1. 1. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

   Författare :Mark Lubberink; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

   Sammanfattning : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. LÄS MER

3. 2. Stable bromine isotopic composition of methyl bromide : Method development and applications

   Författare :Axel Horst; Örjan Gustafsson; Detlef Schulz-Bull; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The isotopic composition of ozone depleting methyl halides may provide valuable information on the sources and sinks of these compounds. However, so far mostly stable carbon isotope analysis of methyl chloride and methyl bromide (CH3Br) has been attempted. LÄS MER

4. 3. Identification of brominated organic compounds in aquatic biota and exploration of bromine isotope analysis for source apportionment

   Författare :Maria Unger; Örjan Gustafsson; Lillemor Asplund; Per Andersson; Sheryl Tittlemier; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polybrominated dibenzo-p-dioxins PBDDs ; NMR spectroscopy; preparative capillary gas chromatography PCGC ; stable bromine isotope ratio; GC-multiple collector- ICP-MS; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

   Sammanfattning : Brominated organic compounds (BOCs) of both natural and anthropogenic origin are abundant in the environment. Most compounds are either clearly natural or clearly anthropogenic but some are of either mixed or uncertain origin. LÄS MER

5. 4. On the Use of 76Br-labelled Monoclonal Antibodies for PET : Preclinical Evaluation of Halogenated Antibodies for Diagnosis and Treatment of Cancer

   Författare :Johanna Höglund; Katrine Riklund-Åhlström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; bromine-76; positron emission tomography; monoclonal antibodies; cancer; direct and indirect radiohalogenation; Onkologi; Oncology; Onkologi; radiologi; Radiology;

   Sammanfattning : Radioactive substances are used in vivo to localize and characterize malignant tumours, generally by scintigraphic methods. In this context positron emission tomography (PET) in combination with radiolabelled monoclonal antibodies (mAbs) may provide a sensitive and specific method for detection of cancer. LÄS MER

7. 5. Compound-specific bromine isotope analysis of methyl bromide using GC-multiple collector mass spectrometry

   Författare :Axel Horst; Örjan Gustafsson; David Bastviken; Ulla Sellström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The isotopic composition of ozone depleting methyl halides may provide valuable information on the sources and sinks of these compounds. However, so far mostly stable carbon isotope analysis of methyl chloride and methyl bromide has been at­tempted. LÄS MER
