Characteristics and literature review of ETV6::ABL1 fusion gene-positive acute myeloid leukemia.

Objective: To describe the features of ETV6::ABL1 AML as well as the clinical treatment and outcomes.

Methods: Clinical data were collected from three patients diagnosed with ETV6::ABL1 AML at Hebei Yanda Lu Daopei Hospital and Beijing Lu Daopei Hospital. Their clinical and laboratory features were analyzed, and the treatment process and outcomes were described.

Ultrasensitive levofloxacin electrochemical biosensor based on semiconducting covalent organic framework/poly-L-cysteine/triangular Ag nanoplates modified glassy carbon electrode.

A novel electrochemical biosensor with excellent performance was fabricated for levofloxacin (LEV) detection, which adopted triangular Ag nanoplates (Tri-AgNP) confined in a poly-L-cysteine (poly-L-Cys) film and a semiconducting covalent organic framework (COF) as the electrochemical sensing material. The developed electrochemical sensor revealed excellent analytical properties because of its good electrical conductivity, fast electron transfer, and abundant bioactive site. Based on this, a linear relationship between the LEV concentration and the peak current response at 0.

The Efficacy and Safety of Plasma Exchange in the Treatment of Thrombotic Thrombocytopenic Purpura.

Background: Thrombotic thrombocytopenic purpura (TTP) is a clinically rare thrombotic cardiovascular and microvascular disease. The purpose of this study was to observe the clinical efficacy and safety of plasma exchange in the treatment of TTP.

Methods: A total of 16 TTP patients who underwent plasma exchange from January 2015 to December 2020 were selected.

A ratiometric sensor for selective detection of Hg ions by combining second-order scattering and fluorescence signals of MIL-68(In)-NH.

Ratio fluorescence has attracted much attention because of its self-calibration properties. However, it is difficult to obtain suitable fluorescent materials with well-resolved signals simultaneously under one excitation. In this work, we report a different strategy, using MIL-68(In)-NH as both the fluorescence element and the scattered light unit, and coupling the fluorescence and the scattered light to construct the fluorescence and scattered light ratio system.
