In this paper, we obtain the explicit limit value of the Teichmüller distance between two Teichmüller geodesic rays which are determined by Jenkins-Strebel differentials having a common end point in the augmented Teichmüller space. Furthermore, we also obtain a condition under which these two rays are asymptotic. This is similar to a result of Farb and Masur.

To clarify the role of gammaN-terminal Gly, gamma5 Glu, and gamma143 Ser in 2,3-biphosphosphoglycerate (BPG) binding to fetal hemoglobin (Hb F), we engineered and produced normal human Hb F and two Hb F variants (Hb F gammaG1V, gammaS143H, and Hb F gammaG1V, gammaE5P, gammaS143H) using a yeast expression system and then compared their oxygen-binding properties with those of native human Hb F an...

background: hemoglobin (hb) and hematocrit (hct) have been used routinely in the diagnosis of neonatal anemia and polycythemia.   objective: to measure the cord blood hb and hct and to determine their association with maternal hb and hct.   methods : 170 healthy neonates born through normal vaginal delivery with gestation age of 37-42 wks and birth weight of 2.5-4 kg, and their mothers were inc...

Human hemolysate contains several minor components designated Hb A,,, Hb Alh, Hb A,,, which are post-translational modifications of the major hemoglobin component A,,. Individuals with diabetes mellitus have elevated levels of Hb A,,, a hemoglobin modified with a glucose moiety at the NH, terminus of each /3 chain. A new chromatographic technique using Bio-Rex 70 is described which not only all...

To further understand determinants for Hemoglobin (Hb) S polymerization, as well as the inhibitory mechanism of Hb F on Hb S polymerization, Hb F variants containing Val-* (Hb F yE6V) or Val-*, Thr-y87 (Hb F yE6V. yQ87Tj were expressed in yeast. The oxy form of Hb F yE6V was about 10-fold less stable to mechanical agitation than native oxy Hb F, which is similar to stability differences compari...

Hemoglobin A2 (Hb A2) and hemoglobin F (Hb F) are important analytes in the diagnosis and follow up of Hb diseases. We evaluated a new capillary zone electrophoresis (CZE) kit for Hb A2 and Hb F measurements. The imprecision ranged from 3% to 6% for Hb A2 and Hb F at physiological and pathological concentrations. The method compared well with cation-exchange HPLC for Hb A2 and Hb F and with ani...
