Pharmacodynamic material basis of licorice and mechanisms of modulating bile acid metabolism and gut microbiota in cisplatin-induced liver injury based on LC-MS and network pharmacology analysis.

Ethnopharmacological Relevance: Cisplatin (CP), a widely used antineoplastic agent, is a leading cause of drug-induced liver injury (DILI) due to its hepatotoxic effects. Licorice (GC), an established remedy in traditional Chinese medicine (TCM), has shown promise in addressing liver diseases and DILI. Nonetheless, the specific active components and underlying mechanisms of GC in mitigating CP-induced liver injury remain inadequately investigated.

Lightweight Knowledge Distillation-Based Transfer Learning Framework for Rolling Bearing Fault Diagnosis.

Compared to fault diagnosis across operating conditions, the differences in data distribution between devices are more pronounced and better aligned with practical application needs. However, current research on transfer learning inadequately addresses fault diagnosis issues across devices. To better balance the relationship between computational resources and diagnostic accuracy, a knowledge distillation-based lightweight transfer learning framework for rolling bearing diagnosis is proposed in this study.

Extracorporeal Shock Wave Therapy Improves Nontraumatic Knee Contracture in a Rat Model.

Background: Joint contractures occur frequently after trauma or immobilization, but few reliable treatments are available. Extracorporeal shock wave therapy (ESWT) is often used for various musculoskeletal conditions, but whether it is effective for treating joint contractures and the mechanisms through which it might work for that condition remain unclear.

Questions/purposes: Using a rat model, we asked, does ESWT (1) inhibit the progression of knee contracture, (2) ameliorate histopathologic joint changes, and (3) improve serum and myofascial fibrosis-related factors? We also asked, (4) what is the possible mechanism by which ESWT inhibits knee contracture?

Methods: Thirty-two male Sprague-Dawley rats (12 weeks old and weighing 300 to 400 g) were randomly separated into two groups: control group (eight rats) and noncontrol group (24) in the first week.

Prophylactic Use of Antibiotics for Postsurgical Infection in c-TACE and DEB-TACE High-Risk Patients: A Case-Control Study.

Objectives: According to recent reports, prophylactic use of antibiotics is not always required in conventional transarterial chemoembolization (c-TACE). However, clinical evidence of prophylactic antibiotics in drug-eluting beads transarterial chemoembolization (DEB-TACE) to prevent postsurgical infection is limited. This study is aimed to evaluate the correlation between the preoperative prophylactic application of antibiotics and postoperative infection in c-TACE or DEB-TACE, especially in a population with a high risk for postsurgical infection.

Suppressor of cytokine signaling 1 (SOCS1) inhibits antiviral responses to facilitate Senecavirus A infection by regulating the NF-κB signaling pathway.

Senecavirus A (SVA) is a new virus inducing porcine idiopathic vesicular disease that causes significant economic losses. Although some progress has been made in etiological research, the role of host factors in SVA infection remains unclear. This study investigated the role of the host factor, suppressor of cytokine signaling 1 (SOCS1), in SVA infection.

Negative Regulators of Inflammation Response to the Dynamic Expression of Cytokines in DF-1 and MDCK Cells Infected by Avian Influenza Viruses.

The H5N1 and H9N2 avian influenza viruses (AIVs) seriously endanger the poultry industry and threaten human health. Characteristic inflammatory responses caused by H5N1 and H9N2 AIVs in birds and mammals result in unique clinical manifestations.

Synthesis and evaluation of anticancer activity of BOC26P, an ortho-aryl chalcone sodium phosphate as water-soluble prodrugs in vitro and in vivo.

Major limitations of chalcones as clinical anticancer agents are water insolubility and poor bioavailability, which may be improved by a classic phosphate prodrug strategy that targets non-specific alkaline phosphatase (ALP) for releasing the parent drug in vivo. In this study, we found that BOC26P, a phosphate prodrug of chalcone OC26, exhibits excellent water solubility and improved plasma concentration in vivo by either i.v.

SOX10 induced Nestin expression regulates cancer stem cell properties of TNBC cells.

The mechanisms modulating the cancer stem cell (CSC) properties of triple negative breast cancer (TNBC) cells were not fully understood. In this study, we performed data mining in Breast Cancer Gene-Expression Miner v4.0 and found that TNBC tumors had significantly higher NES mRNA expression than other breast cancer subtypes.

Downregulation of AATK mediates microRNA-558-induced resistance of A549 cells to radiotherapy.

The deregulation of microRNAs (miRNAs) is often implicated in the control of sensitivity to radiotherapy. The objective of the present study was to identify the association between miR‑558 and apoptosis‑associated tyrosine kinase (AATK), and their importance in regulating the development of resistance to radiotherapy. The current study demonstrated that AATK, a radiosensitization-associated gene, is a target of miR‑558 in lung cancer cells, using in silico analysis and a luciferase reporter system.

Serum miR-152, miR-148a, miR-148b, and miR-21 as novel biomarkers in non-small cell lung cancer screening.

Lung cancer, predominantly by non-small cell lung cancer (NSCLC), is the leading cause of cancer-related deaths over the world. Late diagnosis is one of important reasons for high mortality rate in lung cancer. Current diagnostic approaches have disadvantages such as low accuracy, high cost, invasive procedure, etc.

Synthesis, antioxidant, and antimicrobial evaluation of some 2-arylbenzimidazole derivatives.

A series of 2-arylbenzimidazole derivatives (3a-3p and 4a-4i) were synthesized and evaluated as potential antioxidant and antimicrobial agents. Their antioxidant properties were evaluated by various in vitro assays including hydroxyl radical (HO) scavenging, superoxide radical anion (O2(-)) scavenging, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, and ferric reducing antioxidant power. Results demonstrated that compounds with hydroxyl group at the 5-position of benzimidazole ring had a comparable or better antioxidant activity in comparison to standard antioxidant tert-butylhydroquinone (TBHQ).

Deubiquitinase inhibition of 19S regulatory particles by 4-arylidene curcumin analog AC17 causes NF-κB inhibition and p53 reactivation in human lung cancer cells.

Proteasome inhibitors have been suggested as potential anticancer agents in many clinical trials. Recent evidence indicates that proteasomal deubiquitinase (DUB) inhibitors, bearing a different mechanism from that of traditional proteasome inhibitors, would be appropriate candidates for new anticancer drug development. In the present study, we describe the deubiquitinase inhibition of 19S regulatory particles (19S RP) by AC17, a 4-arylidene curcumin analog synthesized in our laboratory.

2a, a novel curcumin analog, sensitizes cisplatin-resistant A549 cells to cisplatin by inhibiting thioredoxin reductase concomitant oxidative stress damage.

(1E,4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(5-methylfuran-2-yl)hepta-1,4,6-trien-3-one (2a), a novel curcumin analog, was previously synthesized in our laboratory as a potential thioredoxin reductase (TrxR) inhibitor with excellent growth inhibitory effects on several TrxR over-expressed cancer cells. In this study, our further studies show that 2a is able to inhibit the growth of cisplatin-resistant A549 (A549/CDDP) cells much more effectively in a dose-dependent manner than that of A549 cells in antiproliferative activity experiments. Moreover, 2a-pretreated A549/CDDP cells are sensitive to cisplatin treatment, which is accompanied by the inhibition of TrxR activity in A549/CDDP cells.

In the present study, we prepared forty-five isocoumarin phosphorus analogues (i.e.

An efficient route to 4-halophosphaisocoumarins via CuX2-mediated direct halocyclization of 2-(1-alkynyl)phenylphosphonic acid diesters.

A series of 4-halophosphaisocoumarins were synthesized via CuX2 (X = Br, Cl) -mediated direct halocyclization of 2-(1-alkynyl)phenylphosphonic acid diesters in dichloroethane with the addition of n-Bu4NX or/and AgI in good to excellent yields. This reaction provides an efficient route to 4-halophosphaisocoumarins and represents the first example of bromo- and chlorocyclization of unsaturated phosphonic acid diesters.

Application of siRNA against SARS in the rhesus macaque model.

Containment of the SARS coronavirus (SCV) outbreak was accompanied by the rapid characterization of this new pathogen's genome sequence in 2003, encouraging the development of anti-SCV therapeutics using short interfering RNA (siRNA) inhibitors. A pair of siRNA duplexes identified as potent SCV inhibitors in vitro was evaluated for in vivo efficacy and safety in a rhesus macaque SARS model using intranasal administration with clinical viable delivery carrier in three dosing regimens. Observations of SCV-induced SARS-like symptoms, measurements of SCV RNA presence in the respiratory tract, microscopic inspections of lung histopathology, and immunohistochemistry sections from 21 tested macaques consistently demonstrated siRNA-mediated anti-SCV activity.

Chloroplast-like organelles were found in enucleate sieve elements of transgenic plants overexpressing a proteinase inhibitor.

SaPIN2a, a plant proteinase inhibitor from nightshade (Solanum americanum), was located to the enucleate sieve elements (SEs) of phloem. The expressed SaPIN2a in transgenic lettuce showed inhibition of plant endogenous trypsin- and chymotrypsin-like activities, suggesting that SaPIN2a can regulate proteolysis in plant cells. To further investigate the physiological role of SaPIN2a, we produced transgenic nightshade and lettuce plants overexpressing SaPIN2a from the cauliflower mosaic virus (CaMV) 35S promoter using Agrobacterium-mediated transformation.
