phytochemical investigations of piper sarmentosum roxb., yielded four compounds; three amides, identified as 3-(3’,4’,5’-trimethoxyphenylpropanoyl) pyrrolidine, 3-(4’-methoxyphenylpropanoyl) pyrrole, n -(3-phenylpropanoyl) pyrrole and a sterol namely β -sitosterol . 3-(4’-methoxyphenylpropanoyl) pyrrole was found for the first time in this piper species. all chemical constituents were tested fo...
Scorpion venom toxicity is of major concern due to its influence on human activities and public health. We investigated the in-vitro process of cell death caused by two Iranian scorpions Odontobuthus doriae and Bothutus salceyi venom on human cell lines. The aim of this study was to provide further information about triggering cell death and suggestion of methods for the elimination of unwanted...
Several kinds of laboratory techniques are available to detect Clostridium difficile toxin in fecal samples. Because questions have been raised about the reliability of immunoassays compared to the accepted standard, cytotoxicity assay, we studied three enzyme immunoassays (EIAs) and one rapid EIA, which demonstrated relatively good sensitivities and specificities compared to cytotoxicity assay.
In this study cellular phosphatase activity, referred to as enzyme developed color (EDC) assay, was used for an in vitro assessment of cell proliferation and cytotoxicity. Optimum conditions were established and found to be 10 x103 cells / well at 37°C and 60 min incubation (for developing color). Under the same conditions a direct correlation between optical density (00) and cell number wa...
Statement of Problem: One of newly presented base metal alloys (Minalux) is produced according to VeraBond2 alloy (Ni- Cr base) composition. Several studies showed that, cytotoxicity of base metal alloys can be occurred due to corrosion and element release. Purpose: This study evaluated the biocompatibility of these two base metal alloys in three steps: as cast, after polishing and after porcel...
