The effects of different doses of potassium iodate (KIO3) on the malignancy of thyroid cancer were investigated. Results showed that the proliferation, migration, and invasion of SW579 thyroid cancer cells were improved by 10−6M KIO3, which was associated with microRNA(miR)-146a deficit; 10−2M KIO3significantly enhanced miR-146a level and suppressed SW579 cell proliferation, migration, and invasion. The diverse effects of KIO3on SW579 cells were associated with the expression changes in miR-146a targets, Bcl-2, Bax, and caspase-3. Our study concludes that different doses of KIO3have counteracting effects on the malignancy of thyroid cancer through modulating miR-146a level. [ABSTRACT FROM PUBLISHER]

This paper reports the characterization and ferroelectric properties of a dense array of KIO3 nanorods grown inside an aluminum oxide porous film. The pores are cylindrical, having an average diameter of 43 nm and a length of 1 micron. They are uniformly aligned in vertical to the film plane. The crystals grown inside the pores possess a uniform crystallographic orientation, where the normal to their (1[image omitted]1) planes is aligned along the pore axis. Polarization vs. applied electric field measurements, made at room temperature along the direction of the pore axis, yield a ferroelectric hysteresis with a remanent polarization of about 0.55μC/cm2 and a coercive field of about 50 kV/cm.

The kinetics of Ir (III) chloride-catalyzed oxidation of D-glucose by iodate in aqueous alkaline medium was investigated at 45°C. The reaction follows first-order kinetics with respect to potassium iodate in its low concentration range but tends to zero order at its higher concentration. Zero-order kinetics with respect to [D-glucose] was observed. In the lower concentration range of Ir (III) chloride, the reaction follows first kinetics, while the order shifts from first to zero at its higher concentration range. The reaction follows first-order kinetics with respect to [OH-] at its low concentration but tends towards zero order at higher concentration. Variation in [Cl-] and ionic strength of the medium did not bring about any significant change in the rate of reaction. The first-order rate constant increased with a decrease in the dielectric constant of the medium. The values of rate constants observed at four different temperatures were utilized to calculate the activation parameters. Sodium salt of formic acid and arabinonic acid have been identified as the main oxidation products of the reaction. A plausible mechanism from the results of kinetic studies, reaction stoichiometry, and product analysis has been proposed. [ABSTRACT FROM AUTHOR]

The direct conversion of olefins to their corresponding iodohydrins is efficient with I-/IO3- assemblies in an aqueous acidic medium. Iodohydrins were obtained in moderately good yields at ambient reaction conditions without employing any metal catalysts. The addition of IOH across the olefin follows the Morkovnikov's rule.

The loss of set that normally occurs during conventional machine-washing of wool can be inhibited by adding oxidizing agents or thiol-blocking agents to the wash liquor. It is shown in this paper that the addition of several cross-linking agents had little effect, with the exception of formaldehyde and some dialdehydes, which appear to act primarily as thiol-blocking agents. The effect of certain variables, such as solution concentration and pH, on the retention of set and detergency in the presence of these reagents is discussed. [ABSTRACT FROM AUTHOR]

When the felting properties of loose wool, yarn, and fabric are compared, before and after chemical modification, only a poor relationship is found between the felting rates of all three assemblies. It is therefore impossible to predict the effect of a particular treatment on a fabric by applying the same conditions of treatment to the loose wool. A very detailed study of a particular treatment is necessary before loose-wool felting can be used for prediction purposes. [ABSTRACT FROM AUTHOR]
