"Es war eine unendliche Leere in mir" : eine kritische Diskursanalyse zu den Identitätskonstruktionen der mutmaßlichen Rechtsterroristin Beate Zschäp…

2017

Vuonna 2011 saksalainen yhteiskunta järkyttyi vuosia kestäneen murhasarjan tultua ilmi. Uusnatsistisen terroristiryhmä NSU:n (Nationalsozialistischer Untergrund) oletettu kolmas jäsen Beate Zschäpe antoi ensimmäisen lausuntonsa vasta vuonna 2015. Vuonna 2013 alkaneessa oikeudenkäynnissä on syksyllä 2017 siirrytty loppupuheenvuoroihin. Tämä tutkimus käsittelee Beate Zschäpen antamassa kirjallisessa 53-sivuisessa oikeudenkäyntilausunnossa esille tulevia identiteettejä sekä sitä, millaisin kielellisin keinoin niitä konstruoidaan. Koska kyse on kielestä vallankäytön välineenä, soveltuu kriittinen diskurssintutkimus tämän tutkimuksen teoreettis-metodiseksi taustaksi. Analyysi on toteutettu yhden…

Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.

2011

Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…

Characterization of the autoantigen La (SS-B) as a dsRNA unwinding enzyme

1997

During the analysis of the La (SS-B) autoantigen for catalytic activities an ATP-dependent double-stranded RNA unwinding activity was detected. Both native and recombinant La proteins from different species displayed this activity, which could be inhibited by monospecific anti-La antibodies. La protein was able to melt dsRNA substrates with either two 3'-overhangs or a single 3'- and a 5'-overhang. Double-stranded RNAs with two 5'-overhangs were not unwound, indicating that at least one 3'-overhang is required for unwinding. Sequence elements of the La protein that might be involved in dsRNA unwinding, such as an evolutionarily conserved putative ATP-binding motif and an element that is hom…

Emergence and Disappearance of an Immune Molecule, an Antimicrobial Lectin, in Basal Metazoa

2003

Sponges (phylum Porifera) represent the evolutionarily oldest metazoans that comprise already a complex immune system and are related to the crown taxa of the protostomians and the deuterostomians. Here, we demonstrate the existence of a tachylectin-related protein in the demosponge Suberites domuncula, termed Suberites lectin. The MAPK pathway was activated in response to lipopolysaccharide treatment of the three-dimensional cell aggregates, the primmorphs; this process was abolished by the monosaccharide D-GlcNAc. The cDNA encoding the S. domuncula lectin was identified and cloned; it comprises 238 amino acids (26 kDa) in the open reading frame. The deduced protein has one potential trans…
