Custer, Christine M. published the artcileLegacy and Contaminants of Emerging Concern in Tree Swallows Along an Agricultural to Industrial Gradient: Maumee River, Ohio, Safety of Diatrizoic Acid, the main research area is Tachycineta contaminant river water pollution PBDE PAH PCB Ohio; Birds; Desethylatrazine; Maumee River; Perfluorinated substances; Polybrominated diphenyl ethers; Tree swallows.

Exposure to multiple classes of contaminants, both legacy and contaminants of emerging concern (CECs), were assessed in tree swallow (Tachycineta bicolor) tissue and diet samples from 6 sites along the Maumee River, Ohio, USA, to understand both exposure and possible effects of exposure to those CECs for which there are little avian data. The 6 sites represented a gradient from intensive agriculture upstream to highly urbanized and industrial landscapes downstream; 1 or 2 remote Wisconsin lakes were assessed for comparative purposes. Cytochrome P 450 induction, DNA damage, and thyroid function were also assessed relative to contaminant exposure. Bioaccumulative CECs, such as polybrominated di-Ph ethers (PBDEs) and perfluorinated substances, did not follow any upstream to downstream gradient; but both had significantly greater concentrations along the Maumee River than at the remote lake sites. Greater exposure to PBDEs was apparent in swallows at or near wastewater-treatment facilities than at other sites. Total polychlorinated biphenyl and total polycyclic aromatic hydrocarbon concentrations were greater in swallows at downstream locations compared to upstream sites and were associated with higher ethoxyresorufin-O-dealkylase activity. Few herbicides or nonorganochlorine insecticides were detected in swallow tissues or their food, except for atrazine and its metabolite desethylatrazine. Few pharmaceuticals and personal care products were detected except for DEET and iopamidol. Both were detected in most liver samples but not in eggs, as well as detected at the remote lake sites. This is one of the most comprehensive assessments to date of exposure and effects of a wide variety of CECs in birds. Environ Toxicol Chem 2020;00:1-17. 2020 SETAC.

AIM To assess the cleansing efficacy and safety of a new Colon capsule endoscopy (CCE) bowel preparation regimen. METHODS This was a multicenter, prospective, randomized, controlled study comparing two CCE regimens. Subjects were asymptomatic and average risk for colorectal cancer. The second generation CCE system (PillCam COLON 2; Medtronic, Yoqneam, Israel) was utilized. Preparation regimens differed in the 1st and 2nd boosts with the Study regimen using oral sulfate solution (89 mL) with diatrizoate meglumine and diatrizoate sodium solution (“”diatrizoate solution””) (boost 1 = 60 mL, boost 2 = 30 mL) and the Control regimen oral sulfate solution (89 mL) alone. The primary outcome was overall and segmental colon cleansing. Secondary outcomes included safety, polyp detection, colonic transit, CCE completion and capsule excretion ≤ 12 h. RESULTS Both regimens had similar cleansing efficacy for the whole colon (Adequate: Study = 75.9%, Control = 77.3%; P = 0.88) and individual segments. In the Study group, CCE completion was superior (Study = 90.9%, Control = 76.9%; P = 0.048) and colonic transit was more often < 40 min (Study = 21.8%, Control = 4%; P = 0.0073). More Study regimen subjects experienced adverse events (Study = 19.4%, Control = 3.4%; P = 0.0061), and this difference did not appear related to diatrizoate solution Adverse events were primarily gastrointestinal in nature and no serious adverse events related either to the bowel preparation regimen or the capsule were observed There was a trend toward higher polyp detection with the Study regimen, but this did not achieve statistical significance for any size category. Mean transit time through the entire gastrointestinal tract, from ingestion to excretion, was shorter with the Study regimen while mean colonic transit times were similar for both study groups. CONCLUSION A CCE bowel preparation regimen using oral sulfate solution and diatrizoate solution as a boost agent is effective, safe, and achieved superior CCE completion.

Farhat, Ali published the artcileRemoval of Persistent Organic Contaminants by Electrochemically Activated Sulfate, HPLC of Formula: 117-96-4, the main research area is persistent organic contaminant electrochem activated sulfate wastewater.

Solutions of sulfate have often been used as background electrolytes in the electrochem. degradation of contaminants and have been generally considered inert even when high-oxidation-power anodes such as boron-doped diamond (BDD) were employed. This study examines the role of sulfate by comparing electro-oxidation rates for seven persistent organic contaminants at BDD anodes in sulfate and inert nitrate anolytes. Sulfate yielded electro-oxidation rates 10-15 times higher for all target contaminants compared to the rates of nitrate anolyte. This electrochem. activation of sulfate was also observed at concentrations as low as 1.6 mM, which is relevant for many wastewaters. Electrolysis of diatrizoate in the presence of specific radical quenchers (tert-butanol and methanol) had a similar effect on electro-oxidation rates, illustrating a possible role of the hydroxyl radical (•OH) in the anodic formation of sulfate radical (SO4•-) species. The addition of 0.55 mM persulfate increased the electro-oxidation rate of diatrizoate in nitrate from 0.94 to 9.97 h-1, suggesting a nonradical activation of persulfate. Overall findings indicate the formation of strong sulfate-derived oxidant species at BDD anodes when polarized at high potentials. This may have pos. implications in the electro-oxidation of wastewaters containing sulfate. For example, the energy required for the 10-fold removal of diatrizoate was decreased from 45.6 to 2.44 kWh m-3 by switching from nitrate to sulfate anolyte.

Schneider, A.-L. published the artcileElectrochemical oxidation of iodinated X-ray contrast media by boron-doped diamond electrodes, Safety of Diatrizoic Acid, the main research area is electrochem oxidation iodinated boron diamond electrode.

Iodinated X-ray contrast media (IXCM) represent widespread water pollutants due to their poor elimination by common wastewater treatment techniques such as aerobic and anaerobic biodegradation In this study, we demonstrate the removal of six IXCM (iotalamic acid, iopamidol, iohexol, iopromide, iomeprol and diatrizoate) by electrochem. treatment with boron-doped diamond electrodes. Experiments were performed with model solutions and field water samples. Electrochem. treatment of IXCM in synthetic solution resulted in complete deiodination and generation of the oxidation product iodate. We observed a dissolved organic carbon (DOC) decrease of 30%-80% in IXCM solutions, indicating partial mineralization. Electrochem. IXCM degradation followed pseudo-first-order kinetics. In experiments with surface water and effluent from a wastewater treatment plant, successful degradation of IXCM was achieved despite the high DOC background. These results demonstrate that electrochem. treatment is a promising method for IXCM removal. Further studies into biodegradation of transformation products are recommended.

Early detection of cancer is increasingly important for being considered to increase the survival rate in the treatment process. The past decades years have witnessed the great progress in the biol. detection application of gold nanoparticles. Herein, we reported a facile one-pot synthesis process to obtain gold nanoparticles (Au@BSA) with bovine serum albumin (BSA) as a biotemplate following with conjugation of diatrizoic acid (DTA) for a potential X-ray computed tomog. (CT) imaging contrast agent (Au@BSA-DTA). The as-prepared biomimetic material was characterized systematically by several techniques. It was shown that the prepared biomaterial is colloid stable under the tested range of pH and temperature The cell cytotoxicity assay, hemolytic assay and cell morphol. observation showed that Au@BSA-DTA has good biocompatibility and hemocompatibility at a concentration of Au even up to 80μg/mL. Besides, the biomimetic material Au@BSA-DTA with double radiodense elements of Au and iodine displayed much stronger CT imaging effect compared with the traditional small mol. contrast agents, which paves the potential clin. application in cancer early diagnosis.

El-Gendy, Nashwa published the artcileDry powdered aerosols of diatrizoic acid nanoparticle agglomerates as a lung contrast agent, Quality Control of 117-96-4, the main research area is powder aerosol diatrizoate nanoparticle agglomerate lung contrast computed tomog.

Aerosolized contrast agents may improve the resolution of biomedical imaging modalities and enable more accurate diagnosis of lung diseases. Many iodinated compounds, such as diatrizoic acid, have been shown to be safe and useful for radiog. examination of the airways. Formulations of such compounds must be improved in order to allow imaging of the smallest airways. Here, diatrizoic acid nanoparticle agglomerates were created by assembling nanoparticles into inhalable microparticles that may augment deposition in the lung periphery. Nanoparticle agglomerates were fully characterized and safety was determined in vivo. After dry powder insufflation to rats, no acute alveolar tissue damage was observed 2 h post-dose. Diatrizoic acid nanoparticle agglomerates possess the characteristics of an efficient and safe inhalable lung contrast agent.

Bertelkamp, C. published the artcileA predictive multi-linear regression model for organic micropollutants, based on a laboratory-scale column study simulating the river bank filtration process, Related Products of isoquinoline, the main research area is predictive multilinear regression model organic micropollutant river bank filtration; Biodegradation; Organic micropollutants; Predictive model; QSAR; River bank filtration.

This study examined relations between OMP (organic micropollutant) biodegradation rates and the functional groups present in the chem. structure of a mixture of 31 OMPs. OMP biodegradation rates were determined from laboratory-scale columns filled with soil from RBF (river bank filtration) site Engelse Werk of the drinking water company Vitens in The Netherlands. A statistically significant relation was found between OMP biodegradation rates and the functional groups of the mol. structures of OMPs in the mixture The OMP biodegradation rate increased in the presence of carboxylic acids, hydroxyl groups, and carbonyl groups, but decreased in the presence of ethers, halogens, aliphatic ethers, Me groups and ring structures in the chem. structure of the OMPs. The predictive model obtained from the laboratory-scale soil column experiment gave an accurate qual. prediction of biodegradability for ∼70% of the OMPs monitored in the field (80% excluding the glymes). The model was less reliable for the more persistent OMPs (OMPs with predicted biodegradation rates lower or around the standard error =0.77/day) and OMPs containing amide or amine groups. These OMPs should be carefully monitored in the field to determine their removal during RBF.

Xiao, Tingting published the artcileA Dendrimer-Based Dual Radiodense Element-Containing Nanoplatform for Targeted Enhanced Tumor Computed Tomography Imaging, COA of Formula: C11H9I3N2O4, the main research area is gold dendrimer PAMAM folate receptor imaging contrast agent.

The exploration of original computed tomog. (CT) imaging contrast agents with enhanced sensitivity and specificity is currently one of the major challenging tasks for precision medicine. Herein, we develop an innovative nanoprobe of dendrimer-stabilized gold nanoparticles (Au DSNs) linked with folic acid (FA) as a targeting ligand and diatrizoic acid (DTA) for specific enhanced tumor CT imaging. In current work, poly(amidoamine) (PAMAM) dendrimers of generation 5 (G5) with amine termini were adopted to entrap Au NPs through a stepwise complexation/reduction method to achieve a higher Au loading than the conventional one-step complexation/reduction method. The prepared [(Au0)120-G5.NH2] NPs were sequentially functionalized with diatrizoic acid (DTA), a typical CT contrast agent based on iodine(I), FA through a poly(ethylene glycol) (PEG) spacer, and carboxylated PEG monomethyl ether (mPEG-COOH), ended with complete acetylation of the leftover dendrimer amine termini. The generated Au DSNs-DTA-FA (Au core diameter = 5.9 nm) were thoroughly characterized. Our data reveal that the Au DSNs-DTA-FA containing Au and I dual radiodense elements are stable, display enhanced CT imaging performance, much higher than the single-radiodense elemental material solely based on Au or I, and possess a quite good cytocompatibility. With the demonstrated FA-rendered specific targeting, the developed Au DSNs-DTA-FA can be employed as a highly efficient nanoprobe for targeted enhanced CT imaging of cancer cells and a s.c. tumor model. Overall, the created Au DSNs-DTA-FA may be a powerful nanoprobe for specific enhanced CT imaging of various kinds of FA receptor-expressing tumors or biosystems.

Drew, Kurt L. M. published the artcileSize estimation of chemical space: how big is it?, Safety of Diatrizoic Acid, the main research area is drug chem space size estimation.

To estimate the size of organic chem. space and its sub-regions, i.e. drug-like chem. space and known drug space (KDS), anal. of the growth of organic compounds as a function of their carbon atoms based on a power function (f(x) = A × B, C = x) and an exponential function (f(x) = AeBx) was carried out. Also, the statistical distribution of KDS and drug-like chem. space (drugs with good oral-bioavailability) based on their carbon atom count was used to deduce their size. Key findings The power function (f(x) = A × B, C = x) gives a superior fit to the growth of organic compounds leading to an estimate of 3.4 × 109 populating chem. space. KDS is predicted to be 2.0 × 106 mols. and drug-like chem. space is calculated to be 1.1 × 106 compounds The results showed that the values here are much smaller than previously reported. However, the numbers are large but not astronomical. A clear rationale on how we reach these numbers is given, which hopefully will lead to more refined predictions.

Wendel, Friedrich M. published the artcileTransformation of Iopamidol during Chlorination, Recommanded Product: Diatrizoic Acid, the main research area is transformation iopamidol water chlorination.

The transformation of the iodinated x-ray contrast media (ICM) iopamidol, iopromide, iohexol, iomeprol, and diatrizoate was examined in purified water over the pH 6.5-8.5 in the presence of Na hypochlorite, monochloramine, and ClO2. In the presence of aqueous Cl, only iopamidol was transformed. All other ICM did not show significant reactivity, regardless of the oxidant used. Chlorination of iopamidol followed a 2nd order reaction, with an observed rate constant of up to 0.87/M-s (±0.021/M-s) at pH 8.5. The hypochlorite anion was identified to be the reactive Cl species. Iodine was released during the transformation of iopamidol, and was mainly oxidized to iodate. Only a small percentage (<2% after 24 h) was transformed to known organic iodinated disinfection byproducts (DBPs) of low mol. weight Some of the I was still present in high-mol. weight DBPs. The chem. structures of these DBPs were elucidated via MSn fragmentation and NMR. Side chain cleavage was observed as well as the exchange of I by Cl. An overall transformation pathway was proposed for the degradation of iopamidol. CHO cell chronic cytotoxicity tests indicate that chlorination of iopamidol generates a toxic mixture of high mol. weight DBPs (LC50 332 ng/μL).
