| biologic effects induced in vitro by pm10 from three different zones of mexico city. | exposure to urban airborne particles is associated with an increase in morbidity and mortality. there is little experimental evidence of the mechanisms involved and the role of particle composition. we assessed cytotoxicity (crystal violet assay), apoptosis [terminal deoxynucleotidyl transferase-mediated dutp nick-end labeling (tunel) or annexin v assay], dna breakage (comet assay), and production of proinflammatory mediators [tumor necrosis factor alpha (tnf-alpha), interleukin 6 (il-6), prosta ... | 2002 | 12117649 |

| evaluation of candidate genes in a genome-wide association study of childhood asthma in mexicans. | more than 200 asthma candidate genes have been examined in human association studies or identified with knockout mouse approaches. however, many have not been systematically replicated in human populations, especially those containing a large number of tagging single nucleotide polymorphisms (snps). | 2010 | 19910030 |
| urban air pollution targets the dorsal vagal complex and dark chocolate offers neuroprotection. | mexico city (mc) residents exposed to fine particulate matter and endotoxin exhibit inflammation of the olfactory bulb, substantia nigra, and vagus nerve. the goal of this study was to model these endpoints in mice and examine the neuroprotective effects of chocolate. mice exposed to mc air received no treatment or oral dark chocolate and were compared to clean-air mice either untreated or treated intraperitoneally with endotoxin. cyclooxygenase-2 (cox-2), interleukin 1 beta (il-1β), and cd14 me ... | 2010 | 21030725 |
