Low back pain and degenerative disc disease are a significant cause of pain and disability worldwide. Advances in regenerative medicine and cell-based therapies, particularly the transplantation of mesenchymal stem cells and intervertebral disc chondrocytes, have led to the publication of numerous studies and clinical trials utilising these biological therapies to treat degenerative spinal cond...

In order to achieve the highly efficient and accurate identification of fracture modes including tension or shear fractures during rock failure, an intelligent method based on Wigner-Ville distribution (WVD) spectrogram features acoustic emission (AE) signals was proposed. This mainly constructed by following steps: Firstly, AE hits corre-sponding were obtained through conducting Brazilian disc...

A new tree frog species of the genus Scinax from the interfluve between the Purus and Madeira rivers, Brazilian Amazonia, is described and illustrated. The new species is diagnosed by medium body size, snout truncate in dorsal view, ulnar and tarsal tubercles absent, nuptial pads poorly developed, skin on dorsum shagreen, dorsum light brown with dark brown spots and markings, white groin with b...

This paper presents a step towards the design of a novel test for simultaneous identification of all the stiffness components of orthotropic composite materials. A simulator was adopted to numerically simulate the whole identification process. Synthetic images were generated and then processed by Digital Image Correlation (DIC) to calculate the strain fields. The Virtual Fields Method (VFM) was...

Up until now, there have been few studies of the helminth fauna of Brazilian populations of Pogonias cromis. In North America, P. cromis is known to be a definitive host of Cotylogaster basiri, although there have been no reports of any species of Cotylogaster infecting fish in Brazil. During necropsies of marine fish obtained from professional fisherman in the state of Rio Grande do Sul, Brazi...

Brazilian immigrants comprise the third largest ethnic group within the Japanese population. The aim of this cross-sectional study was to determine the factors associated with the prevalence of dental caries in Brazilian schoolchildren living in Japan. A total of 378 schoolchildren, aged between 6 and 14 years, attending Brazilian schools in Japan were included. Clinical data were collected acc...

The aim of this study was to identify, in bibliographic production, how Brazilian nurses have been discussed "work process" in nursing practice. The bibliographic research was realized in Lilacs, in a period from January of 1993 to December of 2003, and focus the periodics: Acta Paulista de Enfermagem, Nursing (SP), Revista Brasileira de Enfermagem, Revista da Escola de Enfermagem da USP, Revis...

BACKGROUND AND OBJECTIVES Statistical analysis is necessary for adequate evaluation of the original article by the reader allowing him/her to better visualize and comprehend the results. The objective of the present study was to determine the frequency of the adequate use of statistical tests in original articles published in the Revista Brasileira de Anestesiologia from January 2008 to Decembe...

The effect of solid content (2.5-10%, w/v) and temperature (30-70°C) on the viscosity of tapioca meal from three cassava varieties was investigated in this study. Viscosity measurements were conducted using a digital rotational Brookfield viscometer. The viscosity of tapioca meal increased with increasing solid content and decreasing viscometer speeds. An empirical power-law equation fitted the...

Background: The purpose of this study was to identify the effects of eight weeks of conventional and suspension corestability exercises by use of the designed device on characteristic of intervertebral discs in low back pain.Methods: A total of 27 men with chronic low back (CLB) pain due to lumbar disc herniation in L4-L5 and L5-S1 regionswere enrolled in this quasi-experiment...
