Metagenomic and Meta-Transcriptomic Analysis Reveal the Colonization and Expression Profile of Probiotic Strains in Humans and Animals

open access: yes, 2023
In humans and animals, probiotics are widely accepted as crucial for host health and growth. The investigation of the probiotic colonization and expression of probiotics in the host is beneficial for proper usage of probiotics and isolation of indigenous

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.

Genetically similar strains of Escherichia coli O157:H7 isolated from sheep, cattle and human patients [PDF]

open access: yes, 2012
Conclusions: The same pathogenic subtypes of VTEC O157:H7, including the highly virulent clade 8, appear to be present in both sheep and cattle in Sweden, suggesting strains can circulate freely between ruminant ...

Mixed infection with cagA positive and cagA negative strains of Helicobacter pylori lowers disease burden in The Gambia. [PDF]

open access: yes, 2011
BACKGROUND: The prevalence of Helicobacter pylori including strains with putatively virulent genotypes is high, whereas the H. pylori-associated disease burden is low, in Africa compared to developed countries.

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.

The Concept of α-Synuclein Strains and How Different Conformations May Explain Distinct Neurodegenerative Disorders

open access: yesFrontiers in Neurology, 2021
In the past few years, an increasing amount of studies primarily based on experimental models have investigated the existence of distinct α-synuclein strains and their different pathological effects.

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 ...

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.

Strain Hardening at Large Strains [PDF]

open access: yes, 1989
The strain hardening properties of various fcc metals have been investigated at large strains by means of torsion tests of short thin-walled cylinders. The results show that Stage IV occurs in all cases provided that a low enough test temperature is used; it is a nearly constant hardening rate of 2.10/sup /minus/4/ G in terms of resolved flow stress ...
