Dietary supplements, designed to fortify the antioxidant status of human metabolism, are intended to provide nutritional support against the aging process. The strategy is based on the observation that environmental and metabolic sources of oxidatively generated free radicals damage key macromolecules, such as DNA, that in turn alter physiologic processes, and in turn may contribute to aging and a

STUDY DESIGN: By implanting tantalum indicators percutaneously during application of pedicular screws, lumbosacral mobility could be studied with roentgen stereophotogrammetric analysis in seven patients having a diagnostic external fixation test. OBJECTIVES: To determine the mechanical effects on the segmental mobility during an external fixation test of the lumbar spine. SUMMARY OF BACKGROUND DA

PURPOSE: The frequency of activated protein C (APC) resistance, caused by factor V R506Q gene mutation and abnormal APC ratio, in patients with peripheral vascular diseases was analyzed. METHODS: All patients electively admitted to the vascular ward unit of our tertiary care academic medical center from January 1995 through October 1996 (n = 679) were prospectively analyzed using an APC-resistance

It was shown by Southern hybridization that cotton-top tamarin and common marmoset, New World monkeys, carry three or more genes encoding beta-microseminoprotein, also known as PSP94. In contrast, the genomes of Old World monkeys, as represented by rhesus macaque and sacred baboon, contain a single gene. Clones containing three different genes encoding beta-microseminoprotein were isolated from a

"Foreword: The durability of building materials, especially the corrosion of reinforcement in concrete structures, has been a main research area in Scandinavia during the last decades. Results from many laboratories in the Scandinavian countries, and outside of Scandinavia, indicate that there are certain relationships between the service life and different concrete parameters, such as the water/b

Children already have intimal thickenings occupying over half of the vascular lumen. Intimal thickening is one of the first steps in atherogenesis. Classical risk factors such as hypercholesterolaemia, genetic background and acute noxious factors play a role in its development. Genetic origin of the children from high-risk groups for coronary heart disease seems to be a determinant of the magnitud

Finite size effects oil cluster distributions are investigated within Ising and Fisher's Droplet Model. Fixed magnetization calculations suggest that, the introduction of a complement correction of the emitting system is a promising approach for finite size scalings.

The high level of protection required by personal protective clothing (PPC) severely impedes heat exchange by sweat evaporation. As a result work associated with wearing PPC, particularly in hot environments, implies considerable physiological strain and may render workers exhausted in a short time. Recent development of algorithms for describing the heat transfer, accounting for pumping and wind

This paper reports detailed abundance analyses for four extremelymetal-poor (XMP) giant stars with [Fe/H]

A method for the simultaneous determination of hexahydrophthalic acid (HHP acid) and methylhexahydrophthalic acid (MHHP acid) in human plasma was developed. The procedure was a rapid, single step extractive derivatisation with pentafluorobenzyl bromide as the derivatisation agent. The formed pentafluorobenzyl esters were analysed by gas chromatography-mass spectrometry in negative ion chemical ion

Genotyping of Chlamydia trachomatis is limited by the low sequence variation in the genome, and no adequate method is available for analysis of the spread of chlamydial infections in the community. We have developed a multillocus sequence typing (MLST) system based on five target regions and compared it with analysis of ompA, the single gene most extensively used for genotyping. Sequence determina

We extend the recursion formula for matrix Bessel functions, which we obtained previously, to superspace. It is sufficient to do this for the unitary orthosymplectic supergroup. By direct computations, we show that fairly explicit results can be obtained, at least up to dimension 8x8 for the supermatrices. Since we introduce a new technique, we discuss various of its aspects in some detail. (C) 20

This study addresses the problem of foreign policy change. While the 1990s has been characterized by remarkable changes in world affairs, political scientists have been slow to study the processes through which such changes take place. Drawing on the limited research that does exist in this field, the study presents an alternative explanatory model of foreign policy change, arguing that states ten

1. The cutaneous receptive fields of 225 climbing fibres projecting to the forelimb area of the C3 zone in the cerebellar anterior lobe were mapped in the pentobarbitoneanaesthetized cat. Responses in climbing fibres were recorded as complex spikes in Purkinje cells. 2. A detailed topographical organization of the nociceptive climbing fibre input to the C3 zone was found. In the medial C3 zone cli

In this letter, the authors demonstrate a vertical wrap-gated field-effect transistor based on InAs nanowires [Proc. DRC, 2005, p. 157]. The nanowires have a diameter of 80 nm and are grown using selective epitaxy; a matrix of typically 10 x 10 vertically standing wires is used as channel in the transistor. The authors measure current saturation at V-ds = 0.15 V (V-g = 0 V), and a high mobility, c

We study electron spin transport and the spin Hall effect in a quantum waveguide in the presence of Rashba spin-orbit interaction (SOI) and a homogeneous in-plane magnetic field, as well as the energy dispersion relation and spin polarization properties of the electron states in the corresponding infinite system. A general expression for the spin polarization of the outgoing flux, resulting from a

The contribution of different receptor subtypes in the contractile response during cooling in human hand vessels is of considerable interest in the understanding of cold-induced peripheral vasospasm as it appears in Raynaud's phenomenon. Subcutaneous vein segments from 50 patients undergoing hand operations not related to vascular disorders were examined in vitro. The temperature in the organ bath
