In many real-world applications of reinforcement learning (RL), performing actions requires consuming certain types resources that are non-replenishable in each episode. Typical include robotic control with limited energy and video games consumable items. tasks resources, we observe popular RL methods such as soft actor critic suffer from poor sample efficiency. The major reason is that, they t...
Bullous pemphigoid (BP) has a recognized association with solid organ tumors, but is relatively rare in hematological malignancies. We report a 67-year-old male who developed BP after being diagnosed with myelodysplastic syndrome and refractory anemia with excess of blast (RAEB). Skin biopsy elucidated sub-epidermal bulla using direct immunofluorescence, revealing linear C3 and IgG deposits alo...
We carried out bone marrow transplantation (BMT) in 50 patients with myelodysplastic syndrome (MDS) who were 55.3 to 66.2 years of age (median, 58.8 years). According to the criteria of the French-American-British (FAB) classification, 13 patients had refractory anemia (RA), 19 had RA with excess blasts (RAEB), 16 had RAEB in transformation or acute myelogenous leukemia (RAEB-T/AML), and 2 had ...
Bone marrow CD34(+) cell apoptosis (annexin V), proliferation (Ki-67), and Bcl-2-related protein expression was evaluated by flow cytometry in 102 patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia secondary to MDS (MDS-AML) and in 30 normal donors (NBM). Apoptosis was significantly increased in refractory anemia (RA)/RA with ringed sideroblasts (RARS) (56.9% [20.4%-93.6%])...
As anemia is frequently the main problem in myelodysplastic syndromes (MDS), we studied the efficacy of human erythropoietin (rhEpo) in stimulating the erythroid lineage in 14 patients, starting with 40 U/kg three times a week and doubling the dose every 6 weeks until a response was observed. The highest doses administered were 80 (n = 1), 160 (n = 4), 320 (n = 8) and 640 U/kg (n = 1). One pati...
Previous studies have shown that the cyclin-dependent kiterestingly, the p15 gene was frequently methylated in patients with high-risk MDS (refractory anemia with excess nase inhibitor (CDKI) genes p15 and p16 are frequently inactivated by genetic alterations in many malignant blasts [RAEB], RAEB in transformation [RAEB-t], and overt leukemia evolved from MDS; 14/18 [78%]) compared with tumors ...
Wilms tumor gene WT1 is expressed at high levels in hematopoietic malignancies, such as leukemias and myelodysplastic syndromes (MDS), and in various kinds of solid tumors, including lung cancer, and it exerts an oncogenic function in these malignancies. IgM and IgG WT1 antibodies were measured by means of dot blot assay in 73 patients with hematopoietic malignancies (16 acute myeloid leukemia ...
Because abnormal erythroid differentiation is the most common manifestation of the myelodysplastic syndromes (MDS), it was hypothesized that erythroid gene expression may be used to illustrate myelodysplastic transcription patterns. Ten normal bone marrow aspirates (NBM) were first analyzed using an erythroid-focused cDNA array to define steady-state transcription levels. Proliferation and diff...
