Article Synopsis
- Interferon gamma (IFN-γ) is crucial for the immune system in vertebrates, and its study in fish reveals insights into the evolution of innate immunity.
- Phylogenetic analysis indicates two separate groups of IFN-γ proteins in fish, alongside evolutionary details on their receptors, including gene duplications and the prominence of the IFN-γ receptor 1 (IFN-γR1) across different fish species.
- Structural studies, including the crystal structure of olive flounder IFN-γ, show that while the overall structure resembles known IFN-γ proteins, significant differences exist, highlighting evolutionary variations among species.
Article Synopsis
- Two strains, R89-1 and R90, found in poppy seed waste were identified as a new species within the Agrobacterium genus after thorough phenotypic and genotypic analysis.
- * These strains exhibited unique characteristics, including salt sensitivity and the ability to biotransform morphine alkaloids, differentiating them from other Agrobacterium species.
- * The proposed name for the new species is Agrobacterium bohemicum, with strain R90 designated as the type strain.
Fat and vitamin A stability in the presence of Ronoxan A and other antioxidants.
Int J Vitam Nutr Res
February 1983
The effect of the antioxidant Ronoxan A and of two of its components (ascorbyl palmitate, lecithin) and of tocopheryl acetate was tested for the stabilization of fats and retinyl acetate. In the present study, results obtained in sunflower oil, soybean oil, milk fat and in the mixtures of these fats in concentrations corresponding to their levels in the Czechoslovak Infant Formula (Feminar) are compiled. The antioxidant levels applied, i.

View Article and Find Full Text PDFOlive oil was converted into methyl esters which were autoxidized at 60 degrees C. The composition of oxidized products was determined by the comparison of infrared spectra and NMR spectra of the original and acetylated samples, the sample reduced with potassium iodide and the acetylated reduced sample. Oxidized products were separated by preparative thin layer chromatography on silica gel and characterized by selective detection and by infrared spectrometry of the fractions.
