In this paper we describe the analysis, planning, design, development, implementation and evaluation of a new online Graduate Certificate in Genomic Counselling and Variant Interpretation (GCGCVI) at The University of British Columbia (UBC). Genetic counselling is now a prerequisite for diagnostic genomic testing in many countries, demanding that genetic counselling practitioners have up-to-the-moment genomic counselling skills and knowledge. Current practitioners reported a desire for more training in this rapidly developing field: our international survey revealed substantial interest in online continuing education addressing themes such as testing and clinical bioinformatics, applied variant interpretation, evidence-based genomic counselling, and other emerging genomic topics.

Cigarette on-pack messages are one of the principal vehicles for informing smokers about the risks of smoking and research has highlighted their role as a valid health communication tool. Furthermore, they have the potential to disrupt the powerful cigarette brand imagery associated with tobacco packaging. Responding to concerns within Europe that the old style on-pack messages were ineffective and the introduction of new tobacco product legislation across Europe (EU Directive 2001/37/EC), this study was conducted to explore European smokers' response to the changes.

Cell ploidy in the ovarian follicle and corpus luteum was investigated by DNA in situ hybridization to a reiterated, chromosome 3 transgene in mice that were hemizygous for the transgene. This approach was first validated by analysis of mouse kidney, pancreas and liver control tissues, which contain different frequencies of polyploid nuclei. Polyploid nuclei (with multiple hybridization signals) were seen in histological sections of both ovarian follicles and corpora lutea.

Ten years ago research showed that pro-smoking images were prevalent in British youth magazines, whereas there was little coverage of smoking and health. Since then there has been a great expansion in the number of youth magazines, and particularly those aimed at young men. Titles such as FHM and Loaded, which did not exist at the time of the previous research, are now market leaders.

Tobacco-industry marketing has played a central part in the global spread of tobacco use and addiction. Although the absolute size of the tobacco market has dwindled, the industry is still immensely successful, largely due to sophisticated and manipulative marketing strategies. The UK tobacco industry identifies target groups and builds enduring relationships based on careful brand management.

Over the last decade Britain has observed a trend towards the re-regulation of 'prescription only medicines' in favour of pharmacy status drugs. This move towards self-treatment to reduce pressures on general practitioner drug budgets and workloads has focused attention on the need for community pharmacists to extend their patient education and screening roles. In response to these changes, this study was conducted to explore: the type of over-the-counter (OTC) medicine being misused in Scotland; pharmacists' professional attitudes and management of OTC misuse; and the training and support needs of pharmacists.

DNA uptake by naturally competent bacteria provides cells with both genetic information and nucleotides. In Haemophilus influenzae, competence development requires both cAMP and an unidentified signal arising under starvation conditions. To investigate this signal, competence induction was examined in media supplemented with nucleic acid precursors.

Objectives: To examine young people's awareness of and involvement with tobacco marketing and to determine the association, if any, between this and their smoking behaviour.

Design: Cross sectional, quantitative survey, part interview and part self completion, administered in respondents' homes.

Setting: North east England.

Development of competence for DNA uptake by the bacterium Haemophilus influenzae is tightly regulated, and expression of the cell's complement of competence genes is absolutely dependent on the cAMP-CRP complex. A second regulator of competence may maximize competence under starvation conditions. Several investigators have recently identified a consensus sequence (competence regulatory element, CRE) in the promoter regions of some competence genes and have proposed that this may be a binding site for Sxy (TfoX), a putative positive regulator of competence.

Changes in intracellular 3',5' cyclic AMP (cAMP) concentration regulate the development of natural competence in Haemophilus influenzae. In Escherichia coli, cAMP levels are modulated by a cAMP phosphodiesterase encoded by the cpdA gene. We have used several approaches to demonstrate that the homologous icc gene of H.

Changes in intracellular cAMP concentration play important roles in Haemophilus influenzae, regulating both sugar utilization and competence for natural transformation. In enteric bacteria, cAMP levels are controlled by the phosphoenolpyruvate:glycose phosphotransferase system (PTS) in response to changes in availability of the preferred sugars it transports. We have demonstrated the existence of a simple PTS in H.
