the present study was intended to standardize the protocol for the synthesis of silver nanoparticles (agnps) using aqueous extract of dictyota bartayresiana j.v. lamouroux and evaluate cytotoxic potentials using brine shrimp bio-assay activity and trypan blue dye exclusion method. the reduction of pure ag+ ions was monitored by measuring the uv-vis spectrum of the solution at 200-900 nm and the...

background and objective: in addition to the use of chemicals in food, pharmaceutical, cosmetic and hygiene industries, use of herbal and natural compounds have also increased. it seems natural ingredients compared with the chemical components show less side effects, such as mutagenicity and carcinogenesis however, their use can also be associated with side effects and toxicity. some significan...

There have been efforts to overcome the problem in treatment of cancer using medicinal plants. It has been shown that Citrus essential oil of contains different terpens with antitumor activities. In this study we sought to determine the cytotoxicity of essential oils of Iranian Citrus limon (L.), C. medica (L.), C. sinsensis (L.) peels on cancer cell lines. Essential oils were prepared by hydr...

Background: Pharmaceutical industries around the world are struggling for finding new approaches to fight cancer and many researchers are involved in this process to find new drug candidates. Aims: The current study aimed at investigating the new marine natural products with anticancer potential from the three Persian Gulf Holothuria sea cucumbers. <st...

     Extracts derived from Viscum album have been shown to kill cancer cells in vitro. Some studies have noted that different species of this plant collected from around the world displayed cytotoxic effects in different extents. In the present study, we evaluated the effects of Iranian mistletoe extracts on five cancer cell lines. Plants growing on hornbeam tree (Carpinus...

The present study was carried out to evaluate the cytotoxic effects of aqueous (AE) and ethanolic (EE) extracts of Artemisia herba alba on human laryngeal carcinoma (Hep-2) cell line and murine mammary adenocarcinoma (AMN-3) cell line in vitro. The in vitro cell growth assay showed that there were timeand concentration-dependant cytotoxic effects of both extracts on the tested cell lines. The r...

Cancer is a major cause of death worldwide and causes serious problems in human life. It is developed by uncontrolled growth of a cell or a group of cells. There are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. Caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. The...

The objective of this study was to evaluate the effects of metal ions, which may be released from orthopedic or dental implants, on osteoblast metabolism and differentiation. ROS 17/2.8 cells were cultured in F-12 medium for 7 days. Then Al+3, Co+2, Cr+3, Ni+2, Ti+4, and V+3 were added at concentrations less than their cytotoxic concentrations. After 3 days, DNA synthesis, succinate dehydrogena...
