Residual dipolar couplings (RDCs) have attracted attention in light of their great impact on the structural elucidation of organic molecules. However, the effectiveness of RDC measurements is limited by the shortage of alignment media compatible with widely used organic solvents, such as DMSO. Herein, we present the first liquid crystal (LC) based alignment medium that is compatible with pure D...

Filament formation in radioresistant mutants of Escherichia coli S after treatment with ultraviolet light and radiomimetic agents. J. Bacteriol. 83:38-42. 1962.-The effect of ultraviolet light and of five radiomimetic compounds on cell division, growth in liquid medium, and growth in solid medium of Escherichia...

The traditional approach to assessing eicosanoids in cell cultures by liquid or gas chromatography coupled to mass spectrometry involves time-consuming procedures such as derivatisation, degradation, solid-phase extraction, liquidliquid extraction, thin layer chromatography and sometimes, combination of all these procedures prior to the injection of the sample in the chromatography system. The ...

Environments contaminated with heavy metals negatively impact the living organisms. Ectomycorrhizal fungi have shown important role in these impacted sites. Thus, this study aimed to evaluate the copper-resistance of ectomycorrhizal fungi isolates Pisolithus microcarpus - UFSC-Pt116; Pisolithus sp. - UFSC-PT24, Suillus sp. - UFSM RA 2.8 and Scleroderma sp. - UFSC-Sc124 to different copper doses...

Embryogenic cultures of Araucaria angustifolia were established in a BM liquid medium supplemented with 2 μM 2,4-dichlorophenoxyacetic acid, 1 μM 6-benzylaminopurine and 1 μM kinetin (BM2) and in a BM medium free of growth regulators (BM0). During 42 days in culture, the cell growth pattern of both cultures was similar. The pH of the culture medium of both BM0 and BM2 underwent progressive redu...
