Fundamental hemodynamic mechanisms mediating the response to myocardial ischemia in conscious paraplegic mice: cardiac output versus peripheral resistance
Authors: Lujan Heidi L. , DiCarlo Stephen E.
Published: March 2017

Autonomic dysfunction, a relative sedentary lifestyle, a reduced muscle mass and increased adiposity leads to metabolic abnormalities that accelerate the development of coronary artery disease (CAD) in individuals living with spinal cord injury (SCI). An untoward cardiac incident is related to the degree of CAD, suggesting that the occurrence of a significant cardiac event is significantly higher for individuals with SCI. Thus, understanding the fundamental hemodynamic mechanisms mediating the response to myocardial ischemia has the potential to positively impact individuals and families living with SCI. Accordingly, we systematically investigated if thoracic level 5 spinal cord transection (T5X; paraplegia) alters the arterial blood pressure response to coronary artery occlusion and if the different arterial blood pressure responses to coronary artery occlusion between intact and paraplegic mice are mediated by changes in cardiac output and or systemic peripheral resistance and whether differences in cardiac output are caused by changes in heart rate and or stroke volume. To achieve this goal, the tolerance to 3 min of coronary artery occlusion was determined in conscious intact and paraplegic mice. Paraplegic mice had an impaired ability to maintain arterial blood pressure during coronary artery occlusion as arterial pressure fell to near lethal levels by 1.38 ± 0.64 min. The lower arterial pressure was mediated by a lower cardiac output as systemic peripheral resistance was elevated in paraplegic mice. The lower cardiac output was mediated by a reduced heart rate and stroke volume. These results indicate that in paraplegic mice, the arterial pressure response to coronary artery occlusion is hemodynamically mediated primarily by cardiac output which is determined by heart rate and stroke volume.
Effect of pH on Structural, Magnetic and FMR Properties of Hydrothermally Prepared Nano Ni Ferrite
Authors: Lafta Sadeq H.
Published: March 2017

Nano nickel ferrite particles were prepared at pH values 1.5, 4, 7, 10, 13 by a hydrothermal method using metal chlorides and NaOH as an oxidant and solution basicity controller. There is a phase transition from hematite to spinel ferrite that begins when the pH reaches 4. The lowest crystallite size (4 nm) was associated with a highest lattice constant (8.345 Å), at pH=4. Whereas maximum crystallite size 64.5 nm corresponds lattice constant of 8.298 Å at pH=10. The highest magnetization (48 emu/g) value was achieved for the sample prepared at pH=7, which at the same time has a lower coercivity. The samples synthesized at pH ≥4 show superparamagnetic behavior owing to its low particle size and to zero field cooling and field cooling measurements. The ferromagnetic resonance (FMR) cavity tests analysis show that the broadened linewidth (770 Oe) and high imaginary permeability or high microwave absorption which is linked to high magnetization and low coercivity of superparamagnetic particles and their aggregation. There was a shift in the resonance field due to internal fields and cation distribution.
Does Macaulay Duration Provide The Most Cost-Effective Immunization Method – A Theoretical Approach
Authors: Zaremba Leszek
Published: March 2017

In the following, we offer a theoretical approach that attempts to explain (Comments 1-3) why and when the Macaulay duration concept happens to be a good approximation of a bond’s price sensitivity. We are concerned with the basic immunization problem with a single liability to be discharged at a future time q. Our idea is to divide the class K of all shifts a(t) of a term structure of interest rates s(t) into many classes and then to find a sufficient and necessary condition a given bond portfolio, dependent on a class of shifts, must satisfy to secure immunization at time q against all shifts a(t) from that class. For this purpose, we introduce the notions of dedicated duration and dedicated convexity. For each class of shifts, we show how to choose from a bond market under consideration a portfolio with maximal dedicated convexity among all immunizing portfolios. We demonstrate that the portfolio yields the maximal unanticipated rate of return and appears to be uniquely determined as a barbell strategy (portfolio) built up with 2 zero-coupon bearing bonds with maximal and respective minimal dedicated durations. Finally, an open problem addressed to researchers performing empirical studies is formulated.

Coexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients.

A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia. Taking into consideration good blood supply to the axillary artery via reversed blood flow in the thyreocervical trunk, hence we decided not to proceed with cervicoaxillary bypass grafting.

Implantation stent-graft into aorta coarctation with covering axillary artery is proper way of treatment and may need no other surgical procedures.

Chapman, M, Larumbe-Zabala, E, Gosss-Sampson, M, Colpus, M, Triplett, NT, and Naclerio, F. Perceptual, mechanical, and electromyographic responses to different relative loads in the parallel squat. J Strength Cond Res 33(1): 8–16, 2019—The effectiveness of the OMNI-RES (0–10) Scale and the electromyographic signal for monitoring changes in the movement velocity were examined during a set to muscular failure using different percentages of 1 repetition maximum (1RM) in the parallel squat exercise (PSQ). Twelve men (26.3 ± 5.8 years) were evaluated on 8 separate days with 48 hours of rest between sessions. After determining the 1RM value, participants underwent 7 tests until achieving muscular failure with the following percentage ranges: 30 to <40%, 40 to <50%, 50 to <60%, 60 to <70%, 70 to <80%, 80 to <90%, and >90%. An optical rotary encoder measured mean accelerative velocity (MAV), and the OMNI-RES (0–10) Scale was used to express the rating of perceived exertion (RPE) after every repetition of each set. In addition, the normalized root mean square signal of the surface electromyography (N-EMG) was calculated for the vastus medialis muscle. The RPE expressed after the first repetition and when the maximum value of MAV was achieved along the sets was lower (p < 0.001, d > 0.8) than the RPE that corresponded to a 10% drop in MAV and at failure. In addition, the initial RPE was useful to distinguish different loading zones by anchoring the OMNI-RES value to the magnitude of the relative load (<60%, 60 to <70% or ≤70% 1RM). Similar patterns were observed using the N-EMG. In conclusion, apart from differentiating between relative loads during a set to failure in the PSQ, the RPE and the N-EMG can both reflect changes associated with the initial, maximal, 10% drop in movement velocity and the muscular failure.
Cholinergic, But Not Dopaminergic or Noradrenergic, Enhancement Sharpens Visual Spatial Perception in Humans
Authors: Gratton Caterina , Yousef Sahar , Aarts Esther , Wallace Deanna L. , D'Esposito Mark , Silver Michael A.
Published: March 2017

The neuromodulator acetylcholine modulates spatial integration in visual cortex by altering the balance of inputs that generate neuronal receptive fields. These cholinergic effects may provide a neurobiological mechanism underlying the modulation of visual representations by visual spatial attention. However, the consequences of cholinergic enhancement on visuospatial perception in humans are unknown. We conducted two experiments to test whether enhancing cholinergic signaling selectively alters perceptual measures of visuospatial interactions in human subjects. In Experiment 1, a double-blind placebo-controlled pharmacology study, we measured how flanking distractors influenced detection of a small contrast decrement of a peripheral target, as a function of target-flanker distance. We found that cholinergic enhancement with the cholinesterase inhibitor donepezil improved target detection, and modeling suggested that this was mainly due to a narrowing of the extent of facilitatory perceptual spatial interactions. In Experiment 2, we tested whether these effects were selective to the cholinergic system or would also be observed following enhancements of related neuromodulators dopamine or norepinephrine. Unlike cholinergic enhancement, dopamine (bromocriptine) and norepinephrine (guanfacine) manipulations did not improve performance or systematically alter the spatial profile of perceptual interactions between targets and distractors. These findings reveal mechanisms by which cholinergic signaling influences visual spatial interactions in perception and improves processing of a visual target among distractors, effects that are notably similar to those of spatial selective attention.

SIGNIFICANCE STATEMENTAcetylcholine influences how visual cortical neurons integrate signals across space, perhaps providing a neurobiological mechanism for the effects of visual selective attention. However, the influence of cholinergic enhancement on visuospatial perception remains unknown. Here we demonstrate that cholinergic enhancement improves detection of a target flanked by distractors, consistent with sharpened visuospatial perceptual representations. Furthermore, whereas most pharmacological studies focus on a single neurotransmitter, many neuromodulators can have related effects on cognition and perception. Thus, we also demonstrate that enhancing noradrenergic and dopaminergic systems does not systematically improve visuospatial perception or alter its tuning. Our results link visuospatial tuning effects of acetylcholine at the neuronal and perceptual levels and provide insights into the connection between cholinergic signaling and visual attention.
Cued Memory Retrieval Exhibits Reinstatement of High Gamma Power on a Faster Timescale in the Left Temporal Lobe and Prefrontal Cortex

Published: March 2017

Converging evidence suggests that reinstatement of neural activity underlies our ability to successfully retrieve memories. However, the temporal dynamics of reinstatement in the human cortex remain poorly understood. One possibility is that neural activity during memory retrieval, like replay of spiking neurons in the hippocampus, occurs at a faster timescale than during encoding. We tested this hypothesis in 34 participants who performed a verbal episodic memory task while we recorded high gamma (62–100 Hz) activity from subdural electrodes implanted for seizure monitoring. We show that reinstatement of distributed patterns of high gamma activity occurs faster than during encoding. Using a time-warping algorithm, we quantify the timescale of the reinstatement and identify brain regions that show significant timescale differences between encoding and retrieval. Our data suggest that temporally compressed reinstatement of cortical activity is a feature of cued memory retrieval.

SIGNIFICANCE STATEMENTWe show that cued memory retrieval reinstates neural activity on a faster timescale than was present during encoding. Our data therefore provide a link between reinstatement of neural activity in the cortex and spontaneous replay of cortical and hippocampal spiking activity, which also exhibits temporal compression, and suggest that temporal compression may be a universal feature of memory retrieval.
Paraneoplastic endocrine syndromes

Published: March 2017

The majority of neoplasms are responsible for symptoms caused by mass effects to surrounding tissues and/or through the development of metastases. However, occasionally neoplasms, with or without endocrine differentiation, acquire the ability to secrete a variety of bioactive substances or induce immune cross-reactivity with the normal tissues that can lead to the development of characteristic clinical syndromes. These syndromes are named endocrine paraneoplastic syndromes when the specific secretory components (hormones, peptides or cytokines) are unrelated to the anticipated tissue or organ of origin. Endocrine paraneoplastic syndromes can complicate the patient’s clinical course, response to treatment, impact prognosis and even be confused as metastatic spread. These syndromes can precede, occur concomitantly or present at a later stage of tumour development, and along with the secreted substances constitute the biological ‘fingerprint’ of the tumour. Their detection can facilitate early diagnosis of the underlying neoplasia, monitor response to treatment and/or detect early recurrences following successful initial management. Although when associated with tumours of low malignant potential they usually do not affect long-term outcome, in cases of highly malignant tumours, endocrine paraneoplastic syndromes are usually associated with poorer survival outcomes. Recent medical advances have not only improved our understanding of paraneoplastic syndrome pathogenesis in general but also enhanced their diagnosis and treatment. Yet, given the rarity of endocrine paraneoplastic syndromes, there is a paucity of prospective clinical trials to guide management. The development of well-designed prospective multicentre trials remains a priority in the field in order to fully characterise these syndromes and provide evidence-based diagnostic and therapeutic protocols.

Le tableau vivant: Una forma de trasvase entre pintura y cine. El caso de La ronda de noche  (1642) de Rembrandt van Rijn y La ronda de noche (2007) de Peter Greenaway
Authors: Orozco-Abarca Giovanni De J.
Published: March 2017

La presente investigación estudia un punto de encuentro entre el cine y la pintura mediante la representación del tableau vivant en el filme La ronda de noche (Nightwatching, 2007) de Peter Greenaway en relación con el óleo La ronda de noche (Nachwacht, 1642) de Rembrandt van Rijn, con el objetivo de visualizar la configuración de una propuesta estética novedosa en el campo cinematográfico a partir del trasvase de una pieza pictórica hacia el cine, a través de un proceso de cinematización; en dicho proceso, el cine adopta otro tipo de arte, en este caso, la pintura. Para abordar esta relación, se toman como referencia dos conceptos que intervienen directamente en la película La ronda de noche y que denotan el carácter pictórico incorporado en el espacio fílmico para hacer efectivo el tableau vivant; uno de ellos es la temporalidad pictórica y el otro término es el de efecto pintado, mediante los cuales, cinematografía y pintura, fundidas en un plano intermedial, logran un trabajo fílmico novedoso e interdisciplinario.
Poder vestimentario y ley de prohibición del incesto: una lectura foucaultiana del ensayo fotográfico Los intocables del artista Eric Ravelo
Authors: Schroeder Kira
Published: March 2017

Este ensayo es una lectura del proyecto fotográfico Los intocables del artista cubano Eric Ravelo que muestra cuerpos, cuerpos adultos y cuerpos niños, con una particular forma de relacionarse que se nos hace evidente a través de la posición en que se presentan los cuerpos y la forma en que estos cuerpos están ataviados. Estas características exponen ciertas relaciones de poder –poder vestimentario– que ordena los cuerpos y las relaciones entre ellos. En este ensayo se propone que los núcleos de poder-saber evidenciados por Ravelo en su proyecto fotográfico, articulados por el artista como relaciones sacrificiales ordenadas por una cierta forma de vestir los cuerpos, vislumbra una grilla de inteligibilidad donde los núcleos de poder producen espacios de excepción a la ley de prohibición del incesto. Además, argumenta que esta forma de develamiento crítico a través del arte que realiza Ravelo puede pensarse como un acto de un parrhesiasta tal y como lo trabaja Foucault en su libro El coraje de la verdad, entendido como un forma de enunciación de verdad en un acto creador.

Published: March 2017

Este ensayo inicia con una somera exposición teórica sobre la estética del esperpento, la cual fue creada por Ramón del Valle-Inclán para describir los aspectos más grotescos, deformes y monstruosos de la realidad. De igual manera, el esperpento constituye una manera de juzgar el mundo y desenmascarar la vida misma. Este análisis esperpéntico se realiza tomando en cuenta la obra dramática valleinclanesca Divinas palabras (1920).
Foi Carmen Miranda de Antunes Filho y el gesto intercultural
Authors: Funchal Claudia
Published: March 2017

A partir del espectáculo Foi Carmen Miranda (Fue Carmen Miranda) del director brasileño Antunes Filho, este artículo busca una reflexión sobre la interculturalidad del discurso gestual. En esta puesta en escena de Antunes Filho, las culturas de Brasil y de Japón se mezclan, sin que por ello pierdan su identidad,constituyendo una gestualidad mestiza. Utilizando los conceptos de “intercultural” y “mestizaje”, según Gilles Verbunt y Liviu Dospinescu, discutimos cómo los elementos de dos culturas diferentes están presentes simultáneamente en la puesta en escena, poniendo en evidencia su oposición o complementariedad, como a la vez deja una brecha abierta para diferentes interpretaciones, según la referencia cultural del público. Asimismo, relacionamos personajes claves de la cultura brasileña y su gestualidad, con los conceptos de “tiempo del cuerpo” y “tiempo social” en la danza butoh, según Toshiharu Kasai yKate Parsons (2003). Nuestra intención es demostrar que se trata de una puesta en escena intercultural legible desde al menos dos perspectivas, la del público japonés y la del brasileño.

El tercer conceptoconsiste en la muerte, el cual muestra cómo se entendía la vida desde el punto de vista de la muerte.
Is Financial Reporting in the SME Sector Moving towards Transparency? The Evidence from Poland
Authors: Bauer Kinga
Published: March 2017

In the context of the transparency of accounting information, the paper presents new approaches to accounting and financial reporting of enterprises from the SME sector. Therefore, accounting cannot be analysed without the context of particular conditions of individual countries, their social, economic and cultural development. One country – Poland – was selected for the study. The paper is not an in-depth analysis of IFRS for SMEs, Directive 2013/34/ EU and the amended Polish Accounting Act, but only applies to issues directly associated with financial statement transparency. This is a discussion paper that does not unequivocally resolve the matter under consideration, but presents possible approaches and encourages the undertaking of further research.
Dywidenda emocjonalna z inwestycji alternatywnych na przykładzie win francuskich
Authors: Czupryna Marcin , Oleksy Paweł
Published: March 2017

Investing in emotional assets delivers both pecuniary and non-pecuniary benefits to investors. The non-financial component is driven by investor emotions and reflects the cash equivalent of satisfaction from asset ownership.In the paper we examine the non-pecuniary benefits for investors active in the fine wine market by estimating four types of psychic returns. The results reveal lower levels of psychic returns in the case of actively traded fine wines (included in Liv-ex 50) in comparison to older wines with greater significance for investor-collectors (included in Bordeaux Legends 50). In the case of other Liv-ex indices, such regularity cannot be confirmed with available measures, which simultaneously indicates the need to develop new analytical tools and to use desegregated data to quantify emotional dividends.

Wpływ ustawodawstwa amerykańskiego na rozwój rynku ubezpieczeń cybernetycznych w USA
Authors: Strupczewski Grzegorz
Published: March 2017

The aim of the paper is to analyse the role of regulation in stimulating demand for cyber insurance on the example of the US insurance market. This paper adds in-depth comparative analysis of American legislation to the existing scientific achievements, in particular state legislation, in the area of legal responsibility for data breach. This makes it possible to verify the oft-repeated argument that the legislation in the area of personal data security and electronic processing of personal data can stimulate the development of cyber insurance. One of the functions of such insurance is to protect the entity processing personal data from the financial consequences of administrative penalties and third party claims arising from breach of confidentiality. The study shows that state and federal regulations have a clear influence, requiring mandatory notification of data breach, on the development of the cyber insurance market in the US. Therefore, it can be expected that the implementation of similar regulations in the European Union will trigger a positive effect on the European market for cyber-insurance, which is currently in its initial development stage.

ABSTRACT We aimed to investigate whether infants with myelomeningocele would improve their motor ability and functional independence after ten sessions of physical therapy and compare the outcomes of conventional physical therapy (CPT) to a physical therapy program based on reflex stimulation (RPT). Twelve children were allocated to CPT (n = 6, age 18.3 months) or RPT (n = 6, age 18.2 months). The RPT involved proprioceptive neuromuscular facilitation. Children were assessed with the Gross Motor Function Measure and the Pediatric Evaluation of Disability Inventory before and after treatment. Mann-Whitney tests compared the improvement on the two scales of CPT versus RPT and the Wilcoxon test compared CPT to RPT (before vs. after treatment). Possible correlations between the two scales were tested with Spearman correlation coefficients. Both groups showed improvement on self-care and mobility domains of both scales. There were no differences between the groups, before, or after intervention. The CPT and RPT showed similar results after ten weeks of treatment.

Abstract: This study aimed to establish the frequency and spatial distribution of animal and object hoarding in Curitiba (Paraná State), the eighth most populous city in Brazil. All hoarding complaints received by the City Secretaries of Health, Environment and Social Assistance between September 2013 and April 2015 were collected (n = 226) and suspicious cases were individually investigated. A total of 113/226 (50%) of complaints were confirmed as hoarding cases, representing an overall ratio of 6.45 cases per 100,000 inhabitants in Curitiba, of which 48/113 (42.5%) involved object hoarders, 41/113 (36.3%) animal hoarders and 24/113 (21.2%) both animal and object hoarders. A correlation of total identified cases with neighborhood population density and all population stratums analyzed (total, gender, age) was significantly positive (p < 0.01), and with neighborhood mean monthly income (r = -0.2; p = 0.03) significantly negative. A spatial cluster of cases was found in the north of the city (OR = 8.57; p < 0.01). Hoarding cases were relatively frequent in Curitiba and were associated with population distribution patterns and inversely related to neighborhood income.

O diabetes mellitus tipo 2 se destaca, atualmente, na composição dos indicadores dos Estudos de Carga Global de Doença. Este estudo estimou a carga de doença atribuível ao diabetes mellitus tipo 2 e suas complicações crônicas no Brasil, 2008. Foram calculados os anos de vida perdidos ajustados por incapacidade (DALY), anos de vida perdidos por morte prematura (YLL) e os anos de vida perdidos por conta da incapacidade (YLD) estratificados por sexo, faixa etária e região. O diabetes mellitus tipo 2 representou 5% da carga de doença no Brasil, posicionando-se como a 3ª causa mais importante nas mulheres e a 6ª nos homens na construção do DALY. A maioria do DALY se concentrou na faixa etária entre 30 e 59 anos e foi representado majoritariamente pelo YLD. As maiores taxas de YLL e YLD se concentraram nas regiões Nordeste e Sul, respectivamente. As complicações crônicas do diabetes mellitus tipo 2 representaram 80% do YLD. O diabetes mellitus tipo 2 representou um dos principais agravos de saúde no Brasil em 2008, contribuindo com relevantes parcelas de mortalidade e morbidade.

Published: March 2017

RESUMO O estudo avaliou o efeito de treino cumulativo de relações condicionais sobre a aprendizagem de rudimentos de leitura musical. Os estímulos foram sequências de notas nas modalidades: sonora (A), notação em clave de sol (B) e figura de teclado (C). Cinco estudantes universitários realizaram a Condição Não Cumulativa, composta por treinos AB e BC e testes, com dois exemplares diferentes em cada fase experimental. Na Condição Cumulativa, outros cinco participantes aprenderam as relações condicionais com os exemplares da Fase 2 acumulados aos da Fase 1. A Condição Cumulativa mostrou a manutenção de um número significativamente maior de relações AB, desempenhos superiores nos testes de formação de classes de estímulos equivalentes e escores mais elevados de leitura recombinativa do que a Condição Não Cumulativa.
O campo da resolução negociada de conflito: o apelo ao consenso e o risco do esvaziamento do debate político
Authors: Viégas Rodrigo Nuñez
Published: March 2017

Resumo Neste artigo, empreende-se uma genealogia do campo da resolução negociada de conflito e sua disseminação em diferentes áreas, identificando seus discursos e práticas. Buscou-se especificamente evidenciar que a formação deste campo inscreve-se em um processo de reconfiguração do sistema político-econômico capitalista desde os períodos de guerra, no final do século XIX e início do século XX, até mais recentemente, nos contornos do período de “pós-democracia consensual”. Notadamente nesse último período, refletiu-se acerca da possibilidade de que o sentido de tais discursos e práticas seja, sobretudo, o de esvaziar o debate político ampliado, por meio de um apelo ao consenso, que limita ou impede o exercício da reflexão e discussão para a politização de problemáticas que afetam a vida coletiva.
Será a Nigéria um Estado falhado? O grupo Boko Haram
Authors: Cierco Teresa , Belo António
Published: March 2017

Resumo A atual situação na Nigéria motiva uma reflexão sobre o Estado e as funções que este desempenha na sociedade. O incremento do fundamentalismo islâmico no país surge em um contexto de problemas estruturais complexos que colocam em causa a autoridade e a legitimidade do Estado. A evidente fragilidade das instituições e a fraca resposta por parte do Estado à instabilidade e à insegurança provocada por grupos extremistas como o Boko Haram, leva-nos a questionar se a Nigéria poderá ser considerada um Estado falhado. E, tratando-se de um Estado falhado em que a segurança interna é deficitária e os conflitos interétnicos proliferam, estará a unidade nacional comprometida ou seriamente ameaçada? Neste artigo tentamos aferir, por um lado, até que ponto o fundamentalismo islâmico tem afetado o desenvolvimento econômico e humano na Nigéria e, por outro, como o governo tem lidado com esse problema.
Foucault e a racionalidade (neo)liberal
Authors: Avelino Nildo
Published: March 2017

Resumo O artigo aborda o debate em torno da reflexão de Michel Foucault acerca do liberalismo e do neoliberalismo. Apresenta de maneira critica alguns trabalhos recentes, na França e nos EUA, que têm concluído sobre a existência de afinidades, especialmente teóricas, entre Foucault e o neoliberalismo, apontando suas fragilidades metodológicas. Procura, em seguida, evidenciar a especificidade genealógica que caracteriza a análise foucaultiana em relação às abordagens concernidas com a denúncia ideológica ou com a valorização ideal do liberalismo. Retoma particularmente os estudos da governamentalidade a partir dos quais Foucault realizou uma descrição histórica do liberalismo e do neoliberalismo em termos de racionalidade governamental. Apresenta-se um quadro sintético da economia de poder liberal na análise foucaultiana em que se verifica a superposição de três racionalidades historicamente localizáveis: razão de Estado, poder pastoral, biopoder. O artigo termina com uma leitura das diferenças entre o liberalismo econômico e o neoliberalismo e as implicações de cada um deles no exercício do poder político.
Juventud Rural: factores que influyen en el desarrollo de la actividad agropecuaria. Reflexiones sobre el caso argentino

Published: March 2017

Resumen: El éxodo o la permanencia de los jóvenes en el medio rural es un tema sumamente discutido en América Latina. Este trabajo pretende contribuir a esta discusión sobre la base de una investigación empírica realizada a 400 jóvenes en Argentina, en la cual se muestran cómo influyen diferentes variables en el mantenimiento de los jóvenes en el medio rural realizando actividades agropecuarias. La hipótesis que se plantea y que finalmente se valida es que la pertenencia a familias productoras agropecuarias y la continuidad de estudios vinculados a la actividad agropecuaria son los factores claves que permiten mantener a los jóvenes en el medio rural realizando actividades agropecuarias. Las técnicas estadísticas utilizadas para realizar el análisis descriptivo son tablas de contingencia y comparación de medias, en tanto la regresión logística binaria múltiple se utiliza para realizar el análisis de dependencia y validar la hipótesis planteada.

Resumo: A avicultura de corte é uma importante fonte de proteína para a alimentação humana. A compreensão do relacionamento interorganizacional neste ambiente é primordial para a redução de custos operacionais e de transação. Este trabalho objetiva construir um modelo multicritério de avaliação do relacionamento entre uma agroindústria e seus produtores integrados, em Seara, Santa Catarina, Brasil, avaliando-se os possíveis reflexos sobre a competitividade da cadeia de suprimentos. Realizou-se um estudo de caso tendo como enfoque teórico a gestão da cadeia de suprimentos, complementada pela abordagem economia dos custos de transação e das estratégias competitivas. A pesquisa foi quanti-qualitativa e utilizou-se da metodologia de análise multicritério de apoio à decisão construtivista (MCDA-C) para elaboração e interpretação do modelo. Realizaram-se entrevistas com produtores rurais, representantes da agroindústria e especialistas da avicultura. Os agentes definiram custo de produção, remuneração, fatores de produção, risco de investimento, fluxo de informação e ambiente institucional como os pontos de vista fundamentais (PVF) do modelo. Com a aplicação do modelo em três classes de produtores rurais, os PVFs remuneração, risco de investimento, fluxo de informação a jusante da cadeia de suprimentos e custo de produção apresentaram maior impacto no relacionamento interorganizacional para se atingir a competitividade na cadeia.

ABSTRACT Subcutaneous mass was found in ICR mouse during daily health observation in the breeding colony of the National Laboratory Animal Center, Mahidol University, Thailand. The animal was subsequently culled and humanely sacrificed due to the institutional preventive medicine policy. Microbiological and histopathological studies were performed for definitive diagnosis. The results described that the case was subcutaneous abscess and chronic dermatitis in association with Staphylococcus sciuri infection without epizootic and mortality. This was determined as the first reported case in Thailand occurring in mouse. Reproductive stress and abrasion skin wound may be the predisposing factors. Although pathogenic staphylococci in laboratory animals are limited to S. aureus and S. xylosus, S. sciuri opportunistic properties, natural history, and heterogeneity should not be forgotten.

ABSTRACT A 20-year-old unneutered male poodle presented prostration, apathy, staggering gait, lack of appetite and tick infestation. The dog was diagnosed with a Sertoli cell tumor in an undescended testicle by cytological, histopathological and immunohistochemical tests. Pancytopenia with moderate nonregenerative anemia, leukopenia and severe thrombocytopenia were detected in the complete blood count. Cytological and histopathological evaluation of the bone marrow revealed a cellularity of 30%, with erythroid (59%), lymphoid (40%) and mast cells (1%), and an absence of granulocytic, monocytic and megakaryocytic lineage cells. In post-mortem examinations, changes related to hemostatic disorders were found. The absence of microorganisms in molecular tests and an estrogen serum concentration over reference values confirmed hyperestrogenism as a possible cause of pancytopenia. The literature describes a Sertoli cell tumor hyperestrogenism that induced pancytopenia, along with bone marrow hypoplasia of all hematopoietic lineages. In contrast, in the present case, the erythroid precursor cells were preserved in the bone marrow, although there were no reticulocytes circulating in the blood. This case, therefore, should be considered in future investigations of pancytopenia induced by Sertoli cell tumor hyperestrogenism.

ABSTRACT Hypoxemia is a major complication of field anesthesia and no studies regarding this occurrence in mules has been done. Thus, the aim of this study was to evaluate intranasal oxygen supplementation (IOS) in mules (Equus caballus x Equus asinus) anesthetized with ketamine/butorphanol/guaifenesin combination. For this, we used six male, adult mules (322±29kg) which underwent premedication (MPA) with 0.2mg/kg of midazolam intramuscularly after 15 minutes, 0.02mg/kg detomidine IV 5 minutes after, induction IV with combination of ketamine (2mg/mL), butorphanol (22.5mg/mL), and guaifenesin (50mg/mL) (K/B/G) until lateral decumbency. Maintenance was done with the same anesthetic combination. The animals were submitted twice to the protocol described above, 20 days apart, forming two groups. CG: MPA, induction (0.92±0.24mL/kg (mean±SD)), and maintenance (2.2±0.2mL/kg/h) without SIO; TG: MPA, induction (0.98±0.17mL/kg), and maintenance (2.3±0.4mL/kg/h) with IOS flow 40mL/kg/h. During anesthesia arterial blood was collected every 20 minutes (T0, T20, T40, and T60) for blood gas analysis. Data analyzed by ANOVA followed by the Bonferroni test. P<0.05 was considered significant. Hypoxemia of the animals in the CG in periods (59±5; 55±5; 53±7; 49±8) with lower averages than the TG (160±4, 115±34, 92±25, 81±19) was observed, demonstrating that IOS increases PaO2 avoiding the occurrence of hypoxemia.

RESUMO Características produtivas e nutricionais de Brachiaria decumbens, submetida a condições de sombreamento (sol pleno, 20% e 70% de sombreamento), sem e com uso de fertilização (80 kg.ha-1 de N e K2O e 60 kg.ha-1 de P2O5), foram avaliadas no delineamento de blocos casualizados, com quatro repetições. As parcelas sombreadas foram alocadas em um sistema silvipastoril, enquanto aquelas a pleno sol foram avaliadas em um monocultivo de B. decumbens. O sombreamento severo promoveu reduções de 54% na massa seca verde, 59% na massa seca total e 58% na densidade volumétrica de forragem. Aumentos da massa de forragem e da densidade volumétrica em resposta ao fertilizante foram observados somente nas condições de sol pleno e sombreamento moderado. A adubação não influenciou nas características nutricionais da forragem, mas o sombreamento severo promoveu aumentos de 20 e 51% nos teores de clorofila e de proteína bruta, respectivamente. Reduções dos teores de fibra em detergente neutro e fibra em detergente ácido foram observadas com o sombreamento. Os teores de lignina e a digestibilidade in vitro da matéria seca não variaram com nenhum fator estudado (médias de 6,0 e 60,9%, respectivamente). A adubação de B. decumbens com dose moderada de NPK é recomendada para dosséis cultivados no sol pleno e sombreamento moderado, mas deve ser evitada em pastos severamente sombreados, pois não reflete aumento de massa de forragem nem melhorias de seu valor nutricional.

Summary Objective: The aim was to evaluate the effectiveness of the experimental synergists muscle ablation model to promote muscle hypertrophy, determine the period of greatest hypertrophy and its influence on muscle fiber types and determine differences in bilateral and unilateral removal to reduce the number of animals used in this model. Method: Following the application of the eligibility criteria for the mechanical overload of the plantar muscle in rats, nineteen papers were included in the review. Results: The results reveal a greatest hypertrophy occurring between days 12 and 15, and based on the findings, synergist muscle ablation is an efficient model for achieving rapid hypertrophy and the contralateral limb can be used as there was no difference between unilateral and bilateral surgery, which reduces the number of animals used in this model. Conclusion: This model differs from other overload models (exercise and training) regarding the characteristics involved in the hypertrophy process (acute) and result in a chronic muscle adaptation with selective regulation and modification of fast-twitch fibers in skeletal muscle. This is an efficient and rapid model for compensatory hypertrophy.

Resumo O objetivo deste estudo foi analisar representações sociais atribuídas à aposentadoria por servidores públicos federais, identificando os aspectos mais enfatizados e suas implicações no processo de decisão trabalho-aposentadoria. Trata-se de uma pesquisa qualitativa, de caráter exploratório e descritivo, realizada com 283 servidores que já faziam jus à aposentadoria ou se encontravam próximos (menos de 05 anos). Os dados coletados foram distribuídos em dois corpora: aposentadoria e expectativas. A análise lexicográfica foi realizada pela técnica de classificação hierárquica descendente, com o auxílio de um software de análise textual. Os resultados indicam a existência de padrões de significados de aposentadoria entre os sujeitos, estando a intenção de aposentar-se vinculada à ideia de usufruir o tempo e viver com mais qualidade, e o adiamento em resposta ao sentir-se atuante no trabalho, não ter atividades substitutivas, e enquanto estratégia contra a ociosidade.
