The invention provides a remedy for chronic inflammation and an anti-TNIIIA2 antibody to be used therein. The present metamaterials include embedded particles arrays that provide coupled magnetic and electronic modes equivalent to L and C circuit models. Spines are formed from at least a portion of the clusters based on the concepts. The coolant chamber entrance and exit communicate with corresponding coolant inlet and outlet passageways, respectively, cooperatively defined by a pair of insulators which retain the heat sink in a predetermined orientation within an evacuated envelope of an x-ray device. The inner circumference of the boss and a portion of the rigid core member and the outer circumference of the boss and the outer mover-molded portion form a knob-boss interface that sustains impacts to the rotary knob assembly while isolating a rotary switch from impacts.
