Cutaneous Wart

Bovine papilomavírus (BPVs) is the etiological agent of bovine papillomatosis, a disease that triggers warts throughout the skin, udder, roofs, genitalia and in more severe cases can develop extensive papillomas, cause neoplasia in the digestive tract and bladder, cause losses in productivity and losses to livestock. In Brazil, the occurrence of BPV infection is relatively common, but the identification of viral types is still sporadic. The present study is a research report that aimed to describe the occurrence of BPV infections in dairy cattle affected by papillomatosis, based on the nucleotide sequences of the ORF L1, the most conserved sequence. Twenty-five samples of cutaneous wart from nine cattle clinically diagnosed as cutaneous papillomatosis were analyzed in the state of Goiás, central-western Brazil. Amplification was obtained in 11 samples (papilloma) from different cattle. PCR reactions followed by sequencing revealed the presence of BPV-1 in 60%, BPV-5 in 40%, and BPV-14 in 20% of the samples analyzed. The presence of coinfection was verified in 60% of the amplified samples. These data suggest that several types of BPV can infect a lesion simultaneously and demonstrate the possibility that BPV infection in epithelial tissue can occur without restriction to one or two viral types, demonstrating the region's genetic diversity. As far as we know, this is the first registry of typification of BPVs of the central-western region of Brazil. This analysis provides important information for bovine papillomavirus (BPV) research in Brazil.

Hypothesizing after the results are known, or HARKing, occurs when researchers check their research results and then add or remove hypotheses on the basis of those results without acknowledging this process in their research report ( Kerr, 1998 ). In the present article, I discuss 3 forms of HARKing: (a) using current results to construct post hoc hypotheses that are then reported as if they were a priori hypotheses; (b) retrieving hypotheses from a post hoc literature search and reporting them as a priori hypotheses; and (c) failing to report a priori hypotheses that are unsupported by the current results. These 3 types of HARKing are often characterized as being bad for science and a potential cause of the current replication crisis. In the present article, I use insights from the philosophy of science to present a more nuanced view. Specifically, I identify the conditions under which each of these 3 types of HARKing is most and least likely to be bad for science. I conclude with a brief discussion about the ethics of each type of HARKing.

Centrifugal Action

Abstract Liquid, supplied through a stationary tube to the inner part of a rotating cup widening toward a brim, flows viscously in a thin layer toward this brim and is then flung off, all by centrifugal action. The flow within this layer and the disintegration phenomena occurring beyond the brim have been studied, experimentally as well as theoretically. A formula has been derived for the thickness and for the radial velocity of the liquid layer within the cup, which proved to agree reasonably well with experimental results. Three essentially different types of disintegration may take place around and beyond the edge of the cup designated, respectively, by: (a) the state of direct drop formation; (b) the state of ligament formation; and (c) the state of film formation. Which one of these is realized depends upon working conditions. Transition from state (a) into (b), or of state (b) into state (c) is promoted by an increased quantity of supply, an increased angular speed, a decreased diameter of the cup, an increased density, an increased viscosity, and a decreased surface tension of the liquid. The experimental results have been expressed in relationships between relevant dimensionless groups. For the state of ligament formation a semiempirical relationship has been derived between the number of ligaments and dimensionless groups determining the working conditions of the cup. Results of drop-size measurements made for the state of ligament formation as well as for the state of film formation show that atomization by mere rotation of the cup is much more uniform than commonly achieved with pressure atomizers.

This study assesses the significance of different types of tourists to Victoria, Australia, by their relative contribution to the economy. Differential impacts are calculated using an input–output model incorporating marginal household coefficients. The analysis demonstrates that the conventional input–output model can overestimate the flow-on effects to value added, income and employment by a significant amount. It finds that domestic tourists are the largest contributor to the State economy, with day-trippers spending the greatest amount. International tourists rank last in terms of economic impacts on the state.

The commentaries on this forum’s anchor article, ‘China’s Integration into the Global Financial System: Toward a State-led Conception of Global Financial Networks’, examine how the state is shaping global financial networks (GFNs). In response to these reviews, this article discusses three common themes that bind the different commentaries: (1) different types of agency, power, and the rise of new actors; (2) the methodology behind studying state-led GFNs; and (3) the structural question of ‘Chinese exceptionalism’ as a mode of capitalism. Overall, this article affirms that the state remains central to our understanding of competitive hierarchies and firm behavior in financial networks.

O número de nematódeos descritos em elasmobrânquios é relativamente pequeno, sendo encontrados majoritariamente no trato digestório. Apesar de alguns relatos descritos, a literatura a respeito ainda é considerada escassa principalmente sobre a associação parasita-hospedeiro. Diante disso, o objetivo deste trabalho foi avaliar os índices parasitários de larvas Brevimulticaecum sp. na válvula espiral de Potamotrygon motoro provenientes do arquipélago do Bailique, em Macapá no estado do Amapá, Brasil. Registrou-se em 20,41% das raias coletadas a presença de larvas de Brevimulticaecum sp., sendo a intensidade média de 20,10 larvas/peixe e a abundância média de 4,10. São poucos os registros deste parasito em peixes no Brasil, sendo que já foi relatada sua ocorrência no estômago de P. motoro e Potamotrygon falkneri. As diferenças entre os parâmetros parasitários podem ser um indicador de alimentação e/ou diferenças comportamentais entre os sexos. Este é o primeiro estudo sobre nematóides de potamotrigonídeos na região Norte, ampliando o conhecimento da biodiversidade desta região.   Palavras-chave: Helmintos. Nematoda; Elasmobrânquio. Válvula Espiral.   Abstract The number of nematodes described in elasmobranchs is relatively small, being found mostly in the digestive tract. Despite some reports described, the literature on this subject is still considered scarce, mainly on the parasite-host association. Therefore, the objective of this work was to evaluate the parasitic indices of Brevimulticaecum sp. the Potamotrygon motoro spiral valve from the Bailique archipelago, in Macapá in the state of Amapá, Brazil. Larvae of Brevimulticaecum sp. Were recorded in 20.41% of the rays collected, with an average intensity of 20.10 larvae / fish and an average abundance of 4.10. There are few records of this parasite in fish in Brazil, and its occurrence in the stomach of P. motoro and Potamotrygon falkneri has been reported. Differences between parasitic parameters can be an indicator of diet and / or behavioral differences between genders. This is the first study on potamotrigonid nematodes in the North, expanding knowledge of this region's biodiversity.   Keywords: Helminths. Nematoda. Elasmobranchs. Spiral Valve.

While children’s experiences of online risks and harm is a growing area of research in New Zealand, public discussion on the matter has largely been informed by mainstream media’s fixation on the dangers of technology. At best, debate on risks online has relied on overseas evidence. However, insights reflecting the New Zealand context and based on representative data are still needed to guide policy discussion, create awareness, and inform the implementation of prevention and support programmes for children. This research report presents findings from a quantitative study regarding different aspects related to risks and online safety. It looks at the online experiences that children find bothersome and upsetting and explores the hurtful behaviours they encounter or engage in, both online and in person. Evidence regarding exposure to different types of potentially harmful online content is also presented. Another relevant contribution is the insights related to excessive internet use.The findings presented in this report are based on data from 2,061 New Zealand children aged 9-17. We hope the findings will contribute to the development of policies, practices and services designed to support New Zealand children to safely take advantage of the opportunities available to them online.
