• Evaluating the effects of simulated microgravity on mouse fibroblastEvaluating the effects of simulated microgravity on mouse fibroblast

    Discussion 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 systemUtilization of the light density to reduce the development of Lyngbya sp. and their growth on Caulerpa lentillifera J. Agardh in a recirculating aquature system

    DISCUSSION 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...

  • New record for Asia-Pacific of protoperidinium anomaloplaxum (peridiniales, dinophyceae) from Vietnamese watersNew record for Asia-Pacific of protoperidinium anomaloplaxum (peridiniales, dinophyceae) from Vietnamese waters

    Morphological notes The shape and tabulation of the Vietnamese material of Protoperidinium anomaloplaxum is identical to the type description, Peridinium anomaloplaxum Balech, 1964. The cingular plates C1 and C3 were very narrow (Figs. 1b & 2b) (Balech, 1964, p. 29, pl. III, Figs. 34, 41; Balech 1988, pl. 22, Fig. 9). However, in a few case...

  • Food selection of maize weevil sitophilus zeamais (motschulsky)Food selection of maize weevil sitophilus zeamais (motschulsky)

    CONCLUSIONS In maize grain granaries in Son La, 5 weevil species, including Sitophilus zeamais, Ahasverus advena, Carpophilus dimidiatus, Carpophilus hemipterus, and Carpophilus dimidiatus, frequently appear among maize grains with high ratios. Meanwhile, only 4 were encountered in rice and soybean samples. Moreover, among these three types...
