Spontaneous rupture of unscarred uterus secondary to placental percreta in the third trimester of pregnancy after IVF and embryo transfer: a case report
Authors: Zhou Yanzhen , Zheng Xinye , Chen Li
Published: December 2021

Background: It is very rare for a young woman to experience spontaneous rupture of an unscarred uterus. Clinicians usually have a low clinical index of suspicion and may underestimate the possibility of a uterine rupture, leading to neonatal mortality in particular circumstances. We presented an incidence of spontaneous rupture of an unscarred uterus induced by placenta percreta in the third trimester of pregnancy. Case: A 27-year-old woman with an unscarred uterus, at a gestation of 31 weeks and 4 days, was presented with the right epigastric pain and vomiting after 10 hours of admission. Relevant symptomatic treatment was prescribed but did not release the related symptoms. Furthermore, an emergent exploratory laparotomy and cesarean section were conducted after the presence of hypotension and abnormal fetal heart rate, during which a spontaneous rupture of an unscarred uterus occurred, resulting in stillbirth and intraperitoneal hemorrhage. The pathological examination confirmed placental percreta as the cause of the rupture. Conclusions: IVF-ET may be a risk factor of UR and placental percreta. Potential uterine rupture should be considered for pregnant women receiving IVF-ET when they complain of abdominal pain and abnormal fetal heart rate. This case highlights the importance of identifying the risk factors for placental percreta so that patients at risk would benefit from an antenatal detection of abnormal placentation.

Authors: Baek Jong Chul , Jo Hyen Chul , Lee Seon Mi , Park Ji Eun , Cho In Ae
Published: December 2021

Background: Premature ovarian insufficiency (POI) is defined as the onset of a menopausal state prior to 40 years of age. Of the various causes of POI, genetic abnormalities account for 10.8% of all cases, which can be categorized into either chromosomal or gene anomalies. Chromosomal abnormalities of the isochromosome Xq [i(Xq)] type have been recognized as common causes of POI. Cases: A 16-year-old female presented with secondary amenorrhea that had persisted for one year. Her physical examination was unremarkable, including a height of 158 cm and the presence of secondary sexual characteristics. Her serum level of follicle-stimulating hormone was elevated (66 mIU/mL), whereas her estradiol and anti-Müllerian hormone levels were decreased (<10 pg/mL and 0.02 pg/mL, respectively). Conventional cytogenetic analyses of a peripheral blood sample showed the karyotype of 46,X,ider(X)(q28)i(X)(q10). Conclusions: We describe a novel chromosomal structural abnormality of the i(Xq) type that is associated with a diagnosis of POI.
Transformation of the Ethiopian Political Elite and the Armed Conflict in Tigray: from Driving Predecessors out to De-Escalation?
Authors: Loshkariov Ivan , Kopytsev Ivan
Published: December 2021

In the article the authors consider elite dimension of the conflict in Tigray. Conducting the analysis of intra-elite processes allows both to find out the roots and to estimate the consequences of the most fast-moving conflict in the Horn of Africa. The research consists of five conceptual parts, which are preluded by a short description of the run of events. In the first part the conflict potential which takes its roots in 1994-2018 is explained. It starts with the basic notion that ethnic lines predetermine formation of elites in Ethiopia. Then the study shows that one of the main causes for the dispute which has severely divided political elites was the hegemony of the TPLF in government institutions. The second part refers to the transit of power. Here the point under consideration is redistribution of resources and particular strategies adopted by polarized elites. The analysis demonstrates that Abiy Ahmed and his allies did their best to deprive the TPLF leaders of power and economic resources. The TPLF resorted to ethnic mobilization while their rivals tried to break the unity of Tigrayans through stressing the existence of a class conflict. The third and the fourth chapters focus on the investigation of federal elites’ and «tigrayan clan’s» current positions respectively. In conclusion, the authors structure their findings and estimate the perspectives of inter-elites consensus. The research provides three important conclusions. Firstly, the roots of the conflict led to the formation of «action-response» cycles which was the basis for a rapid development and escalation. Secondly, the ongoing war even consolidates ruling elites in their fear of the TPLF. Finally, de-escalation and negotiations may become possible amid internal disputes in the Prosperity Party.

Published: December 2021

In the modern world, the requirements for the quality and safety of food products are constantly increasing. In order to make a profit and survive in a tough competition ring, manufacturers often come up with complex food compositions that provide a long shelf life and a wide range of temperature corridors during storage, which entails a decrease in the quality of life of people, an increase in the level of morbidity and risks associated with a threat to life. The interest of consumers in obtaining knowledge in the field of food quality and safety has grown significantly, as well as the possibility of obtaining this information through the Internet. All this has led to the imposition of more stringent requirements for both consumers and state regulatory bodies, to confirm food safety. In matters of ensuring and managing the quality of food products, the organization of product traceability plays a key role.This article discusses the main tasks of introducing state information systems of traceability of the GIS «Mercury» and «Honest Sign», as well as the problems faced by business systems when integrating these systems into operational activities.

Published: December 2021

Hakikat manusia adalah sebagai gagasan atau konsep yang mendasari manusia dan eksistensinya di dunia. Eksistensinya berhubungan dengan masa lalunya untuk menjangkau masa depan dan untuk mencapai tujuan dalam hidupnya. Manusia berada dalam perjalanan hidup, perkembangan dan pengembangan diri namun, manusia disini belum tuntas mewujudkan dirinya sebagai manusia. Pendidikan pada dasarnya adalah upaya untuk memanusiakan manusianya. Manusia sudah dibekali berbagai potensi untuk mampu menjadi manusia. Kemampuannya itu hanya dapat dilakukan setelah kelahirannya dalam perkembangan menuju kedewasaanya dan tidak di bawa sejak kelahirannya. pembangunan masyarakat menyiratkan keterkaitan antara pengertian pembangunan dan pengertian masyarakat. Pembangunan masyarakat berarti upaya membangun masyarakat atau sekumpulan orang, dengan titik berat pada pembangunan masyarakat itu sendiri, atau pada aspek manusianya. Secara lebih tegas pengertian ini terungkap dalam definisi menurut UNESCO (dalam Poostchi, 1986: 1),yang menyatakan bahwa tujuan dan sarana pembangunan bukan membangun benda melainkan membangun manusia.
The emerging science of microdosing: A systematic review of research on low dose psychedelics (1955 – 2021)
Authors: Polito Vince , Liknaitzky Paul
Published: December 2021

The use of low doses of psychedelic substances (microdosing) is attracting increasing interest. This systematic review summarises all empirical microdosing research to date, including a set of infrequently cited studies that took place prior to prohibition. Specifically, we reviewed 44 studies published between 1955 and 2021, and summarised reported effects across six categories: mood and mental health; wellbeing and attitude; cognition and creativity; personality; changes in conscious state; and neurobiology and physiology. Studies showed a wide range in risk of bias, depending on design, age, and other study characteristics. Laboratory studies found changes in pain perception, time perception, conscious state, and neurophysiology. Self-report studies found changes in cognitive processing and mental health. We review data related to expectation and placebo effects, but argue that claims that microdosing effects are largely due to expectancy are premature and possibly wrong. In addition, we attempt to clarify definitional inconsistencies in the microdosing literature by providing suggested dose ranges across different substances. Finally, we provide specific design suggestions to facilitate more rigorous future research.
Predicting Fraction and Algebra Achievements Online: A Large-Scale Longitudinal Study Using Data from an Online Learning Environment
Authors: Spitzer Markus , Moeller Korbinian
Published: December 2021

Background: Mastering fractions seems among the most critical mathematical skills for students to acquire in school as fraction understanding significantly predicts later mathematic achievements, but also broader academic and vocational prospects. As such, identifying longitudinal predictors of fraction understanding (e.g., mastery of numbers and operations) is highly relevant. However, almost all existing studies identifying more basic numerical skills as predictors of fraction understanding rest on data acquired in face-to-face testing—mostly in classrooms. Objectives: In this article, we evaluated whether results obtained in these previous studies generalized to data from the curriculum-based online learning environment Bettermarks for mathematics used in schools in the Netherlands. Methods: We considered data from more than 5,000 students who solved over 1 million mathematical problem sets on basic mathematical skills, fractions, but also algebra. Results and Conclusions: In line with previous findings, we found that fraction understanding was predicted significantly by more basic mathematical skills. Our analyzes also indicated that algebra achievement was predicted significantly by fraction understanding beyond influences of more basic mathematical skills. Implications: Together, these findings generalized previous results based on face-to-face testing to the context of data from online learning environments and thus, indicate that data from such large-scale online learning environments may well qualify to provide significant insights into the hierarchical development of mathematical skills.
Numerical origins: The critical questions
Authors: Overmann Karenleigh A.
Published: December 2021

Four perspectives on numerical origins are examined. The nativist model sees numbers as an aspect of numerosity, the biologically endowed ability to appreciate quantity that humans share with other species. The linguistic model sees numbers as a function of language. The embodied model sees numbers as conceptual metaphors informed by physical experience and expressed in language. Finally, the extended model sees numbers as conceptual outcomes of a cognitive system that includes material forms as constitutive components. If numerical origins are to be found, each perspective must address one or more critical questions that will require working across discipline boundaries.
What’s in an Occupation? Investigating Within-Occupation Variation and Gender Segregation Using Job Titles and Task Descriptions
Authors: Martin-Caughey Ananda
Published: December 2021

Occupations have long been central to the study of inequality and mobility. However, the occupational categories typical in most U.S. survey data conceal potentially important patterns within occupations. This project uses a novel data source that has not previously been released for analysis: the verbatim text responses provided by respondents to the General Social Survey from 1972 to 2018 when asked about their occupation. These text data allow for an investigation of variation within occupations, in terms of job titles and task descriptions, and the occupation-level factors associated with this variation. I construct an index of occupational similarity based on the average pairwise cosine similarity between job titles and between task descriptions within occupations. Findings indicate substantial variation in the level of similarity across occupations. Occupational prestige, education, and income are associated with less heterogeneity in terms of job titles but slightly more heterogeneity in terms of task descriptions. Gender diversity is associated with more internal heterogeneity in terms of both job titles and task descriptions. In addition, I use the case of gender segregation to demonstrate how occupational categories can conceal the depth and form of stratification.

Authors: Bhagat Indramani
Published: December 2021

The fungus Sclerotium rolfsii is one of the most destructive diseases in tea growing areas of the world. Effective and efficient management of cash crop disease is generally achieved by the use of synthetic pesticides. These pesticides are known to pollute the environment, soil and water causing deleterious effects on human health and biosphere. A search for an environmentally safe and economically viable strategy for the control of the disease has led to an increased use of plant based products in agriculture. Hence, in the present investigation, efficacy of antifungal effect of Azadirachta indica and Catharanthus roseus were tested in vitro against S. rolfsii.

In this study, the effects of auxin (IBA, NAA), explants, and culture conditions (light/dark) on adventitious root induction of Codonopsis javanica were investigated. The results showed that dark conditions were more suitable for adventitious root induction than light conditions. All three types of explants (internodes, leaves, and nodes) induced adventitious roots, and the appropriate concentration of auxin was 0.5 mg/l IBA. After 4 weeks of incubation under dark conditions, the rooting percentage and number of roots/explant of internode, leaf, and node segments on media supplemented with 0.5 mg/l IBA were 100% and 33.87 roots, 97.78% and 23.48 roots, 100% and 25.20 roots, respectively. These adventitious roots were analysed for the presence of alkaloids, carbohydrates, saponin, fixed oils and fats, phenol, flavonoids, gum, and mucilage. The total polysaccharide content, total phenolic content, and the antioxidant activity (IC50) of C. javanica adventitious root biomass were 16.98%, 1.876 (mg GAE/g DW), and 2.44 (mg/ml), respectively. These results indicate that the adventitious roots of C. javanica contain bioactive compounds, which can be used as a material source for multiplication in large-scale systems.

Since 2010, 49 cases of liver transplants from brain-dead donors were performed at Viet Duc University Hospital. This study is a descriptive cross-section cohort study with a combined analysis of retrospective and prospective occurrences of a series of cases of liver procurement from brain-dead donors in Viet Duc University Hospital from March 2010 to March 2020. The results of this study showed several features: the average age of the brain-dead donors was 29.8±10.9 (18-69), donors were mostly male (7.17/1, 87.8%), and the main cause of brain death was head trauma. Clinically, 40.8 and 63.3% of the subjects were hypothermic and diagnosed with diabetes insipidus, however, the subjects were all well resuscitated before procurement. Therefore, haemodynamic indices and temperatures were maintained at stable levels and there was no statistically significant difference. In subclinical aspects, haemoglobin and platelet levels decreased significantly but remained within the target criteria during resuscitation while blood sodium levels increased significantly during resuscitation when compared with levels at the time of admission (p<0.001) thus corresponding to diabetes insipidus. In general, 44.90% of donors were within the ideal standard, and in the extended standard group, the highest rate was electrolyte disorders (32.65%). In conclusion, there are many variations in clinical and paraclinical body signs as well as homeostasis in the brain-dead donors. Of these signs, the most prominent were changes in haemodynamics, temperature, urine output, complete blood count, blood clotting, and blood sodium levels. These are all factors that are included in the criteria to consider the selection of a liver donor.

Vibrio parahaemolyticus is the main causative agent of acute hepatopancreatic necrosis disease (AHPND) in shrimp. This study aimed to investigate how shrimp extracts affect the growth and virulence of an AHPND-causative strain known as V. parahaemolyticus XN9. To this end, the bacteria was cultured in media containing 3% extract of each of five shrimp types and their growth kinetics were compared against that from bacteria grown in brain-heart infusion (BHI) media. Eight-hour growth curves were constructed using the plate-counting method. The activity of five extracellular enzymes that contribute to bacterial virulence was examined using the agar-based method. The results showed that V. parahaemolyticus XN9’s growth was strongly enhanced in all five shrimp extract media with the highest increase (25% greater than the BHI medium) found in the giant tiger prawn extract. Additionally, all the shrimp extracts boosted the extracellular enzymatic activity of V. parahaemolyticus XN9, although to different extents. In summary, the shrimp extracts, particularly that from the prawns, not only promoted the viability and growth of V. parahaemolyticus XN9 but also its extracellular enzymatic activities.

Air quality in megacities has been a pressing concern of environmental managers and scientists for decades. Indeed, particulate matter (PM), especially PM2.5, is considered a dangerousparticle that is harmful to human health. The current sparse monitoring network in Ho Chi Minh city (HCMC) does not accurately reflect the spatial distribution of fine particles in ambient air. Therefore, this research examines the relationship between ground-based station data and aerosol optical depth (AOD) imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Terra/Aqua satellite to establish a PM2.5 distribution map of HCMC. PM2.5 concentration values monitored from two ground stations were collocated by time and space with Terra/MODIS AOD data from the period of 2016-2020. Pairs of values were checked for correlation and then fit to several regression functions. The most suitable function was chosen to simulate the quantified PM2.5distributions in the study area. A high correlation between PM2.5 concentrations and AOD at the wavelength of green light (R2=0.810) was found with a linear regression model. The results showed that the highest concentration of PM2.5 was in February, and the mean value was higher than QCVN 05:2013 (32.5 μg/m3compared with 25 μg/m3, annual mean). These results support the need for essential air quality monitoring in HCMC.
Des textes identitaires plurilingues pour stimuler l’engagement dans l’écriture d’élèves immigrants allophones en situation de grand retard scolaire au secondaire
Authors: Maynard Catherine , Armand Françoise
Published: December 2021

Learning to write in a second language is an enormous challenge, particularly for undereducated allophone immigrant students. In this context, interventions fostering students’ engagement in writing appear to be a promising way to contribute to their learning process ( Cummins, 2009 ). Engagement in writing would be promoted by taking into account students’ multiliterate repertoires and by implementing meaningful learning contexts ( Armand, Lê et al., 2011 ). In this study, which was carried out in 12 secondary school classes for newcomers in Quebec (Canada), we assessed the effects of an intervention based on these foundations and aimed at the production of plurilingual identity texts ( Cummins et Early, 2011 ), supported by plurilingual drama workshops ( Équipes ÉRIT et ÉLODiL, 2013 ). The effects of this intervention on students’ engagement in writing were documented through participant observations and individual interviews with a sub-sample of 48 students. Results show that the production of plurilingual identity texts, especially when supported by plurilingual drama workshops, contributes more to students’ engagement in writing than traditional teaching practices used in a control group, both on an affective and cognitive level.
‘Not more democratic, but more moral’: Tocqueville on the suffrage in America and France
Authors: Englert Gianna
Published: December 2021

Tocqueville has been portrayed as a “strange liberal” for his singular defenses of individual liberty. This essay highlights an overlooked instance of Tocqueville’s distinctiveness by analyzing his thoughts on suffrage, which placed him at odds with his French liberal contemporaries. It uncovers Tocqueville’s attitude toward universal suffrage in America and his critiques of a capacitarian suffrage in France. I argue that Tocqueville articulated his hope not for a “more democratic, but for a more moral” electoral law during most of the July Monarchy, aiming to transcend existing debates over the extent of the electorate or the capacité politique of the individual elector. By arguing for Tocqueville’s singularity on the suffrage, this essay brings to light both his departures from the thought of the liberal Doctrinaires and his reflections on the particular character of democracy in France.

The efficiency of proprioceptive training in preventing injuries to team athletes: A systematic review
Authors: Manojlović Marko
Published: December 2021

The aim of this systematic review was to evaluate the effectiveness of proprioceptive training in the prevention of lower extremity injuries, especially the ankle and knee joint, in team athletes. PRISMA recommendations were applied for this research. PubMed, ScienceDirect, and BioMed Central were used to identify relevant studies. The methodological quality of studies was assessed using the Physiotherapy Evidence Database-PEDro scale. Only 7 research met the eligibility criteria, and their outcomes were presented. Proprioceptive training has been shown to be very effective in preventing ankle injuries, especially in recurrent ankle sprains. However, in 3 of 4 studies lacked the effects of proprioceptive training in the prevention of knee and ACL injuries. Based on the results of the analyzed research, I can conclude that proprioceptive training is a very effective training tool in the prevention of ankle sprains in the population of team athletes, but proprioceptive training is not sufficient as the only training component in preventing knee injuries.

Published: December 2021

Background: Patient-prothesis mismatch (PPM) is a serious potential complication following surgical aortic valve replacement (SAVR). If it develops, valve-in-valve transcatheter aortic valve replacement (TAVR) is a reasonable therapeutic option. However, there is low evidence on the management of small degenerated surgical bioprosthetic valves, not prone to balloon-valve fracture (BVF). Case Presentation: This case report presents a successful valve-in-valve TAVR in acute heart failure due to degenerative surgical bioprosthetic valve Trifecta (21 mm) that is not susceptible to BVF. Standard preparation for transfemoral TAVR with a self-expandable valve was conducted, including the over-the-wire pacing. Thereafter, a successful valve-in-valve primary implantation of the self-expanding, supra-annular valve Evolut R 26 (Medtronic™) has been achieved. Follow-up at 3 months showed mild paravalvular leak in the region with clinical and heart function improvements of the patient. Follow-up echocardiographic parameters showed the reduction of anterograde flow impairment and improved effective orifice area (~0.85 cm2/m2). Conclusion: In conclusion, supra-annular valve-in-valve TAVR is a potential therapeutic option for PPM of small degenerated surgical bioprosthetic valves which are not prone to BVF.
A study on the effect of blade inlet angle, attack angle and the diameter ratio on the efficiency of a Banki Mitchell turbine
Authors: NIYIGENA Hırwa Jean Paul
Published: December 2021

In the present work, a theoretical investigation is presented on how the efficiency of a Banki Mitchell turbine is affected by its design parameters. With the help of general formulation of the control volume theory to the equation of the moment of momentum in the turbine’s runner and considering all assumption regarding the properties of the flow and the design geometry of the runner, a mathematical model has been developed. The water discharge through the turbine is considered incompressible, non-viscous, homogenous and steady flow; The loss due to shock on the inner and outer surface of the runner as well as leakage losses are neglected. As results of the present study, the behaviour of hydraulic efficiency was determined when varying the angle of attack, the blade entry angle as well as the runner diameter ratio, indicating their appropriate values in each different scenario. In this paper critical relationships between design parameters have been disclosed and therefore analysed and simulated using Simulink MATLAB. Furthermore, it was mentioned that for a better performance, the exit angle of the blade should be 90°. At length, an expression was given estimating the turbine’s efficiency at various operating conditions and for calculating the energy contribution per stage, respectively.
COMBINATORIAL RECONSTRUCTION OF TWO-DIMENSIONAL WORDS IN THE HYPOTHESIS SHIFT 1
Authors: Ulyanov M.
Published: December 2021

The article considers the formulation of the problem of reconstruction of two-dimensional words by a given multiset of subwords, under the hypothesis that this subset is generated by the displacement of a two-dimensional window of fixed size by an unknown two-dimensional word with a shift 1. A variant of the combinatorial solution of this reconstruction problem is proposed, based on a two-fold application of the one-dimensional word reconstruction method using the search for Eulerian paths or cycles in the de Bruyne multiorgraph. The efficiency of the method is discussed under the conditions of a square two-dimensional shift window one having a large linear size.

Intravitreal injections (IVI) have revolutionized management strategies for many disorders, e.g., age-related macular degeneration (AMD), diabetic macular edema, retinal vein occlusion, choroidal inflammatory diseases, and pathologic myopia. Over the last two decades, exponential growth in the rate of IVIs has been seen worldwide. Primary therapeutic modalities include the courses of periodic injections to achieve and maintain the desired effect. Studies on the effects and neuroprotective role of vascular endothelial growth factor (VEGF) and agents blocking its action in various organs and tissues on the retina have demonstrated some differences in the outcomes and their interpretation which potentially affect IVI management strategy and treatment efficacy. Understanding the results and ocular changes in response to therapy (particularly in patients with glaucoma) requires special attention. A predicted increase in life expectancy and the number of patients with glaucoma suggests that the number of patients with several eye diseases who require IVIs will inevitably increase. In addition, some studies evaluate glaucoma progression after IVIs. Considering a lack of relevant data on long-term adverse effects on IOP level and cup area, and improvement of visual functions, IVIs are regarded as a safe treatment modality in patients with primary open-angle glaucoma (POAG) and ocular comorbidities that require IVIs. Keywords: intravitreal injections, glaucoma, vascular endothelial growth factor, retinal ganglionic cells, retinal nerve fiber layer, intraocular pressure, optical coherence tomography, optic disc.

Published: December 2021

Community service is one of the Tri Dharma of Higher Education in order to involve universities to solve problems that exist in the community, one of which is through student work activities (KKM). The increasing trend of COVID-19 virus cases in Indonesia has resulted in this year's KKM activities being carried out online. COVID-19 is a pandemic outbreak that has hit various countries and is a form of concern for the public. Currently, there are many variants of the COVID-19 outbreak mutation that result in an increased risk of spread. Many health facilities in Indonesia are currently at full capacity, so people who experience mild COVID-19 symptoms are directed to undergo independent isolation at their respective homes. The 37 UNTIRTA Thematic KKM group held a webinar work program on COVID-19 socialization and self-isolation. The conclusion of this activity is the implementation of a COVID-19 webinar and self-isolation targeting the general public with a speaker from dr. Taufik Nugraha, Doctor of the Cikuya Health Center and the presence of representatives of Pasanggrahan Village and the Sub-district Head of Solear. The purpose of this work program is to educate the general public regarding COVID-19 and the procedures for proper self-isolation. The results of the webinar have provided additional understanding to the community, especially the residents of Pesanggrahan Village, Solear District, Tangerang Regency. It is recommended that village government officials do not get bored educating their people about Covid 19.
