The hand grip forces at the front and rear handles of a chain saw were measured during work, in 89 professional lumberjacks. The symptoms caused by vibration to the upper limbs were compared with the hand grip force (HGF) during work. To allow better comparison between subjects we used the ratio of hand grip force (HGF) to the maximal voluntary compression force (MVC), HGF/MVC expressed as a pe...

Addition of the CCR5 inhibitor Maraviroc (MVC) to ongoing antiretroviral therapy increases CD4+ T cell counts in some virologically suppressed patients with suboptimal CD4+ T cell recovery. To understand the mechanisms by which MVC elicits increases in CD4+ T cell counts, the present study was undertaken to identify host factors (i.e. genes) that are modulated and are correlated with CD4+ T cel...

The purpose of this study was to compare four different methods of normalising electromyograms (EMGs) recorded during normal gait. Comparisons were made between the amplitude, intra-individual variability and inter-individual variability of EMGs. Surface EMGs were recorded from the biceps femoris, semitendinosus, vastus lateralis and vastus medialis of ten males and two females while they walke...

OBJECTIVE Studies exploring the immunologic effects of maraviroc (MVC) have produced mixed results; hence, it remains unclear whether MVC has unique immunologic effects in comparison with other antiretroviral drugs. We sought to determine whether MVC has differential effects compared with tenofovir disoproxil fumarate (TDF) during initial antiretroviral therapy. DESIGN Prospective study in AI...

OBJECTIVE Few data are available about the efficacy of maraviroc (MVC) during routine use. We characterized indications for MVC use and the efficacy of MVC in clinical practice. METHODS Thirty-two patients treated with MVC at our institution between 2006 and 2009 were included. Genotypic (n +/- 31) and phenotypic (n +/- 13) tropism analysis was performed. We determined indications for MVC use...

PURPOSE To determine the most effective electromyographic (EMG) normalization method for cycling fatigue protocols. METHODS Ten healthy subjects performed two 5-s isometric knee extension maximal voluntary contractions (MVC) at a knee joint angle of 60 degrees, two fixed cycle pedal contraction at knee joint angles of 60 degrees (60 degrees A) and 108 degrees (108 degrees A), and a dynamic si...

[Purpose] The aim of this study was to investigate the changes in spinal motor neuron excitability and autonomic nervous system activity during motor imagery of isometric thenar muscle activity at 10% and 50% maximal voluntary contraction (MVC). [Methods] The F-waves and low frequency/high frequency (LF/HF) ratio were recorded at rest, during motor imagery, and post-trial. For motor imagery tri...

Maraviroc (MVC) gels are effective at protecting rhesus macaques from vaginal SHIV transmission, but breakthrough infections can occur. To determine the effects of a vaginal MVC gel on infecting SHIV populations in a macaque model, we analyzed plasma samples from three rhesus macaques that received a MVC vaginal gel (day 0) but became infected after high-dose SHIV-162P3 vaginal challenge. Two i...

BACKGROUND The influence of atrioventricular (AV) interaction on mitral valve closure (MVC) and left ventricular (LV) isovolumic contraction is not fully clarified. We investigated the relationship among AV delay, MVC, and LV isovolumic contraction using a horse model because of the low heart rate and physiologically long AV delay. METHODS AND RESULTS Six horses were evaluated during sinus rh...

Graph-based multi-view clustering (G-MVC) constructs a graphical representation of each view and then fuses them to unified graph for clustering. Though demonstrating promising performance in various applications, we observe that their formulations are usually non-convex, leading local optimum. In this paper, propose novel MVC algorithm termed robust graph-based (RG-MVC) address issue. particul...
