A tanulmány Dosztojevszkij gyermek- és nőábrázolásának legfontosabb sajátosságait vizsgálja. szerző igyekszik rámutatni az adott korszak ambivalens jelenségeire, melyek befolyást gyakoroltak a nevelésre, továbbá író világában látensen mindig jelen levő evangéliumi ideál érvényesülésére. Dosztojevszkij-szakirodalomban viszonylag kevés figyelmet kapott kérdés, hogy milyen szerepet játszik műveibe...
Abstract RNA polymerase inhibition plays an important role in the regulation of transcription response to environmental changes and virus-host relationship. Here we present high-resolution structures two such RNAP-inhibitor complexes that provide structural bases underlying RNAP archaea. The Acidianus two-tailed virus encodes RIP factor binds inside DNA-binding channel RNAP, inhibiting by occlu...
Purpose: To evaluate the application of bacterial liposomes and archaeosomes as a novel drug delivery system for in vitro cytoplasmic delivery of molecules into cancer cells. Methods: Bacterial membrane lipids were extracted using chloroform and methanol. Bacterial liposomes and archaeosomes of E. coli, Acidianus brierleyi and Sulfolobus acidocaldarius were prepared using film method and their ...
Syftet med den här artikeln är att studera hur människor skapar mening av svenska coronastrategin samt de implementerar denna strategi i sina vardagsliv. Artikeln bygger på en intervjustudie åtta personer boendes Stockholm. Samtliga intervjuer genomfördes under pandemins initiala fas (april–maj 2020). tar sin teoretiska utgångspunkt ett risksociologiskt intresse för kring osäkerheter, exemplifi...
Little is known about how archaeal viruses perturb the transcription machinery of their hosts. Here we provide the first example of an archaeo-viral transcription factor that directly targets the host RNA polymerase (RNAP) and efficiently represses its activity. ORF145 from the temperate Acidianus two-tailed virus (ATV) forms a high-affinity complex with RNAP by binding inside the DNA-binding c...
Biological membranes create compartments, and are usually formed by lipid bilayers. However, in hyperthermophilic archaea that live optimally at temperatures above 80°C the membranes are monolayers which resemble fused bilayers. Many double-stranded DNA viruses which parasitize such hosts, including the filamentous virus AFV1 of Acidianus hospitalis, are enveloped with a lipid-containing membra...
Genes of Sulfolobus metallicus that appeared to be upregulated in relation to growth on either ferrous iron or sulfur were identified using subtractive hybridization of cDNAs. The genes upregulated during growth on ferrous iron were found in a cluster, and most were predicted to encode membrane proteins. Quantitative reverse transcription-PCR of cDNA showed upregulation of most of these genes d...
