    MRI-pathological correlations in acute traumatic central cord syndrome: case report (1992)

    Notes: Summary Ante- and post-mortem MRI and detailed pathological examination were performed in a patient with a typical acute traumatic central cord syndrome (ATCCS) after a minor hyperextension injury to the neck who died 60 h later from heart failure. T2-weighted MRI showed a central hyperintense area at C3–4. There were disc protrusions, but no vertebral fracture or displacement. Histopathology disclosed severe axonal swelling and oedema in the dorsolateral fasciculi and, to a lesser degree, in the dorsal columns. In addition, an area of recent necrosis was found in the right anterior horn at C4–5. These findings suggest that the pathological hallmark of typical ATCCS is mechanical axonal disruption at a segmental level, but that more severe trauma may be accompaniedby tissue destruction.

    Notes: Abstract Oxime ether analogs of sex pheromone components of the turnip moth (Agrotis segetum Schiff.) were synthesized by the acidolytic opening of cyclic enol ethers withO-alkyl hydroxylamine hydrochlorides. The compounds varying in chain lengths and in the position of the C=N double bond were studied by electrophysiological single sensillum recordings (electrosen-sillography: ESG). The ESG data indicate in general reduced receptor interaction of all analogs investigated in comparison with natural pheromone components of the turnip moth. The data also show that the grade of decrease of receptor interaction depends on specific structural changes within the molecule. The results demonstrate high complementary pheromone-receptor relationships, predominantly depending on the position of the unsaturated group in the chain, whereas analogs with other structural changes are still recognized as a pheromone-like compound by the receptor.
