Nicotine replacement therapy (NRT) doubles successful quitting, but more than half of NRT users do not comply with optimal treatment regimens. From the 2005 Colorado state tobacco survey, quit attempters who utilized NRT (N=366) were analyzed in spring 2007. Descriptive and regression analyses were used to examine reasons for discontinuing NRT, length of time on NRT, and quit intentions. The reasons for discontinuing NRT were resuming smoking (34%), side effects (17%), NRT not helping with quitting (14%), quitting smoking (10%), and cost (5%). Poverty, age, and non-Latino minority status were associated with reasons for discontinuation other than quitting smoking. Having side effects was associated with a short duration of NRT use and 95% lower odds of intending to quit in the next month. In the first population-level study examining reasons for discontinuing NRT, general-population smokers who initiate NRT use when attempting to quit are highly likely to discontinue NRT prematurely. Age and culturally-appropriate medication management interventions may increase NRT compliance and improve cessation outcomes.

Smoking continues to be a major preventable cause of early mortality worldwide, and nicotine replacement therapy has been demonstrated to increase rates of abstinence among smokers attempting to quit. Nicotine transdermal systems (also known as nicotine patches) attach to the skin via an adhesive layer composed of a mixture of different-molecular-weight polyisobutylenes (PIBs) in a specific ratio. This randomized, single-dose, 2-treatment, crossover pharmacokinetic (PK) trial assessed the bioequivalence of nicotine patches including a replacement PIB adhesive (test) compared with the PIB adhesive historically used on marketed patches (reference). The test and reference patches were bioequivalent, as determined by the PK parameters of C max and AUC 0-t . In addition, the parameters T max and t 1/2 did not significantly differ between the 2 patches, supporting the bioequivalence finding from the primary analysis. The tolerability profiles of the patches containing the replacement and previously used PIB adhesives were similar; application-site adverse events did not significantly differ between test and reference patches. Overall, these data establish the bioequivalence of the nicotine patch with the replacement PIB adhesive formulation and the previously utilized PIB adhesive formulation. © 2018 The Authors.

Electronic- or e-cigarettes are nicotine-delivery devices commonly used by smokers to quit or reduce smoking. At present, not much is known about the characteristics of smokers who specifically try e-cigarettes to quit smoking compared to the nicotine replacement therapy (NRT) products approved by the U.S. Food and Drug Administration (FDA). Determining the characteristics of smokers who are likely to choose e-cigarettes as cessation aids would help develop strategies to impart valid information about e-cigarettes to such smokers as facts regarding the safety and utility of e-cigarettes emerge. This study is based on 834 daily smokers [mean age=45.8 (standard deviation=13)] from Hawaii. Demographic, smoking- and cessation-related variables were examined as correlates of ever use of e-cigarette only or any FDA-approved NRT product only or both as cessation aids. Results indicated that younger smokers, non-White smokers, and smokers reporting higher income, lower nicotine dependence, shorter smoking history, and higher lifetime quit attempts were more likely to have tried e-cigarettes but not NRT products for help with smoking cessation. Smokers who are attracted to use e-cigarettes but not FDA-approved NRT products may differ from smokers who are likely to have used NRT products but not e-cigarettes in terms of demographic (e.g., age, ethnicity) and smoking- or cessation-related characteristics (e.g., nicotine dependence, quit attempts). Given the lack of knowledge regarding the health effects of e-cigarettes and their efficacy as cessation aids, future research needs to continue characterizing smokers who are likely to use e-cigarettes for smoking cessation.

The estimated number of cigarette smokers in the world is 1.3 billion, expected to rise to 1.7 billion by 2025, with 10 million smokers living in the U.K. Smoking is the leading, preventable death-cause worldwide, being responsible for almost 650,000 deaths in the E.U. annually. A combination of pharmacological interventions, including nicotine replacement therapy, bupropion and varenicline, and behavioural support is the most effective approach to smoking cessation. However, even the best methods have high relapse rates of approximately 75% within 6 months. Electronic (or "e-") cigarettes use battery power to disperse a solution that usually contains propylene glycol or glycerine, water, flavouring and nicotine. E-cigarettes have become the most popular smoking cessation aid in England, however, information on their effects on cardiovascular function is limited and contradictory. As e-cigarettes are not solely nicotine-based products, existing research exploring the effects of nicotine on the cardio-vasculature provides only limited information, while their extensive uptake urges the need of evidence to inform the general public, smokers and policy-makers. This is a pragmatic, 3-group, randomised, assessor-blinded, single-centre trial exploring the cardiovascular physiological effects of the use of e-cigarettes (nicotine-free and nicotine-inclusive, assessed separately) combined with behavioural support as a smoking cessation method in comparison to the combination of NRT and behavioural support. The primary outcome will be macro-vascular function, determined by a Flow Mediated Dilatation ultrasound assessment, 6 months following participants' "quit date". Participants will be assessed at baseline, 3 days following their self-determined "quit date", at intervention end (3 months) and 6 months following their "quite date". Findings are expected to give an indication of the cardiovascular effects of e-cigarettes both in the short- and in the medium-term period

Full Text Available While the adverse effects of conventional cigarettes on human health have been thoroughly examined, in the last 15 years we have witnessed the birth of electronic cigarettes. There are many types of these devices available on the market. Studies are still underway to determine their negative impact on the human body. Electronic cigarettes comprise of power supply and a vaporising system. The user inhales the aerosol produced by heating up the liquid containing nicotine. In contrast with conventional cigarettes, the tobacco is not combusted, thus the compositions of the aerosol and cigarette smoke are considerably different. Out of 93 chemical substances present in the e-cigarette smoke, the aerosol contains only acetaldehyde, acetone, acrolein, formaldehyde and nicotine. More toxic substances, such as polycyclic aromatic hydrocarbons and heavy metals, are not present. The amount of evidence suggesting electronic cigarettes’ harmful effects on the human body is constantly increasing. Some reports imply that the electronic cigarettes negatively influence pregnancy, human psyche, respiratory and cardiovascular systems. They might also be involved in oncogenesis. With electronic cigarettes constantly gaining popularity, the question about the adverse effects of passive smoking becomes increasingly more relevant. Although various methods of helping people cease smoking or delivering nicotine to their bodies without burning toxic substances are being explored, electronic cigarettes are not recommended in nicotine substitution therapy. Legal regulations regarding electronic cigarettes are still being worked on. The purpose of this paper is to evaluate the effects electronic cigarettes have on the human’s health.

To systematically review the literature regarding relative risk perceptions (RRPs) across non-combustible nicotine products. MEDLINE and PsycINFO databases were searched for articles published up to October 2014. Of the 5266 records identified, articles not published in English that did not quantitatively assess RRPs across categories of non-combustible nicotine products were excluded, yielding 55 records. One reviewer extracted measures and findings of RRPs for product comparisons of smokeless tobacco (SLT), e-cigarettes (ECs) and nicotine replacement therapy (NRT) to one another, and to combustible cigarettes (CCs). A total of 157 samples from 54 studies were included in the analyses. The accuracy of RRPs differed based on the products being compared: although the accuracy of RRPs was variable across studies, substantial proportions of respondents reported inaccurate beliefs about the relative harmfulness of SLT versus CCs, as well as of ECs versus NRT. In addition, in most studies, respondents did not know the relative harmfulness of SLT versus NRT. In contrast, respondents in many studies correctly perceived NRT and ECs as less harmful than CCs. Cigarette smokers and users of non-combustible nicotine products tended to correctly perceive the relative harmfulness of products more often than non-users. Measures used to assess RRPs varied across studies, with different approaches characterised by certain strengths and limitations. The highly variable and context-specific nature of non-combustible nicotine product RRPs have direct implications for researchers and present several challenges for policymakers working with modified risk products, including issues of measurement, health risk communication and behaviour change.

Can Seeking Happiness Make People Happy? Paradoxical Effects of Valuing Happiness

Science.gov (United States)

Mauss, Iris B.; Tamir, Maya; Anderson, Craig L.; Savino, Nicole S.

2011-01-01

Happiness is a key ingredient of well-being. It is thus reasonable to expect that valuing happiness will have beneficial outcomes. We argue that this may not always be the case. Instead, valuing happiness could be self-defeating because the more people value happiness, the more likely they will feel disappointed. This should apply particularly in positive situations, in which people have every reason to be happy. Two studies support this hypothesis. In Study 1, female participants who valued happiness more (vs. less) reported lower happiness when under conditions of low, but not high, life stress. In Study 2, compared to a control group, female participants who were experimentally induced to value happiness reacted less positively to a happy, but not a sad, emotion induction. This effect was mediated by participants’ disappointment at their own feelings. Paradoxically, therefore, valuing happiness may lead people to be less happy just when happiness is within reach.

It has been observed that Nicotine Replacement Therapy (NRT) is one of the alternatives to control and reduce smoking addiction among smokers. Since the decision to choose the best NRT alternative involves uncertainty, ambiguity factors and diverse input datasets, thus, this paper proposes a fuzzy multi-criteria analysis (FMA) to overcome these issues. It focuses on how the fuzzy approach can unify the diversity of datasets based on NRT's decision-making problem. The analysis done employed the advantage of the cost-benefit criterion to unify the mixture of dataset input. The performance matrix was utilised to derive the performance scores. An empirical example regarding the NRT's decision-making problem was employed to illustrate the proposed approach. Based on the calculations, this analytical approach was found to be highly beneficial in terms of usability. It was also very applicable and efficient in dealing with the mixture of input datasets. Hence, the decision-making process can easily be used by experts and patients who are interested to join the therapy/cessation program.

On the basis of the theoretical distinction between self-centeredness and selflessness (Dambrun and Ricard, 2011), the main goal of this research was to develop two new scales assessing distinct dimensions of happiness. By trying to maximize pleasures and to avoid displeasures, we propose that a self-centered functioning induces a fluctuating happiness in which phases of pleasure and displeasure alternate repeatedly (i.e., Fluctuating Happiness). In contrast, a selfless psychological functioning postulates the existence of a state of durable plenitude that is less dependent upon circumstances but rather is related to a person’s inner resources and abilities to deal with whatever comes his way in life (i.e., Authentic–Durable Happiness). Using various samples (n = 735), we developed a 10-item Scale measuring Subjective Fluctuating Happiness (SFHS) and a 13-item scale assessing Subjective Authentic–Durable Happiness (SA–DHS). Results indicated high internal consistencies, satisfactory test–retest validities, and adequate convergent and discriminant validities with various constructs including a biological marker of stress (salivary cortisol). Consistent with our theoretical framework, while self-enhancement values were related only to fluctuating happiness, self-transcendence values were related only to authentic–durable happiness. Support for the distinction between contentment and inner-peace, two related markers of authentic happiness, also was found. PMID:22347202

Our group recently completed a randomized controlled trial, evaluating the efficacy of providing 5 weeks of free nicotine replacement therapy (NRT; in the form of the nicotine patch) by expedited postal mail without behavioral assistance to regular adult smokers interested in receiving it. The findings revealed that mailed provision of nicotine patches resulted in more than a doubling of quit rates at a six-month follow-up compared to a no intervention control group. While this trial provided evidence for the effectiveness of mailed nicotine patches in promoting cessation, the findings speak only to the short term effectiveness of this approach. As relapse to smoking is known to occur beyond the 6 month period, it is important to evaluate whether the net benefit of NRT in naturalistic settings can be maintained long-term. The present study aims to perform a 5-year follow-up survey of participants in the original trial to evaluate the long-term effectiveness of mailed NRT. Trained interviewers will contact participants in the randomized controlled trial 5 years post-enrollment. A total of 924 participants will be eligible to be contacted. Interviewers will first assess participants' smoking status and their level of nicotine dependence. Participants reporting not currently smoking will be asked whether they have smoked tobacco, even a puff, in the last 30 days (primary outcome measure: 30-day point prevalence abstinence), past 6 months (secondary outcome measure: prolonged 6-month abstinence), and since the 8-week follow-up survey (secondary outcome measure: > 4 year continuous abstinence). Interviewers will be blind to experimental condition at the time the primary outcome measure will be assessed. It is hypothesized that participants who received nicotine patches at baseline will display significantly higher quit rates at the 5-year follow-up as compared to participants who did not receive nicotine patches at baseline. If the study finds that the mailed

The impact of advertising on nicotine replacement therapy demand.

While much is known about the economic determinants of tobacco use, very little is known about the economic determinants of nicotine replacement therapy (NRT) use. This paper is the first econometric study to examine the impact of advertising on NRT demand. Pooled cross-sectional time-series scanner-based data for 50 major metropolitan markets in the USA covering the period between the second quarter of 1996 and the second quarter of 2002 are used in the analysis. Fixed-effects modeling is employed to estimate the NRT demand equation. The estimates indicate that increased advertising of Nicoderm CQ transdermal patches and Nicotrol transdermal patches increases per-capita sales of established Nicoderm CQ and Nicotrol products, respectively. However, increased advertising of Nicorette polacrilex (gum) was found not to significantly increase sales of established Nicorette products. Moreover, decreases in the price of NRT and increases in the price of cigarettes were found to increase per-capita sales of NRT products. Given the documented efficacy of NRT, measures to increase peoples' awareness of NRT products through advertising, measures to decrease the price of NRT, and measures to increase the price of cigarettes would be effective means to increase the use of NRT, likely leading to decreased cigarette smoking and reductions in the future public health burden caused by tobacco use.

The current evidence base is limited to three randomized trials (only one compares ECs with nicotine replacement therapy and a growing number of EC user surveys (n=6, case reports (n=4, and cohort studies (n=8. Collectively, these studies suggest modest cessation efficacy and a few adverse effects, at least with the short-term use. On this basis, we provide advice for health care providers on providing balanced information for patients who enquire about ECs. More research, specifically well-conducted large efficacy trials comparing ECs with standard smoking cessation management (eg, nicotine replacement therapy plus behavioral support and long-term prospective studies for adverse events, are urgently needed to fill critical knowledge gaps on these products.

Use of e-cigarettes has been increasing exponentially, with the primary motivation reported as smoking cessation. To understand why smokers choose e-cigarettes as an alternative to cigarettes, as well as to US Food and Drug Administration (FDA)--approved nicotine replacement therapies (NRT), we compared outcome expectancies (beliefs about the results of drug use) for the three nicotine delivery systems among vapers, i.e., e-cigarette users, who were former smokers. Vapers (N = 1,434) completed an online survey assessing 14 expectancy domains as well as perceived cost and convenience. We focused on comparisons between e-cigarettes and cigarettes to determine the attraction of e-cigarettes as a smoking alternative and between e-cigarettes and NRT to determine perceived advantages of e-cigarettes over FDA-approved pharmacotherapy. Participants believed that e-cigarettes, in comparison to conventional cigarettes, had fewer health risks; caused less craving, withdrawal, addiction, and negative physical feelings; tasted better; and were more satisfying. In contrast, conventional cigarettes were perceived as better than e-cigarettes for reducing negative affect, controlling weight, providing stimulation, and reducing stress. E-cigarettes, compared to NRT, were perceived to be less risky, cost less, cause fewer negative physical feelings, taste better, provide more satisfaction, and be better at reducing craving, negative affect, and stress. Moderator analyses indicated history with ad libitum forms of NRT was associated with less positive NRT expectancies. The degree to which expectancies for e-cigarettes differed from expectancies for either tobacco cigarettes or NRT offers insight into the motivation of e-cigarette users and provides guidance for public health and clinical interventions to encourage smoking-related behavior change. © The Author 2014.

Renal transport and metabolism of nicotinic acid

International Nuclear Information System (INIS)

Schuette, S.; Rose, R.C.

1986-01-01

Renal metabolism and brush-border transport of nicotinic acid were studied in renal cortical slices and brush-border membrane vesicles exposed to a physiological concentration of vitamin (2.2-3.5 microM). Vesicle transport of [ 3 H]nicotinic acid was found to be Na+ dependent and concentrative. The presence of a Na+ gradient resulted in a fivefold increase in the rate of nicotinic acid uptake over that observed with mannitol and caused a transient nicotinic acid accumulation two- to fourfold above the equilibrium value. The effects of membrane potential, pH, and elimination of Na+-H+ exchange were also studied. Cortical slices and isolated tubules exposed to 2.2 microM [ 14 C]nicotinic acid took up vitamin and rapidly metabolized most of it to intermediates in the Preiss-Handler pathway for NAD biosynthesis; little free nicotinic acid was detectable intracellularly. The replacement of Na+ with Li+ in the bathing medium reduced total accumulation of 14 C label primarily as a result of reduced nicotinic acid uptake. Cortical tissue concentrated free nicotinic acid only when the involved metabolic pathways were saturated by levels of nicotinic acid far in excess of what occurs in vivo

Although many states have expanded Medicaid coverage of cessation medications, utilization remains low. Anecdotal reports suggest that beneficiaries are at times denied coverage of cessation medications at the pharmacy counter. We conducted an observational community-wide case study of Medicaid beneficiary attempts to fill over-the-counter nicotine replacement therapy at pharmacies. We recruited tobacco-using beneficiaries from a Federally Qualified Health Center, whose providers wrote paper prescriptions for nicotine patches. Study staff escorted beneficiaries to all eligible pharmacies (n = 18) in a Midwestern community to observe fill attempts. Study staff recorded encounters via smartphone into a secure database on a university server. Seven of 18 pharmacies (39%) did not fill the prescription on the day of the attempt. Of these, 6 offered to order the patch for pick-up at a later date. All (4/4) chain pharmacies filled the prescription; 2/3 mass merchant pharmacies failed to fill. Combining successful same-day fills with offers to order for pick-up, 17/18 (94%) would ultimately have been able to obtain patches. This pilot study found that many beneficiaries left pharmacies without a prescription in hand. Successful same-day fills varied markedly by store type. For people with low incomes, transportation presents a major barrier for delayed pick-up. In addition, delays can fuel ambivalence toward quitting. Future research based on this pilot study might address whether patients who fail to secure a same-day prescription ever fill the prescription and, if not, the degree to which this barrier contributes to success or failure in quitting.

Full Text Available The pursuit of happiness is a desire that everyone has in life. The behavioral economics can help to identify constraints to achieve the true happiness. This study made an attempt to identify some possible determinants to explain the happiness of university professors in higher education institutions in the city of Passo Fundo/RS. Data were collected through questionnaires and analyzed using multiple regression models in seven different groups, classified into happiness by sex; happiness by marital status; happiness by age; happiness and money; happiness, sports and health; happiness, friendship, love relationships and sex life; and happiness, creativity and organization. The results show that money is not one of the major constraints to achieve happiness in this analysis group, that love relationships significantly increase the happiness of this study group, once sexual relationships don’t represent happiness increasing. It was also found that emotional / mental health of the participants has significance to turn them happier as creative tasks and planning actions to the future to reach the dreams and goals demonstrate to increase the happiness of this sample of university teachers.

Full Text Available Background. Identification of the predictors of treatment success in smoking cessation may help healthcare workers to improve the effectiveness of attempts at quitting.Objective. To identify the predictors of success in a randomised controlled trial comparing varenicline alone or in combination with nicotine replacement therapy (NRT.Methods. A post-hoc analysis of the data of 435 subjects who participated in a 24-week, multicentre trial in South Africa was performed. Logistic regression was used to analyse the effect of age, sex, age at smoking initiation, daily cigarette consumption, nicotine dependence, and reinforcement assessment on abstinence rates at 12 and 24 weeks. Point prevalence and continuous abstinence rates were self-reported and confirmed biochemically with exhaled carbon monoxide readings.Results. The significant predictors of continuous abstinence at 12 and 24 weeks on multivariate analysis were lower daily cigarette consumption (odds ratio (OR 1.86, 95% confidence interval (CI 1.21 - 2.87, p=0.005 and OR 1.83, 95% CI 1.12 - 2.98, p=0.02, respectively and older age (OR 1.52, 95% CI 1.00 - 2.31, p=0.049 and OR 1.79, 95% CI 1.13 - 2.84, p=0.01, respectively. There was no difference in the predictors of success in the univariate analysis, except that older age predicted point prevalence abstinence at 12 weeks (OR 1.47, 95% CI 1.00 - 2.15, p=0.049. The findings were inconclusive for an association between abstinence and lower nicotine dependence, older age at smoking initiation and positive reinforcement.Conclusion. Older age and lower daily cigarette consumption are associated with a higher likelihood of abstinence in patients using varenicline, regardless of the addition of NRT.

Recently, New York City and New York State increased cigarette excise taxes and New York City implemented a smoke-free workplace law. To assess the impact of these policies on smoking cessation in New York City, we examined over-the-counter sales of nicotine replacement therapy (NRT) products. Pharmacy sales data were collected in real time as part of nontraditional surveillance activities. We used Poisson generalized estimating equations to analyze the effect of smoking-related policies on pharmacy-specific weekly sales of nicotine patches and gum. We assessed effect modification by pharmacy location. We observed increases in NRT product sales during the weeks of the cigarette tax increases and the smoke-free workplace law. Pharmacies in low-income areas generally had larger and more persistent increases in response to tax increases than those in higher-income areas. Real-time monitoring of existing nontraditional surveillance data, such as pharmacy sales of NRT products, can help assess the effects of public policies on cessation attempts. Cigarette tax increases and smoke-free workplace regulations were associated with increased smoking cessation attempts in New York City, particularly in low-income areas.

Full Text Available The use of electronic cigarettes (e-cigs continues to increase worldwide in parallel with accumulating information on their potential toxicity and safety. In this study, an in vitro battery of established assays was used to examine the cytotoxicity, mutagenicity, genotoxicity and inflammatory responses of certain commercial e-cigs and compared to tobacco burning cigarettes, smokeless tobacco (SLT products and a nicotine replacement therapy (NRT product. The toxicity evaluation was performed on e-liquids and pad-collected aerosols of e-cigs, pad-collected smoke condensates of tobacco cigarettes and extracts of SLT and NRT products. In all assays, exposures with e-cig liquids and collected aerosols, at the doses tested, showed no significant activity when compared to tobacco burning cigarettes. Results for the e-cigs, with and without nicotine in two evaluated flavor variants, were very similar in all assays, indicating that the presence of nicotine and flavors, at the levels tested, did not induce any cytotoxic, genotoxic or inflammatory effects. The present findings indicate that neither the e-cig liquids and collected aerosols, nor the extracts of the SLT and NRT products produce any meaningful toxic effects in four widely-applied in vitro test systems, in which the conventional cigarette smoke preparations, at comparable exposures, are markedly cytotoxic and genotoxic.

Nicotine exposure during pregnancy through cigarette smoking, nicotine replacement therapies or e-cigarette use continues to be a widespread public health problem, impacting both fetal and postnatal health. Yet, at this time, there remains limited data regarding the safety and efficacy in using these nicotine products during pregnancy. Notably, reports assessing the effect of nicotine exposure on postnatal health outcomes in humans, including reproductive health, are severely lacking. Our current understanding regarding the consequences of nicotine exposure during pregnancy is limited to a few animal studies, which do not comprehensively address the underlying cellular mechanisms involved. This paper aims to critically review the current knowledge from human and animal studies regarding the direct and indirect effects (e.g. obesity) of maternal nicotine exposure, regardless of its source, on reproductive outcomes in pregnancy and postnatal life. Furthermore, this review highlights several key cellular mechanisms involved in these adverse reproductive deficits including oxidative stress, inflammation, and endoplasmic reticulum (ER) stress. By understanding the interplay of the cellular mechanisms involved, further strategies could be developed to prevent the reproductive abnormalities resulting from exposure to nicotine in utero and influence informed clinical guidelines for pregnant women. © 2015 Society for Reproduction and Fertility.

A non-invasive phenotypic indicator of the rate of nicotine metabolism is nicotine metabolite ratio (NMR) defined as a ratio of two major metabolites of nicotine - trans-3'-hydroxycotinine/cotinine. The rate of nicotine metabolism has important clinical implications for the likelihood of successful quitting with nicotine replacement therapy (NRT). We conducted a study to measure NMR among Polish smokers. In a cross-sectional study of 180 daily cigarette smokers (42% men; average age 34.6±13.0), we collected spot urine samples and measured trans-3'-hydroxycotinine (3-HC) and cotinine levels with LC-MS/MS method. We calculated NMR (molar ratio) and analyzed variations in NMR among groups of smokers. In the whole study group, an average NMR was 4.8 (IQR 3.4-7.3). The group of women below 51 years had significantly greater NMR compared to the rest of the population (6.4; IQR 4.1-8.8 vs. 4.3; IQR 2.8-6.4). No differences were found among group ages of male smokers. This is a first study to describe variations in nicotine metabolism among Polish smokers. Our findings indicate that young women metabolize nicotine faster than the rest of population. This finding is consistent with the known effects of estrogen to induce CYP2A6 activity. Young women may require higher doses of NRT or non-nicotine medications for most effective smoking cessation treatment. Copyright © 2017 Institute of Pharmacology, Polish Academy of Sciences.

2015-06-01

Full Text Available Older adults have been shown to describe their happiness as lower in arousal when compared to younger adults. In addition, older adults prefer low arousal positive emotions over high arousal positive emotions in their daily lives. We experimentally investigated whether or not changing a few words in the description of happiness could influence a person’s rating of their happiness. We randomly assigned 193 participants, aged 22-92 years, to one of three conditions (high arousal, low arousal, or control. In line with previous findings, we found that older participants rated their happiness lower when framed as high in arousal (i.e., ecstatic, to be bursting with positive emotions and rated their happiness higher when framed as low in arousal (i.e., satisfied, to have a life filled with positive emotions. Younger adults remained uninfluenced by the manipulation. Our study demonstrates that arousal is essential to understanding ratings of happiness, and gives support to the notion that there are age differences in the preference for arousal.

Waterpipe tobacco products: nicotine labelling versus nicotine delivery.

Vansickel, Andrea R; Shihadeh, Alan; Eissenberg, Thomas

2012-05-01

Waterpipe tobacco package labelling typically indicates "0.0% tar" and "0.05% or 0.5% nicotine". To determine the extent to which nicotine labeling is related to nicotine delivery. 110 waterpipe smokers engaged in a 45-minute waterpipe smoking session. Puff topography and plasma nicotine were measured. Three waterpipe tobacco brands were used: Nakhla (0.5% nicotine), Starbuzz (0.05% nicotine), and Al Fakher (0.05% nicotine). Data were analyzed by one-way ANOVA. Topography did not differ across brands. Peak plasma nicotine varied significantly across brands. Al Fakher had the highest nicotine delivery (11.4 ng/ml) followed by Nakhla (9.8 ng/ml) and Starbuzz (5.8 ng/ml). Nicotine labelling on waterpipe tobacco products does not reflect delivery; smoking a brand with a "0.05% nicotine" label led to greater plasma nicotine levels than smoking a brand with a "0.5% nicotine" label. Waterpipe tobacco products should be labelled in a manner that does not mislead consumers.

Previous sociological research has focused on macro forces that are associated with overall happiness with one's life, but it has neglected an analysis of happiness in immediate situations and the micro forces that may shape it. In this study, we examine social structural as well as individual factors that may influence happiness in situations that are morally challenging. Data are examined from an experiment in which satisfying self-interests may involve cheating to get ahead. The results reveal that while distal, structural factors influence happiness for those who do not cheat, proximal, individual factors influence happiness for those who cheat. We discuss how both macro and micro forces may shape happiness in situations. Copyright © 2016 Elsevier Inc. All rights reserved.

Extended nicotine self-administration increases sensitivity to nicotine, motivation to seek nicotine and the reinforcing properties of nicotine-paired cues.

Science.gov (United States)

Clemens, Kelly J; Lay, Belinda P P; Holmes, Nathan M

2017-03-01

An array of pharmacological and environmental factors influence the development and maintenance of tobacco addiction. The nature of these influences likely changes across the course of an extended smoking history, during which time drug seeking can become involuntary and uncontrolled. The present study used an animal model to examine the factors that drive nicotine-seeking behavior after either brief (10 days) or extended (40 days) self-administration training. In Experiment 1, extended training increased rats' sensitivity to nicotine, indicated by a leftward shift in the dose-response curve, and their motivation to work for nicotine, indicated by an increase in the break point achieved under a progressive ratio schedule. In Experiment 2, extended training imbued the nicotine-paired cue with the capacity to maintain responding to the same high level as nicotine itself. However, Experiment 3 showed that the mechanisms involved in responding for nicotine or a nicotine-paired cue are dissociable, as treatment with the partial nicotine receptor agonist, varenicline, suppressed responding for nicotine but potentiated responding for the nicotine-paired cue. Hence, across extended nicotine self-administration, pharmacological and environmental influences over nicotine seeking increase such that nicotine seeking is controlled by multiple sources, and therefore highly resistant to change. © 2015 Society for the Study of Addiction.

Two open-label randomized cross-over studies in Japanese smokers investigated the single-use nicotine pharmacokinetic profile of the Tobacco Heating System (THS) 2.2, cigarettes (CC) and nicotine replacement therapy (Gum). In each study, one on the regular and one on the menthol variants of the THS and CC, both using Gum as reference, 62 subjects were randomized to four sequences: Sequence 1: THS - CC (n = 22); Sequence 2: CC - THS (n = 22); Sequence 3: THS - Gum (n = 9); Sequence 4: Gum - THS (n = 9). Plasma nicotine concentrations were measured in 16 blood samples collected over 24 h after single use. Maximal nicotine concentration (C max ) and area under the curve from start of product use to time of last quantifiable concentration (AUC 0-last ) were similar between THS and CC in both studies, with ratios varying from 88 to 104% for C max and from 96 to 98% for AUC 0-last . Urge-to-smoke total scores were comparable between THS and CC. The THS nicotine pharmacokinetic profile was close to CC, with similar levels of urge-to-smoke. This suggests that THS can satisfy smokers and be a viable alternative to cigarettes for adult smokers who want to continue using tobacco. Copyright © 2017 The Authors. Published by Elsevier Inc.

Lee, Peter N; Fariss, Marc W

2017-04-01

We conducted a systematic literature review to identify and critically evaluate studies of serious adverse health effects (SAHEs) in humans using nicotine replacement therapy (NRT) products. Serious adverse health effects refer to adverse events, leading to substantial disruption of the ability to conduct normal life functions. Strength of evidence evaluations and conclusions were also determined for the identified SAHEs. We evaluated 34 epidemiological studies and clinical trials, relating NRT use to cancer, reproduction/development, CVD, stroke and/or other SAHEs in patients, and four meta-analyses on effects in healthy populations. The overall evidence suffers from many limitations, the most significant being the short-term exposure (≤12 weeks) and follow-up to NRT product use in most of the studies, the common failure to account for changes in smoking behaviour following NRT use, and the sparse information on SAHEs by type of NRT product used. The only SAHE from NRT exposure we identified was an increase in respiratory congenital abnormalities reported in one study. Limited evidence indicated a lack of effect between NRT exposure and SAHEs for CVD and various reproduction/developmental endpoints. For cancer, stroke and other SAHEs, the evidence was inadequate to demonstrate any association with NRT use. Our conclusions agree with recent statements from authoritative bodies.

Objectives. We surveyed the availability of tobacco products and nonprescription nicotine replacement therapy (NRT) in pharmacies in New York City, stratified by the race, ethnicity, and socioeconomic status (SES) of the surrounding neighborhoods to determine whether disparities in availability existed. Methods. Surveyors visited a random sample of retail pharmacies to record the availability of tobacco products and nonprescription NRT. We used census data and geographic information systems analysis to determine the SES of each neighborhood. We used logistic modeling to explore relations between SES and the availability of NRT and tobacco products. Results. Of 646 pharmacies sampled, 90.8% sold NRT and 46.9% sold cigarettes. NRT and cigarettes were slightly more available in pharmacies in neighborhoods with a higher SES. NRT was more expensive in poorer neighborhoods. Conclusions. Small disparities existed in access to nonprescription NRT and cigarettes. The model did not adequately account for cigarette access, because of availability from other retail outlets. These results may explain some of the excess prevalence of cigarette use in low-SES areas. PMID:19638596

2015-11-01

Nicotine poisoning is well described in the pediatric population, and even small oral doses may result in toxic effects. The source of nicotine is usually tobacco products and nicotine replacement products such as gum and patches. With the more frequent use of novel products such as e-cigarettes, concern has arisen regarding liquid nicotine. As there are no regulations regarding childproof bottling and packaging, there may be increased potential for unintentional ingestion of these colorfully and appealingly packaged products by children. We present and discuss a case of this nature, as we feel emergency physicians should be aware of this new mode of poisoning, and public health efforts should be made to minimize such exposures.

HAPPINESS AT WORK

Full Text Available One of the main goals of work and organisational psychology is to promote the well-being and performance of employees. However, the different authors do not agree on the fundamental concept of happiness. The objectives of this paper are to present the enormous contribution of positive psychology and philosophy to the subject of happiness and its influence on labour and productivity, to review several scholars in this field, to highlight the differences among them, and, especially, to find a consensus on the fundamentals of happiness. In fact, the major difference among all the contributions is that there is no unanimity on the fundamental concept of happiness. Whereas some authors see happiness as “pleasure”, others prefer the concept of happiness as a mixture of “pleasure”, “engagement” and “meaning”, avoiding the definition of happiness, and hiding it behind the concept of well-being. However, if a consensus were reached, it would represent a concept that could be better managed from the psychological perspective

Happiness Function in an Islamic Economy: Triple Economic Growth, Fair Distribution and Human Happiness

Full Text Available This study investigated the characteristics of happiness function in an Islamic economy framework. It analyzed the nature and trend of the link between economic growth, equal distribution and level of human happiness. These interrelated concepts form the essence of this study problem. The study assumed four main possible tracks for the happiness function in an Islamic economy, which ultimately emphasized the wider concept of happiness that includes faith and moral values. It indicates that people’s happiness increases with the increase of material and non material resources. However, happiness increases even if material resources decline. That is a case which reflects impact of faith and moral values on people’s happiness. The study indicated the importance of conducting empirical and field studies to examine the effect of material and non- material potentials on happiness. Keywords: Happiness function, Material resources for Happiness, Nonmaterial resources for happiness, Economic growth, Equal distribution.

Validation of a LC-MS/MS method for quantifying urinary nicotine, six nicotine metabolites and the minor tobacco alkaloids--anatabine and anabasine--in smokers' urine.

Directory of Open Access Journals (Sweden)

James E McGuffey

Full Text Available Tobacco use is a major contributor to premature morbidity and mortality. The measurement of nicotine and its metabolites in urine is a valuable tool for evaluating nicotine exposure and for nicotine metabolic profiling--i.e., metabolite ratios. In addition, the minor tobacco alkaloids--anabasine and anatabine--can be useful for monitoring compliance in smoking cessation programs that use nicotine replacement therapy. Because of an increasing demand for the measurement of urinary nicotine metabolites, we developed a rapid, low-cost method that uses isotope dilution liquid chromatography-tandem mass spectrometry (LC-MS/MS for simultaneously quantifying nicotine, six nicotine metabolites, and two minor tobacco alkaloids in smokers' urine. This method enzymatically hydrolyzes conjugated nicotine (primarily glucuronides and its metabolites. We then use acetone pretreatment to precipitate matrix components (endogenous proteins, salts, phospholipids, and exogenous enzyme that may interfere with LC-MS/MS analysis. Subsequently, analytes (nicotine, cotinine, hydroxycotinine, norcotinine, nornicotine, cotinine N-oxide, nicotine 1'-N-oxide, anatabine, and anabasine are chromatographically resolved within a cycle time of 13.5 minutes. The optimized assay produces linear responses across the analyte concentrations typically found in urine collected from daily smokers. Because matrix ion suppression may influence accuracy, we include a discussion of conventions employed in this procedure to minimize matrix interferences. Simplicity, low cost, low maintenance combined with high mean metabolite recovery (76-99%, specificity, accuracy (0-10% bias and reproducibility (2-9% C.V. make this method ideal for large high through-put studies.

Integral Perspective on Happiness

Joonas Uotinen

2015-05-01

Full Text Available A happiness science has emerged amidst, and spans, the social sciences. This research, despite the long philosophical tradition on happiness, is in its infancy and a robust theory of happiness is called for. I will review parts of the literature and some of the main happiness theories using Ken Wilber’s Integral approach. I will concentrate largely on Aristotle’s eudaimonia, as that has re-emerged into the centre of happiness discussions as a possible contender for the prevailing subjective happiness theories. The Integral approach seems to provide valuable insights into many happiness theories, juxtapose them in a comprehensible way, pinpoint deficiencies, and propose enhancements. Amongst other things, I will propose a new happiness theory combining John Kekes’ happiness theory with ecological ethics and I will conclude that enlightenment proves to be a good candidate for the ultimate good, or summum bonum, I will enlarge on Aristotle’s theory and propose that Wilber’s theory provides an ‘Integral road map towards eudaimonia enhanced – the enlightenment’. I will argue that eudaimonia and enlightenment, though superficially dissimilar, accord in surprising ways, to a great extent. I will discuss whether the discussion of happiness and morality is critically biased, and I will discuss the societal implications that Wilber’s conception of the human might have through its implications for happiness theories.

Nicotine inhibits potassium currents in Aplysia bag cell neurons

Science.gov (United States)

White, Sean H.; Sturgeon, Raymond M.

2016-01-01

Acetylcholine and the archetypal cholinergic agonist, nicotine, are typically associated with the opening of ionotropic receptors. In the bag cell neurons, which govern the reproductive behavior of the marine snail, Aplysia californica, there are two cholinergic responses: a relatively large acetylcholine-induced current and a relatively small nicotine-induced current. Both currents are readily apparent at resting membrane potential and result from the opening of distinct ionotropic receptors. We now report a separate current response elicited by applying nicotine to cultured bag cell neurons under whole cell voltage-clamp. This current was ostensibly inward, best resolved at depolarized voltages, presented a noncooperative dose-response with a half-maximal concentration near 1.5 mM, and associated with a decrease in membrane conductance. The unique nicotine-evoked response was not altered by intracellular perfusion with the G protein blocker GDPβS or exposure to classical nicotinic antagonists but was occluded by replacing intracellular K+ with Cs+. Consistent with an underlying mechanism of direct inhibition of one or more K+ channels, nicotine was found to rapidly reduce the fast-inactivating A-type K+ current as well as both components of the delayed-rectifier K+ current. Finally, nicotine increased bag cell neuron excitability, which manifested as reduction in spike threshold, greater action potential height and width, and markedly more spiking to continuous depolarizing current injection. In contrast to conventional transient activation of nicotinic ionotropic receptors, block of K+ channels could represent a nonstandard means for nicotine to profoundly alter the electrical properties of neurons over prolonged periods of time.

Nicotine replacement therapy (NRT) increases the probability of smoking cessation. This study was conducted to determine if three prototype 4-mg nicotine lozenges produced locally in India were bioequivalent to a globally marketed reference product, Nicorette® 4-mg nicotine lozenge. Healthy adult smokers (N = 39) were treated with three prototype 4-mg nicotine lozenges in comparison with a reference 4-mg lozenge in this single-center, randomized, open-label, single-dose, 4-way crossover study. Pharmacokinetic sampling was obtained to test for bioequivalence using maximal plasma concentration (Cmax) and extent of absorption (AUC0-t). Secondarily, AUC;0-∞, time to maximal plasma concentration (tmax), half-life (T1/2), elimination rate constant (Kel), and safety of the prototype lozenges versus the reference lozenge were compared. Each prototype 4-mg nicotine lozenge was found to be bioequivalent to the reference 4-mg nicotine lozenge based on the ratio of geometric means and 90% confidence intervals for Cmax, AUC0-t, and AUC;0-∞. Although tmax; was significantly longer for prototype III, all four lozenges achieved maximum plasma nicotine concentrations at a median of 1.5 hours. The safety profiles of the three prototype 4-mg lozenges did not differ from that of the 4-mg reference product. Each prototype 4-mg nicotine lozenge was bioequivalent to the reference 4-mg nicotine lozenge and was well tolerated. Furthermore, as these bioequivalent prototypes differed in in-vitro dissolution profiles, these data suggest that performance from the in -vitro method deployed is not a firm predictor of pharmacokinetic behavior.

DESPERATELY SEEKING HAPPINESS: VALUING HAPPINESS IS ASSOCIATED WITH SYMPTOMS AND DIAGNOSIS OF DEPRESSION.

Science.gov (United States)

Ford, Brett Q; Shallcross, Amanda J; Mauss, Iris B; Floerke, Victoria A; Gruber, June

Culture shapes the emotions people feel and want to feel. In Western cultures, happiness is an emotion that many people want to feel. Although experiencing happiness is associated with increased well-being and psychological health, recent evidence suggests wanting to feel happy to an extreme degree, or, highly valuing happiness, leads to decreased well-being. To examine whether these effects of valuing happiness might extend to clinical outcomes, we examined the hypothesis that depression is associated with highly valuing happiness. To do so, we examined the relationship between valuing happiness and depression in two U.S. samples. As hypothesized, valuing happiness was associated with increased depressive symptoms in a community sample with remitted major depressive disorder (MDD), even when controlling for social desirability and neuroticism (Study 1). Furthermore, valuing happiness was elevated in a remitted MDD sample (vs. healthy controls), even when controlling for current depressive symptoms, general affect valuation, and extreme goal pursuit (Study 2). Taken together, these findings suggest that the culturally-pervasive value placed on attaining happiness can represent a risk factor for symptoms and a diagnosis of depression. More broadly, they indicate that a cultural approach can meaningfully extend our understanding of clinical phenomena.

Answer questions and earn CME/CNE Over the last decade, the use of electronic nicotine delivery systems (ENDS), including the electronic cigarette or e-cigarette, has grown rapidly. More youth now use ENDS than any tobacco product. This extensive research review shows that there are scientifically sound, sometimes competing arguments about ENDS that are not immediately and/or completely resolvable. However, the preponderance of the scientific evidence to date suggests that current-generation ENDS products are demonstrably less harmful than combustible tobacco products such as conventional cigarettes in several key ways, including by generating far lower levels of carcinogens and other toxic compounds than combustible products or those that contain tobacco. To place ENDS in context, the authors begin by reviewing the trends in use of major nicotine-containing products. Because nicotine is the common core-and highly addictive-constituent across all tobacco products, its toxicology is examined. With its long history as the only nicotine product widely accepted as being relatively safe, nicotine-replacement therapy (NRT) is also examined. A section is also included that examines snus, the most debated potential harm-reduction product before ENDS. Between discussions of NRT and snus, ENDS are extensively examined: what they are, knowledge about their level of "harm," their relationship to smoking cessation, the so-called gateway effect, and dual use/poly-use.

2012-01-01

Nicotine replacement therapy (NRT) can help smokers to quit smoking. Nicotine chewing gum has attracted the attention from pharmaceutical industries to offer it to consumers as an easily accessible NRT product. However, the bitter taste of such gums may compromise their acceptability by patients. This study was, therefore, designed to develop 2 and 4 mg nicotine chewing gums of pleasant taste, which satisfy the consumers the most. Nicotine, sugar, liquid glucose, glycerin, different sweetening and taste-masking agents, and a flavoring agent were added to the gum bases at appropriate temperature. The medicated gums were cut into pieces of suitable size and coated by acacia aqueous solution (2% w/v), sugar dusting, followed by acacia-sugar-calcium carbonate until a smooth surface was produced. The gums' weight variation and content uniformity were determined. The release of nicotine was studied in pH 6.8 phosphate buffer using a mastication device which simulated the mastication of chewing gum in human. The Latin Square design was used for the evaluation of organoleptic characteristics of the formulations at different stages of development. Most formulations released 79-83% of their nicotine content within 20 min. Nicotine-containing sugar-coated gums in which aspartame as sweetener and cherry and eucalyptus as flavoring agents were incorporated (i.e. formulations F(19-SC) and F(20-SC), respectively) had optimal chewing hardness, adhering to teeth, and plumpness characteristics, as well as the most pleasant taste and highest acceptability to smokers. Taste enhancement of nicotine gums was achieved where formulations comprised aspartame as the sweetener and cherry and eucalyptus as the flavoring agents. Nicotine gums of pleasant taste may, therefore, be used as NRT to assist smokers quit smoking.

Because electronic cigarettes (e-cigs) containing nicotine may relieve smoking abstinence symptoms similar to nicotine replacement therapy medication, we used within-subjects designs to test these effects with a first-generation e-cig in nonquitting and quitting smokers. In Study 1, 28 nontreatment-seeking smokers abstained overnight prior to each of 3 sessions. Minnesota Nicotine Withdrawal Scale (MNWS) withdrawal (and craving item) relief was assessed following 4 exposures (each 10 puffs) over 2 hr to e-cigs that either did (36 mg/ml) or did not (i.e., placebo, 0 mg/ml) contain nicotine or after no e-cig. Relief was greater after nicotine versus placebo e-cig (p < .05) but not after placebo versus no e-cig, showing relief was due to nicotine per se and not simple e-cig use behavior. Using a crossover design in Study 2, smokers preparing to quit soon engaged in 2 experimental 4-day quit periods on separate weeks. In weeks 1 and 3, all received a nicotine or placebo e-cig on Monday to use ad libitum while trying to abstain from smoking on Tuesday through Friday. (Week 2 involved resumption of ad libitum smoking.) MNWS and Questionnaire of Smoking Urges (QSU) craving were assessed at daily visits following 24-hr abstinence. Of 17 enrolled, 12 quit for ≥24 hr at least once, allowing test of relief because of e-cig use on quit days. Withdrawal and craving were reduced because of nicotine versus placebo e-cig use (both p < .05). In sum, compared with placebo e-cigs, nicotine e-cigs can relieve smoking abstinence symptoms, perhaps in a manner similar to Food and Drug Administration-approved nicotine replacement therapy products, although much more research with larger samples is needed.

Culture shapes the emotions people feel and want to feel. In Western cultures, happiness is an emotion that many people want to feel. Although experiencing happiness is associated with increased well-being and psychological health, recent evidence suggests wanting to feel happy to an extreme degree, or, highly valuing happiness, leads to decreased well-being. To examine whether these effects of valuing happiness might extend to clinical outcomes, we examined the hypothesis that depression is ...

Nicotine addiction is an issue faced by millions of individuals worldwide. As a result, nicotine replacement therapies, such as transdermal nicotine patches, have become widely distributed and used. While the pharmacokinetics of transdermal nicotine have been extensively described using noncompartmental methods, there are few data available describing the between-subject variability in transdermal nicotine pharmacokinetics. The aim of this investigation was to use population pharmacokinetic techniques to describe this variability, particularly as it pertains to the absorption of nicotine from the transdermal patch. A population pharmacokinetic parent-metabolite model was developed using plasma concentrations from 25 participants treated with transdermal nicotine. Covariates tested in this model included: body weight, body mass index, body surface area (calculated using the Mosteller equation) and sex. Nicotine pharmacokinetics were best described with a one-compartment model with absorption based on a Weibull distribution and first-order elimination and a single compartment for the major metabolite, cotinine. Body weight was a significant covariate on apparent volume of distribution of nicotine (exponential scaling factor 1.42). After the inclusion of body weight in the model, no other covariates were significant. This is the first population pharmacokinetic model to describe the absorption and disposition of transdermal nicotine and its metabolism to cotinine and the pharmacokinetic variability between individuals who were administered the patch. © 2017 The British Pharmacological Society.

The use of cigarettes delivering different nicotine doses allows evaluation of the contribution of nicotine to the smoking experience. We compared responses of 46 young adult smokers to research cigarettes, delivering 0.027, 0.110, 0.231, or 0.763 mg nicotine, and conventional cigarettes. On five separate days, craving, withdrawal, affect, and sustained attention were measured after overnight abstinence and again after smoking. Participants also rated each cigarette, and the nicotine metabolite ratio (NMR) was used to identify participants as normal or slow metabolizers. All cigarettes equally alleviated craving, withdrawal, and negative affect in the whole sample, but normal metabolizers reported greater reductions of craving and withdrawal than slow metabolizers, with dose-dependent effects. Only conventional cigarettes and, to a lesser degree, 0.763-mg nicotine research cigarettes increased sustained attention. Finally, there were no differences between ratings of lower-dose cigarettes, but the 0.763-mg cigarettes and (even more so) conventional cigarettes were rated more favorably than lower-dose cigarettes. The findings indicate that smoking-induced relief of craving and withdrawal reflects primarily non-nicotine effects in slow metabolizers, but depends on nicotine dose in normal metabolizers. By contrast, relief of withdrawal-related attentional deficits and cigarette ratings depend on nicotine dose regardless of metabolizer status. These findings have bearing on the use of reduced-nicotine cigarettes to facilitate smoking cessation and on policy regarding regulation of nicotine content in cigarettes. They suggest that normal and slow nicotine metabolizers would respond differently to nicotine reduction in cigarettes, but that irrespective of metabolizer status, reductions to <0.763 mg/cigarette may contribute to temporary attentional deficits.

Full Text Available Happiness is rising on the political agenda and this calls for measures of how well nations perform in creating great happiness for a great number, analogous to measures of success in creating wealth, such as GDP. Happiness is defined as subjective enjoyment of one’s life as-a-whole and this can be measured using self-reports. Question on happiness are currently used in large scale surveys of the general population in nations. As a result we have now comparable data on happiness in 144 contemporary nations and time-series of 25 years and longer on 11 developed nations. These data can be aggregated in different ways: If the aim is simply greater happiness for a greater number of citizens, Average happiness (AH is an appropriate measure. If the focus is on enduring happiness, it is better to combine average happiness with longevity in an index of Happy Life Years (HLY. If the aim is to reduce disparity among citizens a relevant indicator is the Inequality of Happiness (IH in the nations as measured with the standard deviation. Average and dispersion can also be combined in an index of Inequality-Adjusted Happiness (IAH. Comparison across nations shows sizable differences on all these measures of gross national happiness and these differences correspond with societal characteristics that can be influenced by policy makers, such as freedom and justice. Comparison over time shows major improvement during the last decade.

Datu, Jesus Alfonso D; King, Ronnel B; Valdez, Jana Patricia M

2017-04-01

Interdependent happiness has been found to be positively associated with optimal psychological outcomes in collectivist cultures. However, the association between interdependent happiness and key academic outcomes has remained unexplored. The current study examined the association of interdependent happiness with key academic outcomes such as autonomous motivation, engagement, and achievement using both cross-sectional (Study 1) and longitudinal (Study 2) approaches. Study 1 revealed that interdependent happiness positively predicted academic engagement (partly) via autonomous motivation. Study 2 showed that prior interdependent happiness positively predicted subsequent academic engagement even after controlling for autoregressor effects. In addition, reciprocal associations among the key variables were found. Taken together, results of the two studies suggest that interdependent happiness plays an adaptive role in the academic context especially in a collectivist cultural setting. Theoretical and practical implications are discussed. Copyright © 2016 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

True happiness: The role of morality in the folk concept of happiness.

Science.gov (United States)

Phillips, Jonathan; De Freitas, Julian; Mott, Christian; Gruber, June; Knobe, Joshua

2017-02-01

Recent scientific research has settled on a purely descriptive definition of happiness that is focused solely on agents' psychological states (high positive affect, low negative affect, high life satisfaction). In contrast to this understanding, recent research has suggested that the ordinary concept of happiness is also sensitive to the moral value of agents' lives. Five studies systematically investigate and explain the impact of morality on ordinary assessments of happiness. Study 1 demonstrates that moral judgments influence assessments of happiness not only for untrained participants, but also for academic researchers and even in those who study happiness specifically. Studies 2 and 3 then respectively ask whether this effect may be explained by general motivational biases or beliefs in a just world. In both cases, we find evidence against these explanations. Study 4 shows that the impact of moral judgments cannot be explained by changes in the perception of descriptive psychological states. Finally, Study 5 compares the impact of moral and nonmoral value, and provides evidence that unlike nonmoral value, moral value is part of the criteria that govern the ordinary concept of happiness. Taken together, these studies provide a specific explanation of how and why the ordinary concept of happiness deviates from the definition used by researchers studying happiness.

2015-07-01

This article tests a hypothesized model of overall happiness among homeless people in Spain. The research was conducted based on a representative sample of homeless people in Madrid (n = 235), all adults, who had spent the night before the interview in a shelter for homeless people, on the street or in other places not initially designed for sleeping, or who were in supervised accommodation for homeless people at the time of the interview. Information was gathered using a structured interview. The results obtained show that around half of the homeless people in Madrid said that they were happy. A positive meta-stereotype and a better perceived general health were associated with a higher overall happiness, while feelings of loneliness were associated with a lower overall happiness. Happiness also showed a significant effect on future expectations. Disabilities and handicaps had a significant effect on perceived general health, which was in turn associated with overall happiness among homeless people. (c) 2015 APA, all rights reserved).

Weaver, Scott R; Kemp, Catherine B; Heath, J Wesley; Pechacek, Terry F; Eriksen, Michael P

Nicotine in electronic nicotine and non-nicotine delivery systems (ENDS/ENNDS) may present a risk of harm to those with cardiovascular disease and the fetuses of pregnant women. We assessed the extent to which adult users of ENDS/ENNDS used these products with nicotine. We obtained data for this study from a national probability survey of 6051 US adults that was conducted in August and September 2015. Of 399 adult ENDS/ENNDS users who were current smokers, 337 (80.7%) used ENDS/ENNDS containing nicotine, whereas only 29 of 71 (36.9%) ENDS/ENNDS users who were never smokers used ENDS/ENNDS containing nicotine. Assessments of the population health impact of ENDS/ENNDS use among never smokers should take into account the extent to which use involves nicotine.

The present study examined the relationships between four personality traits, humor styles, and happiness. Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life. PMID:27547251

The Activity and Enthalpy of Vaporization of Nicotine from Tobacco at Moderate Temperatures

Directory of Open Access Journals (Sweden)

St.Charles F. Kelley

2016-01-01

Full Text Available The vapor pressure of nicotine has been reported for unprotonated nicotine and for nicotine-water solutions. Yet no published values exist for nicotine in any commercially relevant matrix or for protonated forms (e.g., tobacco, smoke, electronic cigarette solutions, nicotine replacement products, nicotine salts. Therefore a methodology was developed to measure nicotine activity (defined as the vapor pressure from a matrix divided by the vapor pressure of pure nicotine. The headspace concentration of nicotine was measured for pure nicotine and tobacco stored at 23, 30, and 40 °C which allowed for conversion to vapor pressure and nicotine activity and for the estimation of enthalpy of vaporization. Burley, Flue-cured, Oriental, and cigarette blends were tested. Experiments were conducted with pure nicotine initially until the storage and sampling techniques were validated by comparison with previously published values. We found that the nicotine activity from tobacco was less than 1% with Burley > Flue-cured > Oriental. At 23 °C the nicotine vapor pressure averaged by tobacco type was 0.45 mPa for Oriental tobacco, 1.8 mPa for Flue-cured, 13 mPa for Burley while pure nicotine was 2.95 Pa. In general, the nicotine activity increased as the (calculated unprotonated nicotine concentration increased. The nicotine enthalpy of vaporization from tobacco ranged from 77 kJ/mol to 92 kJ/mol with no obvious trends with regard to tobacco origin, type, stalk position or even the wide range of nicotine activity. The mean value for all tobacco types was 86.7 kJ/mol with a relative standard deviation of 6.5% indicating that this was an intrinsic property of the nicotine form in tobacco rather than the specific tobacco properties. This value was about 30 kJ/mol greater than that of pure nicotine and is similar to the energy needed to remove a proton from monoprotonated nicotine.

Effects of Nicotine Metabolites on Nicotine Withdrawal Behaviors in Mice.

Elhassan, Sagi; Bagdas, Deniz; Damaj, M Imad

Rodent studies suggest that nicotine metabolites and minor tobacco alkaloids such as nornicotine and cotinine may promote cigarette smoking by enhancing nicotine rewarding and reinforcing effects. However, there is little information on the effects of these minor tobacco alkaloids on nicotine withdrawal. The present studies were conducted to determine whether the minor tobacco alkaloids nornicotine and cotinine exhibit nicotine-like behavioral effects in a mouse model of spontaneous nicotine withdrawal. Mice were infused with nicotine or saline for 14 days. Experiments were conducted on day 15, 18-24 hours after minipump removal. Ten minutes prior to testing, nicotine-dependent ICR male mice received an acute injection of nicotine (0.05 and 0.5 mg/kg), nornicotine (2.5 and 25 mg/kg), or cotinine (5 and 50 mg/kg) to determine effects on somatic signs, anxiety-like behaviors, and hyperalgesia spontaneous signs of withdrawal. Nicotine and the minor tobacco alkaloid nornicotine, but not cotinine, produced dose-dependent reversal of nicotine withdrawal signs in the mouse. The minor tobacco alkaloid and nicotine metabolite nornicotine at high doses have nicotinic like effects that may contribute to tobacco consumption and dependence. © The Author 2017.

How can so many claim to be happy when so many, we are told, are depressed, anxious or suffering emotional pain? There is no underlying contradiction here, for two reasons: Happiness and depression are manifestations of the same political discourse (or aspects of a political subjectivity characterized by dis-inhibition, consumer self-indulgence and performance anxiety.

2012-10-01

The optimal approach to encourage smoking cessation after acute coronary syndrome (ACS) remains unclear. The safety of nicotine replacement therapy (NRT) after ACS is not well established. The aim of the present study was to determine the relationship between NRT use and adverse cardiovascular outcomes after ACS. Using a pre-existing database, 663 smokers with ACS were identified. The patients were separated into the NRT (n = 184) or control (n = 479) groups according to whether NRT was prescribed on hospital discharge. Multivariate logistic regression analysis was used to account for the baseline differences between the 2 groups. Of the 663 patients, 202 had adverse events in the first year after ACS. No significant differences were seen with NRT use for the 1-year combined end point of death, myocardial infarction), repeat revascularization, or rehospitalization for angina, congestive heart failure or arrhythmia (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.61 to 1.30, p = 0.54). There were no differences in the individual 1-year end points of death (odds ratio 0.80, 95% confidence interval 0.33 to 1.91, p = 0.61), myocardial infarction (odds ratio 0.90, 95% confidence interval 0.40 to 2.06, p = 0.80), repeat revascularization (odds ratio 0.77, 95% confidence interval 0.44 to 1.36, p = 0.37), or rehospitalization for angina, congestive heart failure, or arrhythmia (odds ratio 1.01, 95% confidence interval 0.66 to 1.53, p = 0.97).

Full Text Available Assessing national levels of happiness has become an important research and policy issue in recent years. We examined happiness and satisfaction in Ireland using phone text messaging to collect large-scale longitudinal data from 3,093 members of the general Irish population. For six consecutive weeks participants’ happiness and satisfaction levels were assessed. For four consecutive weeks (weeks 2 to 5 a different random third of the sample got feedback on the previous week's mean happiness and satisfaction ratings. Text messaging proved a feasible means of assessing happiness and satisfaction, with almost three quarters (73% of participants completing all assessments. Those who received feedback on the previous week’s mean ratings were eight times more likely to complete the subsequent assessments than those not receiving feedback. Providing such feedback data on mean levels of happiness and satisfaction did not systematically bias subsequent ratings either towards or away from these normative anchors. Texting is a simple and effective means to collect population level happiness and satisfaction data.

Full Text Available Abstract Background It has been suggested that cigarette smokers will switch to alternative oral nicotine delivery products to reduce their health risks if informed of the relative risk difference. However, it is important to assess how smokers are likely to use cigarette alternatives before making predictions about their potential to promote individual or population harm reduction. Objectives This study examines smokers' interest in using a smokeless tobacco or a nicotine replacement product as a substitute for their cigarettes. Methods The study included 67 adult cigarette smokers, not currently interested in quitting, who were given an opportunity to sample four alternative oral nicotine products: 1 Camel Snus, 2 Marlboro Snus, 3 Stonewall dissolvable tobacco tablets, and 4 Commit nicotine lozenges. At visit 1, subjects were presented information about the relative benefits/risks of oral nicotine delivery compared to cigarettes. At visit 2, subjects were given a supply of each of the four products to sample at home for a week. At visit 3, subjects received a one-week supply of their preferred product to see if using such products reduced or eliminated cigarette use. Results After multiple product sampling, participants preferred the Commit lozenges over the three smokeless tobacco products (p = 0.011. Following the one week single-product trial experience, GEE models controlling for gender, age, level of education, baseline cigarettes use, and alternative product chosen, indicated a significant decline in cigarettes smoked per day across one week of single-product sampling (p Conclusions Findings from this study show that smokers, who are currently unwilling to make a quit attempt, may be willing to use alternative products in the short term as a temporary substitute for smoking. However, this use is more likely to be for partial substitution (i.e. they will continue to smoke, albeit at a lower rate rather than complete substitution. Of the

We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

Happiness: origins, forms, and technical relevance.

Akhtar, Salman

2010-09-01

By critically reviewing Freud's views on happiness, and also those of Helene Deutsch, Bertram Lewin, Melanie Klein, and Heinz Kohut, the author evolves a complex and multilayered perspective on the phenomenon. He categorizes happiness into four related and occasionally overlapping varieties: pleasure-based happiness (elation), assertion-based happiness (joy), merger-based happiness (ecstasy), and fulfillment-based happiness (contentment). After entering some caveats and drawing from his clinical experience, the author then demonstrates the relevance of these ideas to the conduct of psychotherapy and psychoanalysis.

Tobacco addiction is a relapsing disorder that constitutes a substantial worldwide health problem, with evidence suggesting that nicotine and nicotine-associated stimuli play divergent roles in maintaining smoking behavior in men and women. While animal models of tobacco addiction that utilize nicotine self-administration have become more widely established, systematic examination of the multiple factors that instigate relapse to nicotine-seeking have been limited. Here, we examined nicotine self-administration and subsequent nicotine-seeking in male and female Sprague-Dawley rats using an animal model of self-administration and relapse. Rats lever pressed for nicotine (0.03 and 0.05 mg/kg/infusion, IV) during 15 daily 2-h sessions, followed by extinction of lever responding. Once responding was extinguished, we examined the ability of previously nicotine-paired cues (tone+light), the anxiogenic drug yohimbine (2.5mg/kg, IP), a priming injection of nicotine (0.3mg/kg, SC), or combinations of drug+cues to reinstate nicotine-seeking. Both males and females readily acquired nicotine self-administration and displayed comparable levels of responding and intake at both nicotine doses. Following extinction, exposure to the previously nicotine-paired cues or yohimbine, but not the nicotine-prime alone, reinstated nicotine-seeking in males and females. Moreover, when combined with nicotine-paired cues, both yohimbine and nicotine enhanced reinstatement. No significant sex differences or estrous cycle dependent changes were noted across reinstatement tests. These results demonstrate the ability to reinstate nicotine-seeking with multiple modalities and that exposure to nicotine-associated cues during periods of a stressful state or nicotine can increase nicotine-seeking.

Full Text Available Introduction: The role of dental professionals in the society is vital. This profession allows the flexibility to balance a professional and personal life. Practice of dentistry at times is quite stressful, and stress impedes happiness and subjective well-being. Several studies have reported about stress among dental professionals and their various effects; however, studies evaluating the level of happiness (happiness index among dentists are few and lack in this geographic region. Objectives: The present study was conducted to assess the subjective happiness level among dental professionals. Materials and Methods: A cross-sectional study was conducted among 194 dentists in Andhra Pradesh, India. A questionnaire measuring dimensions of professional satisfaction by Subjective Happiness Scale was used to assess the happiness level. The results were expressed in percentages, means, and mean rank. Independent samples nonparametric tests (Mann–Whitney U-test and Kruskal–Wallis test and multivariable analyses were used to assess the determinants of happiness. Results: The mean happiness index of the respondents was 21.71 (0.26 standard error. Overall 67% of the respondents had an above average happiness score. Higher happiness score was found to be significantly associated with age, postgraduate degree, male gender, type of professional attachment, duration of practice, urban location of practice, and spouse employment status in univariate analysis. However, multivariable analysis showed association with type of professional attachment only. Conclusion: Although dentistry has been recognized as a stressful profession, majority of the dentists under study had a happiness score above the mean, and the level of satisfaction was influenced by various sociodemographic factors.

Evaluation of nicotine in tobacco-free-nicotine commercial products.

Recently, a variety of new tobacco-free-nicotine, TFN, products have been commercialized as e-liquids. Tobacco-derived nicotine contains predominantly (S)-(-)-nicotine, whereas TFN products may not. The TFN products are said to be cleaner, purer substances, devoid of toxic components that come from the tobacco extraction process. A variety of commercial tobacco and TFN products were analyzed to identify the presence and composition of each nicotine enantiomer. A rapid and effective enantiomeric separation of nicotine has been developed using a modified macrocyclic glycopeptide bonded to superficially porous particles. The enantiomeric assay can be completed in nicotine, which is present in much greater quantities in commercial TFN products compared to commercial tobacco-derived products. Such studies are required by the FDA for new enantiomeric pharmacological products. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Full Text Available Background. The affective profiles model categorizes individuals as self-fulfilling (high positive affect, low negative affect, high affective (high positive affect, high negative affect, low affective (low positive affect, low negative affect, and self-destructive (low positive affect, high negative affect. The model has been used extensively among Swedes to discern differences between profiles regarding happiness, depression, and also life satisfaction. The aim of the present study was to investigate such differences in a sample of residents of the USA. The study also investigated differences between profiles with regard to happiness-increasing strategies.Methods. In Study I, 900 participants reported affect (Positive Affect Negative Affect Schedule; PANAS and happiness (Happiness-Depression Scale. In Study II, 500 participants self-reported affect (PANAS, life satisfaction (Satisfaction With Life Scale, and how often they used specific strategies to increase their own happiness (Happiness-Increasing Strategies Scales.Results. The results showed that, compared to the other profiles, self-fulfilling individuals were less depressed, happier, and more satisfied with their lives. Nevertheless, self-destructive individuals were more depressed, unhappier, and less satisfied than all other profiles. The self-fulfilling individuals tended to use strategies related to agentic (e.g., instrumental goal-pursuit, communal (e.g., social affiliation, and spiritual (e.g., religion values when pursuing happiness.Conclusion. These differences suggest that promoting positive emotions can positively influence a depressive-to-happy state as well as increasing life satisfaction. Moreover, the present study shows that pursuing happiness through strategies guided by agency, communion, and spirituality is related to a self-fulfilling experience described as high positive affect and low negative affect.

Happiness is a drive and constructive force of life. A person feels wellbeing under different effective factors. Religious dogmatism that has an influence on the entire world is one of the depreciatory factors of happiness or wellbeing. The current study decided to analyze the relation between dogmatism and wellbeing, and according to a model, answer the following question: how does religious dogmatism decrease wellbeing? This study is a correlation research. Population of study includes all people with 30-50 yr old who live in Tehran, Iran, in 2015. Among all, 180 subjects were selected as in access sample. The Oxford happiness questionnaire and Rokeach dogmatism scale were used. Data were analyzed by Pearson correlation test. There is a significant negative correlation between dogmatism and happiness (α=0.05). Dogmatism is one of the factors that have a negative effect on wellbeing. Religious dogmatism is the most dangerous factor against wellbeing. Dogmatic individuals have an inflexible cognitive system that emerges as a stable personality trait and decreases their adjustment with environment. Affective well-being and cognitive wellbeing are affected by individual adjustment. Therefore, in dogmatic individuals with low adjustment, the decrease of affective well-being and cognitive wellbeing is inevitable. This process will result in decrease of happiness and increase of aggression.

Poor and distressed, but happy: situational and cultural moderators of the relationship between wealth and happiness

Full Text Available Evidence on the relationship between wealth and happiness is mixed, hinting that there are situational or individual factors that account for the variability in results. This paper contends that wealth is in fact related to happiness. More specifically, it is proposed that poverty –as well as other adverse situations– has an undermining effect on happiness, and that this effect is attenuated by a collectivist orientation. Analyses of variance (ANOVAs using data on happiness, wealth and culture from 197 countries, supplemented by a meta-analysis of empirical studies that explore the relationship between wealth and perceptions of happiness, support the hypothesized relationship between adversity and happiness, and the moderating effect that collectivism has on such relationship.

A collective theory of happiness: words related to the word "happiness" in Swedish online newspapers.

Garcia, Danilo; Sikström, Sverker

2013-06-01

It may be suggested that the representation of happiness in online media is collective in nature because it is a picture of happiness communicated by relatively few individuals to the masses. The present study is based on articles published in Swedish daily online newspapers in 2010; the data corpus comprises 1.5 million words. We investigated which words were most (un)common in articles containing the word "happiness" as compared with articles not containing this word. The results show that words related to people (by use of all relevant pronouns: you/me and us/them); important others (e.g., grandmother, mother); the Swedish royal wedding (e.g., Prince Daniel, Princess Victoria); and the FIFA World Cup (e.g., Zlatan, Argentina, Drogba) were highly recurrent in articles containing the word happiness. In contrast, words related to objects, such as money (e.g., millions, billions), bestselling gadgets (e.g., iPad, iPhone), and companies (e.g., Google, Windows), were predictive of contexts not recurrent with the word happiness. The results presented here are in accordance with findings in the happiness literature showing that relationships, not material things, are what make people happy. We suggest that our findings mirror a collective theory of happiness, that is, a shared picture or agreement, among members of a community, concerning what makes people happy. The fact that this representation is made public on such a large scale makes it collective in nature.

It is well known that feelings of happiness transfer between individuals through mimicry induced by vision and hearing. The evidence is inconclusive, however, as to whether happiness can be communicated through the sense of smell via chemosignals. As chemosignals are a known medium for transferring negative emotions from a sender to a receiver, we examined whether chemosignals are also involved in the transmission of positive emotions. Positive emotions are important for overall well-being and yet relatively neglected in research on chemosignaling, arguably because of the stronger survival benefits linked with negative emotions. We observed that exposure to body odor collected from senders of chemosignals in a happy state induced a facial expression and perceptual-processing style indicative of happiness in the receivers of those signals. Our findings suggest that not only negative affect but also a positive state (happiness) can be transferred by means of odors. © The Author(s) 2015.

Culture is an important factor affecting happiness. This paper examines the predictive power of cultural factors on the cross-country differences in happiness and explores how different dimensions of cultural indices differ in their effects on happiness. Our empirical results show that the global leadership and organizational behavior effectiveness nine culture indices are all significantly related with happiness. Out of these nine indices, power distance (PDI) and gender egalitarianism (GEI) play the most important and stable role in determining subjective well-being (SWB). We further examine the relative importance of the various variables in contributing to the R-squared of the regression. The results show that PDI is the most important, accounting for 50 % of the contributions to R-squared of all variables, or equalling the combined contributions of income, population density and four other traditional variables. The contribution of GEI is 37.1 %, also well surpassing other variables. Our results remain robust even taking account of the different data for culture and SWB.

Does solar activity affect human happiness?

We investigate the direct influence of solar activity (represented by sunspot numbers) on human happiness (represented by the Twitter-based Happiness Index). We construct four models controlling for various statistical and dynamic effects of the analyzed series. The final model gives promising results. First, there is a statistically significant negative influence of solar activity on happiness which holds even after controlling for the other factors. Second, the final model, which is still rather simple, explains around 75% of variance of the Happiness Index. Third, our control variables contribute significantly as well: happiness is higher in no sunspots days, happiness is strongly persistent, there are strong intra-week cycles and happiness peaks during holidays. Our results strongly contribute to the topical literature and they provide evidence of unique utility of the online data.

Nicotine response and nicotinic receptors in long-sleep and short-sleep mice.

Science.gov (United States)

De Fiebre, C M; Medhurst, L J; Collins, A C

1987-01-01

Nicotine response and nicotinic receptor binding were characterized in long-sleep (LS) and short-sleep (SS) mice which have been selectively bred for differential "sleep-time" following ethanol administration. LS mice are more sensitive than SS mice to nicotine as measured by a battery of behavioral and physiological tests and as measured by sensitivity to nicotine-induced seizures. The greater sensitivity of the LS mice is not due to differences in binding of [3H]nicotine. Unlike inbred mouse strains which differ in sensitivity to nicotine-induced seizures, these selected mouse lines do not differ in levels of binding of [125I]alpha-bungarotoxin (BTX) in the hippocampus. Significant differences in BTX binding were found in the cerebellum and striatum. Although these two mouse lines do not differ in blood levels of nicotine following nicotine administration, they differ slightly in brain levels of nicotine indicating differential distribution of the drug. Since this distribution difference is much smaller than the observed behavioral differences, these mice probably differ in CNS sensitivity to nicotine; however, follow-up studies are necessary to test whether the differential response of these mice is due to subtle differences in distribution of nicotine to the brain.

The banning of sales of nicotine e-liquid in e-cigarette shops has been implemented in several states in Malaysia. The distribution of nicotine e-liquid can only be allowed by licensed pharmacies or registered medical practitioners. This study aimed to evaluate e-cigarette users' responses to the control policy in a cross-sectional survey of 851 e-cigarette users by utilizing a self-report questionnaire that assessed (1) attitudes on regulation policy of e-cigarette banning; (2) e-cigarette use behaviors; and (3) sources of e-liquid after the regulation policy has been implemented. Participants from the state of Selangor where the banning policy was implemented were surveyed. The majority (95.8%) opposed the banning and believed e-cigarettes should be sold to anyone aged 18 years or above as with tobacco cigarettes, only a minority believed that nicotine e-liquid should only be available for sale over the counter in pharmacy stores (14.6%) and in clinics with a doctor's prescription (11.8%). The majority (44.2%) reported that they would continue their e-cigarette use as before the banning policy, while 20% plan to completely stop e-cigarette usage without replacing it with any alternatives. The vast majority (87.9%) was still able to obtained nicotine e-liquid from e-cigarette shops in spite of the ban and the second most common source was from online purchase (63.1%). The sales of nicotine e-liquid from black-market were evidenced as many reported obtaining zero nicotine e-liquid from the black market (54.4%). Self- or home-made (30.8%) nicotine e-liquid was also reported. Majority of respondents that self-made e-liquid were from the average monthly income group (below MYR3000). Obtaining nicotine from the pharmacy was least preferred (21.4%). Provision of professional advice to nicotine e-liquid users along with the ban may lessen the likelihood of users switching to tobacco cigarettes or other nicotine alternatives.

Full Text Available Nicotine self-administration (SA is maintained by several variables, including the reinforcing properties of nicotine-paired cues and the nicotine-induced amplification of those cue properties. The nucleus accumbens (NAc is implicated in mediating the influence of these variables, though the underlying neurophysiological mechanisms are not yet understood. In the present study, Long-Evans rats were trained to self-administer nicotine. During SA sessions each press of a lever was followed by an intravenous infusion of nicotine (30 µg/kg paired with a combined light-tone cue. Extracellular recordings of single-neuron activity showed that 20% of neurons exhibited a phasic change in firing during the nicotine-directed operant, the light-tone cue, or both. The phasic change in firing for 98% of neurons was an increase. Sixty-two percent of NAc neurons additionally or alternatively showed a sustained decrease in average firing during the SA session relative to a presession baseline period. These session decreases in firing were significantly less prevalent in a group of neurons that were activated during either the operant or the cue than in a group of neurons that were nonresponsive during those events (referred to as task-activated and task-nonactivated neurons, respectively. Moreover, the session decrease in firing was dose-dependent for only the task-nonactivated neurons. The data of the present investigation provide supportive correlational evidence for two hypotheses: (1 excitatory neurophysiological mechanisms mediate the NAc role in cue-maintenance of nicotine SA, and (2 a differential nicotine-induced inhibition of task-activated and task-nonactivated neurons mediates the NAc role in nicotine-induced amplification of cue effects on nicotine SA.

Happy-People-Pills for All

Full Text Available

It is argued that we have a moral duty to create, and make available, advanced pharmacological agents to boost the happiness of those in the normal, i.e., the non-depressed, range of happiness. Happiness, conceived as a propensity to positive moods, is a quantitative trait with a sizeable genetic component. One means to boost the happiness of those in the normal range is to test the efficacy of antidepressants for enhancement. A second possibility is to model new pharmacologicals based on the genetics of the happiest amongst us, that is, the hyperthymic. The suggestion, in other words, is to “reverse engineer” the hyperthymic: to investigate what makes the hyperthymic genetically and physiologically different and then put what they have into pill form. To the ‘Brave New World’ objection, that there is more to wellbeing than happiness and that taking happy-people-pills will require the sacrifice of these other aspects of wellbeing, it is countered that contemporary social science research supports the view that happiness promotes achievement in the ‘higher’ endeavors of humanity, including work, love and virtue. In other words, happiness promotes acquisition of traits valued by perfectionists. Those born with genes for hyperthymia, on average, tend to be doubly blessed: they are happier and achieve more than the rest of the population. Happy-people-pills are a means to allow everyone else to share in this good

The human mind is capable of creating an internal world--the psychic sphere--including the phenomena characteristic of human nature, such as selfconsciousness, conscious experiences, conceptual thinking, symbolic language, dreams, art, creation of culture, sense of values, interest in the distant past and care about the distant future. According to the exceptionally concordant opinions of the sages and scholars of the East and the West it is just within this internal world that human happiness dwells. Happiness is a state of the spirit which consists in: internal peace, satisfaction with one's life, the joy of life, benevolence and cordiality towards oneself and towards others; sensitivity to the beauty of nature, culture and art; harmonious co-existence with the surroundings. The achievement and experiencing of the states of thus understood happiness depend mainly on ourselves and, similarly to the project of health promotion, require knowledge, willingness and possibilities. Happiness Promotion denotes the commendation and popularizing of a certain definite way of thinking and acting--showing the road which leads to the frequent experiencing of happy moments.

Nicotinic plant poisoning.

2009-09-01

A wide range of plants contain nicotinic and nicotinic-like alkaloids. Of this diverse group, those that have been reported to cause human poisoning appear to have similar mechanisms of toxicity and presenting patients therefore have comparable toxidromes. This review describes the taxonomy and principal alkaloids of plants that contain nicotinic and nicotinic-like alkaloids, with particular focus on those that are toxic to humans. The toxicokinetics and mechanisms of toxicity of these alkaloids are reviewed and the clinical features and management of poisoning due to these plants are described. This review was compiled by systematically searching OVID MEDLINE and ISI Web of Science. This identified 9,456 papers, excluding duplicates, all of which were screened. Reviewed plants and their principal alkaloids. Plants containing nicotine and nicotine-like alkaloids that have been reported to be poisonous to humans include Conium maculatum, Nicotiana glauca and Nicotiana tabacum, Laburnum anagyroides, and Caulophyllum thalictroides. They contain the toxic alkaloids nicotine, anabasine, cytisine, n-methylcytisine, coniine, n-methylconiine, and gamma-coniceine. These alkaloids act agonistically at nicotinic-type acetylcholine (cholinergic) receptors (nAChRs). The nicotinic-type acetylcholine receptor can vary both in its subunit composition and in its distribution within the body (the central and autonomic nervous systems, the neuromuscular junctions, and the adrenal medulla). Agonistic interaction at these variable sites may explain why the alkaloids have diverse effects depending on the administered dose and duration of exposure. Nicotine and nicotine-like alkaloids are absorbed readily across all routes of exposure and are rapidly and widely distributed, readily traversing the blood-brain barrier and the placenta, and are freely distributed in breast milk. Metabolism occurs predominantly in the liver followed by rapid renal elimination. Following acute exposure

On the economics of happiness: the influence of income and non-income factors on happiness

Full Text Available The quest for individual happiness and a better life for all is an important economic objective in countries as different as South Africa and France or Zimbabwe and Bhutan. Economists have focused attention on the effects of consumption, income and economic growth or development on well-being and whether economic growth can be the sole basis for delivering prosperity (Dutt & Radcliff , 2009; Jackson, 2010.  The search for happiness is an important individual and national economic goal.  In the Benthamite utilitarian tradition, happiness is the sum of all pleasures and pains. People often obtain or perceive their happiness from what they have in comparison with others.  At the macroeconomic level, more happiness may come from a sustained growth in GDP that enables households to enjoy an improved quality of life, with rising income, consumption and employment opportunities.  At the microeconomic or individual level, more income may also enable people to live happier and fuller lives relative to those who are poor.  But this accounts for only a small contribution to happiness. Life circumstances, such as marital status, health, having children and the nature of the working environment statistically make a greater contribution to happiness than income.

Anxious or Depressed and Still Happy?

A sample of 2142 adults aged 18-65, consisting of healthy controls and persons with current or past emotional disorder according to DSM-IV criteria completed self-ratings for happiness and emotional well-being and symptom severity. Lagged measurements of personality, symptom severity and presence of anxiety and depressive disorder at T0 (year 0, T2 (year 2 and T4 (year 4 were used to predict happiness and emotional well-being at T6 (year 6 controlling for demographics. In particular persons with more depressive symptoms, major depressive disorder, social anxiety disorder and comorbid emotional disorders reported lower levels of happiness and emotional well-being. Depression symptom severity and to a lesser extent depressive disorder predicted future happiness and emotional well-being at T6. Extraversion and to a lesser extent neuroticism also consistently forecasted future happiness and emotional well-being independent of concurrent lagged measurements of emotional disorders and symptoms. A study limitation is that we only measured happiness and emotional well-being at T6 and our measures were confined to hedonistic well-being and did not include psychological and social well-being. In sum, consistent with the two continua model of emotional well-being and mental illness, a 'happy' personality characterized by high extraversion and to a lesser extent low neuroticism forecasts future happiness and emotional well-being independent of concurrently measured emotional disorders or symptom severity levels. Boosting positive emotionality may be an important treatment goal for persons

(±)-Modafinil (MOD) is used clinically for the treatment of sleep disorders and has been investigated as a potential medication for the treatment of psychostimulant addiction. However, the therapeutic efficacy of (±)-MOD for addiction is inconclusive. Herein we used animal models of self-administration and in vivo microdialysis to study the pharmacological actions of R-modafinil (R-MOD) and S-modafinil (S-MOD) on nicotine-taking and nicotine-seeking behavior, and mechanisms underlying such actions. We found that R-MOD is more potent and effective than S-MOD in attenuating nicotine self-administration in Long–Evans rats. As Long–Evans rats did not show a robust reinstatement response to nicotine, we used alcohol-preferring rats (P-rats) that display much higher reinstatement responses to nicotine than Long–Evans rats. We found that R-MOD significantly inhibited intravenous nicotine self-administration, nicotine-induced reinstatement, and nicotine-associated cue-induced drug-seeking behavior in P-rats. R-MOD alone neither sustained self-administration in P-rats previously self-administering nicotine nor reinstated extinguished nicotine-seeking behavior. The in vivo brain microdialysis assays demonstrated that R-MOD alone produced a slow-onset moderate increase in extracellular DA. Pretreatment with R-MOD dose-dependently blocked nicotine-induced dopamine (DA) release in the nucleus accumbens (NAc) in both naive and nicotine self-administrating rats, suggesting a DA-dependent mechanism underlying mitigation of nicotine's effects. In conclusion, the present findings support further investigation of R-MOD for treatment of nicotine dependence in humans. PMID:25613829

Cigarette smoke (CS) exposure during pregnancy can lead to profound adverse effects on fetal development. Although CS contains several thousand chemicals, nicotine has been widely used as its surrogate as well as in its own right as a neuroteratogen. The justification for the route and dose of nicotine administration is largely based on inferential data suggesting that nicotine 6 mg/kg/day infused continuously via osmotic mini pumps (OMP) would mimic maternal CS exposure. We provide evidence that 6 mg/kg/day nicotine dose as commonly administered to pregnant rats leads to plasma nicotine concentrations that are 3-10-fold higher than those observed in moderate to heavy smokers and pregnant mothers, respectively. Furthermore, the cumulative daily nicotine dose exceeds by several hundred fold the amount consumed by human heavy smokers. Our study does not support the widely accepted notion that regardless of the nicotine dose, a linear nicotine dose-concentration relationship exists in a steady-state OMP model. We also show that total nicotine clearance increases with advancing pregnancy but no significant change is observed between the 2nd and 3rd trimester. Furthermore, nicotine infusion even at this extremely high dose has little effect on a number of maternal and fetal biologic variables and pregnancy outcome suggesting that CS constituents other than nicotine mediate the fetal growth restriction in infants born to smoking mothers. Our current study has major implications for translational research in developmental toxicology and pharmacotherapy using nicotine replacement treatment as an aid to cessation of cigarette smoking in pregnant mothers

In the 18th century, the Enlightenment ushered in the notion that happiness was the attainment of a worthy life. Since then the pursuit of happiness has spread to every aspect of behavior, from religion and politics to work and parenting. Today the happiness imperative creates pressures that, paradoxically, can make us miserable. Sadness is often mistaken for a pathology. Understanding the cultural commitment to good cheer as an artifact of modern history, not as an inherent feature of the human condition, opens new opportunities for understanding key facets of our social and personal experience.

Happiness: before and after the kids.

Understanding how having children influences parents' subjective well-being ("happiness") has great potential to explain fertility behavior. We study parental happiness trajectories before and after the birth of a child, using large British and German longitudinal data sets. We account for unobserved parental characteristics using fixed-effects models and study how sociodemographic factors modify the parental happiness trajectories. Consistent with existing work, we find that happiness increases in the years around the birth of a first child and then decreases to before-child levels. Moreover, happiness increases before birth, suggesting that the trajectories may capture not only the effect of the birth but also the broader process of childbearing, which may include partnership formation and quality. Sociodemographic factors strongly modify this pattern. Those who have children at older ages or who have more education have a particularly positive happiness response to a first birth; and although having the first two children increases happiness, having a third child does not. The results, which are similar in Britain and Germany, suggest that having up to two children increases happiness, and mostly for those who have postponed childbearing. This pattern is consistent with the fertility behavior that emerged during the second demographic transition and provides new insights into low and late fertility.

Happiness is a subjective experience that is an ultimate goal for humans. Psychological studies have shown that subjective happiness can be measured reliably and consists of emotional and cognitive components. However, the neural substrates of subjective happiness remain unclear. To investigate this issue, we used structural magnetic resonance imaging and questionnaires that assessed subjective happiness, the intensity of positive and negative emotional experiences, and purpose in life. We found a positive relationship between the subjective happiness score and gray matter volume in the right precuneus. Moreover, the same region showed an association with the combined positive and negative emotional intensity and purpose in life scores. Our findings suggest that the precuneus mediates subjective happiness by integrating the emotional and cognitive components of happiness.

2008-09-01

This study, based on data collected in 2005 from Chai Nat province, examines the level of happiness of the Thai elderly population and its relationship to various external and internal factors. It was found that mean happiness was slightly above a feeling of "neutral." According to multiple regression analyses, external factors including economic hardship, living arrangements, functional ability, perceived social environment, and consumerism significantly influence the level of happiness. The strongest predictor of happiness is, however, the internal factor-that is, a feeling of relative poverty when compared to their neighbors. Controlling for demographic and all external factors, the respondents who do not feel poor show the highest level of happiness compared to those who feel as poor as or poorer than their neighbors. This is self-interpreted as a feeling of contentment with what one has, which has been influenced by Thai culture, which is pervaded by Buddhism.

The ability to know emotional states for large number of people is important, for example, to ensure the effectiveness of public policies. In this study, we propose a measure of happiness that can be used in large scale population that is based on the analysis of Indonesian language lexicons. Here, we incorporate human assessment of Indonesian words, then quantify happiness on large-scale of texts gathered from twitter conversations. We used two psychological constructs to measure happiness: valence and arousal. We found that Indonesian words have tendency towards positive emotions. We also identified several happiness patterns during days of the week, hours of the day, and selected conversation topics.

Perceived parental behaviour, self-esteem and happiness.

Furnham, A; Cheng, H

2000-10-01

This study set out to determine to what extent recalled parental rearing styles (authoritarian, authoritativeness, permissiveness), personality (extraversion, neuroticism, psychoticism, lie), and self-esteem predicted self-rated happiness in a normal, nonclinical, population of young people in their late teens and early 20s. Each participant completed a few questionnaires: the Eysenck Personality Questionnaire (revised), the Rosenberg Self-Esteem Scale, the Parental Authority Questionnaire and the Oxford Happiness Inventory. It was predicted that sex, extraversion, neuroticism, self-esteem and both maternal and paternal authoritativeness would be significant predictors of happiness. Regressional and path analysis showed self-esteem to be the most dominant and powerful predictor of happiness. The effect of sex on happiness was moderated by neuroticism, which related to self-esteem, which directly influenced happiness. Stability, extraversion and maternal authoritativeness were significant predictors of self-esteem accounting for one-third of the variance. The results are considered in terms of the distinct literature on the relation between personality and happiness and on the relation between parental styles and self-esteem. Self-esteem was both a direct and a moderator variable for young people's self-reported happiness. Extraversion had both direct and indirect predictive power of happiness, whereas neuroticism predicted happiness mediating through self-esteem. Maternal authoritativeness was the only direct predictor of happiness when paternal and maternal rearing styles were examined together, suggesting that a reasonable discipline exercised by mothers towards their children was particularly beneficial in enhancing the offsprings' self-esteem.

Health or Happiness? A Note on Trading Off Health and Happiness in Rationing Decisions.

2016-01-01

Economic evaluations typically value the effects of an intervention in terms of quality-adjusted life-years, which combine length and health-related quality of life. It has been suggested that economic evaluations should incorporate broader outcomes than health-related quality of life. Broader well-being, for instance measured as happiness, could be a better measure of the overall welfare effects in patients because of treatment. An underexplored question is whether and how people trade off information on health and broader outcomes from treatment in rationing decisions. This article presents the results of a first experiment aimed at exploring such trade-offs between health and happiness. We used a Web-based questionnaire in a representative sample of the public from the Netherlands (N = 1015). People made choices between two groups of patients differing in terms of their health and happiness levels before treatment and gains from treatment. The results showed that about half the respondents were willing to discriminate between patient groups on the basis of their health and happiness levels before and after treatment. In the trader group, health gains were considered somewhat more important than happiness gains. Our findings suggest that both health and happiness levels of patients may play a role in priority setting. Copyright © 2016 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

2016-10-01

In this paper, we examine the relations between the daily happiness sentiment extracted from Twitter and the stock market performance in 11 international stock markets. By partitioning this happiness sentiment into quintiles from the least to the happiest days, we first show that the contemporary correlation coefficients between happiness sentiment and index return in the 4 and most-happiness subgroups are higher than that in least, 2 and 3-happiness subgroups. Secondly, the happiness sentiment can provide additional explanatory power for index return in the most-happiness subgroup. Thirdly, the daily happiness can granger-cause the changes in index return for the majority of stock markets. Fourthly, we find that the index return and the range-based volatility of the most-happiness subgroup are larger than those of other subgroups. These results highlight the important role of social media in stock market.

General Practitioners' views on the provision of nicotine replacement therapy and bupropion

2001-10-01

Full Text Available Abstract Background Nicotine replacement therapies (NRT and a new drug, bupropion, are licensed in several countries as aids to smoking cessation. General practitioners (GPs play a crucial role in recommending or prescribing these medications. In the UK there has been discussion about whether the medications should be reimbursable by the National Health Service (NHS. This study assessed English GPs' attitudes towards reimbursement of NRT and bupropion. Methods Postal survey of a randomly selected national sample of GPs; 376 GPs completed the questionnaire after one reminder; effective response rate: 53%. There was no difference between the responses of GPs who responded to the initial request and those who responded only after a reminder suggesting minimal bias due to non-response. Results Attitudes of GPs were remarkably divided on most issues relating to the medications. Forty-three percent thought that bupropion should not be on NHS prescription while 42% thought that it should be (15% did not know; Fifty percent thought that NRT should not be on NHS prescription while 42% thought it should be (8% did not know. Requiring that smokers attend behavioural support programmes to be eligible to receive the medications on NHS prescription made no appreciable difference to the GPs' views. GPs were similarly divided on whether having the medications reimbursable would add unacceptably to their workload or offer a welcome opportunity to discuss smoking with their patients. A principal components analysis of responses to the individual questions on NRT and bupropion revealed that GPs' attitudes could be understood in terms of a single 'pro-con' dimension accounting for 53% of the total variance which made no distinction between the two medications. Conclusions GPs in England appear to be divided in their attitudes to medications to aid smoking cessation and appear not to discriminate in their views between different types of medication or different

African American (AA) smokers experience greater tobacco-related disease burden than Whites, despite smoking fewer cigarettes per day (CPD). Understanding factors that influence daily nicotine intake in AA smokers is an important step toward decreasing tobacco-related health disparities. One factor of interest is smoking topography, or the study of puffing behavior. (i) to create a model using puff characteristics, nicotine dependence, and nicotine metabolism to predict daily nicotine exposure, and (ii) to compare puff characteristics and nicotine intake from two cigarettes smoked at different times to ensure the reliability of the puff characteristics included in our model. Sixty AA smokers smoked their preferred brand of cigarette at two time points through a topography device. Plasma nicotine, expired CO, and changes in subjective measures were measured before and after each cigarette. Total nicotine equivalents (TNE) was measured from 24-hour urine collected during ad libitum smoking. In a model predicting daily nicotine exposure, total puff volume, CPD, sex, and menthol status were significant predictors (R(2) = 0.44, P smokers.

To assess the long-term efficacy of a fully automated digital multi-media smoking cessation intervention. Two-arm randomized control trial (RCT). Setting World Wide Web (WWW) study based in Norway. Subjects (n = 396) were recruited via internet advertisements and assigned randomly to conditions. Inclusion criteria were willingness to quit smoking and being aged 18 years or older. The treatment group received the internet- and cell-phone-based Happy Ending intervention. The intervention programme lasted 54 weeks and consisted of more than 400 contacts by e-mail, web-pages, interactive voice response (IVR) and short message service (SMS) technology. The control group received a self-help booklet. Additionally, both groups were offered free nicotine replacement therapy (NRT). Abstinence was defined as 'not even a puff of smoke, for the last 7 days', and assessed by means of internet surveys or telephone interviews. The main outcome was repeated point abstinence at 1, 3, 6 and 12 months following cessation. Participants in the treatment group reported clinically and statistically significantly higher repeated point abstinence rates than control participants [22.3% versus 13.1%; odds ratio (OR) = 1.91, 95% confidence interval (CI): 1.12-3.26, P = 0.02; intent-to-treat). Improved adherence to NRT and a higher level of post-cessation self-efficacy were observed in the treatment group compared with the control group. As the first RCT documenting the long-term treatment effects of such an intervention, this study adds to the promise of digital media in supporting behaviour change.

Delivering nicotine in the way smokers seek is likely to be the key factor in e-cigarette (EC) success in replacing cigarettes. We examined to what degree different types of EC mimic nicotine intake from cigarettes. Twelve participants ('dual users' of EC and cigarettes) used their own brand cigarette and nine different EC brands. Blood samples were taken at baseline and at 2-min intervals for 10 min and again at 30 min. Eleven smokers provided usable data. None of the EC matched cigarettes in nicotine delivery (C max  = 17.9 ng/ml, T max  = 4 min and AUC 0->30  = 315 ng/ml/min). The EC with 48 mg/ml nicotine generated the closest PK profile (C max  = 13.6 ng/ml, T max  = 4 min, AUC 0->30  = 245 ng/ml/min), followed by a third generation EC using 20 mg/ml nicotine (C max  = 11.9 ng/ml, T max  = 6 min, AUC 0->30  = 232 ng/ml/min), followed by the tank system using 20 mg/ml nicotine (C max  = 9.9 ng/ml, T max  = 6 min, AUC 0->30  = 201 ng/ml/min). Cig-a-like PK values were similar, ranging from C max 7.5 to 9.7 ng/ml, T max 4-6 min, and AUC 0->30 144 to 173 ng/ml/min. Moderate differences in e-liquid nicotine concentrations had little effect on nicotine delivery, e.g. the EC with 24 mg/ml cartridge had the same PK profile as ECs with 16 mg/ml cartridges. Using similar strength e-liquid, the tank EC provided significantly more nicotine than cig-a-like ECs. EC brands we tested do not deliver nicotine as efficiently as cigarettes, but newer EC products deliver nicotine more efficiently than cig-a-like brands. Moderate variations in nicotine content of e-liquid have little effect on nicotine delivery. Smokers who are finding cig-a-like EC unsatisfactory should be advised to try more advanced systems.

Moderation of Nicotine Effects on Covert Orienting of Attention Tasks by Poor Placebo Performance and Cue Validity

Gilbert, David G.; Rzetelny, Adam; Rabinovich, Norka E.

2016-01-01

Introduction and Rationale Given baseline-dependent effects of nicotine on other forms of attention, there is reason to believe that inconsistent findings for the effects of nicotine on attentional orienting may be partly due to individual differences in baseline (abstinence state) functioning. Individuals with low baseline attention may benefit more from nicotine replacement. Method The effects of nicotine as a function of baseline performance (bottom, middle, and top third of mean reaction times during placebo) were assessed in 52 habitual abstinent smokers (26 females/26 males) utilizing an arrow-cued covert orienting of attention task. Results Compared to a placebo patch, a 14 mg nicotine patch produced faster overall reaction times (RTs). In addition, individuals with slower RTs during the placebo condition benefitted more from nicotine on cued trials than did those who had shorter (faster) RTs during placebo. Nicotine also enhanced the validity effect (shorter RTs to validly vs. invalidly cued targets), but this nicotine benefit did not differ as a function of overall placebo-baseline performance. Conclusions These findings support the view that nicotine enhances cued spatial attentional orienting in individuals who have slower RTs during placebo (nicotine-free) conditions; however, baseline-dependent effects may not generalize to all aspects of spatial attention. These findings are consistent with findings indicating that nicotine’s effects vary as a function of task parameters rather than simple RT speeding or cognitive enhancement. PMID:27461547

Objectives We aimed to examine the associations of both objectively assessed and perceived physical and social neighborhood characteristics with happiness in European adults. In addition, we aimed to study how these associations differed among subgroups. Methods Participants (N = 6037) of the cross-sectional SPOTLIGHT survey reported on their level of happiness using a 5-point Likert scale, and on perceived physical and social environmental neighborhood characteristics. Objective physical environmental characteristics were assessed using a Google Street View-based neighborhood audit. Associations of 14 physical and social environmental characteristics with happiness were analyzed using multivariable multinomial regression analyses with clustered standard errors. Results Living in neighborhoods with higher levels of aesthetics and more water and green space was associated with being very happy. Individuals who perceived their neighborhood to be safer, more functional and more aesthetic were more likely to be very happy. The associations of functionality and aesthetics with happiness were strongest in the Ghent region (Belgium), the Randstad (the Netherlands) and Greater London (United Kingdom). Perceived absence of air pollution was only associated with higher levels of happiness in more highly educated participants. Individuals with a larger social network, more social cohesion and who trusted their neighbors were more likely to be very happy. The association between social networks and happiness was somewhat stronger in men than in women. In general, the associations between environmental characteristics and happiness had similar directions and sizes across socio-economic and socio-demographic subgroups. Conclusions This European study provided evidence that both objectively assessed and perceived physical and social characteristics of the neighborhood environment are associated with the happiness of its residents.

Recent evidence suggests an involvement of T-type calcium channels in the effects of drugs of abuse. We examined the influence of the novel, potent, and selective T-type calcium channel antagonist [2-(4-cyclopropylphenyl)-N-((1R)-1-{5-[2,2,2-trifluoroethyl]oxo}pyridine-2-yl)ethyl]acetamide] (TTA-A2) (.3, 1, or 3 mg/kg) on motivation for nicotine, as measured by nicotine self-administration on a progressive ratio (PR) schedule, and nicotine- and cue-induced reinstatement for a response previously reinforced with nicotine delivery (n = 11 or 12 Long Evans rats/group). Furthermore, we examined the specificity of the TTA-A2 effects by characterizing its influence on PR responding for food (in the absence or presence of nicotine-potentiated responding), food- versus nicotine-induced cue-potentiated reinstatement for a response previously reinforced by food administration (n = 11 or 12 Wistar Hannover rats/group), and its ability to induce a conditioned place aversion. TTA-A2 dose-dependently decreased self-administration of nicotine on a PR schedule and the ability of both nicotine and a cue paired with nicotine to reinstate responding. The effects were specific for nicotine's incentive motivational properties, as TTA-A2 did not influence responding for food on a PR schedule but did attenuate the ability of nicotine to potentiate responding for food. Likewise, TTA-A2 did not alter food-induced cue-potentiated reinstatement for a response previously reinforced by food but did decrease nicotine-induced cue-potentiated reinstatement. Finally, TTA-A2 did not produce an aversive state, as indicated by a lack of ability to induce conditioned place aversion. These data suggest that T-type calcium channel antagonists have potential for alleviating nicotine addiction by selectively decreasing the incentive motivational properties of nicotine.

Knowledge about the change in blood nicotine concentrations during the first five minutes (acute phase) of e-cigarette vaping is important to determine whether the used product has a dependence potential or may be an efficient nicotine replacement product. To address this issue, we monitored blood nicotine levels during the acute phase in volunteers using disposable cigalikes (CLs) and a tank model (TM) and compared them with blood nicotine levels in subjects using a tobacco cigarette (TC). In parallel, heart rate changes were continually measured and withdrawal symptoms and craving were assessed with the Questionnaire on Smoking Urges before and immediately after the vaping/smoking sessions. Additionally, at the end of each session negative health effects were rated on a visual analog scale. After five minutes of e-cigarette or TC use, the mean nicotine plasma concentrations were as follows: CLs, 5.5ng/ml; TM, 9.3ng/ml; TC, 17.1ng/ml. Nicotine levels increased significantly faster in the first 4min of consuming a TC than with the CLs and the TM. The highest rate of increase in nicotine concentration was found with the TC (6.8ng/ml) and TM (2.3ng/ml) between the 1st and 2nd minute, whereas the CLs showed comparatively small changes in the amount delivered over the five minutes. Withdrawal and craving for smoking decreased with the TM by the same amount as with the TC, even though less nicotine was delivered to the blood and considerably fewer side effects occurred. The heart rate of TM users was also markedly lower than that of the TC users. Unlike CLs, TM e-cigarettes represent an effective source of nicotine and might be used as an alternative nicotine replacement product to aid smoking cessation. However, nicotine plasma levels observed in TM users after short-time vaping have also the potential to produce and sustain nicotine addiction. Copyright © 2017 Elsevier GmbH. All rights reserved.

Full Text Available Introduction: Facial deformities and aesthetic and functional anomalies in children may be a cause of real distress in families. Problems faced by parents in coping with a child’s anomaly can be upsetting and lead parents to exhibit over-severe behavior. The present study was conducted in order to study the effect of happiness program on the happiness of the mothers of children with a cleft lip and palate.   Materials and Methods: In this semi-experimental study, 64 mothers of children with a cleft lip and palate enrolled by convenience random sampling were assigned to an intervention or control group based on a simple random sampling. Then, a program of happiness training was implemented consisting of 10 sessions of 2 hours each. A demographic questionnaire and the Oxford Happiness Questionnaire were completed prior to and 2 months after the last session of intervention. The data were analyzed using descriptive and analytical statistics, consisting of a paired t-test, independent t-test and Chi-square test using SPSS version 20.   Results: The independent t-test indicated a significant difference in mean happiness score after training between the intervention and control groups (P0.05.   Conclusion: In light of the efficacy of happiness training on the promotion of happiness in the mothers of children with a cleft lip and palate, this model is recommended as a healthcare intervention to decrease stress in mothers following the birth of an infant with a cleft lip and palate.

Problems faced by parents in coping with a child's anomaly can be upsetting and lead parents to exhibit over-severe behavior. The present study was conducted in order to study the effect of happiness program on the happiness of the mothers of children with a cleft lip and palate. In this semi-experimental study, 64 mothers of children with a cleft lip and palate enrolled by convenience random sampling were assigned to an intervention or control group based on a simple random sampling. Then, a program of happiness training was implemented consisting of 10 sessions of 2 hours each. A demographic questionnaire and the Oxford Happiness Questionnaire were completed prior to and 2 months after the last session of intervention. The data were analyzed using descriptive and analytical statistics, consisting of a paired t-test, independent t-test and Chi-square test using SPSS version 20. The independent t-test indicated a significant difference in mean happiness score after training between the intervention and control groups (Phappiness score between before and after training in the intervention group, although the difference was not statistically significant for the control group (P>0.05). In light of the efficacy of happiness training on the promotion of happiness in the mothers of children with a cleft lip and palate, this model is recommended as a healthcare intervention to decrease stress in mothers following the birth of an infant with a cleft lip and palate.

Nicotine Withdrawal Disrupts Contextual Learning but Not Recall of Prior Contextual Associations: Implications for Nicotine Addiction

Interactions between nicotine and learning could contribute to nicotine addiction. Although previous research indicates that nicotine withdrawal disrupts contextual learning, the effects of nicotine withdrawal on contextual memories acquired before withdrawal are unknown. The present study investigated whether nicotine withdrawal disrupted recall of prior contextual memories by examining the effects of nicotine withdrawal on recall of nicotine conditioned place preference (CPP) and contextual...

Thermochemical Properties of Nicotine Salts

Full Text Available The thermal gravimetric analysis (TGA and differential scanning calorimetry (DSC results presented in this report clearly show that the thermal stability and the endothermic peak nicotine release temperatures are different for different nicotine salts and these temperatures appear to be linked to the general microstructural details of the salt itself. In addition, the peak nicotine release temperatures are highly dependent upon the sample size used. The heat of vaporization for neat (non-protonated nicotine is also sample-size dependent. The TGA data showed that the least stable of the salts tested at elevated temperatures was the liquid salt nicotine triacetate followed by the crystalline materials (e.g., nicotine gallate and finally, the amorphous salts (e.g., nicotine alginate. The DSC results revealed that the liquid and crystalline salts exhibit nicotine release endotherms that are strongly related to the sample weight being tested. The amorphous salts show nicotine endotherm peak temperatures that are nearly independent of the sample weight. The range of peak nicotine release temperatures varied depending upon the specific salts and the sample size from 83 oC to well over 200 oC. Based on these results, the evolution of nicotine from the nicotine salt should be expected to vary based on the composition of the salt, the details of its microstructure, and the amount of nicotine salt tested.

Mental health disorders are major contributors to the global burden of disease and their inverse relationship with physical activity is widely accepted. However, research on the association between physical activity and positive mental health outcomes is limited. Happiness is an example of a positive construct of mental health that may be promoted by physical activity and could increase resilience to emotional perturbations. The aim of this study is to use a large multi-country dataset to assess the association of happiness with physical activity volume and its specificity to intensity and/or activity domain. We analysed Eurobarometer 2002 data from 15 countries (n = 11,637). This comprised one question assessing self-reported happiness on a six point scale (dichotomised: happy/unhappy) and physical activity data collected using the IPAQ-short (i.e. walking, moderate, vigorous) and four domain specific items (i.e. domestic, leisure, transport, vocation). Logistic regression was used to examine the association between happiness and physical activity volume adjusted for sex, age, country, general health, relationship status, employment and education. Analyses of intensity and domain specificity were assessed by logistic regression adjusted for the same covariates and physical activity volume. When compared to inactive people, there was a positive dose-response association between physical activity volume and happiness (highly active: OR = 1.52 [1.28-1.80]; sufficiently active: OR = 1.29 [1.11-1.49]; insufficiently active: OR = 1.20 [1.03-1.39]). There were small positive associations with happiness for walking (OR = 1.02 [1.00-1.03]) and vigorous-intensity physical activity (OR = 1.03 [1.01-1.05). Moderate-intensity physical activity was not associated with happiness (OR = 1.01 [0.99-1.03]). The strongest domain specific associations with happiness were found for "a lot" of domestic (OR = 1.42 [1.20-1.68]) and "some" vocational (OR = 1.33 [1.08-1.64]) physical

Happiness: The Potential Power of Environment

Full Text Available Many scientists have argued that they can determine to what extent human happiness levels are controlled by genes by comparing the average happiness levels of identical twins raised apart. If we discover that identical twins raised apart tend to be more hedonically similar than fraternal twins raised apart, this is interpreted as evidence for the thesis that genes have a strong influence on our happiness levels. If identical twins are hedonically dissimilar, as dissimilar as fraternal twins raised apart, this has been taken as evidence for the thesis that happiness levels are determined in large part by the environment. I shall show that that these interpretations of these studies rely on a set of false assumptions. There is no good evidence our genes determine how happy we can be.

Although we know much about work-related physician burnout and the subsequent negative effects, we do not fully understand work-related physician wellness. Likewise, the relation of wellness and burnout to physician happiness is unclear. The purpose of this study was to examine how physician burnout and wellness contribute to happiness. We sampled 2000 full-time physician members of the American Academy of Family Physicians. Respondents completed a demographics questionnaire, questions about workload, the Physician Wellness Inventory, the Maslach Burnout Inventory, and the Subjective Happiness Scale. We performed a hierarchical regression analysis with the burnout and wellness subscales as predictor variables and physician happiness as the outcome variable. Our response rate was 22%. Career purpose, personal accomplishment, and perception of workload manageability had significant positive correlations with physician happiness. Distress had a significant negative correlation with physician happiness. A sense of career meaning and accomplishment, along with a lack of distress, are important factors in determining physician happiness. The number of hours a physician works is not related to happiness, but the perceived ability to manage workload was significantly related to happiness. Wellness-promotion efforts could focus on assisting physicians with skills to manage the workload by eliminating unnecessary tasks or sharing workload among team members, improving feelings of work accomplishment, improving career satisfaction and meaning, and managing distress related to patient care.

Testing Happiness Hypothesis among the Elderly

Full Text Available We use a rich data set that allows us to test different happiness hypotheses employing four methodological approaches. We find that older people in Uruguay have a tendency to report themselves happy when they are married, when they have higher standards of health and when they earn higher levels of income or they consider that their income is suitable for their standard of living. On the contrary, they report lower levels of happiness when they live alone and when their nutrition is insufficient. We also find that education has no clear impact on happiness. We think that our study is a contribution to the study of those factors that can explain happiness among the elderly in Latin American countries. Future work will focus on enhanced empirical analysis and in extending our study to other countries.

Racial differences in the relationship between rate of nicotine metabolism and nicotine intake from cigarette smoking.

Rate of nicotine metabolism has been identified as an important factor influencing nicotine intake and can be estimated using the nicotine metabolite ratio (NMR), a validated biomarker of CYP2A6 enzyme activity. Individuals who metabolize nicotine faster (higher NMR) may alter their smoking behavior to titrate their nicotine intake in order to maintain similar levels of nicotine in the body compared to slower nicotine metabolizers. There are known racial differences in the rate of nicotine metabolism with African Americans on average having a slower rate of nicotine metabolism compared to Whites. The goal of this study was to determine if there are racial differences in the relationship between rate of nicotine metabolism and measures of nicotine intake assessed using multiple biomarkers of nicotine and tobacco smoke exposure. Using secondary analyses of the screening data collected in a recently completed clinical trial, treatment-seeking African American and White daily smokers (10 or more cigarettes per day) were grouped into NMR quartiles so that the races could be compared at the same NMR, even though the distribution of NMR within race differed. The results indicated that rate of nicotine metabolism was a more important factor influencing nicotine intake in White smokers. Specifically, Whites were more likely to titrate their nicotine intake based on the rate at which they metabolize nicotine. However, this relationship was not found in African Americans. Overall there was a greater step-down, linear type relationship between NMR groups and cotinine or cotinine/cigarette in African Americans, which is consistent with the idea that differences in blood cotinine levels between the African American NMR groups were primarily due to differences in CYP2A6 enzyme activity without titration of nicotine intake among faster nicotine metabolizers.

This article explores explore the relationships among socio-demographics, perceived health, and happiness in a patient population of 221 adults recruited from 39 primary care practices in Alabama. We also explored whether the relationship between socio-demographics and happiness is mediated by perceived health. The dependent variable, happiness, was dichotomized as happy versus unhappy. Independent variables or correlates of happiness included race (Black or White), age (happiness and its correlates. Our findings suggest that adequate health literacy and better perceived health are associated with an increase in the likelihood of happiness. In addition, the relationship between perceived sufficient income and happiness is mediated by perceived health; whereas, individuals with sufficient income are more likely to have better perceived health, and as a result more likely to be happy. Other individual factors, such as gender, age, and race were not significantly associated with being happy or having higher perceived health in any of the models. Results suggest that policies aimed at increasing health literacy, promoting health, and reducing income disparities may be associated with greater happiness. PMID:28757904

Chronic Nicotine Treatment During Adolescence Attenuates the Effects of Acute Nicotine in Adult Contextual Fear Learning.

Science.gov (United States)

Holliday, Erica D; Gould, Thomas J

2017-01-01

Adolescent onset of nicotine abuse is correlated with worse chances at successful abstinence in adulthood. One reason for this may be due to enduring learning deficits resulting from nicotine use during adolescence. Previous work has indicated that chronic nicotine administration beginning in late adolescence (PND38) caused learning deficits in contextual fear when tested in adulthood. The purpose of this study was to determine if chronic nicotine treatment during adolescence would alter sensitivity to nicotine's cognitive enhancing properties in adulthood. C57BL/6J mice received saline or chronic nicotine (12.6mg/kg/day) during adolescence (postnatal day 38) or adulthood (postnatal day 54) for a period of 12 days. Following a 30-day protracted abstinence, mice received either an acute injection of saline or nicotine (0.045, 0.18, and 0.36mg/kg) prior to training and testing a mouse model of contextual fear. It was found that chronic nicotine administration in adult mice did not alter sensitivity to acute nicotine following a protracted abstinence. In adolescent mice, chronic nicotine administration disrupted adult learning and decreased sensitivity to acute nicotine in adulthood as only the highest dose tested (0.36mg/kg) was able to enhance contextual fear learning. These results suggest that adolescent nicotine exposure impairs learning in adulthood, which could increase the risk for continued nicotine use in adulthood by requiring administration of higher doses of nicotine to reverse learning impairments caused by adolescent nicotine exposure. Results from this study add to the growing body of literature suggesting chronic nicotine exposure during adolescence leads to impaired learning in adulthood and demonstrates that nicotine exposure during adolescence attenuates the cognitive enhancing effects of acute nicotine in adulthood, which suggests altered cholinergic function. © The Author 2016.

Full Text Available The present study examined the relationships between dispositional approach and avoidance motives, humor styles, and happiness. In keeping with previous research, approach motives and the two positive humor styles (self-enhancing and affiliative positively correlated with happiness, whereas avoidance motives and the two negative humor styles (self-defeating and aggressive negatively correlated with happiness. Also, we found support for three new hypotheses. First, approach motives correlated positively with self-enhancing and affiliative humor styles. Second, avoidance motives correlated positively with self-defeating humor style, and third, the positive relationship between approach motives and happiness was mediated by self-enhancing humor style.

Electronic Nicotine Delivery Systems.

Electronic nicotine delivery systems (ENDS) are rapidly growing in popularity among youth. ENDS are handheld devices that produce an aerosolized mixture from a solution typically containing concentrated nicotine, flavoring chemicals, and propylene glycol to be inhaled by the user. ENDS are marketed under a variety of names, most commonly electronic cigarettes and e-cigarettes. In 2014, more youth reported using ENDS than any other tobacco product. ENDS pose health risks to both users and nonusers. Nicotine, the major psychoactive ingredient in ENDS solutions, is both highly addictive and toxic. In addition to nicotine, other toxicants, carcinogens, and metal particles have been detected in solutions and aerosols of ENDS. Nonusers are involuntarily exposed to the emissions of these devices with secondhand and thirdhand aerosol. The concentrated and often flavored nicotine in ENDS solutions poses a poisoning risk for young children. Reports of acute nicotine toxicity from US poison control centers have been increasing, with at least 1 child death reported from unintentional exposure to a nicotine-containing ENDS solution. With flavors, design, and marketing that appeal to youth, ENDS threaten to renormalize and glamorize nicotine and tobacco product use. There is a critical need for ENDS regulation, legislative action, and counter promotion to protect youth. ENDS have the potential to addict a new generation of youth to nicotine and reverse more than 50 years of progress in tobacco control. Copyright © 2015 by the American Academy of Pediatrics.

This is the first study to our knowledge to examine the relationship between happiness and longevity among a nationally representative sample of adults. We use the recently-released General Social Survey-National Death Index dataset and Cox proportional hazards models to reveal that overall happiness is related to longer lives among U.S. adults. Indeed, compared to very happy people, the risk of death over the follow-up period is 6% (95% CI 1.01-1.11) higher among individuals who are pretty happy and 14% (95% CI 1.06-1.22) higher among those who are not happy, net of marital status, socioeconomic status, census division, and religious attendance. This study provides support for happiness as a stand-alone indicator of well-being that should be used more widely in social science and health research. Copyright © 2015 Elsevier Ltd.

Pregnancy is a crisis in the human life cycle as an important turning point in aspects of anatomical, physiological and psychosocial changes. An unhappy pregnanus could influence the fetal growth and development and sense of maternal competence as well as bonding with the fetus which profoundly affect the nurture of the infant after delivery. The authors'purposes were to study happiness and related factors in pregnant women having antenatal care at King Chulalongkorn Memorial Hospital. Four hundred and thirty-eight pregnant women from the antenatal clinic at King Chulalongkorn Memorial Hospital were randomly selected to complete a set of questionnaires that consisted of personal information, pregnant information, The Oxford Happiness Questionnaire (OHQ), The Maudsley Personality Inventory (MPI) and The Marital Satisfaction Scale (MSS). Prevalence of happiness level was classified by descriptive analysis. Unpaired t-test, ANOVA and Pearson's Product Moment Correlation analyzed related factors to happiness in pregnant woman. Also Stepwise Multiple Regression Analysis was used to define predictive factors for happiness in pregnant women. The sample had a high level of happiness of 57.3%. Significant related factors to happiness were age between 31-35 years, high education level, high individual and family income, having saving deposition, no drug abuse, improved marital relationship, no conflict with relatives, extrovert and stable personality types and no concerns about post-partum body image. Four predictive factors for happiness in pregnant women were extrovert personality, stable personality, high family income and improved marital relationship. Level of happiness in pregnant women could be predicted by type of personality, family income and marital relationship.

The aim of the present study was to examine the possible role of nicotinic acetylcholine receptors of the dorsal hippocampus (CA1 regions), the medial prefrontal cortex or the basolateral amygdala in the effect of acute or sub-chronic stress on nicotine-induced conditioned place preference. Our results indicated that subcutaneous administration of nicotine (0.2 mg/kg) induced significant conditioned place preference. Exposure to acute or sub-chronic elevated platform stress potentiated the response of an ineffective dose of nicotine. Pre-conditioning intra-CA1 (0.5-4 µg/rat) or intra-medial prefrontal cortex (0.2-0.3 µg/rat) microinjection of mecamylamine (a non-selective nicotinic acetylcholine receptor antagonist) reversed acute stress-induced potentiation of nicotine reward as measured in the conditioned place preference paradigm. By contrast, pre-conditioning intra-basolateral amygdala microinjection of mecamylamine (4 µg/rat) potentiated the effects of acute stress on nicotine reward. Our findings also showed that intra-CA1 or intra-medial prefrontal cortex, but not intra-basolateral amygdala, microinjection of mecamylamine (4 µg/rat) prevented the effect of sub-chronic stress on nicotine reward. These findings suggest that exposure to elevated platform stress potentiates the rewarding effect of nicotine which may be associated with the involvement of nicotinic acetylcholine receptors. It seems that there is a different contribution of the basolateral amygdala, the medial prefrontal cortex or the CA1 nicotinic acetylcholine receptors in stress-induced potentiation of nicotine-induced conditioned place preference.

Ford, Brett Q; Mauss, Iris B; Gruber, June

2015-04-01

Although people who experience happiness tend to have better psychological health, people who value happiness to an extreme tend to have worse psychological health, including more depression. We propose that the extreme valuing of happiness may be a general risk factor for mood disturbances, both depressive and manic. To test this hypothesis, we examined the relationship between the extreme valuing of happiness and risk for, diagnosis of, and illness course for bipolar disorder (BD). Supporting our hypothesis, the extreme valuing of happiness was associated with a measure of increased risk for developing BD (Studies 1 and 2), increased likelihood of past diagnosis of BD (Studies 2 and 3), and worse prospective illness course in BD (Study 3), even when controlling for current mood symptoms (Studies 1-3). These findings indicate that the extreme valuing of happiness is associated with and even predicts BD. Taken together with previous evidence, these findings suggest that the extreme valuing of happiness is a general risk factor for mood disturbances. More broadly, what emotions people strive to feel may play a critical role in psychological health. (c) 2015 APA, all rights reserved).

Jun, W H; Jo, M J

2016-08-01

WHAT IS KNOWN ON THE SUBJECT?: Despite the increased interest in nursing students' happiness in South Korea, few studies have attempted to identify factors influencing their happiness. Therefore, nursing educators should consistently investigate the factors influencing happiness and develop strategies to improve happiness among Korean nursing students. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study confirmed that there were positive correlations between grateful disposition, social support and happiness. In addition, grateful disposition and support from intimate people were identified as predictors of happiness in Korean nursing students. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Development of intervention programmes to help nursing students increase grateful disposition and support from intimate people may be helpful for improving happiness. These programmes can include activity, such as writing a gratitude journal, and extracurricular programmes, such as mentoring programmes between seniors and juniors and/or professor and student. Introduction Happiness is very important in the training and development of nursing students as future nurses. However, nursing students experience a high level of stress and low level of happiness in South Korea. Aim This study aimed to investigate factors that affect happiness among nursing students in South Korea. Method Data were collected from a total of 241 nursing enrolled in two 4-year baccalaureate nursing programmes in South Korea, using a self-administrated questionnaire. To identify predictors of happiness, stepwise regression analysis was conducted. Results The results indicated that grateful disposition and support from intimate people significantly predict happiness among Korean nursing students. These two factors accounted for 38.0% of the variance in happiness. Discussion This study indicated grateful disposition and support from intimate people as factors promoting happiness in nursing students. The findings

The aim of this study was to measure happiness in a sample of Brazilian psychiatrists and correlate it with the defense styles used by them and sociodemographic data. This study was observational, cross-sectional, and analytical. Data were collected through self-administered questionnaires by Brazilian psychiatrists who participated in the XXXII Brazilian Congress of Psychiatry, 2014. In this sample of psychiatrists, happiness levels were high (scoring 5.69 of a total of 7), and mature defense styles prevailed, especially humor and anticipation. In a multivariate analysis, having children, good sleep quality, increased sexual interest, and use of defense styles such as humor, anticipation, and idealization all showed a positive relationship with happiness; on the other hand, using defense style such as acting out or annulment demonstrated a negative relationship with happiness. Despite the well-known professional burden that they bear, Brazilian psychiatrists surveyed presented, in general, high levels of subjective well-being and happiness.

Full Text Available It has been suggested that biological markers are associated with human happiness. We contribute to the empirical literature by examining the independent association between various aspects of biometric wellbeing measured in childhood and happiness in adulthood. Using Young Finns Study data (n = 1905 and nationally representative linked data we examine whether eight biomarkers measured in childhood (1980 are associated with happiness in adulthood (2001. Using linked data we account for a very rich set of confounders including age, sex, body size, family background, nutritional intake, physical activity, income, education and labour market experiences. We find that there is a negative relationship between triglycerides and subjective well-being but it is both gender- and age-specific and the relationship does not prevail using the later measurements (1983/1986 on triglycerides. In summary, we conclude that none of the eight biomarkers measured in childhood predict happiness robustly in adulthood.

Nicotine dependence and smoking frequency are critical factors for smoking cessation. The aims of this study are (1) to determine if nicotine dependence Fagerström Test for Nicotine Dependence (FTND) scores are associated with urinary levels of nicotine metabolites, (2) to assess the relationship of hydroxycotinine/cotinine ratio with FTND score and cigarettes smoked per day (CPD), and (3) to identify significant predictors of cigarettes per day among biomarker concentrations and individual FTND items. Urine samples and questionnaire data of 239 daily smokers were obtained. Nicotine, cotinine and hydroxycotinine urinary levels were determined by UPLC MS/MS.Multiple linear regression models were developed to explore the relationship between nicotine, cotinine, hydroxycotinine levels and separate FTND scores (for all six items). We found significant correlations between the different urinary biomarker concentrations, and the FTND score. The time before the first cigarette after waking (TTFC) was significantly associated with the nicotine, cotinine and hydroxycotinine concentrations. No association was found between the ratio of hydroxycotinine to cotinine and either the FTND or the CPD. A model including four FTND questions, sex, age, and the cotinine concentration, accounted for 45% of the variance of CPD. There are significant relationships between urinary levels of nicotine, cotinine, and hydroxycotinine and the FTND score. Especially the FTND question about TTFC is relevant for explaining the biomarker concentrations. CPD (below 15) was significantly explained by four FTND dependence items and urinary cotinine levels in a regression model. We investigated associations between urinary levels of nicotine, cotinine, and hydroxycotinine in daily smokers and the FTND scores for nicotine dependence. We did not find association between the hydroxycotinine/cotinine ratio and CPD. We developed a model that explains the cigarettes smoked daily (CPD) in a group of light

This paper reports on a 4-year longitudinal study of 60 elderly women. Data about their happiness and social activities were collected using the Affect Balance Scale and nine measures of socially relevant activities, including three measures of media use, three of interpersonal interaction, and three of activities in voluntary associations. Direct relationships between happiness and social activity among elderly people were found in analysis of these data. This finding was not spurious according to longitudinal data: activity increments were associated with happiness and decrements with unhappiness. Although these findings describe the over-all picture, changes in activities may be more important to happiness among the most elderly persons interviewed than others.

I argue that happiness is an exclusively categorical mental state. Daniel Haybron’s inclusion of dispositions into his emotional state theory rests of a confusion of constituents of happiness in the narrow psychological sense with objects of prudential concern, to which obviously belong “mood...... propensities” and other dispositional states. I further argue that while it is probably correct to require of a constituent of happiness that it must in some sense be “deep” and belong to, or directly impact on, a persons’ self, the importance of depth may be overrated by the emotional state theory, which also...

Clinical ethics and happiness.

Devettere, R J

Most contemporary accounts of clinical ethics do not explain why clinicians should be ethical. Those few that do attempt an explanation usually claim that clinicians should be ethical because ethical behavior provides an important good for the patient--better care. Both these approaches ignore the customary traditional reason for being ethical, namely, the good of the moral agent. This good was commonly called 'happiness'. The following article shows how the personal happiness of the moral agent provided a major reason for being ethical in the ancient philosophical and biblical traditions and how it continues to play a role in the more modern rights-based, Kantian and utilitarian theories. This history suggests that the personal happiness of the clinician, rightly understood, is a legitimate and important goal of clinical ethics.

Fetal and neonatal nicotine exposure in Wistar rats causes progressive pancreatic mitochondrial damage and beta cell dysfunction.

Directory of Open Access Journals (Sweden)

Full Text Available Nicotine replacement therapy (NRT is currently recommended as a safe smoking cessation aid for pregnant women. However, fetal and neonatal nicotine exposure in rats causes mitochondrial-mediated beta cell apoptosis at weaning, and adult-onset dysglycemia, which we hypothesize is related to progressive mitochondrial dysfunction in the pancreas. Therefore in this study we examined the effect of fetal and neonatal exposure to nicotine on pancreatic mitochondrial structure and function during postnatal development. Female Wistar rats were given saline (vehicle control or nicotine bitartrate (1 mg/kg/d via subcutaneous injection for 2 weeks prior to mating until weaning. At 3-4, 15 and 26 weeks of age, oral glucose tolerance tests were performed, and pancreas tissue was collected for electron microscopy, enzyme activity assays and islet isolation. Following nicotine exposure mitochondrial structural abnormalities were observed beginning at 3 weeks and worsened with advancing age. Importantly the appearance of these structural defects in nicotine-exposed animals preceded the onset of glucose intolerance. Nicotine exposure also resulted in significantly reduced pancreatic respiratory chain enzyme activity, degranulation of beta cells, elevated islet oxidative stress and impaired glucose-stimulated insulin secretion compared to saline controls at 26 weeks of age. Taken together, these data suggest that maternal nicotine use during pregnancy results in postnatal mitochondrial dysfunction that may explain, in part, the dysglycemia observed in the offspring from this animal model. These results clearly indicate that further investigation into the safety of NRT use during pregnancy is warranted.

Considering the extreme shortage of smoking cessation services in China, and the acceptability, feasibility and efficacy of mobile phone-based text message interventions for quitting smoking in other countries, here we propose a study of "the efficacy of mobile phone-based text message interventions ('Happy Quit') for smoking cessation in China". The primary objective of this proposed project is to assess whether a program of widely accessed mobile phone-based text message interventions ('Happy Quit') will be effective at helping people in China who smoke, to quit. Based on the efficacy of previous studies in smoking cessation, we hypothesize that 'Happy Quit' will be an effective, feasible and affordable smoking cessation program in China. In this single-blind, randomized trial, undertaken in China, about 2000 smokers willing to make a quit attempt will be randomly allocated, using an independent telephone randomization system that includes a minimization algorithm balancing for sex (male, female), age (19-34 or >34 years), educational level (≤ or >12 years), and Fagerstrom score for nicotine addiction (≤5, >5), to 'Happy Quit', comprising motivational messages and behavioral-change support, or to a control group that receives text messages unrelated to quitting. Messages will be developed to be suitable for Chinese. A pilot study will be conducted before the intervention to modify the library of messages and interventions. The primary outcome will be self-reported continuous smoking abstinence. A secondary outcome will be point prevalence of abstinence. Abstinence will be assessed at six time points (4, 8, 12, 16, 20 and 24 weeks post-intervention). A third outcome will be reductions in number of cigarettes smoked per day. The results will provide valuable insights into bridging the gap between need and services received for smoking cessation interventions and tobacco use prevention in China. It will also serve as mHealth model for extending the public

Schizophrenia is typically a chronic disorder and among the most severe forms of serious mental illnesses in terms of adverse impact on quality of life. Yet, there have been suggestions that some people with schizophrenia can experience an overall sense of happiness in their lives. We investigated happiness among 72 outpatients with non-remitted chronic schizophrenia with a mean duration of illness of 24.4 years, and 64 healthy comparison subjects (HCs). Despite continued treatment with antipsychotic medications, the individuals with schizophrenia manifested a mild to moderate level of psychopathology. People with schizophrenia reported lower mean levels of happiness than HCs, but there was substantial heterogeneity within the schizophrenia group. Level of happiness in persons with schizophrenia was significantly correlated with higher mental health-related quality of life, and several positive psychosocial factors (lower perceived stress, and higher levels of resilience, optimism, and personal mastery). However, level of happiness was not related to sociodemographic characteristics, duration of illness, severity of positive or negative symptoms, physical function, medical comorbidity, or cognitive functioning. Except for an absence of an association with resilience, the pattern of correlations of happiness with other variables seen among HCs was similar to that in individuals with schizophrenia. Although happiness may be harder to achieve in the context of a serious mental illness, it nonetheless appears to be a viable treatment goal in schizophrenia. Psychotherapies targeting positive coping factors such as resilience, optimism, and personal mastery warrant further investigation. Copyright © 2014. Published by Elsevier B.V.

Towards a functional neuroanatomy of pleasure and happiness

Kringelbach, Morten L.; Berridge, Kent C.

2009-01-01

The pursuit of happiness is a preoccupation for many people. Yet only the pursuit can be promised, not happiness itself. Can science help? We focus on the most tractable ingredient, hedonia or positive affect. A step toward happiness might be gained by improving the pleasures and positive moods in daily life. The neuroscience of pleasure and reward provides relevant insights, and we discuss how specific hedonic mechanisms might relate to happiness or the lack thereof. Although the neuroscience of happiness is still in its infancy, further advances might be made through mapping overlap between brain networks of hedonic pleasure with others, such as the brain's default network, potentially involved in the other happiness ingredient, eudemonia or life meaning and engagement.

2014-12-01

Full Text Available The concept of happiness has been discussed long time ago by economists. Recently, it became the most related and important thing to be studied because of its impact in societies. Discussion about happiness basically interprets within two separate views. First, happiness related with economic variable, for instance, how money can create happiness. Second happiness is discussed within the context of religion. However, the discussion did not combine both contexts, economic variable and religion, to interpret happiness. Therefore, it is important to highlight the concept of happiness in a different way such as in this article. Different cultures will have their own perspective on the determination of happiness. From just “individual perspective” of happiness, they then formed an ism through involvement of a big society from the same culture. Some isms such as hedonism and materialism are synonyms in characterizing the concept of happiness in this modern world. At the same time, the isms are actually working with the economic and non-economic indicators as elements to strengthen the ism itself. On the other hand, the concept of happiness from the perspective of religion will also be a part of discussion in this article. Therefore, this article will reveal that the meaning of happiness is different in terms of religion and ism. So, to carry out both ism and religion simultaneously in shaping a more intrinsic value of happiness is not an easy task. Furthermore, religion is always associated with spiritual value that makes it hard for some people to practice religion and their isms at the same time. Thus, this article will propose that the right interpretation of isms based on their faith in religion can contribute to the concept of genuine happiness.

Conceptions of Happiness and Unhappiness among Italian Psychology Undergraduates.

Sotgiu, Igor

2016-01-01

The present study aims at investigating the conceptions of happiness and unhappiness in a sample of Italian psychology undergraduates. Participants completed a questionnaire asking them to report the most important things that made them feel happy (happiness components) and those ones that made them feel unhappy (unhappiness components). Different measures of overall happiness and overall unhappiness were also obtained by asking respondents to assess to what extent each reported happiness and unhappiness component was present in their life, and by inviting them to provide a global judgment about their happiness and unhappiness. Results indicated that participants did not conceptualize happiness and unhappiness as perfect antonyms. Indeed, both investigated concepts encompassed a similar set of semantic components; however, the perceived salience of some of them - assessed in terms of frequency of citation and average ranking - significantly varied between happiness and unhappiness. With regard to the measurement of overall happiness and unhappiness, on average, respondents considered themselves as moderately happy and only slightly unhappy. However, a judgmental asymmetry was found when comparing global and specific evaluations of unhappiness. Theoretical and empirical implications of the study are discussed.

This quantitative study assessed whether presentation of preferred items and activities during multiple periods of the day (and over multiple days) increased indices of happiness (over time/sustained) in individuals with PMD. A multiple baseline design across participants was utilized to measure changes in indices of happiness of the participants. Participants were recruited from an adult day activity program specializing in providing assistance to individuals with disabilities. For Mary, baseline indices of happiness were 26.67% of intervals, increasing 6.76% during intervention to 33.43%. For Caleb, baseline indices of happiness were 20.84% of intervals, increasing 6.34% during intervention to 27.18%. For Mark, baseline indices of happiness were 40.00% of intervals, increasing 12.75% during intervention to 52.75%. Overall interobserver agreement was 82.8%, with interobserver agreement observations occurring during 63.04% of the observations. The results of the investigation demonstrated that presenting preferred items and activities increased the indices of happiness compared to baseline rates of indices of happiness. Results may have been more robust if the participants were assessed for overall responsiveness patterns prior to the initiation of measurement of indices of happiness. Copyright © 2015 Elsevier Ltd.

To review the available literature evaluating electronic cigarette (e-cigarette) nicotine clinical pharmacology in order to understand the potential impact of e-cigarettes on individual users, nicotine dependence and public health. Literature searches were conducted between 1 October 2012 and 30 September 2013 using key terms in five electronic databases. Studies were included in the review if they were in English and publicly available; non-clinical studies, conference abstracts and studies exclusively measuring nicotine content in e-cigarette cartridges were excluded from the review. Nicotine yields from automated smoking machines suggest that e-cigarettes deliver less nicotine per puff than traditional cigarettes, and clinical studies indicate that e-cigarettes deliver only modest nicotine concentrations to the inexperienced e-cigarette user. However, current e-cigarette smokers are able to achieve systemic nicotine and/or cotinine concentrations similar to those produced from traditional cigarettes. Therefore, user experience is critically important for nicotine exposure, and may contribute to the products' ability to support and maintain nicotine dependence. Knowledge about e-cigarette nicotine pharmacology remains limited. Because a user's e-cigarette experience may significantly impact nicotine delivery, future nicotine pharmacokinetic and pharmacodynamic studies should be conducted in experienced users to accurately assess the products' impact on public health.

To assess the level of happiness and satisfaction in the life and medical practice of dermatologists in Mexico. A descriptive study (online survey) was conducted focused on practicing dermatologists in our country. Questions included demographic characteristics, the Pemberton happiness index (with local validation) and questions that assessed the degree of personal satisfaction. Descriptive statistics were used to obtain the central tendency and dispersion. Measures of central tendency and dispersion were performed; to compare categorical variables, contingency tables for chi-square test were used and when comparing quantitative variables with normal distribution, Student’s t t-test was used. 219 surveys were included, 72.6% female and 27.4% male, with an average age of 45.6 and an average of 16 years of medical practice. Most of them (64.8%) graduate from Mexico City; 93% were very satisfied with the specialty and 98.6% of them would choose the same once again, the most important reason is to encompass medical and surgical areas. The level of happiness by using the Pemberton scale was “high” (mode: 9.11; standard deviation: 1.73). This first study in Latin America on this subject in dermatologists showed high levels of satisfaction and happiness in both professional and personal areas. Copyright: © 2018 SecretarÍa de Salud

Decreased sensitivity to nicotine-induced seizures as a consequence of nicotine pretreatment in long-sleep and short-sleep mice.

Science.gov (United States)

de Fiebre, C M; Collins, A C

1988-01-01

Male and female long-sleep (LS) and short-sleep (SS) mice were pretreated with a subseizure-producing dose of nicotine (2.0 mg/kg) 7.5, 15 and 30 minutes prior to challenge with seizure-producing doses of this drug. Nicotine pretreated animals were less susceptible to nicotine-induced seizures than were saline pretreated animals. The latency to seizure following nicotine challenge was greater in nicotine pretreated animals than in saline controls. Nicotine pretreated LS mice show a greater decrease in nicotine-induced seizure susceptibility than do nicotine pretreated SS mice. This decrease in seizure susceptibility is consistent with induction of nicotinic receptor desensitization via nicotine pretreatment. It is hypothesized that LS and SS mice might differ in sensitivity to nicotine in part because they differ in baseline levels of desensitized versus functional nicotinic receptors.

2016-11-01

Tobacco smoking is the leading cause of preventable death in the United States. Nicotine is the principal psychoactive ingredient in tobacco that causes addiction. The structures governing nicotine addiction, including those underlying withdrawal, are still being explored. Nicotine withdrawal is characterized by negative affective and cognitive symptoms that enhance relapse susceptibility, and suppressed dopaminergic transmission from ventral tegmental area (VTA) to target structures underlies behavioral symptoms of nicotine withdrawal. Agonist and partial agonist therapies help 1 in 4 treatment-seeking smokers at one-year post-cessation, and new targets are needed to more effectively aid smokers attempting to quit. Hypothalamic orexin/hypocretin neurons send excitatory projections to dopamine (DA)-producing neurons of VTA and modulate mesoaccumbal DA release. The effects of nicotinic receptor blockade, which is commonly used to precipitate withdrawal, on orexin neurons remain poorly investigated and present an attractive target for intervention. The present study sought to investigate the effects of nicotinic receptor blockade on hypothalamic orexin neurons using mecamylamine to precipitate withdrawal in rats. Separate groups of rats were treated with either chronic nicotine or saline for 7-days at which point effects of mecamylamine or saline on somatic signs and anxiety-like behavior were assessed. Finally, tissue from rats was harvested for immunofluorescent analysis of Fos within orexin neurons. Results demonstrate that nicotinic receptor blockade leads to reduced orexin cell activity, as indicated by lowered Fos-immunoreactivity, and suggest that this underlying cellular activity may be associated with symptoms of nicotine withdrawal as effects were most prominently observed in rats given chronic nicotine. We conclude from this study that orexin transmission becomes suppressed in rats upon nicotinic receptor blockade, and that behavioral symptoms associated

Chronic electronic (e) cigarette users have increased resting cardiac sympathetic nerve activity and increased susceptibility to oxidative stress. The purpose of the present study is to determine the role of nicotine versus non-nicotine constituents in e-cigarette emissions in causing these pathologies in otherwise healthy humans. Thirty-three healthy volunteers who were not current e-cigarette or tobacco cigarette smokers were studied. On different days, each participant used an e-cigarette with nicotine, an e-cigarette without nicotine, or a sham control. Cardiac sympathetic nerve activity was determined by heart rate variability, and susceptibility to oxidative stress was determined by plasma paraoxonase activity. Following exposure to the e-cigarette with nicotine, but not to the e-cigarette without nicotine or the sham control, there was a significant and marked shift in cardiac sympathovagal balance towards sympathetic predominance. The decrease in high-frequency component and the increases in the low-frequency component and the low-frequency to high-frequency ratio were significantly greater following exposure to the e-cigarette with nicotine compared with exposure to the e-cigarette without nicotine or to sham control. Oxidative stress, as estimated by plasma paraoxonase, did not increase following any of the 3 exposures. The acute sympathomimetic effect of e-cigarettes is attributable to the inhaled nicotine, not to non-nicotine constituents in e-cigarette aerosol, recapitulating the same heart rate variability pattern associated with increased cardiac risk in multiple populations with and without known cardiac disease. Evidence of oxidative stress, as estimated by plasma paraoxonase activity, was not uncovered following acute e-cigarette exposure. © 2017 The Authors.

Current and future directions in culture and happiness research.

Science.gov (United States)

Oishi, Shigehiro; Gilbert, Elizabeth A

2016-04-01

Once believed to be universal, a growing body of research shows that both the conception and predictors of happiness vary cross-culturally. First, the meaning and importance of happiness varies both across time and between nations. Americans, for instance, tend to define happiness in terms of pleasure or enjoyment and view happiness as universally positive, whereas East Asian and Middle Eastern cultures may highlight the transient and socially disruptive nature of happiness and be ambivalent about whether it is good. Second, predictors of happiness vary between cultures. Recent work highlights new mediators (e.g., relational mobility), individual predictors (e.g., person-culture fit), societal factors (e.g., good governance and wealth), within-culture variations (e.g., at the state or city level), and interventions (e.g., practicing gratitude) that differ cross-culturally or help explain cultural differences in happiness. Though many questions remain, this review highlights how these recent advances broaden and revise our understanding of culture and happiness. Copyright © 2015 Elsevier Ltd. All rights reserved.

2016-01-01

This study explores the determinants (demographic, personal, behavioural, and social) by which happy and unhappy people differ. The primary sample from which the participants were chosen was a representative sample of Croatian citizens (N = 4000). On the basis of the distribution of overall happiness the sample of the highest (the happy group) and the lowest 10 % of participants (the unhappy group) were selected. The happy group (N = 400) represented the upper end of the happiness distribution, while the unhappy group (N = 400) represented the lower end of the distribution. The questionnaire included demographic characteristics (age, gender, income, and education), ratings of subjective health status, satisfaction with specific personal and national domains (IWI-International Wellbeing Index), trust in people, and trust in institutions. Frequency of various leisure activities, and involvement in the community life were also reported. The differences in examined variables were analysed between the two groups. Results showed that the happy individuals were younger, with higher income, and with higher education than unhappy ones. After controlling for age, income, and education level, the happy people were found to be more satisfied with personal and national wellbeing domains, of better subjective health status, reported higher trust in people and institutions, and were more engaged in leisure activities and community life than the unhappy ones.

Counterbalanced, repeated measures with four conditions: i) low nicotine (6 mg/mL)/fixed power; ii) low nicotine/adjustable power; iii) high nicotine (18 mg/mL)/fixed power; iv) high nicotine/adjustable power. London and the South East, England. Twenty experienced e-cigarette users (recruited between September 2016 and February 2017) vaped ad libitum using an eVic Supreme™ with a 'Nautilus Aspire' tank over four weeks (one week per condition). Puffing patterns (daily puff number [PN], puff duration [PD], inter-puff interval [IPI]), mL of e-liquid consumed, changes to power (where permitted), and subjective effects (urge to vape, nicotine withdrawal symptoms) were measured in each condition. Nicotine intake was measured via salivary cotinine. 3-hydroxypropylmercapturic acid (3-HPMA), a metabolite of the toxicant acrolein, and formate, a metabolite of the carcinogen formaldehyde, were measured in urine. There was a significant nicotine concentration x power interaction for PD (p<0.01). PD was longer with low nicotine/fixed power compared with i) high nicotine/fixed power (p< 0.001 and ii) low nicotine/adjustable power (p< 0.01). PN and liquid consumed were higher in the low versus high nicotine condition (main effect of nicotine, p<0.05). Urge to vape and withdrawal symptoms were lower, and nicotine intake was higher, in the high nicotine condition (main effects of nicotine: p<0.01). Whilst acrolein levels did not differ, there was a significant nicotine x power interaction for formaldehyde (p<0.05). Use of a lower nicotine concentration e-liquid may be associated with compensatory behaviour (e.g., higher number and duration of puffs) and increases

Happiness and memory: affective significance of endowment and contrast.

2009-10-01

Three studies (two conducted in Israel and one in the United States) examined associations between self-rated dispositional happiness and tendencies to treat memories of positive and negative events as sources of enhanced or attenuated happiness through the use of "endowment" and "contrast." Although participants generally endorsed items describing happiness-enhancing tendencies more than happiness-diminishing ones, self-reported happiness was associated with greater endorsement of "positive endowment" items and less endorsement of "negative endowment" items, and also with less endorsement of items that involved contrasting the present with happier times in the past. Only in the American sample, however, was happiness associated with greater endorsement of items that involved contrasting the present with less happy times in the past. These data suggest that relatively unhappy people show somewhat conflicting memorial tendencies vis-à-vis happiness, whereas very happy people show simpler, and less conflicting, tendencies. These findings augment the existing literatures on the affective consequences of memory, which have been concerned more with mood than with temperament and/or have dealt only with a subset of the endowment and contrast tendencies explored in the present work.

Predictors of the nicotine reinforcement threshold, compensation, and elasticity of demand in a rodent model of nicotine reduction policy.

The FDA is considering reducing the nicotine content in tobacco products as a population-based strategy to reduce tobacco addiction. Research is needed to determine the threshold level of nicotine needed to maintain smoking and the extent of compensatory smoking that could occur during nicotine reduction. Sources of variability in these measures across sub-populations also need to be identified so that policies can take into account the risks and benefits of nicotine reduction in vulnerable populations. The present study examined these issues in a rodent nicotine self-administration model of nicotine reduction policy to characterize individual differences in nicotine reinforcement thresholds, degree of compensation, and elasticity of demand during progressive reduction of the unit nicotine dose. The ability of individual differences in baseline nicotine intake and nicotine pharmacokinetics to predict responses to dose reduction was also examined. Considerable variability in the reinforcement threshold, compensation, and elasticity of demand was evident. High baseline nicotine intake was not correlated with the reinforcement threshold, but predicted less compensation and less elastic demand. Higher nicotine clearance predicted low reinforcement thresholds, greater compensation, and less elastic demand. Less elastic demand also predicted lower reinforcement thresholds. These findings suggest that baseline nicotine intake, nicotine clearance, and the essential value of nicotine (i.e. elasticity of demand) moderate the effects of progressive nicotine reduction in rats and warrant further study in humans. They also suggest that smokers with fast nicotine metabolism may be more vulnerable to the risks of nicotine reduction. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Sources of variability in these measures across sub-populations also need to be identified so that policies can take into account the risks and benefits of nicotine reduction in vulnerable populations. Methods The present study examined these issues in a rodent nicotine self- administration model of nicotine reduction policy to characterize individual differences in nicotine reinforcement thresholds, degree of compensation, and elasticity of demand during progressive reduction of the unit nicotine dose. The ability of individual differences in baseline nicotine intake and nicotine pharmacokinetics to predict responses to dose reduction was also examined. Results Considerable variability in the reinforcement threshold, compensation, and elasticity of demand was evident. High baseline nicotine intake was not correlated with the reinforcement threshold, but predicted less compensation and less elastic demand. Higher nicotine clearance predicted low reinforcement thresholds, greater compensation, and less elastic demand. Less elastic demand also predicted lower reinforcement thresholds. Conclusions These findings suggest that baseline nicotine intake, nicotine clearance, and the essential value of nicotine (i.e. elasticity of demand) moderate the effects of progressive nicotine reduction in rats and warrant further study in humans. They also suggest that smokers with fast nicotine metabolism may be more vulnerable to the risks of nicotine reduction. PMID:25891231

Full Text Available Consumers are described by economists as rational people when making a decision and when interacting with different types of framing problems. Theories explaining rational "consumer's rational behaviour" , assume that emotions can be controlled and even ignored so people be able to behave in a rational manner. An important issue was to establish the rational economic report between resources and needs and finding ways to optimize it. Rational consumer behaviour is considered to be one that ensures maximum consumer satisfaction with maximum efficiency at minimum cost. Each user asks himself at one point, if happiness is found in material goods and services. Economists would like that the consumers believe that in their attempt to explain buying behaviour. However, it is a matter of debate if psychological records tend to state otherwise. It is suggested that people buy goods and services hoping that they will substitute the factors that make them truly happy . It is debatable whether consumption is detrimental to human happiness and if the link between consumption and happiness extends to all buying experiences.

Full Text Available Abstract Background The behavioural impact of pharmacogenomics is untested; informing smokers of genetic test results for responsiveness to smoking cessation medication may increase adherence to this medication. The objective of this trial is to estimate the impact upon adherence to nicotine replacement therapy (NRT of informing smokers that their oral dose of NRT has been tailored to a DNA analysis. Hypotheses to be tested are as follows: IAdherence to NRT is greater among smokers informed that their oral dose of NRT is tailored to an analysis of DNA (genotype, compared to one tailored to nicotine dependence questionnaire score (phenotype. II Amongst smokers who fail to quit at six months, motivation to make another quit attempt is lower when informed that their oral dose of NRT was tailored to genotype rather than phenotype. Methods/Design An open label, parallel groups randomised trial in which 630 adult smokers (smoking 10 or more cigarettes daily using National Health Service (NHS stop smoking services in primary care are randomly allocated to one of two groups: i. NRT oral dose tailored by DNA analysis (OPRM1 gene (genotype, or ii. NRT oral dose tailored by nicotine dependence questionnaire score (phenotype The primary outcome is proportion of prescribed NRT consumed in the first 28 days following an initial quit attempt, with the secondary outcome being motivation to make another quit attempt, amongst smokers not abstinent at six months. Other outcomes include adherence to NRT in the first seven days and biochemically validated smoking abstinence at six months. The primary outcome will be collected on 630 smokers allowing sufficient power to detect a 7.5% difference in mean proportion of NRT consumed using a two-tailed test at the 5% level of significance between groups. The proportion of all NRT consumed in the first four weeks of quitting will be compared between arms using an independent samples t-test and by estimating the 95

Climate is an important input to many human activities. Climate affects heating and cooling requirements, health, clothing and nutritional needs as well as recreational activities. As such, it is to be expected that individuals will have a preference for particular types of climate. This paper analyses a panel of 67 countries attempting to explain differences in self-reported levels of happiness by reference to, amongst other things, temperature and precipitation. Various indices are used for each of these variables, including means, extremes and the number of hot, cold, wet and dry months. Using a panel-corrected least squares approach, the paper demonstrates that, even when controlling for a range of other factors, climate variables have a highly significant effect on country-wide self-reported levels of happiness. On the basis of these results, it is determined that differential patterns of anthropogenically induced climate change might alter dramatically the distribution of happiness between nations, with some countries moving towards a preferred climate and others moving further away. We find that high-latitude countries included in our dataset might benefit from temperature changes. Countries already characterized by very high summer temperatures would most likely suffer losses from climate change.

Global tobacco deaths are high and rising. Tobacco use is primarily driven by nicotine addiction. Overall tobacco control policy is relatively well agreed upon but a long term nicotine policy has been less well considered and requires further debate. Reaching consensus is important because a nicotine policy is integral to the target of reducing tobacco caused disease, and the contentious issues need to be resolved before the necessary political changes can be sought. A long term and comprehensive nicotine policy is proposed here. It envisages both reducing the attractiveness and addictiveness of existing tobacco based nicotine delivery systems as well as providing alternative sources of acceptable clean nicotine as competition for tobacco. Clean nicotine is defined as nicotine free enough of tobacco toxicants to pass regulatory approval. A three phase policy is proposed. The initial phase requires regulatory capture of cigarette and smoke constituents liberalising the market for clean nicotine; regulating all nicotine sources from the same agency; and research into nicotine absorption and the role of tobacco additives in this process. The second phase anticipates clean nicotine overtaking tobacco as the primary source of the drug (facilitated by use of regulatory and taxation measures); simplification of tobacco products by limitation of additives which make tobacco attractive and easier to smoke (but tobacco would still be able to provide a satisfying dose of nicotine). The third phase includes a progressive reduction in the nicotine content of cigarettes, with clean nicotine freely available to take the place of tobacco as society's main nicotine source.

Happiness is a major factor that influences people’s perceptions and behavior. Two-stage least squares regression was applied to investigate the effect of happiness on the psychological integration of migrant workers in China. The data for a total of 1625 individuals were obtained from the 2014 China Labor-force Dynamics Survey (CLDS). This study describes happiness from three main aspects: happiness, life satisfaction, and economic satisfaction. The psychological integration includes two dimensions of settlement willingness, and trust level; these have gone through dimension-reduced processing by using the weighted average method. The empirical evidence shows, first, that happiness has a significantly positive effect on the psychological integration of migrant workers and second, that the sense of life satisfaction in particular plays a more significant role. The acceleration of the social and political integration in migrant workers will enhance their psychological integration. Additionally, social, cultural and economic integration is found to influence migrant workers’ psychological integration by promoting happiness. Happiness between different generations of migrant workers was found to have a noticeably positive impact on their psychological integration; however, the happiness of the younger migrant workers was more perceivable than that of the other generations. Preferential policies should therefore be provided to improve the happiness of migrant workers.

Full Text Available The emergence of the epidemic of nicotine addiction in India and other nations is a global public health tragedy of untoward proportions. Smoking or chewing tobacco can seriously affect general, as well as oral health. Smoking-caused disease is a consequence of exposure to toxins in tobacco smoke and addiction to nicotine is the proximate cause of these diseases. This article focuses on nicotine as a determinant of addiction to tobacco and the pharmacologic effects of nicotine that sustain cigarette smoking. The pharmacologic reasons for nicotine use are an enhancement of mood, either directly or through relief of withdrawal symptoms and augmentation of mental or physical functions. Tobacco cessation is necessary to reduce morbidity and mortality related to tobacco use. Strategies for tobacco cessation involves 5A's and 5R's approach and pharmacotherapy. Dental professionals play an important role in helping patients to quit tobacco at the community and national levels, to promote tobacco prevention and control nicotine addiction. Dentists are in a unique position to educate and motivate patients concerning the hazards of tobacco to their oral and systemic health, and to provide intervention programs as a part of routine patient care.

Surveillance of smokeless tobacco nicotine, pH, moisture, and unprotonated nicotine content.

Smokeless tobacco is a complex chemical mixture, including not only the components of the tobacco leaf but also chemicals added during the manufacturing process. Smokeless tobacco contains the addictive chemical nicotine and more than 20 cancer-causing chemicals, including the potent tobacco-specific nitrosamines. The National Toxicology Program of the National Institutes of Health has concluded that oral use of smokeless tobacco is a human carcinogen. Therefore, smokeless tobacco is not a safe alternative to cigarettes. In fact, smokeless tobacco use begins primarily during early adolescence and can lead to nicotine dependence and increased risk of becoming a cigarette smoker. Under the Comprehensive Smokeless Tobacco Health Education Act of 1986 (15 U.S.C. 4401 et seq., Pub. L. 99-252), tobacco manufacturers report annually to the Centers for Disease Control and Prevention (CDC) on the total nicotine, unprotonated nicotine, pH, and moisture content of their smokeless tobacco products. This information is considered "trade secret," or confidential, in accordance with 5 U.S.C. 552(b)(4) and 18 U.S.C. 1905 and cannot be released to the public. In an effort to provide consumers and researchers with information on the nicotine content of smokeless tobacco, CDC arranged for the analysis of popular brands of smokeless tobacco. The results of this CDC study show that pH is a primary factor in the amount of nicotine that is in the most readily absorbable, unprotonated form. Furthermore, this study found that the brands of moist snuff smokeless tobacco with the largest amount of unprotonated nicotine also are the most frequently sold brands.

Potential contribution of aromatase inhibition to the effects of nicotine and related compounds on the brain

Full Text Available Cigarette smoking continues to be a major public health problem, and while smoking rates in men have shown some decrease over the last few decades, smoking rates among girls and young women are increasing. Practically all of the important aspects of cigarette smoking are sexually dimorphic. Women become addicted more easily than men, while finding it harder to quit. Nicotine replacement appears to be less effective in women. This may be linked to the observation that women are more sensitive than men to non-nicotine cues or ingredients in cigarettes. The reasons for these sex differences are mostly unknown. Several lines of evidence suggest that many of the reported sex differences related to cigarette smoking may stem from the inhibitory effects of nicotine and other tobacco alkaloids on estrogen synthesis via the enzyme aromatase (cyp19a gene product. Aromatase is the last enzyme in estrogen biosynthesis, catalyzing the conversion of androgens to estrogens. This review provides a summary of experimental evidence supporting brain aromatase as a potential mediator and/or modulator of nicotine actions in the brain, contributing to sex differences in smoking behavior. Additional research on the interaction between tobacco smoke, nicotine and aromatase may help devise new, sex specific methods for prevention and treatment of smoking addiction.

This research examines the relationship between individuals' levels of life satisfaction and their associative networks of happiness. Study 1 measured European Americans' degree of false memory of happiness using the Deese-Roediger-McDermott paradigm. Scores on the Satisfaction With Life Scale predicted the likelihood of false memory of happiness but not of other lure words such as sleep . In Study 2, European American participants completed an association-judgment task in which they judged the extent to which happiness and each of 15 positive emotion terms were associated with each other. Consistent with Study 1's findings, chronically satisfied individuals exhibited stronger associations between happiness and other positive emotion terms than did unsatisfied individuals. However, Koreans and Asian Americans did not exhibit such a pattern regarding their chronic level of life satisfaction (Study 3). In combination, results suggest that there are important individual and cultural differences in the cognitive structure and associative network of happiness.

Smoking abstinence impairs executive function, which may promote continued smoking behavior and relapse. The differential influence of nicotine and non-nicotine (i.e. sensory, motor) smoking factors and related neural substrates is not known. In a fully factorial, within-subjects design, 33 smokers underwent fMRI scanning following 24 hours of wearing a nicotine or placebo patch while smoking very low nicotine content cigarettes or remaining abstinent from smoking. During scanning, blood oxygenation level-dependent (BOLD) signal was acquired while participants performed a verbal N-back task. Following 24-hour placebo (versus nicotine) administration, accuracy on the N-back task was significantly worse and task-related BOLD signal lower in dorsomedial frontal cortex. These effects were observed irrespective of smoking. Our data provide novel evidence that abstinence-induced deficits in working memory and changes in underlying brain function are due in large part to abstinence from nicotine compared with non-nicotine factors. This work has implications both for designing interventions that target abstinence-induced cognitive deficits and for nicotine-reduction policy. © 2015 Society for the Study of Addiction.

The study examined the effect of peripheral (intragastric) ICI-204,448, an agonist of gastric κ-opioid receptors, on the psychostimulating and anxiolytic effects of caffeine in nicotinedependent rats at the stage of nicotine withdrawal. In these rats, the effects of caffeine (10 mg/kg) were perverted. In nicotine-dependent rats, caffeine produced an anxiolytic effect accompanied by pronounced stimulation of motor activity, in contrast to anxiogenic effect induced by caffeine in intact rats without nicotine dependence. During nicotine withdrawal, nicotine-dependent rats demonstrated enhanced sensitivity to nicotine. Intragastric administration of κ-opioid receptor agonist ICI-204,448 normalized the effect of caffeine in nicotinedependent rats. We have previously demonstrated that activation of peripheral κ-opioid receptors inhibited central κ-opioid activity and eliminated manifestations of nicotine withdrawal syndrome in nicotine-dependent rats, e.g. metabolism activation, stimulation of motor activity, and enhancement of food consumption. In its turn, inhibition of central κ-opioid structures activates the brain adenosine system, which can attenuate the caffeine-induced effects in nicotine-dependent rats.

Black-Right-Pointing-Pointer Nicotine receptor antagonists attenuate HSC proliferation. Black-Right-Pointing-Pointer Nicotinic receptor antagonists may have utility as novel anti-fibrotic agents. -- Abstract: Background and aims: Cigarette smoke (CS) may cause liver fibrosis but possible involved mechanisms are unclear. Among the many chemicals in CS is nicotine - which affects cells through nicotinic acetylcholine receptors (nAChR). We studied the effects of nicotine, and involved pathways, on human primary hepatic stellate cells (hHSCs), the principal fibrogenic cells in the liver. We then determined possible disease relevance by assaying nAChR in liver samples from human non-alcoholic steatohepatitis (NASH). Methods: hHSC were isolated from healthy human livers and nAChR expression analyzed - RT-PCR and Western blotting. Nicotine induction of hHSC proliferation, upregulation of collagen1-{alpha}2 and the pro-fibrogenic cytokine transforming growth factor beta 1 (TGF-{beta}1) was determined along with involved intracellular signaling pathways. nAChR mRNA expression was finally analyzed in whole liver biopsies obtained from patients diagnosed with non-alcoholic steatohepatitis (NASH). Results: hHSCs express muscle type ({alpha}1, {beta}1, delta and epsilon) and neuronal type ({alpha}3, {alpha}6, {alpha}7, {beta}2 and {beta}4) nAChR subunits at the mRNA level. Among these subunits, {alpha}3, {alpha}7, {beta}1 and {epsilon} were predominantly expressed as confirmed by Western blotting. Nicotine induced hHSC proliferation was attenuated by mecamylamine (p < 0.05). Additionally, collagen1-{alpha}2 and TGF-{beta}1 mRNA expression were significantly upregulated by nicotine and inhibited by

Personality traits have been directly associated with happiness. One consistent finding is a strong link between extraversion and happiness: extraverts are happier than introverts. Although happy introverts exist, it is currently unclear under what conditions they can achieve happiness. The present study analyzes, generally, how the quality of social relationships and emotion regulation ability influence happiness and, specifically, how these factors can lead introverts to be happy. In the present study, 1,006 participants aged 18–80 (42% males) completed measures of extraversion, neuroticism, quality of social relationships, emotion regulation ability, and happiness. We found that extraverts had significantly higher happiness, quality of social relationships and emotion regulation ability scores than introverts. In addition, people with high quality social relationships or high emotion regulation ability were happier. Serial mediation analyses indicated that greater levels of extraversion were associated with greater happiness, with small effect size, via two indirect mechanisms: (a) higher quality of social relationships, and (b) higher quality of social relationships followed serially by higher emotion regulation ability. We also found a moderating effect due to the three-way interaction of extraversion, quality of social relationships, and emotion regulation ability: introverts were happier when they had high scores for these two variables, though the effect size was small. These results suggest that the quality of social relationships and emotion regulation ability are relevant to our understanding of complex associations between extraversion and happiness.

How sadness and happiness influence ethnic stereotyping

2012-01-01

Full Text Available Incidental affective states tend to influence stereotyping in counterintuitive way: experimentally induced happiness leads to more stereotyping while experimentally induced sadness leads to less stereotyping. It was therefore predicted that happy subjects would a. would make more stereotype-consistent errors in memory task; b. attribute more stereotypical features to a specific ethnic group, and c. be less sensitive to ethnic discrimination in comparison to sad subjects. In a sample of 90 high school students from Belgrade, Serbia, differently valenced affects were successfully induced using 'autobiographic recollection' procedure. Experiment 1 showed that happy and sad subjects did not differ in the number of stereotype consistent errors in memory task. In experiment 2, however, happy subjects in comparison to sad subjects attributed more stereotypic traits to a non-stereotypical exemplar of a national category and expected him to behave more stereotypically in the future. Additionally, in thought listing task, happy subjects recorded more irrelevant and less story-focused thoughts in comparison to sad subjects. Finally, in Experiment 3 (N=66 sad subjects demonstrated more sensitivity to ethnic discrimination in comparison to happy subjects. These findings are discussed in terms of the impact of emotional experience on social information-processing strategies.

The pharmacokinetics of nicotine, the pharmacologically active alkaloid in tobacco responsible for addiction, are well characterized in humans. We developed a physiologically based pharmacokinetic/pharmacodynamic model of nicotine pharmacokinetics, brain dosimetry and brain nicotinic acetylcholine receptor (nAChRs) occupancy. A Bayesian framework was applied to optimize model parameters against multiple human data sets. The resulting model was consistent with both calibration and test data sets, but in general underestimated variability. A pharmacodynamic model relating nicotine levels to increases in heart rate as a proxy for the pharmacological effects of nicotine accurately described the nicotine related changes in heart rate and the development and decay of tolerance to nicotine. The PBPK model was utilized to quantitatively capture the combined impact of variation in physiological and metabolic parameters, nicotine availability and smoking compensation on the change in number of cigarettes smoked and toxicant exposure in a population of 10,000 people presented with a reduced toxicant (50%), reduced nicotine (50%) cigarette Across the population, toxicant exposure is reduced in some but not all smokers. Reductions are not in proportion to reductions in toxicant yields, largely due to partial compensation in response to reduced nicotine yields. This framework can be used as a key element of a dosimetry-driven risk assessment strategy for cigarette smoke constituents.

Electronic nicotine delivery systems (ENDS, often called e-cigarettes) are nicotine delivery devices that heat nicotine into vapour that is inhaled, a process called 'vaping'. Use eclipsed nicotine-replacement therapy (NRT) in 2014 but ENDS role in smoking cessation remains controversial. Safety has not been proven and there have been reports to US poison centres regarding potential ENDS-related nicotine toxicity. A further concern is use of ENDS to vape recreational drugs, but there is limited data to substantiate this. The aim of this study was to report on ENDS use to vape recreational drugs in patrons of a South London nightclub where high prevalence of recreational drug use has previously been shown. A convenience sample of 101 participants was surveyed in March 2015 as part of a larger survey on drug use. Individuals were asked if they used ENDS to vape nicotine and/or other substances (and if so which substances). Ninety (89.1 %) of respondents were male with median age of 28 years (IQR 23-34). Eighty (79.2 %) currently smoked cigarettes; 20 (19.8 %) currently used ENDS for nicotine. Six (5.9 %) reported using ENDS to take other substances: 2 for 'liquid cannabis' and 4 did not elaborate on the substance(s) used. Of these 6, 3 were using ENDS to vape nicotine and 3 had never used them for nicotine. 5.9 % of individuals in this sample reported using ENDS to vape substances other than nicotine. Further work is required in larger populations to determine how common this is, evaluate which agents are being vaped and to inform appropriate public education.

This study utilized observational and self-report data from 57 happily married couples to explore assumptions regarding marital happiness. Suggesting that happily married couples are not a homogeneous group, cluster analyses revealed the existence of three types of couples based on their observed behaviors in a problem-solving task: (1) mutually engaged couples (characterized by both spouses' higher negative and positive problem-solving); (2) mutually supportive couples (characterized by both spouses' higher positivity and support); and (3) wife compensation couples (characterized by high wife positivity). Although couples in all three clusters were equally happy with and committed to their marriages, these clusters were differentially associated with spouses' evaluations of their marriage. Spouses in the mutually supportive cluster reported greater intimacy and maintenance and less conflict and ambivalence, although this was more consistently the case in comparison to the wife compensation cluster, as opposed to the mutually engaged cluster. The implications of these typologies are discussed as they pertain to efforts on the part of both practitioners to promote marital happiness and repair marital relations when couples are faced with difficulties. © FPI, Inc.

remains unclear. The use of e-cigarettes as a quit aid was not associated with reductions in conventional smoking, consistent with most other quit aids in this sample except for nicotine replacement therapy, which was only effective for the most dependent smokers. Notably, these findings highlight the necessity of accounting for smokers' nicotine dependence levels when examining tobacco use patterns. © The Author 2017.

The purpose of this analysis is to examine and clarify the concept of nurses' happiness (NH), understand the different uses of the concept, explore the conditions that foster it, and consider the consequences of NH, including the phenomena that emerge as a result of NH occurrence. The author utilizes Walker and Avant's eight-stage concept analysis. Computer and manual searches were conducted of articles in the English language addressing NH from 1990 to present. EBSCO and PubMed are the electronic databases used to access literature for this paper. For both databases, the researcher has examined this new term by splitting the term nurses' happiness into its two root words, namely nurses and happiness. An inductive analysis of articles produced descriptive themes. Definitions of happiness and NH are analyzed. Antecedents, attributes, and consequences of NH are described. Model, borderline, contrary, and related cases for NH are also identified. This concept analysis helps in the understanding of the definition of NH, the attributes that contribute to the occurrence of NH in clinical practice, as well as the consequences of NH, and how it should be measured from a nursing perspective.

Aversive and smoking-related stimuli are related to smoking urges and relapse and can be potent distractors of selective attention. It has been suggested that the beneficial effect of nicotine replacement therapy may be mediated partly by the ability of nicotine to reduce distraction by such stimuli and thereby to facilitate attention to task-relevant stimuli. The present study tested the hypothesis that nicotine reduces distraction by aversive and smoking-related stimuli as indexed by the parietal P3b brain response to a task-relevant target digit. We assessed the effect of nicotine on distraction by emotionally negative, positive, neutral, and smoking-related pictures immediately preceding target digits during a rapid visual information processing task in 16 smokers in a double-blind, counterbalanced, within-subjects design. The study included two experimental sessions. After overnight smoking deprivation (12+ hr), active nicotine patches were applied to participants during one of the sessions and placebo patches were applied during the other session. Nicotine enhanced P3b responses associated with target digits immediately subsequent to negative emotional pictures bilaterally and subsequent to smoking-related pictures only in the right hemisphere. No effects of nicotine were observed for P3bs subsequent to positive and neutral distractor pictures. Another measure of attention, contingent negative variation amplitude in anticipation of the target digits also was increased by nicotine, especially in the left hemisphere and at posterior sites. Together, these findings suggest that nicotine reduces the distraction by emotionally negative and smoking-related stimuli and promotes attention to task-related stimuli by modulating somewhat lateralized and task-specific neural networks.

Low Nicotine Content Descriptors Reduce Perceived Health Risks and Positive Cigarette Ratings in Participants Using Very Low Nicotine Content Cigarettes.

Understanding how smokers perceive reduced nicotine content cigarettes will be important if the FDA and global regulatory agencies implement reduced nicotine product standards for cigarettes. Prior research has shown that some smokers incorrectly believe "light" cigarettes are less harmful than regular cigarettes. Similar misunderstandings of health risk could also apply to reduced nicotine cigarettes. To date, most studies of reduced nicotine cigarettes have blinded subjects to the nicotine content. Therefore, little is known about how smokers experience reduced nicotine content cigarettes when they are aware of the reduced content, and how use may be impacted. The present study was a within-subjects experiment with 68 adult daily smokers who smoked two identical very low nicotine content Quest 3 (0.05 mg nicotine yield) cigarettes. Subjects were told that one cigarette contained "average" nicotine content, and the other contained "very low" nicotine content. After smoking each cigarette, subjects completed subjective measures about their smoking experience. Subjects rated the "very low" nicotine cigarette as less harmful to their health overall compared to the "average" nicotine cigarette; this effect held true for specific smoking-related diseases. Additionally, they rated the "very low" nicotine cigarette as having less desirable subjective effects than the "average" nicotine cigarette and predicted having greater interest in quitting smoking in the future if only the "very low" nicotine cigarette was available. Explicit knowledge of very low nicotine content changes smokers' perceptions of very low nicotine content cigarettes, resulting in reduced predicted harm, subjective ratings and predicted future use. Before a reduced nicotine product standard for cigarettes can be implemented, it is important to understand how product information impacts how smokers think about and experience very low nicotine content cigarettes. Prior research has shown that smokers

E-cigarettes are popular among youth, but little is known about the nicotine concentrations of e-liquids used by adolescents. In Spring, 2014, we conducted cross-sectional surveys in four Connecticut high schools and two middle schools. Among past-30-day e-cigarette users (n=513, 45% female, mean age 15.9 [SD=1.4]), we examined what nicotine concentration adolescents typically used in their e-cigarettes (range 0-30mg/mL and "I don't know"). We first examined whether age, sex, smoking status, e-cigarette use frequency, and/or e-cigarette acquisition source were associated with using nicotine-free e-liquid, nicotine e-liquid, or not knowing the e-liquid nicotine concentration. Among nicotine users (n=185), we then examined whether the aforementioned variables were associated with using higher nicotine concentrations. Adolescents reported using nicotine-free e-liquid (28.5%), nicotine e-liquid (37.4%), or not knowing their e-liquid nicotine concentration (34.1%). Nicotine users comprised more smokers and heavier e-cigarette users compared to nicotine-free e-liquid users and those who did not know their nicotine concentration. Nicotine users also comprised more males and were more likely to purchase e-cigarettes online or from tobacco shops compared to those who did not know their nicotine concentration. Among nicotine users, cigarette smoking, male sex, and purchasing e-cigarettes from tobacco shops predicted using higher nicotine concentrations. Adolescents reported using e-liquids with variable nicotine concentrations. Smokers, males, and those who purchased their own e-cigarettes reported using the highest nicotine levels. Of concern, many adolescents were unaware of the nicotine concentration in their e-liquid, raising concerns about inadvertent nicotine exposure among youth. Copyright © 2016 Elsevier Ireland Ltd.

2014-01-01

Perception of subtle facial expressions is essential for social functioning; yet it is unclear if human perceptual sensitivities differ in detecting varying types of facial emotions. Evidence diverges as to whether salient negative versus positive emotions (such as sadness versus happiness) are preferentially processed. Here, we measured perceptual thresholds for the detection of four types of emotion in faces--happiness, fear, anger, and sadness--using psychophysical methods. We also evaluated the association of the perceptual performances with facial morphological changes between neutral and respective emotion types. Human observers were highly sensitive to happiness compared with the other emotional expressions. Further, this heightened perceptual sensitivity to happy expressions can be attributed largely to the emotion-induced morphological change of a particular facial feature (end-lip raise).

Nicotine reward and affective nicotine withdrawal signs are attenuated in calcium/calmodulin-dependent protein kinase IV knockout mice.

Directory of Open Access Journals (Sweden)

Kia J Jackson

Full Text Available The influx of Ca(2+ through calcium-permeable nicotinic acetylcholine receptors (nAChRs leads to activation of various downstream processes that may be relevant to nicotine-mediated behaviors. The calcium activated protein, calcium/calmodulin-dependent protein kinase IV (CaMKIV phosphorylates the downstream transcription factor cyclic AMP response element binding protein (CREB, which mediates nicotine responses; however the role of CaMKIV in nicotine dependence is unknown. Given the proposed role of CaMKIV in CREB activation, we hypothesized that CaMKIV might be a crucial molecular component in the development of nicotine dependence. Using male CaMKIV genetically modified mice, we found that nicotine reward is attenuated in CaMKIV knockout (-/- mice, but cocaine reward is enhanced in these mice. CaMKIV protein levels were also increased in the nucleus accumbens of C57Bl/6 mice after nicotine reward. In a nicotine withdrawal assessment, anxiety-related behavior, but not somatic signs or the hyperalgesia response are attenuated in CaMKIV -/- mice. To complement our animal studies, we also conducted a human genetic association analysis and found that variants in the CaMKIV gene are associated with a protective effect against nicotine dependence. Taken together, our results support an important role for CaMKIV in nicotine reward, and suggest that CaMKIV has opposing roles in nicotine and cocaine reward. Further, CaMKIV mediates affective, but not physical nicotine withdrawal signs, and has a protective effect against nicotine dependence in human genetic association studies. These findings further indicate the importance of calcium-dependent mechanisms in mediating behaviors associated with drugs of abuse.

Neonatal Nicotine Exposure Increases Excitatory Synaptic Transmission and Attenuates Nicotine-stimulated GABA release in the Adult Rat Hippocampus

Developmental exposure to nicotine has been linked to long-lasting changes in synaptic transmission which may contribute to behavioral abnormalities seen in offspring of women who smoke during pregnancy. Here, we examined the long-lasting effects of developmental nicotine exposure on glutamatergic and GABAergic neurotransmission, and on acute nicotine-induced glutamate and GABA release in the adult hippocampus, a structure important in cognitive and emotional behaviors. We utilized a chronic neonatal nicotine treatment model to administer nicotine (6 mg/kg/day) to rat pups from postnatal day (P) 1–7, a period that falls developmentally into the third human trimester. Using whole-cell voltage clamp recordings from CA1 pyramidal neurons in hippocampal slices, we measured excitatory and inhibitory postsynaptic currents in neonatally control- and nicotine-treated young adult males. Neonatal nicotine exposure significantly increased AMPA receptor-mediated spontaneous and evoked excitatory signaling, with no change in glutamate release probability in adults. Conversely, there was no increase in spontaneous GABAergic neurotransmission in nicotine-males. Chronic neonatal nicotine treatment had no effect on acute nicotine-stimulated glutamate release in adults, but acute nicotine-stimulated GABA release was significantly attenuated. Thus, neonatal nicotine exposure results in a persistent net increase in excitation and a concurrent loss of nicotinic acetylcholine receptor (nAChR)-mediated regulation of presynaptic GABA but not glutamate release, which would exacerbate excitation following endogenous or exogenous nAChR activation. Our data underscore an important role for nAChRs in hippocampal excitatory synapse development, and suggest selective long-term changes at specific presynaptic nAChRs which together could explain some of the behavioral abnormalities associated with maternal smoking.

The pursuit of happiness is enshrined in the founding document of our nation as a fundamental and inalienable right. Yet nowhere is the method of this pursuit clearly defined. What, exactly, does it mean to be happy, and how can such happiness be sustained over the long term? Can happiness be accurately gauged or measured? How does the paradoxical relationship between happiness and pleasure shape our quest to lead the good life? And what does modern science have to tell us about this universal yet elusive pursuit?

Internet discussion forums provide new, albeit less used data sources for exploring personal experiences of illness and treatment strategies. To gain an understanding of how discussion forum participants value nicotine replacement therapy (NRT) in smoking cessation (SC). Finnish national Internet-based discussion forum, STUMPPI, supporting SC and consisting of ten free discussion areas, each with a different focus. The analysis was based on STUMPPI forum participants' postings (n = 24 481) in five discussion areas during January 2007-January 2012. Inductive content analysis of the postings concerning NRT use or comparing NRT to other SC methods. Three major themes related to NRT in SC emerged from the discussions. These were as follows: (I) distrust and negative attitude towards NRT; (II) neutral acceptance of NRT as a useful SC method; and (III) trust on the crucial role of NRT and other SC medicines. The negative attitude was related to following perceptions: NRT use maintains tobacco dependence, fear of NRT dependence or experience of not gaining help from NRT use. NRT was perceived to be useful particularly in the initiation of SC attempts and in dealing with physiological dependence. The most highlighted factors of successful quitting were quitters' own psychological empowerment and peer support from the discussion community. The majority of STUMPPI forum participants had low or balanced expectations towards the role of NRT in SC. More research from the smokers' and quitters' perspective is needed to assess the real value of NRT compared to other methods in SC. © 2014 John Wiley & Sons Ltd.

Neuronal nicotinic acetylcholine receptors: Common molecular substrates of nicotine and alcohol dependence

Directory of Open Access Journals (Sweden)

Linzy M. Hendrickson

2013-04-01

Full Text Available Alcohol and nicotine are often co-abused. As many as 80-95% of alcoholics are also smokers, suggesting that ethanol and nicotine, the primary addictive component of tobacco smoke, may functionally interact in the central nervous system and/or share a common mechanism of action. While nicotine initiates dependence by binding to and activating neuronal nicotinic acetylcholine receptors (nAChRs, ligand-gated cation channels normally activated by endogenous acetylcholine (ACh, ethanol is much less specific with the ability to modulate multiple gene products including those encoding voltage-gated ion channels, and excitatory/inhibitory neurotransmitter receptors. However, emerging data indicate that ethanol interacts with nAChRs, both directly and indirectly, in the mesocorticolimbic dopaminergic (DAergic reward circuitry to affect brain reward systems. Like nicotine, ethanol activates DAergic neurons of the ventral tegmental area (VTA which project to the nucleus accumbens (NAc. Blockade of VTA nAChRs reduces ethanol-mediated activation of DAergic neurons, NAc DA release, consumption, and operant responding for ethanol in rodents. Thus, ethanol may increase ACh release into the VTA driving activation of DAergic neurons through nAChRs. In addition, ethanol potentiates distinct nAChR subtype responses to ACh and nicotine in vitro and in DAergic neurons. The smoking cessation therapeutic and nAChR partial agonist, varenicline, reduces alcohol consumption in heavy drinking smokers and rodent models of alcohol consumption. Finally, single nucleotide polymorphisms in nAChR subunit genes are associated with alcohol dependence phenotypes and smoking behaviors in human populations. Together, results from preclinical, clinical, and genetic studies indicate that nAChRs may have an inherent role in the abusive properties of ethanol, as well as in nicotine and alcohol co-dependence.

The authors have studied DNA adduction with 14 C-labelled nicotine and nicotine-derived nitrosamine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), by accelerator mass spectrometry (AMS) in mouse liver at doses equivalent to low-level exposure of humans. The dose ranges of nicotine and NNK administered were from 0.4 μg to 4.0 x 10 2 μg·kg -1 , and from 0.1 μg to 2.0 x 10 4 μg·kg -1 , respectively. In the exposure of mice to either nicotine or NNK, the number of DNA adducts increased linearly with increasing dose. The detection limit of DNA adducts was 1 adduct per 10 11 nucleotide molecules. This limit is 1-4 orders of magnitude lower than that of other techniques used for quantification of DNA adducts. The results of the animal experiments enabled us to speculate that nicotine is a potential carcinogen. According to the procedure for 14 C-labelled-NNK synthesis, the authors discuss the ultimate chemical speciation of NNK bound to DNA. From the animal tests the authors derived a directly perceivable relation between tobacco consumption and DNA adduction as the carcinogenic risk assessment

Pathogenesis of Abdominal Aortic Aneurysms: Role of Nicotine and Nicotinic Acetylcholine Receptors

Directory of Open Access Journals (Sweden)

Zong-Zhuang Li

2012-01-01

Full Text Available Inflammation, proteolysis, smooth muscle cell apoptosis, and angiogenesis have been implicated in the pathogenesis of abdominal aortic aneurysms (AAAs, although the well-defined initiating mechanism is not fully understood. Matrix metalloproteinases (MMPs such as MMP-2 and -9 and other proteinases degrading elastin and extracellular matrix are the critical pathogenesis of AAAs. Among the risk factors of AAAs, cigarette smoking is an irrefutable one. Cigarette smoke is practically involved in various aspects of the AAA pathogenesis. Nicotine, a major alkaloid in tobacco leaves and a primary component in cigarette smoke, can stimulate the MMPs expression by vascular SMCs, endothelial cells, and inflammatory cells in vascular wall and induce angiogenesis in the aneurysmal tissues. However, for the inflammatory and apoptotic processes in the pathogenesis of AAAs, nicotine seems to be moving in just the opposite direction. Additionally, the effects of nicotine are probably dose dependent or associated with the exposure duration and may be partly exerted by its receptors—nicotinic acetylcholine receptors (nAChRs. In this paper, we will mainly discuss the pathogenesis of AAAs involving inflammation, proteolysis, smooth muscle cell apoptosis and angiogenesis, and the roles of nicotine and nAChRs.

Progressive taxation, income inequality, and happiness.

Oishi, Shigehiro; Kushlev, Kostadin; Schimmack, Ulrich

2018-01-01

Income inequality has become one of the more widely debated social issues today. The current article explores the role of progressive taxation in income inequality and happiness. Using historical data in the United States from 1962 to 2014, we found that income inequality was substantially smaller in years when the income tax was more progressive (i.e., a higher tax rate for higher income brackets), even when controlling for variables like stock market performance and unemployment rate. Time lag analyses further showed that higher progressive taxation predicted increasingly lower income inequality up to 5 years later. Data from the General Social Survey (1972-2014; N = 59,599) with U.S. residents (hereafter referred to as "Americans") showed that during years with higher progressive taxation rates, less wealthy Americans-those in the lowest 40% of the income distribution-tended to be happier, whereas the richest 20% were not significantly less happy. Mediational analyses confirmed that the association of progressive taxation with the happiness of less wealthy Americans can be explained by lower income inequality in years with higher progressive taxation. A separate sample of Americans polled online (N = 373) correctly predicted the positive association between progressive taxation and the happiness of poorer Americans but incorrectly expected a strong negative association between progressive taxation and the happiness of richer Americans.

2017-11-01

Psychotic-like experiences (PLEs) have been associated with a variety of adverse outcomes but how they affect happiness in individuals with PLE is unknown. Thus, the aim of the study was to assess the association between PLEs and happiness, and the factors that may influence this association. Nationally representative data from the 2007 Adult Psychiatric Morbidity Survey including adults aged ≥ 16 years was analyzed. The Psychosis Screening Questionnaire was used to assess past 12-month PLE. Individuals who endorsed at least one of the following were considered to have any PLE: thought control, paranoia, strange experiences, auditory hallucinations. Happiness (3-point scale) was assessed with a validated question with higher scores indicating lower levels of happiness. The association between PLE and happiness was assessed by multivariable ordinal logistic regression. Mediation analysis was also performed. Among the 7363 individuals included in the analysis, the prevalence of any PLE increased with decreasing levels of happiness [very happy (2.3%), fairly happy (5.4%), not too happy (14.9%)]. This was also shown in the multivariable analysis adjusted for sociodemographic factors and stressful life events (from very happy to not too happy: OR = 2.41; 95%CI = 1.86-3.12). Mediation analysis showed that anxiety disorders explained the largest proportion of the association (38.8%) followed by depressive episode (28.5%), insomnia (21.9%), disability (16.5%), pain (12.5%), social support (10.0%), and physical health conditions (6.0%). The cross-sectional design limits causal inference. Interventions to identify and address conditions that may have a negative impact on happiness in individuals with PLE may be important to improve their well-being. Copyright © 2017 Elsevier B.V.

To estimate (1) the immediate impact; (2) the cumulative impact; and (3) the duration of impact of Scottish tobacco control TV mass media campaigns (MMCs) on smoking cessation activity, as measured by calls to Smokeline and the volume of prescribed nicotine replacement therapy (NRT). Multivariate time-series analysis using secondary data on population level measures of exposure to TV MMCs broadcast and smoking cessation activity between 2003 and 2012. Population of Scotland. Adult television viewer ratings (TVRs) as a measure of exposure to Scottish mass media campaigns in the adult population; monthly calls to NHS Smokeline; and the monthly volume of prescribed NRT as measured by gross ingredient costs (GIC). Tobacco control TVRs were associated with an increase in calls to Smokeline but not an increase in the volume of prescribed NRT. A 1 standard deviation (SD) increase of 194 tobacco control TVRs led to an immediate and significant increase of 385.9 [95% confidence interval (CI) = 171.0, 600.7] calls to Smokeline (unadjusted model) within 1 month. When adjusted for seasonality the impact was reduced, but the increase in calls remained significant (226.3 calls, 95% CI = 37.3, 415.3). The cumulative impact on Smokeline calls remained significant for 6 months after broadcast in the unadjusted model and 18 months in the adjusted model. However, an increase in tobacco control TVRs of 194 failed to have a significant impact on the GIC of prescribed NRT in either the unadjusted (£1361.4, 95% CI = -£9138.0, £11860.9) or adjusted (£6297.1, 95% CI = -£2587.8, £15182.1) models. Tobacco control television mass media campaigns broadcast in Scotland between 2003 and 2012 were effective in triggering calls to Smokeline, but did not increase significantly the use of prescribed nicotine replacement therapy by adult smokers. The impact on calls to Smokeline occurred immediately within 1 month of broadcast and was sustained for at least 6 months. © 2017 The

2015-10-01

Full Text Available Background: Happiness as one of the main positive health indicators has drawn more attention in recent years among policy makers and health system managers. There are few studies performed to measure happiness in population-based settings in Iran. In response to this need, our study tends to assess Iranians subjective happiness in Tehran, Capital city of Iran.Materials and Methods: Present study was conducted in Tehran, Capital of Iran, with more than 7 Million populations in January 2013, using a two-step approach. In first step c conceptual framework of Iranians’ happiness was developed. In the second phase of study, a survey recruiting 700 participants was conducted. Stratified cluster sampling method was employed. Participants were recruited from all the 22 municipal divisions of Tehran as strata, proportional to the population size and its gender and age distribution. Happiness was measure by a 40-item questionnaire with scores ranged among 40 to 200.Results: Conceptual framework of Iranians’ happiness based on reviewed documents and consensus building process was the product of first step. At second step, from a pool of 700 persons, 696 (97% agreed to participate and filled out the questionnaire completely.  The mean of happiness score was 143.9 (95% confidence interval, 142.5 to 145.4. The results show that the happiness score of jobless people (135.1, 95%CI: 128.1-142.0 and widowed singles (126.6, 95%CI: 113.0-140.2 were significantly lower than other corresponding groups. There was no significant association between gender, age group, educational level as determinants and happiness.Conclusion: Happiness level of Tehranians is somewhat higher than the moderate level. This finding is consistent with findings of other conducted studies in country. However, it is not consistent with some of international reports of happiness, For instance, Happy Planet Index. Due to inadequate information, it is necessary to conduct more research to

Objectives: Little is known about whether the feeling of happiness follows the age-related decline in physical and mental functioning. The objective of this study was to analyze differences with age in physical and mental functions and in the feeling of happiness among Danes aged 45 years and older......-reported mobility, a cognitive composite score, and a depression symptomatology score including a question about happiness were assessed. T-score metric was used to compare across domains and age groups.

Habenular expression of rare missense variants of the β4 nicotinic receptor subunit alters nicotine consumption

Directory of Open Access Journals (Sweden)

Marta A Ślimak

2014-01-01

Full Text Available The CHRNA5-CHRNA3-CHRNB4 gene cluster, encoding the α5, α3 and β4 nicotinic acetylcholine receptor (nAChR subunits, has been linked to nicotine dependence. The habenulo-interpeduncular (Hb-IPN tract is particularly enriched in α3β4 nAChRs. We recently showed that modulation of these receptors in the medial habenula (MHb in mice altered nicotine consumption. Given that β4 is rate-limiting for receptor activity and that single nucleotide polymorphisms (SNPs in CHRNB4 have been linked to altered risk of nicotine dependence in humans, we were interested in determining the contribution of allelic variants of β4 to nicotine receptor activity in the MHb. We screened for missense SNPs with allele frequencies > 0.0005 and introduced the corresponding substitutions in Chrnb4. Fourteen variants were analyzed by co-expression with α3. We found that β4A90I and β4T374I variants, previously shown to associate with reduced risk of smoking, and an additional variant β4D447Y, significantly increased nicotine-evoked current amplitudes, while β4R348C, the mutation most frequently encountered in sporadic amyotrophic lateral sclerosis (sALS, showed reduced nicotine currents. We employed lentiviruses to express β4 or β4 variants in the MHb. Immunoprecipitation studies confirmed that β4 lentiviral-mediated expression leads to specific upregulation of α3β4 but not β2 nAChRs in the Mhb. Mice injected with the β4-containing virus showed pronounced aversion to nicotine as previously observed in transgenic Tabac mice overexpressing Chrnb4 at endogenous sites including the MHb. Habenular expression of the β4 gain-of-function allele T374I also resulted in strong aversion, while transduction with the β4 loss-of function allele R348C failed to induce nicotine aversion. Altogether, these data confirm the critical role of habenular β4 in nicotine consumption, and identify specific SNPs in CHRNB4 that modify nicotine-elicited currents and alter nicotine

Felicidad y constitucionalismo = Happiness and constitutionalism

Full Text Available La importancia de la felicidad, y su oportuna vinculación con la justicia, ha sido puesta de manifiesto desde el pensamiento filosófico clásico griego. Sin embargo, recientemente puede apreciarse claramente el creciente protagonismo y la inusitada actualidad que ha alcanzado el tema de la búsqueda de la felicidad en el discurso político, lo que obliga a meditar sobre ella como principio rector o directriz orientadora del Estado Social, y a saber detectar su presencia —explícita o implícita— en los textos constitucionales. Sólo en una sociedad democrática, y desde el desarrollo efectivo de los derechos fundamentales y de los derechos sociales, particularmente, será posible alcanzar una vida digna, y a partir de ahí, obtener el basamento adecuado para la búsqueda de la felicidad. La felicidad, pues, no es sólo un objetivo individual, es también un asunto público que ha de venir propiciado desde el propio Estado, en cuanto que desde los poderes públicos pueden establecerse las bases adecuadas para su consecución. En la CE de 1978 podemos encontrar preceptos para entender implícitamente incluida la felicidad como directriz orientadora del Estado en sus políticas públicas, y poder sostener así la presencia de una teoría eudemonista en nuestro Estado Social. Percibir la existencia de una notable preocupación por la felicidad de los ciudadanos en el desarrollo de las políticas públicas actuales supone, en cualquier caso, un afortunado retorno hacia el ámbito de lo humano, una nueva oportunidad para preocuparnos por el ser persona. Happiness has been linked to justice since ancient times, particularly since the beginning of Greek Classical Thought. However, nowadays the importance of happiness can surprisingly be found again in political speech, which makes us think about it, and obviously it is worth doing. Happiness could be considered as a main principle of the Social State. This idea obliges us to look carefully into

The pursuit of happiness: time, money, and social connection.

Science.gov (United States)

Mogilner, Cassie

2010-09-01

Does thinking about time, rather than money, influence how effectively individuals pursue personal happiness? Laboratory and field experiments revealed that implicitly activating the construct of time motivates individuals to spend more time with friends and family and less time working-behaviors that are associated with greater happiness. In contrast, implicitly activating money motivates individuals to work more and socialize less, which (although productive) does not increase happiness. Implications for the relative roles of time versus money in the pursuit of happiness are discussed.

Looking for boomerang effects: a pre-post experimental study of the effects of exposure of youth to television advertising for nicotine replacement therapy and Zyban.

Durkin, Sarah; Wakefield, Melanie; Spittal, Matt

2006-12-01

In the context of concerns about unintended "boomerang" influences of advertising, this study aimed to examine effects of nicotine replacement therapy (NRT) and Zyban advertising on youth perceptions of the ease of quitting, health risks of smoking and future intentions to smoke. 718 youth aged 14-16years were randomly allocated to view four television ads promoting either: NRT; Zyban; non-pharmaceutical cessation services (telephone Quitline); or non-cessation messages on sun protection. Questionnaire measures were administered before and after viewing ads. There were no effects of advertising exposure on perceived health effects of smoking or intentions to smoke. Compared with the sun protection ads, but not the Quitline ads, those exposed to NRT ads reported stronger perceptions about the ease of quitting, but non-susceptible non-smokers primarily drove this difference. This study suggests that exposure to NRT and Zyban advertising in an experimental context does not reliably influence youth smoking-related beliefs, especially those vulnerable to becoming regular smokers.

Happiness increases distraction by auditory deviant stimuli.

Science.gov (United States)

Pacheco-Unguetti, Antonia Pilar; Parmentier, Fabrice B R

2016-08-01

Rare and unexpected changes (deviants) in an otherwise repeated stream of task-irrelevant auditory distractors (standards) capture attention and impair behavioural performance in an ongoing visual task. Recent evidence indicates that this effect is increased by sadness in a task involving neutral stimuli. We tested the hypothesis that such effect may not be limited to negative emotions but reflect a general depletion of attentional resources by examining whether a positive emotion (happiness) would increase deviance distraction too. Prior to performing an auditory-visual oddball task, happiness or a neutral mood was induced in participants by means of the exposure to music and the recollection of an autobiographical event. Results from the oddball task showed significantly larger deviance distraction following the induction of happiness. Interestingly, the small amount of distraction typically observed on the standard trial following a deviant trial (post-deviance distraction) was not increased by happiness. We speculate that happiness might interfere with the disengagement of attention from the deviant sound back towards the target stimulus (through the depletion of cognitive resources and/or mind wandering) but help subsequent cognitive control to recover from distraction. © 2015 The British Psychological Society.

Central estrogenic pathways protect against the depressant action of acute nicotine on reflex tachycardia in female rats

International Nuclear Information System (INIS)

El-Mas, Mahmoud M.; Fouda, Mohamed A.; El-gowilly, Sahar M.; Saad, Evan I.

2012-01-01

We have previously shown that acute exposure of male rats to nicotine preferentially attenuates baroreceptor-mediated control of reflex tachycardia in contrast to no effect on reflex bradycardia. Here, we investigated whether female rats are as sensitive as their male counterparts to the baroreflex depressant effect of nicotine and whether this interaction is modulated by estrogen. Baroreflex curves relating reflex chronotropic responses evoked by i.v. doses (1–16 μg/kg) of phenylephrine (PE) or sodium nitroprusside (SNP), were constructed in conscious freely moving proestrus, ovariectomized (OVX), and estrogen (50 μg/kg/day s.c., 5 days)-replaced OVX (OVXE 2 ) rats. Slopes of the curves were taken as a measure of baroreflex sensitivity (BRS PE and BRS SNP ). Nicotine (100 μg/kg i.v.) reduced BRS SNP in OVX rats but not in proestrus or OVXE 2 rats. The attenuation of reflex tachycardia by nicotine was also evident in diestrus rats, which exhibited plasma estrogen levels similar to those of OVX rats. BRS PE was not affected by nicotine in all rat preparations. Experiments were then extended to determine whether central estrogenic receptors modulate the nicotine–BRS SNP interaction. Intracisteral (i.c.) treatment of OVX rats with estrogen sulfate (0.2 μg/rat) abolished the BRS SNP attenuating effect of i.v. nicotine. This protective effect of estrogen disappeared when OVX rats were pretreated with i.c. ICI 182,780 (50 μg/rat, selective estrogen receptor antagonist). Together, these findings suggest that central neural pools of estrogen receptors underlie the protection offered by E 2 against nicotine-induced baroreceptor dysfunction in female rats. -- Highlights: ► Estrogen protects against the depressant effect of nicotine on reflex tachycardia. ► The baroreflex response and estrogen status affect the nicotine–BRS interaction. ► The protection offered by estrogen is mediated via central estrogen receptors.

Global use of electronic nicotine delivery systems (ENDS; also called electronic cigarettes, e-cigarettes) has increased dramatically in recent years. However, due to the limited safety studies and growing concerns on the potential toxicity from long term use of ENDS, many national and international governments have employed regulatory measures to curtail its use. One of the most significant challenges regulators of ENDS encounter is the lack of quality standards to assess ENDS, e-liquid (solution used with ENDS which contain nicotine--a highly toxic and addictive substance), and amount of nicotine delivery to aerosol during ENDS use. Aims of the study were to (1) measure and compare nicotine concentration in e-liquids to values reported by manufacturers on packaging labels; (2) assess the precision of nicotine delivery from tank during aerosol formation. Methods: Nine popular Polish e-liquids (based on the market share data from October 2014) were purchased for the study. The labelled nicotine concentration for the selected e-liquids ranged between 11-25 mg/mL. All e-liquids were aerosolized in the laboratory using a smoking simulation machine (Palaczbot). Each e-liquid was aerosolized in a series of 6 consecutive bouts. A single bout consisted of 15 puffs with the following puff topography: 65 mL puff volume, 2.8 sec. puff duration, and 19 sec. interpuff interval. A total of 90 puffs were generated from each e-liquid. Nicotine content in the e-liquids and the aerosol generated were determined by gas chromatography with thermionic sensitive detection (GC-TSD). For seven of nine analyzed e-liquids, the difference between measured and manufacturer labeled nicotine concentration was less than 10%. Nicotine dose in aerosol per bout ranged between 0.77-1.49 mg (equivalent to one-half the nicotine a smoker inhales from a single combustible cigarette). Our analysis showed the high consistency between the labeled and measured nicotine concentration for popular on the

Avoidance of the negative affective (emotional) symptoms of nicotine withdrawal (e.g., anhedonia, anxiety) contributes to tobacco addiction. Establishing the minimal nicotine exposure conditions required to demonstrate negative affective withdrawal signs in animals, as well as understanding moderators of these conditions, could inform tobacco addiction-related research, treatment, and policy. The goal of this study was to determine the minimal duration of continuous nicotine infusion required to demonstrate nicotine withdrawal in rats as measured by elevations in intracranial self-stimulation (ICSS) thresholds (anhedonia-like behavior). Administration of the nicotinic acetylcholine receptor antagonist mecamylamine (3.0 mg/kg, s.c.) on alternate test days throughout the course of a 2-week continuous nicotine infusion (3.2 mg/kg/day via osmotic minipump) elicited elevations in ICSS thresholds beginning on the second day of infusion. Magnitude of antagonist-precipitated withdrawal did not change with further nicotine exposure and mecamylamine injections, and was similar to that observed in a positive control group receiving mecamylamine following a 14-day nicotine infusion. Expression of a significant withdrawal effect was delayed in nicotine-infused rats receiving mecamylamine on all test days rather than on alternate test days. In a separate study, rats exhibited a transient increase in ICSS thresholds following cessation of a 2-day continuous nicotine infusion (3.2 mg/kg/day). Magnitude of this spontaneous withdrawal effect was similar to that observed in rats receiving a 9-day nicotine infusion. Our findings demonstrate that rats exhibit antagonist-precipitated and spontaneous nicotine withdrawal following a 2-day continuous nicotine infusion, at least under the experimental conditions studied here. Magnitude of these effects were similar to those observed in traditional models involving more prolonged nicotine exposure. Further development of these models

Pure nicotine impairs macrophage killing of Mycobacterium tuberculosis (MTB), but it is not known whether the nicotine component in cigarette smoke (CS) plays a role. Moreover, the mechanisms by which nicotine impairs macrophage immunity against MTB have not been explored. To neutralize the effects of nicotine in CS extract, we used a competitive inhibitor to the nicotinic acetylcholine receptor (nAChR)-mecamylamine-as well as macrophages derived from mice with genetic disruption of specific subunits of nAChR. We also determined whether nicotine impaired macrophage autophagy and whether nicotine-exposed T regulatory cells (Tregs) could subvert macrophage anti-MTB immunity. Mecamylamine reduced the CS extract increase in MTB burden by 43%. CS extract increase in MTB was also significantly attenuated in macrophages from mice with genetic disruption of either the α7, β2, or β4 subunit of nAChR. Nicotine inhibited autophagosome formation in MTB-infected THP-1 cells and primary murine alveolar macrophages, as well as increased the intracellular MTB burden. Nicotine increased migration of THP-1 cells, consistent with the increased number of macrophages found in the lungs of smokers. Nicotine induced Tregs to produce transforming growth factor-β. Naive mouse macrophages co-cultured with nicotine-exposed Tregs had significantly greater numbers of viable MTB recovered with increased IL-10 production and urea production, but no difference in secreted nitric oxide as compared with macrophages cocultured with unexposed Tregs. We conclude that nicotine in CS plays an important role in subverting macrophage control of MTB infection.

2008-01-01

An analytical method of measuring nicotine in house dust was optimized and associations among three secondhand smoking exposure markers were evaluated, i.e., nicotine concentrations of both house dust and indoor air, and the self-reported number of cigarettes smoked daily in a household. We obtained seven house dust samples from self-reported nonsmoking homes and 30 samples from smoking homes along with the information on indoor air nicotine concentrations and the number of cigarettes smoked daily from an asthma cohort study conducted by the Johns Hopkins Center for Childhood Asthma in the Urban Environment. House dust nicotine was analyzed by isotope dilution gas chromatography-mass spectrometry (GC/MS). Using our optimized method, the median concentration of nicotine in the dust of self-reported nonsmoking homes was 11.7 ng/mg while that of smoking homes was 43.4 ng/mg. We found a substantially positive association (r=0.67, P<0.0001) between house dust nicotine concentrations and the numbers of cigarettes smoked daily. Optimized analytical methods showed a feasibility to detect nicotine in house dust. Our results indicated that the measurement of nicotine in house dust can be used potentially as a marker of longer term SHS exposure

A lipid-polymeric hybrid nanoparticle-based next-generation nicotine nanovaccine was rationalized in this study to combat nicotine addiction. A series of nanovaccines, which had nicotine-haptens localized on carrier protein (LPKN), nanoparticle surface (LPNK), or both (LPNKN), were designed to study the impact of hapten localization on their immunological efficacy. All three nanovaccines were efficiently taken up and processed by dendritic cells. LPNKN induced a significantly higher immunogenicity against nicotine and a significantly lower anti-carrier protein antibody level compared to LPKN and LPNK. Meanwhile, it was found that the anti-nicotine antibodies elicited by LPKN and LPNKN bind nicotine stronger than those elicited by LPKN, and LPNK and LPNKN resulted in a more balanced Th1-Th2 immunity than LPKN. Moreover, LPNKN exhibited the best ability to block nicotine from entering the brain of mice. Collectively, the results demonstrated that the immunological efficacy of the hybrid nanoparticle-based nicotine vaccine could be enhanced by modulating hapten localization, providing a promising strategy to combatting nicotine addiction.

Parent-child discrepancies in the assessment of children's and adolescents' happiness.

López-Pérez, Belén; Wilson, Ellie L

2015-11-01

In this study, we assessed parent-child agreement in the perception of children's general happiness or well-being in typically developing children (10- and 11-year-olds, n = 172) and adolescents (15- and 16-year-olds, n = 185). Despite parent and child reporters providing internally consistent responses in the General Happiness single-item scale and the Oxford Happiness Questionnaire-Short Form, their perceptions about children's and adolescents' general happiness did not correlate. Parents of 10- and 11-year-olds significantly overestimated children's happiness, supporting previous literature on the parents' positivity bias effect. However, parents of 15- and 16-year-olds showed the reverse pattern by underestimating adolescents' happiness. Furthermore, parents' self-reported happiness or well-being (reported 6 months later) significantly correlated with their estimations of children's and adolescents' happiness. Therefore, these results suggest a potential parents' "egocentric bias" when estimating their children's happiness. These findings are discussed in terms of their theoretical and applied implications for research into child-parent relationships. Copyright © 2015 Elsevier Inc. All rights reserved.

This randomized-controlled trial investigated the effect of physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. Results of this study on 120 male and female volunteers showed that an 8-week group physical exercise programme was significantly effective in older adults' happiness. Findings showed that physical exercise programme is so beneficial for increasing older adults' happiness. Physical activity is associated with well-being and happiness. The purpose of this study was to determine the effects of an 8-week long physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. This was a randomized control trial study. The participants consisted of a group of 120 male and female volunteers (mean ± SD age: 71 ± 5.86 years) in a convenience sampling among older adults in public parks in Nowshahr, Iran. We randomly allocated them into experimental (n = 60) and control (n = 60) groups. A validated instrument was used to measure well-being and happiness [Oxford Happiness Inventory (OHI)]. Respondents were asked to complete the OHI before and 2 months after implementing PEP. The 8-week PEP was implemented with the intervention group. The statistical analysis of the data was conducted using paired t-test, Fisher's exact test and χ(2). Before the intervention, there was no significant difference in the happiness mean score between the case and control groups; however, after implementing PEP, happiness significantly improved among the experimental group (P = 0.001) and did not improve within the control group (P = 0.79). It can be concluded that PEP had positive effects on happiness among older adults. Planning and implementing of physical activity is so important for older happiness. © 2014 John Wiley & Sons Ltd.

"So Happy I Could Shout!" and "So Happy I Could Cry!" Dimorphous expressions represent and communicate motivational aspects of positive emotions.

Happiness can be expressed through smiles. Happiness can also be expressed through physical displays that without context, would appear to be sadness (tears, downward turned mouths, and crumpled body postures) and anger (clenched jaws, snarled lips, furrowed brows, and pumped fists). These seemingly incongruent displays of happiness, termed dimorphous expressions, we propose, represent and communicate expressers' motivational orientations. When participants reported their own aggressive expressions in positive or negative contexts, their expressions represented positive or negative emotional experiences respectively, imbued with appetitive orientations (feelings of wanting to go). In contrast, reported sad expressions, in positive or negative contexts, represented positive and negative emotional experiences respectively, imbued with consummatory orientations (feelings of wanting to pause). In six additional experiments, participant observers interpreted that aggression displayed in positive contexts signalled happy-appetitive states, and sadness displayed in positive contexts signalled happy-consummatory states. Implications for the production and interpretation of emotion expressions are discussed.

Preclinical studies have shown that repeated stress experiences can result in an increase in the locomotor response to the subsequent administration of drugs of abuse, a phenomenon that has been termed behavioral cross-sensitization. Behavioral sensitization reflects neuroadaptive processes associated with drug addiction and drug-induced psychosis. Although crosssensitization between stress- and drug-induced locomotor activity has been clearly demonstrated in adult rats, few studies have evaluated this phenomenon in adolescent rats. In the present study, we determined if the simultaneous exposure to stress and nicotine was capable of inducing behavioral sensitization to nicotine in adolescent and adult rats. To this end, adolescent (postnatal day (P) 28-37) and adult (P60-67) rats received nicotine (0.4 mg/kg, sc) or saline (0.9% NaCl, sc) and were immediately subjected to restraint stress for 2 h once a day for 7 days. The control group for stress was undisturbed following nicotine or saline injections. Three days after the last exposure to stress and nicotine, rats were challenged with a single dose of nicotine (0.4 mg/kg, sc) or saline and nicotine-induced locomotion was then recorded for 30 min. In adolescent rats, nicotine caused behavioral sensitization only in animals that were simultaneously exposed to stress, while in adult rats nicotine promoted sensitization independently of stress exposure. These findings demonstrate that adolescent rats are more vulnerable to the effects of stress on behavioral sensitization to nicotine than adult rats.

Previously, studies from our lab have shown that while acute nicotine administered prior to training and testing enhances contextual fear conditioning, acute nicotine injections prior to extinction sessions impair extinction of contextual fear. Although there is also strong evidence showing that the acute nicotine's enhancing effects on contextual fear conditioning require high-affinity α4β2 nicotinic acetylcholine receptors (nAChRs), it is unknown which nAChR subtypes are involved in the acute nicotine-induced impairment of contextual fear extinction. In this study, we investigated the effects of acute nicotine administration on contextual fear extinction in knock-out (KO) mice lacking α4, β2 or α7 subtypes of nAChRs and their wild-type (WT) littermates. Both KO and WT mice were first trained and tested for contextual fear conditioning and received a daily contextual extinction session for 4 days. Subjects received intraperitoneal injections of nicotine (0.18 mg/kg) or saline 2-4 min prior to each extinction session. Our results showed that the mice that lack α4 and β2 subtypes of nAChRs showed normal contextual fear extinction but not the acute nicotine-induced impairment while the mice that lack the α7 subtype showed both normal contextual extinction and nicotine-induced impairment of contextual extinction. In addition, control experiments showed that acute nicotine-induced impairment of contextual fear extinction persisted when nicotine administration was ceased and repeated acute nicotine administrations alone did not induce freezing behavior in the absence of context-shock learning. These results clearly demonstrate that high-affinity α4β2 nAChRs are necessary for the effects of acute nicotine on contextual fear extinction. Copyright © 2015 Elsevier Inc. All rights reserved.

In order to model students' happiness, we apply machine learning methods to data collected from undergrad students monitored over the course of one month each. The data collected include physiological signals, location, smartphone logs, and survey responses to behavioral questions. Each day, participants reported their wellbeing on measures including stress, health, and happiness. Because of the relationship between happiness and depression, modeling happiness may help us to detect individuals who are at risk of depression and guide interventions to help them. We are also interested in how behavioral factors (such as sleep and social activity) affect happiness positively and negatively. A variety of machine learning and feature selection techniques are compared, including Gaussian Mixture Models and ensemble classification. We achieve 70% classification accuracy of self-reported happiness on held-out test data.

Background and Purpose Chronic treatment can differentially impact the effects of pharmacologically related drugs that differ in receptor selectivity and efficacy. Experimental Approach The impact of daily nicotine treatment on the effects of nicotinic ACh receptor (nAChR) agonists was examined in two groups of rhesus monkeys discriminating nicotine (1.78 mg·kg−1 base weight) from saline. One group received additional nicotine treatment post‐session (1.78 mg·kg−1 administered five times daily, each dose 2 h apart; i.e. Daily group), and the second group did not (Intermittent group). Key Results Daily repeated nicotine treatment produced a time‐related increase in saliva cotinine. There was no significant difference in the ED50 values of the nicotine discriminative stimulus between the Daily and Intermittent group. Mecamylamine antagonized the effects of nicotine, whereas dihydro‐β‐erythroidine did not. Midazolam produced 0% nicotine‐lever responding. The nAChR agonists epibatidine, RTI‐36, cytisine and varenicline produced >96% nicotine‐lever responding in the Intermittent group. The respective maximum effects in the Daily group were 100, 72, 59 and 28%, which shows that the ability of varenicline to produce nicotine‐like responding was selectively decreased in the Daily as compared with the Intermittent group. When combined with nicotine, both varenicline and cytisine increased the potency of nicotine to produce discriminative stimulus effects. Conclusion and Implications Nicotine treatment has a greater impact on the sensitivity to the effects of varenicline as compared with some other nAChR agonists. Collectively, these results strongly suggest that varenicline differs from nicotine in its selectivity for multiple nAChR subtypes. PMID:27667659

Full Text Available Background Happiness is a lasting state and is associated with the absence of negative emotions, the presence of positive emotions, life satisfaction, social engagement and objectives in life. Researchers have demonstrated the benefits of happiness in many aspects of life, but few studies have been conducted within psychiatry.Objectives To develop a critical literature review of studies on happiness and health in order to bring some further and useful information to psychiatry updating the article “Happiness: a review” published in 2007 in Revista de Psiquiatria Clínica.Methods Computational searching was undertaken of digital data basis (PubMed and SciELO using the keywords “happiness” and “health”. One hundred twenty-seven papers published between 2004 and 2014 were found, but only 76 had the keywords in the title or abstract and with this were selected.Results Personality traits, such as self-direction; being married; being involved in physical and leisure activities; higher educational backgrounds and intelligence quotient; religiosity, volunteering and altruism; good physical and mental health; were positively related to happiness.Discussion Analysis of the concept of happiness and its associated emotions may be more complex than describing the symptoms of psychiatric disorders. Despite this, the study of happiness brings several positive implications for psychiatry.

Full Text Available Abstract Background Considering the extreme shortage of smoking cessation services in China, and the acceptability, feasibility and efficacy of mobile phone-based text message interventions for quitting smoking in other countries, here we propose a study of “the efficacy of mobile phone-based text message interventions (‘Happy Quit’ for smoking cessation in China”. The primary objective of this proposed project is to assess whether a program of widely accessed mobile phone-based text message interventions (‘Happy Quit’ will be effective at helping people in China who smoke, to quit. Based on the efficacy of previous studies in smoking cessation, we hypothesize that ‘Happy Quit’ will be an effective, feasible and affordable smoking cessation program in China. Methods/Design In this single-blind, randomized trial, undertaken in China, about 2000 smokers willing to make a quit attempt will be randomly allocated, using an independent telephone randomization system that includes a minimization algorithm balancing for sex (male, female, age (19–34 or >34 years, educational level (≤ or >12 years, and Fagerstrom score for nicotine addiction (≤5, >5, to ‘Happy Quit’, comprising motivational messages and behavioral-change support, or to a control group that receives text messages unrelated to quitting. Messages will be developed to be suitable for Chinese. A pilot study will be conducted before the intervention to modify the library of messages and interventions. The primary outcome will be self-reported continuous smoking abstinence. A secondary outcome will be point prevalence of abstinence. Abstinence will be assessed at six time points (4, 8, 12, 16, 20 and 24 weeks post-intervention. A third outcome will be reductions in number of cigarettes smoked per day. Discussion/Implications The results will provide valuable insights into bridging the gap between need and services received for smoking cessation interventions and

Happiness, Psychology, and Degrees of Realism.

Science.gov (United States)

Lavazza, Andrea

2016-01-01

The recent emphasis on a realist ontology that cannot be overshadowed by subjectivist or relativist perspectives seems to have a number of consequences for psychology as well. My attempt here is to analyse the relationship between happiness as a state of the individual and the states of the external world and the brain events related to (or, in some hypotheses, causally responsible for) its occurrence. It can be maintained that different degrees of realism are suitable to describe the states of happiness and this fact might have relevant psychological implications, namely for the so-called positive psychology. This is especially true now that there are methods available to induce subjective states of happiness unrelated to the external conditions usually taken to be linked to such states.

Compassion, Mindfulness, and the Happiness of Healthcare Workers.

Benzo, Roberto P; Kirsch, Janae L; Nelson, Carlie

Decreased well-being of healthcare workers expressed as stress and decreased job satisfaction influences patient safety, patient satisfaction, and cost containment. Self-compassion has garnered recent attention due to its positive association with well-being and happiness. Discovering novel pathways to increase the well-being of healthcare workers is essential. This study sought to explore the influence of self-compassion on employee happiness in healthcare professionals. A total of 400 participants (mean age = 45 ± 14, 65% female) healthcare workers at a large teaching hospital were randomly asked to complete questionnaires assessing their levels of happiness and self-compassion, life conditions, and habits. Participants completed the Happiness Scale and Self-Compassion Scales, the Five Facet Mindfulness Questionnaire as well as variables associated with well-being: relationship status, the number of hours spent exercising a week, attendance at a wellness facility, and engagement in a regular spiritual practice. Self-compassion was significantly and independently associated with perceived happiness explaining 39% of its variance after adjusting for age, marital status, gender, time spent exercising, and attendance to an exercise facility. Two specific subdomains of self-compassion from the instrument used, coping with isolation and mindfulness, accounted for 95% of the self-compassion effect on happiness. Self-compassion is meaningfully and independently associated with happiness and well-being in healthcare professionals. Our results may have practical implications by providing specific self-compassion components to be targeted in future programs aimed at enhancing well-being in healthcare professionals.

African-American (AA) smokers are at disproportionate risk of tobacco dependence, utilizing smoking to regulate stress, and poor cessation outcomes. Positive emotional traits may function as coping factors that buffer the extent to which dependence increases vulnerability to adverse responses to acute tobacco abstinence (i.e., tobacco withdrawal). This laboratory study examined subjective happiness (SH; dispositional orientation towards frequent and intense positive affect [PA] and life satisfaction) as a moderator of the relation between tobacco dependence and subjective and behavioral abstinence effects among AA smokers. AA smokers (N=420, 39.0% female) completed self-report measures of tobacco dependence and SH followed by two counterbalanced experimental sessions (non-abstinent vs. 16-hr abstinent) involving self-report measures of composite withdrawal, urge to smoke, and mood, and a behavioral smoking task in which participants could: (a) earn money to delay smoking reinstatement, and (b) subsequently purchase cigarettes to smoke. Tobacco dependence was positively associated with increased abstinence effects in composite withdrawal, urge to smoke, PA, and latency to smoking reinstatement (pssmokers. The current study contributes to a growing body of literature examining the potentially advantageous role of positive emotional traits to smokers. We do so by identifying a relatively understudied psychological construct within tobacco research-subjective happiness-that may suppress the extent to which more severe tobacco dependence increases risk for subjective withdrawal-related distress during acute smoking abstinence in African American smokers. In doing so, the study provides a primer for future targeting of subjective happiness and other positive emotional traits as means to understand and treat acute tobacco abstinence effects among dependent African American smokers. © The Author 2017.

Nicotine deposited on the surfaces has been shown to react with airborne chemicals leading to formation of carcinogens and contributing to thirdhand exposure. While prior studies revealed nicotine residues in tobacco smokers' homes, none have examined the nicotine residue in electronic cigarette (e-cigarette) users' homes. We measured nicotine on the surfaces in households of 8 e-cigarette users, 6 cigarette smokers, and 8 non-users of nicotine-containing products in Western New York, USA. Three surface wipe samples were taken from the floor, wall and window. Nicotine was extracted from the wipes and analyzed using gas chromatography. Half of the e-cigarette users' homes had detectable levels of nicotine on surfaces whereas nicotine was found in all of the tobacco cigarette smokers' homes. Trace amounts of nicotine were also detected in half of the homes of non-users of nicotine-containing products. Nicotine levels in e-cigarette users homes was significantly lower than that found in cigarette smokers homes (average concentration 7.7±17.2 vs. 1303±2676 μg/m2; pe-cigarette users and non-users (p>0.05). Nicotine is a common contaminant found on indoor surfaces. Using e-cigarettes indoors leads to significantly less thirdhand exposure to nicotine compared to smoking tobacco cigarettes.

Full Text Available This work proposes a platform for estimating personality and happiness. Starting from Eysenck's theory about human's personality, authors seek to provide a platform for collecting text messages from social media (Whatsapp, and classifying them into different personality categories. Although there is not a clear link between personality features and happiness, some correlations between them could be found in the future. In this work, we describe the platform developed, and as a proof of concept, we have used different sources of messages to see if common machine learning algorithms can be used for classifying different personality features and happiness.

Nicotine, adolescence, and stress: A review of how stress can modulate the negative consequences of adolescent nicotine abuse.

Science.gov (United States)

Holliday, Erica; Gould, Thomas J

2016-06-01

In order to continue the decline of smoking prevalence, it is imperative to identify factors that contribute to the development of nicotine and tobacco addiction, such as adolescent initiation of nicotine use, adolescent stress, and their interaction. This review highlights the biological differences between adolescent and adults in nicotine use and resulting effects, and examines the enduring consequences of adolescent nicotine administration. A review of both clinical and preclinical literature indicates that adolescent, but not adult, nicotine administration leads to increased susceptibility for development of long-lasting impairments in learning and affect. Finally, the role stress plays in normal adolescent development, the deleterious effects stress has on learning and memory, and the negative consequences resulting from the interaction of stress and nicotine during adolescence is reviewed. The review concludes with ways in which future policies could benefit by addressing adolescent stress as a means of reducing adolescent nicotine abuse. Copyright © 2016 Elsevier Ltd.

Full Text Available The paper aims to explore how happiness, leisure and tourism play role in modern life, and how they are related to household budget. While in the past household budget was totally allotted to the necessities of food, clothing and shelter, nowadays, some portion of the household budget needs to be allotted to leisure and tourism activities ___ leading to happiness. While in the West it is done so, in the developing countries, there is still a long way to go, to achieve that goal. However, tourism has become a popular global happiness and leisure activity. As reported, in 2011, there were over 983 million international tourist arrivals worldwide (UNTWO, 2012. Tourism as a way to happiness is important and vital in some cases. It brings large amount of income in payment for goods and services available. The present paper partly investigates happiness, leisure and tourism in Tehran, Iran through assessing household budget. In that, 623 households were empirically studied to find out happiness, leisure and tourism vs household budget in Iran.

Nicotine harms adolescent brain development and contributes to addiction. Some adolescents report using nicotine-free e-cigarettes, but the accuracy of their reporting is unclear. We explored adolescents' use of nicotine-free e-cigarettes and understanding of chemicals in e-cigarettes, including nicotine. Using social media, we recruited 1589 US adolescents (aged 15-17) who reported past 30-day use of e-cigarettes in 2016. We assessed perceptions of the nicotine source in e-liquid and whether e-cigarette aerosol is just "water vapor." We explored differences among adolescents who usually used e-cigarettes with nicotine (n = 473) and without nicotine (n = 452). We used weights to calibrate our sample to the Youth Risk Behavior Survey. Twenty-nine percent usually used e-cigarettes without nicotine, 28% with nicotine, 39% with "both," and 5% were "not sure." Few participants (17% of non-nicotine users vs. 34% of nicotine users, p e-cigarette aerosol was just water vapor were more likely to usually use without nicotine. Older adolescents and current tobacco users were less likely to usually use without nicotine. The adolescents who reported usually using e-cigarettes without nicotine had poorer knowledge of e-cigarettes. This lack of understanding could contribute to inaccurate reporting of nicotine use. Most youth thought the nicotine in e-cigarettes was artificial, potentially indicating a belief that this nicotine is "safer." The US Food & Drug Administration will require nicotine warnings on e-cigarettes in 2018; a complementary educational campaign could address youths' misperceptions about nicotine and other chemicals in e-cigarette aerosol.

Happiness is regarded as one of the most fundamental human goals. Given recent reports that positive feelings are contagious (e.g., the presence of a happy person enhances others' happiness) because of the human ability to empathize (i.e., sharing emotions), empathic ability may be a key factor in increasing one's own subjective level of happiness. Based on previous studies indicating that a single nucleotide polymorphism in the serotonin 2A receptor gene [HTR2A rs6311 guanine (G) vs. adenine (A)] is associated with sensitivity to emotional stimuli and several mental disorders such as depression, we predicted that the polymorphism might be associated with the effect of sharing happiness. To elucidate the neural and genetic correlates of the effect of sharing happiness, we first performed functional magnetic resonance imaging (fMRI) during a “happy feelings” evocation task (emotional event imagination task), during which we manipulated the valence of the imagined event (positive, neutral, or negative), as well as the presence of a friend experiencing a positive-valence event (presence or absence). We recruited young adult women for this fMRI study because empathic ability may be higher in women than in men. Participants felt happier (p happiness (neutral/presence condition) than those with the AA genotype. In a follow-up study with a vignette-based questionnaire conducted in a relatively large sample, male and female participants were presented with the same imagined events wherein their valence and the presence of a friend were manipulated. Results showed genetic differences in happiness-related empathy regardless of sex (p happiness by modulating the activity of the mentalizing/theory-of-mind network. PMID:29311795

Vitamin E Nicotinate

Kimbell R. Duncan

Full Text Available Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and converted into free α-tocopherol prior to absorption in the intestinal tract. Because its functions are relevant to many chronic diseases, vitamin E has been extensively studied in respect to a variety of diseases as well as cosmetic applications. The forms of vitamin E most studied are natural α-tocopherol and the esters α-tocopheryl acetate and α-tocopheryl succinate. A small number of studies include or focus on another ester form, α-tocopheryl nicotinate, an ester of vitamin E and niacin. Some of these studies raise the possibility of differences in metabolism and in efficacy between vitamin E nicotinate and other forms of vitamin E. Recently, through metabolomics studies, we identified that α-tocopheryl nicotinate occurs endogenously in the heart and that its level is dramatically decreased in heart failure, indicating the possible biological importance of this vitamin E ester. Since knowledge about vitamin E nicotinate is not readily available in the literature, the purpose of this review is to summarize and evaluate published reports, specifically with respect to α-tocopheryl nicotinate with an emphasis on the differences from natural α-tocopherol or α-tocopheryl acetate.

Our aim was to assess the potential relationships among happiness, physical activity, and smoking initiation among undergraduate medical students in Saudi Arabia. We performed a cross-sectional study of randomly selected first- to fifth-year undergraduate medical students. Smoking initiation was defined as "ever trying smoking a cigarette, waterpipe, cigar/cigarillo, or other type of tobacco, even one or 2 puffs." The short scale Oxford Happiness Questionnaire was used to assess each student's happiness. Multivariate logistic regression analysis was performed. Of the 406 students surveyed (208 boys, 198 girls), 86 (21.1%) had initiated smoking. We found an interaction between physical activity (PA) and happiness on smoking initiation (p-interaction = .012). Among boys with low levels of PA, lower levels of happiness were associated with a greater likelihood of smoking initiation (OR = 5.8, 95%CI = 1.9 - 17.5). Also, high levels of PA increased the chance of smoking initiation among male students with high levels of happiness (OR = 5.6, 95%CI = 2.1 - 14.5). Our results suggest that young men with low levels of happiness and low levels of PA, as well as high levels of PA and high levels of happiness, may be targeted as a priority population in tobacco control intervention programs.

Why are you happy with impulse buying? Evidence from Indonesia

Full Text Available Happiness is an ideal condition needed by everyone. In the real life, happiness comes not only from the harmony in the home but also from the exciting environment or atmosphere outside the home, such as impulse buying. When someone makes impulse buying, she could feel the happiness be-cause she gets something she wants. This means that when someone makes a purchase, she will experience happiness. This study aimed to examine the variables that affect impulse buying which may also affect the happiness. It is assumed that the experience and the pleasant shopping atmosphere affect the impulse buying and, as a result, the impulse buying affects happiness. The samples in this study were 150 women making purchases of fashion products at malls in Surabaya. The hypothesis testing was conducted by using Structural Equation Modelling. The test results indicated the hypothesis 1 stating that the experiential marketing influenced the impulse buying and hypothesis 2 stating that the shopping enjoyment affected the impulse buying were accepted. Further, hypothesis 3 were also accepted, stating that the impulse buying influenced happiness.

Nicotine Replacement Therapy (NRT) is recommended as a frontline smoking cessation tool for people attending mental health and substance dependence treatment services. Previous research suggests that NRT is underutilized in these settings. To improve the use of NRT amongst people attending residential treatment for substance use disorders (SUDs) it is important that the factors influencing smokers' decisions to use NRT are understood. The study aimed to examine: (1) smoking cessation strategies used by participants in previous quit attempts, (2) participants' attitudes towards NRT (i.e. safety concerns and perceived efficacy), and (3) the predictors of participants' intention to use NRT to support future quit attempts. Participants completed a cross-sectional survey that examined their smoking behaviours, previous experiences using smoking cessation strategies, attitudes and beliefs regarding NRT, and intention to use NRT as part of future quit attempts (N = 218). All participants were attending residential treatment for substance use disorders provided by We Help Ourselves (WHOS), a large provider of specialist alcohol and other drug treatment in Australia. The majority of respondents (98%) reported that they had smoked regularly in their lifetime, and 89% were current smokers. Forty-five percent of the current smokers reported that they had previously used NRT to support a quit attempt, with 54% reporting that they intended to use NRT to support a future quit attempt. Intentions to use NRT were not related to the participants' mental health status or the participants' perceptions regarding the safety or potential drawbacks associated with using NRT. However, participants were more likely to report that they would use NRT to support future quit attempts if they were female, had previously used NRT and perceived NRT to be effective. Improving the use of evidence based smoking cessation strategies within substance use treatment continues to be a priority. To enhance

Co-users of alcohol and nicotine are the largest group of polysubstance users worldwide. Commonalities in mechanisms of action for ethanol (EtOH) and nicotine proposes the possibility of developing a single pharmacotherapeutic to treat co-use. Toward developing a preclinical model of co-use, female alcohol-preferring (P) rats were trained for voluntary EtOH drinking and i.v. nicotine self-administration in three phases: (1) EtOH alone (0 vs. 15%, two-bottle choice), (2) nicotine alone (0.03 mg/kg/infusion, active vs. inactive lever), and (3) concurrent access to both EtOH and nicotine. Using this model, we examined the effects of (1) varenicline, a nicotinic acetylcholine receptor (nAChR) partial agonist with high affinity for the α4β2* subtype; (2) r-bPiDI, a subtype-selective antagonist at α6β2* nAChRs; and (3) (R)-modafinil, an atypical inhibitor of the dopamine transporter (DAT). In phases 1 and 2, pharmacologically relevant intake of EtOH and nicotine was achieved. In the concurrent access phase (phase 3), EtOH consumption decreased while nicotine intake increased relative to phases 1 and 2. For drug pretreatments, in the EtOH access phase (phase 1), (R)-modafinil (100 mg/kg) decreased EtOH consumption, with no effect on water consumption. In the concurrent access phase, varenicline (3 mg/kg), r-bPiDI (20 mg/kg), and (R)-modafinil (100 mg/kg) decreased nicotine self-administration but did not alter EtOH consumption, water consumption, or inactive lever pressing. These results indicate that therapeutics which may be useful for smoking cessation via selective inhibition of α4β2* or α6β2* nAChRs, or DAT inhibition, may not be sufficient to treat EtOH and nicotine co-use.

Full Text Available We propose to use real-time EEG signal to classify happy and unhappy emotions elicited by pictures and classical music. We use PSD as a feature and SVM as a classifier. The average accuracies of subject-dependent model and subject-independent model are approximately 75.62% and 65.12%, respectively. Considering each pair of channels, temporal pair of channels (T7 and T8 gives a better result than the other area. Considering different frequency bands, high-frequency bands (Beta and Gamma give a better result than low-frequency bands. Considering different time durations for emotion elicitation, that result from 30 seconds does not have significant difference compared with the result from 60 seconds. From all of these results, we implement real-time EEG-based happiness detection system using only one pair of channels. Furthermore, we develop games based on the happiness detection system to help user recognize and control the happiness.

We collected two nicotine samples – one nicotine sampling filter was placed in-line after the collection of PM2.5 and the other stood alone. The overall correlation between the two nicotine filter levels was 0.99. The nicotine collected on the “stand-alone” filter was slightly greater than that on the “in-line” filter (mean difference = 1.10 μg/m3, but the difference was statistically significant only when PM2.5 was low (≤ 50 μg/m3. It is therefore important to account for personal and secondhand smoke exposure while assessing occupational and environmental PM.

Pursuing happiness can paradoxically impair well-being. Here, we propose the potential downsides to pursuing happiness may be specific to individualistic cultures. In collectivistic (vs. individualistic) cultures, pursuing happiness may be more successful because happiness is viewed – and thus pursued – in relatively socially-engaged ways. In four geographical regions that vary in level of collectivism (U.S., Germany, Russia, East Asia), we assessed participants’ well-being, motivation to pursue happiness, and to what extent they pursued happiness in socially-engaged ways. Motivation to pursue happiness predicted lower well-being in the U.S., did not predict well-being in Germany, and predicted higher well-being in Russia and in East Asia. These cultural differences in the link between motivation to pursue happiness and well-being were explained by cultural differences in the socially-engaged pursuit of happiness. These findings suggest that culture shapes whether the pursuit of happiness is linked with better or worse well-being, perhaps via how people pursue happiness. PMID:26347945

FORCED HAPPINESS AS A MODERN SOCIO AND CULTURAL IMPERATIVE

Directory of Open Access Journals (Sweden)

H. V. Khodus

2015-12-01

Full Text Available Purpose. In this article is an attempt to "read" cultural code of the phenomenon of happiness in actual social circumstances. The research was primarily focused on the specifics of the contemporary cultural situation, which determines the emotional infrastructure of individuals’ life. Methodology. The number of concepts that were proposed by M. Foucault, N. Elias, in particular – «configurationally balance of power», «culture of yourself», «take care of yourself», «practice of yourself», "the discourse of power/knowledge" are proposed as a heuristic resource that allows to comprehend the transit of value-semantic codes of the happiness phenomenon. Such analytical optics enable reading of contemporary social reality as a discursive space that permeated with visual aestheticization of various emotions, legitimized with knowledge/power. This disciplinary discourse not only codifies the "correct" expression of emotions, but also culturally encodes the hierarchy of these "correct" emotions. Scientific novelty. It is proved that a characteristic feature of current modernity (available in Ukrainian realities is the change in happiness status, its transformation into "normative" emotion that individuals should feel and show. In other words, the cult of happiness becomes dominant cultural imperative, a duty, acting as a moral duty. It is argued that "the forced happiness" is a social effect of the therapeutic culture, which streamlines the emotional life of the individual, interpersonal relationships, scenarios of success and happiness. The key role of cultural mediators, commercial narratives (Internet, media in the design and promotion of the ideology of "forced happiness" is justified. Conclusions. The proposed research approach allows deconstructing the emotional regime of modernity in the aspect of problematization the phenomenon of happiness. The idea is that the right to happiness, to private pleasure and self-care are the basic ideas

The paper focuses on happiness inequality, an issue rather neglected in the literature. We analyze the increase in happiness inequality observed in Germany between 1991 and 2007 by means of the German Socio-Economic Panel (GSOEP) database. We make use of a recent methodology that allows decomposing the change in happiness inequality into the composition and the coefficient effect for each covariate. We find that the increase in happiness inequality is mainly driven by changes in the compositi...

Views and Preferences for Nicotine Products as an Alternative to Smoking: A Focus Group Study of People Living with Mental Disorders

2016-11-01

Full Text Available Aims and Background: People living with mental disorders experience a disproportionately higher burden of tobacco-related disease than the general population. Long-term substitution with less harmful nicotine products could reduce the tobacco-related harm among this population. This study investigated the views and preferences of people with mental health disorders about different nicotine products and their use as long-term substitutes for cigarettes. Methods: Semi-structured focus group discussion followed by a brief questionnaire. The discussion transcripts were analysed for content and themes and quantitative data summarised with descriptive statistics. Results: Twenty-nine participants took part in four focus groups. Vaping devices were the most acceptable nicotine products discussed; however preferences for nicotine products were individual and varied along aesthetic, pragmatic, sensory and symbolic dimensions. The concept of tobacco harm reduction was unfamiliar to participants, however they generally agreed with the logic of replacing cigarettes with less harmful nicotine products. Barriers to activating tobacco harm reduction included the symbolism of smoking and quitting; the importance placed on health; the consumer appeal of alternatives; and cost implications. Discussion and Conclusions: Engaging this population in tobacco harm reduction options will require communication that challenges black and white thinking (a conceptual framework in which smoking cigarettes or quitting all nicotine are the only legitimate options as in practice this serves to support the continuance of smoking. Consumers should be encouraged to trial a range of nicotine products to find the most acceptable alternative to smoking that reduces health harms. Providing incentives to switch to nicotine products could help overcome barriers to using less harmful nicotine products among mental health consumers.

The relevance of the study of happiness and stress in nurses has been emphasized. In this sense, the intelligent use of hardiness is enable nurses to cope better with stress and contribute to being happier. This study aimed to examine the relationship among hardiness, perceived stress, and happiness in nurses. Moreover, we examined the mediator role of hardiness on the relationship between perceived stress and happiness in nurses. Our study revealed that hardi-attitude nurses evaluate situations as less stressful which results in a higher happiness. This study showed hardiness as being a protective factor against perceived stress and a facilitating factor for happiness in nurses. The findings could be important in training future nurses so that hardiness can be imparted, thereby giving them the ability to control their stress. Nursing is a stressful occupation with high levels of stress within the health professions. Given that hardiness is an important construct to enable nurses to cope better with stress and contribute to being happier; therefore, it is necessary we advance our knowledge about the aetiology of happiness, especially the role of hardiness in decreasing stress levels and increasing happiness. The present study sought to investigate the role of hardiness as a mediator between perceived stress and happiness. The participants, comprising 252 nurses from six private hospitals in Tehran, completed the Personal Views Survey, the Perceived Stress Scale, and the Oxford Happiness Inventory. Structural Equation Modelling (SEM) was used to analyse the data and answer the research hypotheses. As expected, hardiness partially mediated between perceived stress and happiness among nurses, and nurses with low levels of perceived stress were more likely to report greater hardiness and happiness. In addition, nurses with high levels of hardiness were more likely to report happiness. This study showed hardiness as being a protective factor against perceived stress and

Full Text Available Researcher takes particular interest to discover the respondents’ orientation towards happiness based on where the respondent was raised. The study involves 467 senior high school students with ages ranging from 14-17 years old. The data is analyzed using an adapted society psychological approach. The results shows that adolescents raised in rural areas are consider the family to be a factor that contributes to their happiness. Second, achievement is also a factor that leads to happiness. However for the category, to love and be loved, adolescents growing in urban areas place this as a factor that leads to happiness. Similar with spirituality, friends and leisure time are factors that make adolescents raised in urban areas to become happy. Nevertheless, the results of cross tabulation with Pearson chi square test scoring demonstrates that no correlations exist between adolescent happiness raised from urban or rural areas.

Fetal Nicotine Exposure Increases Preference for Nicotine Odor in Early Postnatal and Adolescent, but Not Adult, Rats

Human studies demonstrate a four-fold increased possibility of smoking in the children of mothers who smoked during pregnancy. Nicotine is the active addictive component in tobacco-related products, crossing the placenta and contaminating the amniotic fluid. It is known that chemosensory experience in the womb can influence postnatal odor-guided preference behaviors for an exposure stimulus. By means of behavioral and neurophysiologic approaches, we examined whether fetal nicotine exposure, using mini-osmotic pumps, altered the response to nicotine odor in early postnatal (P17), adolescent (P35) and adult (P90) progeny. Compared with controls, fetal exposed rats displayed an altered innate response to nicotine odor that was evident at P17, declined in magnitude by P35 and was absent at P90 - these effects were specific to nicotine odor. The behavioral effect in P17 rats occurred in conjunction with a tuned olfactory mucosal response to nicotine odor along with an untoward consequence on the epithelial response to other stimuli – these P17 neural effects were absent in P35 and P90 animals. The absence of an altered neural effect at P35 suggests that central mechanisms, such as nicotine-induced modifications of the olfactory bulb, bring about the altered behavioral response to nicotine odor. Together, these findings provide insights into how fetal nicotine exposure influences the behavioral preference and responsiveness to the drug later in life. Moreover, they add to a growing literature demonstrating chemosensory mechanisms by which patterns of maternal drug use can be conveyed to offspring, thereby enhancing postnatal vulnerability for subsequent use and abuse.

Objective Nicotine acts in the brain to promote smoking in part by binding to the beta2-containing nicotinic acetylcholine receptors (β2*-nAChRs) and acting in the mesolimbic reward pathway. The effects of nicotine from smoking one tobacco cigarette are significant (80% of β2*-nAChRs occupied for >6h). This likely contributes to the maintenance of smoking dependence and low cessation outcomes. Development of nicotine vaccines provides potential for alternative treatments. We used [123I]5IA-85380 SPECT to evaluate the effect of 3′-AmNic-rEPA on the amount of nicotine that binds to the β2*-nAChRs in the cortical and subcortical regions in smokers. Method Eleven smokers (36years (SD=13); 19cig/day (SD=11) for 10years (SD=7) who were dependent on nicotine (Fagerström Test of Nicotine Dependence score =5.5 (SD=3); plasma nicotine 9.1 ng/mL (SD=5)) participated in 2 SPECT scan days: before and after immunization with 4–400μg doses of 3′-AmNic-rEPA. On SPECT scan days, 3 30-min baseline emission scans were obtained, followed by administration of IV nicotine (1.5mg/70kg) and up to 9 30-min emission scans. Results β2*-nAChR availability was quantified as VT/fP and nicotine binding was derived using the Lassen plot approach. Immunization led to a 12.5% reduction in nicotine binding (F=5.19, df=1,10, p=0.05). Significant positive correlations were observed between nicotine bound to β2*-nAChRs and nicotine injected before but not after vaccination (p=0.05 vs. p=0.98). There was a significant reduction in the daily number of cigarettes and desire for a cigarette (p=.01 and p=.04, respectively). Conclusions This proof-of-concept study demonstrates that immunization with nicotine vaccine can reduce the amount of nicotine binding to β2*-nAChRs and disrupt the relationship between nicotine administered vs. nicotine available to occupy β2*-nAChRs.

Around the world, increases in wealth have produced an unintended consequence: a rising sense of time scarcity. We provide evidence that using money to buy time can provide a buffer against this time famine, thereby promoting happiness. Using large, diverse samples from the United States, Canada, Denmark, and The Netherlands ( n = 6,271), we show that individuals who spend money on time-saving services report greater life satisfaction. A field experiment provides causal evidence that working adults report greater happiness after spending money on a time-saving purchase than on a material purchase. Together, these results suggest that using money to buy time can protect people from the detrimental effects of time pressure on life satisfaction.

Self-centeredness and selflessness: happiness correlates and mediating psychological processes.

Dambrun, Michael

2017-01-01

The main objective of this research was to test central assumptions from the Self-centeredness/Selflessness Happiness Model. According to this model, while self-centered psychological functioning induces fluctuating happiness, authentic-durable happiness results from selflessness. Distinct mediating processes are supposed to account for these relationships: afflictive affects (e.g., anger, fear, jealousy, frustration) in the case of the former, and both emotional stability and feelings of harmony in the case of the latter. We tested these hypotheses in two studies based on heterogeneous samples of citizens ( n  = 547). Factor analyses revealed that self-centeredness (assessed through egocentrism and materialism) and selflessness (assessed through self-transcendence and connectedness to other) were two distinct psychological constructs. Second, while self-centeredness was positively and significantly related to fluctuating happiness, selflessness was positively and significantly related to authentic-durable happiness. Finally, distinct psychological processes mediated these relationships (study 2). On one hand, the relationship between self-centeredness and fluctuating happiness was fully mediated by afflictive affects. On the other hand, emotional stability and the feeling of being in harmony partially mediated the relation between selflessness and authentic-durable happiness.

Full Text Available Objective: The aim of this study is to determine whether individuals’ early maladaptive schemas predict their happiness levels or not and to find out what early maladaptive schemas prevent individuals’ happiness. Method: Relational screening model was used in the study. The study group consisted of the 253 university students; 198 (%78.3 females and 55 (%21.7 males. “The Qxford Happiness Questionnaire Short Form”, developed by Hills and Argyle (2002 and adapted into Turkish by Dogan and Cotok (2011, and “Young Schema Scale-Short Form 3”, developed by Young et al. (2003 and adapted into Turkish by Soygut, Karaosmanoglu, and Cakir (2009 were used to gather the data for the study. Results: According to the results obtained from the study, it was found out that there is a significantly negative relation between happiness and Vulnerability to Harm & Illness, Pessimism/Negativity, Failure, Social Isolation, Emotional Inhibition, Approval-Seeking and Insufficient Self-Control. Moreover, university students’ Pessimism/Negativity and Failure schemas were found to be the predictors of their happiness levels. Conclusion: Families, teachers and mental health workers should work together to resolve the Pessimism/Negativity and Failure early maladaptive schemas of university students’. It is considered as a preventive measure that the education system must be reviewed. [JCBPR 2018; 7(1.000: 7-13

Economic Growth Evens Out Happiness: Evidence from Six Surveys.

2016-09-01

In spite of the great U-turn that saw income inequality rise in Western countries in the 1980s, happiness inequality has fallen in countries that have experienced income growth (but not in those that did not). Modern growth has reduced the share of both the "very unhappy" and the "perfectly happy". Lower happiness inequality is found both between and within countries, and between and within individuals. Our cross-country regression results argue that the extension of various public goods helps to explain this greater happiness homogeneity. This new stylised fact arguably comes as a bonus to the Easterlin paradox, offering a somewhat brighter perspective for developing countries.

Effects of a selective cannabinoid CB2 agonist and antagonist on intravenous nicotine self administration and reinstatement of nicotine seeking.

Directory of Open Access Journals (Sweden)

Full Text Available Over the last decade there have been significant advances in the discovery and understanding of the cannabinoid system along with the development of pharmacologic tools that modulate its function. Characterization of the crosstalk between nicotine addiction and the cannabinoid system may have significant implications on our understanding of the neurobiological mechanisms underlying nicotine dependence. Two types of cannabinoid receptors (CB1 and CB2 have been identified. CB1 receptors are expressed in the brain and modulate drug taking and drug seeking for various drugs of abuse, including nicotine. CB2 receptors have been recently identified in the brain and have been proposed to play a functional role in mental disorders and drug addiction. Our objective was to explore the role of CB2 receptors on intravenous nicotine self administration under two schedules of reinforcement (fixed and progressive ratio and on nicotine seeking induced by nicotine priming or by nicotine associated cues. For this, we evaluated the effects of various doses of the selective CB2 antagonist AM630 (1.25 to 5 mg/kg and CB2 agonist AM1241 (1 to 10 mg/kg on these behavioral responses in rats. Different groups of male Long Evans rats were trained to lever press for nicotine at a unit dose of 30 µg/kg/infusion. Subsequently, animals were randomized using a Latin-square design and injected with either AM1241 or AM630 using a counterbalanced within subject design. Administration of the CB2 ligands did not affect either nicotine-taking nicotine-seeking behavior. Our results do not support the involvement of CB2 receptors in nicotine-taking or nicotine-seeking behavior.

Pursuing happiness can paradoxically impair well-being. Here, the authors propose the potential downsides to pursuing happiness may be specific to individualistic cultures. In collectivistic (vs. individualistic) cultures, pursuing happiness may be more successful because happiness is viewed--and thus pursued--in relatively socially engaged ways. In 4 geographical regions that vary in level of collectivism (United States, Germany, Russia, East Asia), we assessed participants' well-being, motivation to pursue happiness, and to what extent they pursued happiness in socially engaged ways. Motivation to pursue happiness predicted lower well-being in the United States, did not predict well-being in Germany, and predicted higher well-being in Russia and in East Asia. These cultural differences in the link between motivation to pursue happiness and well-being were explained by cultural differences in the socially engaged pursuit of happiness. These findings suggest that culture shapes whether the pursuit of happiness is linked with better or worse well-being, perhaps via how people pursue happiness. (c) 2015 APA, all rights reserved).

In vivo interactions between α7 nicotinic acetylcholine receptor and nuclear peroxisome proliferator-activated receptor-α: Implication for nicotine dependence.

Chronic tobacco use dramatically increases health burdens and financial costs. Limitations of current smoking cessation therapies indicate the need for improved molecular targets. The main addictive component of tobacco, nicotine, exerts its dependency effects via nicotinic acetylcholine receptors (nAChRs). Activation of the homomeric α7 nAChR reduces nicotine's rewarding properties in conditioned place preference (CPP) test and i.v. self-administration models, but the mechanism underlying these effects is unknown. Recently, the nuclear receptor peroxisome proliferator-activated receptor type-α (PPARα) has been implicated as a downstream signaling target of the α7 nAChR in ventral tegmental area dopamine cells. The present study investigated PPARα as a possible mediator of the effect of α7 nAChR activation in nicotine dependence. Our results demonstrate the PPARα antagonist GW6471 blocks actions of the α7 nAChR agonist PNU282987 on nicotine reward in an unbiased CPP test in male ICR adult mice. These findings suggests that α7 nAChR activation attenuates nicotine CPP in a PPARα-dependent manner. To evaluate PPARα activation in nicotine dependence we used the selective and potent PPARα agonist, WY-14643 and the clinically used PPARα activator, fenofibrate, in nicotine CPP and we observed attenuation of nicotine preference, but fenofibrate was less potent. We also studied PPARα in nicotine dependence by evaluating its activation in nicotine withdrawal. WY-14643 reversed nicotine withdrawal signs whereas fenofibrate had modest efficacy. This suggests that PPARα plays a role in nicotine reward and withdrawal and that further studies are warranted to elucidate its function in mediating the effects of α7 nAChRs in nicotine dependence.

Happiness is a topic that ignites both considerable interest and considerable disagreement. Thus far, however, there has been little attempt to characterize people's lay theories about happiness or explore their consequences. We examined whether individual differences in lay theories of happiness would predict empathy. In Studies 1a and 1b, we validated the Lay Theories of Happiness Scale (LTHS), which includes three dimensions: flexibility, controllability, and locus. In Study 2, higher dispositional empathy was predicted by the belief that happiness is flexible, controllable, and internal. In Studies 3 and 4, higher empathy toward a specific target was predicted by the belief that happiness is flexible, uncontrollable, and external In conjunction, Studies 2, 3, and 4 provide evidence that trait and state empathy are separable and can have opposing relationships with people's lay theories. Overall, these findings highlight generalized beliefs that may guide empathic reactions to the unhappiness of others. © 2016 by the Society for Personality and Social Psychology, Inc.

Introduction Nicotine dependence is a disease, and tobacco use is related to 6 million deaths annually worldwide. Recently, in many countries, there has been growing interest in the use of traditional and complementary medicine (T&CM) methods, especially acupuncture, as therapeutic interventions for smoking cessation. The aim of this pilot study is to investigate the effectiveness of T&CM interventions on smoking cessation. Methods and analysis The STOP (Stop Tobacco Programme using traditional Korean medicine) study is designed to be a pragmatic, open-label, randomised pilot trial. This trial will evaluate whether adding T&CM methods (ie, ear and body acupuncture, aromatherapy) to conventional cessation methods (ie, nicotine replacement therapy (NRT), counselling) increases smoking cessation rates. Forty participants over 19 years old who are capable of communicating in Korean will be recruited. They will be current smokers who meet one of the following criteria: (1) smoke more than 10 cigarettes a day, (2) smoke less than 10 cigarettes a day and previously failed to cease smoking, or (3) smoke fewer than 10 cigarettes a day and have a nicotine dependence score (Fagerstrom Test for Nicotine Dependence) of 4 points or more. The trial will consist of 4 weeks of treatment and a 20 week follow-up period. A statistician will perform the statistical analyses for both the intention-to-treat (all randomly assigned participants) and per-protocol (participants who completed the trial without any protocol deviations) data using SAS 9.1.3. Ethics and dissemination This study has been approved by the Institutional Review Board (IRB) of the Dunsan Korean Medicine Hospital of Daejeon University (IRB reference no: DJDSKH-15-BM-11–1, Protocol No. version 4.1.).The protocol will be reapproved by IRB if it requires amendment. The trial will be conducted according to the Declaration of Helsinki, 7th version (2013). This study is designed to minimise the risk to participants

Nicotine is rapidly absorbed from the lung alveoli into systemic circulation during cigarette smoking. However, mechanism underlying nicotine transport in alveolar epithelial cells is not well understood to date. In the present study, we characterized nicotine uptake in lung epithelial cell lines A549 and NCI-H441 and in non-lung epithelial cell lines HepG2 and MCF-7. Characteristics of [ 3 H]nicotine uptake was studied using these cell lines. Nicotine uptake in A549 cells occurred in a time- and temperature-dependent manner and showed saturation kinetics, with a Km value of 0.31mM. Treatment with some organic cations such as diphenhydramine and pyrilamine inhibited nicotine uptake, whereas treatment with organic cations such as carnitine and tetraethylammonium did not affect nicotine uptake. Extracellular pH markedly affected nicotine uptake, with high nicotine uptake being observed at high pH up to 11.0. Modulation of intracellular pH with ammonium chloride also affected nicotine uptake. Treatment with valinomycin, a potassium ionophore, did not significantly affect nicotine uptake, indicating that nicotine uptake is an electroneutral process. For comparison, we assessed the characteristics of nicotine uptake in another lung epithelial cell line NCI-H441 and in non-lung epithelial cell lines HepG2 and MCF-7. Interestingly, these cell lines showed similar characteristics of nicotine uptake with respect to pH dependency and inhibition by various organic cations. The present findings suggest that a similar or the same pH-dependent transport system is involved in nicotine uptake in these cell lines. A novel molecular mechanism of nicotine transport is proposed. Copyright © 2017 Elsevier Inc. All rights reserved.

There are various methods by which people can express subjective evaluations quantitatively. For example, happiness can be measured on a scale from 1 to 10, and has been suggested as a measure of economic policy. However, there is resistance to these types of measurement from economists, who often regard welfare to be a cardinal, unbounded quantity. It is unclear whether there are differences between subjective evaluation reported on ordinal, bounded scales and on cardinal, unbounded scales. To answer this question, we developed functional magnetic resonance imaging experimental tasks for reporting happiness from monetary gain and the perception of visual stimulus. Subjects tended to report higher values when they used ordinal scales instead of cardinal scales. There were differences in neural activation between ordinal and cardinal reporting scales. The posterior parietal area showed greater activation when subjects used an ordinal scale instead of a cardinal scale. Importantly, the striatum exhibited greater activation when asked to report happiness on an ordinal scale than when asked to report on a cardinal scale. The finding that ordinal (bounded) scales are associated with higher reported happiness and greater activation in the reward system shows that overstatement bias in happiness data must be considered.

Neonatal quinpirole (NQ) treatment to rats increases dopamine D2 receptor sensitivity persistent throughout the animal's lifetime. In Experiment 1, we analyzed the role of α7 and α4β2 nicotinic receptors (nAChRs) in nicotine behavioral sensitization and on the brain-derived neurotrophic factor (BDNF) response to nicotine in NQ- and neonatally saline (NS)-treated rats. In Experiment 2, we analyzed changes in α7 and α4β2 nAChR density in the nucleus accumbens (NAcc) and dorsal striatum in NQ and NS animals sensitized to nicotine. Male and female Sprague-Dawley rats were neonatally treated with quinpirole (1mg/kg) or saline from postnatal days (P)1-21. Animals were given ip injections of either saline or nicotine (0.5mg/kg free base) every second day from P33 to P49 and tested on behavioral sensitization. Before each injection, animals were ip administered the α7 nAChR antagonist methyllycaconitine (MLA; 2 or 4mg/kg) or the α4β2 nAChR antagonist dihydro beta erythroidine (DhβE; 1 or 3mg/kg). Results revealed NQ enhanced nicotine sensitization that was blocked by DhβE. MLA blocked the enhanced nicotine sensitization in NQ animals, but did not block nicotine sensitization. NQ enhanced the NAcc BDNF response to nicotine which was blocked by both antagonists. In Experiment 2, NQ enhanced nicotine sensitization and enhanced α4β2, but not α7, nAChR upregulation in the NAcc. These results suggest a relationship between accumbal BDNF and α4β2 nAChRs and their role in the behavioral response to nicotine in the NQ model which has relevance to schizophrenia, a behavioral disorder with high rates of tobacco smoking.

Discriminating nicotine and non-nicotine containing e-liquids using infrared spectroscopy.

Science.gov (United States)

Deconinck, E; Bothy, J L; Barhdadi, S; Courselle, P

2016-02-20

In a few countries, including Belgium, nicotine-containing e-cigarettes and e-liquids are considered medicines, and therefore cannot freely be sold, but should be distributed in a pharmacy. The fact that in the neighbouring countries these products are freely available, poses a problem for custom personnel, the more the nicotine content of the products is not always labelled, especially when they are bought through internet. Therefore there is a need for easy-to-use equipment and methods to perform a first on site screening of intercepted samples, both for border control as to check label compliance of the sample. The use of attenuated total reflectance-infrared spectroscopy (ATR-IR) and near infrared spectroscopy (NIR), combined with chemometrics was evaluated for the discrimination between nicotine containing and non-nicotine containing samples. It could be concluded that both ATR-IR and NIR could be used for the discrimination when combined with the appropriate chemometric techniques. The presented techniques do not need sample preparation and result in models with a minimum of false negative samples. If a large enough training set can be established the interpretation can be fully automated, making the presented approach suitable for on-site screening of e-liquid samples.

The Christian Understanding of Happiness

Directory of Open Access Journals (Sweden)

Andrzej Zwoliński

2016-04-01

Full Text Available The relationship with God allows man to find the sense of life. Christianity is a humanism – it positions man in the very centre of the world according him the highest place – of the being created after God’s image. The revelation of God’s Love endows man with a new way of enriching himself and others. Thus the desire for happiness gains a new perspective of the divine longing for good. Happiness which Christ promises exceeds the limits of our imagination. It is incon­ ceivable and incomprehensible to those living on earth. Heaven is beyond every word, beyond our conception for it bears the meaning which man cannot fully understand. It is the most supreme happiness, absolutely perfect and complete which no one has ever known. A Christian has to achieve in his life something more than the worldly aims. Whoever limits their life to the earth, focuses only on enjoying and using this life to the full; squeezing from it the last drop heedless of the needs of others.

Is it good to make happy people?

Science.gov (United States)

Rachels, Stuart

1998-04-01

Would it be good, other things being equal, for additional people to exist whose lives would be worth living? I examine and reject several arguments for the answer that it would not be good; then I offer opposing arguments that I believe are more successful. Thus, I agree with utilitarians who say that it is better for there to be more happy people. Next I argue for the stronger claim that the happiness of potential people is as important as that of adults. Potential quality of life, then, matters in a host of bioethical issues: abortion, commercial surrogacy, the treatment of defective newborns, and so on. What is the practical upshot of all this? I reject the idea that we must do whatever is necessary to prolong life worth living. But I also reject the view that the side-effects of overpopulation always outweigh the value of realizing potential happiness. So I advocate a middle position, which I do not identify precisely. Even from this middle position, however, potential happiness is more important that is commonly assumed in bioethics.

To quantify changes in neuronal nAChR binding in vivo, quantitative dynamic SPECT studies were performed with 5-[ 123 I]-iodo-A-85380 in baboons pre and post chronic treatment with (-)-nicotine or saline control. Infusion of (-)-nicotine at a dose of 2.0 mg/kg/24h for 14 days resulted in plasma (-)-nicotine levels of 27.3 ng/mL. This is equivalent to that found in an average human smoker (20 cigarettes a day). In the baboon brain the regional distribution of 5-[ 123 I]-iodo-A-85380 was consistent with the known densities of nAChRs (thalamus > frontal cortex > cerebellum). Changes in nAChR binding were estimated from the volume of distribution (V d ) and binding potential (BP) derived from 3-compartment model fits. In the (-)-nicotine treated animal V d was significantly increased in the thalamus (52%) and cerebellum (50%) seven days post cessation of (-)-nicotine treatment, suggesting upregulation of nAChRs. The observed 33% increase in the frontal cortex failed to reach significance. A significant increase in BP was seen in the thalamus. In the saline control animal no changes were observed in V d or BP under any experimental conditions. In this preliminary study, we have demonstrated for the first time in vivo upregulation of neuronal nAChR binding following chronic (-)-nicotine treatment

Withdrawal from nicotine is an important contributor to smoking relapse. Understanding how reward-based decision making is affected by abstinence and by pharmacotherapies such as nicotine replacement therapy and varenicline tartrate may aid cessation treatment. To independently assess the effects of nicotine dependence and stimulation of the nicotinic acetylcholine receptor on the ability to interpret valence information (reward sensitivity) and subsequently alter behavior as reward contingencies change (cognitive flexibility) in a probabilistic reversal learning task. Nicotine-dependent smokers and nonsmokers completed a probabilistic reversal learning task during acquisition of functional magnetic resonance imaging (fMRI) in a 2-drug, double-blind placebo-controlled crossover design conducted from January 21, 2009, to September 29, 2011. Smokers were abstinent from cigarette smoking for 12 hours for all sessions. In a fully Latin square fashion, participants in both groups underwent MRI twice while receiving varenicline and twice while receiving a placebo pill, wearing either a nicotine or a placebo patch. Imaging analysis was performed from June 15, 2015, to August 10, 2016. A well-established computational model captured effects of smoking status and administration of nicotine and varenicline on probabilistic reversal learning choice behavior. Neural effects of smoking status, nicotine, and varenicline were tested for on MRI contrasts that captured reward sensitivity and cognitive flexibility. The study included 24 nicotine-dependent smokers (12 women and 12 men; mean [SD] age, 35.8 [9.9] years) and 20 nonsmokers (10 women and 10 men; mean [SD] age, 30.4 [7.2] years). Computational modeling indicated that abstinent smokers were biased toward response shifting and that their decisions were less sensitive to the available evidence, suggesting increased impulsivity during withdrawal. These behavioral impairments were mitigated with nicotine and varenicline

Central estrogenic pathways protect against the depressant action of acute nicotine on reflex tachycardia in female rats

We have previously shown that acute exposure of male rats to nicotine preferentially attenuates baroreceptor-mediated control of reflex tachycardia in contrast to no effect on reflex bradycardia. Here, we investigated whether female rats are as sensitive as their male counterparts to the baroreflex depressant effect of nicotine and whether this interaction is modulated by estrogen. Baroreflex curves relating reflex chronotropic responses evoked by i.v. doses (1–16 μg/kg) of phenylephrine (PE) or sodium nitroprusside (SNP), were constructed in conscious freely moving proestrus, ovariectomized (OVX), and estrogen (50 μg/kg/day s.c., 5 days)-replaced OVX (OVXE{sub 2}) rats. Slopes of the curves were taken as a measure of baroreflex sensitivity (BRS{sub PE} and BRS{sub SNP}). Nicotine (100 μg/kg i.v.) reduced BRS{sub SNP} in OVX rats but not in proestrus or OVXE{sub 2} rats. The attenuation of reflex tachycardia by nicotine was also evident in diestrus rats, which exhibited plasma estrogen levels similar to those of OVX rats. BRS{sub PE} was not affected by nicotine in all rat preparations. Experiments were then extended to determine whether central estrogenic receptors modulate the nicotine–BRS{sub SNP} interaction. Intracisteral (i.c.) treatment of OVX rats with estrogen sulfate (0.2 μg/rat) abolished the BRS{sub SNP} attenuating effect of i.v. nicotine. This protective effect of estrogen disappeared when OVX rats were pretreated with i.c. ICI 182,780 (50 μg/rat, selective estrogen receptor antagonist). Together, these findings suggest that central neural pools of estrogen receptors underlie the protection offered by E{sub 2} against nicotine-induced baroreceptor dysfunction in female rats. -- Highlights: ► Estrogen protects against the depressant effect of nicotine on reflex tachycardia. ► The baroreflex response and estrogen status affect the nicotine–BRS interaction. ► The protection offered by estrogen is mediated via central estrogen receptors.

Full Text Available Interaction between well-being and happiness has received an increasing interest worldwide due to its positive impact on people’s lives. The aim of this study was to propose a theoretical model to examine the relationships among wellbeing, leisure satisfaction, life satisfaction and happiness. The results from a survey of 1230 respondent in Turkey indicate that there were significant relationships among national well-being, personal well-being, leisure satisfaction, life satisfaction and happiness. The results support the hypothesized relationships, suggesting that well-being as antecedents, directly affecting leisure, life satisfaction and indirectly affecting happiness. Consistent with previous empirical studies, the findings of this study suggest that leisure satisfaction and life satisfaction are the moderators of dimension of happiness, and significantly mediates the effect of national well-being on happiness.

The aim was to examine the in vivo buccal pH-dependent permeability of nicotine in humans and furthermore compare the in vivo permeability of nicotine to previous in vitro permeability data. The buccal permeability of nicotine was examined in a three-way cross-over study in eight healthy non......-smokers using a buccal perfusion cell. The disappearance of nicotine from perfusion solutions with pH 6.0, 7.4, and 8.1 was studied for 3h. The apparent permeability of nicotine (P(app)) was determined at each pH value. Parotid saliva was collected in an attempt to assess systemic levels of nicotine....... The disappearance rate of nicotine increased significantly as the pH increased, which resulted in P(app) values of 0.57+/-0.55 x 10(-4), 2.10+/-0.23 x 10(-4), and 3.96+/-0.54 x 10(-4)cms(-1) (mean+/-S.D.) at pH 6.0, 7.4, and 8.1, respectively.

A novel bioelectronic sniffer for nicotine in the gas phase was developed with enzyme inhibition principle to butyrylcholinesterase activity. The bioelectronic devices for nicotine in the gas and liquid phases were constructed using a Clark-type dissolved oxygen electrode and a membrane immobilized butyrylcholinesterase and choline oxidase. After the assessment of the sensor performances to choline and butyrylcholine as pre-examinations, the characteristics of the biosensor and bio-sniffer for nicotine were evaluated in the liquid and gas phases, respectively. The sensor signal of the bio-devices with 300 micromol l(-1) of butyrylcholine decreased quickly following application of nicotine and reached to the steady-state current, thus relating the concentration of nicotine in the liquid and gas phases. The biosensor was used to measure nicotine solution from 10 to 300 micromol l(-1). In the gas-phase experiment, the current signal of the bio-sniffer was also found to be linearly to the nicotine concentration over the range of 10.0-1000 ppb including 75.0 ppb as threshold limit value (TLV) by American Conference of Governmental Industrial Hygienists (ACGIH).

This work reports a theoretical study of nicotine molecules interacting with single wall carbon nanotubes (SWCNTs) through ab initio calculations within the framework of density functional theory (DFT). Different adsorption sites for nicotine on the surface of pristine and defective (8,0) SWCNTs were analyzed and the total energy curves, as a function of molecular position relative to the SWCNT surface, were evaluated. The nicotine adsorption process is found to be energetically favorable and the molecule-nanotube interaction is intermediated by the tri-coordinated nitrogen atom from the nicotine. It is also predicted the possibility of a chemical bonding between nicotine and SWCNT through the di-coordinated nitrogen.

The efficacy of pharmacotherapy for smoking cessation is well documented. However, due to relapse rates and side effects, hypnotherapy is gaining attention as an alternative treatment option. The aim of this one-center randomized study was to compare the efficacy of hypnotherapy alone, as well as hypnotherapy with nicotine replacement therapy (NRT), to conventional NRT in patients hospitalized with a cardiac or pulmonary illness. We evaluated self-reported and biochemically verified 7-day prevalence smoking abstinence rates at 12 and 26 weeks post-hospitalization. Patients (n=164) were randomized into one of three counseling-based treatment groups: NRT for 30 days (NRT; n=41), a 90-min hypnotherapy session (H; n=39), and NRT with hypnotherapy (HNRT; n=37). Treatment groups were compared to a "self-quit" group of 35 patients who refused intervention. Hypnotherapy patients were more likely than NRT patients to be nonsmokers at 12 weeks (43.9% vs. 28.2%; p=0.14) and 26 weeks after hospitalization (36.6% vs. 18.0%; p=0.06). Smoking abstinence rates in the HNRT group were similar to the H group. There was no difference in smoking abstinence rates at 26 weeks between "self quit" and participants in any of the treatment groups. In multivariable regression analysis adjusting for diagnosis and demographic characteristics, H and HNRT were over three times more likely than NRT participants to abstain at 26-weeks post-discharge (RR=3.6; p=0.03 and RR=3.2; p=0.04, respectively). Hypnotherapy is more effective than NRT in improving smoking abstinence in patients hospitalized for a smoking-related illness, and could be an asset to post-discharge smoking cessation programs.

Stable isotope studies of nicotine kinetics and bioavailability

International Nuclear Information System (INIS)

Benowitz, N.L.; Jacob, P. III; Denaro, C.; Jenkins, R.

1991-01-01

The stable isotope-labeled compound 3',3'-dideuteronicotine was used to investigate the disposition kinetics of nicotine in smokers, the systemic absorption of nicotine from cigarette smoke, and the bioavailability of nicotine ingested as oral capsules. Blood levels of labeled nicotine could be measured for 9 hours after a 30-minute intravenous infusion. Analysis of disposition kinetics in 10 healthy men revealed a multiexponential decline after the end of an infusion, with an elimination half-life averaging 203 minutes. This half-life was longer than that previously reported, indicating the presence of a shallow elimination phase. Plasma clearance averaged 14.6 ml/min/kg. The average intake of nicotine per cigarette was 2.29 mg. A cigarette smoke-monitoring system that directly measured particulate matter in smoke was evaluated in these subjects. Total particulate matter, number of puffs on the cigarette, total puff volume, and time of puffing correlated with the intake of nicotine from smoking. The oral bioavailability of nicotine averaged 44%. This bioavailability is higher than expected based on the systemic clearance of nicotine and suggests that there may be significant extrahepatic metabolism of nicotine

The presence of nicotine and nicotinic acid (NA) in the marine environment has caused great harm to human health and the natural environment. Therefore, there is an urgent need to use efficient and economical methods to remove such pollutants from the environment. In this study, a nicotine and NA-degrading bacterium-strain JQ581-was isolated from sediment from the East China Sea and identified as a member of Pseudomonas putida based on morphology, physio-biochemical characteristics, and 16S rDNA gene analysis. The relationship between growth and nicotine/NA degradation suggested that strain JQ581 was a good candidate for applications in the bioaugmentation treatment of nicotine/NA contamination. The degradation intermediates of nicotine are pseudooxynicotine (PN) and 3-succinoyl-pyridine (SP) based on UV, high performance liquid chromatography, and liquid chromatography-mass spectrometry analyses. However, 6-hydroxy-3-succinoyl-pyridine (HSP) was not detected. NA degradation intermediates were identified as 6-hydroxynicotinic acid (6HNA). The whole genome of strain JQ581 was sequenced and analyzed. Genome sequence analysis revealed that strain JQ581 contained the gene clusters for nicotine and NA degradation. This is the first report where a marine-derived Pseudomonas strain had the ability to degrade nicotine and NA simultaneously.

Inside-out neuropharmacology of nicotinic drugs.

Science.gov (United States)

Henderson, Brandon J; Lester, Henry A

2015-09-01

Upregulation of neuronal nicotinic acetylcholine receptors (AChRs) is a venerable result of chronic exposure to nicotine; but it is one of several consequences of pharmacological chaperoning by nicotine and by some other nicotinic ligands, especially agonists. Nicotinic ligands permeate through cell membranes, bind to immature AChR oligomers, elicit incompletely understood conformational reorganizations, increase the interaction between adjacent AChR subunits, and enhance the maturation process toward stable AChR pentamers. These changes and stabilizations in turn lead to increases in both anterograde and retrograde traffic within the early secretory pathway. In addition to the eventual upregulation of AChRs at the plasma membrane, other effects of pharmacological chaperoning include modifications to endoplasmic reticulum stress and to the unfolded protein response. Because these processes depend on pharmacological chaperoning within intracellular organelles, we group them as "inside-out pharmacology". This term contrasts with the better-known, acute, "outside-in" effects of activating and desensitizing plasma membrane AChRs. We review current knowledge concerning the mechanisms and consequences of inside-out pharmacology.

Female DBA mice were subjected to one of four treatments: ethanol-containing or control diets, nicotine (0.2, 1.0, 5.0 mg/kg/hr) infusion or saline infusion. After removal from the liquid diets or cessation of infusion, the animals were challenged with an acute dose of ethanol or nicotine. Chronic ethanol-fed mice were tolerant to the effects of ethanol on body temperature and open field activity and were cross tolerant to the effects of nicotine on body temperature and heart rate. Nicotine infused animals were tolerant to the effects of nicotine on body temperature and rotarod performance and were cross tolerant to the effects of ethanol on body temperature. Ethanol-induced sleep time was decreased in chronic ethanol- but not chronic nicotine-treated mice. Chronic drug treatment did not alter the elimination rate of either drug. Chronic ethanol treatment did not alter the number or affinity of brain nicotinic receptors whereas chronic nicotine treatment elicited an increase in the number of [3H]-nicotine binding sites. Tolerance and cross tolerance between ethanol and nicotine is discussed in terms of potential effects on desensitization of brain nicotinic receptors.

The concentrated nicotine in e-cigarette refill liquids can be toxic if inadvertently ingested or absorbed through the skin. Reports of poisonings due to accidental ingestion of nicotine on refill liquids are rapidly increasing, while the evaluation of nicotine dermally absorbed still lacks. For that reason we studied transdermal nicotine absorption after the skin contamination with e-liquid. Donor chambers of eight Franz diffusion cells were filled with 1 mL of 0.8 mg/mL nicotine e-liquid for 24 h. The concentration of nicotine in the receiving phase was determined by high-performance liquid chromatography (LOD:0.1 μg/mL). Nicotine was detectable in receiving solution 2 h after the start of exposure and increased progressively. The medium flux calculated was 4.82 ± 1.05 μg/cm(2)/h with a lag time of 3.9 ± 0.1 h. After 24 h, the nicotine concentration in the receiving compartment was 101.02 ± 22.35 μg/cm(2) corresponding to 3.04 mg of absorbed nicotine after contamination of a skin surface of 100 cm(2). Skin contamination with e-liquid can cause nicotine skin absorption: caution must be paid when handling refill e-liquids. Copyright © 2015 Elsevier Inc. All rights reserved.

Several studies have revealed positive associations between religiosity, health and happiness. However, the vast majority of these studies were carried out on native English-speaking participants. The objective of this study was to estimate the relations between religiosity, health and happiness among a sample (N = 372) of Qatari adolescents (M age = 15.2). The students responded to five self-rating scales to assess religiosity, mental health, physical health, happiness and satisfaction with life. Boys obtained a higher mean score on mental health than did their female counterparts. All the correlations between the rating scales were significant and positive. Principal component analysis disclosed one component and labelled 'Religiosity, health and happiness' in both sexes. The multiple stepwise regression indicated that the predictors of religiosity were the self-ratings of satisfaction with life and happiness in boys, whereas the predictors among girls were satisfaction with life and physical health. On the basis of the responses of the present sample, it was concluded that those who consider themselves as religious were more happy, satisfied with their life and healthy. © The Author(s) 2013.

Everyone is interested in the pursuit of happiness, but the real problem for the researchers is how to measure it. Our aim was to deeply investigate happiness measurement through biomedical signals, using psychophysiological methods to objectify the happiness experiences measurements. The classic valence-arousal model of affective states to study happiness has been extensively used in psychophysiology. However, really few studies considered a real combination of these two dimensions and no study further investigated multidimensional models. More, most studies focused mainly on self-report to measure happiness and a deeper psychophysiological investigation on the dimensions of such an experience is still missing. A multidimensional model of happiness is presented and both the dimensions and the measures extracted within each dimension are comprehensively explained. This multidimensional model aims at being a milestone for future systematic study on psychophysiology of happiness and affective states.

Physiologically based pharmacokinetic (PBPK) modeling was applied to investigate the effects of anti-nicotine antibodies on nicotine disposition in the brains of rats and humans. Successful construction of both rat and human models was achieved by fitting model outputs to published nicotine concentration time course data in the blood and in the brain. Key parameters presumed to have the most effect on the ability of these antibodies to prevent nicotine from entering the brain were selected for investigation using the human model. These parameters, which included antibody affinity for nicotine, antibody cross-reactivity with cotinine, and antibody concentration, were broken down into different, clinically-derived in silico treatment levels and fed into the human PBPK model. Model predictions suggested that all three parameters, in addition to smoking status, have a sizable impact on anti-nicotine antibodies' ability to prevent nicotine from entering the brain and that the antibodies elicited by current human vaccines do not have sufficient binding characteristics to reduce brain nicotine concentrations. If the antibody binding characteristics achieved in animal studies can similarly be achieved in human studies, however, nicotine vaccine efficacy in terms of brain nicotine concentration reduction is predicted to meet threshold values for alleviating nicotine dependence. - Highlights: • Modelling of nicotine disposition in the presence of anti-nicotine antibodies • Key vaccine efficacy factors are evaluated in silico in rats and in humans. • Model predicts insufficient antibody binding in past human nicotine vaccines. • Improving immunogenicity and antibody specificity may lead to vaccine success.

Background Recent human studies confirm animal research showing that nicotine enhances reinforcement from rewards unrelated to nicotine. These effects of acute nicotine via tobacco smoking may also occur when consumed from non-tobacco products. Methods We assessed acute effects of nicotine via electronic cigarettes (“e-cigarettes”) on responding reinforced by music, video, or monetary rewards, or for no reward (control). In a fully within-subjects design, adult dependent smokers (N=28) participated in three similar experimental sessions, each following overnight abstinence (verified by CO≤10 ppm). Varying only in e-cigarette condition, sessions involved controlled exposure to a nicotine (labeled “36 mg/ml”) or placebo (“0”) e-cigarette, or no e-cigarette use. A fourth session involved smoking one’s own tobacco cigarette brand after no abstinence, specifically to compare responses under typical nicotine satiation with these acute e-cigarette conditions after abstinence. Results Reinforced responding for video reward, but not the other rewards, was greater due to use of the nicotine versus placebo e-cigarette (i.e., nicotine per se), while no differences were found between the placebo e-cigarette and no e-cigarette conditions (i.e., e-cigarette use per se). For nicotine via tobacco smoking, responding compared to the nicotine e-cigarette was similar for video but greater for music, while both video and music reward were enhanced relative to the non-nicotine conditions (placebo and no e-cigarette). Conclusions Acute nicotine from a non-tobacco product has some reinforcement enhancing effects in humans, in a manner partly consistent with nicotine via tobacco smoking and perhaps contributing to the rising popularity of nicotine e-cigarette use.

Many dilute nectars consumed by bird pollinators contain secondary metabolites, potentially toxic chemicals produced by plants as defences against herbivores. Consequently, nectar-feeding birds are challenged not only by frequent water excess, but also by the toxin content of their diet. High water turnover, however, could be advantageous to nectar consumers by enabling them to excrete secondary metabolites or their transformation products more easily. We investigated how the alkaloid nicotine, naturally present in nectar of Nicotiana species, influences osmoregulation in white-bellied sunbirds Cinnyris talatala and Cape white-eyes Zosterops virens. We also examined the metabolic fate of nicotine in these two species to shed more light on the post-ingestive mechanisms that allow nectar-feeding birds to tolerate nectar nicotine. A high concentration of nicotine (50 µM) decreased cloacal fluid output and increased its osmolality in both species, due to reduced food intake that led to dehydration. White-eyes excreted a higher proportion of the ingested nicotine-containing diet than sunbirds. However, sugar concentration did not affect nicotine detoxification and elimination. Both species metabolised nicotine, excreting very little unchanged nicotine. Cape white-eyes mainly metabolised nicotine through the cotinine metabolic pathway, with norcotinine being the most abundant metabolite in the excreta, while white-bellied sunbirds excreted mainly nornicotine. Both species also utilized phase II conjugation reactions to detoxify nicotine, with Cape white-eyes depending more on the mercapturic acid pathway to detoxify nicotine than white-bellied sunbirds. We found that sunbirds and white-eyes, despite having a similar nicotine tolerance, responded differently and used different nicotine-derived metabolites to excrete nicotine.

Happiness is one of the most fundamental human goals, which has led researchers to examine the source of individual happiness. Happiness has usually been discussed regarding two aspects (a temporary positive emotion and a trait-like long-term sense of being happy) that are interrelated; for example, individuals with a high level of trait-like subjective happiness tend to rate events as more pleasant. In this study, we hypothesized that the interaction between the two aspects of happiness could be explained by the interaction between structure and function in certain brain regions. Thus, we first assessed the association between gray matter density (GMD) of healthy participants and trait-like subjective happiness using voxel-based morphometry (VBM). Further, to assess the association between the GMD and brain function, we conducted functional magnetic resonance imaging (MRI) using the task of positive emotion induction (imagination of several emotional life events). VBM indicated that the subjective happiness was positively correlated with the GMD of the rostral anterior cingulate cortex (rACC). Functional MRI demonstrated that experimentally induced temporal happy feelings were positively correlated with subjective happiness level and rACC activity. The rACC response to positive events was also positively correlated with its GMD. These results provide convergent structural and functional evidence that the rACC is related to happiness and suggest that the interaction between structure and function in the rACC may explain the trait-state interaction in happiness.

Population-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families. In-depth qualitative interviews were conducted with 13 smoker-family pairs, followed by individual interviews with each participant. A total of 39 interviews were conducted in Vietnamese or Chinese, recorded, translated, and transcribed into English for analysis. Four themes were identified: use and understanding of NRT, nonpharmacologic strategies, familial and religious approaches, and willpower. Both smokers and their family members believed strongly in willpower and a sense of personal responsibility as the primary drivers for stopping smoking. Lack of these 2 qualities keeps many Chinese and Vietnamese men from using NRT to quit smoking. Those who do use NRT often use it incorrectly, following their own preferences rather than product instructions. Our findings indicate the importance of culturally appropriate patient education about NRT. It may be necessary to teach smokers and their families at an individual level about NRT as a complementary approach that can strengthen their resolve to quit smoking. At a community level, public health education on the indication and appropriate use of evidence-based smoking cessation resources, such as NRT, would be an important component of effective tobacco control.

Does a Culture of Happiness Increase Rumination Over Failure?

McGuirk, Lucy; Kuppens, Peter; Kingston, Rosemary; Bastian, Brock

2017-07-17

Promoting happiness within society is good for health, but could the overpromotion of happiness have a downside? Across 2 studies, we investigate 2 emotion norms associated with an emphasis on happiness-the importance of (a) seeking positive emotion, and (b) avoiding negative emotion-and whether these norms have implications for how people respond to, and seek to regulate, their negative emotional experiences. In Study 1, we used an experimental design to show that emphasizing the importance of happiness increased rumination in response to failure. In Study 2, we drew on cross-sectional evidence to investigate the other side of this equation, finding that emphasizing the importance of not experiencing negative emotional states (e.g., depression and anxiety) was also associated with increased rumination, and that this had downstream consequences for well-being. Together, the findings suggest that the overpromotion of happiness, and, in turn, the felt social pressure not to experience negative emotional states, has implications for maladaptive responses to negative emotional experiences.

A life-satisfaction-oriented policy would prove welfare-improving, focusing on fair distribution of income and wealth, social goals and institutional goals such as health,...

Menthol Enhances Nicotine Reward-Related Behavior by Potentiating Nicotine-Induced Changes in nAChR Function, nAChR Upregulation, and DA Neuron Excitability.

Understanding why the quit rate among smokers of menthol cigarettes is lower than non-menthol smokers requires identifying the neurons that are altered by nicotine, menthol, and acetylcholine. Dopaminergic (DA) neurons in the ventral tegmental area (VTA) mediate the positive reinforcing effects of nicotine. Using mouse models, we show that menthol enhances nicotine-induced changes in nicotinic acetylcholine receptors (nAChRs) expressed on midbrain DA neurons. Menthol plus nicotine upregulates nAChR number and function on midbrain DA neurons more than nicotine alone. Menthol also enhances nicotine-induced changes in DA neuron excitability. In a conditioned place preference (CPP) assay, we observed that menthol plus nicotine produces greater reward-related behavior than nicotine alone. Our results connect changes in midbrain DA neurons to menthol-induced enhancements of nicotine reward-related behavior and may help explain how smokers of menthol cigarettes exhibit reduced cessation rates.

Opioid Analgesics and Nicotine: More Than Blowing Smoke.

Yoon, Jin H; Lane, Scott D; Weaver, Michael F

2015-09-01

Practitioners are highly likely to encounter patients with concurrent use of nicotine products and opioid analgesics. Smokers present with more severe and extended chronic pain outcomes and have a higher frequency of prescription opioid use. Current tobacco smoking is a strong predictor of risk for nonmedical use of prescription opioids. Opioid and nicotinic-cholinergic neurotransmitter systems interact in important ways to modulate opioid and nicotine effects: dopamine release induced by nicotine is dependent on facilitation by the opioid system, and the nicotinic-acetylcholine system modulates self-administration of several classes of abused drugs-including opioids. Nicotine can serve as a prime for the use of other drugs, which in the case of the opioid system may be bidirectional. Opioids and compounds in tobacco, including nicotine, are metabolized by the cytochrome P450 enzyme system, but the metabolism of opioids and tobacco products can be complicated. Accordingly, drug interactions are possible but not always clear. Because of these issues, asking about nicotine use in patients taking opioids for pain is recommended. When assessing patient tobacco use, practitioners should also obtain information on products other than cigarettes, such as cigars, pipes, smokeless tobacco, and electronic nicotine delivery systems (ENDS, or e-cigarettes). There are multiple forms of behavioral therapy and pharmacotherapy available to assist patients with smoking cessation, and opioid agonist maintenance and pain clinics represent underutilized opportunities for nicotine intervention programs.

Money Buys Happiness When Spending Fits Our Personality.

Matz, Sandra C; Gladstone, Joe J; Stillwell, David

2016-05-01

In contrast to decades of research reporting surprisingly weak relationships between consumption and happiness, recent findings suggest that money can indeed increase happiness if it is spent the "right way" (e.g., on experiences or on other people). Drawing on the concept of psychological fit, we extend this research by arguing that individual differences play a central role in determining the "right" type of spending to increase well-being. In a field study using more than 76,000 bank-transaction records, we found that individuals spend more on products that match their personality, and that people whose purchases better match their personality report higher levels of life satisfaction. This effect of psychological fit on happiness was stronger than the effect of individuals' total income or the effect of their total spending. A follow-up study showed a causal effect: Personality-matched spending increased positive affect. In summary, when spending matches the buyer's personality, it appears that money can indeed buy happiness. © The Author(s) 2016.

Some people call it “motivation”, others “recognition” or “success”. For all, feeling happy at work is an important contributing factor to feeling good about life. How much of it is in our own hands and how much depends on the Organization’s ways of working?   Some time ago, someone came into my office and remarked on some of the books I have on my shelf: “ Two books related to ‘Happiness at Work’ – how come? Why read about that?”- the person asked.  Why indeed? Is being happy even a relevant question in the work context? Recent literature on the subject seems to suggest that happiness at work has a direct impact on motivation and ultimately on overall performance and productivity. Organisations that recognise this also understand the need to look after the well being of their staff and to focus equally on taking into account the interests of individual members as ...

Greatest Happiness Principle in a Complex System Approach

Katalin Martinás

2012-06-01

Full Text Available The principle of greatest happiness was the basis of ethics in Plato’s and Aristotle’s work, it served as the basis of utility principle in economics, and the happiness research has become a hot topic in social sciences in Western countries in particular in economics recently. Nevertheless there is a considerable scientific pessimism over whether it is even possible to affect sustainable increases in happiness.In this paper we outline an economic theory of decision based on the greatest happiness principle (GHP. Modern equilibrium economics is a simple system simplification of the GHP, the complex approach outlines a non-equilibrium economic theory. The comparison of the approaches reveals the fact that the part of the results – laws of modern economics – follow from the simplifications and they are against the economic nature. The most important consequence is that within the free market economy one cannot be sure that the path found by it leads to a beneficial economic system.

Airborne Nicotine, Secondhand Smoke, and Precursors to Adolescent Smoking.

Secondhand smoke (SHS) directly increases exposure to airborne nicotine, tobacco's main psychoactive substance. When exposed to SHS, nonsmokers inhale 60% to 80% of airborne nicotine, absorb concentrations similar to those absorbed by smokers, and display high levels of nicotine biomarkers. Social modeling, or observing other smokers, is a well-established predictor of smoking during adolescence. Observing smokers also leads to increased pharmacological exposure to airborne nicotine via SHS. The objective of this study is to investigate whether greater exposure to airborne nicotine via SHS increases the risk for smoking initiation precursors among never-smoking adolescents. Secondary students ( N = 406; never-smokers: n = 338, 53% girls, mean age = 12.9, SD = 0.4) participated in the AdoQuest II longitudinal cohort. They answered questionnaires about social exposure to smoking (parents, siblings, peers) and known smoking precursors (eg, expected benefits and/or costs, SHS aversion, smoking susceptibility, and nicotine dependence symptoms). Saliva and hair samples were collected to derive biomarkers of cotinine and nicotine. Adolescents wore a passive monitor for 1 week to measure airborne nicotine. Higher airborne nicotine was significantly associated with greater expected benefits ( R 2 = 0.024) and lower expected costs ( R 2 = 0.014). Higher social exposure was significantly associated with more temptation to try smoking ( R 2 = 0.025), lower aversion to SHS ( R 2 = 0.038), and greater smoking susceptibility ( R 2 = 0.071). Greater social exposure was significantly associated with more nicotine dependence symptoms; this relation worsened with higher nicotine exposure (cotinine R 2 = 0.096; airborne nicotine R 2 = 0.088). Airborne nicotine exposure via SHS is a plausible risk factor for smoking initiation during adolescence. Public health implications include limiting airborne nicotine through smoking bans in homes and cars, in addition to stringent restrictions

Nicotine pharmacokinetics and its application to intake from smoking.

Five subjects were given 25 micrograms/kg nicotine intravenously over 1 min, before and after a loading period involving the smoking of six cigarettes. Plasma nicotine concentrations declined in a biphasic manner, the half-lives of the initial and terminal phases averaging 9 min and 133 min respectively. Terminal half-lives before and after the loading period were essentially the same suggesting the absence of saturation kinetics at nicotine concentrations that build up during smoking. The plasma clearance of nicotine and the volume of distribution were very high averaging 915 ml/min and 1731, respectively. Two approaches were used to calculate the nicotine intake from smoking. The average dose of nicotine absorbed from one cigarette was 1.06 mg which was 82% of the standard machine-smoked yield of 1.3 mg. To illustrate their potential use in 'nicotine titration' studies, these approaches were used to compare nicotine intake from smoking a high (2.4 mg) and low (0.6 mg) nicotine cigarette. The dose of nicotine absorbed averaged 1.14 mg and 0.86 mg per cigarette respectively, being 48% and 143% of the machine-smoked yields. PMID:3986082

Neural and Genetic Correlates of the Social Sharing of Happiness

Full Text Available Happiness is regarded as one of the most fundamental human goals. Given recent reports that positive feelings are contagious (e.g., the presence of a happy person enhances others' happiness because of the human ability to empathize (i.e., sharing emotions, empathic ability may be a key factor in increasing one's own subjective level of happiness. Based on previous studies indicating that a single nucleotide polymorphism in the serotonin 2A receptor gene [HTR2A rs6311 guanine (G vs. adenine (A] is associated with sensitivity to emotional stimuli and several mental disorders such as depression, we predicted that the polymorphism might be associated with the effect of sharing happiness. To elucidate the neural and genetic correlates of the effect of sharing happiness, we first performed functional magnetic resonance imaging (fMRI during a “happy feelings” evocation task (emotional event imagination task, during which we manipulated the valence of the imagined event (positive, neutral, or negative, as well as the presence of a friend experiencing a positive-valence event (presence or absence. We recruited young adult women for this fMRI study because empathic ability may be higher in women than in men. Participants felt happier (p < 0.01 and the mentalizing/theory-of-mind network, which spans the medial prefrontal cortex, temporoparietal junction, temporal poles, and precuneus, was significantly more active (p < 0.05 in the presence condition than in the absence condition regardless of event valence. Moreover, participants with the GG (p < 0.01 and AG (p < 0.05 genotypes of HTR2A experienced happier feelings as well as greater activation of a part of the mentalizing/theory-of-mind network (p < 0.05 during empathy for happiness (neutral/presence condition than those with the AA genotype.

Measuring the impact of major life events upon happiness.

Ballas, Dimitris; Dorling, Danny

2007-12-01

In recent years there have been numerous attempts to define and measure happiness in various contexts and pertaining to a wide range of disciplines, ranging from neuroscience and psychology to philosophy, economics and social policy. This article builds on recent work by economists who attempt to estimate happiness regressions using large random samples of individuals in order to calculate monetary 'compensating amounts' for different life 'events'. We estimate happiness regressions using the 'major life event' and 'happiness' data from the British Household Panel Survey. The data and methods used in this article suggest that in contrast to living states such as 'being married', it is more events such as 'starting a new relationship' that have the highest positive effect on happiness. This is closely followed by 'employment-related gains' (in contrast to employment status). Also, women who become pregnant on average report higher than average levels of subjective happiness (in contrast to 'being a parent'). Other events that appear to be associated with happiness according to our analysis include 'personal education-related events' (e.g. starting a new course, graduating from University, passing exams) and 'finance/house related events' (e.g. buying a new house). On the other hand, the event that has the highest negative impact upon happiness according to our analysis is 'the end of my relationship' closely followed by 'death of a parent'. Adverse health events pertaining to the parents of the respondents also have a high negative coefficient and so does an employment-related loss. The analysis presented in this article suggests that what matters the most in people's lives in Britain is to have good dynamic interpersonal relationships and to be respected at work with that respect being constantly renewed. These 'goods' are as much reflected through dynamic events as static situations. Relationships at work appear to be of a similar order of importance to those at

Effect of nicotine on negative affect among more impulsive smokers.

Doran, Neal; McChargue, Dennis; Spring, Bonnie; VanderVeen, Joe; Cook, Jessica Werth; Richmond, Malia

2006-08-01

In the present study, the authors tested the hypothesis that nicotine would provide greater relief from negative affect for more impulsive smokers than for less impulsive smokers. Euthymic adult smokers (N=70) participated in 2 laboratory sessions, during which they underwent a negative mood induction (music + autobiographical memory), then smoked either a nicotinized or de-nicotinized cigarette. Mixed-effects regression yielded a significant Impulsivity x Condition (nicotinized vs. de-nicotinized) x Time interaction. Simple effects analyses showed that heightened impulsivity predicted greater negative affect relief after smoking a nicotinized cigarette but not after smoking a de-nicotinized cigarette. These data suggest that nicotine may be a disproportionately powerful negative reinforcer for highly impulsive smokers, promoting higher levels of nicotine dependence and inhibiting smoking cessation.

Beta3 subunits promote expression and nicotine-induced up-regulation of human nicotinic alpha6* nicotinic acetylcholine receptors expressed in transfected cell lines.

Science.gov (United States)

Tumkosit, Prem; Kuryatov, Alexander; Luo, Jie; Lindstrom, Jon

2006-10-01

Nicotinic acetylcholine receptors (AChRs) containing alpha6 subunits are typically found at aminergic nerve endings where they play important roles in nicotine addiction and Parkinson's disease. alpha6* AChRs usually contain beta3 subunits. beta3 subunits are presumed to assemble only in the accessory subunit position within AChRs where they do not participate in forming acetylcholine binding sites. Assembly of subunits in the accessory position may be a critical final step in assembly of mature AChRs. Human alpha6 AChRs subtypes were permanently transfected into human tsA201 human embryonic kidney (HEK) cell lines. alpha6beta2beta3 and alpha6beta4beta3 cell lines were found to express much larger amounts of AChRs and were more sensitive to nicotine-induced increase in the amount of AChRs than were alpha6beta2 or alpha6beta4 cell lines. The increased sensitivity to nicotine-induced up-regulation was due not to a beta3-induced increase in affinity for nicotine but probably to a direct effect on assembly of AChR subunits. HEK cells express only a small amount of mature alpha6beta2 AChRs, but many of these subunits are on the cell surface. This contrasts with Xenopus laevis oocytes, which express a large amount of incorrectly assembled alpha6beta2 subunits that bind cholinergic ligands but form large amorphous intracellular aggregates. Monoclonal antibodies (mAbs) were made to the alpha6 and beta3 subunits to aid in the characterization of these AChRs. The alpha6 mAbs bind to epitopes C-terminal of the extracellular domain. These data demonstrate that both cell type and the accessory subunit beta3 can play important roles in alpha6* AChR expression, stability, and up-regulation by nicotine.

Three radioligands have been commonly used to label putative nicotinic cholinoceptors in the mammalian central nervous system: the agonists [ 3 H]nicotine and [ 3 H]acetylcholine ([ 3 H]ACh--in the presence of atropine to block muscarinic receptors), and the snake venom extract, [ 125 I]-alpha-bungarotoxin([ 125 I]BTX), which acts as a nicotinic antagonist at the neuromuscular junction. Binding studies employing brain homogenates indicate that the regional distributions of both [ 3 H]nicotine and [ 3 H]ACh differ from that of [ 125 I]BTX. The possible relationship between brain sites bound by [ 3 H]nicotine and [ 3 H]ACh has not been examined directly. The authors have used the technique of autoradiography to produce detailed maps of [ 3 H]nicotine, [ 3 H]ACh, and [ 125 I]BTX labeling; near-adjacent tissue sections were compared at many levels of the rat brain. The maps of high affinity agonist labeling are strikingly concordant, with highest densities in the interpeduncular nucleus, most thalamic nuclei, superior colliculus, medial habenula, presubiculum, cerebral cortex (layers I and III/IV), and the substantia nigra pars compacta/ventral tegmental area. The pattern of [ 125 I]BTX binding is strikingly different, the only notable overlap with agonist binding being the cerebral cortex (layer I) and superior colliculus. [ 125 I]BTX binding is also dense in the inferior colliculus, cerebral cortex (layer VI), hypothalamus, and hippocampus, but is virtually absent in thalamus. Various lines of evidence suggest that the high affinity agonist-binding sites in brain correspond to nicotinic cholinergic receptors similar to those found at autonomic ganglia; BTX-binding sites may also serve as receptors for nicotine and are possibly related to neuromuscular nicotinic cholinoceptors

The aim of the present study was to evaluate factors associated with happiness in a sample of Brazilian older adults. A study was conducted with 263 elderly people in the area of coverage of a family health unit located in the state of São Paulo, Brazil. The Subjective Happiness Scale was used to measure happiness, the final score of which determined one of three outcomes: not happy, intermediate, and happy. Disability, sociodemographic characteristics, and psychological, cognitive, and physical factors were considered for the multinomial logistic regression analysis. Statistically significant differences were found among the three groups regarding satisfaction with life, disability, social phobia, anxiety, depression, and frailty (p≤0.05). In the multinomial regression analysis, being "not happy" was significantly associated with satisfaction with life (RRR: 0.53), depression (RRR: 1.46), social phobia (RRR: 1.24), and age (RRR: 1.06). The present findings indicate that psychological factors and age influence the levels of happiness in older adults living in the community. Furthermore, better screening, diagnosis, and treatment of mental health disorders could increase the feeling of happiness among older adults. Copyright © 2017 Elsevier B.V. All rights reserved.

Regulation of nicotine levels in cigarettes and other tobacco products is now possible with the passage of the Family Smoking Prevention and Tobacco Control Act (FSPTCA) in 2009 giving the U.S. Food and Drug Administration authority to regulate tobacco products, and with Articles 9-11 of the World Health Organization Framework Convention on Tobacco Control.[1-2] Both regulatory approaches allow establishing product standards for tobacco constituents, including nicotine. The FSPTCA does not allow nicotine levels to be decreased to zero, although FDA has the authority to reduce nicotine yields to very low, presumably non-addicting levels. The proposal to reduce levels of nicotine to a level that is non-addicting was originally suggested in 1994.[3] Reduction of nicotine in tobacco products could potentially have a profound impact on reducing tobacco-related morbidity and mortality. To examine this issue, two meetings were convened in the United States with non-tobacco-industry scientists of varied disciplines, tobacco control policy-makers and representatives of government agencies. This article provides an overview of the current science in the area of reduced nicotine content cigarettes and key conclusions and recommendations for research and policy that emerged from the deliberations of the meeting members.

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive…

Nicotine and endogenous opioids: neurochemical and pharmacological evidence.

Although the mesolimbic dopamine hypothesis is the most influential theory of nicotine reward and reinforcement, there has been a consensus that other neurotransmitter systems contribute to the addictive properties of nicotine as well. In this regard, the brain opioidergic system is of interest. Striatum is rich in opioid peptides and opioid receptors, and striatal opioidergic neurons are engaged in a bidirectional communication with midbrain dopaminergic neurons, closely regulating each other's activity. Enkephalins and dynorphins exert opposing actions on dopaminergic neurons, increasing and decreasing dopamine release respectively, and are components of circuits promoting positive or negative motivational and affective states. Moreover, dopamine controls the synthesis of striatal enkephalins and dynorphins. Evidence suggests that opioidergic function is altered after nicotine and endogenous opioids are involved in nicotine's behavioral effects. 1) The synthesis and release of β-endorphin, met-enkephalin and dynorphin in brain, especially nucleus accumbens (NAc), are altered after acute or chronic nicotine treatment and during nicotine withdrawal. 2) Although opioid receptor binding and mRNA do not appear to change in the striatum during nicotine withdrawal, the activity of κ-opioid (KOPr) and δ-opioid (DOPr) receptors is attenuated in NAc. 3) The nicotine withdrawal syndrome reminisces that of opiates, and naloxone precipitates some of its somatic, motivational, and affective signs. 4) Genetic and pharmacological studies indicate that μ-opioid (MOPr) receptors are mainly involved in nicotine reward, while DOPrs contribute to the emotional and KOPrs to the aversive responses of nicotine. 5) Finally, MOPrs and enkephalin, but not β-endorphin or dynorphin, are necessary for the physical manifestations of nicotine withdrawal.

To determine how age and distress are associated in individuals with disabilities, and how happiness and its components (meaning, pleasure, and engagement) mediate or moderate this relationship. These were cross-sectional analyses of survey data from 508 community-dwelling adults with a variety of self-reported health conditions and functional disabilities. Measures included the Orientations to Happiness Questionnaire and items from the Behavior Risk Factor Surveillance System. Greater distress was associated with lower global happiness in both mediation and moderation models. The mediation model showed that middle-aged participants (age: 45-64) scored lowest in global happiness, and the effect of age on distress was partially mediated by happiness. None of the happiness components mediated the relationship of age on distress. The moderation model showed a significant interaction effect for age and global happiness on distress, where younger participants low on happiness were significantly more distressed. Of the three happiness components, only meaning was significantly associated with distress. There was a significant interaction between age and meaning, where participants who were younger and scored low on the meaning scale reported significantly higher distress. Findings from this study lay groundwork for the development of clinical interventions to address distress in individuals with functional disabilities. Middle-aged and younger people with disabilities may be particularly affected by lower levels of happiness and might benefit from psychological interventions that focus on increasing overall well-being and providing meaning and purpose in life.

Full Text Available Present study describes the determination of nicotine in various plant samples with a low content of this compound. Nicotine is found naturally in plants from the Solanaceae family. The plants from Nicotiana genus contain large levels of nicotine. However, only low levels are present in plants from Solanum genus including potato, tomato, eggplant, and from Capsicum genus, which are used as food. Because the levels of nicotine in these materials are in the range of parts per billion, the measurements are difficult and the results are very different from study to study. The present study evaluated the level of nicotine in a number of plants (fruits, roots, leaves, tubers from Solanaceae family (not including Nicotiana genus and from several other vegetables commonly used as food. The analysis consisted of the treatment of plant material with an aqueous solution 5% NaOH at 70°C for 30 min, followed by extraction with TBME containing d3-nicotine as an internal standard. The TBME organic layer was analyzed on a 7890B/7000C GC-MS/MS system with a 30 m × 0.25 mm, 0.25 μm film CAM column. The MS/MS system worked in MRM positive ionization mode monitoring the transition 162 - 84 for nicotine and 165 - 87 for d3-nicotine. Particular attention was given to the preservation of the intact levels of nicotine in the plant material. The plant material was analyzed as is, without drying and with minimal exposure to contaminations. Separately, the moisture of the plant material was measured in order to report the nicotine level on a dry-basis. Levels of nicotine around 180 ng/g dry material were obtained for tomatoes and eggplant (fruit and lower levels were obtained for green pepper and potato. Similar levels to that in the tomato fruit were detected in tomato leaves. Materials from other plant families also showed traces of nicotine. [Beitr. Tabakforsch. Int. 27 (2016 54-59

Happiness has been viewed as a temporary emotional state (e.g., pleasure) and a relatively stable state of being happy (subjective happiness level). As previous studies demonstrated that individuals with high subjective happiness level rated their current affective states more positively when they experience positive events, these two aspects of happiness are interrelated. According to a recent neuroimaging study, the cytosine to thymine single-nucleotide polymorphism of the human cannabinoid receptor 1 gene is associated with sensitivity to positive emotional stimuli. Thus, we hypothesized that our genetic traits, such as the human cannabinoid receptor 1 genotypes, are closely related to the two aspects of happiness. In Experiment 1, 198 healthy volunteers were used to compare the subjective happiness level between cytosine allele carriers and thymine-thymine carriers of the human cannabinoid receptor 1 gene. In Experiment 2, we used positron emission tomography with 20 healthy participants to compare the brain responses to positive emotional stimuli of cytosine allele carriers to that of thymine-thymine carriers. Compared to thymine-thymine carriers, cytosine allele carriers have a higher subjective happiness level. Regression analysis indicated that the cytosine allele is significantly associated with subjective happiness level. The positive mood after watching a positive film was significantly higher for the cytosine allele carriers compared to the thymine-thymine carriers. Positive emotion-related brain region such as the medial prefrontal cortex was significantly activated when the cytosine allele carriers watched the positive film compared to the thymine-thymine carriers. Thus, the human cannabinoid receptor 1 genotypes are closely related to two aspects of happiness. Compared to thymine-thymine carriers, the cytosine allele carriers of the human cannabinoid receptor 1 gene, who are sensitive to positive emotional stimuli, exhibited greater magnitude

Nicotine-selective poly(acrylamide/maleic acid) (AAm/MA) hydrogels prepared by γ-irradiation were used in experiments on swelling, diffusion, and interactions of the pharmaceuticals nicotine, nicotinic acid, nicotinamide, and nikethamide. For AAm/MA hydrogel containing 60 mg maleic acid and irradiated at 5.2 kGy, the studies indicated that swelling increased in the following order; nicotine>nicotinamide>nikethamide>nicotinic acid>water. Diffusions of water and the pharmaceuticals within the hydrogels were found to be non-Fickian in character. AAm/MA hydrogel sorbed only nicotine and did not sorb nicotinamide, nikethamide and nicotinic acid in the binding experiments. S-type adsorption in Giles's classification system was observed. Some binding and thermodynamic parameters for AAm/MA hydrogel-nicotine system were calculated using the Scatchard method. The values of adsorption heat and free energy of this system were found to be negative whereas adsorption entropy was found to be positive. (author)

Recent research has described negative relationship between happiness and habitual smoking among adolescents. No study of this relationship has been conducted among Iranian adolescents. The aim of the present study was to characterize the relationship between happiness and cigarette or hookah smoking among a sample of high school students. A sample of 1,161 10th-grade students in Tabriz (northwest Iran) was selected by multi-stage proportional cluster sampling. Participants completed a self-administered multiple-choice questionnaire including information on cigarette smoking, hookah smoking, happiness score, substance abuse, self-injury, general risk-taking behavior, attitudes towards smoking, socioeconomic information, and demographic characteristics. An ordinal logistic regression model was used for data analysis. It was found that 5.9 and 5.0% of students were regular cigarette smokers and regular hookah smokers, respectively. After controlling for potential confounders, higher happiness scores were found to protect students against more advanced stages of cigarette smoking (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99; p=0.013). However, no significant relationship was found between happiness scores and hookah smoking status (OR, 1.01; 95% CI, 0.97 to 1.02; p=0.523). Happiness scores were associated with less advanced stages of habitual cigarette smoking among high school students. Our findings underscore the necessity of conducting longitudinal or interventional studies aiming to determine the effects of enhancing happiness on preventing the transition through the stages of cigarette and hookah smoking.

Happy Face Superiority Effect in Change Detection Paradigm

Full Text Available The aim of the present study was to investigate which affective component guides cognitive processing of emotional facial expressions. According to the threat hypothesis, processing of angry faces is prioritized by the human cognitive system, because rapid detection of threat has a large adaptive value. The negativity hypothesis presumes that distressing emotional experiences of other people attract attention, regardless of whether they represent danger or not. The emotionality hypothesis proposes that positive emotional facial expressions can capture attention as effective as negative ones, while the happy face superiority hypothesis predicts that happy faces are prioritized. In the present study, which was conducted on 24 participants, change detection paradigm was used, because that procedure enables insight into the later stage of information processing. The results obtained show that happy facial expressions are heavily prioritized by the human cognitive system. In explanation of these results, that clearly support the happy face superiority hypothesis, we propose that angry expressions are initially prioritized by our cognitive system, because we benefit from early detection of potential threat in the environment, but in later cognitive processing, happy expressions are given the priority, because smiling is a valuable mechanism for forming and maintaining cooperative relationships. Besides the theoretical relevance, the present study is also valuable methodologically, because we demonstrated that change detection paradigm can be efficiently used for the research of emotional facial expressions processing.
