The capping of the 3'-ends of thrombin binding aptamers (TBAs) with bridged nucleotides increased the nuclease resistances and the stabilities in human serum. The binding abilities of the aptamers were not affected by the capping. The capping could be simply executed via a one step enzymatic process using 2',4'-bridged nucleoside 5'-triphosphate and terminal deoxynucleotidyl transferase.

Lymphocyte capping with antihuman immunoglobulin was studied in 16 cases of myotonic dystrophy, including two cases with the congenital form. Percentage capping after 1 hour incubation was reduced and the time course of the capping sequence was apparently delayed. The significance of these findings remains to be determined.

Nerve capping techniques have been introduced as a promising treatment modality for the treatment of painful neuroma with varied outcomes; however, its exact mechanism is still unknown. RhoA is one of the members of the RAS superfamily of GTPases that operate as molecular switches and plays an important role in peripheral nerve regeneration. Our aim was to investigate the structural and morphol...

We have localized capping protein in epithelial cells of several chicken tissues using affinity-purified polyclonal antibodies and immunofluorescence. Capping protein has a distribution in each tissue coincident with proteins of the cell-cell junctional complex, which includes the zonula adherens, zonula occludens, and desmosome. "En face" views of the epithelial cells showed capping protein di...

Capping agents, key for nanoparticle stability, may hugely influence chemical behaviour. We show that differently capped gold nanoparticles, with either citrate or cetyl trimethylammonium bromide (CTAB) capping agents, show qualitatively different electron transfer properties. Specifically through cyclic voltammetry and nanoimpact studies the CTAB promoted dissolution of gold nanoparticles is s...

RNA polymerase II nascent transcripts are capped during pausing before elongation. Here we report that hSPT5, the human homolog of yeast elongation factor SPT5, interacts directly with the capping enzyme. hSPT5 stimulated capping enzyme guanylylation and mRNA capping by severalfold. Although RNA 5'-triphosphatase activity was unaffected, binding to this domain in the full-length enzyme is likel...

We study the effects of low-temperature capping (200-450°C) on the optical properties of GaAs/AlGaAs quantum wells. Photoluminescence measurements clearly show the formation of abundant nonradiative recombination centers in an AlGaAs capping layer grown at 200°C, while there is a slight degradation of the optical quality in AlGaAs capping layers grown at temperatures above 350°C compared to tha...

Device encapsulation and packaging often constitutes a substantial part of the fabrication cost of micro electro-mechanical systems (MEMS) transducers and imaging sensor devices. In this paper, we propose a simple and cost-effective wafer-level capping method that utilizes a limited number of highly standardized process steps as well as low-cost materials. The proposed capping process is based ...

AIM To evaluate the clinical and radiological response of primary molars to direct pulp capping with calcium sulfate hemihydrate. MATERIALS AND METHODS Forty primary molar teeth in 40 healthy children aged 5-9 years were treated by direct pulp capping. Teeth were randomly assigned to two groups (n=20) according to material used for capping, as follows: Group 1: calcium hydroxide cement (Dycal...

Introduction: The main aim during any dental treatment is to maintain vital pulp as long as possible. Objective: The aim of this study was to assess clinically the use of MTA in direct pulp capping in adult patient. Method: MTA was performed in two visits treatment protocol on direct pulp capping in adult. Results: Clinical and radiological examination conducted after 7 months post treatment of...
