RESUMO
Televised alcohol advertisements in the United Kingdom must abide by the Broadcast Committee of Advertising Practice Code, which provides guidelines concerning advertisements not implying, condoning or encouraging immoderate, irresponsible or antisocial drinking. Previously, 75 per cent of 373 general public respondents were shown one of seven advertisements rated a breach of at least one guideline. This study assessed whether experts in marketing (n = 25) and alcohol treatment/public health (n = 25) perceived the same seven television alcohol advertisements as complying with the Broadcast Committee of Advertising Practice Code. Overall, 83 per cent of advertisements were rated as breaching at least one guideline. This provides further proof that self-regulatory alcohol guidelines are not fit for purpose.

Neurotoxicity is linked with high-dose manganese inhalation. There are few biomarkers that correlate with manganese exposure. Blood manganese concentrations depend upon the magnitude and duration of the manganese exposure and inconsistently reflect manganese exposure concentrations. The objective of this study was to search for novel biomarkers of manganese exposure in the urine and blood obtained from rhesus monkeys following subchronic manganese sulfate (MnSO(4)) inhalation. Liquid chromatography-mass spectrometry was used to identify putative biomarkers. Juvenile rhesus monkeys were exposed 5 days/week to airborne MnSO(4) at 0, 0.06, 0.3, or 1.5 mg Mn/m(3) for 65 exposure days or 1.5 mg Mn/m(3) for 15 or 33 days. Monkeys exposed to MnSO(4) at >or= 0.06 mg Mn/m(3) developed increased brain manganese concentrations. A total of 1097 parent peaks were identified in whole blood and 2462 peaks in urine. Principal component analysis was performed on a subset of 113 peaks that were found to be significantly changed following subchronic manganese exposure. Using the Nearest Centroid analysis, the subset of 113 significantly perturbed components predicted globus pallidus manganese concentrations with 72.9% accuracy for all subchronically exposed monkeys. Using the five confirmed components, the prediction rate for high brain manganese levels remained > 70%. Three of the five identified components, guanosine, disaccharides, and phenylpyruvate, were significantly correlated with brain manganese levels. In all, 27 metabolites with statistically significant expression differences were structurally confirmed by MS-MS methods. Biochemical changes identified in manganese-exposed monkeys included endpoints relate to oxidative stress (e.g., oxidized glutathione) and neurotransmission (aminobutyrate, glutamine, phenylalanine).

We examined the extent to which priming the liver with a pulse of Humulin or the insulin analog hexyl-insulin monoconjugate 2 (HIM2) reduces postprandial hyperglycemia. Somatostatin (0.5 microg.kg(-1).min(-1)) was given with basal intraportal insulin and glucagon for 4.5 h into three groups of 42-h-fasted conscious dogs. From 0-5 min, group 1 (BI, n = 6) received saline, group 2 (HI, n = 6) received a Humulin pulse (10 mU.kg(-1).min(-1)), and group 3 (HIM2, n = 6) received a HIM2 pulse (10 mU.kg(-1).min(-1)). Duodenal glucose was infused (5.0 mg.kg(-1).min(-1)) from 15 to 270 min. Arterial insulin in BI remained basal (6 +/- 1 microU/ml) and peaked at 52 +/- 15 (HI) and 164 +/- 44 microU/ml (HIM2) and returned to baseline by 30 and 60 min, respectively. Arterial plasma glucose plateaued at 265 +/- 20, 214 +/- 15, and 193 +/- 14 mg/dl in BI, HI, and HIM2. Glucose absorption was similar in all groups. Significant net hepatic glucose uptake occurred at 85, 55, and 25 min in BI, HI, and HIM2, respectively. Nonhepatic glucose clearance at 270 min differed among groups (BI, HI, HIM2): 0.62 +/- 0.11, 0.76 +/- 0.26, and 1.61 +/- 0.29 ml.kg(-1).min(-1) (P < 0.05). A brief (5-min) insulin pulse improved postprandial glycemia, stimulating hepatic glucose uptake and prolonging enhancement of nonhepatic glucose clearance. HIM2 was more effective than Humulin, perhaps because its lowered clearance caused higher levels at the liver and periphery and its biological activity was not reduced proportionally to its decreased clearance.

BACKGROUND: The Salford Health Investment for Tomorrow and the Local Improvement Finance Trust proposals for the comprehensive redevelopment of Salford Royal Hospital and the provision of four integrated primary health and social centres in the City of Salford are a response to the challenge of the NHS Plan to modernize delivery and service provision. The scale of the proposed developments will have a major effect on the quality of life in Salford. This health impact assessment was undertaken to determine how these proposals could be amended to ensure that the impacts are optimised so that potential benefits to Salford's communities are realised to maximise their health and wellbeing. METHOD: This involved a comprehensive prospective health impact assessment and a series of interviews with key stakeholders, community organisations, and local people to identify and prioritize potential positive and negative impacts of the proposals. RESULTS AND CONCLUSIONS: The assessment pointed to a wide range of positive and negative impacts that provided the basis of a set of recommendations, which were linked directly to the themes of the Salford Community Plan. These related to setting employment, education, and training opportunities to maximise health and wellbeing and improve quality of life for all communities in Salford within the framework of the plan. In presenting the findings of the health impact assessment and discussing the recommendations, the paper presents a unique approach in health impact assessment reporting by offering perspectives from the assessor and the project's steering group.

The Cytosensor microphysiometer uses silicon chip technology to correlate changes in extracellular acidification rates with quantitative changes in cellular metabolism in response to ligand binding to surface receptors. This functional measure of physiology makes the Cytosensor a valuable tool in drug discovery research by allowing application of the instrument to screening of prospective pharmacologically active agents, characterizations of dose responses and structure-activity relationships, and investigation of mechanisms of action.
