Discrimination of hemoglobins with subtle differences using an aptamer based sensing array.

Chemical Communications, 2015
Discrimination of hemoglobins with subtle differences was achieved using an aptamer based sensing array. Linear discriminant analysis (LDA) showed that the sensing array can discriminate human hemoglobins from hemoglobins of different species.

The redox activity of hemoglobins: from physiologic functions to pathologic mechanisms.

Antioxidants and Redox Signaling, 2010
Pentacoordinate respiratory hemoproteins such as hemoglobin and myoglobin have evolved to supply cells with oxygen. However, these respiratory heme proteins are also known to function as redox enzymes, reacting with compounds such as nitric oxide and ...

Hydroxylamine reduction to ammonium by plant and cyanobacterial hemoglobins.

Biochemistry, 2011
Plants often face hypoxic stress as a result of flooding and waterlogged soils. During these periods, they must continue ATP production and nitrogen metabolism if they are to survive.

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.

The organization of hemoglobin in erythrocytes containing hemoglobin A or hemoglobin C

Canadian Journal of Physiology and Pharmacology, 1970
Red cells containing hemoglobin C have been shown to behave as if they are more rigid than normal cells that contain hemoglobin A. Under some conditions the former cells contain inclusions that appear to be crystalline. This study shows, by X-ray scattering and diffraction, that the inclusions are crystalline.

Trema and parasponia hemoglobins reveal convergent evolution of oxygen transport in plants.

Biochemistry, 2010
All plants contain hemoglobins that fall into distinct phylogenetic classes. The subset of plants that carry out symbiotic nitrogen fixation expresses hemoglobins that scavenge and transport oxygen to bacterial symbiotes within root nodules.

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.

The primary structures of alpha and beta chains of adult hemoglobin of the Japanese monkey (Macata fuscata fuscata). Biochemical studies on hemoglobins and myoglobins. XI.

International journal of peptide & protein research, 2009
Amino acid sequence of the tryptic peptides from the α and β chains of adult hemoglobin of the Japanese monkey were analyzed by partial hydrolyses with enzymes, the DNP method, PTC method and others after the isolation and purification of these peptides.

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.
