Intense exercise training can induce low concentrations of hemoglobin, which may be followed by maladaptation. Therefore, it is important for athletes to prevent hemoglobin during intense training. In this study, we explored whether different protocols intermittent hypoxic exposure (IHE, normobaric hypoxia, 14.5% O 2 ) could the training-induced reduction in concentration rats. Six-week-old mal...

Haptoglobin forms a stable, irreversible complex with hemoglobin. The H chain of haptoglobin, which is the subunit that binds hemoglobin, shows strong sequence homology with the serine protease family. This raises the question of whether hemoglobin binds to the protease-like active site pocket of H chain as the protease inhibitors do with serine proteases. This question can be tested by binding...

Because veal lean color continues to be a primary factor that determines veal carcass value and is typically assessed by subjective means, it is important to explore objective methods for color assessment. Objective and subjective evaluations of veal flank and breast lean color were compared as predictors of longissimus lean color at 24 h postmortem. One hundred fifty special-fed Holstein veal ...

We describe a sensitive, accurate automated method for the simultaneous measurement of methemoglobin and total hemoglobin in blood. The method can be used for either continuous in vivo monitoring or intermittent sampling at a rate of 20/h. Standardization procedures are described, in which human blood treated with sodium nitrite is used. Repeatability of methemoglobin and total hemoglobin measu...

We have devised a rapid and convenient method of eliminating the contribution of labile glycosylated hemoglobin in the hemoglobin A1 assay. The procedure requires a 30-min incubation of erythrocytes in 30 mM semicarbazide and 12 mM aniline (pH 5, 38 degrees C). This chemical means of eliminating the labile fraction is as effective as a 14-h incubation in isotonic saline as measured with high-pr...

We have combined hyperspectral imaging with spectral domain optical coherence tomography (SDOCT) to noninvasively image changes in hemoglobin saturation, blood flow, microvessel morphology, and sheer rate on the vessel wall with tumor growth. Changes in these hemodynamic variables were measured over 24 h in dorsal skin fold window chamber tumors. There was a strong correlation between volumetri...

Dihydroartemisinin and other artemisinin derivatives are relatively ineffective against Plasmodium falciparum infecting alpha-thalassemic erythrocytes, namely hemoglobin (Hb) H or HbH/Hb Constant Spring erythrocytes, as compared with those infecting genetically normal erythrocytes. The variant erythrocytes accumulate radiolabeled dihydroartemisinin to a much higher extent than the normal ones, ...
