We propose two public-key broadcast encryption schemes. Our Scheme1 is a variant of the dynamic broadcast encryption scheme proposed by Delerablée et al.[9]. The computational cost and the encryption (public) key size are more efficient than the original scheme. We observe that by using a decryption key in the original scheme, we can encrypt a message more efficiently without a part of an encryption...
A series of umbelliferone aminoalkyl derivatives, previously studied as inhibitors of squalene-hopene cyclase, were tested as inhibitors of yeast (Saccharomyces cerevisiae) oxidosqualene cyclase (OSC) and OSC from Trypanosoma cruzi and Pneumocystis carinii expressed in yeast. Enzymes from these pathogens were included in this study to provide a preliminary screening for antiparasitic activity. Tests...
