Abstract: The present invention provides an optical device for a visually-impaired individual and a method of operating such a device. In one embodiment, the apparatus comprises a spaced array of discrete light sources and a support arranged to maintain the array in proximate relation to at least one eye of the visually-impaired individual. An image capture device is configured to capture images of at least part of the individual's immediate environment, wherein the array is configured to convey information to the individual by selectively illuminating one or more of the discrete light sources based on the content of the captured images. In this way, information relating to objects and/or textual language in the individual's environment can be conveyed to the individual by predetermined patterns of illumination (e.g. spatial and/or temporal). The apparatus and method are found to be particularly suited for visually-impaired individuals who retain at least some residual light and/or colour discrimination.

Abstract: Sulfur-containing compounds, including specifically thiophenic compounds, in a liquid hydrocarbon feedstream are catalytically oxidized by combining the hydrocarbon feedstream with a catalytic reaction mixture that includes a peroxide that is soluble in water or in a polar organic acid, at least one carboxylic acid, and a catalyst that is a transition metal salt selected from the group consisting of (NH4)2WO4, (NH4)6W12O40.H2O, Na2WO4, Li2WO4, K2WO4, MgWO4, (NH4)2MoO4, (NH4)6Mo7O24.4H2O, MnO0 and NaVO3; the mixture is vigorously agitated for a time that is sufficient to oxidize the sulfur-containing compounds to form sulfoxides and sulfones; the reaction mixture is allowed to stand and separate into a lower aqueous layer containing the catalyst and an upper hydrocarbon layer that is recovered and from which the oxidized sulfur compounds are removed, as by solvent extraction, distillation or selective adsorption.

Abstract: Provided are methods of treating or preventing viral infections caused by or associated with a Dengue virus using iminosugars.

Abstract: The process provided herein is concerned with recovery of hydrocarbons from sulfones using an individual alkali and alkaline-earthy base and a mixture of thereof. As the starting materials are sulfones generated by ODS and commercially inexpensive alkali and alkaline-earth bases, the cost and ecological impact of solid waste disposal is minimized.

Abstract: One can treat a viral infection by first administering at least one first antiviral compound for a first time period and then, after the end of the first time period, concurrently or subsequently administering the at least one first antiviral compound and at least one second antiviral compound for a second period. In some cases, after the end of the second period, the same at least one second antiviral compound that was administered during the second time period may be administered for a third time period without concurrent or subsequent administration of the at least one first antiviral compound.

Abstract: The present invention relates to a lipopolysaccharide moiety comprising a conserved triheptosyl inner-core moiety of lipopolysaccharide substantially free of variable outer core oligosaccharide chain extension, and to vaccines obtaines therefrom which are cross-reactive for Haemophilus influenzae strains. The invention also relates to defined mutations in the biosynthetic machinery for lipopolysaccharide (LPS;) expression in Haemophilus influenzae useful to obtain the abovementioned moiety. The invention also relates to using conjugates of the LPS from the mutant strains so obtained to elicit a heterologous immune response against a wide range of disease-causing H. influenzae strains. More specifically, the invention relates to vaccines for prevention of bacterial infections comprising core lipopolysaccharide of Haemophilus influenzae.
