Microvessel haemodynamics: interesting news which is not NO news?

Visceral obesity, a key factor of the metabolic syndrome and clinically to be recognized as an ‘apple-shape’ habitus and an increased waist circumference, is a strong predictor of cardiovascular events. There is a staggering increase in the prevalence of obesity in westernized societies in conjunction with an increase in type 2 diabetes and (sub)clinical atherosclerosis. From a clinical point o...

No News is Good News

It seems plausible that an increase in stock market volatility raises required stock returns, and thus lowers stock prices. We develop a formal model of this volatility feedback effect using a simple model of changing variance (a quadratic generalized autoregressive conditionally heteroskedastic, or QGARCH, model). Our model is asymmetric and helps to explain the negative skewness and excess ku...

NO news is good news.

NO news is good news for plants.

The organization of redox signaling and the use of nitric oxide (NO) to transmit information, modulate biological processes or create cellular damage are highly complex. Recent reports provide an exceptional picture of NO production, of the regulation of NO bioactivity through detoxification reactions and of biochemical events by which NO transduces signals into cellular responses, in particula...

News, Uncertainty and Economic Fluctuations (No News Is Good News)

We formalize the idea that uncertainty is generated by news about future developments in economic conditions which are not perfectly predictable by the agents. With a simple model of limited information we show that uncertainty shocks can be obtained as the square of news shocks. We develop a two-step econometric procedure to estimate the effects of news and we find highly nonlinear effects. La...
