A continuous kinetic assay for RNA-cleaving deoxyribozymes, exploiting ethidium bromide as an extrinsic fluorescent probe [PDF]
, 2002 We describe a rapid and inexpensive method to monitor the kinetics of small RNA-cleaving deoxyribozymes, based on the exogenous fluorophore ethidium bromide.

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots
Environmental Toxicology, EarlyView.ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

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

Zoo Biology, EarlyView.ABSTRACT The success of nuclear reprogramming techniques, including the G0/G1 synchronization of somatic cells, depends on species‐specific optimization. While roscovitine and serum starvation have been successfully applied in domestic and wild terrestrial mammals, their use in aquatic mammals remains poorly investigated.

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
