Macroporous polyacrylamide gels (MPAAG) with iminodiacetic acid (IDA) functionality were prepared by (i) chemical modification of polyacrylamide gel, (ii) co-polymerization of acrylamide with allyl glycidyl ether (AGE) and N,N' metylene-bis(acrylamide) (MBAAm) followed by coupling IDA ligand or (iii) by copolymerization of acrylamide and MBAAm with functional monomer carrying IDA-functionality (1-
RAT dopamine D2short receptors expressed in CHO cells were characterized by activation of [35S]GTPgammaS binding. There were no significant differences between the maximal effects seen in activation of [35S]GTPgammaS binding caused by dopaminergic agonists, but the effects of 5-HT, 8OH-DPAT and 5-methoxytryptamine amounted to 47 +/- 7%, 43 +/- 5% and 70 +/- 7% of the dopamine effect, respectively.
Objectives. This research was conducted to demonstrate the effectiveness of reflective photoelasticity as an in vivo technique for monitoring the strain/stress distribution in prosthetic devices during function. Methods. Seven subjects were selected for this study and divided into three groups according to the design of the prostheses. The buccal surfaces of the experimental prostheses were coated
For most species, it is currently not known whether individual characteristics and population parameters affecting dispersal distances within the local population are also affecting dispersal of individuals emigrating longer distances. We evaluated this in the great reed warbler Acrocephalus arundinaceus by analysing data of natal dispersal distances within (1) the local hatching area in southern
A variety of pathways for electron and carbon flow in the soil bacterium Bacillus subtilis are differentially expressed depending on whether oxygen is present in the cell environment. This study characterizes the regulation of the respiratory oxidase cytochrome bd and the NADH-linked fermentative lactate dehydrogenase, (LDH). Transcription of the cydABCD operon, encoding cytochrome bd, is highly r
Bacterial endotoxin has been suggested as responsible for the development of subjective symptoms and transient or chronic lung function impairment seen after exposure to organic dusts in cotton mills, poultry houses, swine confinement buildings and saw mills. Animal experiments have demonstrated bronchoalveolar neutrophilia being the most prominent cell response in animals following bacterial lipo
Protein D is a surface-exposed lipoprotein of the gram-negative bacterium Haemophilus influenzae with affinity for human immunoglobulin D myeloma protein. The gene encoding protein D (hpd) in a serotype b strain of H. influenzae was cloned. Escherichia coli carrying the hpd gene bound human myeloma immunoglobulin D. Nucleotide sequence analysis identified an 1,092-bp open reading frame that was mo
OBJECTIVES: When clinical data were initially gathered from the Alaskan Eskimos in the 1950's, diabetes mellitus was noted to be quite rare. The prevalence of diabetes has increased significantly since that time, with rates of 10% reported recently in some Alaska native populations. Our goal was to understand the pathogenesis of diabetes among these groups, with the hypothesis that Alaskan Eskimos
Nuclear and chloroplast microsatellite markers were used to study population structure and gene flow among seven Cretan populations of the Aegean endemic plant species Brassica cretica (Brassicaceae). Both nuclear and chloroplast markers revealed exceptionally high levels of population differentiation (overall FST = 0.628 and 1.000, respectively) and relatively little within-population diversity (
TNP-470, a semisynthetic derivative of fumagillin, is an acknowledged angiogenesis inhibitor, presently undergoing clinical trials. It exerts an anti-proliferative effect directed against endothelial cells. This effect is known to be based on cell cycle inhibition effected by the p53/p21 pathway. We observed short-term toxicity of TNP-470 in the B16F10 murine melanoma cell line in vitro and invest
Objectives: To delineate the use of various drugs particularly pertaining to allergy and upper gastrointestinal problems in relation to hormone status in middle aged women. Methods: An analysis from a population-based study on women born between 1935 and 1945 and lived in the Lund area southern Sweden. Of 10766 women, 6917 provided complete data sets; in turn 5673 were assessed for the use of medi
Abstract in Undetermined Liquid food production often involves continuous processing. This leads to problems in traceability systems due to mixing zones and therefore indistinct batch identities causing difficulties with regard to withdrawals or recalls. This article outlines the possible use of the concept of dynamic simulation to improve the handling of batch identities in continuous production
The Svecofennian orogen in the Fennosandian Shield consists of several Palaeoproterozoic meta-igneous provinces that generally young progressively southwards and westwards. The understanding of the tectonic evolution of these different provinces is linked to the ability to constrain the timing of ductile deformation and metamorphism within them. In the western part of the orogen, in central Sweden
The article reports on a longitudinal study of children placed in a children's home during the first two years of the 1980s. The 26 children placed when younger than 4 years of age and staying more than 4 weeks were followed up 3 and 9 months after leaving the children's home and 5, 10, 15 and 20 years later. The children's family relations, including early attachments and later parental relations
Let A be the realification of the matrix algebra determined by Jordan algebra of hermitian matrices of order three over a complex composition algebra. We define an involutive automorphism on A with a certain action on the triple system obtained from A which give models of simple compact Kantor triple systems. In addition, we give an explicit formula for the canonical trace form and the classificat
Age-associated and degenerative loss of functional integrity in soft tissues develops from effects of cumulative and subtle changes in their extracellular matrix (ECM). The highly ordered tendon ECM provides the tissue with its tensile strength during loading. As age and exercise collude in the high incidence of tendinopathies, we hypothesized that aged tendons fail due to cumulative damage result
Postnatal constriction of the full-term ductus arteriosus produces cell death and remodeling of the ductus wall. Using a bioluminescence imaging technique, we found that after birth, the lamb ductus develops ATP, glucose, and glycogen depletion in addition to hypoxia. In vitro studies showed that cell death correlates best with ATP depletion and is most marked when both glucose and oxygen are seve
The present work demonstrates the possibilities of using macroporous silicon as a substrate for highly sensitive protein chip applications. The formation of 3D porous silicon structures was performed by electrochemical dissolution of monocrystalline silicon. The fabricated macroporous silicon network has a rigid spongelike structure showing high uniformity and mechanical stability. The microfluidi
This longitudinal paper draws on data from a larger ongoing project and examines how students conceive of their opportunities to influence their study environment and how this may be related to their self-efficacy beliefs and their study motivation. Interpretative Phenomenological Analysis (IPA) was used to analyze semi-structured in-depth interviews of 10 students of a Masters Program in Engineer
