Implanted radiotelemetry has been used for the measurement of cortical electroencephalogram (EEG), locomotor activity, body temperature and cardiovascular parameters. This technique allows high quality data acquisition from freely moving animals with no complications of externalised apparatus. This paper focuses on the methodology for short and long-term monitoring of epileptiform activity by simu
Changes in extractability, amount and size distribution of polymeric proteins in the gluten of doughs during mixing were investigated. Ultracentrifugation was used as a non-destructive method to separate the gluten from the dough. Doughs prepared from commercial flour mixtures of different gluten strengths and mixed for varying periods, were analysed. Proteins were detected using RP- and SE-HPLC.
Persistent coagulation activity after an acute myocardial infarction may increase the risk of reinfarction. We prospectively investigated the effects on plasma coagulation of a low, fixed dose of warfarin in combination with aspirin after myocardial infarction. We also evaluated the influence of coagulation activity on clinical outcome. Plasma samples from 97 patients, randomised to 1.25 mg of war
This study demonstrates a method for studying the effects of ethanol on transcription mediated by activating protein-1 (AP-1). The effects of ethanol on AP-1 activity and on the signaling cascades in this process were investigated by using a reporter gene technique with secreted alkaline phosphatase as the reporter gene coupled to nine DNA AP-1-binding elements. Long-term ethanol exposure (48-72 h
The microscopic properties of few interacting cold fermionic atoms confined in a two-dimensional (2D) harmonic trap are studied by numerical diagonalization. For repulsive interactions, a strong shell structure dominates, with Hund's rule acting at its extreme for the midshell configurations. In the attractive case, odd-even oscillations due to pairing occur simultaneously with deformations in the
Background There has been much debate about the value of screening mammography. Here we update the overview of the Swedish randomised controlled trials on mammography screening up to and including 1996. The Kopparberg part of the Two-County trial was not available for the overview, but the continuation of the Malmo trial (MMST II) has been added. The article also contains basic data from the trial
We reported previously the formation of microtears in an in vivo loaded Flexor Digitorum Profundus (FDP) rabbit tendon with a repetition rate of 60 repetitions per minute and a peak force of 15% of maximum peak tetanic force for 80 cumulative hours. Tear area as a percent of tendon area, tear density (tears/mm(2)), and mean tear size (mu m(2)) were higher in tendons from the loaded limb compared t
Although long-term repopulating hematopoietic stem cells (HSC) can self-renew and expand extensively in vivo, most efforts at expanding HSC in vitro have proved unsuccessful and have frequently resulted in compromised rather than improved HSC grafts. This has triggered the search for the optimal combination of cytokines for HSC expansion. Through such studies, c-kit ligand (KL), flt3 ligand (FL),
A major question in soil ecology is whether soil food webs are regulated by resources or by predators, i.e. bottom-up (donor) or top-down controlled. We tested the hypothesis that meso- and macrofaunal soil predators can regulate fungivore populations and, thereby cause a top-down cascade effect on fungal biomass and decomposition/mineralisation processes in boreal forest soils. The study was perf
During the last few decades, quality assurance has been a central issue in the societies, both in, for example the industrial area and in healthcare. It is a tool to measure the outcomes of product or service provided. A review of the literature during the last 17 years with respect to quality assurance work in psychiatric occupational therapy indicates that few articles have been published in the
This work aims to evaluate the predictive strength of the relative seriality, parallel and Lyman-Kutcher-Burman (LKB) normal tissue complication probability (NTCP) models regarding the incidence of radiation pneumonitis (RP), in a group of patients following lung cancer radiotherapy and also to examine their correlation with pulmonary function tests (PFTs). The study was based on 47 patients who r
BackgroundCells from primary Sjögren's syndrome (SS) patients have been reported to show alterations in DNA repair and p53 expression. The DNA-dependent protein kinase (DNA-PK) autoantigen may be involved in both of these alterations in relation to cellular DNA damage responses. We conducted this study of cell-cycle kinetics and p53 to find additional evidence for an abnormal stress response role
The performance of the Hartree-Fock method and the three density functionals B3LYP, PBE0, and CAM-B3LYP is compared to results based on the coupled cluster singles and doubles model in predictions of the solvatochromic effects on the vertical n-->pi(*) and pi-->pi(*) electronic excitation energies of acrolein. All electronic structure methods employed the same solvent model, which is based on the
Since the 1960s, physicians have been aware of electrocardiographic (ECG) abnormalities and cases of sudden death associated with the use of antipsychotic drugs in patients with schizophrenia. Explanations for Such deaths have traditionally focused on drug-induced prolongation of the QT interval leading to the development of life-threatening ventricular arrhythmias such as torsade de pointes (TdP)
The infrared spectrum of the complex between o-H-2 and H2O, D2O, or HDO, isolated in a matrix of solid p-H-2, has been studied between 20 and 4500 cm(-1). In addition the infrared spectrum of the complex between p-D-2 and H2O in solid o-D-2 has been studied. The spectral shifts are interpreted as the result of the quadrupole-dipole interaction between hydrogen and water. (c) 2006 American Institut
The dentate gyrus (DG) is one of the few regions in the brain that continues to produce new neurons throughout adulthood. Seizures not only increase neurogenesis, but also lead to death of DG neurons. We investigated the relationship between cell death and neurogenesis following seizures in the DG of adult rats by blocking caspases, which are key components of apoptotic cell death. Multiple intrac
Most filamentous bacteria in biological nutrient removal (BNR) processes have not been identified beyond their morphotype and simple staining reactions. Furthermore, the majority of sludge filaments observed under the microscope do not hybridize to commonly used phylogenetic probes for well characterized bacterial phyla such as the Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes.
