Discriminant analysis of neuromuscular variables in chronic low back pain

Background: Investigation and discrimination of neuromuscular variables related to the complex aetiology of low back pain could contribute to clarifying the factors associated with symptoms. Objective: Analysing the discriminative power of neuromuscular variables in low back pain. Methods: This study compared muscle endurance, proprioception and isometric trunk assessments between women with low back pain (LBP, n=14) and a control group (CG, n=14). Multivariate analysis of variance and discriminant analysis of the data were performed. Results: The muscle endurance time (s) was shorter in the LBP group than in the CG (p=0.004) with values of 85.81 (37.79) and 134.25 (43.88), respectively. The peak torque (Nm/kg) for trunk extension was 2.48 (0.69) in the LBP group and 3.56 (0.88) in the GG (p=0.001); for trunk flexion, the mean torque was 1.49 (0.40) in the LBP group and 1.85 (0.39) in the CG (p=0.023). The repositioning error (degrees) before the endurance test was 2.66 (1.36) in the LBP group and 2.41 (1.46) in the CG (p=0.664), and after the endurance test, it was 2.95 (1.94) in the LBP group and 2.00 (1.16) in the CG (p=0.06). Furthermore, the variables showed discrimination between the groups (p=0.007), with 78.6% of the individuals with low back pain correctly classified in the LBP group. In turn, variables related to muscle activation showed no difference in discrimination between the groups (p=0.369). Conclusion: Based on these findings, the clinical management of low back pain should consist of both resistance and strength training, particularly in the extensor muscles.

Inovação científica em estudos medievais: descobrindo os sons do português arcaico

In the context of the confrontation between the several existing possibilities of comprehension of the term “innovation” in the Linguistic fields, the main goal of this paper is to explore the comprehension of this term considering the adoption of new methodologies, based on the analysis of a specific case, of the Research Group Phonology of Portuguese: Archaic and Brazilian periods, which investigates the phonology of a past period of the language from which there are no more alive native speakers.

O legado grego na terminologia gramatical brasileira

This study aims at investigating the existence of a Greek terminological legacy in the Brazilian grammatical organization, taking into account that the initial Greek grammar is the source of our grammar, through the Latin grammar, and that the field defined by it is a reference point for studying the evolution of Western thought about language. The theoretical and methodological approach is based on Historical Linguistics along the lines that guided the extensive research on the emergence of grammar in the West, which is the source of the information organized here (NEVES, 2005). The reflections focus on the examination of nomenclature, considering that it conceptually maps the set of positions assumed, and in general maintained, that deserve consideration. Among other things, the survey compared both Greek terms inherited in the continuous current of the grammatical thinking with Greek terms introduced later, and terms transliterated from the Greek with terms modeled on the Latin translation. In addition, there have been cases of names that were changed while the concept was kept and cases of concepts that were changed while the name was kept. Anyway, the examination of the nomenclature reveals the undeniable existence of a Greek legacy in the organization of the Portuguese grammar.

Epitheliotropic cutaneous T-cell lymphoma associated with melanoma in a dog: case report

Several types of tumors affect dogs' skin. Simultaneously occurring neoplasms with different histological patterns might be rarely present in the same animal. This paper describes the occurrence of epitheliotropic cutaneous T-cell lymphoma and melanoma in a dog. The animal had nodular lesions in the abdominal region and serpiginous plaques on the dorsal region of the trunk. Cytology evidenced malignant fusiform cells from the abdominal lesions as well as few round cells from the dorsal. The histopathological examination of the abdominal lesions showed dermis with polygonal to spindle-shaped neoplastic cells. The lesion of the dorsal region evidenced neoplastic round cells with generally distinct cell borders and a moderate amount of eosinophilic cytoplasm. Abdominal lesions were positive for Melan A. Dorsal and forelimb lesions were positive for CD3. This study reports the occurrence of epitheliotropic cutaneous T-cell lymphoma and malignant melanoma in a crossbred Boxer dog and discusses the importance of performing immunohistochemical profile to confirm the phenotype of the tumor.

Sistemas de retenção O'ring e barra-clipe em overdenture mandibular

The dissatisfaction of the treatment with mandibular complete dentures in edentulous patients has been a constant problem in Dentistry. Often, the absence of stability and retention, resultants of a physiologic condition and alveolar ridge resorption, bring reduction of chewing force, speech problems and social life interference. In these cases, the rehabilitation over osseointegrated implants can be an effective and safe alternative of treatment. When it is not possible to put implants in appropriate number and disposition, it is necessary to make a simple and low costing prosthetic planning, which makes resurge the overdentures. Various implant supported attachment systems for overdentures have been developed in the dental market. Thus, intending to facilitate the professional choice, this study review the literature about attachment systems O’ring and bar- clip in its following aspect: retention level, stress distribution, hygiene complications and patient satisfaction.

As revoltas e seu impacto sobre a comunicação pública: o potencial do Observatório Participativo da Juventude

The Participatório: Observatório Participativo da Juventude (Participatory: Observatory on the Youth Participation) is an online platform created in August 2013 as part of the response of the General Secretariat of the Presidency of the Republic of Brazil to the protests which took Brazilian streets in the middle of that year. This paper analyses the Participatório against the theoretical context brought by studies of digital activism and social movements. We revise relevant theories and present results of an empirical study indicating parameters to assess whether the apparent goals of the platform would have been reached. The data suggest that the initiative could achieve its purposes as long as it secures the efficacy of future improvements.

Redes e ambientes virtuais artísticos

As experimentações com arte e tecnologia vêm-se multiplicando nesses três últimos decênios com a utilização, pelos artistas, de diversas formas de realização, produção e distribuição, possibilidade esta acentuada, em particular, com a popularização da internet nos anos 90 e, mais recentemente, com os dispositivos wireless e ambientes virtuais multiusuário. As novas possibilidades de relação usuários/dispositivos habilitadas pela tecnologia de comunicação mediada por computadores no ambiente de rede proporcionam um espaço de comunicação interativo que permite participar de eventos, experiências de presença e ação à distância explorando a sensação de ubiqüidade, deslocamento e simultaneidade. Este trabalho é sobre realizações e projetos artísticos no dinâmico universo da telemática, expresso na produção contemporânea, com um foco maior na produção artística brasileira

The exponential COM-Poisson distribution

The Conway-Maxwell Poisson (COMP) distribution as an extension of the Poisson distribution is a popular model for analyzing counting data. For the first time, we introduce a new three parameter distribution, so-called the exponential-Conway-Maxwell Poisson (ECOMP) distribution, that contains as sub-models the exponential-geometric and exponential-Poisson distributions proposed by Adamidis and Loukas (Stat Probab Lett 39:35-42, 1998) and KuAY (Comput Stat Data Anal 51:4497-4509, 2007), respectively. The new density function can be expressed as a mixture of exponential density functions. Expansions for moments, moment generating function and some statistical measures are provided. The density function of the order statistics can also be expressed as a mixture of exponential densities. We derive two formulae for the moments of order statistics. The elements of the observed information matrix are provided. Two applications illustrate the usefulness of the new distribution to analyze positive data.
