A bifunctional europium complex of Eu(TTA)(3)(5-NH(2)-phen) using 2-thenoyltrifluoroacetonate (TTA) and 5-amino-1,10-phenanthroline (5-NH(2)-phen) as ligand reagents was applied in DNA detection assays for the first time. The complex has a long fluorescence lifetime, high fluorescence quantum yield, and is easy to label oligonucleotides for time-resolved fluorescence bioanalysis. A two-probe ta...

The present study aimed to investigate the factors affecting the first therapeutic-target-achieving (TTA) time of warfarin therapy in patients with acute pulmonary embolism (PTE). Between January 2008 and June 2013, patients with PTE confirmed by transpulmonary arterial enhanced computed tomographic pulmonary angiography or pulmonary ventilation perfusion scanning were included in the present s...

The motor neuron-like cell line NSC-34 has become a widely used in vitro model for motor neuron biology and pathology. We established a tetracycline-regulated gene expression system in this cell line by stably transfecting pTet-Off, which codifies for the tetracycline transactivator, the regulatory protein tTA. The monoclonal cell lines (NSC-34-tTA) were evaluated for the presence of functional...

High quality digital video transmission requires efficient and reliable data communication over broadcasting channels as there is a risk of data corruption associated during transmission. The near channel performance of Low Density Parity Check Codes (LDPC) has motivated its use in second generation Digital Video Broadcasting (DVB) standards for mobile, cable, satellite and terrestrial channels...

Objectives Biofilm infections of intravascular catheters caused by Staphylococcus aureus may be treated with catheter lock solutions (CLSs). Here we investigated the antibacterial activity, cytotoxicity and CLS potential of 5-hydroxyethyl-3-tetradecanoyltetramic acid (5HE-C14-TMA) compared with the related compounds 3-tetradecanoyltetronic (C14-TOA) and 3-tetradecanoylthiotetronic (C14-TTA), wh...

Most trans-tibial amputation (TTA) patients use a prosthesis to retain upright mobility capabilities. Unfortunately, interaction between the residual limb and the prosthetic socket causes elevated internal strains and stresses in the muscle and fat tissues in the residual limb, which may lead to deep tissue injury (DTI) and other complications. Presently, there is paucity of information on the ...

The hypolipidemic effect of peroxisome proliferator-activated receptor (PPAR) activators has been explained by increasing mitochondrial fatty acid oxidation, as observed in livers of rats treated with the pan-PPAR activator tetradecylthioacetic acid (TTA). PPAR-activation does, however, not fully explain the metabolic adaptations observed in hepatocytes after treatment with TTA. We therefore ch...

We report the NMR solution structure of the intramolecular G-quadruplex formed in human telomeric DNA in K(+). The hybrid-type telomeric G-quadruplex consists of three G-tetrads linked with mixed parallel-antiparallel G-strands, with the bottom two G-tetrads having the same G-arrangement (anti:anti:syn:anti) and the top G-tetrad having the reversed G-arrangement (syn:syn:anti:syn). The three TT...

In Streptomyces coelicolor A3(2) and the related species Streptomyces lividans 66, aerial mycelium formation and antibiotic production are blocked by mutations in bldA, which specifies a tRNA(Leu)-like gene product which would recognize the UUA codon. Here we show that phenotypic expression of three disparate genes (carB, lacZ, and ampC) containing TTA codons depends strongly on bldA. Site-dire...
