To observe the inhibitory effects of an attenuated S. typhimurium strain carrying IL-2 gene (TPI) on hepatoma cell line (HepG2) and transplanted tumors in mice. TPI, TPG (an attenuated S. typhimurium strain carrying green fluorescent protein gene), and TP (an attenuated S. typhimurium strain) strains were transfected into HepG2 cells. At 48 h after transfecting, the transfection rate was 82.58 ...
Light-mediated hydrolysis of phosphatidylinositol-4,5-bisphosphate (TPI) to 1,2-diacylglycerol and D-myo-inositol 1,4,5-triphosphate (IP3) has been reported in the visual photoreceptor cells. We have investigated the localization of the TPI antigenic sites in dark- and light-adapted rat retinas using rabbit anti TPI antibodies (Ab). Sprague-Dawley rats were dark-, or light-adapted, or were expo...
A striking correlation between neural expression and high net negative charge in some teleost isozymes led to the interesting, yet untested, suggestion that negative charge represents an adaptation (via natural selection) to the neural environment. We examine the evolution of the triosephosphate isomerase (TPI) gene family in fishes for periods of positive selection. Teleost fish express two TP...
We present terahertz pulsed imaging (TPI) as a novel tool to quantify the hardness and surface density distribution of pharmaceutical tablets. Good agreement between the surface refractive index (SRI) measured by TPI and the crushing force measured from diametral compression tests was found using a set of tablets that were compacted at various compression forces. We also found a strong correlat...
Triosephosphate isomerase (EC 5.3.1.1) from Lactococcus lactis was purified to electrophoretic homogeneity. Approximately 3 mg purified enzyme (specific activity 3300 U mg-l) was obtained from 70 g (wet wt) cells. In solution, triosephosphate isomerase (pl4*044) was observed to exist as a homodimer (M, 57000) of noncovalently linked subunits. The sequence of the first 37 amino acid residues fro...
The authors developed two versions of a therapeutic presence measure, based on an earlier model of presence (Geller & Greenberg, 2002)-Therapeutic Presence Inventory-therapist (TPI-T) and client (TPI-C) versions-to measure in-session therapeutic presence. They explored their reliability and validity in two studies. In the first, items generated from the previously established model were subject...
Treponema pallidum-immobilizing (TPI) antibodies were examined in intradermally infected inbred strain 13 and adoptively immune inbred strain 2 guinea pigs. Both strains of animals produced TPI antibodies at or after 90 days of infection. TPI antibodies were not associated with the protective mechanism(s) operative after challenge in adoptively immune animals.
BACKGROUND Clinical practice guidelines recommend objective nutritional assessments in managing chronic kidney disease (CKD) patients but were developed while referencing to a North-American population. Specific recommendations for assessing muscle mass were suggested (mid-arm circumference, MAC; corrected mid-arm muscle area, cAMA; mid-arm muscle circumference, MAMC). This study aimed to asses...
Amyloid-β peptide (Aβ) aggregates induce nitro-oxidative stress, contributing to the characteristic neurodegeneration found in Alzheimer's disease (AD). One of the most strongly nitrotyrosinated proteins in AD is the triosephosphate isomerase (TPI) enzyme which regulates glycolytic flow, and its efficiency decreased when it is nitrotyrosinated. The main aims of this study were to analyze the im...
Tuna processing by-product is estimated at more than 100,000 metric tonnes annually in Iran, which could be a potential source of edible protein in human food. Hence, recovering proteins from tuna by-products is a big achievement in the seafood industry. In this work tuna protein isolates (TPI) were extracted from dark/ red meat using the isoelectric solubilization/ precipitation method. Oxidat...
