Zn is an essential micronutrient and an important ionic signal whose excess, as well as scarcity, is detrimental to cells. Free cytoplasmic Zn is controlled by a network of Zn transporters and chelating proteins. Recently, lysosomes became the focus of studies in Zn transport, as they were shown to play a role in Zn-induced toxicity by serving as Zn sinks that absorb Zn from the cytoplasm. Here...

a r t i c l e i n f o Zn–Ni, Zn–Co and Zn–Ni–Co coatings were electrodeposited on mild steel from an acidic chloride bath containing p-aminobenzenesulphonic acid (SA) and gelatin. These additives changed the phase content in the coatings, most likely as a result of their adsorption at the surface of the cathode. The effect of gelatin was more pronounced than that of SA. The Faradaic efficiency ...

This study examines the food-chain transfer of Zn from two plant species, Urtica 31 dioica (stinging nettle) and Acer pseudoplatanus (sycamore maple), into their corresponding 32 aphid species, Microlophium carnosum and Drepanosiphum platanoidis. The plants were 33 grown in a hydroponic system using solutions with increasing concentrations of Zn from 0.017 34 to 42 mg Zn/l, although U. dioica o...

Two 28-d randomized complete block design experiments were conducted to evaluate the effects of concentrations and sources of Zn on growth performance of nursery pigs. Seven stations participated in Exp. 1, which evaluated the efficacy of replacing 2,500 ppm of Zn from ZnO with 125, 250, or 500 ppm of Zn from Zn methionine. A control diet with 125 ppm of supplemental Zn was included at all stat...

Zinc is the trace element involved in more biological functions than any other micromineral in the nutrition of the newly weaned pig. Its role in growth via protein synthesis and antioxidant defense makes it a key nutrient in the diet of the newly weaned nursery pig for maximum lean tissue growth and health. In this study, 500 pigs (5 pigs/pen) were weaned at approximately 18 d of age and fed 0...
