Mycobacterium ulcerans (MU) infection of skin and soft tissue leads to chronic ulceration known as Buruli ulcer. MU releases a lipid-like toxin, mycolactone, that diffuses into the tissue, effecting disease through localized necrosis immunosuppression. Cutaneous ulcer wounds slowly advance from painless pre-ulcerative stage an ulcerative lesion, leading disparities in timing medical interventio...

While in tropical soils recycling of plant phytoliths has been shown to represent a major pool Si available for plants, the main pools plants temperate are still poorly constrained. We characterised various forested and cultivated France by selecting seven paired sites (adjacent wheat forest plots) four soil groups: Luvisols, Albeluvisols, calcaric hypereutric Cambisols. showed that CaCl2-extra...

This paper examines the mineral and geochemical features of lake sediments waters in intermittent Lake Taloe, located a semiarid climate. Minerals that belong to groups oxides, sulfides, aluminosilicates, carbonates, sulfates, halides are identified through use precision methods. The resulting species divided by genetic into two associations: terrigenous hydrogenic. association includes water-i...

Novel biomaterials for diagnostics and therapeutics of biomedical issues have been considered using science health care. Halloysite nanotubes (HNTs) are naturally occurring aluminosilicate clay. Because their unique hollow tubular structure, biodegradability, mechanical surface properties, they drawn the attention researchers to a variety applications. HNTs inorganic natural aluminosilicates th...

Colloidal porous hosts in the form of microporous aluminosilicate (zeolite) or mesoporous silica nanoparticles are attractive materials for a wide range of potential applications, i.e. controlled release drug delivery systems. However, many fundamental challenges still remain in this relatively young research field. The following work focuses on overcoming some of the present limitations by dev...

Synthetic exchanged zeolites have proved to be active catalysts for the selective catalytic reduction (SCR) NO x by hydrocarbons as reductors in the presence of O 2. The abundance and potentiality of argentine zeolite mineral resources encouraged us to analyze the possibitity of taking advantage of these minerals as starting materials for catalyts preparation. In this sense, clinoptilolite-rich...
