OBJECTIVE: Wide variation exists in ovarian cancer incidence rates suggesting the importance of environmental factors. Due to increasing environmental pollution, trace elements and heavy metals have drawn attention in studies defining the etiology of cancer, but scant data is available for ovarian cancer. Our aim was to compare the tissue concentrations of lead, selenium and nickel in epithelial ovarian cancer, borderline tumor and healthy ovarian tissues. METHODS: The levels of lead, selenium and nickel were estimated using atomic absorption spectrophotometry in formalin-fixed paraffin-embedded tissue samples...

Suicide is a major public health concern affecting both the society and family life. There are data indicating that higher level lithium intake with drinking water is associated with lower suicide rate. This pilot study examined the relationship between lithium levels in drinking water and suicide rates in Lithuania. Twenty-two samples from public drinking water systems were taken in 9 cities of Lithuania. The lithium concentration in these samples was determined by inductively coupled plasma mass spectrometry (ICP-MS)...

The etiology and pathophysiology of schizophrenia (SCZ) remain obscure. This study explored the associations between SCZ risk and serum levels of 39 macro and trace elements (MTE). A 1:1 matched case-control study was conducted among 114 schizophrenia patients and 114 healthy controls matched by age, sex and region. Blood samples were collected to determine the concentrations of 39 MTE by ICP-AES and ICP-MS. Both supervised learning methods and classical statistical testing were used to uncover the difference of MTE levels between cases and controls...

Pre-eclampsia is a hypertensive disorder that is associated with adverse maternal and perinatal outcomes. It has been proposed that specific trace and macro elements associated with antioxidant activities may also play a contributory role in aetiology of pre-eclampsia. The aim of this study was to measure the concentrations of thirteen different elements in hair and serum samples from women with a diagnosis of pre-eclampsia and compare them with normotensive controls. Venous blood and pubic hair samples were collected from forty-three pre-eclamptic and twenty-three normotensive pregnant women...

REVIEW
Harry Robberecht, Tess De Bruyne, Nina Hermans
Influences of minerals, oligo- and trace elements on the concentration of biomarkers of the metabolic syndrome (MetS) are reviewed. Since food is a complex mixture of caloric compounds and essential non-caloric food components with multiple interactions and varying bioavailability, it is hard to separate or identify the effect of one single component in a total meal or diet. Moreover the diet contains various non-nutritive biologically active components, which may add some beneficial characteristics. Therefore, conclusions on the effect of components on various biomarkers of MetS are sometimes quite contradictory...

REVIEW
Emilio Carpenè, Giulia Andreani, Gloria Isani
The role of trace elements in animal health has attracted increasing interest in recent years. The essentiality and toxicity of these elements have been extensively investigated in humans, laboratory animal models and partially in domestic animals, whereas little is known about trace element metabolism in most living organisms. Forty years ago our research started on Cd metabolism in molluscs, thereafter expanding to Zn, Cu, and Fe metabolism in many unconventional animal species of veterinary interest. This review summarizes the main results obtained over this long period of time: some of the findings are original and have not been published to date...

In Spain, recently, the public institutions have given information to the population in relation to fish consumption and the risk that it poses to health from the ingestion of mercury supposedly contained in the fish. At the same time, several scientific societies have published various works in this direction. All this without there being, up to now, any study on the evaluation of a probabilistic risk from mercury due to fish and seafood intake in Spain, which is the objective of this present work. For that purpose, we took individual data from a survey of the total diet of 3000 people, whose consumption of the principal fish and seafood species (49) was estimated...

This study aimed to investigate the role of iron, used as a catalyst, in the biological response to pristine and functionalized multi-walled carbon nanotubes (p/fMWCNTs) with an iron content of 2.5-2.8%. Preliminarily, we assessed the pro-oxidant activity of MWCNTs-associated iron by an abiotic test. To evaluate iron bioavailability, we measured intracellular redox-active iron in A549 cells exposed to both MWCNT suspensions and to the cell medium preconditioned by MWCNTs, in order to assess the iron dissolution rate under physiological conditions...

Copper metabolism disturbances in mammary gland (MG) cells have severe consequences in newborns. The mechanism that controls the balance of copper in the MG has not been thoroughly characterized. Four primary copper homeostasis genes in mammals: (1) ceruloplasmin (Cp) encoding multifunction multicopper blue (ferr)oxidase; (2) CTR1 encoding high affinity copper importer 1; and (3 and 4) two similar genes encoding Cu(I)/Cu(II)-ATPases P1 type (ATP7A and ATP7B) responsible for copper efflux from the cells and metallation of cuproenzymes formed in the Golgi complex are expressed in MG...

INTRODUCTION: Hair samples are used as a tool to evaluate environmental exposure to contaminants and metabolic status in the individual. However, the use of human hair is controversial, mainly because of the lack of well-defined reference levels. In the case of Spain, very few biomonitoring studies have investigated these issues in infants, children or adolescents. OBJECTIVE: To establish reference levels for trace elements in children and teenagers in Madrid, Spain...
