1. To investigate the influence of hormonal conditions upon the kinetics of zinc transport, specific radioactivity of 65Zn was determined in certain tissues and fluids from unmated or pregnant rabbits during the first half of gestation. 2. Compartmental analysis was used to find the simplest mathematical model that simulated satisfactorily tracer behaviour. Models were fitted to experimental results by a numerical procedure using a computer. 3. The kinetics of zinc exchange in most tissues investigated could adequately be described by a three-compartment model, in which total tissue zinc content was divided into a rapidly exchanging pool, with a turnover time of about 1h, and a slowly exchanging pool, the turnover time of which was in liver 15h, in peak-stage corpus luteum 8h, and in the other tissues 30-70h. 4. In rabbit endometrium zinc transport varied with hormonal conditions, the turnover rate being higher in non-pregnant than pregnant endometrium. 5. Uptake of 65Zn by uterine fluid was ...

Nearly normal secondary tetanus antitoxin responses were produced by young adult female mice subjected to 600 rads of 60Co gamma whole-body radiation 4 days after secondary antigenic stimulation via the hind leg footpads. In an attempt to correlate the rapid transition from radiosensitivity of the antibody-forming system on day 3 to relative radioresistance on day 4 after booster, we carried out studies on cytokinetics in regional (popliteal) lymph nodes and on incorporation of 3H-l-histidine into circulating antitoxin. Analyses of tritium radioactivity in antigen-antibody precipitates of pooled sera 2 hr after i.v. injection of the labeled amino acid revealed maximum incorporation into antibody around day 7 after booster in nonirradiated controls, and around day 12, i.e., 8 days after radiation, in experimental mice, respectively. Relative radioresistance of the antibody-forming system on day 4 after booster, as opposed to day 3, was attributed to the finding that plasmacellular proliferation ...
tion linkages. For example, increasing maize production stimulates growth in down- stream food processing while also reducing food prices and increasing real incomes that are then spent on nonagricultural commodities. Overall GDP increases by MZN1,227 million, which means that for every MZN1.00 increase in agricultural GDP driven by maize-led growth, there is an additional MZN0.42 increase in nonagricultural GDP (that is, a growth-linkage ratio of 1.42). Comparing these ratios across model scenarios suggests that, even though livestock-led growth con- tributes less to agricultural growth in the Agriculture scenario (see Figure 12.3), it is more effective at stimulating nonagricultural growth than is growth driven by traditional export crops. The latter has weaker economywide growth linkages, because most of these crops are exported directly as raw materials and do not gener- ate many downstream employment opportunities ...

New strategies are needed to address the current and future shortages of radioisotopes that threaten medical research and treatment.
Evidence suggests that New Zealand (NZ) children are mildly zinc deficient and may respond to dietary change. A 20-wk randomized intervention trial was therefore conducted to determine whether an increased intake of red meat or consumption of a fortified manufactured toddler milk drink (FTMD, fortified with zinc and other micronutrients) would increase dietary zinc intakes and improve the biochemical zinc status of 12- to 20-mo-old NZ toddlers. Toddlers were randomized to a red meat intervention (n = 90), FTMD intervention (n = 45), or nonfortified milk placebo (n = 90). Study foods were provided. Adherence was assessed via monthly 7-d meat or milk recording diaries. Hair and serum zinc concentrations, and length and weight were measured at baseline and postintervention. Nutrient intakes were assessed via 3-d weighed food records at baseline, wk 4, and wk 18. At baseline, 38% of participants had low serum zinc concentrations despite seemingly adequate dietary zinc intakes (,4% below the ...
LIM domains are Zn-binding arrays found in a number of proteins involved in the control of cell differentiation, including several developmentally regulated transcription factors and a human proto-oncogene product. The rat cysteine-rich intestinal protein, CRIP, is a 76-residue polypeptide which contains a LIM motif. The solution structure of CRIP has been determined by homonuclear and 1H-15N heteronuclear correlated nuclear magnetic resonance spectroscopy. Structures with individual distance violations of < or = 0.03 angstrom and penalties (squared sum of distance violations) of < or = 0.06 angstrom2 were generated with a total of 500 nuclear Overhauser effect (NOE)-derived distance restraints (averaging 15.6 restraints per refined residue). Superposition of backbone heavy atoms of ordered residues relative to mean atom positions is achieved with pairwise rms deviations of 0.54(+/-0.14) angstrom. As observed previously for a peptide with the sequence of the C-terminal LIM domain from the avian ...

This study was conducted to measure the transport of zinc (Zn) into a pig intestinal brush border membrane vesicle (BBMV) preparation using a radiolabeled Zn-proteinate. Fresh samples of duodenum, jejunum and ileum were obtained from the small intestine of five crossbred weanling pigs to produce the BBMV. We anticipated that the large molecular size of an organic Zn compound would considerably limit or prevent the uptake of Zn by intestinal vesicles when the normal processes of digestion have been bypassed. For that reason, we performed an in vitro procedure designed to simulate the digestive system of the pig (Liu et al., 1998; Tsunoda et al., 2001). Our initial trials using non-radiolabeled Zn with a cellulose carrier determined effective digestion of Zn with a sample size of 0.25 g. Based on these results, this in vitro method was used to digest 0.25 g of 65Zn-proteinate prior to performing uptake studies. We used concentrations of 480 and 960 ppm Zn as Zn-proteinate. 65Zn uptake was allowed ...

An important additional and evolving use of radioisotopes is in the treatment of disease.. There is a fundamental belief that cancer, leukemia, heart disease, Parkinsons disease, and more can be treated-and possibly cured-through the use of molecules that seek and attach radioisotopes to tumors and cancerous growths. Through this process, radioactivity can be delivered directly to the cells that require treatment, with minimal damage to nearby tissue.. NorthStar is well-positioned to meet the challenges ahead.. ...

Zinc absorption in the small intestine is one of the main mechanisms regulating the systemic homeostasis of this essential trace element. This review summarizes the key aspects of human zinc homeostasis and distribution. In particular, current knowledge on human intestinal zinc absorption and the influence of diet-derived factors on bioaccessibility and bioavailability as well as intrinsic luminal and basolateral factors with an impact on zinc uptake are discussed. Their investigation is increasingly performed using in vitro cellular intestinal models, which are continually being refined and keep gaining importance for studying zinc uptake and transport via the human intestinal epithelium. The vast majority of these models is based on the human intestinal cell line Caco-2 in combination with other relevant components of the intestinal epithelium, such as mucin-secreting goblet cells and in vitro digestion models, and applying improved compositions of apical and basolateral media to mimic the in ...

Thermodynamic, viscous and structural properties of melts and glasses in the AlCl3-ZnCl2 system have been investigated. The two pure components are fundamentally different in the molten state. Both metal atoms are four coordinated, however, ZnCl2 forms a corner sharing tetrahedral network whereas AlCl3 is a dimer, Al2Cl6. ZnCl2 is one of two known single component halide glass formers and additions of AlCl3 have shown to form stable glasses. The glass forming ability remains far into the binary AlCl3-ZnCl2 system.The phase diagram of the AlCl3-ZnCl2 system has been investigated by differential thermal analysis. The system is a simple eutectic system, and the eutectic point was observed at 116±2°C and 0.52±0.05 mole fraction ZnCl2. The system is highly glass forming in the range from pure ZnCl2 up to about 0.46 mole fraction ZnCl2. Glass transition temperatures measured by differential scanning calorimetry (heating rate 10 K/min) were recorded from 115°C for pure ZnCl2 to -5.5°C for 0.46 ...

The formation of complex organs from individual tissues is an essential developmental process that requires coordination of many different types of cellular events. Extensive cell-cell contact and communication ensures that these events are well orchestrated. The Drosophila gonad is an ideal model for studying organogenesis. Formation of this organ requires that germ cells and somatic gonadal precursors (SGPs), which are initially specified far apart from each other, undergo a complex morphogenetic program to form a properly patterned embryonic gonad. This organ then further differentiates into either an ovary or testis.. Germ cells are initially formed at the posterior pole of Drosophila embryos during the syncytial blastoderm stage. They are carried inside the embryo during gastrulation, where they migrate through the midgut epithelium into the mesoderm to contact SGPs (reviewed by Starz-Gaiano and Lehmann, 2001). SGPs are specified in bilateral clusters within three parasegments of the embryo ...

Groups of 50 male and 50 female rats were fed diets containing varying levels of dietary zinc [3.5, 7, 38 (control), 250, or 500 ppm] for 104 to 106 weeks. The 3.5 and 7 ppm diets were considered to be zinc deficient, the control diet of 38 ppm was considered to be zinc sufficient, and the 250 and 500 ppm dietary zinc concentrations represented diets with excess zinc. Dietary concentrations of 3.5, 7, 38, 250, and 500 ppm resulted in average daily intakes of 0.1, 0.3, 1.4, 8.7, and 17.6 mg dietary zinc/kg body weight to males and 0.1, 0.3, 1.5, 9.9, and 19.9 mg/kg to females. Ten male and 10 female additional special study rats were exposed to the same concentrations for 53 weeks and used for micronuclei evaluations, comet assays, hematology, and trace metal concentration determinations.. There were no chemical-related effects on survival. However, male rats maintained on the 3.5 ppm zinc-deficient diet had an increased survival rate compared to the controls that was likely due to low survival ...

Recently, there has been considerable interest in the use of terrestrial plants as a green technology for the remediation of surface soils contaminated with toxic heavy metals. This technology, termed phytoremediation, uses plants to extract heavy metals from the soil and to concentrate them in the harvestable shoot tissue (1, 2). A major factor behind the interest in phytoremediation of metal-polluted soils has been the growing awareness of the existence of a number of metal-accumulating plant species. These plant species, called hyperaccumulators, are endemic to metalliferous soils and can accumulate and tolerate high levels of heavy metals in the shoot (3, 4). Among the best known hyperaccumulators is Thlaspi caerulescens. This member of the Brassicaceae family has attracted the interest of plant biologists for over a century because of its ability to colonize calamine and serpentine soils containing naturally elevated levels of heavy metals such as Zn, Pb, Cd, Ni, Cr, and Co. Certain ...

... and zinc in chicken The purpose of this study was to investigate the effect of dietary supplementation with different levels of copper and zinc on the production performance and copper and zinc excretion of laying hens. A total of 288 Hy-Line W36 birds, during from 24 to 27 weeks age the hen-day production above 90% of birds. The results showed that the different copper levels of diet did not affect the egg weight, hen-day production, feed intake and feed conversion ratio. The laying hens of intake Cu-10 diet had significantly thicker eggshell thickness, smaller egg mass and eggshell breaking strength than intake Cu-0 diet birds. Laying hens of intake Zn-90 diet had significantly higher fecal excretion than birds of intake Zn-30 diet. However, the Cu and Zn concentration in feces was increased along with Cu and Zn intake increased.. (T. M. Su, S. M. Liou,Y. H. Weng, T. H. Hsiao and H. F.Lee ...
Studies have evidenced that zinc metabolism is altered in presence of Down syndrome, and zinc seems to have a relationship with the metabolic alterations usually present in this syndrome. In this work, the Zn-related nutritional status of adolescents with Down syndrome was evaluated by means of biochemical parameters and diet. A case-control study was performed in a group of adolescents with Down syndrome (n = 30) and a control group (n = 32), of both sexes, aged 10 to 19 years. Diet evaluation was accomplished by using a 3-day dietary record, and the analysis was performed by the NutWin program, version 1.5. Antropometric measurements were performed for evaluation of body composition. The Zn-related nutritional status of the groups was evaluated by means of zinc concentration determinations in plasma and erythrocytes, and 24-h urinary zinc excretion, by using the method of atomic absorption spectroscopy. The diet of both groups presented adequate concentrations of lipids, proteins, ...
