  • The main goal of this study was to establish callus cell suspension cultures of Medicago sativa L. ‘Elçi’ and natural tetraploid Trifolium pratense L. and to compare the isoflavone production of the cultures to the original plants. The callus culture was transferred to liquid Murashige and Skoog media (MS3 and MS5) in order to establish the cell suspension cultures.

  • In many parts of the world the primary source of animal protein for humans is finfish. The intensive culture of finfish has grown significantly since the 1980s partly because of the dramatic decline in the natural fish stocks and the increase in fish consumption by the ever-increasing population. For example, the worldwide consumption of fish between 1990 and 1997 increased by 30% while the capture fisheries increased only by 9%.

  • We report here the protocol for Zedoary (Curcuma zedoaria Roscoe) callus and cell suspension cultures. The MS medium supplemented with 2% sucrose, 1.0 mg/l 2,4-D and 1.0 mg/l BA was effective for callus induction from in vitro leaf-base explants of Zedoary. During subcultures, secondary proliferated calli were subsequently produced from initial induced calli on the MS medium with 0.5 mg/l 2.4-D and 0.5 mg/l BA. These calli were light yellow in color, compact and friable.

  • We established cell suspension culture on ginseng and some attempts have been made to increase ginsenoside yield of ginseng cell culture through manipulation various culture factors and process variable. The maximum biomass yields of cell suspension culture of ginseng was obtained in medium containing 2,4-D as compared to IBA or NAA. However, ginsenoside production was much higher in IBA or NAA containing medium and 7 mg/L IBA was determined to be optimal for cell growth (10.1 mg/L DW) and ginsenoside production (7.2 mg/g DW)....

  • We investigated the effects on ginseng cell and ginsenoside production when macro element concentrations were manipulated in the culture media. Biomass growth was greatest in the medium supplemented with 0.5 strength NH4NO3, whereas ginsenoside accumulation was highest (6.5 mg/g DW). At levels of 1.0 strength KNO3, cell growth was maximum, but 2.0 strength of KNO3 led to the greatest ginsenoside content (6.1 mg/g DW).

  • Isn’t it strange that the animal we used to be developed into the creature that we now are? How – and why – did human intelligence and culture evolve? How did we evolve minds, philosophies and technologies? And now that we have them, where are they taking us? The orthodox answer to these questions looks inside our brains to see what they are made of and how the various components operate.

  • Quinolinic acid (QUIN) excitotoxicity is mediated by elevated intracellular Ca 2+ levels, and nitric oxide-mediated oxidative stress, resulting in DNA damage, poly(ADP-ribose) polymerase (PARP) activation, NAD + deple-tion and cell death. We evaluated the effect of a series of polyphenolic compounds [i.e. epigallocatechin gallate (EPCG), catechin hydrate, curcu-min, apigenin, naringenin and gallotannin] with antioxidant properties on QUIN-induced excitotoxicity on primary cultures of human neurons....
