AB  - Fast, reliable, and inexpensive DNA sequencing is an important pursuit in healthcare, especially in personalized medicine with possible deep societal impacts. Despite significant progress in various nanopore-based sequencing configurations, challenges that remain in resolution and chromosome-size-long readout call for new approaches. Here we found strong rectification in the transversal current during single-stranded DNA translocation through a nanopore with side-embedded N-terminated carbon nanotube electrodes. Employing density functional theory and nonequilibrium Green’s function formalisms, we show that the rectifying ratio (response to square pulses of alternating bias) bears high nucleobase specificity. Rectification arises because of bias-dependent resistance asymmetry on the deoxyribonucleotide−electrode interfaces. The asymmetry induces molecular charging and highest occupied molecular orbital pinning to the electrochemical potential of one of the electrodes, assisted by an in-gap electric-field effect caused by dipoles at the terminated electrode ends. We propose the rectifying ratio, due to its order-of-magnitude-difference nucleobase selectivity and robustness to electrode-molecule orientation, as a promising readout quantifier for single-base resolution and chromosome-size-long single-read DNA sequencing. The proposed configurations are within experimental reach from the viewpoint of both nanofabrication and small current measurement.

AB  - Urban airborne particles contain a wide spectrum of components, known to have harmful effects on human health. This study reports a detailed investigation of fine particulate matter (PM2.5), chemical content and oxidative potential derived from two different urban environments. During summer and winter, 20-day campaigns were conducted at Belgrade city center (urban-background site – UB) and Bor (urban-industrial site – UI). Using various analytical techniques, carbonaceous compounds, water-soluble inorganic ions, major and trace elements were determined, while the oxidative potential of PM2.5 was estimated by dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay (OPDCFH values). The mean PM2.5 concentrations in both urban environments were above the recommended daily value, and the dominant PM2.5 mass contributor was organic matter (29–55%). The OC/EC ratio was significantly higher at UB site during winter, which was an indication of a considerable contribution of secondary organic carbon to the overall organic carbon (OC). Water-soluble organic carbon (WSOC) was also higher at UB than at UI site, and it probably came from the same sources as OC. In general, the different partition of secondary organic aerosol (SOA) in warm and cold periods affected the number of organic components. Sulfates and nitrates were the most abundant ions at both sites and they counted approximately 40% (summer) and 50% (winter) of total ions. Further, the concentrations of the most elements, particularly some potentially carcinogenic elements such as As, Cd and Pb were significantly higher at UI, due to the emissions from the copper smelter complex in the vicinity. The mean OPDCFH values were similar during the summer at both sampling sites, whereas a statistically significant difference between sites was noticed in favor of UB environment in winter.

AB  - Leptin (LEP) may contribute to the pathogenesis of multiple sclerosis (MS) by its immunomodulatory, proinflammatory and prooxidant effects. Therefore, plasma LEP levels and mRNA expression of five genes related to the LEP signaling pathway (LEP, LEP receptor (LEPR), peroxisome proliferator-activated receptor-gamma coactivator 1-alpha (PGC1A), superoxide dismutase 2, tumor necrosis factor-alpha) were investigated in relapsing-remitting MS. In patients (N = 64), compared to healthy subjects (N = 62), relative LEP mRNA levels were significantly increased (p = 0,01), while LEPR and PGC1A mRNA levels were decreased (p = 0,001 and p = 0,04, respectively). Significant positive correlation was observed between LEPR mRNA levels and clinical parameters of MS progression (EDSS, MSSS). © 2019

AB  - Objective: We explored the physiological background of the non-linear operating mode of cardiorespiratory oscillators as the fundamental question of cardiorespiratory homeodynamics and as a prerequisite for the understanding of neurocardiovascular diseases. We investigated 20 healthy human subjects for changes using electrocardiac RR interval (RRI) and respiratory signal (Resp) Detrended Fluctuation Analysis (DFA, α1RRI, α2RRI, α1Resp, α2Resp), Multiple Scaling Entropy (MSERRI1−4, MSERRI5−10, MSEResp1−4, MSEResp5−10), spectral coherence (CohRRI−Resp), cross DFA (ρ1 and ρ2) and cross MSE (XMSE1−4 and XMSE5−10) indices in four physiological conditions: supine with spontaneous breathing, standing with spontaneous breathing, supine with 0.1 Hz breathing and standing with 0.1 Hz breathing. Main results: Standing is primarily characterized by the change of RRI parameters, insensitivity to change with respiratory parameters, decrease of CohRRI−Resp and insensitivity to change of in ρ1, ρ2, XMSE1−4, and XMSE5−10. Slow breathing in supine position was characterized by the change of the linear and non-linear parameters of both signals, reflecting the dominant vagal RRI modulation and the impact of slow 0.1 Hz breathing on Resp parameters. CohRRI−Resp did not change with respect to supine position, while ρ1 increased. Slow breathing in standing reflected the qualitatively specific state of autonomic regulation with striking impact on both cardiac and respiratory parameters, with specific patterns of cardiorespiratory coupling. Significance: Our results show that cardiac and respiratory short term and long term complexity parameters have different, state dependent patterns. Sympathovagal non-linear interactions are dependent on the pattern of their activation, having different scaling properties when individually activated with respect to the state of their joint activation. All investigated states induced a change of α1 vs. α2 relationship, which can be accurately expressed by the proposed measure—inter-fractal angle θ. Short scale (α1 vs. MSE1−4) and long scale (α2 vs. MSE5−10) complexity measures had reciprocal interrelation in standing with 0.1 Hz breathing, with specific cardiorespiratory coupling pattern (ρ1 vs. XMSE1−4). These results support the hypothesis of hierarchical organization of cardiorespiratory complexity mechanisms and their recruitment in ascendant manner with respect to the increase of behavioral challenge complexity. Specific and comprehensive cardiorespiratory regulation in standing with 0.1 Hz breathing suggests this state as the potentially most beneficial maneuver for cardiorespiratory conditioning. © Copyright © 2020 Matić, Platiša, Kalauzi and Bojić.

AB  - Background: Carotid plaque is a hallmark of advanced carotid atherosclerosis and there is evidence of phosphatase and actin regulator 1 (PHACTR1) involvement in the processes that lead to atherosclerosis. PHACTR1 intronic variants have been associated with coronary artery disease and carotid dissection. Up to date the PHACTR1 haplotypes were not investigated in association with carotid plaque presence (CPP). So, the aims of this study were to investigate possible association of PHACTR1 haplotypes inferred from the intronic variants rs9349379, rs2026458 and rs2876300 with CPP in patients with advanced carotid atherosclerosis and to analyze their possible effect on PHACTR1 relative mRNA expression in carotid plaque tissue specimens. Methods: The study group consisted of 501 patients with evidence of carotid plaque presence admitted for carotid endarterectomy and 310 healthy controls. PHACTR1 rs9349379, rs2026458, rs2876300 and relative mRNA expression were detected by TaqMan® technology. Results: We have found significant and independent association of haplotype ACA with the CPP, compared to the referent haplotype GTA (adjusted OR = 1.54 95% CI = 1.07–2.21, p = 0.02). The OR was adjusted for gender, age, BMI, hypertension and total cholesterol. The relative expression of PHACTR1 mRNA in carotid plaque tissue proved to be significantly higher in carriers of the ACG haplotype compared to the referent haplotype GTA (p = 0.03). Conclusion: Our results suggest that PHACTR1 haplotypes inferred from the variants rs9349379, rs2026458 and rs2876300 affect PHACTR1 mRNA and bear the risk for CPP in patients with advanced carotid atherosclerosis. Further replication and validation studies are inevitable. © 2019 Elsevier B.V.

Further replication and validation studies are inevitable. © 2019 Elsevier B.V.",

AB  - Background: Chromosomal region 9p21.3 is most robustly associated with coronary artery disease (CAD) in western European populations. However, heterogeneity in CAD phenotypes leads to uncertainty whether 9p21.3 is associated with stable and/or acute clinical presentations of CAD. 9p21.3 is rich in regulatory elements, but the underlying mechanisms of its actions in CAD remain unclear. We investigate the association of 9p21.3 two haplotype blocks lead variants (rs10757278 and rs518394) with first-ever non-fatal myocardial infarction (MI) in CAD patients and their association with CDKN2B mRNA expression in peripheral blood mononuclear cells 6 months after the event. Methods: We included CAD patients with sustained first MI (n = 523) and controls (n = 583). Gene expression was assessed in 72 patients 6 months after MI and 43 healthy controls. TaqMan® technology was used for the gene expression and genotyping analysis. Results: CDKN2B mRNA was significantly lower in MI patients compared with the controls (p = 0.002) and in patients carrying the rs10757278 G risk allele versus AA homozygotes (p = 0.012) 6 months after the event. While we confirmed the association of rs10757278 with CDKN2B expression in MI patients, we failed to find an association between the investigated variants and MI or disease burden. Conclusions: We suggest a dysregulation of gene expression in the 9p21.3 region six months after acute MI, which is affected by a genetic variant in patients. The rs10757278 rare allele is one factor that might lead to prolonged risk for proatherogenic complications. © 2019 The Canadian Society of Clinical Chemists

Two most singnifficant clinical manifestations are stroke and myocardial infarction (MI), which development is affected by the median and hereditary factors (genetic predisposition). In this study, association of four genetic variants from chromosome region 9p21 have been investigated (rs10757278 and rs518394 in the ANRIL gene, and rs36212560 and rs2275888 in the HACD4 gene) with the risk for development of MI, the carotid plaque (CP) and its clinical complications (ultrasonographicaly deffined plaque type, symphtomatic disease, presence of carotid plaque ulceration). The transcription of genes CDKN2B and HACD4 at the mRNA level was examined in the CP tissue and peripheral blood mononuclear cells (PBMC) of patients who sustained first MI, six months after the infarction. Level of mRNA was examined in relation to genotypes and CP type.Signifficant association was determined for rs10757278 with the risk for CP development among females. It was determined that haplotype of gene variants rs36212560 and rs2275888 is significantly associated with the risk for CP and MI development.

AB  - The current compliance networks of automatic air-quality monitoring stations in large urban environments are not sufficient to provide spatial and temporal measurement resolution for realistic assessment of personal exposure to pollutants. Small low-cost sensor platforms with greater mobility and expected lower maintenance costs, are increasingly being used as a supplement to compliance monitoring stations. However, low-cost sensor platforms usually provide data with uncertain precision. To improve the precision, these sensor platforms require in-field calibration. Our paper aims to demonstrate that data from each individual sensor system can be corrected using that sensor system's own data to achieve much improved data quality compared to a reference. However, in this procedure, there are practical difficulties such as individual sensor outputs from the multi-sensor system not being sufficiently available due to malfunctions for instance. We explore how this can be dealt with. In our opinion, this is a novel approach, of practical importance both to users and manufacturers. We present a detailed comparative analysis of Linear Regression (univariate), Multivariate Linear Regression and Artificial Neural Networks used with a specific aim of calibrating field-deployed low-cost CO and O3 sensors. For Artificial Neural Network models, the performance of three common training algorithms was compared (Levenberg-Marquardt, Resilient back-propagation and Conjugate Gradient Powell-Beale algorithm). Data for this study were obtained from two campaigns conducted with 25 multi-sensor AQMESH v.3.5 platforms used within the activities of the CITI-SENSE project. The platforms were co-located to reference gas monitors at the Automatic Monitoring Station Stari Grad, in Belgrade, Serbia. This paper demonstrates that Multivariate Linear Regression and Artificial Neural Network calibration models can improve the output signal. This improvement can be measured by changes in the median and interquartile ranges of statistical parameters used for model evaluation. Artificial Neural Networks showed the best results compared to Linear Regression and Multivariate Linear Regression models. The best predictors for CO, in addition to CO low-cost sensor data, were PM2.5 and NO2, while for O3, in addition to O3 low-cost sensor data, the most suitable input predictors were NO and aH. Based on residual error analysis, we have shown that for CO and O3, a certain range of concentrations exists in which calibrated values differ by less than 10% from the reference method results. In addition, it was noted that for all models, CO sensors consistently showed lower variability between platforms compared to O3 sensors. © 2019 Elsevier Ltd

AB  - To estimate the oxidative potential (OP) of particulate matter (PM), two commonly used cell-free, molecular probes were applied: dithiothreitol (DTT) and dichloro-dihydro-fluorescein diacetate (DCFH-DA), and their performance was compared with 9,10-bis (phenylethynyl) anthracene-nitroxide (BPEAnit). To the best of our knowledge, this is the first study in which the performance of the DTT and DCFH has been compared with the BPEAnit probe. The average concentrations of PM, organic carbon (OC) and elemental carbon (EC) for fine (PM2.5) and coarse (PM10) particles were determined. The results were 44.8 ± 13.7, 9.8 ± 5.1 and 9.3 ± 4.8 µg·m−3 for PM2.5 and 75.5 ± 25.1, 16.3 ± 8.7 and 11.8 ± 5.3 µg·m−3 for PM10, respectively, for PM, OC and EC. The water-soluble organic carbon (WSOC) fraction accounted for 42 ± 14% and 28 ± 9% of organic carbon in PM2.5 and PM10, respectively. The average volume normalized OP values for the three assays depended on both the sampling periods and the PM fractions. The OPBPEAnit had its peak at 2 p.m.; in the afternoon, it was three times higher compared to the morning and late afternoon values. The DCFH and BPEAnit results were correlated (r = 0.64), while there was no good agreement between the BPEAnit and the DTT (r = 0.14). The total organic content of PM does not necessarily represent oxidative capacity and it shows varying correlation with the OP. With respect to the two PM fractions studied, the OP was mostly associated with smaller particles.

AB  - Abdominal Aortic Aneurysm (AAA) is a degenerative disease of the aortic wall with potentially fatal complications. Open Repair (OR) was considered the gold standard, until the emergence of Endovascular Aneurysm Repair (EVAR), which is less invasive and equally (if not more) effective. As the popularity of endovascular procedures grows, related complications become more evident, with kidney damage being one of them. Although Acute Kidney Injury (AKI) following EVAR is relatively common, its true incidence is still uncertain. Also, there is insufficient data concerning long-term renal outcomes after EVAR, especially with repeated contrast agent exposure. Despite the lack of firm evidence on the effectiveness of individual strategies, it is evident that prevention of AKI following EVAR requires a multifactorial approach. This review focuses on recent findings based on human studies regarding the current evidence of renal impairment after EVAR, its quantification and strategies for its prevention. © 2019 Bentham Science Publishers.

AB  - Chronic venous disease (CVeD) is a highly prevalent condition in the general population, and it has a significant impact on quality of life. While it is usually manifested by obvious signs, such as varicose veins and venous ulcers, other symptoms of the disease are less specific. Among the other symptoms, which include heaviness, swelling, muscle cramps and restless legs, pain is the symptom that most frequently compels CVeD patients to seek medical aid. However, there is a substantial discrepancy between pain severity and clinically detectable signs of CVeD, questioned by several opposing studies. Further evaluation is needed to clarify this subject, and to analyse whether pain development predicts objective CVeD progression. General management of CVeD starts with advising lifestyle changes, such as lowering body mass index and treating comorbidities. However, the mainstay of treatment is compression therapy, with the additional use of pharmacological substances. Venoactive drugs proved to be the drugs of choice for symptom alleviation and slowing the progression of CVeD, with micronized purified flavonoid fraction being the most effective one. Interventional therapy is reserved for advanced stages of the disease.

The electronic structure is modeled by means of the sp3d5s∗ tight-binding method within the nearest-neighbor approximation. Both bulklike and edge states appear in the energy spectrum. The bulklike states in quantum rings exhibit Aharonov-Bohm oscillations in magnetic field, whereas no such oscillations are found in quantum dots, which is ascribed to the different topology of the two systems. When magnetic field varies, all the edge states in square quantum dots appear as quasibands composed of almost fully flat levels, whereas some edge states in quantum rings are found to oscillate with magnetic field. However, the edge states in hexagonal quantum dots are localized like in rings. The absorption spectra of all the structures consist of numerous absorption lines, which substantially overlap even for small line broadening. The absorption lines in the infrared are found to originate from transitions between edge states.

AB  - The paper deals with the analysis of the annual indoor radon concentrations variations due to different geological parameters of Sjenica community, Western Serbia. The measured 222Rn concentrations were ranging from 10 to 1130 Bq/m3. In 14% of the buildings, the radon action level of 300 Bq/m3 is exceeded, indicating that Sjenica community could be characterized as a radon priority area. Each of 35 measuring location was georeferenced and corresponding lithostratigraphic units and geological period was assigned.

abstract = "The paper deals with the analysis of the annual indoor radon concentrations variations due to different geological parameters of Sjenica community, Western Serbia. The measured 222Rn concentrations were ranging from 10 to 1130 Bq/m3. In 14% of the buildings, the radon action level of 300 Bq/m3 is exceeded, indicating that Sjenica community could be characterized as a radon priority area. Each of 35 measuring location was georeferenced and corresponding lithostratigraphic units and geological period was assigned. Data were analyzed using the multiple linear regression (MLR) method and two predictive models were developed. The MLR model generated by the geological periods explained 17% of the radon variability while, the better one, was the lithostratigraphic MLR model, which explained 52% of the radon variability.

AB  - The subject of this study is the radon concentrations variations, measured with a nuclear track detectors in a total of 58 premises in all 29 primary schools of 4 municipalities in the Eastern part of the Republic of Macedonia. Despite a relatively small territory, the variability of radon concentrations proved to be significant. The geometric means (geometric standard deviations) of radon concentrations in the examined municipalities were in the range from GM = 71 Bq/m 3 (GSD = 2.08) to GM = 162 Bq/m 3 (GSD = 2.69), while for the entire region it was: GM = 96 Bq/m 3 (GSD = 2.47). The influence of the geographical and geological features of the school site as well as the building characteristics on the radon variations were investigated. The analysis showed that type of municipality, building materials, basement and geology have significant effects and respectively describe 6%, 16%, 22%, 39% of the radon total variability.

AB  - Urine, hair and nail samples were collected from a population of both sex aged from 40 to 87 years in Niška Banja (227 km south of Belgrade, Serbia) with a high level of natural radioactivity (HLNRA). To assess and monitor the public exposure, urine samples for each subject (24 h period) were collected and concentration of uranium (U) was analysed using alpha-particle spectrometry. Human hair and nails considered as bio-indicators of the public exposure to radionuclides over a long period of months or even years and concentration of U was determined using inductively coupled plasma-mass spectrometry. The mean concentrations of U in urine, hair and nail were 123 ng/L, 17 ng/g and 8 ng/g, respectively. There was a large variation and may be due to geological origin.

AB  - The 9p21.3 region is rich in regulatory elements and the variants in this region had been robustly associated with carotid plaque (CP) and coronary artery disease (CAD). Recently, the HACD4 was detected as one of the six 9p21.3 differentially expressed genes associated with accelerated atherosclerosis and greater mean lesion area in the Athsq1 congenic mice. We aimed to investigate association of two potentially regulatory HACD4 variants (rs36212560 I/D, rs2275888 T/C) and their haplotypes with CP occurrence and the level of HACD4 and FOCAD mRNA in human CP tissue. Association study was replicated in CAD patients who suffered the first myocardial infarction. Study included 477 CP patients, 303 healthy controls and replication sample of 224 CAD males from the population of Serbia. Genotypes were determined by polymerase chain reaction (PCR) and real-time PCR using TaqMan (R) technology. The gene expression was detected with TaqMan (R) technology. We have found significant and independent association of DT haplotype with CP presence in men (adjusted OR = 1.64 CI = 1.12-2.42, p = 0.011). The result was replicated in CAD males (adjusted OR = 1.84 CI = 1.21-2.80, p = 0.004). We have found significant effect of the HACD4 rs2275888 on FOCAD mRNA level in human CP tissue. Correction for multiple testing was performed. Independent association of HACD4 haplotypes with atherosclerotic phenotypes connotes a further validation and replication in larger cohorts as well as functional studies to enlighten the potential mechanism of its action in pathophysiology of atherosclerosis.

AB  - Aims: (1) to identify the most dysregulated genes in ureter tissue affected by congenital anomalies of the kidney and urinary tract (CAKUT) and to extract the biological meaning of these markers; (2) to describe the key molecular networks in CAKUT and to provide expression validation of the genes selected from these networks. Main methods: Transcriptome data was obtained from ureter samples of CAKUT patients and controls by Illumina iScan microarray. Identification of differentially expressed genes was coupled with subsequent bioinformatics analyses. Expression of candidate genes was validated by qRT-PCR. Key findings: Analysis of the transcriptome led to the identification of 78 commonly dysregulated genes in CAKUT tissue compared to controls. Integrative bioinformatic analyses of differentially expressed genes identified 7 major networks. The targets for qRT-PCR validation were selected as members of the major molecular networks in CAKUT, which had both, the significant high fold change and biological relevance for CAKUT. By qRT-PCR the substantial increase of LCN2, PROM1, SOSTDC1, and decrease of INA, RASD1 and TAC3 mRNA levels was confirmed. Significance: Since CAKUT is a leading cause of end-stage renal disease in children, the search for molecular targets for postnatal therapy is of particular interest. Data described in this study represents the gene expression profile and significant molecular networks specific to human ureter affected by CAKUT. The discovery of impaired molecular factors and processes is the step towards the uncovering of the key mechanisms that reflect CAKUT postnatally and could lead to the affected tissue deterioration and end organ damage. © 2018 Elsevier Inc.

AB  - Post-infarct left ventricular remodeling (LVR) process increases the risk of heart failure (HF). Circulating galectin-3 has been associated with fibrosis, inflammation and cardiac dysfunction during the remodeling process after myocardial infarction (MI). The aims of this prospective case study were to investigate the association of potentially functional variants in the vicinity of LGALS-3 locus, rs2274273 and rs17128183 with maladaptive LVR and whether these variants could affect LGALS-3 mRNA expression in peripheral blood mononuclear cells of patients 6 months after the first MI. This study encompassed 167 patients with acute MI that were followed up for 6 months. Evidence of LVR was obtained by repeated 2D Doppler echocardiography. Rs2274273, rs17128183 and LGALS-3 mRNA expression were detected by TaqMan® technology. Rs2274273 and rs17128183 rare allele bearing genotypes, according to the dominant model (CT+TT vs. CC and AG+GG vs. AA, respectively), were significantly and independently associated with maladaptive LVR (adjusted OR = 3.02, P = 0.016; adjusted OR = 3.14, P = 0.019, respectively) and higher LGALS-3 mRNA expression (fold induction 1.203, P = 0.03 and 1.214, P = 0.03, respectively). Our exploratory results suggest that rs2274273 and rs17128183 variants affect LGALS-3 mRNA and bear the risk for maladaptive LVR post-MI remodeling. Further replication and validation in a larger group of patients is inevitable. © 2018, Springer Nature B.V.

AB  - In this study, we assessed whether the disturbed regulation of sodium/potassium-adenosine-triphosphatase (Na+/K+-ATPase) occurs as a consequence of obesity-induced IR in sex-specific manner. We also assessed whether alterations of IRS/PI3K/Akt, ERK1/2, AMPK alpha, and RhoA/ROCK signaling cascades have an important role in this pathology. Female and male Wistar rats (150-200 g, 8 weeks old) were fed a standard laboratory diet or a high-fat (HF) diet (42% fat) for 10 weeks. The activity of hepatic Na+/K+-ATPase and Rho, and the association of IRS-1/p85 were assessed in liver. Furthermore, the protein level of alpha(1) Na+/K+-ATPase in plasma membrane fractions, and protein levels of IRS-1, PI3K-p85, -p110, RhoA, ROCK1, ROCK2, ERK1/2, AMPK alpha, ER alpha, and ER beta in liver lysates were assessed. The expression of hepatic alpha(1) Na+/K+-ATPase mRNA was also analyzed by qRT-PCR. The results show that HF-fed female rats exhibited an increase in hepatic ERK1/2 (p < 0.05) and AMPK alpha (p < 0.05) phosphorylation levels, unchanged level of Na+/K+-ATPase alpha(1) mRNA, decreased level of Na+/K+-ATPase activity (p < 0.05), and decreased alpha(1) Na+/K+-ATPase protein expression (p < 0.01). In liver of HF-fed male rats, results show decreased levels of Na+/K+-ATPase activity (p < 0.01), both protein and mRNA of alpha(1) subunit (p < 0.05), but significant increase in Rho activity (p < 0.05). Our results indicate significant sex differences in alpha(1) Na+/K+-ATPase mRNA expression and activation of ERK1/2, AMPK alpha, and Rho in the liver. Exploring the sex-specific factors and pathways that promote obesity-related diseases may lead to a better understanding of pathogenesis and discovering new therapeutic targets.

AB  - A number of measures, stemming from nonlinear dynamics, exist to estimate complexity of biomedical objects. In most cases they are appropriate, but sometimes unconventional measures, more suited for specific objects, are needed to perform the task. In our present work, we propose three new complexity measures to quantify complexity of topographic closed loops of alpha carrier frequency phase potentials (CFPP) of healthy humans in wake and drowsy states. EEG of ten adult individuals was recorded in both states, using a 14-channel montage. For each subject and each state, a topographic loop (circular directed graph) was constructed according to CFPP values. Circular complexity measure was obtained by summing angles which directed graph edges (arrows) form with the topographic center. Longitudinal complexity was defined as the sum of all arrow lengths, while intersecting complexity was introduced by counting the number of intersections of graph edges. Wilcoxon's signed-ranks test was used on the sets of these three measures, as well as on fractal dimension values of some loop properties, to test differences between loops obtained in wake vs. drowsy. While fractal dimension values were not significantly different, longitudinal and intersecting complexities, as well as anticlockwise circularity, were significantly increased in drowsy.

AB  - Introduction: Recently, rs2275888 eQTL in PTPLAD2 gene has been associated with expression of several loci, during inflammatory stimulation in monocytes. Myocardial infarction (MI) triggers an intense inflammatory response that is essential for cardiac repair. We aimed to perform data scouting in appropriate rs2275888 genotype model to identify differentially expressed genes (DEGs), their biological meaning, and key miRs potentially associated with rs2275888 eQTL in peripheral blood mononuclear leucocytes (PBML) of MI patients 6 months after first MI. Methods: Transcriptome data was obtained from PBMLs of 21 patients, who suffered ischemic MI, by employing Illumina iScan microarray technology. Genotyping for rs2275888 was conducted with real-time PCR, using TaqMan® assay. Preprocessing and identification of DEGs was done using limma package of R/Bioconductor software. The online tool DAVID v6.8 was employed for functional enrichment analysis. Most important miRs were selected using NetworkAnalyst web tool, based on the degree centrality value. Results: Transcriptome analysis in recessive model TT+TC (n=19) vs. CC (n=2) identified 68 DEGs. Top significant biological processes involving DEGs cover vascular physiology, cell growth and signaling. Pathway analysis associated DEGs with adherens junction, Rap1 and Ras signaling. Network analysis identified hsa-miR335-5p, -26b-5p, -93-5p, -16-5p, -124-3p, -20b-5p, -17-5p and -218-5p as miRs with top centrality degree in our DEGs list. Conclusion: Seven of eight detected miRs have already been described in MI pathology or suggested as potential biomarkers for MI. Our result suggest the importance of integration of eQTLs, biological processes and pathway analysis coupled with miR activity for further research in MI pathology.
