Hexavalent chromium, Cr(VI), is a highly toxic species, while trivalent chromium, Cr(III), is an essential trace element for humans and other organisms. In the present work, a simple, rapid, and efficient procedure for water treatment of Cr(VI) is described. Active carbon (AC) was chemically treated with HCl and NaOH for the formation of surface modified Acidic-AC and Basic-AC sorbents, respectively. In addition, AC sorbent was treated with HNO3 as an oxidizing agent and sodium sulfite as a reducing agent for the formation of Ox-AC and Rd-AC sorbents, respectively.

In this study, the effects of elicitors on the growth and bioactive ingredients of Panax vietnamensis cell mass are evaluated. The medium composition was fixed with a MS liquid medium supplemented with 6.42 mg/ml NAA, kinetin of 0.11 mg/l, saccharose of 34.3 g/l, a pH of 5.6-5.8, temperature of 24-26o C, conducted at 50 rpm, and culture time of 14 days. The results showed that the best elicitor is jasmonic acid, at a concentration of 100 µmol/l, and for an optimal exposure of the bioactive ingredients to jasmonic acid for 12 days and 14 days after starting the culture.

The major components of stem-leaf are: (Z)-3-hexen-1-ol, trans-caryophyllene, αfarnesene, copaene while the major components of flower are: α-pinene, 2-β-pinene, β-myrcene, limonene, α-caryophyllene, epibicyclosesquiphellandrene. The essential oil of the stem-leaf showed cytotoxic activities in vitro on RD and Hep-G2 cancer cells with the IC50 values of 16.1 and 19.9μg/ml, respectively. The study on the plant is being continued.

Two new conjugates of murrayafoline A with zerumbone and artemisinin 3, 11 were prepared by N-alkylation, in which, compound 3 was synthesized from two consecutive Nalkylation reactions. Their cytotoxicity was evaluated on four human cancer cell lines Hep-G2, LU, RD and Fl. The result showed that both compounds exhibited no activity against the tested cell lines.

From the lipopolysaccharide of the deep rough mutant I-69 Rd–/b+ of Haemophilus influenzae two oligosaccharides were obtained after de-O-acylation and separation by high-performance anion exchange chromatography. Their chemical structures were determined by one- and two-dimensional 1H-, 13C- and 31P-NMR spectroscopy as aKdo-4P-(2 fi 6)-bGlcN-4P-(1 fi 6)-aGlcN-1P and aKdo-5P-(2 fi 6)-bGlcN-4P-(1 fi 6)-aGlcN-1P.

We discuss mechanisms that enable the scaling of pattern with size during the development of multicellular organisms. Recently, we analyzed scaling in the context of the early Xenopusembryo, focusing on the determination of the dorsal–ventral axis by a gradient of BMP activation.
