Comparison of amphibian whole-cell and cell-free activity towards different transferrins

Antioxidant activity of polyphenolic myricetin in vitro cell-free and cell-based systems

Myricetin (Myc) is one of the most important flavonoids in diet due to its abundance in foods with the highest antioxidant activity. The antioxidant activity of Myc was studied in cell-free and cell-based systems to evaluate the ROS protection efficiency of Myc. The studies were based on the assessment of reducing power of Myc according to ferric ion reduction and intracellular ROS level measur...

Comparison of cytotoxic activity of some Iranian Stachys spp. extracts on different cancer cell lines

The genus Stachys belongs to Lamiaceae family with about 300 species and worldwide distribution. In the present study, the cytotoxic activity of four fractions of different Satchys species (S. byzatina C. Koch., S. inflata Benth., S. setifera Ten. and S. persica Gmel.), has been investigated against HT-29 (colon carcinoma), Caco-2 (colorecta...

Isolation of a Penicillin Acylase Producing E.coli and Kinetic Characterization of the Whole Cell Enzyme Activity

Penicillin acylase (EC 3.5.1.11) has been a target of study for a long time because of its pivotal role in the deacylation of the penicillin into the 6- aminopenicillanic acid (6-APA) and the side-chain organic acids. This property of penicillin acylase has been exploited commercially for large scale production of 6-APA, which is the key intermediate in the manufacture of semi-synthetic penicil...

Evaluation of Cell Growth Inhibition of Bifidobacterium Bifidum Cell-free Supernatant Extract on 4T1Tumor Cell Lineage

Background: Cancer is amongst the leading reasons of death in all parts of the world. Breast cancer is also responsible for the largest number of deaths among women population. Several studies confirmed that Bifidobacterium bifidum as a probiotic meaningfully inhibited breast cancer development. The present study aimed to investigate the effect of B. bifidum supernatant on the cell growth inhib...
