Evaluating the effects of simulated microgravity on mouse fibroblastDiscussion In this study, simulated microgravity condition reduced the proliferation and nuclear area of mouse fibroblasts compared to the control group. Mouse fibroblasts being rounder in shape might be due to an increase in cell membrane actin and a decrease in central actin fibers. This showed the important role of actin in determining c...

Utilization of the light density to reduce the development of Lyngbya sp. and their growth on Caulerpa lentillifera J. Agardh in a recirculating aquature systemDISCUSSION This experiment indicates that the C. lentillifera under a light density of 20 μmol photons m-2.s-1 had almost no Lyngbya sp. present on their branches after 28 days. In addition, new branches were emerging along the stolons. On the opposite, the seaweeds under a light density of 40 were covered by Lyngbya sp. and about to die at...

Osteogenesis activity of fractions extracted from clinacanthus nutans (burm. F) lindauEffects of C. nutans EtOH and EtOAC fractions on bone mineralization activity of MC3T3-E1 osteoblast cells The matrix mineralization stage is the third (final) stage of the osteoblast differentiation process. At the end of the mineralization, calcium deposits (bone mineralization) can be observed with appropriate staining. The results in Fi...
