Authors: Rajput Deepak , Costa Lino , Lansford Kathleen , Murray George M. , Hofmeister WilliamH.
Published: April 2019

This paper reports the deposition of transition metal coatings on graphite by laser melting a pre-placed layer of powder particles using a continuous wave (CW) laser. Titanium, zirconium, and niobium coatings were successfully deposited on semiconductor grade graphite plates using the laser induced surface improvement (LISI) approach. The coatings produced were characterized using scanning electron microscope, energy dispersive spectrometry, X-ray diffraction, microhardness testing, and secondary ion mass spectrometry. Results show the formation of crack-free and dense transition metal coatings and the presence of carbide phases at the coating-graphite interface.

The sol-gel synthesis and precipitation from dimethyl sulfoxide (DMSO)-water mixture were used to obtain LiFePO4. Sucrose (sucr), citric acid (CA), phthalic acid (phth), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), polyvinylidene fluoride (PVDF), polyethylene glycol (PEG), polyacrylic acid (PAA) were investigated as carbon precursors. Increasing of the annealing temperature from 600 °» to 800 °» leads to a certain perfection of graphite structure with simultaneous particle size growth. Higher capacities were observed for the materials synthesized at 600 °». The best results for the sol-gel synthesis were obtained when PVDF was used as a source of carbon coating due to the partial fluorination of LiFePO4 (discharge capacity of LiFePO4/ C-PVDF was ~160 and 70 mAh g-1 at 20 mA g-1 and 800 mA g-1 currents, respectively). For nanocrystalline LiFePO4 obtained by precipitation from DMSO-water mixture the best results were obtained when PEG was used as carbon source (discharge capacity LiFePO4/C-PEG was 158 and 77 mAh g-1 at 20 mA g-1 and 800 mA g-1, respectively).

Authors: Selyutina N.S. , Petrov Yu.V.
Published: April 2019

In the paper, a new phenomenological interpretation of some of the principal temporal effects of high-rate plastic deformation of metals from a united viewpoint is represented. A comparative analysis of some of the well-known dynamic plastic deformation models is given. Influence of strain rate on the stress-strain relation in a wide range of strain rates for different types of aluminum alloys and steels is described by the relaxation model of plasticity, by original and improved empirical Johnson-Cook models, and by the phenomenological Rusinek-Klepaczko model. It is shown that the structural-time model (“the relaxation model of plasticity”) is capable to effectively predict a wide spectrum of materials responses to fast and slow dynamic loading.

Published: April 2019

High-resolution ultrasonic mechanical spectroscopy technique has been used to study the nature and dynamics of lattice defects and magnetic domain walls in the helical-type antiferromagnetic phase during thermal cycling of polycrystalline Dy samples between 80 and 210K. Effects of the lowest temperature of thermal cycles, applied magnetic field and cooling/ heating rate on the ultrasonic absorption and Young´s modulus have been investigated. A strong influence of cooling/heating rate on the ultrasonic absorption is found over the temperature range between the Néel temperature, ca. 178K, and approximately 145K, confirming the existence of a new category of magnetomechanical damping - transitory ultrasonic absorption related to translational motion of domain walls. A strong increase of the ultrasonic absorption below approximately 140K is attributed to the formation of nuclei of ferromagnetic phase, presumably stabilized by such lattice defects as dislocations. The effect of applied magnetic field on ultrasonic absorption also emerges below 140K and is ascribed to the appearance of the net magnetization due to ferromagnetic nuclei. We argue that these nuclei are responsible for the controversial thermal hysteresis of elastic and anelastic properties, which is strongly promoted by decreasing the temperature of thermal cycles.

Published: April 2019

A new mechanism of nonradiative recombination of nonequilibrium carriers in semiconductor quantum wells is suggested and discussed. For a studied Auger recombination process the energy of localized electron-hole pair is transferred to barrier carriers due to Coulomb interaction. The analysis of the rate and the coefficient of this process is carried out. It is shown, that there exists two processes of thresholdless and quasithreshold types, and thresholdless one is dominant. The coefficient of studied process is a non-monotonous function of quantum well width having maximum in region of narrow quantum wells. Comparison of this process with CHCC process shows that these two processes of nonradiative recombination are competing in narrow quantum wells, but prevail at different quantum well widths.

Published: April 2019

Here we analyze the microstructure and phase composition of a Ti alloy with 0.16Pd and 0.14Fe (wt%) alloy exposed to warm equal channel angular pressing (ECAP) at 648 K. The analysis shows that after four ECAP passes, the material assumes a submicrocrystalline structure with an average grain size of 0.28 μm, as against its initial value 10 μm, and that the α phase dominates in the alloy both before and after ECAP. The initial alloy reveals a high content of Fe and Pd atoms near grain boundaries compared to central grain regions. Such near-boundary zones contain orthorhombic α′′ martensite in addition to the α phase, and β or α + β particles are found directly at the grain boundaries. These features of the phase composition are inherited after ECAP. The yield strength of the ECAP treated alloy is 500 MPa, being greater than the initial strength 350 MPa, and its margin of plasticity is rather high. The torsional strain up to fracture in the initial and in the ECAP treated alloy is 70% and 50%, respectively.

Alltägliche Praktiken zur Herstellung von Geschlechts-Körpern oder: Warum Unisex-Toiletten von Verfassungs wegen geboten sind
Authors: Lembke Ulrike
Published: April 2019

Geschlechtersegregierte Toiletten sind Räume der interaktiven, symbolischen und zugleich alltäglichen, durch Einschreibung in die Körper höchst wirkmächtigen Herstellung hierarchischer Geschlechterverhältnisse. Soziologisch interessant sind die Verdichtung ineinandergreifender individueller, kollektiver und struktureller Prozesse der Konstitution von Geschlecht, welche verschiedene Geschlechtertheorien exemplarisch verdeutlichen können, sowie die in diesem Kontext wenig erforschten alltäglichen vor-reflexiven Praktiken der Bestätigung von Geschlechts-Körpern. Auch im Sprechen über die behauptete Notwendigkeit geschlechtersegregierter Toiletten wird die bipolare Heteronorm bzw. Heteronormativität beständig abgesichert, wie die Auswertung einer entsprechenden Forumsdiskussion zeigt. Die teils aggressive Behauptung gängiger Geschlechterstereotype, Naturalisierungsstrategien, ent-politisierende Intimitätsargumente und die strategische Bezugnahme auf geschlechtsspezifische Gewalt zur Absicherung männlicher Privilegien belegen einmal mehr, dass es hier nicht nur um die Rechte einer vielzitierten Minderheit geht, sondern um gesellschaftlich-strukturell bedeutsame Normen. In einem diesen Erkenntnissen entsprechenden, mehrdimensionalen Modell von Geschlechtsdiskriminierung, welches die externe wie die interne Dimension berücksichtigt, erweist sich die Geschlechtersegregation von Toiletten als Verletzung des Verbots der Geschlechtsdiskriminierung aus Artikel 3 Absatz 3 Grundgesetz und des Gebots der Gleichberechtigung aus Artikel 3 Absatz 2 Grundgesetz, welche nicht gerechtfertigt werden kann.
Political and Governance Challenges to Achieving Global HIV Goals with Injecting Drug Users: The Case of Pakistan
Authors: Khalid Hina , Fox Ashley M.
Published: April 2019

Background: The Joint United Nations Programme on HIV/AIDS (UNAIDS) has recently set the ambitious "90-90-90 target" of having 90% of people living with HIV (PLHIV) know their status, receive antiretroviral therapy (ART), and achieve viral suppression by 2020. This ambitious new goal is occurring in a context of global "scale-down" following nearly a decade of heightened investment in HIV prevention and treatment efforts. Arguably international goals spur action, however, setting unrealistic goals that do not take weak health systems and variations in the nature of the epidemic across countries into consideration may set them up for failure in unproductive ways that lead to a decline in confidence in global governance institutions. This study explores how policy actors tasked with implementing HIV programs navigate the competing demands placed upon them by development targets and national politics, particularly in the current context of waning international investments towards HIV. Methods: To examine these questions, we interviewed 29 key informants comprising health experts in donor organizations and government employees in HIV programs in Pakistan, a country where HIV programs must compete with other issues for attention. Themes were identified inductively through an iterative process and findings were triangulated with various data sources and existing literature. Results: We found both political and governance challenges to achieving the target, particularly in the context of the global HIV scale-down. Political challenges included, low and heterogeneous political commitment for HIV and a conservative legal environment that contributed towards a ban on opiate substitution therapy, creating low treatment coverage. Governance challenges includedstrained state and non-governmental organization (NGO) relations creating a hostile service delivery environment, weak bureaucratic and civil society capacity contributing to poor regulation of the health infrastructure, and resource mismanagement on both the part of the government and NGOs. Conclusion: Our findings suggest that in a context of waning international attention to HIV, policy actors on the ground face a number of practical hurdles to achieving the ambitious targets set out by international agencies. Greater attention to the political and governance challenges of implementing HIV programs in low- and middle-income countries (LMICs) could help technical assistance agencies to develop more realistic implementation plans.

Published: April 2019

Addressing the determinants of non-communicable diseases (NCDs) is challenged by aggressive market promotion by tobacco, alcohol and unhealthy food industries in emerging countries with fast economic development; and interference by these industries in government policies aimed at containing consumption of unhealthy products. This editorial reviews market promotion and industry interference and classifies them into four groups of tactics: (a) interfering with the legislative process; (b) using front groups to act on their behalf; (c) questioning the evidence of tobacco harm and the effectiveness of harm-reduction interventions; and (d) appearing responsible in the eyes of the public, journalists and policy-makers. Despite active implementation of the Framework Convention on Tobacco Control (FCTC), the tobacco, alcohol and unhealthy food industries use similar tactics to aggressively interfere in policies, with the tobacco industry being the most aggressive. Policy interference by industries are effective in the context of poor governance, rampant corruption, conflict of interest among political and government actors, and regulatory capture in all levels of countries from low- to high-income. In addressing these interferences, government requires the practice of good governance, effective mechanisms to counteract conflict of interests among political and policy actors, and prevention of regulatory capture. The World Health Organization (WHO) Framework of Engagement with non-State Actors can be applied to the country context when engaging private entities in the prevention and control of NCDs.

Stastny, P, Lehnert, M, De Ste Croix, M, Petr, M, Svoboda, Z, Maixnerova, E, Varekova, R, Botek, M, Petrek, M, Lenka, K, and Cięszczyk, P. Effect of COL5A1, GDF5, and PPARA genes on a movement screen and neuromuscular performance in adolescent team sport athletes. J Strength Cond Res 33(8): 2057–2065, 2019—The risk of injury increases with adolescents' chronological age and may be related to limited muscle function neuromuscular, genetic, and biomechanical factors. The purpose of this study was to determine whether COL5A1, PPARA, and GDF5 genes are associated with muscle functions and stretch-shortening cycle performance in adolescent athletes. One hundred forty-six youth players (14.4 ± 0.2 years) from various team sports (basketball n = 54, soccer n = 50, handball n = 32) underwent a manual test for muscle function, maturity estimation, functional bend test (FBT), passive straight leg raise (SLR) test, leg stiffness test, test of reactive strength index (RSI), and gene sampling for COL5A1, PPARA, and GDF5. The χ2 test did not show any differences in allele or genotype frequency between participants before and after peak height velocity. Multivariate analysis of variance showed that COL5A1 rs12722 CT heterozygotes had worse score in FBT (p < 0.001), worse score in SLR (p = 0.003), and lower maturity offset (p = 0.029, only in females) than TT homozygotes. Male GDF5 rs143383 GG homozygotes showed better score in SLR than AA and AG genotypes (p = 0.003), and AA and AG genotypes in both sex had greater RSI than GG homozygotes (p = 0.016). The PPARA rs4253778 CC homozygotes had greater RSI than GG and GC genotypes (p = 0.004). The CT genotype in COL5A1 rs12722 is possible predictor of functional movement disruption in the posterior hip muscle chain, causing shortening in FBT and SLR, which includes hamstrings function. CT genotype in COL5A1 rs12722 should be involved in programs targeting hamstring and posterior hip muscle chain.

Delaney, JA, Wileman, TM, Perry, NJ, Thornton, HR, Moresi, MP, and Duthie, GM. The validity of a global navigation satellite system for quantifying small-area team-sport movements. J Strength Cond Res 33(6): 1463–1466, 2019—The recent development of global navigation satellite systems (GNSS) has improved the availability and signal strength of surrounding satellites compared with traditional global positioning systems, although their ability to quantify rapid changes in speed may still be limited. This study aimed to evaluate the validity of GNSS to quantify the mean speed (m·s−1) and acceleration (m·s−2) of movements typical to team sports. One participant completed 9 periods of 4 minutes of activity, separated by 2-minute rest periods, which involved walking, jogging, and running in a variety of directions and patterns, aimed to simulate a team-sport movement profile. Speed and acceleration were quantified from a 10-Hz GNSS unit and compared with a 10-camera, 3-dimensional motion capture system (VICON), from which the movement of both the participant's center of mass (COM) and the location of the GNSS unit (e.g., C7 vertebrae) were calculated. Practical estimates of speed were associated with small differences from both the criterion COM (effect size; ±90% confidence limits = 0.19–0.25; ± ∼0.21) and criterion C7 (0.14–0.22; ± ∼0.13). The corresponding estimates of acceleration derived from raw data were classified as small (0.16–0.22; ± ∼0.15) and small to moderate (0.25–0.35; ± ∼0.24) for the COM and C7, respectively. Software-exported acceleration values exhibited very large mean bias compared with both criterion measures (−3.81 to −3.77; ± ∼0.24). This study demonstrates that 10-Hz GNSS possess acceptable validity for assessing the average demands of movements typical of team-sports training and competition, although caution is recommended when using software-exported measures of acceleration.

Currier, BS, Harty, PS, Zabriskie, HA, Stecker, RA, Moon, JM, Jagim, AR, and Kerksick, CM. Fat-free mass index in a diverse sample of male collegiate athletes. J Strength Cond Res 33(6): 1474–1479, 2019—Fat-free mass index (FFMI) is a body composition metric that has been used to assess relative muscularity in athletes. Fat-free mass index is calculated by dividing FFM by height squared, although further height corrections through linear regression may be needed in taller individuals. This study reported height-adjusted FFMI (FFMIAdj) data in 209 male collegiate athletes from 10 sports (baseball, cross country, football, golf, ice hockey, weightlifting, rugby, swimming, track and field, and water polo) and the FFMIAdj natural upper limit for sports with sufficient sample size. The body composition of all subjects (mean ± SD; age: 20.7 ± 1.9 years, height: 182.9 ± 6.7 cm, body mass: 90.8 ± 16.8 kg, and percent body fat: 15.6 ± 5.3) was measured using dual-energy x-ray absorptiometry. Linear regression was used to adjust for height, and the FFMIAdj natural upper limit was determined by calculating the 97.5th percentile of all values. One-way analyses of variance with Games-Howell post hoc comparisons were used to determine between-sport differences. A paired-samples t-test revealed a significant difference (p < 0.001) between unadjusted and adjusted mean FFMI values. The overall mean FFMIAdj was 22.8 ± 2.8 kg·m−2. Significant between-sport differences (p < 0.001) in FFMIAdj were identified. Average FFMIAdj was highest in football athletes (24.28 ± 2.39 kg·m−2) and lowest in water polo athletes (20.68 ± 3.56 kg·m−2). The FFMIAdj upper limit was calculated for all athletes (28.32 kg·m−2), rugby (29.1 kg·m−2), and baseball (25.5 kg·m−2). This study reported FFMIAdj values in a diverse cohort of male collegiate athletes, providing data for the first time in several sports. These values can be used to guide nutritional and exercise interventions, predict athletic performance, and provide coaches with standardized information regarding the potential for further FFM accretion in male athletes.
A random decision for testing of the homogeneity of normal means against the tree order alternative
Authors: MOMENİ Reza , ETMİNAN Javad , KHANJARİ SADEGH Mohamad
Published: April 2019

Consider the problem of testing the homogeneity of k + 1 normal means under the tree order restriction. In this paper, we propose new multiple comparisons procedures for testing of the tree order constraint. New test procedures with the corresponding simultaneous confidence intervals are motivated by some new estimation methods which are constructed based on a random decision and the Bayesian approach. Also, these procedures are developed for two-sided tree order alternatives. We compare the performance of the proposed methods with some existing test procedures, such as likelihood ratio test and some multiple comparisons tests for the tree order constraint. In some cases, the gains in power due to the proposed procedures can be substantial. The results for two sided alternative are similar to the one-sided hypotheses and two new procedures perform well for almost every configuration. We illustrate the efficiency of the proposed methods by analyzing of the two bioassay numerical examples.

Difficulties of diagnostics of acute myocardial infarction in elderly and senile patients and their influence on management in the acute period of disease
Authors: Tukish O. V. , Garganeeva A. A.
Published: April 2019

Aim. To study the features of disease progress and approaches to the diagnostics of acute myocardial infarction (MI) among elderly and senile patients and their influence on the management in the acute period of disease.

Materials and methods. The study was performed using the WHO program “Register of acute myocardial infarction” (Tomsk). The study included 410 patients (60 years and older), who had acute MI. The study group is represented by a comparable number of men (n=212) and women (n=198). The mean age of patients was 71 (66; 77) years (women are 5 years older than men (p<0,001)). Statistical processing was performed using the program Statistica V10.0.

Results. Most of the patients had history comorbid pathology. In one in five patients (17,8%), the disease had an atypical manifestations, which in 41% of cases was represented by the asymptomatic form. Atypical manifestation of MI lengthened the prehospital phase of medical care due to a longer time before the first medical contact (p=0,005), as well as a late help-seeking (120 [49; 311,5] minutes). In 28% of patients, the level of creatine kinase-MB remained normal, and the indicator of troponin I exceeded the maximum values only in half of the cases. One fifth of the patients underwent acute MI treatment in non-core hospitals, which resulted in a low frequency of intervention (38%) and increasing by 2 times the chance of death within 5 years. The level of hospital mortality from acute MI in elderly patients in noncore hospitals was 3 times higher than in specialized departments (p<0,001).

Conclusion. Difficulties in diagnostics of MI in patients of older age groups is caused by the prevalence of comorbid pathology, an atypical manifestations of the disease and low information content of biochemical markers of myocardial necrosis. It leads to an increase in time delays at the prehospital phase and frequent hospitalization of patients in non-core hospitals, making it impossible for them to receive timely, preferred therapy.

Aim.Defibrillation lead implantation technique optimization using cardiac scintigraphy in patients with coronary artery disease (CAD).

Material and methods.In this study 81 patients (male — 72, age 64,0±8,7 years with CAD and indications for the cardioverter-defibrillator (ICD) implantation were examined. Patients were divided into two groups. In 1-st group before ICD implantation, patients underwent cardiac 99mTc-methoxy-isobutyl-isonitrile scintigraphy for right ventricle wall perfusion disorders assessment. In this group defibrillating lead was implanted to the septal position, if the perfusion disorders were in the apical segments, and to the apical position, if perfusion disorders were in the septal segment. In 2-nd group lead was implanted using conventional approach. Defibrillating lead parameters (threshold, sense, impedance and shock impedance on 1-st, 7-th, 30-th and 180-th follow-up days) were compared.

Results.The 1-st group consisted of 45 (55,5%) patients (male — 41, age 62,2±8,8 years). In 28 (62,2%) cases in this group defibrillating lead was implanted to the apical and in 17 (37,8%) — to the septal position. The 2-nd group consisted of 36 (44,5%) patients (male — 31, age 66,3±8,2 years; p=0,03). In 20 (55,5%) cases in this group defibrillating lead was implanted to the septal and in 16 (44,5%) — to the apical position. There were significant differences between groups in terms of: threshold and sense at all follow-up days (p=0,0001) and impedance on 1-st (p=0,003), 30-th (p=0,0001) and 180-th day (p=0,002), respectively.

Conclusion.Assessment of right ventricular perfusion before ICD implantation can reduce threshold and raise sense, thereby prolong the ICD longevity and improve life-threatening ventricular tachyarrhythmia detection in the early and long-term period in patients with CAD.

Aim.To study associations of the estimated glomerular filtration rate (eGFR) with non-coronary atherosclerosis progression criteria and risk factors one year after coronary bypass surgery (CABG).

Material and methods.Of the 732 patients consecutively operated (586 men and 146 women, median age 59 years), 504 people visited the study center 1 year after CABG. At the preoperative and annual stages, all patients were assessed with the same set of clinical, instrumental and laboratory methods, and the ankle-brachial index (ABI) was measured. The eGFR was calculated by the CKD-EPI formula. Depending on the severity of non-cardiac arterial stenoses, the following groups were identified: <30%; 30-49%; 50-69%; 70-99%; occlusion; absence of stenosis. The criteria for the atherosclerosis progression was the presence of at least one of the following: the transition of stenosis from one group to another; decrease in initially normal ABI <0,9; decrease in ABI initially abnormal (<0,9) by more than 10%. For the analysis, two groups were identified: group 1 (n=375) without progression and group 2 (n=129) with progression of atherosclerosis.

Results.Preoperatively, the number of patients with eGFR <60 ml/min/1,73 m2 was equal in both groups. At both control points, eGFR was higher in 1 group (p=0,072 and 0,025, respectively). During the year, eGFR increased in both groups with significant differences among first one (p<0,001). One year after the operation, eGFR positively correlated with ABI (p=0,004) and with total and low-density lipoprotein cholesterol levels. Polyvascular disease determined from 30% of stenosis, was negatively associated with preoperative and annual eGFR (p=0,011 and p=0,004, respectively) and from 50% — with eGFR calculated one year after CABG (p=0,006).

Conclusion.In patients with progression of non-coronary atherosclerosis 1 year after CABG CKD-EPI eGFR was lower compared to patients without progression. In the long-term period the estimated values of renal function are significantly higher in patients without atherosclerosis progression.

Aim.To determine the severity of chronic kidney disease (CKD) in patients after acute coronary syndrome (ACS).

Material and methods.The study was conducted in Semey (Semipalatinsk), East Kazakhstan region. The case histories of patients with ACS who were admitted to the University Hospital of the State Medical University (Semey State Medical University) of the East Kazakhstan Region for 1 year were studied. A total of 659 case histories were analyzed, of which 263 were patients with myocardial infarction (MI), and 396 were patients with unstable angina (UA). The diagnostic criteria for CKD were: proteinuria, levels of creatinine, glomerular filtration rate (GFR) <60 ml/min/1,73 m2. CKD stage was determined by the parameters of GFR.

Results.The average proteinuria in patients with MI (Me=0,033) were higher than in patients with UA (Me=0,00), U=39564,5, Z=-5,579 p=0,000. The average values of creatinine in patients with MI were 10,26 mmol/l higher than in patients with UA (t=3,333, df=657, p=0,001). The mean GFR values in patients with MI were lower by 4,69 L/min/1,73 m2 than in patients with UA (t=-3,794, df=657, p=0,000. The highest percentage of CKD in patients with ACS were in stage 2-3, the second stage of CKD was more often diagnosed in patients with UA.

Conclusion.The results of study allowed us to characterize the severity of CKD in patients undergoing ACS. We consider that widespread introduction of international and national clinical guidelines on the diagnosis, treatment and prevention of CKD in patients undergoing ACS is needed.

Material and methods.The study enrolled 57 patients: 16 of them underwent 64-slice computed tomography — included retrospectively, 34 — prospectively, with a 640-slice CT scan. Specialists from the Laboratory of Mathematical Modeling processed CT images and evaluated noninvasive FFR. Ischemia was confirmed if FFR <0,80 and disproved if FFR ≥0,80. After that the prospective group of patients was hospitalized for invasive FFR assessment as a reference standard; if ischemia was proved, patients underwent stent implantation. In the retrospective group, patients already had invasive FFR values estimated. Statistical analysis was performed using R programming language packages (cran-r.project.com). Continuous variables are presented as mean values ± standard deviations, order variables are presented as medians with interquartile ranges in parentheses. We used the D’Agostino-Pearson omnibus test for the assessment of normality of distribution; a Q-Q Plot was also constructed. We performed the Bland-Altman analysis and ROC-analysis for comparison of these two methods, and the Pearson’s chi-squared to assess the degree of correlation.

Results.During data processing, 3 patients of the retrospective and 34 patients of the prospective group were excluded from the study. The sensitivity of our method was 90,91% (95% CI; 58,72-99,77), specificity — 86,67% (95% CI; 59,54-98,34), P<0,05, accuracy — 88,46 (95% CI; 69,85-97,55) — in per-vessel analysis. In perpatient analysis, the sensitivity was 91,67% (95% CI; 61,52-99,79), specificity — 80% (95% CI; 28,36-99,49), (P<0,05); accuracy 88,24 (95% CI; 63,56-98,54).

Conclusion.Our method has quite a high accuracy and can be successfully used in clinical practice in order to enhance the diagnostic efficiency of the CCTA.

Aim.To identify the criteria for reversibility of structural changes in the myocardium of patients with coronary artery disease after revascularization based on analysis of data obtained using magnetic resonance imaging (MRI).

Materials and methods.We studied the long-term results of surgical treatment of 53 patients with critical reduction of left ventricle contractile function (ejection fraction less than 30%) undergoing coronary bypass surgery. Before the operation, all patients underwent cardiac MRI and transthoracic echocardiography (EchoCG). Immediate and long-term results were assessed according to EchoCG.

Results.The average observation period was 25,0±15,4 months. We found that significant predictors of improving of left ventricle contractile function are diastolic interventricular septum thickness (according to EchoCG and MRI) >10,5 mm (p<0,05); diastolic posterior wall thickness (according to EchoCG and MRI) >9,5 mm (p<0,05); degree of initially scarred myocardium according to MRI <33 points (p<0,05).

Conclusion.Detection of a viable myocardium is a prognostically important sign of a possible improvement in the functional state of left ventricle after revascularization surgery in patients with coronary artery disease, complicated by a critical reduction of myocardium contractile function. Thus, this problem can be solved by contrasting MRI.
Possible associations between recovery aerobic training and increasing the length of telomeres
Authors: Aronov D. M.
Published: April 2019

It is known that in recent decades, methods of cardiac rehabilitation have been widely used in patients after acute myocardial infarction, coronary syndrome and cardiac operations. The main active factor in cardiac rehabilitation is a program of physical training. On the other hand, it has been established that physical training and/or sufficient physical activity positively affects the length of human telomeres. It is assumed that under the influence of cardiac rehabilitation, the improvement in the course of the disease may be due to an increase in telomere length. We found studies with such positive associations. This primarily concerns people with prediabetes, overweight, multiple risk factors. We established the importance of training in physically active people, athletes, especially with great sports experience. It seems promising to perform studies (training/telomeres) in patients with history of acute myocardial infarction, acute coronary syndrome and cardiac surgery.
Género e inclusión financiera en Colombia
Authors: Cardona Ruiz Daniel Elifonso , Hoyos Maria Camila , Saavedra-Caballero Fabiola

El acceso al sistema financiero formal permite a las personas organizarse financieramente, ahorrar y planear para el futuro; sin embargo, todavía es alto el porcentaje de la población colombiana que se encuentra fuera de dicho sistema, en especial las mujeres. El objetivo del presente trabajo es medir, a través de un modelo econométrico alimentado con datos de 2014, del Global Findex Database del Banco Mundial, las diferencias de género en términos de inclusión financiera en Colombia en ese año. Para esto, se tienen en cuenta tres categorías que miden a) el acceso a servicios de una institución financiera formal, b) su uso activo, y c) el uso activo de servicios financieros informales. Esta última categoría cobra relevancia, ya que tiene en cuenta aquel segmento de la población que se encuentra marginado de los servicios formales del sector financiero. En términos generales, se evidencia que ser mujer tiene un impacto negativo para una persona al momento de ser incluido en el sistema financiero formal, entendiendo “inclusión financiera” como el acceso y uso efectivo de servicios financieros formales.

Sanger sequencing is the standard preclinical method used for sequence verification of AAV transfer vector cloning constructs and eventual packaged viral genomes. While Sanger sequencing does provide high quality data in a relatively short turnaround time, the data analysis requires manual evaluation of sequencing reads, rendering this approach incredibly low-throughput. Additionally, Sanger sequencing only provides 1-2X coverage, which results in low confidence single nucleotide polymorphism (SNP) and indel calling. It is imperative for preclinical gene therapy labs and core facilities to sequence both the transfer vector plasmids that go into viral production and the eventual packaged genomes to ensure no recombinations or mutations have occurred, and to validate that the genomes were not truncated during capsid packaging. This protocol outlines a simple, fast, and inexpensive methodology geared toward preclinical environments for sequencing packaged AAV genomes via NGS, using paired-end Tn5 tagmentation-based library preparation. This protocol was optimized for use on the commonly available illumina MiSeq instrument, but other instruments would also work and should be chosen based on the number of samples and depth required (iSeq 100, MiniSeq, MiSeq, NextSeq, etc.).

Published: April 2019

Okuma; geçmişten günümüze seslendirme, anlama, kavrama ve yapılandırma ile ilişkilendirilerek tanımlanmıştır. Günümüzde ise okuma, üstbilişsel bir süreç olarak nitelendirilmekte ve bu süreci denetlemeyi temel almaktadır. Yetkin bir okurdan beklenen, belirli bir okuma amacıyla metne yaklaşıp okuma eylemi süresince artalan bilgilerini işe koşarak metne özgü yapıları anlamlandırabilmesidir. Bu yetkinlikler de metin türüne özgü üstbilişsel okuma stratejilerini işletmeyi gerektirir. Farklı üstbilişsel okuma stratejileri farklı okuma yöntem-teknikleriyle uygulanabilir. Bu bağlamda çalışmanın amacı, metin türlerine uygun üstbilişsel okuma sırası stratejileri ve okuma yöntem-tekniklerini ilişkilendirip etkinlik önerileri sunarak okuma eğitimi için ders araç-gereci gelişimine katkıda bulunmaktır. Yazınsal ve bilgilendirici metinlerin özelliklerini yansıtmaları ve ders kitaplarında sıklıkla kullanılmaları nedeniyle araştırmada, amaçlı örnekleme yöntemlerinden ölçüt örnekleme bağlamında öykü, şiir ve makale türleri ele alınmıştır. Betimsel bir araştırma olan çalışmada Dilidüzgün, Çetinkaya-Edizer, Ak-Başoğul, Karagöz ve Yücelşen (2018) tarafından hazırlanan metin türü bağlamında üstbilişsel okuma sırası stratejileri ile okuma yöntem-tekniklerinin ilişkilendirildiği çizelge kılavuz olarak seçilmiştir. Çalışma sonucunda araştırma kapsamına alınan üç metin türünün, okunma amacı doğrultusunda üstbilişsel okuma sırası stratejileri ile okuma yöntem-tekniklerinin kullanımı bağlamında ortaklıklar ve farklılaşmalar taşıdığı bulgulanmıştır. Bu ortaklık ve farklılaşmalar doğrultusunda belirtke tabloları hazırlanmış, etkinlikler belirtke tablolarından yola çıkılarak oluşturulmuştur. Oluşturulan bu etkinlikler, öneri niteliğinde olup uygulamalı çalışmalarla genellenebilirliğinin artırılacağı düşünülmektedir.
