Low-dose melphalan in elderly patients with relapsed or refractory acute myeloid leukemia: A well-tolerated and effective treatment after hypomethylating-agent failure.

Relapsed or refractory (R/R) disease remains challenging in acute myeloid leukemia (AML), especially in elderly patients not considered eligible for intensive treatment options. We retrospectively evaluated the safety and efficacy of low-dose melphalan (LD-Mel) in a multicenter analysis in patients over 65 years with R/R AML, who previously had received ≥1 non-curative treatment line. The study included 31 patients (median age 77 years) with 1-4 previous treatment lines.

Qualitative and Quantitative Analysis of Primary Neocortical Areas in Selected Mammals.

The present study focuses on the relationship between neocortical structures and functional aspects in three selected mammalian species. Our aim was to compare cortical layering and neuron density in the projection areas (somatomotor, M1; somatosensory, S1; auditory, A1; and visual, V1; each in a wider sense). Morphological and design-based stereological analysis was performed in the wild boar (Sus scrofa scrofa) as a representative terrestrial hoofed animal (artiodactyl) and the common dolphin (Delphinus delphis) as a highly derived related aquatic mammal (cetartiodactyl).

Prevalence and Genetics of Leber Hereditary Optic Neuropathy in the Danish Population.
