Transient neonatal cyanosis associated with a new Hb F variant: Hb F viseu.
Neonatal cyanosis in healthy newborns can be associated either with methemoglobin due to cytochrome b5 reductase deficiency or to M-hemoglobin, a group of hemoglobin variants resulting from mutations in the globin chain genes. We report the clinical case of a neonate with cyanosis and normal cardiac and respiratory function. At birth the hematological parameters were normal; however, the methem...
متن کاملFactors regulating Hb F synthesis in thalassemic diseases
BACKGROUND: The thalassemic syndromes originate from mutations of the globin genes that cause, besides the characteristic clinical picture, also an increased Hb F amount. It is not yet clear if there are more factors, besides the beta globin genotype, determining the Hb F production. We have tried to find out if there are relations between total Hb and Hb F, between erythropoietin (Epo) and Hb ...
متن کاملHb F production of endogenous colonies of polycythemia vera.
Fetal hemoglobin was studied in endogenous colonies produced in plasma clot and methylcellulose cultures of circulating progenitors from patients with polycythemia vera (PV). Analysis of globin chain synthesis showed that gamma chains constituted from 13% to 42% of the non-alpha chains produced in cultured cells, whereas from 27% to over 50% of the endogenous colonies contained Hb F, as indicat...
متن کاملD6/ackr2
IN THE BEGINNING . . . Very much in keeping with the name of the chemokine receptor subfamily to which D6 belongs, the majority of my research in the field of chemokine biology has been “atypical” in the sense that it has rarely focused on classical immunological roles for these molecules. Indeed, the story behind the discovery of D6 starts from an unusual research perspective! In 1988, I was e...
متن کاملD6-branes and torsion
The D6-brane spectrum of type IIA vacua based on twisted tori T̃ 6 and RR background fluxes is analyzed. In particular, we compute the torsion factors of Hn(T̃ 6,Z) and describe the effect that they have on D6-brane physics. For instance, the fact that H3(T̃ 6,Z) contains ZN subgroups explains why RR tadpole conditions are affected by geometric fluxes. In addition, the presence of torsional (co)ho...
