Abstract:
The invention is concerned with the use of certain fatty acids and inhibitors of an enzyme in effecting modifications to the lipid structure of cell membranes and in modifying the degree of expression of cell receptors and antigen determinants. The invention also relates to the formulation of pharmaceutical compositions and medicaments and to such products per se; to the treatment of a variety of clinical and veterinary disorders associated with a lowering of the saturation index of cell membranes, including malignancies, viral disorders and AIDS; and to the use of the active materials of the invention in the relief of pain and in bioengineering processes. The active principals in the present invention are saturated fatty acids having from 12 to 28 carbon atoms in the alkyl chain, e.g. stearic acid, or pharmaceutically acceptable derivatives thereof; and inhibitors of the enzyme A-9 desaturase, e.g. sterculic acid and malvalic acid or pharmacologically active derivatives or analogues thereof. Interferon is also used in modifying the expression of cell receptors and antigenic determinants.

Abstract:
A method of modifying the lipid structure of cell membranes is disclosed which utilises the supernatant derived from a culture of Micrococcus cryophilus (ATCC 15174) or an extract therefrom. This method has utility in veterinary and clinical treatment of conditions characterised by an increase in the saturation index. Compositions incorporating the active ingredient are also provided.
Abstract:
Utilisation de certains acides gras pour produire des modifications de la structure lipidique des membranes cellulaires. L'invention se rapporte également à la formulation de compositions pharmaceutiques et de médicaments et à ses produits en soi; au traitement d'un ensemble de troubles cliniques et vétérinaires associés à l'élévation de l'indice de saturation des membranes cellulaires, notamment de troubles nerveux comprenant la sclérose en plaques et la schizophrénie; ainsi qu'à l'utilisation des substances actives faisant l'objet de l'invention dans le traitement desdits troubles. Les principes actifs décrits sont des acides gras mono-insaturés présentant de 12 à 28 atomes de carbone dans la chaîne alkyle, par exemple l'acide oléique, ou des dérivés pharmaceutiquement acceptables.
Abstract:
Hypomethylation of the L1 retrotransposon sequence is demonstrated in cancerous cells. The invention provides the use of a retrotransposon, in particular the L1 sequence, as a promoter to control gene expression in a method of gene therapy.
Abstract:
Methods of and devices for monitoring the treatment of a human or non-human animal are disclosed. These involve a sensor which is adapted (a) to receive and to rectify an electromagnetic (e.g. radio) signal directed from outside the body towards it, and (b) to transmit data relating to treatment parameters by wireless telemetry to a receiver external to the body of the human or non-human animal. The data transmitted by the sensor is then processed to provide information on the treatment.
Abstract:
Use of certain fatty acids in effecting modifications to the lipid structure of cell membranes. The invention also relates to the formulation of pharmaceutical compositions and medicaments and to such products per se; to the treatment of a variety of clinical and veterinary disorders associated with elevation of the saturation index of cell membranes, including nervous disorders including multiple sclerosis and schizophrenia; and to the use of the active materials of the invention in the treatment thereof. The active principles in the present invention are mono-unsaturated fatty acids having from 12 to 28 carbon atoms in the alkyl chain, e.g. oleic acid, or pharmaceutically acceptable derivatives thereof.
Abstract:
Devices suitable for insertion into a hollow anatomical structure within a patient for the purpose of ablating tissue within or surrounding the hollow structure so as to induce occlusion of the hollow structure are provided. The devices are in the form of guidewires with functional tips, that comprise at least one heating module, at their distal ends. The devices of the invention are suitable for occluding hollow anatomical structures selected from vasculature or from non-vascular ducts and tubes, via percutaneous, laparoscopic or endoscopic routes of access. Methods of using the devices in the treatment of patients are also described.
Abstract:
A flexible RF device (1) can be deployed through a flexible endoscope. An electrode structure has a central electrode (12) and outer electrode (11). Flexible electrodes (30), circular electrodes (51, 53) and circular loop assemblies (55, 56) with different diameters are also disclosed, as well a tweezer electrodes (41) with pads (43) for increasing contact area. Retractable electrodes (100) are also disclosed.
Abstract:
A method for using thiazine dyes, especially methylene blue, alone or in combination with low levels of light, to treat parasitic diseases is described. Examples of useful thiazine dyes are methylene blue, azure A, azure C, toluidine, and thionine. The preferred dye is methylene blue, administered orally twice a day. Since methylene blue absorbs in the red wavelengths, i.e., approximately 670 nm, which penetrates tissue much better than other lower wavelengths, light penetrating the skin to the capillaries at the surface can be used to enhance the activity of the dye. The thiazine dye can be provided in combination with other known antibiotics, anti-inflammatories, anti-parasitics, antifungals, and antivirals.
