background: the aim of this study was to investigate the effect of methanolic extract of achillea millefolium l. (mea) on the antiproliferative activity of bleomycin on human prostate cancer and normal skin cells. materials and methods: human prostate cancer cell (du-145) and human non-malignant fibroblast cell (hfff2) were treated with mea at various concentrations ( 20, 100, 500, 1000 and 200...
The present study aimed to determine the cellular toxicity and anticancer characteristics of six species of Cyan bacteria living in Geno hot spring on cervical cancer cell lines. For this purpose, the cyto toxicity of methanol extracts from Geno hot spring Cyanobacteria including Leptolyngbya tenuis, Chroococcus minutes, Gloeocapsarupestris, Oscillatoria articulate, Chroococcus namiculata and S...
تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...
Graphene has exhibited wide applications in nanotechnology, especially in biomedicine because of its unique physical and chemical properties. The degree of toxicity of graphene materials depends on various factors such as surface charge, physicochemical properties, toxicity determination methods, and cell line. Direct contact of the very sharp edges of graphene with the cell membrane is one of ...
Toxicity bioassays are important tools to determine biological effects of chemical agents on species. The questions remained on, what effects have been imposed on each of the different molecular site of cells by chemical exposure and how to find a pattern for chemical toxicity. To address the questions, HepG2 cell lines were exposed to the different concentrations of cisplatin for 24 hours to r...

Introduction: Cell culture is a process in which the cells ware isolated from original tissue, dispersed in liquid media and then placed in culture plate where the cells adhere together and propagate. Today, this method is used for assessment of cell toxicity, its mechanisms and effect of different compounds on intracellular components. Methods: Clonogenic assay was used for assessment of cel...
The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...
Introduction: Silver nanoparticles (SNPs) have recently been suggested to increase the antimicrobial properties of soft liner materials. However, their safety remains a matter of debate. This study aimed to evaluate the cytotoxicity of Mucopren® soft silicone liner material (Mucopren; Kettenbach, Germany) incorporated in SNPs. Methods: The SNPs with ...
