Nanoparticles for nucleation of heavy metal iodide films: mercuric iodide and bismuth tri-iodide cases

Mercuric iodide and bismuth tri-iodide nanoparticles were synthesized by suspension in octadecene, from Hg(NO3)(2)center dot H2O and I-2, and from Bi(NO3)(3)center dot 5H(2)O and I-2, respectively. The best synthesis conditions were 2 hrs. at 60-70 degrees C, followed by 10 min. at 95-110 degrees C for mercuric iodide nanoparticles, and 4 hrs. at 80-110 degrees C, followed by 10 min. at 180-210 degrees C for bismuth tri-iodide ones. Nanoparticles were then washed and centrifugated with ether repeatedly. Compounds identity was confirmed by X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Nanoparticles were characterized by transmission (TEM) and scanning (SEM) electron microscopy. Disk-like and squared mercuric iodide nanostructures were obtained, 80-140 nm and 100-125 nm in size respectively. Rounded and rod-like bismuth tri-iodide nanoparticles, 30-500 nm in size were obtained. Acetonitrile and isopropanol suspensions of mercuric iodide nanoparticles, and acetonitrile suspension of bismuth tri-iodide nanoparticles exhibited peak maxima shifts in their UV-Vis spectra, as was reported for nanoparticles of other materials. It is the first time that mercuric iodide and bismuth tri-iodide nanoparticles are synthesized by the suspension method, although uniform shape and size distributions have not yet been obtained. They offer interesting perspectives for crystalline film nucleation, for improving current applications of these materials, as far as for opening new ones.

Iodide transport and breast cancer

Breast cancer is the second most common cancer worldwide and the leading cause of cancer death in women, with incidence rates that continue to rise. The heterogeneity of the disease makes breast cancer exceptionally difficult to treat, particularly for those patients with triple-negative disease. To address the therapeutic complexity of these tumours, new strategies for diagnosis and treatment are urgently required. The ability of lactating and malignant breast cells to uptake and transport iodide has led to the hypothesis that radioiodide therapy could be a potentially viable treatment for many breast cancer patients. Understanding how iodide is transported, and the factors regulating the expression and function of the proteins responsible for iodide transport, is critical for translating this hypothesis into reality. This review covers the three known iodide transporters – the sodium iodide symporter, pendrin and the sodium-coupled monocarboxylate transporter – and their role in iodide transport in breast cells, along with efforts to manipulate them to increase the potential for radioiodide therapy as a treatment for breast cancer.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthesis of a Stable Primary-Alkyl-Substituted Selenenyl Iodide and Its Hydrolytic Conversion to the Corresponding Selenenic Acid

A primary-alkyl-substituted selenenyl iodide was successfully synthesized through oxidative iodination of a selenol with N-iodosuccinimide by taking advantage of a cavity-shaped steric protection group. The selenenyl iodide exhibited high thermal stability and remained unchanged upon heating at 100 degrees C for 3 h in [D-8]toluene. The selenenyl iodide was reduced to the corresponding selenol by treatment with dithiothreitol. Hydrolysis of the selenenyl iodide under alkaline conditions afforded the corresponding selenenic acid almost quantitatively, corroborating the chemical validity of the recent proposal that hydrolysis of a selenenyl iodide to a selenenic acid is potentially involved in the catalytic mechanism of an iodothyronine deiodinase.

Cathodic stripping voltammetric determination of iodide using disposable sensors

The World Health Organization considers iodide deficiency diseases (IDD) to be a public health problem. The main indicator to access IDD is urinary iodide, since approximately 90% of the ingested iodide uses this clearance path, with urine being a preferable target for the analysis. In this work, two screen-printed carbon electrode (SPCE) based sensors were developed to determine iodide by using only a single drop of sample. A first approach based on a SPCE proves to selectively determine iodide through the control of the cathodic stripping voltammetric (CSV) parameters. However, this strategy exhibits a gap in determining trace iodide concentrations, which is improved by modifying the working electrode surface with a chitosan coating. The performance of this new CS/SPCE-based sensor was compared with that of the previous SPCE-based sensor, showing improved iodide determination sensitivity. A limit of detection of 1.0 x 10(-8) M and a linear analysis range of 0.15-500 mu M were achieved with this sensor. The application of both sensors to real-life samples found values close to those determined by the standard Sandell-Kolthoff spectrophotometric method, proving them to be powerful analytical tools for iodide determination in different kinds of samples, including biological matrices.

Dietary Iodine Sufficiency and Moderate Insufficiency in the Lactating Mother and Nursing Infant: A Computational Perspective

The Institute of Medicine recommends that lactating women ingest 290 mu g iodide/d and a nursing infant, less than two years of age, 110 mu g/d. The World Health Organization, United Nations Children’s Fund, and International Council for the Control of Iodine Deficiency Disorders recommend population maternal and infant urinary iodide concentrations >= 100 mu g/L to ensure iodide sufficiency. For breast milk, researchers have proposed an iodide concentration range of 150-180 mu g/L indicates iodide sufficiency for the mother and infant, however no national or international guidelines exist for breast milk iodine concentration. For the first time, a lactating woman and nursing infant biologically based model, from delivery to 90 days postpartum, was constructed to predict maternal and infant urinary iodide concentration, breast milk iodide concentration, the amount of iodide transferred in breast milk to the nursing infant each day and maternal and infant serum thyroid hormone kinetics. The maternal and infant models each consisted of three sub-models, iodide, thyroxine (T4), and triiodothyronine (T3). Using our model to simulate a maternal intake of 290 mu g iodide/d, the average daily amount of iodide ingested by the nursing infant, after 4 days of life, gradually increased from 50 to 101 mu g/day over 90 days postpartum. The predicted average lactating mother and infant urinary iodide concentrations were both in excess of 100 mu g/L and the predicted average breast milk iodide concentration, 157 mu g/L. The predicted serum thyroid hormones (T4, free T4 (fT4), and T3) in both the nursing infant and lactating mother were indicative of euthyroidism. The model was calibrated using serum thyroid hormone concentrations for lactating women from the United States and was successful in predicting serum T4 and fT4 levels (within a factor of two) for lactating women in other countries. T3 levels were adequately predicted. Infant serum thyroid hormone levels were adequately predicted for most data. For moderate iodide deficient conditions, where dietary iodide intake may range from 50 to 150 mu g/d for the lactating mother, the model satisfactorily described the iodide measurements, although with some variation, in urine and breast milk. Predictions of serum thyroid hormones in moderately iodide deficient lactating women (50 mu g/d) and nursing infants did not closely agree with mean reported serum thyroid hormone levels, however, predictions were usually within a factor of two. Excellent agreement between prediction and observation was obtained for a recent moderate iodide deficiency study in lactating women. Measurements included iodide levels in urine of infant and mother, iodide in breast milk, and serum thyroid hormone levels in infant and mother. A maternal iodide intake of 50 mu g/d resulted in a predicted 29-32% reduction in serum T4 and fT4 in nursing infants, however the reduced serum levels of T4 and fT4 were within most of the published reference intervals for infant. This biologically based model is an important first step at integrating the rapid changes that occur in the thyroid system of the nursing newborn in order to predict adverse outcomes from exposure to thyroid acting chemicals, drugs, radioactive materials or iodine deficiency.

SEPARATION OF IODIDE AND IODATE BY ANION-EXCHANGE RESIN AND DETERMINATION OF THEIR IONS IN SURFACE-WATER

Analytical methods for the determination of iodide and iodate ions in surface water were investigated. Iodide in water was adsorbed on an anion exchange resin column and eluted as iodate which was then oxidized with permanganate. For the colorimetric determination of iodide, the Leuco Crystal Violet method was adopted. To obtain the concentration of iodate in surface water, total iodine was determined by a similar analytical method after reducing iodate to iodide with sulfurous acid. The concentration of iodate was calculated by subtracting the concentration of iodide from that of total iodine. The concentration of total iodine was 2.5-mu-g/l in rain water and 5 approximately 7-mu-g/l in river and tap waters. The analytical results of iodide and iodate in rain and river waters showed that the ratio of iodate to iodide in river water was higher than that in rain water. On the other hand, the analytical results for tap water showed that its ratio of iodate to iodide was conspicuously higher than that of river water.

EXTERNAL IODINE ATOMS INFLUENCE OVER THE INTERSYSTEM CROSSING RATE OF A CYANINE IODIDE-ION PAIR IN BENZENE SOLUTION

The photochemical and photophysical properties of N,N’-dibutyltetramethylindocarbocyanine iodide {[TMIC]Bu+I-} in benzene solution were examined by absorption spectroscopy and flash photolysis on a picosecond time scale. In benzene solution, the dye iodide exists nearly exclusively as an ion pair. Under these conditions the absorption spectrum of the cyanine dye is perturbed by the iodide ion by a dispersion interaction. Irradiation of the cyanine iodide ion pair generates the triplet-state cyanine.
