To clarify the role and regulation of eosinophils, we subjected several key eosinophil-related genetically engineered mice to a chronic model of allergic airway inflammation aiming to identify results that were independent of the genetic targeting strategy. In particular, mice with defects in eosinophil development (ΔdblGATA) and eosinophil recruitment [mice deficient in CCR3 (CCR3 knockout) and mice deficient in both eotaxin-1 and eotaxin-2 (eotaxin-1/2 double knockout)] were subjected to Aspergillus fumigatus-induced allergic airway inflammation. Allergen-induced eosinophil recruitment into the airway was abolished by 98%, 94%, and 99% in eotaxin-1/2 double knockout, CCR3 knockout, and Δdbl-GATA mice, respectively. Importantly, allergen-induced type II T helper lymphocyte cytokine production was impaired in the lungs of eosinophil- and CCR3-deficient mice. The absence of eosinophils correlated with reduction in allergen-induced mucus production. Notably, by using global transcript expression profile analysis, a large subset (29%) of allergen-induced genes was eosinophil- and CCR3-dependent; pathways downstream from eosinophils were identified, including in situ activation of coagulation in the lung. In summary, we present multiple lines of independent evidence that eosinophils via CCR3 have a central role in chronic allergic airway disease.

Abstract Objectives Biotin causes negative interference with thyroglobulin measurement using the Access thyroglobulin assay. Recently, Beckman reformulated the thyroglobulin assay to overcome biotin interference. We investigated the effect of biotin on both current and newly formulated assays. Methods Four serum pools were prepared using specimens containing various amounts of thyroglobulin. Then aliquots of each pool were supplemented with various amounts of biotin, and thyroglobulin concentrations were measured by both the current and the new assays. In addition, 3 volunteers ingested 10 mg biotin, and specimens were drawn before and 2 hours after taking biotin. Thyroglobulin concentrations before and 2 hours after taking biotin were measured by both assays. Results In the presence of biotin, thyroglobulin concentrations were reduced significantly using the current assay, but no significant change was observed using the newly formulated assay. We observed similar results in vivo. Conclusions The newly formulated thyroglobulin assay by Beckman is free from biotin interference.

The work presented in this thesis describes the development of a method to investigate α2-mediated responses in the tail and first order mesenteric resistance arteries of the mouse. Furthermore, responses mediated by α1-adrenoceptors have been studied and, in part, subtyped in these vessels. These aims were achieved by using a combination of subtype selective ligands and transgenic technology. α2-adrenoceptors, expressed in the tail artery, mediate contractile responses that at 31°C are susceptible to profound, persistent desensitisation. In the absence of a fully functional α2A/D receptor pool, contractions are affected by the way in which an agonist is administered. At 22°C, the α2-mediated response is significantly potentiated, a response that does not rely on the α2A/D subtype, but is critically dependent on previous exposure to an α1-selective agonist. In mesenteric resistance arteries, α2-adrenoceptors, proposed to exist on the endothelium, mediate vasodilatations. Responses depend on more than one α2-subtype, and are mediated by nitric oxide, and possibly EDHF. In the tail artery, α1A-adrenoceptors mediate contraction with little, if any, contribution from the α1B-subtype, and increasing age has little effect on the responses gained. Like the tail artery, the α1A-receptor subtype is the major receptor mediating contraction of mesenteric arteries. However, in the absence of the α1B-adrenoceptor, a small, but significant contraction, mediated by the α1D-adrenoceptor is uncovered. The use of subtype selective ligands and transgenic mice, has clarified the function of and α2 and α1-adrenoceptors in two mouse blood vessels, and allowed partial subtyping of the response. Alone, neither technique would have provided such clarity.

To help you get started on the path to academic success, here are some tips that have helped me as a college student for the past couple of years. 1. College campuses offer an abundance of places to concentrate and study. 8.

It's a neat experience being in that moment, having to keep in mind the time of day, the tides, the wind, the cloud coverage, the position of the sun, making sure your composition is pleasing and that your camera settings are correct for the right exposure.

Clear plastic storage bins are great for storing things like makeup, movies or magazines. Lots of stores like Bed, Bath & Beyond, have services that allow you to purchase what you need at home and then pick it up when you get to school.
