  1. 1. DNA repair and the p53 pathway in ischemic and traumatic brain injury

    Författare :Gregor Tomasevic; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuronal death; DNA repair; knock-out mice; XPA; p53; mRNA; hippocampus; preconditioning; hypothermia; trauma; Brain; ischemia; neurobehavior; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Ischemic and traumatic brain damage are major causes of disability and death. While much effort has been spent to develop pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. LÄS MER

  3. 2. Diversity and interactions of begomoviruses and their associated DNA-satellites

    Författare :Muhammad Naeem Sattar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : To study the diversity of begomovirus/DNA-satellite complexes, plants of one crop species (okra; Abelmoschus esculentus) and one weed species (Ageratum conyzoides), both with leaf curling symptoms, were analyzed. Sequence analyses of complete genome components revealed a unique begomovirus/DNA-satellite complex in both plants. LÄS MER

  4. 3. Systematics, phylogeography and polyploid evolution in the Dactylorhiza maculata complex (Orchidaceae)

    Författare :David Ståhlberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ITS; morphometry; taxonomy; Systematic botany; Växtekologi; Plant ecology; vegetation analysis; recombination; polyploidy; plastid DNA; niche differentiation; chemotaxonomy. Physiology of nonvascular plants; morphology; phytogeography; hybrid zone; glacial refugia; Dactylorhiza; flow cytometry; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Sammanfattning : The aim of this thesis was to investigate and describe different aspects of variation in the Dactylorhiza maculata complex and to relate the variation patterns to underlying biological processes such as Quaternary migration history, hybridization and polyploid evolution. The variation patterns were analysed at various geographic levels using molecular markers (plastid DNA and ITS of nrDNA), cytological data, morphometry and ecological data. LÄS MER

  5. 4. Epidemiological and Bacteriological Aspects of Spotted Fever Rickettsioses in Humans, Vectors and Mammals in Sweden

    Författare :Karin Elfving; Kenneth Nilsson; Eva Hjelm; Björn Olsen; Tomas Bergström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rickettsia helvetica; ticks; cultivation; serology; polymerase chain reaction PCR ; DNA sequencing; western blot; electron microscopy; meningitis; seroprevalence;

    Sammanfattning : Rickettsiae are obligate intracellular gram-negative bacteria transmitted by arthropod vectors. Rickettsiae sometimes cause disease in humans, typically with high fever, headache and occasionally an eschar.In Sweden, Rickettsia helvetica, belonging to the spotted fever group, is the only tick-transmitted rickettsia found free in nature.

  7. 5. Diversity of beans grown in Kyrgyzstan and marker-aided breeding for resistance to Bean common mosaic virus and anthracnose

    Författare :Sergay Hegay; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Common bean (Phaseolus vulgaris L.) is an important export crop in Kyrgyzstan since the end of the 20th century. Kyrgyzstan produces about 70,000 t of common beans per year, which provides jobs to 76% of the population in the Talas region. LÄS MER
