Tamoxifen (TXF; an antiestrogen), cyproterone acetate (CYP; an antiandrogen) and mifepristone (MIF; an antigestagen) did not affect kindling parameters (afterdischarge threshold, seizure severity, seizure duration and afterdischarge duration) in fully-kindled rats. TXF (50 mg/kg) and CYP (50 mg/kg), when combined with carbamazepine, or phenobarbital, both antiepileptics administered at their hi...

Mifepristone is a potent antagonist of steroid hormone receptors such as glucocorticoid and progesterone receptors. We investigated the potential for mifepristone to act as an antiandrogen and compared it with partial androgen receptor (AR) agonists and antagonists, in particular bicalutamide. Mifepristone was an effective antiandrogen in vitro that inhibited transcription from three androgen-r...

Using gene-specific synthetic oligonucleotides the expression and regulation of kallikrein-like genes in the human prostatic cancer cell line LNCaP were studied. Prostate-specific antigen (PSA) and human glandular kallikrein (hGK-1) together constitute a subfamily of serine proteases exclusively produced in the human prostate. RNA analysis revealed that both genes are expressed in LNCaP cells w...

We present the framework of an e!ective medium theory to calculate the transport properties of classical waves in disorderedmedia, Busch and Soukoulis (Phys. Rev. Lett. 75 (1995) 3442). It is based on the principle that the wave energy density should be uniform when averaged over length scales larger than the size of the basic scattering unit and can, therefore, be applied to electromagnetic, B...

We formalize the standard appli ation of identity-based en ryption (IBE), namely nonintera tive se ure ommuni ation, as realizing an ideal system whi h we all delivery ontrolled hannel (DCC). This system allows users to be registered (by a entral authority) for an identity and to send messages se urely to other users only known by their identity. Quite surprisingly, we show that existing se uri...

Homomorphic encryption schemes are an essential ingredient to design protocols where different users interact in order to obtain some information from the others, at the same time that each user keeps private some of his information. When the algebraic structure underlying these protocols is complicated, then standard homomorphic encryption schemes are not enough, because they do not allow to c...

Performance testing of the model-scale CPA was recently completed at the University of Texas Center for Electromechanics. A major part of the project was the development of design and simulation codes that would accurately represent the performance of pulsed alternators. This paper discusses the components of the system and its operational sequence. Details of the performance simulation model a...

phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. the monobasicbidentate coordination of the phenylazo derivative...
