Combination prevention efforts are now recommended toward reducing HIV incidence among men who have sex with men (MSM). Understanding the perceptions of both MSM and service providers is critical to informing the development of prevention packages and ultimately improving intervention effectiveness. This study assessed the preferences of MSM and health service providers in the administration of HIV-prevention efforts. Qualitative data were gathered from a series of separate MSM and health care provider focus groups in 2 South African cities. Participants discussed HIV-prevention services and MSM client experiences within South Africa and identified the 3 most important clinic characteristics and 3 most important HIV-prevention services for MSM clients. Priorities indicated by both MSM and health care providers were confidentiality of visit, friendly staff, and condoms, while discrepancies existed between MSM and providers regarding provider consistency and the provision of pre-exposure prophylaxis/post-exposure prophylaxis (PrEP/PEP) and lubricant as prevention methods. Effective interventions must address these discrepancies through the design of intervention and provider training to optimally accommodate MSM.

Background: There are no publicly available tools designed specifically to assist policy makers to make informed decisions about the optimal ages of breast cancer screening initiation for different populations of US women. Objective: To use three established simulation models to develop a web-based tool called Mammo OUTPuT. Methods: The simulation models use the 1970 US birth cohort and common parameters for incidence, digital screening performance, and treatment effects. Outcomes include breast cancers diagnosed, breast cancer deaths averted, breast cancer mortality reduction, false-positive mammograms, benign biopsies, and overdiagnosis. The Mammo OUTPuT tool displays these outcomes for combinations of age at screening initiation (every year from 40 to 49), annual versus biennial interval, lifetime versus 10-year horizon, and breast density, compared to waiting to start biennial screening at age 50 and continuing to 74. The tool was piloted by decision makers (n = 16) who completed surveys. Results: The tool demonstrates that benefits in the 40s increase linearly with earlier initiation age, without a specific threshold age. Likewise, the harms of screening increase monotonically with earlier ages of initiation in the 40s. The tool also shows users how the balance of benefits and harms varies with breast density. Surveys revealed that 100% of users (16/16) liked the appearance of the site; 94% (15/16) found the tool helpful; and 94% (15/16) would recommend the tool to a colleague. Conclusions: This tool synthesizes a representative subset of the most current CISNET (Cancer Intervention and Surveillance Modeling Network) simulation model outcomes to provide policy makers with quantitative data on the benefits and harms of screening women in the 40s. Ultimate decisions will depend on program goals, the population served, and informed judgments about the weight of benefits and harms.

N2O strongly prevents adhesion formation and postoperative pain in open surgery through a drug-like effect
Authors: Corona Roberta , Binda Maria Mercedes , Adamyan Leila , Gomel Victor , Koninckx Philippe R.
Published: November 2017

Background

Microsurgical tenets and peritoneal conditioning during laparoscopic surgery (LS) decrease postoperative adhesions and pain. For a trial in human, the strong beneficial effects of N2O needed to be confirmed in open surgery (OS).

Results

In a mouse model for OS, the effect of the gas environment upon adhesions was evaluated. Experiment I evaluated desiccation and the duration of exposure to CO2, N2O or CO2 + 4%O2. Experiment II evaluated the dose-response curve of adding N2O to CO2. Experiment III compared humidified CO2 + 10% N2O during LS and OS.

In OS, 30- and 60-min exposure to non-humidified CO2 caused mortality of 33 and 100%, respectively. Mortality was prevented by humidification, by dry N2O or dry CO2 + 4%O2. Adhesions increased with the duration of exposure to CO2 (p < 0.0001) and decreased slightly by humidification or by the addition of 4% O2. N2O strongly decreased adhesions at concentrations of 5% or greater. With humidified CO2 + 10% N2O, adhesion formation was similar in OS and LS.

Conclusions

The drug-like and strong beneficial effect of low concentrations of N2O is confirmed in OS.

Open Science, Bandung and Ezekiel: crafting a transnational knowledge space towards the brave new world
Authors: Wong Pak Nung
Published: November 2017

To explore a new de-colonial option for the global future, this article grapples with three movements of our time: the ‘Open Science’ movement, the 1955 African-Asian conference and the Non-Aligned Movement, and the post-exilic prophetic movement of the Abrahamic religions. It explores an alternative intellectual project which will facilitate new research agendas and publication directions that will simultaneously speaks to the three wider audience of the present-day world: the sciences, the Global South and the Abrahamic religious traditions. My objective is to delineate a theological, geopolitical and anthropological exposition as an ethical anchorage for the present Bandung project to steadily move towards the Open Science era. I will argue for Ezekiel’s prophetic model as a plausible de-colonial option for crafting the transnational open knowledge space.
Relationship between the Conductivities of CeO2-ZrO2-MOx (M = Bi, Ca, Sn, Ni, Fe) Solid Solutions and Catalytic Activities during Methane Oxidation
Authors: Jeong Minchan , Nunotani Naoyoshi , Imanaka Nobuhito
Published: November 2017

We investigated the relationship between the conductivities of CeO2-ZrO2-MOx (M = Bi, Ca, Sn, Ni, Fe) solid solutions and the catalytic abilities of catalysts composed of PdO on CeO2-ZrO2-MOx/γ-Al2O3 supports. The oxide-ionic conductivities of the CeO2-ZrO2-MOx promoters increased with increasing oxygen vacancy concentrations and the electronic conductivities of these promoters were significantly enhanced by doping with Sn4+/2+, Ni3+/2+ and Fe3+/2+, all of which readily undergo valency changes. Studies of the oxygen release characteristics of CeO2-ZrO2-MOx/γ-Al2O3 samples found that the reduction temperatures obtained from hydrogen temperature programmed reduction data were primarily determined by the electronic conductivity of the promoter rather than by the oxide-ionic conductivity. However, the oxygen storage capacity of each CeO2-ZrO2-MOx/γ-Al2O3 sample was related to both the oxide-ionic and electronic conductivities. The catalytic methane oxidation activities of these materials were evidently affected by both the reduction temperature and the oxygen storage capacity. As a result, the activities of the PdO/CeO2-ZrO2-MOx/γ-Al2O3 catalysts were clearly dependent on the oxide-ionic and electronic conductivities of the CeO2-ZrO2-MOx promoters.

Published: November 2017

Crystals consisting of the closed-ring form of 1,2-bis(3-methyl-5-phenyl-2-thienyl)perfluorocyclopentene underwent a photochemical ring-opening reaction accompanying crystal fragmentation upon irradiation with visible light. The open-ring form crystal produced by the ring-opening reaction exhibited green fluorescence, whereas open-ring form crystals produced by recrystallization exhibit orange or yellow fluorescence depending on the polymorphic forms. The fluorescence quantum yield of the photogenerated open-ring form crystal was larger than that in n-hexane. The open-ring form exhibits different fluorescence colors depending on the intermolecular interaction in different states.

Published: November 2017

With the increasing numbers of Facebook fan-page users, finding information based on their interests has become difficult, and fan-page managers are challenged as they try to understand the needs of these users. To understand their needs and preferences and increase the effectiveness of fan-page marketing, we use two-step clustering to group 42,953 Facebook fan-page users. The results of our study show seven clusters, each with different key characteristics. We label them as lurk, informational, health and beauty, visual lady, intellectual reader, consumption and shopping, and highly active fans. One of our objectives in this paper is to help fan-page managers use our results to target users and to draft management strategies.
Mobile Money in Tanzania
Authors: Economides Nicholas , Jeziorski Przemyslaw
Published: November 2017

In developing countries, mobile telecom networks have emerged as major providers of financial services, bypassing the sparse retail networks of traditional banks. We analyze a large individual-level data set of mobile money transactions in Tanzania to provide evidence of the impact of mobile money on alleviating financial exclusion in developing countries. We identify three types of transactions: (i) money transfers to others, (ii) short-distance money self-transportation, and (iii) money storage for short to medium periods of time. We utilize a natural experiment of an unanticipated increase in transaction fees to identify the demand for these transactions. Using the demand estimates, we find that the willingness to pay to avoid walking with cash an extra kilometer (short-distance self-transportation) and to avoid storing money at home (money storage) for an extra day are 1.25% and 0.8% of an average transaction, respectively, which demonstrates that mobile money ameliorates significant amounts of crime-related risk. We explore the implications of these estimates for pricing and demonstrate the profitability of incentive-compatible price discrimination based on type of service, consumer location, and distance between transaction origin and destination. We show that differential pricing based on the features of a transaction delivers a Pareto improvement.

Workload-Dependent Dynamic Priority for the Multiclass Queue with Reneging
Authors: Atar Rami , Lev-Ari Anat
Published: November 2017

Scheduling control for a single-server queue with I customer classes and reneging is considered, with linear holding or reneging cost. An asymptotically optimal (AO) policy in heavy traffic is identified where classes are prioritized according to a workload-dependent dynamic index rule. Denote by ci, μi, and θi, i ∈ ℐ := {1, …, I} the queue length cost, service rate, and reneging rate, for class-i customers. Then, a relabeling of the classes and a partition 0 = w0 < w1 < ⋯ < wK = ∞, K ≤ I are identified such that the policy acts to always assign least priority to the class i when the rescaled workload is in the interval [wi−1, wi). The relabeling is such that when workload is withing the lowest [resp., highest] interval [wi−1, wi), the least priority class is the one with smallest cμ [resp., greatest θ] value. This result stands in sharp contrast to known fluid-scale results where it is AO to prioritize by the fixed cμ/θ index. One of the technical challenges is the discontinuity of the limiting queue length process under optimality. Discontinuities occur whenever the workload reaches one of the levels wi.
An alternative to RCTs in the case of sample heterogeneity
Authors: Fredericks Suzanne , Lapum Jennifer , Policelli Julia
Published: November 2017

As the population living with congenital heart disease ages, health promotion interventions have become more important. The uptake and maintenance of health-promoting behaviours and social support for the congenital heart disease population not only have the potential to extend a person's life expectancy, but also enhance quality of life and overall health and wellbeing. Using a gold-standard approach, such as a randomised controlled trial (RCT), to evaluate the effectiveness of such an intervention does not address heterogeneity among individuals, while the results obtained from RCTs tend to not be generalised to the larger population of interest. The Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework provides an alternative evaluative approach to examining the effectiveness of online gaming interventions, and has the capacity to address the unique needs of the congenital heart disease population.

New outcome measures in perioperative care
Authors: Salih Tom , Lau Hoon Ying , Moonesinghe S Ramani
Published: November 2017

Improvements in outcome measurement are needed to produce quality improvement in perioperative care. However, problems with the collection and use of outcome data persist in research and clinical practice. This is being addressed by several national programmes and initiatives to standardize and integrate outcome measurement.

The use of different outcome measures is changing and there has been a transition towards patient-focused measures. Traditional measures of quality in perioperative care include mortality, morbidity and resource utilization measures. Patient-focused measures include patient-reported outcome measures and measures of patient experience. Each of these has advantages and disadvantages in different situations.

The routine collection, analysis and dissemination of data relating to perioperative outcome is beneficial to patients, clinicians, hospitals, commissioners, regulators and researchers.
Case report: using botulinum toxin type A in a patient with a history of depression
Authors: Millar-Hume Lucy
Published: November 2017

Consulting patients with a history of mental ill-health spans across every medical field, including aesthetics. Many people suffer from depression, transiently or chronically, throughout their lives. Depression can impair individuals' day-to-day functioning or affect the way they feel about their outward appearance. More often people with depression can lose interest in their appearance, but this is not always the case. Patients may also present with other mental health problems, such as body dysmorphic disorder (BDD). With time and experience, aesthetic practitioners can grow to understand, identify, consent and treat individuals who suffer from depression and mental ill-health without doing them harm. BDD, however, should remain a contraindication to treatment with botulinum toxin type A.

Published: November 2017

Este trabalho teve por objetivo identificar as principais características de um modelo de cluster comercial localizado no bairro do Brás, município de São Paulo (SP), e caracterizar os diferentes segmentos da área têxtil na região. Região economicamente importante, o bairro do Brás possui uma forte atratividade para clusters comerciais, destacando-se, entre seus atrativos, o fluxo contínuo de pessoas e o elevado número de comércios. O estudo, de natureza descritiva, tem como base o modelo proposto por Zaccarelli et al. e busca identificar a formação do cluster e a presença de um agente supraempresa (governança supraempresarial). Um questionário com questões relativas aos fatores que influenciam a permanência dos comerciantes no agrupamento foi respondido por quarenta lojistas da região. Receberam destaque nas respostas aos questionários os seguintes fatores: equilíbrio entre comércios (ausência de posições privilegiadas), complementaridade por utilização de subprodutos, cooperação entre empresas e cultura da comunidade adaptada ao cluster. Outros fundamentos, contudo, demonstraram-se pouco valorizados: caráter evolucionário por introdução de tecnologias e estratégia de resultado orientada para o cluster. As vantagens competitivas percebidas a partir dos fundamentos propostos por Zaccarelli et al. caracterizam a região estudada como um cluster comercial com traços de desenvolvimento e competitividade. Palavras-chave: Cluster comercial; segmento têxtil; características comerciais locais.

Nota-se principalmente que os indicadores sociais internos apresentam uma relação direta e significativa com os resultados organizacionais, indicando que investir nos funcionários tende a produzir resultados financeiros positivos para as empresas.
Hosting the lament(s) of Others? Tensions and antinomies in Dries Verhoeven’s No Man’s Land
Authors: Chatziprokopiou Marios
Published: November 2017

No Man’s Land was a peripatetic performance produced in Athens by the Onassis Cultural Center (2014) and previously presented in several European cities. According to its director Dries Verhoeven, the piece sought to explore ‘what is a multicultural environment today’ by staging one-to-one encounters, where (ostensibly local) spectators were guided by performers (migrants, refugees or asylum seekers) through the city while listening to a story of forced displacement and exile. Drawing on a corpus of semi-structured interviews with the Athens-based performers, this article examines the performers’ own conceptions and experiences of this institutional attempt to ‘host’ the laments of Others, as ‘both a performance and a political act’ (Anon. 2014b). Participants’ narratives are studied in connection to the representational strategies of the performance, in an attempt to unpack interrelations between these theatrical walks and everyday experiences of discrimination in the Athenian urban fabric. In doing so, the article reveals a larger field of tensions and antinomies between representations and presences, vocalizations and silences, languages of the Other and mother tongues, art and ‘life’.

Consideraciones sobre el cambio de percepción de Raúl Prebisch en el entendimiento del rol del Estado para el desarrollo latinoamericano (1949–1963).
Authors: Ormaechea Emilia , Fernández Víctor Ramiro
Published: November 2017

El artículo analiza el modo en cómo Raúl Prebisch entendió el rol del Estado en su propuesta de desarrollo durante el período en que ejerció la Secretaría Ejecutiva de la CEPAL (1949–1963). Al focalizar el análisis en el Estado, es posible advertir que las referencias de Prebisch hacia el mismo han ido cambiando a lo largo de su producción teórica, pudiéndose identificar un punto de inflexión en el año 1955. De esta manera, se diferencia un primer momento de invocación activa al Estado, donde predomina una concepción normativa sobre su rol para el desarrollo, y un segundo momento en el cual se hace visible una postura más crítica por parte de Prebisch respecto de las modalidades que caracterizaron el accionar de los Estados latinoamericanos durante el período aquí analizado.

IUPAC in Polymer Education
Authors: Fellows Christopher , Theato Patrick
Published: November 2017

For as long as the Polymer Division of IUPAC has existed, it has put a high priority on education. In 1996, it first supported a dedicated educational project in the form of the UNESCO/IUPAC Postgraduate Course in Polymer Science, which continues to be organised annually by the Institute of Macromolecular Science in the Czech Republic and supported by the Polymer Division. In 2005, the Division IV Subcommittee on Polymer Education (SPEd) was established “to bring existing educational activities under one roof, to emphasise the importance of polymer education as well as the dedication of the IUPAC Polymer Division to this important field” [1]. Since then, educational projects have been the focus of this subcommittee. It has provided a forum for exchange of practice in polymer education worldwide, supported workshops in polymer science for undergraduates and postgraduate students on most continents, developed its own educational resources for free distribution to the world, and provided a website linking to other groups active in polymer education and other education resources.
IUPAC Polymer Conferences

Published: November 2017

It is now almost 100 years since Staudinger’s pioneering work that can be taken as the start of polymer science [1]. However, it took more than another 10 years until the concept of macromolecules began slowly to be accepted by the scientific community, and the Nobel Prize was not awarded to Staudinger until 1953. The first IUPAC publication about nomenclature of macromolecules [2] was published by the Sub-Commission on Nomenclature of the IUPAC Commission on Macromolecules (Chair H. F. Mark) in 1952. The Macromolecular Division, the 50th birthday of which we celebrate this year, was founded in 1967. Within this IUPAC Division IV there was also founded a Commission on Macromolecular Nomenclature in 1968 with Kurt Loening as its Chair. However, the division goal always was clearly defined by the principles upon which to this day the Union is founded:
Trump, Congress, and Health Care: All Politics Is National
Authors: Dickinson Matthew J. , Reinmuth Kate
Published: November 2017

John McCain’s dramatic early-morning “no” vote may have been the immediate cause of the Republican failure to repeal and replace Obamacare. However, Republicans undertook this endeavor from a weak political vantage point. The 2016 elections gave Republicans very little margin for error in Congress – a margin threatened by Trump’s inexperience and lack of political capital. Longer-term trends, including the polarization of the two congressional parties against the backdrop of increasingly nationalized elections, exacerbated this situation by leaving Trump and Republicans little choice but to legislate through their own party caucus – or to not legislate at all.
‘I Alone Can Fix It’ Donald Trump, the Administrative Presidency, and Hazards of Executive-Centered Partisanship
Authors: Milkis Sidney M. , Jacobs Nicholas
Published: November 2017

Eight months into his presidency, most depict the Trump administration as being mired in chaos and frenzy. Such a perspective, however, overlooks the aggressive pursuit of Trump’s campaign agenda through unilateral administrative action. Far from “deconstructing the administrative state” as promised, Trump has embraced the levers of presidential discretion and power inherent within the modern executive office. Although Trump cannot lay claim to any major legislative achievement early in his presidency, we argue that there is plenty he can take credit – or blame – for in fulfilling his campaign promises. Moreover, far from using administrative power to simply roll back his predecessor’s programmatic goals, the new president has sought to redeploy state resources in ways that will further entrench traditional commitments of the Republican Party, while simultaneously redefining them to mirror the president’s personal policy objectives. This is not a new development. Rather it is the culmination of a decades-long reorientation within both major parties: the rise of an executive centered party-system. As such, Trump – despite his seeming idiosyncrasies – might further reinforce the centrality of executive actions as a way to overcome both parties’ institutional weakness and ideological polarization.

Cigarette smoking among adolescents and its consequences are categorized as serious health problems. Cigarette craving is influenced by various psycho-social factors.

Objective

This study aimed to investigate desire and intention to smoke based on mindfulness and emotional self-regulation in adolescents.

Methods

In this correlational study conducted based on structural equation modeling, a sample of 350 male students was randomly selected from different schools of education districts in Isfahan. Three questionnaires, including Hooked on Nicotine Checklist, emotional regulation inventory, and Mindful Attention Awareness Scale were employed. Data were analyzed using χ2, correlation coefficient and structural modeling tests. In this regard, SPSS and AMOS software were used.

Results

The results showed that 62% of male students had experienced cigarette smoking at least once. There was a significant inverse correlation between cigarette craving and emotional reappraisal (r = −0.48), expressive suppression (r = −0.58) and mindfulness (r = −0.55), respectively (p < 0.01). In addition to the direct effect, mindfulness through emotional self-regulation had indirect effects on nicotine craving. A total of 58% of the variance in nicotine craving was explained by the study variables.

Conclusion

The results showed that the high percentage of male students hooked on smoking is an important issue. In this regard, students’ psychological issues such as efficient mechanisms of emotional regulation and their knowledge of the risks of smoking must be addressed by authorities and families.

We provide an analysis of the revenue-maximizing top earned income tax rate for a country with one of the highest levels of earnings taxation in the world, Finland, and compare it to the current level of taxation. We account for the effect of income-shifting possibilities in the calculations and find that the current top tax rate on earnings in Finland is likely to be below the revenue-maximizing rate. We provide an explicit account of assumptions behind the Laffer curve calculations and demonstrate that policy conclusions depend critically on non-trivial choices regarding, for example, how the current top tax rate is calculated. The assumptions in the Laffer curve calculations need to be made explicit if the calculations are to provide guidance for policy.
It’s all about logics?! Analyzing the rhetorical structure of multimodal filmic text
Authors: Wildfeuer Janina
Published: November 2017

This paper focuses on questions concerning the process of making meaning out of the filmic text by asking for the argumentative patterns that enable the recipient’s inference processes during his/her interpretation. Film analysis, and multimodal analysis in general, is no longer seen as simply decoding the semiotic resources, but asking for inferential processes of reasoning about the best and most plausible interpretation. For this, the paper presents an analytical approach based on recent advancements in contemporary discourse semantics and multimodal discourse analysis which outlines the discursive and rhetorical structure of filmic text and retraces the inference process of the recipient in detail. The aim is to show how multimodal film leads its spectators to acknowledge the argumentative reconstruction of its content by relating the diegetic world to its reality and proving its validity. An example analysis of the short filmEl Vendedor de Humo(2012) shows how it is possible to elucidate a film’s rhetorical structure and to outline the process of logically reasoning about semantic and pragmatic information in the text. The aim is thus to gain a detailed look at how premises and arguments for the interpretation are made available in multimodal context and how they are operated by the recipient.

Authors: Chabrol Claude
Published: November 2017

The specific object of research presented in this article is theoretical and empirical. The text situates its psycho-socio-semiotic problematic in relation to other semiotic paradigms, then applies the framework to analyze the reception of programmed variations in the discourse of highway safety. The goal is to evaluate the effect of the different linguistic, discursive, and iconic strategies when the seriousness of the danger is varied on the iconic and textual plane with respect to the evaluation of the risks for oneself and with respect to the level of comparative optimism.
Herta Müller: por uma ética da alteridade
Authors: Costa do Lago Thalyta Bruna , Ribeiro Helano Jader
Published: November 2017

Resumo: O presente trabalho propõe uma análise dos aspectos responsáveis por constituir uma obra autobiográfica inclinando-se, primordialmente, para o relato de si a partir do relato do outro. Para tanto, analisaremos o romance Tudo o que tenho levo comigo, de Herta Müller. Trata-se de uma obra construída através de cartas escritas por seu amigo Oscar Pastior, nas quais ele relata as experiências vividas durante o período em que foi mantido em um “gulag” - campo soviético de trabalho forçado- após o término da Segunda Guerra Mundial. Além do trauma como experiência de mudez vivida pelo jovem, a obra também se encarrega de retratar a dificuldade enfrentada por ele em retornar à família. Herta e Pastior desejavam escrever o livro juntos, no entanto, a morte de Pastior ocorrida no ano de 2006 impossibilitou que o projeto se concretizasse. Posteriormente, Herta escreveu a obra com o auxílio das cartas deixadas por ele, e é nesse ponto que devemos nos ater, pois através dele é possível começarmos a pensar sobre os jogos do discurso de si através do discurso do outro (“alteridade”), a reconstrução da memória a partir da memória do outro. A análise dos aspectos da obra se deu à luz de questões essenciais, tais como, a “ética da alteridade” de Emmanuel Lévinas, a qual nos permite compreender o processo de constituição do sujeito a partir do outro, o conceito de “trauma” de Sigmund Freud, para esclarecermos a relação existente entre o trauma e a história, o “conceito de origem” proposto por  Walter Benjamin.
Clash of Cultures. Formen der Begegnung mit dem Fremden in Texten von Christiane Neudecker

Konzepte von Fremdheit besitzen im zeitgenössischen abendländischen Diskurs und nicht zuletzt auch in der aktuellen Theoriebildung von Geistes- und Kulturwissenschaften besondere Virulenz, wie sich unter anderem an der Fülle aktueller Publikationen zu diesem Themenkomplex ablesen lässt. In Zeiten zunehmender Globalisierung und damit einhergehender räumlicher wie kultureller Entgrenzung besteht eine immer dringlichere Notwendigkeit der Reflexion darüber, wie im ‚global village‘ mit kulturellen, politischen oder religiösen Alteritäten umgegangen werden kann, ohne den Anderen auf unzulässige Weise festzuschreiben, ihn egologisch zu vereinnahmen und das dahinter stehende eigene Denk- und Wertesystem somit implizit oder explizit zu superiorisieren

A luz ultravioleta (UV) possui ação germicida, sendo amplamente utilizada na descontaminação de superfícies e materiais em laboratório. Essa radiação provoca alterações fotobioquímicas que promovem a inviabilidade ou morte dos micro-organismos atingidos. As leveduras são células eucariotas, sendo assim, possuem núcleo que protege o seu material genético, necessitando de uma maior exposição à UV quando comparadas às células procariotas. O objetivo deste trabalho foi avaliar a eficiência da radiação ultravioleta sobre as leveduras expostas em cabine de segurança biológica. No estudo foram utilizados um isolado de Cryptoccocus gattii, um de Rhodotorula sp. e uma cepa padrão de Candida albicans (ATCC 14053). Utilizou-se a Norma M27-A2 do NCCLS para a preparação dos inóculos, diluindo-os nas concentrações 1, 5 e 10 da escala McFarland. Cada inóculo foi semeado em seis placas de Potato Dextrose Agar (PDA). Após, metade das placas foi exposta à radiação ultravioleta por 15 minutos em cabine de segurança biológica. Todas as placas foram incubadas em estufa a 37 °C por 10 dias. As placas semeadas com C. albicans e C. gattii e expostas à UV tiveram seu crescimento inibido. As placas semeadas com Rhodotorula sp. e expostas à radiação UV tiveram crescimento, porém com uma diminuição nas unidades formadoras de colônias (UFC) quando comparadas com as não expostas. Nas condições deste trabalho, comprovou-se a eficácia desse método de descontaminação em relação a C. albicans e C. gattii, assim como a necessidade de maiores pesquisas da atuação da UV diante do gênero Rhodotorula.

O controle dos helmintos gastrintestinais em ovinos, realizado exclusivamente através de anti-helmínticos, tem como consequência a seleção de populações de helmintos resistentes a praticamente todos os fármacos disponíveis. Isso tem motivado à busca de alternativas para controle, entre as quais destacamos a utilização de fitoterápicos. Neste contexto, o objetivo deste estudo foi avaliar a atividade ovicida in vitro do óleo essencial e do extrato hidroalcoólico de Ocimum basilicum em nematódeos de ovinos e determinar os constituintes químicos majoritários do óleo essencial. Para os estudos in vitro foram utilizadas fezes de ovinos naturalmente infectados, testadas frente ao óleo essencial de O. basilicum nas concentrações de 32 a 0,25 mg/mL e ao extrato hidroalcoólico nas concentrações 40 a 1,25 mg/mL. Como controle positivo foi utilizado o princípio ativo tiabendazol (0,025 mg/mL) e negativo a água destilada. A análise química do óleo essencial determinou como constituintes majoritários chavicol (34,68%) e linalool (27,68%). O óleo essencial apresentou atividade ovicida acima de 99% em todas as concentrações testadas. O extrato hidroalcoólico nas concentrações entre 40 e 20 mg/mL obteve 100% de ação, decrescendo a partir de 10 mg/mL, atingindo 9,76% de atividade na concentração 1,25 mg/mL. Os controles, positivo e negativo, obtiveram 98,57% e 8,5%, respectivamente. O valor da concentração letal média (CL50) do extrato hidroalcoólico e óleo essencial foram de 4,797 mg/mL e 0,2123 mg/mL, respectivamente. O. basilicum apresentou ação anti-helmíntica in vitro sobre ovos de nematódeos gastrintestinais de ovinos, com maior potencial para o óleo essencial, constituindo um promissor fitoterápico para estudos visando à busca de moléculas bioativas para serem utilizadas no controle dos nematódeos gastrintestinais.
