On the other hand, the level of PRIMA mRNA was not affected after the heat shock. In parallel with AChE(T) mRNA, the enzymatic activity of cellular AChE, in terms of G(1) and G(2) forms, was increased after heat shock: however, the PRIMA-linked G(4) remained unchanged. These results suggest that heat shock can induce the expression level of AChE(T) by the regulation of AChE(T) transcripts in NG108-15 cells. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
“The purpose of this study is to develop statistical
methodology to facilitate indirect estimation of the concentration of antiretroviral drugs and viral Epigenetics inhibitor loads in the prostate gland and the seminal vesicle. The differences in antiretroviral drug concentrations in these organs may lead to suboptimal concentrations in one gland. Suboptimal levels of the antiretroviral drugs may not be able to fully suppress the virus in that gland, leading to a source of sexually transmissible virus and increasing the chance of selecting for a drug-resistant virus. This information may be useful for selecting an antiretroviral drug regimen NVP-BSK805 JAK/STAT inhibitor that will achieve optimal concentrations in the genital tract glands. Using fractionally
collected semen ejaculates, Lundquist (Acta Physiol. Scand. 1949; 19:1-95) measured levels of surrogate markers in each fraction that are uniquely produced by specific male accessory CA3 glands. To determine the original glandular concentrations of the surrogate markers, Lundquist solved a simultaneous series of linear equations. This method has several limitations. In particular, it does not yield a unique solution, it does not address measurement error, and it does not provide population-averaged estimates after taking into account intersubject variability in the parameters.
To cope with these limitations, we developed a mechanistic latent variable model based on the physiology of the male genital tract and surrogate markers. We employ a Bayesian approach and perform a sensitivity analysis on the distributional assumptions on the random effects and priors. The model and Bayesian approach are validated on experimental data where the concentration of a drug should be (biologically) differentially distributed between the two glands. In this example, the Bayesian model-based conclusions are found to be robust to model specification and this hierarchical approach leads to more scientifically valid conclusions than the original methodology. In particular, unlike existing methods, the proposed model-based approach was not affected by a common form of outliers. Copyright (C) 2007 John Wiley & Sons, Ltd.”
“The purpose of this study was to (1) evaluate the mechanical efficiency (ME) of two commercially available lever-propulsion mechanisms for wheelchairs and (2) compare the ME of lever propulsion with hand rim propulsion within the same wheelchair.
