Pancytopenia and Myelodysplastic Changes in Aceruloplasminemia: A Case with a Novel Pathogenic Variant in the Ceruloplasmin Gene.

A 72-year-old Japanese woman suffered from mild pancytopenia 3 years before her initial hospitalization. On admission, the levels of trace elements, particularly copper, and ceruloplasmin were significantly decreased in her blood serum. Abdominal lymphadenopathy and bone marrow dysplasia were detected.

Isolated Pancreatic Myeloid Sarcoma Associated with t(8;21)/RUNX1-RUNX1T1 Rearrangement.

No valid treatment for isolated myeloid sarcoma (IMS) has yet been established, and no thorough genetic examinations have been performed because of its low incidence and unique manner of development. We herein report a 34-year-old man with pancreatic IMS with t(8;21)/RUNX1-RUNX1T1 rearrangement. He was treated with high-dose cytarabine followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Long-term cryopreservation of mouse sperm.

The objective was to determine if mouse sperm can maintain their fertilizing ability after being frozen for >10 y and whether the offspring derived from these sperm had normal fertilizing ability and phenotype. We cryopreserved sperm from six strains of mice (C57BL/6J, DBA/2N, BALB/cA, C3H/HeJ, B6D2F1 and B6C3F1) in a solution containing 18% (w/v) raffinose and 3% (w/v) skim milk, and preserved them in liquid nitrogen for >10 y. To assess the normality and fertilizing ability of these sperms, they were thawed and used for in vitro fertilization of oocytes of the same strains.
