AimsRestoring the pre-morbid anatomy of the proximal humerus is a goal of anatomical shoulder arthroplasty, but reliance is placed on the surgeon’s experience and on anatomical estimations. The purpose of this study was to present a novel method, ‘Statistical Shape Modelling’, which accurately predicts the pre-morbid proximal humeral anatomy and calculates the 3D geometric parameters needed to restore normal anatomy in patients with severe degenerative osteoarthritis or a fracture of the proximal humerus.Materials and MethodsFrom a database of 57 humeral CT scans 3D humeral reconstructions were manually created. The reconstructions were used to construct a statistical shape model (SSM), which was then tested on a second set of 52 scans. For each humerus in the second set, 3D reconstructions of four diaphyseal segments of varying lengths were created. These reconstructions were chosen to mimic severe osteoarthritis, a fracture of the surgical neck of the humerus and a proximal humeral fracture with diaphyseal extension. The SSM was then applied to the diaphyseal segments to see how well it predicted proximal morphology, using the actual proximal humeral morphology for comparison.ResultsWith the metaphysis included, mimicking osteoarthritis, the errors of prediction for retroversion, inclination, height, radius of curvature and posterior and medial offset of the head of the humerus were 2.9° (± 2.3°), 4.0° (± 3.3°), 1.0 mm (± 0.8 mm), 0.8 mm (± 0.6 mm), 0.7 mm (± 0.5 mm) and 1.0 mm (± 0.7 mm), respectively. With the metaphysis excluded, mimicking a fracture of the surgical neck, the errors of prediction for retroversion, inclination, height, radius of curvature and posterior and medial offset of the head of the humerus were 3.8° (± 2.9°), 3.9° (± 3.4°), 2.4 mm (± 1.9 mm), 1.3 mm (± 0.9 mm), 0.8 mm (± 0.5 mm) and 0.9 mm (± 0.6 mm), respectively.ConclusionThis study reports a novel, computerised method that accurately predicts the pre-morbid proximal humeral anatomy even in challenging situations. This information can be used in the surgical planning and operative reconstruction of patients with severe degenerative osteoarthritis or with a fracture of the proximal humerus.

Diagnostic use of intramedullary reaming biopsy in metastatic long bone disease
Authors: Afinowi RA , Chaturvedi A , Cattermole HR 
Published: June 2017

INTRODUCTION Bone is the third most common site of metastasis. A histological diagnosis is important in guiding therapy and prognosis. In up to 15% of cases of metastatic disease, the primary tumour remains unknown. This emphasises the importance of adequate, reliable and accurate sampling when performing any type of biopsy. Reaming biopsy is commonly performed during intramedullary nailing of metastatic long-bone disease but there is little published evidence on the diagnostic use and reliability of this technique. AIMS AND METHODS We reviewed 49 cases of confirmed metastatic bone disease to determine adequacy for analysis, diagnostic accuracy and factors affecting reliability. RESULTS Adequate tissue for histopathological analysis was obtained in 96% of cases but metastasis was confirmed in only 51% of cases. The presence of a pathological fracture had no effect on accuracy of the results but metastasis was more likely to be missed in the presence of tissue crushing and or necrosis (P = 0.015). DISCUSSION This study determines the use and accuracy of bone reaming biopsy in metastatic disease and, to the best of our knowledge, is the only study determining the effect of additional factors such as the presence of a pathological fracture and tissue necrosis or crushing on the diagnostic accuracy of this technique. CONCLUSIONS In spite of adequate tissue sampling, the diagnostic accuracy and, hence, reliability of intramedullary reaming biopsy in metastatic bone disease is less than optimal. A reaming histopathology report suggesting no evident metastasis should always be taken in clinical context.

Published: June 2017

INTRODUCTION The aim of this study was to investigate whether the pedicle of the rectus abdominis flap can be lengthened by resecting the inferior costal cartilage segments or associated muscle when repairing upper body defects. A formula was generated that calculates the expected increase in pedicle length. METHODS Thirty patients underwent computed tomography. The width and thickness of the third to seventh inferior costal cartilage segments as well as the width of the respective intercostal spaces were recorded. Four patients underwent reconstruction of an upper body defect with the relevant flap. RESULTS The expected mean increases in pedicle length were 4.07cm (standard deviation [SD]: 0.31cm) and 4.63cm (SD: 0.54cm) following resection of the left and right sides respectively of the seventh inferior costal cartilage segment, 7.99cm (SD: 0.49cm) and 10.82cm (SD: 0.23cm) following resection of the left and right sides respectively of the sixth and seventh inferior costal cartilage segments while resection of the fourth to seventh inferior costal cartilage segments would equate to increases of 17.48cm (SD: 0.62cm) and 22.05cm (SD: 0.21cm) for the left and right sides respectively. In four patients who required reconstruction, three flaps survived without problems but one flap developed partial necrosis. CONCLUSIONS Resecting inferior costal cartilage segments or associated muscle can lengthen the pedicle of the rectus abdominis flap for reconstruction of defects on the upper chest and neck.

La supervisión del microclima en invernaderos de la región de Norte de Santander se realiza por parte de los agricultores mediante una estimación intuitiva basada en su actividad empírica adquirida durante los años. Un método que es completamente inadecuado y subjetivo, lo que repercute de manera negativa en el desarrollo y rendimiento de los cultivos, limitando su calidad y producción. Por tal razón, este método de agricultura exige el desarrollo y la implementación de tecnologías eficaces que ayuden al mejoramiento de la producción. Teniendo en cuenta los bajos ingresos y bajas inversiones de capital de los pequeños agricultores, el acceso a estos sistemas de supervisión representa un alto costo de inversión y desarrollo, por lo que en muchos casos optan por prescindir de las ventajas que estas tecnologías puedan ofrecerles. Por lo tanto, en este artículo se presenta el diseño y la implementación de un sistema modular de bajo costo que permite la supervisión de variables ambientales en un invernadero. El sistema funciona con el protocolo ZigBee y emplea una red inalámbrica de sensores para recolectar información acerca de la humedad, la temperatura y la luminosidad, la almacena en una base de datos y permite su visualización gráfica en tiempo real y en reportes históricos. El sistema desarrollado tiene la capacidad de transmitir la información medida con un porcentaje de paquetes recibidos entre el 70 % y el 100 %. Además, los nodos alcanzan una reducción de costos mayor al 80 % respecto a nodos comerciales similares.

Modulation of Complex-Spike Duration and Probability during Cerebellar Motor Learning in Visually Guided Smooth-Pursuit Eye Movements of Monkeys
Authors: Yang Yan , Lisberger Stephen G. 
Published: June 2017

AbstractActivation of an inferior olivary neuron powerfully excites Purkinje cells via its climbing fiber input and triggers a characteristic high-frequency burst, known as the complex spike (CS). The theory of cerebellar learning postulates that the CS induces long-lasting depression of the strength of synapses from active parallel fibers onto Purkinje cells, and that synaptic depression leads to changes in behavior. Prior reports showed that a CS on one learning trial is linked to a properly timed depression of simple spikes on the subsequent trial, as well as a learned change in pursuit eye movement. Further, the duration of a CS is a graded instruction for single-trial plasticity and behavioral learning. We now show across multiple learning paradigms that both the probability and duration of CS responses are correlated with the magnitudes of neural and behavioral learning in awake behaving monkeys. When the direction of the instruction for learning repeatedly was in the same direction or alternated directions, the duration and probability of CS responses decreased over a learning block along with the magnitude of trial-over-trial neural learning. When the direction of the instruction was randomized, CS duration, CS probability, and neural and behavioral learning remained stable across time. In contrast to depression, potentiation of simple-spike firing rate for ON-direction learning instructions follows a longer time course and plays a larger role as depression wanes. Computational analysis provides a model that accounts fully for the detailed statistics of a complex set of data.
Context Mediated
Authors: Pickford Benjamin 
Published: June 2017

Benjamin Pickford, “Context Mediated: Ralph Waldo Emerson’s Political Economy of Plagiarism” (pp. 35–63)
Context has long been a critical determiner of methodologies for literary studies, granting scholars the tools to make objective claims about a text’s political or economic relation to the situation of its genesis. This essay argues that Ralph Waldo Emerson anticipatively criticizes our commitment to such practices through his use of plagiarism—a literary mode that exemplifies the denial of the sovereignty of context. I focus on two core principles that underlie Emerson’s conception of literature’s civic role in Essays: Second Series (1844): first, that literature is driven by an impulse to decontextualize; second, that this means that it has a deep affinity with the deterritorializing logic of capital. Provocatively proposing Emerson as a theorist of the relation between literature and economics, I argue that Essays: Second Series shows how the literary text can negotiate its ineluctable culpability with capitalism, but this does not mean that it can presume to possess a privileged point of vantage that might deny such culpability. Given that this is precisely what much historicizing or contextualizing scholarship implies, I contend that Emerson gives us a case study in the limits of literature and criticism’s economic agency.

Published: June 2017

В статті здійснено аналіз кредитування аграрних підприємств банківськими установами України. Аргументовано, що найбільшим фінансовим донором для суб’єктів господарювання аграрного сфери виступає банківський сектор. Доведено, що сутність державного регулювання у вирішенні питань кредитування аграрного бізнесу полягає у створенні сприятливої політики кредитування через часткову компенсацію ставки за кредитами банківських структур. Умотивовано, що зменшення рівня кредитування сільськогосподарських товаровиробників в період фінансової кризи обумовлено низкою чинників. Обгрунтовано, що ефективне господарювання не можливе без поповнення обсягів фінансових ресурсів для збільшення оборотного капіталу та інвестування діяльності суб’єктів господарювання, а, звідси, збільшення їх прибутковості. Аргументовано, що поповнення коштів можливе через залучення інвестицій з метою поповнення оборотних активів, що, у свою чергу, дасть можливість поповнити, оновити основні засоби виробництва та збільшити прибутковість господарюючих суб’єктів і для вирішення даних питань потрібна нагальна участь державних регуляторів.
Dissecting the Satellite DNA Landscape in Three CactophilicDrosophilaSequenced Genomes
Authors: de Lima Leonardo G , Svartman Marta , Kuhn Gustavo C S 
Published: June 2017

AbstractEukaryote genomes are replete with repetitive DNAs. This class includes tandemly repeated satellite DNAs (satDNA) which are among the most abundant, fast evolving (yet poorly studied) genomic components. Here, we used high-throughput sequencing data from three cactophilic Drosophila species, D. buzzatii, D. seriema, and D. mojavensis, to access and study their whole satDNA landscape. In total, the RepeatExplorer software identified five satDNAs, three previously described (pBuM, DBC-150 and CDSTR198) and two novel ones (CDSTR138 and CDSTR130). Only pBuM is shared among all three species. The satDNA repeat length falls within only two classes, between 130 and 200 bp or between 340 and 390 bp. FISH on metaphase and polytene chromosomes revealed the presence of satDNA arrays in at least one of the following genomic compartments: centromeric, telomeric, subtelomeric, or dispersed along euchromatin. The chromosomal distribution ranges from a single chromosome to almost all chromosomes of the complement. Fiber-FISH and sequence analysis of contigs revealed interspersion between pBuM and CDSTR130 in the microchromosomes of D. mojavensis. Phylogenetic analyses showed that the pBuM satDNA underwent concerted evolution at both interspecific and intraspecific levels. Based on RNA-seq data, we found transcription activity for pBuM (in D. mojavensis) and CDSTR198 (in D. buzzatii) in all five analyzed developmental stages, most notably in pupae and adult males. Our data revealed that cactophilic Drosophila present the lowest amount of satDNAs (1.9–2.9%) within the Drosophila genus reported so far. We discuss how our findings on the satDNA location, abundance, organization, and transcription activity may be related to functional aspects.
Evasão e abandono escolar na educação básica no Brasil: fatores, causas e possíveis consequências

Published: June 2017

Neste artigo, objetivou-se trazer para o debate algumas considerações sobre evasão e abandono escolar na educação brasileira. Verifica-se a necessidade de ter como eixo a compreensão de suas dimensionalidades, pois suas formas de interpretação não permitem chegar a uma definição precisa. Os próprios órgãos oficiais da educação trazem à tona a falta de conceito claro. Fatores internos e externos contribuem diretamente para que a evasão e o abandono se perpetuem. O Brasil tem a terceira maior taxa de abandono escolar entre os 100 países com maior IDH. A evasão é um processo muito complexo, dinâmico e cumulativo de saída do estudante e pode ser vista como expulsão escolar. As metas estipuladas pela Constituição Federal de 1988, que determinam a universalização do ensino fundamental e a “erradicação” do analfabetismo, ainda não se concretizaram. A “evasão” pode ser considerada um “ato solitário” e pode denotar o próprio fracasso das relações sociais; não tem uma origem definida e por isso não terá um fim por si só. Drogas, sucessivas reprovações, prostituição, falta de incentivo da família e da escola são alguns dos fatores que podem levar o educando a sair da escola. Observa-se que existem três dimensões conceituais indispensáveis à investigação da evasão escolar.

Published: June 2017

O PIBID/CAPES constitui-se em um espaço privilegiado para a formação dos estudantes de licenciatura, proporcionando uma inter-relação entre teoria e prática necessárias para o cotidiano profissional docente. As discussões que sustentam este trabalho tratam das contribuições do programa para a formação inicial de professores na área de Pedagogia. Utilizou-se uma abordagem quanti/qualitativa, do tipo estudo de caso, aplicando questionários que foram respondidos por 23 dos 30 bolsistas de Iniciação à Docência (ID) do subprojeto Pedagogia, de uma Instituição de Educação Superior comunitária e filantrópica do Rio Grande do Sul. O instrumento fez parte da autoavaliação institucional com o objetivo de analisar os impactos dos projetos desenvolvidos na formação dos estudantes na instituição. Foram avaliadas sete questões de múltipla escolha relativas ao desenvolvimento profissional docente dos bolsistas ID; segundo as respostas dos acadêmicos, os fatores de contribuição do PIBID agruparam-se nas seguintes categorias: relação teoria-prática, estímulo à produção de conhecimento a partir da prática, interesse em formação permanente e necessidade de inter-relação entre as áreas de conhecimento. Além disso, todos esses aspectos foram percebidos de forma consciente pelos estudantes, o que deixou evidente que o PIBID também contribui para a maturidade deles no exercício da futura profissão.
