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

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

    Abstract : 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. READ MORE

  4. 17. Molecular Cloning and Functional Characterization of Factors Involved in Post-transcriptional Gene Expression

    Author : Shao-Bo Jin; Lars Wieslander; Maria Carmo-Fonseca; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene expression; pre-mRNA processing; pre-rRNA processing; Molecular biology; Molekylärbiologi;

    Abstract : Gene expression in the eukaryotic cell is a fundamental cellular process, which consists of several distinct steps but extensively coupled to each other. From site of transcription in the nucleus to the cytoplasm, both mRNA and rRNA are associated with a proper set of proteins. READ MORE

  5. 18. Molecular structure and intracellular location of five RNA : associated proteins in the salivary glands of the dipteran Chironomus tentans

    Author : Sun Xin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : hnRNPs; RNA-binding domains; shuttling proteins; non-shuttling proteins; nucleo-cytoplasmic transport; SR proteins;

    Abstract : The structure and intracellular flow of specific RNA-associated proteins have been characterized in the salivary gland cells in the dipteran Chironomus tentans. These cells contain four polytene chromosomes (I-IV), two of which harbour a nucleolus. READ MORE

  6. 19. Transcription and transport of a messenger RNP particle : novel regulatory mechanisms

    Author : Karin Kylberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In all living cells gene expression is a central process that involves several steps, including transcription, processing, transport and translation. A fine-tuning of these events is a pre-requisite for proper cellular function. READ MORE

  7. 20. The decay of beauty quark to τ lepton and neutrino in the DELPHI experiment at LEP

    Author : Gian Claudio Zucchelli; J.D. Hansen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Abstract : Using 3.5 millions hadronic Z0 events collected during the LEP1 period at the DELPHI detector, the decays of b quarks to tvt have been searched for in both the inclusive and exclusive decay modes. The analysis technique is based on b-tagging, missing energy and identifications of t products. READ MORE
