Abstract Cytochrome P450 3A4 ( CYP 3A4) is quantitatively the most important enzyme in adults. It suggested that genetic polymorphisms may influence rate of metabolism and elimination substrates human beings. Ibrutinib an anticancer drug primarily metabolized by 3A4. The aim this study was to systematically investigate effects 22 protein variants on ibrutinib vitro . When compared with wild‐type 3A4.1, two 3A4.17 3A4.24) had no detectable activity; five 3A4.10, .11, .18, .23 .33) exhibited...

The aim of this study was to the effect celecoxib on agomelatine metabolism in vitro and vivo.Ten healthy male Sprague-Dawley rats were randomly divided into 2 groups: Group A (control group) B (30 mg/kg celecoxib). Then a single dose 20 administered orally 30 min after administration celecoxib. In an study, with series concentrations added incubation mixture containing recombinant human CYP2C9, or rat liver microsomes determine half-maximal inhibitory concentration agomelatine. Moreover,...

BACKGROUND The AJCC staging system is inadequate for use in patients with thyroid carcinomas. Here, we aimed to establish a nomogram cancer, and compare its prognostic value the adults diagnosed carcinoma. MATERIAL AND METHODS Patient records were obtained from Surveillance, Epidemiology, End Result database. 8491 included divided into modeling cohort (n=5943) validation (n=2548). variables selected using backward stepwise selection method Cox regression, prognosis was constructed. In...

Elderly people and patients with colorectal cancer (CRC) are both at high risk of malnutrition. Therefore, it is great significance to explore suitable malnutrition screening diagnostic indicators for elderly CRC. Recently, the Global Leadership Initiative on Malnutrition (GLIM) proposed new criteria The aim this article was evaluate value GLIM in patients. We explored relationship between GLIM-malnutrition, post-operative complications long-term prognosis patients.Elderly (aged ≥65 years)...

Abstract The objective of this study was to evaluate the effect apatinib on pharmacokinetics venlafaxine and O‐desmethylvenlafaxine in SD rats inhibitory effects rat human liver microsomes. Twenty‐one male were randomly divided into three groups (n = 7): group A (multiple dose 40 mg/kg for 7 days), B (single apatinib) C (the control group). All samples measured by UPLC ‐ MS / . results indicated that a single increased AUC (0‐t) , (0‐∞) max both significantly, while Vz/F CL z/F decreased. As...

Objective . To discuss the effects of genistein on metabolism celecoxib in vitro and vivo. Method In vitro, were studied using rat human liver microsomes. vivo, pharmacokinetics was evaluated rats with or without genistein. Fifteen Sprague-Dawley (SD) randomized into three groups: (A group), 50 mg/kg (B 100 (C group). Single dose 33.3 orally administered 30 min after ig. At 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24 h administration, 300–400 µl blood samples collected concentration analyzed by...

Subcellular localization of photosensitizers is thought to play a critical role in determining the mode cell death after photodynamic treatment (PDT) leukemia cells. Using confocal laser scanning microscopy and fluorescent organelle probes, we examined subcellular merocyanine 540 (MC540) murine myeloid M1 WEHI 3B (JCS) Two patterns were observed: JCS cells, MC540 was found localize on plasma membrane mitochondria; lysosomes. The relationship between PDT-induced apoptosis investigated....

Objective: To investigate the impact of resveratrol on metabolism ibrutinib in vitro and vivo.Methods: In vitro, rat liver microsomes (RLM) human (HLM) were used to study. vivo, 18 male SD rats randomly divided into three groups (n = 6): multiple dose 100 mg/kg for consecutive 7 days (Group A), single B), C). Processed samples analyzed by UPLC–MS/MS.Results: Resveratrol showed inhibition RLM HLM vitro. The IC50 was 8.745 µM 7.789 HLM. Furthermore, Groups A B both increased AUC reduced CLz/F....

Olmutinib (Olita™) is an oral third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) which used to treat non-small cell lung cancer (NSCLC). A simple, rapid, and sensitive method based on ultra-performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS) has been developed for the determination of olmutinib. Sample preparation was performed following simple one-step protein precipitation with acetonitrile. internal standard (dasatinib) were...

Androgens are essential hormones for testicular development and the maintenance of male fertility. Environmental factors, stress, aging, psychological conditions can disrupt androgen production, impacting signaling pathway consequently spermatogenesis. Within testes, testosterone is produced by Leydig cells acts on Sertoli activating receptor (AR), which then translocates to nucleus function as a transcription factor. Despite clinical correlations between low levels diminished sperm quality,...
