Glycose 1-phosphate moieties are emerging as important structural units of macromolecular substances imparting special biological functions to these molecules. In the present study, beta-D-glucose 1-phosphate moieties are shown to be structural units and immunological determinants of a bacterial glycan. The glycan is a tetraheteroglycan from the cell wall of Streptococcus faecalis, strain N and...

Ruthenium nanoparticles were prepared by thermolytic reduction of RuCl3 in 1,2-propanediol containing sodium 2-naphthalenecarboxylate. Transmission electron microscopic measurements showed that the average diameter of the resulting 2naphthalenecarboxylate-protected ruthenium nanoparticles (RuCOONA) was 1.30 ± 0.27 nm. Interestingly, hydrothermal treatment of the nanoparticles at controlled temp...

Alzheimer's disease is accompanied by progressive, time-dependent changes of three moieties of amyloid beta. In vitro models therefore should provide same conditions for more physiologic studies. Here we observed changes in the number of fibrils over time and studied the correlation between amyloid beta moieties and neurotoxicity. Although the number of fibrils increased dramatically, the chang...

Electron Beam Lithography is a well-established tool suitable for the modification of substrate surface chemistry. It therefore follows that the deposition and self-assembly of nanoparticles on a surface can be directed using this method. This work explores the effect of electron dose on the electron beam lithographic patterning of selfassembled monolayers (SAMs) on gold surfaces. Electron beam...

A new cyclometalating ligand, featuring nitrile moieties to enhance the photophysical and consequently photocatalytic properties of bis-cyclometalated Ir(iii) complexes, was synthesized. Nitrile moieties were selected to replace expensive and environmentally problematic fluoride moieties commonly employed for synthetic tuning of chromophores. Two new chromophores bearing the new nitrile-decorat...

Using density functional theory based calculations, we have systematically studied the equilibrium geometries, relative stabilities, and electronic and magnetic properties of Fe and Mn atoms interacting with a varying number of BO(2) moieties. These clusters are found to exhibit hyperhalogen behavior with electron affinities as high as 6.9 eV once the number of BO(2) moieties exceed the nominal...

Peptide aptamers are proteins selected from combinatorial libraries that display conformationally constrained variable regions. Peptide aptamers can disrupt specific protein interactions and thus represent a useful method for manipulating protein function in vivo. Here, we describe aptamer derivatives that extend the range of functional manipulations. We isolated an aptamer with increased affin...

We have previously shown that in mice, diphtheria-tetanus-acellular pertussis (DTaP) vaccination before Bordetella pertussis infection resulted in, besides effective clearance, immediate hypersensitivity (lung eosinophilia, increased total serum immunoglobulin E [IgE], and increased ex vivo Th2 cytokine production by cells from the bronchial lymph nodes). To better appreciate the extent of thes...

We designed three experimental 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-based one-step (EX) adhesives consisting of MDP, urethane dimethacrylate, and triethylene glycol dimethacrylate adhesives with different water contents (98.4, 196.8, and 294.4 mg/g), and 4-methacryloyloxyethyl trimellitic anhydride (4-META) or 2-hydroxyethyl methacrylate (HEMA)-containing onestep adhesive. The eff...

An efficient procedure to selectively introduce benzofurazan moieties into peptides was developed. It employs zeolite catalyze the S-conjugation reaction.
