The magnetic properties of the material allow for simple dispersion and removal from an aqueous system. An inquiry-based laboratory has been developed that illustrates these unique properties of magnetite nanoparticles while developing cross-disciplinary and critical-thinking skills. The versatility of the pedagogic approach makes it suitable for both high school (grades 11 and 12) and college-level STEM (science, technology, engineering, and math) courses. The lab experience exposes students to experimental design, environmental remediation, adsorption, and the surface area-to-volume ratio concept of nanotechnology.

Along with other clinical manifestations of the disease, elevated sputum and blood eosinophil levels are observed in patients experiencing asthma exacerbations. The aim of this study was to evaluate the association between blood eosinophil levels and asthma severity defined using Expert Panel Report 3 guidelines. Patients with asthma diagnosis between 2004 and 2011 were extracted from the EMRClaims+ database (eMAX Health, White Plains, NY) containing electronic medical records linked to insurance claims for over 675,000 patients. The date of first asthma diagnosis was defined as the 'index date'. Patients were required to have at least 1 peripheral eosinophil test (elevated defined as ≥ 400 cells/μL) in the 12 month 'assessment' period following the index date. We classified patients as those with mild asthma and moderate-to-severe asthma based on the pattern of medication use, ...

Biologic markers like blood eosinophils, that help predict the risk of exacerbation could help guide more optimal treatment plans and reduce cost. The purpose of this study was to determine whether healthcare resource use and expenditures vary by eosinophil level among patients with asthma. Patients with a diagnosis of asthma defined by ICD-9-CM code 493.xx between January 2004 and July 2011 were extracted from EMRClaims + database (eMAX Health, White Plains NY). Patients were classified as mild, moderate, or severe by medication use following diagnosis, based on recommendations of National Institutes of Health Expert Panel Report 3. Patients were classified as those with elevated eosinophils (≥400 cells/μL) and normal eosinophil level (<400 cells/μL). Patients were followed for resource use, defined as hospitalizations, ER visits and outpatient visit and associated costs were c...

We investigated the relation between blood eosinophil count and prospective annual asthma outcomes for a large UK cohort.
