Salicylic acid (SA) may accelerate the cell death of cadmium-stressed roots to avoid cadmium (Cd) uptake by plants or may play positive roles in protecting the stressed roots from Cd-induced damage. To test these hypotheses, we performed a series of split-root hydroponic experiments with one-half of rice (Oryza sativa L. cv. Jiahua 1) roots exposed to 50 microM Cd and the other half not exposed...

Six new complexes [Cd(tpy)(pfb)2] (1, tpy = 2,2?:6?,2?-terpyridine), [Ln2Cd2(tpy)2(pfb)10] (Ln Eu (2Eu), Tb (2Tb)), [Ln2Cd2(tbtpy)2(pfb)10]·2MeCN (3Eu), (3Tb), tbtpy 4,4?,4?-tri-tert-butyl-2,2?:6?,2?-terpyridine), [Eu2Cd2(tppz)(pfb)10]n (4, tppz 2,3,5,6-tetra-(pyridin-2-yl)pyrazine) based on pentafluorobenzoic acid (Hpfb) have been prepared and investigated. The effect of tridentate ligands geo...

Reactions of Cd(NO(3))(2)·4H(2)O with TabHPF(6) (TabH = 4-(trimethylammonio)benzenethiol) and Et(3)N in the presence of NH(4)SCN and five other N-donor ligands such as 2,2'-bipyridine (2,2'-bipy), phenanthroline (phen), 2,9-dimethyl-1,10-phenanthroline (2,9-dmphen), 2,6-bis(pyrazd-3-yl)pyridine (bppy) and 2,6-bis(3,5-dimethyl-1H-pyrazol-1-yl)pyridine (bdmppy) gave rise to a family of Cd(II)/thi...

Renal function was examined in adult rainbow trout (Oncorhynchus mykiss) after chronic exposure to a sublethal level of dietary Cd (500 mg/kg diet) for 52 d and during a subsequent challenge to waterborne Cd (10 microg/L) for 72 h. Dietary Cd had no major effects on UFR (urine flow rate) and GFR (glomerular filtration rate) but caused increased renal excretion of glucose, protein, and major ion...

The structures of the first two complexes with bidentate coordination aminoguanidine Schiff base, i.e., 2-acetylpyridine-aminoguanidine (L), are reported. complex formula [Cd2Cl6(HL)2] (1) was obtained in reaction warm aqueous solutions chloride salts Cd(II), Zn(II) and ligand, while cadmium bromide ligand presence deprotonating agent as well ammonium thiocyanate resulted formation which base h...

Thymol (THY)/γ-Cyclodextrin(γ-CD) inclusion complex (IC) encapsulated electrospun zein nanofibrous webs (zein-THY/γ-CD-IC-NF) were fabricated as a food packaging material. The formation of THY/γ-CD-IC (1:1 and 2:1) was proved by experimental (X-ray diffraction (XRD), thermal gravimetric analysis (TGA), 1H NMR) and computational techniques. THY/γ-CD-IC (2:1) exhibited higher preservation rate an...

In the binuclear title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(7)N(3)O(2))(2)], the Cd(II) cations are linked by carboxyl-ate O atoms into a four-membered Cd(2)O(2) rhombic ring with a Cd⋯ Cd separation of 3.7515 (5) Å. Each Cd(II) atom is seven-coordinated by a bidentate 5-nitro-1,10-phenanthroline (5-NO(2)-phen) ligand and two bidentate acetate anions, one of which also acts as a bridge link...
