Pot experiment was conducted at University of Agricultural Sciences, Bangalore, Karnataka, which received five treatments i.e., 0, 5, 10, 15, 20 kg ZnSO4/ha. Among all the Recommended NPK + ZnSO4 @ kg/ha recorded highest mean dry matter yields tomato. The amount zinc extracted by different extractants were in following order as Mehlich-3 - Zn > 0.1 N HCl AB-DTPA 0.01 EDTA DTPA M 1 NH4OAc (pH...

BACKGROUND Airway liquid hyper-absorption is a key pathophysiological link between the genetic mutations of cystic fibrosis (CF) and the development of lung disease. Here we consider whether the clearance of radiolabeled diethylene triamine pentaacetic acid (DTPA) might be used to detect changes in airway liquid absorption. METHODS Tc99m-DTPA was added to the apical (luminal) surface of prima...

Pseudomonas aeruginosa, a Gram-negative bacterium of clinical significance, produces elastase as a predominant exoprotease. Here, we screened a library of chemical compounds currently used for human medication and identified diethylene triamine penta-acetic acid (DTPA, pentetic acid) as an agent that suppresses the production of elastase. Elastase activity found in the prototype P. aeruginosa s...

New measures are needed to rapidly assess emerging treatments for cystic fibrosis (CF) lung disease. Using an imaging approach, we evaluated the absorptive clearance of the radiolabeled small molecule probe diethylene triamine penta-acetic acid (DTPA) as an in vivo indicator of changes in airway liquid absorption. DTPA absorption and mucociliary clearance rates were measured in 21 patients with...

This study investigates the oxidative transformation of diethylenetriaminepentaacetate (DTPA), a synthetic ligand, during drinking water ozonation. The rate coefficients for the reactions of CaDTPA and ZnDTPA with ozone were determined to be 6200 and 3500 150M 1 s , respectively. The reactivity of Fe(III)DTPA towards ozone was found to be much lower ð510 M 1 s Þ, but near neutral pH the reactiv...

BACKGROUND Annexin A5 (anxA5) has been found useful for molecular imaging of apoptosis and other biological processes. METHODS Here, we report an optimised two-step synthesis of annexin A5-diethylene triamine pentaacetic acid (DTPA) (anxA5-DTPA) for positron emission tomography (PET) and single-photon emission computed tomography (SPECT) imaging with a single purification step. The use of a r...
