Additionally, correlations according to Hp phenotypes revealed strong association between ceruloplasmin ferroxidase activity and serum ferritin in patients with Hp 2-2 phenotype and not in the others (r=0.331, p<0.05).
Here, kinetics and thermodynamics of fluoride and azide binding to ferric human Hb (Hb(III)) complexed with the human Hp phenotypes 1-1 and 2-2 (Hp1-1:Hb(III) and Hp2-2:Hb(III), respectively) are reported (pH 7.0 and 20.0 °C).
There were no significant differences in malaria parasite densities among Hp phenotypes but children with Hp 2-2 had lower number of clinical malaria episodes (P=0.045).
In summary, we could not establish a correlation between Hp phenotype and oocyte number or IVF outcomes though the Hp2-2 phenotype may be protective against mechanical factor infertility.
Here, kinetics and thermodynamics of cyanide, thiocyanate and imidazole binding to ferric human Hb (Hb(III)), Hb(III) dimers complexed with the human Hp phenotypes 1-1 and 2-2 (Hp1-1:Hb(III) and Hp2-2:Hb(III), respectively), and α(III) and β(III) chains are reported and analyzed in parallel with fluoride and azide binding properties (at pH 7.0 and 20.0 °C).
We propose that previous conflicting results between Hp phenotypes/genotypes and malaria susceptibility may be explained by differing prevalence of the A-61C SNP in the populations studied, which we found to be highly associated with the Hp2 allele.
