Comparison of gene expression in intra-abdominal and subcutaneous fat: a study of men with morbid obesity and nonobese men using microarray and proteomics.

Extent of intra-abdominal fat had significant linear relations with six metabolic coronary risk factors: systolic and diastolic blood pressure, fasting blood concentrations of glucose, high density lipoprotein (HDL) cholesterol, triglyceride, and plasminogen activator inhibitor-1. Tumor necrosis factor-alpha and adiponectin can be biological mediators from the intra-abdominal fat to the metabolic coronary risk factors. Complementarily, we describe a new study that will analyze the gene expression in intra-abdominal and subcutaneous fat on mRNA and protein level using high throughput methods. The study will elucidate further whether intra-abdominal obesity is the common denominator for the different components of the metabolic syndrome.

The quantification of gluconeogenesis in healthy men by (2)H2O and [2-(13)C]glycerol yields different results: rates of gluconeogenesis in healthy men measured with (2)H2O are higher than those measured with [2-(13)C]glycerol.

The quantification of gluconeogenesis (GNG) by (2)H2O and [2-(13)C]glycerol and the mass isotopomer dilution analysis of glucose does not involve assumptions regarding the enrichment of the oxaloacetate precursor pool. To compare these two methods we measured GNG in six healthy postabsorptive males under identical, strictly standardized, eucaloric conditions, once after oral administration of (2)H2O and once during a primed continuous infusion of [2-(13)C]glycerol. Endogenous glucose production (EGP) was measured by infusion of [6,6-(2)H(2)]glucose. EGP was not different after (2)H2O administration or during [2-(13)C]glycerol infusion (12.2 +/- 0.7 vs. 11.7 +/- 0.3 micromol/kg.min). However, GNG measured after (2)H2O administration was significantly higher than that during [2-(13)C]glycerol infusion (7.4 +/- 0.7 vs. 4.9 +/- 0.6 micromol/kg.min; P = 0.03), representing approximately 60% and 41% of EGP, respectively. The (2)H2O study was repeated during primed continuous infusion of unlabeled glycerol, showing that infusion of glycerol at the rate used in the [2-(13)C]glycerol method does not affect the measurement of GNG with (2)H2O, viz. 7.4 +/- 0.7 without glycerol vs. 7.6 +/- 0.9 micromol/kg.min with glycerol, representing approximately 60% vs. 62% of EGP. In conclusion, GNG measured by (2)H(2)O yields higher results than those measured by [2-(13)C]glycerol. This discrepancy is not merely caused by infusion of glycerol per se. Rather, the discrepancy between both methods probably relates to conceptual problems in underlying assumptions in one or both methods.

Homosexual men (and lesbian men) in a heterosexual genre: three gangster films from Hong Kong.

Of the East Asian film genres that have captured the attention of film goers internationally, it should be of little surprise that martial and heroically masculine genres have been the most popular, for violent action translates well into any language. Although it has been no secret that male martiality often leaks into homoerotic desire (on the part of the audience, too), three Hong Kong films from 1998 have finally explicated the generic homosexuality that the action genre has been (defensively) ashamed to admit all along. However, rather than posit this textual homosexuality as transgressive, the generic forces under which these films operate rewrite their homosexualities, both gay and lesbian, into generic modes fashioned around regressive oppositions of gender, and not progressive liberations of sexuality.
