analyser were coupled to the same type of laser ablation device (Nd:YAG 213 nm), thereby affording a comparison of the different mass spectrometers in terms of precision and verification of the consistency of the results. The influence of surface roughness (polished raw material vs artefact) and microinhomogeneity on the LA-ICP-MS signal was studied under the optimised working conditions of the laser ablation device. Principal component analysis, correspondence analysis, independent component analysis, multi-dimensional scaling, Sammon mapping and fuzzy cluster analysis were applied and compared in order to reveal statistically significant compositional differences between particular geological sites and to disclose the provenance of the raw materials used in manufacture of the artefacts. Twenty-seven artefacts and eighteen raw material samples from natural resources in the Czech Republic, Slovakia, Italy, Greece, Syria, Iraq, Turkey, Mexico and Nicaragua were examined with special attention focused on samples from Moravia (Czech Republic) and some Near East sites (Tell Arbid, Tell Asmar). The Carpathian origin of the obsidian artefacts was investigated in the Moravian samples using the Pb, Rb and U contents. The Near East samples were classified according to their Sr, Ba, Zr and REE contents as per-alkaline obsidians (Bingöl A/Nemrut Dağ) originating from Southeast Anatolia.
Promoting effect of group VI metals on Ni/MgO for catalytic growth of carbon nanotubes by ethylene chemical vapour deposition
Authors: Awadallah Ahmed E. 
Published: April 2015

AbstractThe incorporation of 1 mass % of group VI metals (chromium, molybdenum, and tungsten) into 4 mass % of Ni/MgO catalysts was evaluated for the synthesis of carbon nanotubes (CNTs) by the catalytic chemical vapour deposition of ethylene. All materials were characterised by XRD, surface area, TEM, SEM, Raman spectroscopy, and TGA-DTA. The resulting data demonstrated that the addition of group VI metals improved the surface area and metal dispersion, thereby achieving a remarkable enhancement in catalytic growth activity. Among the metals of group VI, Mo was found to be the most effective promoter for catalysing the CNTs’ growth. From TEM observation, long CNTs with a higher degree of graphitization were obtained on the Ni-Mo/MgO catalyst. TGA and DTA analysis showed that the as-grown CNTs over both Ni-Mo and Ni-W/MgO catalysts exhibited higher thermal stability.

Published: April 2015

AbstractThe dissolution kinetics of cerussite was investigated using methanesulphonic acid (MSA) as an alternative leaching reagent. The effects of particle size, stirring speed, acid concentration, and reaction temperature on the lead dissolution rate were determined. The dissolution process followed the kinetic law of the shrinking-core model, and a corresponding mixed control model was found suitable for representing the rate-controlling step. The mixed kinetic model comprised two stages: surface chemical reaction (283 K to 303 K) and diffusion through the product layer (303 K to 323 K). The activation energies of these sequential stages were 43.20 kJ mol

Published: April 2015

AbstractThe electrolytic deposition of nanosized Cu/Ni-Cu multilayer coatings on a paraffin-impregnated graphite substrate was performed from an electrolyte consisting of sulphate salts of the above metals and a complex-forming agent, sodium citrate. The multilayer Cu/Ni-Cu coatings were prepared using the potentiostatic method, in which the potential was alternately pulsed between the reduction potentials of the components. Suitable deposition potentials were selected from the polarisation curves. The presence of the thin films was confirmed by atomic absorption spectroscopy (after dissolution) and by optical microscopy. The resulting images show a layered structure of Cu/Ni-Cu coatings formed by Cu, Ni and/or Ni-Cu layers.

Published: April 2015

AbstractAn efficient ionic liquid with both Brønsted acidic and Lewis basic sites, namely 1,4-dimethyl-1- (4-sulphobutyl)piperazinium hydrogen sulphate (IL1), was synthesised and characterised. IL1 is a “green”, homogeneous and reusable catalyst for: i) the synthesis of pyranopyrazoles (Va-Vj) and benzopyrans (VIa-VIj and VIIa-VIIf) at ambient temperature under solvent-free conditions and ii) the synthesis of amino-2-chromenes (VIIIa-VIIIi and IXa-IXi) and dihyropyrano[c]chromenes (Xa- Xi) at 80◦C under solvent-free conditions. The reactions were rapid with excellent product yields. In addition, the double Brønsted acid, 1,4-dimethyl-1,4-bis(4-sulphobutyl)piperazinium hydrogen sulphate (IL2), was prepared to evaluate the cooperation efficiency of their Brønsted acidic and Lewis basic sites as compared with the double Brønsted acidic sites in IL1

Published: April 2015

AbstractThe practical synthetic preparation of glutaric acid has remained a major challenge to date. In the present study, glutaric acid was synthesised by way of one-pot diazoniation/hydrogenation of the readily available L-glutamic acid under aqueous conditions on a gram-scale with good yields. This is the first example of the deamination of the aliphatic primary amine via diazoniation and could afford a practical approach to the production of glutaric acid.
Swelling of N-vinylcaprolactam–dodecyl methacrylate gel in {heptane + toluene} mixtures
Authors: Sevgili Lutfullah M. , Toprak Serdar , Çavuş Selva 
Published: April 2015

AbstractA copolymer gel has been synthesized from N-vinylcaprolactam and dodecyl methacrylate in ethanol using the free radical cross-linking polymerization method. Characterizations of the gel were performed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermal gravimetric analysis (TGA) techniques. Swelling behavior of the gel was investigated in heptane, toluene, and their binary mixtures with different compositions. Swelling value in toluene is higher than that in heptane and swelling value increases with the increasing initial content of toluene in the binary mixture with heptane. The swelling values are correlated by the first- and second-order differential equations, and the best model correlating the experimental results is a second-order one. Diffusion coefficients have also been calculated for heptane and toluene at each concentration by power-law and first-order equations. While the diffusion mechanism of the gel in heptane is a Fickian one, the gel swelled in toluene exhibits a non-Fickian character. Diffusion mechanisms of the gels in binary mixtures are much more complicated. Because of the higher swelling degree in toluene compared to that in heptane, selectivity of the gel in different {heptane + toluene} mixtures with selectivity close to 1 has also been taken into consideration.
A polyacrylate prepared using polyurethane surfactants: properties of emulsion and film
Authors: Zheng Jie , Lu Man-Geng 
Published: April 2015

AbstractThe designed polyurethane surfactant (PUS) was used as a macromolecular surfactant for the preparation of polyacrylate emulsion without any other surfactants and stabilizers. The resultant polymer emulsion and film properties were compared with those of the emulsion prepared with sodium dodecyl sulfate (SDS). Long shelf-life of the polymer emulsion can be achieved at proper composition. Polymer particles show core-shell and nano-scale structure with narrow distribution. Thermoanalysis results show phase separation in the polymer film, which leads to gloss decrease with the PUS content increase. Such polymer films show good water resistance and mechanical strength.
