Radiopaque poly(2-hydroxyethyl methacrylate) particles containing silver iodide complexes tested on cell culture

Silver iodide complexes have been used as an effective radiopacifying agent to prepare radiopaque poly(2-hydroxyethyl methacrylate) (poly(HEMA)) particles. Incorporation of silver iodide complexes inside the poly(HEMA) particles was achieved by first swelling particles in potassium iodide solution and precipitating the silver iodide complexes using a 30 wt% solution of silver nitrate. The dry particles contained 15 wt% of silver iodide complexes. Particles were easily monitored using a standard imaging technique based on X-ray absorption. Toxicity of the particles has been determined in in vitro experiments on a cell culture. As no inhibition of growth of cells surrounding the particles was observed, they can be considered non-toxic.

COMPARISON OF TWO IODINE QUANTIFICATION METHODS IN AN ARTIFICIAL SEAWATER SYSTEM HOUSING WHITE-SPOTTED BAMBOO SHARKS (CHILOSCYLLIUM PLAGIOSUM)

Iodine is an essential micronutrient for elasmobranchs in order to prevent goiter. Preventing goiter requires bioavailable iodide: either oral iodide or maintaining adequate aquarium water iodide concentrations. The objective of this study was to determine how oral and water supplementation affected iodine (I-2) and iodide (I) concentrations in artificial seawater aquaria housing captive white-spotted bamboo sharks (Chiloscyl hum plagiosum). Daily water samples were collected and free iodine (I-2) was determined using ultraviolet-absorbance spectrophotometry (a relatively simple in-house assay) and total iodide (I) via liquid chromatography (a more time- and expertise-intense quantification method) to learn the effects of supplementation. One water system received iodine and iodide supplementation in the form of 5% Lugol’s iodine solution added directly to the water, while a second water system received no supplementation. In addition, one tank of sharks in each water system received oral iodide supplementation. Results indicated that oral supplementation provides greater increases in water concentrations of bioavailable iodide (I) than direct water supplementation. In addition, the chromatographic results suggested that iodide is present in higher concentrations in the systems not receiving water supplementation. Increased iodide concentrations were detected in water samples after water changes and after oral iodide supplementation was administered, but total iodine (I-2) concentration changes were not detectable within the same time frame.

A novel fluorometric and colorimetric sensor for iodide determination using DNA-templated gold/silver nanoclusters

Determination of iodide ions has attracted considerable interest due to the importance and urgency. In the current work, we have developed a novel fluorescent and colorimetric platform for simple and selective detection of iodide ions based on the DNA-templated gold/silver nanoclusters (DNA-Au/Ag NCs). The detection system is based on the unique interaction between iodide ions and DNA-Au/Ag NCs, which shows an obvious fluorescence quenching with the addition of iodide ions and a good linear range from 0 to 10 mu mol/L for iodide ions. In the mean time, the detection system also exhibits an obvious color change from colorless transparent to purple red with the addition of iodide ions. Furthermore, the proposed system has been successfully applied for determination of iodide ions in real water samples.

Sodium/iodide symporter: physiopathological aspects and therapeutic perspectives

The existence of the natriuric/iodide symporter (NIS) represents a new view to understand the thyroid metabolism of iodide. Due to its cellular localisation on basolateral membrane, this transporter exerts an essential role in the biological functions of the thyroid, especially the capacity to accumulate iodide into the thyrocytes. Clinical perspectives of NIS activity modulation would ameliorate the diagnosis and the treatment of thyroid diseases by using radioisotopes transported by the NIS (131 iodide, 99m technetium, 188 rhenium). The study of the regulation pathways modulating the expression and the activity of the symporter NIS, would allow to understand pathogeny of benign or malignant diseases of the thyroid gland. The relative facility of the therapy management by 131 iodide and its good efficiency associated to the recent advance of NIS function also give an interesting perspective to the gene therapy treatment of the nonthyroid cancers despite existent methodological problems.

Cyclic AMP impairs the PRL stimulation of iodide uptake into mouse mammary tissues

In earlier studies the uptake of iodide into mammary cells was found to occur by a mechanism similar to that in thyroid cells (i.e., the uptake occurs via a sodium-iodide symporter that is inhibited by perchlorate and thiocyanate). Although cyclic AMP stimulates the iodide transport mechanism in thyroid cells, the present studies show that cyclic AMP, as well as pharmacological agents that elevate cyclic AMP, impair iodide uptake into mammary cells. In addition, elevated cyclic AMP levels interfere with the PRL stimulation of iodide uptake as well as iodide incorporation into proteins in mammary tissues. Clearly, cyclic AMP has opposite effects on regulating iodide uptake processes in mammary versus thyroid cells.

The effects of amitrole on thyroglobulin and iodide uptake in FRTL-5 cells

Thyroid is a frequent target for endocrine effects of pesticides. Thyroglobulin (TG) and iodide uptake are crucial to thyroid hormone synthesis and may be targets of thyroid-disrupting chemicals. In our study, thyroid follicular FRTL-5 cells were treated with amitrole, an inhibitor of the thyroid peroxidase (TPO), and the effects on TG and total iodide uptake were observed. The results showed that 1 – 100 mg/L amitrole had no marked effects on FRTL-5 cell proliferation and DNA synthesis. However, it significantly increased the transcription of tg gene and inhibited the total iodide uptake. And 10 – 100 mg/L amitrole significantly decreased TG in the culture medium. The data suggests amitrole may disrupt the expression and secretion of TG and iodide uptake.

Macroscopic recognition of iodide by polymer appended calix[4]amidocrown resin

The current study reveals the synthesis of polymer appended Calix[4]amidocrown-5 with specific binding affinity for iodide at ppm-level. The low detection limits are observed via UV-vis and fluorescence spectroscopy. The time-dependent solution and solid-state I-127 NMR studies with 18.8 and 19 ppm shifts, indicate a strong sensing nature of resin towards iodide ion. A significant reduction in surface area and pore volume with higher thermostability of resin after iodide uptake indicated iodide inclusion in the amidocrown cavity. The mechanism of iodide sensing may be governed by noncovalent interactions of NH and OH protons present in amidocrown and phenyl ring as observed in terms of emission enhancement in fluorescence spectroscopy. The binding affinity and stoichiometric determinations are determined by Benesi-Hildebrand and Jobs plots, respectively.
