Genome-wide CRISPR-based screen identifies E2F transcription factor 1 as a regulator and therapeutic target of aristolochic acid-induced nephrotoxicity.

Aristolochic Acid I (AAI) is widely present in traditional Chinese medicines derived from the Aristolochia genus and is known to cause significant damage to renal tubular epithelial cells. Genome-wide screening has proven to be a powerful tool in identifying critical genes associated with the toxicity of exogenous substances. To identify undiscovered key genes involved in AAI-induced renal toxicity, a genome-wide CRISPR library screen was conducted in the human kidney-2 (HK-2) cell line.

BiGM-lncLoc: Bi-level Multi-Graph Meta-Learning for Predicting Cell-Specific Long Noncoding RNAs Subcellular Localization.

The precise spatiotemporal expression of long noncoding RNAs (lncRNAs) plays a pivotal role in biological regulation, and aberrant expression of lncRNAs in different subcellular localizations has been intricately linked to the onset and progression of a variety of cancers. Computational methods provide effective means for predicting lncRNA subcellular localization, but current studies either ignore cell line and tissue specificity or the correlation and shared information among cell lines. In this study, we propose a novel approach, BiGM-lncLoc, treating the prediction of lncRNA subcellular localization across cell lines as a multi-graph meta-learning task.

Pharmacokinetics of cisplatin in the systemic versus hyperthermic intrathoracic or intraperitoneal chemotherapy.

Objective: To compare the pharmacokinetics and adverse effects of cisplatin administered via intravenous infusion for systemic chemotherapy (SC) versus injection into the perfusate during hyperthermic intrathoracic chemotherapy (HITHOC) or hyperthermic intraperitoneal chemotherapy (HIPEC).

Methods: Total 60 patients who received SC, HITHOC, or HIPEC in the Department of Oncology, Tangdu Hospital, were enrolled into this study. After administering same dose of cisplatin (40 mg) via either intravenous infusion (SC group) or injection into the perfusate during the HITHOC or HIPEC procedure, concentration of cisplatin in the plasma as well as in the hyperthermic perfusate at various time points was quantified by HPLC analysis.

Butyric acid alleviates LPS-induced intestinal mucosal barrier damage by inhibiting the RhoA/ROCK2/MLCK signaling pathway in Caco2 cells.

Butyric acid (BA) can potentially enhance the function of the intestinal barrier. However, the mechanisms by which BA protects the intestinal mucosal barrier remain to be elucidated. Given that the Ras homolog gene family, member A (RhoA)/Rho-associated kinase 2 (ROCK2)/Myosin light chain kinase (MLCK) signaling pathway is crucial for maintaining the permeability of the intestinal epithelium, we further investigated whether BA exerts a protective effect on epithelial barrier function by inhibiting this pathway in LPS-induced Caco2 cells.

Rapid and Visual Detection of Urinary Pathogens by Employing Bifunctional Deoxyribonucleic Acid Sensors and Aggregation of Gold Nanoparticles.

A simple, rapid, and visual approach is developed to perform diagnosis of urinary tract infection (UTI) and antimicrobial susceptibility testing (AST) by employing smart bifunctional DNA (bfDNA) sensors, exonuclease III, concatermers of CuO nanoparticles (CuONPs), and gold NPs (AuNPs) aggregation [AuNPs agglutination (AA)], namely, the bfDEC-AA method. The bfDNA sensors serve as probes for identifying 16S rRNA genes of bacterium or 18S rRNA of fungus and as mediators connecting the concatermers of CuONPs. The AA as a signal source is triggered by Cu(I)-catalyzed azide-alkyne cycloaddition click chemistry.

[Determination of 12 halogenated organic pollutants in edible fish by ultra performance liquid chromatography-high resolution mass spectrometry combined with ultrasound-assisted extraction and gel permeation chromatography purification].

Halogenated organic pollutants (HOPs) have attracted considerable attention owing to their persistence, bioaccumulation, and toxicity. The development of methods to detect HOPs in fish is challenging owing to the compositional complexity of fish matrices, which contain high levels of lipids and relatively low concentrations of HOPs. In addition, the lipophilicity of most HOPs renders their extraction difficult.

A distinct subgroup of AML resembling the APL immunophenotype is associated with DIC.

Background: The complexity of acute myeloid leukemia (AML) is increasingly recognized through the identification of distinct subgroups, including those with an APL-like immunophenotype characterized by the absence of CD34 and HLA-DR expression, which is widely recognized as a representative immunophenotype in acute promyelocytic leukemia (APL). This study sought to understand the clinical, molecular, and prognostic differences between AML patients with and without this phenotype.

Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

[Adverse Effects and Underlying Mechanisms of Soil Microplastics on Crops and Its Preventive Strategies].

Microplastics （MPs）, as a type of emerging environmental pollutant with a particle size < 5 mm, have been frequently detected in environmental matrices. MPs pollution in soils has been attracting the scientific community due to the increasing contaminant areas and continuous accumulation, leading to a high risk to crop production. In addition, recent studies have observed that long-term exposure to MPs could seriously harm the soil ecosystem because of their fine particle size and persistence in soils.

[Adsorption of Tetracycline in Composite-polluted Water by Biochar from Industrial Production].

Compared to the laboratory preparation of biochar, there is less research on the adsorption of antibiotics by industrial production of biochar in water. In this study, three types of industrial production biochar （peanut shell biochar, sludge biochar, and perishable waste biochar） were selected, and their adsorption performance for tetracycline in composite-polluted water was systematically studied. The results indicated that the Freundlich equation could well fit the adsorption isotherms of the three types of biochar for tetracycline.
