  1. 1. Bovine milk microbiota - methods matter

    Författare :Josef Dahlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The idea of a bacterial community, a microbiota, in milk with the purpose of inoculating the offspring's intestine for a better start in life is very appealing from an evolutionary perspective. The overall purpose of this thesis was to investigate if such bacterial community exists in bovine milk from healthy individuals and to describe factors that affect the microbiota. LÄS MER

  3. 2. Vascular endothelial growth factor in renal cell carcinoma

    Författare :Jan Jacobsen; Börje Ljungberg; Kjell Grankvist; Torgny Rasmuson; Anders Bergh; Peter Ekman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEGF; isoforms; quantitative RT-PCR; immunohistochemistry; tissue microarray; Western blot; stage; survival; renal cell carcinoma; Urology and andrology; Urologi och andrologi;

    Sammanfattning : Background. Angiogenesis is essential for tumour growth. Vascular endothelial growth factor (VEGF) and its isoforms were investigated in relation to the clinical course in a large number of patients with renal cell carcinoma (RCC). Methods. LÄS MER

  4. 3. Aspects of Tuberculosis and HIV Coinfection in Patients at Ethiopian Health Centers

    Författare :Sten Skogmar; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV; TB; clinical scoring; TB screening; CD4 cell count; immunosuppression; immune activation;

    Sammanfattning : HIV and tuberculosis (TB) remain the two most common infectious causes of death worldwide. During the recent decade antiretroviral treatment (ART) has become available for millions of people living with HIV (PLHIV) globally; yet more than half of PLHIV have not yet initiated ART. LÄS MER

  5. 4. From single-cell transcriptomics to single-molecule counting

    Författare :Saiful Islam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : RNA-sequencing (RNA-seq) technology has been progressing so fast in the last few years and made it possible to perform transcriptome analysis at single-cell level that was even unimaginable a few years before. Nowadays, the importance of gene expression analysis at the single-cell level is increasingly appreciated for the study of complex heterogeneous tissue. LÄS MER

  7. 5. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

    Författare :Gustav Grafström; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low energy; Radiobiology; dosimetry; cell model; Radiofarmaceutisk teknik; Radiopharmaceutical technology; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; animal model;

    Sammanfattning : Background: During the last 20 years both in vitro and in vivo models have been developed for studies of the cell killing characteristics of low energy electrons, e.g. Auger electrons. This thesis deals with radiobiological effects of radiation from indium isotopes in V79 cells in vitro (Paper I-III) and the rat testis in vivo (Paper IVV). LÄS MER
