OBJECTIVE On May 1, 1996, Ontario, Canada, amended the Liquor Licence Act to extend the hours of alcohol sales and service in licensed establishments from 1 am to 2 am. The purpose of this study was to evaluate the impact of extended drinking hours in Ontario on motor-vehicle collision (MVC) and other injuries admitted to regional trauma units based on Ontario Trauma Registry data. METHOD A q...
Because some of the decline in strength with age may be explained by an impairment of muscle activation, the purpose of this study was to determine the activation level achieved in biceps brachii by older adults during a maximum voluntary contraction (MVC). This capability was assessed with two superimposition techniques: one calculated the activation level that was achieved during an MVC, and ...
Alternate muscle activity between synergist muscles has been demonstrated during low-level sustained contractions [< or =5% of maximal voluntary contraction (MVC) force]. To determine the functional significance of the alternate muscle activity, the association between the frequency of alternate muscle activity during a low-level sustained knee extension and the reduction in knee extension MVC ...
To determine quantitatively the features of alternate muscle activity between knee extensor synergists during low-level prolonged contraction, a surface electromyogram (EMG) was recorded from the rectus femoris (RF), vastus lateralis (VL), and vastus medialis (VM) in 11 subjects during isometric knee extension exercise at 2.5% of maximal voluntary contraction (MVC) for 60 min (experiment 1). Fu...
The objective of this study was to establish the effect of moderate intensity endurance training on muscle strength in relation to hormonal changes in the body. Fifteen young, healthy men took part in 5 week endurance training performed on a cycloergometer. Before and after training program, exercise testing sessions were performed involving all participants. Training program significantly incr...
The Δ32-CCR5 deletion of the CCR5 receptor is protective toward coronary artery pathology and myocardial infarction. Maraviroc (MVC), a CCR5 antagonist, was recently introduced in the therapy of HIV infection; we evaluated whether this drug could modulate the atherosclerotic burden in aviremic PI-treated HIV-positive individuals who underwent MVC intensification. Thus, the effect of MVC on inti...
OBJECTIVES Nearly 20 percent of New York City's (NYC) accidental deaths are related to motor vehicles crashes (MVCs). Detailed International Classification of Disease (ICD-10; World Health Organization [WHO] 2007) cause-of-death coding of MVC-related fatalities improves surveillance and resulting identification of prevention strategies. We investigated ICD-10 codes in these fatalities and the p...
This paper presents (structurally stable) pole-free control designs for minimum variance control (MVC) and generalized minimum variance control (GMVC). For MVC, the authors’ general approach to pole-free design, that is the Smith-factorization approach, is advocated. For GMVC, a numerical optimization procedure is used in order to minimize the sum of modules of all poles of the closed-loop GMVC...
STUDY OBJECTIVE We examined the association between driver restraint use and child emergency department (ED) evaluation following a motor vehicle crash (MVC). METHODS This cohort study included child passengers aged 0-12 years riding with an adult driver aged 21 years or older involved in a MVC in Utah from 1999 to 2004. The 6 years of Utah MVC records were probabilistically linked to statewi...
BACKGROUND Persistent musculoskeletal pain and psychological sequelae following minor motor vehicle collision (MVC) are common problems with a large economic cost. Prospective studies of pain following MVC have demonstrated that demographic characteristics, including female gender and low education level, and psychological characteristics, including high pre-collision anxiety, are independent p...
