    C2 rotation and spinous process deviation in migraine: cause or effect or coincidence? (1991)
    Springer
    Neuroradiology 33 (1991), S. 475-477

    Notes: Summary Previous reports have shown an association between the side of C2 spinous process deviation or asymmetrical prominence, or vertebral rotation, and the side of the headache in unilateral migraine. However, this study has found that such C2 appearances were present as frequently in the controls as in the migraine patients, and that there was no association between the side of the anomaly and the lateralisation of the headache. The results were comparable for the different sub-groups of migraine.

    Notes: Abstract Behavioral studies using an olfactometer demonstrated that spring migrants of the damson-hop aphid,Phorodon humuli, respond to semiochemicals released by spring migrants feeding on hop leaves. Samples of the total volatiles released on feeding were analyzed by coupled gas chromatographysingle cell recording techniques and showed the presence of several active components. Three compounds were identified, using coupled gas chromatography-mass spectrometry, as methyl salicylate, (E)-2-hexenal andβ-caryophyllene. These three compounds elicited responses from separate olfactory receptors on the antenna. In the olfactometer, both (E)-2-hexenal andβ-caryophyllene gave positive responses from spring migrants, and a mixture of the two compounds in the natural ratio was more attractive than (E)-2-hexenal alone. Addition of methyl salicylate eliminated the response to the active binary mixture.
