severe pediatric influenza in california, 2003-2005: implications for immunization recommendations.the 2003-2004 influenza season was marked by both the emergence of a new drift "fujian" strain of influenza a virus and prominent reports of increased influenza-related deaths in children in the absence of baseline data for comparison. in december 2003, the california department of health services initiated surveillance of children who were hospitalized in california with severe influenza in an attempt to measure its impact and to identify additional preventive measures.200616585278
predicting density of ixodes pacificus nymphs in dense woodlands in mendocino county, california, based on geographic information systems and remote sensing versus field-derived data.ixodes pacificus nymphs are the primary vectors to humans of borrelia burgdorferi, the etiologic agent of lyme disease, in california. we used a supervised classification model, based on remote sensing (rs) data from multi-seasonal landsat tm 5 images, to identify the key habitat in mendocino county where humans are exposed to i. pacificus nymphs (woodlands carpeted with leaf litter). the model, based on the normalized difference vegetation index (ndvi), brightness, and wetness, separated the ny ...200616606998
genetic polymorphisms and susceptibility to lung disease.susceptibility to infection by bacterium such as bacillus anthracis has a genetic basis in mice and may also have a genetic basis in humans. in the limited human cases of inhalation anthrax, studies suggest that not all individuals exposed to anthrax spores were infected, but rather, individuals with underlying lung disease, particularly asthma, sarcoidosis and tuberculosis, might be more susceptible. in this study, we determined if polymorphisms in genes important in innate immunity are associa ...200616608528
global challenges as inspiration: a classroom strategy to foster social responsibility.social responsibility is at the heart of the engineer's creed embodied in the pledge that we will dedicate [our] professional knowledge and skill to the advancement and betterment of human welfare... [placing] public welfare above all other considerations. however, half century after the original creed was written, we find ourselves in a world with great technological advances and great global-scale technologically-enabled peril. these issues can be naturally integrated into the engineering curr ...200616609724
life history and seasonal abundance of fannia benjamini complex (diptera: muscidae) in southern california.seasonal abundance and life history of fannia benjamini complex (diptera: muscidae) was studied in the coastal mountain community ofla habra heights in los angeles county, california, with additional observations in drier, inland mountains in the woodcrest area, riverside county. the dominant species (>95% of fly collections) was fannia conspicua malloch, whereas fannia benjamini malloch also was present. both species could be collected nearly year-round by netting adults (almost exclusively fem ...200616619598
role of corvids in epidemiology of west nile virus in southern california.the invasion of different southern california landscapes by west nile virus (wnv) and its subsequent amplification to epidemic levels during 2004 enabled us to study the impact of differing corvid populations in three biomes: the hot colorado desert with few corvids (coachella valley), the southern san joaquin valley (kern county) with large western scrub-jay but small american crow populations, and the cool maritime coast (los angeles) with a large clustered american crow population. similar su ...200616619622
geographical distribution patterns and habitat suitability models for presence of host-seeking ixodid ticks in dense woodlands of mendocino county, california.we used drag sampling to examine the geographical distribution patterns of ixodid ticks engaging in open (non-nidicolous) host-seeking behavior in dense woodland habitats of the climatically and ecologically diverse mendocino county in north coastal california. the findings based on this sampling methodology reflect risk of human exposure to host-seeking ticks rather than the true distribution of the ticks. drag sampling in 78 sites yielded 7,860 nymphal or adult ixodes pacificus cooley & kohls, ...200616619628
epidemiology and prevention.the 2006 conference on retroviruses and opportunistic infections marked the 13th year of this conference and the 25th anniversary of the first published cases of aids in gay men in los angeles. as noted in the opening plenary session, hiv has likely been present in the human population since the 1930s, and therefore represents a relatively recent disease for humans. however, by the end of 2005, more than 40 million persons were estimated to be living with hiv infection, and 5 million new infecti ...200616641523
