Synthesis 99mTc-DTPA-deoxy-D-glucose (99mTc-DTPA-DG) as tumor imaging

AIP Conference Proceedings, 2021
Cancer is the uncontrolled growth of new cells beyond the normal limits. The process by which cancers invade and spread to the other organs is called metastasis, this condition became the leading cause of death. One of detection methods that are currently used to detect tumors and metastatic tissues is conducted with radiopharmaceutical of [18F] fluoro-

Kinetics study of transition metal complexes (Ce–DTPA, Cr–DTPA and V–DTPA) for redox flow battery applications

Electrochimica Acta, 2013
Abstract Electrochemical kinetics of Ce(IV), Cr(III) and V(IV) and their diethylenetriaminepentaacetic acid (DTPA) complexes are studied by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) on Pt-electrode. Kinetic parameters such as potential, limiting current, transfer coefficient, diffusion coefficients, and rate constants ...

The use of DTPA diactivated ester in coupling DTPA to proteins

International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1986
Abstract The use of DTPA bicyclic anhydride of DTPA(1–3) and N-hydroxy succinimide pentaester of DTPA(4) to attach DTPA to different proteins have been reported. However, there is indication in the literature that alternative methods are needed. † We have now synthesized N-hydroxy succinimide diester of DTPA for this purpose. The synthetic procedure

Ni-DTPA doped agarose gel—A phantom material for Gd-DTPA enhancement measurements

Magnetic Resonance Imaging, 1993
In order to study the relationship between the concentration of Gd-DTPA in tissue, and the resulting changes in relaxation times and signal intensity, a phantom material that has similar relaxation times to tissue and that can be doped with Gd-DTPA is required. The "tissue-equivalent" material should not contain Gd; nor should it alter the relaxivities

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

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 ...

Comparison of Ca-DTPA and Zn-DTPA in Removing 234Th from the Rat

Health Physics, 1985
The relative effectiveness of Ca-DTPA and Zn-DTPA as a function of the dose, number of doses and time of their administration in removing 234Th that had been administered as the citrate or nitrate from various rat organs was investigated. With a single early treatment (1.5 min after intravenous injection of 234Th), Zn-DTPA was clearly less effective ...

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 ...

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.
