α-Amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2ZnCl2 as a bio Lewis acidic ionic liquid. Mild Lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.

An objective system for histopathological and statistical evaluation of rat bladder lesions induced by the carcinogen, N-methyl-N-nitrosourea, is described. This system has been used to measure the inhibitory effects of 13-cis-retinoic acid on the development of bladder cancer in female Wistar/Lewis rats. 13-cis-Retinoic acid caused significant inhibition of development of both preneoplastic an...

It has previously been reported that synthetic peptides corresponding to sequences derived from T-cell receptor variable regions identified as dominant in the T-cell-mediated autoimmune disease experimental allergic encephalomyelitis in both the mouse and the rat can down-regulate disease in Lewis rats. In contrast to these results, we have found that immunization of Lewis rats with such peptid...

Experimental autoimmune uveitis (EAU) in Lewis rats is a well-established model for human uveitis. During the last years we used this model to demonstrate extraocular induction of uveitis by antigenic mimicry of environmental antigens with retinal autoantigen and investigated the migration and intraocular reactivation of autoreactive green fluorescent protein (GFP)+ T cells. We could also elabo...

Experimental autoimmune encephalomyelitis (EAE) in Lewis rats is an acute monophasic paralytic central nervous system disease, in which most rats spontaneously recover from paralysis. EAE in Lewis rats is induced by encephalitogenic antigens, including myelin basic protein. EAE is mediated by CD4(+) Th1 cells, which secrete pro-inflammatory mediators, and spontaneous recovery is mediated by reg...
