Cytochrome c (cyt c)-immobilized monolayers and multiple monolayers of a conducting polymer [poly(terthiophene-3-carboxylic acid) polymer (poly-TTCA)] were prepared, where the monolayer of monomer precursor was fabricated with the Langmuir-Blogett technique. Covalent immobilization of cyt c was achieved by the formation of an amide bond between the carboxylic groups of the conducting polymer an...

Crystals of adenylate kinase from beef heart mitochondrial matrix (EC 2.7.4.10) complexed with its substrate AMP were analyzed by X-ray diffraction. The crystal structure was solved by multiple isomorphous replacement and solvent flattening at a resolution of 3.0 A. There are two enzyme-substrate molecules in the asymmetric unit. The resolution was extended to 1.9 A by model building and refine...

Modification of deoxyguanosine at the C(8) position by the carcinogen N-acetoxy-N-2-acetylaminofluorene (N-AcO-AAF) has been shown to result in two different conformational changes dependent on the nucleotide sequence of the modified polymer. AAF modification of random sequence DNA results in a large distortion of the helix which is termed base displacement. In this conformation, the carcinogen...

Research suggests that individuals with social anxiety show an attention bias for threat-relevant information However, few studies have directly manipulated attention to examine its effect on anxiety. In the current article, the authors tested the hypothesis that an attention modification program would be effective in reducing anxiety response and improving performance on a public-speaking chal...

Two novel thermo-responsive polymer brushes were prepared from L-alanine derivatives using the surface-initiated atom transfer radical polymerization (SI-ATRP) technique. The temperature-induced cell capture and release on both polymer brush modified substrates were further explored.

Concrete is a building material, which in many cases fulfills the requirements for high sustainability. Industrial by-products, e. g. fly ash or silica fume, are used for improving the fresh and hardened properties of concrete, blast furnace slag for cement production, but also concrete by itself can be used as aggregate to produce strong and durable concretes. In this contribution examples of ...

In this paper, the influence of vacuum infiltration lightweight ceramic aggregates as fillers in polymeric concretes was described. first stage investigation, a set with high open porosity about 27% produced on basis industrial wastes. Ceramic size 2 to 4 mm, hereinafter referred granules, were using contaminated glass cullet waste and coal shale. The effectiveness granule epoxy resin productio...

The use of pozzolanic waste materials as partial cement replacement is customary in contemporary concretes from a sustainability perspective. In this experimental study, the liquid crystal display (LCD) glass was finely ground to be used SCM, and potential beneficial effects terms strength, hydration, durability resulting were evaluated. Concretes with 10% 20% by LCD powder (LCDGP) developed su...
