CLASS: IC: C08F002-50. APPLICATION: JP 78-2384 13 Jan 1978. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 56 Photocurable coating compn. contained dialkylamino compds. and nitriles as photoinitiators. Thus, a compn. from pentaerythritol [115-77-5] 50, p-(dimethylamino)chalcone (I) [1030-27-9] 1, p-cyanochalcone (II) [5724-55-0] 1, chlorinated polyethylene 50, and ClCH2CH2Cl 500 parts was coated on Al and dried at 80° for 10 min to give a coating with photosensitivity (0-15 photog. wedge scale) 9-10, compared with 5 for a control not contg. II and 0 for a control not contg. I.

CODEN: BIMEE9. ISSN: 0233-4755. DOCUMENT TYPE: Journal CA Section: 13 (Mammalian Biochemistry) Section cross-reference(s): 9 The spacial structure of lipids in living human lymphocytes and granulocytes has been studied using the energy transfer between lipophilic fluorescent probes. One of the probes, energy donor (DMC), was localized in the lipid interior, whereas another donor (K-68) and energy acceptor (DSP-12) were near the lipid/water interface. The energy transfer in lymphocytes was the same as in artificial lipid membranes (liposomes). Obviously, in lymphocytes, as well as in liposomes, both donors are localized near the lipid surface (the distance from the donors to lipid surface is less than Forster's radium RO, i.e. 3,4-5 nm). On the contrary, in granulocytes, the energy transfer from K-68 was 2.2 times more efficient than the lipid-immersed DMC. It was suggested that a fraction of DMC mols. was immersed into some lipid particles, and the distance from the mols. to particle surface was greater than RO. The positions of the DMC fluorescence spectrum maxima in lymphocytes and in liposomes were the same, but in granulocytes, the spectrum was blue-shifted (as in the case of lipoproteins). After subcellular fractionation the DMC fluorescence intensity correlated only with the phospholipid concn. in different fractions but not with the protein or nucleic acid concns. It was suggested that lipid organelles are the main source of the DMC fluorescence. The studies of cell-lipoprotein model mixts. supports the suggestion that lipids in lymphocytes are mainly presented as lamellar structures (membranes); the presence of lipoprotein-like particles of rather small radius can not be excluded too. On the other hand, in addn. to membrane lipids, granulocytes have got lipid-contg. particles like large serum very low d. lipoproteins. .
