Zero-link polymerized hemoglobin (OxyVitaHb) stabilizes the heme environment: potential for lowering vascular oxidative stress.

A study was conducted to compare the resistance to heme exposure between myoglobin, bovine hemoglobin, and OxyVitaHb (zero-link-hemoglobin-polymer). The rate of release of heme-iron is related to the tissue oxidative stress that can elicit deleterious effects in clinical uses of blood substitutes. Experimental work has focused on the unfolding of hemoglobin molecules, resulting in heme loss, by using urea as a denaturant and analyzing the Soret spectral region.

Incidence of haemoglobinopathies detected through neonatal screening in the United Arab Emirates.

In January 2002, a pilot programme of neonatal screening for sickle cell disease was launched in the United Arab Emirates (UAE) in 3 districts of Abu Dhabi emirate. This paper reports the incidence of sickle cell diseases, other haemoglobinopathies and haemoglobinopathy carriers over a 12-month period using high performance liquid chromatography as a primary screening method. The overall incidence of sickle cell disease among 22 200 screened neonates was 0.
