Abstract: Compounds, compositions and methods are provided that comprise selective ?-glucuronidase inhibitors for both aerobic and anaerobic bacteria, especially enteric bacteria normally associated with the gastrointestinal tract. The compounds, compositions and methods can be for inhibiting bacterial ?-glucuronidases and for improving efficacy of camptothecin-derived antineoplastic agents or glucuronidase-substrate agents or compounds by attenuating the side effects caused by reactivation by bacterial ?-glucuronidases of glucuronidated metabolites of camptothecin-derived antineoplastic agents or glucuronidase-substrate agents or compounds.

Abstract: The proposed device is based on a carbon nanotube oscillator consisting of a finite length outer stationary nanotube and a finite length inner oscillating nanotube. Its main function is to measure changes in the characteristics of the motion of the carbon nanotube oscillating near a sample surface, and profile the roughness of this surface. The device operates in a non-contact mode, thus it can be virtually non-wear and non-fatigued system. It is an alternative to the existing atomic force microscope (AFM) tips used to scan surfaces to determine their roughness.

Abstract: The invention provides pharmaceutical compositions comprising hypolipidemically active derivatives of 1,2,4-triazolidine-3,5-diones, 1,3,5-triazabicyclo[3.1.0]hexane-2,4-diones, and 1,3,5-triazine-2,4(1H,3H)-diones in a pharmaceutically acceptable carrier for treating hyperlipidemia in mammals, particularly humans.
