Small-angle x-ray scattering study of human serum low-density lipoproteins with differential reactivity for an arterial proteoglycan.

The structure and thermal behavior of human serum low-density lipoproteins showing either a high or a low reactivity against a proteoglycan isolated from human arteries have been found to be different from each other. It is suggested that modifications in the lipoprotein surface structure induced by the physical state of the neutral lipids could modulate the affinity of the macromolecule for the arterial component.

The alkaline hydrolysis of these vinyl phosphates gives dimethylphosphoric acid and the corresponding N-methylated acetoacetamide which is titrated with sodium nitrite. The polarovoltry (constant current potentiometry) is well appropriate for end point detection. Free acetoacetamides are determined in the same way in non-hydrolized samples and taken into account.     

Ornstein-Zernike and analyticity properties for classical lattice spin systems

The leading Ornstein-Zernike behavior of the truncated two-point function G(x) is obtained from information on the poles of the Fourier transform G~(p). Analyticity of G~(p) as a function of the complex variables p and the inverse temperature β is studied in detail for |β| sufficiently small.
