Observed seasonal differences in particulate matter (PM) associations with human health may be due to their composition and toxicity-related interactions.We assessed seasonality PM vitro pro-inflammatory potential using multiple samples.We collected 90 weekly PM10 PM2.5 samples during the rainy-warm dry-cold seasons five urban areas different pollution sources. The elements, polycyclic aromatic hydrocarbons (PAHs), endotoxins identified were subjected principal component analysis (PCA). We...
Endocrine disrupting chemicals (EDCs) from the environment are associated with reproductive abnormalities (i.e. decreased sperm concentration; increased endometriosis) and alterations of cardiovascular system blood pressure risk coronary disease). Some phthalates esters have been identified as EDCs, for which inhalation is considered one routes exposure. However, only little known regarding inhalational exposure to EDCs via urban airborne particles. In present study, we report monthly...
Pseudomonas aeruginosa has different resistant mechanisms including the constitutive MexAB-OprM efflux pump. Single nucleotide polymorphisms (SNPs) in mexR, nalC, and nalD repressors of this pump can contribute to antimicrobial resistance; however, it is unknown whether these changes are mainly related genetic lineages or environmental pressure. This study identifies SNPs genes clinical isolates P. (including high-risk clones). Ninety-one strains were classified according their resistance...
La asignatura Matemáticas, suele tener un componente de dificultad añadido que en muchos casos obedece a el alumno aborda la con planteamiento excesivamente mecanicista, orientado fundamentalmente resolución ejercicios. Esto limita otros aspectos necesarios como capacidad comprensión conceptos, manejo fluido del lenguaje matemático y especialmente entendimiento su utilidad economía, no solo desde enfoque académico, sino también eminentemente práctico, para vida cotidiana. prensa supone gran...
A natural wetland in Mexico City Metropolitan Area is one of the main suppliers crops and flowers, consequence its canals hold a high concentration organochlorine (OC) organophosphorus (OP) pesticides. There also an extensive population water hyacinth (Eichhornia crassipes), which considered plague; but literature suggests may be used as phytoremediator. This study demonstrates bioaccumulation difference for OC vivo suggesting their ruled by log Kow, while all OP showed regardless Kow. The...
Regional environmental assessments aim to synthesize the complex dynamics of socioenvironmental systems facilitate sustainable policymaking. Theoretically, these serve as ‘boundary objects’ that link scientific knowledge and policy making within a multiagency context. Nevertheless, achieving boundary object is challenging because significant technical uncertainties, well contrasting perceptions, values, ideologies regarding issues concern. Drawing on theoretical developments concerning...
Recurrent personal exposure to ambient PM2.5 is associated with adverse human health effects, in particular on the respiratory and cardiovascular systems. Here, we present an assessment of inhalation for five modes transport (walking, cycling, public bus (trolleybus diesel bus), conventional car (CC) hybrid-electric (HEC)) two routes similar distance, along a major road Mexico City metropolitan area (MCMA). Arithmetic average concentrations ranged from 16.5 ± 6.5 µg m−3 walking 81.7 9.1...
Use of solid fuels for cooking or home heating has been related to various diseases the respiratory tract. Woodsmoke contains a mixture carcinogenic polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds. Inhalation these material induces local systemic changes in immune system which may impair critical cell defense mechanisms; however, few studies have investigated early effects that PAH exposures on cells as macrophages. The aim this study was analyze if pre-exposure PAHs...
The dispersal of diaspores is a key process for successful reproduction, survival and evolution plants. To model the biological propagules (e.g., spores, pollen) it necessary to measure their terminal velocity (Vt) in air. In this study, we used new method based on video image analysis Vt spores seven fern taxa. average was 7.0 cm s−1, but varied among species from 1.6 11.3 s−1. Similar values were reported previously airborne particles mosses seed Spores Danaea nodosa Lophosoria...
Recent multidrug resistance in Pseudomonas aeruginosa has favoured the adaptation and dissemination of worldwide high-risk strains. In June 2018, 15 P. strains isolated from patients a contaminated multi-dose meropenem vial were characterized to assess their association an outbreak Mexican paediatric hospital. The by antibiotic susceptibility profiling, virulence factors' production, biofilm formation. clonal relationship among isolates was determined with pulse-field gel electrophoresis...
