Comparative analysis of the mouse and human genes (Matn2 and MATN2) for matrilin-2, a filament-forming protein widely distributed in extracellular matrices

We previously identified matrilin-2 (MATN2), the largest member of the novel family of matrilins. These filament-forming adapter proteins expressed in a distinct, but partially overlapping, pattern in all tissues were implicated in the organization of the extracellular matrix. Matrilin-2 functions in a great variety of tissues. Here, we present the genomic organization of the highly conserved mous

Neosordarin and hydroxysordarin, two new antifungal agents from Sordaria araneosa

Two novel antifungal agents belonging to the sordarin family have been isolated from fermentations of Sordaria araneosa by bioassay-guided purification and their structures elucidated by NMR techniques. Neosordarin (1) is closely related to the recently discovered hypoxysordarin (2), with only small differences on the aliphatic side chain acylating the hydroxyl in the 3'-position of the sordarose

Quantum interference between multi photon absorption pathways in organic solid

We demonstrate spatial interference fringe pattern by simultaneous one- and three-photon absorption of UV and near-IR femitosecond pulses in thin film organic solid at room temperature. We use organic dendrimers that are specially designed to have strong fluorescence and very large three-photon absorption cross-section. High fringe visibility allows the quantum interference to be observed by eye.

Smoking as a determinant of the geographical pattern of cardiac events among women in an urban population

Background: Smoking is the major risk factor for cardiac events in younger women and is most common in groups with the least favourable socioeconomic circumstances. Objective: To assess to what extent geographical differences in the female incidence of myocardial infarction in the city of Malmo in Sweden can be accounted for by smoking and to what extent intra-urban variances of smoking are relate

Channel Related Optimization of Wireless Communication Systems

This thesis deals with different optimization problems in the design of wireless communication systems. It is mainly directed to the design of systems based on multicarrier techniques and orthogonal frequency division multiplex, OFDM, but some of the problems apply to single carrier systems as well. The influence of different pilot patterns is analyzed when pilot symbol assisted modulation, PSAM,

Biodegradation of nonylphenol in a continuous packed-bed bioreactor.

A packed bed bioreactor, with 170 ml glass bead carriers and 130 ml medium, was tested for the removal of the endocrine disrupter, nonylphenol, with a Sphingomonas sp. The bioreactor was first continuously fed with medium saturated with nonylphenol in an attempt to simulate groundwater pollution. At best, nonylphenol was degraded by 99.5% at a feeding rate of 69 ml h-1 and a removal rate of 4.3 mg

LEPREL1, a novel ER and Golgi resident member of the Leprecan family.

We have identified a novel protein, Leprecan-like 1 (LEPREL1), with profound similarity to the Leprecan family of proteoglycans. The genomic organization of the Leprecan gene family was found to be highly conserved. Expression analysis shows that LEPREL1 is expressed in most tissues as a 3.4 kb transcript encoding an 80 kDa protein. A LEPREL1 specific antibody stains many cell types including adip

Approximation algorithms for Hamming clustering problems

We study Hamming versions of two classical clustering problems. The Hamming radius p-clustering problem (HRC) for a set S of k binary strings, each of length n, is to find p binary strings of length n that minimize the maximum Hamming distance between a string in S and the closest of the p strings; this minimum value is termed the p-radius of S and is denoted by varrho. The related Hamming diamete

Catalytic decomposition of formic acid on oxide catalysts - III. IOM model approach to bimolecular mechanism

In our previous paper [M.A. Borowiak, M.H. Jamroz, R. Larsson, J. Mol. Catal. A: Chem., 139 (1999) 97], an impulse-oscillation model (IOM) was used for a time description of catalytic acts in the reactions of catalytic decomposition of formic acid on oxide catalysts for unimolecular mechanism. In this paper: the bimolecular mechanism were modelled for the same reactions. The results of IOM calcula

Revaccination with Bacillus Calmette-Guerin (BCG) vaccine does not reduce morbidity from malaria in African children

Abstract in French Donnees de base Des études menées en Arique de l'ouest et ailleurs ont suggeree que le vaccin Bacille Calmette-Guerin (BCG) administréà la naissance était bénéfique pour la survie de l'enfant. Cet effet bénéfique proviendrait en partie de l'effet sur la malaria, une hypothèse supportée par des études sur animal. Nous avons investigué si la revaccination avec le BCG à 19 mois rBACKGROUND: Studies in West Africa and elsewhere have suggested that Bacillus Calmette-Guerin (BCG) vaccine given at birth is beneficial for child survival. It is possible that this effect is mediated partly through an effect on malaria, a hypothesis supported by animal studies. We investigated whether revaccination with BCG at 19 months of age reduced morbidity from malaria. METHOD: In the capita

Synthesis, Structures and Oxo Transfer Reactivity of bis(Dithiolene) Tungsten(IV,VI) Complexes Related to the Active Sites of Tungstoenzymes

A series of bis(dithiolene)tungsten(IV,VI) complexes derived from benzene-1,2-dithiolate (bdt) has been prepared as an synthetic approach to pterin dithiolene-bound active sites of tungstoenzymes, one example of which, a archaeal oxidoreductase, has been established crystallographically (Chan et al. Science 1995, 267, 1463). With [WIVO(bdt)2]2- (2) as the starting compound, silylation with RR'2SiC

The FERRUM Project: New f-value Data for Fe II and Astrophysical Applications

We present the FERRUM Project, an international collaboration aiming at a production and evaluation of oscillator strengths (transition probabilities) of selected spectral lines of singly ionized iron group elements, that are of astrophysical relevance. The results obtained include measurements and calculations of permitted and forbidden lines of Fe II. The data have been applied to both emission
