Orange Dye Thin Film Electrochemical Hygrometers
Authors: Karimov Kh.S. , Shahid M. , Moiz S.A.
Published: July 2017

Electrochemical hygrometers have been fabricated using orange dye (OD) C17H17N5O2 thin films, deposited from aqueous solution under normal conditions. The films were deposited on zinc substrates from 10 wt.% solution of OD in distilled water. These films were than used to make samples of Zn/OD-TP/Cu, Zn/OD/Cu and Zn/OD/Graphite (TP stands for tissue paper); copper electrode was used in the form of a mesh and the graphite in the form of a porous solid. Properties of the samples were investigated in a range of 46-78% humidity. Output voltage and current of the sensors were monitored in electrochemical mode of operation, showing a rise of 8 and 100 times, respectively, with an increase in humidity. These electrochemical hygrometers may be potentially useful for developing humidity meters.

Authors: Golovko A.K. , Kamyanov V.F. , Filimonova T.A.
Published: July 2017

Specific properties of ozonolysis products of high-molecular heteroatomic compounds (resins and asphaltenes) from crude petroleums and natural bitumens are described. It is shown that polyfunctional carboxylic acids or their salts obtaining by alkaline hydrolysis of ozonization products of heavy petroleum
stocks permits to produce manifold useful novelties such as high-effective demulsifiers for petroleum dehydration process instead of expensive synthetic demulsifying reagents; water-soluble organic astringents suitable for chemical land-reclamation or to prepare moulding mixtures at the foundries; oily or emulsion
lubricating coolants for metal-working tools; stimulators of soil microorganisms activity and plant growth. The new chemical products of petroleum origin are not inferior to the best synthetic reagents for the same destinations but differ from the lasts advantageously on account of the simplicity of their production technology and low cost. The optimal expenses and other principal technological parameters were established both for raw material ozonization, following alkaline treatment and final product isolation stages of the production process for each new reagent described. By means of numerous laboratory experiments and field tests performed with seeds, bulbs and grafts of different agricultural plants and with ozonolysis products produced from the resinous components of different crude petroleums it was proved that high biological activity is characteristic only of the substances obtained from high-molecular compounds from low-sulfur naphthenic crude petroleums and natural bitumens occurring, as a rule, at small burial depths. These ozonolysis products are very effective stimulants for the different plants growth, suitable for a treatment of different forms of planting materials and providing significant acceleration of early growth stages, the reduction of vegetation and ripening periods, and the increase of total productivity of agricultural plants.
No es mi culpa, fue mi cerebro. ¿Es esta una afirmación válida para aplicar la inimputabilidad a individuos con trastornos de la personalidad y psicópatas?
Authors: Jiménez Martínez Custodia
Published: July 2017

En este artículo se aborda el estudio de la responsabilidad jurídica e inimputabilidad de los delitos cometidos por individuos con trastornos de la personalidad y psicópatas, así como los supuestos que se han desarrollado en más de una treintena de años en las neurociencias para refutar un concepto fundamental del Derecho Penal moderno, esto es, el pensamiento de que en el hombre existe libertad para actuar y decidir su conducta ilícita. Bajo el esquema de la neurociencia no existiría la aludida libertad, puesto que esta sería un espejismo ya que el cerebro ordenaría previamente nuestra conducta.
Polska terminologia językoznawcza w węgierskiej tradycji polonistycznej
Authors: Seretny Anna , Stefańczyk Wiesław Tomasz
Published: July 2017

Polszczyzna i język węgierski są językami odrębnymi zarówno pod względem genetycznym, jak i typologicznym. Język polski jest językiem indoeuropejskim, słowiańskim, fleksyjnym, natomiast węgierszczyzna jest językiem uralskim, ugrofińskim, aglutynacyjnym. W związku z tymi odrębnościami część kategorii gramatycznych w pełni się nie pokrywa. Dotyczy to zwłaszcza nieistniejącego w węgierszczyźnie rodzaju gramatycznego, liczebnika zbiorowego, przyimka, aspektu czasownika, a także w odmienny sposób wyrażanego przypadka. W węgierskim językoznawstwie polonistycznym istnieją usankcjonowane tradycją terminy nazywające wskazane kategorie. Niniejszy artykuł jest poświęcony ich analizie.

O preconceito linguístico como barreira à inclusão digital
Authors: Silva Octavio Augusto Bueno Fonseca
Published: July 2017

A internet, sobretudo no Brasil, tem se expandido rapidamente. Um dos combustíveis para a chegada de novos usuários são os dispositivos portáteis, como smartphones e tablets. Esses dispositivos, além de mais acessíveis que os computadores tradicionais, também contam com internet móvel, que além de barata, chega a qualquer bairro, quebrando as barreiras da infraestrutura, pois ainda hoje não há internet banda larga em muitos bairros de regiões periféricas. Que mudanças, portanto, tem sofrido o ambiente virtual, com a introdução desses novos atores, onde, sabidamente, a maioria deles é de baixa renda e está desembarcando em um território que só era acessível apenas para pessoas de maior classe econômica e social? Veremos neste trabalho de conclusão de curso, defendido no IEL em Dezembro de 2014, que um dos problemas é o preconceito linguístico, que se dá quando uma pessoa é silenciada, agredida ou excluída, porque emitiu um discurso fora da norma padrão do português. Através da análise de interações em sites de compras, vídeos e redes sociais, mostrarei que, ainda que a internet elimine muitas fronteiras de exclusão e distanciamento que existem no mundo real, como bairros, na prática, o discurso permanece como principal forma de exclusão, sendo que o preconceito linguístico é ainda mais evidente nesse meio, pois na ausência de outros elementos para caracterizar a classe social da pessoa, o foco é posto no modo como ela escreve, e, escrevendo fora da norma padrão, essa pessoa é automaticamente excluída, uma vez que o preconceito linguístico é também preconceito social.

O progresso técnico encontrado em uma Unidade de Terapia Intensiva Neonatal permite a sobrevivência e internação de bebês com doenças graves, prematuros extremos e malformações. Neste contexto, o atendimento psicológico aos pais é de extrema importância, uma vez que este período é percebido pelos mesmos como um momento de crise, de angústia e de intensas vivências emocionais, que podem gerar desordem e sofrimento psíquico. Desta forma, o objetivo deste trabalho é descrever e compartilhar a atuação da psicologia na unidade de Neonatologia do CAISM/UNICAMP. Os atendimentos aos pais são realizados de forma individual e/ou em grupo, destinados ao suporte emocional e auxílio no processo de aproximação e construção do vinculo afetivo entre eles e o bebê. Os mesmos são atendidos desde a entrada do filho na unidade, ou antes, no período gestacional quando os riscos de prematuridade ou internação são expressivos. A visita dos irmãos é estimulada e acompanhada através de breve avaliação pré e pós entrada dos mesmos à unidade. Em caso de óbito neonatal, o psicólogo atua no acolhimento, permitindo a expressão dos sentimentos e garantindo um momento de privacidade e despedida ao filho. Desde 2014, a psicologia vem ganhando um espaço de atuação na unidade, promovendo à possibilidade de escuta e apoio, minimizando danos e possíveis traumas as famílias. A atuação do psicólogo na UTIN é essencial para que os pais possam elaborar sentimentos e vivências do período, além de potencializar o vínculo entre pais/bebês e a comunicação entre pais/equipe.

Staged embolization of high-grade Spetzler-Martin AVMs gains popularity. The assessment of AVM devascularization degree depends on a specialist's personal experience and is very subjective. The goal of our study was to develop software for accurate and objective calculation of AVM devascularization percentage. 34 patients underwent a partial AVM embolization procedure using both adhesive and non-adhesive embolic material. Their pre- and postoperative DICOM angiographic images were assessed by both 4 skilled interventional radiologists and by our new software. We compared the evaluations of AVM devascularization degree made by the software and the specialists. 54 tests were performed. The software was based on a LabVIEW tm platform. The degree of AVM devascularization was estimated in percent values. Mean difference of values was 14,8% 1,6 (range 0%-40%) between human estimations and 3,4% 0,4 (range 0,7-9,2%) between computer calculations. Reliability of the samples was estimated by Kolmogorov-Smirnov criterion. Critical value of the criterion was 2 = 4,89, which corresponds to p value < 0,01. The new software demonstrated adequate efficiency and accuracy to be used for standardization of AVM devascularization degree evaluation.

To assess proarrythmogenic effects after different techniques of radiofrequency catheter ablation, 427 patients with paroxysmal, persistent, and long-standing persistent atrial fibrillation (AF) were examined. The patients were randomized into four groups: antral pulmonary vein isolation (PVI) (Group I), PVI plus roof line and mitral isthmus ablation (Group II), anatomic ablation of ganglionated plexuses (GP) of the left atrium (Group III) and GP plus PVI (Group IV). At the end of follow up (34,43,2 months) the largest number of proarrythmogenic effects was observed in Group II, 24,8% (26 patients). In the remaining groups the percentage of proarrythmogenic effects did not exceed 11%, neither was there any significant difference among Groups I, III and IV. Thus, the creation of additional linear lesions in the left atrium is a predictor of proarrythmogenic effects during follow up.

The Ross procedure outcomes in patients with left ventricular dysfunction are presented. 20 Ross procedures were performed in patients with aortic disease complicated by severe left ventricular dysfunction. The average left ventricular ejection fraction before surgery was 31,56,57%. Aortic stenosis was found in 60% of cases. Hospital mortality rate was 5%. Heart failure prevailed among complications. It was already in the early postoperative period that significant left ventricular remodeling was observed. The patients with aortic stenosis demonstrated a 56,9 % increase in ejection fraction, while their end-systolic diameter and end-systolic volume decreased by 34,5% and 13,3% respectively. In the group with aortic insufficiency there was a statistically significant reduction in the left ventricular volume indices: left ventricular end-diastolic diameter by 20%, left ventricular end-diastolic volume by 36,5%. No reoperation due to dysfunction of the autograft and conduits in the pulmonary artery area was required. At 12 months after surgery the processes of left ventricular cavity remodeling and normalization of contractility in both groups continued. The results of this study show that the Ross procedure can be used successfully in patients with severe left ventricular systolic dysfunction.

Published: July 2017

We analysed results of left atrial and biatrial anatomic scheme of radiofrequency (RF) ablation of the atria in patients with valvular heart. From 2007 to 2011, RF ablation procedure performed 283 patients with atrial fibrillation and heart valve disease. Patients were divided into two groups - group I performed a complete circuit biatrial procedure (procedure maze IV) - 131 patients, in group II only ablation of the left atrium -152 patients. Most of the patients had long-term persistent AF. The main problem of early postoperative period is dysfunction of pacemaker complex, which observed in 64.9% and 50.7% patients for group I and II, respectively (p = 0.031). Permanent dysfunction of pacemaker complex required implantation of permanent pacemaker (9.2% and 4.6% of cases for group I and II, respectively, p = 0,023). Predictors of dysfunction of the pacemaker complex were biatrial execution method and duration of AF. Freedom from AF and AT during 36 months after surgery was 80.4% for patients in group I and 78.5% for patients in group II, with no statistically significant difference (log-rank test, p = 0.621). Atrial transport function has not revealed that the active fraction of the right atrium was 29.8% higher than in group II in the early postoperative phase and by 17.9% in the long term, with no difference between groups for the left atrium has been received.

The article analyzes the neurological complications after interventions on the ascending aorta and the aortic arch in dissection I type by De Bakey. Group of authors investigated over a decade of experience in surgery of aortic dissection in both acute and chronic. Authors estimated the incidence of neurological complications after surgical intervention in 124 patients in the early post-operative and long term period. It were studied both qualitative measures (methods of reconstruction of the aortic arch, type of cerebral perfusion, the etiology of the pathological process, comorbidities) and quantitative (the duration of the different stages of surgery, age, height, weight). The analysis revealed that almost all cases of strokes were observed in the older age group and were associated with concomitant occlusive-stenotic arterial lesions caused by Takayasu's syndrome and atherosclerosis, as well as a set of related diseases. Increase in the number of strokes contribute to more complex, and therefore more time-consuming intervention types of reconstruction of the aortic arch. Antegrade perfusion of the brain, to our knowledge, did not have statistically significant advantages over retrograde perfusion or hypothermic circulatory arrest of the brain.

More than 50 years have passed since the first successful heart valve replacement. Since then, many types of mechanical prostheses have been introduced. The prosthesis choice for the replacement of an affected valve is a major concern in valvular surgery. The introduction of a new heart valve prosthesis requires accurate data collection and data processing for a long follow-up period. In present article we sought to compare modern commercial available bileaflet foreign mechanical valve prosthesis for their long follow-up with Russian mechanical valve for aortic and mitral valve replacement.

Our prospective, randomized, simple-blinded, pilot study investigates the influence of fluid therapy by using balanced crystalloid solution, 4% solution of gelatin polysuccinate, and 6% hydroxyethyl starch 130/0.42 on the extravascular lung water content in patients with coronary artery bypass grafting surgery. The aim of fluid therapy was to maintain a global end diastolic volume index within 680-850 ml/m 2. Transpulmonary thermodilution was used to determine an extravascular lung water index. Saturation of mixed venous blood, lactate, fluid balance, and hemodynamics were also investigated. It was shown that fluid therapy with the use of balanced crystalloid solution does not enhance the extravascular lung water content as compared with the use of colloid solutions. To achieve appropriate oxygen delivery, the effective infused volume of crystalloid solution was the double of that of colloid solutions.

To evaluate the efficacy and safety of ablation of ventricular tachyarrhythmias located in the pulmonary artery (PA), the data on 248 consecutive patients with ventricular tachycardia (VT) or premature ventricular contraction (PVC) of the right ventricle (RV) were analyzed over a period from February 2008 to March 2013. Localization of PVC/VT from LA was observed in 16 (6.5%) patients. The primary endpoint of the study was the absence of PVC/VT during long-term follow-up after a single and multiple ablation procedures. The secondary endpoints were surgery complications, the number of PVCs obtained by Holter monitoring during follow-up. The follow-up was 42.56.4 months. The longterm effectiveness of ablation of PVCs/VT from LA after one or more ablation procedures without the use of AAD was 93.8% and 100 % respectively. There were no postoperative complications in this group of patients. Neither cases of injury to the valve or wall of the pulmonary artery, nor spasms of the coronary arteries or other injuries were recorded. Average number of PVCs obtained by 24-hour Holter monitoring was 784 642 (range from 2 to 4000) as compared to 18371 12282 prior to surgery (p<0.001). In patients with ventricular tachyarrhythmias localized in the region of the pulmonary valve, radiofrequency ablation is a highly effective and safe treatment in the long-term follow-up.

The principles of organization of perinatal diagnostics of congenital heart disease (CHD) carried out by the advisory group of the cardiac center are presented. 1 601 pregnant women at the age from 18 to 40 years and 20 to 38-39 weeks of gestation were examined. 657 (41%) of them had risk factors of CHD development, while 336 (21%) were diagnosed with congenital heart disease. Only 19.1% of pregnant women with CHD fetus had risk factors, with no such relation observed in other women. Surgical repair was performed in 56.4% of cases during a newborn period. A three-stage system of perinatal diagnostics of congenital heart disease performed by the cardiac center's experts over prenatal and neonatal periods allows providing consistency and efficiency of rendering assistance to newborns with congenital heart disease.

Factors associated with right ventricular (RV) dilatation in patients with prior Q-wave myocardial infarction (MI) have been determined. Out of 16839 patients from Register of performed coronary angiography we selected those with prior Q-wave MI who had no congenital heart disease: 1263 patients without RV dilatation and 99 patients with RV dilatation. There were more males in the group with RV dilatation (97.0 vs 89.6%, p = 0.018). Mean body mass index (BMI) was higher in this group (31.05.1 vs 29.44.6 kg/m 2, p = 0.003). Patients with RV dilatation more often had a higher New-York Heart Association (NYHA) functional class (III/IV - 50.5 vs 17.4%) and arrhythmias (45.5 vs 17.8%, both p<0.001). Mean left ventricular (LV) mass index determined by echocardiography was higher in patients with RV dilatation (168.444.5 vs 136.031.0 g/m 2). This group often demonstrated a reduced LV systolic function (71.7 vs 32.9%) and significant mitral regurgitation (52.5 vs 12.4%, all p<0.001). There were less frequent lesions of the diagonal branch of the left circumflex artery in patients with dilated RV (5.1 vs 12.1%, p = 0.035). According to our mulrivariate analysis, RV dilatation was predominantly associated with male gender, increased BMI and parameters describing the severity of LV dysfunction and remodeling.

In order to clarify the state of physical performance of young patients with signs of poorly differentiated connective tissue dysplasia (CTD) in comparison with morphometric and functional performance of the heart, an open comparative study was conducted. Speckle tracking (ST) echocardiography was applied for quantitative evaluation of deformation properties of the right ventricle (RV) free wall. The study included 549 patients with CTD (330 men, mean age 23.51 8.67). An average diagnostic coefficient of CTD was 28.8410.76. The main symptoms were CTD changes in the musculoskeletal system (n = 549), cardiovascular system (n=409), skin (n=169) and respiratory system (n=119). 44 patients with CTD and low exercise tolerance and 13 healthy volunteers were tested by using a speckle tracking technique. In the group of patients with CTD a significantly higher incidence of low exercise tolerance and dystonic reactions to physical exertion were observed. Also recorded were changes in the ST-parameters of RV systolic strain.

Currently gram-negative bacteria are recognized as the most problematic pathogens. The authors studied the incidence of bacteremia caused by gram-negative microflora and its sensitivity to antibiotics in patients who underwent cardiac surgery. We analyzed the results of blood tests over a period of 5 years, from 2007 to 2011. During this period, 216 strains of gram-negative bacteria were identified. Enterobacteria accounted for 57.4% (124) of the structure of the gram-negative flora, while 42.6% (92) were glucose non-fermentative gram-negative bacteria. The prevailing pathogens detected when studying cardiac patients' blood were K. pneumoniae (25.5%) and P. aeruginosa (15.3%). The infections caused by K.pneumoniae are most efficiently treated by using carbapenems. As for P. aeruginosa, the most efficient antibiotics to fight this pathogen are piperacillin/tazobactam, amikacin, netilmicin. Carbapenems should be prescribed only after the sensitivity of microorganisms to these antibiotics is determined.

Systemic inflammatory response was first determined in 1980 and cardiac surgeons turned to it in 1996. At present, there are a lot of publications on this issue, however, the extent of operation and duration of CPB are considered in clinical practice as crucial indicators of severity of patient's condition following cardiac surgery. In our study we tried to look at this problem from a different perspective and draw a parallel between the severity of patient's condition resulting from operational trauma and CPB. We included 48 patients who under-went cardiac surgery under CPB. Plasma levels of procalcitonin (PCT), lactate and interleukin-6 were investigated before the operation, after CPB and at 24 hours. Also revealed was the relationship between the plasma levels of IL-6, lactate and PCT (r = 0.53; p = 0.000 in both cases). The level of PCT at the 3rd stage was found to relate to the duration of CPB (r = 0.4; p = 0.005), ALV (r = 0.44; p = 0.001) and length of stay at ICU (r = 0.53; p = 0.000). We didn't manage to find any relationship between the length of stay at ICU and the duration of CPB. Correlation between the PCT plasma level and the duration of intensive care indicates the importance of dynamics of the given biomarker for early prediction of follow-up course after open-heart surgery.

The purpose of our prospective, consistent, non-randomized study was to analyze the results of vasoreactivity tests (VRT) performed with nitric oxide (NO) or inhaled Iloprost in heart transplant candidates. 72 VRTs were done in 58 candidates for heart transplantation. All patients had heart failure III-IV NYHA and pulmonary hypertension (PH) with pulmonary vascular resistance (PVR) over 2.5 WU. 43 patients received NO, 80 ppm for 20 min. 29 patients inhaled 20 g of Iloprost (Ventavis, Bayer). Hemodynamic parameters were measured at baseline, 20 min after NO inhalation and 15 min following the completion of Iloprost inhalation. There were no between-group differences in the severity of patient's condition and baseline hemodynamic indicators. Both vasodilators caused statistically significant reduction in mean PAP: in the NO group it dropped (p = 0.002), in the Iloprost group the mean PAP decreased (p<0.0001). A more than 20% decrease in PAP was recorded in 13 cases (30.2%) in the NO group and in 16 cases (55.2%) in the Iloprost group (p = 0.03). A more than 20% decrease in PVR was noted in 24 cases (55.8%) in the NO group and in 24 cases (82.8%) in the Iloprost group (p<0.02). We found some differences in the effect of NO and Iloprost on LV efficiency. There were no changes in the stroke volume index (SVI) in the NO group, while inhaled Iloprost increased SVI (p<0.001). A probable cause of the increase in LV efficiency might have been the reduction of total peripheral vascular resistance (p<0.0001). There were no differences in SVI during NO inhala-tion. It should be noted in conclusion that Iloprost is more effective in decreasing mean PAP and PVR in heart transplant candidates. Inhaled Iloprost causes favorable changes in preload and afterload of the impaired LV and increases its performance.

Authors: Mareev Yu. V.
Published: July 2017

Chronic heart failure is a condition with high mortality and morbidity. Cardiac contractility modulation (CCM) is a modern method for treating patients with CHF. There is evidence that CCM improves quality of life and exercise tolerance of patients. There is no sufficient data that MCC can improve a patients prognosis. We need more data to understand the place of MCC in treatment of patients with CHF.

Published: July 2017

The aim of this study was to measure the accuracy of noninvasively obtained ventricular activation (isolated epicardial vs combined endo-epicardial mapping) as compared with that of standard invasive mapping in patients with ventricular arrhythmias. 94 patients (35 males and 59 females) aged 20 to 67 years (mean age 42.6 years) with ventricular arrhythmias of different localization and etiology and 8 patients (4 males and 4 females) aged 21 to 65 years (mean age 48.8 years) with atrial arrhythmias were examined. All patients underwent noninvasive electrophysiological examination, which was performed with Amycard System, subsequent intracardiac mapping and radiofrequency catheter ablation. The arrythmogenic focus localizations coincided in 83 cases, in 11 patients with ventricular arrhythmias some variances were observed and in patients with atrial arrhythmias no such variances were found. Thus, the accuracy of noninvasive mapping turned out to be 89.2%.

Authors: Li Yanlin , Ji Guobiao , Xu Xiaodong , Wang Juan , Li Yingying , Tan Feifei , Li Xiangdong
Published: July 2017

Background:

PRRSV features with genetic diversity and high mutation which leads to the emergence of a multiple of circulating virus strains with different virulence. North American (genotype 2) PRRSV (NA-PRRSV) can be divided into classical PRRSV (C-PRRSV), highly pathogenic PRRSV (HP-PRRSV), and NADC30-like PRRSV (NL-PRRSV) according to their genomic characteristics and pathogenicity. So far, the above three subtypes of NA-PRRSV are now circulating in China.

Objective and Method:

In this study, a reverse transcript polymerase chain reaction (RT-PCR) was established to simultaneously differentiate three subtypes of NA-PRRSV. The established RT-PCR can be applied to PRRSV-infected samples originated from both supernatant of cell culture and pig tissues and showed specificity exclusively to PRRSV. The sensitivity of RT-PCR showed the minimum RNA detection was 0.04ng/µl.

Result and Conclusion:

The established RT-PCR was next used to differentiate the subtypes of 29 NA-PRRSV isolated in 2016 and the results showed that HP-PRRSV is still the dominant circulating virus strain in the presence of NADC30-like PRRSV in Henan province.
