Intraportal tumour cell (TC) injection activates platelets which release serotonin (5-HT). Thrombocytopenia or 5-HT blockade decrease the hepatic lodgement of the injected TCs. A hypothetical explanation of this is 5-HT inhibition of TC killing by phagocytes (e.g. leukocytes and Kupffer cells). In this study, leukocyte phagocytosis was analysed by a chemiluminescence technique at different 5-HT co

Biosynthesis of the sex pheromone components (Z)-5-dodecenol and (Z,E)-5,7-dodecadienol in Dendrolimus punctatus was studied by topical application of deuterium-labeled fatty acids to pheromone glands and subsequent analysis of fatty acyl groups and pheromone components by gas chromatography-mass spectrometry. Our studies suggest that both (Z)-5-dodecenol and (Z,E)-5,7-dodecadienol can be biosynth

Head injuries in sports have received increased attention during the past decade. As explained in this article, the most recent guidelines for the management of head injuries in sports adopted by the American Academy of Neurology (AAN) have been adapted for the Swedish sports society. The guidelines include a grading scale of head injuries in sports, a sideline evaluation to aid physicians, coache

A brief overview is given of a non-associated plasticity theory developed for soils based on the concept of a characteristic stress state of vanishing incremental dilation, and a calibration procedure using only test data from a standard triaxial test. The capability of the model is illustrated by calibration examples and predictions made for standard triaxial tests at different confining stress l

This is a study of change in ecclesiastical praxis and theological Irgument concerning the death penalty and the condemned in Sweden, seen in an international perspective and as a part of general change in the society. The execution gave an example of both crime and revenge and of repentance and the possibility of a pious death. This examl)le through secularisation came under attack from two sides

Through several decades of research, absolute paleointensity estimates have been obtained from a wide range of rocks with varying ages, covering the last 3.45 Ga years. These paleointensity data are crucial to study the past geodynamo and the geological evolution of the Earth's deep interior. However, paleointensity data are often difficult to interpret, and on-going discussions concerning the pas

The Lyme Borrelia genospecies Borrelia afzelii and B. garinii have previously been isolated using a culture method in Swedish patients with Lyme borreliosis (LB). There are reports suggesting that the genospecies distribution in human tissue specimens as determined by molecular methods is different from that obtained by culture. In the present study, we developed a nested PCR for detection of Lyme

In this article we present the first theoretical study of solvent effects on the rotatory strength tensor. The system chosen is solvated formaldehyde for which only one tensor element is nonvanishing, and the solvent is modeled as a linear, homogeneous, and isotropic dielectric continuum. We present results using both an equilibrium and a nonequilibrium description of the solvent. Four illustrativ

In recent years, outcome assessment following different therapeutic procedures has increasingly focused on the patient's perspective. While traditional measures of outcome, including physical examination and imaging diagnostics of the knee are complementary, patient-relevant questionnaires have become more and more important in determining the value of therapeutic procedures. Therefore, there is a

Background: Patients with possible radiation induced cancer could be used to study if the rate of tumour cell proliferation is related to latency time. Such a finding could help researcher to find time periods when other initiating risk factors operate. Methods: Seventeen women with breast cancer, with a prior history of radiation treatment towards the parts or the whole breast, exclusive of the p

Neutrophil (PMN) deposition in tissues (leukosequestration) after shock may produce local tissue injury from proteases and oxygen intermediaries which are released from sequestered PMNs. We quantified leukosequestration in tissues in burned rats using two methods of analysis: 1), measurement of lung myeloperoxidase (MPO); 2), measurement of radiolabeled PMNs and erythrocytes deposited in multiple

Using 12 empirical studies, including 10 experiments and two case studies, the author's compare. inspection and testing techniques and then derive practical implications. Although the research results were somewhat inconclusive, the authors recommend that practitioners generally use inspections for requirements and design and testing for code. Also, because different defect detection methods find

Objective. To explore whether infravesical outlet obstruction is associated with alterations in calcium activation of detrusor smooth muscle. Material and methods. Outlet obstruction was created by partial ligature of the urethra in female rats. Western blotting was performed using an antibody against the cytoplasmatic region of the alpha(1c) subunit of the L- type Ca2(+) channel. Intracellular ca

Apolipoprotein M (apoM) is a recently discovered human apolipoprotein predominantly present in high-density lipoprotein (HDL) in plasma, exclusively expressed in liver and in kidney. The function of apoM is yet unknown. The human apoM gene is located in the major histocompatibility complex class III region on chromosome 6. Because many genes located in this region are related to the immune respons
