AB  - Poslednjih decenija prošlog veka naučnici su utvrdili da pojedine hemikalije, mogu uticati na brojne sisteme organa i izazvati štetne efekte po naše zdravlje. Među hemikalijama sa kojima dolazimo u kontakt gotovo svakodnevno, posebno mesto zauzimaju hemikalije koje mogu delovati na endokrini sistem. ...
AB  - In the last decades of the twentieth century, scientists have observed that exposure to certain, human-made chemicals can affect numerous organ systems and cause harmful effects on our health. Among the chemicals hiding in everyday products, substances of special concern are those that can affect the endocrine system. ...

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  - The microelements chromium, cobalt and nickel are necessary for the proper
functioning of the organism. At higher concentrations, they can cause toxic effects (organ
disfunction, genetic damage). They are widespread in the enviroment. They reach our body
through food, water, air and/or skin. The aim of this study was to determine the reference
values of chromium, cobalt and nickel in the blood of adult residents of Belgrade and
determine the degree of influence of individual, socioeconomic factors and lifestyle habits on
blood levels of these metals. The study population consisted of adults, healthy population, 18
to 65 years of age, who were voluntary blood donors. The study included 715 men (72.7%)
and 269 women (27.3%). Blood collected in vacutainers with heparin, was used for analysis.
984 samples were analysed. The metals were determined using inductively coupled plasma
mass spectrometry (7700x, Agilent, USA), with octopol reactive system and micro-flow
nebulizer. The average age of participants was 37.2 10.8. The reference values of the
analysed metals, shown as the 95 percentile, were 0.95µg/L, 0.62µg/L and 1.46µg/L for
chromium, cobalt and nickel, respectively, and were in good correlation with the values
obtained in biomonitoring studies conducted in Europe. This study showed that population
of Serbian origin had significantly lower blood concentrations of chromium, that cobalt blood
levels in women were significantly higher and cobalt and nickel levels increased with age in
both sexes. Education and economic status, cigarette smoking and sports did not significantly
affect the levels of these metals in the blood.
AB  - Mikroelementi hrom, kobalt i nikl su potrebni za pravilno funkcionisanje organizma. U
većim koncentracijama mogu ispoljiti toksične efekte poput ometanja pravilne funkcije
organa i dovesti do genetskih oštećenja i karcinogeneze. Široko su rasprostranjeni u životnoj
sredini. Putem hrane, vode, vazduha i/ili kože dospevaju u naš organizam. Cilj rada bio je da
se utvrde referentne vrednosti hroma, kobalta i nikla u krvi odraslih stanovnika grada
Beograda, kao i stepen uticaja individualnih, socioekonomskih faktora i životnih navika na
nivoe ovih metala u krvi. Ispitivanu populaciju je činilo odraslo, zdravo stanovništvo,ukupno
715 muškaraca (72,7%) i 269 žena (27,3%) od 18 do 65 godina starosti, koji su bili
dobrovoljni davaoci krvi. Za analizu je korišćena krv sakupljana u vakutejnere sa heparinom.
Analizirano je 984 uzoraka. Koncentracija metala je određena metodom masene
spektrometrije sa induktivno spregnutom plazmom (7700x, Agilent, USA), sa oktopol
reaktivnim sistemom i „micro‐flow“ raspršivačem. Prosečna starost ispitanika iznosila je
37,210,8 godina. Referentne vrednosti ispitivanih metala u krvi, prikazane kao 95. percentil
su 0,95 µg/L, 0,62 µg/L i 1,46 µg/L za hrom, kobalt i nikl, redom, su u dobroj korelaciji sa
vrednostima dobijenim u biomonitoring studijama sprovedenim u Evropi. Istraživanje
uticaja individualnih faktora je pokazalo da je hrom izmeren u značajno nižim
koncentracijama kod stanovništva srpske nacionalnosti, da su nivoi kobalta u krvi žena
značajno viši i da se nivoi kobalta i nikla povećavaju sa starenjem kod oba pola. Obrazovanje
i ekonomski status, pušenje cigareta i bavljenje sportom ne utiču statistički značajno na
nivoe ovih metala u krvi.

AB  - Oral anticoagulants are a group of drugs used for the prevention and treatment of venous thrombosis and venous thromboembolism. For the last ten years, direct oral anticoagulants (DOAC) have been available and are equally effective, but significantly safer than vitamin K antagonists. In the case of an overdose, their most important side effect is still bleeding. Due to their widespread use, as well as increased toxicological importance there is a need to develop an analytical method for the determination of DOAC in biological material. The aim of this paper was to establish a method for the quantification of apixaban as one of the representatives of DOAC. The methodology of the study included the measurement of apixaban in the plasma of patients treated in the intensive care unit. Plasma apixaban concentrations were determined by LC-MS/MS technique using carbamazepine as an internal standard. Obtained validation parameters indicate that the introduced method is sensitive, reliable, precise and accurate. Using this method, apixaban can be quickly and easily detected and quantified in plasma in patients who are suspected of overdosing with this drug.

AB  - The major goal of this study was to estimate the correlations and dose-response pattern between the measured blood toxic metals (cadmium (Cd), mercury (Hg), chromium (Cr), nickel (Ni))/metalloid (arsenic (As)) and serum insulin level by conducting Benchmark dose (BMD) analysis of human data. The study involved 435 non-occupationally exposed individuals (217 men and 218 women). The samples were collected at health care institutions in Belgrade, Serbia, from January 2019 to May 2021. Blood sample preparation was conducted by microwave digestion. Cd was measured by graphite furnace atomic absorption spectrophotometry (GF-AAS), while inductively coupled plasma-mass spectrometry (ICP-MS) was used to measure Hg, Ni, Cr and As. BMD analysis of insulin levels represented as quantal data was done using the PROAST software version 70.1 (model averaging methodology, BMD response: 10%). In the male population, there was no correlation between toxic metal/metalloid concentrations and insulin level. However, in the female population/whole population, a high positive correlation for As and Hg, and a strong negative correlation for Ni and measured serum insulin level was established. BMD modelling revealed quantitative associations between blood toxic metal/metalloid concentrations and serum insulin levels. All the estimated BMD intervals were wide except the one for As, reflecting a high degree of confidence in the estimations and possible role of As as a metabolic disruptor. These results indicate that, in the case of As blood concentrations, even values higher than BMD (BMDL): 3.27 (1.26) (male population), 2.79 (0.771) (female population), or 1.18 (2.96) μg/L (whole population) might contribute to a 10% higher risk of insulin level alterations, meaning 10% higher risk of blood insulin increasing from within reference range to above reference range. The obtained results contribute to the current body of knowledge on the use of BMD modelling for analysing 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.

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  - Valproic acid (VPA) is antiepileptic drug with a long history of clinical use,
increasingly applied in the treatment of various diseases (bipolar disorder, migraine
prophylaxis, etc). Due to significant inter-individual differences VPA concentration is often
measured in the purpose of therapeutic drug monitoring (TDM) (1). Acute poisonings with
this drug represent a significant problem. According to the American Association of Poison
Control Centers, there has been VPA poisoning incidence increase in the last 20 years.
Reports from the National Poison Control Center in Belgrade list VPA as one of the three
most common causes of antiepileptic drugs intoxications (2). This paper aimed to develop a
modern analytical method for VPA quantification in patient plasma. UPLC/MS method with
fast and simple sample preparation has been validated. After protein precipitation, VPA was
extracted from 100 μL plasma using HLB cartridges. Caprylic acid solution was used as
internal standard. Chromatographic separation was achieved on C18 column (1.8 μm, 2.1 X
150 mm) with gradient elution at constant mobile phase flow. Good peak resolution was
achieved (Rt VPA - 4.73 min, Rt ISTD - 4.94 min). Validation was performed according European
Medicines Agency recommendations. Based on statistical analysism it was shown that the
method is precise, accurate, specific, sensitive and linearity is confirmed in a wide range of
concentrations (1-250 mg / L). Advantages of this method are simple preparation procedure
from a small amount of sample, without prior derivatization and short duration of analysis,
which fully satisfies the needs of TDM and urgent toxicological analyses.
AB  - Valproinska kiselina (VK) je lek iz grupe antiepileptika sa dugom istorijom kliničke
upotrebe, koji se, osim u terapiji epilepsije, poslednjih decenija sve više koristi u terapiji
različitih bolesti (bipolarni poremećaj, profilaksa migrene itd). Zbog značajnih
interindividualnih varijacija, koncentracija VK se često određuje u svrhe terapijskog praćenja
leka (TDM – Therapeutic Drug Monitoring) (1). S druge strane, akutna trovanja ovim lekom
predstavljaju značajan problem. Prema podacima Američkih centara za kontrolu trovanja
došlo je do povećanja incidence trovanja VK u poslednjih 20 godina, dok izveštaji
Nacionalnog centra za kontrolu trovanja u Beogradu navode VK kao jedan od tri najčešća
uzročnika trovanja kada su u pitanju intoksikacije antiepilepticima (2). Cilj ovoga rada je
razvoj savremene analitičke metode za određivanje koncentracije VK u plazmi pacijenata.
Validovana je UPLC/MS metoda koja podrazumeva brzu i jednostavnu pripremu uzorka.
Nakon precipitacije proteina, izvršena je ekstrakcija iz 100 μL plazme uz pomoć HLB
kertridža. Kao interni standard korišćen je rastvor kaprilne kiseline. Hromatografsko
razdvajanje je postignuto na C18 koloni (1,8 μm, 2,1 X 150 mm) gradijentnim eluiranjem pri
konstantnom protoku mobilne faze. Postignuta je dobra rezolucija pikova (Rt VK - 4,73 min,
Rt ISTD - 4,94 min). Validacija je izvedena prema preporukama Evropske agencije za lekove, a
na osnovu statističke analize je pokazano da je metoda precizna, tačna, specifična, osetljiva i
potvrđena je linearnost u širokom opsegu koncentracija (1-250 mg/L). Prednosti ove
metode su jednostavan način pripreme iz male količine uzorka, bez prethodne derivatizacije,
i kratko vreme trajanja analize, što u potpunosti zadovoljava potrebe TDM-a i urgentnih
toksikoloških analiza.

AB  - Exposure to lead (Pb) is still rising concern worldwide, having in mind that even low-dose exposure can induce various harmful effects. Thus, in-depth knowledge of the targets of Pb toxicity and corresponding mechanisms is essential. In the presented study, the six groups (male Wistar rats, n = 6) received 0.1; 0.5; 1; 3; 7; 15 mg Pb/kg body weight/day for 28 days, each day by oral gavage, while the control group received distilled water only. All animals were sacrificed 24 h after the treatment, and blood was collected for the analysis of hematological, biochemical, oxidative status and essential elements levels. An external and internal dose-response relationship was performed using PROASTweb 70.1 software. The results showed that low doses of Pb affect hematological parameters and lipid profile after 28 days. The possible mechanisms at examined Pb dose levels were a decrease in SOD, O2•􀀀 and Cu and an increase in Zn levels. The dose-dependent nature of changes in cholesterol, HDL cholesterol, O2.-, SOD, AOPP in serum and hemoglobin, Fe, Zn, Cu in blood were obtained in this study. The most sensitive parameters that were alerted are Cu blood levels (BMDL5: 1.4 ng/kg b.w./day) and SOD activity (BMDL5: 0.5 μg/kg b.w./day). The presented results provide information that may be useful in further assessing the health risks of low-level Pb exposure.

AB  - According to theWorld Health Organization, in 2015, the Serbian population ranked among the highest ones in Europe in terms of smoking habit: 44.3%males and 36.2%females aged 18–64 smoked tobacco. In the last 7 years, 25%of total mortality inmen and 9%in women from Serbia were associated with smoking. Tobacco smoking is one of the most important sources of exposure to many toxic substances in general population. Our study confirmed higher blood levels of two toxic metals, cadmium and lead, in the blood of smokers (3.5 and 1.5 times higher than in non-smokers, respectively). Furthermore, smoking habits, such as number of smoked cigarettes per day, smoking period and cigarette type, along with age, were shown to influence these metals’ blood concentration. Higher blood levels of Cd and Pb were found in smokers consuming more than 10 cigarettes per day for more than 10 years. The present study also highlighted the importance of the controlled tobacco production, since it was shown that consumption of illicit tobacco could manifold the exposure to toxic metals that can subsequently increase the frequency of related diseases as well.

AB  - Immunochromatographic strips for urine drug screening tests (UDSTs) are common and very suitable for drug abuse monitoring, but are also highly susceptible to adulterants kept in the household, which can significantly alter test results. The aim of this study was to see how some of these common adulterants affect UDST results in practice and whether they can be detected by sample validity tests with pH and URIT 11G test strips. To this end we added household chemicals (acids, alkalis, oxidizing agents, surfactants, and miscellaneous substances) to urine samples positive for amphetamine, 3,4-methylenedioxymethamphetamine (MDMA), tetrahydrocannabinol, heroin, cocaine, or benzodiazepines (diazepam or alprazolam) and tested them with one-component immunochromatographic UDST strips. The UDST for cocaine resisted adulteration the most, while the cannabis test produced the most false negative results. The most potent adulterant that barely changed the physiological properties of urine specimens and therefore escaped adulteration detection was vinegar. Besides lemon juice, it produced the most false negative test results. In conclusion, some urine adulterants, such as vinegar, could pass urine specimen validity test and remain undetected by laboratory testing. Our findings raise concern about this issue of preventing urine tampering and call for better control at sampling, privacy concerns notwithstanding, and better sample validity tests.
AB  - Preliminarna analiza prisutnosti psihoaktivnih tvari u mokraći pomoću imunokromatografskih testnih traka (UDST) našla je primjenu u mnogim područjima. Iako vrlo prikladne u kontroli zloporabe droga, testne su trake iznimno osjetljive na sredstva za patvorenje (adulterante) kao što su kućne kemikalije, što može značajno promijeniti rezultate testa. Cilj ovoga istraživanja bio je ispitati potencijal uobičajeno korištenih adulteranata kada je riječ o utjecaju na rezultate probira na prisutnost psihoaktivnih tvari u mokraći uporabom UDST-a. Ispitivane kemikalije (kiseline, lužine, oksidirajuća sredstva, površinski aktivne tvari i druge) dodane su uzorcima urina u kojima je, tekućinskom kromatografijom – masenom spektrometrijom (LC-MS) prethodno potvrđena prisutnost amfetamina, 3,4-metilendioksimetamfetaina (MDMA), tetrahidrokanabinola, heroina i kokaina benzodiazepina (diazepam ili alprazolam). U ispitivanju su korištene jednokomponentne imunokromatografske testne trake. Manipulacija uzorcima urina provjeravala se pomoću pH traka, kao i biokemijskih testnih traka za semikvantitativno određivanje koncentracija endogenih tvari i specifične težine uzoraka urina pomoću testnih traka URIT 11G. Rezultati ovoga ispitivanja pokazali su da je test za detekciju kokaina u urinu najmanje osjetljiv na utjecaj ispitivanih adulteranata, a test za detekciju kanabinoida najosjetljiviji, posebice u pogledu lažno negativnih rezultata. Najsnažniji adulterant koji je utjecao na rezultate testa a nije promijenio fiziološke parametre urina je alkoholni ocat. Osim soka od limuna, alkoholni ocat dodan u urin proizveo je najveći broj negativnih ishoda testiranja. Može se zaključiti da značajan broj adulteranata utječe na rezultate testa i da je moguće da neki od njih, poput alkoholnoga octa, mogu proći neopaženo pri kontroli valjanosti uzorka. Ovi nalazi upozoravaju na važnost strogo kontroliranog okruženja za uzorkovanje urina kako bi se spriječile manipulacije.
