The compound MH-78 ((+/-)-1-(2,6-dimethylphenoxy)-3-{4-[2-(2-methoxyphenoxy)ethyl]-piperazin-1-yl}propan-2-ol dihydrochloride) contains structural elements that are typical for α1- and β-blockers. This study aimed to investigate the hypotensive activity as well as the in vitro and in vivo cardiovascular effects of a novel α1- and β-adrenoceptor antagonist (MH-78) and compare it with carvedilol and urapidil. The procedures were performed on aortic rings of normotensive anesthetized rats. MH-78 decreased the blood pressure and heart rate after intravenous and oral administration. MH-78 possesses both α1- and β-adrenoceptor blocking activity, which was confirmed in the in vivo study. In biofunctional assays, MH-78 displayed vasorelaxant activity due to α1-adrenoceptor antagonism and calcium channel blocking properties. Moreover, in endothelium-intact aortic rings, pretreatment with Nω-nitro-L-arginine methyl ester (L-NAME) and 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) reduced the MH-78-induced vasorelaxation to a level that is characteristic for MH-78 affinity to α1-adrenoceptors. Our results demonstrated that MH-78 possesses α1- and β-adrenoceptor blocking properties and induces potent hypotensive and vasorelaxant effects. Moreover, it relaxes vascular smooth muscle not only due to α1-adrenoceptor blocking activity, but also via the endothelium-dependent nitric oxide/soluble guanylyl cyclase/cyclic guanosine monophosphate signalling pathway.

Prostaglandin (PG) E2 has been implicated in the pathogenesis of aspirin-exacerbated respiratory disease (AERD). E-type prostanoid (EP) receptor 4 is known to confer inhibitory signals to eosinophils and monocytes, amongst others. In this study, we investigated whether the responsiveness of eosinophils and monocytes to PGE2 and EP4 receptor activation is altered in AERD patients. While the expression of the EP4 receptor in eosinophils was unaltered in AERD patients, inhibition of eosinophil chemotaxis by PGE2 or the EP4 agonist CAY10598 was less pronounced in AERD patients as compared to healthy control subjects. In monocytes, we found no changes in basal or lipopolysaccharide (LPS)-stimulated PGE2 synthesis, but the response to EP4 receptor activation with respect to inhibition of LPS-induced tumor necrosis factor-α release was reduced in AERD patients, especially in the presence of aspirin (acetylsalicylic acid). Our data point towards a decreased sensitivity of inhibitory EP4 receptor that may play a role in AERD.
Einheitliches ἀλέκτωρ + φωνέω für den Hahnenschrei im Neuen Testament?
Authors: Kraus Thomas J.
Published: December 2014

The four canonical gospels present the consistent sequence ἀλέκτωρ + φωνέω for the cock’s crow in Peter’s actual denial and its prediction by Jesus. The compound ἀλεκτοροφωνία in Mark 13:35 is the only alternative lexeme for the cock’s crow and, due to its single occurrence in the Greek Bible a hapax legomenon. In this study I follow up the variae lectiones in Matt 26:34 and 26:75, where the compound is backed by considerable and distinguished textual witnesses. By means of a validation of the attestation of these variae lectiones in the established critical editions of the New Testament it will be shown that their representation is often insufficient and incomplete. A speculative scenario will be created on the basis of the quality of the attestation of ἀλεκτοροφωνία in Matt 26:34 and 26:75 in order to make the compound plausible as the original reading. In addition, all this relativizes the importance and validity of the term hapax legomenon.

Two new species of Paraneseuthia Franz (Coleoptera, Staphylinidae, Scydmaeninae) from West Malaysia
Authors: JAŁOSZYŃSKI PAWEŁ
Published: December 2014

Two new species of Paraneseuthia are described from peninsular Malaysia: P. joeparkeri sp. n. from Bukit Larut (Maxwell Hill) and P. titiwangsana sp. n. from the Genting Highlands. The new species are morphologically allied to species known so far only from Sumatra; they all share emarginate apex of the aedeagus bordered at each side by a subtriangular projection and a pair of setae. This is the first record of this eutheiine genus from the Malay Peninsula and extends the known diversity of Paraneseuthia species within the historical Sundaland area.

Published: December 2014

Background: Thiamine plays a critical role in energy metabolism. Critically ill patients may have thiamine deficiency and increased mortality due to potentially irreversible consequences. The aim of this study was to show the impact of thiamine deficiency in a series of patients and the rapid response to thiamine replacement, showing the changes in clinical and metabolic conditions over time. Methods: We described 3 cases of hospitalized patients who had received parenteral nutrition (PN) without vitamin supplementation. All the patients were admitted to the ICU between 2010 and 2011 with a severe form of lactic acidosis, an unstable circulatory state, and a different neurological disorder (a lethargic state, a severe form of impaired near‐coma consciousness, and Wernicke encephalopathy). Results: Intravenous (IV) administration of thiamine was associated with a rapid and marked restoration of acid‐base balance, hemodynamic stability and the disappearance of neurological disturbances, and normalization of the clinical and biochemical conditions of all the patients within the following hours. Conclusions: The 3 cases demonstrated the rapidity of the reversal of severe thiamine deficiency, achieved by appropriate replacement in different hospitalized patients. The regression of clinical and biochemical disorders requires a prompt diagnosis and treatment based on the IV administration of thiamine and magnesium sulfate. In hospitalized patients at risk, thiamine deficiency is prevented by the integration of thiamine supplementation into PN and other forms of nutrition support.
Monosyllabic circumflexion or shortening?
Authors: Yamazaki Yoko
Published: December 2014

The Lithuanian 3rd person future forms of monosyllabic acute stems are mentioned as one of the categories where the examples of a phenomenon called “monosyllabic circumflexion” or “monosyllabic metatony” are found, e. g., dúoti - duõs ‛to give’. However, there are several exceptions, e. g., lìs (∼ lýti ‛to rain’), bùs (∼ buti ‛to be’), etc. Yet, the condition of the exceptions has not been fully analyzed in the context of the verbal system involving other tense paradigms. In this paper, a thorough examination will be conducted on the 3rd person future forms and their paradigms in Lithuanian. It is found that the verbs which have shortened 3rd person future forms always have the nasal infix present. Based on this result, a possible interpretation will be presented as to how certain 3rd person future forms have been shortened. Also, I will propose that the shortening of the 3rd person future forms is a secondary development, whereas MC could be the regular process for the 3rd person future forms.

Die Siegesstele des Amasis
Authors: Jansen-Winkeln Karl
Published: December 2014

Republication of the ‘Elephantine stela’ of Amasis, formerly Cairo 13/6/24/1, now in the Nubian ­Museum, Aswan. The inscription, in the Königsnovelle tradition, reports two episodes of the war between Apries and Amasis. The first part, dated to year 1 of Amasis, ­describes the counter-attack of Apries, with the help of Greek mercenaries, against the usurper Amasis (Oct./Nov. 570). Contrary to earlier assumptions, Apries’ fleet did not start from an ‘island’ (jw) but rather traveled down the Canopic arm (ᶜnw) of the Nile. The attackers were defeated by Amasis’ troops at Jmʿw. The second part concerns repulsing an invasion by Babylonian (‘Asiatic’) troops trying, in year 4 (March 567), to reinstall Apries as king, who was killed in the course of the battle.
Depletion Interaction Mediated by fd-Virus: on the Limit of Low Density and Derjaguin Approximation
Authors: De Sio Silvia , Lang Peter R.
Published: December 2014

Depletion potentials induced by the rod-like fd-virus between
colloidal probe spheres and a flat glass wall were measured using
total internal reflection microscopy. The objective of this
investigation was to determine the limits of the approximations used
for the theoretical description of the depletion pair potential. Data
were obtained at rod concentrations as high as 15 times their overlap
concentration and the size ratio between the rod length and the sphere
radius increased up to L/R = 1.76. With this, the basic
assumptions for low density approximation and Derjaguin approximation
were clearly violated. Nevertheless, we observed good agreement
between experimental data and predictions up to the highest size ratio
and in rod concentrations of seven times their overlap
concentration. Only at higher concentrations and at the lowest size
ratio investigated the experimental data deviate significantly from
the simple model.
Envejecimiento demográfico y migración interna de personas con 60 años y más de edad en Cuba y países de América Latina
Authors: López-Calleja Hiort-Lorenzen Cristina , Morejón Seijas Blanca
Published: December 2014

Este trabajo busca determinar comparativamente diferencias y semejanzas de características específicas de la población migrante interna con 60 años y más de edad entre las divisiones administrativas mayores (DAM) en Cuba y 14 países de América Latina. Se procesó información sobre migración interna de censos latinoamericanos de la década del 2000, proveniente de la página WEB del Centro Latinoamericano y Caribeño de Demografía (CELADE). Asimismo se presenta información relativa al envejecimiento de Cuba y los restantes países y se han calculado otros indicadores como porcentaje de migrantes y no migrantes, y también se estima un conjunto de indicadores expresivos de cierta propensión a migrar entre las DAM en los últimos 5 años previos al censo para la población de 60 y más años de edad. Se han empleado técnicas propias de la estadística, como tablas de contingencias, así como métodos de análisis estadístico de correspondencias simples y múltiples para explorar las relaciones existentes entre las categorías de las diferentes características demográficas de los migrantes en países seleccionados. Uno de los resultados muestra que en Cuba y el resto de la región aún no se observan signos de migración interna asociada a la salida de la actividad laboral, lo cual sucede a partir de los 60 años de edad en países desarrollados. Los análisis de correspondencia múltiple, permitieron conocer grupos afines de categorías de las variables estudiadas cuando estas se analizan simultáneamente. Así se encontró similitud entre Cuba y Chile por el valor de las variables de población con 60 años y más, esperanza de vida al nacer, tasa global de fecundidad e índice de envejecimiento. Las proporciones más elevadas de migrantes de “toda la vida” se observen en aquellos países que registran un mayor nivel relativo de desarrollo económico y social; Cuba, Argentina y en menor medida Chile, muestran los más altos porcentajes de población migrante reciente senescente; en Cuba, Chile, Argentina y Panamá el índice de envejecimiento alcanza los más elevados valores; Cuba se encuentra entre los países de más baja movilidad entre DAM, mientras que su nivel de mortalidad expresado en la esperanza de vida al nacer, es el más alto, junto con Chile y Costa Rica.

The Interactive Effects of PTSD, Emotion Regulation, and Anger Management Strategies on Female-Perpetrated IPV
Authors: Price Rachel Kendra , Bell Kathryn M. , Lilly Michelle
Published: December 2014

Research supports a relationship between posttraumatic stress disorder (PTSD) symptoms and intimate partner violence (IPV) perpetration, and theory implicates emotion regulation and anger management skills as probable moderators to that relationship (Chemtob, Novaco, Hamada, Gross, & Smith, 1997). However, no study has investigated these interactive relationships with female-perpetrated physical IPV. Therefore, this study examined the interactive effects of PTSD symptoms, emotion regulation, and anger management skills on female-perpetrated physical IPV. Female community members (N= 254) completed measures of PTSD symptoms, emotion regulation strategies, anger management skills during partner conflict, and IPV perpetration. Results indicated two-way interaction effects between emotion regulation and both PTSD symptoms and negative partner attributions. In addition, PTSD symptoms, emotion regulation, and escalating strategies marginally interacted to predict female-perpetrated IPV. Implications of these results for future research and interventions are discussed.
Use of laterally placed vacuum drains for management of aural hematomas in five dogs
Authors: Pavletic Michael M.
Published: December 2014

Case Description—5 dogs (a Newfoundland, Golden Retriever, Shiba Inu, Staffordshire Terrier, and Vizsla) were referred for evaluation and treatment of unilateral aural hematomas within a week after their formation.

Clinical Findings—Aural hematomas involved the left (3) or right (2) ears.

Treatment and Outcome—With patients under anesthesia, the aural hematomas were approached surgically from the convex, or lateral, pinnal surface. Two small incisions were used to position a vacuum drain into the incised hematoma cavity. The drain exited at the base of the pinna and adjacent cervical skin. The free end of the drain was attached to a vacuum reservoir for 18 to 21 days. Drains and skin sutures were removed at this time along with the protective Elizabethan collar. All hematomas resolved and surgical sites healed during the minimum 6-month follow-up period. Cosmetic results were considered excellent in 4 of 5 patients. Slight wrinkling of the pinna in 1 patient resulted from asymmetric enlargement of the cartilaginous walls of the hematoma, where vacuum application resulted in a slight folding of the redundant lateral cartilage wall.

Clinical Relevance—The described treatment was efficient, economical, and minimally invasive and required no bandaging or wound care. Placement of the drain tubing on the convex (lateral) aspect sheltered the system from displacement by patients with an Elizabethan collar in place. Overall cosmetic results were excellent; asymmetric enlargement of the cartilaginous walls of the hematoma with slight folding of the pinna was seen in 1 patient.
Lidocaine Sensitizes the Cytotoxicity of Cisplatin in Breast Cancer Cells via Up-Regulation of RARβ2 and RASSF1A Demethylation
Authors: Li Kehan , Yang Jianxue , Han Xuechang
Published: December 2014

It has been reported that lidocaine is toxic to various types of cells. And a recent study has confirmed that lidocaine exerts a demethylation effect and regulates the proliferation of human breast cancer cell lines. To recognize a potential anti-tumor effect of lidocaine, we evaluated the DNA demethylation by lidocaine in human breast cancer lines, MCF-7 and MDA-MB-231 cells, and determined the influence of demethylation on the toxicity to these cells of cisplatin, which is a commonly utilized anti-tumor agent for breast cancer. Results demonstrated that lidocaine promoted a significant global genomic demethylation, and particularly in the promoters of tumor suppressive genes (TSGs), RARβ2 and RASSF1A. Further, the lidocaine treatment increased cisplatin-induced apoptosis and enhanced cisplatin-induced cytotoxicity. The combined treatment with both lidocaine and cisplatin promoted a significantly higher level of MCF-7 cell apoptosis than singular lidocaine or cisplatin treatment. Moreover, the abrogation of RARβ2 or RASSF1A expression inhibited such apoptosis. In conclusion, the present study confirms the demethylation effect of lidocaine in breast cancer cells, and found that the demethylation of RARβ2 and RASSF1A sensitized the cytotoxicity of cisplatin in breast cancer cells.
Aquatic versus terrestrial attachment: Water makes a difference
Authors: Ditsche Petra , Summers Adam P
Published: December 2014

Animal attachment to a substrate is very different in terrestrial and aquatic environments. We discuss variations in both the forces acting to detach animals and forces of attachment. While in a terrestrial environment gravity is commonly understood as the most important detachment force, under submerged conditions gravity is nearly balanced out by buoyancy and therefore matters little. In contrast, flow forces such as drag and lift are of higher importance in an aquatic environment. Depending on the flow conditions, flow forces can reach much higher values than gravity and vary in magnitude and direction. For many of the attachment mechanisms (adhesion including glue, friction, suction and mechanical principles such as hook, lock, clamp and spacer) significant differences have to be considered under water. For example, the main principles of dry adhesion, van der Waals forces and chemical bonding, which make a gecko stick to the ceiling, are weak under submerged conditions. Capillary forces are very important for wet adhesion, e.g., in terrestrial beetles or flies, but usually do not occur under water. Viscous forces are likely an important contributor to adhesion under water in some mobile animals such as torrent frogs and mayflies, but there are still many open questions to be answered. Glue is the dominant attachment mechanism of sessile aquatic animals and the aquatic realm presents many challenges to this mode of attachment. Viscous forces and the lack of surface tension under submerged conditions also affect frictional interactions in the aquatic environment. Moreover, the limitation of suction to the pressure difference at vacuum conditions can be ameliorated under water, due to the increasing pressure with water depth.
ENHANCING COPPER AND LEAD BIOACCUMULATION IN RAPESEED BY ADDING HEMP SHIVES AS SOIL NATURAL AMENDMENTS
Authors: TANASE Corneliu , VOLF Irina , POPA Valentin I.
Published: December 2014

The current study reveals the results of a phytoremediation process applied to a multi metal contaminated soil, located in close proximity to an energy power plant. Phytoremediation process was studied using the rapeseed cultivation, both in the presence and absence of hemp shives, considered as potential natural soil amendments. The physiological responses of the rapeseed plants, such as variations in length and accumulation of biomass, as well as the content of assimilating pigments were investigated. The concentrations of Cu (II) and Pb (II) ions have also been determined in soil and plants aiming at locating the metal ions in different organs of the plants. By using hemp shives as amendments, bioaccumulation of copper and lead ions in plant increases. The plants cultivated in the presence of high amounts of heavy metal ions have been characterized by an inhibition of growth and development that consisted in decrease of root and stem lengths, as well in the amount of biomass accumulated in different vegetative organs.
Analysis of the Eco-Efficiency Change of Chinese Provinces

Published: December 2014

Eco-efficiency, being a matter of concern all over the world, is gaining increasing attention in the fields of economic and environment. This paper just investigates the relationship between economic development and environmental sustainability in Chinese provinces focused on the eco-efficiency calculation. In this paper, by the index of eco-efficiency into economic effect (er) and environment effect (ee), thus an effect matrix is framed; and a new method that can analyze the relationship between the economic development and environment sustainability is outlined and applied to evaluate the eco-efficiency change of 31 provinces of China during 2006-2010. Empirical results show that Beijing city is found to be the only one that has improved its eco-efficiency in the absolutely strong sustainability paradigm at all three environmental impacts; while most of other areas have taken on a paradigm of weak sustainability at some specific environmental impact; the country as a whole presents a weak sustainability paradigm for its solid waste production and the absolutely strong sustainability one both in its waste water and SO2 emission production. The effect matrix analysis constitutes a new way to assess the change of the eco-efficiency in an area, which seems very promising to judge the state of an area's eco-efficiency change toward sustainability and provides the sound foundation to support policy making.
O registro geológico da atividade antropogênica na região do Valo Grande, Estado de São Paulo, Brasil
Authors: Italiani Diana Melo , Mahiques Michel Michaelovitch
Published: December 2014

Após a abertura do canal artificial do Valo Grande, na primeira metade do século XIX, a região do Sistema Estuarino-Lagunar de Cananéia-Iguape, denominada Mar Pequeno, vem sendo influenciada por um intenso processo de assoreamento que mudou, numa curta escala de tempo, a morfologia e sedimentação do local, com a consequente formação de um delta intralagunar antropogênico. Essas evidências foram abordadas e analisadas neste trabalho por meio da elaboração de modelos digitais de terreno, realizados a partir de dados batimétricos obtidos em campo. Além disso, com a elaboração de mapas vetoriais realizados a partir da digitalização da linha de costa de imagens de satélite e mapas topográficos, foi possível fazer um estudo da mudança geomorfológica da linha de costa. O processo de erosão do Valo Grande foi demonstrado através de comparações das seções de perfis batimétricos efetivadas nos anos de 1891 e 1907 pela Comissão Geográfica e Geológica do Estado de São Paulo e dos perfis adquiridos em campo no ano de 2008, com a finalidade de obter a variação da largura e da profundidade do canal ao longo desses anos.

Published: December 2014

As abóboras (Cucurbita spp, Cucurbitaceae) são muito utilizadas na alimentação humana devido seu elevado valor nutricional, porém nem todas as suas partes são aproveitadas, como as sementes. São utilizadas há muito tempo na medicina popular como vermífugo. Fatores como propriedades nutricionais, sabor agradável ao paladar, fácil acesso e baixo custo são alguns fatores que contribuem para que sementes de abóbora façam parte da alimentação diária da população seja ela na forma de complemento ou como snacks. Pensando nisso verificou-se a composição química e nutricional da semente de abóbora (Cucurbita spp) comercializadas salgadas, para comprovar dados da literatura em relação aos seus efeitos, e a quantidade de sódio presente. O elevado teor de fibras encontrado (29,01g±0,28) sugere a eficácia das sementes de abóbora na ação hipoglicemiante e laxativa e o baixo teor de carboidratos (5,36g) sugere seu consumo como benéfico para diabéticos, visto que necessitam de dietas com baixos teores de carboidratos. No entanto, por serem estas comercializadas salgadas, seu consumo deve ser de forma moderada uma vez que uma porção perfaza 23% do valor diário permitido de sódio.

Authors: BALBI M. E. , OLIVEIRA K. , CHIQUITO R. F.
Published: December 2014

A quinoa (Chenopodium quinoa, Willd.) é um pseudocereal originário dos Andes, o plantio no Brasil se iniciou na década de 90 e tem ganhado lentamente a mesa do brasileiro. É muito consumida na forma de grãos, como farinha e em flocos. Nesse presente trabalho, tivemos por objetivo, investigar os nutrientes presentes na quinoa, assim como teor de saponina e absorção de água em meio à frio e à quente. A partir das análises da composição nutricional, observou-se que dos macronutrientes: carboidratos, proteínas e lipídios, foram representados respectivamente por 64,85%, 13,49% e 1,49%, enquanto fibras representaram 6, 60%, em 100g de quinoa em grãos. A quinoa é um alimento isento de glúten, sendo uma excelente opção para pacientes celíacos, comparada com outros dois alimentos isentos de glúten, milho e arroz integral,  apresentou quantidades superiores de nutrientes. Conforme dados literários foi confirmado através da análise qualitativa da saponina, que esta se encontra presente na superfície do grão in natura, a qual pode ser removida facilmente por técnicas de extração. Na hidratação da quinoa à quente foi expressiva comparado com a hidratação à frio, devido ao amido presente na quinoa ser hidratado em temperaturas superiores a 60ºC. Portanto, conclui-se que a quinoa é um alimento alternativo para a população e estudos sobre este grão são de extrema importância devido a sua alta composição nutricional.

Frente às demais emissões globais nos setores de emissões de CO2, apesar de apresentar um dos menores índices e parecer ser mínima a contribuição do setor aéreo no aquecimento global, estas são mais prejudiciais quando contrapostas às demais contribuições globais, uma vez que os poluentes lançados pelas aeronaves potencializam os efeitos do dióxido de carbono por conta das elevadas altitudes em que os aviões decolam (alta troposfera e baixa estratosfera), incidindo diretamente sobre as concentrações de gases do efeito estufa, intensificando o fenômeno do aquecimento global. Visando a evolução da demanda por energia e combustíveis, atrelados as necessidades de redução da emissão de poluentes, novas tecnologias vem sendo desenvolvidas para a aplicação e utilização das energias renováveis. Com as projeções de crescimento da aeronáutica, busca-se alternativas que reduzam a emissão de gases de efeito estufa e que minimizem a dependência dos preços do petróleo.

The Radical-Chain Addition to Double Molecular Bonds by the Nonbranched-Chain Mechanism: Low-Reactive Free Radicals Shortening Kinetic Chains
Authors: Silaev Michael M.
Published: December 2014

Five reaction schemes are suggested for the initiated nonbranched-chain addition of free radicals to the multiple bonds of the unsaturated compounds. The proposed schemes include the reaction competing with chain propagation reactions through a reactive free radical. The chain evolution stage in these schemes involves three or four types of free radicals. One of them is relatively low-reactive and inhibits the chain process by shortening of the kinetic chain length. Based on the suggested schemes, nine rate equations (containing one to three parameters to be determined directly) are deduced using quasi-steady-state treatment. These equations provide good fits for the nonmonotonic (peaking) dependences of the formation rates of the molecular products (1:1 adducts) on the concentration of the unsaturated component in binary systems consisting of a saturated component (hydrocarbon, alcohol, etc.) and an unsaturated component (olefin, allyl alcohol, formaldehyde, or dioxygen). The unsaturated compound in these systems is both a reactant and an autoinhibitor generating low-reactive free radicals. A similar kinetic description is applicable to the nonbranched-chain process of the free-radical hydrogen oxidation, in which the oxygen with the increase of its concentration begins to act as an oxidation autoingibitor (or an antioxidant). The energetics of the key radical-molecule reactions is considered.
New data aid estimate of ocean's plastic content
Authors: Wendel JoAnna
Published: December 2014

Experts estimate that 5.25 trillion plastic particles—weighing in at nearly 269,000 tons—are floating in the world's oceans. A new paper in the open access journal PLOS ONE (doi:10.1371/journal.pone.011191) about the abundance of plastic in the oceans combines data from 24 expeditions between 2007 and 2013. These expeditions cover all five subtropical gyres—areas of high pressure where seawater churns and sinks—as well as Australian coastal waters, the Bay of Bengal, and even the Mediterranean Sea.
Improving hydrology models for a changing climate
Authors: Palus Shannon
Published: December 2014

Changes over time in the relationship between rainfall and catchment runoff pose a significant challenge for hydrological models, which are often calibrated under the assumption that the future relationship will be consistent with that of the past. In a recent paper, Westra et al. outlined a method for diagnosing, interpreting, and improving the capacity of models to develop predictions under such conditions.

Published: December 2014

Background

Although laparoscopic major hepatectomy (MH) is becoming increasingly common in several specialized centres, data regarding outcomes are limited. The aim of this study was to identify the risk factors for postoperative complications of purely laparoscopic MH at a single centre.

Methods

All patients who underwent purely laparoscopic MH between January 1998 and March 2014 at the authors' institution were enrolled. Demographic, clinicopathological and perioperative factors were collected prospectively, and data were analysed retrospectively. The dependent variables studied were the occurrence of overall and major complications (Dindo–Clavien grade III or above).

Results

A total of 183 patients were enrolled. The types of MH included left-sided hepatectomy in 40 patients (21·9 per cent), right-sided hepatectomy in 135 (73·8 per cent) and central hepatectomy in eight (4·4 per cent). Median duration of surgery was 255 (range 100–540) min, and median blood loss was 280 (10–4500) ml. Complications occurred in 100 patients (54·6 per cent), and the 90-day all-cause mortality rate was 2·7 per cent. Liver-specific and general complications occurred in 62 (33·9 per cent) and 38 (20·8 per cent) patients respectively. Multivariable analysis identified one independent risk factor for global postoperative complications: intraoperative simultaneous radiofrequency ablation (RFA) (odds ratio (OR) 6·93, 95 per cent c.i. 1·49 to 32·14; P = 0·013). There were two independent risk factors for major complications: intraoperative blood transfusion (OR 2·50, 1·01 to 6·23; P = 0·049) and bilobar resection (OR 2·47, 1·00 to 6·06; P = 0·049).

Conclusion

Purely laparoscopic MH is feasible and safe. Simultaneous RFA and bilobar resection should probably be avoided.

Porosity in catalyst particles is essential because it enables reactants to reach the active sites and it enables products to leave the catalyst. The engineering of composite‐particle catalysts through the tuning of pore‐size distribution and connectivity is hampered by the inability to visualize structure and porosity at critical‐length scales. Herein, it is shown that the combination of phase‐contrast X‐ray microtomography and high‐resolution ptychographic X‐ray tomography allows the visualization and characterization of the interparticle pores at micro‐ and nanometer‐length scales. Furthermore, individual components in preshaped catalyst bodies used in fluid catalytic cracking, one of the most used catalysts, could be visualized and identified. The distribution of pore sizes, as well as enclosed pores, which cannot be probed by traditional methods, such as nitrogen physisorption and isotherm analysis, were determined.
An exploratory study of explosion potential of dust from torrefied biomass
Authors: Boskovic Andrej , Basu Prabir , Amyotte Paul
Published: December 2014

Torrefaction makes biomass brittle, and as such it is likely to produce more dusts during handling and transportation. So, it could increase the risk of explosion in plant using torrefied biomass. As the torrefaction technology enters commercial market the safety aspect of torrefied wood becomes important. The present paper is one of the first examinations of the question if torrefaction makes the biomass dust more explosive. Effects of torrefaction conditions on two important parameters that define the explosivity of a dust, i.e., minimum ignition temperature (MIT) and minimum explosible concentration (MEC) were studied. Above parameters were measured for Poplar wood before and after torrefaction. Three different particle size distributions of the wood, torrefied at 200, 250 and 300 °C, were tested. Exploratory experiments reported here found negligible effect of torrefaction on measured values of;Deg;ME;Deg;C and MIT of biomass. However, torrefied particles larger than 100 micron showed higher values of MIT than that for raw biomass.
New vinylester‐based monoliths as a new stationary phase for capillary electrochromatography
Authors: Kip Çiğdem , Tuncel Ali
Published: December 2014

Vinyl ester‐based monoliths are proposed as a new group of stationary phase for CEC. The capillary monolithic columns were prepared by using two vinyl ester monomers, vinyl pivalate (VPV), and vinyl decanoate (VDC) by using ethylene dimethacrylate (EDMA) as the cross‐linking agent, and 2‐acrylamido‐2‐methylpropane sulfonic acid as the charge‐bearing monomer. The monoliths with different pore structures and permeabilities were obtained by varying the type and composition of the porogen mixture containing isoamyl alcohol and 1,4‐butanediol. The electrochromatographic separation of alkylbenzenes was successfully performed by using an acetonitrile/aqueous buffer system as the mobile phase in a CEC system. Vinyl ester monoliths with short alkyl chain length (i.e. poly(VPV‐co‐EDMA) exhibited better separation performance compared with the monolith with long alkyl chain length (i.e. poly(VDC‐co‐EDMA). In the case of VPV‐based monoliths, the theoretical plate numbers higher than 250 000 plates/m were achieved by using a porogen mixture containing 33% v/v of isoamyl alcohol. For both VDC and VPV‐based monoliths, the column efficiency was almost independent of the superficial velocity in the range of 2–12 cm/min.

A delay discounting task produces a greater likelihood of waiting than a deferred gratification task
Authors: Young Michael E. , McCoy Anthony W.
Published: December 2014

A first‐person‐shooter video game was adapted for the study of choice between smaller sooner and larger later outcomes to compare the behavioral patterns produced by deferred gratification (DG) and delay discounting (DD) tasks. Participants played a game in which they could either fire their weapon sooner and do a small amount of damage or wait a few seconds to fire their weapon and do a larger amount of damage. For the DD task, a failure to fire within one second committed the player to waiting for the larger later outcome thus removing the opportunity to defect during the delay that is present in the DG task. The incentive structure changed multiple times during game play so that at times the optimal decision was to choose the smaller sooner outcome whereas at other times the optimal decision was to wait for the larger later outcome. Players assigned to the DD task showed a greater tendency to wait and lower sensitivity to the changing incentives.
Liquid chromatography with diode array detection combined with spectral deconvolution for the analysis of some diterpene esters in Arabica coffee brew
Authors: Erny Guillaume L. , Moeenfard Marzieh , Alves Arminda
Published: December 2014

In this manuscript, the separation of kahweol and cafestol esters from Arabica coffee brews was investigated using liquid chromatography with a diode array detector. When detected in conjunction, cafestol, and kahweol esters were eluted together, but, after optimization, the kahweol esters could be selectively detected by setting the wavelength at 290 nm to allow their quantification. Such an approach was not possible for the cafestol esters, and spectral deconvolution was used to obtain deconvoluted chromatograms. In each of those chromatograms, the four esters were baseline separated allowing for the quantification of the eight targeted compounds. Because kahweol esters could be quantified either using the chromatogram obtained by setting the wavelength at 290 nm or using the deconvoluted chromatogram, those compounds were used to compare the analytical performances. Slightly better limits of detection were obtained using the deconvoluted chromatogram. Identical concentrations were found in a real sample with both approaches. The peak areas in the deconvoluted chromatograms were repeatable (intraday repeatability of 0.8%, interday repeatability of 1.0%). This work demonstrates the accuracy of spectral deconvolution when using liquid chromatography to mathematically separate coeluting compounds using the full spectra recorded by a diode array detector.
A high‐order multi‐moment constrained finite‐volume global shallow‐water model on the Yin‐Yang grid
Authors: Li Xingliang , Chen Chungang , Xiao Feng , Shen Xueshun
Published: December 2014

A high‐order global shallow‐water model on a Yin‐Yang grid has been developed by using the multi‐moment constrained finite‐volume (MCV) method. Unlike the traditional finite‐volume method, more degrees of freedom (DOFs)–which are the values at the solution points within each mesh element–are defined and updated in time. The time evolution equations for these point values (PVs) are derived from a set of constraint conditions in terms of the so‐called multi‐moment quantities, such as the PV, the volume‐integrated average (VIA) and derivative. Different moments use different forms of equations which are all consistent with the shallow‐water equations, among which the VIA moment is computed from a finite‐volume formulation of flux form that guarantees rigorous numerical conservation. A fourth‐order formulation is devised with the third‐order reconstruction built over each element using the DOFs locally available. A simple and orthogonal overset grid, the Yin‐Yang grid, is used to represent the spherical geometry with quasi‐uniform grid spacing. The resulting global shallow‐water model is attractive in algorithmic simplicity and computational efficiency. The model has been validated by widely used benchmark tests. The numerical results of the present model are competitive with most existing advanced models.
