Discrimination by Black Males Revisited:

Abstract

In an earlier article on faculty salary discrimination at a Southern, historically black, public university (SHBU), the authors presented evidence of salary discrimination by black males against other race‐sex groups (Riggs and Dwyer 1995). The authors now contrast SHBU's salary model with the model of Riggs and Dwyer and apply the latter to new data to determine whether SHBU eliminated race and sex discrimination in faculty salaries. After equity adjustments, the evidence suggests that SHBU has eliminated the salary discrimination found by Riggs and Dwyer in their earlier study.

Structural and functional properties of hemoglobins from unicellular organisms as revealed by resonance Raman spectroscopy

“…The quaternary assemblage of the Hb subunits into its functional structure is remarkably diverse, ranging from the monomeric Hbs of bacteria to the gigantic 144-subunit Hb of annelid [10,12]. The quaternary interactions play an important role in modulating the ligand binding affinity of Hb.…”

“…In vertebrates, Hb serves as an oxygen carrier that transports oxygen to local tissues through the vascular system. It was recently discovered that, in addition to vertebrates, Hb is also widely distributed among prokaryotes, eukaryotes, plants and invertebrates (see [10][11][12][13][14][15][16][17][18] and the Hb reviews in this issue). The physiological functions of these new Hbs are much more diverse.…”

Mass Spectrometry in the Study of Hemoglobin: from Covalent Structure to Higher Order Assembly

“…Once hemolysis has occurred and hemoglobin is released from within the erythrocyte, where in mammals its concentration is on the order of 5 mM [83], Hb tetramers can dissociate to heterodimers. In dilute solutions, dissociation can proceed even further to monomeric globin species [84].…”

Hemoglobina extracelular gigante de Glossoscolex paulistus: um extraordinário sistema supramolecular hemoproteico

“…111 Vários trabalhos na literatura têm buscado contribuir na química de hemoproteínas correlacionando as propriedades do complexo ferro-porfirínico com as características espaciais de toda a sub-unidade. 6 Em resumo, os estados de organização da hemoglobina íntegra são dependentes tanto do estado de oxidação do centro de coordenação da porfirina como dos ligantes axiais, 62 o que é corroborado, inclusive, por trabalhos anteriores de nosso grupo envolvendo a hemoglobina de Glossoscolex paulistus. [126][127][128] Riggs e colaboradores 62 têm proposto que hemoglobinas de invertebrados em geral apresentam mudanças conformacionais dependentes dos ligantes, com mecanismos de cooperatividade diferentes daqueles encontrados nos vertebrados.…”
