AB  - Background: Multiple sclerosis (MS) is a chronic demyelinating disorder intricately linked to perturbations in
trace element levels. While previous studies have explored circulating trace elements in a limited sample, understanding the impact of demographic and clinical variables on the elemental profile within a larger cohort
remains elusive.
Methods: This study aimed to evaluate essential trace elements (Cr, Mn, Co, Cu, Zn, and Se) in the sera of 215 MS
patients compared to a meticulously matched control group of 100 individuals with similar gender and age. Our
main objective was to identify potential variations in elemental profiles based on demographic and clinical
parameters among MS patients, elucidating the prospective relevance of supplementing specific essential trace
elements.
Results: Data indicated a significant decrease in serum levels of Mn, Co, Zn, and Se, and an increase in Cr in MS
patients compared to controls. These trace elements not only discriminated between MS patients and controls but
also exhibited distinctive capabilities among demographic subgroups. Gender, smoking habits, and age strata
(20–40 years and 41–60 years) revealed discernible variations in elemental profiles between MS patients and
their control counterparts. Se demonstrated the singular ability to stratify cases of extreme MS severity, mild
relapsing-remitting MS (RRMS) and highly severe secondary progressive MS (SPMS). In contrast, Co significantly
differentiated RRMS from primary progressive MS (PPMS), while Cu significantly differentiated SPMS from
PPMS. Additionally, Cu showed a negative correlation with MSSS, while Mn and Zn showed a positive correlation
with EDSS.
Conclusion: These findings underscore a substantive deficiency in Mn, Co, Zn, and Se in the MS cohort, supporting
targeted supplementation with these trace elements. This study provides a comprehensive understanding of the
intricate relationship between essential trace elements and MS, paving the way for further research into
personalized nutritional interventions for this complex neurological disorder.

AB  - With the ever-growing concern for human health and wellbeing, the prenatal period of
development requires special attention since fetuses can be exposed to various metals through the
mother. Therefore, this study explored the status of selected toxic (Pb, Cd, Ni, As, Pt, Ce, Rb, Sr, U)
and essential trace metals (Mn, Co, Cu, Zn, Se) in the umbilical cord (UC) sera, maternal sera, and
placental tissue samples of 92 healthy women with normal pregnancies. A further aim focuses on the
potential transplacental transfer of these trace metals. Based on the obtained levels of investigated
elements in clinical samples, it was observed that all of the trace metals cross the placental barrier
and reach the fetus. Furthermore, statistical analysis revealed significant differences in levels of
toxic Ni, As, Cd, U, Sr, Rb, and essential Mn, Cu, and Zn between all three types of analyzed clinical
samples. Correlation analysis highlighted As to be an element with levels that differed significantly
between all tested samples. Principal component analysis (PCA) was used to enhance these findings.
PCA demonstrated that Cd, Mn, Zn, Rb, Ce, U, and Sr were the most influential trace metals in
distinguishing placenta from maternal and UC serum samples. As, Co, and Cu were responsible for
the clustering of maternal serum samples, and PCA demonstrated that the Pt level in UC sera was
responsible for the clustering of these samples. Overall, the findings of this study could contribute to
a better understanding of transplacental transfer of these trace metals, and shed a light on overall
levels of metal exposure in the population of healthy pregnant women and their fetuses.

AB  - Studies indicate that the soil, water and consequently foodstuffs in Serbia are significantly poor in zinc (Zn), and thus, it is likely that there is a Zn deficiency in the Serbian population. This study examined the Zn status in multiple clinical samples, including body fluids (serum, cerebrospinal fluid), whole blood and Zn-rich solid tissues (thyroid and brain tissue). Differences between sex and age were also considered, and comparative analysis of Zn status with other world populations was performed. Serum samples from a large number of Serbian adults approximately had twofold lower Zn amounts when compared to other populations. A similar trend was obtained for whole blood. Males had significantly higher amounts of Zn in serum, whole blood and thyroid tissue samples than females. Higher amounts of Zn were observed in the group older than 50 years. Importantly, in thyroid and brain tissues, Zn was 10- and 20-fold lower, respectively, than reported in the literature. Our results indicate that the population in Serbia could be considered Zn deficient. Therefore, adequate oral Zn supplementation and/or foodstuff fortification should be considered to prevent the deleterious effects caused by Zn deficiency.

AB  - There are only a few reports examining the impact of oxidative stress in patients with benign and
malignant brain tumors. In this study we investigated whether there are changes in antioxidant
system (AOS) parameters and key trace elements between control, benign and malignant brain
tissues. The study also aimed to examine correlations between the analyzed parameters. The study
enrolled both types of brain tumors, benign tumors (BT) and malignant tumors (MT). The results
were compared with control tissue (CT) without tumor infiltration collected from patients with BT.
The following antioxidant parameters were determined: activities of total, manganese‑containing,
and copper/zinc‑containing superoxide dismutase (TotSOD, MnSOD and CuZnSOD), activities of
catalase, glutathione peroxidase, glutathione S‑transferase, glutathione reductase and acetylcholine
esterase (AChE), the concentrations of glutathione and sulfhydryl groups and of manganese (Mn),
copper (Cu), zinc (Zn), and selenium (Se). BT and MT had altered activities/levels of multiple AOS
parameters as compared to CT, indicating that tumor cells had an altered cell metabolism and changes
in AOS represent adaptive response to increased oxidative stress. Low MnSOD and AChE and high
GST activities were significant for distinguishing between MT and CT. Malignant tissue was also
characterized by lower Mn and Cu concentrations relative to CT and BT. Principal Component Analysis
clearly discriminated BT from CT and MT (PC1, 66.97%), while PC2 clearly discriminated CT from BT
and MT (33.03%). Most correlative relationships were associated with Se in the BT group and Cu in the
MT group. The results of this study reveal differences between the AOS parameters and the essential
trace elements between the analyzed groups. The observed dysregulations show that oxidative stress
could have an important role in disrupting brain homeostasis and its presence in the pathogenesis of
benign and malignant brain tumors.

AB  - This study was aimed to determine reference values (RVs) for the manganese (Mn), copper (Cu), zinc (Zn), and selenium (Se) in the whole blood (B) and serum (S) samples of the Serbian population. Blood specimens were collected from healthy persons (n = 295; women/men ratio = 149/146; mean age: 42 ± 2 years). The RVs were calculated as lower limit (LL) and upper limit (UL) of the 95% confidence interval (CI) and were expressed as percentiles (P) in the range from P2.5 to P97.5. The influences of sex, age, and smoking habits on element profiles were considered. It was found that the contents of B-Cu and S-Cu were higher in women, while the contents of B-Zn and S-Zn were higher in men. Both trace elements were significantly increased in a group of persons above 40 when compared to a younger persons (≤ 40 years). According to smoking habits, increased content was found only for S-Mn in the nonsmoker's group (p < 0.05). Comparing our results to the results reported in other population groups worldwide, the Serbian population had significantly reduced content of Se in both types of samples.

abstract = "This study was aimed to determine reference values (RVs) for the manganese (Mn), copper (Cu), zinc (Zn), and selenium (Se) in the whole blood (B) and serum (S) samples of the Serbian population. Blood specimens were collected from healthy persons (n = 295; women/men ratio = 149/146; mean age: 42 ± 2 years). The RVs were calculated as lower limit (LL) and upper limit (UL) of the 95% confidence interval (CI) and were expressed as percentiles (P) in the range from P2.5 to P97.5. The influences of sex, age, and smoking habits on element profiles were considered. It was found that the contents of B-Cu and S-Cu were higher in women, while the contents of B-Zn and S-Zn were higher in men. Both trace elements were significantly increased in a group of persons above 40 when compared to a younger persons (≤ 40 years). According to smoking habits, increased content was found only for S-Mn in the nonsmoker's group (p < 0.05). Comparing our results to the results reported in other population groups worldwide, the Serbian population had significantly reduced content of Se in both types of samples. This finding could highlight the deficiency of Se in the investigated Serbian population and could contribute to the better understanding of the molecular basis for the increased incidence of thyroid and other diseases in which selenium plays a key role.",

AB  - The pathogenesis of malignant brain tumors (MBTs) should be better understood due to the evident association between prolonged exposure to metals and increased risk of MBTs. The present research aimed to find trace metals that could contribute to the pathogenesis of MBTs. Essential trace elements (Mn, Co, Zn, Cu, Se) and relevant toxic metals (Al, Ni, As, Sr, Cd, Ce, Pt, Pb, U) in the serum, cell fraction (CF), cerebrospinal fluid (CSF) and cancerous tissue (CT) samples of MBT patients were analyzed. The results were compared with sex- and age-matched control groups. For the first time, this research showed that elemental profiles of serum, CF, CSF and CT samples in MBT patients were significantly altered compared to the appropriate controls, as well as that higher contents of trace elements (particularly Mn, Se, and Pb) could be involved in the pathogenesis of MBTs. However, the most noticeable change found was the elevated U content, indicating its considerable role as a major cerebral discriminator of the presence/absence of MBTs. The U/Se ratio could be considered as an appropriate blood marker in diagnostic MBT evaluation. The reported results could contribute to better understanding of the poorly understood pathogenesis of MBTs. Furthermore, the reported results could highlight a molecular basis for the pathophysiological changes caused by the hazardous effects of trace metals on brain homeostasis.

AB  - The background level of lead (Pb) in drinking water in Serbia represents a significant health issue. The aim of study was to examine the content of significant toxic and essential trace metals (Mn, Ni, Cu, Zn, As, Se, Cd, Pb, Th, and U) in the thyroid tissues with diagnosed colloid goiter (CG). Different variables were investigated (sex, age, smoking habits, goiter size, and previous history of any thyroid disease). The study was designed to compare the goiter tissues (GTs) to sex- and age-matched healthy- and malignant-thyroid tissues (HTTs and MTTs, respectively). All trace metals were quantified by inductively coupled plasma mass spectrometry (ICP-MS). The reduced content of essential elements (Mn and Se) and increased content of toxic metals (Pb, Th, and U) were found in GTs compared with HTTs. The increased content of the same toxic metals separated GTs from MTTs, as well as reduced content of Mn and Cd. Our results indicated that Pb acts as the main goitrogen, which could highlight its role in the unknown etiology of CG disease. Pb/Se ratio could be considered as a relevant parameter for the tissue separation of GTs from HTTs and/or MTTs. This research also provides novel data on the effects of metal pollutants on thyroid health hazards.

AB  - BACKGROUND The etiology of papillary thyroid carcinoma (PTC) is unknown and some literature data support the hypothesis that heavy metals, as endocrine disrupters, could play a major role in the pathogenesis of thyroid cancer. This study aimed to estimate the content of selected toxic and essential trace metals (Mn, Co, Ni, Cu, Zn, As, Se, Cd, Pb, Th, and U), as well as the selected ratio’s (Cu/Zn and Cd/Se) in the malignant thyroid tissues according to sex, age, smoking habits, familial history of any thyroid disease, pathohistological (PH) types of PTC, tumor size, the existence of a thyroid capsular invasion, intrathyroid tumor dissemination, retrosternal thyroid growth, and TNM progress of PTC. METHODS The study included 66 patients with PTC (women/men ratio = 46/20, mean age: 54 ± 14 years). A comparative analysis was made by collecting the healthy thyroid tissues (HTTs) of the same patients, making the total number of samples 132. All trace metals were quantified by inductively coupled plasma-mass spectrometry (ICP-MS). RESULTS Metals that significantly separated papillary thyroid tissues (PTTs) from the HTTs were Cd, U and Se (p < 0.05). The obtained negative correlation between Cd and Se in the PTTs could explain extrusion of essential Se caused by increased content of Cd. Only Cd had an influence on the retrosternal thyroid growth, while the essential metals (Mn, Co, and Zn) had an influence on thyroid capsular invasion. CONCLUSION It was found that Cd act as the main endocrine disrupter, which could highlight its role in the etiology of PTC. Considering that the Cd/Se ratio significantly separated two studied groups and had an influence on the retrosternal thyroid growth, its altered content could contribute to the better understanding of the molecular basis for pathophysiological changes in the PTC.

AB  - Evaluation of trace metals at level of solid tissue can provide better information than blood or urine and, therefore, could highlight the role of metals in the etiology of organ-specific disease. The current study aimed to establish the baseline content of four essential (Mn, Cu, Zn, Se) and four toxic metals (As, Cd, Pb, U) in the healthy thyroid tissues (HTTs) by considering sex, age and smoking habits. A further aim was to examine whether differences in the content of metals exist in regard to the thyroid diseases, such as benign tumor (BT), Hashimoto's thyroiditis (HT), multinodular goiter (MNG) and thyroid cancer (TC). A total number of investigated tissue samples were 423. All metals were quantified by inductively coupled plasma-mass spectrometry (ICP-MS). It was found that the content of Cu and U was higher in HTTs of women, while the content of Zn was higher in HTTs of men. Increased content of Zn and decreased content of U was found in the group of HTTs above 50 years compared to a younger group (<50 years). Increased content of Cd, Pb and U distinguish smokers from the non-smokers. In comparison with other population groups worldwide, investigated Serbian population had up to 15 times reduced content of Se. Despite the difference in metal's profile according to biological variables, this study also demonstrated, for the first time, that each thyroid disease has its unique metal's profile. The most altered metal's content was found in tissues with HT. Contrarily, the greatest similarity in metal's content with HTTs was found in BT tissues. Based on the increased content, metal's that dominantly discriminated HTTs from the HT, MNG and TC was As, Pb and Cd, respectively. Reported results could highlight the role of toxic and essential trace metals in the not very well clarified etiology of thyroid diseases and, moreover, could provide a molecular basis for pathophysiological changes of metal's hazardous effects on thyroid health at the tissue level.

AB  - Pollution caused by heavy metals affects all forms of life. The aim of the study was to determine the content of toxic (Sr, Ni, Pb, V, Cd, U, Rb, As) and essential (Na, K, Ca, Mg, Zn, Cu, Se, Mn, Cr, Mo, Co) metals in the bone and whole blood samples, in regard to clinical means of long- and short-term exposure, respectively. For this purpose, the cortical and trabecular parts of femoral neck, as well as the blood samples, were collected to quantify bone-important metals by inductively coupled plasma (ICP)-based techniques. According to principal component analysis (PCA), the most influential metal discriminating blood samples was Cu, while all other quantified elements were present in higher amounts in the bones. Additionally, trabecular bones (TBs) could be characterized by higher content of Mo, Cr, V, Mn, Co, As, and Ni compared to cortical bones (CBs). Linear discrimination analysis (LDA) was successfully applied to distinguish trabecular bone from the cortical bone. Significant correlation between essential Ca and toxic Sr with other elements was found and discussed. This study provides novel data on the effects of metal pollutants on bone health hazards. The results obtained for investigating metals may serve as a baseline for further clinical investigations in the orthopedic fields.

abstract = "Pollution caused by heavy metals affects all forms of life. The aim of the study was to determine the content of toxic (Sr, Ni, Pb, V, Cd, U, Rb, As) and essential (Na, K, Ca, Mg, Zn, Cu, Se, Mn, Cr, Mo, Co) metals in the bone and whole blood samples, in regard to clinical means of long- and short-term exposure, respectively. For this purpose, the cortical and trabecular parts of femoral neck, as well as the blood samples, were collected to quantify bone-important metals by inductively coupled plasma (ICP)-based techniques. According to principal component analysis (PCA), the most influential metal discriminating blood samples was Cu, while all other quantified elements were present in higher amounts in the bones. Additionally, trabecular bones (TBs) could be characterized by higher content of Mo, Cr, V, Mn, Co, As, and Ni compared to cortical bones (CBs). Linear discrimination analysis (LDA) was successfully applied to distinguish trabecular bone from the cortical bone. Significant correlation between essential Ca and toxic Sr with other elements was found and discussed. This study provides novel data on the effects of metal pollutants on bone health hazards. The results obtained for investigating metals may serve as a baseline for further clinical investigations in the orthopedic fields.",

AB  - The purpose of this study was to establish reference values (RVs) for the occupationally- and environmentally-important toxic elements in the whole blood of adult Serbian population for the first time. Contaminated drinking water with arsenic, high share of smokers in the country, removing tetraethyl lead from the gasoline and war attack at the end of the twentieth century were some of the reasons to provide background information for arsenic (As), cadmium (Cd), lead (Pb), thorium (Th), and uranium (U) in the blood of the Serbian population. The whole blood samples were collected from the healthy respondents living in the Belgrade and surrounding areas of the capital (n = 305; w/m ratio = 154/151; mean age: 41 ± 2). The concentrations of toxic metals were determined by inductively coupled plasma-mass spectrometry (ICP-MS). Reference values were estimated as the lower limit (LL) and upper limit (UL) of the 95% confidence interval (CI), together with the selected percentiles (P2.5-P97.5). The obtained geometric mean (GM) for As, Cd, Pb, Th, and U were: 0.50 ng/g, 0.32 ng/g, 20.94 ng/g, 0.30 ng/g, and 0.06 ng/g, respectively. The influences of age, sex and lifestyle on results were considered. Women have significantly higher levels of Cd and Th than men. The increased level of Th was observed in the aged group below 40 years, while smokers had significantly higher levels of Pb and double higher level of Cd in the blood than non-smokers (p < 0.05). In comparison with other population groups worldwide, the Serbian population had significantly higher levels of Th and U (up to 100 times higher). These findings could contribute to better understanding of the molecular basis for the development of various health hazards, including the increased incidence of cancer among the Serbian population which need be confirmed by clinical studies.
