İmmunoterapi ve Radyoterapi Kombinasyonu
Authors: SARIHAN Süreyya
Published: June 2020

İmmunoterapi, bağışıklık sisteminin güçlendirilmesi ile birçok kanser türünde yanıt, yanıt süresi ve sağkalım açısından etkinliği kanıtlanmış bir tedavidir. Yanıt oranları %20 olup dirençli hastalarda immunoterapi ile sinerjik etki yaratan yeni tedavilere gereksinim vardır. Radyoterapi ile tümör hücrelerinden salınan antijenik uyarı tümörün bağışıklık sistemi tarafından daha kolay tanınmasını sağlayarak immunoterapinin tamamlayıcısı olabilir. Radyoterapinin, ışınlanan hedef dışındaki metastazlar üzerindeki sistemik etkisi “abscopal” etki olarak tanımlanmış olup immuno-radyoterapinin temel amacı “abscopal” etkiyi uyandırmaktır. İmmuno-radyoterapinin yanıt ve sağkalıma anlamlı katkısı öncelikle malign melanom ve akciğer kanserlerinde gösterilmiş olup diğer solid tümörlerde de gelecek vaat eden önemli bir tedavi yöntemi olarak görülmektedir.
ПРАВОВІ АСПЕКТИ ПРОТИДІЇ УХИЛЕННЮ ВІД СПЛАТИ ВВІЗНОГО МИТА ТА АКЦИЗНОГО ПОДАТКУ ПІД ЧАС ВВЕЗЕННЯ НА ТЕРИТОРІЮ УКРАЇНИ НАФТОПРОДУКТІВ

Published: June 2020

В умовах критичної залежності вітчизняного ринку нафтопродуктів від постачань імпортного палива, зростання попиту та цін на ринку нафтопродуктів України питання удосконалення оподаткування імпортних операцій з вказаними товарами залишаються актуальними і потребують додаткового вивчення. Залежність від імпорту газу та нафти негативно впливає на стан вітчизняної економіки та несе загрозу енергетичній безпеці держави. Втрата діючих і перспективних родовищ видобутку вуглеводнів внаслідок анексії Криму і військових дій на Сході країни створюють нові ризики енергетичної безпеки країни. У статті розглядаються питання протидії ухиленню від сплати ввізного мита та акцизного податку під час ввезення на територію України нафтопродуктів. Розглянуті способи попередження порушень митного та податкового законодавства під час ввезення на митну територію України нафтопродуктів та товарів, що можуть використовуватись у разі незаконного виробництва автомобільного моторного палива. Наведено приклад вдалого регулювання ринку нафтопродуктів за рахунок розширення переліку підакцизних товарів. З метою дієвого регулювання ринку нафтопродуктів, спрямованого на зменшення обсягів «тіньових» операцій з пально-мастильними матеріалами, недопущення порушень митного та податкового законодавства під час ввезення та подальшої реалізації автомобільного палива та збільшення обсягів сплати податків від здійснення вказаної діяльності, автором пропонується створити робочу групу з числа представників профільних міністерств та служб (Міністерства економічного розвитку і торгівлі, Міністерства енергетики та вугільної промисловості, Міністерства фінансів України, Державної фіскальної служби та ін.) для встановлення переліку продуктів нафтохімічної і хімічної промисловості, які можуть використовуватись як сировина для виробництва автомобільного моторного палива. За результатами формування такого переліку розробити зміни до Податкового кодексу України у частині розширення переліку підакцизних товарів.

Published: June 2020

Current study was planned to find out the difference between the perceived parenting styles of drug addict and non-addict medical students. Total sample of the study was two hundred (N=200) medical students that comprised of one hundred addict (n=100) and one hundred (n=100) non-addict medical students with age range of 18 to 29 years. Data was collected from different medical colleges in Khyber Pakhtunkhwa through convenient and snow ball techniques. Data was collected through adolescent’s alcohol and drug usage scale (Moberg, 1991)and parenting styles questionnaire (Buri, 1991) . The results of the study indicated that authoritative parenting style was significantly reported by non-addict medical students, whereas addict medical students reported higher scores on authoritarian parenting style. It can be therefore concluded from the findings of the study that parenting styles play a significant role in the mental wellbeing and promotion of healthy habits among youth. The study supports the idea that controlling parenting style may contribute to promote mental health problems among youth such as drug addiction.

Published: June 2020

The Indonesian country which is famous for its tropical climate has now experienced a shift in two seasons (dry season and rainy season). This has an impact on cropping and harvesting systems among farmers. In large scale this is very influential considering that farmers in Indonesia are stilldependent on rainfall which results in soil moisture. Some types of plants that are very dependent on soil moisture will greatly require rainfall or water for growth and development. Through this research, researchers tried to make a prototype application for watering plants using ATMEGA328 microcontroller based soil moisture sensor. Development of application systems using the prototype method as a simple method which is the first step and can be developed again for large scale. The working principle of this prototype is simply that when soil moisture reaches a certainthreshold (above 56%) then the system will work by activating the watering system, if it is below 56% the system does not work or in other words soil moisture is considered sufficient for certain plant needs.

Development of High Yielding Deep Water Rice Variety BRRI dhan91 for Semi Deep Flooded Ecosystem of Bangladesh
Authors: Shalahuddin A K M , Masuduzzaman A S M , Ahmed M M Emam , Aditya T L , Kabir M S
Published: June 2020

Deep water rice ecosystem represents the flood-prone rice ecosystem where rice plant requires elongation ability to reach the surface with a certain amount of plant height to withstand in stagnant flood water condition. Low yield potentiality of locally adapted deep water cultivars limits the total rice production in the country. In present study, efforts were made to evaluate the suitability and adaptability of newly developed high yielding deep water breeding line BR10230-15-27-7B and control variety Fulkori under semi deep water ecosystem of farmer’s field condition in three consecutive years. At six locations, water depth varied from 60 to 140 cm under semi deep water ecosystem. In 2016 and 2017, mean yield of the line ranged between 2.9 to 3.1 t ha-1 while 1.7 t ha-1 for the local control variety Fulkori. However, around 1.0 t/ha yield advantage was found for the newly developed breeding line. Thus, the higher yield potentiality of the breeding line under 140 cm water depth conditions suggested its suitability under shallow flooded environments. During final evaluation in 2018, larger variation was observed in terms of grain yield ranging from 1.1 to 3.8 t ha-1 for the line while 0.4 to 1.7 t ha-1 for the control variety when evaluated under actual deep water areas. This result also supported that this line have greater potentiality under shallow flooded condition. In addition, the breeding line exhibited similar plant height with at least six days earliness compared to the control variety. Finally, National Seed Board (NSB) approved this line as variety and designated as BRRI dhan91 for broadcast Aman (B. Aman) season. In future, this new rice variety could help the local rice growers to cultivate modern high yielding rice variety in shallow flooded environments. BRRI dhan91 also showed better performance for tallness with lodging tolerance, submergence tolerance and moderate elongation ability under shallow flooded conditions.

Intuition and Excess: Mona Hatoum's Measures of Distance and the Saturated Phenomenon
Authors: Hezekiah Gabrielle A.
Published: June 2020

This article argues that Mona Hatoum's video Measures of Distance presents us with an example of Jean-Luc Marion's saturated phenomenon. Partial and deeply textured images of Hatoum's mother have prompted scholars to explore questions of absence, exile, intimacy and loss. In contrast, I focus on the presence of the mother and her manner of appearing. I suggest that Hatoum's mother appears through an excess of intuition, the video itself coming into our consciousness as a particular configuration of Marion's notion of givenness. In this phenomenological understanding, Hatoum's mother escapes objectification not merely because of the aesthetics of layering but because the scale of the givenness of her appearing exceeds any objective conception of it.
Results of electrometric assessment of quality of marginal fit of composite material to hard tissues of teeth in various clinical conditions
Authors: Iyashvili L. V. , Vinnichenko Yu. A. , Avraamova O. G.
Published: June 2020

The purpose of the study was a clinical electrometric assessment of the quality of the marginal fit of the composite material to the hard tissues of the tooth, depending on the type and amount of adhesive used the influence of the adhesive, namely: the mechanism of its action and quantity, on the quality of restoration of the hard tissues of the tooth lost by the carious process in the composite material over time.

Material and methods. In clinical conditions, 140 fillings were examined, the placement of which was carried out only in cavities of classes 1 and 2, with the area affected by the carious process of hard tooth tissues from 30 to 50 mm2. For this, composite material ESTET X and adhesive systems were used: one-component XP BOND and self-etching XENO V in different volumes (6.6 and 17.7 mg). To assess the marginal fit of the filling material to the hard tissues of the tooth, the multifunctional electro-diagnostic device EST-DENT (Geosoft, Russia) was used. The principle of operation of the device is based on measuring the strength of the current flowing through the hard tissues of the tooth under the influence of a low-voltage source of electrical power. 

Results. The quality of the marginal fit of composite fillings to the hard tissues of the tooth, which is the main factor determining the durability of their functioning, largely depends on the amount of adhesive used, its mechanism of action, the area and depth of the carious lesion of dentin. Over time, there is a change in the structure obtained as a result of the mechanical and chemical interaction of the adhesive system and hard tissues of the tooth (primarily the hybrid layer), in the direction of decreasing its density and breaking integrity. This in turn increases the amount of electric current passing through it.

Conclusions. An analysis of the obtained clinical data shows that when restoring hard tissues of teeth lost over large areas and located close to the pulp cavity of the coronal part of the tooth, it is necessary to take into account the effect of dentinal fluid on the quality and durability of the restoration. The use in these cases of adhesive systems in an amount of not less than 17.7 mg (a drop from dispenser), careful preparation of the affected tooth tissues, rational design of the formed cavity, strict adherence to the manufacturer’s recommendations on the time of use of the adhesive. can significantly reduce the risk of unsatisfactory treatment results.

Resonant Vessels in Russian Churches and Their Study in a Concert Hall
Authors: Kanev Nikolay
Published: June 2020

Resonant vessels in ancient and medieval buildings are the subject of some historical and acoustic research today. There have been a number of detailed surveys of European churches, where acoustic pots remain in the buildings. Despite the fact that in medieval Russia the use of built-in vessels was very common in the construction of churches, they have been hardly considered in recent publications. Therefore, the first goal of this paper is to give a brief overview of the Russian experience. Some of the most interesting examples of Russian churches are presented, and among them there may be a world record for the number of the vessels in a single room. The Church of St. Nicholas in Pskov has about 300 pots inserted into the walls, apse and pendentives. The second goal is to study the efficiency of acoustic vessels in an ordinary room. Acoustic measurements were carried out in the Rachmaninov Hall, which is part of the Moscow Conservatory. This chamber concert hall built over 100 years ago has 29 vessels. The first conclusion is that the vessels behave like resonators, their natural frequencies have been identified. The second conclusion is that we found no considerable changes of the acoustics due to the vessels.

Authors: Ribeiro Marta , Ellerbroek Joost , Hoekstra Jacco
Published: June 2020

Current investigations into urban aerial mobility, as well as the continuing growth of global air transportation, have renewed interest in Conflict Detection and Resolution (CD&R) methods. With the new applications of drones, and the implications of a profoundly different urban airspace, new demands are placed on such algorithms, further spurring new research. This paper presents a review of current CR methods for both manned and unmanned aviation. It presents a taxonomy that categorises algorithms in terms of their approach to avoidance planning, surveillance, control, trajectory propagation, predictability assumption, resolution manoeuvre, multi-actor conflict resolution, considered obstacle types, optimization, and method category. More than a hundred CR methods were considered, showing how most work on a tactical, distributed framework. To enable a reliable comparison between methods, this paper argues that an open and ideally common simulation platform, common test scenarios, and common metrics are required. This paper presents an overview of four CR algorithms, each representing a commonly used CR algorithm category. Both manned and unmanned scenarios were tested, through fast-time simulations on an open-source airspace simulation platform.
Effect of Planting Methods and Gypsum Application on Yield and Water Productivity of Wheat under Salinity Conditions in North Nile Delta
Authors: Aboelsoud Hesham , Engel Bernard , Gad Khaled
Published: June 2020

Salinity and water shortage are the most important factors limiting crop productivity, so increasing the productivity of salt-affected soils is important to address the global food gap. Two field experiments were conducted under typical farm conditions in the North Nile Delta to study the effect of planting methods and gypsum application on wheat yield and water productivity under a range of water and soil salinity levels. In the first experiment, wheat was treated with gypsum (25%, 75%, and 100% gypsum-requirement) with moderate or high salinity in soil and water. The second experiment was conducted for two seasons at two sites to test three planting methods (flat, 60-cm furrows, and 120-cm raised-beds) under normal or high salinity levels of both soil and water. The results showed that gypsum alleviated the hazardous effects of salinity stress on grain yield. Raised furrows or beds under higher salinity levels increased soil salinity, and soil salinity was slightly increased with flat plots. Higher yields, water savings, and water productivities were achieved with raised furrows or beds under normal salinity. To improve yield under normal salinity conditions, raised beds are the recommended planting method. Furthermore, gypsum application in cultivated fields can mitigate the negative effects of salinity stress.

Organic waste such as food waste and livestock manure is a serious concern in the Pacific Islands, where landfills are overflowing and illegal dumping of waste threatens the fragile ecosystems. Organic waste also attracts filth flies, some of which are vectors for pathogens that cause human disease. The black soldier fly, Hermetia illucens, has tremendous potential for the Pacific Islands. Capable of digesting almost any organic matter and converting it into insect biomass, black soldier flies are already being used around the world to process organic waste into larvae. The system can be adapted to large-scale municipal composting as well as small sizes for individual livestock farms or even urban households. The larvae can be fed live to fish or poultry, processed into feed comparable to fishmeal or soy meal, or even used to generate biofuel. Thus, the fly not only eliminates waste, but also can improve the sustainability of livestock production. The Pacific Small Island Developing States stand to benefit immensely from black soldier fly bioconversion facilities, used primarily as a means to compost organic waste; however, several knowledge gaps must first be addressed. We reviewed the state of black soldier flies in the Pacific and identified where their use shows the most promise. Research priorities for the field include fly surveys and bioconversion assays using Pacific crop waste.

Objectives: Chromosomally mediated AmpC-producing Enterobacteriaceae (CAE) display high susceptibility to fluoroquinolones; minimal clinical data exist supporting comparative clinical outcomes. The objective of this study was to compare treatment outcomes between fluoroquinolone and nonfluoroquinolone definitive therapy of bloodstream infections caused by CAE. Methods: This retrospective cohort assessed adult patients with positive blood cultures for CAE that received inpatient treatment for ≥48 h. The primary outcome was difference in clinical failure between patients who received fluoroquinolone (FQ) versus non-FQ treatment. Secondary endpoints included microbiological cure, infection-related length of stay, 90-day readmission, and all-cause inpatient mortality. Results: 56 patients were included in the study (31 (55%) received a FQ as definitive therapy; 25 (45%) received non-FQ). All non-FQ patients received a beta-lactam (BL). Clinical failure occurred in 10 (18%) patients, with 4 (13%) in the FQ group and 6 (24%) in the BL group (p = 0.315). Microbiological cure occurred in 55 (98%) patients. Median infection-related length of stay was 10 (6–20) days, with a significantly longer stay occurring in the BL group (p = 0.002). There was no statistical difference in 90-day readmissions between groups (7% FQ vs. 17% BL; p = 0.387); one patient expired. Conclusion: These results suggest that fluoroquinolones do not adversely impact clinical outcomes in patients with CAE. When alternatives to beta-lactam therapy are needed, fluoroquinolones may provide an effective option.

Golden root (Rhodiola rosea L., Crassulaceae) is a famous medical plant with a one-sided history of scientific interest in the roots and rhizomes as sources of bioactive compounds, unlike the herb, which has not been studied extensively. To address this deficiency, we used high-performance liquid chromatography with diode array and electrospray triple quadrupole mass detection for comparative qualitative and quantitative analysis of the metabolic profiles of Rhodiola rosea organs before and after gastrointestinal digestion in simulated conditions together with various biochemical assays to determine antioxidant properties of the extracts and selected compounds. R. rosea organs showed 146 compounds, including galloyl O-glucosides, catechins, procyanidins, simple phenolics, phenethyl alcohol derivatives, (hydroxy)cinnamates, hydroxynitrile glucosides, monoterpene O-glucosides, and flavonol O-glycosides, most of them for the first time in the species. The organ-specific distribution of compounds found for catechins, procyanidins, and cinnamyl alcohols and glucosides was typical for underground organs and flavonoids and galloylated glucoses concentrated in the herb. Extracts from rhizomes, leaves and flowers showed high phenolic content and were effective scavengers of free radicals (2,2-diphenyl-1-picrylhydrazyl (DPPH•), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+), O2•−, •OH) and protected β-carotene in a bleaching assay. Digestion in the gastric and intestine phase influenced the composition of R. rosea extracts negatively, affecting the content of catechins, procyanidins, and galloyl glucoses, and therefore, the antioxidativity level. After gut microbiota treatment, the antioxidant capacity of rhizome extract was lower than leaves and flowers due to the aglycone composition found in the colonic phase of digestion. Our study demonstrated that the herb of R. rosea is a rich source of metabolites with high antioxidant properties and could be a valuable plant for new bioactive products.

Carotenoids are well known for their potent antioxidant function in the cellular system. However, in cancer cells with an innately high level of intracellular reactive oxygen species (ROS), carotenoids may act as potent pro-oxidant molecules and trigger ROS-mediated apoptosis. In recent years, the pro-oxidant function of several common dietary carotenoids, including astaxanthin, β-carotene, fucoxanthin, and lycopene, has been investigated for their effective killing effects on various cancer cell lines. Besides, when carotenoids are delivered with ROS-inducing cytotoxic drugs (e.g., anthracyclines), they can minimize the adverse effects of these drugs on normal cells by acting as antioxidants without interfering with their cytotoxic effects on cancer cells as pro-oxidants. These dynamic actions of carotenoids can optimize oxidative stress in normal cells while enhancing oxidative stress in cancer cells. This review discusses possible mechanisms of carotenoid-triggered ROS production in cancer cells, the activation of pro-apoptotic signaling by ROS, and apoptotic cell death. Moreover, synergistic actions of carotenoids with ROS-inducing anti-cancer drugs are discussed, and research gaps are suggested.

Constituents of liquid smoke possess a huge potential to be converted as value-added chemicals, such as flavoring, antiseptics, antioxidants, or even fossil oil substitutes. However, liquid smoke instability, led by the presence of oxygenate compounds, is an obstacle for further utilization and processing. On the other hand, catalyst efficiency in hydrodeoxygenation (HDO) remains challenging. Sarulla natural zeolite (Z), with abundant availability, has not been comprehensively investigated in the catalytic performance of HDO. In this study, Sarulla natural zeolite with different Si/Al ratios, which are activated by several concentrations of hydrochloric acid and nickel supported by Z (Ni-Z) synthesized by wet impregnation, were evaluated for HDO of liquid smoke, particularly in reducing oxygenate compounds. Catalyst morphology, surface area, pores, and crystallinity are investigated. Catalytic performances were evaluated, particularly on reducing oxygenate compounds and the shifting of phenol and its derivatives. Furthermore, the liquid smoke product of HDO was analyzed by gas chromatography-mass spectrometry (GC-MS). The data obtained reveal that the HDO process of liquid smoke with the Z3 catalyst shows the best activity compared to Z5 and Z7, with phenol conversion of 62.39% and 11.93% of alkoxy reduction. Meanwhile, the best Ni metal catalyst system activity was given by the Ni-Z5 catalyst compared to Ni-Z3 and Ni-Z7, where phenol conversion and alkoxy reduction were at 60.06% and 11.49%, respectively.

Published: June 2020

In order to solve the problems in the accuracy and adaptability of the existing methods for blade twist measurement, a high-precision and form-free metrological method of blade twist based on the parameter evaluation of twist angular position and twist angle is proposed in the study, and the theoretical model, the measurement principle and the key technologies of the method are discussed in detail. Three key issues of the twist metrology of a blade are solved based on technologies of calibration, a priori planning and geometric analysis: aeroengine axis matching, high-precision coordinate acquisition of the leading edge and the trailing edge, and extraction of twist angular position of the profile. The measurement path planning, sampling strategy optimization and high-precision coordinate collection are executed automatically without theoretical model data of the measured blade, thus the form-free and high-precision metrology of the blade twist is achieved. The research results show that the metrological method of blade twist presented in this study is effective, and that its measurement uncertainty is less than 0.01°. This method is form-free, efficient and accurate, and can solve the problems of high-precision measurement and evaluation for the twist of aeroengine blade primely.

The paper presents the results of influence the light of different wavelengths and pulsed electric fields on the content of carotenoids. Seeds germination was carried out in a climatic chamber with phytotron system. The experiment was carried out under seven growing conditions differing in light-emitting diode (LED) wavelengths and using pulsed electric fields (PEFs) with different strength applied before sowing. Cultivation of the sprouts was carried out for seven days at relative humidity 80% and 20 ± 1 °C. Different light wavelengths were used during cultivation: white light (380–780 nm), UVA (340 nm), blue (440 nm), and red (630 nm). In addition, the pulsed electric field (PEF) with three values of strength equal to 1, 2.5 and 5 kV/cm, respectively, was applied to three series of sprouts before sowing. Sprouts treated with the PEF were grown under white light (380–780 nm). The light exposure time for all experimental series of sprouts was 12/12 h (12 h light, 12 h dark for seven days). Lutein is the dominant carotenoid in germinating red clover seeds, the content of which varies from 743 mg/kg in sprouts grown in red light, 862 mg/kg in sprouts grown in UVA, to 888 mg/kg in sprouts grown in blue light. Blue light in the cultivation of red clover sprouts had the most beneficial effect on the increase of carotenoids content and amounted to 42% in β-carotene, 19% in lutein, and 14% in zeaxanthin. It confirms that modelling the content of carotenoids is possible using UVA and blue light (440 nm) during seed cultivation. An increase in the content of β-carotene and lutein in red clover sprouts was obtained in comparison to the test with white light without PEF pre-treatment, respectively by 8.5% and 6%. At the same time a 3.3% decrease in the content of zeaxanthin was observed. Therefore, it can be concluded that PEF pre-treatment may increase mainly the content of β-carotene.
