The Poisson distribution is often used as a standard probability model for data involving counts. Quite often, however, such datasets are not well fit by a Poisson model because they contain more zero counts than are compatible with the Poisson model. For these situations, a zero-inflated Poisson (ZIP) distribution is often proposed. This article addresses testing a Poisson versus a ZIP model, ...

Secondary growth and the development of woody tissue is a key process in the formation of woody biomass. The gene family of Class III HDZip genes has been shown in the herbaceous Arabidopsis model to play a central role in regulating polarity and vascular development. While Arabidopis is a poor model for investigating processes of wood formation, in this project all poplar Class III HDZip genes...

Activation of transcription factors by receptor mediated signaling is an essential step for T lymphocyte effector function. Following antigenic stimulation of T cells the two central cytokines IL-2 and TNFalpha are co-expressed and co-regulated. Two important transcription factors, i.e., early growth response (EGR) protein EGR-1 and nuclear factors of activated T cells (NFAT) protein NFATc, reg...

BACKGROUND Environmental exposure to persistent organic pollutants (POPs) may lead to elevation of serum lipids, increasing risk of atherosclerosis with thromboembolism, a recognized cause of stroke. We tested the hypothesis that exposure to contaminants from residence near hazardous waste sites in New York State influences the occurrence of stroke. METHODS The rates of stroke hospital discha...

We have examined rates of hospitalization for respiratory diseases in relation to residences in zip codes with hazardous waste sites, as well as socio-economic status. Chronic bronchitis and chronic airway obstruction were elevated in persons who live in zip codes containing persistent organic pollutants (POPs) (PCBs and persistent pesticides) as compared to "clean" zip codes without hazardous ...

BACKGROUND Socioeconomic status (SES) as reflected by residential zip code status may detrimentally influence a number of prehospital clinical, access-related, and transport variables that influence outcome for patients with ST-elevation myocardial infarction (STEMI) undergoing reperfusion. We sought to analyze the impact of SES on in-hospital mortality, timely reperfusion, and cost of hospital...

Trichomonas vaginalis infection in males has been largely uncharacterized. Past reports indicated increased susceptibility to other sexually transmitted infection (STI) agents such as human immunodeficiency virus and Neisseria gonorrhoeae with concurrent T. vaginalis infection. This warrants a more thorough review of male T. vaginalis incidence. A retrospective 3-year investigation of transcrip...
