Elaboration of amorphous SiCPc: materials was performed using a conventional thermaly activated CVD at 100012003C from the '1MS-NH3-H2 system. 'I'he influence on the deposition rate and the composition was investigated using an experimental design by varq-ing: deposition temperature, pressure and hTb flow rate. A set of 16 samples SiCxNy with x!y ranged from 0.0.1. to 1.69 was prepared. .4ccura...

DNA repair is critical for successful chemo- and radiotherapy of human tumours, because their genotoxic sensitivity may vary in different types of cancer cells. In this study we have compared DNA damage and the efficiency of its repair after genotoxic treatment with hydrogen peroxide, cisplatin and gamma-radiation of head and neck squamous cell carcinoma (HNSCC). Lymphocytes and tissue cells fr...

In the last decade, green synthesis of nanoparticles has had a prominent role in scientific research for industrial and biomedical applications. this current study, silver nitrate (AgNO3) was reduced stabilized with an aqueous extract Thelypteris glandulosolanosa (Raqui-raqui), forming (AgNPs-RR). UV-vis spectrophotometry, dynamic light scattering (DLS), scanning transmission electron microscop...

Some studies demonstrate that gallic acid (GA) and myricetin (MYR) isolated from Rhus trilobata provide the therapeutic activity of this plant against cancer. However, few reports both compounds could also have potential in ovarian Therefore, evaluating cytotoxic GA MYR cancer cells determining possible action mechanism present are important. For purpose, SKOV-3 (ovarian adenocarcinoma; HTB-77™...

Hepcidin is an innate immune element which decreases the iron absorption from diet and iron releasing from macrophage cell. In contrast to the chemical iron chelators, there has been limited effort applied to the specific use of hepcidin as a new drug for decreasing the iron overload. Hepcidin is produced in different biological systems. For instance, E-coli is used for human hepcidin expressio...

A urokinase-type plasminogen activator was purified from conditioned media of several human cell cultures, but preferably from the human lung adenocarcinoma line CALU-3 (ATCC, HTB-55), using a combination of chromatography on zinc chelate-Sepharose, SP-Sephadex C-50, and Sephadex G-100. Final yields of 65-100 micrograms/liter of starting material were obtained with a 290-fold purification facto...
