  1. 1. Carbon monoxide in biological systems An experimental and clinical study

    University dissertation from Umeå : Kirurgisk och perioperativ vetenskap

    Author : Anna-Maja Åberg; Umeå universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbon monoxide; physiological effects; systemic inflammation; analytical method; blood; exhaled air; pharmacokinetics; cigarette smoking; blood donation; cytokines; MEDICINE Surgery Anaesthetics and intensive care Anaesthetics; MEDICIN Kirurgi Anestesiologi och intensivvård Anestesiologi;

    Abstract : Background: Carbon monoxide (CO) is a toxic gas, but it is also produced endogenously when haem is degraded. When produced in vivo, CO is believed to have positive biological effects. For example it activates the production of cyclic guanosine mono-phosphate and causes vasodilatation. READ MORE

  2. 2. Photoinitiated Radical Carbonylation Using [11C]Carbon Monoxide 11C-Labelling of Aliphatic Carboxylic Acids, Esters, and Amides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oleksiy Itsenko; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; 11C-labelling; radicals; carbonylation; carbon monoxide; solvent effects; sensitizers; sulfoxides; WAY-100635; PET; Organisk kemi; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : One-step photoinitiated free radical carbonylation was employed for the rapid (5–7 min) labelling of aliphatic carboxylic acids, esters, and amides with a short-lived positron emitter 11C (t½ = 20.3 min) at the carbonyl position. The labelled compounds were synthesized from alkyl iodides (0.05–0. READ MORE

  3. 3. Carbon monoxide and nitric oxide as antimicrobial agents : focus on ESBL-producing uropathogenic E.coli

    University dissertation from Örebro : Örebro university

    Author : Charlotte Sahlberg Bang; Örebro universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; carbon monoxide; CORM-2; DETA NO; extendedspectrum beta-lactamases; nitric oxide; urinary tract infection; uropathogenic Escherichia coli; Biomedicin; Biomedicine;

    Abstract : Urinary tract infections (UTI) are common in humans and most often caused by uropathogenic Escherichia coli (E. coli). Extended-spectrum beta-lactamase (ESBL)-producing E. coli are increasing worldwide and they are frequently multidrug-resistant with limited treatment options. READ MORE

  4. 4. [11C]Carbon Monoxide in Rhodium-/Palladium-Mediated Carbonylation Reactions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Julien Barletta; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; carbonylation reaction; carbon monoxide; PET; 11C-labelling; rhodium; palladium; Organisk kemi; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : Methods for the 11C-labeling of carbonyl compounds applicable in the preparation of radiotracers for Positron Emission Tomography (PET) are described. To this end [11C]carbon monoxide at low concentration was used in transition metal- mediated reactions. READ MORE
