 Background: Changes in load during asymmetric holding may be associated with particularly high risk of loss of balance and spinal injury. Therefore, in order to assess occupational lesions and to make preventive rehabilitation programs in such conditions like holding dynamic loads in asymmetric postures could be important.  Methods:  In a cross-sectional study, COP amplitude and velocit...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

conclusions the lack of difference between adma levels in patients with pa and eh suggests that endothelial dysfunction is more likely related to hypertension per se than to the specific etiology of elevated blood pressure. results patients with pa had significantly higher concentrations of adma than healthy controls (0.488 ± 0.085 vs. 0.433 ± 0.053 μmol/l, p = 0.027). no difference was found i...

abstract background: increase in nitric oxide (no) concentration accompanied by alteration in peritoneal immune defense reactions is involved in the pathogenesis of endometriosis. asymmetric dimethylarginine is an endogenous competitive inhibitor of no synthase. this study was designed to compare no metabolite (nitrite), asymmetric dimethylarginine, and estradiol concentrations in serum and per...

The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...

We propose and demonstrate a simple method to generate ultrawideband (UWB) pulses in the optical domain using a chirped intensity modulator and an asymmetric Mach-Zehnder interferometer (AMZI). Polarity- and shape-switchable UWB Gaussian monocycle, doublet, and triplet pulses with fractional bandwidths of 158%, 134%, and 100% and center frequencies of 6.52, 9.78, and 10.1 GHz are experimentally...

in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...
