A master of expressionist portraits and figure studies, he enjoyed little success during his brief career. Elegantly lengthened mask-like faces and bodies with simplified idealized features were hallmarks of his style, although he also provoked controversy by his stark inclusion of pubic hair in his nudes. Impoverished and suffering from terminal tuberculosis in his early thirties, he sank deeper into alcoholism although he continued to paint. He had one serious romantic interest, Jeanne Hébuterne, a young model who became his fiancé at the end of his life, despite the objections of her parents. Here he depicts her during her pregnancy in a white chemise (1919). The article by Marchese addressing Lewis antibodies in pregnancy is included in this issue.

A further 7 units of FUT1 and ABO encode enzymes that synthesize H, A, and B RBCs, all group O, D+, and 18 group A and 4 group O units in mesodermal and hematopoietic tissues that are therefore of apheresis platelets were transfused post-transplant, within intrinsic to the RBC. FUT2 and FUT3, together with ABO, are a 1-month period.
