Chemical exchange saturation transfer (CEST) imaging is a relatively new magnetic resonance imaging contrast approach in which exogenous or endogenous compounds containing either exchangeable protons or exchangeable molecules are selectively saturated and after transfer of this saturation, detected indirectly through the water signal with enhanced sensitivity. The focus of this review is on bas...

In a report released on 20 November 2002, entitled Action on HIV/AIDS in Prisons: Too Little, Too Late--A Report Card, the Canadian HIV/AIDS Legal Network concluded that despite repeated studies and nearly ten years of recommendations for urgent and pragmatic action, the response of Canadian governments to HIV/AIDS, HCV, and injection drug use in prisons remains inadequate. Only a few weeks lat...

OBJECTIVES We piloted a monitoring mechanism to document police encounters around programs targeting people who inject drugs (PWID), and assessed their demographic predictors at 2 Baltimore, Maryland, needle exchange program (NEP) sites. METHODS In a brief survey, 308 clients quantified, characterized, and sited recent police encounters. Multivariate linear regression determined encounter pre...

Chemical exchange saturation transfer (CEST) is a novel contrast mechanism for magnetic resonance imaging (MRI). CEST MRI selectively saturates exchangeable protons that are transferred to MRI-detectable bulk water signal. MRI-CEST (pH)-responsive agents are probes able to map pH in the microenvironment in which they distribute. To minimize the confounding effects of contrast agent concentratio...

The GLYcan Data Exchange (GLYDE) standard has been developed for the representation of the chemical structures of monosaccharides, glycans and glycoconjugates using a connection table formalism formatted in XML. This format allows structures, including those that do not exist in any database, to be unambiguously represented and shared by diverse computational tools. GLYDE implements a partonomy...

Recently, corporate social responsibility (CSR) is becoming widely recognized as an issue for Japanese companies. Corporate responsibility for employees is considered important by various stakeholders, and occupational safety and health is regarded as one of these responsibilities. The present authors examined this issue from the viewpoint of corporate management by analysis of statements found...

Carter, R. C. and Wilde, P., 1972. Cation exchange capacity of suspended material from coastal sea water off central California. Mar. Geol., 13: 107-122. The cation exchange capacity (CEC) of suspended particles (> 0.5 ~) in sea water is measured by a described methylene blue (MB) absorption method which has the following characteristics: sample volume: minimum of 100 ml sea water; time of meas...

We modified the original design for a rapid solvent exchange (RSE) device with the intent of making the RSE method (i) more efficient and (ii) easier to adopt and implement. Our modifications improved solvent-removal kinetics by a factor of 2, while reducing sample-prep time by a factor of 3. In this paper, we develop the kinetic model that informed the device revision and we address several RS...

The aim of the current study is to investigate the effectiveness of the Turkish corporate governance system. To reach this aim, the paper first discusses the corporate governance system of Turkey briefly. The measures of effectiveness of a corporate governance system are formulated and CEO turnover is used as a measure. The effectiveness of the Turkish corporate governance system is analyzed by...

We find that leverage in exchange traded funds (ETFs) can affect the “crookedness” of volatility smiles. This observation is consistent with the intuition that return shocks are inversely correlated with volatility shocks – resulting in more expensive out-of-the-money put options and less expensive out-of-the-money call options. We show that the prices of options on leveraged and inverse ETFs c...
