Dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) and Langerin are C-type lectins of dendritic cells (DCs) that share a specificity for mannose and are involved in pathogen recognition. HIV is known to use DC-SIGN on DCs to facilitate transinfection of T-cells. Langerin, on the contrary, contributes to virus elimination; therefore, ...

ABSTRACT: BACKGROUND: A nitrilase-mediated pathway has significant advantages in the production of optically pure (R)-(-)-mandelic acid. However, unwanted byproduct, low enantioselectivity, and specific activity reduce its value in practical applications. An ideal nitrilase that can efficiently hydrolyze mandelonitrile to optically pure (R)-(-)-mandelic acid without the unwanted byproduct is needed. RESULTS: ...

The reaction of 2-cyano-2-methyl propanal with 2'-O-aminooxymethylribonucleosides leads to stable and yet reversible 2'-O-(2-cyano-2,2-dimethylethanimine-N-oxymethyl)ribonucleosides. Following N-protection of the nucleobases, 5'-dimethoxytritylation and 3'-phosphitylation, the resulting 2'-protected ribonucleoside phosphoramidite monomers are employed in the solid-phase synthesis of three chimeric RNA sequences, each differing in their ratios of purine/pyrimidine. When the activation of ...

Organoclays are highly sorptive engineered materials that can be used as amendments in barrier systems or geosynthetic liners. The performance of confining and isolating the non-polar organic contaminants by those barrier/lining systems is essentially controlled by the process of organic contaminant mass transport in nano-pore of organoclays. In this paper, ...
