  1. 6. Biomarker Discovery in Cutaneous Malignant Melanoma : A Study Based on Tissue Microarrays and Immunohistochemistry

    Författare :Margrét Agnarsdóttir; Fredrik Ponten; Peter Naredi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibody-based proteomics; automated analysis; biomarker; immunohistochemistry; malignant melanoma; survival; tissue microarray; Tumour biology; Tumörbiologi; Pathology; Patologi; Molecular medicine; Molekylär medicin; Medical Science; Medicinsk vetenskap; Pathology; Patologi;

    Sammanfattning : The incidence of cutaneous malignant melanoma has increased dramatically in Caucasians the last few decades, an increase that is partly explained by altered sun exposure habits. For the individual patient, with a localized disease, the tumor thickness of the excised lesion is the most important prognostic factor. LÄS MER

  2. 7. Gill EROD Activity in Fish : A Biomarker for Waterborne Ah-receptor Agonists

    Författare :Alexandra Abrahamson; Ingvar Brandt; Björn Brunström; Janneche Utne Skaare; Uppsala universitet; []
    Nyckelord :Biology; biomarker; fish; gill; CYP1A; EROD; environmental monitoring; induction; inhibition; PAH; PCB; produced water; Biologi;

    Sammanfattning : Induction of the cytochrome P450(CYP)1A protein and the connected increase in 7-ethoxyresorufin O-deethylase (EROD) activity are common biomarkers in fish. Enhanced activity of this protein signals exposure to Ah-receptor agonists such as chlorinated dioxins, co-planar polychlorinated biphenyls (PCBs) and certain polycyclic aromatic hydrocarbons (PAHs).

  3. 8. Heart failure : biomarker effect and influence on quality of life

    Författare :Patric Karlström; Urban Alehagen; Mikael Dellborg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; Biomarker; B-type natriuretic peptide; Heart failure treatment; B-type Natriuretic Peptide guided heart failure treatment; Responders; Health-related quality of life; Heart failure duration; Outcomes;

    Sammanfattning : Background and aims: Heart failure (HF) is a life threatening condition and optimal handling is necessary to reduce risk of therapy failure. The aims of this thesis were: (Paper I) to examine whether BNP (B-type natriuretic peptide)-guided HF treatment improves morbidity and mortality when compared with HF therapy implemented by a treating physician at sites experienced in managing patients with HF according to guidelines; (Paper II) to investigate how to define a responder regarding optimal cut-off level of BNP to predict death, need for hospitalisation, and worsening HF and to determine the optimal time to apply the chosen cut-off value; (Paper III) to evaluate how Health-Related Quality of Life (HR-QoL) is influenced by natriuretic peptide guiding and to study how HR-QoL is affected in responders compared to non-responders; (Paper IV) to evaluate the impact of patient age on clinical outcomes, and to evaluate the impact of duration of the HF disease on outcomes and the impact of age and HF duration on BNP concentration.

  4. 9. Advances for Biomarker Discovery in Neuroproteomics using Mass Spectrometry : From Method Development to Clinical Application

    Författare :Marcus O.D. Sjödin; Magnus Wetterhall; Jonas Bergquist; Dominic M. Desiderio; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Biomarker; Proteomics; Central Nervous System; Cerebrospinal Fluid; Traumatic Brain Injury; Cloud-Point Extraction; Neuroproteomics; Relative Quantification; Spinal Cord Stimulation; Neuropathic Pain; Analytical Chemistry; Analytisk kemi;

    Sammanfattning : Proteins offer a prominent group of compounds which may be ubiquitously affected in disease and used as biomarkers for early diagnosis, assessing treatment or drug development. Clinical proteomics aim to screen for protein biomarkers by a comprehensive analysis of all proteins expressed in a biological matrix during a certain pathology. LÄS MER

  5. 10. Molecular Portraits of Cancer : Discovery of Biomarker Signatures using Affinity Proteomics

    Författare :Petter Skoog; Institutionen för immunteknologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Breast Cancer; Pancreatic cancer; antibody microarray; Immunosignature; Global Proteome Survey; Affinity proteomics; Biomarker;

    Sammanfattning : The use of antibodies as capture molecules in assays is a common practice. By either printing monoclonal single chain fragment variables (scFvs) on a solid support – recombinant antibody microarray – or attaching them to magnetic beads – Global Proteome Survey (GPS) – we can specifically capture and measure target proteins of interest.
