INTRODUCTION: Lower limb strength has never been characterized separately for late-onset and adult Myotonic Dystrophy Type 1 (DM1) phenotypes. METHODS: The purpose was to: 1) describe and compare lower limb strength between the 2 DM1 phenotypes, and 2) compare the impairment profiles obtained from 2 assessment methods [manual (MMT) and quantitative (QMT) muscle testing], among 107 patients. RESULTS: Both MMT and QMT showed more pronounced weakness in the adult phenotype...

Comprehensive characterization of exposure media used in toxicology studies is still an area of significant divergence when evaluating potential oil spill impacts. When preparing exposure media used for toxicology testing, small variations in simple parameters such as mixing energy, oil type and loading can significantly affect the concentration of the oil components to which test organisms are exposed. The key goal of this study was compare and contrast the physical and chemical compositions of oil water mixtures prepared using fresh and weathered Macondo-related oils under different conditions of mixing and in the presence/absence of chemical dispersants...

We investigated if carbohydrate (CHO) availability could affect the excess post-exercise oxygen consumption (EPOC) after a single supramaximal exercise bout. Five physically active men cycled at 115% of peak oxygen uptake (V̇O2 peak) until exhaustion with low or high pre-exercise CHO availability. The endogenous CHO stores were manipulated by performing a glycogen-depletion exercise protocol 48 h before the trial, followed by 48 h consuming either a low- (10% CHO) or a high-CHO (80% CHO) diet regime. Compared to the low-CHO diet, the high-CHO diet increased time to exhaustion (3...

Chronic exposure to cigarette smoke seems to be related to an increase of pro-inflammatory cytokines, oxidative stress and changes in muscular and physical performances of healthy smokers. However, these parameters have not yet been evaluated simultaneously in previous studies. The participants of this study were healthy males divided into two groups: smokers (n=20) and non-smokers (n=20). Inflammation was evaluated by measuring plasma levels of the cytokines IL-10, IL-6 e TNF-α, and of the soluble receptors sTNFR1 and sTNFR2...

Hearing loss among children, particularly those with severe and profound hearing impairment, has an effect on their communication and development, which in turn can have a significant impact on their parents. This study aimed to evaluate the quality of life of parents of children with hearing loss and identify the associated factors. A cross-sectional study was carried out involving parents of children that went through phonoaudiological therapy at a public university clinic in the city of São Paulo. The research instruments used were: the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-bref), the Social Support Questionnaire 6 (SSQ-6) and the General Health Questionnaire (GHQ-12)...

The aim of the study was to comprehend how the age group and the severity of the motor impairment of children with cerebral palsy modify the mothers' experiences of stress and to understand the coping strategies they use. A qualitative approach was used, with the method framed on Grounded Theory Analysis. Nineteen mothers of children and adolescents with different degrees of motor impairment participated in individual semi-structured interviews. A lack of support and increased time and effort invested in parenting, at the cost of other areas of life threaten participants' physical and emotional health...

This study correlated the impact of Acquired Brain Injury (ABI) on the labor activity of individuals of working age on their quality of life (QOL) and that of their relatives/caregivers. It involved qualitative (content analysis) and quantitative (descriptive) research. Forty-eight individuals with ABI and 27 relatives/caregivers were interviewed. The correlation of the International Classification of Functioning, Disability and Health (ICF) and the World Health Organization Quality of Life WHOQOL-BREF (52...

Delays are ubiquitous in biological systems, ranging from genetic regulatory networks and synaptic conductances, to predator/pray population interactions. The evidence is mounting, not only to the presence of delays as physical constraints in signal propagation speed, but also to their functional role in providing dynamical diversity to the systems that comprise them. The latter observation in biological systems inspired the recent development of a computational architecture that harnesses this dynamical diversity, by delay-coupling a single nonlinear element to itself...

OBJECTIVES: This study examines changes in functional and activity limitations 1998-2012 for individuals 55-69. METHODS: Logistic models are used to estimate trends in limitations in vision, hearing, physical and cognitive functioning, IADLs, and ADLs. Additional models assess the extent to which trends are associated with and differ by education, smoking, and BMI. RESULTS: Changes in prevalence of limitations in vision, hearing, cognitive functioning, and ADLs are not statistically significant...

Two stimuli alternately presented at different locations can evoke a percept of a stimulus continuously moving between the two locations. The neural mechanism underlying this apparent motion (AM) is thought to be increased activation of primary visual cortex (V1) neurons tuned to locations along the AM path, although evidence remains inconclusive. AM masking, which refers to the reduced detectability of stimuli along the AM path, has been taken as evidence for AM-related V1 activation. AM-induced neural responses are thought to interfere with responses to physical stimuli along the path and as such impair the perception of these stimuli...
