1 Introduction Inflammation is one of the main mechanisms in the pathogenesis of atherosclerosis,and the interest to the evaluation of inflammatory biomarkers in coronary artery disease(CAD)has been increasing over the last decade.[1,2]Destabilization of chronic artery plaques,which leads to acute coronary syndromes,has been associated with inflammatory status.[1,3]。

Severtsov Institute of Ecology and Evolution Russian Academy of Sciences Leninskij prospekt 33 Moscow 119071 Russia Zoological Museum of Lomonosov Moscow State University Bolshaya Nikitskaya B Moscow 125009 Russia

The majority of our knowledge of avian energetics is based on studies of birds from temperate and high latitudes. Using the largest existing sample of wild-caught Old World tropical species, we showed that birds from Southern Vietnam had lower basal metabolic rate （bMR） than temperate species. The strongest dissimilarity between tropical and temperate species was the low scaling exponent in the allometric relation between bMR and body mass in tropical birds （the regression slope was 0.573）. The passerine migrants to temperate and high latitudes had higher bMR than tropical sedentary passerines. body mass alone accounted for 93% of the variation in bMR （body mass ranged from 5 to 252 g）. Contrary to some other studies, we did not find evidence besides the above mentioned that phylogeny, taxonomy, behavior, or ecology have a significant influence on bMR variation among tropical birds.
