Selected AbstractsEffect of isometric exercise and body scanning on cigarette cravings and withdrawal symptomsADDICTION, Issue 7 2009Michael Ussher ABSTRACT Aims To examine the acute effects of a guided relaxation routine (body scan) and isometric exercise on desire to smoke and tobacco withdrawal symptoms. Design Experimental comparison of three conditions. Participants Forty-eight individuals reporting smoking ,10 cigarettes daily. Intervention Random assignment to one of three interventions delivered via a 10-minute audio: isometric exercise (IE, n = 14), body scanning (BS, n = 18) or a reading about natural history (control group, n = 16). Interventions were delivered twice on the same day: in the laboratory, then in their ,normal' environment. Measurements Desire to smoke (primary outcome) and withdrawal symptoms were rated at pre-intervention and up to 30 minutes post-intervention. Findings Controlling for baseline scores, post-intervention desire to smoke and withdrawal symptoms were significantly lower for IE and BS groups, compared with the controls, in both environments. There were no significant differences for IE versus BS. For desire to smoke, controlling for baseline values, ratings in the laboratory were significantly lower for IE and BS versus the control up to 30 minutes post-intervention. In the normal environment, these ratings were significantly lower only up to 5 minutes post-intervention. Conclusions Brief IE and BS interventions are effective for reducing desire to smoke and withdrawal symptoms in temporarily abstaining smokers. These interventions were found to be more effective in the laboratory than in the smoker's normal environment, but this may be an artefact of there not being a sufficient ,wash-out' period between interventions. These techniques may be beneficial for managing desire to smoke and tobacco withdrawal. [source] Pharmacological doses of dietary curcumin increase colon epithelial cell proliferation in vivo in ratsPHYTOTHERAPY RESEARCH, Issue 10 2007Sylvia Jeewon Kim Abstract Although curcumin has preventive actions in animal models of colon cancer, whether the mechanism of action is through anti-proliferation in normal environment is not clearly understood. Here, we studied the effects of chemopreventive doses of curcumin on the proliferation rate of colon epithelial cells (CEC), using a recently developed stable isotope , mass spectrometric method for measuring DNA synthesis rate. Adult male F344 rats were given diets containing 0, 2 and 4% curcumin for 5 weeks. 4% 2H2O was given in drinking water to label DNA, after a priming bolus, for 4 days prior to sacrifice. The isotopic enrichment of the deoxyribose moiety of deoxyadenosine from DNA was measured by gas chromatography , mass spectrometry. Cell cycle analysis was performed after propidium iodide staining of CECs. Curcumin administration did not reduce but instead resulted in dose-dependent increases in CEC proliferation rate (p < 0.05) for 2% and 4% curcumin vs 0%). The length of the colon crypts and the fraction of cells in S-phase were also increased in the 2% and 4% curcumin groups (p < 0.05). Thus, pharmacological doses of curcumin increase CEC proliferation rate and pool size in normal rats. Reduction of CEC proliferation therefore cannot explain the proposed chemopreventive actions of curcumin in colon cancer. Copyright © 2007 John Wiley & Sons, Ltd. [source] ,Time Out' for Women: Innovation in Scotland in a Context of ChangeTHE HOWARD JOURNAL OF CRIMINAL JUSTICE, Issue 4 2008MARGARET MALLOCH Abstract: The 218 Centre was set up following consistent concerns about the increasing number of women in prison in Scotland and the high-level needs of many of these women. It is an innovative and high-profile attempt to develop appropriate responses to women in the criminal justice system. It offers women an opportunity for ,time out' of their normal environment without resorting to ,time in' custody, providing both residential and community-based services. This article outlines some of the issues and challenges which characterised the early development and operation of the 218 Centre. It illustrates the ways in which some of the issues that arose during the evaluation resonate with current and ongoing debates within criminology, and draws attention to the difficulties in using the criminal justice system to address other issues.
