Background: Daily clinical observations and a recent study (D Vermeylen et al., 2004) suggest that reflux laryngitis (RL) is involved in apneas/ bradycardias of the newborn. The aim of this study is to develop and tovalidate a unique RL model in newborn lambs to test the assumption that a RL provokesan increase in apneas/ bradycardias/ desaturations observed within thelaryngeal chemoreflexes induced by the contact of a liquid with the larynx. Methods: A surgical instrumentation was performed on the first day of life, which included the insertion of a transcutaneous esophageal catheter in order to allow instillation of a gastric juice surrogate (HCl +pepsin at pH 2) directly on the larynx. The 2 ml-instillations were made 3 times per day for 6 consecutive days. At day 9-10 laryngeal chemoreflexes were induced during sleep. The larynx was removed at the time of necropsy to grade inflammation by a histological study. Results: Lambs in which a RL was induced (n = 4) presented characteristic signs of RL: cough, weak bleat, reduction in weight gain. Preliminary histological analyses showed a characteristic laryngeal inflammation. Preliminary results showing that apneas and oxygen desaturations seem more prominent in RL lambs than controls provided further validation ofour RL model. Conclusion: The ovine model developed in this study presents theclinical and histological characteristics of RL observed in newborns. Preliminary results suggesting that a RL increases apneas/bradycardias/desaturations when a liquid is in contact with laryngealmucosa in the newborn must be confirmed.

In this chapter, a model of online shopping experience is proposed to unify previous works of online consumer experience. Online shopping experience (OSE) is the interaction between shoppers and commercial web sites. It consists of physical, cognitive, and affective activities, and in-progress responses. Factors influencing shopping experience include individual characteristics of shoppers, characteristics of stores and commercial web sites, characteristics of products and shopping task, and other contextual factors. The outcomes of shopping experience have been studied in many ways. Based on this model, series of research questions can be asked to examine relationships between components of shopping experience and influencing factors, and between shopping experience and shopping outcomes. Preliminary results of a study are reported to illustrate the usefulness of the concept of online shopping experience.
