| 20100324107 | USE OF PHTHALIMIDE AND/OR SULPHONAMIDE DERIVATIVES IN THE TREATMENT OF DISEASES WHICH REQUIRE REDUCING THE TNF-alpha LEVELS AND AN EXOGENOUS SOURCE OF NITRIC OXIDE, PHTHALIMIDE DERIVATIVES, SULPHONAMIDE DERIVATIVES, AND A METHOD FOR OBTAINING A SULPHONAMIDE DERIVATIVE - The present invention refers to the use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, which have important activities in increasing the gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-α levels and an exogenous source of nitric oxide. More particularly, the present invention describes the use of such phthalimide and/or sulphonamide derivatives for the treatment of sickle-cell disease. The invention also has as a novel characteristic the disclosure of new functionalized phthalimide derivatives designed from the prototypes thalidomide and hydroxyurea, and designed rationally through the strategy of molecular hybridization for the treatment of said diseases. The invention still discloses a new method for obtaining a specific sulphonamide derivative which can be used in the preparation of a drug for the treatment of diseases which require reducing the levels of the TNF-α factor and an exogenous source of nitric oxide. | 12-23-2010 |
| 20100208243 | OPTICAL SENSING SYSTEM FOR LIQUID FUELS - The present invention relates to a thermally compensated optical sensing system for identifying various types of liquid fuels and/or the ratio in liquid fuel mixtures on real time. In this system, an optical fiber is used as a light guide and a sensor device for determining the refractive index of liquid fuels through the principle of reflectivity. Starting from a light source, light is transmitted interiorly of the optical fiber to the test probe which is in contact with the fuel. The optical signal resulting from the interaction between light and fuel is a function of refractive indexes of the optical fiber and the fuel, the wavelength of light used, and the fuel temperature. The system proposed herein relates to the use of this optical system in liquid fuels by using optical fibers having suitable refractive indexes as a function of the fuel type and/or fuel mixture being analyzed, allowing the sensitivity of the optical system to be optimized according to application requirements. | 08-19-2010 |
| 20100112033 | STENTS COATED WITH NO- AND S-NITROSOTHIOL-ELUTING HYDROPHLIC POLYMERIC BLENDS - This invention relates to stents coated with hydrophilic polymers containing S-nitrosothiols, which are able to provide local delivery of both nitric oxide and S-nitrosothiols by diffusion. This device is intended for coronary angioplasty applications with the purpose of inhibiting acute and chronic restenosis and refers to processes of stent coating with hydrophilic polymers containing incorporated S-nitrosothiols. This invention refers to an intracoronary implant device used in medical procedures, and introduces new S nitrosothiol-eluting stents coated with hydrophilic polymer multilayers. The hydrophilic polymers used for coating are polyvinyl alcohol, polyvinylpirrolidone and polyvinyl alcohol/polyvinylpirrolidone, polyvinyl alcohol/polyethylene glycol, polyvinylpirrolidone/polyethylene glycol and polyvinyl alcohol/polyvinylpirrolidone/polyethylene glycol blends. The S-nitrosothiols incorporated to the polymer coatings are mainly primary S-nitrosothiols, characterized by the fact of the nitric oxide (NO) molecule being covalently bound to a sulfur (S) atom which, in turn, is linked to a primary carbon in the molecule's structure, thus constituting the S—NO chemical group. The coating processes include immersion of the stents in polymer solutions containing S-nitrosothiols and nebulization processes of the polymer solutions containing S-nitrosothiols onto the stent surface. | 05-06-2010 |
