Sickle Hemoglobin Fiber Kinetics Revealed by Optical Pattern Generation

Sickle cell-hemoglobin C disease. Quantitative determination of iron kinetics and hemoglobin synthesis.

Kinetics of the carbamylation of the amino groups of sickle cell hemoglobin by cyanate.

The NH2-terminal valine residues of both chains of oxyhemoglobin S are carbamylated 50 to 100 times faster at pH 7.4 than the a-NH2 groups of the lysine residues of the protein up to a level of 1 carbamyl group per hemoglobin molecule. The pseudo-first order rate constants for the carbamylation of the NHz-terminal residues of carbonmonoxyhemoglobins A and S are identical for the proteins either...

An unusual pattern of neutrophil kinetics in sickle cell anemia.

Blood neutrophil kinetics were studied withwith DF32P in patients with sickle cell anemia. Neutrophil concentration in venous blood samples and the size of the circulating granulocyte pool (CGP) were high normal or abnormally high in all patients. The total blood granulocyte pool (TBGP) was not increased to the same degree as the CGP so that in part, the neutrophilia associated with sickle cell...

Weight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)

The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...

Materials Development for Next Generation Optical Fiber

Optical fibers, the enablers of the Internet, are being used in an ever more diverse array of applications. Many of the rapidly growing deployments of fibers are in high-power and, particularly, high power-per-unit-bandwidth systems where well-known optical nonlinearities have historically not been especially consequential in limiting overall performance. Today, however, nominally weak effects,...
