A experiência discursiva e a singularidade: levantamento de questões no campo da aquisição de linguagem
Authors: Carvalho Glória , Rozental Eva
Published: March 2019

The present paper is an attempt to discuss the relationship between shared discursive experience and the child’s singular speech, at an early stage of his/her linguistic course. The infant’s unusual utterances were selected and taken as units of analysis, that is, the types of utterances which are unfamiliar to the adult, thus highlighting the singularity aspect. By confronting verbal data of a diad (mother-child), the relevance of considering the discursive experience background between the two speakers stood out within the study of the changes occurring in the subject, from his/her condition of non-speaker into a new condition of speaker. Nevertheless, there is an indication that there would be a language movement towards two poles: metaphorical and metonymical. These would act on such discursive experience, making it return, in the child’s utterances as a different, singular structure.

Comunicação intercultural: uma desconstrução e reconstrução de um termo inflacionário.
Authors: Schröder Ulrike
Published: March 2019

Although the term intercultural communication becomes more and more important in scientific discussion originated in distinct areas which are interested in intercultural research, a theoretical and epistemological foundation conceptualizing the term in an appropriate way and considering an analysis of its constitutes rarely can be found. Therefore, first, the term in question is deconstructed by asking for a reasonable understanding of culture and communication. Subsequently, the term will be reconstructed according to the conclusions made, focusing on the question to what extent it might be really possible to talk about a strict delimitation between intracultural and intercultural communication.

Published: March 2019

The efficiency of the solar PV panel decreases significantly as the PV panel’s operating temperature increases. There are many cooling techniques might be suitably deal with this problem to enhance the solar panel efficiency. The presented cooling technique used for solving the PV panel’s temperature elevation is an active close loop cooling system, accomplished using two water glazing chambers made from acrylic glass placed at the PV panel surfaces (rear and front). These champers are utilized for cooling down the PV cell’s temperature, as well as filtering the useful sunlight spectrum. The results show that the PV cell’s temperature reduction by 50.06% with using the cooling system, this leads to an average increase in the maximum output power and consequently electrical efficiency of the PV panel by about 12.69% and 14.2%, respectively.

Published: March 2019

La contaminación ocasionada por hidrocarburos representa un riesgo para el medioambiente. Se han enfocado estudios en la búsqueda de alternativas para contribuir a revertir su efecto. Una de ellas involucra el uso de microorganismos nativos capaces de persistir en ambientes contaminados. Por lo cual el objetivo de este trabajo fue analizar el potencial de biotipos de Azospirillum brasilense para degradar compuestos xenobióticos como fenantreno, xileno, tolueno y naftaleno. Se caracterizó la producción de biosurfactantes, se evaluó in vitro la capacidad de tolerancia a hidrocarburos derivados del petróleo y búsqueda de genes relacionados con la degradación de compuestos aromáticos mediante el programa RAST. Los resultados mostraron que los biotipos produjeron biosurfactantes y se seleccionaron cinco de ellos para realizar ensayos de tolerancia a xileno, tolueno, fenantreno y naftaleno; en los cuales no se observó crecimiento bacteriano después de 216 horas de incubación a 30 °C. Se registraron 19 secuencias codificantes relacionadas con la degradación de compuestos aromáticos; de las cuales 11 están asociadas con el metabolismo de los compuestos intermedios aromáticos centrales y 5 con las vías catabólicas periféricas cuya función se asocia con las rutas de degradación de quinato, benzoato, salicilato, gentisato y tolueno.

“¿Quién inscribe a quién?”: sangre, tinta, y deconstrucción
Authors: Martell James
Published: March 2019

Si en la Antigua Grecia la “injusticia” tomaba la forma de una mujer tatuada, Adikia, y si, según Derrida, “la deconstrucción es justicia” o, en otras palabras, Dike, ¿podríamos entonces hablar—siguiendo esta tradición—de un tatuaje deconstructivo o derrideano? El corpus derrideano lleva una buena cantidad de tatuajes en el cuerpo. Algunos son externos, como frases de otros tatuajes o cuerpos tatuados; otros son internos y describen sus propias extremidades, como las columnas de Glas. Frente al principio clave de visibilidad a través de la invisibilidad de nuestra era, la sangre y la tinta del tatuaje son, tal vez, la respuesta deconstructiva, o por lo menos el indicio de una respuesta a la ceguera de nuestras inscripciones. Estas inscripciones en cuerpo y en corpus (palabras e imágenes, papel y piel en múltiples superficies o pantallas) no reiterarán las fronteras (ese nunca ha sido el deseo de las tribus tatuadas). Sin embargo, podrían restructurarlas, convirtiéndolas en líneas de fuga deleuzianas y guattarianas “entre lo nacional y lo global e incluso entre lo terrenal y lo extraterrestre, entre el mundo y el universo” (Paper Machine 57), reproduciéndolas a través de múltiples inseminaciones de tinta, en lugar de limitar las superficies. En términos derrideanos, desarrollando una pluralidad de substratos por cada deseo de (una) khôra.

Associations between Empathy and Self-Conscious Emotions during Social Interactions
Authors: Gilchrist Jenna , Conroy David E. , Pincus Aaron L. , Ram Nilam
Published: March 2019

Empathy can alter the emotional state of an individual, yet little is known about how empathy impacts emotions in daily life. This study investigated how cognitive and affective empathy experienced during social interactions was associated with pride and shame. Participants (N = 150) between 19-89 years of age (M = 47.64, SD = 18.85) completed three 21-day measurement bursts of experience sampling every 4.5 months. Following each of 64,111 interactions, participants rated the intensity of two emotional states (proud, ashamed) and their experience of cognitive and affective empathy for their interaction partner. Results from multilevel models indicated that, at the within-person level, greater momentary cognitive empathy was associated with dampened shame and increased pride whereas greater momentary affective empathy was associated with increased shame and pride. At the between-person level, people who reported more cognitive empathy overall reported less shame and greater pride, and people who reported more affective empathy overall also reported greater shame but not any more or less pride. The emotional consequences differ based on the valence of the emotion experienced for cognitive empathy but not for affective empathy. Empathy is a dynamic process with different underlying processes for cognitive and affective empathy.

Similarity Leads to Correlated Processing: A Dynamic Model of Encoding and Recognition of Episodic Associations
Authors: Cox Gregory Edward , Criss Amy H.
Published: March 2019

We present a model of the encoding of episodic associations between items, extending the dynamic approach to retrieval and decision making of Cox and Shiffrin (2017) to the dynamics of encoding. This model is the first unified account of how similarity affects associative encoding and recognition, including why studied pairs consisting of similar items are easier to recognize, why it is easy to reject novel pairs that recombine items that were studied alongside similar items, and why there is an early bias to falsely recognize novel pairs consisting of similar items that is later suppressed (Dosher, 1984; Dosher & Rosedale, 1991). Items are encoded by sampling features into limited-capacity parallel channels in working memory. Associations are encoded by conjoining features across these channels. Because similar items have common features, their channels are correlated which increases the capacity available to encode associative information. The model additionally accounts for data from a new experiment illustrating the importance of similarity for associative encoding across a variety of stimulus types (objects, words, and abstract forms) and types of similarity (perceptual or conceptual), illustrating the generality of the model.
Measuring differential nodal distance using the Function Acquisition Speed Test
Authors: Cummins Jamie , Roche Bryan
Published: March 2019

Increasing evidence suggests that the relatedness of stimuli within the Function Acquisition Speed Test (FAST) methodology is sensitive to the learning histories of participants. For example, this method is sensitive to differences in the amount of baseline training provided to establish stimulus equivalence relations using arbitrary stimuli (Cummins et al., 2018a). However, it has not yet been investigated whether the relatedness of stimuli within the FAST varies based on differential nodal distances between stimuli within stimulus classes. If so, the FAST could serve an important adjunct assessment procedure for researchers who wish not only to assess the formation of stimulus classes using traditional methods, such as matching-to-sample, but also the relative relatedness of stimuli within complex stimulus classes (i.e., nodal distance). The current study sought to investigate this possibility. Participants (n = 16) were trained in the formation of two 4-member equivalence classes consisting of arbitrary nonsense syllables. Following this, participants completed three FAST assessments, each of which probed for the relatedness of stimulus pairs of differing nodal distance. Group- and individual-level analyses broadly demonstrated that relatedness varied as a function of nodal distances in pre-trained stimulus classes. However, results also highlighted some limitations of the FAST at the individual level.

Tree plants in the landscape have a very important function for the life of other living things. As an important element in the landscape, the selection of tree species in the landscape needs to be considered. With respect to aesthetic function in the landscape, the selection of tree species may vary based on their physical appearance. The general aim of this research is to study the potential of local tree collection at the Bogor and Cibodas Botanical Garden to fulfill the aesthetic function in the landscape. As for the specific purposes are as follows: (1) assess the ecological distribution of local tree collections of Bogor and Cibodas Botanical Gardens, (2) review the aesthetical performance of local tree collections of Bogor and Cibodas Botanical Gardens, and (3) provide recommendations on the utilization of Java native tree species for aesthetic functions in the landscape.This research was conducted at Cibodas Botanical Gardens and Bogor Botanical Garden. The research procedure is divided into 3 stages: (1) collection and grouping of tree data, (2) processing and analysis of tree data, and (3) assessment of tree aesthetic quality. The results of the processing and assessment of the tree data were used as a reference for the recommended tree species that are potential to be developed. Data of collected tree species were further processed and analyzed based on habitat distribution and morphological characteristics. Furthermore, the Key Performance Index (KPI) assessment technique is used to give value to each criterion. Stages of tree aesthetic quality assessment was done simulated using Scenic Beauty Estimation (SBE) method. Based on the research that has been done, the biodiversity of local tree species found in both botanical gardens is quite high as 223 species can be found in Cibodas Botanical Garden and 469 species can be found in the Bogor Botanical Garden. From this result, there are 52 species that can be found both at Cibodas Botanical Gardens and Bogor Botanical Garden. Then it can be concluded that the distribution of the habitat of local species of Java trees collection of KRB and KRC spread in each region. The highest number is a species of tree scattered throughout Java Island (327 species), from western Java (172 species), from west and central Java (80 species), central Java (21 species), central and eastern Java (13 species), western and eastern Java (11 species), and eastern Java (10 species). In addition, local tree species also have a range of habitat heights ranging from coastal zones (0 masl) to mountain zones (3100 masl). In the tree species studied in KRC and KRB, based on the criteria of aesthetic assessment there were 72 species of trees including into good category, 287 species in medium category, and 23 species in the bad category.
Heat-Stable Carbetocin Could Replace Oxytocin To Prevent Postpartum Haemorrhage Following Vaginal Delivery
Authors: Thapa Bikram
Published: March 2019

Postpartum haemorrhage (PPH) is the most common type of obstetric haemorrhage and accounts for 35% of all maternal deaths. World Health Organisation (WHO) defines PPH as: blood loss of 500 mL or more within 24 hours following vaginal delivery. PPH is the leading cause of maternal mortality in low-income countries, and the primary cause of nearly one quarter of all maternal deaths globally. Uterine atony is the most common cause of PPH accounting for more than 80% of causes. Thus, to prevent PPH, WHO has recommended active management of third stage of labor. All women giving birth should be offered uterotonics during the third stage of labor (as a part of third stage management) for the prevention of PPH; oxytocin (IM/IV, 10 IU) is recommended as the uterotonic drug of choice.

 

Conclusion: Heat stable carbetocin can be a breakthrough drug for overcoming heat degradation of oxytocin. Cold chain for storage or transportation of uterotonic drug is thus now not an issue. This single advantage can remarkably reduce the morbidity and mortality in low-income countries due to PPH as this drug can be made available even in most remote part of the country. Heat-stable carbetocin was studied aiming the developing countries. We can hope to see this drug in the new update in WHO recommendation for prevention of postpartum hemorrhage; that undoubtedly would be a very remarkable change, especially for resource limited countries like ours.

Published: March 2019

Introduction: Sustainable development goal 3 targets at ensuring healthy lives and promoting well-being for all at all ages. One of the component for achievement of this goal is improvement of maternal and child health; the indicators of which is perinatal mortality rate. The aim of this study was to evaluate the cause of perinatal death in a tertiary care medical centre, which may help to reduce the incidence of perinatal death and improve the quality of care.

Methods: A prospective study was done over a period of one year from April 2016 to March 2017. Causes of perinatal deaths based on PSANZ classification were recorded along with patients demographics and also avoidable factors were evaluated.

Results: Out of total 1275 deliveries, there were 21 perinatal deaths including three intrauterine foetal deaths, one still birth and seven early neonatal deaths. The perinatal mortality rate was 16.27 per 1000 birth. Majority of perinatal deaths (19%) occurred due to congenital anomalies followed by (14%) hypertensive disorder in pregnancy, intrapartum hypoxia (14%), unexplained causes (14%), 9.5% cord prolapse, antepartum haemorrhage (9.5%), 5% due to intrauterine growth restriction, gestational diabetes mellitus or preterm labour. Most of the mothers whose baby had perinatal deaths had ANC outside. Most of the deaths occurred in between gestational age of 37 to 41 weeks. Perinatal mortality was more in multigravida. Delay to seek health care and inadequate antenatal checkups were the most common avoidable factors.

Conclusions: Congenital anomalies and hypertensive disorders during pregnancy were the most common causes of perinatal death. Delay in health seeking behaviour was the most common avoidable factors for perinatal death. We recommend early identification of high risk pregnancy through proper antenatal screening, educating pregnant women to identify danger signs of pregnancy, creating public awareness about importance of antenatal checkups, vigilant labour monitoring for foetal distress, to reduce some categories of deaths.

Published: March 2019

Background: Globally, more than half of all TB cases are not detected. If they are not diagnosed and get treatment infection transmission may continue and patients suffer and may eventually die. Pulmonary TB either smear positive or negative is normally diagnosed by Ziehl-Neelsen stained sputum smear examination microscopy. Since the culture is the gold standard, evaluation of smear negative TB cases by this method is likely to detect more cases.

Objectives: The objective of this study is to find out culture positivity among smear negative patients.

Methods: All the three sputum samples reported negative by Ziehl-Neelsen microscopy from a total of 138 new TB suspected cases more than 15 years of age at NTC Laboratory. Nepal were cultured on Lowenstein-Jensen media. Tubes showing sufficient growth (culture positive) were recorded and all the culture positive results were informed to NTC. The culture positive samples were processed for DST on first line drugs using proportion method.

Results: The culture positivity rate was 5.1% (7 of 138 cases) All the positive cultures were processed for DST on first line anti-TB drugs and none showed resistance of the total 138 suspected Tuberculosis patients, 94 (68.1%) were males and 44 were females (31.9%) with male: female ratio 1:047. The mean age of the total patients were 30.69. Nearly 42% of them belonged to 31-50 years. Mean age of the male patients was significantly higher than total of the female (p<.001).

Conclusions: Seven smear negative cases among the total of 138 suspected TB patients attending NTC were culture positive. Similar study has to be done in other parts of the country.

With the identification of problems above, it can be concluded that SMK PGRI 1 requires an online-based learning media that can help teachers and students in the effectiveness of learning in SMK PGRI 1. Research methods used in this paper is the technique of data writing and system development model. Problems that exist in SMK PGRI 1 Jakarta among them is the absence of online learning media, teaching methods are still done directly in the classroom, Limited time of study in class so that materials that require discussion in a long time should be explained in a short time and if the teacher unable to attend for a reason it will result in delayed delivery of material that has been adjusted based on the curriculum, Lack of efficiency and practicality for students in obtaining material or collecting tasks. Because there are still many teachers in providing materials and gathering tasks conventionally or manually, so that felt inefficient in time and energy.
StressLifetc – NDT-related assessment of the fatigue life of metallic materials
Authors: Starke Peter
Published: March 2019

Weight-optimized component design as well as a reliable estimation of the lifetime of metallic materials and components requires a comprehensive understanding of fatigue processes and a systematic investigation of the underlying fatigue behavior. Therefore, nondestructive testing methods, digitalization of measurement techniques as well as signal processing can be combined with a short-term procedure in order to acquire potentially more information about fatigue processes, while experimental effort and costs are reduced significantly. This leads not only to considerable advantages over conventional methods for determining S-N curves, but also over established short-term procedures, due to the possibility of applying this information from just a few specimens to attain fatigue life calculations. The StressLifetc approach is a new short-term calculation method which considers the nonlinear relation between the elastic, elastic-plastic and plastic portion of the material response in the deformation process. Within the scope of the present work, the change in temperature of SAE 1045 (C45E) specimens was measured during fatigue tests via an infrared camera in order to feed the thermal response back into the new StressLifetc approach for a reliable fatigue life calculation.
Comparative study on fatigue behavior between unbonded prestressed and ordinary reinforced reactive powder concrete beams
Authors: Luo Xuguo , Tan Zhenglong , Chen Y. Frank , Wang Yixiang
Published: March 2019

Two types of reactive powder concrete beams, one with normal mild steel and another with unbonded prestressing tendons, were studied experimentally. Specifically, static load and constant amplitude fatigue tests were performed. The beam cracks, midspan deflections, and variations of extreme concrete and steel strains with fatigue loading cycles were compared. The fatigue test results show that fatigue life is more than 2 million cycles for both types of RPC beams within the usual low fatigue stress range (98 % probability of appearance). The crack width, maximum compressive strain, midspan deflection, and maximum tensile strain are 0.08 mm, 814 μξ, 7.6 mm, and 484 μξ, respectively for unbonded prestressed reactive powder concrete beams. They are 0.12 mm, 1147 μξ, 10.3 mm, and 1226 μξ, respectively for ordinary reinforced reactive powder concrete beams. All of these values obtained from the fatigue test are significantly below the corresponding failure values under the static test. The study results show that an unbonded prestressed reactive powder concrete beam has better fatigue performance than an ordinary reinforced reactive powder concrete beam.
Quantitative analysis of metal fiber morphology by level set image segmentation algorithms
Authors: Pan Minqiang , Dong Guanping , Zhong Yujian , Wang Hongqing , Zhou Xiaoyu
Published: March 2019

Due to their advantages of high porosity, large specific surface area, and abundant surface topography, porous fiber-sintered plates are widely used in microreactors. The fiber surface in the cutting process generates a rich micro-surface morphology which can effectively improve the catalyst load and promote reaction efficiency. There is currently a lack of quantitative analysis of the microchannel surface topography features. In this study, a new image segmentation technique based on level set algorithms was developed to study the microscopic features of the metal fibers processed under different processing parameters, allowing for the establishment of a matching relationship between the microscopic roughness of the fiber surface and the equivalent diameter of the fibers. The experimental results show that the surface topography characteristic coefficient (STCC) was approximately inversely proportional to the cutting speed (r × min−1), which was approximately proportional to the feed (mm × r−1). The cutting depth (mm) effect on the STCC value of the fibers was not obvious. At low speed, with a cutting speed n = 20 r × min−1, feed rate f = 0.08 mm × r−1, and cutting depth ap = 0.11 mm, the STCC of the metal fiber reached a maximum value of 115.927. At high speed, with a cutting speed of n = 400 r × min−1, feed rate f = 0.06 mm × r−1, and cutting depth ap = 0.17 mm, the metal fiber STCC reached a maximum of 128.605. The parameters corresponding to the maximum STCC value can be used as the optimal turning parameters of metal fiber material for making a porous fiber microchannel reactor.

Nanocomposites have attracted much attention from scientific and industrial areas in recent decades because of their mechanical, physical, thermal and barrier properties and unique design possibilities. These materials have been commercially used in the automotive, electronic, biomedical, packaging etc. industries and their usage areas have been increasing day by day. In this study, nanocomposite adhesives were produced by adding nano graphene and multi-walled carbon nanotube (MWCNT) particles to a single component epoxy adhesive at the ratios of 0.1, 0.2, 0.3, 0.4, 0.5, 0.7, 1, 3 and 5 wt.-%. Then, these nanocomposite adhesives were used to prepare single-lap joints. Shear tests were performed to specify their adhesive shear strengths and joint tensile strengths. It was observed that mechanical strength increased to the reinforcement amount of 0.5 wt.-%. After that, the strength values decreased due to a tendency towards agglomeration, viscosity increment and due to a difficulty in homogeneously applying the adhesive. Furthermore, it was found that nano graphene reinforcement improved the mechanical strength of the epoxy-based adhesive slightly more than MWCNT reinforcement.
Experimental study on gas emission from coal mass with a rich microstructure

Published: March 2019

Through a coal mass sample with a rich microstructure and a self-designed experiment using lump coal to determine the characteristics of gas emission, this paper analyzes gas emission in a coal mass with rich microstructure. The results show: The differences between raw coal and a briquette are mainly found in the scale and number of their microstructures. Nevertheless, the two samples share a high degree of similarity. The gas emission speed of a coal particle is higher than that of coal mass with a rich microstructure. The decay rate of gas emission speed also is confirmed as the same process. It takes longer for coal mass with a rich microstructure to reach the limit of its gas emission volume than for coal particles. Gas emission in a coal mass is a continuous process of gas desorption, migration and seepage. During the process, the coal mass reacts in four possible ways: coal mass immediately participating in gas emission, gradually participating in gas emission, providing a gas source for gas emission and as a non-affected coal mass. The relation between the gas emission speed of the coal mass with a rich microstructure and test time shows a monotone decrease in the power function, and the relation between the cumulative volume of the gas emission and the test time reveals a monotonically increasing logarithmic function. The gas emission for coal mass with a rich microstructure can be well expressed by modified logarithmics.

A novel approach has been successfully developed to synthesize Pd@Au core/shell nanosheets by using lemon extract as a biological reducing agent and microwave heating. This approach is suggested to be an eco-friendly, rapid and simple method for the synthesis of Pd@Au core/shell nanosheets. The Au shells that covered the Pd nanosheet surfaces were formed at 80 W in microwave for 20 min. The prepared Pd@Au core/shell nanosheets were characterized by UV–vis spectrophotometry, X-Ray diffraction, transmission electron microscopy, energy dispersive X-ray, energy dispersive X-ray elemental-mapping and energy dispersive X-ray line profile. A highly self-assemblage surface-enhanced Raman scattering methodology was developed by applying Pd@Au core/shell nanosheets for trace fluorescent dye detection. The highest R6G signal was attained with an Au layer of about 3 nm thickness. The results show that the SERS technique is able to detect trace fluorescent dye within a wide concentration range from 10−8 M to 10−17 M, with an extremely low limit of detection of 10−17 M. The study offers a low-cost route to the fabrication of sensing devices capable of use for monitoring cancer progression in natural matrices such as blood.

A novel method is presented for the synthesis of Ti2SC powder by heating FeS2/Ti/TiC mixtures. The phase evolution of Ti2SC was explored in detail with X-ray diffraction, thermo-gravimetry/differential scanning calorimetry, and scanning electron microscopy analysis. It was found that FeS2 began to decompose into activated FeS and released molecular state sulphur at around 500 °C. Subsequently, FeS and Ti underwent a reaction that formed Fe and TiS at 700 °C. Finally, the reaction of both TiS and TiC to form a Ti2SC phase could be triggered at 900 °C. It was confirmed that the Ti2SC phase was obtained with only trace impurity of TiC remaining after acid treatment by microwave hybrid heating of 1.1FeS2/2Ti/2TiC mixtures at 1 300 °C for 3 min. The fine powder with a mean diameter of approximately 1 μm was mainly composed of quasi-spherical particles. Compared to the conventional method, Ti2SC powder was synthesised at a temperature some 300 °C lower and required only 10 % of the heating time.
Innovation strategies in CKD prevention and treatment – challenges, opportunities and sharing best practice
Authors: Kolesnyk M.
Published: March 2019

Abstract. Chronic kidney disease (CKD) is a global public health problem, with cardiovascular disease being the major cause of mortality in these patients. CKD is associated with elevated risks of all-cause mortality and other adverse outcomes. This review is highlighting the consistency of the evidence about the hazards that are associated with CKD.

The challenge that clinicians now face is to search for CKD, to manage it aggressively, to evaluate novel means of detecting CKD and to expand the therapeutic strategies for patients with CKD. The evidence base for informing effective kidney care is limited, and the translation of existing knowledge to routine clinical care is slow.

Innovative approaches are described – patient-oriented care, complex care individualization, early screening for cognitive disorders, anxiety, renal education including education aids & e-Kidney application, teletechnology approach and CKD-self-testing in rural area, novel therapeutic targets for innovative CKD-oriented drugs, etc. Trials with the aim of re-purposing of generic therapeutics should be prioritized if sufficient scientific evidence is available. Furthermore, strategies used to extend patent life of drugs, but without investment to assess re-purposing, should be discouraged.

Finally, if the above goals are achieved, new therapies will certainly become available to stop, slow, or reverse CKD. These therapies should be made accessible to populations around the globe.

Abstract. The aim of the study was to assess a serum level of vascular endothelial growth factor (VEGF) in type 2 diabetic patients depending on kidney function.

Methods: we examined 66 type 2 diabetic patients and 20 healthy control subjects. Depending on the presence of albuminuria and glomerular filtration rate (GFR) level, patients with diabetes mellitus (DM) were divided into the following groups: group I - patients with type 2 DM without signs of nephropathy – normal GFR without albuminuria (n = 26); group ІІ - patients with type 2 DM with normal GFR and albuminuria (n = 22); group III - patients with type 2 DM with reduced GFR and albuminuria (n = 18). ІV group - patients with acute coronary syndrome (n = 26).

The concentration of the VEGF was determined by enzyme-linked immunosorbent assay. The glomerular filtration rate (GFR) was calculated using the CKD EPI formula (KDIGO 2012).

Results: serum VEGF level in patients with diabetic nephropathy (DN) was significantly increased depending on kidney function.

VEGF positively correlated with urine albumin and serum creatinine levels and the negative correlation with GFR was found. These findings prove the undeniable role of kidneys in the development of renocardial syndrome in patients with DN. VEGF levels positively correlated with glycosylated hemoglobin and total cholesterol, indicating an unconditional dependence of endothelial dysfunction on lipid and glucose metabolism disorders.

Conclusions: Increased levels of VEGF in type 2 diabetic patients without clinical signs of kidney damage may indicate the development of subclinical renal dysfunction. Blood VEGF in patients with DN may be an integral marker of endothelial dysfunction and pathological angiogenesis. Our findings suggest that determination of serum VEGF level in patients with DN may have practical use as an early predictor of cardiac disruption, estimation of the prognosis, as well as improvement of cardionephroprotective strategy.

Abstract. The formation in β-structured protein aggregates in tissues and fluids of the body is one of the most dangerouse complications of various diseases. The most famous of them are amyloidoses, but they such deposits are observed at other, much more widespread, diseases. The generally accepted approach to amyloids’detectionis based on  high-specific coloring by Congo Red dye. However, the Abbe's diffraction limit excludes the seeing of the objects smaller than 0.61 wavelengths (about 240 nm). Such nanoscale formations are capable to disrup the functioning of surrounding tissues, to causethe complications and recurrences of the disease, and to pass through biological barriers with the following accumulation in body’s fluids. It’s likely that these conditions are the cause of the urinary congophilia, that is associated with preeclampsia at pregnancy and chronic kidney disease. Nor the less suspicious object is the Bens-Jones protein that appears in the urine at multiple myeloma and some other diseases, which are in more or less extent,are related to the disturbance of protein metabolism.

The purpose of this study was to clarify the aggregate state of the Bens-Jones protein as a possible β-structured supramolecular associate.

Methods.The subject of the study was the freshly received urine from a patient with multiple myeloma. The presence of the Bens-Jones protein was checked by thermopacification of the acidified sample. For control, the urine was used by a healthy person with the addition of certain amounts of human serum albumin ("Reanal", Hungary) with a concentration of 0, 0.01, 0.1 and 1%.

Result. The obtained data testify to the appropriateness of such a point of view and create preresquites for the expanding of diagnostic possibilities.

Conclusions.The results obtained during the study testify to the peculiarity of the structure of the Bens-Jones protein, which is nano-sized beta-structured supramolecular
