The Road to Recovery: A New Approach to Tackling Scotland's Drug Problem

The Scottish National Drugs Strategy requires the 22 regional Drug Action Teams to prepare and submit to the Scottish Executive annual action plans for tackling drug misuse in their areas. These plans should address national and local priorities, including their contribution to the achievement of national targets. These comprise three parts: Part A provides an overview of the DAT structures and working; Part B provides detailed information on current local services and Part C reports plans for 2003/04.This resource was contributed by The National Documentation Centre on Drug Use.

Multimedia materials for education, training, and advocacy in international health: experiences with the Schistosomiasis Control Initiative CD-ROM

We describe an innovative use of multimedia materials to support training and advocacy within a schistosomiasis control programme. The Schistosomiasis Control Initiative (SCI) at Imperial College London works with selected sub-Saharan African countries to develop schistosomiasis control programmes. Two elements of the SCI programme were supported by multimedia materials developed at the Wellcome Trust in collaboration with the SCI: (1) training of programme managers, district health officers, and those delivering practical elements of the programme; and (2) advocacy targeted at decision-makers and donors. Evaluation of the materials revealed high reported ratings for both user satisfaction and impact from use of the product. From this experience we draw out several general messages about development of multimedia materials and how these will play a growing future role in promoting training within international health.

Quality assurance in road traffic analyses in Switzerland.

Swiss laboratories performing toxicological road traffic analyses have been authorized for many years by the Swiss Federal Roads Office (FEDRO). In 2003 FEDRO signed a contract with the Swiss Society of Legal Medicine (SSLM) to organize the complete quality management concerning road traffic analyses. For this purpose a multidisciplinary working group was established under the name of "road traffic commission (RTC)". RTC has to organize external quality control, to interpret the results of these controls, to perform audits in the laboratories and to report all results to FEDRO. Furthermore the working group can be mandated for special tasks by FEDRO. As an independent organization the Swiss Center for Quality Control (CSCQ) in Geneva manages the external quality controls in the laboratory over the past years. All tested drugs and psychoactive substances are listed in a federal instruction. The so-called 'zero tolerance substances' (THC, morphine, cocaine, amphetamine, methamphetamine, MDMA and MDEA) and their metabolites have to be tested once a year, all other substances (benzodiazepines, zolpidem, phenobarbital, etc.) periodically. Results over the last years show that all laboratories are generally within the confidence interval of +/-30% of the mean value. In cases of non-conformities measures have to be taken immediately and reported to the working group. External audits are performed triennially but accredited laboratories can combine this audit with the approval of the Swiss Accreditation Service (SAS). During the audits a special checklist filled in by the laboratory director is assessed. Non-conformities have to be corrected. During the process of establishing a new legislation, RTC had an opportunity of advising FEDRO. In collaboration with FEDRO, RTC and hence SSLM can work actively on improving of quality assurance in road traffic toxicological analyses, and has an opportunity to bring its professional requests to the federal authorities.

The high road and the low road: trafficking choices in plants.

Polar transport of the signaling molecule auxin is critical for plant development and depends on both the polar distribution of auxin efflux carriers, which pump auxin out of the cell and the alignment of these polarized cells. Two papers in this issue of Cell (Michniewicz et al., 2007; Jaillais et al., 2007) address how polar transport of these carriers occurs and describe the endosomal pathways involved.

Determinants of the educational use of digital learning materials: The mediating role of self-efficacy, perceived norm and attitude

Initiatives to stimulate the development and propagation of open educational resources (OER) need a sufficiently large community that can be mobilized to participate in this endeavour. Failure to achieve this could lead to underuse of OER. In the context of the Wikiwijs initiative a large scale survey was undertaken amongst primary and secondary school teachers to explore possible determinants of the educational use of digital learning materials (DLMs). Basing on the Integrative Model of Behaviour Prediction it was conjectured that self-efficacy, attitude and perceived norm would take a central role in explaining the intention to use DLMs. Several other predictors were added to the model as well whose effects were hypothesized to be mediated by the three central variables.All conjectured relationships were found using path analysis on survey data from 1484 teachers. Intention to DLMs was most strongly determined by self-efficacy, followed by attitude. ICT proficiency was in its turn the strongest predictor of self-efficacy. Perceived norm played only a limited role in the intention to use DLMs. Concluding, it seems paramount for the success of projects such as Wikiwijs to train teachers in the use of digital learning materials and ICT (e.g. the digital blackboard) and to impact on their attitude.

Síntesi de nous compostos tipus catecol amb aplicació en materials funcionals

En el nostre grup d’investigació i en col·laboració amb el grup d’investigació del doctor Daniel Ruiz-Molina del Centre d’investigació en Nanociència i Nanotecnologia (CIN2) d’aquest campus universitari, hem iniciat un projecte que es planteja aconseguir biomimetitzar certes proteïnes adhesives de mol·luscs, en que la seva adherència es deu a la presència de la funcionalitat catecol. Aprofitant aquesta propietat adhesiva dels catecols, l’objectiu és poder desenvolupar nous materials per a recobriments hidro- i oleofòbics, i nous materials adhesius sent necessari el desenvolupament de protocols sintètics per a l’obtenció de compostos tipus catecol convenientment substituïts. En el present treball de recerca s’ha aconseguit la síntesi del nou catecol 10, que presenta en la seva estructura una cadena alquílica parcialment fluorada amb la finalitat de fer-ne recobriments hidro- i oleofòbics, i l’optimització i escalat del catecol 2, que presenta una cadena alquílica, amb la finalitat de fer-ne recobriments hidrofòbics. També s’ha explorat en la síntesi de catecols amb una funcionalitat tiol amb la finalitat de poder desenvolupar superfícies o nanopartícules d’or adhesives. Partint del producte comercial 17, s’ha aconseguit obtenir 10 en tres etapes sintètiques i un rendiment global del 57% i 2 en dues etapes sintètiques i un rendiment global del 63% a escala multigram, millorant la metodologia sintètica existent que consistia en quatre etapes sintètiques i un 48% de rendiment global.

Be fit or be sick: peroxisome proliferator-activated receptors are down the road.

Investigating metabolism by unveiling the functions of the nuclear receptors peroxisome proliferator-activated receptors (PPARs) in the numerous intricate pathways ensuring energy homeostasis and fitness has been extremely rewarding. Major lines of research were initially determined by the first-characterized crucial roles of PPARalpha in fatty oxidation and of PPARgamma in adipocyte differentiation and lipid storage. Today, the molecular bases of the functional links between glucose, lipid, and protein metabolism, under the important but nonexclusive control of PPARalpha and PPARgamma, are starting to be uncovered. In addition, in the last couple of years evidence has been provided for an important role of PPARbeta (delta) in lipid metabolism. Inevitably, such actors of metabolic homeostasis are implicated in the physiopathology of complex metabolic disorders, such as those constituting the metabolic syndrome, resulting in atherosclerosis and cardiovascular diseases. This review presents a summary of the recent findings on their dual involvement in health and disease.

MR and CT imaging of pulmonary valved conduits in children and adolescents: normal appearance and complications.

BACKGROUND: The Contegra® is a conduit made from the bovine jugular vein and then interposed between the right ventricle and the pulmonary artery. It is used for cardiac malformations in the reconstruction of right ventricular outflow tract. OBJECTIVE: To describe both normal and pathological appearances of the Contegra® in radiological imaging, to describe imaging of complications and to define the role of CT and MRI in postoperative follow-up. MATERIALS AND METHODS: Forty-three examinations of 24 patients (17 boys and 7 girls; mean age: 10.8 years old) with Contegra® conduits were reviewed. Anatomical description and measurements of the conduits were performed. Pathological items examined included stenosis, dilatation, plicature or twist, thrombus or vegetations, calcifications and valvular regurgitation. Findings were correlated to the echographic gradient through the conduit when available. RESULTS: CT and MR work-up showed Contegra® stenosis (n = 12), dilatation (n = 9) and plicature or twist (n = 7). CT displayed thrombus or vegetations in the Contegra® in three clinically infected patients. Calcifications of the conduit were present at CT in 12 patients and valvular regurgitation in three patients. The comparison between CT and/or MR results showed a good correlation between the echographic gradient and the presence of stenosis in the Contegra®. CONCLUSION: CT and MR bring additional information about permeability and postoperative anatomy especially when echocardiography is inconclusive. Both techniques depict the normal appearance of the conduit, and allow comparison and precise evaluation of changes in the postoperative follow-up.
