  • The Effect Of Binary Mixture Of Metals In Hepg2 Cells

    The data from the cytotoxicity study was analyzed using factorial analysis of variance (ANOVA) with statistical software Dell Statistica (data analysis software system) version 12, Dell Inc, Tulsa, USA, country (2015) available from http://www.Software.dell.com. The data from total GSH and ROS assays were analyzed using “one-way ANOVA followed by Dunnett’s multiple comparison tests with GraphPad Prism version 6.00 for Windows (GraphPad Software, La Jolla California USA, http://www.graphpad.com.anova using Graphpad software). The effect of binary mixture of metals (Cd + As, Cd + Pb and As + Pb) and B[a]P + metals (B[a]P + As, B[a]P + Cd and B[a]P + Pb) on cytotoxicity in HepG2 cells are presented in Table 4 and Figures 1 to 6. Arsenic (As), Cadmium (Cd) or lead (Pb) either alone (main effect) or binary combinations, Cd + As, Cd + Pb and As + Pb (interaction effect) caused significant cytotoxicity to HepG2 cells (Table 1, Fig. 1…

  • Basso Bresnahan Scale

    minutes. In order to determine the proportion of PI-positive cells, the nuclei were labeled with propidium iodide (PI) and the cover marked with Neutral Balsam. All negative control sections were incubated in PBS without primary antibodies to further confirm the specificity of the antibodies. Five random fields of each animal were selected and the images were visualized by the use of a fluorescence microscope (Olympus BX51, NIKON, Japan). The Statistical Analysis The data in this report were…

  • Biaxial Tensile Test

    tissue rings and were fixed in 10% neutral buffered formalin solution. Then, the samples were paraffin embedded, cut into thin sections, and mounted on microscopic slides. The slides were stained by a Modified Movat 's Pentachrome staining protocol. Three representative images, each of which covered approximately 1/3 of the media layer, were captured and used to obtain the average contents of the tissue components in this layer. Aortic aneurysms are attributed to medial degeneration [25]; hence,…

    amount of ATP and ADP were measured by the standard curve and then the ratio was calculated. 2.8. Hippocampal mercury measurement Mercury concentration was measured in brain hippocampus by cold vapor atomic absorption spectrometry (CVAAS) (Semi-automated Mercury Analyzer, model Hg-201, Sanso Seisakusho Co. Ltd., Tokyo, Japan). Briefly, a homogenized sample (0.5 g of wet weight) was digested with a mixture of 2 mL of nitric acid-perchloric acid 1 + 1 (HNO3-HClO4) and 5 mL of sulfuric acid…

  • Essay On Fexofenadine

    respectively. However, at nine months of on-going stability point the microbiological count raised at a relatively higher rate with TVAC of 1475 CFU/ml. The breaking point of the generation time for the bacteria was expected to be between 3-6 mo with an slow initial rate from 0-3 mo and fast one from 6-9 mo. Since no count was detected till the point of 6 mo, the generation time was estimated to be between 1.89 to 41.28 mo (56.67 to 1238.49 d) with the average middle point (5 CFU/ml) to be 6.28…

    temperature for 10 min, the absorbance of the mixture was read at 562nm against a deionized water blank using an Ultraviolet-Visible (UV-vis) spectrophotometer PERSEE TU-1810 UV-VIS (Persee Instruments co. Ltd, Beijing-China). EDTA was used as the positive control. The percentage of the inhibition of ferrozine-Fe2+ complex, expressed chelating activity was calculated using the following equation: Chelation (%)=100(1-As/Ac) Where As is absorbance of sample or EDTA, and Ac is absorbance of…

  • Ondek Pty Ltd: A Case Study

    gMFI value as 0%. The percentage of activation of THP-1 cells exposed to various concentrations of H. pylori product (in the presence of LPS) was calculated by comparing the CD80 gMFI values of the samples to the gMFI values of negative and positive controls (Fig. 4B). The values (y axis) were then graphed against product concentration (x axis) (Fig. 4C) and a 4 parameter logistic (4PL) curve-fit was performed (Fig 4D). % activation= (CD80 gMFI (Sampl〖e)-CD80 gMFI (negative control)〗_ )/(CD80…
