Popular Abstract in Swedish Transplantation av nervvävnad till hjärnan är inte en ny idé. Redan 1890, publiserade Thompson de första försöken att transplantera vuxen hjärnvävnad till det vuxna centrala nervsystemet och han rapporterade att vävnaden överlevde i sju veckor "without wholly losing its identity". Trots detta var det först under 1970-talet som metoderna för intracerebral nervcellstranspIntracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. We have investigated the feasibli

Manufacturing is an industry in which the effects of globalization are obvious. Manufacturing costs are a key factor in this respect and affect, for example, decisions about offshoring, i.e., moving production abroad. If Sweden and other Western countries are to maintain large manufacturing sectors, they must be competitive, making cost one of the most critical parameters. The work presented here

Using simple waves and six-vector formalism, the propagation of electromagnetic waves in nonlinear, bianisotropic, nondispersive, homogeneous media is analyzed. The Maxwell equations are formulated as an eigenvalue problem, whose solutions are equivalent to the characteristic directions of the wave front. Oblique incidence of plane waves in vacuum on a half space of nonlinear material is solved, g

Methane is a powerful greenhouse gas and growing concern regarding global climate changes over the last years has pointed out the need to quantify and control the leaking of methane into the atmosphere. Landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of geoelectrical resistiv

Poly(propylene imine) dendrimers have been shown to be promising 3-dimensional polymers for the use in the pharmaceutical and biomedical applications. Our aims of this study were first, to synthesize a novel type of dendrimer with poly(propylene imine) core and maltose-histidine shell (G4HisMal) assessing if maltose-histidine shell can improve the biocompatibility and the ability to cross the bloo

Lemierre syndrome usually affects otherwise healthy adolescents or young adults and occurs at an overall rate of 1 to 10 cases per million person-years with an estimated fatality rate of 4 to 9%. Diagnostic criteria remain debated and include acute neck/head bacterial infection (often tonsillitis caused by anaerobes at high potential for sepsis and vascular invasion, notably Fusobacterium necropho

The study of molecular dynamics involves observations of the motion of nuclei and electrons. While nuclear motion is usually on the picosecond or femtosecond timescale, attosecond precision is necessary to directly observe the motion of electrons. Ultrashort laser pulses have become established as a viable tool for probing femtosecond dynamics by irradiating the target for only extremely short tim
