Identification of Anoikis-Related Genes in Chronic Kidney Disease Based on Bioinformatics Analysis Combined with Experimental Validation.

Background: Chronic kidney disease (CKD) is a progressive condition that arises from diverse etiological factors, resulting in structural alterations and functional impairment of the kidneys. We aimed to establish the Anoikis-related gene signature in CKD by bioinformatics analysis.

Methods: We retrieved 3 datasets from the Gene Expression Omnibus (GEO) database to obtain differentially expressed genes (DEGs), followed by Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, Gene Set Enrichment Analysis (GSEA) and Gene Set Variation Analysis (GSVA) of them, which were intersected with Anoikis-related genes (ARGs) to derive Anoikis-related differentially expressed genes (ARDEGs).

Development of two recombinase-aided amplification assays combined with lateral flow dipstick (RAA-LFD) and real-time fluorescence (RF-RAA) for the detection of Frog virus 3-like ranaviruses.

Frog virus 3-like ranaviruses (FV3-like viruses), particularly FV3 (Frog virus 3), represent typical species within the genus Ranavirus, primarily infecting amphibians and reptiles, thereby posing serious threats to aquaculture and biodiversity conservation. We designed a pair of universal primers and a probe targeting the conserved region of the major capsid protein (MCP) genes of FV3-like viruses. By integrating recombinase-aided amplification (RAA) with lateral flow dipstick (LFD) technology and real-time fluorescence (RF) modification, we established RAA-LFD and RF-RAA assays.

Mass production of ultrasmall MnO nanoparticles for glutathione responsive off-on / switching magnetic resonance imaging and tumor theranostics.

Individual theranostics with an integrated multifunction holds considerable promise for clinical application compared with multicomponent regimes. MnO nanoparticles with an ultrasmall size (4 nm) and mass production capability were developed with dual function of integrated tumor magnetic resonance imaging (MRI) and therapy. The high valence state of MnO nanocrystals enables a sensitive reaction with the glutathione (GSH) molecule and favorable decomposition ability, which further induces a unique, favorable, variable turn-off and turn-on MRI property.

An early lung cancer diagnosis model for non-smokers incorporating ct imaging analysis and circulating genetically abnormal cells (CACs).

Background: An increase in the prevalence of lung cancer that is not smoking-related has been noticed in recent years. Unfortunately, these patients are not included in low dose computer tomography (LDCT) screening programs and are not actually considered in early diagnosis. Therefore, improved early diagnosis methods are urgently needed for non-smokers.

Protective effect of ulinastatin against negative inflammatory response and organ dysfunction in acute aortic dissection surgery: The PANDA trial.

Ulinastatin is a protease-inhibiting drug with anti-inflammatory and other pharmacological properties. Little is known regarding its role following acute type A aortic dissection (ATAAD) surgery. We perform a randomized controlled trial to investigate the protective effect of ulinastatin against negative inflammatory response and organ dysfunction in ATAAD surgery (PANDA).

Association between red blood cell distribution width-to-albumin ratio and prognosis in post-cardiac arrest patients: data from the MIMIC-IV database.

Background: Cardiac arrest (CA) triggers a systemic inflammatory response, resulting in brain and cardiovascular dysfunction. The red blood cell distribution width (RDW)-to-albumin ratio (RAR) has been widely explored in various inflammation-related diseases. However, the predictive value of RAR for the prognosis of CA remains unclear.

Melatonin inhibits ferroptosis through the ATF3/GPX4 signaling pathway to relieve myocardial ischemia-reperfusion injury in rats.

Melatonin (MEL), functioning as a circulating hormone, is important for the regulation of ferroptosis in different health scenarios and acts as a crucial antioxidant in cardiovascular diseases. However, its specific function in ferroptosis related to myocardial ischemia-reperfusion injury (MIRI) remains to be fully elucidated. In our research, we utilized a rat model of MIRI induced by coronary artery ligation, along with a cell model subjected to hypoxia/reoxygenation (H/R).

Evaporation-Assisted Synthesis of Olympic Gels.

Catenated networks exclusively composed of intertwining rings were first envisioned as "Olympic gels" by Pierre-Gilles de Gennes four decades ago but have not been successfully prepared in artificial materials yet due to the challenge in synthesis. Herein, we present a bio-inspired, evaporation-assisted strategy to address this issue. In our design, the evaporation of liquid catalysts that induce ring-chain equilibrium of polymer systems drives macrocycles to encounter and assists their catenation through reversible cyclization.

Development of Off-On Near-Infrared Fluorescent Probes for Sensitive In Vivo Imaging of Amyloid-β Species with Enhanced Pharmacokinetic.

The fluorescent imaging of pathologically accumulated β-amyloid (Aβ) proteins is of significant importance to the diagnosis of Alzheimer's disease (AD). In the paper, we prepared two new NIR probes, NIR-1 and NIR-2, through hydrophilic modification of introducing water-soluble bioactive groups such as polyethylene glycol (PEG) and morpholine to tune in vivo pharmacokinetics for specific detection of soluble and insoluble Aβ species. The in vitro assessments confirm that both NIR-1 and NIR-2 display strong near-infrared (NIR) fluorescence (FL) enhancement upon association with Aβ42 monomers, oligomers or aggregates (λem > 670 nm) and show high sensitive, rapid and selective response towards Aβ42 species.

Rapid identification of pathogenic bacteria from clinical positive blood cultures virus-like magnetic bead enrichment and MALDI-TOF MS profiling.

Reducing the time required for the detection of bacteria in blood samples is a critical area of investigation in the field of clinical diagnosis. Positive blood culture samples often require a plate culture stage due to the interference of blood cells and proteins, which can result in significant delays before the isolation of single colonies suitable for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis. In this study, we developed a non-specific enrichment strategy based on SiO-encapsulated FeO nanoparticles combined with MALDI-TOF MS for direct identification of bacteria from aqueous environments or positive blood culture samples.

Monoclonal antibodies (mAbs) and mAb-derived biologics have achieved substantial success across various therapeutic areas over recent decades. Their widespread adoption, however, remains constrained due to high prices and challenges in supply. Here, we examine the general price and cost structure of mAbs and mAb-derived therapeutics and identify directions to improve affordability and strategies to ensure supply.

Ticagrelor, an effective antiplatelet for acute coronary syndrome (ACS), may elevate serum uric acid (SUA), potentially causing gout. This study aims to identify risk factors for ticagrelor-induced in-hospital gout in patients with ACS and create a predictive model for clinical use.A total of 1164 patients with ACS treated with ticagrelor (n = 640) or clopidogrel (n = 524) were retrospectively analyzed.

G-protein coupled receptor GPR124 protects against podocyte senescence and injury in diabetic kidney disease.

Although emerging studies highlight the pivotal role of podocyte senescence in the pathogenesis of diabetic kidney disease (DKD) and aging-related kidney diseases, therapeutic strategies for preventing podocyte senescence are still lacking. Here, we identified a previously unrecognized role of GPR124, a novel adhesion G protein-coupled receptor, in maintaining podocyte structure and function by regulation of cellular senescence in DKD. Podocyte GPR124 was significantly reduced in db/db diabetic (a type 2 diabetic mouse model) and streptozocin-induced diabetic mice (a type 1 diabetic model), which was further confirmed in kidney biopsies from patients with DKD.
