1. The effects of varied levels (25-300 mM) of ionic strength on mechanical properties and ATP hydrolysis rate of chemically skinned guinea-pig taenia coli fibres were investigated. 2. The tension development following activation by calcium (pCa 4 8), and relaxation following removal of calcium (pCa 9), were slower in 25 mm compared to 150 mm ionic strength. In fibres activated by thiophosphorylat
Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. The main contributions consist of four algorithms and three VLSI i
In 14 men with prostatic carcinoma, quantitative scintigraphy of the vertebrae from Th10 to L5 was performed before and 2 weeks and 2 and 6 months after start of treatment with luteinizing hormone-releasing hormone (LH-RH) analogues. Serum prostate-specific antigen (PSA) was also determined. The patients with normal bone scintigram showed no change in gamma camera count rate during the study, but
New radiative lifetimes, measured by time-resolved laser-induced fluorescence spectroscopy, are reported for five Rydberg states of singly ionized ytterbium. Free Yb+ ions were produced in a laser-induced plasma. The experimental results have been compared with HFR calculations, taking core-polarization effects into account, and a good agreement (within 25%) between theory and experiment is observ
Backgrounds and aims: To investigate mortality, determinants of mortality, and time until death among elderly subjects receiving public long-term care. Methods: This study comprises 626 respondents (age: 65-98 years). Data were collected for two cohorts (2001 and 2002). Cox regression analysis was used to identify determinants of mortality. Those who died and those who did not die were compared by
Background: The neonatal lupus syndrome can be present as congenital heart block (CHB) or as neonatal lupus erythematosus (NLE), both seldom passively acquired autoimmune diseases. CHB starts around week 20 of pregnancy and is a lifelong event, whereas NLE is self limiting and usually starts at the 6th week of the child's age - the maximum recorded up to week 20. Case report: An asymptomatic mothe
Transient cerebral ischemia following I to 2 hours of middle cerebral artery occlusion (MCAO) in the rat leads to infarction, which can be diminished by synaptic transmission modulators, implying aberrant cell signaling in the pathogenetic process. The authors report here changes in the levels of tyrosine phosphorylated proteins (PTyr) and calcium calmodulin kinase II (CaMKII) phosphorylation of T
The therapeutic effect of monoclonal antibody (H57-597 MoAb) against T-cell receptor (TCR) alpha beta has been investigated on MOG(35-55)-induced experimental autoimmune encephalomyelitis (EAE), as a model system for T-cell-mediated chronic inflammation in the central nervous system (CNS). Short-term administration of the anti-TCR alpha beta immediately after immunization protected the mice from E
Laminin has been proposed to influence the function of human adrenal cortex. We have studied the distribution of laminin (Ln) chains using immunofluorescence in human fetal and adult adrenal cortex. In the fetal gland Ln alpha2- and alpha5-chains were weakly expressed in the definitive zone, whereas Ln alpha4-, beta1-, and gamma1-chains occurred around vessels. In the adult gland, Ln alpha2-, alph
The present communication reviews reasons to perform rescreening of chlamydia-infected persons. It brings up difficulties to differentiate between relapse and reinfection. Studies on follow-up of chlamydia-positive cases after therapy are reviewed. It also highlights reasons for therapeutic failure, like compliance, pharmacological factors, including poor bioavailability, wrong dose regimens, lack
This article outlines an experimental and numerical study of the long-term interaction between silica fume and Portland cement in low-temperature-cured ceramics such as concrete subjected to air, water and sealed curing. For this purpose about 2000 kg of eight qualities of concrete were studied at 4 different ages, each over a period of 90 months. Half of the concretes contained 10% silica fume. P
The internal structure of composite gels made of responsive microgel particles inserted into a bulk hydrogel (N-isopropylacrylamide microgel particles in a cross-linked dimethylacrylamide matrix) has been investigated from the diffusion behavior of poly(ethylene glycol) (PEG) probes through the network, in the absence of specific interactions between the diffusing molecules and the system. The eff
Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri
In a previous study (van de Weijer 2003), it was shown that it is a relatively uncommon pattern to find two IC within the same monomorphemic word. The main purpose of the present study was to establish whether listeners have implicit knowledge of this aspect of phonological word structure. A lexical decision experiment was carried out in which subjects listened to nonsense words and real words in
Protein composition and mechanical function of intermediate filaments were examined in arteries of different sizes using desmin deficient mice (Des-/-) and their wild-type controls (Des+/+). Using SDS-PAGE gels and Western blots we found a gradient in desmin expression in the arterial tree; the desmin content increased from the elastic artery aorta, via the muscular mesenteric artery to the resist
Ruthenium tris-bipyridine dyes containing oligophenyleneethynylene (OPE) rigid rod linker groups ([Ru(bpy)(3)](2+), [Ru(bpy)(2)bpy-E-Ipa](2+), [Ru(bpy)(2)bpy-E-Ph-E-Ipa](2+), and [Ru(bpy)(2)bpy-E-Bco-E-Ipa](2+), where bpy = 2,2'-bipyridine, E = ethynylene, Ph = p-phenylene, Bco = bicyclo[2.2.2]octylene, and Ipa = isophthalic acid) have been investigated using DFT and TD-DFT calculations to elucida
A new approach to calculating the parameters of resonant states is proposed, which also makes it possible to determine the probabilities of the resonant scattering and capture probabilities at the resonant state. This approach is based on the application of the method of configuration interaction, which was proposed for the first time by Fano for an analysis of field ionization of the helium atom.
