Screening Expectation
Authors: Bergen-Aurand Brian
Published: July 2019

Screen Bodies 3.2 engages with a wide variety of topics—fat studies, contemporary queer cinema, (pre)posterity, puzzle films, grief and truth in filmmaking, feminist materialism, digitized bodies, food and horror, and Maghrebi cinema. As well, the selection of articles in this issue represents studies of several media—tv programs, films, publicity stills, and photographs—from a number of locations around the globe—North America, Europe, Africa, and Asia. What holds this general issue together, though, is a concern over expectation, assumption, and supposition: what we suppose screens and bodies do and what we suppose they do not do. As usual, with this journal, the focus of this consideration is doublehanded: screen as projection and screen as prohibition. The articles below explore the duality of screens and our responses to them. They engage screening expectation as showing, exposing, divulging, and, at the same time, as testing, partitioning, and withholding. To screen expectation is to reveal and conceal it, and, as these articles argue—each in their own way—this process is what we all engage in when we engage with screening.
Some physiological parameters of the resistance of woody plants in the arid conditions of the Mangystau desert
Authors: Imanbayeva A. A. , Belozerov I. F.
Published: July 2019

The purpose of this study was to identify the possibility of using physiological parameters of growth and development of woody plants as markers of their tolerance to the arid conditions of the Mangistau desert zone. Using the generally accepted representative methods for 21 species of trees and shrubs, we studied the seasonal dynamics of the intensity of transpiration and water content of leaves, chlorophyll concentration and heat resistance. According to the magnitude of transpiration consumption of moisture, three groups of introducents were identified: weakly transpiring (<250 mg/g of raw leaves per hour), mediumtranspiring (250-500) and highly transpiring (> 500). A close correlation was established between the intensity of transpiration (IT) and the water content of the leaves of woody plants (r = 0.79). Soil moisture predetermines from 11.6 to 43.6 % of changes in transpiration flow (r = 0.34-0.66). The close connection between the transpiration intensity and relative humidity (r = -0.59) and air temperature (r = 0.46) is credible at 5 % significance level. With the amount of illumination it is associated statistically incredible (r = 0.19). Seasonal dynamics of IT in most introductions looks like a one-peak curve with a maximum in June. For the daytime course of transpiration changes, three types of rhythms are distinguished: “increasing” (from morning to evening), “falling” (from morning to evening) and “variable” (with a maximum at noon). The intensity of the transpiration process due to significant variability and multifactorial nature cannot be counted among the criteria for resistance of woody plants. However, at the same time, a significant correlation was revealed between the biological resistance of introducents and the coefficient of variation of IT. With an increase in its values, the tolerance of plants to arid habitat conditions usually increases due to their increased ability to self-regulate water exchange. Chlorophyll content is characterized by a double-vertex curve with a maximum in June and September. In the most biologically resistant species (elm elm, spinefly), its concentration is less susceptible to seasonal fluctuations. According to the collected research materials, the chlorophyll content cannot yet be considered a credible parameter of plant resistance, since it strongly depends on the bioecological properties of introduced species, especially in adverse conditions of the Mangistau desert. By heat resistance, plants are ranked in three groups: “low” (50 °С) – 3 species; “medium” (60 °С) – 8 and “high” (70 °С) – 3 taxon. As a genetically fixed bioecological parameter, weakly subject to intraspecific changes, it may well be used as a diagnostic characteristic of the introduction value of plants in arid conditions.

Irrational placement of crops without taking into account the “genotype-environment” interaction leads to significant economic losses, especially in conditions of climate change in the manifestation of thermal stress-factors. The purpose of the work is to ensure the stability of the perennial crops fruiting from the position of maximum realization of their hereditary basis in various growing conditions. Using the methods of genetic-physiological, biological, genetic-physiological, meteorological data and digital technologies, a new approach was proposed for managing crop productivity on the example of fruit crops varieties. The importance of the development increases dramatically due to the fact that its use provides stabilization of the fruiting of perennial crops varieties in specific areas of cultivation, taking into account climate change. Using research results will reduce the risk of yield loss from environmental stress-factors. On the basis of a long-term analysis (1986-2018), the probability of manifestation of the temperatures of the winter-spring period, which are destructive for apricot plants, has been studied in different zones of the Krasnodar Territory. The critical minimum temperatures for the fruiting of apricot genotypes of different frost resistance of Krasnoshchekiy (lowered) and 1-22 hybrid (increased), breeding of North Caucasus Federal scientific center of horticulture, viticulture, winemaking for the phases of their development were determined. The manifestations of the minimum temperatures of the winter-spring period were estimated for 30 meteorological stations of the Krasnodar Territory based on data from an analysis of exceeding their critical values in the development phases of the studied varieties. Their response (also in the context of phenological phases) to the temporal and spatial dynamics of limiting factors of the environment is analyzed. The obtained data for each meteorological station is imported into the geographic information system ILWIS, and interpolated to obtain the results of rational distribution of the studied varieties of apricot in the form of digital maps. The constructed digital maps of rational distribution of specific varieties by development phases reveal the adaptive potential of varieties in the conditions of climate change. A new approach to managing the productivity of fruit crops varieties on the example of apricot in various zones of the Krasnodar Territory is proposed.

Son yıllarda ön plana çıkan iktisadi kalkınma ve ülkelerin kalkınma tecrübelerinin karşılaştırılması ile ilgili çalışmalarda kurumsal bakış açısı önemli bir yer tutmaktadır. Söz konusu çalışmalar her ne kadar ülkeler arası gelişmişlik farklarına tarihsel yönden farklı açıklamalar getirmeye çalışsalar da tarihi kurum ve tecrübelere bakışları, bu kurumların kendi tarihsel bağlamları içinde incelenmesi ve bu kurumları ortaya çıkaran fikirsel altyapının, iktisadi sistem tasavvurunun incelenmesi anlamında eksik kalmaktadır. Bu çalışma Osmanlı Devleti tecrübesinde kurum olarak vakıfların ve özelde para vakıflarının önemini ve işlevini tarihi vesikalarla incelemekle beraber bu kurumların ortaya çıkmasına sebep olan iktisadi düşünce altyapısına dikkat çekiyor. Bunu yaparken, kurumsal teori çerçevesinde iktisat tarihi, siyasal iktisat, iktisadi kalkınma ve iktisadi fikirlerin kurumların oluşumuna yaptığı etki ile disiplinler arası bir bakış açısı ile para vakıflarını ortaya çıkaran iktisadi zihniyeti gözden geçiriyor. Bu çalışma gösteriyor ki, para vakıfları dışlayıcı değil kapsayıcı kurumlar olarak yüzyıllar boyunca tarihi şartlara uyum göstermiş, Osmanlı Devleti siyasal ve iktisadi sisteminin sürdürülebilir kılınmasında önemli etkenlerden biri olmuşlardır ve günümüzdeki sürdürülebilir ve eşitlikçi gelir paylaşımı tartışmalarına da ışık tutmaktadırlar.

Relevance. The local anesthetics were used intraperitoneally after some minimally invasive gynecological interventions like a component of postoperative multimodal anesthesia in recent years.   Objective. The aim of  work was to study the effectiveness of intraperitoneal administration  of bupivokain  for the anesthesia of patients after laparoscopic cholecystectomy. Material and methods. 28 patients aged 32-60 years  (16 women, 12 men) were examined. The patients were divided into two groups. In the first group for anesthesia after the operation, was used ketorolac trometamine in dose 0.2 mg/kg intramuscularly each 6 hours. If the patient complained of postoperative pain, which was assessed by Visual-analog scale in 7 points or higher, fentanyl was administered intramuscularly in dose of 0.003 μg/kg. In the second group, besides the components of multimodal anesthesia used in the first group, at the end of the surgical intervention at the drainage tubes were injected 40 ml of 0.125% solution of bupivocaine (50 mg). This injection was repeated throughout the first day each 6 hours. The condition of patients was assessed by a Visual-analog scale after 1, 4, 8, 12 and 24 hours after the finishing of surgery. The average dose of fentanyl in μg/kg used for postoperative anesthesia  first 24 hours after operation was also determined. Results.  We have received a significant reduction in the rates of pain evaluation for Visual-analog scale in patients who used bupivacaine as a component of multimodal anesthesia. One hour after the end of the operation, the pain score for Visual-analog scale was less than the corresponding one in the control group in 1.77 times, after 4 hours – in 1.47, and in 8 hours – in 1.55 times. In all cases, P <0.001. The mean dose of fentanyl used for treatment in the study group was 1.55 times less than that in the control group. There were no significant complications in both groups. A patient in group 1 had nausea, requiring a single dose of ondasetron 2 mg Conclusion. Intraperitoneal administration of bupivocaine had a significant  anesthetic effect after laparoscopic cholecystectomy.

Relevance. The textile industry is one of the leading industries in the light industry, in which most workers are women. However, manufacturing technologies are harmful, and equipment of enterprises is outdated. Therefore, the optimization of working conditions in the industry is extremely relevant and important for improving the demographic situation in Ukraine. Objective: to analyze literary data on working conditions in the textile industry, to identify the main hazards in the industry and their impact on the health of workers. Method. Retrospective search in Ukrainian scientific sources for 2003-2015. Results. Influence chemical (dyes, acids, alkali, formaldehyde, carbon disulfide, chlorine compounds); physical (noise, vibration, microclimate); biological factors (microorganisms in the raw material); as well as unfavourable factors of the labour process (static load, slopes of the case, awkward posture, tension of the muscles of the hands and eyes) and dust onto textile workers It was found. Workers experience changes in the functional state of the central nervous system (vegetative-vascular disorders, hearing loss); respiratory tract (laryngotracheitis, bronchitis, bronchial asthma, bisynosis); bone marrow (flatfoot, osteochondrosis, varicose disease, radiculitis); genital system (violation of reproductive function); skin diseases (dermatitis, burns) and eyes (conjunctivitis, cataracts). Conclusions. The combination of chemical agents, noise and vibration is a leading factor in the negative impact on the health of workers in the textile industry.
NEW DISCOVERIES IN THE MECHANISMS OF INTERFERON-DEPENDENT CONTROL OF LATENT ALPHA-HERPESVIRUS IN SENSORY GANGLIA. REVIEW
Authors: Maltsev D.V.
Published: July 2019

Relevance. The study of the mechanisms of immune surveillance over latent alpha herpesvirus in the sensory nerve ganglia is an important task of clinical immunology, since the data obtained during such studies may help to develop effective approaches to immunotherapy of recurrent and/or severe forms of herpes infections by restoring lost immune control over latent pathogens. Objective: to conduct a systematic review of the results of studies devoted to the study of mechanisms of intraganglionar and intraneuronal protection over latent alpha herpesvirus in sensory nerve ganglia, to develop a modern concept of immune surveillance in human alpha herpesvirus infections. Methods. Review of scientific publications in the international electronic science databases PubMed, Embase and Scopus was conducted on the keywords «alpha herpesviruses», «Toll-like receptor type 3», «natural killers», «natural killer T-cells», «intraganglionar immunity», «intraneuronal immunity» for the full time available (1972-2014). Results. The article presents modern data on interferon-dependent mechanisms of control of latent alpha herpesvirus in sensory nerve ganglia. The system of the intraganglionar control presented by resident natural killers, natural killer T-lymphocytes and cytotoxic CD8+ T-cells that are part of the satellite cells of the nerve node, and the system of intraneuronal defense contained in the centripetal fibers and presented by cascade system TLR-3 , the activation of which promote the production of interferons type I. Genetic or acquired abnormalities in intraganglionar and intraneuronal immunity systems are the cause of the development of recurrent and/or severe forms of infections caused by alpha herpesviruses in humans. Preparations of natural and recombinant alpha interferons and interferonogens are potentially useful agents in the target immunotherapy of disorders in intraganglionar and intraneuronal immunity in immunocompromised patients with severe forms of alpha herpesvirus infections. Conclusions. In the human body there are highly organized intraganglionar and intraneirononal immune control systems for latent alpha herpesviruses. The activity of these systems ensures the long stay of the virus in a latent state in the sensory nerve ganglia, and the disturbanses of the implementation of such mechanisms is responsible for reactivation of the virus from the latent state with subsequent damage to the skin, mucous membranes and/or the central nervous system.

POTENSI LARUTAN CHITOSAN 0,2% SEBAGAI ALTERNATIF BAHAN IRIGASI DALAM PERAWATAN SALURAN AKAR GIGI
Authors: Deviyanti Sinta
Published: July 2019

Irigasi dan instrumentasi merupakan salah satu faktor yang berperan penting dalam perawatan saluran akar gigi. Penggunaan instrumen manual dan instrumen yang digerakkan mesin, akan menghasilkan smear layer yang menutupi dinding saluran akar dan tubuli dentin yang terbuka.Pembersihkan debridement secara menyeluruh serta pembersihan smear layer merupakan landasan untuk mencapai keberhasilan perawatan saluran akar gigi. Irigasi dengan sodium hipoklorit (NaOCl) yang dikombinasi dengan bahan khelasi seperti Ethylenediaminetetraacetic (EDTA) telah direkomendasikan untuk pembersihan komponen organik dan komponen inorganik dari smear layer secara efektif. Namun, EDTA dapat bersifat erosif terhadap dentin, konsekuensinya mempengaruhi sifat kekerasan, permeabilitas dan pelarutan dentin di bagian dalam akar gigi. Penggunaan NaOCl tidak mampu membersihkan smear layer, karena hanya efektif terhadap debris organik. Oleh karena itu,dibutuhkan  penelitian untuk mencari larutan irigasi yang lebih kompatibel, efesien membersihkan smear layer dan menyebabkan erosi dentin yang lebih rendah. Saat ini, chitosan telah diteliti di bidang kedokteran gigi.Chitosan adalah polisakarida alamiah, berasal dari deasetilasi chitin yang terdapat pada cangkang kepiting dan udang. Chitosan memiliki kemampuan khelasi, biokompatibel, biodegradasi, bioadhesi dan tidak toksik terhadap tubuh manusia. Hasil-hasil penelitian terbaru telah menyimpulkan bahwa irigasi akhir dengan larutan Chitosan 0,2% setelah irigasi dengan larutan NaOCl, lebih efesien dalam membersihkan smear layer dibanding bahan irigasi lainnya dan menyebabkan erosi lebih sedikit pada dentin akar gigi. Chitosan dapat dipertimbangkan sebagai alternatif bahan irigasi dalam perawatan saluran akar gigi karena memiliki kemampuan khelasi pada dentin saluran akar gigi.

Disruption of the Colonization Resistance Syndrome in Humans in Altered Habitats and Its Prevention
Authors: Ilyin V. K. , Kiryukhina N. V.
Published: July 2019

Exposure of human subjects to environments with modified parameters is associated with reduced colonization resistance of the intestine and epithelial tissue, which leads to dysbiotic changes. Probiotics - preparations based on protective microflora - are used to correct dysbacteriosis of different etiologies and localizations. However, the effectiveness of probiotics largely depends on the adhesive ability of a probiotic strain and lack of competitive relations with the indigenous microflora, which can be achieved by individual selection of a preparation. We propose to use autochtonous microflora as a probiotic drug to optimize the prevention and treatment results. A personalized approach to probiotic selection will improve therapy efficiency and reduce the risk of adverse effects in each individual patient.

Preeclampsia is one of the most severe gestational complications which is one of the leading causes of maternal and perinatal morbidity and mortality. A growth in the incidence of severe and combined forms of the pathology has been observed in recent years. According to modern concepts, inadequate cytotrophoblast invasion into the spiral arteries of the uterus and development of the ischemia-reperfusion syndrome in the placental tissue play the leading role in the development of preeclampsia, which is characterized by multipleorgan failure. In this regard, our work was aimed at studying the patterns of placental tissue transcriptome that are specific to females with PE and with physiological pregnancy, as well as identifying the potential promising biomarkers and molecular mechanisms of this pathology. We have identified 63 genes whose expression proved to differ significantly in the placental tissue of females with PE and with physiological pregnancy. A cluster of differentially expressed genes (DEG) whose expression level is increased in patients with preeclampsia includes not only the known candidate genes that have been identified in many other genome-wide studies (e.g., LEP, BHLHB2, SIGLEC6, RDH13, BCL6), but also new genes (ANKRD37, SYDE1, CYBA, ITGB2, etc.), which can be considered as new biological markers of preeclampsia and are of further interest. The results of a functional annotation of DEG show that the development of preeclampsia may be related to a stress response, immune processes, the regulation of cell-cell interactions, intracellular signaling cascades, etc. In addition, the features of the differential gene expression depending on preeclampsia severity were revealed. We have found evidence of the important role of the molecular mechanisms responsible for the failure of immunological tolerance and initiation of the pro-inflammatory cascade in the development of severe preeclampsia. The results obtained elaborate the concept of the pathophysiology of preeclampsia and contain the information necessary to work out measures for targeted therapy of this disease.

Current targeting strategies for genetic vectors imply the creation of a specific vector for every targeted receptor, which is time-consuming and expensive. Therefore, the development of a universal vector system whose surface can specifically bind molecules to provide efficient targeting is of particular interest. In this study, we propose a new approach in creating targeted vectors based on the genome of human adenovirus serotype 5 carrying the modified gene of the capsid protein pIX (Ad5-EGFP-pIX-ER): recombinant pseudoadenoviral nanoparticles (RPANs). The surfaces of such RPANs are able to bind properly modified chimeric nanoantibodies that specifically recognize a particular target antigen (carcinoembryonic antigen (CEA)) with high affinity. The efficient binding of nanoantibodies (аСЕА-RE) to the RPAN capsid surfaces has been demonstrated by ELISA. The ability of the constructed vector to deliver target genes has been confirmed by experiments with the tumor cell lines A549 and Lim1215 expressing CEA. It has been shown that Ad5-EGFP-pIX-ER carrying аСЕА-RE on its surface penetrates into the tumor cell lines A549 and Lim1215 via the CAR-independent pathway three times more efficiently than unmodified RPAN and Ad5-EGFP-pIX-ER without nanoantibodies on the capsid surface. Thus, RPAN Ad5-EGFP-pIX-ER is a universal platform that may be useful for targeted gene delivery in specific cells due to nanoantibody-modified RPAN binding.

We have shown that the expression of full-length mutated huntingtin in human neuroblastoma cells (SK-N-SH) leads to an abnormal increase in calcium entry through store-operated channels. In this paper, the expression of the N-terminal fragment of mutated huntingtin (Htt138Q-1exon) is shown to be enough to provide an actual model for Huntingtons disease. We have shown that Htt138Q-1exon expression causes increased store-operated calcium entry, which is mediated by at least two types of channels in SK-N-SH cells with different reversal potentials. Calcium sensor, STIM1, is required for activation of store-operated calcium entry in these cells. The results provide grounds for considering the proteins responsible for the activation and maintenance of the store-operated calcium entry as promising targets for developing novel therapeutics for neurodegenerative diseases.

Authors: Christopher Kalema , Alim Mas'ud Zainal , Hanif Novriyandi
Published: July 2019

A simple and green tandem hydrothermal and pyrolysis method was developed for the synthesis of blue fluorescence carbon dots from coffee green bean powder and urea as raw materials. The carbon dots were characterized by ultraviolet visible spectrophotometer, Fourier-transform infrared spectroscopy and ocean optics spectrophotometer. The carbon dots had a bright blue emission centered at 505 nm under UV light with the excitation wavelength at 360 nm. The carbon dots also showed a quenching effect with lead (ii) ions and copper (ii) ions. Furthermore, a method for copper (ii) and lead (ii) ion detection in aqueous solution was developed with acceptable linearity of 97.26% and 99.41% respectively and selectivity to some common ions. The carbon dots also demonstrated the ability to act as copper corrosion inhibitors in 1% sodium chloride solution showing an inhibition efficiency of 77% at 1000 ppm. It is worth noting that the synthesized fluorescent carbon dots are eco-friendly and inexpensive. They could find application in chemical sensing and copper corrosion inhibition in salt environments.
