The effects of feeding Fusarium moniliforme culture material, containing known concentrations of fumonisin Bj (FBi), were studied in turkey poults. Day-old poults were allotted randomly to dietary treatments containing 0, 0.41, 0.82, 1.23, 1.64, 2.87, 4.10, 5.33, 6.56, and 7.79% fumonisin culture material (FCM). These levels of FCM supplied 0, 25, 50, 75, 100, 175, 250, 325, 400, and 475 mg FBi...

We have evaluated the possibility that conserved cysteine residues are critical for the enzymatic function of p56lck. Through oligonucleotide-directed mutagenesis, 5 Lck residues (cysteines 217, 224, 378, 464, and 475) were individually mutated to alanines, and the effects of these substitutions were tested in various in vitro and in vivo assays. We found that mutation of either of 2 cysteines ...

Site-directed mutagenesis was applied to modify phenylalanines (Phe(475)Trp, Phe(548)Tyr, and both) to generate mutants on the basis of molecular modeling of the ATP-binding domain of Na(+)/K(+)-ATPase, in order to characterize the forces that stabilize ATP in its binding pocket. Each of the mutants was examined by Raman difference spectroscopy, i.e., as a difference between the spectrum of the...

Algebraic attacks on stream ciphers [9] recover the key by solving an overdefined system of multivariate equations. Such attacks can break several interesting cases of LFSR-based stream ciphers, when the output is obtained by a Boolean function, see [9– 11]. Recently this approach has been successfully extended also to combiners with memory, provided the number of memory bits is small, see [1, ...
