Abstract The SARS-CoV-2 Omicron BA.1 variant emerged in 2021 1 and has multiple mutations its spike protein 2 . Here we show that the of a higher affinity for ACE2 compared with Delta, marked change antigenicity increases Omicron’s evasion therapeutic monoclonal vaccine-elicited polyclonal neutralizing antibodies after two doses. mRNA vaccination as third vaccine dose rescues broadens neutralization. Importantly, antiviral drugs remdesivir molnupiravir retain efficacy against BA.1....
Abstract Although two-dose mRNA vaccination provides excellent protection against SARS-CoV-2, there is little information about vaccine efficacy variants of concern (VOC) in individuals above eighty years age 1 . Here we analysed immune responses following with the BNT162b2 2 elderly participants and younger healthcare workers. Serum neutralization levels binding IgG or IgA after first dose were lower older individuals, a marked drop over old. Sera from showed potency B.1.1.7 (Alpha),...
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike N-terminal domain (NTD) remains poorly characterized despite enrichment of mutations in this region across variants concern (VOCs). Here, we examine the contribution NTD to infection and cell-cell fusion by constructing chimeric spikes bearing B.1.617 lineage (Delta Kappa variants) NTDs generating pseudotyped lentivirus. We find that Delta on a or wild-type (WT) background increases S1/S2 cleavage efficiency virus entry,...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of disease 2019 (COVID-19), has caused widespread morbidity and mortality since its onset in late 2019. Here, we demonstrate that prior infection with human cytomegalovirus (HCMV) substantially increases SARS-CoV-2 vitro. HCMV is a common herpesvirus carried by 40%-100% population, which can reactivate lung under inflammatory conditions, such as those resulting from infection. We show both endothelial...
Increasing functionality, growing media volumes and dynamic data in today's in-vehicle information systems bear new challenges for user interaction design. Traditional hierarchical menu-based can only provide limited support while search-based approaches are promising. In this work we assess different search techniques interfaces. particular compare free across all items with categorized search. Our experiments functional prototypes show that is more efficient easier to use than searching...
As part of a Danish context educational reforms since 2013, digital learning platforms (DLPs) are mandatory in primary and lower secondary education. Teacher-created courses available DLPs can be shared, remixed, reused by other teachers, providing wide range for systematic studies. In this article, we present an analysis the Science Math courses’ popularity. Based on previous research didactical theory, focus question: Can variables discriminate most least popular platform Meebook? If so,...
In Denmark, oral examination is widely used. During the first period of Covid-19 shutdown had to be carried out through video conference systems. Denmark as well internationally there little research on topic. How do students experience while sitting at home? does technology affect practice? and teachers deal with nervousness? exam dialogue experienced under digital conditions? this study we investigate students-and experiences online a university college in Denmark. The based statistical...
In this article, we present the first systematic study of how teachers design courses in newly implemented digital learning platforms Denmark. The is based on collection and double coding 102 most downloaded course designs platform Meebook. descriptive data analysed light Meebook’s affordances, previous research didactical theory. Our analysis focusses three main intentions introduction for K9-schools. This concerns firstly use objectives their assessment, secondly relation to intention...
Denne begrebsartikel søger at bestemme fænomenet undervisning, identificere didaktiske opgaver og udvikle en taksonomi for dannende undervisning. For bidrage med ny tilgang introduceres til Sünkels fænomenologisk funderede undervisningsbegreb. Dette synes dog overse indholdsbegrebets dobbelthed, som der plæderes ved hjælp af Pranges pædagogiske pegehandling. Det er imidlertid ikke kun læreren, peger, men også den lærende. Gennem model didaktikkens indre struktur identificeres de centrale...
