  2. 1. Extraction and Chromatography of targeted emission markers in atmospheric aerosols

    Author : Hafiz Abdul Azeem; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; emission markers; mass spectrometry; supercritical CO2; trace analysis;

    Abstract : Atmospheric aerosols are a highly complex and dynamic mixture of solid particles, liquid deplots and gases. They travel across the continents and affect global climate and human health in various ways, often negatively. One important aspect of research in atmospheric aerosols is the investigation of emissions to the atmosphere from various sources. READ MORE

  4. 2. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Author : Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Abstract : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. READ MORE

  5. 3. Cerebral ischemia studied with positron emission tomography and microdialysis

    Author : Peter Frykholm; Peter Kirkpatrick; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Cerebral ischemia; penumbra; positron emission tomography; microdialysis; middle cerebral artery occlusion; Neurovetenskap; Neurology; Neurologi; Neurosurgery; neurokirurgi;

    Abstract : Stroke is the third leading cause of morbidity and mortality in the industrialized world. Subarachnoid hemorrhage (SAH), the least common form of stroke, is one of the most demanding diseases treated in neurointensive care units. Cerebral ischemia may develop rapidly, and has a major influence on outcome. READ MORE

  6. 4. Markers of inflammation and neurodegeneration in muliple sclerosis

    Author : Virginija Danylaitė Karrenbauer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The main line of my thesis projects is searching for biomarkers and evidence of optimal correlation with clinical and para-clinical outcome measurements in multiple sclerosis (MS): investigating the biochemical biomarker in blood/plasma (cerebrosterol) and in cerebrospinal fluid (CSF) (oligoclonal bands (OCB)) and the correlation with MRI lesion load (paper 1 and paper IV); investigating the genetic biomarker (CYP46A1) for susceptibility and disability progression in MS (Paper III); comparison of the well-known positron emission tomography (PET) ligand and peripheral benzodiazepine receptor (PBR) antagonist, [11C]PK11195, and a new PET ligand [11C]vinpocetine (tissue receptor biomarker). Both ligands denote areas of active ongoing inflammation in MS (paper II). READ MORE

  7. 5. Validation of Several Nucleoside Tracers as Proliferation Markers

    Author : Li Lu; Sven Reske; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; PET; cell proliferation; DNA synthesis; hydroxyurea; cimetidine; diuretic; Biofarmaci; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Positron emission tomography (PET) is a powerful method for in vivo characterization of tumor biochemistry and clinically has been used for diagnosing and grading of malignancy. A key element in oncology is proliferation potential, a feature that is assumed to be an important indicator of tumor growth. READ MORE
