Concise review: how do red blood cells born, live, and die?

The average life cycle of a human RBC is approximately 120 days. Generally, by this point, the cell is worn out and damaged. RBCs pass through both the spleen and liver, where specialised immune cells called macrophages are found.

Neonatal haemoglobinopathy screening in Spain.

The prevalence of variant haemoglobins in Spain is increasing as a result of recent African immigration. Of the 19 regions of Spain, 13 have more than 1% of residents of African origin or ethnicity. Haemoglobinopathy prevalence is heterogeneous.

New haplotype for the Glu104Asp mutation in triose-phosphate isomerase deficiency and prenatal diagnosis in a Spanish family.

First-trimester prenatal diagnosis was undertaken by chorionic villus DNA analysis in a Spanish family with the inherited Glu104Asp triose-phosphate isomerase deficiency. The fetus was heterozygous for the mutation and therefore predicted to be clinically unaffected. To investigate the evolutionary origin of this mutation, studies were conducted on the intragenic 2262A/G polymorphism and the CD4 pentameric tandem repeat marker.
