postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Polymerization of Recombinant Hemoglobin F yE6V and Hemoglobin F yE6V, yQ87T Alone, and in Mixtures With Hemoglobin S
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...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولPolymerization and instability of a recombinant hemoglobin containing valine beta 7.
A recombinant hemoglobin containing Val beta 7 (Hb beta E7V) was engineered and expressed in yeast to evaluate amino acid specificity of the Glu beta 6-->Val mutation (Hb beta E6V) in promoting polymer formation of deoxyhemoglobin. The purified CO Hb beta E7V migrated as a single band on electrophoresis with a slightly decreased positive charge compared with CO Hb S. The oxygen affinity of Hb b...
متن کاملContribution of histidine residues to the conformational stability of ribonuclease T1 and mutant Glu-58----Ala.
The pK values of the histidine residues in ribonuclease T1 (RNase T1) are unusually high: 7.8 (His-92), 7.9 (His-40), and 7.3 (His-27) [Inagaki et al. (1981) J. Biochem. 89, 1185-1195]. In the RNase T1 mutant Glu-58----Ala, the first two pK values are reduced to 7.4 (His-92) and 7.1 (His-40). These lower pKs were expected since His-92 (5.5 A) and His-40 (3.7 A) are in close proximity to Glu-58 ...
