Percy Lavon Julian (April 11, 1899 – April 19, 1975) was an American research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants. He was the first to synthesize the natural product physostigmine, and a pioneer in the industrial large-scale chemical synthesis of the human hormones progesterone and testosterone from plant sterols such as stigmasterol and sitosterol. His work laid the foundation for the steroid drug industry’s production of cortisone, other corticosteroids, and birth control pills.
Julian received more than 130 chemical patents. He was one of the first African-Americans to receive a doctorate in chemistry. He was the first African-American chemist inducted into the National Academy of Sciences, and the second African-American scientist inducted (behind David Blackwell) from any field.

post-mitotic:

acute megakaryoblastic leukemia
this subset of acute leukemia affects the megakaryoblastic lineage, which explains the multinucleation and cytoplasmic processes of these cancerous cells — in a non-pathological situation, however, pieces of mature megakaryocytes pinch off to form platelets
cancerous megakaryoblasts are also related to the pokemon, Gastly
I’d advise against catching this one though

Top picture: 1987 Dr. Zbigniew Religa monitors his patient’s vitals after a 23 hour long heart transplant surgery. His assistant is asleep in the corner. Photograph taken by James Stanfield.

Bottom picture: His patient who survived and actually went on to outlive Dr. Religa.

Dr. Religa was also the first surgeon to graft an artificial valve using materials from human corpses. He lead a team that completed the first successful heart transplantation in Poland. Him and his team obtained the Brusseis Eureka award for developing an implantable pump for a pneumatic heart assistance system.
