McCall, Michael D published the artcileHistopaque provides optimal mouse islet purification kinetics: comparison study with Ficoll, iodixanol and dextran., Related Products of isoquinoline, the main research area is .

Islet transplantation has become a very promising treatment for type 1 diabetes. To facilitate further clinical improvements in this exciting field, rodent islets are used to evaluate new strategies and modifications. One method to purify islets is on a density gradient, although the optimal gradient component can be debated. N=6 separate mouse islet isolations were used and the resulting islets were separated and purified on either a Ficoll, Histopaque, Dextran or Iodixanol gradient. Islets were assessed for recovery, viability, purity and in vitro functionality. Aliquots were transplanted into diabetic mice to assess in vivo functionality and survival. There was no difference in the number of islets recovered across groups nor in the size of recovered islets. Use of a Ficoll or Histopaque gradient led to the most pure and viable islets in comparison to Dextran and Iodixanol. Functionally, islets isolated on a Ficoll gradient had the highest glucose-stimulated insulin release in vitro while performing equally to Histopaque and Dextran gradients in vivo. Using a Ficoll gradient, however, comes at a higher monetary cost. We recommend using a Histopaque gradient, which led to the isolation of viable and functional islets with a reduced cost as compared to a Ficoll gradient.

Navedo, Juan G. published the artcileAssessing the effects of human activities on the foraging opportunities of migratory shorebirds in Austral high-latitude bays, Category: isoquinoline, the main research area is .

Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures compatible with migratory processes and associated biodiversity. Here, we assess the effects of human presence on the foraging opportunities of Hudsonian godwits (Limosa haemastica, a trans-hemispheric migratory shorebird) during their non-breeding season on Chiloé Island, southern Chile. We compared bird d. and time spent foraging in two similar bays with contrasting disturbance levels: human presence (mostly seaweed harvesters accompanied by dogs) was on average 0.9±0.4 people per 10 ha in the disturbed bay, whereas it was negligible (95% days absent) in the non-disturbed bay. Although overall abundances were similar between bays, godwit d. was higher in the non-disturbed bay throughout the low tide period. Both days after the start of the non-breeding season and tidal height significantly affected godwit d., with different effects in either bay. Time spent foraging was significantly higher in the non-disturbed bay (86.5±1.1%) than in the disturbed one (81.3±1.4%). As expected, godwit d. significantly decreased with the number of people and accompanying dogs in the disturbed bay. Our results indicate that even a low d. of people and dogs can significantly reduce the foraging opportunities of shorebirds. These constraints, coupled with addnl. flushing costs, may neg. affect godwits’ pre-migratory fattening. Hence, as a first step we suggest limiting human presence within bays on Chiloé to 1 person per 10 ha and banning the presence of accompanying dogs in sensitive conservation areas.

Bakhshi, Sameer published the artcilePediatric nonlymphoblastic non-Hodgkin lymphoma: baseline, interim, and posttreatment PET/CT versus contrast-enhanced CT for evaluation–a prospective study., SDS of cas: 117-96-4, the main research area is .

PURPOSE: To prospectively examine the roles of positron emission tomography (PET)/computed tomography (CT) and conventional contrast material-enhanced CT at baseline, after two cycles of chemotherapy, and after completion of chemotherapy in pediatric patients with nonlymphoblastic non-Hodgkin lymphoma (NHL) who were treated with similar standard treatment protocols. MATERIALS AND METHODS: The institutional ethics committee approved the study protocol, and all patients were enrolled after written informed consent was obtained. Patients with nonlymphoblastic NHL were prospectively enrolled between January 2008 and March 2010. Patients underwent contrast-enhanced CT and PET/CT for staging and for response assessment after two cycles of chemotherapy (interim) and treatment completion. Complete metabolic response versus no metabolic response at PET/CT and complete response versus no complete response at contrast-enhanced CT was analyzed by using Kaplan-Meier survival analysis. RESULTS: The final study included 34 patients with nonlymphoblastic NHL (median age, 10.5 years). Baseline PET/CT and contrast-enhanced CT showed concordance in depiction of 112 disease sites; PET/CT depicted 18 more disease sites and two fewer disease sites than contrast-enhanced CT (P = .0003). Disease in five of 34 patients was upstaged, and disease in no patient was downstaged at PET/CT. There was 100% (four of four) concordance between bone marrow involvement at biopsy and stage at PET/CT. The median length of follow-up was 20.3 months. Response at interim PET/CT and contrast-enhanced CT could not predict progression-free survival (PFS) (P = .083 and .18, respectively) or overall survival (OS) (P = .159 and.08, respectively). Posttreatment PET/CT and contrast-enhanced CT findings could predict PFS (P = .036 and .002, respectively) and posttreatment contrast-enhanced CT findings could predict OS (P = .035); however, posttreatment PET/CT findings could not predict OS (P = .067). CONCLUSION: PET/CT depicts additional sites compared with contrast-enhanced CT and results in upstaging of disease. Either PET/CT or contrast-enhanced CT may be used for response assessment and prognostication in stage III or IV nonlymphoblastic pediatric NHL.

Helbren, Emma published the artcileCT colonography: clinical evaluation of a method for automatic coregistration of polyps at follow-up surveillance studies., Quality Control of 117-96-4, the main research area is .

PURPOSE: To evaluate the accuracy of a method of automatic coregistration of the endoluminal surfaces at computed tomographic (CT) colonography performed on separate occasions to facilitate identification of polyps in patients undergoing polyp surveillance. MATERIALS AND METHODS: Institutional review board and HIPAA approval were obtained. A registration algorithm that was designed to coregister the coordinates of endoluminal colonic surfaces on images from prone and supine CT colonographic acquisitions was used to match polyps in sequential studies in patients undergoing polyp surveillance. Initial and follow-up CT colonographic examinations in 26 patients (35 polyps) were selected and the algorithm was tested by means of two methods, the longitudinal method (polyp coordinates from the initial prone and supine acquisitions were used to identify the expected polyp location automatically at follow-up CT colonography) and the consistency method (polyp coordinates from the initial supine acquisition were used to identify polyp location on images from the initial prone acquisition, then on those for follow-up prone and follow-up supine acquisitions). Two observers measured the Euclidean distance between true and expected polyp locations, and mean per-patient registration accuracy was calculated. Segments with and without collapse were compared by using the Kruskal-Wallace test, and the relationship between registration error and temporal separation was investigated by using the Pearson correlation. RESULTS: Coregistration was achieved for all 35 polyps by using both longitudinal and consistency methods. Mean ± standard deviation Euclidean registration error for the longitudinal method was 17.4 mm ± 12.1 and for the consistency method, 26.9 mm ± 20.8. There was no significant difference between these results and the registration error when prone and supine acquisitions in the same study were compared (16.9 mm ± 17.6; P = .451). CONCLUSION: Automatic endoluminal coregistration by using an algorithm at initial CT colonography allowed prediction of endoluminal polyp location at subsequent CT colonography, thereby facilitating detection of known polyps in patients undergoing CT colonographic surveillance.

Vargas, Hebert Alberto published the artcileBone metastases in castration-resistant prostate cancer: associations between morphologic CT patterns, glycolytic activity, and androgen receptor expression on PET and overall survival., Application In Synthesis of 117-96-4, the main research area is .

PURPOSE: To compare the features of bone metastases at computed tomography (CT) to tracer uptake at fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) and fluorine 18 16β-fluoro-5-dihydrotestosterone (FDHT) PET and to determine associations between these imaging features and overall survival in men with castration-resistant prostate cancer. MATERIALS AND METHODS: This is a retrospective study of 38 patients with castration-resistant prostate cancer. Two readers independently evaluated CT, FDG PET, and FDHT PET features of bone metastases. Associations between imaging findings and overall survival were determined by using univariate Cox proportional hazards regression. RESULTS: In 38 patients, reader 1 detected 881 lesions and reader 2 detected 867 lesions. Attenuation coefficients at CT correlated inversely with FDG (reader 1: r = -0.3007; P < .001; reader 2: r = -0.3147; P < .001) and FDHT (reader 1: r = -0.2680; P = .001; reader 2: r = -0.3656; P < .001) uptake. The number of lesions on CT scans was significantly associated with overall survival (reader 1: hazard ratio [HR], 1.025; P = .05; reader 2: HR, 1.021; P = .04). The numbers of lesions on FDG and FDHT PET scans were significantly associated with overall survival for reader 1 (HR, 1.051-1.109; P < .001) and reader 2 (HR, 1.026-1.082; P â‰?.009). Patients with higher FDHT uptake (lesion with the highest maximum standardized uptake value) had significantly shorter overall survival (reader 1: HR, 1.078; P = .02; reader 2: HR, 1.092; P = .02). FDG uptake intensity was not associated with overall survival (reader 1, P = .65; reader 2, P = .38). CONCLUSION: In patients with castration-resistant prostate cancer, numbers of bone lesions on CT, FDG PET, and FDHT PET scans and the intensity of FDHT uptake are significantly associated with overall survival.

Zou, Hongyan published the artcileTemporal Variation of Chemical Persistence in a Swedish Lake Assessed by Benchmarking, Application of Diatrizoic Acid, the main research area is temporal variation chem persistence Swedish lake benchmarking.

Chem. benchmarking was used to study the temporal variation of the persistence of chem. contaminants in a Swedish lake. The chems. studied included 12 pharmaceuticals, an artificial sweetener, and an x-ray contrast agent. Measurements were conducted in late spring, late autumn, and winter. The transformation half-life in the lake could be quantified for 7 of the chems. It ranged from several days to hundreds of days. For 5 of the chems. (bezafibrate, climbazole, diclofenac, furosemide, and hydrochlorothiazide), the measured persistence was lower in late spring than in late autumn. This may have been caused by lower temperatures and/or less irradiation during late autumn. The seasonality in chem. persistence contributed to changes in chem. concentrations in the lake during the year. The impact of seasonality of persistence was compared with the impact of other important variables determining concentrations in the lake: chem. inputs and water flow/dilution The strongest seasonal variability in chem. concentration in lake water was observed for hydrochlorothiazide (over a factor of 10), and this was attributable to the seasonality in its persistence.

Llorca, Marta published the artcileSuspect screening of emerging pollutants and their major transformation products in wastewaters treated with fungi by liquid chromatography coupled to a high resolution mass spectrometry, COA of Formula: C11H9I3N2O4, the main research area is suspect screening emerging pollutant major transformation product wastewater fungi; liquid chromatog coupled high resolution mass spectrometry; Bioremediation of wastewaters; LC–HRMS; Post target screening; Suspect screening of transformation products; Trametes versicolor.

A new approach for the screening of 33 pharmaceuticals and 113 of their known transformation products in wastewaters is based on the anal. of samples by liquid chromatog. coupled to high resolution mass spectrometry (HRMS) followed by data processing using specific software and manual confirmation. A home-made library was built with the transformation products reported in literature for the target pharmaceuticals after treatment with various fungi. The method was applied to the search of these contaminants in 67 samples generated along treatment of wastewaters with white-rot fungus Trametes versicolor. The screening methodol. allowed the detection of different transformation products (TPs) generated from degradation of parent compounds after fungal treatment. This approach can be a useful tool for the rapid screening and tentative detection of emerging contaminants during water treatment in both full and batch-scale studies when pure standards are not available.

Feng, Mingbao published the artcileAccelerated Oxidation of Organic Contaminants by Ferrate(VI): The Overlooked Role of Reducing Additives, Synthetic Route of 117-96-4, the main research area is ferrate catalytic oxidation organic contaminant wastewater treatment.

This paper presents an accelerated ferrate(VI) (FeVIO42-, FeVI) oxidation of contaminants in 30 s by adding 1-electron and 2-electron transfer reductants (R(1) and R(2)). An addition of R(2) (e.g., NH2OH, AsIII, SeIV, PIII, and NO2-, and S2O32-) results in FeIV initially, while FeV is generated with the addition of R(1) (e.g., SO32-). R(2) additives, except S2O32-, show the enhanced oxidation of 20-40% of target contaminant, trimethoprim (TMP). Comparatively, enhanced oxidation of TMP was up to 100% with the addition of R(1) to FeVI. Addition of S2O32- (i.e., R(2)) also achieves the enhanced oxidation to 100%. Removal efficiency of TMP depends on the molar ratio ([R(1)]:[FeVI] or [R(2)]:[FeVI]). Most of the reductants have the highest removal at molar ratio of âˆ?.125. A FeVI-S2O32- system also oxidizes rapidly a wide range of organic contaminants (pharmaceuticals, pesticides, artificial sweetener, and x-ray contrast media) in H2O and real H2O matrixes. FeV and FeIV as the oxidative species in the FeVI-S2O32–contaminant system are elucidated by determining removal of contaminants in oxygenated and deoxygenated H2O, applying probing agent, and identifying oxidized products of TMP and sulfadimethoxine (SDM) by FeVI-S2O32- systems. Significantly, elimination of SO2 from sulfonamide (i.e., SDM) is observed for the 1st time.

Azais, Antonin published the artcileEvidence of solute-solute interactions and cake enhanced concentration polarization during removal of pharmaceuticals from urban wastewater by nanofiltration, Recommanded Product: Diatrizoic Acid, the main research area is pharmaceutical removal efficiency nanofiltration wastewater treatment urban area; Fouling; Matrix influence; Nanofiltration; Pharmaceutically active compounds; Wastewater reuse.

The objective of this paper is to help understanding the distinctive influence of the matrix and of the flux decline (e.g. through the cake enhanced concentration polarization (CECP) phenomenon) on the removal mechanisms of four pharmaceutically active compounds (PhACs) from wastewater treatment plant (WWTP) effluent by nanofiltration (NF). PhACs which are commonly encountered in secondary treated effluent were spiked in various matrix (real and synthetic) to investigate the sep. and synergetic effects of the organic and ionic environment on PhACs rejection by two com. membranes (NF-90 and NF-270). With pure water, rejection of NF membranes is dependent on the type of PhACs and of the permeate flux variations. Then, it appeared that the rejection of PhACs by NF-90 was poorly influenced by the type of compounds, because of the prevalence of steric mechanisms, but rather influenced by permeate flux variations and thus to fouling. For this tight NF membrane, CECP impacts PhACs rejection at the start of filtration while after a dense cake is formed, it became enhanced. On the contrary, rejections of PhACs by the NF-270 were enhanced during the filtration of the real wastewater in comparison with spiked pure water. It appeared that for loose-NF membranes, PhACs rejection is mainly governed by solute-solute interactions (EfOM-compound association) or electrostatic membrane-solute interactions. Finally, it seems that calcium concentration of the effluent is a critical parameter for the rejection of PhACs as it alters both the availability of sites for PhACs association and the fouling layer d. Rejections of the NF-270 were neg. impacted in the presence of Ca2+. Such a study has practical implications for further understanding of the fate of trace organic compounds during nanofiltration of wastewater for reuse applications.

Brunsch, A. published the artcileA monitoring strategy in view of Water Framework Directive requirements with focus on anthropogenic micropollutants, Name: Diatrizoic Acid, the main research area is water framework directive anthropogenic micropollutant monitoring strategy.

The Water Framework Directive of the European Commission sets down regulatory requirements regarding harmful chem. substances in surface waters and measures to reduce such presence. Member states are responsible for implementation. In Germany the surface water ordinance (Oberflachengewasser-verordnung) was adopted for this purpose in 2011. Currently the matter of whether to extend the list of substances to be reduced or eliminated in surface waters is being reconsidered. Among the types of substances under discussion are pharmaceuticals. To fulfil the requirements of the Water Framework Directive, it is essential that sophisticated local monitoring programs be conducted to obtain a useful knowledge base regarding the water quality situation of surface waters. Such a program is applied to the Swist watercourse, a tributary of the Rhine river. One component is establishment of a balancing of emissions for the purpose of identifying relevant sources, pathways and inputs of pollutants. Monitoring data is thus obtained from various source areas such as wastewater treatment plants, sewerage system outlets and runoff from landscape. To understand cause-effect relationships and to validate emission data, an immission monitoring strategy has also been established for the Swist. Furthermore, a scenario based measuring initiative with focus on anthropogenic micropollutants has been recently introduced into the existing monitoring program. This initiative is being conducted to expand knowledge of both the fate and behavior of anthropogenic micropollutants in the Swist watercourse. First results show the appearance of a range of micropollutants, with highest concentrations of Diclofenac, Carbamazepin and Diatrizoat.
