Molecularly imprinted polymers (MIPs) are synthetic materials that mimic the behavior of natural antibodies while exhibiting far greater stability than their natural counterparts. Although potentially very useful as recognition elements in chemical sensors, a major obstacle to their widespread application has been the difficulty in preparing MIPs in the thin-film format that is necessary for coupl
The level of the tissue inhibitor of metalloproteinases 1 (TIMP-1) has previously been demonstrated to predict the survival of early stage colorectal cancer patients. The present study was undertaken to further validate plasma TIMP-1 as a prognostic marker in rectal cancer. Preoperative plasma from 352 rectal cancer patients were analysed using an immunoassay for TIMP-1. The TIMP-1 immunoassay dem
BACKGROUND: Improving human nuclear transfer (NT) efficiencies is paramount for the development of patient-specific stem cell lines, although the opportunities remain limited owing to difficulties in obtaining fresh mature oocytes. METHODS: Therefore, the developmental competence of aged, failed-to-fertilize human oocytes as an alternate cytoplasmic source for NT was assessed and compared with use
This is a popular summary of the authors' thesis entitled "Geographic distribution of intra-specific variation in widespread boreonemoral Eurasian woodland herbs" and "Geographic differentiation and population history in Silene dioica and S. hifacensis: variation in chloroplast DNA and allozymes", respectively, defended in September 2002 and October 2001 at the Department of Systematic Botany, Lun
Particle size distribution (size-range 3-900 nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September-November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration. The total particle number (ToN) and NOx are well correlated at
The present study describes the preparation of 11 batches of starch microspheres for drug delivery. Parameters such as the type of starch material, the type of protein, and the incubation time of the process were varied, and the obtained microspheres differed in yield, encapsulation efficiency and physical properties. The crystalline/ordered structure (obtained through X-ray powder diffraction (XR
The influence of a fire retardant (Firesorb, an acrylic-acrylamide copolymer) on the microbial community structure determined by phospholipid fatty acid (PLFA) analysis was examined under laboratory conditions using two different textured soils under pine forest. Firesorb was added to unheated and heated soil samples (350 degrees C for 10 min followed by reinoculation, to mimic a forest fire) at t
Special purpose service robots have already entered the market and their users homes. Also the idea of the general purpose service robot or personal robot companion is increasingly discussed and investigated. To probe human-robot interaction with a mobile robot in arbitrary domestic settings, we conducted a study in eight different homes. Based on previous results from laboratory studies we identi
To validate a detailed questionnaire for assessment of environmental tobacco smoke (ETS) exposure by the biomarker cotinine in various media, a population-based study in the urban area of Malmo, Sweden was performed in children aged 8-13 years with and without asthmatic symptoms. There were strong correlations between urinary and saliva cotinine concentrations and also, though to a lesser extent,
Fourier transform infrared (FTIR) and extended X-ray absorption fine structure (EXAPS) spectroscopic measurements were performed on Pb(II)ethylenediaminetetraacetic (EDTA) adsorbed on goethite as a function of pH (4-6), Pb(II)EDTA concentration (0.11-72 mu M), and ionic strength (16 mu M-0.5 M). FTIR measurements show no evidence for carboxylate-Fe(III) bonding or protonation of EDTA at Pb:EDTA =
The 2000–2006 achievements in the field of synthesis, property examination, and application of proton-exchange membranes are reviewed on the basis of more than 120 papers.
Insulin receptor substrate-1 (IRS-1) is tyrosine-phosphorylated in response to insulin resulting in association with and activation of phosphatidylinositol 3-kinase (PI 3-kinase), thereby initiating some of the effects of insulin. We have recently shown that the insulin-like effects of growth hormone (GH) in adipocytes can be inhibited by the selective PI 3-kinase inhibitor wortmannin (Ridderstral
For large classes of vorticities we prove that a steady periodic gravity water wave with a monotonic profile between crests and troughs must be symmetric. The analysis uses sharp maximum principles for elliptic partial differential equations.
Nine spouses of people who had suffered from acute leukemia or highly malignant lymphoma were interviewed about their everyday life experiences throughout their partner's illness and treatment, and concerning their view of the professional care provided. The transcribed texts were subjected to phenomenological-hermeneutic analysis. The spouses felt they were in a situation of overall severe crisis
The aim of this study was to evaluate the validity of a questionnaire and medical anamnesis to identify persons with dermatitis in an occupational setting. The design was a clinical epidemiological cross-sectional study. The study was performed between the second and fourth week of January 2001. A questionnaire was followed a week later by a medical occupational interview and a clinical dermatolog
Objectives: Regarding the recent attention to develop policies regarding the provision of clinical genetic testing services, access to, acceptance, utilisation and regulation of genetic services was investigated in selected European countries as well as one non-European country. Methods: Data were collected on the basis of relevant international reports and sources accessible via the internet, fro
This study was performed to investigate the glomerular permeability alterations responsible for the microalbuminuria occurring in endotoxemia and during anaphylactic shock. In anaesthetized Wistar rats, the left ureter was catheterized for urine collection, while simultaneously, blood access was achieved. Endotoxemia was induced by Lipopolysaccharide (LPS) from E. Coli, and glomerular permeability
