A trans-complementation system for SARS-CoV-2 recapitulates authentic viral replication without virulence

open access: yesbioRxiv, 2021
The biosafety level-3 (BSL-3) requirement to culture severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a bottleneck for research and countermeasure development.

Quantum network routing and local complementation [PDF]

open access: yesnpj Quantum Information, 2018
Quantum communication between distant parties is based on suitable instances of shared entanglement. For efficiency reasons, in an anticipated quantum network beyond point-to-point communication, it is preferable that many parties can communicate ...

In vivo Emergence of Colistin Resistance in Carbapenem-Resistant Klebsiella pneumoniae Mediated by Premature Termination of the mgrB Gene Regulator

open access: yesFrontiers in Microbiology, 2021
Multidrug-resistant (MDR) Klebsiella pneumoniae is a severe threat to public health worldwide. Worryingly, colistin resistance, one of the last-line antibiotics for the treatment of MDR K. pneumoniae infection, has been increasingly reported.

Shifters as sentence operators [PDF]

open access: yesJužnoslovenski Filolog, 2017
The author presents the thesis that complementary clauses and relative clauses are de facto noun phrases founded on the shifter-tandems of the type that, which..., that, who... Mutatis mutandis, constructions constituted with causal conjunctions

A split fluorescent reporter with rapid and reversible complementation

open access: yesNature Communications, 2019
Interactions between proteins play an essential role in metabolic and signaling pathways, cellular processes and organismal systems. We report the development of splitFAST, a fluorescence complementation system for the visualization of transient protein ...

Complementation [PDF]

open access: yesWormBook, 2005
Mutations in many genes can result in a similar phenotype. Finding a number of mutants with the same phenotype tells you little about how many genes you are dealing with, and how mutable those genes are until you can assign those mutations to genetic loci. The genetic assay for gene assignment is called the complementation test.

The Role of Cadaverine Synthesis on Pneumococcal Capsule and Protein Expression

open access: yesMedical Sciences, 2018
Invasive infections caused by Streptococcus pneumoniae, a commensal in the nasopharynx, pose significant risk to human health. Limited serotype coverage by the available polysaccharide-based conjugate vaccines coupled with increasing incidence of ...

Synchronic Variability in the Complementation Profile of REMEMBER: Finite vs Non-Finite Clauses in Indian and British English

open access: yesMiscelánea: A Journal of English and American Studies, 2019
This paper explores the prevalent simplification of morphosyntactic features occurring in Postcolonial Englishes (cf. e.g. Williams 1987) by addressing the hypothesis that finite complement clauses (CCs) should be more common in these varieties than a ...

On Some Control Structures in Hellenistic Greek: A Comparison with Classical and Modern Greek

open access: yesLinguistic Discovery, 2002
Control Structures in Ancient Greek typically involved infinitival complementation while in Modern Greek, finite complementation is the rule. Hellenistic Greek provides an interesting "way-station" between these two types of complementation, inasmuch as ...

Testing of Auxotrophic Selection Markers for Use in the Moss Physcomitrella Provides New Insights into the Mechanisms of Targeted Recombination

open access: yesFrontiers in Plant Science, 2017
The moss Physcomitrella patens is unique among plants in that homologous recombination can be used to knock out genes, just like in yeast. Furthermore, transformed plasmids can be rescued from Physcomitrella back into Escherichia coli, similar to yeast ...
