However, surgical intervention and chemotherapy provide only limited benefits for the recovery and survival of patients. The anti-carcinogenic effect of genistein has attracted attention due to epidemiological studies showing that soybean consumption is associated with a decrease in incidence of cancer. There are limited studies on the effects of genistein in colorectal carcinoma cells. We aimed to investigate the cytotoxic, genotoxic, and apoptotic effects of genistein in SW480 and SW620 colon adenocarcinoma cells treated with 5-fluorouracil, the basis of chemotherapy, and TRAIL ligand, the mediator of apoptosis, both alone and in combination. Materials and Methods: The cytotoxicity and genotoxicity were determined by MTT assay and comet assay, respectively. The apoptotic effects were evaluated by RT-PCR assay, with the additional use of Annexin V FITC, mitochondrial membrane potential, caspase 3, 8 and 9 activity, reactive oxygen species assay kits. Results: According to our findings, genistein, 5-fluorouracil and TRAIL had synergistic apoptotic effects as a result of DR5 up-regulation, ROS production, and DNA damage, which was mediated by increased caspase 3, 8 and 9 activity and decreased mitochondrial membrane potential. Conclusion: The applied combinations of these compounds may contribute to the resistance problem that may occur in the treatment of colorectal cancer, with the decrease in DcR1 and XIAP genes.","PeriodicalId":23378,"journal":{"name":"Turkish Journal of Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42116508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rats were divided into four groups: (a) treated with fibroblast cells, (b) collagen hydrogel, (c) collagen cultured with fibroblast cells, and (d) control group. Microscopic and histological (H&E staining and Mason trichrome staining), measurement of wound surface with Image J, skin density and thickness by the ultrasound probe, and skin elasticity with cutometer tool was used to evaluate the wound healing in a days , 14, and 21 after the treatment. RESULTS: The results showed that the treatment of diabetic wounds with fibroblast cells cultured in collagen hydrogel greatly reduces inflammatory responses in the skin tissue and significantly accelerates the healing process.

Deiodinases enzymes control the metabolism and homeostasis of thyroid hormones (THs). Deiodinases type III (DIO3) gene encodes deiodinase type 3 enzyme (D3), the genetic polymorphisms of this gene could affect the levels of THs and then the response to LT4 treatment. This study aims to investigate the single nucleotide polymorphism (SNP), rs1190716; C>T, of DIO3 as a candidate genetic variant that might affect the clinical response to LT4 treatment. Materials and Methods: Two hundred Iraqi hypothyroid female patients who were aged 40 years or older were enrolled in this cross-sectional study. All of them were already on the LT4 treatment for at least 4 months. Thyroid hormones (thyroxin (T4), triiodothyrionine (T3), revers riiodothyrionine (rT3) and diiodothyrionine (T2)) were estimated. Allele specific-polymerase chain reaction technique was performed to detect the rs1190716; C>T SNP. Results: The genotypes distribution of rs1190716; C>T SNP was 10 (4.5%) for the wild type (CC), 50 (22.7%) for the heterozygous mutant type (TC), and 160 (72.7%) for the homozygous mutant type (TT). The patients were divided into three groups according to their genotypes. Significant differences were found in the levels of T4, T3 and T2 among the groups of the patients (P=0.019, P=0.039, P= 0.032, respectively) Conclusion: The rs1190716; C>T SNP could affect the activity of the D3 enzyme and the metabolic homeostasis of the THs, therefore rs1190716; C>T SNP could have an impact in the therapeutic response to LT4 in Iraqi female patients with primary hypothyroidism.

Methods : A cross-sectional design was employed. A 26-item online survey was utilized to gather data about the patients' knowledge of and attitudes toward the influenza vaccine as well as their status as influenza vaccine recipients. Results : A total of 19% of the 564 study participants had an influenza vaccination. The majority (81%) of individuals reported inconsistent vaccination uptake. The most important factor affect vaccination is the belief the flu is not a threat (39%) and they were not advised by their doctors about the vaccination (32%). Participants with no health insurance and with public insurance had a lower level of vaccination in comparison with private insurance (p = 0.008). Conclusions : The adult population of Jordan with chronic diseases have subpar immunization rates. Also revealed is a blatant misunderstanding about the value of routine influenza vaccination.

However, this can be quite difficult due to various matrix effects and the problems of chromatographic separation of analytes. In the current study; for the first time, an optimized and fully validated fully according to FDA and EMA Bioanalytical Validation Guidance HPLC-EC method was developed for the simultaneous analysis of nine neurotransmitter compounds which are dopamine (DA), homovanilic acid (HVA), vanilmandelic acid (VA) serotonin (SER), 5-hydroxyindole-3-acetic acid (5-HIAA), 4-hydroxy-3-methoxyphenylglycol (MHPG), norepinephrine (NE), 3,4 dihydroxyphenylacetic acid (DOPAC) and 3-methoxytyramine (3-MT) and simultaneously determined in rat brain samples. METHODS: The separation was achieved with 150 mm × 4.6 mm, 2.6 μm F5 Kinetex (Phenomenex, USA) column isocratically, and analysis was carried out HPLC equipped with DECADE II electrochemical detector. RESULTS: The method exhibited good selectivity and correlation coefficient values for each analyte’s calibration curves were >0.99. The detection and quantification limits ranged from 0.01 to 0.03 ng/mL and 3.04 to 9.13 ng/mL, respectively.
