The present invention relates to cannabidiol derivatives and to pharmaceutical compositions comprising cannabidiol derivatives being antiinflammatory agents having analgesic, antianxiety, anticonvulsive, neuroprotective, antipsychotic and anticancer activity. A first initial message of a handshaking procedure for a first secure communication session between a first device and a second device is intercepted at a proxy device. Mutual separation of the stacked catalyst carriers can be suppressed by the tooth portion of the engaging plate. The assay input layer can comprise an assay input port extending from the first surface to the second surface and at least one pressure nodule extending from the second surface.
