Flavanone 3-hydroxylase expression in Citrus paradisi and Petunia hybrida seedlings.

Petunia hybrida and Citrus paradisi have significantly different flavonoid accumulation patterns. Petunia sp. tend to accumulate flavonol glycosides and anthocyanins while Citrus paradisi is known for its accumulation of flavanone diglycosides.

Does lack of diapause result in less insect seasonality?

Unlike their temperate zone and tropical African relatives, flesh flies from the Neotropics lack the capacity for diapause. Yet, our trapping data reveal marked seasonality in flies from Panama, demonstrating that diapause is not essential for generating their seasonal patterns of abundance.

The quality of radiographs used in the pretreatment review of dental claims.

The purpose of the study was to assess the quality of radiographs accompanying claims submitted for pretreatment review, and to determine the relative importance of radiograph quality in dental consultants' decisions regarding the necessity and appropriateness of crown services. Findings indicate that: 1) the technical quality of radiographs in the sample is adequate for most criteria; and 2) radiograph quality, number, and type of film submitted do not explain much of the variation in disagreements between the direct and indirect assessments of crown services. The most important radiograph variables influencing pretreatment review decisions appear to be the number of periapical films submitted for review, and the density/contrast of the radiographs.
