  1. 1. Reverse transcriptase assay for analysis of resistance to anti-HIV drugs and their mechanism of action

    Författare :Xingwu Shao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV-1; RT; antiviral drugs; NRTls; NNRTls; drug resistance; viral load;

    Sammanfattning : Reverse transcriptase (RT) is a viral enzyme and one of the main targets for drugs against human immunodeficiency virus (HIV). This work presents a set of sensitive non-radioactive RT assays were developed: standard RT inhibition assay (IC assay); RT binding inhibition assay; RTprotein detection assay and template-primer destruction assay or chain termination assay (CT assay).

  2. 2. Likelihood-Based Panel Unit Root Tests for Factor Models

    Författare :Xingwu Zhou; Johan Lyhagen; Joakim Westerlund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Panel unit root; Exact factor model; Dynamic factor model; Maximum likelihood; Principal components; Lagrange multiplier;

    Sammanfattning : The thesis consists of four papers that address likelihood-based unit root tests for panel data with cross-sectional dependence arising from common factors.In the first three papers, we derive Lagrange multiplier (LM)-type tests for common and idiosyncratic unit roots in the exact factor models based on the likelihood function of the differenced data.
