  1. 16. Displaced abomasum and ketosis in dairy cows : blood profiles and risk factors

    Författare :Lena Stengärde; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : High producing dairy cows struggle to meet energy demands and handle various transitional changes in late gestation and early lactation. Negative energy balance in early lactation is inevitable and metabolic disorders may follow as a consequence of a deep negative energy balance. LÄS MER

  3. 17. Molecular dissection of B-lymphocyte signalling using expression profiling

    Författare :Jessica M Lindvall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Btk; B-lymphocyte; gene expression profiling; signal transduction;

    Sammanfattning : Gene expression profiling and bioinformatics have emerged into playing a large and diverse role in many aspects of both the clinical and molecular research. These two approaches have in this thesis work been used in combination in order to shed light to the role of Bruton's tyrosine kinase (Btk) in B-lymphocyte development and signal transduction.

  4. 18. Dynamics of some vibro-impacting systems with amplitude constraints

    Författare :Jan-Olov Aidanpää; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis concerns the dynamics of some vibro-impacting systems with fixed or moving amplitude constraints. It is based on and includes five papers, marked A to E. Simple models of three different vibro-impacting systems with applications in the fields of impact hammers, granular flow and disk brakes in vehicles are analysed. LÄS MER

  5. 19. The novel sources of the neurotoxin BMAA in aquatic environments

    Författare :Sandra Lage; Sara Jonasson Rydberg; Ulla Rasmussen; Ann-Sofi Rehnstam-Holm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-N-methylamino-L-alanine; diatoms; dinoflagellates; shellfish; cockles; PST; växtfysiologi; Plant Physiology;

    Sammanfattning : Neurotoxinet β -N-metylamino -L-alanin (BMAA) anses vara en potentiell miljöriskfaktor för utvecklingen av den neurodegenerativa sjukdomen amyotrofisk lateralskleros (ALS) och har en potentiell roll i flertalet andra neurodegenerativa sjukdomar. Sedan 2003, då det upptäcktes att BMAA produceras av den symbiotiska cyanobakterien Nostoc punctiforme  har flera andra BMAA producerande cyanobakteriearter identifierats. LÄS MER

  7. 20. Fluorescence in situ hybridization for the detection of genetic alterations in prostate and bladder malignancies : significance as a genetic marker to predict the patient prognosis

    Författare :Hideyasu Matsuyama; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : Prostate cancer and bladder cancer are common urological malignancies in man, while a lack of basic information underlying the oncogenesis and the tumor progression makes it difficult to form therapeutic strategies against these malignancies. Recent advances of molecular biology revealed that genetic alteration play a crucial role in the oncogenesis and progression of these tumors. LÄS MER
