Approaches to molecular imprinting based selectivity in capillary electrochromatography.
The work done during the past decade in order to adapt molecularly imprinted polymers (MIPs) to the capillary format and subsequently use these highly selective matrices for capillary electrochromatography (CEC) are reviewed in this article. MIPs are prepared utilizing a templated polymer synthesis where the template addresses the selectivity of the resulting polymer. These polymers possess bindin
Early rheumatoid arthritis--some social, economical, and psychological aspects
Physical, psychological, and social features were assessed with standardized methods in 84 early RA patients followed prospectively for 2 years. During this time disease activity decreased, and disability evaluated by HAQ remained small. Psychological distress measured by SCL-90 (Symptom Check List) was in general not very pronounced and fairly stable over time. A high pain level at baseline provi
Cell replacement therapy in human neurodegenerative disorders
Clinical studies with intrastriatal transplants of embryonic mesencephalic tissue in patients with Parkinson's disease (PD) provide proof-of-principle for the cell replacement strategy in the diseased human brain. The grafted dopaminergic neurons can reinnervate the denervated striatum, restore regulated dopamine release and movement-related frontal cortical activation, and give rise to significan
Habermas on Foucault. Critical remarks
The relation between the œuvres of Jurgen Habermas and Michel Foucault constitutes an important reference point to several aspects of contemporary social research and philosophical discussion. In this paper I give an account of Habermas's critique of Foucault, a critique which operates on three levels-methodology, empirical descriptions, and political implications. I also make some commentaries on
Recommendation to include methyldibromo glutaronitrile in the European standard patch test series.
On the finiteness of Gröbner bases computation in quotients of the free algebra
We investigate, for quotients of the non-commutative polynomial ring, a property that implies finiteness of Gröbner bases computation, and examine its connection with Noetherianity. We propose a Gröbner bases theory for our factor algebras, of particular interest for one-sided ideals, and show a few applications, e.g. how to compute (one-sided) syzygy modules.
Phylogenetic relationships in Alisma (Alismataceae) based on RAPDs, and sequence data from ITS and trnL
The phylogeny of Alisma (Alismataceae), a genus of approximately nine species of aquatic plants mainly distributed in the Northern Hemisphere, was reconstructed with parsimony analysis on RAPD data and sequences of the nuclear ITS and chloroplast trnL regions, and with MDS on RAPD data. Separate analyses were performed on each data set. Butomus umbellatus was used as outgroup in the analysis of se
Distinctive functions of membrane type 1 matrix-metalloprotease (MT1-MMP or MMP-14) in lung and submandibular gland development are independent of its role in pro-MMP-2 activation
Membrane type 1-matrix metalloprotease (MT1-MMP or MMP-14) is a major activator of pro-MMP-2 and is essential for skeletal development. We show here that it is required for branching morphogenesis of the submandibular gland but not the lung. Instead, in the lung, it is essential for postnatal development of alveolar septae. Lung development in Mmp14-/- mice is arrested at the prealveolar stage wit
Medial Expression of TNF-α and TNF Receptors Precedes the Development of Atherosclerotic Lesions in Apolipoprotein E/LDL Receptor Double Knockout Mice
TNF-α is present in atherosclerotic lesions, activates endothelial adhesion molecule expression, stimulates the release of proinflammatory cytokines and matrix metalloproteinases and promotes smooth muscle cell proliferation and migration. Taken together these observations suggest that TNF-α may be functionally involved in early atherosclerosis development. To further evaluate this hypothesis we c
International politics: Scandinavian Identity Amidst American Hegemony?
International politics is often portrayed as a hegemonic discipline, dominated by US scholarship. Exploring the consequences of recent upheavals in world affairs for international politics research, the article suggests that the end of the cold war has exposed certain weaknesses in the US center which may be turned into advantages for the Scandinavian periphery. Specifically, Scandinavian research
Changes in multi-segmented body movements and EMG activity while standing on firm and foam support surfaces.
Postural control ensures stability during both static posture and locomotion by initiating corrective adjustments in body movement. This is particularly important when the conditions of the support surface change. We investigated the effects of standing on a compliant foam surface using 12 normal subjects (mean age 26 years) in terms of: linear movements at the head, shoulder, hip and knee; EMG ac
Rotifers from a humic coastal lagoon of Rio de Janeiro State, Brazil
A four-year study of species composition of the zooplankton community was conducted at Lagoa Comprida, a coastal lagoon. Forty-two species of rotifers were recorded and illustrated. All rotifer species, except Lecane boettgeri Koste, 1986 and Macrochaetus kostei, Jose de Paggi, Branco & Kozlowsky-Suzuki, 2000, have already been found in other areas of Brazil. Some factors, which probably favor
Estimation of Thermal Networks Using Singular Value Decomposition Method
A model is developed using a thermal network analysis approach. An experimental setup is designed and built to validate the model. The model is based on an inverse thermal network analysis using a singular value decomposition algorithm. The data from the experiments are used to determine the thermal conductances using inverse model's unsteady- and steady-state forms. The model development and expe
Familial association of pancreatic cancer with other malignancies in Swedish families
BACKGROUND: The aim of this study was to characterise the familial association of pancreatic cancer with other malignancies. METHODS: Relative risks (RRs) of pancreatic cancer according to family history of cancer were calculated using the updated Swedish Family-Cancer Database, which includes over 11.5 million individuals. Estimates were based on Poisson regression. RRs of tumours for individuals
Histological analysis of fetal dopamine cell suspension grafts in two patients with Parkinson's disease gives promising results
Detection of C-Reactive Protein Utilizing Magnetic Permeability Detection Based Immunoassays
A new sensing technology platform integrating magnetic permeability detection and a two-site heterogeneous immunoassay in a one-step analysis is described. As a platform model, measurements of C-reactive protein (CRP), a cardiac and inflammation marker, were performed in a rapid (11.5 min) high-sensitivity (hs) procedure with a low detection limit (0.2 mg/L) and accuracy (CV = 11%). The two-site h
Evaluation of satellite based indices for gross primary production estimates in a sparse savanna in the Sudan
One of the more frequently applied methods for integrating controls on primary production through satellite data is the Light Use Efficiency (LUE) approach. Satellite indices such as the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and the Shortwave Infrared Water Stress Index (SIWSI) have previously shown promise as predictors of primary production in several dif
Identification of the minimal glycopeptide core recognized by T cells in a model for rheumatoid arthritis
Collagen induced arthritis (CIA) is a common mouse model for rheumatoid arthritis. Two sets of truncated peptides derived from type II collagen have been prepared and tested for binding to A(q), a MHC-II molecule associated with development of CIA. Binding to A(q) correlated well with predictions from a computer-based model. T-cell hybridomas, obtained in CIA, were also used to study the ability o
