Hormones, Lipoproteins and Atherosclerosis, Volume 35, emerged from the international symposium on ""Hormones, Lipoproteins and Atherosclerosis"" held in Bratislava, Czechoslovakia. The symposium was devoted to the problems of hormonal effects on lipoprotein metabolism and atherosclerosis, and was also concerned with problems of composition, structure, synthesis, and degradation of liporoteins, as well as with genetical and clinical aspects. The participants of the symposium have contributed to this volume not only by presenting new data but also new ideas and stimulating new trends in the research and therapy of metabolic derangements of lipoproteins and the resulting pathological conditions. The 51 contributions are organized into five parts. Part I includes papers on the metabolism of lipoproteins. Part II presents studies on hormones and lipoproteins. Part III is devoted to atherosclerosis and lipoproteins. Part IV takes up the clinical aspects of hyperlipoproteinemias. Part V on methods contains two studies—the first on the isolation of human plasma high density lipoproteins; the second on the separation of subfractions of the serum triacylglycerols.
