Successful Pregnancy and Delivery after Frozen-thawed Embryo Transfer Following the Third Discontinuation of Tyrosine Kinase Inhibitor in a Woman with Chronic Myeloid Leukemia.

Assisted reproductive technology is a viable option for pregnant women with chronic myeloid leukemia. We herein report the case of a patient who underwent successful fertility treatment with frozen embryo preservation at 36 years of age, followed by embryo transfer at 39 years of age, thus resulting in pregnancy and delivery after a third discontinuation of tyrosine kinase inhibitors (TKIs). Despite the difficulty of long-term TKI withdrawal, the patient's strong desire for a baby led to a successful pregnancy and delivery with no apparent deformities or abnormalities.

[Primary mediastinal large B-cell lymphoma complicated with myotonic dystrophy].

A 39-year-old woman with myotonic dystrophy (DM) presented with syncope and was diagnosed with primary mediastinal large B-cell lymphoma, clinical stage IA. PET-CT revealed an upper mediastinal mass with high FDG uptake (SUVmax, 14.8).

Formulation of non-linear viscoelastic-viscoplastic constitutive equation for polyamide 6 resin.

In this study, a non-linear viscoelastic-viscoplastic constitutive equation for polyamide 6 (PA6) is formulated and a new model is suggested for the viscoplastic part of the equation. The suggested model is empirical but can accurately predict the viscoplastic strain. In this study, creep and recovery tests are conducted to evaluate the viscoplastic strain.
