S100B serum level predicts computed tomography findings after minor head injury

Background: Mild head injury (MHI) implies a risk for traumatic brain injury and even a small risk for development of an intracranial hematoma. Head computed tomography (CT) is recommended for early detection of such pathologic findings. The present multicenter study was performed to investigate whether determination of protein S100B in serum could contribute to the selection of patients for CT sc

Manual till datorprogrammet GASOL

Gasol är ett användarvänligt PC-baserat datorprogram i Windowsmiljö. Programmet är specifikt utformat för simuleringar av utsläpp av gasol. Gasol är utvecklat på Brandteknik vid Lunds Universitet på uppdrag av Statens Räddningsverk. Gasol är ett vanligt bränsle i Sverige och användningen ökar. Både större och mindre olyckor har inträffat efter vådautsläpp av gasol. För att göra erforderliga riskan

Evidence for superdeformation in Dy-149,Dy-150: Onset of the collapse of the Z=66 deformed shell closure?

An experiment has been performed to search for superdeformed (SD) states in Dy-149,Dy-150. While no evidence for discrete superdeformed states has been observed, a superdeformed ridge with a separation of Delta E-gamma=52 keV with a total intensity of 1.8+/-0.5% that of Dy-150 has been observed. An upper limit of 0.8% (0.9%), of the intensity of Dy-150 (Dy-149), is placed for observation of the mo

Shell Age Economics : Marine Gathering in the Kingdom of Tonga, Polynesia

Popular Abstract in Swedish Denna studie är inriktad på förhållandet mellan människa och hav på Tongaöarna i Polynesien. Särskild tonvikt läggs på det samlande av alger och ryggradslösa djur som utförs av kvinnorna i lagunerna och på korallreven. Beskrivningar ges av hur dessa organismer anskaffas och hur de används för olika ändamål, den plats de haft i religiösa föreställningar samt hur folkökniThis monograph analyses marine gathering in the Polynesian Kingdom of Tonga from ecological, social and cognitive perspectives. The overarching issues explored are (1) the significance of marine gathering in the past and present, (2) how seaweeds and marine invertebrates have been perceived, classified, named and used, (3) how they have been implicated in social relations, and (4) how the integrat

Expression of osteopontin (Eta-1) in Crohn disease of the terminal ileum

Background: The causes of Crohn disease (CD) are still regarded as unknown, but impaired mucosal immunoregulation with activation of T-helper-1 (Th-1) cytokine responses is probably involved and may contribute to the morphological changes. We investigated a possible role of osteopontin (Opn) in the pathogenesis of CD. This glycoprotein has been suggested to be involved in the generation of Th-1-ty

Generating highly polarized nuclear spins in solution using dynamic nuclear polarization

A method to generate strongly polarized nuclear spins in solution has been developed, using Dynamic Nuclear Polarization (DNP) at a temperature of 1.2 K, and at a field of 3.354 T, corresponding to an electron spin resonance frequency of 94 GHz. Trityl radicals are used to directly polarize C-13 and other low-gamma nuclei. Subsequent to the DNP process, the solid sample is dissolved rapidly with a

Superdeformed Bands in 80Sr and the Evolution of Deformation in Sr Isotopes

Four superdeformed bands are reported in Sr-80, extending known superdeformation in the Sr-38 series down to N = 42. The characteristics of these bands are discussed. Residual Doppler shifts were measured and average transition quadrupole moments (Q(t)) inferred for these new bands, These Q(t) values are compared to Q(t) values obtained for previously identified superdeformed bands in Sr81-83. The

Contractile and metabolic characteristics of creatine-depleted vascular smooth muscle of the rat portal vein

The functional consequences of phosphocreatine (PCr) depletion for mechanical properties, O2 consumption, and lactate production of the rat portal vein were investigated. After feeding rats for 8-9 weeks on a diet containing 2% beta-guanidino propionic acid (BGPA), PCr of the portal vein was reduced to 14% of control, whereas ATP was unchanged. No significant change was found in the level of spont

A qualitative study of the experiences during radiotherapy of Swedish patients suffering from lung cancer.

Purpose/Objectives: To describe experiences during radiotherapy of patients suffering from lung cancer. Design: Inductive, qualitative. Setting: A radiotherapy department in the south of Sweden. Sample: 15 patients with lung cancer undergoing their second week of radiotherapy. Methodologic Approach: Interviews were conducted in a hospital setting, transcribed, and content analyzed. Main Research V

Galectin-4 in normal tissues and cancer

Galectin-4 belongs to a subfamily of galectins composed of two carbohydrate recognition domains within the same peptide chain. The two domains have all the conserved galectin signature amino acids, but their overall sequences are only approximately 40% identical. Both domains bind lactose with a similar affinity as other galectins, but their respective preferences for other disaccharides, and larg

Redox hydrogel-based bienzyme microelectrodes for amperometric monitoring of L-glutamate

Fabrication and characterization of amperometric bienzyme L-glutamate sensitive microelectrodes are the prerequisite for monitoring changes Of L-glutamate concentration at glutamate-secreting cell cultures. The design of the glutamate microelectrodes is based on incorporating L-glutamate oxidase and horseradish peroxidase into a redox-hydrogel containing PVI19-dmeOs as the redox mediator and immob

Adaptive Control -- A Way to Deal with Uncertainty

This paper approaches the uncertainty problem from the point of view of adaptive control. The uncertainty is reduced by continuous monitoring of the response of the system to the control actions and appropriate modifications of the control law. It is shown that this approach makes it possible to deal with uncertainties that cannot be handled by high gain robust feedback control.

Development of Protein Microarray Chip Technology: An Outlook towards Proteomics and Diagnostics

One attractive method for monitoring biomolecular interactions in a highly parallel fashion is the use of microarrays. Microarrays can be applied for screening proteins which makes it an attractive tool in clinical diagnostics, drug discovery studies and basic protein research; even though many methodological challenges and ones relating to the quality control of microarrays still need to be solve
