Four novel mixed metal selenites or tellurites containing PdO(4) squares, namely, BaPd(SeO(3))(2), Bi(2)Pd(SeO(3))(4), and Pb(2)Pd(QO(3))(2)Cl(2) (Q = Se, Te), have been prepared and structurally characterized by single crystal X-ray diffraction analyses. These compounds exhibit three different types of anionic structures. BaPd(SeO(3))(2) contains one-dimensional (1D) [Pd(SeO(3))(2)](2-) anioni...

BACKGROUND The effects of cyclosporine (Cs), a fungal cyclic polypeptide with potent immunosuppressive activity, on fertility have assumed greater significance with the increasing numbers of transplantations being performed all over the world. Current study was undertaken to investigate the potential of Satureja khuzestanica Essential Oil (SEO) as an antioxidant to mitigate Cs-induced reprotoxi...

Four new lead(II) or bismuth(III) selenites and a tellurite, namely, Pb(3)(TeO(3))Cl(4), Pb(3)(SeO(3))(2)Br(2), Pb(2)Cd(3)(SeO(3))(4)I(2)(H(2)O), Pb(2)Ge(SeO(3))(4) and BiFe(SeO(3))(3), have been prepared and structurally characterized by single crystal X-ray diffraction (XRD) analyses. These compounds exhibit five different types of structures. The structure of Pb(3)(TeO(3))Cl(4) features a th...

Sandalwood essential oil (SEO) is extracted from Santalum trees. Although α-santalol, a main constituent of SEO, has been studied as a chemopreventive agent, the genotoxic activity of the whole oil in human breast cell lines is still unknown. The main objective of this study was to assess the cytotoxic and genotoxic effects of SEO in breast adenocarcinoma (MCF-7) and nontumorigenic breast epith...

A facultative bacterium capable of removing the selenium (Se) oxyanions selenate (SeO(inf4)(sup2-)) and selenite (SeO(inf3)(sup2-)) from solution culture in flasks open to the atmosphere was isolated and studied with the goal of assessing its potential for use in bioremediation of seleniferous agricultural drainage water. Elemental Se (Se(sup0)) was confirmed as a product of the reaction. The o...

The trace metal selenium is in demand for health supplements to human and animal nutrition. We studied the reduction of selenite (SeO₃⁻²) to red elemental selenium by Rhodopseudomonas palustris strain N. This strain was cultured in a medium containing SeO₃⁻² and the particles obtained from cultures were analyzed using transmission electron microscopy (TEM), energy dispersive microanalysis (EDX)...

Modified Hbs are being developed as "blood substitutes," but intravascular injection of diaspirin cross-linked Hb (DBBF-Hb) can produce venular leakage. Hb toxicity may arise from reactive oxygen species, so the antioxidant sodium selenite (Na(2)SeO(3)) was used in an attempt to reduce leak formation. In anesthetized Sprague-Dawley rats, one-half of which received 2 x 10(-6) g/ml Na(2)SeO(3) in...

This paper provides an empirical link between the expected cost of equity and firms’ Seasoned Equity Offerings activities, using a novel measure of forward-looking cost of equity. There is a negative impact of expected cost equity on SEO likelihood and amount of proceeds, exists on both market and firm level. Empirical evidence suggests that the negative SEO announcement effect and post-SEO lon...

This paper examines the relation between the Seasoned Equity Offering (SEO) announcement effect and earnings timeliness. I predict that firms with greater earnings timeliness tend to have less information asymmetry between managers and investors, thus decreasing the magnitude of the price drop at the SEO announcement. As anticipated, I find that SEO negative announcement effect varies inversely...
