Ever since Wong–Riley first reported in the late 1970s that histological staining using the chemical reactions of cytochrome oxidase (CO), a metabolic enzyme in the mitochondria, is useful to reveal the cytoarchitecture of the brain (Wong-Riley, 1979), the CO histochemistry method has been widely used in the field of neuroanatomy, especially in carnivores and primates. It has been suggested tha...

Thirty-two specimens of the Nile crocodile, Crocodylus niloticus Laurenti (Reptilia: Crocodylidae), from the Kruger National Park, South Africa, and its vicinity were examined for pentastomid parasites during 1995 to 1999 and 2010 to 2011. Pentastomid parasites occurred throughout the year and were widespread in the study area with an overall prevalence of 97% and an overall mean abundance of 2...

Familial dysautonomia is a rare syndrome of childhood affecting the nervous system. As the name suggests, dysfunction of the autonomic system is a prominent feature. It was first recognized as a separate entity by Riley, Day, Greeley and Langford (1949), the first large series being described by Riley (1952). So far, about 70 patients have been recorded. Though the fully developed syndrome is u...

Reflecting on new research by Cécile Viboud and colleagues, Steven Riley describes how understanding complex influenza dynamics can aid the design of influenza programs in China. Please see later in the article for the Editors' Summary.

In their seminal 1983 paper, M. Maxey and J. Riley introduced an equation for the motion of a sphere through fluid. Since this features Basset history integral, popularity has broadened use certain form fractional differential to study inertial particle motion. we give comprehensive theoretical analysis Maxey-Riley equation. particular, build on previous local in time existence uniqueness resul...
