The idea of applying extracorporeal immunoadsorption (ECIA) in radioimmunodiagnosis and radioimmunotherapy has been proposed previously. The authors here report on the development of new concept using a general method for ECIA based on biotinylated MoAb adsorbed on an avidin column. Athymic rats heterotransplanted with either human melanomas or human lung carcinoma were injected with iodine-125-la
Objective. The phenotypic complexity, together with the multifarious nature of the so-called schizophrenic psychoses, limits our ability to form a simple and logical biologically based hypothesis for the disease group. Biological markers are defined as biochemical, physiological or anatomical traits that are specific to particular conditions. An important aim of biomarker discovery is the detectio
Conformational disorder of conjugated polymers is an important issue to be understood and quantified. In this paper we present a new method to assess the chain conformation of conjugated polymers based on measurements of intrachain energy transfer. The chain conformation is modeled on the basis of monomer-monomer interactions, such as torsion, bending, and stretching of the connecting bond. The la
Migratory birds use multiple sources of compass information for orientation, including the geomagnetic field, the sun, skylight polarization patterns and star patterns. In this paper we review the results of cue-conflict experiments designed to determine the relative importance of the different compass mechanisms, and how directional information from these compass mechanisms is integrated. We focu
Considering the frequent use of mobile phones, we have directed attention to possible implications on cognitive functions. In this study we investigated in a rat model the long-term effects of protracted exposure to Global System for Mobile Communication-900 MHz (GSM-900) radiation. Out of a total of 56 rats, 32 were exposed for 2 h each week for 55 weeks to radio-frequency electromagnetic radiati
Background Treatment of relapsing-remitting multiple sclerosis with interferon beta is only partly effective, and new more effective and safe strategies are needed. Our aim was to assess the efficacy of oral methylprednisolone as an add-on therapy to subcutaneous interferon beta-1a to reduce the yearly relapse rate in patients with relapsing-remitting multiple sclerosis. Methods NORMIMS (NORdic tr
This paper describes an architecture of a connected-cluster labeling algorithm for binary images based on contour tracing with feature extraction. The implementation is intended as a hardware accelerator in a self contained real-time digital surveillance system. The algorithm has lower memory requirements compared to other labeling techniques and can guarantee labeling of a predefined number of cl
Rhizoplaca Zopf is a genus characterized by an umbilicate thallus with an upper and a lower cortex, as well as a cupulate hypothecium. It has been considered to be related to Lecanora Ach., the type genus of the Lecanoraceae and, in particular, to the lobate species of this genus. The phylogeny of Rhizoplaca, the monotypic Arctopeltis thuleana Poelt, and a number of representatives of different gr
We have recently reported that a polymorphism in the cell division cycle (CDC2) gene, designated Ex6 + 7I/D, is associated with Alzheimer's disease (AD). The CDC2 gene is located on chromosome 10q21.1 close to the marker D10S1225 linked to AD. Active cdc2 accumulates in neurons containing neurofibrillary tangles (NFT), a process that can precede the formation of NFT. Therefore, CDC2 is a promising
Objective. To examine whether there is an association between country of birth in first-generation immigrants and first hospitalization for a rheumatic disease, and to study whether any such association remains in second-generation immigrants. Methods. In this followup study, the Swedish MigMed database at the Karolinska Institute in Stockholm was used to identify all primary hospital diagnoses of
Purpose. To compare health-related quality of life (HRQL) and-pain symptoms in patients with PD with a matched control group. To our knowledge, controlled studies of Parkinson's disease (PD) patients within this area are rare. Scope. Fifty-seven patients and 95 controls took part in a self-administered questionnaire study. The instruments were the SF-36, visual analogue scales, pain drawing and pa
We would like to report a case of cerebral infarction associated with anti-cardiolipin syndrome occurring 8 years after cessation of successful treatment of acute lymphoblastic leukemia and 11 years after cranial irradiation.
A new method is presented for monitoring the conformational stability of various parts of a protein that is physically adsorbed onto nanometer-sized silica particles. The method employs hydrogen/deuterium (H/D) exchange of amide hydrogens, a process that is extremely sensitive to structural features of proteins. The resulting mass increase is analyzed with Fourier transform ion cyclotron resonance
BACKGROUND: Serum creatinine is the most commonly used marker for estimation of glomerular filtration rate (GFR). To compensate for its drawbacks as a GFR marker, several prediction equations including several parameters are being used, with the Modification of Diet in Renal Disease (MDRD), Schwartz, and Counahan-Barratt equations being the ones most widely accepted for estimation of relative GFR

A study relating the properties of haematite (alpha-Fe2O3) produced by thermal oxidation of pyrite and marcasite (both FeS2) in air for 1 h at temperatures between 200 and 650 degreesC, to the iron disulphide polymorph and grain size of the sample is reported. Comparisons feature crystallite sizes of haematite from pyrite and marcasite oxidation, and the 125-250 and 710-1000 mum fractions. The cry
Objective Primary hyperparathyroidism (PHPT) is associated with heart disease. The aims of the present study were to evaluate how cardiac function and secretion of N-terminal pro-B-type natriuretic peptide (NT-proBNP) correlate in patients with mild PHPT, and how the plasma level of NT-proBNP is influenced by cure of the parathyroid disease. Design and patients Forty-two patients with PHPT without
