AB  - Dry olive leaf extract (DOLE) and its active component oleuropein (OLE) were applied as reducing and stabilizing agents to prepare colloidal 20–25 nm silver nanoparticles (Ag NPs). The Ag NPs were characterized using transmission electron microscopy, X-ray diffraction analysis, and absorption spectroscopy. The cytotoxic actions of coated Ag NPs, and their inorganic and organic components, were examined against trophoblast cells and human peripheral blood lymphocytes (PBLs), Gram-positive, Gram-negative bacteria, and yeast. The genotoxic potential was evaluated in PBLs in vitro with the comet assay. Ag/DOLE and Ag/OLE induced cytotoxic effects in both types of cells after 24 h exposure when silver concentrations were 0.025–0.2 mM. However, the most pronounced cytotoxicity exhibits Ag/OLE. Both colloids also caused reduced ROS production in both cell types at 0.1 mM and 0.2 mM, while bare Ag NPs did not alter ROS levels at any of the conditions. Functionalized Ag/DOLE and Ag/OLE did not show genotoxic effects in PBLs, while bare AgNPs increased DNA damage significantly only at 0.2 mM. Regarding the antimicrobial effects, the Ag/OLE had MIC values for all evaluated microorganisms from 0.0625 to less than 0.0312 mM. Also, the antimicrobial effect of Ag/DOLE was significantly higher on Gram-negative bacteria and yeast than on Gram-positive bacteria. Obtained results indicate that Ag/OLE induced the most pronounced biological effects, beneficial for its application as an antimicrobial agent, but with potential risks from exposure to high concentrations that could induce cytotoxicity in healthy human cells.

AB  - The antibacterial performance and cytotoxic examination of in situ prepared silver nanoparticles (Ag NPs), on inorganic-organic hybrid nanopowder consisting of zirconium dioxide nanoparticles (ZrO2 NPs) and dihydroquercetin (DHQ), was performed against Gram (−) bacteria Escherichia coli and Gram (+) bacteria Staphylococcus aureus, as well as against human cervical cancer cells HeLa and healthy MRC-5 human cells. The surface modification of ZrO2 NPs, synthesized by the sol-gel method, with DHQ leads to the interfacial charge transfer (ICT) complex formation indicated by the appearance of absorption in the visible spectral range. The prepared samples were thoroughly characterized (TEM, XRD, reflection spectroscopy), and, in addition, the spectroscopic observations are supported by the density functional theory (DFT) calculations using a cluster model. The concentration- and time-dependent antibacterial tests indicated a complete reduction of bacterial species, E. coli and S. aureus, for all investigated concentrations of silver (0.10, 0.25, and 0.50 mg/mL) after 24 h of contact. On the other side, the functionalized ZrO2 NPs with DHQ, before and after deposition of Ag NPs, do not display a significant decrease in the viability of HeLa MRC-5 cells in any of the used concentrations compared to the control.

AB  - More than 30 types of amyloids are linked to close to 50 diseases in humans, the most prom- inent being Alzheimer’s disease (AD). AD is brain-related local amyloidosis, while another amyloidosis, such as AA amyloidosis, tends to be more systemic. Therefore, we need to know more about the biological entities’ influencing these amyloidosis processes. However, there is currently no support system developed specifically to handle this extraordinarily complex and demanding task. To acquire a systematic view of amyloidosis and how this may be relevant to the brain and other organs, we needed a means to explore "amyloid net- work systems" that may underly processes that leads to an amyloid-related disease. In this regard, we developed the DES-Amyloidoses knowledgebase (KB) to obtain fast and rele- vant information regarding the biological network related to amyloid proteins/peptides and amyloid-related diseases. This KB contains information obtained through text and data min- ing of available scientific literature and other public repositories. The information compiled into the DES-Amyloidoses system based on 19 topic-specific dictionaries resulted in 796,409 associations between terms from these dictionaries. Users can explore this infor- mation through various options, including enriched concepts, enriched pairs, and semantic similarity. We show the usefulness of the KB using an example focused on inflammasome- amyloid associations. To our knowledge, this is the only KB dedicated to human amyloid- related diseases derived primarily through literature text mining and complemented by data mining that provides a novel way of exploring information relevant to amyloidoses.

AB  - Increased levels of oxidative stress and oxidative DNA damage are common features in the pathology of Alzheimer’s disease (AD) found in neurons and peripheral cells like peripheral blood lymphocytes (PBL). Natural products such as strawberry cultivar Alba are an important source of bioactive nutrients that could help in lowering both the oxidative stress and DNA damage levels. The objective was to estimate the effects of Alba extract on DNA damage in peripheral blood lymphocytes of sporadic AD (aged 60–84 years) patients, and healthy elderly (aged 69–83 years) and young (aged 21–30 years) individuals in in vitro conditions. Comet assay was used as a sensitive technique for the evaluation of PBL DNA damage levels. Reduction of basal DNA damage level in PBL was shown in the young group after the incubation with Alba extract ranging from 25 to 200 μg/ml, with 100 μg/ml being the most effective concentration. Selected Alba extract of 100 μg/ml was further used for PBL treatment of AD and healthy elderly age matched group, displaying potential to significantly attenuate DNA damage levels in both groups (p <.05). Alba extract displayed biological activity against oxidative DNA damage, suggesting that its functional ingredients may have beneficial health effects. Practical applications: The data obtained in this preliminary study displayed that strawberry Alba extract is efficient against DNA damage induced by endogenous and exogenous oxidative stress in peripheral blood lymphocytes of Alzheimer`s disease in vitro. An active area of future research of Alba cultivar should be to determine the trials in in vivo systems. Our findings also suggest that Alba cultivar’s functional ingredients potentially may have beneficial health effects in AD. © 2021 Wiley Periodicals LLC.

AB  - To remedy carotid artery stenosis and prevent stroke surgical intervention is commonly used, and the gold standard being carotid endarterectomy (CEA). During CEA cerebrovascular hemoglobin oxygen saturation decreases and when this decrease reaches critical levels it leads to cerebral hypoxia that causes neuronal damage. One of the proposed mechanism that affects changes during CEA and contribute to acute brain ischemia (ABI) is oxidative stress. The increased production of reactive oxygen species and reactive nitrogen species during ABI may cause an unregulated inflammatory response and further lead to structural and functional injury of neurons. Antioxidant activity are involved in the protection against neuronal damage after cerebral ischemia. We hypothesized that neuronal injury and poor outcomes in patients undergoing CEA may be results of oxidative stress that disturbed function of antioxidant enzymes and contributed to the DNA damage in lymphocytes. © 2019 The Authors

AB  - Alzheimer’s disease (AD) is a neurodegenerative disease that affects millions of individuals worldwide and can occur relatively early or later in life. It is well known that genetic components, such as the amyloid precursor protein gene on chromosome 21, are fundamental in early-onset AD (EOAD). To date, however, only the apolipoprotein E4 (ApoE4) gene has been proved to be a genetic risk factor for late-onset AD (LOAD). In recent years, despite the hypothesis that many additional unidentified genes are likely to play a role in AD development, it is surprising that additional gene polymorphisms associated with LOAD have failed to come to light. In this review, we examine the role of X chromosome epigenetics and, based upon GWAS studies, the PCDHX11 gene. Furthermore, we explore other genetic risk factors of AD that involve X-chromosome epigenetics. © Copyright © 2020 Bajic, Essack, Zivkovic, Stewart, Zafirovic, Bajic, Gojobori, Isenovic and Spremo-Potparevic.

To date, however, only the apolipoprotein E4 (ApoE4) gene has been proved to be a genetic risk factor for late-onset AD (LOAD). In recent years, despite the hypothesis that many additional unidentified genes are likely to play a role in AD development, it is surprising that additional gene polymorphisms associated with LOAD have failed to come to light. In this review, we examine the role of X chromosome epigenetics and, based upon GWAS studies, the PCDHX11 gene. Furthermore, we explore other genetic risk factors of AD that involve X-chromosome epigenetics. © Copyright © 2020 Bajic, Essack, Zivkovic, Stewart, Zafirovic, Bajic, Gojobori, Isenovic and Spremo-Potparevic.",

AB  - Objective. Inosine 5'-monophosphate dehydrogenase (IMPDH) activity in cancer cells is increased. Tiazofurin selectively inhibits the activity of IMPDH, and it has been granted for the treatment of different cancers and new viral diseases. Its widespread use was limited because exposure to tiazofurin under certain circumstances was found to have a higher frequency of severe non-hematologic toxicity. Therefore, the objective of this study was to examine genotoxic action and inducement of DNA damage of tiazofurin using the comet assay. Methods. The ability of tiazofurin to induce DNA damage was evaluated using single-cell gel electrophoresis (SCGE) technique/comet assay. Human whole blood cells were exposed to three final concentrations of tiazofurin (1µM/mL, 2 µM/mL, and 5 µM/mL) for 30 min in vitro. Results. Our results indicate that tiazofurin produced a significant level of DNA damage on whole blood cells after 30 min of exposure vs. control. All tested concentrations were significantly comet-forming, in a concentration-dependent manner. Conclusion. Our investigation on the tiazofurin-treated cells and their relationship to the formation of DNA damage demonstrated that the genotoxic effect was induced after exposure to tiazofurin under described conditions.
AB  - Cilj. Aktivnost inozin 5’-monofosfat dehidrogenaze(IMPDH) povećana je u ćelijama karcinoma. Tiazofurin selektivno inhibira aktivnost IMPDH i odobren je za lečenje različitih karcinoma i novih virusnih bolesti. Njegova široko rasprostranjena upotreba bila je ograničena jer je utvrđenoda je izloženost tiazofurinu pod određenim okolnostima imala veću incidencu ozbiljne nehematološke toksičnosti. Stoga je cilj ove studije bio da se pomoću komet testa ispita genotoksično delovanje i izazivanje DNK oštećenja tiazofurinom. Metode. Sposobnost tiazofurina da izazove DNK oštećenje procenjena je primenom elektroforeze DNK pojedinačnih ćelija (SCGE) / komet testa. Ćelije pune krvi su bile izložene trima konačnim koncentracijama tiazofurina (1µM/mL, 2 µM/mL, and 5 µM/mL) tokom 30 minuta in vitro. Rezultati. Naši rezultati ukazuju na to da je tiazofurin proizveo značajan nivo DNK oštećenja na ćelijama pune krvi nakon 30 minuta izlaganja u odnosu na kontrolu. Sve ispitivane koncentracije su dovele do značajnog nastanka kometa, pri čemu je nivo oštećenja rastao s koncentracijom. Zaključak. Naše istraživanje ćelija tretiranih tiazofurinom i njihova reakcija na izazivanje DNK oštećenja pokazalo je da je tiazofurin ispoljio genotoksični efekat pod opisanim uslovima.

AB  - The health benefits of natural products have long been recognized. Consumption of dietary compounds such as supplements provides an alternative source of natural products to those obtained from the diet. There is a growing concern regarding the possible side effects of using different food supplements simultaneously, since their possible interactions are less known. For the first time, we have tested genotoxic and antigenotoxic effects of Biochaga, in combination with dihydroquercetin. No genotoxic effect on whole blood cells was observed within individual treatment of Biochaga (250 μ g/mL, 500 μ g/mL and 1000 μ g/mL) and dihydroquercetin (100 μ g/mL, 250 μ g/mL and 500 μ g/mL), nor in combination. Afterwards, antigenotoxic potency of both supplements against hydrogen peroxide- (H 2 O 2 -) induced DNA damage to whole blood cells (WBC) was assessed, using the comet assay. Biochaga and dihydroquercetin displayed a strong potential to attenuate H 2 O 2 -induced damage on DNA in cells at all tested concentrations, with a statistical significance ( p < 0.05 ), whereas Biochaga at the dose of 500 μ g/mL in combination with dihydroquercetin 500 μ g/mL was most prominent. Biochaga in combination with dihydroquercetin is able to protect genomic material from oxidative damage induced by hydrogen peroxide in vitro .

AB  - Objective. Prooxidants and antioxidants affect the oxidative balance at the intracellular level. Oxidative stress is a consequence of the overproduction of prooxidants and is caused by disturbances in the balance of oxidative reduction processes. Non-enzymatic low molecular weight antioxidants can be introduced into the body through food. Cordyceps sinensis (C. sinensis) is a medicinal fungus used in traditional Chinese medicine, with rich content of vitamins, various polysaccharides, and many nucleosides. The aim of this study is to evaluate the antioxidant capacity of the dietary supplement C. sinensis. Methods. The capacity of the hydroxyl radical scavenger activity, the total antioxidant activity of FRAP (Ferric Reducing Antioxidant Power) and the DPPH (2,2-diphenyl-1picrylhydrazyl) scavenger activity were measured. Results. C. sinensis at the tested concentrations of 0.0078-2.00 mg/mL had a pronounced ability to remove hydroxyl radicals with IC50 of 0.5 mg/mL, while at concentrations (0.0078-10.00 mg / mL) it showed a moderate reducing ability. C sinensis showed no ability to remove DPPH radicals. Conclusion. C. sinensis effectively removes hydroxyl radicals, for which the body does not have adequate antioxidant protection, so we can include it in the group of free radical scavengers.
AB  - Cilj. Prooksidansi i antioksidansi utiču na oksidativnu ravnotežu na intracelularnom nivou. Oksidativni stres je posledica prekomerne produkcije prooksidanasa i nastaje usled poremećaja u ravnoteži oksido-redukcionih procesa. Neenzimski antioksidansi male molekulske mase mogu se uneti u organizam preko hrane. Cordyceps sinensis (C. sinensis) lekovita je gljiva koja se koristi u tradicionalnoj kineskoj medicini, ima bogat sadržaj vitamina, raznih polisaharida, kao i mnogih nukleozida. Cilj istraživanja ove studije bila je evaluacija antioksidativnog kapaciteta dijetetskog suplementa C. sinensis. Metode. Mereni su kapacitet "skevindžer" aktivnosti hidroksil radikala, ukupna antioksidativna aktivnost primenom FRAP (Ferric Reducing Antioxidant Power) metode i DPPH (2,2-difenil-1-pikrilhidrazil) - skevindžer aktivnost. Rezultati. C. sinensis je u ispitivanim koncentracijama 0,0078-2,00 mg/mL imao izraženu sposobnost uklanjanja hidroskil radikala, čija je IC50 iznosila 0,5 mg/mL, dok je u koncentracijama 0,0078-10,00 mg/mL pokazao umerenu redukcionu sposobnost. C. sinensis nije pokazao sposobnost uklanjanja DPPH radikala. Zaključak. C. sinensis efikasno neutrališe hidroksilne radikale, za koje organizam nema adekvatnu antioksidativnu zaštitu pa ga možemo uvrstiti u grupu potencijalnih protektora od slobodnih radikala.

AB  - The acute toxicity of surface-modified TiO2 nanoparticles (NPs) with caffeic acid (CA) was compared with those of its separate constituents (free CA and bare TiO2 NPs) upon their oral administration in laboratory mice. Prior to in vivo experiments, the interfacial charge transfer (ICT) complex between surface Ti atoms and CA is thoroughly characterized. Composition and stability constants of ICT complex were determined using Job's method and Banesi-Hildebrand analysis, respectively. The experimental data were supported with quantum chemical calculations based on density functional theory (DFT). Acute toxicity signs, including biochemical alterations and extensive histopathological changes in the liver tissue of mice were detected 14 days after oral administration of bare TiO2 NPs. However, the clinical signs of toxicity, the fractional contribution of organs, biochemical parameters of liver and kidney function, and histopathological changes in liver upon treatment with surface-modified TiO2 NPs with CA were not observed. Also, the genotoxic potential of the ICT complex and its constituents were evaluated in leukocytes of whole blood cells in vivo by comet assay. Both, bare and surface-modified TiO2 NPs did not display DNA damaging effect in time frame of 24 h upon their oral administration in mice.

AB  - Manuka honey has been widely researched regarding its biological properties, in particular its antimicrobial and antioxidant capacities. We tested the genotoxic and genoprotective properties of Manuka honey, ranging from 25–1000 μg/mL, by performing an in vitro comet assay after exposure to human whole blood. No genotoxic effect on whole blood cells was observed within the tested concentration range (p = 0.154). Then, the antigenotoxic potency of Manuka honey against oxidative DNA damage to whole blood cells was assessed. Prior to Manuka honey treatment a modest decrease of H2O2-induced DNA damage was detected in cells, with no statistical significance (p = 0.087). Post-treatment, Manuka honey displayed a stronger potential to attenuate damaged cells at all tested concentrations, with a statistical significant difference (p < 0.001), where concentrations of 25 and 100 μg/mL were most efficient. Manuka honey exhibited a marked potential to protect DNA of whole blood cells from oxidative damage induced by hydrogen peroxide in vitro.

AB  - The antigenotoxic and antioxidative properties of surface-modified TiO2 nanoparticles (NPs) with ascorbic acid (AA) were compared with those of constituents (free AA and bare TiO2 NPs). Colloids consisting of the TiO2 NPs with anatase crystal structure were prepared by acidic hydrolysis of TiCl4. The synthesized TiO2 NPs were characterized using transmission electron microscopy and X-ray diffraction analysis. The charge transfer (CT) complex formation between surface Ti atoms and AA is indicated by immediate appearance of red color. Composition and stability constants of CT complex were determined using Jobs method and Banesi-Hildebrand analysis, respectively. The surface structure of CT complex was determined from infra-red spectra of free and bound AA to the surface Ti atoms. The experimental data were supported with quantum chemical calculations based on density functional theory (DFT). The antigenotoxic potential of CT complex was evaluated in leukocytes of whole blood cells in vitro by comet assay method. For evaluation of antioxidant properties, total antioxidant status (TAS) and total oxidant status (TOS) were determined in human serum pool in vitro. The presented results indicate that bare TiO2 NPs have more pronounced antigenotoxic effects in comparison with either surface-modified TiO2 NPs with AA or free AA. No significant differences between the antigenotoxic and antioxidative properties of free and bound AA on the TiO2 NPs were noticed in the investigated concentration range. It seems that surface-modified TiO2 NPs with AA and/or similar compounds can be used to maintain its beneficial activities. (C) 2017 Elsevier B.V. All rights reserved.

AB  - Poly (lactic-co-glycolic acid) (PLGA)-based materials are widely investigated for drug delivery and tissue engineering applications. Despite their popularity the genotoxic potential of PLGA has not been investigated. In this study, the comet assay, a sensitive assay for DNA damage, was used to evaluate potential genotoxicity in model cell types exposed to PLGA microspheres. Human umbilical vein endothelial cells (HUVECs) and mesenchymal stem cells (MSCs) cells were exposed to PLGA microspheres (0.4-6mg/mL) and DNA damage assessed at 24h, 4days, and 7days. DNA damage was not identified after 24h. However, after 4 and 7 days of exposure to 2 and 6mg/mL of PLGA microspheres a significant elevation of DNA damage in both cell types was observed. The PLGA microspheres did not exhibit any cytotoxic effects on the cells under the conditions tested. Our results suggest that PLGA may have a genotoxic effect on cells. A broader investigation of the PLGA genotoxic profile in biological systems is needed. (c) 2016 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 105A: 284-291, 2017.

AB  - The ability of Agaricus blazei mushroom in its dried and powdered mycelial form was evaluated for its antigenotoxic properties for the first time. Antigenotoxic effects in human peripheral blood cells against H2O2-induced DNA damage were examined in pretreatment and posttreatment protocol by comet assay. The results showed better antigenotoxic properties of Agaricus blazei on the interventional level, respectively, after treatment. Agaricus blazei in concentration of 250 mu g/mL after treatment was most efficient in regard to its action against DNA damage. The evaluation of repair kinetics showed decrease in H2O2 induced DNA damage 15min after the application of A. blazei, reaching the maximum potency after 30 min. Analysis of antioxidant properties of Agaricus blazei revealed strong center dot OH scavenging properties and moderate reducing power, while its DPPH scavenging ability was weak. In regard to our findings, we can conclude that our preliminary results demonstrated antigenotoxic properties of Agaricus blazei and its strong center dot OH scavenging ability. Mechanisms underlying its properties should be further evaluated in in vivo studies.

AB  - The CaNa(2)EDTA chelation therapy is often practiced with antioxidant supplementation. Dry olive leaf extract (DOLE) is natural product with antioxidant and DNA protective properties. The effects of DOLE on the levels of DNA damage were investigated ex vivo in peripheral blood lymphocytes (PBLs) of 19 workers occupationally exposed to lead (Pb), before and after CaNa(2)EDTA chelation therapy. POLE demonstrated pronounced radical scavenging activity in concentrations GT = 1 mg/mL, and showed no genotoxicity per se, in concentrations 0.125-1 mg/mL. The level of DNA damage in PBLs of workers before chelation therapy was elevated (24.21 +/- 14.26) compared to controls (6.0 +/- 3.37). The incubation of PBLs before chelation therapy with selected concentration of DOLE lead to a severe increase of DNA damage (64.03 +/- 20.96), exhibiting prooxidant rather than antioxidant effect. After the five-day CaNa2EDTA chelation regimen, DNA damage in PBLs of workers decreased (8.26 +/- 4.62) significantly compared to baseline. Treatment of PBLs with DOLE after chelation, again produced high level of damage (41.82 +/- 23.17) and the acute prooxidant effects of DOLE remained, but, DNA damage was less severe than before chelation. The DOLE exhibits prooxidant effect in presence of Pb in lymphocytes of exposed workers, and its effect is less pronounced following the removal of Pb after standard chelation therapy.

AB  - The essential oils of genus Seseli are known for their beneficial biological activities and could present novel targets in the development of safe and effective preparations of plant products. The objective was to test the essential oils of different parts of Seseli rigidum from two natural habitats for potential genotoxic and antigenotoxic activities against H2O2-induced DNA damage in human whole blood cells in vitro, by the comet assay. The essential oil analysis showed a high falcarinol content in oil from the root, while oils of the fruit and aerial parts contained a-pinene as the main compound. Genotoxicity was not detected at any of the concentrations of the essential oils from the three parts of the plant from localities I and II. Although the antioxidant activity (established by the FRAP and DPPH tests) of the investigated oils was low, all oils demonstrated a strong antigenotoxic effect against H2O2-induced damage post-treatment, when the oils were applied after the oxidant. Based on the lack of pretreatment activity and the post-treatment reduction in DNA damage, the antigenotoxic effect of S. rigidum essential oils was probably based on the stimulation of DNA repair mechanisms. Environmental conditions did not affect the antigenotoxic properties of the oils. In conclusion, our results revealed the antigenotoxic properties of S. rigidum essential oils and appropriate and safe doses with beneficial effects under the described conditions.

AB  - The effects of co-administration of dry olive leaf extract (DOLE) with standard methotrexate (MTX) therapy on the parameters of cell damage and inflammation in patients with early and long-term rheumatoid arthritis (RA) were evaluated at baseline, 3 and 6weeks. Patients were assigned to groups: the early phase RA group on MTX monotherapy (E MTX), and the two RA groups that received co-treatment with DOLE and MTX: early (E MTX+DOLE) and long-term phase patients (L-t MTX+ DOLE). Baseline values indicated increased parameters of cell damage and disruption of redox balance in all groups. After three weeks the E MTX+DOLE group maintained high catalase activity, exhibited decrease of lipid peroxidation and protein damage indicatorsthiols and nitrites, while levels of DNA damage and pro-inflammatory interleukin-6 were significantly reduced. In E MTX group catalase activity remained unaltered while significant lipid peroxidation and DNA damage reductions were seen only after six weeks. L-t MTX+DOLE group showed only modest alterations of cell damage parameters during six weeks. Combined administration of DOLE with MTX contributes to faster reduction of cell damage, restores oxidative balance and improves interleukin-6 suppression during high disease activity in early phase RA, but not in long term patients.

AB  - Context Cordyceps sinensis (C sinensis) is a well-known, traditional, Chinese medicinal mushroom, valued for its beneficial properties for human health. C sinensis has been reported to have immunomodulatory, anticancer, antiaging, antioxidant and anti-inflammatory activity. Despite potential medicinal benefits, no previously published reports are available about the genotoxicity or antigenotoxicity of C sinensis, as detected by comet assay. Objective The objective of the study was to evaluate both the genotoxic and antigenotoxic potential of an extract of C sinensis (CS extract) in human peripheral blood cells. Design The research team designed a pilot study. Setting The study was conducted at the Center for Biological Research, University of Belgrade, in Belgrade, Serbia. Participants Participants were 6 healthy individuals (2 males and 4 females), between the ages of 20 and 45 y, recruited on a voluntary basis, who provided heparinized, peripheral blood samples. Intervention Four concentrations of the CS extract125 mu g/mL, 250 mu g/mL, 500 mu g/mL, and 1000 mu g/mL-were used in the treatment of tested blood cells from the blood samples. Three independent procedures were performed: (1) a genotoxicity assessment, (2) an antigenotoxicity assessment for pretreatment of human cells with the CS extract prior to their exposure to hydrogen peroxide (H2O2) (ie, an evaluation of the benefits of the CS extract as a preventive agent); and (3) posttreatment of human cells with the CS extract after their exposure to H2O2 (ie, an evaluation of the benefits of the CS extract as an interventional agent). Outcome Measures Cells were graded by eye inspection into 5 classes, depending on the extent of DNA damage, representing: (1) class A-undamaged cells with no tail ( LT 5% damaged DNA); (2) class B-low-level damage (5%-20%); (3) class C-medium-level damage (20%-40%); (4) class D-high-level damage (40%-95%), and (5) class E-total destruction ( GT 95%). Results The CS extract proved to be nongenotoxic because no induced DNA damage was detected at all tested concentrations. For the antigenotoxicity assessment of the pretreatment with the CS extract, only the 1000-mu g/mL concentration showed a significant decrease in the number of cells exhibiting H2O2-induced DNA damage. For the posttreatment, the CS extract exhibited antigenotoxic potential by attenuating H2O2-induced DNA damage at all concentrations tested. The evaluation of repair kinetics showed a decrease in DNA-damaged cells 15 min after the application of the CS extract, reaching a maximum potency after 45 min. Conclusions The results indicated that C sinensis can be used as a postapplicative agent that counteracts the effect of oxidative stress. The resulting reduction in DNA damage might be related to its scavenging properties and stimulation of DNA repair.

AB  - Ganoderma lucidum is traditionally used in Eastern medicine to preserve vitality, promote longevity, and treat disease. It possesses immunomodulatory, antitumor, antimicrobial, and antiaging activities, among others, but one of the most important is its antioxidant property, which is the basis for other effects, because free radicals trigger many diseases. The substrate commonly used for commercial cultivation of G. lucidum is not environmenwas to analyze the effect of substrate composition on the bioactivity of G. lucidum basidiocarps. G. lucidum was cultivated on 2 different substrates: (1) a mixture of wheat straw, grapevine branches, and wheat bran, and (2) wheat straw. Commercial fruiting bodies, cultivated on oak sawdust, were used as the control. 1,1- diphenyl- 2- picrylhydrazyl (DPPH) The comet test was performed to detect the degree of DNA damage in the cells that were exposed to G. lucidum extracts before and after the effect of oxidants. Higher antioxidative potential was observed for the extract of G. lucidum basidiocarps cultivated on wheat straw compared with that from the mixed substrate and especially with commercial ones. The alternatively cultivated basidiocarps also showed stronger antigenotoxic potential compared with commercial ones. The study showed that fruiting bodies produced on wheat straw, one of the most accessible and cheapest crop residues, are more potent antioxidant and antigenotoxic agents than commercially cultivated ones.

AB  - Alzheimers disease (AD) is a complex and progressive neurodegenerative disorder, and represents the most common form of dementia. The number of people affected by AD is estimated to be doubled by the year of 2050, and more than 100 million people worldwide will be affected by this disease. Still, there is no reliable diagnostic test which would indicate pre-symptomatic conditions or an increased risk of developing AD. The only drugs approved by the FDA belong to the cholinesterase inhibitors (ChEI) group, such as donepezil, rivastigmine, galantamine and memantine that belongs to a class of drugs named receptor NMDA antagonists. Most mainstream pharmacotherapeutic approaches act by slowing the progression of the condition rather than to treat or prevent the cause of AD. In this review we are presenting literature data from recent research related to new avenues in the classical approach to prevention and treatment of AD.

AB  - Neurons are postmitotic cells that are in permanent cell cycle arrest. However, components of the cell cycle machinery that are expressed in Alzheimers disease (AD) neurons are showing features of a cycling cell and those attributed to a postmitotic cell as well. Furthermore, the unique physiological operations taking place in neurons, ascribed to core cell cycle regulators are also key regulators in cell division. Functions of these cell cycle regulators include neuronal migration, axonal elongation, axon pruning, dendrite morphogenesis and synaptic maturation and plasticity. In this review, we focus on cohesion and cohesion related proteins in reference to their neuronal functions and how impaired centromere/cohesion dynamics may connect cell cycle dysfunction to aneuploidy in AD.

AB  - Prema podacima Svetske zdravstvene organizacije, 15 miliona ljudi godišnje doživi moždani udar. Najčešći uzročnik moždanog udara je ishemija mozga, koja se dešava u skoro 85% slučajeva. Moždana ishemija izazvana tromboembolijskim događajima definiše se kao trajno ili prolazno smanjenje cirkulacije krvi, što za posledicu ima nedostatak kiseonika, glukoze i ostalih važnih nutritijenata, dovodeći postepeno do metaboličkih promena i apoptoze ćelija. Tokom operativnih zahvata kao što je karotidna endarterektomija (CEA) može doći do hipoksično-ishemičnog stanja mozga ili akutne ishemije mozga (ABI), kao i do samog moždanog udara. Glavni uzrok ABI u toku CEA je cerebralna hipoperfuzija koja je uzrokovana klemovanjem karotidne arterije, pri čemu dolazi do hipoksije, što može predstavljati jedan od okidača za niz fizioloških odgovora organizma, među kojima je oslobađanje različitih medijatora inflamacije. Jedan od medijatora inflamacije je i azot monoksid (NO), slobodni radikal koji pored mnogobrojnih fizioloških efekata ima važnu ulogu i u samom imunom odgovoru organizma. Međutim, NO može biti veoma štetan i svojim delovanjem dovesti do oštećenja ćelija i tkiva. Nedostatak podataka u literaturi o ulozi endotelne NOS (eNOS) i inducibilne NOS (iNOS) tokom CEA, kao i mehanizama njihove regulacije u stanjima ishemije, ukazuju na pravac kojim treba da se usmere buduća istraživanja. Poznavanje molekularnih mehanizama regulacije aktivnosti i ekspresije iNOS, svakako će pomoći razvoju novih terapijskih strategija u tretmanu štetnih efekata produkcije slobodnih radikala, pre svega nekontrolisane produkcije NO.
AB  - According to the World Health Organization, 15 million people per year are affected by stroke. The most common cause of stroke is brain ischemia, which occurs in almost 85% of cases. Ischemia caused by thromboembolism is defined as permanently or temporarily decreased blood flow which prevents an adequate delivery of oxygen, glucose and other important nutrients, leading progressively to metabolic changes and cell apoptosis. Carotid endarterectomy (CEA) can cause hypoxic - ischemic states of the brain or acute brain ischemia (ABI) leading eventually to stroke. The main cause of ABI as a result of CEA is cerebral hypoperfusion caused by clamping of carotid arteries, when hypoxia occurs.. Hypoxia per se is one of the triggers of complex physiological responses in the body, including the release of various mediators of inflammation. One of these inflammatory mediators is nitric oxide (NO), a free radical which has numerous physiological effects and also plays an important role in the immune response of the organism. However, NO may be very harmful and cause cell and tissue damage. The lack of literature data on the role of endothelial NOS (eNOS) and inducible NOS (iNOS) during CEA, as well as the mechanisms of their regulation in ischemic conditions, suggest that intensifying future research in this field is very important. An insight into molecular mechanisms of iNOS activity and expression regulation will certainly help to develop new therapeutic strategies for treating harmful effects of free radicals, especially uncontrolled production of NO.

AB  - Alzheimers disease (AD) is a multi factorial disease, related to the loss of neurons and synapses in cerebral cortex and subcortical structures, leading to degenerative changes and atrophy. Despite abundance of facts related to AD and its pathology, the only drugs used in the prevention and treatment are those from the cholinesterase inhibitors group. However, there is growing evidence that a non-classical therapeutic approach in the treatment of AD has beneficial effects. In this review we summarized recent literature data related to the non-classical drugs for the treatment of AD predominantly used in clinical testing, such as amyloid aggregation inhibitors, beta-sheet breakers, antioxidants, estrogens and immunotherapeutics.

AB  - X-chromosome instability has been a long established feature in Alzheimers disease ( AD). Premature centromere division and aneuploidy of the X-chromosome has been found in peripheral blood lymphocytes and neuronal tissue in female AD patients. Interestingly, only one chromosome of the X pair has been affected. These results raised a question, Is the X-chromosome inactivation pattern altered in peripheral blood lymphocytes ofwomen affected by AD? To address this question, we analyzed the methylation status of androgen receptor promoter which may show us any deviation from the 50 : 50% X inactivation status in peripheral blood lymphocytes ofwomen with AD. Our results showed skewed inactivation patterns ( GT 90%). These findings suggest that an epigenetic alteration on the inactivation centers of the X-chromosome (or skewing) relates not only to aging, by might be a novel property that could account for the higher incidence of AD in women.

AB  - Lead induced oxidative cellular damage and long-term persistence of associated adverse effects increases risk of late-onset diseases. CaNa(2)EDTA chelation is known to remove contaminating metals and to reduce free radical production. The objective was to investigate the impact of chelation therapy on modulation of lead induced cellular damage, restoration of altered enzyme activities and lipid homeostasis in peripheral blood of workers exposed to lead, by comparing the selected biomarkers obtained prior and after five-day CaNa(2)EDTA chelation intervention. The group of smelting factory workers diagnosed with lead intoxication and current lead exposure 5.8 +/- 1.2 years were administered five-day CaNa(2)EDTA chelation. Elevated baseline activity of antioxidant enzymes Cu, Zn-SOD and CAT as well as depleted thiols and increased protein degradation products-carbonyl groups and nitrites, pointing to Pb induced oxidative damage, were restored toward normal values following the treatment. Lead showed inhibitor potency on both RBC AChE and BChE in exposed workers, and chelation re-established the activity of BChE, while RBC AChE remained unaffected. Also, genotoxic effect of lead detected in peripheral blood lymphocytes was significantly decreased after therapy, exhibiting 18.9% DNA damage reduction. Administration of chelation reversed the depressed activity of serum PON 1 and significantly decreased lipid peroxidation detected by the post-chelation reduction of MDA levels. Lactate dehydrogenase LDF1-5 isoenzymes levels showed evident but no significant trend of restoring toward normal control values following chelation. CaNa(2)EDTA chelation ameliorates the alterations linked with Pb mediated oxidative stress, indicating possible benefits in reducing health risks associated with increased oxidative damage in lead exposed populations.
