Plasma beta-endorphin (beta-EP) levels were measured at different stages of metamorphosis in anuran species, namely Rana catesbeiana, R. pipiens, and Xenopus laevis. The mean levels of beta-EP in tadpoles and postmetamorphic juveniles were significantly higher than adult levels in all three species examined. The pattern of high tadpole levels and low adult(More)
An optical fiber is mounted on a precision spindle, that can be indexed as well as speed controlled, in readiness for precision microlens grinding. A cluster of piezoelectric actuators, mounted on the spindle itself, carry out the crucial task of centering the fiber. Together with the indexing carried out using the spindle drive motor, the piezoelectric(More)
