To our best knowledge, STL-1 shows the lowest g CMC among the sugar-based surfac- 7) . Based on their analyses, the sodium salt possessed 1.42 succinoyl and 1.5 tetradecyl residues in the trehalose moiety.…”

“…Polysialogangliosides, lysoganglioside, and GM3 are reported to decrease PKC activity of HL60, brain, and A431, respectively (28). The critical micelle concentration of STL and MEL are 960 and 2.7 µM, respectively (17,18). As the effective concentration of STL (5 µM) is far less than the critical micelle concentration, while that of MEL (10 µM) is above CMC, MEL is assumed to form micelles, which could interact more on the cell membrane than STL.…”

“…It was apparent that the ester molecule itself was responsible for the activity, since neither sugar moieties nor fatty acids of STL and MEL in the free form proved to be effective in inducing differentiation of cells. On the other hand, it is reported that STL and MEL can act as anionic surfactant and nonionic surfactant with detergent properties, respectively (18,19). To confirm whether or not the ability of inducing differentiation of HL60 cells could be attributed to surface activities of these biosurfactants, we used analogues of STL and MEL.…”

Total cellular RNAs from a variety of fresh and culture-derived human hematopoietic neoplastic cell types at various stages of differentiation and human sarcoma, carcinoma, melanoma, and glioblastoma cell lines were enriched for poly(A)-containing sequences, fractionated by gel electrophoresis, and blot hybridized to a cloned DNA probe containing the transforming sequences (v-amv) of avian myeloblastosis virus (AMV), a virus known to cause myeloid leukemias in chickens. Expression of RNA sequences homologous to AMV was detected in all immature my-eloid and lymphoid T cells in addition to the single erythroid cell line examined, but not in mature T cells or in B cells, including lymphoblast cell lines derived from patients with Burkitt lym-phoma. In addition, induction of the cell line HL60, a promyelo-cytic leukemia line, to differentiate with dimethyl sulfoxide or reti-noic acid resulted in a reduction of the level of expression of the human cellular gene c-amy homologous to v-amy. There was no detectable c-amv mRNA in any of the solid tumor cell lines examined. Thus, expression of the human c-amy gene could be correlated with the stage ofdifferentiation ofdifferent hematopoietic cell types determined by morphologic and marker studies. Expression ofc-amy could not be correlated with the extent ofmethylation in HL60 and in HL60 induced to differentiate with dimethyl sulfoxide.

“…Biosurfactants show excellent surface activities despite their bulky molecular structures in comparison with conventional synthetic surfactants (1)(2)(3)(4). Therefore, studies of biosurfactants have been primarily conducted for the purpose of developing new functions as fine chemicals (5,6).…”

Remediation of a soil contaminated with cadmium or lead was performed by a soil washing process using aescin as a biosurfactant. The removal of cadmium and lead from the soil was evaluated as a function of aescin concentration and pH in a batch process. A 30-mM aescin solution was most effective in the removal of cadmium and lead at pH 6.8. Cadmium and lead migrated from the soil to the aescin-containing aqueous phase, depending on the pH value. We found that 41% of cadmium (pH 7.8) and 25% of lead (pH 2.8) in the soil matrix migrated into a 30-mM aescin solution. Also, the complexation of aescin with cadmium and lead ions was confirmed by Fourier transform infrared spectroscopy and electrical conductivity measurements. As a result, the maximal complexation capacity of aescin with metal ions was approximately aescin/cadmium = 2:1 and aescin/lead = 3:1 on a molar basis. It was suggested that aescin may sequester cadmium and lead ions by the carboxylic and saccharide moieties. Then, the complex of aescin with cadmium or lead may migrate to the aqueous phase as the result of dispersion. JSD 1, 247-250 (1998). FIG. 3. Shift of carboxylate bands in Fourier transform-infrared spectra of aescin and metal aescinates as evidence for the complexation of aescin with cadmium and lead. FIG. 4. Addition effect of lead ion (3 mM) on electrical conductivity of the aescin solution. FIG. 5. Addition effect of cadmium ion (3 mM) on electrical conductivity of the aescin solution.
