a b s t r a c t   zinc deficiency in man is characterized by skin lesion, alopecia and has been linked to growth retardation and mental disturbance. for supplementation purposes zinc is currently presented as its sulfate salt, from which uptake by the body is poor, necesseting the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailab...

The three-dimensional structure of a tryptophan-containing variant of the IgG-binding B1 domain of protein L has been solved in two crystal forms to 1.7 and 1.8 A resolution. In one of the crystal forms, the entire N-terminal histidine-tag region was immobilized through the coordination of zinc ions and its structural conformation along with the zinc coordination scheme were determined. However...

The amyloid precursor-like protein 1 (APLP1) is a type I transmembrane protein that plays a role in synaptic adhesion and synaptogenesis. Past investigations indicated that APLP1 is involved in the formation of protein-protein complexes that bridge the junctions between neighboring cells. Nevertheless, APLP1-APLP1 trans interactions have never been directly observed in higher eukaryotic cells. ...

The object of an experiment was inorganic and organic forms of zinc, copper and manganese applied in mineral mixtures to dairy cows. The experiment was carried out on 90 cows with average milk yield for previous lactation of about 9 500 kg milk. The cows received mineral mixtures containing inorganic or organic forms of zinc, copper and manganese for 6 weeks before calving and during the first ...

PURPOSE Manufacturers commonly provide information on the physical properties of dental materials, but information on their antibacterial properties is often missing. This study determined the antibacterial properties of four currently used orthodontic band cements against three different strains of Streptococcus mutans. METHODS The cements utilized were Durelon, Ketac, Mizzy Zinc Phosphate, ...

In this study, we first cloned nlz2, a second zebrafish member of the nlz-related zinc-finger gene family. nlz2 was expressed together with nlz1 in a broad posterior domain during gastrula stages as well as at the midbrain-hindbrain boundary and in the hindbrain caudal to rhombomere 4 during segmentation. nlz2 was also expressed in regions distinct from nlz1, notably in the forebrain, midbrain,...

The results of foliar fertilization spring wheat crops Struna myronivska variety with aqueous solutions zinc, manganese and their chelated analogues in EDTA (zinc complexates) at different stages plant growth development are presented. research was conducted on sodmedium podzolic gley sandy soils Polissia contaminated by radionuclides after the Chernobyl accident. On average, 2014–2016 yy. plan...

Electrochemical biosensors have superior properties over other existing measurement systems because they can provide rapid, simple and low-cost on-field determination of many biological active species and a number of dangerous pollutants. In our work, we suggested a new heavy metal biosensor based on interaction of heavy metal ions (Cd and Zn) with phytochelatin, which was adsorbed on the surfa...

zinc is one of the most important micronutrient with essential role in biochemical regulation of the body functions. the importance of zinc in pregnancy period was widely studied in various countries. variation in zinc plasma levels during pregnancy needs more investigation, because maternal zinc deficiencies may cause some severe abnormalities in the fetus. in this study the plasma levels of z...

background:childhood zinc deficiency is a common problem in many developing countries where people rely mainly on plant based diets with low zinc contents. zinc supplementation is one of strategies to combat zinc deficiency and its consequences in children. the aim of this community trial was to examine the effect of zinc supplementation on the linear growth of children 6-24 months of age and t...
