Many developing neural systems with peripheral projections depend on their target for trophic support during a critical period of natural cell death. Much less is known about central systems. That dopaminergic neurons of the substantia nigra may depend on their target, the striatum, during development is suggested by the presence of a natural apoptotic cell(More)
We have previously observed that an axon-sparing lesion of the striatum during development is associated with an induction of apoptotic cell death in the substantia nigra (SN). We have postulated that the induced death is due to a loss of striatum-derived trophic support. In other paradigms of neural development, it is often found that a need for trophic(More)
Butyrivibrio proteoclasticus is a significant component of the microbial population of the rumen of dairy cattle. It is a xylan-degrading organism whose genome encodes a large number of open reading frames annotated as fiber-degrading enzymes. We have determined the three-dimensional structure of Est2A, an acetyl xylan esterase from B. proteoclasticus, at(More)
Of a sample of 42 gram-negative Hg-resistant bacteria, three (a Pseudomonas fluorescens, a Klebsiella sp. and a Citrobacter sp.) contained translocatable elements conferring resistance to Hg2+ (all three) and to Hg2+ and phenylmercuric acetate (P. fluorescens). The discovery of transposable phenylmercuric acetate resistance extends the range of known(More)
1. The major metabolite after incubating aniline with sheep intestine was acetanilide. 2. Other metabolites detected in smaller amounts were 2-aminophenol, 4-aminophenol, 2-acetamidophenol and 4-acetamidophenol. 3. The rumen, abomasum duodenum, jejunum, ileum and colon were all able to acetylate aniline. 4. 4-Aminophenol, 4-aminobenzoic acid, 4-anisidine(More)
