The use of naturally occurring botanicals with substantial antioxidant activity to prevent photoageing is receiving increasing attention. We have previously identified piceatannol and scirpusin B, which is a dimer of piceatannol, as strong antioxidants that are present in passion fruit (Passiflora edulis) seeds. In the present study, the effects of passion fruit seed extract, piceatannol, and s...

Internet gaming disorder is currently listed in the DSM-not in order to diagnose such a disorder but to encourage research to investigate this phenomenon. Even whether it is still questionable if Internet Gaming Disorder exists and can be judged as a form of addiction, problematic game play is already very well researched to cause problems in daily life. Approaches trying to predict problematic...

Several decades ago, as a young scientist, I often received advice from a notmuch-older Edward O. Wilson, especially during many long days of field work on small mangrove islands in Florida Bay. Some of it was direct and explicit—what to do, what not to do. But most of the advice was indirect, delivered during riveting discussions about what scientific discoveries and developments really advanc...

Note: This article, expressing the thoughts of Gail S. Fidler, was being developed jointly by Mrs. Fidler and Nedra P. Gillette at the time of Mrs. Fidler’s death, April 26, 2005. It was completed using notes recorded during an extensive interview and reminiscence session the 2nd week in February. Fidler, G. S., Gillette, N. P. (2005). A firm persuasion in our work—Passion and perseverance. Ame...

We previously found that passion fruit (Passiflora edulis) seeds contained a high amount of piceatannol (3,5,3',4'-trans-tetrahydroxystilbene), a natural analog of resveratrol (3,5,4'-trans-trihydroxystilbene). Resveratrol has been proposed as a potential anti-metabolic disorder compound, by its activation of sirtuin and AMP-activated protein kinase. Many reports show that resveratrol ameliorat...

The aim of this article is to explore the linkage of two microsimulators developed at the University College London. At present, these models deal independently with buses at either bus stops or traffic networks. First, both microsimulators are described in some detail. The generic way in which both models can be connected is then proposed. As a result of this analysis, the main issues for a co...

Healthy dissidence is part of the stuff of politics but when does health break down into ill health and how does that ill health manifest itself? In violence, street riots, anarchism, terrorism, revolution, civil war, or in forms of deviant thought and behavior that may be regarded as manifestations of mental illness? The term dissenter came into being in 1639 to describe individuals who separa...
