The hypothesis tested is that a 24-h pre-irradiation-exposure of peripheral blood lymphocytes (PBL) to the benzene metabolite hydroquinone (HQ), at doses that are non-acutely toxic (5 microM), induces a less efficient G2-M-checkpoint and enhances the G2-chromosomal radiosensitivity in a statistically significant manner (p<0.01). A less efficient G2-M-checkpoint may allow the transition of damag...

To improve the hydroquinone (HQ) determination limit in wastewater and contribute to the comprehensive utilization of lignin, a zinc oxide-loaded lignin-based carbon fiber (ZCF) was prepared by a combination of electrospinning and thermal treatment processes, and was applied in electrocatalytic oxidation of HQ using cyclic voltammetry (CV). The characterization of composites was conducted by X-...

Four mature rumen and abomasal cannulated wethers were used in a 2 x 2 reversal experiment to study the effect of forage quality on daily quantity of abomasal protein and microbial protein synthesis. Diets were either high quality [HOo 16.4% crude protein (CP)] or low quality (LOo 9.3% CP) Coastal bermudagrass which provided 110.7 and 58.3 g CP intake daily, respectively. Non-ammonia CP reachin...

Reactions of [(η(6)-cymene)Ru(μ-Cl)Cl]2 with acylpyrazolone ligands HQ' (HQ' in general; in detail, HQ(CH2Cl) = 2-chloro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone), HQ(hex) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)heptan-1-one), HQ(nPe) = 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)-3,3-dimethylbutan-1-one)), in the presence of base, gave the corresponding [(η(6)-cymene...

It is shown that there exists an isomorphism between q-oscillator systems covariant under SUq(n) and SUq−1(n). By the isomorphism, the defining relations of SUq−1(n) covariant q-oscillator system are transmuted into those of SUq(n). It is also shown that the similar isomorphism exists for the system of q-oscillators covariant under the quantum supergroup SUq(n/m). Furthermore the cases of q-def...

OBJECTIVES We sought to assess hydroquinidine (HQ) efficacy in selected patients with Brugada syndrome (BrS). BACKGROUND Management of asymptomatic patients with BrS and inducible arrhythmias remains a key issue. Effectiveness of class Ia antiarrhythmic drugs, which inhibit the potassium transient outward current of the action potential, has been suggested in BrS. METHODS From a cohort of 1...

PURPOSE To detail, by DNA microarrays and cellular structure labeling, the in vitro responses of retinal pigment epithelial (RPE) cells to a nonlethal dose of the oxidant agent hydroquinone (HQ). METHODS The viability of growth-quiescent ARPE-19 cells after treatment with HQ was measured by XTT conversion, (3)H-leucine incorporation, trypan blue exclusion, and the presence of DNA laddering. T...

We consider a compact complex manifold M and introduce the notion of two holomorphic Banach bundles E, F over M being compact perturbations of one another. Given two such bundles we show that if the cohomology groups Hq(M,E) are finite dimensional, then so are the cohomology groups Hq(M,F ); as well as a more precise result in the same spirit.

Abstract. We address the minimization of penalized least squares (PLS) criteria customarily used for edge-preserving restoration and reconstruction of signals and images. The minimization of PLS criteria can be addressed using a half-quadratic (HQ) scheme, according either to Geman & Reynolds (1992) or to Geman & Yang (1995) constructions. In the case of large-scale problems, the cost of the HQ...

The algebraic structure of Thermo Field Dynamics lies in the q-deformation of the algebra of creation and annihilation operators. Doubling of the degrees of freedom, tilde-conjugation rules, and Bogoliubov transformation for bosons and fermions are recognized as algebraic properties of hq(1) and of hq(1|1), respectively.
