Sequence Variability of P2-Like Prophage Genomes Carrying the Cytolethal Distending Toxin V Operon in Escherichia coli O157 [PDF]

open access: yes, 2013
Cytolethal distending toxins (CDT) are potent cytotoxins of several Gram-negative pathogenic bacteria, including Escherichia coli, in which five types (CDT-I to CDT-V) have been identified so far.

The Effect of Heavy-Duty Vehicle Crossings on the State of Stress of Buried Pipelines

open access: yesMetals, 2022
The aim of this article is to quantify the loads exerted by heavy-duty vehicles when crossing over buried pipeline. This problem arises in connection to the question pertaining to the use of protective sleeves (casings) applied to gas pipelines in ...

Variation in relapse frequency and the transmission potential of Plasmodium vivax malaria [PDF]

open access: yes, 2016
There is substantial variation in the relapse frequency of Plasmodium vivax malaria, with fast-relapsing strains in tropical areas, and slow-relapsing strains in temperate areas with seasonal ...

Line strain representation and shear strain representation of 3D strain states

open access: yesPLOS ONE, 2021
The strain state in 3D space is usually expressed by the conventional method of combining three linear and shear strains. Due to the obvious differences between the first two strains, it is necessary to uncover their properties when describing deformation, studying yield and failure, and developing test apparatus or equipment.

Allogeneic Transplantation of Testicular Hyperplasia in rag1 Mutant Zebrafish

open access: yesBio-Protocol, 2016
Allogeneic organ transplantation is a powerful tool for clinical and basic research studies. However, the graft is often rejected by the host organism. Here, we describe a protocol that uses immunodeficient rag1 mutant zebrafish.

Evolution of Shh endoderm enhancers during morphological transition from ventral lungs to dorsal gas bladder

open access: yesNature Communications, 2017
Endoderm enhancer MACS1 of Sonic Hedgehog is conserved in animals with lungs. Here, the authors show that mouse without MACS1 has defective laryngeal development, and use phylogenetic analyses to show association of evolutionary lung-gas bladder ...

Diagnostics of cattle leucosis by using an biosensor based on surface plasmon resonance phenomenon

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2019
The virus of cattle enzootic leucosis leads to high losses in rural economy, implies forced slaughter of sick animals, loss of the breed, decrease in productivity, violation of reproduction processes in industrial breeding and livestock sector.

Multiple cis-Acting rDNAs Contribute to Nucleoid Separation and Recruit the Bacterial Condensin Smc-ScpAB

open access: yesCell Reports, 2017
Summary: Condensins load onto DNA to organize chromosomes. Smc-ScpAB clearly loads onto the parS sites bound by Spo0J, but other loading site(s) must operate independently of parS.

Scalable Microbial Strain Inference in Metagenomic Data Using StrainFacts

open access: yesFrontiers in Bioinformatics, 2022
While genome databases are nearing a complete catalog of species commonly inhabiting the human gut, their representation of intraspecific diversity is lacking for all but the most abundant and frequently studied taxa.
