Peripheral blood lymphocytes from 10 nonallergic donors and 7 patients suffering from seasonal allergic rhinitis and receiving desensitization therapy were analyzed by rosette assays for Fc receptors for IgE (Fc epsilon R) and IgG (Fc gamma R) before, during and after the grass pollen season. Six of seven patients had moderately elevated IgE levels (330 +/- 268 IU/ml), all had high titers of sk...

We study the spatial autocorrelation of energy eigenfunctions psi(n)(q) corresponding to classically chaotic systems in the semiclassical regime. Our analysis is based on the Weyl-Wigner formalism for the spectral average C(epsilon)(q(+),q(-),E) of psi(n)(q(+))psi(*)(n)(q(-)), defined as the average over eigenstates within an energy window epsilon centered at E. In this framework C(epsilon) is ...

We describe the genetic and kinetic defects for a low-affinity fast channel disease of the acetylcholine receptor (AChR) that causes a myasthenic syndrome. In two unrelated patients with very small miniature end plate (EP) potentials, but with normal EP AChR density and normal EP ultrastructure, patch-clamp studies demonstrated infrequent AChR channel events, diminished channel reopenings durin...

background and objectives: clostridium perfringens, a gram-positive obligate anaerobic bacterium, is able to form resistant spores which are widely distributed in the environment. c. perfringens is subdivided into five types a to e based on its four major alpha, beta, epsilon and iota toxins. the aim of the present study was cloning and expression of c. perfringens type d vaccine strain epsilon...

The Fc region of immunoglobulin E (IgE) comprising the C epsilon 3 and C epsilon 4 domains (residues 329-547) is sufficient for binding to the high-affinity IgE Fc receptor (Fc epsilon RI alpha). Three potential N-linked glycosylation sites are present within the C epsilon 3 domain. To determine the effect of the glycosylation sites on IgE Fc synthesis and on Fc epsilon RI alpha binding, site-d...

In this paper we consider an exactly solvable model that displays glassy behavior at zero temperature due to entropic barriers. The new ingredient of the model is the existence of different energy scales or modes associated with different relaxational time scales. Low-temperature relaxation takes place by partial equilibration of successive lower-energy modes. An adiabatic scaling solution, def...

A new in vivo method was used to determine an average volumetric elastic modulus ([epsilon]ave) for nongrowing cells in plant tissue. This method requires that both the relative transpiration rate, T, of the tissue and the average turgor pressure decay rate, (dP/dt)ave, of the cells are measured after the water source is removed from the plant tissue. Then [epsilon]ave is calculated from the eq...

We analyzed blood samples from 407 healthy Swedish individuals, 244 men and 163 women, ages 17 to 86 years, for apolipoprotein (apo) E isoforms and serum triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol. Parallel genotyping by means of polymerase chain reaction (PCR)-amplified DNA was performed in 200 subjects. Identical results were obtained b...

For any $\epsilon>0$, Laue and Matijevic [CCCG'07, IPL'08] give a PTAS for finding $(1+\epsilon)$-approximate solution to the $k$-hop MST problem in Euclidean plane that runs time $(n/\epsilon)^{O(k/\epsilon)}$. In this paper, we present an algorithm $(n/\epsilon)^{O(\log k \cdot(1/\epsilon)^2\cdot\log^2(1/\epsilon))}$. This gives improvement on dependency $k$ exponent, while having worse $\eps...

BACKGROUND Epsilon-aminocaproic acid (epsilon-ACA), an antifibrinolytic agent, is used in cardiac surgery to decrease postoperative bleeding. Theoretical concerns exist about the potential for epsilon-ACA to contribute to thrombotic complications. For this reason epsilon-ACA administration is sometimes delayed until after heparinization. This study investigated the impact of the timing of epsil...
