"Obesity" and "Clinical Obesity" Men's understandings of obesity and its relation to the risk of diabetes: A qualitative study
<p>Abstract</p> <p>Background</p> <p>The 2007 Wanless report highlights the ever increasing problem of obesity and the consequent health problems. Obesity is a significant cause of diabetes. An increasing evidence base suggests that in terms of reducing diabetes and CVD risk, it is better to be "fit and fat" than unfit and of normal weight. There has been very little previous research into the understandings that men in the general population hold about the issues of weight, exercise and health; we therefore undertook this study in order to inform the process of health promotion and diabetes prevention in this group.</p> <p>Methods</p> <p>A qualitative study in North East England General Practice using a purposive sample of men aged 25 and 45 years (selection process designed to include 'normal', 'overweight' and 'obese' men). One to one audio-recorded semi structured interviews focused on: overweight and obesity, diet, physical activity and diabetes. Transcripts were initially analysed using framework analysis. Emerging themes interlinked.</p> <p>Results</p> <p>The men in this study (n = 17) understand the word obesity differently from the clinical definition; "obesity" was used as a description of those with fat in a central distribution, and understandings of the term commonly take into account fitness as well as weight. Men in their late 30s and early 40s described becoming more aware of health issues. Knowledge of what constitutes a 'healthy lifestyle' was generally good, but men described difficulty acting upon this knowledge for various reasons e.g. increasing responsibilities at home and at work. Knowledge of diabetes and the link between obesity and diabetes was poor.</p> <p>Conclusion</p> <p>Men in this study had a complex understanding of the interlinked importance of weight and fitness in relation to health. Obesity is understood as a description of people with centrally distributed fat, in association with low fitness levels. There is a need to increase understanding of the causes and consequences of diabetes. Discussion of increased health awareness by men round the age of 40 may indicate a window of opportunity to intervene at this time.</p
Nonhalogenated organic molecules from Laurencia algae
The marine red algae of the genus Laurencia have produced more 700 secondary metabolites and exhibited high molecular diversity and intriguing bioactivity. Since the halogenated structures have been comprehensively reviewed previously, this review, covering up to the end of 2012, mainly focuses on the source, structure elucidation, and bioactivity of nonhalogenated organic molecules from Laurencia spp. as well as the relationship between nonhalogenated and halogenated products. Overall, 173 new or new naturally occurring compounds with 58 skeletons, mainly including sesquiterpenes, diterpenes, triterpenes, and C15-acetogenins, are described.The marine red algae of the genus Laurencia have produced more 700 secondary metabolites and exhibited high molecular diversity and intriguing bioactivity.

S-Adenosylmethionine May Mitigate Obstructive Sleep Apnea in an Adult with Down Syndrome: A Case Report
Obstructive sleep apnea (OSA) is common in individuals with Down syndrome (DS). These patients are characterized by reduced levels of S-adenosylmethionine (SAMe) due to a depression of mitochondrial methylation capacity, and its implementation may improve cognitive performance. Based on the above, it is likely a beneficial effect in the treatment with SAMe also on the quality of the sleep. We report the case of an adult male with DS who received benefit of SAMe administration during OSA treatment with CPAP. We observed a significant improvement of apnea/hypopnea index (AHI), which has never been previously reported in Down individuals. AHI dropped from 51.2 to 17.2 from 0 to 49 months
STRUCTURAL INVESTIGATION ON 1-AMINO-ARYL-METHYLPHOSPHONATE ESTERS. X-RAY STRUCTURE OF O,O
Resolution of phthalans obtained by ortho-litiathion of aryloxiranes by enantioselective high-performance liquid chromatography: Performances of various chiral stationary phases
The HPLC separation of the enantiomers of six phthalans (1,3-dihydrobenzo[c]furans) synthesized as racemic mixtures from ortho-lithiated aryloxiranes was accomplished in the normal-phase mode using seven polysaccharide-derived and Pirkle-type chiral stationary phases (CSPs) and n-hexane/2-propanol mixtures as mobile phases. Separation and resolution factors up to 1.6 and 4.2, respectively, were obtained. The performances of various CSPs with regard to the same compound were, however, quite different not only between the two types of CSPs but also within the same type (polysaccharide-derived or Pirkle-type). Also diastereomeric pairs of phthalans show different enantioseparation using the same CSP

Resolution of inherently chiral 1,4-2,5-calix[8]bis-crown-4 derivatives by enantioselective HPLC
The first example of the resolution of inherently chiral calix[8]arenes, 1,4-2,5-calix[8]bis-crown-4 1 and its methyl derivatives 2-4, has been achieved using enantioselective HPLC methods. The enantiomeric nature of isolated (+)-1 and (-)-1 was confirmed by CD spectra, specific optical rotation and H-1 NMR in the presence of Pirkle's reagent. A rationale is given for the observed HPLC enantioselectivity among compounds 2-4. (C) 1997 Elsevier Science Ltd
The Structure of Laurobtusol, A New Rearranged Sesquiterpenoid From the Mediterranean Red Alga Laurencia-obtusa
An alcohol with a new tricyclic humulane skeleton, laurobtusol, was isolated from the Mediterranean Red Alga Laurencia obtusa. The structure was established mainly by 2 D NMR methods and the relative configuration was assigned by a quantiative computer simulation of the lanthanide induced shifts in the H-1 NMR spectrum and Molecular Mechanics calculation (MM2)
