Earthworm symbiont Verminephrobacter eiseniae mediates natural transformation within the host egg capsules using type IV pili

open access: yesFrontiers in Microbiology, 2014
The dense microbial communities commonly associated with plants and animals should offer many opportunities for horizontal gene transfer (HGT) through described mechanisms of DNA exchange including natural transformation.

Natural Symmetries of the Yang-Mills Equations [PDF]

open access: yes, 1994
We define a natural generalized symmetry of the Yang-Mills equations as an infinitesimal transformation of the Yang-Mills field, built in a local, gauge invariant, and Poincar\'e invariant fashion from the Yang-Mills field strength and its derivatives to

The gonococcal genetic island and type IV secretion in the pathogenic Neisseria

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
Eighty percent of Neisseria gonorrhoeae strains and some Neisseria meningitidis strains encode a 57 kb gonococcal genetic island (GGI). The GGI was horizontally acquired and is inserted in the chromosome at the replication terminus. The GGI is flanked by

Aminoglycoside Resistance and Possible Mechanisms in Campylobacter Spp. Isolated From Chicken and Swine in Jiangsu, China

open access: yesFrontiers in Microbiology, 2021
Campylobacter is a major food-borne pathogen in humans, and previous studies reported a high prevalence of gentamicin-resistant Campylobacter isolates from food-producing animals in China.

Natural Transformation v1 [PDF]

open access: yes, 2018
Following this protocol, V. Natriegens cells can be transformed with linear fragments and plasmids based on natural transformation as described in Multiplex Genome Editing by Natural Transformation (MuGENT) for Synthetic Biology in Vibrio natriegens Dalia et. al, 2017. ACS Synthetic Biology.

Affine Structures on Jet and Weil Bundles [PDF]

open access: yes, 2009
Weil algebra morphism induce natural transformations between Weil bundles. In some well known cases, a natural transformation is endowed with a canonical structure of affine bundle.

Photoredox catalytic asymmetric dearomative [3 + 2] cycloaddition of isoquinolines with enones

open access: yesNature Communications
Asymmetric dearomative photocycloaddition has emerged as a transformative strategy for the enantioselective construction of complex three-dimensional molecular architectures from simple planar aromatic precursors. While significant progress has been made

Automating the transformation-based analysis of visual languages [PDF]

open access: yes, 2009
The final publication is available at Springer via http://dx.doi.org/10.1007/s00165-009-0114-yWe present a novel approach for the automatic generation of model-to-model transformations given a description of the operational semantics of the source ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Some categorical aspects of the inverse limits in ditopological context

open access: yesApplied General Topology, 2018
This paper considers some various categorical aspects of the inverse systems (projective spectrums) and inverse limits described in the category ifPDitop, whose objects are ditopological plain texture spaces and morphisms are bicontinuous point functions
