Substantial evidence exists that reactive oxygen species participate in the pathogenesis of brain damage following both sustained and transient cerebral ischemia, adversely affecting the vascular endothelium and contributing to the formation of edema. One likely triggering event for free radical damage is delocalization of protein-bound iron. The binding capacity for some iron-binding proteins is

An affective, somatic, and memory checklist of symptoms was administered to subjects who had no personal experience or knowledge of head injury. Subjects indicated their current experiences of symptoms, then imagined having sustained a mild head injury in a motor vehicle accident, and endorsed symptoms they expected to experience six months after the injury. The checklist of symptoms was also admi

To improve cement penetration into the cancellous bone of the acetabulum in hip arthroplasty, sequential cementation of each anchoring hole may be feasible. Since this procedure creates laminations in the cement, we have determined the conditions under which such laminations affect the strength of the cement. Cement bars made at 2, 3 or 4 minutes after the start of cement mixing and with either dr

Review of Rochelle Wright, The Visible Wall. Jews and Other Ethnic Ousiders in Sweden, Acta Universitatis Upsaliensis, 1998.

The purpose of this study is to examine some factors that influence the volume of North-South trade. The study concerns the period from the early- and mid 1970s to the early 1990s. It consists of an introductory chapter and five main chapters. Chapters 2 and 3 examine trade effects of policies implemented by the North, Chapters 4 and 5 examine trade effects of policies implemented by the South, an

The aim of the study was to investigate whether the properties of a pre-sintered, hot iso-static post-compacted ( HIP) ZrO2 are adequate for use in three-five-unit fixed partial dentures (FPDs) and to evaluate the clinical results. Twenty three five-unit FPDs were fabricated for 18 patients on a total of 56 abutments. They were all made on abutments cut with a shoulder preparation and cemented wit

Capsule Nest survival rates could not be explained by distance to habitat edges or other features used by predators. Aims To investigate if predation on Redshank nests was affected by habitat characteristics at a local scale. Methods We examined survival rates of Redshank nests on coastal meadows on the Baltic island of Gotland, Sweden, over two breeding seasons. We analysed nest survival rates

Popular Abstract in Swedish Svenska myndigheter behöver ibland samarbeta med utländska myndigheter, till exempel i ärenden som rör personer, föremål eller information som finns utomlands. Detta kan leda till komplexa juridiska problem som kräver pragmatiska lösningar. I avhandlingen undersöks rättsliga ramar för sådana lösningar. Undersökningen är särskilt inriktad på rättsligt bindande avtal som When Swedish administrative authorities co-operate with foreign administrative authorities, this may give rise to legally complex situations. This thesis investigates legal frameworks to solve the ensuing problems. The investigation in particular deals with binding agreements concluded by Swedish state authorities and municipalities with corresponding types of foreign public bodies. By the conclus

Under hösten 1993 har vi på uppdrag av FortF utfort rapporten "Utvärdering av halonersättningsmedlen Halotron II och FM-200". Rapporten har utarbetats vid Institutionen för Brandteknik, Lunds Universitet under ledning av doc Göran Holmstedt. Syftet med rapporten är att den skall fungera som en vägledning vid val av ersättningsmedel till Halon 1301. Vi har bl a behandlat de parametrar som är väsent

A mu-ISLM (micro Immuno Supported Liquid Membrane) extraction system coupled in a sequential injection analysis (SIA) configuration, capable of simultaneous sample cleanup and enrichment was developed. The capacity of the extraction channels - donor and acceptor, respectively - were reduced from originally 10 to 1.65 mu L. The acceptor channel surface was covered with a gold layer enabling immobil

The aim of this study was to evaluate the possibility of decreasing the myelotoxicity associated with radioimmunotherapy (RIT) by extracorporeal depletion of radioimmunoconjugates (RIC) from the circulation. The optimal combination of radionuclide and the time interval between injection of the RIC and the subsequent extracorporeal depletion procedure was assessed in immunocompetent rats, with resp

Popular Abstract in Swedish I denna avhandlig undersöks hur mekanisk sträckning påverkar den glatta muskulaturen som omger våra blodkärl. En ökad sträckning av blodkärlen sker till exempel vid högt blodtryck vilket leder till en förändrad struktur av kärlet, så kallad remodellering. Ett annat mekaniskt stimuli utgörs av blodets friktion mot de endotelceller som täcker blodkärlens kontaktyta mot blThe vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. The molecular mechanisms involved are not well defined, but c

Popular Abstract in Swedish För att pröva om värdering av kvalitet i kollektivtrafik med Stated Preferences-metoden kan göras i brevenkäter skickades olika enkäter ut till i förväg kontaktade bussresenärer. Studien visar att metoden kan användas i brev och att typen med parvisa val i så fall bör användas. En annan studie visar att erfarenheten av det man värderar har stor betydelse för värderingenTo test whether it was possible to conduct a Stated Preference study by mail, six different types of questionnaires were sent out to previously contacted bus passengers. Several quality comparisons showed that binary choices worked best. Another study showed that the experiences of travellers are of great importance to their evaluations.
