Abstract: Interstitial cystitis (IC) is a chronic bladder disease for which the exact etiology is unknown and for which there is no reliably effective treatment. However, it is known that the bladder epithelium is often abnormal in IC. We discovered that normal, adult, human bladder epithelial cells are inhibited from proliferating by an anti-proliferative factor (APF) present in IC urine specimens. Inhibited proliferation may cause epithelial abnormalities characteristic of IC such as ulcerations and multiple tears in the bladder epithelium. We further discovered that levels of heparin binding—epidermal growth factor-like growth factor (HB-EGF), a factor known be important for epithelial cell proliferation and wound healing in other tissues, are abnormally low in the urine of patients suffering from IC as compared to asymptomatic controls or patients with acute bacterial cystitis. The invention herein is directed to the use of urine levels of HB-EGF as a diagnostic marker for IC.

Abstract: The present invention is directed to a gene encoding an adhesin polypeptide of Proteus mirabilis, the MrpH gene, its gene product, antigenic fragments of the adhesin polypeptide and antibodies directed against the MrpH gene product and fragments thereof. The present invention is also directed to a vaccine against Proteus mirabilis and treatment of Proteus mirabilis infection with anti-adhesin antibodies.

Abstract: The invention relates to a novel antiproliferative factor (APF) present in urine of patients with interstitial cystitis (IC). APF is useful as a marker for disease activity and its antagonists are useful as therapeutic medicaments for IC and other conditions associated with elevated APF. APF and its agonists are useful in the treatment of diseases associated with cell proliferation, such as bladder cancer.

Abstract: A novel antiproliferative factor (APF) present in urine of patients with interstitial cystitis (IC) is described. This urine antiproliferative factor can serve as a marker for disease activity and its antagonists as therapeutic medicaments for IC. In addition, APF and its agonists can be used for treating diseases associated with cell proliferation.

Abstract: A bimodal propulsion and power nuclear reactor with coaxial power and propulsion cores, each with its own primary propellant/coolant. An inner core region provides electrical power while an outer annular core region surrounding the inner core region has, passageways for heating a gaseous propellant.
