Article Synopsis
  • The study investigates the effectiveness of a specific imaging technology, ASiR-V, in reducing radiation doses during chest CT scans for children living in a high-altitude area.
  • Children undergoing chest CT at different tube voltages (100 kV vs. 80 kV) and ASiR-V settings were compared to assess image quality and radiation exposure.
  • Results indicated that using ASiR-V with a lower tube voltage significantly decreased radiation doses while maintaining acceptable image quality for pediatric patients.

In the global context of development transformation, digital transformation (DT) has emerged as a prevalent practice among international corporations, facilitating the simultaneous enhancement of economic growth. However, limited research on how digital transformation affects green production, especially at a micro level, poses risks by impeding the understanding of strategies for balancing economic growth and environmental sustainability. This study addresses a critical research gap by elucidating the influence of digitization on green total factor productivity (GTFP).

Nuclear localization of the metabolic enzyme PKM2 is widely observed in various cancer types. We identify nuclear PKM2 as a non-canonical RNA-binding protein (RBP) that specifically interacts with folded RNA G-quadruplex (rG4) structures in precursor mRNAs (pre-mRNAs). PKM2 occupancy at rG4s prevents the binding of repressive RBPs, such as HNRNPF, and promotes the expression of rG4-containing pre-mRNAs (the "rG4ome").

Objectives: Recent studies have indicated that radiomics may have excellent performance and clinical application prospects in the differential diagnosis of benign and malignant vertebral compression fractures (VCFs). However, multimodal magnetic resonance imaging (MRI)-based radiomics model is rarely used in the differential diagnosis of benign and malignant VCFs, and is limited to lumbar. Herein, this study intends to develop and validate MRI radiomics models for differential diagnoses of benign and malignant VCFs in patients.

Since the 20th century, Red Culture has served as a significant informal institution guiding revolutionary trajectory and developmental course. However, integrating Red Culture into contemporary corporate management and leveraging its constructive influence within today's market-driven economy necessitates comprehensive exploration and thoughtful consideration. This study aims to explore the potential influence of Red Culture on contemporary innovation.

Proteomic methods for RNA interactome capture (RIC) rely principally on crosslinking native or labeled cellular RNA to enrich and investigate RNA-binding protein (RBP) composition and function in cells. The ability to measure RBP activity at individual binding sites by RIC, however, has been more challenging due to the heterogenous nature of peptide adducts derived from the RNA-protein crosslinked site. Here, we present an orthogonal strategy that utilizes clickable electrophilic purines to directly quantify protein-RNA interactions on proteins through photoaffinity competition with 4-thiouridine (4SU)-labeled RNA in cells.

Article Synopsis
  • HNRNPK is a protein that plays a crucial role in processing pre-mRNA and localizes to the nucleus but can move to the cytoplasm, influencing cancer growth and spread.
  • The study found that Keratin 19 (K19) binds to HNRNPK, keeping it in the cytoplasm, while lacking K19 leads to HNRNPK being unable to localize there, which decreases cell proliferation in breast cancer cells.
  • HNRNPK's presence in the cytoplasm enhances the stability of certain cancer-related mRNAs, particularly affecting pathways like p53 signaling, indicating the importance of K19 in regulating HNRNPK and its function in cancer progression.

The TBX20 gene plays a crucial role in embryonic development and has been involved in various diseases, such as heart defects, intellectual disability, and cancer. Herein, we have established a TBX20-knockout human embryonic stem cell line (WAe009-A-84) that maintains stem cell-like features, pluripotency, a normal karyotype, and the ability to differentiate into all three germ layers in vivo. This cell line will be a valuable resource for exploring TBX20's role in human development and could have significant implications for regenerative medicine and disease modeling.

Hyperlactatemia often occurs in critically ill patients during severe sepsis/septic shock and is a powerful predictor of mortality. Lactate is the end product of glycolysis. While hypoxia due to inadequate oxygen delivery may result in anaerobic glycolysis, sepsis also enhances glycolysis under hyperdynamic circulation with adequate oxygen delivery.

Coronary microembolization (CME) is an intractable complication results from acute coronary syndrome. CME-induced myocardial apoptosis was associated with progressive cardiac contractile dysfunction. miR-29b-3p has been reported implicated in variety cardiovascular diseases, but its function in CME-induced myocardial injury is yet unknown.

Acute myocardial infarction (AMI) is one of the most serious cardiovascular diseases with high morbidity and mortality. Numerous studies have indicated that S100A12 may has an essential role in the occurrence and development of AMI, and in-depth studies are currently lacking. The purpose of this study is to investigate the effect of S100A12 on inflammation and oxidative stress and to determine its clinical applicability in AMI.

Mitogen-activated protein kinase phosphatase 1 (Mkp-1) KO mice produce elevated cytokines and exhibit increased mortality and bacterial burden following systemic Escherichia coli infection. To understand how Mkp-1 affects immune defense, we analyzed the RNA-Seq datasets previously generated from control and E. coli-infected Mkp-1 and Mkp-1 mice.

The TFIID component, TAF7, has been extensively characterized as essential for transcription and is critical for cell proliferation and differentiation. Here, we report that TAF7 is a previously unknown RNA chaperone that contributes to the regulation of protein synthesis. Mechanistically, TAF7 binds RNAs in the nucleus and delivers them to cytoplasmic polysomes.

Repressor element 1-silencing transcription factor (REST) plays a crucial role in the differentiation of neural progenitor cells (NPCs). C-terminal domain small phosphatases (CTDSPs) are REST effector proteins that reduce RNA polymerase II activity on genes required for neurogenesis. miR-26b regulates neurogenesis in zebrafish by targeting ctdsp2 mRNA, but the molecular events triggered by this microRNA (miR) remain unknown.

We have previously shown that -deficient mice produce elevated TNF-α, IL-6, and IL-10 following systemic infection, and they exhibited increased mortality, elevated bacterial burden, and profound metabolic alterations. To understand the function of Mkp-1 during bacterial infection, we performed RNA-sequencing analysis to compare the global gene expression between -infected wild-type and mice. A large number of IFN-stimulated genes were more robustly expressed in -infected mice than in wild-type mice.
