Patients with cervical root compression were used as a "model" to investigate the possible importance of neck disorders and cervical sensory information in postural control. We assessed postural performance with posturography before and after treatment in 71 consecutive patients with MRI-verified cervical root compression without medullary compression. The patients were randomized to surgery (n =
Galectins are implicated in a large variety of biological functions, many of which depend on their carbohydrate-binding ability. Fifteen members of the family have been identified in vertebrates based on binding to galactose (Gal) that is mediated by one or two, evolutionarily conserved, carbohydrate-recognition domains (CRDs). Variations in glycan structures expressed on glycoconjugates at the ce
A supermacroporous cryogel bioreactor has been developed to culture hybridoma cells for long-term continuous production of monoclonal antibodies (mAb). Hybridoma clone M2139, secreting antibodies against J1 epitope (GERGAAGIAGPK; amino acids, 551-564) of collagen type II, are immobilized in the porous bed matrix of a cryogel column (10 mL bed volume). The cells got attached to the matrix within 48
Study Design. Biomechanical analysis of the movement of the lumbar spinal nerve roots (NRs). Objectives. The characteristics of the movement of lumbar spinal NRs corresponding to the change of posture were three-dimensionally analyzed in nonsimulated and simulated adhesion conditions using a porcine model. Summary of Background Data. There is a paucity of data on the movement of NRs. Materials and
En förutsättning för insjuknande i cervixcancer är en infektion med genitalt papillomvirus - HPV. Sjukdomen uppstår efter åratal av förstadier, som kan upptäckas genom cervixcytologi/gynekologisk cellprovstagning och stoppas med behandling. I Sverige har cellprovstagningen minskat förekomsten av livmoderhalscancer med 50 procent. I Finland, där man använder organiserad screening, har förekomsten
Endothelial activation is an important step in atherogenesis. In addition to established cardiovascular risk factors, such as hypercholesterolemia, hypertension, diabetes mellitus, and homocysteinemia, high plasma levels of triglyceride-rich lipoproteins may be an important cause of endothelial activation as well. Free fatty acids hydrolyzed from core triglycerides of these particles can exert bot
We have observed and investigated random telegraph noise in the photoluminescence (PL) from small InP quantum dots (QDs) in GaInP. Very few of the QDs exhibit switching between two states, which have similar total intensities, but distinctly different spectra. Usually, one of the states dominates at low excitation power and the other at high excitation power. The switching occurs on the time scale
Variation in transpiration and conductance between individual trees of Scots pine and Norway spruce was investigated in a mixed 50-year-old stand in central Sweden. Daily transpiration rates were measured by the tissue heat balance method on five trees of each species during a dry, warm growing season. Daytime averages of sapflow, climatic variables and soil water content were used to fit an empir
This article outlines an experimental and numerical study of moisture in concrete subjected to air, water or sealed curing. For this purpose columns of eight qualities of concrete were studied at 3 different ages each over a period of 450 days. Parallel studies of hydration, internal relative humidity, self-desiccation and strength were carried out. Finally the article presents an analysis of the
PURPOSE: To study endovascular graft attachment with self-expanding Gianturco Z-stents and balloon-expanded Palmaz stents and the effect of these devices on the renal ostia. METHODS: Ten stent-grafts were constructed, 5 with Gianturco Z-stents and 5 with Palmaz stents. The endografts were implanted under fluoroscopic guidance into the abdominal aorta of 10 pigs so that the uncovered portion of the
Recently, it has been suggested that at least somekinds of mental representation are strongly context-dependent. Not only what is represented, but also how, depends on the context and the subject's interaction with it. Theories about situated cognition stress the importance of the subject's bodily presence and physical activity in the environment for representing and thinking. What does this mean
Purpose: We report tong-term effects of vagus nerve stimulation (VNS) on epileptiform activity in 15 children, and how these changes are related to activity stage and to clinical effects on seizure reduction, seizure severity (NHS3) and quality of life (QOL). Methods: Initially, and after 3 and 9 months of VNS-treatment, 15 children were investigated with 24 h ambulatory EEG monitoring for spike d
The influence of experimental errors on the determination of flux control coefficients from transient metabolite concentrations with the method proposed by Delgado and Liao [(1992) Biochem. J. 282, 919-927] has been investigated by using Monte Carlo simulations. The method requires least-squares fitting of the transient metabolite concentrations. Three different fitting methods have been evaluated
The level crossing method has been used for the investigation of the hyperfine structure of the 6p2P3/2 and 7p2P3/2 levels of the isotopes Cs133, Cs135, and Cs137. For the hyperfine coupling constants a and b and for the lifetimes ? we find: a(6p Cs133)=50.72(3) gJ/-1.345, b(6p Cs133)=-0.38(18) gJ/-1.345 a(7p Cs133)=16.610(6) gJ/-1.3349, b(7p Cs133)=-0.15(3) gJ/-1.3349 a(6p Cs135)=53.64(4) gJ/-1.3
We present an ab initio study of the n --> pi(*) electronic excitation energy together with the corresponding oscillator strength and rotatory strength tensor for two optically active cyclopropanone related structures: S,S-dimethylcyclopropanone and R,R-t-butylcyclopropanone. We discuss and compare the available experimental data for the n --> pi(*) electronic excitation energy and rotatory streng
The number-size distribution and hygroscopic growth of submicrometer aerosol particles were measured in central Amazonia during the first Cooperative LBA Airborne Regional Experiment (CLAIRE) wet season experiment in March-April 1998. This was the first time ever that these types of measurements were performed in the Amazon rain forest. A Differential Mobility Particle Sizer (DMPS) was used to mea
