Successful Treatment of a Patient Presenting with Simultaneous Diffuse Large B-Cell Lymphoma and Hodgkin Lymphoma: A Case Report.

BACKGROUND Simultaneously occuring diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL) is extremely rare. Generally, patients with CD20-positive DLBCL receive rituximab, cyclophosphamide, vincristine, doxorubicin, prednisone (R-CHOP) regimen, while those with HL receive brentuximab vedotin, doxorubicin, vinblastine, dacarbazine (A-AVD) regimen as first-line therapy. Establishing a strategy for treating both lymphoma subtypes concurrently is thus very difficult.

Expanding Horizons in Quantum Chemical Studies: The Versatile Power of MRSF-TDDFT.

ConspectusWhile traditional quantum chemical theories have long been central to research, they encounter limitations when applied to complex situations. Two of the most widely used quantum chemical approaches, Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TDDFT), perform well in cases with relatively weak electron correlation, such as the ground-state minima of closed-shell systems (Franck-Condon region). However, their applicability diminishes in more demanding scenarios.
