    Notizen: One challenge in the analysis of event-related potentials (ERPs) is to identify task-related differences in scalp topography. The multivariate Partial Least Squares (PLS) analysis was used to identify the spatiotemporal distribution of ERP differences related to experimental manipulations. Two simulations included latency shifts and amplitude changes at peaks with temporal overlap. PLS identified effects only at modeled timepoints and electrodes. In contrast, principal components analysis identified differences at most timepoints. We also demonstrated that PLS identified combinations of waveform differences, not isolated sources. ERP components in an auditory oddball task were also assessed with PLS. The primary distinction was between ERPs on hit and correct rejection trials, expressed at multiple timepoints and electrodes. PLS provides a mechanism to describe experimental differences in ERP waveforms, simultaneously across the head.

    Notizen: Past research has demonstrated an age-related increase in the Stroop effect. Some theorists have suggested that this increase results from a decline in the ability to inhibit word information on incongruent trials, whereas others have suggested that the decline reflects general slowing. These two hypotheses were evaluated using event-related brain potentials (ERPs) measured while younger and older adults performed the Stroop task. As expected, the Stroop effect was greater for older than younger adults. The ERP data revealed a selective age-related attenuation of two modulations reflecting the inhibition of word information on incongruent trials. Latency of the P3 wave did not increase to a greater extend for older than younger adults from the congruent to incongruent trials as expected based on the general slowing hypothesis. Taken together, these findings support the inhibitory deficit hypothesis by demonstrating an age-related decline in a conceptual level inhibitory process that supports the suppression of word information in the Stroop task.

    Notizen: Abstract Spindle microtubules interact with mitotic chromosomes, binding to their kinetochores to generate forces that are important for accurate chromosome segregation. Motor enzymes localized both at kinetochores and spindle poles help to form the biologically significant attachments between spindle fibers and their cargo, but microtubule-associated proteins without motor activity contribute to these junctions in important ways. This review examines the molecules necessary for chromosome-microtubule interaction in a range of well-studied organisms, using biological diversity to identify the factors that are essential for organized chromosome movement. We conclude that microtubule dynamics and the proteins that control them are likely to be more important for mitosis than the current enthusiasm for motor enzymes would suggest.

    Notizen: Aims.  This paper presents a comprehensive systematic review of literature carried out to identify studies of interventions to improve uptake, adherence and professional compliance in cardiac rehabilitation.Background.  Guidelines recommend that cardiac rehabilitation should be offered to patients following acute myocardial infarction and revascularization. Uptake and adherence are low, particularly in women, older people, and socially deprived and ethnic minority patients. Although patient, service and professional barriers to rehabilitation uptake have been described, no attempt has been made to evaluate systematically interventions aimed at improving uptake and adherence in cardiac rehabilitation.Methods.  A comprehensive search strategy identified studies of cardiac rehabilitation, using the terms uptake, adherence and compliance. The search included grey literature, hand searching of specialist journals and conference abstracts. No language restriction was applied. Studies were summarized in three qualitative overviews and assessed by quality of evidence.Results.  From 3261 publications identified, 957 were acquired on the basis of title or abstract. Few studies were of sufficient quality to make specific recommendations. Six, 12 and five studies, respectively, provided adequate information on methods to improve uptake, adherence or professional compliance. A minority of studies were randomized controlled trials. Studies of motivational and self-management strategies and use of lay volunteers showed some promise in improving rehabilitation uptake or lifestyle change. Nurse-led coordination of care after hospital discharge may have a role in improving rehabilitation uptake. Limited information was provided on resource implications, and there was a lack of studies with under-represented groups. The literature contained numerous suggested interventions which merit evaluation in appropriately designed studies.Conclusions.  Little research has been reported evaluating interventions to improve uptake, adherence and professional compliance in cardiac rehabilitation. A wide range of possible interventions was identified and further evaluations of methods are indicated.

    Notizen: Objectives. Several countries have followed the US example in publishing national guidelines on smoking cessation interventions. Gauging responses to these guidelines can provide important lessons for future implementation and revision internationally. This study sought to assess General Practitioners' (GPs') views on recently published English smoking cessation guidelines that form the foundation of the UK National Health Service's smoking cessation strategy. Design. Postal survey in which GPs were asked to judge the appropriateness, effectiveness and practicability of key recommendations for primary care in recent national smoking cessation guidelines. Setting. General practice, England and Wales. Subjects. Random national sample of GPs; 236 GPs completed the questionnaire; effective response rate: 62%. Results. Only 16% of GPs accepted that all the recommendations in the guidelines were appropriate; 43% accepted that it was appropriate to check the smoking status of known smokers when they visit the surgery and only 30% thought it was practicable to advise smokers to stop at every opportunity. However, 77% of GPs thought that they should provide assistance for smokers wanting to stop; 74% believed that they should refer smokers to specialist services if appropriate and a similar proportion (77%) believed that it was appropriate to recommend nicotine replacement therapy. Conclusions. There was greater acceptance by GPs that they should assist smokers wanting to stop than that they should routinely monitor smoking status and give opportunistic advice to patients to stop. Given that opportunistic advice is a cornerstone of the national guidelines there is a need to find ways of reconciling what is being recommended and what GPs feel is appropriate.
