Doping of zinc with silver, palladium, and gold was found to increase reactivity towards carbon tetrachloride in water. Commercial zinc dust, cryochemically prepared zinc metal particles (SMAD nanoparticles), and zinc dust pressed into pellets (mechanically activated zinc) were employed. Reduction products detected were methane, ethylene, acetylene, and other hydrocarbons along with products of...

Lead has been shown to produce cognitive and motor deficits in young rats that could be mediated, at least in part, by inhibition of the zinc-containing heme biosynthetic enzyme delta-aminolevulinate dehydratase (ALA-D). In the present study we investigated the effects of lead and/or zinc treatment during the second stage of rapid postnatal brain development on brain, kidney and blood ALA-D spe...

We recently reported a phenotypic association between reduced susceptibility to zinc and methicillin resistance in Staphylococcus aureus CC398 isolates from Danish swine (F. M. Aarestrup, L. M. Cavaco, and H. Hasman, Vet. Microbiol. 142:455-457, 2009). The aim of this study was to identify the genetic determinant causing zinc resistance in CC398 and examine its prevalence in isolates of animal ...

Zinc has been shown to have antioxidant properties and to exhibit inhibitory effects on apoptosis. In this work we investigated the effect of zinc on DNA integrity and on apoptosis of HaCaT keratinocytes. Cells were submitted to zinc deprivation by a diffusible zinc chelator, (N,N,N',N'-tetrakis (2-pyridylmethyl)ethylenediamine) (TPEN) or supplied with zinc chloride and submitted to UVB radiati...

Background: Cobalt (Co) is an essential trace element for mammals required for the synthesis of vitamin B12. It is not a cumulative toxin but chronic exposure induces negative effects on the organism. It was proven that cobalt passes via placenta appearing in the fetal blood and amniotic fluid and it is shown to possess an embryotoxic effect. Also, chromium (Cr) is recognized as a trace element...

Other studies avoided the use of a zinc salt by generating lithium zincates either by iodine-metal exchange 7 or by deprotonation. 8 In 2002, Gauthier and co-workers documented an approach through lithium zincates using only one third equivalent of zinc chloride for the synthesis of 5-aryl-2-furaldehydes from 5-lithio-2-furaldehyde diethyl acetal. 9 In addition, Mutule and Suma described in 200...

BACKGROUND Despite all progresses in surgical science, bleeding caused by traffic accidents is still a challenge for surgeons to save patients' lives. Therefore, introducing an effective method to control external bleeding is an important research priority. OBJECTIVES This study aimed to compare haemostatic effect of zinc chloride and simple suturing to control external bleeding. MATERIALS ...

Mohs melanoma chemosurgery using 50% zinc chloride has not been widely accepted despite a 30-year consecutive series indicating 53% survival improvement (p = .003) for advancedmelanomas over conventional surgery. In chemosurgery, melanomas are fixed and removed in layers with 24-hour zinc chloride paste applications before each excision. An extra application is made to the tumor-free plane to e...
