The development of a T7 RNA polymerase (T7 RNAP) expressing cell line i.e. BSR T7/5 cells marks an improvement reverse genetics for the recovery recombinant Newcastle disease virus (rNDV). is developed by transient transfection plasmid encoding RNAP gene rNDV rescue. However, expression decreases gradually over multiple passages and eventually hinders rescue rNDV. To address this issue, lentivi...

Background: Dimethyl Sulfoxide (DMSO) is a solvent most broadly used as a cryopreservative agent. Antitumor effects of DMSO is a recently recognized phenomenon. In this study, cytotoxic effects of DMSO on human monocytes and T leukemic cell lines has been investigated in vitro. Methods: Human leukemic T cells (Molt-4 and Jurkat) and monocytes (U937 and THP1) were cultured in complete RPMI medi...

      Current therapies for breast cancer are often limited by short-term efficacy due to the emergence of drug resistance. There has been increased interest in the use of naturally occurring compounds with chemopreventive and chemotherapeutic effects in the treatment of cancers. Saffron, dry stigmas Crocus sativus L., used in Iran as a spice, is known for its anticancer properties. In...

Abstract Biosynthesis of nanoparticles is the preferred route for fabrication biocompatible and cheaper drugs. In this study, extract major secondary metabolite from Helichrysum aureonitens , 3,5-dihydroxy-6,7,8-trimethoxyflavone, were used to synthesize silver zinc oxide nanoparticles. Spectroscopic microscopic techniques confirmed formation The flavone alone showed higher DPPH radical scaveng...

Background: β-Blockers have shown considerable cytotoxic, anti-tumor and anti-angiogenic effects. Metoprolol, a β-Blocker with anti-inflammation, anti-tumor and anti-angiogenic properties has been widely used for treatment of some cardiovascular diseases such as angina, hypertension, heart failure and myocardial infraction. Limited data exist about the cytotoxic effects of metoprolol on human c...

background: mentha species are widely used in traditional medicine mostly as anti-flatulence. nowadays, their usage as flavor and preservative in food, cosmetic and pharmaceutical industries has been developed. moreover, cytotoxic effects of some mentha species have been reported. objective: in this study, cytotoxic properties of mentha piperita, m. spicata, m. aquatica, m. crispa, m. pulegium ...

HIGHLIGHTS Observation of the antibacterial and cytotoxic effects CD.COM due to synergy between cyclodextrin, triazole TiO2 NPs. The activity against both gram positive negative bacteria. cytotoxicity cancer cells compatibility with fibroblast cells.

conclusions this study suggests that the il-7 level of chb patients may be related to tfh cells. in chb patients, il-7 possibly increases the level of tfh cells and hbv-specific cellular immune responses and thereby reduces the hbv dna level. background in patients with chronic hepatitis b (chb), the relation of interkeukin-7 (il-7) to either the t follicular helper cells (tfh cells) or to a sp...

The present study is the first to demonstrate the anticancer effects of a hexane extract from the brown algae Sargassum serratifolium (HES) on human cancer cell lines, including glioblastoma U87MG, cervical cancer HeLa and gastric cancer MKN-28 cells, as well as liver cancer SK-HEP 1 cells. Among these cancer cell lines, U87MG cells were most sensitive to the cell death induced by HES. HES exhi...
