Introduction and Aim: In this study, the interaction between Acanthamoeba culbertsoni Shigella sonnei was analyzed. addition, effect of monosaccharides on cytotoxicity A. analyzed through with macrophages. particular, activity protease Materials Methods: Association tests were performed for trophozoites Escherichia coli DH5 alpha, proteolytic enzyme all these tests, monosaccharides, e.g., manno...

In vivo tests available to determine the toxicity of mineral fibers are too expensive and time-consuming to be regularly employed in the evaluation of the potential health hazard posed by natural and man-made fibers. In vitro procedures, while economical, convenient and capable of ranking "relative toxicity," are uncertain predictors of specific lesions. Thus, it is of interest to compare the r...

Purpose The purpose of this study is to compare the physical, mechanical, and biocompatibility properties of a new dual-cure white mineral trioxide aggregate (D-W-MTA) and a commercial W-MTA. Materials and Methods Diametral tensile strength (DTS), water sorption (WSp), and water solubility (WSl) tests were performed. Cytotoxicity was observed in primary culture of human pulp fibroblasts (HPFs...

Previous studies have utilized in vitro alloy cytotoxicity tests to evaluate dental casting alloys. The purposes of this study were to: (1) evaluate the precision of the optical density and visual tests previously used, (2) evaluate a new test measuring absorbance of solubilized formazan dyes, and (3) test the correlation between these tests for cytotoxicity. Balb/c 3T3 cells were plated in 24-...

Background and objectives: Beside its nutritional role, caper (Capparis spinosa) has long been used as an analgesic, anti-inflammatory, anti-diabetic and anti-cancer remedy. In the present study, we tested whether this plant can make effective changes in Sirt3 and mitochondrial function in colorectal carcinoma cell line since mitochondrial dysfunction has long been imp...

Antigenic components were solubilized from a participate fraction of mouse lymphosarcoma 6C3HED at pH 9.0-9.5. Protein, lipid, and carbohydrate were present. Three measures of antigenicity were employed. Mouse cytotoxicity tests re vealed that the tumor fraction adsorbed a greater amount of rabbit antitumor antibody than did similar fractions of normal C3H mouse lymphoid tissues. In Schultz-Dal...

target cells in 995 tests and with lymphocytes from normal controls in 1099 tests. The average reactivity was significantly greater with lymphocytes from normal persons in 3 of the 7 established lines and 2 of 12 short-term cultures. In only 1 short-term bladder tumor culture was there indication of greater cytotoxicity produced by lymphocytes from bladder cancer patients than by cells from nor...
