We performed analytical validation of 3 automated assays of the total antioxidant capacity (TAC) in canine serum and evaluated their use in dogs with inflammatory bowel disease. The assays were based on the generation of a 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) radical cation (ABTS•(+)) in aqueous media, which produces a blue-green color. The antioxidants present in the sample remove the chromogen in proportion to their concentrations. The assays differed mainly in the way in which this radical was produced...

OBJECTIVE: A low antioxidants status has been shown to result in oxidative stress and cognitive impairment. Because antioxidants can protect the nervous system, it is expected that a better blood antioxidant status might be related to sustained attention. However, the relationship between the blood antioxidant status and visual and auditory sustained attention has not been investigated. The aim of this study was to evaluate the association of fruits and vegetables intake and the blood antioxidant status with visual and auditory sustained attention in women...

Regulation of intracellular potassium (K(+) ) concentration plays a key role in metabolic processes. So far, only a few intracellular K(+) sensors have been developed. The highly selective fluorescent K(+) sensor KS6 for monitoring K(+) ion dynamics in mitochondria was produced by coupling triphenylphosphonium, borondipyrromethene (BODIPY), and triazacryptand (TAC). KS6 shows a good response to K(+) in the range 30-500 mM, a large dynamic range (Fmax /F0 ≈130), high brightness (ϕf =14.4 % at 150 mM of K(+) ), and insensitivity to both pH in the range 5...

K-Ras is a monomeric GTPase that controls cellular and tissue homeostasis. Prior studies demonstrated that mutationally activated K-Ras (K-Ras(G12D)) signals through MEK to promote expansion and hyperproliferation of the highly mitotically active transit-amplifying cells (TACs) in the intestinal crypt. Its effect on normally quiescent stem cells was unknown, however. Here, we have used an H2B-Egfp transgenic system to demonstrate that K-Ras(G12D) accelerates the proliferative kinetics of quiescent intestinal stem cells...

The presence of a bacterial backbone in conventional eukaryotic expression plasmids may cause undesirable effects by triggering the immune responses in mammals and repression of episomal transgene expression. To avoid these problems, researchers have proposed the use of minicircle DNAs which are episomal vectors that have lost their bacterial backbone using a site-specific recombinase mediated recombination. In the present study, we have constructed a new minicircle DNA vector that carries an enhanced green florescent protein (EGFP) reporter gene using phage ΦC31 integrase-mediated recombination and homing endonuclease ISceI-mediated purification in E...

microRNAs (miRNAs or miRs) are essential in cardiac hypertrophy and in the development of heart failure. In the present study, we aimed to determine whether the restoration of miRNA-455 (miR-455) gene expression in vivo aggravates hypertrophy, but protects against adverse cardiac remodeling induced by pressure overload. Cardiac hypertrophy was induced by left ventricular pressure overload in male mice subjected to transverse aortic constriction (TAC). The mice were randomly selected to receive a tail vein injection of either miR-455 or green fluorescent protein per animal at 1, 8, 15 and 21 days following surgery...
