This paper describes the development of an auditory filterbank to perform the initial frequency analysis in models of human hearing and speech perception. It is based on the gammatone function used by physiologists to summarise 'revcor' measurements of the impulse response of the auditory filter in small mammals. The first section shows that the amplitude(More)
This study reports a 3-year follow-up of a classic presentation of hypersensitivity pneumonitis (HP), originally reported elsewhere, after removal of the causative antigens. The literature is reviewed and this case is compared with outcomes of series previously reported. The patient was reevaluated by clinical, serologic, radiographic, and pulmonary(More)
The purpose of this study was to examine the sensitivity and reliability of two tracking tests designed to measure control of handgrip force and finger movement. In one test, the subject exerts careful control of handgrip force on a dynamometer, which is interfaced with a computer, and attempts to guide a cursor as accurately as possible along a stationary(More)
1008 Background: The lower breast cancer incidence in minorities and higher breast cancer mortality in African Americans compared to Whites are largely unexplained. Therefore, relationships among ethnicity/race, breast cancer risk factors, and breast cancer were explored in an ethnically diverse cohort. METHODS Following comprehensive risk assessment,(More)
The antigenicity of polymerized grass (PG) and monomer grass (MG) was studied. As compared with MG, PG produces a similar immunologic response in rabbits as demonstrated by a tanned red blood cell (TRBC) passive hemagglutination assay or by total serum binding of perennial rye grass Group I antigens (RGGI). Six patients with allergic rhinitis sensitive to(More)

BACKGROUND Churg-Strauss syndrome (CSS), a necrotizing vasculitis characterized by asthma and eosinophilia, was described initially in 1951. Before the use of oral corticosteroids, the average patient survived for only a few months. Today with the use of oral corticosteroids and immunosuppressants, survival has increased significantly. METHODS We report(More)
