Considerable interest is currently focused on fish haemoglobins in order to identify the structural basis for their diversity of functional behavior. Hoplosternum littorale is a catfish that presents bimodal gill (water)/gut ...

Red cell haemoglobin is the fundamental oxygen-transporting molecule in blood, but also a potentially tissue-damaging compound owing to its highly reactive haem groups. During intravascular haemolysis, such as in malaria ...

Glossoscolex paulistus is a free-living earthworm encountered in south-east Brazil. Its oxygen transport requirements are undertaken by a giant extracellular haemoglobin, or erythrocruorin (HbGp), which has an approximate ...

Oxygen uptake by erythrocytes exposed to t‐butyl hydroperoxide (t‐BHP) exhibited an induction period. The rate of oxygen consumption can be reduced by antioxidants and blood plasma. The induction time was not appreciably ...

Allometry of haematological parameters (haematocrit, erythrocyte number, mean cell volume and haemoglobin concentration) of Basilichthys australis, suggested that small individuals and juveniles had larger red blood cells, ...
