In vertebrates, the sensory neurons of the epibranchial (EB) ganglia transmit somatosensory signals from the periphery to the CNS. These ganglia are formed during embryogenesis by the convergence and condensation of two distinct populations of precursors: placode-derived neuroblasts and neural crest- (NC) derived glial precursors. In addition to the gliogenic crest, chondrogenic NC migrates int...

Proper regulation of microtubule dynamics is essential for cell functions and involves various microtubule-associated proteins (MAPs). Among them, end-binding proteins (EBs) accumulate at microtubule plus ends, whereas structural MAPs bind along the microtubule lattice. Recent data indicate that the structural MAP tau modulates EB subcellular localization in neurons. However, the molecular dete...

Epidermolysis bullosa (EB) encompasses a group of inherited blistering skin disorders classified into three main subtypes of simplex, junctional and dystrophic. In recent years there have been substantial advances in our understanding of the molecular basis of these conditions and in the management of such patients. In spite of this progress, squamous cell carcinoma (SCC) is still a major cause...

We have partially purified and characterized two separate DNA polymerase activities associated with Epstein-Barr virus (EB virus). One activity is present in EB virus producer cell lines but not in nonproducer or negative cell lines. It adheres more strongly to DEAE-cellulose than any host cell enzymes, eluting at 210 to 270 mM potassium phosphate buffer. Further elution from phosphocellulose a...

BACKGROUND Inherited epidermolysis bullosa (EB) comprises a highly heterogeneous group of rare diseases characterized by fragility and blistering of skin and mucous membranes. Clinical features combined with immunofluorescence antigen mapping and/or electron microscopy examination of a skin biopsy allow to define the EB type and subtype. Molecular diagnosis is nowadays feasible in all EB subtyp...

Ethidium bromide (EB) is known to inhibit cleavage of bacterial rRNA precursors by Escherichia coli ribonuclease III, a dsRNA-specific nuclease. The mechanism of EB inhibition of RNase III is not known nor is there information on EB-binding sites in RNase III substrates. We show here that EB is a reversible, apparently competitive inhibitor of RNase III cleavage of small model substrates in vit...

A modification of the test for EB virus/IgM introduced by Schmitz and Scherer (1972) is described. It is simple and gives reproducible results.EB virus/IgM was demonstrated in all but one case of infectious mononucleosis and in students with minor illness shown to have acquired EB virus/IgG recently. Unlike the EB virus/IgG, the IgM disappears within a few months. Although the Paul-Bunnell-Davi...

minimum energy per bit required for communicating through deep sub-micron buses at a given bit rate is solved with an explicit answer. It is also shown that this minimum energy per bit can be achieved using coding techniques. Moreover, a differential coding scheme is proposed that achieves most of the possible energy reduction. The methodology given here also applies to more general communicati...

We study the transmission rate (R) and bit-energy-to-interference ratio (Eb/I0) needed to maintain the desired QoS requirement for a given traffic while maximizing the user capacity in multimedia CDMA networks. Closed form functions among transmission rate, bit error rate (or equivalently Eb/I0), QoS requirements, and traffic characteristics are derived. Based on the dependence between R and Eb...

Numerous investigations have shown that 70-kDa heat shock protein (Hsp70) homologs interact tightly with hydrophobic proteins and functionally assist proteins in membranous organelles and environments. One such protein is the Chlamydia trachomatis Hsp70 that is associated with isolated outer membrane complexes of infectious elementary bodies (EB). Previous observations have indicated that chlam...
