Unraveling topoisomerase IA gate dynamics in presence of PPEF and its preclinical evaluation against multidrug-resistant pathogens

Communications Biology, 2023
Two potent inhibitors PPEF and BPVF of bacterial TopoIA enzymes function by impairing DNA binding and thus DNA cleavage and relaxation activities of bacterial topoisomerase I enzymes.

Beta-adrenergic receptor 1 selective antagonism inhibits norepinephrine-mediated TNF-alpha downregulation in experimental liver cirrhosis. [PDF]

PLoS ONE, 2012
BACKGROUND: Bacterial translocation is a frequent event in cirrhosis leading to an increased inflammatory response. Splanchnic adrenergic system hyperactivation has been related with increased bacterial translocation. We aim at evaluating the interacting

Oral bacterial DNA findings in pericardial fluid

Journal of Oral Microbiology, 2014
Background: We recently reported that large amounts of oral bacterial DNA can be found in thrombus aspirates of myocardial infarction patients. Some case reports describe bacterial findings in pericardial fluid, mostly done with conventional culturing ...

In situ electrochemical investigation of the interaction between bacteria Xylella fastidiosa DNA and copper(II) using DNA-electrochemical biosensors

Electrochemistry Communications, 2021
New emerging bacterial plant diseases are spreading fast in different geographical regions, and effective safety measures have not been found. Xylella fastidiosa (Xf) is a Gram-negative bacterial plant pathogen classified as a priority quarantine pest ...

Blood Metagenome in Health and Psoriasis

Frontiers in Medicine, 2020
A survey and analytical assessment of the results of fundamental works on studying blood metagenome (set of all non-human DNA) is carried out. All works on determining bacterial DNA concentration in the whole blood of healthy people are reviewed ...

DNA extraction: High yield is not synonymous with high diversity

Bioingeniøren, 2017
The quality, amount, and, in the case of polymicrobial samples, diversity of isolated DNA presupposes the precision of downstream application results. As part of a larger study on colorectal cancer, the aim of this work was to identify the DNA extraction

Combined bacterial and fungal targeted amplicon sequencing of respiratory samples: Does the DNA extraction method matter?

PLoS ONE, 2020
BACKGROUND:High-throughput sequencing techniques are used to analyse the diversity of the respiratory microbiota in health and disease. Although extensive data are available regarding bacterial respiratory microbiota, its fungal component remains poorly ...

Use of the checkerboard DNA-DNA hybridization technique for bacteria detection in Aedes aegypti (Diptera:Culicidae) (L.)

Parasites & Vectors, 2011
Background Bacteria associated with insects can have a substantial impact on the biology and life cycle of their host. The checkerboard DNA-DNA hybridization technique is a semi-quantitative technique that has been previously employed in odontology to ...
