Spectrophotometry of Hemoglobin and Hemoglobin Derivatives

1983
Publisher Summary This chapter presents a discussion of spectrophotometry of hemoglobin and hemoglobin derivatives. Many special photometers (hemoglobinometers, oximeters, etc.) presently available for the determination of hemoglobin and hemoglobin derivatives are mentioned only incidentally.

Recombinant hemoglobin A produced in transgenic swine: structural equivalence with human hemoglobin A.

Artificial cells, blood substitutes, and immobilization biotechnology, 1994
Recombinant human hemoglobin A produced by coexpressing human alpha and beta globin genes in swine, and purified from the lysate of transgenic swine has been subjected to detailed protein chemical analysis.

Biocompatible and biodegradable polymersome encapsulated hemoglobin: a potential oxygen carrier.

Bioconjugate chemistry, 2008
This work describes the development of polymersome-encapsulated hemoglobin (PEH) self-assembled from biodegradable and biocompatible amphiphilic diblock copolymers composed of poly(ethylene oxide) (PEO), poly(caprolactone) (PCL), and poly(lactide) (PLA).

OBSERVATIONS ON HEMOGLOBIN "PYLOS": THE HEMOGLOBIN PYLOS-HEMOGLOBIN S COMBINATION.

The Journal of laboratory and clinical medicine, 1963
Abstract Two cases, the first reported in the medical literature, of association of the hemoglobin "Pylos" anomaly and hemoglobin S are discussed. The clinical picture and laboratory findings are presented, and the difficulty of accurate diagnosis by the routine procedures of hemoglobin analysis is emphasized. The findings are discussed in relation to

Ontogeny of hemoglobins: Evidence for hemoglobin M

Developmental Biology, 1974
Abstract A new autosomal codominant hemoglobin mutation alters hemoglobin M of the primitive red cell line and hemoglobin D found in definitive cells. That Hb M and Hb D are altered by the same gene mutation supports the idea that Hb M shares a polypeptide chain with Hb D.

Unstable Hemoglobins, Hemoglobins with Altered Oxygen Affinity, and M-Hemoglobins

Pediatric Clinics of North America, 1980
Most patients with chronic Heinz body anemia do not require treatment. Dietary folic acid supplementation is recommended when hemolysis is chronic and severe. During infection, patients should be observed carefully because of the possibility of aplastic or hemolytic crises.

Arenicola marina extracellular hemoglobin: a new promising blood substitute.

Biotechnology Journal, 2006
The need to develop a blood substitute is now urgent because of the increasing concern over Europe's BSE outbreak and the worldwide HIV/AIDS epidemic, which have cut blood supplies.

The hemoglobins of Artemia salina. V. Genetic variation in hemoglobin 1, hemoglobin 2, and hemoglobin 3 [PDF]

Biochemical Genetics, 1977
Electrophoretic mobilities of three hemoglobins (Hb1, Hb2, and Hb3) were studied in 15 populations of brine shrimps. Genetic segregation data support the model that Hb2 contains n alpha-polypeptides and n beta-polypeptides; Hb1 contains 2n alpha-polypeptides- Hb3 contains neither alpha- nor beta-polypeptides.

Targeted O2 delivery by low-P50 hemoglobin: a new basis for O2 therapeutics.

American Journal of Physiology. Heart and Circulatory Physiology, 2003
To assess O2 delivery to tissue by a new surface-modified, polyethylene glycol-conjugated human hemoglobin [MP4; Po2 at 50% saturation of hemoglobin (P50); 5.4 mmHg], we studied microcirculatory hemodynamics and O2 release in golden Syrian hamsters ...

On the relationship of hemoglobin oxidation with the conformation of hemoglobin

Experientia, 1979
The rate of hemoglobin oxidation by various oxidants was studied under aerobic and anaerobic conditions, and the mechanism of hemoglobin oxidation was discussed in relation to the conformation of hemoglobin.
