CircRNA-UCK2 increased TET1 inhibits proliferation and invasion of prostate cancer cells via sponge miRNA-767-5p
Authors: Xiang Zhendong , Xu Chengdang , Wu Gang , Liu Bo , Wu Denglong
Published: November 2019

A majority of the patients with advanced prostate cancer initially respond to androgen deprivation therapy and enzalutamide therapy, but eventually enter the castration-resistant prostate cancer (CRPC) phase. Some studies have shown that the activation of other signalling pathways in CRPC cells replaces the function of the androgen receptor, as well as promotes cell metastasis and progression. However, the mechanisms underlying this side effect remain unclear. The present study aims to explore the continued progression of cells after enzalutamide resistance. Low expression of circRNA-UCK2 (circUCK2) was detected in enzalutamide-resistant (EnzR) cells. Moreover, miR-767-5p was found to be resistant to EnzR cells when the level of circUCK2 is increased. The decrease in free miR-767-5p increases the expression of TET1 protein through the post-transcriptional regulation of mRNA, thereby inhibiting cell invasion and proliferation. Knocking down circUCK2 in enzalutamide-sensitive cells reduces the concentration of TET1, thereby increasing cell invasion and proliferation. A preclinical study using in vivo mouse models also showed that a high expression of circUCK2 inhibited the EnzR cell growth. Thus, this study might aid in developing a novel therapy to better suppress the CRPC progression.
Entwaffnung, Demobilisierung und Reintegration: Ein unzureichend genutztes Instrument der Diplomatie im Jemen
Authors: Jachnik Clive
Published: November 2019

Entwaffnung, Demobilisierung und Reintegration (DD&R) ist der Prozess der Abgabe von Waffen durch Mitglieder bewaffneter Gruppen, der Herausnahme der Ex-Kombattanten aus ihren Gruppen und der Unterstützung bei ihrer Rückkehr in ein normales Leben. DD&R kann in Gemeinschaften, die von Konflikten betroffen sind, einen erheblichen Beitrag zur Wiederherstellung des Friedens leisten. Im Lauf der Zeit hat das UN-DD&R sein Aktivitätsfeld erweitert; zu seinen strategischen Prioritäten gehört mittlerweile auch das Bemühen, Verzahnungen mit politischen Prozessen sicherzustellen. Im Hinblick auf die Situation im Jemen hat das UN Yemen DD&R Forum allerding die Breite der UN-DD&R-Programme völlig missverstanden und sich sogar dafür ausgesprochen, vor der Unterzeichnung eines Friedensabkommens sämtliche DD&R-Initiativen im Jemen einzustellen. Überdies hat das Forum es unterlassen, andere UN-Organisationen oder wichtige Stakeholder für die Möglichkeiten von Prä-DD&R oder Kommunaler Gewaltreduzierung (CVR) zu sensibilisieren. Dies hat dazu geführt, dass die Planungen sowohl für DD&R- als auch für Stabilisierungsbemühungen im Jemen unzureichend gewesen sind bzw. praktisch gar nicht erfolgten.
Intervention with an educational video after a whiplash trauma – a randomised controlled clinical trial
Authors: Rydman Eric , Ottosson Carin , Ponzer Sari , Dahl Anna , Eneqvist Ted , Järnbert-Pettersson Hans , Kasina Piotr
Published: November 2019

Background and aims

Previous systematic reviews have considered that providing patient information is ineffective for patients with whiplash-associated disorders (WAD), with the exception of interventional educational videos. The aim of this randomised controlled clinical trial was to determine if use of an educational video as an intervention in the acute stage after a whiplash injury might improve self-reported recovery at 6 months after the injury.

Methods

In total, 289 consecutive patients with a whiplash injury following a motor vehicle collision were randomised to an intervention group (educational video) or to a control group (written information sheet). The video focused on information about pain mechanisms, deep flexor physiotherapy and reassurance. Emailed questionnaires were used to collect baseline data within 2 weeks after the accident and then to collect outcome data at 6 months post-injury. Non-responders were followed up with a brief telephone interview regarding the outcome. The primary outcome measure was self-reported recovery (yes/no) at 6 months post-injury. The secondary outcomes measures were pain level according to a numeric rating scale (NRS) and the whiplash disability questionnaire (WDQ) score at the same time point.

Results

The response rate for the baseline questionnaire was 70% (203/289). The follow-up rate was 97% (196/203). The non-recovery rates were similar between the intervention group, at 37.9% (39/103), and the control group, at 33.3% (31/93) (p = 0.55). No differences between the groups were noted in pain levels, NRS scores (1.9 vs. 2.2, p = 0.35) or the mean WDQ scores (17.5 vs. 21.2, p = 0.42).

Conclusions

The intervention with the educational video used in this study had no effect on the non-recovery rate when compared to a basic written information sheet.

Implications

The results of this trial add knowledge to the area of patient education for patients with acute WAD. Further studies are needed before the current recommendations for patient information are modified.
Native Insurgent Literacy in Colonial California
Authors: Hackel Steven W.
Published: November 2019

The catastrophe of Spanish colonization for California's indigenous populations has made it easy for historians to overlook the skills that some Indians learned in the missions and the ways in which those who survived the missions used these hard-won skills to resist colonial rule and advance their own interests. One such skill was alphabetic literacy, which a select few California Indians in the missions acquired and used in their own distinctive ways. Focusing on the experiences of a few heretofore obscure yet important individuals, this article briefly compares the experiences with alphabetic literacy of Indian men and women over the first few generations of contact and explores the degree to which literacy provided Indians with the means to serve their communities, reinvent themselves, and challenge missionaries’ expectations.
Rewriting the Narrative
Authors: Rosenthal Nicolas G.
Published: November 2019

A vibrant American Indian art scene developed in California from the 1960s to the 1980s, with links to a broader indigenous arts movement. Native American artists working in the state produced and exhibited paintings, prints, sculptures, mixed media, and other art forms that validated and documented their cultures, interpreted their history, asserted their survival, and explored their experiences in modern society. Building on recent scholarship that examines American Indian migration, urbanization, and activism in the twentieth century, this article charts these developments and argues that American Indian artists in California challenged and rewrote dominant historical narratives by foregrounding Native American perspectives in their work.

Awards as Value Imperatives of a State and Society
Authors: Bubnova Irina
Published: November 2019

The article presents the results of a study on the texts and decrees on awarding and statutes of the highest orders of the USSR and modern Russia - the Order of Lenin and the Order of St. Andrew the First-Called. The purpose of the study was to identify the virtue imperatives that meet main goals of some stage in the state's development and transmit them through civil decorations in order to construe a sociocultural layer of a value picture of the world and, accordingly, to design a type of personality with a set of socially welcomed models of behavior, that is being in demand at a certain time period. The texts of decrees and statutes are analyzed with the reference to a method of content analysis, which resulted in distinction between the leading super-topical themes that are viewed as a reflection of a required public interest. Verification and clarification of the results was continued with a text compression method and conclusion on the virtue imperatives of both historical periods under study. In the USSR industrialization, ideological construction associated with the formation of moral excellence coordinates of the individual, the development of agriculture and science were (in descending order) of leading value, which in general corresponds to the main functions of the governmental institution. The leading virtue imperative of modern Russia is the sphere of ideology, meanwhile, reassessment of the value system is based primarily on samples of the Soviet past, which causes cognitive dissonance and can lead to unpredictable results.
RELAÇÃO CENTRO X PERIFERIA: A UNIVERSIDADE EM DEBATE
Authors: MAZZETTI ANTÔNIO CARLOS , RUBIN-OLIVEIRA MARLIZE , PEZARICO GIOVANNA , WIELEWICKI HAMILTON DE GODOY
Published: November 2019

RESUMO: Este artigo objetiva problematizar a complexidade da relação centro-periferia no contexto da universidade latino-americana, da internacionalização da Educação Superior e do conhecimento científico. A problemática busca sustentação nos conceitos de capital científico de Bourdieu; de relação centro-periferia, em Kreimer e de racionalidade hegemônica em Sousa Santos. Discute-se a universidade enquanto espaço de reprodução e/ou tensionamento da racionalidade, frente a novos contextos, como a internacionalização/mercantilização da Educação Superior e as classificações de rankings internacionais dominados por instituições de países centrais. Neste cenário, o conhecimento/ciência produzido na periferia precisa recuperar a universidade como espaço contra-hegemônico. A educação, compreendida como bem público - em universidades da América Latina - pode potencializar e fortalecer políticas e ações contra-hegemônicas, buscando uma inserção propositiva na realidade global.
COSMOPOLITISMO E PERFORMATIVIDADE: CATEGORIAS PARA UMA ANÁLISE DAS COMPETÊNCIAS NA BASE NACIONAL COMUM CURRICULAR
Authors: Melo Alessandro de , Marochi Ana Claudia
Published: November 2019

RESUMO: O artigo discute as categorias de conformação das subjetividades adaptadas ao cenário social de crise do capital, especificamente as categorias cosmopolitismo e performatividade, e como a categoria de competências, enfatizada na Base Nacional Comum Curricular, se relaciona com elas. As reformas educativas neoliberais possuem o papel de produzir conformismo por meio da formação unilateral para o trabalho e para uma cidadania adequada às características deste tempo: precariedade do trabalho e aumento do desemprego, competitividade, repressão do Estado e o aniquilamento das resistências da classe trabalhadora e, como pano de fundo ideológico, o processo de deslocamento das responsabilidades para o âmbito individual. As competências são uma forma de adaptação do projeto educacional a este tipo de sociabilidade, que esvazia as qualificações profissionais para percursos laborais individuais, inseguros, sujeitos a constantes avaliações. Assim, o cosmopolita, como empreendedor de si mesmo, é o projeto de formação humana adequada ao espírito performático neoliberal.

Published: November 2019

Abstract Recent crisis and conflicts in African countries, the Middle East and the Americas have led to forced population migration and rekindled concern about food security. This article aims to map in the scientific literature the implications of forced migration on food and nutrition of refugees. Scoping Review, and database search: databases: PubMed Central, LILACS, SciElo, Science Direct and MEDLINE. Languages used in the survey were: English, Portuguese and Spanish, with publication year from 2013 to 2018. 173 articles were obtained and after removing of duplicates and full reading, 26 articles were selected and submitted to critical reading by two reviewers, resulting in 18 articles selected. From the analysis of the resulting articles, the following categories emerged: Food Inequity; Cultural Adaptation and Nutrition; Emerging Diseases and Strategies for the Promotion of Nutritional Health. Food insecurity is a marked consequence of forced international migration, and constitutes an emerging global public health problem, since concomitant with increasing population displacements also widens the range of chronic and nutritional diseases.

Authors: CAN Mehmet Fatih , BOZKURT Ahmet
Published: November 2019

In this study, different populations of a copepod species, Mesocyclops leuckarti, were compared with their body size. Samples were taken from Asi River, Mehmetli Dam Lake, Yenişehir Lake, and Tahta Köprü Dam Lake, locating in east-south part of Turkey. Whole sexual dimorphism for the populations was changed from 1.56 to 1.62. Intra-population variability on body size by locations were changed as 3.85 % to 5.05 %. Intra-population variability was bigger in male than that of female populations in each water body. The same pattern was observed for inter-population variability among male populations (8.46 %) and female populations (8.04 %). Discriminant analysis (DFA) and SIMPER (Similarity Percentage) methods revealed that Cephalozom Length (CL) measurementwas the most distinguished measure leading discriminate among the male populations with 23.97 %. Abdomen (ABD) measurement was the most discriminative measure among female populations with 30.86 %. Based on the MANOVA, the differentiation in body size among the female populations was very significant (p<0.001), contrary to male populations (p>0.05).The Minimal Spanning Tree (MST) analysis showed that the specimen living in the pond and lake systems were closer than river systems in terms of body size diversification especially for female ones of copepods.
Influence of the Thermophysical Properties of a Liquid Coolant on Characteristics of the 3D Flows with Phase Transition
Authors: Bekezhanova Victoria B. , Goncharova Olga N.
Published: November 2019

Regimes of the joint flows of the evaporating liquid and gas – vapor mixture induced by the action of a longitudinal temperature gradient in a three-dimensional channel of a rectangular cross-section in the terrestrial gravity field are studied in the present paper. The theoretical investigations are carried out on the basis of the partially invariant solution of rank 2 and defect 3 of the Boussinesq approximation of the Navier – Stokes equations. This solution allows one to correctly describe the two-layer flows with evapora- tion/condensation at the thermocapillary interface and to take into account the effects of thermodiffusion and diffusive thermal conductivity in the gas–vapor phase. The exact solution of governing equations are characterized by dependence of the velocity components on the transverse coordinates only. The functions of pressure, temperature and concentration of vapor linearly depend on the longitudinal coordinate and have the summands which are functions on transverse coordinates. The required functions satisfy the set of differential equations, boundary and interface conditions followed from the original three-dimensional problem statement and are found as a result of numerical technique. The presented solution of the evap- orative convection problem is very contensive. It permits to specify the 3D flow regimes with different topology, thermal and concentration characteristics observed in physical experiments. Differences of flows in the ethanol–nitrogen, HFE-7100 – nitrogen and FC-72 – nitrogen systems are studied. Impact of the thermophysical properties of the working liquids on the basic characteristics of the fluid motions (hydro- dynamical structure, temperature distribution, vapor content in the nitrogen, evaporative mass flow rate) is analyzed

The role of a neurologist in deciding on the treatment options in epilepsy: therapy and/or surgery
Authors: Voronkova K. V. , Fedin A. I. , Nikitin A. E. , Zuev A. A. , Pedyash N. V. , Bochaeva D. M.
Published: November 2019

The existing approaches to treating epilepsy can be classified as therapeutic and/or surgical. In most cases, a patient with epilepsy is examined by a neurologist (or psychiatrist) and receives antiepileptic drugs (AEDs) in order to control seizures. And it is the neurologist who decides on referring the patient to the surgeon for further treatment if the medications have no effect. Undoubtedly, there are situations when, during the initial examination, the doctor reveals life-threatening lesions or brain abnormalities, which unequivocally indicate the necessity of surgical treatment. The present article addresses the issues of professional caution required from the neurologist in less-obvious clinical cases, when the doctor has to rely on his/her own clinical judgement in order to identify the “surgical” situations and refer the patient to a neurosurgeon for an adequate treatment.

IDENTIFICATION THEORY AND ITS ROLE IN COPYCAT CRIMES
Authors: Gratkovskis Daniels Bernards
Published: November 2019

The reasons for the copycat crimes at the moment are a “white spot” in criminology. Theories explaining the origins of human behaviour can help in filling it out. Skinner’s and Bandura’s behavioristic theories explain the copycat process with the action of operant conditioning and the learning of aggression, respectively. Confronting the escape process from freedom is one of the reasons why a person can go against social norms and laws. These theories conclude in the cognitive theory of identification, which currently most extensively explains the mechanism of imitation, as well as is taking into concideration the influence of the media, an important actor in the mechanism of copycat crimes, on a person and vice versa.

Non-insulin dependent diabetes mellitus and risk factors: a case control study from Andhra Pradesh
Authors: Shruti P. , Takalkar Anant A.
Published: November 2019

Background: It is well known that several factors influence the development of non-insulin dependent diabetes mellitus (NIDDM) such as genetic, environmental and life style factors. Obesity is the strongest modifiable risk factor for NIDDM. Cigarette smoking and alcohol consumption may also have important roles, either indirectly through their effects on obesity or directly through physiological factors related to insulin secretion or insulin resistance. The objective of the study was to study the risk factors of non-insulin dependent diabetes mellitus among the patients attending Chalmeda Anand Rao Institute of Medical Sciences Hospital.Methods: It is a hospital-based case-control study for risk factors in NIDDM. The study was conducted at Chalmeda Anand Rao Institute of Medical Sciences, Karimnagar during the period of June 2010 to May 2011 involving 147 cases and controls each. Data collected and analyzed using SPSS 14 version.Results: 21.59% of the male cases were in the age group of 46-50 years and 20.97% female cases from 56-60 yrs age. 42% cases and 12% controls had history of diabetes mellitus in one parent. 34% cases and 4.67% controls had history of diabetes mellitus in both the parents. Current smokers (odds ratio-4.24, 95% CI 2.02-9.15) and ex-smokers (odds ratio-1.31, 95% CI 0.65-2.68) exhibited an increased risk of NIDDM. Ex-drinking but not current-drinking was statistically significantly associated with the risk of NIDDM. Sedentary work was associated with an increased risk of NIDDM with an odds ratio of 3.90 (95% CI 2.30-6.63).Conclusions: Apart from other risk factors, smoking and alcohol consumption are significant lifestyle risk factors for NIDDM in males.

MODELING THE GROWTH RATES OF ALIEN INSECTS SPECIFIED DIFFERENTIATED BY STAGES OF ONTOGENESIS
Authors: Perevaryukha A. Yu.
Published: November 2019

Our studies are devoted to various aspects of invasive processes in biosystems. When invading aggressive insects, the resistance of the biotic environment is signiﬁcant, but the ﬁnal time may be completely absent. Under conditions of high speciﬁc fecundity, there will be non-stationary regimes of changes in the abundance of individuals in the population. An outbreak with a phase of explosive growth is realized, so we modeled one particular variant of an outbreak of populations earlier. Outbreaks are associated with a number of changes in physiological regulation that are observed in ecodynamics under extreme conditions of the species and environment. A classic example of changes is the appearance of migratory winged forms in the locust and the usually ﬂightless leaf beetle introduced in the Stavropol Territory Zygogramma suturalis during the formation of a population wave front with a huge density of individuals. Traditional mathematical models for describing the rates of average weight gain for individuals of a generation cannot consider situations of rapid invasions, where competition and survival factors at diﬀerent stages of insect development are very diﬀerent, since the density of generations varies by orders of magnitude. Eﬀect on growth of local congestion value may not be constant in ontogenesis. The factor of the total number is reﬂected diﬀerently at diﬀerent stages of life. The purpose of the simulation is to obtain a bistable and ﬂexible dynamic system. The article proposes a model for a diﬀerentiated description of weight gain at three stages of development of insects with an incomplete cycle of transformations by three diﬀerential equations conjugated by initial conditions. As a result, a continuously discrete dynamic system with a hybrid representation of time on the life cycle interval is implemented. We will use the model when supplementing the hybrid computing structure for calculating the rate of decline of individuals of generations. Mortality changes dramatically with the launch and attenuation of an invasive outbreak. Here, the deviation of growth rates from optimal values plays a role. The idea of the work is that all processes: changes in numbers or growth for insects should be simulated by the stages of development of their ontogenesis.

Purpose: The purpose of the study is to determine the state policy of the Russian Federation on the Northern and Arctic territories in the 1990s.

Methodology: This is analytical-logical research that has been done through content analysis and documentary and library research.

Result: Results showed that First of all Russia abruptly changed the priorities of its policy to the Far North setting the course to leave the region in all spheres. Dozens of polar expeditions from the USA, Norway, and Germany were sent to the Russian sector of polar lands. Russia itself rapidly turned off its economic presence in the North. “The North Pole-31” (drifting polar station) was stopped for 12 years on June 25, 1991.

Applications: This research can be used for universities, teachers, and students.

Novelty/Originality: In this research, the model of the state policy of the Russian Federation on the northern and arctic territories in the 1990s is presented in a comprehensive and complete manner.

Authors: TEMİZEL Sinem , SEVİM Altuğ Mert
Published: November 2019

A novel unsymmetrical zinc(II) phthalocyanine (ZnPc) (3) with an
alkynyl functional group was prepared by an efficient mixed
statistical condensation of 4-((4-ethynylbenzyl)oxy)phthalonitrile
(1) and 4-(4-tertbutylphenoxy)phthalonitrile (2). FTIR, 1H NMR,
UV-Vis, elemental analysis, and MALDI-TOF were used to characterize
this new compound. Working with different concentrations, the
compound’s aggregation properties were investigated and concluded
that no aggregation tendency has been observed in the studied
concentration range (1.0 x 10-6 M to 1.2 x10-5 M). Fluorescent
quantum yields and lifetimes of the compound were studied and found
to be 0.09 and 0.57 ns, respectively. As a fluorescent quencher,
1,4-benzoquinone was used in the experiments at differing
concentrations in tetrahydrofuran. The kq values showed a close
follow-up to the diffusion control limits, around 1011 s-1 and they
seem to agree with Einstein-Smoluchowski’s approximation for
bimolecular, diffusion-control-including, interactions. For the new
compound, the KSV value was calculated as 27.55, which is lower than
that of unsubstituted ZnPc. The fluorescence of the studied compound
3 was effectively quenched by 1,4-benzoquinone.

Metal Liner Reliability Assessment for BREST-OD-300 Reactor Vessel Accounting for Brittle Fracture and Leaks
Authors: Solonin V.I. , Terekhin A.N. , Shiverskiy E.A.
Published: November 2019

Multi-layer metal-concrete vessel of BREST-OD-300 reactor comprising metal liner that covers internal cavities and ducts has an original design with no known analogues. Due to this, statistical reliability assessment methods, based on operating or testing experience, are not applicable in this case. We propose a method to assess the reliability of the reactor vessel liner taking into account a random nature of loads and mechanical properties affecting brittle rupture and leakage probability. The assessment is based on numerical simulation of postulated defects growth, allowance for the probability of their omission in the control process, and calculation of strength characteristics during operation using finite element models. In our research we took into account such factors as lead coolant and vessel internal component loads, high temperatures and irradiation, low cycle loads. The results of method application revealed the most vulnerable areas of the liner. In addition, findings of research show a high level of reliability of the metal liner of BREST-OD-300 reactor vessel, due to low probabilities of brittle fracture and leaks.

Rabbit is widely used as an experimental animal model in infectious and non-infectious diseases. The haematologic data can be helpful in evaluating the health status of animals over time. The aim of this study was to determine the levels of red blood cells (RBC), white blood cells (WBC) and differential leukocyte counts in 5 nulliparous and 5 multiparous females, i.e. in young and older animals, at mating and at delivery. The values of RBC did not change with age, but WBC and lymphocytes decreased with age, a -33% and a -60% less in multiparous females than nulliparous ones. Monocytes count was double at delivery than at mating. In conclusion, aging on the immune system is manifested as reduction in production of mature lymphocytes and as a result, older females would not respond to immune challenge as robustly as the young ones. Physiological status is only related to production of monocytes.
Growth and Breeding Biology of Female Indian Gerbil (Tatera Indica): Reproductive, Biochemical and Histological Evaluation
Authors: Sandhu Komalpreet Kaur , Singla Neena
Published: November 2019

Average duration of pro-estrous, estrous, met-estrous and di-estrous stages in one oestrous cycle of female Indian gerbil, Tatera indica was found 0.61, 0.38, 0.62 and 1.37 days, respectively with total average duration of one cycle to be 2.99 days. Pairing of cyclic female gerbils with mature males resulted in 88% breeding success within gestation period of 21-24 days. Post-partum estrous was observed immediately after parturition in females not separated from males. Observations on onset of sexual maturity in female pups of seven different age groups (30, 45, 60, 75, 90, 105 and 120 days old) revealed significant increase in body weight and weights of ovary and uterus, plasma level of estradiol and activity of 3â-HSD in ovarian tissue with increasing age. Sexual maturity in female T. indica was attained at age of 3-4 months. It is therefore suggested to apply control measures before they reproduce and cause damage to crops.

Published: November 2019

Clostridium chauvoei, an anaerobic bacterium reported worldwide, is responsible for Black Quarter, a dreadful disease of ruminants. This bacterium produces many toxins responsible for the pathogenesis of the disease. Except for the well-studied virulence factors such as cctA, flagellin andsialidase genes, the exact role of other toxins of C. chauvoei remains unknown. This necessitates studies on the activities of the C. chauvoei toxins and virulence. In the present study, Twin-Arginine Translocation D (TatD) family deoxyribonuclease of the bacterium was selected. The tatD gene C. chauvoei was amplified by PCR and cloned into p-Rham-N-His-SUMO-Kan expression vector, followed by transformation into the E.cloni 10G competent cells. Clones obtained were confirmed by colony PCR. These tatDclones were sequenced and analysed phylogenetically, which revealed the close relationship of C. chauvoei strain to C. isatidis, C. saccharobutylicum, C. botulinum and C. taeniosporum based on tatD sequence analysis. Upon induction of the clones with L-rhamnose,the protein expression was obtained at 42.3 kDa and the same was further confirmed by Western blotting.
