Next-generation sequencing reveals large connected networks of intra-host HCV variants

Background: Next-generation sequencing (NGS) allows for sampling numerous viral variants from infected patients. This provides a novel opportunity to represent and study the mutational landscape of Hepatitis C Virus (HCV) within a single host.Results: Intra-host variants of the HCV E1/E2 region were extensively sampled from 58 chronically infected patients. After NGS error correction, the average number of reads and variants obtained from each sample were 3202 and 464, respectively. The distance between each pair of variants was calculated and networks were created for each patient, where each node is a variant and two nodes are connected by a link if the nucleotide distance between them is 1. The work focused on large components having > 5% of all reads, which in average account for 93.7% of all reads found in a patient. The distance between any two variants calculated over the component correlated strongly with nucleotide distances (r = 0.9499; p = 0.0001), a better correlation than the one obtained with Neighbour-Joining trees (r = 0.7624; p = 0.0001). In each patient, components were well separated, with the average distance between (6.53%) being 10 times greater than within each component (0.68%). The ratio of nonsynonymous to synonymous changes was calculated and some patients (6.9%) showed a mixture of networks under strong negative and positive selection. All components were robust to in silico stochastic sampling; even after randomly removing 85% of all reads, the largest connected component in the new subsample still involved 82.4% of remaining nodes. In vitro sampling showed that 93.02% of components present in the original sample were also found in experimental replicas, with 81.6% of reads found in both. When syringe-sharing transmission events were simulated, 91.2% of all simulated transmission events seeded all components present in the source.Conclusions: Most intra-host variants are organized into distinct single-mutation components that are: well separated from each other, represent genetic distances between viral variants, robust to sampling, reproducible and likely seeded during transmission events. Facilitated by NGS, large components offer a novel evolutionary framework for genetic analysis of intra-host viral populations and understanding transmission, immune escape and drug resistance.

FROM FACTORY-FLOOR TO UNIVERSITY

The interaction between industry and university is often discussed. Industry participants feel they do not have enough time to spend with academics because of tight deadlines to achieve your goals. The other hand, professors and his students do not have availability and resources for responding quickly to industry activities. Both sides recognize the associated problems and feel the consequences of various forms. One way to reduce the distance between them is to provide industrial labs that resemble the factory floor at the university. Thus not only students may work on a real technological base, but also the industry's problems can be brought to the university laboratory. To ensure that relevant industrial problems will be studied, the industry needs help in the formulation of the problem being researched. The graduate program of Automation and Control Engineering from UNESP Sorocaba is aimed at training human resources with skills in automation and control activities related to the development of automatic control processes, integrating electronic commands, intelligent manufacturing and industrial robotics. In order to achieve its objectives, one of the pillars of the university consists of a wide range of modern equipments and software for industrial automation, which allows the circuit assembly from most primitive until configuration and programming of a complex system of integrated manufacturing. This paper describes industrial automation equipments and laboratory structure offered to students of Control and Automation Engineering graduate program at UNESP Sorocaba as alternative to close technologies and real problems on the job until academic world. The strategic is to do students understand theory and operations in robotic and industrial automation by means to manipulating real production systems locate at university

Análise dialógica do discurso publicitário

From the questions raised by Bakhtin Circle, especially those intended to gender and dialogue, this work aims to study the relationships of meaning that are established between the statements present in commercial advertising discourse. For each sphere of production, circulation and reception of discourses, genres are appropriate, therefore, all discourse requires a different choice of language resources, which determines, among other things, the style of the message. The advertising genre, a genre characterized as complex, as it works, reframes and incorporates primary genres, has the central objective of building the next one idea being to buy something more frequent. This process occurs mainly through the use of persuasive speeches, compelling, authoritative, imperative and seduction. Our goal is to analyze an advertising piece, discussing how the resources used in advertising participate in the process of enunciation and persuasion and the manner in which the voices of others (previous authors, recipients hypothetical ) mingle with the voice of the subject's explicit enunciation. (Bakhtin, 2010, p. XXVII). Thus, based on Bakhtinian studies, we will think about the relation of the dialogical voices raised in question in advertising, and attend to the role of the other, with his active responsive understanding, how to be active and modifying agent

Subluxação atlantoaxial canina

The atlantoaxial subluxation or luxation is an instability of this articulation that produces excessive flexion of this joint causing the cranial aspect of the axis to rotate dorsally into the vertebral channel with subsequent spinal cord compression. This disorder is most commonly found in young small breed dogs. The diagnosis of this disease is done by survey radiographs, where there is a larger distance between the atlas dorsal arch and the axis spinal process characterize the atlantoaxial subluxation. Surgical stabilization is the treatment of choice and multiple implants show the best results to stabilize the atlantoaxial joint. The main complications are sudden death or implant failure. The sudden death happens because of cardiorespiratory arrest and it is most likely caused by brainstem iatrogenic trauma. However, a larger study comparing different surgical stabilization techniques should be performed to evaluate relative success rates in dogs that have the same initial neurologic status

Inventário da ictiofauna do alto rio Paraíba do Sul e caracterização molecular das espécies encontradas

The state of São Paulo has four main drainages: Paraná river, Paraíba do Sul river, Ribeira do Iguape river and coastal rivers. The Paraíba do Sul river is born in Sao Paulo and drains an important range of land east of the state. Its ichthyofauna has some similarities and many differences from the continental and coastal drainages which highlights the importance of this study. Surveys conducted in the ichthyofauna of this basin, as in other large river basins in Brazil, is still incomplete. Moreover, there is no consensus about the taxonomic status of many species listed in these surveys. Considering the promising use of DNA barcode as a global system for species identification, the present study is aimed to establishing an inventory of the ichthyofauna of the São Paulo portion of the river Paraíba do Sul and simultaneously build a DNA barcode reference sequence library for fish found. Were obtained and analyzed 354 sequences of the gene cytochrome oxidase c subunit I (COI) belonging to 66 species of São Paulo portion of the Paraíba do Sul river. The average K2P distance between individuals within species of this basin was 0.48%, and 9,87% between species within a genus. Five pairs of species (10 species) showed low levels of interspecific genetic divergence (<2%),but all could be correctly identified. This study showed that the fish species analyzed could be identified efficiently through the use of barcode generating data that can provide information for further studies of this fauna, besides contributing to the global initiative to characterize the species of fish in the world of a molecular point of view.

Abordagem multivariada na análise de diversidade genética em cruzamentos para alto teor de óleo em soja

The soybean crop is considered a high expression around the world. In plant breeding programs, knowledge of genetic diversity is extremely important and in this context, are frequently used multivariate analyzes. Thus, the aim of the present study was to evaluate the genetic divergence between soybean crosses through multivariate techniques. In total, 16 crosses were evaluated, which were in the F2 generation of inbreeding. The evaluated characteristics were plant height at maturity, height of the first pod, number of branches per plant, number of pods per plant, number of nodes per plant, hundred seed weight, grain yield and oil content. For the analyzes was used Euclidean distance, methods of hierarchical clustering UPGMA and Ward and principal component analysis. Genetic distances estimated using Euclidean distance ranged from 1.24 to 8.13, with the smallest distance observed between crosses C1 and C4, and the greatest distance between the C2 crosses and C6. The methods UPGMA clustering and Ward met crossings in five different groups. The principal component analysis explained 86.2% of the variance contained in the original eight variables with three main components. The APM characters, NV, NR, NN, PG% and oil were the main contributors to genetic divergence among traits. Multivariate techniques were crucial to the analysis of genetic diversity, and the methods of Ward and UPGMA clustering and principal components have consistent results in this way, the simultaneous use of these tools in genetic analysis of crosses is indicated

Biodiversidade e código florestal em Botucatu, um estudo de caso

The brazilian legislation has sufored changes by the law no 1876/99, without the scientific community consultation, causing grave consequences for the country natural patrimony. The goal of this research is to investigate what the professors and students community of a São Paulo University know about the theme, as much as a rural and urban portion of persons; what they consider important and which atributes are taken in consideration. By the elaboration of closed questionnaires, qualitative and quantitative datas were collected, organized and analysed. The datas showed a low schooling by the countrified people, which reflected the low forest law knowledge. The distance between the university and society was also noticed, which indicates the lack of extension activities, ethical commitment against knowledge, technology and the sustainable development of the country. Due to, highlight the importance of extension activities towards the university, community and a knowledge future of all

Resolução do problema de sequenciamento de múltiplas linhas de montagem de modelos mistos em ambiente de produção enxuta

This work deals with the sequencing of Multi-Mixed-Model Assembly Lines in a lean manufacturing environment, where an operational structure where several kanbans support several mixed-model assembly lines, so that all assembly lines can receive parts or sub-assemblies from all suppliers. To optimize this system, the sequencing seeks to minimize the distance between the real consumption and the constant ideal consumption of parts or subassemblies, thereby reducing the scaling of kanbans and intermediate stocks. To solve the sequencing problems, the method Clustering Search was applied along with the metaheuristics Variable Neighborhood Search, Simulation Annealing and Iterative Local Search. Instances from the literature and generated instances were tested, thus allowing comparing the methods to each other and with other methods presented in the literature. The performance of the Clustering Search with Iterated Local Search stands out by the quality and robustness of their solutions, and mainly for its efficiency, whereas it converges to better results at a lower computational cost
