AB  - Liverworts are characterized by a high content of bioactive compounds reported to show antimicrobial, anticancer, and antioxidant properties. In this study, the biological effects of the methanol extract of the liverwort Pellia endiviifolia and its constituents, bis-bibenzyls perrottetin E, 10′-hydroxyperrottetin E, and 10,10′-dihydroxyperrottetin E, were investigated using human peripheral blood cells as a model system. The assessment of the investigated compounds comprised testing their genotoxicity, apoptotic potential, and redox modulating activities. The genotoxicity testing indicated that medium (25 µM) and high concentrations (100 µM) of the investigated compounds displayed genotoxic and antiproliferative effects in human lymphocytes as revealed by significant, concentration-dependent enhancement of the micronuclei incidence and decrease in the cytokinesis-block proliferation index compared to the control (P <.001). Analysis of leukocyte apoptosis showed a substantial potential of all investigated compounds to induce apoptosis, which was not concentration-dependent. The P endiviifolia extract and perrottetin E demonstrated considerable pro-apoptotic potential, even at the lowest concentration (1 µM) applied. Evaluation of the redox modulating effects, which comprised measuring erythrocyte catalase activity and the lymphocyte malondialdehyde level, showed that the investigated compounds did not induce oxidative stress in human peripheral blood cells (P >.05). The observed genotoxic, antiproliferative, and proapoptotic effects of the investigated compounds make them suitable for further comprehensive studies related to their possible applications as anticancer agents.

AB  - Two silver–polyaniline/polyvinylpyrrolidone (Ag–PANI/PVP) nanocomposites were prepared using in situ integration of silver nanoparticles (AgNPs) during oxidative aniline polymerization, accelerated by the presence of PVP, which as well minimized the risk of particle agglomeration and macroscopic precipitation. Both nanocomposites have similar silver content (∼44 wt% Ag) but different morphological features of AgNPs (spheres/triangles) and polymers (granular/wrinkling pattern). Several spectroscopic, macroscopic, and analytical techniques, microscopy, and surface analysis methods have been used to analyze their physical and chemical properties. Investigation of their antimicrobial potential and possible application as an effective weapon against indicator microbial strains, E. coli, S. aureus, and C. albicans, has shown inhibition of microbial growth by more than 90%, even at low composite concentrations (5 ppm) and short contact time (4 h). A biosafety assessment of Ag–PANI/PVP that comprised testing the genotoxicity and redox modulating activity was performed using human peripheral blood cells as a model system. The obtained results have shown that the investigated Ag–PANI/PVP exhibited significant prooxidant and cytostatic effects (p < 0.05) with no apparent potential to induce DNA damage. Although precautions should be taken to protect human health, the significant antimicrobial efficiency of Ag–PANI/PVP makes it suitable for further studies and applications in non-medical areas, such as wastewater treatment.

AB  - Acetylcholinesterase (AChE) inhibitors are important in the treatment of neurodegenerative diseases. Two inhibitors,12-tungstosilicic acid (WSiA) and 12-tungstophosphoric acid (WPA), which have polyoxometalate(POM) type structure, have been shown to inhibit AChE activity in nM concentration. Circular dichroism andtryptophan fluorescence spectroscopy demonstrated that the AChE inhibition was not accompanied by significantchanges in the secondary structure of the enzyme. The molecular docking approach has revealed a newallosteric binding site, termed β-allosteric site (β-AS), which is considered responsible for the inhibition of AChEby POMs. To the best of our knowledge, this is the first study reporting a new allosteric site that is consideredresponsible for AChE inhibition by voluminous and negatively charged molecules such as POMs. The selectedPOMs were further subjected to genotoxicity testing using human peripheral blood cells as a model system. Itwas shown that WSiA and WPA induced a mild cytostatic but not genotoxic effects in human lymphocytes, whichindicates their potential to be used as medicinal drugs. The identification of non-toxic compounds capable ofbinding to an allosteric site that so far has not been considered responsible for enzyme inhibition could befundamental for the development of new drug design strategies and the discovery of more efficient AChEmodulators.

AB  - The simple green method for synthesis of stable L-Methionine (L-Met) capped silver (Ag@LM NPs) and gold (Au@LM NPs) nanoparticles (NPs) without adding any additional reduction agent or stabilizer was developed. Colloidal dispersions were characterized by UV–Vis spectrophotometry. The size and spherical shape of NPs were evaluated by transmission electron microscopy. Their surface covering was confirmed by atomic force microscopy, Fourier transform infrared spectroscopy, dynamic light scattering, and zeta potential measurements. Density functional theory calculations pointed that the preferential adsorption mode of L-Met on both Ag and Au surfaces was a vertical binding geometry via –NH2 group, while horizontal binding mode via [sbnd]S[sbnd] and –NH2 groups is also possible. The genotoxicity (evaluated by the micronucleus assay) of NPs, as well as their effects on some oxidative stress parameters (catalase activity, malondialdehyde level), were assessed in vitro using human peripheral blood cells as a model system. The influence of NPs on the morphology of lymphocyte cells studied using atomic force microscopy revealed that the membrane of cells remained unaffected after the treatment with NPs. When considering the effects of NPs on catalase activity and malondialdehyde level, neither particle type promoted oxidative stress. However, the treatment of lymphocytes with Ag@LM NPs induced a concentration-dependent enhancement of the micronuclei incidence and suppression of the cell proliferation while Au@LM NPs promoted cell proliferation, with no significant effects on micronuclei formation. The Ag@LM NPs were more prone to induce DNA damage than Au@LM NPs, which makes the latter type more suitable for further studies in nano-medicine. © 2019

AB  - UV-C irradiation is widely used in the food industry. However, the health effects from dietary exposure to the irradiated pesticide residues retained in foodstuffs are underestimated. In this study, technical chlorpyrifos (TCPF) and its oil in water (EW) and emulsifiable concentrate (EC) formulations were irradiated by UV-C, and their photodegradation products were subjected to toxicity assessment, including determination of acetylcholinesterase (AChE) activity, genotoxicity and oxidative stress using human blood cells as a model system. Toxicity studies were performed using the chlorpyrifos concentrations in the range of those proposed as the maximum residue levels in plant commodities. TCPF, EW and EC photodegradation products induced DNA damage and oxidative stress, and their genotoxicity did not decrease as a function of irradiation time. Irradiated TCPF and EC are more potent AChE inhibitors than irradiated EW. Accordingly, the application of UV-C irradiation must be considered when processing the plants previously treated with chlorpyrifos formulations. © 2018 Elsevier Ltd

AB  - Citrate-capped gold nanoparticles (AuNPs) were functionalized with three distinct antitumor gold(III) complexes, e.g., [Au(N,N)(OH)2][PF6], where (N,N)=2,2′-bipyridine; [Au(C,N)(AcO)2], where (C,N)=deprotonated 6-(1,1-dimethylbenzyl)-pyridine; [Au(C,N,N)(OH)][PF6], where (C,N,N)=deprotonated 6-(1,1-dimethylbenzyl)-2,2′-bipyridine, to assess the chance of tracking their subcellular distribution by atomic force microscopy (AFM), and surface enhanced Raman spectroscopy (SERS) techniques. An extensive physicochemical characterization of the formed conjugates was, thus, carried out by applying a variety of methods (density functional theory—DFT, UV/Vis spectrophotometry, AFM, Raman spectroscopy, and SERS). The resulting gold(III) complexes/AuNPs conjugates turned out to be pretty stable. Interestingly, they exhibited a dramatically increased resonance intensity in the Raman spectra induced by AuNPs. For testing the use of the functionalized AuNPs for biosensing, their distribution in the nuclear, cytosolic, and membrane cell fractions obtained from human lymphocytes was investigated by AFM and SERS. The conjugates were detected in the membrane and nuclear cell fractions but not in the cytosol. The AFM method confirmed that conjugates induced changes in the morphology and nanostructure of the membrane and nuclear fractions. The obtained results point out that the conjugates formed between AuNPs and gold(III) complexes may be used as a tool for tracking metallodrug distribution in the different cell fractions.

AB  - The complexity of the admixture dynamics that shaped American populations is unveiled by Ongaro et al., where genetic data for more than 12,000 individuals from the continents are investigated. This study evaluates the dramatic impact of events after the colonial era, revealing a spatial and temporal heterogeneity and mirroring historical records. © 2019 Elsevier Ltd The human genetic diversity of the Americas has been affected by several events of gene flow that have continued since the colonial era and the Atlantic slave trade. Moreover, multiple waves of migration followed by local admixture occurred in the last two centuries, the impact of which has been largely unexplored. Here, we compiled a genome-wide dataset of ∼12,000 individuals from twelve American countries and ∼6,000 individuals from worldwide populations and applied haplotype-based methods to investigate how historical movements from outside the New World affected (1) the genetic structure, (2) the admixture profile, (3) the demographic history, and (4) sex-biased gene-flow dynamics of the Americas. We revealed a high degree of complexity underlying the genetic contribution of European and African populations in North and South America, from both geographic and temporal perspectives, identifying previously unreported sources related to Italy, the Middle East, and to specific regions of Africa. © 2019 Elsevier Ltd

AB  - In recent years, the search for effective anticancer compounds based on transition metal complexes has been the focus of medical investigations. The synergy between the ruthenium(II) and N-alkylphenothiazine counter-ions (chlorpromazine hydrochloride, thioridazine hydrochloride and trifluoperazine dihydrochloride, respectively) through the formation of three different complexes (1–3) was investigated. We explored whether the selected counter-ions and complexes might affect redox homeostasis and genome integrity of normal human blood cells, and induce an inhibition of Na+/K+-ATPase and AChE at pharmacologically relevant doses. Our results have shown that counter-ions and complexes did not affect the activity of Na+/K+-ATPase, while AChE activity was inhibited in a dose-dependent manner. All investigated compounds disturbed the viability and redox homeostasis of lymphocytes. Complexes 1 and 2 displayed potent cytotoxic and prooxidant action while complex 3 behaved as a weaker genotoxic inducer. Still, the tested complexes appeared to be less genotoxic and more cytostatic than the corresponding counter-ions. The effects of selected complexes were also tested in PC12 and U2OS cancer cells with special attention being given to the ability of phenothiazines to affect dopamine D2 receptors. Using the confocal laser scanning microscopy, we observed that all the complexes reduced cell viability. Although all investigated complexes have been bound to the dopamine receptor D2-eGFP, only complex 3 reduced its surface density and increased its lateral mobility in investigated cell lines. Albeit the role of alternative targets for complex 3 cannot be ruled out, its effects should be further examined as potential treatment strategy against cancer cells that overexpress D2.

AB  - Copper nanoparticles (Cu NPs) have proven to own excellent antimicrobial efficacy, but the problems of easy oxidation and aggregation limit their practical application. Here, nanocomposite based on polyaniline (PANI) and Cu NPs solved this problem and brought additional physicochemical properties that are markedly advantageous for antimicrobial applications. Current work exploits this potential, to examine its time- and concentration-dependent antimicrobial activity, employing E. coli, S. aureus, and C. albicans as a model microbial species. Regarding the presence of polaronic charge carriers in the fibrous polyaniline network, effects of Cu NPs’ size and their partially oxidized surfaces (the data were confirmed by HRTEM, FESEM, XRD, Raman and XPS analysis), as well as rapid copper ions release, Cu-PANI nanocomposite showed efficient bactericidal and fungicidal activities at the concentrations ≤1 ppm, within the incubation time of 2 h. Beside the quantitative analysis, the high levels of cellular disruption for all tested microbes were evidenced by atomic force microscopy. Moreover, the minimum inhibitory and bactericidal concentrations of the Cu-PANI nanocomposite were lower than those reported for other nanocomposites. Using such low concentrations is recognized as a good way to avoid its toxicity toward the environment. For this purpose, Cu-PANI nanocomposite is tested for its genotoxicity and influence on the oxidative status of the human cells in vitro.

AB  - It is known that some bacterial species are more resilient to different kinds of irradiation due to the naturally developed protective mechanisms and compounds such as pigments. On the other hand, reasoned tissue engineering using plasma remains a critical task and requires very precise control of plasma parameters in order to mitigate its potential detrimental effects. Here we isolated a natural protective agent, microbially produced undecylprodigiosin ((52)-4-methoxy-5-[(5-undecy1-1H-pyrrol2-yl)methylenel-1H,5H-2,2-bipyrrole), and investigated its effects on human blood cells independently and in combination with plasma. Two apprOaches were applied; the first, undecylprodigiosin (UP pigment) was added to the blood cultures, which then were exposed to plasma (pre-treatment); and the second- the blood cultures were exposed to plasma and then treated with pigment (post-treatment). The interactions of plasma and UP pigment with blood cells were investigated by conducting a series of biological tests providing the information regarding their genotoxicity, cytotoxicity and redox modulating activities. The exposure of cells to plasma induced oxidative stress as well as certain genotoxic and cytotoxic effects seen as elevated micronuclei incidence, decreased cell proliferation and enhanced apoptosis. In blood cultures treated with UP pigment alone, we found that both cytotoxic and protective effects could be induced depending on the concentration used. The highest UP pigment concentration increased lipid peroxidation and the incidence of micronuclei by more than 70% with maximal suppression of cell proliferation. On the contrary, we found that the lowest UP pigment concentration displayed protective effects. In combined treatments with plasma and UP pigment, we found that UP pigment could provide spatial shielding to plasma exposure. In the pre-treatment approach, the incidence of micronuclei was reduced by 35.52% compared to control while malondialdehyde level decreased by 36% indicating a significant mitigation of membrane damage induced by plasma. These results open perspectives for utilizing UP pigment for protection against overexposures in the field of plasma medicine. (C) 2016 Elsevier GmbH. All rights reserved.

AB  - Undecylprodigiosin pigment (UPP) is reported to display cytotoxic activity towards various types of tumours. Nevertheless, its efficacy in modifying the cellular response to ionising radiation is still unknown. In this study, the radiomodulating effects of UPP were investigated. The effects of UPP were assessed in vitro by treating cultures of human peripheral blood with UPP and ionising radiation using two treatment regimens, the UPP pre-irradiation treatment and UPP post-irradiation treatment. The activity of UPP was investigated evaluating its effects on the radiation-induced micronuclei formation, cell proliferation, and induction of apoptosis. The redox modulating effects of UPP were examined measuring the catalase activity and the level of malondialdehyde, as a measure of oxidative stress. The results showed that UPP effects on cellular response to ionising radiation depend on its concentration and the timing of its administration. At low concentration, the UPP displayed radioprotective effects in. gamma-irradiated human lymphocytes while at higher concentrations, it acted as a radiosensitiser enhancing either mitotic catastrophe or apoptosis depending on the treatment regimen. The UPP modified redox processes in cells, particularly when it was employed prior to gamma-irradiation. Our data highlight the importance of further research of the potential of UPP to sensitize tumour cells to radiation therapy by inhibiting pathways that lead to treatment resistance.

AB  - Background: Acetylcholinesterase (AChE) is involved in the termination of impulse transmission by rapid hydrolysis of the neurotransmitter acetylcholine in numerous cholinergic pathways in the central and peripheral nervous systems. The enzyme inactivation leads to acetylcholine accumulation, hyperstimulation of nicotinic and muscarinic receptors, and disrupted neurotransmission. Hence, acetylcholinesterase inhibitors, interacting with the enzyme as their primary target, are applied as relevant drugs for different neurodegenerative diseases (such as Alzheimers and Parkinsons) as well as toxins. At the same time, there are increasing evidence that in non-neuronal context, AChE is involved in the regulation of cell proliferation, differentiation, apoptosis and cell-cell interaction. An irregular expression of AChE has been found in different types of tumors, suggesting the involvement of AChE in the regulation of tumor development. Having all this in mind, there is a possibility that some AChE inhibitors could be used as anti-cancer agents. Objective: This contribution will discuss a broad range of possible application of different AChE inhibitors as drugs, from well-known anti-Alzheimers disease drugs to their use in cancer treatment in future. Emphasis will be put on various known AChE inhibitors classes, whose application as drugs could be controversy, as well as on newly investigated natural products, which can also modulate AChE activity. Conclusion: It is not clear a patient treated for neurodegenerative condition prone to increased risk for some types of cancer and vice versa. This is necessary to keep in mind during rational drug design process for all therapies, which are based on AChE as a target molecule.

AB  - Photo-responsive drug release systems are promising for drug delivery applications due to many benefits compared to conventional chemotherapy such as targeted, controlled release of a drug and reduced toxicity to healthy tissues. In this work, we report synthesis of the nanocomposite system based on carrier TiO2 nanoparticles and potential anticancer ruthenium complex, with light controllable release properties. Nanocomposite system showed biological activity and induced the generation of free radicals, which are implied in the efficient cell killing. The drug release tests demonstrated sustained release of the transition metal complex from the surface implying the potency for the controlled drug delivery system. Taking into account photoactivity of the Ru-complex, in the next step we have investigated the influence of green light on the rate of the complex release, and the results showed dependence of the Ru-complex release from the surface of TiO2 nanoparticles on the applied laser energy. Therefore, these characteristics make this nanocomposite system promising for the photo-responsive chemotherapy.

AB  - Ruthenium compounds are highly regarded as metallo-drug candidates. Many studies have focused their attention on the interaction between ruthenium complexes with their possible biological targets. The interaction of ruthenium complexes with transport proteins, enzymes and peptides is of great importance for understanding their biodistribution and mechanism of action, therefore, the development of an anti-cancer therapy involving ruthenium complexes has recently shifted from DNA targeting towards protein targeting. With the aim of gaining insight into possible interactions between ruthenium complexes with biologically relevant proteins, we have studied the interaction of cis-dichlorobis(2,2-bipyridyl-4,4-dicarboxylic acid)ruthenium(II) complex [Ru(II)(dcbpy)(2)Cl-2], which previously showed good potency in photo-dynamic chemotherapy, with bovine serum albumin (BSA), phospholipase A(2) (PLA(2)) and glutathione (GSH). Binding constants and possible number of binding sites to mentioned proteins and peptide are investigated by ultraviolet-visible spectroscopy and Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI TOF MS). The complex binding affinities were in the following order: PLA(2) GT BSA GT GSH. Moreover, genotoxic profile of the complex, tested on peripheral blood lymphocytes as a model system, was also promising.

AB  - Myeloperoxidase (MPO) is an important member of the haem peroxidase - cyclooxygenase superfamily. This enzyme is physiologically expressed in circulating neutrophils, monocytes and some tissue macrophages including microglia. MPO plays an essential role in the antimicrobial and antiviral system of humans. The microbicidal activity of MPO exists due to its capability to oxidize halide and pseudohalide ions (Cl-, Br-, I- and SCN-) by H2O2, thereby producing respective hypohalous acids (HOX). During the phagocytosis of pathogens, azurophilic granules release their content together with MPO into phagolysosomes. On the other hand, MPO can be discharged outside the phagocytes. Due to this, tissue damage during inflammation is greatly promoted by MPO-derived oxidants. Regarding its activity, MPO is a key factor in a great number of conditions within the group of cardiovascular diseases, inflammatory diseases, neurodegenerative diseases, kidney diseases and immune-mediated diseases. Therefore, MPO and its downstream inflammatory pathways might be attractive targets for both prognostic and therapeutic intervention in the prophylaxis of all mentioned illnesses. Nowadays, structure and reaction mechanism of MPO are known, which enable rational strategy in the development of specific MPO inhibitors that still preserve MPO activity during host defense from bacteria, but hinder pathophysiologically persistent activation of MPO. Various methods for MPO activity inhibition and unfavorable effects of MPO-derived oxidants remodeling will be discussed. Emphasis will be put on various known inhibitors, as well as on newly investigated natural products, which can also inhibit MPO activity.

AB  - Fanconi anemia (FA) is a rare genetically heterogeneous disorder associated with bone marrow failure, birth defects and cancer susceptibility. Apart from the disease-causing mutations in FANC genes, the identification of specific DNA variations, such as single nucleotide polymorphisms (SNPs), in other candidate genes may lead to a better clinical description of this condition enabling individualized treatment with improvement of the prognosis. In this study, we have assessed 95 SNPs located in 52 key genes involved in base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), double strand break (DSB) repair and cell cycle control using a DNA repair chip (Asper Biotech, Estonia) which includes most of the common variants for the candidate genes. The SNP genotyping was performed in five FA-D2 patients and in one FA-A patient. The polymorphisms studied were synonymous (n=10), nonsynonymous (missense) (n=52) and in non-coding regions of the genome (introns and 5 and 3 untranslated regions (UTR)) (n=33). Polymorphisms found at the homozygous state are selected for further analysis. Our results have shown a significant inter-individual variability among patients in the type and the frequency of SNPs and also elucidate the need for further studies of polymorphisms located in ATM, APEX APE 1, XRCC1, ERCC2, MSH3, PARP4, NBS1, BARD1, CDKN1B, TP53 and TP53BP1 which may be of great importance for better clinical description of FA. In addition, the present report recommends the use of SNPs as predictive and prognostic genetic markers to individualize therapy of FA patients.

AB  - To investigate genetic subtypes of inherited bone marrow failure syndrome Fanconi anemia (FA) in Sebia. FA-D2 subtype was found to be the most frequent genetic subtype among investigated FA patients; specific observations of FA-D2 phenotype are pointed out. Several biological endpoints of FA cells in vitro such as radiation-induced level of lymphocyte micronuclei (radiosensitivity), base line and radiation induced level of the DNA double strand breaks (DSBs), leukocyte apoptosis, and telomere capping function were assessed. The results indicate that all FA-D2 patients display radioresistant in vitro response, which is seen as significantly reduced yield of radiation-induced micronuclei. On the contrary, FA-A patients display radiosensitive in vitro response seen as increased number of radiation-induced micronuclei (MN). A massive elimination of irradiated cells via apoptosis is found in both FA-A and FA-D2 subtypes. In FA-A subtype apoptosis positively relates with the yield of radiation-induced MN, whereas in FA-D2 subtype apoptosis relates with a high percentage of cells carrying dysfunctional telomeres. The present results unequivocally demonstrate that cytokinesis-block micronucleus (CBMN) assay and analyses of telomere capping function can be used to distinguish FA-D2 and FA-A complementation groups. Considering all biological endpoints were analyzed, it can be concluded that all FA patients are radiosensitive, regardless of their complementation group. Thus, using CBMN test and telomere capping function analysis can discriminate FA-A from FA-D2 complementation groups, which could be important for assessment the conditioning regimens prior to bone marrow transplantation.

AB  - Purpose: As the Fanconi anemia (FA) pathway is required for appropriate cell cycle progression through mitosis and the completion of cell division, the aim of the present study was to determine the destiny of FA cells after irradiation in vitro and to elucidate any difference in radiosensitivity between FA and control cells. Materials and methods: Analyses of phosphorylated histone H2AX (gamma-H2AX) foci, micronuclei formation and cell cycle analysis were performed in unirradiated (0 min) and irradiated primary FA fibroblasts and in a control group at different post-irradiation times (30 min, 2 h, 5 h and 24 h). Results: The accumulation of gamma-H2AX foci in irradiated FA fibroblasts was observed. At 24 h post-irradiation, 57% of FA cells were gamma-H2AX foci-positive, significantly higher than in the control (p LT 0.01). The cell cycle analysis has shown the transient G2/M arrest in irradiated FA fibroblasts. The portion of cells in the G2/M phase showed initial increase at 30 min post-irradiation and afterwards decreased over time reaching the pretreatment level 24 h after irradiation. Irradiated FA fibroblasts progressed to abnormal mitosis, as is shown by the production of cells with different nuclear morphologies from binucleated to multinucleated surrounded with micronuclei, and also by a high percentage of foci-positive micronuclei. The majority of radiation-induced micronuclei were gamma-H2AX foci-positive, indicating that radiation-induced micronuclei contain fragments of damaged chromosomes. In contrast, in the control group, most of the micronuclei were classified as gamma-H2AX foci-negative, which indicates that cells with unrepaired damage were blocked before entering mitosis. Conclusion: The results clearly indicate that mitotic catastrophe might be an important cell-death mechanism involved in the response of FA fibroblasts to ionizing radiation.

AB  - We use human primary fibroblasts for comparing plasma and gamma rays induced DNA damage. In both cases, DNA strand breaks occur, but of fundamentally different nature. Unlike gamma exposure, contact with plasma predominantly leads to single strand breaks and base-damages, while double strand breaks are mainly consequence of the cell repair mechanisms. Different cell signaling mechanisms are detected confirming this (ataxia telangiectasia mutated - ATM and ataxia telangiectasia and Rad3 related - ATR, respectively). The effective plasma doses can be tuned to match the typical therapeutic doses of 2Gy. Tailoring the effective dose through plasma power and duration of the treatment enables safety precautions mainly by inducing apoptosis and consequently reduced frequency of micronuclei.

AB  - Contemporary inhabitants of the Balkan Peninsula belong to several ethnic groups of diverse cultural background. In this study, three ethnic groups from Bosnia and Herzegovina - Bosniacs, Bosnian Croats and Bosnian Serbs - as well as the populations of Serbians, Croatians, Macedonians from the former Yugoslav Republic of Macedonia, Montenegrins and Kosovars have been characterized for the genetic variation of 660 000 genome-wide autosomal single nucleotide polymorphisms and for haploid markers. New autosomal data of the 70 individuals together with previously published data of 20 individuals from the populations of the Western Balkan region in a context of 695 samples of global range have been analysed. Comparison of the variation data of autosomal and haploid lineages of the studied Western Balkan populations reveals a concordance of the data in both sets and the genetic uniformity of the studied populations, especially of Western South-Slavic speakers. The genetic variation of Western Balkan populations reveals the continuity between the Middle East and Europe via the Balkan region and supports the scenario that one of the major routes of ancient gene flows and admixture went through the Balkan Peninsula.

AB  - Herbal preparation Chlamyfin was investigated for its total polyphenol content, 2,2-diphenyl-1picrylhydrazyl (DPPH) scavenging activity, and anti-inflammatory and genotoxic properties. A high total polyphenol content provided evidence of high DPPH radical scavenging activity (IC50 = 4.96 +/- 0.23 mu g/ml). Analysis of the electrochemical behavior of Chlamyfin indicated high reducing ability, i.e., high antioxidant capacity, in agreement with the DPPH test. Analysis of myeloperoxidase (MPO) inhibition by Chlamyfin suggested anti-inflammatory action (IC50 values of 5.40 mu g/ml and 4.45 i_tg/m1 for an incubation time of 10 and 30 min, respectively). For genotoxic assessment, oxidative stress was induced by irradiation of peripheral whole blood with gamma-radiation in vitro. In the presence of Chlamyfin, reduced incidence of micronuclei without disturbance to the proliferative potential of cells was evidenced in both irradiated and unirradiated samples, indicating its genoprotective properties. It was shown that Chlamyfm, in addition to its bactericidal effect, also possesses strong antioxidant, anti-inflammatory and anti-genotoxic properties.

AB  - Fanconi anemia (FA) is a rare cancer-prone genetic disease characterized by impaired oxygen metabolism and defects in DNA damage repair. Response of FA cells to ionizing radiation has been an issue intensively debated in the literature. To study in vitro radiosensitivity in patients suffering from FA and their parents (heterozygous carriers), we determined radiation-induced leukocyte apoptosis using flow cytometry. As TP53 gene is involved in the control of apoptosis, we studied its status in FA lymphocytes using dual colour fluorescence in situ hybridization (FISH). FA patients and female heterozygous carriers display radiosensitive response to ionizing radiation seen as abnormal elimination of cells via apoptosis. By employment of FISH, the TP53 allele loss in FA lymphocytes was not observed. In diseases related to oxidative stress, determination of radiation-induced apoptosis is the method of choice for testing the radiosensitivity.

AB  - Fanconi anemia (FA) is a rare genetically heterogeneous disease characterized by developmental abnormalities, progressive bone marrow failure, and cancer susceptibility. We examined spontaneous, diepoxybutane (DEB)-induced and radiation-induced sister chromatid exchanges (SCEs) in wholeblood lymphocyte cultures of bone marrow failure (BMF) patients including Fanconi anemia, mothers of affected individuals, and healthy controls. The baseline frequency of SCE in FA cells was similar to that observed in controls. However, in response to DEB SCE frequencies in FA patients and their mothers were significantly increased compared to both non-FA BMF families and healthy controls. In response to ionizing radiation, cells displayed increased frequency of SCE, but no differences between FA patients and non-FA BMF patients were seen. Our data confirm and expand previous findings by showing that SCE induced by DEB can be used as an adjunct diagnostic test not only for FA patients, but also for female heterozygous carriers, at least for complementation groups FANCA and FANCD2.
