Time to improve health-related quality of life outcomes in patients with acute promyelocytic leukemia Major advances have been made in the treatment of patients with acute promyelocytic leukemia (APL) with the development of molecularly targeted therapies, first with the introduction of all-trans retinoic acid (ATRA) added to standard chemotherapy and more recently with the advent of arsenic tr...

We administered liposome-encapsulated all-trans retinoic acid (L-ATRA) to 48 patients with refractory hematologic malignancies using an every-other-day schedule for 28 days and doses of 15 to 175 mg/m2. In 19 patients, pharmacology studies were conducted after the first (day 1) and seventh (day 15) doses. In contrast to the decline in tretinoin concentration seen within 3 to 4 days of administr...

In September 1975, 5031 sea cucumbers (Holothuria atra Jager) were tagged with tetracycline and returned to a gutter on the seaward reef bench of Ananij Island, Enewetak Atoll, Marshall Islands. A sample of 184 individuals was collected in September 1976. Animals were dissected and plates of the calcareous ring were examined with ultraviolet radiation for tetracycline lines. Based on 18 tagged ...

Retinoids have been shown to modulate cell growth and differentiation in a variety of human tumor cell types, but their effects on B-cell non-Hodgkin's lymphomas (NHL-B) have not been explored. In this study, all-trans retinoic acid (ATRA) in the free form and liposome-encapsulated form (L-ATRA) were used to determine effects on fresh NHL-B patient cells as well as cell lines recently establish...
