Prostaglandin E1 has earlier been shown to decrease pulmonary platelet trapping (PPT) following shock. This experiment was performed to evaluate a new method to study PPT in vivo, and to study the effect of prostaglandin E1 and a new antiplatelet drug (ticlopidine) on PPT in rabbits after i.v. administration of endotoxin. Following platelet labeling with In-111, the rabbits were placed under a sci

The task of specifying a brake system for a vehicle is without doubt one of the most crucial decisions a design manager must undertake in the development process of a vehicle. Improved vehicle aerodynamics, higher loads, more horsepower and increased road safety all create the need for more effective brake systems. The most dominant of these is the disc brake system, due to the absence of fade and

Social insects such as termites live in colonies in which cooperation is assumed by all individuals developing into castes to which specific tasks are allocated. Little has been reported about molecular aspects underlying termite caste-specific gene expression. Genetic regulation has recently been hypothesized to govern caste-specific traits and physiology in social insects. Cytochrome c oxidase (

The reaction mechanism of propane ammoxidation was studied on an Al-Sb-V-W-oxide catalyst using a TAP-2 reactor system. Analyses of the responses from both high-speed pulse transients with reactants and TPD experiments were performed. Since the ammoxidation process with three reactants proceeds from propane to acrylonitrile over propylene as an intermediate, the experiments comprised oxidation of

1 We examined non-adrenergic, non-cholinergic (NANC) stimulation for its stabilizing effect on bronchial smooth-muscle tone with respect to its regulatory power and the effect of variations in neural impulse frequency. 2 The guinea-pig isolated main bronchus (n = 4-12) was pretreated with indomethacin (1O JAM) and incubated with atropine (1 pM) and guanethidine (10 JM). Electrical field stimulatio

Popular Abstract in Swedish Föreliggande avhandling är en fallstudie vars empiriska material utgörs av kvalitativa forskningsintervjuer, deltagande observationer och textdokument. Avhandlingen uppmärksammar ett händelseförlopp på en nystartad svensk gymnasieskola. Förloppet inleds med kommunens och rektorns stora visioner för verksamheten och avslutas med att en samstämmig lärargrupp avsätter rektThis dissertation is based on a case study of a series of events at a newly started Swedish high school. The study employs a qualitative methodology comprising of interviews, participant observation and analysis of text documents. The series of events opens with the grand visions of the municipality and the school's principal for the school and concludes with the teachers at the school unanimously

The most important issue in this dissertation will be a discussion concerning metal age flint use in Scania. Since flint tools from the Bronze and Iron Ages and Medieval times have rarely been examined, there are few general guidelines in typology or morphology. It is quite clear that conversions of existing Stone Age typological schemes are unsuitable when one intends to study the often simple an

Background. Current evidence suggests that high red meat intake is associated with increased colorectal cancer risk. High fish intake may be associated with a decreased risk, but the existing evidence is less convincing. Methods: We prospectively followed 478040 men and women from 10 European countries who were free of cancer at enrollment between 1992 and 1998. Information on diet and lifestyle w

This thesis summarizes experimental work in which the powerful Ti:sapphire lasers at the High Power Laser Facility at the Lund Laser Centre have been employed to investigate laser-produced X-rays and relativistic channelling. These lasers produce short pulses, of the order of 50 fs, with energies ranging from 1 mJ to 1 J. Thus, the peak powers reach several terawatts and with the most powerful las

Intrinsic permeability of water in beefburgers made of different meat raw materials cooked at 50 degrees C, 60 degrees C, 70 degrees C and 80 'C was measured using an air-driven pressure cell, and it was found to be in the range of 6.8 x 10(-18) m(2) to 1.6 x 10(-16) m(2) for the temperature ranging from 50 degrees C to 80 degrees C. The highest permeability value was found in beefburgers prepared

Popular Abstract in Swedish ETT PARADIS FÖR ALLA. EPA MELLAN FOLKHEM OCH FÖRFÖRELSE I början av 1930-talet etablerades en ny form av konsumtion i Sverige när Enhetsprisaktibolaget Epa öppnade dörrarna för en hänförd och överväldigad allmänhet. Hörnstenar i Epa-systemet var fasta priser, massproducerade produkter, stora lagerutrymmen och låga leveranskostnader. Varorna var avsedda för en ny bred kA Paradise for All. Epa between the People's Home and Seduction. This dissertation is about the Epa department store chain, which existed in Sweden from 1930 to 1977. For many people, Epa was an arena for meeting modernity. By allowing issues of tradition and modernity, cultural learning processes, class, gender and aesthetics to collide with the Epa phenomenon, a complex picture of the Swedish P

A farm systems mass-balance calculation model, FARMFLOW, was applied to a case study comparing organic and conventional management of a Swedish experimental dairy farm, Ojebyn. Parameterisation of the model is implemented using detailed field data from the Ojebyn farm where the two management systems have been run parallel for more than 11 years. Simulations were made to compare the stocks, flows

Severe hypoglycemia was induced by insulin in lightly anaesthetized (70°o N2O) and artificially ventilated rats. Brain tissue was frozen in situ after spontaneous EEG potentials had disappeared for 5. 10. 15 or 30 min and cerebral cortex concentrations of labile organic phosphates, glycolytic metabolites, ammonia and amino acids were determined. In other experiments, recovery was induced by glucos

The aim of this study was to evaluate some bioassays that are different in principle: cell counting, colony forming assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT), sulforhodamine B (SRB), crystal violet, and alamarBlue, with respect to their ability to measure cisplatin-induced cell death of in vitro-cultivated squamous cell carcinoma of the head and neck (SCCHN). Cispl

OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.

Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors difficult. This thesis has applied microarray-based gene expression and copy-number profiling to STS

Objective: To investigate the association between human herpesviruses and multiple sclerosis ( MS), as well as between measles virus and MS. Methods: The authors identified prospectively collected serum samples from 73 MS cases and retrospective sera from 161 MS cases in two population-based serum bank registers. Analyses of IgG antibody responses in cases and matched referents were performed for

Conclusions. The results indicate that SOM of extreme duration, and maybe also the treatment of SOM, are risk factors for developing permanent hearing loss, both conductive and sensorineural. Objective. Fluctuating or persisting hearing loss of varying degrees is known to accompany secretory otitis media ( SOM). The aim of this study was to detect possible hearing sequelae in young adults who had

Allochthonous organic carbon in aquatic systems is metabolized by heterotrophic bacteria, with significant consequences for the biostructure and energy pathways of freshwater ecosystems. The degree to which allochthonous substrates support growth of bacteria is largely dependent on bacterial growth efficiency (BGE), i.e., bacterial production ( BP) per unit of assimilated carbon. Here we show how
