Publisher: Elsevier

Journal description

The journal provides the reader with a thorough description of theoretical and applied aspects of trace elements in medicine and biology and is devoted to the advancement of scientific knowledge about trace elements. Trace elements play essential roles in the maintenance of physiological processes. During the last decades there has been a great deal of scientific investigation about the function and binding of trace elements. The Journal of Trace Elements in Medicine and Biology focuses on the description and dissemination of scientific results concerning the role of trace elements with respect to their mode of action in health and disease and nutritional importance. Progress in the knowledge of the biological role of trace elements depends, however, on advances in trace elements chemistry. Thus the Journal of Trace Elements in Medicine and Biology will include only those papers that base their results on proven analytical methods.

    ABSTRACT: Background: Zn-deficiency has been associated with numerous alterations during pregnancy including low birth weight; however, the research relating neonatal zinc status and birth weight has not produced reliable results. Objective: To compare the serum Zn-levels of cord blood in healthy newborns and low birth weight newborns, and to assess a possible relationship between zinc concentration and neonatal birth weight and gestational age. Material and methods: 123 newborns divided in “study group” (n = 50) with <2500 g birth weight neonates and “control group” (n = 73) with ≥2500 g birth weight neonates were enrolled. Study group was subdi-vided according to gestational age in preterm (<37 weeks) and full-term (≥37 weeks). Serum cord blood samples were collected and the Zn-levels were analyzed using flame Atomic Absorption Spectropho-tometry method and the result was expressed in �mol/L. The Zn-levels were compared between the groups (Mann–Whitney-U test) and the Zn-levels were correlated with the birth weight and gestational age (Spearman’s rank correlations). Results: Statistically significant low positive correlation between Zn-levels and birth weight (� = 0.283; p = 0.005) was found. No statistically significant difference between Zn-levels of study and control groups [17.00 ± 0.43 vs. 18.16 ± 0.32 (p = 0.053)] was found. Statistically significant low positive correlation between Zn-levels and gestational age (� = 0.351; p = 0.001) was found. No statistically significant dif-ference between Zn-levels of preterm as compare to full-term newborns [16.33 ± 0.42 vs. 18.43 ± 0.93 (p = 0.079)] was found. Zn-level of preterm subgroup was significantly lower compared to control group (p = 0.001). Conclusions: Despite low birth weight preterm neonates had significantly lower serum zinc levels of cord blood than healthy term neonates, the correlation between cord blood zinc levels and birth weight and gestational age was lower. The results are not enough to relate the change in cord blood zinc concentration to the birth weight values or gestational period. In relation to complicated pregnancies, further studies regarding zinc levels in blood in our population are required.

    ABSTRACT: The aim of this study was to examine the association between combined concentrations of macro and trace elements and markers of oxidative stress and antioxidative defense system function together with selected cytokine levels. Based on the combined medians of the seminal plasma levels of calcium, magnesium, zinc, copper, iron, and selenium, the study subjects (88 fertile male volunteers) were divided into the following two subgroups: the Me-L group (low level of metals) and the Me-H group (high level of metals). There was a tendency toward reduced motility in the Me-H group compared to that in the Me-L group. The total protein, albumin, and total oxidation status (TOS) levels were significantly higher in the Me-H group than in the Me-L group. The total superoxide dismutase (SOD), Mn-SOD, and CuZn-SOD, activity in spermatozoa were significantly lower in the Me-H group than in the Me-L group. In seminal plasma, the Mn-SOD activity was significantly higher in the Me-H group, whereas the CuZn-SOD activity was significantly lower. Additionally, the activity levels of glutathione peroxidase (GPx) and glutathione-S-transferase (GST) were lower in the Me-H group. The medians of IL-1β, IL-10, and IL-12 were significantly higher in the Me-H group than in the Me-L group, whereas the medians of IL-2, IL-5, and IL-13 were significantly lower. Higher levels of macro and trace elements in the seminal plasma of fertile males may be associated with decreased motility. Higher levels of the examined metals are associated with elevated oxidative stress accompanied by decreased activities of some of the antioxidant enzymes and increased pro-inflammatory cytokine levels.

    ABSTRACT: Our study aimed to assess the distribution of blood lead level and its relationship to essential elements in preschool children in an urban area of China. A total of 6741 children aged 0- to 6-year-old were recruited. Levels of lead, zinc, copper, iron, calcium, and magnesium in whole blood samples were determined using atomic absorption spectrometry. The mean blood lead level (BLL) and the prevalence of BLL≥10μg/dl (5.26±4.08μg/dl and 6.84%, respectively) increased with age gradually, and there was a gender-difference for blood lead, copper, zinc and iron levels. Compared with the group of children who had BLLs<5μg/dl, the groups of 5≤BLLs<10μg/dl and 10≤BLLs<15μg/dl showed higher blood zinc, iron and magnesium levels, and a lower blood calcium level. A positive correlation of lead with zinc, iron and magnesium, and a negative correlation of lead with calcium were found in the group of children with BLL<5μg/dl. Age- and gender-differences were found when assessing the BLL and intoxication prevalence in preschool children. Metabolic disorder of essential elements was found even with a low level of lead exposure. Copyright © 2014 Elsevier GmbH. All rights reserved.

    ABSTRACT: The International Agency for Research on Cancer (IARC) has concluded that dimethylarsinic acid [(CH3)2AsO(OH), DMA(V)], a main metabolite of inorganic arsenic, is responsible for carcinogenesis in urinary bladder and lung in rodents, and various modes of carcinogenic action have been proposed. One theory concerning the mode of action is that the biotransformation of dimethylarsinous acid [(CH3)2AsOH, DMA(III)] from DMA(V) plays an important role in the carcinogenesis by way of reactive oxygen species (ROS) production. Furthermore, dimethylmonothioarsinic acid [(CH3)2AsS(OH), DMMTA(V)], a metabolite of DMA(V), has also been noted because of its higher toxicity. However, the metabolic mechanisms of formation and disappearance of DMA(III) and DMMTA(V), and their toxicity are not fully understood. Thus, the purpose of the present study was to clarify the mechanism of metabolic formation of DMMTA(V) and DMA(V) from DMA(III). The in vitro transformation of arsenicals by treatment with liver homogenate from rodents and sulfur transferase was detected by HPLC-ICP-MS and HPLC-tandem MS. DMMTA(V) is produced from DMA(III) but not DMA(V) by cellular fractions from mouse liver homogenates and by rhodanese from bovine liver in the presence of thiosulfate, a sulfur donor. Not only DMMTA(V) thus produced but also DMA(III) are re-converted into DMA(V) by an in vitro addition of S9 mix. These findings indicate that the metabolic process not only of DMA(III) to DMA(V) or DMMTA(V) but also of DMMTA(V) to DMA(V) consists of a complicated mode of interaction between monooxygenase including cytochrome P450 (CYP) and/or sulfur transferase.

    ABSTRACT: The present study was undertaken to investigate the effects of maternal lead exposure on expression of P2X7 receptor and synaptophysin in the hippocampus of mice offspring. Lead exposure initiated from beginning of gestation to weaning. Lead acetate administered in drinking solutions was dissolved in distilled deionized water at the concentrations of 0.1%, 0.5% and 1% groups, respectively. On the 21st postnatal day, the Pb levels were also determined by graphite furnace atomic absorption spectrometry. The expression of P2X7 receptor and synaptophysin in hippocampus was examined by immunohistochemistry and Western blotting. The lead levels in blood and hippocampus of all lead exposure groups were significantly higher than that of the control group (P<0.05). Compared with the control group, the expression of P2X7 receptor was increased in lead exposed groups (P<0.05), but the expression of synaptophysin was decreased (P<0.05). The high expression of P2X7 receptor and low expression of synaptophysin in the hippocampus of pups may contribute to the neurotoxicity associated with maternal Pb exposure.

    ABSTRACT: Alzheimer's disease (AD) as a neurodegenerative brain disorder is a devastating pathology leading to disastrous cognitive impairments and dementia, associated with major social and economic costs to society. Iron can catalyze damaging free radical reactions. With age, iron accumulates in brain frontal cortex regions and may contribute to the risk of AD. In this communication, we investigated the age-related brain iron load changes in the frontal cortex of 6- and 12-month-old C57BL/6J (C57) and APPswe/PS1ΔE9 (APP/PS1) double transgenic mouse by using graphite furnace atomic absorption spectrometry (GFAAS) and Perls' reaction. In the present study, we also evaluated the age-related changes of DMT1 and FPN1 by using Western blot and qPCR. We found that compared with 6-month-old APP/PS1 mice and the 12-month-old C57 mice, the 12-month-old APP/PS1 mice had increased iron load in the frontal cortex. The levels of DMT1 were significantly increased and the FPN1 were significantly reduced in the frontal cortex of the 12-month-old APP/PS1 mice than that in the 6-month-old APP/PS1 mice and 12-month-old C57 mice. We conclude that in AD damage occurs in conjunction with iron accumulation, and the brain iron load associated with loss control of the brain iron metabolism related protein DMT1 and FPN1 expressions.

    ABSTRACT: Denmark was previously iodine deficient with regional differences. Moderate iodine deficiency appeared in West Denmark and mild iodine deficiency in East Denmark and also Danish pregnant and breastfeeding women suffered from iodine deficiency. The Danish mandatory iodine fortification of salt was introduced in the year 2000 and has increased iodine intake in the Danish population. However, median urinary iodine concentration in the general population and in pregnant and breastfeeding women is still below the level recommended, corresponding to mild iodine deficiency. Certain characteristics may challenge the evaluation of urinary iodine status in pregnancy and during breastfeeding. This review also addresses methodological challenges related to spot urine sampling conditions and the use of iodine supplement and discusses the use of non-pregnant population groups as a proxy for iodine intake in pregnant women.

    ABSTRACT: The diagnosis of Wilson disease has evolved from the original description of a neurological syndrome by Wilson and other contemporaries at the turn of the 20th century to where we recognize that there is a spectrum of clinical liver and neuropsychiatric disease diagnosed by a combination of clinical and biochemical tests and more recently by molecular genetic analysis. The history of the evolution of the findings that help us establish a diagnosis of Wilson disease are presented in the following brief summary of a century of progress towards this end.

    ABSTRACT: The aim of the present study was to investigate the anti-biofilm activity of biologically synthesized selenium nanoparticles (Se NPs) against the biofilm produced by clinically isolated bacterial strains compared to that of selenium dioxide. Thirty strains of Staphylococcus aureus, Pseudomonas aeruginosa, and Proteus mirabilis were isolated from various specimens of the patients hospitalized in different hospitals (Kerman, Iran). Quantification of the biofilm using microtiter plate assay method introduced 30% of S. aureus, 13% of P. aeruginosa and 17% of P. mirabilis isolates as severely adherent strains. Transmission electron micrograph (TEM) of the purified Se NPs (produced by Bacillus sp. MSh-1) showed individual and spherical nano-structure in the size range of 80-220nm. Obtained results of the biofilm formation revealed that selenium nanoparticles inhibited the biofilm of S. aureus, P. aeruginosa, and P. mirabilis by 42%, 34.3%, and 53.4%, respectively, compared to that of the non-treated samples. Effect of temperature and pH on the biofilm formation in the presence of Se NPs and SeO2 was also evaluated.
