Abstract: The instant invention relates to a combination, particularly a synergistic combination, of an alpha-2-delta ligand and an atypical antipsychotic, and pharmaceutically acceptable salts thereof, pharmaceutical compositions thereof and their use in the treatment of pain, particularly neuropathic pain.

Abstract: The instant invention relates to a combination of an alpha-2-delta ligand and an AChE inhibitor for use in therapy, particularly in the treatment of pain, particularly neuropathic pain. Particularly preferred alpha-2-delta ligands are gabapentin and pregabalin. Particularly preferred ACHE inhibitors are donepezil (Aricept®), tacrine (cognex®), rivastigmine (Exelon®), physostgmine (Synapton®), galantamine (Reminyl), metrifonate (Promem), neostigmine (Prostigmin) and icopezil.

Abstract: The instant invention relates to a combination, particularly a synergistic combination, of an alpha-2-delta ligand and a dual serotonin-noradrenaline re-uptake inhibitor (DSNRI) or one or both of a selective serotonin re-uptake inhibitor (SSRI) and a selective noradrenaline re-uptake inhibitor (SNRI), and pharmaceutically acceptable salths thereof, pharmaceutical compositions thereof and their use in the treatment of pain, particularly neuropathic pain.

Abstract: A method of removing from a metal salt ionic species contained therein involves contacting the metal salt with an ionic liquid to dissolve the metal salt, the ionic species or both. At least in the case where both the metal salt and the ionic species are dissolved, the resultant ionic liquid composition is treated to separate the ionic species therefrom and subsequently processed to recover the metal salt.

Abstract: A method of dissolving in an ionic liquid a metal in an initial oxidation state below its maximum oxidation state, characterized in that the ionic liquid reacts with the metal and oxidizes it to a higher oxidation state. The initial metal may be in the form of a compound thereof and may be irradiated nuclear fuel comprising UO2 and/or PuO2 as well as fission products. The ionic liquid typically is nitrate-based, for example a pyridinium or substituted imidazolium nitrate, and contains a Bronstead or Franklin acid to increase the oxidizing power of the nitrate. Suitable acids are HNO3, H2SO4 and [NO+]. Imidazolium nitrates and certain pyridinium nitrates form one aspect of the invention.

Abstract: A method of purifying a UF.sub.6 gas stream which comprises irradiating the UF.sub.6 gas stream with laser radiation in a vessel in order to selectively convert fluoride impurities in the gas stream to involatile products, removing the purified UF.sub.6 gas stream from the vessel and separately removing the impurities from the vessel.
