Reaction between a mixture of cis-trans-[PtCl2(SMe2)(2)] and 1 eqiv. AsPh3 in chloroform gives Cis-[PtCl2(SMe2)(AsPh3)] crystallizing in P2(1)/n with a = 10.397(2), b = 14.876(3), c = 13.956(3) Angstrom, beta = 90.86(3)degrees and Z = 4. Selected geometrical parameters are Pt-As 2.3531(10), Pt-S 2.262(2), Pt-Cl (trans to S) 2.301(2), Pt-Cl (trans to As) 2.328(2) Angstrom and S-Pt-As 88.85(6), S-Pt

The accuracy and precision of holographic interferometry as a method to measure diffusion coefficients in gels are investigated both experimentally and theoretically. The standard deviations in the experimentally determined diffusion coefficient for ethanol in 4% (w/v) agarose gel were 3.3% for diffusion into the gel and 6.1% for diffusion out of the gel. These are in good agreement with the stand

Eleven monoclonal antibodies (MoAb) directed against the immunoregulatory plasma glycoprotein alpha 1-microglobulin were characterized. The MoAb were produced in mice immunized with a mixture of alpha 1-microglobulin homologues from man, guinea pig, rat and rabbit. Using radioimmunoassay, western blotting, affinity chromatography, and Scatchard analysis, the affinities and binding sites of the MoA

The potential risk for consumers to be exposed to banned azo dyes in leather is strong motivation for the development of an analytical test procedure with improved accuracy. The currently most accepted analytical procedure for this application, the German standard DIN 53316 method, suffers from major drawbacks including low accuracy and the usage of hazardous organic solvents. As a consequence, an

Popular Abstract in Swedish Hjärntumörer är relativt vanligt förekommande och antalet nydiagnostiserade fall per år är i ökande. Vid utredning och uppföljning av patienter med misstänkt eller fastställd hjärntumör spelar bildgivande tekniker en betydande roll, med som förstahands metod magnetisk resonanstomografi (MR). Under det senaste decenniet har MR utvecklats från att framställa bilder på hjäThe aims of the studies were: to evaluate the spatial resolution of fMRI at 3 T by studying fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation as compared

In this paper, we propose a method for the estimation of the fundamental frequency of a periodic waveform based on the shift-invariance property of the sinusoidal signal model known from ESPRIT. An advantage of the proposed method is that the model order and the fundamental frequency can be found jointly and that the method does not depend on the density of the observation noise but rather on it b

Medin amyloid is found in the medial layer of the aorta in almost 100% of the Caucasian population over 50 years of age. The medin fragment is 5.5 kDa and derives from the C2-like domain of the precursor protein lactadherin. We have previously reported immunohistochemical findings showing that medin amyloid co-localizes with elastic fibers of arteries and herein we show that lactadherin also is as

The mechanism for hydrogenation of dimethylmaleate in water using cationic rhodium complexes with water-soluble bi-dentate phosphines has been investigated using kinetics and a novel method for the indirect detection of intermediates in catalytic hydrogenation reactions, whereby a late intermediate was detected. A mechanism is proposed involving fast, irreversible substrate binding followed by a r

The synthesis and characterization of all diastereomers of a linear symmetrically fused tris-Troger's base analogue are described. The diastereomers are unambiguously assigned as syn-anti 1a, anti-anti 1b, and syn-syn 1c isomers, by using X-ray diffraction analysis and NMR spectroscopy. For the first time, the anti-anti and the syn-syn diastereomers of a linear symmetrically fused tris-Troger's ba
