Partner support, psychological treatment, and nicotine gum in smoking treatment: an incremental study.

Smokers (N = 99) were randomly assigned to one of three conditions: nicotine gum (NG), nicotine gum plus psychological treatment (NG-PT), and nicotine gum plus psychological treatment and partner support (NG-PT-PS). Data were collected at Weeks 0, 4, 12, 26, and 52 from study start. Contrary to expectations, NG-PT-PS and NG-PT failed to increase abstinence rates. Subjects who were closer to their support partners had significantly lower abstinence rates with NG-PT-PS than with the other conditions, although not significantly at Weeks 26 and 52. Treatments without partner participation (NG-PT and NG) were significantly more effective for subjects who had an extremely close support partner outside the treatment setting than for those who did not at all weeks. The role of social support in smoking treatment is discussed.

Partner interaction and smoking cessation: a pilot study.

This was an exploratory study of precessation interaction between 21 smokers and their partners enrolled in a partner support smoking treatment program. The aim was to identify the partner interactions and proposed quitting strategies that were associated with cessation. Significant results (p less than .05) and trends (p less than .10) were reported. Both smoker and partner interactions predicted cessation. Failure to quit was predicted by smokers' negative behavior (prosmoking statements, interrupting the partner, and criticism/rejection of help) and by partners' suggestion to disengage from the quitting process. Partner's suggestion to disengage may be a reaction to the smokers' negative behavior because it was positively correlated with it. Successful quitters and their partners proposed more self-help strategies than did nonquitters and their partners. Nonquitters proposed more cooperative strategies than did successful quitters. Thus, suggesting strategies that encourage autonomy and self-mastery, rather than dependence on another person, may lead to more positive outcomes.

Osmolarity effects on observed insect cell size after baculovirus infection are avoided using growth medium for sample dilution.

Rates of cell size increase are an important measure of success during the baculovirus infection process. Batch and fed batch cultures sustain large fluctuations in osmolarity that can affect the measured cell volume if this parameter is not considered during the sizing protocol. Where osmolarity differences between the sizing diluent and the culture broth exist, biased measurements of size are obtained as a result of the cell osmometer response. Spodoptera frugiperda (Sf9) cells are highly sensitive to volume change when subjected to a change in osmolarity. Use of the modified protocol with culture supernatants for sample dilution prior to sizing removed the observed error during measurement.
