Lingitudinal

The (15)N relaxation rates of the α-aminoisobutyric acid (Aib)-rich peptide alamethicin dissolved in methanol at 27°C and 5°C, and dissolved in aqueous sodium dodecylsulfate (SDS) at 27°C, were measured using inverse-detected one-and two-dimensional (1)H-(15)N NMR spectroscopy. Measurements of (15)N longitudinal (R(N)(N(z))) and transverse (R(N)(N(x,y))) relaxation rates and the {(1)H} (15)N nuclear Overhauser enhancement (NOE) at 11.7 Tesla were used to calculate (quasi-) spectral density values at 0, 50, and 450 MHz for the peptide in methanol and in SDS...

Twenty-five microvascular end-in-end and 21 end-to-end anastomoses were performed on the central arteries (diameters 0.8 to 1.2 mm) of rabbit ears. The appearance of longitudinal specimens taken after intervals of 1 to 2 hours and 1, 3, 7, 14, 30, and 90 days was studied microscopically. Between 1 to 2 hours and 14 days, all end-in-end anastamoses showed considerable narrowing of the telescoped segment, and platelets had accumulated at the sleeved vessel end. The vascular walls of the telescoped segment were thickened distally, and the internal elastic laminas were folded in the lingitudinal direction due to contraction...

There is a great difference in the internal fixation of infant and adult fractures. Biological and anatomical pecularities in childhood make it possible for lingitudinal growth to be impaired by the implanted material, its size, its topographic relationship to the growth organ and the duration of implantation. Internal fixation in children should therefore be limited to a few cases and should not be undertaken. Without excellent operative techniques and special aseptic operating rooms. Various ASIF techniques, such as Kirschner wiring, screwing, and fixation with plates, are suitable...

The fine structure of mitochondria and mitochondrial nucleoids in exponentially growing Physarum polycephalum was studied at various periods throughout the mitochondrial division cycle by light and electron microscopy. The mitochondrial nucleoid elongates lingitudinally while the mitochondrion increases in size. When the nucleoid reaches a length of approximately 1.5 mum the mitochondrial membrane invaginates at the center of the mitochondrion and separates the mitochondrial contents. However, the nucleoid does not divide even when the mitochondrial sections are connected by a very narrow bridge...
