Microbiology and Immunology, EarlyView.ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

Intercalation of ethidium bromide into a triple-stranded oligonucleotide
Nucleic Acids Research, 1991 We have examined the ability of a cationic planar chromophore, ethidium bromide, to intercalate into a short, defined triple helix. Using UV absorption, fluorescence spectroscopy and a gel retardation assay we demonstrate that ethidium bromide is able to bind to a triple helix with a lower affinity than to the corresponding duplex. Energy transfer from

Integrative Zoology, EarlyView.Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Entomologia 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.

The effect of ethidium bromide on DNA internal motions
Biophysical 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.
