To the question of the design of direct-flow gas pressure regulator direct actions
Authors: Kondrashov Yuriy , Ilyukhin Vladimir , Balyaba Maxim
Published: October 2019

In this paper, issues that need to be considered when designing direct-flow gas pressure regulators of direct action are addressed. A constructive scheme of a piston type gas pressure regulator is presented. Experimental studies of gas pressure regulators of standard sizes DN50 and DN80 at the facility of the existing gas pipeline were conducted, and adjustment of regulators was carried out at the pneumatic stand of the university. The influence of friction forces on the quasi-harmonic low-frequency self-oscillations of the control system is shown. This phenomenon is due to the nature of friction when using rubber and fluoroplastic sealing rings in the moving elements of the regulator and the presence (or absence) of a film of lubricant. This is directly related to transients, stability conditions in transients during regulation due to changes in gas flow.
Dynamic characteristics identification and nonlinear regulator synthesis of a small gas turbine engine based on neural networks
Authors: Makaryants Georgy , Kuznetsov Aleksandr
Published: October 2019

Latterly, neural networks have been used to simulate gas turbine engine dynamics and regulator synthesis. However, little attention has been paid to structure rationalizing of the neural network for identification problems. In addition, neural networks are often used for control issues. Usually these problems are tuning PID regulator coefficients or control in the certain modes. Therefore, it is important to study of the neural network structure dependence on the simulated engine parameter and the neurocontroller synthesis to control the engine in all modes. The neural network architecture was studied for rotor frequency parameter based on the engine tests. In the result neurocontroller was synthesed based on the JetCat P-60 SE engine model taking into account the limitations of the engine fuel consumption. The results allow us to reduce the total time to model engine and synthesys nonlinear controller.

Published: October 2019

Today, this type of drive as pneumatic muscles has wide application. Pneumatic muscle is a one-way drive and has such advantages as the developed force, as well as speed. Pneumatic muscles, compared to pneumatic cylinders, have a non-linear structure that needs to be correctly identified. In this paper, we study the dynamic processes of pressure change in the working cavity of a pneumatic muscle in order to build a mathematical model, which can later be used to develop control systems, where the main actuator is pneumatic muscle, as well as to accurately describe and predict the geometric parameters of pneumatic muscles on pressure of compressed air in the working cavity.
About improvement of the scheme of correction of frequency characteristics of probes for measurement of pulsations of pressure in gte
Authors: Gimadiev Asgat , Bystrof Nikolay , Safin Arthur
Published: October 2019

It is known that pressure pulsations affect the performance of power plants, including a gas turbine engine, reducing the reserve of gas-dynamic stability of the compressor, creating conditions for oscillatory combustion in the combustion chamber. When fine-tuning the engine in the context of the pressure pulsations there is need for measuring means working at extreme temperatures and vibrations. The most acceptable of these means is a probe consisting of a supply waveguide, a pressure pulsation sensor and a corrective element in the form of a long line. However, in the low frequency region there is an uneven amplitude-frequency characteristic of the probe, due to the influence of the reflected pressure waves from the closed end of the long line. It is proposed to install an acoustic RC-filter with resistance equal to the wave resistance of the long line at the output of a long line. The paper theoretically shows that such an improvement of the probe allows to expand the frequency range of measurement of pressure pulsations. The material of the article will be useful for specialists who develop and use tools for measuring pressure fluctuations in extreme conditions, for example, when developing gas turbine engines.

Published: October 2019

Subject. Currently, the use of laser technology is widespread in dentistry in all areas: in surgical dentistry, orthopedic, orthodontics, including aesthetic dentistry. But, despite the widespread use of lasers, in the modern literature not all the advantages of this treatment are described in comparison with traditional methods, including in the treatment of wedge-shaped defects. The most common methods of treating wedge-shaped defects, depending on the progression of the pathology, are reminatory therapy, therapeutic and orthopedic treatment. Thus, the treatment of wedge-shaped defects using the Waterlase Iplus chromium-erbium laser requires a more detailed description.

Goal ― on the example of a specific clinical case, show the features and effectiveness of the Waterlase iplus chromium-erbium laser in the treatment of wedge-shaped defects using modern composite restoration material Filtek Ultimate.

Methodology. A patient with a wedge-shaped defect in the tooth ... was treated with a Waterlase Iplus chromium-erbium laser followed by restoration with a Filtek Ultimate composite material. Laser was used for retraction of the gingival margin, preparation of the walls of the wedge-shaped defect; then etching, bonding and restoration with Filtek Ultimate Flowable and Filtek Ultimate composite materials. Conducted finishing grinding and polishing of the restoration. Single Bond Universal was used as an adhesive system.

Results. The use of the Waterlase Iplus chromium-erbium laser in most cases eliminates the need for local anesthesia, retraction using a retraction thread, and prolonged etching, while ensuring good adhesion of the composite material to dentin and high aesthetics.

Conclusions. Treatment of wedge-shaped defects with the use of a laser is an alternative and less invasive method of treatment compared with traditional methods, allowing you to reduce the time the patient is in the dental chair and make the treatment more comfortable.

Subject. In the practice of a dentist there are patients with complications after dental interventions in the form of post-filling pains and overestimation of fillings, accompanied by intense and constant pain, discomfort and violation of occlusion. Patients turn to the dentist again with complaints of pain in a recently filled tooth, patients note a violation of mastication, loose closing of the jaws, pain in the temporomandibular joint. The subject of this article was the research of the influence of the most common iatrogenic complications in the treatment of caries on the quality of life of patients.

Goal — improving the effectiveness of therapeutic treatment of tooth decay, taking into account the dynamics of indicators of quality of life for patients.

Methodology. A survey was conducted of 25 patients aged 20 to 40 years who came to the dental clinic complaining of post-filling pains, pain in the temporomandibular joint and incomplete closure of the jaw using the SF-36 questionnaire and the Russian-adapted OHRQoL questionnaire. Clinical examination methods included questioning, examination, palpation and percussion of teeth.

Results. After analyzing the results of the adapted OHRQoL questionnaire, it was found that the state of oral health “greatly affects” the quality of life of patients. The average results in a survey of 25 patients amounted to 11.12 points; according to the results of this questionnaire, oral health did not play an insignificant role for any patient. According to the results of the SF-36 questionnaire, quality of life declined on most scales. The largest negative dynamics was noted on a scale of role functioning (RP) of 46 ± 0.03 points out of 100 and vital activity indicators (VT) - 27 ± 0.06 points out of 50. A decrease in the quality of life is caused by a feeling of constant discomfort and pain in the jaw facial area, anxious state of the patient and psychological maladaptation.

Findings. Dental health plays a significant role in maintaining the high quality of life of any person. Dentists need to timely diagnose pathologists, choose the right treatment tactics, avoiding mistakes, and prevent complications.

Subject. Currently, there is an increase in the prevalence of inflammatory and non-inflammatory diseases of the oral cavity, including those combined with various organs and systems. The article addresses the issue of the occurrence of dental diseases in patients with ongoing somatic pathologies, in particular with diseases of the cardiovascular system.

Aim — study of the epidemiological characteristics of dental diseases in patients with diseases of the cardiovascular system.

Methodology. Since 2015, an epidemiological study of 116 patients (87 in the main group and 29 in the comparison group) was conducted. The age range is 40-60 years, in the ratio of 57 % of women and 43 % of men. For each patient, an individually developed map was filled in which the indices of the solid and soft tissues of the oral cavity were noted, as well as microbial and cytological data. Also, each patient completes the Ohip-14 dental questionnaire.

Results. Lesions of caries and its complications in all groups had a similar character. The prevalence of periodontal and oral mucosa diseases is 27.6 % higher in patients with coronary heart disease. Assessing the papillary-marginal-alveolar index (PMA), the level of differences in the groups was 15.5 %. Analysis of the periodontal index (PI) revealed intergroup differences of 16.6 %. The most significant differences were found in the processing of data on the need for treatment of periodontal disease (CPITN), which amounted to 40.7 %. The results of the Schiller—Pisarev test confirmed the propensity for inflammatory processes in the gums in patients with cardiovascular pathology. Evaluating the results of the Kulazhenko test, one can speak of a sharp decrease in the resistance of capillaries in periodontal tissues in cardiac patients, the level of differences was 56.6 %.

Conclusion. Summing up the epidemiological characteristics of the prevalence of the considered dental indicators, one can speak of a greater propensity for periodontal disease and oral mucosa in cardiac patients, which is confirmed by periodontal indices and samples. Also, patients with cardiac diseases are 20.3 % worse than life quality indicators.
INTERACTION OF EMPLOYMENT INSTITUTIONS AND DEVELOPMENT OF MODERN HIGHER EDUCATION SYSTEM IN RUSSIAN SOCIETY
Authors: V. Vodenko Konstantin , S. Sturov Pavel , Yu. Lazareva Galina , V. Kasyanov Valery , A. Dmitrienko Nadezhda
Published: October 2019

Purpose of the study: The study is devoted to the analysis of the specifics of interaction between institutions of employment and development of higher education in modern Russian society. The current arrangement of socio-economic priorities in Russia contrasts with the true economic needs of the labor market and opportunities of the higher education system. In this regard, there is a need to create an integrated system of organizational and institutional mechanisms providing employment regulation and maintaining a balance of interests of the higher education system and the subjects of social and labor relations.

Methodology: The study is conducted on the basis of the principle of interdisciplinarity to research the specifics of interaction of the subjects of social and labor relations in the sphere of higher education. The problem is considered in the context of institutionalism and neo-institutionalism methodology, both in foreign and domestic research traditions. The higher education institution is treated in the context of institutional methodology.

Results: The work is based on the idea that the system of modern higher education is integrated into the subject space of social and labor relations. Thus, the state, the individual, the employer, and higher education institutions are both the concerned parties and the subjects of social and labor relations. But there is a certain disproportion in their interests. The sphere of higher education is characterized by some immanent features that distinguish it from other socio-economic systems that create public goods.  The provision and consumption of educational services involve benefits, both for the individuals and for the entire nation. The mission of higher education and the interests of social and labor relations subjects are closely linked. The interest boundaries of the subjects of social and labor relations necessitate their qualitative characteristics in order to summarize the specifics of satisfaction of their interests.

Applications of this study: The results allow us to conduct a full and detailed study of social and labor relations phenomenon in close relationship with the system of higher education. Within the very framework of neo-institutional theory, it is possible to create a mechanism of management and control for development of employment, social and labor relations.

Novelty/Originality of this study: The research problem of the study is the development of the higher education system in the context of subjective social and labor relations in order to find the solution to the employment problem.

Valoración del apoyo social durante el curso vital
Authors: Lombardo Enrique , Soliverez Corina
Published: October 2019

El apoyo social es un constructo multidimensional que posee una perspectiva estructural y una perspectiva funcional. Desde la perspectiva estructural, se enfatiza la noción de red social, que corresponde a los vínculos que una persona posee y que percibe como significativas. La perspectiva funcional hace referencia a las funciones que desempeña esa red, los apoyos que proporciona y sus efectos en el bienestar del sujeto. Las redes se modifican a lo largo de la vida, en cuanto al tamaño y composición de sus vínculos, lo que puede repercutir en el apoyo que proporciona. Por este motivo, el objetivo de esta investigación fue explorar los apoyos más valorados y necesitados durante el curso vital. Para tal fin, se implementó un diseño no experimental transversal, descriptivo con combinación de metodología cuantitativa y cualitativa. La muestra estuvo constituida por 120 sujetos, de ambos sexos, 30 por grupo de edad (20 a 30, 40 a 50, 60 a 70 y 80 a 90) residentes de la ciudad de Mar del Plata. Al total de la muestra se les administró: un cuestionario de datos sociodemográficos que permitió caracterizar la muestra; y una breve entrevista semi-dirigida que exploró cual es el apoyo más valorado y el que se necesita con mayor frecuencia. Los datos fueron analizados de manera cualitativa mediante la generación de categorías y, posteriormente, de manera cuantitativa, utilizando paquetes estadísticos informatizados para Ciencias Sociales. Los resultados evidencian que el apoyo emocional es el más valorado (72%) y más necesitado (37,5%) en todas las franjas etarias.
Kant’ın Ebedi Barış Teorisinin Özgünlüğü
Authors: YEŞİLÇAYIR Celal
Published: October 2019

Felsefe tarihinde kaleme aldığı
eserlerle önemli çığırlar açmış olan Kant’ın kalıcı barışın sağlanması ile
ilgili önemli fikirler ileri sürdüğü bilinmektedir. Onun kalıcı barışın
sağlanması bağlamında ele aldığı fikirlerde kritik, analitik ve sentezci bir
anlayış benimsediği anlaşılmaktadır. Aynı zamanda onun temel felsefe
karakterinin önemli ölçüde barışla ilgili düşüncelerine yansıdığı dikkat
çekmektedir. Bununla birlikte onun barış teorisi, kendinden önce ortaya çıkmış
barış anlayışları ile kıyaslandığında, bazı özgünlükleri de içinde barındırmaktadır.
Sürekli barışın tesis edilmesinin amaçlanması, negatif barış yerine pozitif
barışın inşa edilmeye çalışılması, barışın temellendirilmesinde din yerine
hukuk argümanına başvurulması ve ulusal/kıtasal barış anlayışından evrensel
barışa geçilmesi onun teorisinin özgünlüğü olarak karşımıza çıkan hususlardır.
Diğer taraftan Kant’ın barış teorisi bağlamında ileri sürdüğü fikirlerin
sonraki dönemlerde popüler olmaya başladığı görülmektedir. XX. yüzyılda
kurulmaya çalışılan uluslararası barış organizasyonları bunun en bariz
örneğidir. Onun barış teorisinin sonradan önemsenmeye başlanması, ele aldığı
fikirlerin özgün olması ile de yakından ilgilidir.

Authors: Machida Daisuke , Yoshida Tohru
Published: October 2019

In this study, we identified the factors that affect the frequency of receiving nonmarket fruit and vegetables (FV). For Survey 1, we conducted a cross-sectional survey using a self-administered questionnaire for men aged 50–74 living in city (A) in Gunma, Japan. Participants were asked questions on FV receiving frequency, FV gardening, social cohesion (4–20 points), and basic characteristics. For Survey 2, a similar survey was conducted for residents aged 20–74 in three areas in city (B) in Gunma, but we included more variables. Ordinal logistic regression models were used for the analysis. In Survey 1, the responses of 243 participants were analyzed. The results showed that the FV receiving frequency was positively associated with non-gardeners and social cohesion. In Survey 2, the responses of 791 participants were analyzed. Vegetable receiving frequency was positively associated with rural and suburban areas, family structure, employment status, and non-farmers. The relationship between receiving frequency and social cohesion was similar to that found in Survey 1. In conclusion, in areas with flourishing FV cultivation, it seems to be easy to obtain FV through the social networks of reception, even for individuals who are not cultivating FV themselves.

Value-of-Information Analysis of a Fracture Prediction Method
Authors: Almansour Abdulaziz , Laubach Stephen E. , Bickel J. Eric , Schultz Richard A.
Published: October 2019

A core-based fracture prediction method is used to illustrate a value-of-information (VOI) decision-analysis protocol to inform completion decisions in tight gas sandstones. The ratio of late host-rock cement to available pore volume (PV), or degradation index, uses petrographic observations of cement distributions in core (including sidewall cores) to predict whether nearby but unsampled fractures (widths > 0.5 to 1 mm) are sealed (nonconductive) or open (conductive). Measurements from four sandstone plays suggest that the index correctly predicts open vs. sealed fractures with an accuracy in excess of 80%. The value added is calculated using Bayesian inference in which the accuracy of the index serves as the likelihood of the prior distribution of open fractures to assess the posterior probability that data represent a useful predictor of producibility. VOI of the prediction method is more than three times the cost to acquire the data. VOI is most sensitive to play-specific geologic and cost parameters including cost to drill, expected revenue from a successful well, cost of completion, cost of acquiring data for the index, and fracture probability distributions. The approach provides a way to value acquiring fracture data and points to a need for zone-specific production data in tight gas sandstones.

Published: October 2019

Background labor pain is one of the leading causes for fear of childbirth. Acupressure is a non-pharmacological pain relief method which showed promising results. Comparing the effect of body acupressure at multiple points and auricular acupressure on the pain and duration of labor, the present study is designed. Methods/Design In a randomized controlled trial, 90 primigravida women who attend for childbirth would be randomly assigned to three groups (interventions: body acupressure and auricular acupressure, control: routine care). In order to determine the allocation sequence with 1:1:1 ratio, the computer-generated 6-block randomization techniques would be used. To hide the allocation, the type of intervention will be written based on the generated sequence and put in opaque enveloped pockets; then, the pockets as well as questionnaires are encoded respectively. The pain score of all the participants would be measured at the peak uterine contraction at the 4cm cervical dilation and at 10 cm dilation based on visual analog scale (VAS). Duration of the active phase of labor in these groups are recorded too. Data are imported into SPSS-16 software. First, normality of the data distribution will be investigated. To compare the labor duration among the research groups, ANOVA would be used, which will be followed, in case of significance, by the Scheffe post-hoc test. Furthermore, Chi-squared test would be used to compare the categorized demographic variables and ANOVA or Kruskal-Wallis tests will be used to compare the quantitative variables in the studied groups. significance level of 0.05 is considered significant. Discussion In this study the effect of auricular acupressure and body acupressure on pain and duration of first stage of labor will be compared.

Published: October 2019

Background—The risk of sudden cardiac death (SCD) is known to be dynamic. However, the accuracy of a dynamic SCD prediction is unknown. We aimed to measure the dynamic predictive accuracy of ECG biomarkers of SCD and competing non-sudden cardiac death (non-SCD).

Methods—Atherosclerosis Risk In Community study participants with analyzable ECGs in sinus rhythm were included (n=15,716; 55% female, 73% white, age 54.2±5.8 y). ECGs of 5 follow-up visits were analyzed. Global electrical heterogeneity and traditional ECG metrics (heart rate, QRS, QTc) were measured. Adjudicated SCD was the primary outcome; non-SCD was competing outcome. Time-dependent area under the receiver operating characteristic curve (ROC(t) AUC) analysis was performed to assess the prediction accuracy of a continuous biomarker in a period of 3,6,9 months, and 1,2,3,5,10, and 15 years using survival analysis framework. Reclassification improvement as compared to clinical risk factors (age, sex, race, diabetes, hypertension, coronary heart disease, stroke) was measured.

Results—Over a median 24.4 y follow-up, there were 577 SCDs (incidence 1.76 (95%CI 1.63-1.91)/1,000 person-years), and 829 non-SCDs [2.55 (95%CI 2.37-2.71)]. No ECG biomarkers predicted SCD within 3 months after ECG recording. Within 6 months, spatial ventricular gradient (SVG) elevation predicted SCD (AUC 0.706; 95%CI 0.526-0.886), but not a non-SCD (AUC 0.527; 95%CI 0.303-0.75). SVG elevation more accurately predicted SCD if ECG was recorded 6 months before SCD (AUC 0.706; 95%CI 0.526-0.886) than 2 years before SCD (AUC 0.608; 95%CI 0.515-0.701). Within the first 3 months after ECG recording, only SVG azimuth improved reclassification of the risk beyond clinical risk factors: 18% SCD events were reclassified from low or intermediate risk to a high-risk category. Long-term, QRS-T angle was the strongest predictor of SCD (AUC 0.710; 95%CI 0.668-0.753 for ECG recorded within 10 years before SCD).

Conclusion—Short-term and long-term predictive accuracy of ECG biomarkers of SCD differed, reflecting differences in transient vs. persistent SCD substrates. The dynamic predictive accuracy of ECG biomarkers should be considered for competing SCD risk scores. The distinction between markers predicting short-term and long-term events may represent the difference between markers heralding SCD (triggers or transient substrates) versus markers identifying persistent substrate.

Background: Most patients with multiple sclerosis (MS) suffer from bladder dysfunction during the course of the disease. This study was conducted to examine the prevalence of these complications among patients with MS.
Methods: This cross-sectional study was performed on 602 patients with MS who referred to the neurology clinics of Kashani and Alzahra Hospitals affiliated to Isfahan University of Medical Sciences, Isfahan, Iran. Multistage random cluster sampling was performed and the informed consent form was signed by the subjects. Then, all the data were collected through interviews using the Lower Urinary Tract Symptom Score (LUTSS) developed in accordance with the definitions presented by the International Continence Society (ICS) and the International Prostate Symptom Score (I-PSS) and DASS-21 questionnaire. The data were analyzed using descriptive and inferential statistical tests in SPSS.
Results: The prevalence rate of lower urinary tract symptoms (LUTS) was 87.6% among all the subjects, with a similar rate among women (88.0%) and men (86.0%). There was a significant difference between men and women in terms of the prevalence of stress urinary incontinence (SUI), intermittent urine flow, hesitancy, straining, and dribbling (P < 0.050). There was no significant difference between women and men in terms of the prevalence of other symptoms (P > 0.050). A significant difference was observed in the degree of LUTS with age, marital status, marriage duration, education, illness duration, clinical course, disability, anxiety, depression, and stress (P < 0.05). Moreover, logistic regression analysis revealed that there was a higher probability of a urinary problems among patients with MS and a high EDSS score [0.67 (0.507-0.903), P = 0.008].
Conclusions: A high prevalence of LUTS was found among patients with MS. There was a higher probability of a urinary tract problem among patients with MS and a high EDSS score. Therefore, it is recommended that the health system take the necessary measures regarding timely detection and treatment of LUTS among these patients in order to prevent secondary outcomes and improve the quality of life (QOL) of patients with MS.

Background: Sucrose (Suc), as the precursor molecule for rubber biosynthesis in Hevea brasiliensis, is transported via phloem-mediated long-distance transport from leaves to laticifers in trunk bark, where latex (cytoplasm of laticifers) is tapped for rubber. In our previous report, six SUT genes have been cloned in Hevea tree, among which HbSUT3 is verified to play an active role in Suc loading to the laticifers. In this study, another latex-abundant SUT isoform, HbSUT5, with expressions only inferior to HbSUT3 was characterized especially for its roles in latex production.Results: Both phylogenetic analysis and subcellular localization identify HbSUT5 as a tonoplast-localized SUT protein under the SUT4-clade (=type III). Suc uptake assay in baker’s yeast reveals HbSUT5 to be a typical Suc-H+ symporter, but its high affinity for Suc (Km = 2.03 mM at pH 5.5) and the similar efficiency in transporting both Suc and maltose making it a peculiar SUT under the SUT4-clade. At the transcript level, HbSUT5 is abundantly and preferentially expressed in Hevea barks. The transcripts of HbSUT5 are conspicuously decreased both in Hevea latex and bark by two yield-stimulating treatments of tapping and ethephon, the patterns of which are contrary to HbSUT3. Under the ethephon treatment, the Suc level in latex cytosol decreases significantly, but that in latex lutoids (polydispersed vacuoles) changes little, suggesting a role of the decreased HbSUT5 expression in Suc compartmentalization in the lutoids and thus enhancing the Suc sink strength in laticifers.Conclusions:Our findings provide insights into the roles of a vacuolar sucrose transporter, HbSUT5, in Suc exchange between lutoids and cytosol in rubber-producing laticifers.

Published: October 2019

Background: Public involvement of citizens in the legislative development process is a constitutional requirement in South Africa. Patient engagement refers to the active involvement of patients in the decision-making processes at multiple levels in the health system. In order for patients to be engaged, they need to be provided with relevant information and an opportunity to be involved in the policy-making process.
Methods: This was cross sectional and quantitative study with descriptive and comparative analyses. Two hundred and forty-four patients from the follow-up clinics at the Internal Medicine Department of Charlotte Maxeke Johannesburg Academic Hospital in the Gauteng Province, South Africa. The patients were interviewed through a structured interview process, using a questionnaire. Descriptive statistics and logistic regression univariate and multivariate analyses were run.
Results: The majority (79.51%) of the participants were not aware of the proposed National Health Insurance (NHI) in South Africa even though process commenced in 2011. Most of the participants (86%) who were aware of the NHI had not received an opportunity to be involved in the policy making process of the NHI. About ninety-one percent of the participants (91.39%) knew that they had a right to be involved in the policy making process of the NHI. The odds of awareness were higher for male (OR: 2.08, 95% CI: 1.11 – 3.9, p value: 0.02) than female participants. The odds of awareness were higher for White (OR: 2.36, 95% CI: 1.06 – 5.26, p value: 0.04) and Indian (OR: 2.76, 95% CI: 0.10 – 7.60, p value: 0.05) participants when compared to Black participants. The odds of awareness were higher for retired (OR: 3.13, 95% CI: 1.35 – 7.25, p value: 0.008) than unemployed participants.
Conclusions: Without the awareness and information about the NHI, patients are not equipped to be involved in the NHI policy process in a meaningful way.

BackgroundThe white-eared opossum (Didelphis albiventris) is widely distributed throughout Brazil and South America. It has been used as an animal model for studying different scientific questions ranging from the restoration of degraded green areas to medical aspects of Chagas disease, leishmaniasis and resistance against snake venom. As a marsupial, D. albiventris can also contribute to the understanding of the molecular mechanisms that govern the different stages of organogenesis. Opossum joeys are born after only 13 days, and the final stages of organogenesis occur when the neonates are inside the pouch, depending on lactation. As neither the genome of this opossum species nor its transcriptome has been completely sequenced, the use of D. albiventris as an animal model is limited. In this work, we sequenced the D. albiventris transcriptome by RNA-seq to obtain the first catalogue of differentially expressed (DE) genes and gene ontology (GO) annotations during the neonatal stages of marsupial development.ResultsThe D. albiventris transcriptome was obtained from whole neonates harvested at birth (P0), at five days of age (P5) and at ten days of age (P10). The de novo assembly of these transcripts generated 85,338 transcripts. Approximately 30% of these transcripts could be mapped against the amino acid sequences of M. domestica, the evolutionarily closest relative of D. albiventris to be sequenced thus far. Among the expressed transcripts, 2,077 were found to be DE between P0 and P5, 13,780 between P0 and P10, and 1,453 between P5 and P10. The enriched GO terms were mainly related to the immune system, blood tissue development and differentiation, vision, hearing, digestion, the CNS and limb development.ConclusionsThe elucidation of opossum transcriptomes provides an out-group for better understanding the distinct characteristics associated with the evolution of mammalian species. This study provides the first transcriptome sequences and catalogue of genes for a marsupial species at different neonatal stages, allowing the study of the mechanisms involved in organogenesis.
