objective(s): this study aimed to find out whether the chick cardiomyocyte micromass (mm) system could be employed to predict the teratogenecity of common environmental factors. different multivitamins and over the counter drugs were used in this study.   materials and methods: white leghorn 5-day-old embryo hearts were dissected and trypsinized to produce a cardiomyocyte cell suspension in dul...

objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...

objective(s): hepatitis c is a major cause of liver failure worldwide. current therapies applied for this disease are not fully effective and produce side effects in most cases. non-structural protein 3 helicase (ns3) of hcv is one of the key enzymes in viral replication and infection. therefore, this region is a promising target to design new drugs and therapies against hcv infection. the aim ...

objective(s): juglone is isolated from many species of the juglandaceae family and used as an anti-viral, anti-bacterial, and anti-tumor therapeutic. here, we evaluated juglone-induced antitumor effect in ovarian cancer skov3 cells. materials and methods: mtt assay was performed to examine juglone anti-proliferative effect. cell cycle and apoptosis were studied using flow cytometry in juglone-tr...

The prenylated flavonoids, topazolin [5,7,4'-trihydroxy-3-methoxy-6-(3,3-dimethylaIlyl)flavone], piscerythrone [5,7,2',4'-tetrahydroxy-5'-methoxy-3'-(3,3-dimethylallyl)isoflavone] and piscidone [5,7,4',5'-tetrahydroxy-2'-methoxy-6'-(3,3-dimethylallyl)isoflavone] were meta­ bolized by Aspergillus flavus and Botrytis cinerea to give a variety of products. Topazolin and piscerythrone were converte...
