The pterocarpanquinone LQB‑118 compound induces apoptosis of cytarabine‑resistant acute myeloid leukemia cells.

Acute myeloid leukemia (AML) is a complex hematological disorder characterized by blockage of differentiation and high proliferation rates of myeloid progenitors. Anthracycline and cytarabine‑based therapy has remained the standard treatment for AML over the last four decades. Although this treatment strategy has increased survival rates, patients often develop resistance to these drugs.

Analysis of Benzene Exposure in Gas Station Workers Using Trans,Trans-Muconic Acid.

In Brazil, gas station workers are occupationally exposed to the benzene present in gasoline. Brazilian law indicates the use of trans,trans-muconic acid(t,t-MA) as a biomarker of benzene exposure. The aim of this study was to evaluate the level of exposure to benzene in gas station workers, through the quantification of t,t-MA present in urine.

Characterization of a human induced Pluripotent Stem (iPS) cell line (INCABRi002-A) derived from a primary myelofibrosis patient harboring the 5-bp insertion in CALR and the p.W146X mutation in TP53.

Primary myelofibrosis (PMF) is a hematological malignancy characterized by activation of the JAK/STAT pathway and risk of leukemic transformation. In this study, we generated an induced Pluripotent Stem (iPS) cell line derived from a 65-year old male PMF patient carrying the 5-pb insertion in the CALR gene (CALR) and the c.437 G > A mutation in the TP53 gene (p.

An uncommon t(9;11)(p24;q22) with monoallelic loss of and genes in a child with myelodysplastic syndrome/acute myeloid leukemia who evolved from Fanconi anemia.

Background: Myelodysplastic syndrome (MDS) is rare in the pediatric age group and it may be associated with inheritable bone marrow failure (BMF) such as Fanconi anemia (FA). FA is a rare multi-system genetic disorder, characterized by congenital malformations and progressive BMF. Patients with FA usually present chromosomal aberrations when evolving to MDS or acute myeloid leukemia (AML).

Generation and characterization of a human induced pluripotent stem (iPS) cell line derived from an acute myeloid leukemia patient evolving from primary myelofibrosis carrying the CALR 52bp deletion and the ASXL1 p.R693X mutation.

Peripheral blood sample was donated by a 61years old female patient diagnosed with acute myeloid leukemia secondary to a primary myelofibrosis harboring the 52-bp deletion in the CALR gene (c.1092_1143del, p.L367fs*46) and the R693X mutation in the ASXL1 gene (c.

Presence of new mutations in the TP53 gene in patients with low-risk myelodysplastic syndrome: two case reports.

Background: Myelodysplastic syndromes are heterogeneous disorders. Patients with myelodysplastic syndrome disease often have ineffective hematopoiesis, cytopenias, blood cell dysplasia in one or more cell types, and are at high risk for developing acute myeloid leukemia. In myelodysplastic syndrome, mutations of TP53 gene are usually associated with complex karyotype and confer a worse prognosis.

The surgery of the long-term central venous accesses in oncology.

The implantation of Long-Term Central Venous Catheters (LTCVC) in cancer patients has been essential to conduct the oncological treatments of today. The complexity of the protocols requires accuracy on the management of such devices in order to keep them long-functioning. The article focuses on such subject from an oncological perspective, pointing out threats of the disease to the central venous system (CVS) and the ways to face them successfully.
