Identification and quantitation of 3-hydroxy-N-nitrosopyrrolidine in fried bacon and fried-out fat
No full textThe formation of 3-hydroxy-N-nitrosopyrrolidine from decarboxylation
of 4-hydroxy-N-nitrosoproline was demonstrated in model
heating system designed to simulate the conditions of frying bacon.
The identification of the nitrosamine was achieved by comparison of
its TLC R [subscript f] value, gas chromatographic retention time, and mass
spectral fragmentation pattern with those of the authentic compound.
3-Hydroxy-N-nitrosopyrrolidine was isolated from commercial
fried bacon and fried-out fat. The identification of the compound was
achieved by combined gas chromatography-mass spectrometry after
trimethylsilyl derivatization of the nitrosamine. Additional verification
of identity was obtained from coincident retention time data on a combined
gas chromatography-thermal energy analyzer.
Quantitative determination of 3-hydroxy-N-nitrosopyrrolidine
was accomplished without derivatization and was greatly facilitated
by the use of a thermal energy analyzer. Quantitative analysis by
combined gas chromatography-thermal energy analyzer did not
require as extensive cleanup as was required for identification by
combined gas chromatography-mass spectrometry.
The levels of 3-hydroxy-N-nitrosopyrrolidine occurring in five
samples of fried bacon were 0.5 to 3.9 ppb while the levels in fried-out
fat ranged from 0.3 to 2.2 ppb. These levels are lower than the
concentrations generally reported for nitrosopyrrolidine in fried
bacon.
This study, although the number of samples analyzed was
limited, suggests that low ppb levels of 3-hydroxy-N-nitrosopyrrolidine
appear fairly consistently in fried bacon

No full textRecovery Capital and Symptom Improvement in Gambling Disorder: Correlations with Spirituality and Stressful Life Events in Younger but Not Older Adults
No full textAlthough age-related differences have been reported in gambling disorder, prior studies have not examined how age may influence recovery in gambling disorder. Recovery may be influenced by positive factors (e.g., spirituality and recovery capital) and negative factors (e.g., depression, anxiety, and stressful life events). The current study examined associations between these positive and negative factors and gambling disorder DSM-5 symptom improvement in younger and older adults. Younger (less than 55 years of age; n = 86) and older (55 years or older; n = 54) adults, with lifetime gambling disorder treated currently or within the past 5 years in five treatment centers in Israel were assessed using structured scales on past-year and lifetime DSM-5 gambling disorder, intrinsic spirituality, recovery capital, anxiety, depression and stressful life-events. Among younger adults, recovery capital and intrinsic spirituality were associated with gambling disorder symptom improvement. Among older adults, only recovery capital was associated with gambling disorder symptom improvement. Correlations between recovery capital and spirituality (z = 2.34, p = 0.02) and recovery capital and stressful life events (z = 2.29, p = 0.02) were stronger in younger than in older adults. Recovery capital is an important resource that should be considered across older and younger adults with gambling disorder. Spirituality and stressful life events may operate differently across age groups in gambling disorder. Future studies should investigate whether the findings may extend to other groups and the extent to which promoting recovery capital should be integrated into treatments for gambling disorder
Similar roles for recovery capital but not stress in women and men recovering from gambling disorder
No full textBackground: Understanding gender-related differences is important in recovery processes. Previous studies have investigated gender-related differences in factors associated with gambling disorder (GD), but none to date have considered both positive and negative resources related to recovery. Using a recovery capital (RC) framework that considers multiple resources available during recovery, this study examined gender-related similarities and differences in associations between positive resources (RC, spirituality) and negative experiences and states (stressful life events, depression, and anxiety) and GD symptom improvement. Method: One hundred and forty individuals with lifetime GD (101 men) were assessed using DSM-5 diagnostic criteria for GD (past-year and lifetime prior to past-year), the Brief Assessment of RC, the Intrinsic Spirituality Scale, the Stressful Life-events Scale, the Generalized Anxiety Disorder Scale, and the Patient Health Questionnaire 9 for depression. Multiple linear regression and Bayesian statistical analyses were conducted. Results: RC was positively and significantly associated with GD symptom improvement in women and men. Stressful life events were negatively associated with GD symptom improvement only in men. Conclusions: RC is an important positive resource for men and women recovering from GD and should be considered in treating both women and men. Understanding specific RC factors across gender groups and stressors, particularly in men, may aid in developing improved interventions for G

Associations Between Recovery Capital, Spirituality, and DSM-5 Symptom Improvement in Gambling Disorder
No full textUnderstanding how factors promoting recovery from gambling disorder operate is important in gambling studies and treatment programs. The recovery experience may involve multiple positive resources and may be hindered by negative experiences or states. Most prior studies have focused on the latter, generating a gap in understanding the role for positive psychology measures in recovery from gambling disorder. This study investigated the associations between symptom improvement in gambling disorder and positive resources operationalized as recovery capital (internal and external resources that individuals may draw upon during the recovery process) and intrinsic spirituality. Negative experiences and states, including stressful life events, depression, and anxiety, were also considered. One hundred and 40 individuals (101 men) with a lifetime gambling disorder treated in 5 treatment centers in Israel were assessed on DSM-5 diagnostic criteria for gambling disorder (lifetime and past-year), Brief Assessment of Recovery Capital Scale adapted to gambling disorder, Intrinsic Spirituality Scale, Generalized Anxiety Disorder Scale, Patient Health Questionnaire 9 for depression, and Stressful Life Events Scale. Improvement in gambling disorder was calculated by subtracting the criteria count for the previous year from the lifetime count. Although anxiety, stressful life events, and depression were found to be negatively associated with gambling disorder symptom improvement, only recovery capital and spirituality re-mained significant when all variables were entered together in a multiple regression analysis. These findings highlight the positive role of recovery capital and spirituality in the recovery process and suggest treatment providers should integrate a positive psychology approach in gambling disorder treatment programs
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
