Abstract: The present invention relates to a method of inhibiting angiogenesis in a biological system. The method includes administering to the biological system an effective amount of a steroid saponin.

Abstract: The present invention relates to a method of inhibiting growth of a cancerous cell. The method includes the step of exposing the cancerous cell to an anti-cancer therapy and an effective amount of a steroid saponin.

Abstract: A fluid sprayer system using a modulated hydraulic control valve and a positive displacement pump to control the amount of fluid sprayed by the system. The modulated hydraulic control valve may be controlled using pulse width modulation and may be provided with a substantially constant source of hydraulic fluid. The pulse width modulated hydraulic control valve provides the hydraulic fluid to a hydraulic motor as a controlled flow. The controlled flow serves to control the hydraulic motor that controls a positive displacement pump. The position displacement pump is used to control the amount of fluid sprayed by the system. The control system changes the signal to the control valve so as to mitigate pressure changes otherwise caused by said positive displacement pump.

Abstract: Hard gelatin capsules contain: (a) a fat-soluble nutrient, such as a fat-soluble vitamin (A, D, E or K) or an unsaturated fatty acid glyceride; (b) a nonionic surfactant, such as a polyoxyethylated (optionally hydrogenated) castor oil, and/or a polyethylene glycol; (c) a gelatin softening agent such as glycerol, propylene glycol or, preferably, glyceryl mono-oleate; and optionally (d) water. The problems of embrittlement conventionally encountered with hard gelatin capsules containing fat-soluble nutrients are reduced or avoided.
