Experimental PVC Material Challenge in Subjects with Occupational PVC Exposure
BACKGROUND Polyvinyl chloride (PVC) materials have been linked to asthma in several epidemiologic studies, but the possible causal factors remain unknown. PARTICIPANTS We challenged 10 subjects experimentally to degraded PVC products under controlled conditions. All of the subjects had previously experienced respiratory symptoms suspected to be caused by this kind of exposure in their work pl...
متن کاملAutoantibodies to phosphatidylethanolamine (PE) recognize a kininogen-PE complex.
Demonstration of autoimmune antiphospholipid antibodies (aPA) to negatively charged phospholipids (PL) in an enzyme-linked immunosorbent assay (ELISA) requires the presence of certain phospholipid-binding plasma proteins, eg, beta 2-glycoprotein I. We found a requirement for plasma against the electrically neutral or zwitterionic phospholipid, phosphatidylethanolamine (PE). Two of these PE-bind...
متن کاملChemical Modification of Pvc
The degradation of PVC at a processing temperature is mostly caused by its abnormal and unsta— ble molecular structures. It has been pointed out that its allyl chloride structures play a significant role as the abnormal and unstable structures. Inasmuch as the allyl chloride struc— tures are markedly more chemically active than the normal structure, the selective chemical treatments are applica...
متن کاملSparseness and speech pe
Can we model speech recognition in noise by exploring higher order statistics of the combined signal? How will changes in these statistics affect speech perception in noise? This study addresses these questions in two experiments. One investigated the relationship between an established ”glimpsing” model and the fourth order statistic, kurtosis. The glimpsing model [1] proposes that listeners c...
متن کامل- - - - XTP / PE Design Considerations †
The Xpress Transfer Protocol, XTP, is an approach to protocol design for next generation networks. The Protocol Engine, PE, is a hardware architecture for implementing network protocols and system interfaces using VLSI techniques. The two projects are related: XTP is designed with a PE in mind. This paper presents some of the ideas and goals in XTP. Introduction XTP [1] represents a compromise ...
