BACKGROUND In British Columbia, Canada, methadone maintenance treatment formulation transitioned from the oral liquid compound Tang™-flavoured methadone to the ten-times more concentrated cherry-flavoured Methadose™ in February 2014. We quantitatively describe perceptions and reported consequences among a sample of patients on methadone maintenance treatment following this transition. METHODS...

Flash photolysis studies have shown that the membrane lipid environment strongly influences the ability of rhodopsin to form the key metarhodopsin II intermediate. Here we have used plasmon-waveguide resonance (PWR) spectroscopy, an optical method sensitive to both mass and conformation, to probe the effects of lipid composition on conformational changes of rhodopsin induced by light and due to...

So long as a ban is enforceable, large private athletic institutions—such as Major League Baseball and the National Collegiate Athletic Association—should not allow their athletes to take performance-enhancing drugs.The argument I present is game-theoretic: though each athlete prefers unilateral permission to dope over a universal ban, he also prefers a universal ban over universal permission t...

A selection of cellulose pulps was investigated for their chemical changes during the required process steps to viscose dope. The selection of the pulps was based on pulping process, original wood type and intrinsic viscosity. In total, five sulfite pulps and four sulfate pulps were chosen, of which all but one sulfate pulp were of dissolving grades. The physical and chemical properties of the ...

BACKGROUND/AIM Discussions of doping often report Goldman's sensational results that half of the elite athletes asked would take a drug that guaranteed sporting success which would also result in their death in 5 years' time. There has never been any effort to assess the properties of the 'Goldman dilemma' or replicate the results in the post World Anti-Doping Agency context. This research eval...

Cationic lipids are widely used for gene transfection, but their mechanism of action is still poorly understood. To improve this knowledge, a structure-function study was carried out with two pyridinium-based lipid analogs with identical headgroups but differing in alkyl chain (un)saturation, i.e., SAINT-2 (diC18:1) and SAINT-5 (diC18:0). Although both amphiphiles display transfection activity ...
