During mitosis, sister chromatids are separated by the action of the mitotic spindle. The mitotic spindle attaches to chromosomes at centromeres through a protein complex called the kinetochore. While ~100 proteins have been identified at kinetochores and centromeres, the function of most is poorly understood.
The centromere protein, CENP-T (Centromere...

Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

AN ABSTRACT OF THE DISSERTATION OF

Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
A promising formulation of glipizide comprising compression of four-layer coated beads into tablets which has advantages of providing a lag time (~ 2 hours) before drug release, retaining sustained-release characteristics, and providing approximately zero-order drug release, with drug release nearly independent of paddle speeds of 50 and 100 rpm during...

Many populations consist of individuals that differ substantially in their diets. Quantification of the magnitude and temporal consistency of such intraspecific diet variation is needed to understand its importance, but the extent to which different approaches for doing so reflect instantaneous vs. time-aggregated measures of individual diets may bias inferences....

All ecosystems are subjected to chronic disturbances, such as harvest, pollution, and climate change. The capacity to forecast how species respond to such press perturbations is limited by our imprecise knowledge of pairwise species interaction strengths and the many direct and indirect pathways along which perturbations can propagate between species....
