This paper discusses coml)lex s t ructural changes during transfer within a non-destructive transfer framework. Though the description of each individual s t ructural change is not difficult, special provision must be made when they are combined, because interaction between them sometimes causes unexpected problems. Transfer of coordinate structures is also discussed a.q this sometimes necessit...

STUDY OBJECTIVES Determine whether obstructive sleep apnea (OSA) subjects show indications of axonal injury. DESIGN We assessed fiber integrity in OSA and control subjects with diffusion tensor imaging (DTI). We acquired four whole-brain DTI series from each subject. The four series were realigned, and the diffusion tensor calculated at each voxel. Fractional anisotropy (FA), a measure of fib...

Ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides to deoxyribonucleotides. Class I RNRs are composed of two homodimeric proteins, alpha2 and beta2. The class Ia E. coli beta2 contains dinuclear, antiferromagnetically coupled iron centers and one tyrosyl free radical, Y122*/beta2. Y122* acts as a radical initiator in catalysis. Redox-linked conformational changes may acco...

Two approaches for creating a new all-cellulose composite material have been studied: the biosynthesis of compartmentalised bacterial cellulose fibril aggregates and the compression moulding of commercial chemical wood pulps processed with only water. The objective was to study the structural changes during processing and the complexity of relating the mechanical properties of the final biocomp...

1. Portal veins, vena cavae and pulmonary arteries from spontaneously hypertensive (SH) rats were found to undergo medial smooth-muscle hypertrophy when compared with corresponding blood vessels from ageand sex-matched WisterKyoto (WKy) normotensive rats. There was an increase in the density of the mucopolysaccharide and glycoprotein staining in veins, pulmonary arteries vena venorum and ventri...

To minimize radiation damage, crystal structures of biological macromolecules are usually determined after rapid cooling to cryogenic temperatures, some 150-200 K below the normal physiological range. The biological relevance of such structures relies on the assumption that flash-cooling is sufficiently fast to kinetically trap the macromolecule and associated solvent in a room-temperature equi...

Structural Labor Market Changes in France France posted remarkable gains in employment in the second half of the 1990s, suggesting that, beyond cyclical factors, structural unemployment may have changed in the period. We provide a novel methodology to separate structural from cyclical labor market changes and apply it to French household level data from 1990 to 2000. We show that the equilibriu...

This paper generalizes the cointegrated vector autoregressive model of Johansen (1988) to allow for structural changes. Estimation under various hypotheses is made possible by a new estimation technique, that makes it simple to derive a number of interesting likelihood ratio tests. E.g., the test for m structural changes against m+ k structural changes (occurring at fixed points in time), m ∈ N...

background: asthma is the main reason of disability, health resource exploitation and low quality of life for those who are affected. it is estimated that nearly 300 million people in the world are suffering from asthma. studies have identified 18 genomic regions and more than 100 genes associated with asthma. among these candidate genes, il-17f plays a very interesting role in asthma. this stu...

multiple myeloma (mm), is the second most common blood cancer after non-hodgkin’s lymphoma. genetic changes, structural and numerical chromosome anomalies, are involved in pathogenesis of mm, and are among the most important prognostic factors of disease-associated patient survival. micrornas (mirnas) are small 19-22 nucleotide single-stranded rnas involved in important cellular processes. cyto...
