The present review discusses the potential use of solid lipid nanoparticles for brain drug targeting purposes. The state of the art on surfactant-coated poly(alkylcyanoacrylate) nanoparticles specifically designed for brain targeting is given by emphasizing the transfer of this technology to solid lipid matrices. The available literature on solid lipid nanoparticles and related carriers for bra...

Structural properties of two model solid Schiff-Mannich bases: 7-[(1-{5-bromo-3[(diethylamino)methyl]-2-hydroxyphenyl}methylidyne)amino]-4-methylcoumarin and N,N -bis{5-bromo-3-[(diethylamino)methyl]salicylidene}-1,2-diaminoethane have been investigated. In both cases a neutral intramolecular O–H...N hydrogen bonding is formed with participation of the Schiff parts of the molecules only. Single...

G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.

Mineral carbon dioxide sequestration binds carbon dioxide by reacting it with magnesium silicate minerals to form solid magnesium carbonates that are ready for disposal. Research onmineral sequestration has focused on enhancing process kinetics in aqueous processing schemes. High costs of these processes are associatedwithmineral processing, such as ultrafine grinding, or the consumption of aci...

The new Schiff bases are synthesis from various and aldehyde and amine under magnetic stirrer method .The synthesized Schiff base were characterized by spectral techniques (UV-Spectra & IR-Spectra). And the Schiff base are yellow colour solid and having sharp melting point and insoluble in organic solvents.

The first stepwise solid-phase synthesis of deoxynucleic guanidine (DNG), a positively charged DNA analog, using controlled pore glass as the solid support is reported. For the first time, purine bases have been incorporated into the DNG oligomer and DNG has been synthesized using a solid-phase method, proceeding in the 3'-->5' direction, that is compatible with the cleavage conditions used in ...

Solid Phase Peptide Synthesis (SPPS) is a key technology for the production of pharmaceutical grade peptides and replacement piperidine with alternative bases piece puzzle moving toward greener technology.
