A novel, rapid and cost-effective trifluoperazine dihydrochloride (TFPH) decolorization assay is described for the screening of antioxidant activity. A chromogenic reaction between TFPH and potassium persulfate at low pH produces an orange-red radical cation with maximum absorption at 502 nm in its first-order derivative spectrum. TFPH was dissolved in distilled water to give a 100 mM solution....

This paper empirically examines the effect of market competition – measured either by the Herfindahl Index or the Lerner Index – on productivity growth and R&D intensity using micro data for Japan’s manufacturing sector. We found evidence of an inverted U-shaped relationship between competition and innovation when we use the Herfindahl Index as a measure of competition in the market. In additio...

Adaptive responses greatly improve the competitive capacities of bacteria in diverse environments. Here, we investigate whether bacteria can adapt to a microenvironment with distinctive softness by examining the type-IV pili (TFP)-mediated motility of Pseudomonas aeruginosa cells on brush-like surfaces that are grafted with a layer of thermally sensitive polymer chains, where the softness of th...
