Purpose: Weight gain is an important risk factor for the development of the metabolic syndrome, and inflammatory mediators are strongly associated with this syndrome. Our aim was to investigate whether inflammation predicts the development of weight gain in populations. Research Methods and Procedures: We investigated selected markers of inflammation in the prediction of weight gain over an approximately 3‐year period in a biethnic cohort of 13,017 men and women, 45 to 64 years of age, using multiple linear and logistic regression modeling. Results: In adjusted models, those in the highest quartile of fibrinogen gained, during the first 3 years of follow‐up, an estimated 0.23 kg/year more than those in the lowest quartile (p < 0.001). Adjusted odds of a large (greater than the 90th percentile) weight gain for those in the highest quartile of fibrinogen were 1.65 (95% confidence interval [CI], 1.38 to 1.97) times those in the lowest quartile. Similarly adjusted odds ratios for a large weight gain for those with high levels of white blood cell count, factor VIII, and von Willebrand factor were 1.38 (1.14 to 1.67), 1.28 (1.08 to 1.53), and 1.28 (1.08 to 1.51), respectively. Discussion: Fibrinogen and other putative markers of inflammation predict weight gain in middle‐aged adults. Given the known links between the inflammatory response and intermediary metabolism and the methodological strengths of the Atherosclerosis Risk in Communities (ARIC) cohort, these findings, though without immediate clinical applicability, suggest that inflammatory processes play a role in the development of the metabolic syndrome and cardiovascular disease in part through stimulation of weight gain. 相似文献

The study of adaptation requires the integration of an array of different types of data. A single individual can find such integration daunting, if not impossible. In an effort to clarify the role of diet in the evolution of the primate craniofacial and dental apparatus, we assembled a team of researchers that have various types and degrees of expertise. This interaction has provided a range of insights for all contributors, and this has helped to refine questions, clarify the possibilities and limitations that laboratory and field settings offer, and further explore the ways in which laboratory and field data can be suitably integrated. A complete and accurate picture of dietary adaptation cannot be gained in isolation. Collaboration provides the bridge to a more holistic view of primate biology and evolution. 相似文献

Summary The bacteriophage T4 uvsX gene encodes a 43 kDa, single-stranded DNA-dependent ATPase, double-stranded DNA-binding protein involved in DNA recombination, repair and mutagenesis. Mutants of uvsX have a DNA-arrest phenotype and reduced burst size. Western blot immunoassay of UvsX peptides made by a number of amber mutants revealed amber peptides ranging from 25–32 kDa. Wild-type UvsX protein was also detected in lysates of cells infected with uvsX amber mutants, suggesting that their mutations are suppressed by translational ambiguity. We investigated the effects of mutations near the 5 end of uvsX. A frameshift mutation was engineered at codon 33. Western immunoblots for UvsX protein demonstrated that the frameshift mutant expresses no detectable wild-type UvsX; instead, a 37 kDa reactive peptide was detected. In order to determine if this peptide represents truncated UvsX protein, the mutation was regenerated in the cloned uvsX gene and expressed in transformed Escherichia coli. Endopeptidase digestion of the 37 kDa protein from the cloned gene generated peptide fragments indistinguishable from those obtained from wild-type UvsX. A double-amber mutant of uvsX was also generated by oligonucleotide site-directed mutagenesis. No UvsX protein was detected in lysates of cells infected with the uvsX-am64am67 double mutant. Plaque size and sensitivity to UV inactivation for both the double-amber and the frame-shift mutants were indistinguishable from those of other uvsX mutants. Mutations in uvsY had no demonstrable effect on efficiency of plating or UV sensitivity of uvsX mutants. Thus, null mutants of uvsX are viable. 相似文献
