Functional magnetic resonance imaging (fMRI) studies involving alcohol challenge are important for identifying neural correlates of alcohol's psychopharmacological effects. However, evaluating acute alcohol effects on blood oxygen level-dependent (BOLD) signal change is complicated by alcohol-related increases in cerebral blood flow (CBF). The present study aimed to further characterize acute alcohol ...

Smoking cessation results in withdrawal symptoms such as craving and negative mood that may contribute to lapse and relapse. Little is known regarding whether these symptoms are associated with the nicotine or non-nicotine components of cigarette smoke. Using arterial spin labeling, we measured resting-state cerebral blood flow in twenty-nine adult ...

Alcohol increases the risk of injuring oneself and others. However, following an injury there appears to be a benefit to alcohol in mediating the body's response to a traumatic injury and reducing mortality. The physiological mechanism underlying this reported association is poorly understood. One approach to explaining the pathways by ...

It has been suggested that smoking asthmatics benefit less from corticosteroid treatment than never-smoking asthmatics. We investigated differences in blood and sputum inflammatory profiles between ex-, current-, and never-smokers and assessed their ICS treatment response after 2-week and 1-year treatment. We analyzed FEV1, PC20 methacholine and PC20 AMP, (differential) cell ...

Acetaldehyde is a strongly electrophilic compound that is endogenously produced as a first intermediate in oxidative ethanol metabolism. Its high reactivity towards biogenic nucleophiles has toxicity as a consequence. Acetaldehyde readily undergoes a non-enzymatic condensation reaction and consecutive ring formation with cysteine to form 2-methylthiazolidine-4-carboxylic acid (MTCA). For analytical purposes, ...
