Basic research concerning drug tolerance and withdrawal may inform clinical practice, and vice versa. Three areas that integrate the work of the laboratory and the clinic are discussed: (a) drug overdose, (b) cue exposure treatment of addiction, and (c) pharmacological treatment of withdrawal symptoms. The areas are related in that they indicate the(More)
BACKGROUND Angiotensin-converting enzyme (ACE) inhibitors reduce mortality, myocardial infarction, stroke, heart failure, need for revascularization, nephropathy, and diabetes and its complications. Although angiotensin-II receptor blockers (ARBs) have been less extensively evaluated, theoretically they may have "protective" effects similar to those of ACE(More)
INTRODUCTION Antimuscarinics are the principal pharmacological treatment for overactive bladder (OAB), but frequently give rise to anticholinergic side effects, such as dry mouth, a factor leading to poor persistence. The β3-adrenoceptor agonist mirabegron is devoid of significant anticholinergic activity, while being effective in OAB. We evaluated(More)
This study compares the feature of different media with the combination of selective with non-selective media in a TAL method for recovery of Listeria innocua cells exposed to thermal treatments. Experiments were conducted in broth at constant temperature (52.5 and 65.0 °C) and pH (4.5 and 7.5) conditions, using NaCl or glycerol to adjust water activity to(More)
There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that it should be possible to(More)
Acidification of foods with organic acids, either by fermentation or by intentional addition, is an important and common mechanism for controlling foodborne pathogens in a diversity of food products. The objective of this work was to study thermal inactivation of Listeria innocua, an acid tolerant microorganism, at 52.5, 60.0 and 65.0 degrees C, at(More)

INTRODUCTION This analysis compared the cost-effectiveness of once-daily regimens of mirabegron 50 mg and generic tolterodine ER 4 mg in a hypothetical cohort of previously treated patients with overactive bladder (OAB) in Canada. METHODS A Markov model was developed to represent different health states according to OAB symptoms (frequency, incontinence),(More)
BACKGROUND The β3-adrenoceptor agonist, mirabegron, and antimuscarinic agents provide similar efficacy for the treatment of overactive bladder (OAB), but mirabegron appears to be associated with better persistence, perhaps due to an absence of anticholinergic side-effects. This study estimated the expected costs associated with the management of OAB in(More)
