In order to expand the currently limited understanding of atmospheric mercury source-receptor relationships in the Mexico City Metropolitan Area, real time measurements of atmospheric mercury were made at a downtown urban site, and a rural site on the outskirts of Mexico City, during March 2006. Numerous short-lived increases in particulate mercury (PHg)(More)
Organic carbon (OC) comprises a large fraction of fine particulate matter (PM 2.5) in Mexico City. Daily and select 12-h PM 2.5 samples were collected in urban and peripheral sites in Mexico City from 17–30 March 2006. Samples were analyzed for OC and elemental carbon (EC) using thermal-optical filter-based methods. Real-time water-soluble organic carbon(More)
In summary, our studies indicate that the perinatal mammalian brain shows considerable plasticity in response to trauma. Studies carried out both in vivo in the perinatal mouse brain and in vitro in cell line culture and organotypic slice cultures of developing brain tissue, indicate that the cytokine, interleukin-1 beta (IL-1 beta) regulates early healing(More)
The purpose of this work was to study the development of specific projections from the postero-lateral cortex during the third trimester of gestation in the mouse. To do this, we labeled undifferentiated lateral cortex with the fluorescent carbocyanine dye, Dil, in the embryonic day (E) 16 mouse embryo using exo utero surgical techniques (Muneoka, Wanek,(More)

Two months of treatment with rifampin-pyrazinamide (RZ) and 9 months of treatment with isoniazid are both recommended for treatment of latent tuberculosis infection in adults without human immunodeficiency virus infection, but the relative cost-effectiveness of these 2 treatments is unknown. We used a Markov model to conduct a cost-effectiveness analysis to(More)
