Epsilon-aminocaproic acid (epsilon-ACA) is administered to cardiac surgery patients to reduce blood transfusions. Highly water-soluble drugs, such as epsilon-ACA, often have larger distribution volumes in males than in females. We hypothesized that epsilon-ACA concentrations using this dosing scheme would differ by gender because of differences in body composition and weight-adjusted volumes of...
Transgenic mice carrying and expressing the human CD3 epsilon gene incorporate the corresponding protein product into T cell receptor (TCR)/CD3 complexes on thymocyte and T cell surfaces. The chimeric antigen receptors allow normal T cell development and selection of repertoires in vivo and are able to transduce activation signals in vitro. We have exploited the ability to distinguish mouse (m)...
Saccharomyces cerevisiae DNA polymerase delta (Pol delta) and DNA polymerase epsilon (Pol epsilon) are replicative DNA polymerases at the replication fork. Both enzymes are stimulated by PCNA, although to different levels. To understand why and to explore the interaction with PCNA, we compared Pol delta and Pol epsilon in physical interactions with PCNA and nucleic acids (with or without RPA), ...
Regulatory proteins on muscle filaments are substrates for protein kinase C (PKC) but mechanisms underlying activation and translocation of PKC to this non-membrane compartment are poorly understood. Here we demonstrate that the epsilon isoform of PKC (epsilon-PKC) activated by arachidonic acid (AA) binds reversibly to cardiac myofibrils with an EC(50) of 86 nM. Binding occurred near the Z-line...
We study shortest paths and spanning trees of complex networks with random edge weights. Edges which do not belong to the spanning tree are inactive in a transport process within the network. The introduction of quenched disorder modifies the spanning tree such that some edges are activated and the network diameter is increased. With analytic random-walk mappings and numerical analysis, we find...
Replication of the hepadnavirus genome occurs by reverse transcription of an RNA pregenome and is mediated by the viral polymerase; the polymerase is also required for packaging of the pregenome through interaction with the RNA packaging signal, epsilon. Previous work suggested that reverse transcription of minus-strand DNA initiates within the sequence element DR1 (direct repeat 1) and that di...
Centrosomes nucleate microtubules and serve as poles of the mitotic spindle. Centrioles are a core component of centrosomes and duplicate once per cell cycle. We previously identified epsilon-tubulin as a new member of the tubulin superfamily that localizes asymmetrically to the two centrosomes after duplication. We show that recruitment of epsilon-tubulin to the new centrosome can only occur a...
BACKGROUND Several studies have demonstrated that atherosclerotic complications are the major cause of morbidity and mortality in end-stage renal disease (ESRD) patients on dialysis. The allele epsilon 4 of apolipoprotein E (ApoE) gene has been associated with an increased risk for ischaemic cerebrovascular disease (ICVD) in general populations in recent preliminary cross-sectional studies. M...
Interleukin 4 (IL-4)-induced IgE production coincides with the appearance of the 2.2-kb productive epsilon-mRNA, but is preceded by synthesis of a 1.7-kb epsilon-RNA. Analysis of cDNA copies of the 5' end of this RNA indicated that the 1.7-kb epsilon-RNA is a germline epsilon immunoglobulin heavy chain transcript with an exon mapping 5' to the switch region. Transcription through switch regions...
For a given pseudo-Brewster angle phi(pB) of minimum reflectance |r(p)| of p-polarized light at a dielectric-conductor interface, the second-Brewster angle phi(2B) of minimum reflectance ratio |rho|=|r(p)|/|r(s)| of the p and s polarizations is determined for all possible values of the complex relative dielectric function epsilon that lead to the same phi(pB). The difference phi(2B)-phi(pB) is ...
