Bacillus cereus efflux protein BC3310 - a multidrug transporter of the unknown major facilitator family, UMF-2

open access: yesFrontiers in Microbiology, 2015
Phylogenetic classification divides the major facilitator superfamily (MFS) into 82 families, including 25 families that are comprised of transporters with no characterized functions.

The effect of ethidium bromide on DNA internal motions

open access: yesBiophysical Journal, 1980
In the present study using /sup 31/P and /sup 1/H NMR, we have measured DNA area and relaxation time changes which occur when the intercalating drug ethidium bromide (EB) binds to a 300-base-pair-long DNA fragment. We find that when EB binds to DNA, /sup 1/H, and /sup 31/P NMR resonance area becomes unmeasurable within a two-base-pair-long region.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Astrocytic connexin43 phosphorylation contributes to seizure susceptibility after mild traumatic brain injury

open access: yesThe FEBS Journal, EarlyView.
Astrocytic gap junctions formed by connexin43 (Cx43) help maintain brain homeostasis. After mild traumatic brain injury (TBI), total cortical Cx43 increases and redistributes toward a soluble, non‐junctional pool with elevated hemichannel activity and increased phosphorylation at serine 368 (pCx43S368).

Fourier transform infrared spectroscopic study of intercalation of ethidium bromide in calf thymus DNA and poly(da dt), 1992 [PDF]

open access: yes
An 8 mole (base pair)/liter aqueous solution of DNA, and a 4 mmole (base pair) aqueous solution of Poly(dA dT) were prepared for the study of the physical mechanism of complexation with an ethidium bromide solution.

Identification of natural compound inhibitors for multidrug efflux pumps of Escherichia coli and Pseudomonas aeruginosa using in silico high-throughput virtual screening and in vitro validation.

open access: yesPLoS ONE, 2014
Pseudomonas aeruginosa and Escherichia coli are resistant to wide range of antibiotics rendering the treatment of infections very difficult. A main mechanism attributed to the resistance is the function of efflux pumps.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

open access: yesInsect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Propentofylline reduces glial scar development following gliotoxic damage in the rat brainstem

open access: yesArquivos de Neuro-Psiquiatria
Propentofylline is a xanthine derivative that depresses activation of glial cells, whose responses contribute to neural tissue damage during inflammation.
