    Abstract: We have now discovered that unexpectedly compounds of the following formulae I or 11 can be used to selectively stimulate the death of mammalian prostate cells, including both epithelial cell and prostate cancer cells, and thus are useful in treating prostate diseases: wherein R and R1 are each independently selected from the group consisting of hydrogen, hydroxy, thio (SH), halogen, substituted and unsubstituted alkyl, substituted and unsubstituted alkenyl, substituted and unsubstituted aryl, and substituted and unsubstituted alkoxy, and salts thereof, wherein the dotted double bond between the ring carbons to which R and R1 are bonded represent an optional ring double bond. Preferred compounds of formula I include those in which at least one of the substituents R and R1 is hydrogen and/or at least one of said substituents is allyl. Specifically preferred compounds include &bgr;-lapachone (i.e., R and R1 both being hydrogen), allyl-&bgr;-lapachone, particularly 3-allyl-&bgr;-lapachone (i.e. R being allyl and R1 being hydrogen) and 3-bromo-&bgr;-lapachone (i.e. R being bromo and R1 being hydrogen).

    Abstract: A method produces calcium fulvate from naturally-occurring humus material, such as leonardite, or humic shales. The humus material containing solid fulvic acid and solid humic acid is mixed with water and sodium hydroxide for a first selected period of time to form a solution having a pH of approximately 10.0 thereby solubilizing the fulvic acid and the humic acid. The pH of the solution is reduced to approximately 4.5 and is maintained at the approximately pH 4.5 for second selected period of time thereby precipitating the humic acid as a solid while the fulvic acid remains in solution. The fulvic acid solution is separated from the solid humic acid. The pH of the fulvic acid solution is increased to approximately 13 with calcium hydroxide thereby precipitating the solubilized fulvic acid as calcium fulvate.

    Abstract: Systems, including compositions and methods, for measuring pH, particularly in cells, organelles, and other samples. The compositions include pH-sensitive fluorescent and fluorogenic 2′,7′-dialkylfluorescein derivatives and associated nonfluorescent precursor compounds. The compositions may permit ratiometric measurement in the excitation spectrum and the emission spectrum. The methods include adding a precursor compound to a sample cell, incubating the sample cell to release the free indicator, illuminating the sample cell, and detecting the fluorescence response of the free indicator.
