Szczepienie przeciw COVID-19 przy podejrzeniu anafilaksji po pierwszej dawce szczepionki
2022
Wraz z rosnącą liczbą wykonanych szczepień przeciwko COVID-19 (p/COVID-19) wzrasta także liczba zgłaszanych reakcji o różnym obrazie klinicznym po podaniu szczepionki. Mimo że reakcje te występują stosunkowo rzadko i nie zawsze mają charakter alergiczny, to budzą lęk. Szczególnie pacjenci, którzy doznali działań niepożądanych szczepienia, często nie są kwalifikowani do podania kolejnych dawek tym samym preparatem. Rozpoznanie ciężkiej reakcji anafilaktycznej po podaniu szczepionki mRNA i/lub uczulenie na jej składniki są przeciwwskazaniami do szczepienia preparatem mRNA p/COVID-19.
 Prezentowany przypadek pacjentki przedstawia problem prawidłowej kwalifikacji reakcji, które miały miejs…
An extended catalogue of ncRNAs in Streptomyces coelicolor reporting abundant tmRNA, RNase-P RNA and RNA fragments derived from pre-ribosomal RNA lea…
2022
Streptomyces coelicolor is a model organism for studying streptomycetes. This genus possesses relevant medical and economical roles, because it produces many biologically active metabolites of pharmaceutical interest, including the majority of commercialized antibiotics. In this bioinformatic study, the transcriptome of S. coelicolor has been analyzed to identify novel RNA species and quantify the expression of both annotated and novel transcripts in solid and liquid growth medium cultures at different times. The major characteristics disclosed in this study are: (i) the diffuse antisense transcription; (ii) the great abundance of transfer-messenger RNAs (tmRNA); (iii) the abundance of rnpB…
Transfection of lipoma cells with papilloma bovine virus subgenomic fragment.
1991
Abstract Lipoma cells with consistent chromosomal aberration have been transfected with plasmids carrying papilloma bovine virus subgenomic fragment (PBV 69). The succesful transformation of the cells was ascerted on the changed growth pattern of the cells in liquid medium, colony formation in soft agar and modified cell appearrance in electron microscopy; transfection with PBV 69 has not been, however, sufficient to immortalize lipoma cells.
Functional properties of a monoclonal antibody inhibiting the hepatitis C virus RNA-dependent RNA polymerase.
2001
The hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp), represented by nonstructural protein 5B (NS5B), has recently emerged as a promising target for antiviral intervention. Here, we describe the isolation, functional characterization, and molecular cloning of a monoclonal antibody (mAb) inhibiting the HCV RdRp. This mAb, designated 5B-12B7, binds with high affinity to a conformational epitope in the palm subdomain of the HCV RdRp and recognizes native NS5B expressed in the context of the entire HCV polyprotein or subgenomic replicons. Complete inhibition of RdRp activity in vitro was observed at equimolar concentrations of NS5B and mAb 5B-12B7, whereas RdRp activities of classica…
