AMLnet, A deep-learning pipeline for the differential diagnosis of acute myeloid leukemia from bone marrow smears.

Acute myeloid leukemia (AML) is a deadly hematological malignancy. Cellular morphology detection of bone marrow smears based on the French-American-British (FAB) classification system remains an essential criterion in the diagnosis of hematological malignancies. However, the diagnosis and discrimination of distinct FAB subtypes of AML obtained from bone marrow smear images are tedious and time-consuming.

A global study for acute myeloid leukemia with RARG rearrangement.

Acute myeloid leukemia (AML) with retinoic acid receptor γ (RARG) rearrangement has clinical, morphologic, and immunophenotypic features similar to classic acute promyelocytic leukemia. However, AML with RARG rearrangement is insensitive to alltrans retinoic acid (ATRA) and arsenic trioxide (ATO) and carries a poor prognosis. We initiated a global cooperative study to define the clinicopathological features, genomic and transcriptomic landscape, and outcomes of AML with RARG rearrangements collected from 29 study groups/institutions worldwide.

Case Report: The First Report of Fusion Gene in Acute Myeloid Leukemia Patient Detected by Next-Generation Sequencing.

The fusion gene is a constitutively active tyrosine kinase that can be detected in 6% of T-cell acute lymphoblastic leukemia (T-ALL) patients, and it can also be found in B-cell acute lymphoblastic leukaemia (B-ALL). However the fusion in acute myeloid leukemia (AML) has not yet been reported. Up to now, the sensitivity of -positive patients to tyrosine kinase inhibitor (TKI) is still controversial.

Minimal residual disease level determined by flow cytometry provides reliable risk stratification in adults with T-cell acute lymphoblastic leukaemia.

Minimal residual disease (MRD) is an important independent prognostic factor for relapse and survival in acute lymphoblastic leukaemia (ALL). Compared with adult B-cell ALL, reports of adult T-cell ALL (T-ALL) MRD have been scarce and mostly based on molecular methods. We evaluated the prognostic value of multiparameter flow cytometry (FCM)-based MRD at the end of induction (EOI-MRD).

The enhancing antifungal effect of AD1 aptamer-functionalized amphotericin B-loaded PLGA-PEG nanoparticles with a low-frequency and low-intensity ultrasound exposure on C.albicans biofilm through targeted effect.

The prevalence and fatality rates with fungal biofilm-associated infections urgently need to develop targeted therapeutic approaches to augment the action of antifungal drugs. This study developed amphotericin B-loaded PLGA-PEG nanoparticles (AmB-NPs) with AD1 aptamer conjugation on its surface via an EDC/NHS technique. Their high nuclease resistance of the conjugation was confirmed by PAGE gel electrophoresis.

Intracerebral Hemorrhage as the Initial Presentation of Chronic Myeloid Leukemia: A Case Report and Review of the Literature.

Intracerebral hemorrhage (ICH) is an unusual complication in chronic myeloid leukemia (CML). Intracranial involvement, causing ICH as an initial presentation is extremely rare in CML. Herein, we reported the first case of a newly diagnosed CML patient, who presented with headaches accompanied by nausea and vomiting as the initial presentations, caused by ICH.

Comparison of Early T-Cell Precursor and Non-ETP Subtypes Among 122 Chinese Adults With Acute Lymphoblastic Leukemia.

Adult T-cell acute lymphoblastic leukemia (T-ALL) is a rare hematological malignancy and significantly linked to poor outcomes. Early T-cell precursor (ETP) leukemia is a unique subtype of T-ALL. The aim of this study is to compare the differences between ETP and non-ETP ALLs in China.

A synergistic bactericidal effect of low-frequency and low-intensity ultrasound combined with levofloxacin-loaded PLGA nanoparticles on M. smegmatis in macrophages.
