  • Patent number: 6376503
    Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.

  • Patent number: 6326617
    Abstract: Photoelectron spectroscopy apparatus are disclosed that comprise a photoelectron detector and that exhibit improved performance of the photoelectron detector and thus more reliable and accurate analysis of photoelectron energy. In performing energy analysis of photoelectrons, the photoelectron detector measures the time distribution at which photoelectrons emitted from a specimen surface traverse a flight tube when the specimen is irradiated with X-rays from a pulse X-ray source. A magnetic field generator is situated near the specimen to collect and collimate photoelectrons emitted from the specimen surface and form a photoelectron flux inside a flight tube.
