The subject of our talk is the correct evaluation of interval extension of the function specified by the expression x. Despite the fact that the algorithms which calculate interval extensions of the basic mathematical functions are well known (the algorithms which do the arithmetic operations on intervals are even patented in the USA), at present, there is no systematic approach to evaluation o...
BACKGROUND In the last three decades, the Baculovirus expression vector system (BEV) has evolved to one of the most widely used eukaryotic systems for heterologous protein expression including approved vaccines and therapies. Despite the significant improvements introduced during the past years, the BEV system still has major drawbacks, primarily the time required to generate recombinant virus ...
Genome-wide association studies are likely to be conducted in large scale in the near future. In such studies, searching over hundreds of thousands of markers for the few ones that are associated with disease brings out the multiple-hypothesis testing problem in its severe form. We explore, in a two-stage design, how the use of false discovery rate (FDR) can alleviate the burden of a prohibitiv...
Elimination of the costimulatory molecule B7-2 prevents autoimmune diabetes in NOD mice, but leads to the development of a spontaneous autoimmune polyneuropathy (SAP), which resembles the human disease chronic inflammatory demyelinating polyneuropathy (CIDP). In this study, we examined the immunopathogenic mechanisms in this model, including identification of SAP Ags. We found that B7-2-deficie...
Mice were immunized against chick ribosomes with the use of various protocols and immunogen preparations. Hybridomas were prepared, clones screened, and specific antibodies identified by reversible protein staining followed by immunoperoxidase staining on nitrocellulose blots. Clones were obtained which secreted specific antibodies against ribosomal proteins S6, L7, L18a, P1/P2, and also agains...
The temporal sequence of axon-Schwann cell interaction during regeneration is examined in cat tibial nerves surgically denervated for 8 weeks and, subsequently, coated to a freshly severed peroneal nerve for 3 weeks. Prior to association with regenerating axons, Schwann cells resident in denervated and reinnervated stumps failed to synthesize proteins co-migrant with P0, P1, and P2 myelin prote...
The pathogenesis of peripheral neuropathies in adults is linked to maintenance mechanisms that are not well understood. Here, we elucidate a novel critical maintenance mechanism for Schwann cell (SC)-axon interaction. Using mouse genetics, ablation of the transcriptional regulators histone deacetylases 1 and 2 (HDAC1/2) in adult SCs severely affected paranodal and nodal integrity and led to dem...
We study conditions for the detection of an N -length iid sequence with unknown pmf p1, among M N -length iid sequences with unknown pmf p0. We show how the quantity M2−N D(p1||p0) determines the asymptotic probability of error.
The interactions between bovine pancreatic ribonuclease A (RNase A) and its RNA substrate extend beyond the scissile P-O5' bond. Enzymic subsites interact with the bases and phosphoryl groups of the bound substrate. Those residues interacting with the phosphoryl group comprise the P0, P1, and P2 subsites, with the scissile bond residing in the P1 subsite. Here, the function of the P0 and P2 sub...
During investigations on the regulation of the Pax-6 gene, we characterized a cDNA from quail neuroretina showing a 5' untranslated region distinct from that previously described and initiated from an internal promoter. Using RNase protection and primer extension mapping, we localized this second quail Pax-6 promoter, termed P1. As reported for the already described P0 promoter, P1 was also tra...
