Authors: Vorobyov N. A. , Martynova N. I. , Mikhailov A. V. , Gutsalo Yu. V. , Kubasov A. V.
Published: July 2018

Background. In the last decade, we observed a significant increase in the number of patients undergoing radiotherapy for prostate cancer (PC). It became possible with the development of new equipment that can significantly increase radiation efficiency and reduce the frequency and severity of side effects. Active investigation of new fractionation regimens led to the development of stereotactic radiotherapy (StR) technique. In this article, we describe our own experience of using StR in patients with localized PC.

Material and methods. The study included 48 patients treated with CyberKnife robotic radiosurgery system. The patients received a total dose of 36.25 Gy delivered in 5 fractions.

Results. At a median follow-up of 24 months, the estimated four-year prostate-specific antigen (PSA) relapse-free survival rate was 95.8 %. The median PSA nadir was 0.48 ng/mL. We observed no grade III–IV side effects (either early or late).

Conclusion. Our results suggest that the use of StR allows achieving good biochemical control comparable to that achieved by other methods and demonstrates comparable and sometimes even lower toxicity.

Objective: to develop an effective and safe surgical technique for the treatment of patients with renal cell carcinoma with invasive tumor venous thrombosis of the inferior vena cava (IVC).

Materials and methods. The study included 75 patients underwent surgical treatment at the N.N. Blokhin Russian Cancer Research Center between 1995 and 2017. The median age of patients was 57 years (range: 32–72 years). All patients were diagnosed with RCC with invasive tumor venous thrombosis levels II–IV; of them, 55 patients (73.3 %) had complete IVC obstruction and mature venous collaterals. Twenty- seven patients (26.0 %) were diagnosed with regional, 37 (49.3 %) – with distant metastases. Prior nephrectomy was performed in 5 (6.7 %) cases. Surgical treatment included nephrectomy (n = 70; 93.3 %), thrombectomy with IVC resection (n = 75; 100 %), and metastasectomy in solitary distant lesions (n = 11; 14.7 %). Partial IVC resection was demanded in 18 patients (24.0 %): with infrarenal IVC plication – 14 (18.7 %), with reconstruction of IVC with synthetic patch – 4 (5.3 %). Fifty-seven patients (76.0 %) underwent circular IVC resection (with left renal vein (LRV) ligation – 35 (46.7 %)). The IVC was replaced with ePTFE grafts in 4 (5.3 %) patients, IVC reconstruction was not required in 53 (70.7 %) patients. IVC grafting was considered to be justified in patients without mature venous collaterals. Twenty-two patients (29.3 %) received systemic antitumor therapy. Median follow-up was 32.3 months (range: 1–226 months).

Results. Median operative time was 237.5 min (range: 135–580 min); median blood loss – 7000 mL (range: 1200–27 000 mL). The post- operative complications rate was 52.1 % (grades III–V – 31.5 %). Hospital mortality was 13.3 % (10 of 75 patients). Thirty-two months overall, cancer-specific, and recurrence-free survival were 42.4 %, 49.5 %, and 61.2 % respectively. At 19 months all prosthesis were patent. None of the patients had glomerular filtration rate <60 ml/min/1.73 m2 after LRV ligation. No patients developed disabling chronic venous insufficiency of the lower limbs after IVC ligation/resection without grafting.

Conclusion. Nephrectomy, thrombectomy, and IVC resection is the only effective method of treatment for RCC with invasive tumor venous thrombosis. The development of IVC and LRV venous collaterals allows performing circular IVC resection with LRV ligation without graft replacement.

Kidney cancer is a heterogeneous group of malignant tumors that develop from cells of the proximal convoluted tubules of the kidney. In Russia renal cell carcinoma holds the 2nd place after prostate cancer among tumors of genitourinary system. The main method of renal cell carcinoma treatment is radical nephrectomy, at the same time, high resistance of kidney cancer to chemotherapy and a weak response to hormone treatment are noted, and the effectiveness of cytokine therapy (interleukin 2, interferon alfa) does not exceed 18–20 %. The introduction into clinical practice of modern immune system affecting drugs has changed the disease prognosis for many patients with various malignant neoplasms. Currently, active development of immunotherapeutic drugs directed against inhibitory receptors of T-cells, the so-called “immunity control points” takes place, the most studied among these drugs are anti-CTLA-4 (cytotoxic T-lymphocyte associated protein 4) and anti-PD-1 (рrogrammed cell death pathway 1)/PD-L1 (programmed death ligand 1) monoclonal antibodies. In this review a detailed description of the PD-1 receptor and its PD-L1 ligand, as well as the prognostic and predictive significance of their expression in various types of renal cell carcinoma and the role in suppressing the antitumor T-cell immune response are presented. Blockade of PD-1/PD-L1 enhances antitumor immunity reducing the amount and/or immunosuppressive activity of regulatory T-cells (suppressors) and restoring the activity of effector T-cells that leads to an enhancement of the antitumor immune response. The blockade of PD-1 also stimulates proliferation of memory B-cells. In this regard, drugs that suppress the function of PD-1 are now widely used in the treatment of cancer including kidney cancer. The authors provide a list of promising drugs acting on PD-1/PD-L1 system used in renal cell carcinoma: nivolumab, pembrolizumab and some others. The results of clinical studies se of immunotherapeutic drugs in kidney cancer are analyzed.

Published: July 2018

The review is devoted to loop-mediated isothermal amplification (LAMP) – a novel molecular diagnostic method that has recently become increasingly popular. Unlike polymerase chain reaction, LAMP does not require thermal cycling; DNA or RNA amplification occurs at a constant temperature (about 65 °C) with 4 or 6 primers. This is a fast, highly-sensitive, and highly specific method, which does not require expensive equipment, where visual detection of the reaction products is performed by the unaided eye. LAMP is successfully used for the diagnosis of multiple viruses, bacteria, and other pathogens (including those in food). Moreover, it can be applied for the detection of singlenucleotide polymorphisms. Recently, a modified LAMP assay – one-step nucleic acid amplification (OSNA) – was validated for metastasis detection. OSNA was demonstrated to have almost the same sensitivity and specificity as standard diagnostic methods (sometimes even higher). Particular attention is paid to the mechanism of LAMP, primer design, and diagnostics of cancer using OSNA.

Phylloid (leaf-shaped) breast tumors are a rare disease and constitute 0.3–0.5% of all breast tumors. Due to the rare frequency of occurrence, as well as the small number of randomized studies that have been conducted on this pathology, there is currently no standardized approach to the diagnosis and treatment of phylloid tumors. The reports about these rare cases appearing in the literature are, as a rule, descriptive, which only emphasizes the difficulty of differential diagnosis, the development of the correct tactics for treating such patients. In connection with the rarity, it is very difficult to diagnose correctly this pathology, which requires a highly qualified doctor as a diagnostician in the initial contact with such a patient, and a pathologist doctor who establishes the final morphological diagnosis. Often, leaf-shaped tumors are mistaken for mammary fibroadenomas. Such difficulties in correct diagnosis in the preoperative period can lead to errors in the planning of treatment. Also, the recommendations for the treatment of patients with this diagnosis are not fully understood, since up to now there are no accepted treatment standards in both Russian and foreign recommendations. Due to the fact that this pathology of mammary glands is rare, the principles of treatment are based on small retrospective studies and clinical observations. In this review, we will discuss the results of major retrospective studies, including data on epidemiology, etiology, diagnostic approach, strategies and results of treatment of this complex group of breast pathologies.

Authors: Abdrakhimov V.Z.
Published: July 2018

It is shown that at present the current system of environmental regulation in Russia is divorced from the real context in which to exist. One of the most promising areas for the use of waste production is ─ involving them recycled as secondary material or energy resources. On the basis of waste oil shale obtained heat-insulating materials with high physical-mechanical indicators. Due to the involvement of industrial waste in manufacturing of heat-insulating materials may dramatically change the parameters of the raw material base of Russia, which also contributes to reducing environmental impact in the regions. The use of waste fuel and energy complex: inter-shale clay and slate slag in the production of insulating materials contributes to recycling of industrial waste, the protection of the environment and expansion of raw materials base for production of ceramic building materials. The compositions of the developed compositions, proposed to obtain a lightweight brick and a porous filler, the authors of this article obtained three patents of the Russian Federation. Utilization of industrial wastes contributes to the development of "green" economy.

The formulation of multicomponent binders and concretes based on fine-dispersed ash microspheres and enriched artificial aggregates promoted recycling of secondary raw materials and improvement of the ecological situation in the region.
In-Lecture Media Use and Academic Performance: Investigating Demographic and Intentional Moderators
Authors: Parry Douglas A. , Le Roux Daniel B.
Published: July 2018

The growing prevalence of continuous media use among university students in lecture environments has potential for detrimental effects. In this study we investigate the relationships between in-lecture media use and academic performance. Previous studies have shown that students frequently engage with digital media whilst in university lectures. Moreover, multitasking imposes cognitive costs detrimental to learning and task execution. We propose, accordingly, that the constant distractions created by digital media, interrupt the thought and communication processes of students during lectures and, subsequently, obstruct their ability to learn. To test this proposition we conducted a survey-based empirical investigation of digital media use and academic performance among undergraduate university students. A significant negative correlation was found between the number of in-lecture media use instances and academic performance. Furthermore, this effect was found to be pervasive independent of individual demographic factors and the intention with which a medium was used.
A Digital Forensic Readiness Architecture for Online Examinations
Authors: Kigwana Ivans , Venter H. S
Published: July 2018

Some institutions provide online courses to students to ease the courses’ workload. Online courses can also be convenient because the online course content management software conducts marking of tests and examinations. However, a few students could be willing to exploit such a system’s weaknesses in a bid to cheat in online examinations because invigilators are absent. Proactive measures are needed and measures have to be implemented in order to thwart unacceptable behaviour in situations where there is little control of students’ conduct. Digital Forensic Readiness (DFR) employs a proactive approach for an organisation to be forensically prepared for situations where there is little control over people. This can be achieved by gathering, storing and handling incident response data, with the aim of reducing the time and cost that would otherwise be spent in a post-event response process. The problem this paper addresses is that, at the time of writing this paper, there existed no known DFR architecture that can be used to collect relevant information for DFR purposes, specifically in the course of an online examination, as described in the standard published by the International Standards Organisation (ISO) and the International Electrotechnical Commission (IEC) (ISO/IEC 27043:2015) for incident investigation principles and processes. Due to the lack of DFR architecture, the authors propose an Online Examination Digital Forensic Readiness Architecture (OEDFRA) that can be used to achieve DFR when online examinations are conducted. This architecture employs already existing DFR techniques, discussed in the study, to help educational institutions achieve DFR in online examinations. This architecture, (OEDFRA), when implemented, will be tested in future research in order to confirm its contribution to the field of DFR.

Published: July 2018

Usability of software is a crucial aspect of successful applications and could give one application a competitive edge over another. Eye tracking is a popular approach to usability evaluation, but is time consuming and requires expert analysis. This paper proposes a semi-automated process for identifying usability problems in applications with a task-based focus, such as business applications, without the need for expert analysis. The approach is demonstrated on the eye tracking data from a mobile procurement application involving 33 participants. With the recent inclusion of built-in eye tracking hardware in mobile devices, the proposed approach introduces the possibility of conducting remote, large-scale usability studies for improving user experience in mobile applications.

Published: July 2018

Quantitative structure-activity relationship and molecular docking studies of 35 compounds of Biscoumarins and Biscoumarins thiourea derivatives as alfa-glucosidase inhibitors was performed. Density Functional Theory (DFT) method was employed for complete geometry optimization of the alfa-glucosidase inhibitors. Genetic Function Algorithm (GFA) of the material studio was utilized to develop four models. Model 1 was found to be the best model with R2 = 0.914362, R2 adj = 0.892953, Q2cv = 0.858197 and R2 pred = 0.614745. The proposed model is robustness and predicted with good internal and external validation. The descriptors should be considered when improving the inhibitory activities of biscoumarin derivatives against alfa-glucosidase. The docking results showed that ligands having Ortho substituted phenyl ring have good interactions with active site residues and good inhibitory activities as compared to ligands having either Para or Meta substituted phenyl ring except ligand 16 which has the highest docking scores of -12.5 kcal/mol but undergoes para substitution on the phenyl ring and formed hydrogen bond, hydrophobic and electrostatic interactions with the active residues of the enzyme. The QSAR model and molecular docking results agree with each other and give way to the designing of new inhibitors with better activity against alfa-glucosidase.

Authors: Bikbaev Rashid G. , Vetrov Stepan Ya. , Timofeev Ivan V.
Published: July 2018

The spectral properties of a one-dimensional photonic crystal bounded by a resonant absorbing nanocomposite layer with the near-zero permittivity have been studied. The problem of calculating the transmittance, reflectance, and absorptance spectra of such structures at the normal and oblique incidence of light has been solved. It is shown that, depending on the permittivity sign near zero, the nanocomposite is characterized by either metallic or dielectric properties. For the first time, the possibility of simultaneous formation of the Tamm plasmon polariton at the photonic crystal/metallic nanocomposite interface and the localized state similar to the defect mode with the field intensity maximum inside the dielectric nanocomposite layer is demonstrated. Specific features of field localization at the Tamm plasmon polariton and defect mode frequencies are analyzed.

The genetic diversity and relationships among eight species of Channa were investigated using amplified fragment length polymorphism (AFLP)-capillary electrophoresis. Ten EcoR I/Mse I primer pairs were selected out of thirty eight and were used for further AFLP analysis. The total amplified bands, consistency of bands and polymorphic bands ranged from 114 to 206, from 0 to 12 and from 114 to 196, respectively, with corresponding averages of 156.2; 4 and 152.2 respectively. The proportion of polymorphic bands ranged from 93.62 to 100%, with an average of 97.44%. The similarity coefficients among eight Channa species ranged from 0.5365 to 0.7875. The dendrogram generated after unweighted pair-group method with arithmetic means (UPGMA) clustering with NTSYS software indicated that the eight Channa species could be divided into four major clusters according to the genetic similarity coefficient of 0.58. Channa striata and Channa micropeltes were clustered into a separate branch that was far from the other six species and Channa argus kimurai (Shih) was closest to Channa argus. These results could be useful for conservation as well as for guiding research on captive breeding of Channa species.

The largehead ribbonfish, Trichiurus lepturus Linnaeus, 1758 forms a major fishery along north-west coast of India comprising the two coastal states of Gujarat and Maharashtra. Diet composition was analysed for five years (2010-2014) to understand shifts if any in the prey items. Seasonal changes in the prey items were studied for three years (2012-2014) to explore the temporal dynamics of prey availability in the ecosystem and in largehead ribbonfish guts. Feeding indices viz., Stomach fullness index (SFI), empty stomach ratio (ESR), gastrosomatic index (GaSI) and relative gut length (RLG) explained the feeding behaviour, seasonal dynamics and ontogenetic shifts in prey items. The Vacuity Index (VI) was estimated as 37.56%, indicating that T. lepturus is a carnivore and relatively edacious. Diet of T. lepturus comprised of fishes (47.16%), crustaceans (45.22%), molluscs (4.33%) and miscellaneous items (3.28%). Acetes sp. was the most dominant prey item during the study period. Feeding intensity was found to be high during the post-monsoon months which coincided with the period of gonadal maturation of the fish. Significant variations (p<0.05) were seen in the feeding indices during different months, different sizes and between sexes due to the availability of prey items, physiological changes and ontogenetic shifts. A detailed knowledge on diet composition, temporal dynamics in diet patterns and feeding indices can reveal the trophic interaction of prey-predator, resource abundance and fluctuations which are important inputs in
ecology-based fishery management models/tools.

Published: July 2018

The state of Bihar in India has a huge potential in fisheries and the research institutes of Indian Council for Agricultural Research (ICAR) are involved in building capacity of the fish farmers of the state. Since 2012-13 to 2014-15 about 1279 fish farmers from 21 districts of Bihar State were trained under the Department of Fisheries/Agricultural Technology Management Agency schemes by ICAR-Central Inland Fisheries Research Institute on inland fisheries management. An ex-post facto study was undertaken to measure the effectiveness of these training programmes. Data were collected from 400 trainees from six different districts of Bihar using a semi-structured interview schedule. The Training Effectiveness Index (TEI) was developed and the results of the study indicated that the logistic regression analysis with socio-economic variables like main occupation, land holding, membership in organisations had positive and significant effect on training effectiveness. The overall effectiveness of training was found to be 87.86% which was recorded under the high effectiveness category. The results also revealed that 44.8% of the trainees were young and they also had positive effect on training effectiveness. About 53% of the farmers perceived that the training situation provided to them was highly satisfactory. The farmers also perceived that these trainings helped them to increase their knowledge and skill, enhance entrepreneurial ability and also motivated them to initiate new enterprises.

Published: July 2018

Sargassum fusiforme (Harvey) Setchell (Sargassaceae, Phaeophyta) is an ecologically and economically important kelp species in East Asia. Restoration and responsible utilisation of S. fusiforme would be facilitated by the availability of an appropriate set of molecular markers. In the present study, we developed 16 microsatellite markers for S. fusiforme. A total of 99 different alleles were observed at the 16 microsatellite loci across 50 individual samples. The number of alleles per locus ranged from 4 to 10, with an average of 6.2 per locus. The observed and  xpected heterozygosities ranged from 0.483 to 0.833 and from 0.513 to 0.840, respectively. Only three of the loci deviated significantly from Hardy-Weinberg equilibrium after Bonferroni correction. No significant linkage disequilibrium was detected among the microsatellite loci. The obtained microsatellite markers will facilitate related research on S. fusiforme, such as ecological studies and genetic diversity assessments.

The hilsa shad Tenualosa ilisha (Hamilton, 1822), is a commercially important and highly relished food fish. This paper presents the length-weight relationships (LWR) and condition factor of hilsa, throughout its geographical distribution in India. A total of 910 samples of T. ilisha, comprising 404 males and 288 females collected from various locations of east and west coasts of India were used for analyses. Heterogeneity in the LWR of males, females and pooled population was noticed. The regression coefficient (b) ranged from 2.07-3.68 for pooled, 0.75-3.03 for males and 1.78-2.97 for females. The coefficient of determination (R2) varied between 0.72-0.98 in pooled, 0.73-0.94 in males and 0.76-0.97 in females. Fulton’s condition factor (K) ranged from 0.47-3.05 in pooled, 0.47-1.63 in male and from 0.77-3.05 in female samples whereas relative condition factor (Kn) varied from 0.48-2.51 in pooled population, from 0.47-1.56 in males and 0.76-2.33 in females. Mean Fulton’s condition factor (K) ranged from 0.7-1.33 in pooled population, 0.92-1.28 in males and from 0.95-1.39 in females whereas the mean relative condition factor (Kn) varied between 0.98-1.04 in pooled population, 0.98-1.04 in males and 0.98-1.03 in females. These parameters (b, K, Kn) have been found useful in evaluating the well-being of different populations of this species. Most of the populations under study showed concordance to ideal value of b, thereby indicating isometric growth. However, significant negative allometric growth was observed for pooled samples from Padma, Hoogly and males from Padma and significant positive allometric growth was observed in the pooled samples collected from Hoogly. Comparative study of recent data with the decadal old data (1999-2000) revealed differences in mean size of the fish. This study also indicates overexploitation of the species in the recent years, which might be due to intensive fishing efforts.

The fishery and stock status of cuttlefishes along the northern coast of Andhra Pradesh was studied with special reference to the needle cuttlefish; Sepia aculeata Van Hasselt, 1835. Cuttlefishes caught by trawlers along the coast of Andhra Pradesh contributed 68.29% of the total cephalopod landings of the state during the study period (2006-2016). The average annual cephalopod landing in Andhra Pradesh for the study period was 2991 t and the mean annual catch per hour (CPH) during 2006-2016 was 0.47 kg h-1. The cumulative sum (CUSUM) analysis indicated increasing trend in cuttlefish landings of the state during the study period. Stock status plots indicates that cuttlefish stocks along the Andhra Pradesh coast are in the “fully exploited” phase.

Published: July 2018

Longtail tuna Thunnus tonggol (Bleeker, 1851) is the major tuna resource in the neritic realms of the northern Arabian Sea and forms considerable fishery in the coastal nations in the region. Gujarat, on the north-west coast is the major province landing longtail tuna in India. The paper attempts to add to the hitherto sparse knowledge base on biology of the longtail tuna fished along the north-west coast of India, through a study spanning from 2011 to 2015. Reproductive biology, spawning, food and feeding dynamisms of the species were investigated. Sex ratio of the species was estimated as 1:2.1 and depicted an increase in male preponderance as the size increased. The fish attains maturity at 607 mm and it spawns during summer months starting from May. The fish is typically a non-selective feeder and over 22 taxa comprising of fishes, cephalopods and crustaceans formed the diet at varying rates over the year. Variation in feeding intensity at different reproductive stages is discussed besides the constraint posed by the large presence of unidentifiable, partially digested gut content.

Published: July 2018

This study aims to
predict the final exam scores and pass/fail rates of the students taking the
Basic Information Technologies – 1 (BIL101U) course in 2014-2015 and 2015-2016
academic years in the Open Education System of Anadolu University, through
Artificial Neural Networks (ANN). In this research, data about the demographics,
educational background, BIL101U course mid-term, final and success scores of
626,478 students was collected and purged. Data of 195,584 students, obtained
after this process was analysed through Multilayer Perception (MLP) and Radial
Basis Function (RBF) models. Sixteen different networks attained through the
combination of ANN parameters were used to predict the final exam scores and
pass/fail rates of the students. As a result of the analyses, it was found out
that networks established through MLPs make more exact predictions. In the
prediction of the final exam scores, it was determined that there is a low
level of correlation between the actual scores and predicted scores. In the
analyses for the prediction of pass/fail rates of the students, networks
established through MLPs ensured more exact prediction results. Moreover, it
was determined that the variables as mid-term exam scores, university entrance
scores and secondary school graduation year were of highest importance in
explaining the final exam scores and pass/fail rates of the students. It was
found out that in the higher institutions serving for Open and Distance
Learning, pass/fail state of the students can be predicted through ANN under
favour of variables of students which have been found as most the important
predictors.
