The Anti-Proliferative and Anti-Angiogenic Effect of the Methanol Extract from Brittle Star

Background: Anti-angiogenic therapy is a crucial step in cancer treatment. The discovery of new anti-angiogenic compounds from marine organisms has become an attractive concept in anti-cancer therapy. Because little data correlated to the pro- and anti-angiogenic efficacies of Ophiuroidea, which include brittle star, the current study was designed to explore the anti-angiogenic potential of bri...

Evaluation of the cytotoxic effect of the Brittle Star (Ophiocomaerinaceus) dichloromethane extract and doxorubicin on EL4 cell line

Leukemia is a blood disease which is caused by the inhibition of differentiation and an increased proliferation rate. Nature has been known as a rich source of medically useful substances. High diversity of bioactive molecules extracted from marine invertebrates, makes them ideal candidates for cancer researches. The study has been done to investigate cytotoxic effects of dichloromethane brittl...

Scaling relations in dynamical evolution of star clusters

We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...
