Abstract
OBJECTIVES This study, aimed to determine and compare DNA damage in e-cigarette and HTP (IQOS) users by assessing DNA-adducts, which are biomarkers of various DNA alkylation and oxidation. METHODS For the evaluation of DNA alkylation, N3-Ethyladenine (N3-EtA) and N3-Methyladenine (N3-MeA) adducts were used. DNA oxidation was assessed using, 8-hydroxy-2'-deoxyguanosine(8-OHdG). The urinary cotinine, N3-MeA, N3-EtA, and 8-OHdG concentrations of the cigarette smokers (n:39), e-cigarette users (n:28), IQOS users (n:20), passive smokers (n:32), and nonsmokers(n:41) who lived Ankara, Turkiye were determined using, liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS In light of the detected 8-OHdG levels, e-cigarette (3.19 ng/g creatinine) and IQOS (4.38 ng/g creatinine) users had higher oxidative DNA damage than healthy nonsmokers (2.51 ng/g creatinine). Alkylated DNA-adducts were identified in the urine of e-cigarette (N3-MeA: 3.92 ng/g creatinine; N3-EtA: 0.23 ng/g creatinine) and IQOS (N3-MeA: 7.54 ng/g creatinine; N3-EtA: 0.29 ng/g creatinine) users. In the generation of N3-MeA adducts, a significant difference was found between IQOS users and e-cigarette users (p < 0.05). Also, DNA alkylation in flavored e-cigarette users (N3-MeA: 4.51 ng/g creatinine; N3-EtA: 0.27 ng/g creatinine) was higher than in non-flavored e-cigarette users (N3-MeA: 2.27 ng/g creatinine; N3-EtA: 0.06 ng/g creatinine). The highest cotinine levels were found in cigarette smokers (16.1316 ng/g creatinine). No significant difference was found when e-cigarette (1163.02 ng/g creatinine) and IQOS smokers were compared (1088.3 ng/g creatinine). CONCLUSION People who use e-cigarettes and IQOS may be at higher risk of genotoxicity than those who do not use and are not exposed to any tobacco products. Furthermore, the usage of flavoring additives in e-cigarettes contributed to additional genotoxic damage risks.

Abstract
Background Gutka chewing is the most common deleterious oral habit prevalent in the geographical distribution of the Indian subcontinent. Gutka leads to the production of numerous free radicals, which causes oxidative stress in regional oral tissues. Oxidative stress brings about the oxidation of guanine bases of DNA that generates 8-OHdG as its main byproduct. The presence of 8-OHdG can be evaluated not only in tissue but also in saliva, blood and urine. The availability of 8-OHdG in these samples is quite documented. In addition, a comparative assay of 8-ohdg DNA damage marker in multiple samples is yet to be done. Material and Methodology A sample size of 60 was divided into two groups, i.e., gutka consumers without any lesion and gutka consumers with OSMF. Ten samples each of saliva, serum and urine were collected from these two groups and healthy controls. Samples were centrifuged at 1000 RPM at 2-8°C for 15-20 minutes. A volume of 1.5 ml resultant supernatant was pipetted out in labelled Eppendorf tubes and stored at -80°C. The ELISA test was performed to measure the concentration of 8-OHdG protein in different samples at 450 nm after adding stop solution in 96-well microplate. Results 8-OHdG concentration was found to be highest in saliva followed by urine and serum. 8-OHdG concentration in serum was significantly less than that in saliva and urine (P-value <0.05). Intergroup difference in concentration of 8-OHdG of urine, saliva and serum was significant (P-value <0.05). Post hoc analysis revealed that concentration of 8-OHdG in saliva and urine was non-significantly different (P-value >0.05). Conclusion Saliva appears to be the most appropriate sample type as compared to serum and urine for the evaluation of 8-OHdG in OSMF subjects.

Abstract
8-Hydroxydeoxyguanosine (8-OHdG) is the most widely used oxidative stress biomarker of the free radical-induced oxidative damage product of DNA, which may allow a premature assessment of various diseases. This paper designs a label-free, portable biosensor device to directly detect 8-OHdG by plasma-coupled electrochemistry on a transparent and conductive indium tin oxide (ITO) electrode. We reported a flexible printed ITO electrode made from particle-free silver and carbon inks. After inkjet printing, the working electrode was sequentially assembled by gold nanotriangles (AuNTAs) and platinum nanoparticles (PtNPs). This nanomaterial-modified portable biosensor showed excellent electrochemical performance for 8-OHdG detection from 10 μg/mL to 100 μg/mL by our self-developed constant voltage source integrated circuit system. This work demonstrated a portable biosensor for simultaneously integrating nanostructure, electroconductivity, and biocompatibility to construct advanced biosensors for oxidative damage biomarkers. The proposed nanomaterial-modified ITO-based electrochemical portable device was a potential biosensor to approach 8-OHdG point-of-care testing (POCT) in various biological fluid samples, such as saliva and urine samples.

Abstract
Reactive oxygen species (ROS) are continuously produced in living cells due to metabolic and biochemical reactions and due to exposure to physical, chemical and biological agents. Excessive ROS cause oxidative stress and lead to oxidative DNA damage. Within ROS-mediated DNA lesions, 8-oxoguanine (8-oxoG) and its nucleotide 8-oxo-2'-deoxyguanosine (8-oxodG)-the guanine and deoxyguanosine oxidation products, respectively, are regarded as the most significant biomarkers for oxidative DNA damage. The quantification of 8-oxoG and 8-oxodG in urine, blood, tissue and saliva is essential, being employed to determine the overall effects of oxidative stress and to assess the risk, diagnose, and evaluate the treatment of autoimmune, inflammatory, neurodegenerative and cardiovascular diseases, diabetes, cancer and other age-related diseases. High-performance liquid chromatography with electrochemical detection (HPLC-ECD) is largely employed for 8-oxoG and 8-oxodG determination in biological samples due to its high selectivity and sensitivity, down to the femtomolar range. This review seeks to provide an exhaustive analysis of the most recent reports on the HPLC-ECD determination of 8-oxoG and 8-oxodG in cellular DNA and body fluids, which is relevant for health research.

Application of Mitochondrial and Oxidative Stress Biomarkers in the Evaluation of Neurocognitive Prognosis Following Acute Carbon Monoxide Poisoning. Metabolites 2022; 12:metabo12030201.

Abstract
Mitochondrial and oxidative stress play critical roles in the pathogenic mechanisms of carbon monoxide (CO)-induced toxicity. This study was designed to evaluate whether the serum levels of specific stress biomarkers might reflect brain injury and act as prognostic markers for the development of neurocognitive sequelae following CO poisoning. We analyzed the data from 51 adult patients admitted with acute CO poisoning and measured the serum level expression of growth differentiation factor 15 (GDF15) and fibroblast growth factor 21 (FGF21), indicators of mitochondrial stress, and 8-Oxo-2′-deoxyguanosine (8-OHdG) and malondialdehyde (MDA), indicators of oxidative stress. Serum was collected upon arrival at the hospital, at 24 h post treatment, and within 7 days of HBO2 therapy. Global Deterioration Scale scores were measured 1 month post incident and used to place the patients in either favorable or poor outcome groups. Initial serum GDF15 and 8-OHdG concentrations were significantly increased in the poor-outcome group and all four biomarkers decreased at 24 h post HBO2 therapy, and were then maintained or further decreased at the 1-week mark. Notably, the degree of change in these biomarkers between baseline and 24 h post HBO2 were significantly larger in the poor-outcome group, reflecting greater CO-associated stress, confirming that post-CO poisoning serum biomarker levels and their response to HBO2 were proportional to the initial stress. We suggest that these biomarkers accurately reflect neuronal toxicity in response to CO poisoning, which is consistent with their activity in other pathologies.

Abstract
Guanine (G) oxidation products, such as 8-hydroxy-2'-deoxyguanosine (8-OHdG) and 8-oxo-guanine (8-OXOG), have been widely studied as promising biomarkers for DNA oxidative damage. In this work, we develop a new method to detect G oxidative products released from live cells after chromium (vi) ion or hydrogen peroxide treatments by using a glass nanopipette-based flexible gold nanoelectrode (fGNE). Specific response to G oxidative products with high sensitivity can be detected from the fGNE tip through integrated electrochemical measurements and surface-enhanced Raman spectroscopy. The fGNE apex can be positioned very close to the cell membrane noninvasively because of its high flexibility and nanoscale tip size. With the assistance of the electrophoretic force, the fGNEs can effectively collect and detect the G-derived DNA damage products released from individual cells in the cell culture medium with high sensitivity.

Abstract
Lateral flow immunostrips were newly designed and a sensitive and rapid fluorometric method for the determination of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as a model target of small biomarker molecules was developed. The upconversion nanoparticles (UCNPs, NaYF4:Yb/Er core, and polyacrylic acid (PAA)-modified shell, size ~ 39 nm, excitation wavelength = 980 nm; emission wavelength = 540 nm) were employed as fluorescence signal material. The 8-OHdG antibody (Ab) was taken as the recognition probe while UCNP-labeled Ab was taken as the signal probe. Bovine serum albumin (BSA) was designed as carrier protein for 8-OHdG to form 8-OHdG-BSA conjugate as the capture probe. The lateral flow immunostrips were prepared by laminating a sample pad (glass fiber membrane), a test pad (nitrocellulose membrane), and adsorption pad (filter paper) on PVP backing. The capture probe was immobilized on the test zone while an IgG antibody taken as the control probe was immobilized on the control zone. When the signal probe and the sample were in sequence loaded on the sample pad, 8-OHdG analyte bound with the signal probe, and then the excess of the signal probe move along the strip and is collected by the capture probe on the test zone while the remnant signal probe is collected by the control probe on the control zone. The signal probe and capture probe were synthesized and characterized. The fluorescence intensity on the test zone was inversely proportional to the concentration of 8-OHdG for the quantitative determination while the fluorescence emission on the control zone was observed to validate the assay. The developed method showed a wide linear range from 0.10 to 10 nM, a quite low detection limit of 0.05 nM, small sample volume requirement (100 μL), short assay time (15 min), and good method reproducibility (RSD = 4.4%, nine immunostrips). Graphical abstract Schematic illustration of the configuration and measurement principle of lateral flow fluorescence immunostrip for 8-OHdG: (a) configuration; (b) preparation: load of capture probe (BSA-8-OHdG, 2 μL) on test zone; load of control probe (IgG Ab, 2 μL) on control zone; load of signal probe (UCNP-Ab, 16 μL) on sample pad; (c) measurement: load of sample (8-OHdG, 100 μL) on sample pad, collection, and measurement.

Abstract
Background:
8-Hydroxy-2’-deoxyguanosine (8-OHdG) has been regarded as a typical stable
biomarker of DNA oxidative damage, and its level is one of the criteria for early diagnosis of various
diseases. Considering the significance of 8-OhdG, various analytical techniques have been used for
assaying 8-OHdG but all of them suffer from basic limitations like highly expensive instrumentation,
large amount of sample requirement, complicated sample pre-treatment, tedious and time-consuming
procedures etc. However, electroanalytical sensors provide a faster, easy and sensitive means of
analyzing.
Methods:
The chitosan (CS) film provided the high electrode activity and stability which is required for
detecting 8-OHdG though direct electrochemical oxidation. Zirconia was employed because it has some
unique properties, such as high redox activity and selectivity etc. High-performance composite was
easily detected by differential pulse voltammetry at a working voltage of 0. 51 V (vs. Ag/AgCl). A rapid
and sensitive electrochemical sensor based on CS and metal oxide nanocrystalline for the determination
of 8-OHdG was established.
Results:
Under optimized experimental conditions, the peak currents of differential pulse voltammetry
increased as the concentrations of 8-OHdG increased from 10 to 200 ng·mL-1. The detection limit was
3.67 ng·mL-1 which was calculated by the S/N ratio of 3. The recoveries of the real spiked samples are
in the range between 93.2 to 105.3%.
Conclusion:
The electrochemical sensor for direct 8-OHdG determination using a new CS/zirconia
composite for GCE modification was developed and showed excellent reproducibility, stability and
sensitivity for the specific determination of 8-OHdG in real urine specimen.

Abstract
8-Hydroxy-2'-deoxyguanosine (8-OH-dG) is a principal stable marker of DNA oxidative damage. Sensitive and specific detection of 8-OH-dG is of great importance for early disease diagnosis. In this paper, we developed an electrochemiluminescence aptasensor for 8-OH-dG detection based on target induced multi-DNA release and nicking enzyme signaling amplification strategy. First, three kinds of short DNAs were aligned on the aptamers immobilized on the magnetic beads. In the presence of 8-OH-dG, the aptamer recognized and specifically bound with 8-OH-dG, leading to the release of three kinds of short DNAs and three-fold signal amplification. Then the released short DNAs hybridized with ferrocence (Fc) labeled hairpin DNA (Fc-HP) immobilized on the gold electrode to form a double strand DNA. Subsequently, nicking endonuclease (Nt.AlwI) recognized the asymmetric sequence in the dsDNA and cleaved the substrate strand (Fc-HP) into two parts, one fragments containing Fc would leave the surface of electrode. Based on the quenching effect of Fc on the electrochemiluminescence (ECL) of Ru(bpy)32+/TPA, a signal-on ECL aptasensor was developed. At the same time, three kinds of short DNAs were released again and reused to initiate the repeated cycles of hybridization-cleavage. Under double signal amplification, this aptasensor achieved a low detection of 25 fM and a wide linear range from 100 fM to 10 nM for 8-OH-dG. Besides, the amount of 8-OH-dG in urine samples derived from different people were determined with satisfactory results.

Abstract
A luminescent paper-based device for the visual detection of oxidative stress biomarkers is reported. The device consists of a polyvinylidene fluoride membrane impregnated with poly(3-alkoxy-4-methylthiophene) (PT) for colorimetric detection. 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker associated with oxidative stress, is used as a model system for validating the proposed methodology. The detection strategy is based on monitoring the changes in optical properties of PT associated with its conformational changes upon interaction with an aptamer in the presence and in the absence of 8-OHdG. Fluorometric and colorimetric monitoring revealed linear responses for 8-OHdG concentrations between 50 pM and 500 nM (∼14 pg/mL to 140 ng/mL), with limits of detection of ∼300 pM and ∼350 pM, respectively for ( n = 3). Colorimetric responses in artificial urine ascertained rapid, sensitive, and selective detection of 8-OHdG at clinically relevant (pM to nM) concentration levels. Furthermore, the proposed methodology enables point-of-care diagnostics for oxidative stress without requiring sophisticated instrumentation.

An electrochemical aptasensor for the highly sensitive detection of 8-hydroxy-2'-deoxyguanosine based on the hybridization chain reaction. Talanta 2017; 179:414-419.

Abstract
In the present work a highly sensitive and selective aptasensor was developed for the determination of 8-hydroxy-2'-deoxyguanosine (8-OH-dG) based on the hybridization chain reaction (HCR) signal amplification. It was observed that the aptamer of 8-OH-dG could hybridize with the capture DNA immobilized on the gold electrode with a sticky tail left, which initiated the HCR and led to the formation of extended dsDNA structure on the electrode surface. Then the electroactive species ([Ru(NH3)6]3+, RuHex) intercalated into the dsDNA grooves to generate the amplified signal. However, in the presence of 8-OH-dG, the aptamer containing G-rich nucleic acid sequences would be induced to form a G-quadruplex structure, which made it impossible to continue the HCR. So the detection signal will significantly decrease. Under the optimal conditions, the peak current of RuHex was linear with the logarithm of 8-OH-dG concentration in the range from 10pM to 100μM with the detection limit of 2.5pM. By integrating the merits of enzyme-free amplification power of the HCR and the inherent high sensitivity of the electrochemical technique, the prepared aptasensor not only showed high sensitivity for the detection of 8-OH-dG, but also exhibited good selectivity against to the uric acid, an important interferent in the urine sample. Particularly, the aptasensor was applied to detect 8-OH-dG in urine samples with satisfactory results.

Abstract
The phrase "oxidative-stress induced DNA damage" is commonly used in both the scientific literature and common media outlets, and is frequently linked to detrimental elements of aging as well as the onset of illnesses. Due to the growing focus on this topic, a clear need has emerged to develop a quantitative, low-cost methodology to allow for periodic monitoring of oxidative-stress induced DNA damage within individuals. Recent literature examining the link between oxidative stress and the onset of various cancers has made monitoring an even more pressing need. The mechanism of oxidative-stress induced DNA damage originates in chronic inflammation, which in turn activates various transcription factors and diseases that influence the onset of tumor development, chemoresistance, radioresistance, and other harmful cellular processes. While current technologies that aim to provide quantitative metrics require extremely expensive equipment and significant technical expertise, our laboratory has designed a low-cost methodology utilizing a combination of carbon nanotubes, paper electrodes, and immunochromatographic strips.

Abstract
Osmanthus fragrans flower extract (OFE) is an organic extract from O. fragrans flower, which exhibits neuroprotective, free radical scavenging, and antioxidant effects. Therefore, the protective effect of OFE and acteoside against aging was studied. An aging ICR mouse model was established by chronically administering d-galactose (250 mg/kg) for 8 weeks. d-galactose induced spatial learning and memory impairments that were successfully inhibited by OFE and acteoside, which could shorten escape latency, improve platform crossing times, and increase zone time. The antioxidant potential of OFE and acteoside in vivo was evaluated by estimating the following: activities of antioxidant enzymes, such as glutathione peroxidase and aging-related enzyme, particularly monoamine oxidase; contents of lipid peroxidation methane dicarboxylic aldehyde, advanced glycation end products, and 8-hydroxy-2'-deoxyguanosine (a DNA damage product); and levels of nuclear factor-erythroid 2-related factor 2. OFE and acteoside also inhibited d-galactose-induced neurological aging by suppressing the increase in glial fibrillary acidic protein and neurotrophin-3. Considering the dose-dependent protective effects of OFE and acteoside, we concluded that OFE, rich in acteoside, was a good source of natural antiaging compounds.

Abstract
OBJECTIVE Phototherapy using blue light-emitting diodes (LED) is effective against neonatal jaundice. However, green light phototherapy also reduces unconjugated jaundice. We aimed to determine whether mixed blue and green light can relieve jaundice with minimal oxidative stress as effectively as either blue or green light alone in a rat model. METHODS Gunn rats were exposed to phototherapy with blue (420-520 nm), filtered blue (FB; 440-520 nm without<440-nm wavelengths, FB50 (half the irradiance of filtered blue), mixed (filtered 50% blue and 50% green), and green (490-590 nm) LED irradiation for 24h. The effects of phototherapy are expressed as ratios of serum total (TB) and unbound (UB) bilirubin before and after exposure to each LED. Urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by HPLC before and after exposure to each LED to determine photo-oxidative stress. RESULTS Values < 1.00 indicate effective phototherapy. The ratios of TB and UB were decreased to 0.85, 0.89, 1.07, 0.90, and 1.04, and 0.85, 0.94, 0.93, 0.89, and 1.09 after exposure to blue, filtered blue, FB50, and filtered blue mixed with green LED, respectively. In contrast, urinary 8-OHdG increased to 2.03, 1.25, 0.96, 1.36, 1.31, and 1.23 after exposure to blue, filtered blue, FB50, mixed, green LED, and control, indicating side-effects (> 1.00), respectively. CONCLUSIONS Blue plus green phototherapy is as effective as blue phototherapy and it attenuates irradiation-induced oxidative stress. PRACTICE IMPLICATIONS Combined blue and green spectra might be effective against neonatal hyperbilirubinemia.

Abstract
A novel device combining electrochemical and colorimetric detection is developed for the rapid measurement of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a DNA oxidative damage biomarker. The device takes advantage of the speed and low cost of the conventional strip test as well as the high reliability and accuracy of the electrochemical assay. Competitive immunoreactions were performed on the lateral flow strip, and the captured 8-OHdG on the control line was determined by chronoamperometric measurement with carbon nanotube paper as the working electrode. At the same time, the color intensity of the test line was measured by a scanner and analyzed by the ImageJ software. The device was able to detect 8-OHdG concentrations in PBS as low as 2.07 ng mL(-1) by the colorimetric method and 3.11 ng mL(-1) by the electrochemical method. Furthermore, the device was successfully utilized to detect 8-OHdG in urine with a detection limit of 5.76 ng mL(-1) (colorimetric method) and 8.85 ng mL(-1) (electrochemical method), respectively. In conclusion, the integrated device with dual detection methods can provide a rapid, visual, quantitative and feasible detection method for 8-OHdG. The integration of these two methods holds two major advantages over tests based on a single method. Firstly, it can provide double confidence on the same assay. Secondly, by involving two methods that differ in principle, the integration could potentially avoid false results coming from one method. In addition, these methods do not require expensive equipment or trained personnel, making it suitable for use as a simple, economical, portable field kit for on-site monitoring of 8-OHdG in a variety of clinical settings.

Abstract
A highly sensitive, low-cost colorimetric aptasensor was developed for the determination of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in human urine. The method is based on a conformational switching of the 8-OHdG aptamer to form a G-quadruplex structure in the presence of 8-OHdG. The resulting G-quadruplex assembles into a peroxidase-like DNAzyme with hemin, which effectively catalyzes the oxidation of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS(2-)) by H2O2 to ABTS(+), resulting in an increase in the absorption signal at 416nm along with a color change of the solution. The response signals linearly correlated with the concentration of 8-OHdG, ranging from 466pM to 247nM with a detection limit of 141pM. The relative standard deviation and the recovery were 1.97-3.47% (n=11) and 98.8-100.2%, respectively. The proposed method avoids the label and derivatization steps in common methods and allows direct analysis of the samples by the naked eye without costly instruments, which is reliable, inexpensive, and sensitive.

Abstract
Cumulative evidence indicates that oxidative stress and inflammation frequently occurs in patients undergoing maintenance hemodialysis (HD) and as a result of overproduction of reactive oxygen species (ROS) and a decrease of antioxidant defenses such as selenium (Se). Previous studies in our laboratory showed that the supplementation of 1 unit of Brazil nut (the richest known food source of Se) a day during 3 months is effective to improve Se status and increase glutathione peroxidase (GPx) levels in HD patients. The aim of this study was to evaluate the effect of Brazil nut supplementation on oxidative stress and inflammation markers in HD patients. Forty HD patients from Rio de Janeiro, Brazil were studied. All patients received one nut per day for 3 months. The Se plasma levels and GPx, 8-isoprostane, 8-hydroxy-2-deoxyguanosine (8-OHdG), and cytokine (TNF-α and IL-6) levels and lipid profile were determined before and after 3 months of supplementation. The plasma Se and GPx activity increased, while cytokines, 8-OHdG, and 8-isoprostane plasma levels decreased significantly after 3 months supplementation. HDL-c levels increased and LDL-c levels decreased significantly. These data suggest that the consumption of only one Brazil nut per day during 3 months was effective to reduce the inflammation, oxidative stress markers, and the atherogenic risk, thereby increasing the antioxidant defenses in HD patients. Our results indicate that Brazil nut as Se source plays an important role as an anti-inflammatory and antioxidant agent in HD patients.

Abstract
The increased utilization of nanomaterials could affect human health and the environment due to increased exposure. Several mechanisms regarding the negative effects of nanomaterials have been proposed, one of the most discussed being oxidative stress. Many studies have shown that some metal oxide nanoparticles can enhance reactive oxygen species generation, inducing oxidative stress, DNA damage, and unregulated cell signaling, and eventually leading to changes in cell motility, apoptosis, and even carcinogenesis. 8-Hydroxy-2'-deoxyguanosine (8-OHdG) is one of the predominant forms of oxidative DNA damage, and has therefore been widely used as a biomarker for oxidative stress and carcinogenesis. Ther are two major objectives to this study. Firstly, the development of a novel lateral flow immunoassay (LFIA) is presented to measure the concentration of 8-OHdG in cells and thus reveal the nanotoxicity on the genomic level. The feasibility of this new method is validated by comparison with two other established methods: Alamar Blue assay and a recently developed electrical impedance sensing (EIS) system on the level of cell proliferation/viability. Secondly, the toxicological effects of three metallic nanoparticles (CuO, CdO, and TiO2 ) are investigated and compared using these three methods with completely different mechanisms. The results show that there is a high variation among different nanoparticles concerning their ability to cause toxic effects. CuO nanoparticles are the most potent regarding cytotoxicity and DNA damage. CdO shows a fallen cell viability as well as DNA damage, however, to a lesser extent than CuO nanoparticles. TiO2 particles only cause very limited cytotoxicity, and there is no obvious increase in 8-OHdG levels. In conclusion, LFIA as well as the EIS system are useful methods for quantitative or qualitative nanotoxicity assessments with high sensitivity, specificity, speed of performance, and simplicity.

Determination of low urinary 8-hydroxy-2`-deoxyguanosine excretion with capillary electrophoresis and molecularly imprinted monolith solid phase microextraction.

Abstract
As a sensitive biomarker, the level of 8-hydroxy-2`-deoxyguanosine (8-OHdG) indicates the extent of DNA oxidative damage of subject. However its determination in human urine is confounded by trace content and a complex matrix. In this study, a new approach of solid phase microextraction (SPME) coupled to capillary electrophoresis and electrochemical detection was developed with molecularly imprinted monolithic column as extraction sorbent. The tailor made monolith exhibited high extraction efficiency with the enrichment factor 73 for 8-OHdG owing to its special porous structure and inherent selectivity. Under optimal conditions, appreciable sensitivity had been achieved with a limit of detection of 2.61 nmol/L (signal/noise=3) and a limit of quantification of 8.63 nmol/L (signal/noise=10), respectively. As an alternative of precise 8-OHdG determination, wide range linearity had been achieved with 0.01-1.50 μmol/L and RSDs with 3.70% for migration time and 4.80% for peak current (10-1000 nmol/L). 106 samples with relative low extents of DNA oxidative damage were collected and analyzed which including coke plant workers, traffic policemen, taxi drivers and healthy students. Elevated urinary 8-OHdG excretions of subjects may correlate to working condition, occupational exposure, or lifestyle.

Abstract
A sensitive and low-cost analytical method has been developed to determine 8-hydroxy-2'-deoxyguanosine (8-OHdG) and 8-nitroguanine (8-NO(2)Gua) based on capillary electrophoresis with amperometric detection (CE-AD) after solid phase extraction (SPE). Under optimized condition, these two markers were well separated from other components coexisting in urine, exhibiting a linear calibration over the concentration range of 0.1-50.0 μg/mL with the detection limits ranging from 0.02 to 0.06 μg/mL. The relative standard deviations (RSDs) were in the range of 0.1-2.1% for peak area, 0.1-1.5% for migration time, respectively. The average recovery and RSD were within the range of 100.0-108.0% and 0.1-1.7%, respectively. It was found that the urinary contents of 8-OHdG and 8-NO(2)Gua in cancer patients were significantly higher than those in healthy ones.

Abstract
Guanosine derivatives are important for diagnosis of oxidative DNA damage including 8-hydroxy-2'-deoxyguanosine (8-OHdG) as one of the most abundant products of DNA oxidation. This compound is commonly determined in urine, which makes 8-OHdG a good non-invasive marker of oxidation stress. In this study, we optimized and tested the isolation of 8-OHdG from biological matrix by using paramagnetic particles with an antibody-modified surface. 8-OHdG was determined using 1-naphthol generated by alkaline phosphatase conjugated with the secondary antibody. 1-Naphthol was determined by stopped flow injection analysis (SFIA) with electrochemical detector using a glassy carbon working electrode and by stationary electrochemical detection using linear sweep voltammetry. A special modular electrochemical SFIA system which needs only 10 μL of sample including working buffer for one analysis was completely designed and successfully verified. The recoveries in different matrices and analyte concentration were estimated. Detection limit (3 S/N) was estimated as 5 pg/mL of 8-OHdG. This method promises to be very easily modified to microfluidic systems as "lab on valve". The optimized method had sufficient selectivity and thus could be used for determination of 8-OHDG in human urine and therefore for estimation of oxidative DNA damage as a result of oxidation stress in prostate cancer patients.

Rapid and simple one-step membrane extraction for the determination of 8-hydroxy-2'-deoxyguanosine in human plasma by a combination of on-line solid phase extraction and LC-MS/MS. J Chromatogr B Analyt Technol Biomed Life Sci 2011; 879:3538-43. [PMID: 21982910 DOI: 10.1016/j.jchromb.2011.09.038] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2011] [Revised: 09/14/2011] [Accepted: 09/16/2011] [Indexed: 01/10/2023]
Abstract
A quantitative analytical method using automated on-line solid phase extraction (SPE) and liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) for the determination of 8-OHdG (8-hydroxy-2'-deoxyguanosine) in human plasma was developed and validated. A one-step membrane extraction method for the plasma sample preparation and a C18 SPE column with simple extraction and purification were used for the on-line extraction. A C18 column was employed for LC separation and ESI-MS/MS was utilized for detection. (15)N(5)-8-OHdG ((15)N(5)-8-hydroxy-2'-deoxyguanosine) was used as an internal standard for quantitative determination. The extraction, clean-up and analysis procedures were controlled by a fully automated six-port switch valve as one strategy to reduce the matrix effect and simultaneously improve detection sensitivity. Identification and quantification were based on the following transitions: m/z 284→168 for 8-OHdG and m/z 289→173 for (15)N(5)-8-OHdG. Satisfactory recovery was obtained, and the recovery ranged from 95.1 to 106.1% at trace levels in human plasma and urine, with a CV lower than 5.4%. Values for intraday and interday precision were between 2.3 and 6.8% for plasma and between 2.7 and 4.5% for urine, respectively. Values for the method accuracy of intraday and interday assays ranged from 93.0 and 100.5% for plasma and 110.2 and 119.4% for urine, respectively. The limits of detection (LOD) and LOQ were 0.008 ng/mL and 0.02 ng/mL, respectively.The applicability of this newly developed method was demonstrated by analysis of human plasma samples for an evaluation of the future risk of oxidative stress status in human exposure to nanoparticles and other diseases.
