 Title    O n the Cross-Section Structure of the Mitochondrial Cristae-Membrane as Revealed by X-Ray Diffraction  
 Abstract    Mitochondria were isolated using sorbitol and high buffer concentration in the medium. X-ray diffraction patterns arising from the mitochondrial cristae-membrane were recorded in the fully dried state and in two different states in humidity. The (Munction evaluation of these X-ray dif­ fraction diagrams resulted in electron density cross-section profiles, which consist of two main peaks of opposite sign and one, respectively two, brane amounts to 120 Ä in the dry and 140 Ä to cross-section profile is tentatively proposed.

 Title    Determination of the Electron Density Profile of the Nerve Myelin Membrane in Different States Taking Paracrystalline Lattice Distortions into Account  
 Abstract    Recent investigations point to the presence of paracrystalline lattice disorder in the nerve myelin in the swollen, fixed and to some extent also in the native state. This leads to the distortion of the ^-function of the membrane stack and the @0-function of the unit cell, which can be ex­ perimentally isolated through swelling. Representing the distance statistics between neighbouring membranes and the electron density distribution of the single membrane with Gaussian functions, the (^-function can be expressed analytically as a convolution polynomial of the electron density, its mirror image and the distance statistics functions. Fitting this model (^-function to the experimental ^-function obtained by the inverse Fourier transformation of the scattered intensity, one can determine the optimal parameters of the electron density distribution and the distance statistics functions. The elimination of the distance fluctuations between neighbouring membranes permits the calculation of the undistorted 0-function or the ()0-function. The Fourier Analytical Deconvolution of the undistorted £>0-function enables a unique determination of the double membrane profile, thus a unique phase determination.
