Treatment of Hypercalcemic Hyperparathyroidism After Kidney Transplantation Is Associated With Improved Allograft Survival

Rongzhi Wang, Rhiannon Deierhoi Reed, Griffin Price, Peter J. Abraham et autres

BACKGROUND: Hyperparathyroidism (HPT) and malignancy are the most common causes of hypercalcemia. Among kidney transplant (KT) recipients, hypercalcemia is mostly caused by tertiary HPT. Persistent tertiary HPT after KT is associated with allograft failure. Previous studies on managing tHPT were subjected to …

Nonlinear-optical studies of molybdenum metal organics

Tianbao Zhai, D. C. Gale, Gary M. Gray, Christopher M. Lawson et autres

We have measured the third-order susceptibility, X((3)), versus concentration for a number of molybdenum-based metal-organic complexes in solution, using independent degenerate four-wave mixing and Z-scan techniques. Good agreement was obtained between the degenerate four-wave mixing and Z-scan measurements. The variation of X((3)) …

A degenerate-four-wave-mixing apparatus for the study of materials in solution

David C. Gale, G. E. Burgess, Tianbao Zhai, Marshall Lewis

A degenerate-four-wave-mixing apparatus is described, with novel data acquisition, and sample handling techniques. Particular attention is paid to methods of noise reduction and elimination. Four-wave mixing is performed with Nd:YAG laser light, at both 532 and 1064 nm, and with a pulse …

Wideband Microstrip Ring Radiator

Marshall Lewis, J. F. Toth

Abstract : A description is given of a wideband mircostrip antenna element suitable for use in an array. Several configuration which operate over a relatively wide band of frequencies (> 10%) are identified. The theory of operation, an analytical model, and experimental …
