Bone marrow biopsies of 720 patients with multiple myeloma (MM) were investigated from 1968-1989. Histologic variables were correlated with clinical parameters and survivals to determine prognostic factors. In 207 of these patients initial levels of serum beta 2 microglobulin (SB2M) were also measured for prognostic evaluation. Four tumour growth patterns(More)
We describe a monolithic (fully fused), 1.2-kW, Yb-doped fiber laser with single-mode beam quality. This laser employs a new generation of 100-W, high-brightness, fiber-coupled pump sources based on spatially multiplexed single emitters and a simple, end-pumped design for high efficiency, reliability, and environmental stability.
We report efficient amplification of an external cavity diode laser in the 1.06-microm range. The diode laser radiation is coupled into a Nd-doped silica fiber. The fiber is pumped by a diode array with up to 6.15 W of power. After a single pass of the seed radiation through the fiber amplifier, we observe up to 1.74 W of single-mode, narrow-linewidth laser(More)
In a retrospective and prospective follow-up study from 1968 to 1989, bone marrow biopsy specimens, serum beta-2-microglobulin (SB2M) levels, and the clinical features of 251 patients with multiple myeloma (MM) and 28 patients with monoclonal gammopathy of undetermined significance (MGUS) were investigated. The main histologic variables (tumor cell type,(More)
