Cell proliferation in prostate cancer patients with lymph node metastasis: a marker for progression.
The biological aggressiveness of lymph node-positive prostate cancer is closely linked to cancer volume in nodal metastases. We evaluated MIB-1 (Ki-67) labeling index and bcl-2 expression in primary cancer and matched nodal metastases from 138 node-positive patients treated with radical prostatectomy and bilateral pelvic lymphadenectomy between 1987 and 1992 at the Mayo Clinic. One hundred twen...
Angles subtended at the second nodal point of eye (NP2) are approximately same as input visual angles over a very large angular range, despite being paraxial lens property. Raytracing using an average pseudophakic showed that criterion was only valid up to about 10°, and linear relationship due instead cornea initially creating chief ray exit pupil 0.83 times values for this particular eye, the...
the influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘bianca’ and ‘el torro’. third, fourth and fifth nodal explants were cultured on the modified ms medium supplemented with 1.0 and 5.0 mg/l ba. in both the cultivars, higher rate of proliferation (‘bianca’ 3.75; ‘el torro’ 2.65) were obtained from the explants distal to the a...
This paper proposes an algorithm for transmission cost allocation (TCA) in a large power system based on nodal pricing approach using the multi-area scheme. The nodal pricing approach is introduced to allocate the transmission costs by the control of nodal prices in a single area network. As the number of equations is dependent on the number of buses and generators, this method will be very ti...
Recently, the Adaptive Delaunay Tessellation (Adt) was introduced in the context of computational mechanics as a tool to support Voronoi-based nodal integration schemes in the finite element method. While focusing on applications in mechanical engineering, the former presentation lacked rigorous proofs for the claimed geometric properties of the Adt necessary for the computation of the nodal in...
