Ütopyalara Siyasal Teolojik Müdahale: Erken Cumhuriyet Ütopyalarının Kaynağı Olarak Cumhuriyetçi Sivil Din
Authors: ASLAN COŞKUNER Seçil , COŞKUNER Murat
Published: July 2019

Çalışma, kutsallık üreten sistemlerin ideal toplum tasavvurlarına sahip ütopya metinlerine kaynaklık ettiğine yönelik bir iddiadan yola çıkmak suretiyle erken Cumhuriyet döneminde yazılmış olan iki ütopya metni Ahmet Ağaoğlu’nun Serbest İnsanlar Ülkesindeve Yakup Kadri Karaosmanoğlu’nun Ankararomanlarını değerlendirmeyi amaçlamaktadır. Literatürde İslam’ın, Doğu toplumlarında ütopya yazınını engellediği iddiasının aksine çalışma kapsamında kutsallık sadece tek tanrılı dinlere özgü bir olgu olarak ele alınmamakta, alternatif kutsallık mekanizması olarak siyasal-sivil kutsallığa odaklanılmaktadır. Bu bağlamda; siyasal-sivil kutsallık mekanizmalarının ütopyalara kaynaklık ettiği tezinden hareketle gerekAnkara, gerek Serbest İnsanlar Ülkesinderomanlarının erken Cumhuriyet döneminde bir takım kültler ve kutsallık mekanizmaları oluşturmuş olan cumhuriyetçi sivil din vasıtasıyla ortaya çıkabildikleri ve ondan beslendikleri gösterilmeye çalışılmaktadır. İlgili ütopyaları metin analizi yöntemiyle inceleyen çalışma, onların bu alternatif kutsallıktan yoğun bir şekilde beslenmekle kalmayıp aynı zamanda bu kutsallığın bir aracı ve parçası haline geldiklerini savunmaktadır.
Luki konstrukcyjne w prawie ochrony środowiska - wykładnia i stosowanie
Authors: Haładyj Anna
Published: July 2019

Prawo ochrony środowiska wykazuje daleko idącą specyfikę jeśli chodzi o przedmiot regulacji, a tym samym – specyfikę regulującej go materii ustawowej. Nasilającą się tendencją jest nie tylko mnogość regulacji podustawowej, ale i zjawisko zaniechania legislacyjnego polegające na niewydaniu obligatoryjnych rozporządzeń wykonawczych. Celem pracy jest ocena możliwości zastosowania analogii jako metody stosowania/wykładni prawa w przypadku braku regulacji podustawowej, określenia warunków dopuszczalności jej zastosowania oraz możliwych skutków takiej analogii. W opracowaniu ujęto także propozycję interpretacji prawa w przypadku niedopuszczalności zastosowania analogii, tj. interpretacji  wątpliwości co do treści normy prawnej na rzecz strony.
Oxygen and silicon β-factors of zircon estimated from first principles
Authors: Krylov D. P.
Published: July 2019

Zircon β-factors have been calibrated against temperature for isotopic substitutions of 18O/16O and 30Si/28Si. Calculations were performed using the density functional theory (DFT) with the “frozen phonon” approach. The deduced geometric parameters of the zircon unit cell, and the phonon frequencies calculated, agree well with the experimental data. The results are expressed by the cubic polynomials on x = 106/T(K)2: 1000lnβzrn(18O/16O) = 9.83055x – 0.19499x2 + 0.00388x3;  1000lnβzrn(30Si/28Si) = 7.89907x – 0.17978x2 + 0.00377x3.

The expressions deduced can be utilized to construct geothermometers if combined with β-factors of coexisting phases. New calibrations of quartz-zircon are given. The new values of 1000lnβzrn and the estimated isotope fractionation factors between quartz and zircon (1000lnβqtz–1000lnβzrn) deviate considerably from previously used experimental, empirical, and semi-empirical calibration of the isotopic equilibrium.
Behavior of the 238U, 235U, and 234U isotopes at weathering of volcanic rocks with u mineralization: a case study at the Tulukuevskoe deposit, Eastern Transbaikalia

Published: July 2019

The trend fractionation of the 238U and 235U isotopes and the extent of this process at the oxidative weathering of uranium minerals were evaluated by studying the variations in the U isotope composition of rocks, minerals, and fracture waters sampled in the quarry of the broadly known Tulukuevskoe uranium deposit in the Streltsovskoe ore field, eastern Transbaikalia. In the rock block in question, fine uranium minerals disseminated in the rocks were weathered under the effect of oxidizing fracture waters. Uranium isotope composition was measured in 22 water samples, eleven samples of the mineralized rocks, and eight uranium minerals. High-precision (±0.07‰, 2SD) measurements of the 238U/235U were carried out by MC-ICP-MS, using a 233U–236U double spike. The results involve the 238U/235U and 234U/238U ratios and the overall range of the δ238U variations determined in the rocks and waters (from –0.13 to –1.0‰ and from –0.22 to –0.59‰, respectively). Interaction between the waters and rocks induces U(IV) → U(VI) oxidation, U(VI) transfer into the aqueous phase, and 0.15–0.28‰ enrichment of U dissolved in the water in the 235U isotope. When the pitchblende is replaced by U(VI) minerals, the 238U and 235U isotopes also fractionate with ~0.3‰ enrichment of the younger U(VI) mineral phases in the light 235U isotope. The 238U/235U and 234U/238U ratios are proved to correlate, and hence, the fractionation of the 238U and 235U isotopes and the enrichment of the aqueous phase in the light 235U isotope proceed simultaneously with the well known shift in equilibrium the 238U–234U system with the accumulation of excess amounts of the 234U in the aqueous phase. Uranium leaching from uranium minerals, which is associated with the enrichment of the aqueous phase in excess amounts of the 234U isotope, can be viewed as a process that controls isotope fractionation in the 238U–235U system. This should be taken into account in describing the fractionation mechanism of the 238U and 235U isotopes at U(IV) → U(VI) oxidation. The fractionation of the 238U and 235U isotopes, which results in the isotopic "lightening" of U in the aqueous phase, largely controlled the complicated distribution pattern of the 238U/235U ratio in the quarry. In addition to isotope fractionation, this distribution was likely also affected by isotope exchange between uranium dissolved in the water and uranium in the finely dispersed minerals. The isotopically light uranium of the water could participate in forming U(VI) minerals at lower levels of the quarry.

Feminismo, discurso mediático y percepción social
Authors: Pérez–Tirado Irene
Published: July 2019

En 2017, la eclosión de las reivindicaciones feministas irrumpió con firmeza en el foco de los debates de la opinión pública. Ante esta realidad, este estudio considera que la comunicación del mensaje del movimiento feminista y la percepción social del mismo exigen mayor exploración, reflexión y clarificación. Los medios de comunicación (en adelante, MMCC) no solo proyectan, sino que construyen la realidad y modulan nuestras percepciones en torno a aspectos como el que aquí se estudia. Para analizar la incidencia de las reivindicaciones sociales, se aplica el Análisis Crítico del Discurso (en adelante, ACD) a un corpus seleccionado de artículos de prensa. Igualmente es preciso calibrar y analizar la percepción social que la ciudadanía tiene de los fenómenos que acontecen. El feminismo, a pesar de abogar por unos principios de evidente equidad y tras varios siglos de pedagogía, continúa resultando un término confuso y generador de sentimientos ambivalentes.

Authors: Kulshrestha Dr. Manish , Kulshrestha Dr. Anjali
Published: July 2019

INTRODUCTION: Enteric fever includes typhoid and paratyphoid fever. Peak incidence is seen in children 5–15 years of age; but in regions where the disease is highly endemic, as in India, children younger than 5 years of age may have the highest infection rates. There are about 22 million new typhoid cases occur each year. Young children in poor, resource limited areas, who make up the majority of the new cases and there is a mortality figures of 215,000 deaths annually. A sharp decline in the rates of complications and mortality due to typhoid fever is observed as a result of introduction of effective antibiotic therapy since 1950s. MDR-ST became endemic in many areas of Asia, including India soon after multidrug-resistant strains of Salmonella enterica serotype typhi (MDR-ST) that were resistant to all the three first-line drugs then in use, namely chloramphenicol, amoxycillin and co-trimoxazole emerged in early 1990s.

MATERIAL AND METHODS: Only blood culture or bone marrow culture positive cases were included. The patients with culture isolated enteric fever were included in the study. Antimicrobial susceptibility testing was carried out by disk diffusion method using antibiotic discs. The analysis of the antimicrobial susceptibility was carried out as per CLSI interpretative guidelines.

RESULTS: A total of 82 culture positive cases were included in the present study. 80 culture isolates were from blood culture and 2 from the bone marrow culture. Salmonella entericasubspecies enterica serovartyphi (S typhi) was isolated from 67 (81.70%) patients while Salmonella enterica subspecies entericaserovarparatyphi (S paratyphi A) was isolated from 13 (15.85%) cases and 2 (2.44%) were Salmonella enterica subspecies entericaserovarschottmuelleri (S paratyphi B). Of the 82 cases 65(79.3%) isolates were resistant to ciprofloxacin, 17 (20.7%) were resistant to nalidixic acid, one (1.2%) case each was resistant to Cefotaxime and ceftriaxone, 2 (2.4%) were resistant to chloramphenicol, 10 (12.2%) were resistant and to cotrimoxazole 3 (3.7%) were resistant.

CONCLUSION: In a culture positive cases 65(79.3%) isolates were resistant to ciprofloxacin and 17 (20.7%) were resistant to nalidixic acid. Multidrug resistant isolates were 65(79.3%).

BEHAVIOURAL PAIN SCALE TO ASSESS PAIN IN SEDATED AND CONSCIOUS PATIENTS
Authors: Kirankumar Dr. H.
Published: July 2019

INTRODUCTION: Pain prevalence estimates vary by population and setting, it is about 46-80% of individuals with chronic or terminal illnesses in hospital. This pain is significant to cause both physical and psychological distress, interferes with activities of daily living, predisposes to development of adverse sequelae, impairs quality of life, and ultimately delays healing and recovery. There are various barriers for effective verbal communication in these patients such as sedation, decreased level of consciousness, endotracheal intubation, and mechanical ventilation, which are limiting factors for patients self-report of pain. To report this pain, some behavioural and physical responses can be used to assess and diagnose the pain. BPS can be used to assess pain before and after the two common procedures in unconscious ICU-admitted patients and it was reported to be a valid and reliable tool in evaluation of the pain of unconscious patients. 

MATERIAL AND METHODS: patients admitted to the ICU were evaluated for inclusion in the study once a day. Patients who were above 18 years, sedated, and ventilated for at least 8 h before assessment were included in the study. Measurement of pain by BPS scale was done by 2 observers and was recorded. Written informed consent from the patient’s relatives was obtained. Pain ranking is from 3 to 12, and the patient's status considered based on this scale is painless as 3, mild from 4–6, moderate from 7–9, or severe if ranged between10–12 pain. The scores of 6 and higher indicate moderate-to-severe pain.

RESULTS: In present study 100 patients were included.  71% patients were sedated state on all days while 18% cases were in consciously sedated state on all days and 11% patients were either in sedated or conscious sedated state on different days. 59.1% cases were male among those who were in sedated state on all days, where as 66.7% and 63.6% were males among those who were in conscious sedated state on all days and in either state on different days respectively. The amount of protocol administered was 128.9 ± 55.3 mg/hr for conscious sedated patients whereas it was 172.3 ± 72.6 mg/hr for sedated patients (P < 0.05). The difference was observed to be statistically significant. The amount of midazolam given to conscious sedated patients and sedated patients was 2.9 ± 1.8 vs 3.8 ± 2.3 mg/hr (P = 0.12). Total BPS in conscious sedated patients during rest was 3.7 ± 0.5 and during painful procedure was 5.2±1.1 this was highly significant. BPS facial expression during painful procedures Facial expression BPS was 2.4±0.9 and during rest it was 1.0±0.2. It was highly significant. CONCLUSION: For conscious sedated patients the BPS system can be validly and reliably used during painful procedures. BPS is a sensitive scale for capturing changes in pain response and discriminates between painful and nonpainful procedures.
The Effect of Melaxen on the Activity of Caspases and the Glutathione Antioxidant System in Toxic Liver Injury
Authors: Popov S. S. , Shulgin K. K. , Pashkov A. N. , Agarkov A. A.
Published: July 2019

A comparative study of the activity of caspase-1 and caspase-3, the glutathione antioxidant system and NADPH-generating enzymes (glucose-6-phosphate dehydrogenase and NADP-isocitrate dehydrogenase) and a study of DNA fragmentation in the blood serum of patients with chronic alcoholic hepatitis during basic treatment and combination therapy including melaxen have been carried out. It was found that the blood serum level of reduced glutathione, which decreases in pathology, increased more significantly in patients receiving melaxen as compared to the group of patients receiving the standard treatment. More significant changes in the activity of caspase-1 and caspase-3, glutathione reductase, glutathione peroxidase, glutathione-S-transferase, glucose-6-phosphate dehydrogenase and NADP-isocitrate dehydrogenase toward the control values were observed during the combination therapy. The correction in the melatonin level under the influence of melaxen apparently had a positive effect on the free-radical homeostasis in patients, which resulted in more pronounced changes in the investigated parameters towards the normal values as compared to the basic treatment.

Telomere length, an important feature of life span control, is dependent on the activity of telomerase (a key enzyme of the telomere-length-maintaining system). Telomerase RNA is a component of telomerase and, thus, is crucial for its activity. The structures of telomerase RNA genes and their promoter regions were compared for the long-living naked mole rat and different organisms. Two rare polymorphisms in Heterocephalus glaber telomerase RNA (hgTER) were identified: AG in the first loop of pseudoknot P2b-p3 (an equivalent of 111nt in hTR) and GA in the scaRNA domain CR7-p8b (an equivalent of 421nt in hTR). Analysis of TER promoter regions allowed us to identify two new transcription factor binding sites. The first one is the ETS family site, which was found to be a conserved element for all the analyzed TER promoters. The second site is unique for the promoter region of TER of the naked mole rat and is a binding site for the SOX17 transcription factor. The absence of one Sp1 site in the TER promoter region of the naked small rat is an additional specific feature of the promoter area of hgTER. Such variation in the hgTER transcription regulation region and hgTER itself could provide increased telomerase activity in stem cells and an extended lifespan to H. glaber.

The speculations on the role of MUC1, a substance which is overexpressed in glandular cancer cells, on the metastatic potential of such cells are rooted in data that seem to indicate that cell malignization correlates with a change from the apical localization of mucin MUC1 to a peripheral one. Nonetheless, the role of MUC1 in cancer metastasizing remains far from clear. The major hurdle remains the absence of adequate cell models. The aim of the present study was to create cell models that present different fragments of the human mucin MUC1 extracellular domain on their surface. Genetic constructions were generated on the basis of the plasmid vector pEGFP-N3. These constructions contain fusion genes coding for chimeric proteins composed of different combinations of mucin MUC1 functional domains and identification markers (FLAG-epitope, located at the N-terminus, and EGFP, located at the C-terminus of the chimeric proteins). These constructions were used for a stable transformation of HT-29 human cancer cells. The transformants obtained were characterized by flow cytometry. The low expression level of endogenous mucin MUC1 and the high expression level of recombinant proteins were confirmed by real-time PCR. The microscopic examination of the transformed cells confirmed the membrane localization of the fusion proteins. The resulting cell models could be used to investigate the role of the mucin MUC1 domains in cancer cell metastasizing. The obtained cells are used as an applicable model of MUC1-expressing cancers and might be used to study the role of different functional fragments of mucin MUC1 in metastasizing.

Lipid-protein nanodiscs (LPNs) are nanoscaled fragments of a lipid bilayer stabilized in solution by the apolipoprotein or a special membrane scaffold protein (MSP). In this work, the applicability of LPN-based membrane mimetics in the investigation of water-soluble membrane-active peptides was studied. It was shown that a pore-forming antimicrobial peptide arenicin-2 from marine lugworm (charge of +6) disintegrates LPNs containing both zwitterionic phosphatidylcholine (PC) and anionic phosphatidylglycerol (PG) lipids. In contrast, the spider toxin VSTx1 (charge of +3), a modifier of Kv channel gating, effectively binds to the LPNs containing anionic lipids (POPC/DOPG, 3 : 1) and does not cause their disruption. VSTx1 has a lower affinity to LPNs containing zwitterionic lipids (POPC), and it weakly interacts with the protein component of nanodiscs, MSP (charge of -6). The neurotoxin II (NTII, charge of +4) from cobra venom, an inhibitor of the nicotinic acetylcholine receptor, shows a comparatively low affinity to LPNs containing anionic lipids (POPC/DOPG, 3 : 1 or POPC/DOPS, 4 : 1), and it does not bind to LPNs/POPC. The obtained data show that NTII interacts with the LPN/POPC/DOPS surface in several orientations, and that the exchange process among complexes with different topologies proceeds fast on the NMR timescale. Only one of the possible NTII orientations allows for the previously proposed specific interaction between the toxin and the polar head group of phosphatidylserine from the receptor environment (Lesovoy et al., Biophys. J. 2009. V. 97. № 7. P. 2089-2097). These results indicate that LPNs can be used in structural and functional studies of water-soluble membrane-active peptides (probably except pore-forming ones) and in studies of the molecular mechanisms of peptide-membrane interaction.

Published: July 2019

Precise studies of plant, animal and human genomes enable remarkable opportunities of obtained data application in biotechnology and medicine. However, knowing nucleotide sequences isnt enough for understanding of particular genomic elements functional relationship and their role in phenotype formation and disease pathogenesis. In post-genomic era methods allowing genomic DNA sequences manipulation, visualization and regulation of gene expression are rapidly evolving. Though, there are few methods, that meet high standards of efficiency, safety and accessibility for a wide range of researchers. In 2011 and 2013 novel methods of genome editing appeared - this are TALEN (Transcription Activator-Like Effector Nucleases) and CRISPR (Clustered Regulatory Interspaced Short Palindromic Repeats)/Cas9 systems. Although TALEN and CRISPR/Cas9 appeared recently, these systems have proved to be effective and reliable tools for genome engineering. Here we generally review application of these systems for genome editing in conventional model objects of current biology, functional genome screening, cell-based human hereditary disease modeling, epigenome studies and visualization of cellular processes. Additionally, we review general strategies for designing TALEN and CRISPR/Cas9 and analyzing their activity. We also discuss some obstacles researcher can face using these genome editing tools.

Several new actinoporin isoforms with molecular weights of 18995.5 to 19398.7 Da exhibiting a high hemolytic activity were isolated from the tropical sea anemone Heteractis crispa using a combination of liquid chromatography techniques. The actinoporins were demonstrated to occur as mono-, di-, and trimers in aqueous solutions. The sequences of the genes encoding actinoporins were identified, and the amino acid sequences of the new polypeptides belonging to the Hct-A actinoporin family were obtained. The new acinoporins differ in their isoelectric points, the number and localization of charged amino acid residues at the functionally important N-terminal fragment of the molecule, as well as in the charge of a tetrapeptide (amino acid residues 74-77) involved in an electrostatic interaction with the cytoplasmic membrane. A recombinant actinoporin, rHct-A2, with a molecular weight of 19141 Da, pI of 9.64, and hemolytic activity of 4.0 104 HU/mg, was obtained. The conductivity of the ion channels formed by rHct-A2 in the BLM was demonstrated to be similar to that of the native actinoporin from H. crispa. The obtained data expand knowledge on the structural and functional relationships of actinoporins and contribute to our understanding of the functioning mechanism of these molecules, which is the basis for the development of compounds with a high biomedical potential. Currently, they are considered as models for obtaining antitumor, antibacterial, and cardiac-stimulating agents.
