To gain further insight into the synthesis and structure of the synovial matrix of joints, we have established cell cultures from synovial specimens and elaborated their production of hyaluronan and proteoglycans. The cultures secreted mainly the small proteoglycan decorin, but also considerable amounts of the related biglycan and the large proteoglycan versican. Only minor amounts of heparan sulf
A capacitive biosensor with polyclonal antibodies raised against human serum albumin (HSA) immobilized on a gold transducer has been developed for continuous measurement of HSA in the μM-range. A mathematical model has been refined to describe integral HSA-binding curves assuming that (i) binding is essentially irreversible under the conditions used, (ii) the signal is scaled as the number of non-
Time-domain Green dyadics for linear, homogeneous, temporally dispersive bi-isotropic media are presented. A complex time-dependent electromagnetic field is introduced. Approximation to the complex field from an electric point dipole in an unbounded bi-isotropic medium with respect to the slowly varying components (second forerunner approximation) is obtained. Numerical examples are presented. Sur
The temperature dependencies of the intensities of the HCl stretching bands of the hydrogen chloride complexes with acetylene and ethylene have been used to obtain estimates of the dissociation enthalpies of the two complexes. Quantum chemical calculations on the Hartree Fock and DFT/B3LYP levels of theory have been combined with experimental data to give estimates of the intensities of the HCl st
The adsorption of whey proteins on modified and unmodified 316 2R stainless steel surfaces was studied by in situ ellipsometry under well-defined flow conditions. The effects of bulk properties, e.g. temperature, pH, protein concentration and flow rate as well as surface modification by ion implantation, sputtering, chemical vapour deposition and silica sol-gel deposition, were investigated. The s
Objectives. To record the occurrence of well-differentiated bladder carcinoma reported as T1 G1 to the Swedish Urinary Bladder Cancer Registry, to review the staging and grading of the carcinomas and to scrutinize the validity of the data on T1 G1 tumours reported to the registry during the period 1997-2000. Material and methods. The primary histopathological diagnoses of 98 cases of well-differen
A simplified method using centrifugation and microcentrifuge tubes instead of filtration to measure bacterial activity using thymidine or leucine incorporation, originally used in aquatic habitats, has been adapted for soil. A final step employing hot NaOH to solubilize macromolecules before adding scintillation fluid was necessary to achieve the same incorporation rates as those in the filtration
Popular Abstract in Swedish Avhandlingen behandlar finita element analys av det kopplade problemet bestående av en akustisk fluid innesluten av en flexibel struktur. Det studerade problemområdet kan också innehålla poröst ljudabsorberande material. Denna analys kan appliceras på flera olika ingenjörsproblem, till exempel vid bestäming av ljud nivån i ett fordon på grund av motorns vibrationer ellThis thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. This type of analysis is applicable to a wide range of engineering problems, for example, studying the interior noise in a ve
A novel gene was identified 52 kb upstream of the gene encoding the protease inhibitor elafin (PI3) on human chromosome 20q12-13.1. The transcript of the new gene, denoted huWAP2, was characterized by rapid amplification of cDNA ends and DNA sequencing. The size is 774 bp and it gives rise to a polypeptide of 111 amino acid residues that is homologous to elafin and similar WAP-type protease inhibi
DELPHI results are presented on the inclusive production of two (K(K) over bar π)(0) states in the mass region 1.2-1.6 GeV/c(2) in hadronic Z decays at LEP I. The measured masses (widths) are 1274 +/- 6 MeV/c(2) (29 +/- 12 MeV/c(2)) and 1426 +/- 6 MeV/c(2) (51 +/- 14 MeV/c(2)), respectively. A partial-wave analysis of the (K(K) over bar π)(0) system shows that the first peak is consistent with the
Aim: A study was undertaken to evaluate the feasibility of functional assessment scales regarding completion rate and ability to document functional changes in geriatric rehabilitation patients. Methods: Five functional assessment scales were implemented, and used on admission and discharge as part of standard care. Results: Of 2,812 patients, 90 patients (3.2%) had no scales administered, 2,330 p
The intratracheal (i.t.) instillation of Sephadex beads into rat induced inflammation and a 30-fold increase in the endothelin-1-like immunoreactivity (ET-1-LI) of broncho-alveolar lavage fluid. The levels were highest 24 h after the instillation and had declined significantly after 48 h. At a dose of 1 mg kg-1 i.t., the glucocorticosteroid budesonide almost abolished this response. Phosphoramidon
Current neuroimaging and neurophysiologic techniques have substantially increased our possibilities to study processes related to various language functions in the intact human brain. Learning to read and write influences the functional organization of the brain. What is universal and what is specific in the languages of the world are important issues. Most studies on healthy bilinguals indicate t
We have performed lifetime measurements in the sequences of2S1/2 and2D3/2 states for the alkali-like 4d10 ns,nd configurations of neutral silver. Selective stepwise excitations from the 4d10 5s2S1/2 ground state were performed using two pulsed dye lasers. Optical transients were recorded and evaluated with regard to the decay time. The lifetime results are compared with those of a theoretical stud
