Abstract: An apparatus for commercial transactions using a transaction card via a communication device in audio communication with a remote processor assembly is provided. The apparatus comprises an input device for capturing information from the transaction card, a controller for converting the captured card information into an audio signal. The controller is linked to the communication device. The apparatus may also be part of an assembly wherein this controller is part of the communication device. The remote processor assembly includes a transaction server linked to a remote processor/issuer for validating the transaction card data. A system including this apparatus, the communication device and the transaction server is also provided. Methods therefore are also disclosed.

Abstract: A mobile charger including a connector that facilitates charging at least one first battery from at least one second battery, wherein the second battery is a secondary battery and the second battery has a higher capacity than the first battery, thus allowing the first battery to be charged more than once; and a method for charging at least one first battery from at least one second battery, including connecting the second battery to the first battery with a secondary battery being used as the second battery to charge the at least one first battery, which secondary battery has a higher capacity than the first battery such that the first battery can be charged more than once.

Abstract: The present invention relates to novel geldanamycin derivatives which have antitumor and antiparasitic properties. The geldanamycin derivatives disclosed herein have antitumor properties in humans due to their interaction with human heat shock protein 90 (hsp90). The human parasites Plasmodium falciparum, Trypanosoma Cruzi, and Leishmania donovani are lethally susceptible to exposure to geldanamycin via complexation of geldanamycin with their homologs (Pfhsp90, hsp83, and hsp90, respectively) of the human hsp90. The geldanamycin derivatives disclosed herein also interact with these parasitic hsp90 homologs so as to have antiparasitic properties.

Abstract: A process for the preparation of hydroxyl substituted anthraquinones is described. The process couples a phthalic anhydride (substituted or unsubstituted) to benzene ring moiety substituted with at least two hydroxyl groups. Remaining hydroxy groups were converted to methoxy groups in some anthraquinones. The compounds are particularly useful for the treatment of parasitic diseases. Also, a method of treating or preventing malaria, filariasis schistosomiasis and other parasitic diseases using anthraquinones.
