Published: April 2017

While synoptic collections provide data on the range and general composition of the North American bee fauna, bee communities associated with specific habitats are largely uncharacterized.  This report describes the community of native bees currently found in remnant fragments of the Palouse Prairie of northern Idaho and southeastern Washington State.  Native bees were collected using standardized collection techniques including blue vane traps, colored pan traps and aerial netting.  More than 13,000 individuals were collected, representing at least 174 species and 36 morphospecies in 29 genera.  These data provide the most thorough characterization of the bee fauna of this vulnerable ecosystem, as well as community level information on bee species of unknown conservation status.  These results are relevant to regional conservation efforts and, more broadly, are representative of conditions in fragmented grasslands surrounded by intense agriculture, a common global land use pattern of conservation concern.

Authors: Cong H H , Sibgatullina R R , Khabibrakhmanova A M , Kurbangalieva A R , Ziganshina L E
Published: April 2017

Aim. Study of the possibility of using cell experimental models (erythrocytes hemolysis and platelet aggregation) for screening for anti-inflammatory activity of novel synthesized 5(S)-menthyloxy derivatives of 2(5Н)-furanone (compounds R1-R6).

Methods. Evaluation of membrane-stabilizing activity of the test compounds was performed by means of models of erythrocyte hemolysis induced by hypotonic environment (osmotic hemolysis) and free radicals. Antiplatelet effect of the compounds was studied by inducing platelet aggregation by 1 mM arachidonic acid. Study of anti-inflammatory activity of novel potential anti-inflammatory molecules was performed with the use of the model of carrageenan-induced paw edema in mice.

Results. Compounds R1, R2, R3, and R4 increase the degree of osmotic hemolysis. Compounds R5, R6 decrease the intensity of hemolysis at different concentrations. Compounds R1, R2, R4 and R6 promote free-radical erythrocyte membrane damage at all tested concentrations. Compound R3 protects erythrocytes at low concentrations and promotes erythrocyte damage with increasing concentration. Compound R5 protects erythrocytes at concentrations 3×10-9 и 3×10-5 М. Compounds R1, R2, R4 enhance platelet aggregation at different concentrations. Compound R3 inhibits platelet aggregation at concentration 10-6 М, and at concentrations 10-8 and 10-5 М it induces platelet aggregation. Compound R5 does not affect platelet aggregation. Compound R6 inhibits platelet aggregation at all tested concentrations. On the basis of the results obtained from in vitro test systems compound R6 was selected for further studies of anti-inflammatory activity as it demonstrated maximum effect based on two out of three evaluation criteria. Compound R6 posseses anti-inflammatory activity in the model of inflammation.

Conclusion. The novel derivative of 2(5Н)-furanone bearing l-menthol moiety (compound R6) protects erythrocyte membrane from damaging action of hypotonic environment, inhibits platelet aggregation and demonstrates anti-inflammatory activity; cell experimental models can be used for the first phase of screening of novel chemical compounds for anti-inflammatory activity.

Authors: Nedomolkina S A , Velikaya O V , Zoloedov V I
Published: April 2017

The review article is devoted to an actual problem of modern medicine - combined pathology of chronic obstructive pulmonary disease and type 2 diabetes mellitus. These 2 diseases take the first place in the structure of people’s mortality. The rate of chronic obstructive pulmonary disease and type 2 diabetes mellitus increases annually along with life length and according to different data reaches 35.8%. In the article scientists’ modern perception and known facts from scientific literature are presented. Special attention is given to cytokine status in chronic obstructive pulmonary disease and type 2 diabetes mellitus. Cytokines classification based on mechanism of action and their role in pathogenesis is presented. Systemic inflammation characteristic for both diseases presents as the increase of pro-inflammatory cytokines level in the blood and decrease of anti-inflammatory cytokines. Determining cytokines in patients with chronic obstructive pulmonary disease and type 2 diabetes mellitus has prognostic value. Mutual negative influence of these two diseases is directly associated with the increase of pro-inflammatory cytokines which are considered the reason for insulin resistance and type 2 diabetes mellitus. Despite the attempts to study cytokine status in patients with chronic obstructive pulmonary disease and type 2 diabetes mellitus the issues of treatment of combined pathology, diagnostic concentration of pro-inflammatory and anti-inflammatory cytokines, their role in pathogenesis and clinical presentation are still an open question. Certainly it is necessary to continue studying the cytokine status in patients with chronic obstructive pulmonary disease and type 2 diabetes mellitus to answer those questions.

Authors: Vatankha S S , Aliev F Yu
Published: April 2017

Aim. To evaluate efficacy of radioisotopic methods in detection of metastatic involvement of sentinel lymph nodes for choosing further theurapeutic tactics.

Methods. The study group included 23 females with confirmed breast cancer. Sentinel lymph nodes were detected by isotope 99mTc Nanocolloid and blue dye in General Electric gamma camera (USA).

Results. In all cases patients’ age was 45 to 60 years. In 16 (69.5%) cases the tumor size was below 5 cm which corresponded to clinical stage 2, in other 7 (30.5%) patients the tumor size was below 2 cm. Positive results with the use of lymphoscintigraphy were revealed in 6 (26%) cases, all results were morphologically confirmed straight after lymph node removal. In 5 (83%) cases metastatic involvement of the node was observed in stage 2 cancer. Such patients were immediately referred to radical mastectomy with radical lymph node dissection. In other cases pathological accumulation of a radiopharmaceutical was not observed. Only in one case after removal of such node its metastatic involvement was confirmed histologically. So the frequency of false negative results was 4.3%. Respectively, status of sentinel lymph nodes in breast cancer reflects the status of lymphatic collector with 95.7% accuracy.

Conclusion. The biopsy results demonstrated high diagnostic value of lymphoscintigraphy for detection of breast cancer metastases to sentinel lymph nodes (sensitivity 86%, specificity 100%): the method can be successfully used in early stages of breast cancer and also in case of negative results of conventional diagnostic methods (ultrasound, roentgen mammography).

Published: April 2017

RESUMO: As rearticulações contemporâneas do neoliberalismo têm promovido o aprofundamento das transformações na instituição central da modernidade. O Estado e todas suas instituições, e aqui se destaca o Poder Judiciário, tem passado por importantes redimensionamentos. Neste contexto, o presente artigo, construído por meio de uma revisão bibliográfica interdisciplinar, enfrenta o conjunto de câmbios que passa a jurisdição, dentro do cenário multifacetado de crises estatais. Partindo do reconhecimento de que na globalização tem-se a instauração de uma nova racionalidade que “orienta o mundo”, traz a reflexão sobre a forma como o espaço judicial tem tido redefinidas as funções e a operacionalidade, em face das demandas por uma gestão eficiente. A hipótese de trabalho envolveu a compreensão de que as mudanças pelas quais passa o sistema de justiça estão orientadas por discurso que sacrifica a justiça sob o primado do aumento da produtividade e diminuição das despesas. Assim, a racionalidade econômica-concorrencial passa a impor diretrizes gerencias ao sistema de justiça, o que se repercute no sacrífico da base de legitimidade material de atuação.PALAVRAS-CHAVE: Neoliberalismo, Crises do Estado, Jurisdição. ABSTRACT: The contemporary neoliberalism rearticulations has further the deepening of the central institution of modernity. The State and all its institutions, and here the Judiciary Power enhance, has been through important resizes. In this context, this paper, built by an interdisciplinary literature review, faces the exchange set that jurisdiction passes, inside a multifaceted scenario of State Crisis. Starting from the recognition that in the globalization there are the establishment of a new rationality that “guides the world”, brings the reflection about how the shape of the judicial space has been redefined it functions and the operability, in view of demands for an efficient management. The working hypothesis has involved the understanding that the changes that the justice system has been through are guided by a speech that sacrifices the justice beneath increase of the productivity and the reducing expenditure. So, the economic-competitive rationality starts to impose management guidelines to justice system, which impact on the sacrifice of the basic legitimacy of acting material.  KEYWORDS: Neoliberalism, State Crisis, Jurisdiction

Detection of water abundance in Baluran National Park with landsat satellite imagery analysis
Authors: Harjadi Beny
Published: April 2017

Indonesia is one of the mega-biodiversity countries that have a great responsibility in maintaining the balance of the global climate and forest ecosystems. Drought causes shifting of ecosystems causing disturbances on animal life leading to death of species. Alongside fires in the savanna, drought is a recurrent problem in the park, which occurs every year. This study aims to detect the abundance of water by using satellite imagery in Baluran National Park (BNP). The research analyzed using Landsat satellite imagery ETM7 + in 1999 and 2010 and three (3) main factors that have great potential abundance of water, are: (1) plant density (GI = Greenness Index), (2) soil moisture (WI = Wetness Index), and (3) soil conditions (SBI = Soil Brightness Index). Three factors are summed and divided by three to get 5 levels of water abundance: 1) Very abundant, 2) Abundant, 3) Medium, 4) Few, and 5) Very little. The results showed that the abundance of water decreased between 1999 and 2010 for moderate conditions from 85% to 38%, if the abundance of low water (slightly) increased from 15% to 60%. The level of accuracy of the abundance of water in the field of more than 80% is exactly 91%. The extreme drought conditions will be very dangerous for the survival of flora and fauna in Baluran National Park that are in desperate need of water and potentially in danger of a fire. Construction of water reservoirs and water supply continuously using a water tank in the dry season is very necessary in the Baluran National Park.
Prediction of water discharge and sediment in teak forested area using artificial neural network model
Authors: Wahyuningrum Nining
Published: April 2017

Information on the relationship of rainfall with discharge and sediment are required in watershed management.This relationship is known to be highly nonlinear and complex. Although discharge and sediment has been monitored continuously, but sometimes the information is not or less complete. In this condition, modeling is indispensable.The research objective is to create a model to predict the monthly direct runoff and sediment using Artificial Neural Network (ANN).The model was tested using rainfall data at t-3 and t-4 as input, and discharge and sediment at t+3 and t+4 as output. The data used is the data from 2001 to 2014. The results showed that of some models tested there are two models for the prediction of discharge and two models for sediment.The model was chosen because it has the smallest MSE, the largest R2 and satisfying K (0.5 to 0.65).Thus, these models can be used to predict discharge andsediment for a period of t+3 and t+4. Prediction of discharge of t+3 and t+4 may use Q t+3 = 0,64 Q t-3 + 0,05 and Q t+4 = 0,65 Q t-4 + 0,074 res pectively, while for predicting sediment of t+3 and t+4 may use equations QS t+3 = 0,45 QS t-3 + 0,052 and QS t+4 = 0,45 QS t-4 + 0,052. This ANN modeling can be applied to predict the flow and sediment in other locations with an architecture adapted to the conditions of available data.
Consequences of lysine auxotrophy for Candida albicans adherence and biofilm formation
Authors: Gabriel Iwona , Rychłowski Michał
Published: April 2017

A number of factors are known to be involved in Candida albicans virulence although biofilm development on the surfaces of indwelling medical devices is considered to promote superficial or systemic disease. Accordingly to previously reported up-regulation of saccharopine and acetyllysine in biofilm cells and activation of the lysine biosynthesis/degradation pathway we investigated the consequences of Candida albicans lysine auxotrophy on adhesion to host tissues and biofilm formation. Our data indicate that mutant strains lysD21/lysD22, defective in homocitrate synthase and lysD4, homoaconitase activity (two first a-aminoadipate pathway enzymes) are able to adhere to mouse embryonic fibroblast cell line (NIH/3T3) with the same extent as control strain SC5314. On the other hand auxotrophic mutant strains development on mouse fibroblasts monolayers was significantly reduced up to 5h of infection. Although invasion into human-derived oral epithelial cells was unaltered, both mutant strains formed significantly different biofilm architecture and demonstrated diminished viability during long term biofilm propagation.
Complexidade e transdisciplinaridade: convites para a colaboração e corresponsabilidade educativa
Authors: Moraz Andreia de Andrade , Strieder Roque
Published: April 2017

Somos reféns de uma organização social enraizada em uma extensa lista de dispositivos de ordem, que geram grave crise pedagógica e educacional. Diante desse contexto e da lógica racional dos conhecimentos, e considerando a etimologia de complexus (o que é tecido junto), no trabalho indicamos a transdisciplinaridade como oportunidade de articular os elementos contraditórios desse “tecido junto” também no aspecto pedagógico e formativo. Fruto de reflexões teóricas, sugerimos a complexidade para reconhecer a emergência de diferentes níveis de realidades, seja das coisas do mundo, da vida, seja das organizações humanas, e como uma possibilidade para alargar a compreensão do real pela abertura e aceitação da presença auto-organizativa em cada ser humano. Concluímos: essa abordagem cria sensibilidade para a responsabilidade na transformação de si, do outro e do mundo.
Saberes-fazeres que atravessam a educação do campo
Authors: Conte Isaura Isabel , Ribeiro Marlene
Published: April 2017

Neste texto abordam-se os saberes-fazeres, ou conhecimentos, de uma escola de educação do campo e alguns dilemas do contexto atual no desenvolvimento do processo pedagógico. As reflexões são oriundas de pesquisa participante, compreendendo estudos teóricos e intervenções empíricas. Utilizamo-nos de entrevistas gravadas e conversas direcionadas a docentes, funcionários técnicos e discentes, além de análise documental do PPP da escola. Enfatizamos que a formação dos profissionais atuantes na instituição merece ser pensada no contexto das escolas do campo, inclusive no que diz respeito ao acesso e à qualidade dessa formação. Há esforço pessoal por parte dos profissionais em relação às práticas, entretanto há questões que fogem ao seu alcance, inclusive no que se refere à saída dos jovens do campo por falta de políticas sociais como acesso à terra.

Published: April 2017

Com este trabalho objetivou-se investigar as influências das áreas específicas de conhecimento dos professores de uma Instituição de Ensino Superior (IES) pública nos movimentos da docência universitária e discutir potenciais indicadores que caracterizam uma Pedagogia Universitária das licenciaturas nas áreas de Ciências Humanas (CH) e Linguística, Letras e Artes (LLA). O trabalho foi realizado a partir das narrativas de 13 docentes. A pesquisa é qualitativa, de cunho narrativo (CONNELLY; CLANDININ, 1995; MCEVAN, 1998), e os achados foram submetidos à Análise Textual Discursiva (MORAES; GALIAZZI, 2007). Concluiu-se que as licenciaturas possuem aspectos convergentes e divergentes que evidenciam que pedagogias específicas podem ser configuradas com estratégias formativas próprias para a docência.

Authors: De Almeida Frederico
Published: April 2017

Este texto tem por objetivo apresentar um relato de observação de um encontro de advogados populares brasileiros no início dos anos 2000. Embora trate-se de um relato isolado, exploratório e datado, acredita-se que sua publicação pode contribuir para outros estudos sobre o mesmo objeto, por representar uma fonte rica de informações sobre um objeto ainda pouco estudado; e por trazer dados sobre essa modalidade de advocacia politicamente orientada em um momento de mudanças nas relações desse grupo profissional com o Estado, o direito, os governos e as instituições de justiça. Ao final, os dados extraídos do relato de observação são analisados em face da literatura sobre a relação entre advogados e política, a fim de se apresentar explicações e hipóteses a serem desenvolvidas sobre a advocacia popular contemporânea no Brasil.

As Flutuações do nível do mar e mudanças climáticas durante o Holoceno foram importante para construção e evolução das paisagens sedimentares costeiras. As  variações do nível relativo do mar são identificadas através de indicadores geológicos, biológicos e arqueológicos. Objetiva-se identificar indicadores geológicos dessas variações na bacia hidrográfica do rio Una, região dos Lagos Fluminenses, Rio de Janeiro. Como procedimento metodológico elaborou-se seis perfis estratigráficos em diferentes pontos, envolvendo, análises sedimentológicas e faciológicos, combinadas, em todas as fases da pesquisa, a um controle sistemático de campo. Em laboratório elaborou-se tabelas de fácies sedimentares, contendo atributos referente a diagnose, cor, geometria, contato, estrutura sedimentar e conteúdo fossilífero. As idade obtidas ao radiocarbono variam entre 6330 a 4.800 cal anos A.P. Resultados sugerem que o processo sedimentar mais representativo em termos de conteúdo fossilífero foram deposições de conchas de moluscos no optimum climático holocênico, definido como periodo interglacial.
PROCESSOS FLUVIAIS E MORFOLOGIA EM CONFLUÊNCIAS DE CANAIS: UMA REVISÃO
Authors: Dos Santos Vanessa Cristina , Stevaux José Cândido
Published: April 2017

As confluências de canais constituem ambientes com alterações contínuas na estrutura de fluxo e no transporte de sedimentos. São locais na rede de drenagem em que se operam complexas interações entre matéria e energia, proporcionadas pela combinação de fluxos de padrões diferentes. Esta dinâmica peculiar pode influenciar desde aspectos ecológicos até questões de planejamento espacial e de ocupação do espaço. Nas últimas décadas, o interesse científico sobre os processos geomorfológicos ocorridos em confluências de canais tem aumentado. Este interesse deriva da crescente consciência de que os processos fluviais e a morfologia das confluências resumem as características da bacia hidrográfica a montante, ao mesmo tempo em que desempenham importante papel na regulação da circulação da água e sedimentos na rede de drenagem a jusante. Diversos estudos sobre os processos fluviais e morfologia em confluências de canais envolvem experiências laboratoriais, investigação de campo e simulações. Frequentemente estes estudos são uma combinação de diversas disciplinas como geomorfologia, ecologia, engenharia, hidrologia e sedimentologia, evidenciando o caráter multidisciplinar da análise desses ambientes complexos. No Brasil, os estudos sobre os processos geomorfológicos em confluências de canais são poucos, e em sua maioria desenvolvidas em rios de grande porte. Este artigo traz uma revisão e discussão sobre o estado atual do conhecimento sobre confluências de canais.
RIVER FUNCTIONING ANALYSIS FROM SUSPENDED SEDIMENT AND WATER DISCHARGE STUDY: THE CASE OF THE IVAÍ RIVER, SOUTHERN BRAZIL
Authors: Leli Isabel Terezinha , Stevaux José Cândido , Cremon Édipo Henrique , Da Nóbrega Maria Tereza
Published: April 2017

This paper presents the spatial distribution of liquid and solid (suspended load) discharge in the Ivaí River Basin, and its implication in the functioning of this river system. The Ivaí is a typical medium-size river of the basaltic plateau, the left side of the Paraná River Basin in southern Brazil. The data relating to water discharge and concentration of suspended sediment come from 19 gauging stations controlled by the former Superintendence of Water Resources and Environmental Sanitation Development – SUDERHSA, today Water Institute of Paraná. The river drains an area of 36,587 km2, and its average discharge during the study period (1974–2008) was 702.9 m3 s-1. The specific discharge (Qsp = Qm:Ab) varied uniformly between 0.01 and 0.02 m3 s-1 km2, however, an anomalous result of 0.11 m3 s-1 km2 was identified. Most of the water that enters the Ivaí River comes from the smaller sub-basins (< 500 km2), and the specific discharge from the tributaries decreases from upstream to downstream, from 0.028 to 0.015 m3 s-1 km-2. Correlations are high between the annual production of suspended sediment versus average discharge (R2 = 0.97) for all river gauging stations, and the contribution of suspended load versus basin area (R2 = 0.95). The water and suspended sediment discharge of the Ivaí River is similar to those dry-wet, temperate climate river in the world. A good correlation was also obtained when the river was compared with others plateau river in the world. The results make a great contribution to the management and planning projects for many basaltic-plateau rivers along the eastern side of the upper Paraná Basin, Brazil.
AVALIAÇÃO DA SUSCETIBILIDADE À RUTURA E PROPAGAÇÃO DE FLUXOS DE DETRITOS NA BACIA HIDROGRÁFICA DO RIO ZÊZERE (SERRA DA ESTRELA, PORTUGAL)
Authors: Melo Raquel , Zêzere José Luís
Published: April 2017

Na avaliação da suscetibilidade a movimentos de vertente, a cartografia produzida deverá integrar não só as áreas de iniciação do movimento, como também aquelas potencialmente atingidas pelo material mobilizado. Este objetivo é alcançado através da separação da análise da suscetibilidade em duas componentes distintas: (i) a primeira componente, que é também a mais explorada na literatura, corresponde à modelação das áreas de iniciação do movimento; (ii) a segunda componente refere-se à modelação das respetivas áreas de propagação, utilizando, como input, os mapas com a delimitação das potenciais áreas de rutura. Neste trabalho é feita a avaliação da suscetibilidade à ocorrência de fluxos de detritos na bacia hidrográfica do rio Zêzere (Serra da Estrela, Portugal). Para a identificação das potenciais áreas de rutura recorreu-se a um método estatístico bivariado (Valor Informativo) e a simulação das áreas afetadas pela passagem e deposição do material transportado foi sustentada por um algoritmo hidrológico simples (D-infinity downslope influence). A área abaixo da curva (AUC), determinada no âmbito da validação dos modelos de Valor Informativo, apresenta valores compreendidos entre 0,94 e 0,96, o que indica uma excelente capacidade preditiva. As variáveis preditivas com maior relevância na ocorrência de áreas de rutura de fluxos de detritos correspondem às áreas ardidas em 2005, declives superiores a 30°, espessura do solo inferior a 75 cm e perfil transversal côncavo. Na validação do modelo de propagação do material mobilizado, a partir das 36 áreas de rutura que constituem o inventário de movimentos, obteve-se uma taxa de verdadeiros positivos de 80,5%, o que reflete um bom desempenho do modelo.

Authors: Bashandy Alaa A. , Meleka Nageh N. , Hamad Mohamed M.
Published: April 2017

There are many factors, which may affect on concrete quality. One of those is concrete curing. Self-curing concrete is the solution. It may produce by using chemical curing agents. The concept of those agents is to reduce the water evaporation from concrete. This research aims to study the effect of chemical curing agents on the behavior of self-curing concrete. Two different chemical curing agents were used to study the main mechanical properties of concrete. The main variables are; the type of curing agent (Polyethylene glycol "PEG400"–Poly Acrylamide "PAM") and its dosages. The results obtained in terms of compressive, tensile and flexure strength values. Test results showed that the self-curing concrete cured by each agent performed better in hardened properties compared to none cured concrete. Also, curing using the both agents together perform better than using each one individually.
Effect of reinforcement in perforated brick arrangement for determining flexural strength and corrosion loss
Authors: Akter Mosfeka Mahabuba , Shahariar Atique , Islam Md. Shafiqul
Published: April 2017

Brick masonry walls consist of the main elements that responsible for the global stability of brick masonry buildings when subjected to lateral loads such as wind and seismic forces. These elements are subjected to gravity forces, bending moments and shear forces due to the horizontal loading. The application of reinforcement increases the deformation capacity, controls the crack opening and allows a better distribution of stresses. Longitudinal reinforcements increase the flexural strength, even if they seem not to influence the shear behavior. Effectiveness of reinforcement on the increase of the resistance of brick masonry wall is highly related to the failure mode of the element. This paper shows the flexural strength of reinforced perforated brick masonry wall and weight loss of reinforcements for corrosion after a certain period of time. Several reinforce bar arrangements into the perforated brick masonry walls show the variety of possible applications.

Published: April 2017

This paper presents an experimental and numerical investigation to determine the behavior of steel tubular columns filled with recycled aggregates concrete up to failure under constant axial compression loads. The experimental program included two steel tube columns, four recycled concrete columns and eight composite columns filled with different types of recycled coarse aggregates (granite and ceramic). Different percentages of recycled coarse aggregates: 0, 25 and 50 of the percentage of the coarse aggregates (dolomite) were used. The results of the numerical model that was employed by the finite element program, ANSYS, were compared with the experimental results. The results of the experimental study and the finite element analysis were compared with the design equations using different national building codes: AISC1999, AISC2005 and EC4. The results indicated that the recycled aggregates concrete inﬁll columns have slightly lower but comparable ultimate capacities compared with the specimens ﬁlled with normal concrete.

THIS ARTICLE HAS BEEN RETRACTED BY THE EDITORS AS ON APRIL 18, 2023. Child and adolescent psychotherapy has made great progress in recent years. With this progress, ethical issues have emerged that need to be addressed in the Indian setting. This article looks at various ethical issues in child and adolescent psychotherapy specific to Indian practitioners. The involvement of parents in psychotherapy often blurs therapeutic boundaries and issues related to confidentiality. Practitioners working in hospital and school settings are faced with similar problems. The advent of the internet and e-mail has resulted in new concerns for psychiatrists, related to communication via those media. Issues related to parenting, culture and development patterns, along with personal issues for the therapist, have been discussed.

Background: Studies employing next-generation sequencing (NGS) show that the oral fungal community (mycobiome) is far more complex than hitherto thought.  However, the role of the oral mycobiome in health and disease, including oral carcinogenesis, has not been explored. Objective: To characterize the mycobiome associated with oral squamous cell carcinoma (OSCC). Methods: Tissue biopsies [cases: 25 OSCC; controls: 27 intra-oral fibro-epithelial polyp (FEP)] were collected from oral and maxillofacial units in Sri Lanka. Total DNA was extracted and subjected to sequencing of the fungal ITS2 region using Illumina’s 2x300 bp chemistry. High quality, non-chimeric merged reads were classified to species level using a BLASTN-algorithm with UNITE’s named species sequences as reference. Downstream analyses were performed using QIIME and LEfSe. Results: 364 species representing 160 genera and 2 phyla (Ascomycota and Basidiomycota) were identified, with Candida and Malassezia making up 48% and 11% of the average mycobiome, respectively. However, only 5 species and 4 genera were detected in ≥50% of the samples. The species richness and diversity were significantly lower in OSCC. At the genus level, Candida, Hannaella and Gibberella were overrepresented in OSCC while Alternaria and Trametes were more abundant in FEP. Species-wise, C. albicans, C. etchellsii and Hannaella luteola-like species were enriched in OSCC while Malassezia restricta, Aspergillus tamarii, Alternaria alternate, Cladosporium halotolerans, and Hanseniaspora uvarum-like species were the most significantly abundant in FEP. Conclusions: A dysbiotic mycobiome dominated by C. albicans was found in association with OSCC. Whether this dysbiosis plays a role in oral carcinogenesis warrants further investigation.

Authors: Erol Volkan
Published: April 2017

Quantum Computers are provisioned as very high performance computers using quantum mechanical aspects for information processing. Quantum Information Theory and Quantum Computing topics are popular topics in academia aiming the construction of theoretical background of Quantum Computers. The information processing units for Quantum Computers are defined as qubits but for some problems three level (trinary) systems may be applied as well. We call these three level systems as qutrits. The scope of this work is the analysis of well-defined entanglement measures Negativity and Relative Entropy of Entanglement (REE) for two qutrit (3- level/trinary) quantum systems. In this manner, for randomly generated 1000 two qutrit and 1000 two qubit states the mentioned measures are calculated and these values are compared. These comparisons are analyzed and for quantum state ordering problem, some interesting results are reported.

We cultured Parmelina carporrhizans and P. quercina in Corn Meal Agar and 0.2% glucose Malt Yeast Agar for 160 days. Chemosyndrome of natural thalli and mycobiont cultures were analyzed by HPLC. Lecanoric acid, atranorin, chloratranorin and ergosterol were detected in P. carporrhizans thalli, while lecanoric acid, chloratranorin and aliphates were found in P. quercina thalli. The secondary methabolites pattern between thalli and mycobiont culture was completely different in both species. Both species secreted the phenalenone myeloconone C in culture media and was also detected in P. quercina mycobiont aggregates. Interestingly, the phenolic compounds produced by the mycobiont culture of P. carporrhizans are related to those produced by natural thallus by the same biosynthetic pathway, while the chemosyndrome of P. quercina mycobiont implies switch of biosynthetic pathway from acetate-polymalonate pathway to shikimic acid pathway, with pulvinic acid as major compound of mycobiont culture. The role of Myelochonone C, confluentic acid and pulvinic acid produced by mycobiont culture is discussed as possible adaptive vantage in field as photoprotective agent or as byproduct result of stressing artificial culture conditions.

Authors: Cutzu Raffaela , Bardi Laura
Published: April 2017

Alcoholic fermentations were performed adapting the technology to exploit the residual thermal energy (hot water at 83-85°C) of a cogeneration plant and to valorize agricultural wastes. Substrates were apple, kiwifruit and peaches wastes and Corn Threshing Residue (CTR). Saccharomyces bayanus was chosen as biocatalyst. The fruits, fresh or blanched, were mashed; CTR was gelatinized and liquefied by adding  Liquozyme® SC DS (Novozyme); saccharification simultaneous to fermentation was carried out using the enzyme Spirizyme® Ultra (Novozyme). Lab-scale static fermentations were carried out at 28°C and 35°C, using raw fruits, blanched fruits and CTR, monitoring the ethanol production. The highest ethanol production was reached with CTR (10,22%9 and among fruits with apple (8,71%). Distillations at low temperatures and under vacuum, to exploit warm water from cogeneration plant, were tested; distillation at 80°C and 200 mbar or 400 mbar allowed to recover 93,35 and 89,59 % of ethanol respectively. These results support a fermentation process coupled to a cogeneration plant, fed with apple wastes and with CTR when apple wastes are not available, where hot water from cogeneration plant is used in blanching and distillation phases. The scale up in a pilot plant was also carried out.
Fasudil Attenuates LPS-Induced Acute Lung Injury by Preventing Endothelial Dysfunction

Fasudil, a potent Rho kinase (ROCK) inhibitor, can ameliorate LPS-induced acute lung injury (ALI) in mice, but the mechanism remains obscure. In this study, a mice model of ALI was established by intra-tracheal instillation of LPS. Histological changes, cytokine levels, lung permeability, and endothelial apoptosis were determined to evaluate the effects of fasudil on lung injury. The cellular and molecular biological mechanisms were explored by culturing human pulmonary microvascular endothelial cells (PMECs). The results showed that fasudil reduced LPS-induced lung inflammation, pulmonary hyperpermeability, and endothelial apoptosis in mice. In cultured human PMECs, fasudil inhibited LPS-induced caspse-3 cleavage and cell apoptosis. It also decreased LPS-induced hyperpermeability of human PMECs monolayer by reversing the down-regulation of intercellular junctions. Moreover, fasudil inhibited LPS-induced overexpression of chemokines and intercellular adhesion molecule (ICAM)-1 in human PMECs, which in turn suppressed neutrophil chemotaxis and neutrophil-endothelial adhesion. Further molecular researches showed fasudil inhibited LPS-induced activation of ROCK, NF-κB, and p38 in human PMECs. Our findings demonstrated that fasudil alleviated LPS-induced ALI by protecting endothelial function via inhibiting endothelial apoptosis, maintaining endothelial barrier integrity, and reducing endothelial inflammation. These effects of fasudil could be attributed to the inhibition of ROCK and its downstream NF-κB and p38 signaling pathways.

Published: April 2017

Detailed information about graft material characteristic is crucial to evaluate their clinical outcomes. The present study evaluates the physicochemical characteristics of two xenografts manufactured on an industrial scale deproteinized at different temperatures (non-sintered and sintered) in accordance with a protocol previously used in sinus lift procedures. It compares how the physico-chemical properties influence the material performance in vivo with a histomorphometric study in retrieved bone biopsies following maxillary sinus augmentation, in 10 clinical cases. X-ray diffraction analysis revealed typical structure of hydroxyapatite for both materials. Both xenografts are porous and exhibit intraparticle pores. Strong differences were observed in terms of porosity, cristallinity, and calcium/phosphate. Histomorphometric measurements on the bone biopsies showed statistically significant differences. The physicochemical assessment of both xenografts in accordance with the protocol developed at industrial scale confirmed that these products present excelent biocompatibilitity, with characteristics similar to natural bone. The sintered HAs xenograft exhibit higher osteoconductivity although were not complete resorbable (30.80±0.88% residual material). On the other hand, the non-sintered HAs xerograft induced about 25.92±1.61% of new bone and almost complete degradation after 6 months implantation. Differences in physico-chemical characteristics found between the two HAs xenograft determine different behavior of this material.
New Link between Skin Microbiota Diversity and Skin Health: Proposal to Use This as a Mechanism to Determine Whether Cosmetic Products Damage the Skin and Are a Cause of the Skin Allergy Epidemic
Authors: Wallen-Russell Christopher , Wallen-Russell Sam
Published: April 2017

There is a skin allergy epidemic in the western world, and the rate of deterioration has increased significantly in the past 5-10 years. It is probable that there are many environmental contributing factors, yet some studies have linked it primarily to the rise in the use of synthetic chemical ingredients in modern cosmetics. Our challenge, therefore, was to find a mechanism to determine the effect these substances have on skin health, and whether they really are a primary cause of long term damage to the skin. The first problem is the lack of any definitive way to measure skin health. Motivated by the overwhelming evidence for a link between deficient gut flora and ill health, we decided to look at whether our skin microbiota could similarly be used as an indicator of skin health. Our research illustrates how it is microbiota diversity alone that can predict whether skin is healthy or not, after we revealed a complete lack of conclusive findings linking the presence or abundance of particular species of microbe to skin problems. This phenomenon is replicated throughout nature, where high biodiversity always leads to healthy ecosystems. ‘Caveman’ skin, untouched by modern civilisation, was far different to ‘western’ skin and displayed unprecedented levels of bacterial diversity. The less exposed communities were to western practices, the higher the skin diversity, which is clear evidence of an environmental factor in the developed world damaging skin. For the first time we propose benchmark values of diversity against which we can measure skin to determine how healthy it is. This gives us the ability to be able to predict which people are more likely to be prone to skin ailments, and start to test whether cosmetic ingredients and products are a main cause of the skin allergy epidemic.
