A Microfluidic Approach for Assessing the Rheological Properties of Healthy Versus Thalassemic Red Blood Cells.

The deformability of red blood cells (RBCs) is critical for microvascular circulation and is impaired in hematological disorders such as thalassemia, a prevalent public health concern in Guangdong, China. While microfluidics enable high-precision deformability assessment, current studies lack standardization in deformation metrics and rarely investigate post-deformation recovery dynamics. This study introduces an automated microfluidic platform for systematically evaluating RBC deformability in healthy and thalassemic individuals.

Sumoylation-dependent control of Pmk1 phosphorylation during Magnaporthe oryzae infection.

Rice blast disease, caused by Magnaporthe oryzae, significantly threatens global rice yields.

Our research reveals that sumoylation of Pmk1 is vital for its infectious function.

Equivalent Self-Noise Suppression of Distributed Hydroacoustic Sensing System Using SDM Signals Based on Multi-Core Fiber.

To address the demand of equivalent self-noise suppression in a distributed hydroacoustic sensing system, this study proposes a method to enhance the acoustic sensitivity and signal-to-noise ratio (SNR) using space division multiplexed (SDM) technology based on multi-core fiber (MCF). Specifically, a dual-channel demodulation system for distributed acoustic sensing is designed using MCF. The responses of different cores in MCF are almost consistent under external acoustic pressure, while their self-noise is inconsistent.

Regulation of plant immunity through histone H3 β-hydroxybutyrylation-mediated transcriptional control.

Histone lysine β-hydroxybutyrylation (Kbhb) is a novel type of histone acylation whose prevalence and function remain unclear in plants. Here, we systematically characterized H3K9bhb in rice (Oryza sativa) and found that it is enriched at transcription start site (TSS) regions and serves as an active mark for gene expression. We demonstrated functional differences between H3K9bhb and the well-studied H3K9ac histone modification, particularly in regulating genes involved in the rice immune response.

Recurrence of Pleomorphic Adenoma in the Submandibular Gland: A Case Report and Literature Review.

Introduction: Recurrent pleomorphic adenoma (PA) in the submandibular gland is a rare tumor that may be misdiagnosed as an inflammatory lesion. The imaging manifestations of the submandibular gland recurrent PA are unclear, with only three case reports reporting CT and MRI imaging, respectively. Our report is the first case report that comprehensively describes the imaging manifestations of recurrent PA in the submandibular gland.

Histone H4K8hib modification promotes gene expression and regulates rice immunity.

This study uncovers the role of H4K8hib as an active epigenetic mark in rice that positively correlates with gene expression and enhances immune responses. Furthermore, HDA705 was identified as the key enzyme regulating H4K8hib. Mutation of HDA705 led to hyper-H4K8hib, which in turn activated the expression of defense-related genes and enhanced rice resistance to pathogens.

Regulatory Effect of PDGF/PDGFR on Hematopoiesis.

Platelet-derived growth factor (PDGF) is a critical cytokine with substantial regulatory effects on hematopoiesis. Recent research highlights the essential role of PDGF in the modulation of hematopoietic stem/progenitor cells (HSPCs), megakaryocytes/platelets, and thrombopoietin (TPO) synthesis within the bone marrow microenvironment. PDGF directly stimulates the proliferation and differentiation of HSPCs while also inhibiting apoptosis.

The treatment and outcome prediction analysis of pediatric acquired severe aplastic anemia.

Pediatric acquired severe aplastic anemia (SAA), a prevalent non-malignant hematological disorder, presents significant therapeutic challenges and carries considerable risks. Despite substantial progress in immunosuppressive therapy (IST) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) in recent years, the protracted treatment duration, substantial costs, and significant disparities in long-term survival outcomes among patients remain problematic. Identifying predictors of treatment response before therapy initiation is crucial for optimal clinical decision-making and complication prevention.

A secreted fungal laccase targets the receptor kinase OsSRF3 to inhibit OsBAK1-OsSRF3-mediated immunity in rice.

The identification effector targets and characterization of their functions are crucial for understanding pathogen infection mechanisms and components of plant immunity. Here, we identify the effector UgsL, a ustilaginoidin synthetase with a key role in regulating virulence of the rice false smut fungus Ustilaginoidea virens. Heterologous expression of UgsL in rice (Oryza sativa) enhances plant susceptibility to multiple pathogens, and host-induced gene silencing of UgsL enhances plant resistance to U.

HIF-2α inhibition disrupts leukemia stem cell metabolism and impairs vascular microenvironment to enhance chronic myeloid leukemia treatment.

Leukemic stem cells (LSCs) in chronic myeloid leukemia (CML) contribute to treatment resistance and disease recurrence. Metabolism regulates LSCs, but the mechanisms remain elusive. Here, we show that hypoxia-inducible factor 2α (HIF-2α) is highly expressed in LSCs in mouse and human CML and increases after tyrosine kinase inhibitor (TKI) treatment.

USP7 promotes IgA class switching through stabilizing RUNX3 for germline transcription activation.

Class switch recombination (CSR) diversifies the effector functions of antibodies and involves complex regulation of transcription and DNA damage repair. Here, we show that the deubiquitinase USP7 promotes CSR to immunoglobulin A (IgA) and suppresses unscheduled IgG switching in mature B cells independent of its role in DNA damage repair, but through modulating switch region germline transcription. USP7 depletion impairs Sα transcription, leading to abnormal activation of Sγ germline transcription and increased interaction with the CSR center via loop extrusion for unscheduled IgG switching.
