AbstractFor Dmitri Shostakovich, reaching the heights of the Soviet musical establishment proved easier than staying there. He triumphed with his Fifth Symphony of 1937, which marked the composer's return to official favour after the denunciation of his second opera and third ballet. Following that success, Shostakovich faced the problem of the sequel: whether or not, in the Sixth Symphony, to repeat, refute, or re-inscribe. I propose Shostakovich first thought about going big with his new project, composing a grand text-based score about Lenin, and then considered going small, grounding the first movement in folk fare and mixing light genres in the others. But in the end, he chose a more experimental approach. The Sixth Symphony collapses boundaries, both semantic and syntactic, pulling them back from a fixed state into a play of possibilities.

Resolution Level

The use of thick specimens (0.5 μm to 5.0 μm or more) is one of the most resourceful applications of high-voltage electron microscopy in biological research. However, the energy loss experienced by the electron beam in the specimen results in chromatic aberration and thus in a deterioration of the effective resolving power. This sets a limit to the maximum usable specimen thickness when investigating structures requiring a certain resolution level.An experimental approach is here described in which the deterioration of the resolving power as a function of specimen thickness is determined. In a manner similar to the Rayleigh criterion in which two image points are considered resolved at the resolution limit when their profiles overlap such that the minimum of one coincides with the maximum of the other, the resolution attainable in thick sections can be measured by the distance from minimum to maximum (or, equivalently, from 10% to 90% maximum) of the broadened profile of a well-defined step-like object placed on the specimen.

Abstract: Neuroplasticity research in connection with mental disorders has recently bridged the gap between basic neurobiology and applied neuropsychology. A non-invasive method in the gerbil (Meriones unguiculus) - the restricted versus enriched breading and the systemically applied single methamphetamine dose - offers an experimental approach to investigate psychoses. Acts of intervening affirm an activity dependent malfunctional reorganization in the prefrontal cortex and in the hippocampal dentate gyrus and reveal the dopamine position as being critical for the disruption of interactions between the areas concerned. From the extent of plasticity effects the probability and risk of psycho-cognitive development may be derived. Advance may be expected from insights into regulatory mechanisms of neurogenesis in the hippocampal dentate gyrus which is obviously to meet the necessary requirements to promote psycho-cognitive functions/malfunctions via the limbo-prefrontal circuit.

Inhibition Of Thrombin

SummaryThe extent of inhibition of thrombin was re-examined as a consequence of the sequence of addition of thrombin and antithrombin III to a column of heparin immobilized on agarose. With the use of pure enzyme, pure inhibitor, and a highly sensitive chromogenic substrate, no appreciable difference in the extent of thrombin inhibition was observed between the two sequences of addition. These observations, together with a demonstrated sensitivity of the method to variations in experimental protocol, challenge the conclusions reached in an earlier work (Hatton and Regoeczi, Thromb. Res. 1977; 10:645) which utilized this experimental approach but which employed larger quantities of reactants and a less sensitive substrate.
