The C1-2 complex allows far more motion than any other single level in the cervical spine. This motion is predominantly rotational, since translational motion at C1C2 is limited by the strong transverse ligament. This restriction is lost after fracture of the odontoid and may be associated with anteroor retrolisthesis of the C1-C2 complex in relation to the C2 body. This may result in spinal co...

Our goal was to characterize a phenotypic variation of the pheasant erythrocyte linker histone subtype H1.c. By using two-dimensional polyacrylamide gel electrophoresis three histone H1.c phenotypes were identified. The differently migrating allelic variants H1.c1 and H1.c2 formed either two homozygous phenotypes, c1 and c2, or a single heterozygous phenotype, c1c2. In the pheasant population s...

Structure and excited state isomerisation pathway of retinal in the channelrhodopsin chimera C1C2 have been investigated with combined quantum mechanical/molecular mechanical (QM/MM) techniques, applying CD-MS-CASPT2//CASSCF and DFT-MRCI quantum methods. The absorbing S1 state is of (1)Bu-like character, and the second excited S2 state is dominated by HOMO-LUMO double excitation with small osci...

Within the framework of current phonological theories the typological patterns of regressive place assimilation are treated as the consequence of interactions among constraints that have acoustical and perceptual teleologies. Little is known, however, about the articulatory patterns that underlie the typology of regressive place assimilation. Our current EMA study aims to investigate these patt...

In Russian, the same consonant sequences are permitted in various phonotactic environments. The presence of a word boundary or reduced vowel can be phonologically contrastive, and both learners and experienced listeners may rely on fine acoustic cues to discriminate between phonotactic possibilities. In this study, durational characteristics of consonant sequences are examined to establish whet...
