“…Unsaturated fatty acids and esters derived from them have been modified by epoxidation followed by ring opening reaction [3,4,[13][14][15]21] or alternative modification has been carried out by reaction with N-bromosuccinimide and an organic acid. This was already disclosed [4][5][6][22][23][24].…”

(Meth)acrylated methyl oleates substituted with a hydroxy or bromo group were synthesized starting from oleic acid. The latter belongs to materials derived from renewable resources. These new hydroxy or bromo substituted methacrylated methyl oleates possess a higher reactivity compared to lauryl methacrylate in photoinitiated polymerization using Ivocerin® as photoinitiator. Hydroxy acrylated methyl oleate is more efficient in photopolymerization compared to bromo acrylated methyl oleate and lauryl acrylate in the presence of both nitrogen and air.Furthermore, the (meth)acrylated methyl oleates are interesting in applications for coatings because the design of the monomers opens a certain oxygen barrier function.

9,10-epoxyoctadecanoic acid has been detected in human urine. Two simple purification procedures were used; the one based upon liquid-liquid extraction and the other based upon sorbent extraction technology isolating the free fatty acid fraction. Prior to trimethylsilylation and gas chromatographic-mass spectrometric analysis, both the epoxy and carboxy functions were reduced to hydroxy groups. The shift in fragmentation of a deuterated sample verified the presence of intact epoxide prior to chemical reduction. Special attention was paid to the risk of false identification of the epoxide. The content of 9,10-epoxyoctadecanoic acid in human urine was estimated to be 2.1 nM/L.

“…Exactly similar forms of dopa-negative dendritic cells of rhesus rrfonkey were observed. The epidermal digest from Macaca mulatto after demclanization in freshly prepared peracetic acid [Findley et at.. 1945] for 8 h and the epidermal digest from rhesus monkey without demelanization were stained with Mayer's haemalum and examined under the light microscope. A morphological and biometricanalysis of these cells is presented in table I.…”

The digest of the pure epidermis preparation from Macaca mulatta demonstrated three types of dendritic cells i.e. (1) dopa-positive melanocytes, (2) dopa-negative Langerhans’ cells and (3) weakly dopa-positive intermediate cells of Billingham and Medawar. The last type of cell was found to have characteristics being intermediate between those of the melanocytes and of the Langerhans’ cell. A similar digest prepared from the epidermis of the rhesus monkey demonstrated isomorphous dendritic cells which were all dopa-negative. Here also the intermediate cells of Billingham and Medawar with characteristics intermediate between those of the melanocytes and of the Langerhans’ cells were identified.
