摘要:
A fuel oil composition comprising a fuel oil and 0.1 to 10,000 ppm of a polymeric condensation product which is formed by the reaction of an aliphatic aldehyde or ketone, or a reactive equivalent, with either (i) a straight or branched chain C1-C7 alkyl ester of p-hydroxybenzoic acid, or with (ii) a branched chain C8-C16 alkyl ester of p-hydroxybenzoic acid, or with (iii) a mixture of long chain C8-C18 alkyl esters of p-hydroxybenzoic acid, at least one of said alkyls being branched. The polymeric condensation product improves the cold flow characteristics of the fuel oil.
摘要:
The present invention relates to methods for prion decontamination comprising (i) contacting an entity to be decontaminated with a detergent, (ii) contacting said entity with one or more protease(s), and optionally (iii) autoclaving said entity. The invention further relates to kits comprising detergents and proteases for prion decontamination, and compositions comprising detergents and proteases for prion decontamination.
摘要:
The present invention relates to a method of making a β-form of a prion protein which preferably has more β-sheet than α-helix structure and is soluble in the absence of a denaturant and/or is non-aggregated and exhibits partial resistance to digestion with proteinase K. The invention also relates to use of the β-form in medicine, especially for raising to antibodies useful in the treatment and/or diagnosis of prion diseases. The invention also relates to methods of screening for compounds which are capable of inhibiting and/or reversing the conversion of the native α-form of a prion protein to a β-form, and to uses of identified compounds in medicine.
摘要:
The use of an additive composition to improve the conductivity of a fuel oil. The additive composition comprises a polymeric condensation product formed by the reaction of an aliphatic aldehyde or ketone, or a reactive equivalent, with at least one ester of p-hydroxybenzoic acid.
摘要:
The present invention provides for a pharmaceutical composition that includes tetrabenazine and a release-retarding agent; and a method of treating a hyperkinetic movement disorder (e.g., Huntington's disease, chorea associated with Huntington's disease, hemiballismus, senile chorea, tic disorders, tardive dyskinesia, myoclonus, dystonia and/or Tourette's syndrome). The method includes administering an effective amount of the pharmaceutical composition, for a period of time effective to treat the hyperkinetic movement disorder.
摘要:
An additive composition for a fuel oil composition and that is free of polycyclic carboxylic acids and of acid derivatives thereof comprises an additive that comprises one or more monocarboxylic acids, each having from 10 to 24 carbon atoms, or acid derivatives thereof, optionally in combination with one or both of an anti-oxidant additive and an anti-static additive.
