FAB classification

French-American-British classification of acute leukemia Hematology A schema that divides acute leukemias into lymphoid–ALL or myeloid–AML cell lines; of childhood ALL, 70% are predominantly L1, 27% are L2, and 3% or less are L3 or Burkitt cell type, in adults with ALL, 30% are L1, 65% are L2, and 5% are L3

FAB classification, acute leukemias

Acute lymphocytic leukemia (ALL)

L1 Small monotonous lymphocytes

L2 Mixed L1- and L3-type lymphocytes

L3 Large homogeneous blast cells

Acute myeloid leukemia (AML)

M1 Myeloblasts without maturation

M2 Myeloblasts with maturation (best AML prognosis)

M3 Hypergranular promyelocytic leukemia (faggot cells)

M3V Variant, microgranular promyelocytic leukemia

M4 Myelomonocytic leukocytes

M5 Monocytic, subtype

a. Poorly differentiated monocytic leukemia

b. Well differentiated monocytic leukemia

M6 Erythroleukemia/DiGuglielmo syndrome

M7 Megakaryocytic leukemia Pleomorphic undifferentiated cells with cytoplasmic blebs; myelofibrosis or ↑ BM reticulin; positive for platelet peroxidase antifactor VIII

This article describes a semi-empirical [12-13] study on the thermodynamics involved in the synthesis of o-6, m-7 and p-8.

Equilibrium constants and reaction yields follow the order o-6 greater than m-7 greater than p-8 which are given in Table 4.

Thermodynamics of synthesis of new phenoxazine derivatives

A new M-7 pedestal now allows Soldiers to mount machine guns and grenade launchers in the rear of their HMMWV's open cargo bed to improve convoy protection.

The Joint Manufacturing and Technology Center at Rock Island Arsenal has been contracted to produce 4,500 of the new M-7 pedestals.

The M-7 pedestal allows Soldier to mount the M-249, M-240B, and M2 machine guns and the MK-19 grenade launcher in the rear cargo bed of M998 HMMWV.
