    摘要: A diagnostic method and apparatus for assessing lung tissue during breathing, transmits ultrasonic radiation into the lung tissue; reflected or echo radiation, is reflected dynamically by air spaces in the tissue; a signal is developed from the reflected or echo radiation as a dynamic real-time measure of parameters of the air spaces, particularly size and density or number, indicative of the state of the lung tissue.

    摘要: Differentially expressed Leishmania genes and proteins are described. One differentially expressed gene (A2) is expressed at significantly elevated levels (more than about 10 fold higher) in the amastigote stage of the life cycle when the Leishmania organism is present in macrophages than in the free promastigote stage. The A2 gene encodes a 22 kD protein (A2 protein) that is recognized by kala-azar convalescent serum and has amino acid sequence homology with an S-antigen of Plasmodium falciparum Vietnamese isolate VI. Differentially expressed Leishmania genes and proteins have utility as vaccines, diagnostic reagents, as tools for the generation of immunological reagents and the generation of attenuated variants of Leishmania.
