Tetrahymena cilia contain a three-headed 22S (outer arm) dynein and a single-headed 14S dynein. In this study, we have employed an in vitro assay of microtubule translocation along dynein-coated glass surfaces to characterize the motile properties of 14S dynein, 22S dynein, and proteolytic fragments of 22S dynein. Microtubule translocation produced by intact 22S dynein and 14S dynein differ in ...

The purpose of this study was to examine the female-headed household empowerment based on social-cognitive career counseling and its impact on promoting their career self-efficacy and future orientation (time perspective, anticipation of future consequences, planning ahead). This quasi-experimental research had a pretest-posttest control group follow-up design. The statistical population of the...

Bar-headed geese (Anser indicus) fly at high altitudes during their migration across the Himalayas and Tibetan plateau. However, we know relatively little about whether rearing at high altitude (i.e. phenotypic plasticity) facilitates this impressive feat because most of what is known about their physiology comes from studies performed at sea level. To provide this information, a comprehensive ...
