This is a review of several new approaches developed at or adopted by the Cooperative Prostate Cancer Tissue Resource (CPCTR) to resolve issues involved in tissue microarray (TMA) construction and use. CPCTR developed the first needle biopsy TMA, allowing researchers to obtain 200 or more consecutive cancer sections from a single biopsy core. Using(More)
In this paper, we address the pursuit/evasion problem of capturing an omnidirectional evader using a Differential Drive Robot (DDR) in an obstacle-free environment. The goal of the evader is to keep the pursuer farther than the capture distance for as long as possible and for the pursuer the goal is to capture the evader as soon as possible. In [1] an(More)
The development of dominant follicles requires the parallel growth of a vascular network, regulated by VEGF and its receptors VEGFR-1 and VEGFR-2. Here, we demonstrate the presence of mRNA for the soluble forms of VEGFR-1 and VEGFR-2 by RT-PCR and the respective proteins by Western blot, in bovine dominant follicles. The 3' end of the mRNA coding region and(More)
