Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within 24 hours.
Cryopreservation of Red blood cells (RBCs) can be done with a long time span of usability of 10 years. Glycerol safeguards RBCs during freezing and defrosting, yet it can cause hemolysis if it is not washed off or eliminated before transfusion. When a unit has been deglycerolized, the shelf life of RBCs in an open system is only 24 hours, bringing about sporadic utilization of Frozen RBCs from the outset of the procedure or in close system cases it is up to 14 days.

Mesozoic era
Explanation:
The mesozoic is but one of the eras on the geologic timescale. This era spanned between 252 - 66million years ago.
It is bounded by two major mass extinction events. The Permian- Triassic extinction wiped about 90% of a life on earth. The other extinction is the Cretaceous-Paleogene which resulted in the demise of the dinosaurs.

The mesozoic is known as the age of reptiles and dinosaurs.
The first flowering plants came towards the end of the era. The era was intially dominated by conifers.
This is also the age of the first birds.
