Aims: Many theoretical perspectives suggest that alcohol-related stimuli bear on attentional processes. Building upon these ideas and recent advances regarding the attention-constricting impact of approach motivational states, we predicted that mere exposure to alcohol-related images would suffice to reduce the breadth of attention among individuals who possessed a strong motivation to consume alcohol.
Design: Two studies exposed participants to alcohol and neutral cues prior to assessing attention structure. In both studies, measures of alcohol use, negative alcohol expectancies, trait approach motivation and alcohol-related approach motivation were assessed.
Setting And Participants: Study 1 comprised 102 undergraduates and study 2 comprised 161 undergraduates. Studies were conducted at Texas A&M University, College Station, Texas.
Measurements: In both studies, participants were briefly exposed to pictures of various stimuli (alcohol versus neutral pictures). After each picture was displayed, participants completed a trial assessing attentional focus.
Findings: After controlling for relevant covariates, both studies demonstrated that exposure to alcohol-related pictures led to a narrowing of attentional focus among individuals who possessed a strong motivation to use alcohol. Exposure to neutral pictures, however, did not interact with alcohol-related motivation to influence attentional focus.
Conclusions: Alcohol cues narrow attentional breadth for individuals who are motivated to consume alcohol, suggesting a non-pharmacological means in which alcohol produces a narrow mindset. Alcohol cues may contribute to cognitive and behavioral deficits, as well as drinking behaviors, in part, because they lead to the inability to process a broad range of information in the environment.

Background: Nondaily smoking is a widespread and increasingly prevalent pattern of use. To date, no effective treatment approach for nondaily smoking has been identified.
Objective: This study aimed to conduct an unblinded randomized controlled trial to evaluate proof-of-concept markers of the Smiling instead of Smoking (SiS) app, a smartphone app for smoking cessation, designed specifically for people who smoke less than daily, within the framework of positive psychology.

Background: Chronic alcohol consumption in alcohol use disorder (AUD) is associated with autonomic nervous system dysregulation, increasing cardiovascular risk, and high alcohol cravings. Heart rate variability (HRV), a marker of autonomic nervous system responsiveness to stressors, may mediate alcohol's impact on the cardiovascular system. While pregnenolone (PREG) has been shown to normalize heart rate and blood pressure in individuals with AUD, its effects on sympathetic and parasympathetic components of HRV and related alcohol craving are not known.

Glycolate oxidase (GOX) is a crucial enzyme of photorespiration involving carbon metabolism and stress responses. It is poorly understood, however, how its activities are modulated in response to oxidative stress elicited by various environmental cues. Analysis of Arabidopsis catalase-defective mutant cat2 revealed that the GOX activities were gradually repressed during the growth, which were accompanied by decreased salicylic acid (SA)-dependent cell death, suggesting photorespiratory HO may entrain negative feedback regulation of GOX in an age-dependent manner.

Aims: Over the recent decades, smoking among women has become an increasingly pressing public health challenge. Mounting evidence suggests that, compared to men, women's smoking is more strongly influenced by habitual responses to sensorimotor cues. To understand the brain mechanisms underlying the cessation challenges commonly reported by women who smoke, the present study used voxel-based morphometry (VBM) to investigate sex-related volumetric differences in the dorsal striatum, a region implicated in habitual substance use behavior, and their associations with self-reported quit interest among daily smoking adults.

The ability of environmental cues to trigger alcohol-seeking behaviours is thought to facilitate problematic alcohol use. Individuals' tendency to attribute incentive salience to cues may increase the risk of addiction. We sought to study the relationship between incentive salience and alcohol addiction using non-preferring rats to model the heterogeneity of human alcohol consumption, investigating both males and females.
