Fipronil é um pesticida fenilpirazólico amplamente utilizado como defensivo agrícola nas culturas de cana-de açucar contra insetos-praga. O objetivo deste trabalho foi avaliar a toxicidade aguda do agrotóxico fipronil à biota de água doce, utilizando os rotíferos Asplanchna sieboldi, Brachionus caudatus e Lepadella patella como organismos-teste. Estes rotíferos foram obtidos de amostras de plâncton da Represa de Guarapiranga, situada em São Paulo, SP. Os testes de toxicidade foram realizados utilizando-se o produto comercial Regente 800 WG ® cujo princípio ativo é o fipronil. Para A. sieboldi as concentrações testadas foram: 1,56, 3,12, 6,25 e 12,5 mg L-1, para B. caudatus e L. patella 12,5, 25, 50 e 100 mg L-1. Os valores obtidos para a CL50 - 48h de fipronil foram: 10,65 mg L-1 para A. sieboldi e de 39,69 mg L-1 para B. caudatus. O rotífero L. patella não sobreviveu em nenhuma das concentrações testadas. Comparando-se as espécies, concluiu-se que L. patella foi a mais sensível ao fipronil e que A. sieboldi é menos sensível que B. caudatus. O importante papel que os rotíferos desempenham na comunidade zooplanctônica dos corpos de água tropicais tornam imprescindíveis a realização de estudos que abordem aspectos biológicos e ecotoxicológicos em seus ciclos de vida, os quais são ainda incipientes. O fato das espécies estudadas apresentarem alta sensibilidade, além de possuirem elevada taxa reprodutiva e curta longevidade, sugere que espécies deste grupo poderão ser uma ferramenta importante como organismos-teste na avaliação da toxicidade deste e de outros agrotóxicos, visando a obtenção de subsídios para ações voltadas à preservação da diversidade da biota aquática.

TOXICIDADE AGUDA DO AGROTÓXICO CARBOFURANO AO CLADÓCERO CERIODAPHNIA SILVESTRII DADAY, 1902
Authors: Da Silva Mansano Adrislaine , Aparecida Moreira Raquel , Rocha Odete 
Published: February 2015

RESUMO: Nos últimos anos o aumento do consumo de agrotóxicos em todo o mundo tem preocupado agências nacionais e internacionais em decorrência dos diversos impactos ambientais e das sérias implicações à saúde humana. Dentre os agrotóxicos, o carbofurano é utilizado amplamente no Brasil em culturas de batata, milho, amendoim, arroz e soja. Como existe o risco deste composto ser carreado por diversos mecanismos até os corpos d’água e causar toxicidade a espécies não-alvo, é necessária a avaliação dos seus efeitos nestes ecossistemas. O objetivo deste trabalho foi avaliar a toxicidade aguda do carbofurano sobre a espécie nativa tropical Ceriodaphnia silvestrii. Para isso, realizaram-se testes de toxicidade aguda, com concentrações nominais deste agrotóxico. Para o dafinídeo C. silvestrii, os valores de CE50 24 h e CE50 48 h foram de 1,80 µg L-1 e 0,75 µg L-1, respectivamente. Os resultados obtidos mostraram que C. silvestrii apresentou elevada sensibilidade ao agrotóxico carbofurano e foi mais sensível do que as espécies de cladóceros de regiões temperadas, de acordo com os dados da literatura. Considerando-se estes resultados e da ampla distribuição de C. silvestrii em regiões tropicais e subtropicais, sugere-se o uso desta espécie em avaliações ecotoxicológicas com agrotóxicos em águas doces tropicais.

Published: February 2015

O Pequeno produtor de leite bovino tem grande dificuldade em adequar sua produção aos parâmetros da Instrução Normativa no. 51 pela necessidade de alto investimento em equipamentos de aquecimento de água que deve ser utilizada na rotina higiênica da produção. A qualidade do leite é definida por fatores relativos ao manejo dos animais (sanidade e alimentação) e práticas de higiene antes, durante e depois da ordenha. Parte desse processo de higiene é realizada com água de qualidade boa em temperatura fria e quente (50 – 60ºC) aquecida por energia usual (elétrica e gás GLP), para limpeza dos aparelhos e utensílios utilizados na ordenha, o que interfere nos resultados financeiros do produtor. O presente trabalho preocupou-se em utilizar uma proposta de aquecimento da água através da implantação de sistemas híbridos de aquecedores (elétrico-solar, elétrico-gás ou solar-gás) na unidade produtiva. Foram utilizadas análises microbiológicas em amostras de leite coletados após a lavagem dos utensílios de ordenha manual ser realizada utilizando água aquecida pelos sistemas apresentados. Os resultados das análises laboratoriais apresentaram considerável redução no NMP/mL de leite para Coliformes a 35 ºC para as amostras não pasteurizadas colhidas após a realização das lavagens dos materiais de ordenha manual ser realizada utilizando água aquecida pelo sistema híbrido composto pelo aquecedor solar e pelo aquecedor a gás. Este tipo de sistema de aquecimento de água permite aos pequenos produtores de leite adequarem-se a IN 51, com baixo custo de investimento principalmente em localidades desprovidas de fornecimento de energia elétrica.

O uso da terra é de fundamental importância quando se pensa o espaço agrário. Assim, esse trabalho, sob o ponto de vista ambiental, se debruça sobre as atividades que são desenvolvidas em torno da barragem Cajarana, Distrito de São Pedro, Garanhuns – PE e fazem refletir acerca da consciência ambiental da comunidade que lá vive e pratica a agropecuária. O objetivo principal desse trabalho é oferecer elementos que sirvam a reflexão da situação atual do referido espaço. A metodologia utilizada pautou-se em pesquisa bibliográfica sobre tópicos como uso da terra, agrotóxicos, geografia agrária, geografia de Pernambuco, além de um reconhecimento de campo onde se usou como recurso adicional a fotografia para registro de elementos da paisagem. Os resultados são apresentados em caráter descritivo e reflexivo, contextualizados no tempo e no espaço, de forma a gerar um quadro representativo do que se percebeu como falta de conhecimento com o ambiente e sustentabilidade das atividades desenvolvidas, basicamente agricultura de subsistência mas que se torna mais grave pela implantação recente de plantios de tomate, os quais requerem o uso de agrotóxicos usados sem nenhum critério em relação ao ambiente, em especial tornando-se um gerador de poluição para as águas da barragem Cajarana.

Published: February 2015

Background: The use of Morse taper systems in dental implantology has been associated widely with a more precise adaptation between implants and their respective abutments. This may lead to an increase in the stability of the implant system and may also prevent microbial invasion through the implant–abutment interface. The aim of this study was to investigate in vitro the ability of four commercially available Morse taper system units to impede bacterial penetration through their implant–abutment interfaces.Methods: Abutments were screwed onto the implants, and the units were subsequently immersed in Streptococcus sanguinis bacterial broth (1 × 108 colony forming units/mL) for 48 hours. The units were examined by scanning electron microscopy (SEM) under three conditions: 1) with the implant–abutment components assembled as units to investigate for both the existence of microgaps and the presence of bacteria; 2) with the implants and abutments separated for examination of internal surfaces; and 3) with the implant–abutment components again assembled as units to measure any microgaps detected. The mean size of the microgaps in each unit was determined by measuring, under SEM, their width in four equidistant points.Results: Microgaps were detected in all units with no significant differences in dimension (Kruskal‐Wallis test, P >0.05). Within all units, the presence of bacteria was also observed.Conclusion: The seals provided by the interfaces of the commercially available Morse taper implant–abutment units tested were not sufficiently small to shield the implant from bacterial penetration.

Objectives/Scope:
1. Outline challenges O&G Big data brings and emerging requirements 2. Propose alternative approach for Big Data processing at the remote sites and why Cloud is not enough 3. Demonstrate O&G use cases that benefit from the proposition Methods, Procedures, Process: Fog computing is a new and growing technology area designed to address requirements for processing at the edge of growing amounts of field data (O&G Internet of Things), and to address new applications that have low-latency requirements and can not be addressed by cloud infrastructure typical for other industries. Fog is not a replacement of the cloud, but an extension. It allows O&G companies to extend analytics, expand context awareness, improve data quality at the remote site (Oilfield, Offshore Drilling/Production Platform) Results, Observations, Conclusions: Key areas and emerging O&G application that benefit from Fog phenomena, and currently piloted by O&G majors and automation & instrumentation suppliers: • Real-time actionable analytics • Real-time data sharing between different applications, vendors and service providers • Wellhead optimisation • Fleet mobility and management • Leak detection and distributed safety systems • Employee safety • De-manning and automation • Secure, federated data ownership The technology fundamentally fits so well into the O&G industry as its operations are taking place in remote geographies, and there is a clear need for effective combined local and remote data processing, especially triggered by growing volumes of data at the edge. As an example, Distributed Acoustic Sensor for Vertical Flow Profiling use case is capable to generate around 1-2 TB of data per day per well. However, typical satellite channel to the data centre is around 250K-1Mb. Fog Computing enables pre-processing of the data and distributed analytics at the edge, thus optimising data transmission, however allowing geo scientist still to inquire high resolution data from remote site, in case there is an interest to zoom into particular area. Novel/Additive Information: Fog Computing is a new and revolutionising phenomena for field remote processing of data at scale. It is going through pilot stage, and O&G companies are loading it with multitude of use case and applications to explore full potential and develop competitive advantage with more agile platform for data insights and knowledge.

ABSTRACTJatropha curcas L. has been promoted as a “miracle” tree in many parts of the world, but recent studies have indicated very low levels of genetic diversity in various landraces. In this study, the genetic diversity of landrace collections of J. curcas was compared with the genetic diversity of the species from its native range, and the mating system was analyzed on the basis of microsatellite markers. The genetic diversity parameters were estimated, and analysis of molecular variance, principal coordinate analysis, and unrooted neighbor‐joining tree were used to describe the relationship among populations. Results confirmed very low genetic diversity in African and Asian landraces. Mexican populations from the regions of Veracruz, Puebla, and Morelos were also found to have low levels of diversity (mostly monomorphic), while populations from Chiapas were polymorphic with an expected heterozygosity between 0.34 and 0.54. Bayesian analysis showed differentiation according to geographic locations, which was confirmed by principal coordinate analysis and neighbor‐joining tree. Estimations of outcrossing rate of individual families from Chiapas showed that some mother trees were mainly outcrossing. Mating system could not be estimated in the landraces from Mali and populations from Veracruz, Puebla, and Morelos (Mexico), as these were highly monomorphic. The observed low level of genetic diversity in some of the populations and landraces suggests that breeding programs should test for genetic variation and heritability in relevant quantitative traits and estimate if sufficient gain can be expected from traditional testing and selection. Diversification of the local gene pools may be considered for breeding and selection.

Authors: Kung A.Y.H , Zhang S , Zheng L.W , Wong G.H.M , Chu C.H 
Published: February 2015

Aim:
To study the oral health status of Chinese children and adolescents undergoing chemotherapy in Hong Kong.

Method: All Chinese children and adolescent oncology patients aged 18 or below attending the Children's Centre for Cancer and Blood Disease at a hospital for chemotherapy were invited and parental consent was sought before they were accepted into the study. The study comprised of 1) a parental questionnaire, 2) the collection of medical history and 3) a clinical examination for tooth decay (caries) and mucosal status.

Results:
A total of 69 patients were invited, and they all participated in this study. Their mean age was 9.2±5.0 and 44 (64%) were males. Twenty-six patients (38%) had no caries experience (DMFT and/or dmft = 0). Higher caries experience was detected in participants that were not born in Hong Kong, had completed active chemotherapy, participated in school dental care service and whose parents had low educational levels. There were 41 patients with active chemotherapy, 24 of whom were diagnosed with acute leukaemia, 5 with haematological malignancies other than leukaemia and 11 with solid tumours. Antimetabolites, cytotoxic antibiotics, alkylating agents and plant alkaloids were administered in 49%, 32%, 24% and 22% of them, respectively. Twenty-six (63%) patients showed no mucosal complications. The most common oral complication was oral mucositis (24%) followed by petechiae (10%).

Conclusion:
About two-thirds of paediatric and adolescent cancer patients had caries experience, which was more common among those who had completed chemotherapy. Oral mucositis followed by petechiae were the two most common complications of receiving chemotherapy.

Authors: Mikláš R. , Miklášová N. , Bukovský M. , Devínsky F. 
Published: February 2015

Abstract
A group of homochiral imidazolium salts bearing hydrophobic camphor derived moiety and ester or amide functional group were synthesized and characterized. The novel imidazolium bromides were tested as antimicrobial and antifungal agents and their minimal inhibitory concentration (MIC) was evaluated and compared to clinically used benzalkonium bromide (BAB) and carbethopendecinium bromide. The MIC values of amide derivatives 2a and 2b were slightly smaller than those for BAB, indicating their good activity. None of the prepared salts was more effective than carbethopendecinium bromide. The biocidal efficacy of amide derivatives was much higher compared to the ester analogues.

Abstract
The objective of this study was to analyze the effect of supplementation with creatine and glutamine on physical fitness of military police officers. Therefore, an experimental double blind study was developed, with the final sample composed by 32 men randomly distributed into three groups: a group supplemented with creatine (n=10), glutamine (n=10) and a placebo group (n=12) and evaluated in three distinct moments, in an interval of three months (T1, T2 and T3). The physical training had a weekly frequency of 5 sessions x 90 min, including strength exercises, local muscular resistance, flexibility and both aerobic and anaerobic capacity. After analyzing the effect of time, group and interaction (group x time) for measures that indicated the physical capabilities of the subjects, a significant effect of time for the entire variable was identified (p<0,05). However, these differences were not observed when the univaried intragroups and intergroups analysis was performed (p>0,05). In face of the results it was concluded that supplementation with creatine and glutamine showed no ergogenic effect on physical performance in military police officers.

Abstract
The object of the study was to analyze the relationship between aerobic fitness and body composition in postmenopausal women. We hypothesized that postmenopausal women that had higher adiposity had lower cardiorespiratory capacity, regardless of the characteristics of menopause. The sample included 208 women (57.57 ± 6.62 years), whose body composition and the basal metabolic rate were evaluated by octopolar bioimpedance (InBody 720) and the oxygen uptake by the modified Bruce protocol. Most of the sample showed obesity and a high visceral fat area. The visceral fat area and the basal metabolic rate explained 30% of the variation of oxygen uptake, regardless of age, time, nature or hormone therapy. The values of the latter variables were reduced in the presence of high central adiposity (-6.16 ml/kg/min) and the basal metabolic rate of less than 1238 kcal/day (-0.18 ml/kg/min). The women with oxygen uptake above 30.94 ml/kg/min showed lower values of total and central adiposity when compared with other groups. With an increase of aerobic fitness, there was a growing tendency of the average values of the soft lean mass index, with differences between the groups low-high and moderate-high. These results suggest worsening of the cardiorespiratory condition with an increase of central adiposity and a decrease of the BMR, regardless of age and menopause characteristics.

Published: February 2015

Abstract
The enforced sedentary lifestyle and muscle paresis below the level of injury are associated with adipose tissue accumulation in the trunk. The value of anthropometric indicators of obesity in patients with spinal cord injuries has also been called into question. We hypothesized that the Body Mass Index recommended by the WHO to diagnose obesity in general population has too low sensitivity in case of wheelchair rugby players.
The study group comprised 14 wheelchair rugby players, aged 32.6 ± 5.1 years, who had sustained CSCI (paralysis of lower limbs and upper extremities). The research tool was the Tanita Viscan visceral and trunk fat analyzer AB140 using the abdominal bioelectrical impedance analysis (BIA) to estimate the visceral fat level (Vfat) and trunk fat percentage (Tfat). The AB140 analyzer also allowed the measurement of body composition of those individuals who could not assume an upright position. Our analyses revealed high and very high correlation coefficients between Vfat and WC (r=0.9), WHtR (r=0.7) and Tfat (r=0.9) whereas the correlation between Vfat and the BMI was weak, especially in the subgroup with Vfat < 13.5% ( r=0.2). The subgroup with Vfat>13.5 exhibited a moderate-level relationship between the BMI and visceral fat increase. It was concluded that the BMI had a low sensitivity for predicting obesity risk in wheelchair rugby players after CSCI. The sensitivity of WC measurement was higher and thus, it may be stated that it constitutes an objective tool for predicting obesity risk in post-CSCI wheelchair rugby players.
