JMML is an aggressive hematopoietic malignancy of early childhood, and allogeneic HSCT is the only curative treatment for this disease. Umbilical cord blood is one of donor sources for HSCT in JMML patients who do not have an HLA-compatible relative, but engraftment failure remains a major problem. Here, we report two cases of JMML who were successfully rescued by HSCT from an HLA-mismatched parent after development of primary engraftment failure following unrelated CBT. Both patients had severe splenomegaly and underwent unrelated CBT from an HLA-mismatched donor...

We report a facile and new method to tune the electron transport (ETp) band gaps of proteins (bovine serum albumin, BSA) via doping with other molecules (cyanocobalamin, Vb12). The results indicated that doping with Vb12 can enhance the ETp ability of BSA and reduce its conduction band (CB) and valence band (VB) energy levels, thereby achieving the goal of tuning protein ETp band gaps.

Background/Aims: Cytotoxicity induced by reactive oxygen species (ROS) is critical for the effectiveness of chemotherapeutic drugs used in the treatment of acute myeloid leukemia (AML). This study aimed to investigate whether ROS contributes to cytotoxicity in AML cells when treated with homoharringtonine (HHT) and etoposide (ETP) in combination. Methods: AML cell lines THP1 and HL60 and primary AML cells from patients were treated with HHT and ETP alone or in combination, and cell viability was determined by trypan blue exclusion test, and apoptosis was analyzed by annexin-V/propidium iodide double staining as well as Western blot for measuring expression of cleaved caspase-9 and cleaved caspase-3...

BACKGROUND: Clinical studies have shown that all-trans retinoic acid (RA), which is often used in treatment of cancer patients, improves hemostatic parameters and bleeding complications such as disseminated intravascular coagulation (DIC). However, the mechanisms underlying this improvement have yet to be elucidated. In vitro studies have reported that RA upregulates thrombomodulin (TM) expression on the endothelial cell surface. The objective of this study was to investigate how and to what extent the TM concentration changes after RA treatment in cancer patients, and how this variation influences the blood coagulation cascade...

BACKGROUND/OBJECTIVES: We compared the ex vivo haemostatic capacity of RTFP24 with FFP upon thawing and >24 h post-thaw. We included thrombin generation (TG) as few studies had compared global haemostatic function, and most did not directly compare RTFP24 with FFP >24 h post-thaw. MATERIALS/METHODS: Twenty units each of RTFP24 and FFP were measured for coagulation factors and thrombin generation upon thawing (D0) and 4 days post-thaw (D4). Labile factors were also measured from D1 to D3...

Factor V Leiden (FVL) mutation is the most common genetic risk factor for venous thromboembolism. In families with a history of thrombosis, FVL can be present in 18%. Thrombin generation test is commonly used as an evaluation tool of thrombotic risk. The objective of this study was to evaluate the thrombogenic potential of FVL in asymptomatic carriers and in patients with personal or familial history of thrombosis. This was a retrospective single center study including 160 patients. Among them, 43 had personal history of thrombosis and 117 had familial history of thrombosis...

Obesity is a risk factor for cardiovascular diseases. The latter being dependent (at least in part) on plasma procoagulant imbalance (i.e., hypercoagulability). Information on hypercoagulability associated with obesity is scanty and mainly based on global traditional coagulation tests or on the measurement of individual components of coagulation (i.e., pro- and anticoagulants). Plasma from 33 obese subjects was investigated soon before endoscopic balloon placement and after removal (6 months later) by thrombin-generation procedures that are thought to represent much better than any other in vitro test the coagulation process occurring in vivo...

OBJECTIVES: The present study developed Nitro-Carba Test (NCT), a rapid and simple chromogenic method for screening of Carbapenemase-producing Enterobacteriaceae (CPE). METHODS: The NCT was validated with a total of 31 carbapenemase-producing isolates (9 KPCs, 11 MBLs and 11 OXA-48s) and with 56 non-carbapenemase-producing strains. The assay relies on the hydrolysis of nitrocefin in the presence of carbapenems. The carbapenemases were extracted with lysis buffer prior to addition to wells with and without imipenem (IPM), meropenem (MEM) and ertapenem (ETP)...

Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is an aggressive hematological malignancy for which optimal therapeutic approaches are poorly characterized. Using computational biology modeling (CBM) in conjunction with genomic data from cell lines and individual patients, we generated disease-specific protein network maps that were used to identify unique characteristics associated with the mutational profiles of ETP-ALL compared to non-ETP-ALL (T-ALL) cases and simulated cellular responses to a digital library of FDA-approved and investigational agents...

Treatability of anaerobically digested distillery wastewater is challenging because of its high pollution load of COD up to 40,000 ppm. This research investigates the possibilities of retrofitting the effluent treatment plant (ETP) of a distillery with microalgae treatment step. For this, at first the photobioreactors of capacity 50 L and 500 L were customized for the cultivation of Spirulina sp. under xenon lamp and sunlight. The reactor supported the maximum specific growth rate up to 0.42 ± 0...

Given that FLT3 expression is highly restricted on lymphoid progenitors, it is possible that the established role of FLT3 in the regulation of B and T lymphopoiesis reflects its high expression and role in regulation of lymphoid-primed multipotent progenitors (LMPPs) or common lymphoid progenitors (CLPs). We generated a Flt3 conditional knock-out (Flt3fl/fl ) mouse model to address the direct role of FLT3 in regulation of lymphoid-restricted progenitors, subsequent to turning on Rag1 expression, as well as potentially ontogeny-specific roles in B and T lymphopoiesis...

RATIONALE: Early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is a small subtype of T-cell acute lymphoblastic leukemia with a typical immune-phenotype: lack of T-lineage cell surface markers CD1a and CD8 expression, weak or absent CD5 expression, at least one of the myeloid or hematopoietic stem cell markers. It is characterized by high rate of induction failure and the effective unified treatment strategies are still indeterminate. We present 2 ETP-ALL cases. PATIENT CONCERNS: A 42-year-old man presented with abnormal hemogram for 4 months, intermittent fever for 2 months and cough for 1 week...
