A multi-site speciation model facilitates double-histidine motif labelling efficiency optimisation for pulse dipolar EPR measurements. Results suggest affinities differing by a factor of 10 between an ?-helical and ?-sheet motif.

microorganisms are important components of soil. some soil filamentous fungi such aspenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. in this study, the metabolites of threepenicillium species (p. goditanum, p. moldavicum and p. corylophilum) were extracted byadding ethyl acetate to liquid cultures. the ...

For thirty years it has been known that certain compositions of Na 2 O-CaO-P 2 O 5 -SiO 2 glasses will form a mechanically strong, chemical bond to bone. These materials have become known as bioactive glasses and the process of bonding is called bioactive fixation. Bioactive glasses are widely used clinically in the repair of bone defects. Recent research at the Imperial College Tissue Engineer...

The combinatorial explosion of motif patterns occurring in 1D and 2D arrays leads to the consideration of special classes of motifs growing linearly with the size of the input array. Such motifs, called irredundant motifs, are able to succinctly represent all of the other motifs occurring in the same array within reasonable time and space bounds. In previous work irredundant motifs were extract...

Background and Aim: This study aimed to compare the sorption and solubility properties of ACTIVA BioACTIVE liner and resin modified glass ionomer (RMGI).   Materials and Methods: In this in vitro study, a total of 30 samples were fabricated from each liner measuring 15 mm in diameter and 1 mm in thickness according to ISO 2009:4049. They were then divided into 6 subgroups (n=5) to assess th...

Over the last several years the search for functional genomic elements by exploiting motif over-representation became increasingly popular. However, about half of the human genome is repetitive, and that is also the case with most higher eukaryotes. In this study we have shown that in addition to these known repeats, human sequences feature many short over-represented motifs, and that their fre...

BACKGROUND The use of different bioactive materials as coating on dental implant to restore tooth function is a growing trend in modern Dentistry. In the present study, hydroxyapatite and the bioactive glass-coated implants were evaluated for their behavior in osseous tissue following implantation in 14 patients. MATERIALS AND METHODS Bioactive glass and hydroxyapatite formulated and prepared...
