Two radioaerosol preparations, TechneScan -DTPA (99mTc-DTPA, 40 mCi/3 ml; IPEN-CNEN, São Paulo, SP, Brazil) and TechneScan -DTPA/AEROSOL (99mTc-DTPA/A, 15 mCi/1.5 ml with 0.5 ml ethanol; Mallinckrodt Medical, St. Louis, MO, USA), were compared in pulmonary ventilation studies in terms of total radiocounts and clearance after inhalation. An aerosol with ethanol is supposed to better distribute t...
The diagnostic value of gadolinium-DTPA (diethylenetriamine penta-acetic acid) enhanced magnetic resonance imaging in patients treated by thrombolysis for acute myocardial infarction was assessed in 27 consecutive patients who had a first acute myocardial infarction (14 anterior, 13 inferior) and who underwent thrombolytic treatment and coronary arteriography within 4 hours of the onset of symp...
In the present study shacking and incubation experiments were carried out in order to evaluate the changes in heavy metal solubility in the studied soils by addition of different concentration of Ethylene dinitrilo tetra acetic acid (EDTA), Diethylene triamine penta acetic acid (DTPA), and Nitrilo tri acetic acid (NTA). The effects of EDTA, DTPA and NTA application on solubility of Copper (Cu),...
Introduction: Isonicotinic acid hydrazide (INH) was coupled to diethylenetriaminepentaacetic acid (DTPA) via amide linkage. Primary object of the present invention was to propose a novel INH derivative based on DTPA, which form stable complexes with most of lanthanides and transition metals in periodic table. Another object of the present invention was to introduce a chelating group in INH with...
UNLABELLED Our goal was to determine whether scintigraphy with 111In-DTPA-paclitaxel could predict the response to chemotherapy with paclitaxel. METHODS Ovarian carcinoma (OCA 1), mammary carcinoma (MCA-4), fibrosarcoma (FSA) and squamous cell carcinoma (SCC VII) were inoculated into the thighs of female C3Hf/Kam mice. Mice bearing 8 mm tumors were treated with paclitaxel (40 mg/kg). The grow...
This study was planned to estimate the performance of three zinc fertilizers [Zn sulfate heptahydrate (non-chelated), Zn- EDTA and Zn-humate (chelated)] at four levels (0, 2.5, 5.0, 7.5 mg kg-1) on use efficiency, availability crop productivity with rice. Field trials were conducted in clay loam sandy textured soils using factorial randomized block design (FRBD) replications. Data recorded yiel...
BACKGROUND Because ischemically injured myocardium is frequently composed of viable and nonviable portions, a method to discriminate the two is useful for clinical management. METHODS AND RESULTS Ischemically injured myocardium was characterized with extracellular nonspecific (Gd-DTPA) and necrosis-specific (mesoporphyrin) MR contrast media in rats. Relaxation rates (R1) were measured on day ...
PURPOSE Monoclonal antibodies and tyrosine kinase inhibitors specific for the epidermal growth factor receptor (EGFR) have been shown to enhance the effect of external beam radiation on EGFR-positive tumors. The effect of EGFR signaling abrogation by EGFR tyrosine kinase inhibitor on the efficacy of radioimmunotherapy has not been reported previously. This study investigated the effect of EGFR ...
UNLABELLED We report here the results of studies on the in vitro receptor binding affinity, in vivo tumor uptake and biodistribution of two 99m-Tc-labeled peptides. METHODS Peptides P587 and P829 were synthesized by N-alpha-Fmoc peptide chemistry, purified by reversed-phase HPLC and characterized by fast-atom bombardment mass spectrometry. The peptides were labeled with 99mTc by ligand exchan...
