263 In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criti...

The production of neurons from neural progenitor cells, the growth of axons and dendrites and the formation and reorganization of synapses are examples of neuroplasticity. These processes are regulated by cell-autonomous and intercellular (paracrine and endocrine) programs that mediate responses of neural cells to environmental input. Mitochondria are highly mobile and move within and between s...

Sports Exerc., Vol. 42, No. 2, pp. 233–243, 2010. Previous studies have shown that cycling can directly influence neuromuscular control during subsequent running in some highly trained triathletes. A relationship between this altered neuromusc...

Of the commonly accepted tools for assessing habitual dietary intake in epidemiological studies, the one that is most often used in population surveys is the food frequency questionnaire (FFQ) (Briefel et al., 1992; Kushi, 1994). When using the FFQ, the results generally represent usual intakes over an extended period and are easier to collect and process. The FFQ is then used to study associat...

J. Econ.Entomol.89(1): 33-38 (1996) ABSTRACT The susceptibility of diamondback moth, Plutella xylostella (L.), larvae to 2 avermectins, abamectin and MK-243 (4"-epi-methylamino-4"deoxyavermectinBI hydrochloride), was assessed through toxicityevaluations of 17-19 geographicallydiverse populations. Both avennectins were very potent to 3rd-instar diamondbackmoth; LC50s for abamectin and MK-243 ran...

BACKGROUND This study explores the influence of two functional genetic polymorphisms in the regulated on activation in normal T-cell expressed and secreted(RANTES) promoter on the risk of hepatocellular carcinoma (HCC) occurrence in patients with alcoholic or Hepatitis C Virus (HCV)-related cirrhosis. METHODS RANTES C-28G and G-403A promoter dimorphisms and RANTES serum levels were assessed i...
