Invasive fungal infection (IFI) in patients with acute promyelocytic leukemia (APL) is a common phenomenon in developing countries. In a systematic study (Dual Inducing Differentiating agents-Indian Trial: DID-IT) using dual differentiating agents (ATO and ATRA) in 98 APL patients at our center we report 18.3% incidence of IFI (n-18). Among all cases of IFI three were definitive, 14 were probable and one was possible IFI. We conclude that incidence of IFI in APL is affected by environmental and therapy related factors and mere usage of dual differentiating agents need not necessarily decrease the incidence of fungal infections.

Background: Isotopologues resulting from the labelling of molecules with deuterium have attracted interest due to the isotope effect observed in chemistry and biosciences. Isotope effect may also play out in noncovalent interactions and mechanisms leading to intermolecular recognition. In chromatography, differences in retention time between isotopologues, as well as between isotopomers have been observed resulting in two different elution sequences (isotope effects): the normal isotope effect when heavier isotopologues retain longer than lighter analogues, and the inverse isotope effect featuring the opposite elution order.

The interaction between a cluster of differentiation 47 (CD47) on cancer cells and signal regulatory protein alpha (SIRPα) on macrophages is thought to hinder macrophage phagocytic activity, which can be blocked by combining siRNAs targeting SIRPα (siSIRPα) with simultaneous involvement of activating receptors like FcRs (Fc receptors) anti-programmed death-ligand 1 (anti-PD-L1). For this study, M1 macrophage-derived exosomes were used to deliver the siRNAs, isolated from lipopolysaccharide (LPS)-stimulated RAW264.7 cells and electroporated with siSIRPα.

Accurately detecting cysteine (Cys) in vivo is crucial for diagnosing Cys-related diseases. A novel ratiometric fluorescent probe featuring dual near-infrared emission is developed in this study for the in vivo ratio imaging of Cys. The probe comprises a hemicyanine organic small-molecule dye (HCy-CYS) with specific Cys recognition capabilities covalently coupled with carbon dots (CDs) synthesized using glutathione (GSH) as the carbon source (GCDs), forming a unique composite nanofluorescent probe (GCDs@CYS).

Activin A, a gonadal protein, not only stimulates the pituitary to secrete follicle-stimulating hormone (FSH) but also plays a crucial role in regulating various cell behaviors, such as cell proliferation, differentiation, apoptosis, migration, and invasion. Studies have shown an association between activin A expression and tumor progression, highlighting its dual role in cancer. Similar to transforming growth factor-beta (TGF-β), activin A can have both pro-tumor and anti-tumor effects, for instance, it inhibits the migration of lung adenocarcinoma cells, while promotes the migration of triple-negative breast cancer cells.

Accurate segmentation and classification of glomeruli are fundamental to histopathology slide analysis in renal pathology, which helps to characterize individual kidney disease. Accurate segmentation of glomeruli of different types faces two main challenges compared to traditional primitives segmentation in computational image analysis. Limited by small kernel size, traditional convolutional neural networks could hardly understand the complete context information of different glomeruli.
