In the present study, we exposed 53 animals from 23 different species of amphibians and reptiles to microgravity (mug). This nearly doubles the number of amphibians and reptiles observed so far in mug. The animals were flown on a parabolic flight, which provided 20-25s of mug, to better characterize behavioral reactions to abrupt exposure to mug. Highly(More)
Though the African clawed frog (Xenopus laevis) is the most commonly used amphibian in biological research, there are no standard protocols for the husbandry of this species. With the goal of developing optimal conditions for raising these frogs, the authors assessed the effects of available cover and feeding schedule on post-metamorphic growth and behavior(More)
AIM The rheological properties of erythrocytes are impaired in diabetes mellitus, especially because of changes in their membrane lipid composition.The aim of this study was to determine and examine the relationship between red blood cell (RBC) membrane and serum lipid composition in type II diabetes subjects with and without nephropathy.
