Cui, LiBin, Norberta W. Schoene, Lei Zhu, Jessica C. Fanzo, Ali Alshatwi, and K. Y. Lei. Zinc depletion reduced Egr-1 and HNF-3 expression and apolipoprotein A-I promoter activity in Hep G2 cells. Am J Physiol Cell Physiol 283: C623–C630, 2002. First published April 24, 2002; 10.1152/ ajpcell.00308.2001.—We examined the influence of zinc status on expression of certain transcription factors inv...

Halide, Pyridine Complexes, Zinc, X-Ray Data Zinc dichloride reacts with aminomethylpyridine (AMP) to the corresponding 1:1 adduct 1, whereas ZnBr2 forms an ionic 1:2 complex of the type [(AMP)2ZnBr]+ Br~ 2, which loses one neutral coligand upon heating in M e-C (0)0E t to yield nearly insoluble (AMP)ZnBr2 3. The condensation reaction of these compounds with acetone yields propylideneaminomethy...

A recently reported binuclear zinc hydroxide complex [(L(1)Zn(2))(mu-OH)](ClO(4))(2) (, L(1) = 2,6-bis[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenolate monoanion) containing a single bridging hydroxide was examined for thioester hydrolysis reactivity. Treatment of it with hydroxyphenylthioacetic acid S-methyl ester in dry CD(3)CN results in no reaction after approximately 65 h at 45(1) degr...

Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...

Studies were undertaken to determine the effect of host zinc deficiency upon the distribution of Cd, Zn and Cu between and within male rat kidney cytosol and unfractionated cell pellet. In the first experiment male rates were fed stock diets supplemented with 100 micrograms Cd/mL in the drinking water for 30 days. Then Cd-treated rats and controls were segregated into groups, which received sem...

Zinc signals are utilized by several immune cell receptors. One is TLR4, which causes an increase of free zinc ions (Zn 2+) that is required for the MyD88-dependent expression of inflammatory cytokines. This study investigates the role of Zn 2+ on Toll/IL-1R domain–containing adapter inducing IFN-b (TRIF)–dependent signals, the other major intracellular pathway activated by TLR4. Chelation of Z...

We have designed a unique strategy to obtain a zinc-salen functionalized porous polymer (Zn@SBMMP) with high zinc content (15.3 wt%) by an easy one-step, cost effective and scalable process, which shows unprecedented catalytic efficiency in the CO2 fixation reaction via cycloaddition of CO2 with epoxides. We hypothesize that a high density of Zn-Schiff base/salen units present in the porous pol...

One hundred thirty-four putative Bacillus isolates were recovered from soybean rhizosphere soils of Nimar region to select effective zinc solubilizers for increased assimilation of zinc (Zn) in soybean seeds. These isolates were screened in vitro for zinc-solubilization ability on Tris-minimal agar medium supplemented separately with 0.1% zinc in the form of zinc oxide, zinc phosphate, and zinc...

We examined the influence of zinc status on expression of certain transcription factors involved in regulation of apolipoprotein A-I (apoAI) expression in human hepatoblastoma Hep G2 cells. A low zinc basal medium (zinc deficient, ZD) consisting of DMEM and 10% Chelex100-treated fetal bovine serum was used to deplete cellular zinc over one passage. Cells were also cultured for one passage in me...

BACKGROUND Rates of mental illness in children are increasing throughout the world. Observational studies of depression, anxiety, and attention-deficit hyperactivity disorder suggest that zinc is an alternative treatment. OBJECTIVE We examined the effect of zinc supplementation on the mental health of school-age children in Guatemala. DESIGN From January to October 2006, we conducted a 6-mo...
