Evaluation of iohexol clearance to estimate glomerular filtration rate in normal horses
… urine collection. Recently, tests using iohexol, a radiographic contrast agent, have been developed to estimate the GFR in human beings, pigs, sheep, dogs, cats and horse foals with results that have been validated by traditional standards. Serum clearance of a substance that is freely …

Evaluation of Iohexol Clearance to Estimate Glomerular Filtration Rate in Normal Horse Foals
… urine collection. Recently, tests using iohexol, a radiographic contrast agent, have been developed to estimate the GFR in human beings, dogs and cats with results that have been validated by traditional standards. Most testing protocols require a single bolus injection of iohexol, …

Development of a simple HPLC-UV method for determination of GFR by serum iohexol clearance
… the best indicator of kidney function. Iohexol, a contrast agent, is currently considered to be a reference marker since it meets all the requirements of an ideal GFR marker. The aim of this study was to develop and validate a method for iohexol measurement using high performance liquid …

Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model
… H2O), 0.5M gadodiamide (0.78 Osm/kg), 0.5M iohexol (190 mg I/mL; 0.42 Osm/kg), 0.18M iohexol (70 mg I/mL; with an x-ray attenuation equal to that of 0.5M Gd-CM at 80 kVp) and saline; 2) 0.5M gadopentetate, 0.5M gadodiamide, 0.5M iohexol and mannitol solutions iso-osmotic to these CM; 3) 1.0M …

Monitoring Photocatalytic Degradation of X-ray Contrast Media with Raman Spectroscopy
<p>X-ray contrast media such as diatrizoate and iohexol have been found in wastewater and drinking water and are difficult to remove because they are resistant to water treatment processes. A removal process can be started with ultraviolet photocatalytic degradation of X-ray contrast media in the …

DEVELOPMENT OF A NOVEL APPROACH TO ASSESS QUALITATIVE AND QUANTITATIVE DYNAMICS ASSOCIATED WITH THE SUBCUTANEOUS OR INTRAMUSCULAR ADMINISTRATION OF PHARMACEUTICALS AND ASSOCIATED PARENTERAL DELIVERY SYSTEMS
… tissue dispersion and the systemic exposure of iohexol, administered subcutaneously by two delivery systems in human volunteers. The primary finding of this work was the demonstration that CT scanning may be combined with a systemic exposure assessment to provide an effective paradigm for …

Calculation of the effective atomic number for the iodine contrast agent of the varying concentrations
… materials phantom and the phantom containing the iohexol solutions of varying concentrations on the original CT system assembled by the author. A method of the effective atomic number mapping is discussed as a viable alternative to the traditional attenuation-based tomography. The dependency of …

Thermal Analysis of Binding of Organic Pollutants to Titanium Dioxide
… classes of compounds; iodinated contrast agents (iohexol and diatrizoate), polycyclic aromatic hydrocarbons (perylene and pyrene), the antibacterial agent triclosan and the pesticide atrazine, to investigate which of the compounds are adsorbed on the surface of titanium dioxide to undergo direct …

Drinking water disinfection by-products: toxicological impacts and biological mechanisms induced by individual compounds or as complex mixtures
… with chlorine. Four other ICMs (Iopromide, Iohexol, Diatrizoate and Iomeprol) expressed some cytotoxicity over the control, and expressed higher cytotoxicity when chlorinated. Only Iohexol enhanced genotoxicity compared to the chlorinated source water.

Aspects of retransfusion of shed blood in cardiac surgery
… seen. In study III, we evaluated cystatin C with iohexol clearance in a clinical study on patients scheduled for coronary artery bypass grafting (CABG). We found that cystatin C is suitable for monitoring renal function in cardiac surgery. In study IV, the final part of this thesis, we launched a …

The use of non-ionic surfactant vesicles to prevent radiocontrast media-associated damage
… goal is to formulate and characterise a novel iohexol-non-ionic surfactant vesicle (IOX-NIV) delivery system in line with FDA recommendations. This work adds to current knowledge of IOX-associated cytotoxicity and its influence on vessel function. IOX-NIVs were prepared using a 3: 3: 1 mol. …
