In addition, screening cytotoxicity trials were conducted on the human intestinal cell line Caco-2 with C18-mica-4 (0-125 µg/ml).

Only one of the endpoints evaluated (the reduction of tetrazolium MTS salt by dehydrogenase enzymes) showed a significant decrease in cellular viability after 48h at the highest concentration tested. C18-mica-4 shows structural resistance to both, gastric and gastrointestinal, digestion.

A successful development of a functionalized mica has been made with a promising potential application as a carrier to the drug.

This study aimed to examine the effects of apigenin (API) on the proliferation, migration, and invasion of human tongue squamous cell carcinoma Tca8113 cells and explore its probable mechanisms.

After treating Tca8113 cells with API, the cell proliferation, migration, and invasivecapacities were identified by te-trazolium salt colorimetry(MTT) assay, cell scratch test, and Transwell chamber test. Cellular immunofluorescence staining was used to localize mitogen-activated protein kinase 1 (MAPK1) and extracellular regulated protein kinase (ERK) 1/2 proteins. Western blot was used to detect the variations of the related protein expression levels.

① Through the MTT assay, API significantly inhibited cell proliferation (P<0.01). ②In the cell scratch test, the dis-tance of lateral migration after the API treatment was significantly shorter compared to the control group (P<0.01). ③The inva-sion rate in the lower chamber of the Transwell chamber was lower in the API group (P<0.01). ④ Cellular immunofluores-cence staining presented that the total-MEKK1 was localized in the cytoplasm, p-MEKK1 was localized in the nuclear mem-brane and cytoplasm, and p-ERK1/2 was localized in the cytoplasm and nucleus. ⑤ After API was applied to cells, the expres-sions of p-MEKK1 and p-ERK1/2 proteins significantly reduced (P<0.01).

Apigenin(API) significantly inhibits the proliferation, migration, and invasion of Tca8113 cells and its mecha-nism may be associatedwith the MAPK signaling pathway.

Dasatinib, as an oral multi-targeted inhibitor of BCR-ABL and SRC family kinases, has been widely used for the treatment of Philadelphia Chromosome Positive Leukemias in imatinib-acquired resistance and intolerance. The study aimed to develop and validate a simple and robust assay with a small volume of plasma based on liquid chromatography coupled with tandem mass spectrometry to determine the concentration of dasatinib and to investigate the impact of the cytochrome 3A4 inhibitors, including ketoconazole, voriconazole, itraconazole and posaconazole, on the pharmacokinetics of dasatinib in rats.

Thirty rats were divided randomly into five groups, control group (0.5% carboxymethylcellulose sodium), ketoconazole (30 mg/kg) group, voriconazole group (30 mg/kg), itraconazole group (30 mg/kg) and posaconazole group (30 mg/kg). After 150 μL blood samples were collected at 0, 0.5, 1, 2, 4, 6, 8, 10, 12, 24, and 48 h and precipitated with acetonitrile, the plasma concentration of dasatinib was determined through Fluoro- Phenyl column (150 mm×2.1 mm, 3 μm) in a positive ionization mode.

The results suggested that ketoconazole, voriconazole, and posaconazole could increase the AUC0-t of dasatinib to varying degrees while significantly reducing its clearance. However, there was no significant impact on the pharmacokinetics of dasatinib, co-administered with itraconazole except for the CL and MRT0-t of dasatinib. Additionally, voriconazole could significantly increase Cmax of dasatinib by approximately 4.12 fold.

These data indicated that ketoconazole, posaconazole and voriconazole should be cautiously co-administered with dasatinib or close therapeutic drug monitoring of dasatinib concentration, which might cause the drug-drug interaction.

As artificial intelligence and big data analysis develop rapidly, data privacy, especially patient medical data privacy, is getting more and more attention.

To strengthen the protection of private data while ensuring the model training process, this article introduces a multi-Blockchain-based decentralized collaborative machine learning training method for medical image analysis. In this way, researchers from different medical institutions are able to collaborate to train models without exchanging sensitive patient data.

Partial parameter update method is applied to prevent indirect privacy leakage during model propagation. With the peer-to-peer communication in the multi-Blockchain system, a machine learning task can leverage auxiliary information from another similar task in another Blockchain. In addition, after the collaborative training process, personalized models of different medical institutions will be trained.

The experimental results show that our method achieves similar performance with the centralized model-training method by collecting data sets of all participants and prevents private data leakage at the same time. Transferring auxiliary information from similar task on another Blockchain has also been proven to effectively accelerate model convergence and improve model accuracy, especially in the scenario of absence of data. Lipopolysaccharides Personalization training process further improves model performance.

Our approach can effectively help researchers from different organizations to achieve collaborative training without disclosing their private data.

The review prepared by a team of authors is based on in-depthscrutiny of data available in PubMed, Scopus, Cyberleninka, Clinical Trials, and Cochrane Library, eventually narrowing the search to a set of keywords such as tryptophan metabolites; plasma metabolomics profiling; metabolomics fingerprinting; gas-, liquid chromatography mass spectrometry; serotonin; melatonin; tryptamine; indoxyl sulfate; indole-3-acetic acid; indole-3-propionic acid; 5-hydroxyindole-3-acetic acid; gut microbiota and microbial metabolites. It provides a summary that outlines the pattern of changes in the level of indolic structure metabolites in a number of diseases and deals with the data from the field of human microbiota metabolites. In modern experimental studies, including the use of gnotobiological (germ-free) animals, it has been convincingly proved that the formation of tryptophan metabolites such as indole-3-acetic acid, indole-3-propionic acid, tryptamine, and indoxyl sulfate is associated with gut bacteria.
