Immobilization-related skeletal muscle atrophy is a major concern to patients in Intensive Care Units and it has a profound effect on the quality of life. However, the underlying molecular events for the therapeutic effect of electroacupuncture to treat muscle atrophy have not been fully elucidated. Here we developed an immobilization mouse model and tested the hypothesis that skeletal muscle weakness may be caused by the increased expression of γ and α7 nicotinic acetylcholine receptors (nAChRs) on muscle cell membranes, while electroacupuncture could decrease the expression of γ and α7 nicotinic acetylcholine receptors...

Epidemiological studies report strong association between mood disorders and tobacco addiction. This high comorbidity requires adequate treatment but the underlying mechanisms are unknown. We demonstrate that nicotine exposure, independent of drug withdrawal effects, increases stress sensitivity, a major risk factor in mood disorders. Nicotine and stress concur to induce long-lasting cellular adaptations within the dopamine (DA) system. This interplay is underpinned by marked remodeling of nicotinic systems, causing increased ventral tegmental area (VTA) DA neurons' activity and stress-related behaviors, such as social aversion...

Maternal nicotine (NIC) exposure causes overweight, hyperleptinemia and metabolic disorders in adult offspring. Our study aims to explore the underlying mechanism of perinatal NIC exposure increases obesity susceptibility in adult female rat offspring. In our model, we found that adult NIC-exposed females presented higher body weight and subcutaneous and visceral fat mass, as well as larger adipocytes, while no change was found in food intake. Serum profile showed a higher serum glucose, insulin and leptin levels in NIC-exposed females...

Studies on the cognitive working mechanism of smoking cessation in high-risk populations are few and much needed, and identifying long-term psychosocial factors to smoking cessation are relevant to improve intervention for cardiac patient groups. This longitudinal study followed patients who smoked and suffered an acute coronary syndrome from hospitalization to 12 months after clinical discharge. Questionnaires were administered to assess nicotine dependence, behavioral dependence, autonomous self-regulation, perceived competence, social support, anxiety, depressive symptoms and meaning in life at baseline, six months and twelve months after clinical discharge...

BACKGROUND: India is the world's second largest consumer of tobacco, but tobacco cessation remains uncommon due, at least in part, to underutilization of cessation pharmacotherapy. We evaluated the availability, sales, and affordability of nicotine replacement therapy, bupropion, and varenicline in the South Indian state of Kerala to understand potential reasons for underutilization. METHODS AND RESULTS: From November 2016 to April 2017, we collected data on availability, inventory, and pricing of cessation medication through a cross-sectional survey of 199 public, semiprivate (Karunya), and private pharmacies across 5 districts in Kerala using World Health Organization/Health Action International methodology...

BACKGROUND: Evidence concerning the impact of vaping on respiratory infections remains contradictory. Cell and animal studies suggested that vaping may increase vulnerability to respiratory infections, but human data do not confirm this concern. CASE PRESENTATION: We present a case of a never-smoker who became a vaper and after a few months of e-cigarette use experienced a complete resolution of chronic tonsillitis and a marked improvement in tonsilloliths. CONCLUSIONS: As this is a never-smoker, the improvements cannot be attributed to smoking cessation...

The bispyridinium compound MB327 has been shown previously to have a positive pharmacological effect against poisoning with organophosphorous compounds (OPCs). The mechanism by which it exerts its therapeutic effect seems to be directly mediated by the nicotinic acetylcholine receptor (nAChR). In the present study, the development of mass spectrometry based binding assays (MS Binding Assays) for characterization of the binding site of MB327 at the nAChR from Torpedo californica is described. MS Binding Assays follow the principle of radioligand binding assays, but do not, in contrast to the latter, require a radiolabeled reporter ligand, as the readout is in this case based on mass spectrometric detection...

BACKGROUND: Cigarette smoking is 5 times more prevalent among homeless individuals than in the general population, and homeless individuals are disproportionately affected by smoking-related morbidity and mortality. Homeless smokers report interest in changing their smoking behavior; however, established smoking cessation interventions are neither desirable to nor highly effective for most members of this population. The aim of this study was to document homeless smokers' perceptions of established smoking interventions as well as self-generated, alternative smoking interventions to elucidate points for intervention enhancement...

BACKGROUND: Studies show that repeated nicotine use associates with high alcohol consumption in humans, and that nicotine exposure sometimes increases alcohol consumption in animal models. However, the relative roles of genetic predisposition to high alcohol consumption, the alcohol drinking patterns, and the timing of nicotine exposure both with respect to alcohol drinking and developmental stage remain unclear. The studies here manipulated all these variables, using mice selectively bred for differences in free-choice alcohol consumption to elucidate the role of genetics and nicotine exposure in alcohol consumption behaviors...

RATIONALE: Individuals with depression smoke more than smokers without depression. Research has shown that cigarette demand is a useful tool for quantifying tobacco reinforcement and supposes a clinical predictor of treatment outcomes. Despite previous studies examining the relative reinforcing efficacy of nicotine among different populations of smokers, to date, no study has assessed cigarette demand among individuals with elevated depressive symptoms. OBJECTIVE: The aim of this study was to compare cigarette demand among samples of smokers with low and elevated depressive symptoms...
