Curcumol induces apoptosis in SPC-A-1 human lung adenocarcinoma cells and displays anti-neoplastic effects in tumor bearing mice.

Curcumol is a sesquiterpene originally isolated from curcuma rhizomes, a component of herbal remedies commonly used in oriental medicine. Its beneficial pharmacological activities have attract significant interest recently. In this study, anti-cancer activity of curcumol was examined with both in vitro and in vivo models.

Expression and function of GSTA1 in lung cancer cells.

Glutathione S-transferase A1 (GSTA1) appears to be primarily involved in detoxification processes, but possible roles in lung cancer remain unclear. The objective of this study was to investigate the expression and function of GSTA1 in lung cancer cells. Real-time PCR and Western blotting were performed to assess expression in cancer cell lines and the normal lung cells, then verify the A549 cells line with stable overexpression.

[Lead adsorption by Trametes gallica, Bacillus cereus, and their co-immobilized biomaterial].

Taking Trametes gallica mycelium pellets, Bacillus cereus, and their co-immobilized biomaterial as bio-adsorbents, this paper studied their Pb2+ adsorption under effects of different contact time, medium initial pH value and Pb2+ concentration, and bio-adsorbent concentration, and compared the infrared spectra of the bio-adsorbents before and after Pb2+ absorption. The Pb2+ adsorption efficiency of the bio-adsorbents was the highest when the bio-adsorbent concentration was 2 g x L(-1), initial pH was 5.0, initial Pb2+ concentration was 50 mg x L(-1), and contact time was 1 h, with the Pb2+ biosorption rate being 71.

[Induce of laccase from Trametes gallica and its degradation on neutral dyes and organophosphorus pesticides].

The characteristics of the induction of laccase in Trametes gallica under different initial cultural pH, incubation time by different inducers were discussed, as well as the effects of temperature, pH and time on laccase degradation of six dyes and four organophosphors. The results showed that RB-bright blue, ABTS and o-toluidine affected the production of laccase at different levels, and ABTS was the best inductive agent in our test conditions, whose optimal initial pH and incubation time were 4.0 and 13 days, respectively.

[Biosorption of crystal violet and malachite green by Rhodotorula graminis Y-5].

With a shaker, this paper studied the characteristics of the biosorption of crystal violet and malachite green by Rhodotorula graminis Y-5 under different adsorption time, initial pH, and temperature, as well as the desorption and recycling use of the dyes. The biosorption of crystal violet and malachite green by R. graminis Y-5 had the peaks (93.
