    Notizen: Different isoforms of serotonin subtype 2C receptor (5-HT2CR) with altered G protein-coupling efficacy are generated by RNA editing, which converts genomically encoded adenosine residues into inosines. In combination, editing of five sites all located within the second intracellular loop region of 5-HT2CR mRNA changes the gene-encoded Ile, Asn, and Ile at positions 156, 158, and 160, respectively. We analyzed the G protien-coupling functions of previously unreported editing isoform receptors. An ~13-fold reduction in the agonist potency for G protein-coupling stimulation as well as a significantly reduced basal level activity was observed with the thalamus-specific isoform carrying Ile156, Gly158, and Val160 (5-HT2CR-IGV). In contrast, the agonist was four- to five-fold less potent with 5-HT2CR-MSV and -IDV, detected in the amygdala and choroid plexus, respectively, indicating a dominant role for the amino acid residue at position 158 in receptor functions. We also identified a splicing variant receptor with a truncated C terminus that displayed no ligand binding capacity or G protein-coupling activity. Examination of the alternatively spliced RNA encoding this truncated receptor suggests that editing of this variant RNA occurs after completion of splicing, resulting in complete editing at all five sites.

    Notizen: Abstract – This study involved 354 boys aged 5–6 years and 862 boys aged 12–14 years, attending 40 schools in Riyadh. All children were examined at school by a single dental examiner, using criteria similar to those employed in the survey of children’s dental health in the United Kingdom. The prevalence of dental trauma in 354 Saudi boys aged 5–6 years was 33%. The most common type of dental trauma was fracture of enamel (71%) followed by loss of tooth due to trauma (13%), fracture into enamel and dentine (7%), discolouration (5%), pulp involvement (4%). No relationship between the degree of overjet and the occurrence of dental trauma in the primary dentition was observed. The prevalence of dental trauma in 862 12–14-year-old boys was 34%. The commonest dental trauma was fracture of enamel (74%) followed by fracture into enamel and dentine (15%), fracture into enamel-dentine and pulp (5%), loss of tooth due to trauma (3%), and discolouration (0.4%). A significant relationship (P=0.02) between the increased overjet (≥ 6 mm) and the occurrence of dental trauma in the permanent dentition was reported. The present study found no evidence of dental care provided for traumatised primary incisors in 5–6-year-old boys. The treatment of dental trauma in 12–14-year-old boys was negligible (2.4%). The present Saudi Arabian study showed higher prevalence of dental trauma in 5–6- and 12–14-year-old boys than the reported results of the United Kingdom Children’s Dental Health Survey of the same age groups.

    Notizen: Material and methods: Dental examinations were carried out on 354 boys aged 5–6 years, and 862 boys aged 12–14 years, attending 40 schools in Riyadh. The prevalence of dental erosion was assessed using diagnostic criteria similar to those employed in the 1993 UK National Survey of Child Dental Health. Results: Pronounced dental erosion (into dentine or dentine and pulp) was observed in 34% of 5–6 year olds and 26% of 12–14 year olds. Information on food and drink consumed and dietary habits was obtained by means of a questionnaire. Parents reported that 65% of 5–6 year old boys took a drink to bed. Water was the commonest drink consumed (37%) followed by carbonated soft drinks (21%). One third of parents reported that their son had something to eat in bed or during the night and 60% of this was sweet food or confectionery. Seventy per cent of 12–14 year old boys reported consuming drinks at night; these were mainly water (30%), carbonated soft drinks (27%) and tea or coffee, with sugar (18%). Forty-six per cent of the 12–14 year olds reported that they ate in bed at least once a week and 54% of this was sweet food or confectionery. When the dental examination and questionnaire results were correlated, a statistically significant relationship was found between the number of primary maxillary incisors with pronounced erosion of their palatal surfaces and the consumption of carbonated soft drinks at night (P=0.015). A significant relationship was also found between the number of permanent maxillary incisors with pronounced erosion on their palatal surfaces and the frequency of drinks at night (P=0.020), as well as the duration of drinks retained in the mouth (P=0.038). Conclusion: It is concluded that dental erosion is more common in the primary and permanent dentitions of Saudi Arabian boys compared with results for similar age groups from the United Kingdom.

    Notizen: Marketing practice varies among firms. However, the prescriptive literature emphasises a universal view of practice, a "one-size-fits-all" view. This paper addresses the issue of explaining diversity in competitive space and over time. Diversity in competitive space reflects the existence of different routes to high performance. Diversity over time reflects some combination of change in the individual firm and change in a population of firms. In the former case, diversity is shaped by organisational change; in the latter by the disbandment and founding of firms in the population. Miles and Snow's typology is taken as a main point of departure in the search for explanation, and ecological and evolutionary concepts are also drawn upon. The paper starts by examining the discussion of diversity in the literature of strategic management and organisation theory, and then finds evidence of an emerging interest in diversity in the domain of marketing. Based on a number of cross-sectional and longitudinal case studies, it proceeds to explore diversity in company marketing practice. How such variety evolves at industry level is then addressed. Finally, a view of industries as business systems with complex adaptive mechanisms, enabling both evolutionary and revolutionary changes in marketing practice, is offered.

    Notizen: Abstract PURPOSE: The main impetus for a patient with familial adenomatous polyposis to choose colectomy with ileorectal anastomosis over ileal pouch-anal anastomosis is the better functional result. However, does better functional result necessarily translate into better overall quality of life? Previous studies of other diseases have demonstrated no such correlation. This study was performed to determine whether any relationship exists between functional result and quality of life in patients with familial adenomatous polyposis after ileorectal anastomosis and ileal pouch-anal anastomosis. METHODS: All patients with familial adenomatous polyposis who underwent colectomy with ileorectal anastomosis or proctocolectomy with ileal pouch-anal anastomosis from 1980 to 1998 were studied. Functional data were obtained by questionnaire. Health-related quality of life was assessed by two validated instruments, the SF-36 Physical and Mental Health Summary Scales and the SF-36 Health Survey, which measure physical and mental functioning and eight separate health-quality dimensions, including health perception, physical and social functioning, physical and emotional role limitations, mental health, bodily pain, and energy or fatigue. RESULTS: Data were obtained in 44 of 68 patients, 14 with ileorectal anastomosis and 30 with ileal pouch-anal anastomosis. No differences were demonstrated between the two groups for patient age, mean follow-up time, and mean patient age at operation. Functional results were worse for the ileal pouch-anal anastomosis groupvs. the ileorectal anastomosis group in number of bowel movements per day (7.5vs. 5.2;P〈0.05), leakage (43vs. 0 percent;P〈0.01), pad usage (17vs. 0 percent;P〈0.01), perianal skin problems (33vs. 7 percent;P〈0.01), food avoidance (80vs. 43 percent;P〈0.01), and inability to distinguish gas (37vs. 7 percent;P〈0.01). Results of the health-related quality-of-life surveys, however, demonstrated no difference between the ileal pouch-anal anastomosis and ileorectal anastomosis groups. The Physical and Mental summary scales for the ileal pouchanal anastomosis and ileorectal anastomosis groups were not significantly different (Physical Health Scale, 50.3vs. 50.9; Mental Health Scale, 51.7vs. 49.6), and none of the eight dimensions of the SF-36 health survey demonstrated statistical differences between the ileal pouch-anal anastomosis and ileorectal anastomosis groups. CONCLUSION: Better functional results were not equated with better quality of life in this pilot study. Although patients with the ileorectal anastomosis have better functional results than those withileal pouch-anal anastomosis, the measured health-related quality of life as determined by a validated generic health-related quality-of-life instrument is the same for both groups. These results suggest that all patients with familial adenomatous polyposis might be optimally treated with an ileal pouch-anal anastomosis. More importantly, this study suggests that health-related quality of life should play a greater role in the evaluation of care and treatment in colon rectal surgery.
