This paper describes interpolation procedures for EPR. In principle, interpolation for EPR is simple: It is a special case of first-order interpolation. In practice, we would like procedures that take advantage of properties of EPR: EPR admits finite models and those models are sometimes possible to describe very compactly. Inspired by procedures for propositional logic that use models and core...
The last few years have seen important new advances in EPR which have the possibility of revolutionizing the applications of EPR in chemistry and related fields. New methods include (a) two-dimensional and Fouriertransform EPR; (b) far-infrared EPR (with 1 mm waves); (c) dynamic imaging of diffusion by EPR; (d) powerful computational algorithms for spectral simulation. These new methods and the...
X-band EPR spectra of singlet O2((1)Δg) and triplet O2((3)Σg(-)) were observed in the gas phase under low molecular-oxygen pressures PO2 = 0.175-0.625 Torr, T = 293-323 K. O2((1)Δg) was produced by quenching of photogenerated triplet sensitizers naphthalene C8H10, perdeuterated naphthalene, and perfluoronaphthalene in the gas phase. The EPR spectrum of O2((1)Δg) was also observed under microwav...
Receptor-mediated assembly of blood proteases on vascular cells maintains the hemostatic balance and initiates intracellular signal transduction. Effector cell protease receptor-1 (EPR-1) is an approximately 62-kDa vascular cell membrane receptor for the clotting protease factor Xa, participating in thrombin formation and lymphocyte activation. Here, recombinant EPR-1 fragments were engineered ...
BACKGROUND Chronic obstructive pulmonary disease (COPD) affects > 3 million people in the UK. Acute exacerbations of COPD (AECOPD) are the second most common reason for emergency hospital admission in the UK. Pulmonary rehabilitation is usual care for stable COPD but there is little evidence for early pulmonary rehabilitation (EPR) following AECOPD, either in hospital or immediately post discha...
Erythropoietin-receptor (EpR) expression on bone marrow cells from normal individuals and from patients with chronic myeloid leukemia (CML) was examined by multiparameter flow cytometry after stepwise amplified immunostaining with biotin-labeled Ep, streptavidin-conjugated R-phycoerythrin, and biotinylated monoclonal anti-R-phycoerythrin. This approach allowed the detection of EpR-positive cell...
Ionizing radiation is useful for the conservation and disinfestation of fresh and dried fruits. The treatment of fruits with gamma-rays or beams of accelerated electrons has been carefully tested and was recommended by FAO/WHO Codex Alimentarius Commission for the common use as an effective and safe preservation method [1]. It was found earlier that the ionizing radiation produces stable EPR si...
The results from the EPR studies on wheat and oat bran, rolled oats, buckwheat and different kind of rice – white, brown and parboiled rice before and after gamma-irradiation are reported. Before irradiation all samples exhibit one weak singlet EPR line characterized with common g-factor of 2.00480.0005 and six lines due to Mn naturally available in the plants. Only parboiled rice did not show...
