AB  - The purpose of this study was to examine the impact of low doses of lead (Pb) on levels of thyroid hormones (T3, T4, FT3, and FT4) and thyroid-related antibodies (anti-Tg and anti-TPO) in the rat model, as well as genes that are related to Pb and thyroid function, relationships between genes, biological processes, molecular processes, and pathways using an in silico approach. Male rats were randomized into seven groups (n = 42), one control group and six groups that received a range of Pb doses: 0.1, 0.5, 1, 3, 7, and 15 mg Pb/kg body weight (b.w.). Dose-response modelling was performed by PROAST software using model averaging method. The Comparative Toxicogenomics Database, GeneMANIA server, and ToppGene Suite portal were used as the main bioinformatic tools in this analysis. The results of our study have shown that low Pb doses induced elevation of thyroid hormones (T4, FT4, and TSH) in rats after subacute exposure, while had no impact on T3, FT3, anti-TPO, and anti-Tg, indicating hyperthyroidism. Dose-dependent effects were increases in T4 and FT4, with the lowest benchmark dose derived for FT4 levels. In silico toxicogenomic data analysis showed that the main molecular pathways/process related to Pb-induced hyperthyroidism are connected with 14 genes involved in antioxidant defense and Se-dependent processes. The results presented here may be useful in further investigation of the health impacts of low-level Pb exposure on thyroid function and endocrine disruption effects.

AB  - The current study aimed to examine the effect of toxic metal(oid) mixtures (lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg), cadmium (Cd), chromium (Cr), and nickel (Ni)) on female reproductive function in Wistar rats after the 28- and 90-day exposure to dose levels calculated on the basis of the previously conducted human study. Experimental groups included: 2 controls (28- and 90-day), treated groups - doses based on: median– F2 (28) and F2(90) and 95th percentile concentrations in the general human population – F3(28) and F3(90); calculated lower Benchmark dose confidence limit (BMDL) for effects on hormone levels – F1(28) and F1(90) and a group given the doses calculated on the basis of the reference values from the literature (F4(28)). Blood and ovarian samples were collected for sex hormones and ovary redox status analysis. After 28-day exposure, changes were present both in prooxidants and antioxidants. However, after the 90-day exposure redox status imbalance was majorly caused by the disturbance of antioxidants. Changes in some parameters were observed even after exposure to the lowest doses. After 28-day exposure, the strongest dose-response relationship was found between hormones: LH and FSH and toxic metal(oid)s and, after 90-day exposure, between investigated redox status parameters: sulfhydryl groups, ischemia-modified albumin and nuclear factor erythroid 2–related factor 2 (Nrf2) and toxic metal(oid)s. Low obtained BMDLs and narrow Benchmark intervals for toxic metal(oid)s and some of the parameters might confirm the “no-threshold” paradigm. This study indicates possible detrimental effects of prolonged exposure to real-life mixtures of toxic metal(oid) on female reproductive function.

AB  - Testis cancer (TC) is the most common malignancy of young men. Current evidence from studies, alongside genetics and hormonal status, suggests a significant role of toxic metals, cadmium (Cd) and lead (Pb), in the origin and development of TC. Besides oxidative stress and endocrine disruption, interaction with bioelements is one of the critical mechanisms of Cd and Pb toxicity and malign transformation. This study aimed to investigate metal levels in blood, healthy, and tumor testis tissue and to reveal hormone, oxidative status, and bioelements levels in patients with TC. The study enrolled 52 patients with TC and 61 healthy volunteers. Toxic metals and bioelements levels were analyzed by atomic absorption spectrophotometry (AAS) while electrochemiluminescence immunoassay (ECLIA) and spectrophotometry methods were used for hormone and oxidative parameters evaluation. Significantly higher blood Cd levels were depicted in TC cohort. Furthermore, blood Cd elevation was associated with a 1.98 higher probability of TC developing. However, a metal concentration between healthy and tumor testis tissue did not differ significantly. Lower levels of estradiol and testosterone, established in a cohort of TC patients, followed the significant role of hormones in TC development. At the same time, ischemia-modified albumin (IMA) has been recognized as a parameter with very good accuracy as a potential diagnostic marker for TC. The study revealed different distribution patterns of copper (Cu) and zinc (Zn) in the three compartments of the patients, as well significant correlation between essential metals Cu/Zn and toxic metals Cd/Pb indicating metal-metal interactions as pivotal mechanisms of metals toxicity.

AB  - Recent data indicate that lead (Pb) can induce adverse effects even at low exposure levels. Moreover, the corresponding mechanisms of low Pb toxicity have not been well identified. In the liver and the kidneys, Pb was found to induce various toxic mechanisms leading to organ physiological disruption. Therefore, the purpose of the study was to simulate low-dose Pb exposure in an animal model with the aim of assessing oxidative status and essential element levels as the main mechanism of Pb toxicity in the liver and kidneys. Furthermore, dose–response modelling was performed in order to determine the benchmark dose (BMD). Forty-two male Wistar rats were divided into seven groups: one control group, and six groups treated for 28 days with 0.1, 0.5, 1, 3, 7, and 15 mg Pb/kg b.w./day, respectively. Oxidative status parameters (superoxide dismutase activity (SOD), superoxide anion radical (O2−), malondialdehyde (MDA), total sulfhydryl groups (SHG), and advanced oxidation protein products (AOPP)) and Pb, copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) levels were measured. Lowering Cu levels (BMD: 2.7 ng/kg b.w./day), raising AOPP levels (BMD: 0.25 µg/kg b.w./day) in the liver, and inhibiting SOD (BMD: 1.3 ng/kg b.w./day) in the kidneys appear to be the main mechanisms of Pb toxicity. The lowest BMD was derived for a decrease in Cu levels in liver, indicating that this effect is the most sensitive.

AB  - The objectives of the study were to simulate low-level Pb exposure scenario in an animal model and to examine reproductive adverse effects. Based on obtained data, we have performed Benchmark dose (BMD)-response modelling. Male Wistar rats were randomized in seven groups (n = 6): one control and six treated with: 0.1, 0.5, 1, 3, 7, and 15 mg Pb/kg body weight, daily for 28 days by oral gavage. The rats were sacrificed and the blood and testes were used for further analysis of testosterone levels in serum, testicular essential metal levels and histological analysis. The Pb treatment led to a dose-dependent decrease of serum testosterone levels with a negative trend (BMDI 0.17–6.13 mg Pb/kg). Increase of Zn (dose-dependent, BMDI 0.004–19.7 mg Pb/kg) and Cu and a decrease of Mn testicular levels were also detected with unscathed histology of the testes. The presented results might be used in further evaluation of the point of departure in human health risk assessment for Pb.

AB  - With global urbanization and industrialization, air pollution has become an inevitable problem. Among air pollutants, toxic metals bound to particulate matter (PM) have a high hazardous potential, contributing to the development of several diseases, including various types of cancer. Due to PM pollution, Serbia is considered to be among the most polluted countries in Europe. Therefore, the objective of the study was to assess and characterize the non-carcinogenic and carcinogenic risks of children’s and adults’ exposure to metal(oid)s (Pb, Cd, Ni, and As) bound to PM10 in five of the most polluted areas in the Republic of Serbia (Subotica, Smederevo, Bor, Valjevo, and Kraljevo). Non-carcinogenic (HQ and HI) and carcinogenic risk (CR) were calculated using USEPA methodology. Our results show that PM10 concentrations exceeded the annual limit of 40 μg/m3 at four out of five monitoring sites (ranging from 44.33 to 63.25 μg/m3). Results obtained from Bor monitoring station show that safe limits were exceeded for both children and adults, indicating an unacceptable risk (> 1) obtained for inhalation exposure to the As (HQ = 6.14) and Cd (HQ = 1.17), while total HI was 7.43, which characterized the risk as unacceptable. For the same station, the CR value was 1.44E−04 (> 1 × 10−4). In other sites, the risks were acceptable. The characterized risk from exposure to the toxic elements via PM10 in critical locations in Serbia contributes to improving air quality by requiring regulatory organs to take new actions and adopt new measures to reduce air pollution.

AB  - Sulforaphane (SFN) is a naturally occurring molecule present in plants from Brassica family. It becomes bioactive after hydrolytic reaction mediated by myrosinase or human gastrointestinal microbiota. Sulforaphane gained scientific popularity due to its antioxidant and anti-cancer properties. However, its toxicity profile and potential to cause adverse effects remain largely unidentified. Thus, this study aimed to generate SFN-triggered adverse outcome pathway (AOP) by looking at the relationship between SFN-chemical structure and its toxicity, as well as SFN-gene interactions. Quantitative structure-activity relationship (QSAR) analysis identified 2 toxophores (Derek Nexus software) that have the potential to cause chromosomal damage and skin sensitization in mammals or mutagenicity in bacteria. Data extracted from Comparative Toxicogenomics Database (CTD) linked SFN with previously proposed outcomes via gene interactions. The total of 11 and 146 genes connected SFN with chromosomal damage and skin diseases, respectively. However, network analysis (NetworkAnalyst tool) revealed that these genes function in wider networks containing 490 and 1986 nodes, respectively. The over-representation analysis (ExpressAnalyst tool) pointed out crucial biological pathways regulated by SFN-interfering genes. These pathways are uploaded to AOP-helpFinder tool which found the 2321 connections between 19 enriched pathways and SFN which were further considered as key events. Two major, interconnected AOPs were generated: first starting from disruption of biological pathways involved in cell cycle and cell proliferation leading to increased apoptosis, and the second one connecting activated immune system signaling pathways to inflammation and apoptosis. In both cases, chromosomal damage and/or skin diseases such as dermatitis or psoriasis appear as adverse outcomes.

AB  - Toxic metals (cadmium (Cd), lead (Pb), mercury (Hg) and arsenic (As)) and plastificators (bis (2 – ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP)) and bisphenol A (BPA)) have been suggested to aid in colorectal carcinoma (CRC) advancement. Sulforaphane (SFN), isothiocyanate from cruciferous vegetables, diminishes chemical carcinogenesis susceptibility, but has been shown to act as a friend or a foe depending on various factors. By conducting the mechanistic toxicogenomic data mining approach, this research aimed to determine if SFN can alleviate toxic-metal and/or phthalate/BPA mixture-induced CRC at the gene level. Comparative Toxicogenomics Database, ToppGene Suite portal, Cytoscape software, InteractiVenn and Gene Expression Omnibus (GEO) database (GEO2R tool) was used. Among the mutual genes for all the investigated substances, SFN had a protective impact only through PTGS2. Other proposed protective SFN-targets included ABCA1, ALDH2, BMP2, DPYD, MYC, SLCO2A1, and SOD2, only in the case of phthalates/BPA exposure. The only additional gene relevant for SFN protection against the toxic metal mixture-induced CRC was ABCB1. Additionally, the majority of the top 15 molecular pathways extracted for SFN impact on phthalate and BPA mixture-linked CRC development were directly linked with cancer development, which was not the case with the toxic metal mixture. The current research has indicated that SFN is a more effective chemoprotective agent against CRC induced by phthalates/BPA mixture than by toxic-metal mixture. It has also presented the value of computational methods as a simple tool for directing further research, selecting appropriate biomarkers and exploring the mechanisms of toxicity.

AB  - The current study aimed to assess the connection between the mixture of lead (Pb), cadmium (Cd), arsenic (As), methylmercury (MeHg) and decabrominated diphenyl ether (decaBDE) and thyroid function, by using in silico toxicogenomic data-mining approach. To obtain the linkage between investigated toxic mixture and thyroid diseases (TDs), the Comparative Toxicogenomics Database (CTD) was used, while gene ontology (GO) enrichment analysis was performed by ToppGeneSuite portal. The analysis has shown 10 genes connected to all chemicals present in the mixture and TDs (CAT, GSR, IFNG, IL1B, IL4, IL6, MAPK1, SOD2, TGFB1, TNF), most of which were in co-expression (45.68%), or belonged to the same pathway (30.47%). Top 5 biological processes and molecular functions affected by the investigated mixture emphasized the role of two common mechanisms – oxidative stress and inflammation. Cytokines and inflammatory response was listed as the main molecular pathway that may be triggered by simultaneous exposure to toxic metal(oid)s and decaBDE and connected to TDs. The direct relations between Pb/decaBDE and redox status impairment in thyroid tissue was confirmed by our chemical-phenotype interaction analysis, while the strongest linkage between Pb, As and decaBDE and thyroid disorders was found. The obtained results provide better understanding of molecular mechanisms involved in the thyrotoxicity of the investigated mixture, and can be used to direct further research.

AB  - Exposure to low levels of a toxic metal lead (Pb) affects human health, and its effect as an endocrine disruptor has been reported. However, the precise role of Pb in endocrine health is still unclear because no dose-response relationship has been established for such an effect. The present study aimed to examine blood Pb levels (BLLs) in relation to serum levels of free triiodothyronine (fT3), free thyroxine (fT4), thyroid stimulating hormone (TSH), and insulin in 435 nonoccupationally exposed Serbian subjects (218 women, 217 men, 18–94 years of age, mean age 48). In addition, benchmark dose (BMD) values were calculated for these endocrine endpoints using the PROAST 70.1 software. An explicit dose-response dependency between BLL and TSH, fT3, fT4, testosterone, and insulin serum levels was evident from BMD modelling. The results support the positive association between BLLs and serum insulin levels, with observed dose-response and calculated BMD values of 1.49 and 0.74 μg Pb/dL in males and females, respectively. Collectively, our findings reported potential endocrine-disrupting effects of Pb at the environmental exposure levels experienced by current Serbian population. They also strengthen the notion that the blood Pb threshold level for an endocrine effect is low.

In vivo subacute study was performed on rats - five groups (n = 6): (1) Control: corn oil, (2) DEHP: 50 mg/kg b.w./day, (3) DBP: 50 mg/kg b.w./day, (4) BPA: 25 mg/kg b.w./day, (5) MIX: DEHP + DBP + BPA. Zebrafish embryos were exposed to the investigated substances in different doses, singularly and combined (binary and ternary mixtures). Liver injury was linked to 75 DEHP, DBP, and BPA genes, mostly connected to inflammation/oxidative stress. In rats, significant alterations in redox status/bioelements and pathohistology were most notable or exclusively present in MIX (probable additive effects). BPA decreased liver area (LA) index in dose-dependent manner. DEHP (< 2 µg/mL) and DBP (≤ 5 µg/mL) reduced LA values, while their higher doses increased LA index. The effect of DBP in binary mixtures led to a lethal outcome at the two highest concentrations, while the hepatotoxicity of DEHP/DBP/BPA mixture was dictated by BPA (confirmed by the benchmark dose analysis).

AB  - The present study investigated the effects of PCBs on the rat kidneys with attention given to the determination critical effect dose (CED) using the Benchmark dose (BMD) approach. Male albino Wistar rats (7 animals per group) were given by oral gavage Aroclor 1254 dissolved in corn oil at doses of 0.0, 0.5, 1, 2, 4, 8, or 16 mg/kg b.w./day for 28 days. The PCB nephrotoxicity was manifested by a dose-dependent changes in serum urea levels. The study has also revealed PCB-induced oxidative stress induction in kidneys. The observed nephrotoxic effects can be partly explained by oxidative damage of lipids and proteins in the kidneys due to observed reduced CuZnSOD activity and disturbances in antioxidant protection. Аll the renal oxidative stress parameters showed dependence on PCB oral doses as well as internal, measure kidney PCB levels. Calculated BMDL values were lower than estimated no observed adverse effect levels (NOAEL) based on the study, suggesting the importance of BMD approach use in future risk assessment.

AB  - Exposure to lead (Pb) and cadmium (Cd) poses risk to human health. It is known that
these metals have toxic impact on male reproductive system, leading to physiological
disorders and infertility. Limited data indicates the carcinogenic potential of Pb, while Cd has
been recognized as carcinogen. Benchmark dose-effect modeling can be applied to data from
human, animal and ecotoxicological studies with the aim to obtain Benchmark dose (BMD),
starting point in human health risk assessment. The aim of this study was to use Benchmark
modeling to determine the dose-effect relationship between Pb and Cd levels in tissues of
testicular and prostate cancer patients and serum testosterone levels. The study was
conducted at the Clinical Center of Serbia, and included 104 patients with prostate and
testicular cancer. Cd and Pb levels (ng/g) were measured by atomic absorption
spectrophotometry in isolated healthy surrounding and carcinoma-affected tissues.
Testosterone levels (ng/mL) were measured using the chemiluminescence immunoassay
(CLIA) method. Dose-effect modeling was performed using PROAST70.1 software with
continuous data. The dose dependence was obtained between Cd levels in tumor tissue and
testosterone levels (BMD: 0.0024 ng Cd/g, prostate cancer and 0.0038 ng Cd/g, testicular
cancer). Dose dependence was obtained between Cd levels in healthy surrounding tissue and
testosterone levels (BMD: 0.0092 ng Cd/g). No dose dependence was obtained when
modeling Pb levels as a dose. The data from this study indicate a potential link between Cd
and testosterone levels, i.e. potential association of Cd exposure with male reproductive
health.

AB  - The endocrine potential of Cd and Pb, an important mechanism of their toxicity, has
been established in certain hormone-dependent cancers (1,2). This study aimed to
determine Cd and Pb levels in blood, tumor and healthy surrounding tissue of patients with
breast, prostate and testis cancer and investigate the correlation of Cd and Pb with sex
hormone levels in the patient's blood. The study involved 55 breast, 41 prostate and 52 testis
cancer patients, while healthy women (41) and men (61) represented control groups.
Electrothermal atomic absorption spectrophotometry was used for Cd and Pb levels
determination. Significantly higher Cd levels, i.e. lower Pb in tumor tissue compared to the
healthy surrounding tissue were found in patients with breast cancer. A positive correlation
was confirmed between Cd levels in the changed tissue and both human gonadotropins, and
a negative correlation with estradiol, as well between Pb in tumor tissue and testosterone
levels. Patients with prostate and testis cancer were characterized by significantly higher
blood Cd levels compared to healthy subjects. Furthermore, significant Cd and Pb tumor
tissue accumulation was shown in prostate and testis cancer patients. A significant positive
correlation was found between blood Cd and estradiol levels in patients with prostate
cancer. The study highlighted higher Cd level as a significant predictor of cancer, and
confirmed impaired sex hormone homeostasis as pivotal mechanism of toxicity underlying
the toxic effects of Cd and Pb in patients with breast, prostate and testis cancer.
AB  - Endokrini potencijal kadmijuma (Cd) i olova (Pb), kao važan mehanizam toksičnosti
oba metala, potvrđen je kod određenih hormon-zavisnih karcinoma (1,2). Ova studija je
imala za cilj da utvrdi koncentracije Cd i Pb u krvi, tumorskom i okolnom zdravom tkivu
pacijenata sa karcinomom dojke, prostate i testisa i ispita korelaciju Cd i Pb sa nivoom polnih
hormona u krvi pacijenata. Obuhvatila je 55 pacijentkinja sa karcinomom dojke, 41 pacijenta
sa karcinomom prostate i 52 pacijenta sa karcinomom testisa, dok su u kontrolnu grupu bile
uključene zdrave žene (41) i zdravi muškarci (61). Koncentracije Cd i Pb su analizirane
elektrotermalnom atomskom apsorpcionom spektrofotometrijom. Značajno više
koncentracije Cd, odnosno niže Pb u tumorskom u odnosu na okolno zdravo tkivo utvrđene
su kod pacijentkinja sa karcinomom dojke. Pozitivna korelacija je potvrđena između
koncentracija Cd u tkivu izmenjene strukture i oba humana gonadotropina, a negativna sa
estradiolom, te između Pb u tumorskom tkivu i testosterona. Pacijente sa karcinomom

abstract = "The endocrine potential of Cd and Pb, an important mechanism of their toxicity, has
been established in certain hormone-dependent cancers (1,2). This study aimed to
determine Cd and Pb levels in blood, tumor and healthy surrounding tissue of patients with
breast, prostate and testis cancer and investigate the correlation of Cd and Pb with sex
hormone levels in the patient's blood. The study involved 55 breast, 41 prostate and 52 testis
cancer patients, while healthy women (41) and men (61) represented control groups.
Electrothermal atomic absorption spectrophotometry was used for Cd and Pb levels
determination. Significantly higher Cd levels, i.e. lower Pb in tumor tissue compared to the
healthy surrounding tissue were found in patients with breast cancer. A positive correlation
was confirmed between Cd levels in the changed tissue and both human gonadotropins, and
a negative correlation with estradiol, as well between Pb in tumor tissue and testosterone
levels. Patients with prostate and testis cancer were characterized by significantly higher
blood Cd levels compared to healthy subjects. Furthermore, significant Cd and Pb tumor
tissue accumulation was shown in prostate and testis cancer patients. A significant positive
correlation was found between blood Cd and estradiol levels in patients with prostate
cancer. The study highlighted higher Cd level as a significant predictor of cancer, and
confirmed impaired sex hormone homeostasis as pivotal mechanism of toxicity underlying
the toxic effects of Cd and Pb in patients with breast, prostate and testis cancer., Endokrini potencijal kadmijuma (Cd) i olova (Pb), kao važan mehanizam toksičnosti

uključene zdrave žene (41) i zdravi muškarci (61). Koncentracije Cd i Pb su analizirane
elektrotermalnom atomskom apsorpcionom spektrofotometrijom. Značajno više
koncentracije Cd, odnosno niže Pb u tumorskom u odnosu na okolno zdravo tkivo utvrđene
su kod pacijentkinja sa karcinomom dojke. Pozitivna korelacija je potvrđena između

AB  - Lead (Pb) is one of the most important toxic metals without known physiological role.
Recent data indicate that any exposure, even low, can be harmful. Therefore, safe blood lead
levels, as well as tolerating daily intake, have not been identified. In adults, the most sensitive
effect is increase in systolic blood pressure, while in children, the most sensitive effect is on
cognition. Therefore, the aim of this study was to examine the effects of low lead doses on the
central nervous and cardiovascular system in a rat model. The study was conducted on
Wistar rats (n = 42; 7 groups) treated for 28 days, with increasing doses of 0.1; 0.5; 1; 3; 7;
15 mgPb/kg b.w./day to simulate real exposure. After the sacrifice, the brain and heart were
isolated, in which the parameters of oxidative status, bioelements and lead levels were
determined. Benchmark modelling of the dose-effect relationship was performed using
PROAST 70.1 software (RIVM, Netherlands). The obtained results indicate that lead leads to
the induction of oxidative stress and dishomeostasis of bioelements. The lowest value of the
Benchmark dose (BMD) was obtained for increase the total oxidative status in the brain
(4.49e-06 mgPb/kg/b.w./day), which is the most sensitive effect. In the case of heart, the
most sensitive effect was increase in malondialdehyde (BMD: 0.000248 mgPb/kg/b.w./day).
Obtained results indicate that low lead doses have toxic effects on heart and brain. Obtained
BMD may be useful in assessing human health risk of low lead dose exposure.
AB  - Olovo (Pb) je jedan od najznačajnijih toksičnih metala bez poznate fiziološke uloge u
organizmu. Novija istraživanja ukazuju da potencijalno svaka izloženost olovu, čak i niskim
dozama, može biti štetna, te tolerišući dnevni unos, kao ni bezbedan nivo u krvi, nisu
utvrđeni. Kod odraslih, kao najosetljiviji efekat izdvaja se povećanje sistolnog krvnog
pritiska, dok je kod dece to poremećaj kognicije. Imajući navedeno u vidu, cilj ove studije bio
je da se na animalnom modelu ispita uticaj niskih doza olova na centralni nervni i
kardiovaskularni sistem, koji su do sada identifikovani kao najosetljiviji na dejstvo olova, i
odrede Benchmark doze (BMD). Studija je sprovedena na modelu Wistar pacova koji su
podeljeni u 7 grupa tretiranih tokom 28 dana rastućim dozama olova 0, 0,1; 0,5; 1; 3; 7; 15
mg Pb/kg t.m./dan kako bi se simulirala realna izloženost. Nakon žrtvovanja pacova,
izolovani su mozak i srce u kojima su određeni olovo, bioelementi i parametri oksidativnog
statusa. Benchmark modelovanje odnosa doza-efekat vršeno je pomoću PROAST 70.1
softvera (RIVM, Holandija). Dobijeni rezultati ukazuju da olovo dovodi do indukcije
oksidativnog stresa i poremećaja homeostaze bioelemenata. Najniža BMD dobijena je za
povećanje totalnog oksidativnog statusa u mozgu (4,49e-06 mg Pb/kg t.m./dan), što
predstavlja najosetljiviji efekat, a u srcu je to povećanje koncentracije malondialdehida
(BMD: 0,000248 mg Pb/kg t.m./dan). Dobijeni rezultati ukazuju da i niske doze olova mogu
ispoljiti toksične efekte na srce i mozak, a dobijene BMD su od značaja za procenu rizika
olova po zdravlje ljudi.

AB  - The main objective of this research was to conduct a dose–response modeling between the internal dose of measured blood Cd, As, Hg, Ni, and Cr and hormonal response of serum testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). The study included 207 male participants from subjects of 5 different cohorts (patients with prostate, testicular, and pancreatic cancer, patients suffering from various thyroid and metabolic disorders, as well as healthy volunteers), enrolled from January 2019 to May 2021 at the Clinical Centre of Serbia in Belgrade, Serbia. Benchmark dose–response modeling analysis was performed with the PROAST software version 70.1, showing the hormone levels as quantal data. The averaging technique was applied to compute the Benchmark dose (BMD) interval (BMDI), with benchmark response set at 10%. Dose-response relationships between metal/metalloid blood concentration and serum hormone levels were confirmed for all the investigated metals/metalloid and hormones. The narrowest BMDI was found for Cd-testosterone and Hg-LH pairs, indicative of high confidence in these estimates. Although further research is needed, the observed findings demonstrate that the BMD approach may prove to be significant in the dose–response modeling of human data.

AB  - Numerous risk factors have been associated with breast cancer (BC), exposure to metalloestrogen, like lead, being such. Since lead involvement in BC is still equivocal, we focused on lead levels in three compartments of BC patients, blood, healthy, and malignant tissues. Also, as the cholesterol role in cancer development was recognized at the beginning of the twentieth century and led to involvement in lipid profile impairment, we further extend our research on lipid profile and enzymes responsible for maintaining lipid balance in BC patients. Fifty-five women diagnosed with BC were enrolled in the study. Forty-one healthy women represented the control group. Lead levels in blood, healthy surrounding and malignant tissue, and lipid profile parameters in serum, were determined. Higher lead levels were obtained in surrounding healthy tissue samples compared to cancerous tissue samples, while blood lead levels of BC women did not differ significantly from the control group. The altered lipid profile scheme in women diagnosed with breast cancer contained significantly higher triglycerides levels (P < 0.001). Moreover, logistic regression analysis revealed triglycerides as a significant predictor of BC (OR = 2.6; P < 0.01). Although statistical significance was missing for lower paraoxonase-1 (PON-1) activities observed in BC women, multivariate logistic regression singled out PON-1 activities as significant BC predictors. The result of the present study further indicated oxidative status imbalance and tissue levels bioelements perturbation. Obtained results in the present study propose possible lead involvement in BC onset accompanied with bioelements redistribution and oxidative stress occurrence.

abstract = "Numerous risk factors have been associated with breast cancer (BC), exposure to metalloestrogen, like lead, being such. Since lead involvement in BC is still equivocal, we focused on lead levels in three compartments of BC patients, blood, healthy, and malignant tissues. Also, as the cholesterol role in cancer development was recognized at the beginning of the twentieth century and led to involvement in lipid profile impairment, we further extend our research on lipid profile and enzymes responsible for maintaining lipid balance in BC patients. Fifty-five women diagnosed with BC were enrolled in the study. Forty-one healthy women represented the control group. Lead levels in blood, healthy surrounding and malignant tissue, and lipid profile parameters in serum, were determined. Higher lead levels were obtained in surrounding healthy tissue samples compared to cancerous tissue samples, while blood lead levels of BC women did not differ significantly from the control group. The altered lipid profile scheme in women diagnosed with breast cancer contained significantly higher triglycerides levels (P < 0.001). Moreover, logistic regression analysis revealed triglycerides as a significant predictor of BC (OR = 2.6; P < 0.01). Although statistical significance was missing for lower paraoxonase-1 (PON-1) activities observed in BC women, multivariate logistic regression singled out PON-1 activities as significant BC predictors. The result of the present study further indicated oxidative status imbalance and tissue levels bioelements perturbation. Obtained results in the present study propose possible lead involvement in BC onset accompanied with bioelements redistribution and oxidative stress occurrence.",

AB  - Lead (Pb) is a toxic metal that affects almost all human’s system and organs, with the nervous system as the most sensitive. Better understanding of the Pb neurobehavioral effects and neurotoxicity requires realistic study scenarios based on low level exposure. The aim of this study was to determine neurotoxic effects and mechanisms of Pb in six low doses and to establish dose-response relationship for these effects and related Benchmark dose (BMD). Forty-two, male albino Wistar rats were randomized into seven groups, control and Pb-exposed: 0.1, 0.5, 1, 3, 7 and 15 mg Pb/kg body weight/day (oral gavage) for 28 days. Behavioural tests (Elevated plus maze test, Spontaneous locomotor activity test and Novel object recognition test) were conducted in the last week of experiment, in the control, lower (0.5 mg Pb/kg), middle (3 mg Pb/kg) and higher (15 mg Pb/kg) dose groups. The acetylcholinesterase activity, oxidative status and essential elements levels (Cu, Zn, Mn and Fe) were measured in brain tissue along with histological analyses. External and internal dose-response analyses were performed using PROASTweb 70.1 software. The results have shown that subacute exposure to very low doses of Pb resulted in memory deficits in rats that was accompanied with acetylcholinesterase enzyme activity decrease. The observed hyperactive behaviour was accompanied by dose-dependent induction of brain oxidative stress and Zn elevation. The histological alterations in Purkinje cells were only detected in the group treated with the highest Pb dose. The lowest BMD considering entire oxidative status was calculated based on total oxidative status (4.5e-06 mg Pb/kg b.w./day). The findings reported in our study may be beneficial in further evaluating the health consequences and human health risk assessment of low-level Pb exposure.

AB  - Exposure to toxic metals, including lead (Pb), were found as important risk factor for cardiovascular diseases. The aim of the study was to simulate low-level subacute Pb exposure scenario and to determine redox status, redox scores (OXY-score, damage score and protective score) and copper (Cu), zinc (Zn), iron (Fe) and manganese (Mn) levels in cardiac tissue of Wistar rats. Based on the obtained results we have established dose-toxic response relationship and derived Benchmark dose. The male Wistar rats were divided in seven groups (n = 6), six threated groups that received 0.1; 0.5; 1; 3; 7; 15 mg Pb/kg body weight/day for 28 days, by oral gavage and control group. The results of the presented study demonstrated that Pb affect cardiac tissue by inducing production of superoxide anion radical (O2.-) and consequently raising malondialdehyde (MDA) levels. The positive trend in OXY-score and damage score were determined. Effect size analysis showed that the main toxic effects were oxidative damage and elevation of MDA. The lowest BMD was calculated for MDA (2.2e-0.6 mg Pb/kg b.w./day). Obtained BMD may be useful in further assessing point of departure in the human health risks assessment of low-level Pb exposure scenario.

AB  - Crayons and colored pencils for children may contain toxic elements (TEs) exhibiting potential risk for children’s health including cognitive deve- lopment, after their ingestion, through mouthing and chewing and eventually, their accumulation. The aim of this study was to determine total content of As, Pb, Cr, Cd, Ni and Sb and estimate their bioaccessibility conducting artificial saliva extraction. Sixty samples of colored pencils and crayons from 10 manu- facturers were analyzed. Microwave acid assisted digestion followed by induct- ively coupled plasma optical spectroscopy (ICP-OES) was performed for deter- mination of total content of TEs. Simulation of extraction by artificial saliva was applied to get more reliable data when bioavailability is concerned. The total concentrations of TEs were higher in colored pencils than in crayons and their maximum levels were: 5.78, 9.36, 9.97, 0.615, and 6.63 mg kg -1 for As, Pb, Cr, Cd and Ni, respectively. Concentration of Sb was below the detection limit for all investigated samples. This study showed that concentration of As and Pb in several samples did not comply with European Union regulative. Bioaccessibility study showed the high degree of leaching of Cr and As from pencils, but regardless of extracted portions, concentrations of selected inves- tigated TEs were below allowed levels.

Испитивано је укупно 60 узорака бојица, различитих боја, 10 различитих произвођача.

AB  - Mercury (Hg) is one of the most important environmental pollutants with endocrine-
disrupting properties. There is little data from epidemiological studies describing the dose-
response relationship between toxic metal levels and hormone levels. The aim of this study was
to use the nearest neighbor matching analysis to determine the difference in Hg concentration in
healthy/sick subjects with thyroid disease and to use Benchmark modeling to determine the dose-
response relationship between Hg levels in the blood and thyroid-stimulating hormone (TSH) and
thyroid hormones in serum. Blood samples were collected and used for Hg measurement using
the ICP-MS method, and separated serum was used for hormone analysis. The study showed the
existence of a statistically significant difference in Hg levels measured in healthy and sick subjects
and the existence of a dose-response relationship between Hg and all measured hormones, with a
narrow interval obtained for the Hg-TSH pair. The results of this research support the use of the
Benchmark dose approach for the purpose of analyzing data from human studies, and our further
research will be focused on examining the impact of low doses on animal models in order to
determine more precise effects of low doses on the organism.
AB  - Živa (Hg) je jedan od najznačajnijih zagađivača životne sredine sa osobinama endokrinog ometača. Malo je podataka iz epidemioloških studija koji opisuju odnos doza-odgovor između nivoa toksičnih metala i nivoa hormona. Cilj ovog rada bio je da primenom nearest neighbor matching analize utvrdi razliku u koncentraciji Hg kod zdravih/obolelih ispitanika od bolesti štitaste žlezde i da primenom Benchmark modelovanja utvrdi odnos doza-odgovor između nivoa Hg u krvi i tireostimulišućeg hormona (TSH) i tiroidnih hormona u serumu. Uzorci krvi su sakupljeni i korišćeni za merenje Hg uz pomoć ICP-MS metode, a izdvojeni serum korišćen je za analizu hormona. Studija je pokazala postojanje statistički značajne razlike u nivoima Hg koji su izmereni kod zdravih i bolesnih ispitanika i postojanje odnosa doza-odgovor između Hg i svih merenih hormona, pri čemu je uzak interval dobijen za Hg-TSH par. Rezultati ovog istraživanja podržavaju upotrebu Benchmark dose pristupa u svrhu analize podataka iz humanih studija, a naša dalja istraživanja će biti usmerena na ispitivanje uticaja niskih doza na životinjskim modelima, u cilju utvrđivanja preciznijih efekata niskih doza na organizam.

Cilj ovog rada bio je da primenom nearest neighbor matching analize utvrdi razliku u koncentraciji Hg kod zdravih/obolelih ispitanika od bolesti štitaste žlezde i da primenom Benchmark modelovanja utvrdi odnos doza-odgovor između nivoa Hg u krvi i tireostimulišućeg hormona (TSH) i tiroidnih hormona u serumu. Uzorci krvi su sakupljeni i korišćeni za merenje Hg uz pomoć ICP-MS metode, a izdvojeni serum korišćen je za analizu hormona. Studija je pokazala postojanje statistički značajne razlike u nivoima Hg koji su izmereni kod zdravih i bolesnih ispitanika i postojanje odnosa doza-odgovor između Hg i svih merenih hormona, pri čemu je uzak interval dobijen za Hg-TSH par. Rezultati ovog istraživanja podržavaju upotrebu Benchmark dose pristupa u svrhu analize podataka iz humanih studija, a naša dalja istraživanja će biti usmerena na ispitivanje uticaja niskih doza na životinjskim modelima, u cilju utvrđivanja preciznijih efekata niskih doza na organizam.",

AB  - Background/Aim. Health professions education is facing
emerging issues. A comprehensive situation analysis was
performed among academic staff, healthcare practitioners,
and healthcare science students to address and respond to
new trends. The aim of the study was to investigate the
attitude, perception, and the recognized needs towards
experiential education (EE), interprofessional education
(IPE), and teaching competencies development (TCD). The
critical evaluation of the existing quality standards for
further quality improvement in health professions education
in Serbia was provided. Methods. The survey on EE, IPE,
and TCD was conducted within the Reinforcement of the
Framework for Experiential Education in Serbia
(ReFEEHS) project, co-funded by the Erasmus+ program
of the European Comission at four Serbian universities (the
University of Belgrade, the University of Kragujevac, the
University of Niš, and the University of Novi Sad). Four
task groups were appointed to perform a desk review of the
existing curricula, recommendations, and practices within
each of the four health professions education (Medicine,
Pharmacy, Dentistry, and Nursing) in Serbia and assess the
level of compliance with relevant educational policies and
practices in the European Union . Results. A total of 1,507
respondents completed the survey. A highly expressed
positive attitude was found towards EE, IPE, and TCD
among all the respondents. The majority of the respondents 
(> 70%) shared that EE should be organized in real-life
practice and involve students’ work under the supervision
of a qualified supervisor, as well as interactions with patients
and healthcare professionals. About 90% of the
respondents supported the inclusion of IPE teaching
activities into EE, with 77% of students expressing high
motivation to attend those classes, whereas 93% of
academic staff was eager to deliver and teach joint IPE
subjects. Only 20% of academic staff has already attended
some TCD program, while 75% recognized the need for its
organization. Moreover, 90% of healthcare practitioners
have recognized that mentors/clinical supervisors also need
additional skills for effective mentoring work within health
science education. Based on the survey results,
recommendations for improvement were given within three
educational fields, healthcare science curricula, professional
practice (traineeship), teaching staff, and regulations.
Conclusion. The results derived from the survey served as
a starting but also a vital point for higher education
improvement in Serbia. All interested parties – academia,
students, healthcare professionals, and regulatory bodies
should collaborate on achieving improved, contemporary,
and transformative health professions education.
AB  - Uvod/Cilj. Obrazovanje u oblasti zdravstva suočava se sa novim pitanjima. Da bi se odgovorilo na savremene zahteve obrazovanja zdravstvenih radnika, sprovedena je sveobuhvatna situaciona analiza. Cilj istraživanja bio je da se istraže stavovi, percepcije i prepoznaju potrebe akademske zajednice, zdravstvenih radnika i studenata zdravstvenih profesija, u odnosu prema učenju u realnom radnom okruženju, tj. nastavi u praksi (experiential education - EE), interprofesionalnom obrazovanju (interprofessional education - IPE) i unapređenju nastavničkih kompetencija (teaching competencies development - TCD). Radi daljeg unapređenja u oblasti obrazovanja, za zdravstvene radnike u Srbiji obezbeđeno je kritičko vrednovanje postojećih standarda kvaliteta. Metode. Istraživanje je sprovedeno u okviru projekta Reinforcement of the Framework for Experiential Education in Serbia (ReFEEHS), ko-finansiranog od strane Erasmus+ programa Evropske komisije na četiri univerziteta u Republici Srbiji (Univerzitet u Beogradu, Univerzitet u Kragujevcu, Univerzitet u Nišu i Univerzitet u Novom Sadu). Određene su četiri radne grupe, sa zadatkom razmatranja trenutnih kurikuluma, preporuka i prakse u okviru svake zdravstvene profesije (medicina, farmacija, stomatologija, sestrinstvo), kao i procene njihove usklađenosti sa relevantnim preporukama i praksom u obrazovanju u Evropskoj uniji. Rezultati. U istraživanju je učestvovalo 1 507 ispitanika. Pozitivan stav prema EE, IPE i TCD zabeležen je među svim ispitanicima. Više od 70% ispitanika iskazalo je stav o tome da je potrebno organizovati EE, tj. nastavu u praksi u realnom radnom okruženju, što bi podrazumevalo stručni rad studenata pod nadzorom kompetentnog mentora, ali i interakciju sa bolesnicima, kao i interakciju sa zdravstvenim radnicima. Oko 90% ispitanika podržalo je uključivanje IPE nastavnih aktivnosti u kurikulume; 77% studenata izrazilo je motivisanost da prisustvuju zajedničkim predmetima, dok je čak 93% nastavnika i saradnika iskazalo volju da učestvuju u kreiranju i podučavanju nastavnih jedinica u okviru IPE. Prethodno je samo 20% nastavnika/saradnika pohađalo neki TCD program, dok je čak 75% prepoznalo potrebu za organizacijom tih programa; 90% zdravstvenih radnika smatralo je da su za efikasan mentorski rad u obrazovanju u oblasti zdravstvene nauke potrebne dodatne veštine mentora/kliničkih supervizora. Na osnovu sagledanih rezultata upitnika, date su preporuke za unapređenje visokog obrazovanja u okviru tri obrazovne oblasti budućih zdravstvenih radnika, koje se odnose na kurikulum, studentsku stručnu praksu/klinički staž, nastavno osoblje i regulatorne aspekte. Zaključak. Dobijeni rezultati korišćeni su kao polazna, ali veoma značajna tačka za unapređenje visokog obrazovanja u Srbiji. Sve zainteresovane strane - akademska zajednica, studenti, zdravstveni radnici i regulatorna tela, treba da sarađuju u cilju postizanja unapređenog i savremenog obrazovanja zdravstvenih radnika.

AB  - One of the most polluted cities in Serbia and Europe is Bor, due to mining and
smelting processes in Mining-Metallurgical Complex in Bor. Mining activities release mainly
SO2 and paritculate matter in air (1) and, as arsenic is usually found in copper and lead ores,
air quality monitoring in Bor has been showing its presence in exceeded annual limit
concentrations in past few years. Exposure to arsenic is related with anemia, skin changes,
peripheral neuropathy and cancer development. This study was carried out to assess
children’s and adult’s exposure to arsenic bound to PM10 and to charcterize risk from their
exposure through the air in the city of Bor. Mean yearly concentrations of arsenic were used
from Reports of the Serbian Enviromental Protection Agency, for measuring stations: Bor-
City park, Bor 1, Bor 2 and Bor-Jugopetrol. The USEPA method was used to assess non-
carcinogenic and carcinogenic risk, which classifies non-carcinogenic risk as acceptable (<1)
or unacceptable (>1) based on hazard quotient (HQ) values for three main exposure
pathways, while cancer risk classification is based on CR values also as acceptable (<1×10 -4 )
or unacceptable (>1×10 -4 ) (2). HQinh values exceeded safe level both for children and adults
on all measuring stations, describing risk as unacceptable via inhalation exposure.
Unacceptable carcinogenic risk for children was calculated on measuring station Bor-
Jugopetrol and for adults on measuring stations Bor-City park, Bor 1 and Bor-Jugopetrol.
Actions for reduction of arsenic release into the air should be taken due to obtained results
for city of Bor.
AB  - Grad Bor spada među najzagađenije gradove u Republici Srbiji i Evropi. Najveći izvor
zagađenja u ovom gradu predstavlja rudnik bakra, Rudarsko-topioničarski basen Bor, usled
emisije, predominantno, SO2 i suspendovanih čestica (1). Arsen je čest pratilac ruda bakra i
olova, te se iz godine u godinu monitoringom kvaliteta vazduha uočava njegovo prisustvo u
koncentracijama koje prelaze dozvoljene godišnje granice. Izloženost arsenu može dovesti
do razvoja anemije, promena na koži, periferne neuropatije, ali i razvoja karcinoma. Cilj rada
bio je da se proceni izloženost i okarakteriše rizik dece i odraslih od izloženosti arsenu iz
PM10 čestica tj. putem zagađenog vazduha u gradu Boru. Vrednosti prosečnih godišnjih
koncentracija arsena u vazduhu su preuzete iz godišnjih izveštaja Agencije za zaštitu životne
sredine, za merne stanice: Bor-Gradski park, Bor 1, Bor 2 i Bor-Jugopetrol. Zdravstveni rizik
je procenjen metodologijom koju preporučuje Američka agencija za zaštitu životne sredine.
Na osnovu vrednosti količnika hazarda (HQ) za oralni, inhalacioni i dermalni put unosa, ne-
karcinogeni rizik se klasifikuje kao prihvatljiv (<1) ili neprihvatljiv (>1), dok se karcinogeni
rizik klasifikuje na osnovu vrednosti CR, takođe kao prihvatljiv (<1×10-4 ) ili neprihvaljiv
(>1×10 -4 ) (2). Izračunate vrednosti HQinh za decu i odrasle prelaze vrednost 1 ukazujući na
neprihvatljiv rizik od izloženosti arsenu preko PM10 čestica iz zagađenog vazduha na svim
razmatranim mernim stanicama. Neprihvatljiv karcinogeni rizik za decu je izračunat na
stanici Bor-Jugopetrol, a za odrasle na stanicama Bor-Gradski park, Bor 1 i Bor-Jugopetrol.
Dobijeni rezultati ukazuju na preku potrebu preduzimanja mera u cilju smanjenja emisije
arsena u vazduh u Boru.
