Type-specific human papillomavirus DNA detected in atypical glandular cell Pap tests.

Objectives: To evaluate the presence of type-specific human papillomavirus (HPV) DNA in atypical glandular cells (AGCs) from cervical liquid-based cytology and to report the relationship between HPV types and cervical histological abnormalities.

Study Design: We used a nested multiplex polymerase chain reaction assay to test AGC Papanicolaou (Pap) tests for the presence of 14 high-risk (HR) HPV types.

Results: HR HPV types were detected in 33 of 161 AGC Pap tests (20.

Firefly synchrony: a behavioral strategy to minimize visual clutter.

Most firefly species (Coleoptera: Lampyridae) use bioluminescent flashes for signaling. In some species, the flashing between males occurs rhythmically and repeatedly (synchronically) with millisecond precision. We studied synchrony's behavioral role in the North American firefly, Photinus carolinus.

Environmental influences on isoflavones and saponins in soybeans and their role in colon cancer.

Soybeans have long been recognized as an excellent source of high-quality protein. The soybean also contains a wide variety of chemical compounds that have potent bioactivity. Among these compounds are the isoflavones and the saponins.

Flash Precision at the Start of Synchrony in Photuris frontalis.

Synchronous flashing occurs in certain species of Southeast Asian and North American fireflies. Most Southeast Asian synchrony involves stationary congregating fireflies, but North American synchrony occurs in flying fireflies that do not congregate. Southeast Asian synchrony is usually continuous, but North American synchrony is interrupted.
