  1. 1. Application of Artificial Gel Antibodies for the Detection and Quantification of Proteins in Biological Fluids

    Author : Nasim Ghasemzadeh; Fred Nyberg; Dom M. Desiderio; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : The molecular-imprinting method has previously been used for the synthesis of artificial gel antibodies, highly selective for various proteins. In present study, we have synthesized artificial gel antibodies against haemoglobin, albumin and different forms of growth hormone with the aim to develop a simple and rapid procedure to measure the concentration of these protein biomarkers in samples of clinical interest.

  2. 2. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity

    Author : Alina Mostovaya; Lars Tranvik; Colin Stedmon; Uppsala universitet; []
    Keywords : dissolved organic matter; DOM; dissolved organic carbon; DOC; PARAFAC; reactivity continuum model; ultrahigh resolution mass spectrometry; FT-ICR-MS; organic matter characterization; decomposition kinetics; baseline metabolism; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. READ MORE

  3. 3. Molecular-level dissolved organic matter dynamics in lakes : Constraints on reactivity and persistence

    Author : Anne Marie Kellerman; Lars J. Tranvik; Dolly N. Kothawala; Thorsten Dittmar; Robert G. M. Spencer; Uppsala universitet; []
    Keywords : dissolved organic matter; DOM; dissolved organic carbon; organic matter characterization; fluorescence; PARAFAC; molecular weight; mass spectrometry; FT-ICR-MS; boreal lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Dissolved organic matter (DOM) is a central component of the global carbon cycle. Thus, small changes to the amount of DOM imported, processed and produced within lakes can have a large effect on regional carbon budgets. In addition to being a vital energy source at the base of the aquatic food web, DOM is physico-chemically reactive. READ MORE

  4. 4. Characterisation of natural dissolved organic matter with liquid chromatography and high resolution mass spectrometry

    Author : Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Per J.R. Sjöberg; Jeffrey A. Hawkes; Norbert Hertkorn; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aquatic carbon cycle; dissolved organic matter; DOM; high resolution mass spectrometry; online liquid chromatography; organic matter characterization; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Dissolved organic matter (DOM) is one of the most heterogeneous and complex mixture on Earth. DOM plays a crucial role in biogeochemical processes on the global scale and it is essential to sustain and regulate the biological processes in aquatic ecosystems. READ MORE

  5. 5. Effects of Sunlight on Organic Matter and Bacteria in Lakes

    Author : Måns Lindell; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; stimulation; carbon; humic; freshwater; pelagial; DOM; DIC; DOC; degradation; transformation; UV-B; photooxidation; UV-A; inhibition; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : This thesis examines the role of sunlight, specifically ultraviolet-B radiation (280-320 nm), on dissolved organic matter (DOM) and bacteria in lakes. Field experiments in lakes with different humic contents and geographical locations have been performed. Photooxidation result in that part of DOM is oxidized to inorganic carbon (DIC), mainly CO2.
