Ammonium Bicarbonate‐DTPA and DTPA Extractions of Sludge‐amended Soils

Journal of Environmental Quality, 1987
AbstractA DTPA (diethylenetriaminepentaacetic acid) solution is typically used to extract sludge‐amended soils to determine the relationship between soil concentration and plant levels of certain trace elements. The objective of this study was to compare the standard DTPA soil test method with the ammonium bicarbonate (NH4HCO3)‐DTPA (AB‐DTPA) procedure

Gd-DTPA

Journal of Computer Assisted Tomography, 1994
The purpose of this study was to demonstrate that gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) could be used as a contrast medium in CT as an alternative to iodine-based compounds.Solutions of different concentrations of Gd-DTPA and iopromide were scanned in a tissue equivalent phantom and it was shown that Gd-DTPA caused 2.5 times the ...

Comparison of Tc99m-DTPA and Indium-111 DTPA Studies of Baclofen Pump Function

Clinical Nuclear Medicine, 2004
An intrathecal drug delivery system is composed of a programmable infusion pump implanted in an abdominal subcutaneous pocket and a connecting catheter, which is inserted in the intrathecal space in the spine, usually in the thoracic or lower cervical region. Intrathecal administration of Baclofen could help reduce limb spasticity, avoiding some of the

Spectrophotometric method for the determination of a bifunctional DTPA ligand in DTPA-monoclonal antibody conjugates

Bioconjugate Chemistry, 1992
A simple spectrophotometric method was developed to quantitate micromolar concentrations of a bifunctional DTPA ligand in DTPA monoclonal antibody (mAb) conjugates. Titration of a brightly colored 1:2 yttrium (III) complex of arsenazo III with the ligand 1B4M-DTPA obeyed Beer's law over the concentration range 0-2.0 microM 1B4M-DTPA at 652 nm.

Gadolinium-DTPA in Spinal Disease

Radiologic Clinics of North America, 1988
The use of paramagnetic contrast agents, in particular, gadolinium-DTPA, holds great promise for the MR evaluation of the spine. However, because of the lack of a previous model for intravenous contrast enhancement in the spine and because of some peculiarities of enhancement of spinal lesions, close attention must be paid to the appropriate uses of ...

Decorporation of 241 Am in Beagles by DTPA

Radiation Research, 1975
Chelation treatments using daily subcutaneous injections of ${\rm ZnNa}_{3}\text{-}{\rm DTPA}$ were begun 2 wk after the intravenous administration of 0.3 μCi/kg241 Am citrate to six female beagles averaging 505 days of age. Retention of americium in the liver and in nonliver tissue (mainly skeleton) was followed serially in the living dogs by a ...

Factors influencing DTPA conjugation with antibodies by cyclic DTPA anhydride.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1984
Diethylenetriaminepentaacetic acid (DTPA) was conjugated with a practical concentration (300 micrograms/ml) of antibody to human albumin (Ab) and 1083 17-1A monoclonal colorectal antibody (MAb-17-1A) via an acylation reaction using cyclic DTPA anhydride (cDTPAA). The conjugation reaction was favored as pH increased.

Environmental Fate of EDTA and DTPA

1997
EDTA can be extremely persistent in WWTP and also in natural waters; DTPA seems more biodegradable. However, the biodegradability of DTPA might be of negligible significance as EDTA, and in some cases also DTPA, are generally found in the receiving waters of many industrial areas, thus being classified as one of the major organic pollutants discharged ...

Relative reactivity of DTPA, immunoreactive antibody-DTPA conjugates, and nonimmunoreactive antibody-DTPA conjugates toward indium-111.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1985
Anti-human serum albumin antibody (Ab) was reacted with cyclic DTPA dianhydride (cDTPAA) at various cDTPAA/Ab molar ratios between 1 and 40. Using a carrier In titration method for DTPA and DTPA-antibody conjugate (Ab-DTPA), we determined that the above reactions produced between 0.1 and 11 DTPA molecules per either immunoreactive antibody (sAb) or ...

Urinary clearance of 113mIn-DTPA and 99mTc-(Sn)DTPA measured by external arm counting

Urological Research, 1977
Single shot glomerular filtration rate measurements involving chelates (113mIn-DTPA, 99mTc-DTPA etc) assume direct loss from the plasma to urine via glomerular filtration and excretion. Inherent errors, due to considerable uptake of activity in tissue and uncertainty of complete bladder emptying are ignored and taking of half-hourly blood and urine ...
