Growth and Morphological Characteristics of Asp376Glu Mutation in AHAS-Resistant and-Susceptible Yellow Burrhead (Limnocharis flava (L.) Buchenau) Populations
Authors: Zakaria Norazua , Ahmad Hamdani Muhammad Saiful
Published: December 2022

Herbicides are considered the most effective weed management approach in the world. Acetohydroxyacid synthase (AHAS, EC 2.2.1.6) is widely used due to its advantages in crop selectivity, effectiveness to control broad-spectrum weeds and low mammalian toxicity has become one of the most popular herbicides used by farmers. The overreliance on the same herbicides over the years to control the weeds led to the evolution of herbicide resistance by several weed species, including Limnocharis flava (L.) Buchenau is among the resistant weed species in the rice fields of Southeast Asia. This species has been reported to develop resistance to bensulfuron-methyl (AHAS inhibitor). This study aims to determine the morphological characteristics of susceptible and resistant L. flava populations by comparing the growth and development of the plants. Results showed that the Asp-376-Glu mutation in the AHAS gene of the L. Flava-resistant population has exhibited significantly stronger (dry weight) or no significantly different impacts as compared to the susceptible population in the fresh weight, height, epicuticular weight, and leaf area. The insignificant differences were observed in the leaf structure and morphology of R and S plants which appears to have no possible fitness cost in the R population. This is the confirmation of the differences between the AHAS-resistant and susceptible populations that emphasizes the morphological characteristics that is crucial for herbicide application for controlling L. Flava populations.

Published: December 2022

The work is devoted to the solution of an actual scientific task in the field of civil protection, namely, the analysis of methods of researching thermal damage to structures due to fire at critical infrastructure facilities, with the aim of further developing a model for preventing terrorist emergencies at critical infrastructure facilities of Ukraine. This work is a continuation of the cycle of previous works on the development of structural, logical and mathematical models for managing an emergency situation of a terrorist nature at an object of the critical infrastructure of Ukraine, which is protected, which are intended for the development and constant implementation of procedures of an organizational and technical nature that ensure the safety of the object. Further research will be directed to the development of appropriate mathematical models and conducting field experiments, performed using a specially designed laboratory facility to determine the reliability of the latter, comparing theoretical and practical results. Today, there are a number of physical and chemical methods that can be used to reliably determine the signs of a fire and establish the causes of fires. Almost all of them are based on the ability to register structural transformations that occur under the influence of high temperatures and directly from the flames of fires. The problem of obtaining objective data, necessary to establish the center of the fire and the ways of the spread of combustion, remains extremely relevant, especially in cases where it is impossible to examine the objects of the physical environment due to their destruction and removal from the fire site. The task of determining the burning conditions in different fire zones and identifying the focal signs of a fire in yours were not set and solved. The analysis of the electrical resistance of the soot layer makes it possible to investigate the sooting of the place at the site of the fire and, thus, to identify the ways of propagation of the main convective flows and the focal zone. Keywords: emergency, critical infrastructure object, thermal damage.

ERGONOMICS OF PROFESSIONAL RISKS MANAGEMENT
Authors: Yavorska O. , Arkhirei M. , Sharovatova O. , Borovytskyi O.
Published: December 2022

In the modern working environment, the performance of professional tasks mostly depends on the physiological and cognitive abilities of employees, adaptive and mental processes. From these abilities and processes depend on information processing. Emphasized attention is placed on the fact that acceptable working conditions, high work productivity and a high level of well-being of employees are interconnected elements. Therefore, it is important to manage the conditions of cognitive and physiological stress in order to reduce their harmful consequences for individual employees, teams, organizations, etc.
To improve the effectiveness of risk management, a four-step approach is proposed, which involves accounting for occupational hazards, dangerous and harmful occupational factors at the workplace; providing the opportunity of any employee to contact the group of rapid response to hazards in case of occurrence or change of dangerous and harmful occupational factors, growth of occupational risks, appearance of new hazards, etc. during the work shift; introducing a discussion with justification of preventive and protective actions to reduce professional risks; application of measures for the prevention of dangerous situations (conducting supervision, audits and self-assessment of the activities of employees at workplaces).
Systematicity is the main principle of ergonomics used to develop an algorithm for the step-by-step implementation of the process of managing professional risks. It`s consists of defining as a complete system - the set of all components of the labor activity of employees, which would reduce the impact on the physiological and cognitive potential of the employee.
Forms of a hazard guide, a hazard notification card and a safety audit report have been developed. It will reduce the time to learn the specified procedures due to a conscious attitude to one's own activities at the workplace.
Reasonable measures to increase the effectiveness of professional risks management based on the step-by-step performance of certain actions by employees are oriented to increasing awareness of safety at the workplace.
Keywords: risk, management, ergonomics, preventive measures, cognitive stress.

Authors: Teliura N. , Sorokina K. , Lomakina O. , Lekashevych D.
Published: December 2022

Approaches to substantiation of innovative ecological solutions to reduce the production impact on the environment have been studied. Ways to increase environmental safety on the basis of sustainable development through a well-founded complex selection of innovative solutions are proposed. Based on the method of analysis of hierarchies (MAI), a methodical approach for determining the priority innovative ecological solutions. The developed approach makes it possible to involve experts in environmental, urban planning, social, and economic direction of municipal management bodies of a specific settlement, industrial, residential, and military facilities.
According to the developed approach, criteria formulated as influencing groups of factors. Relevant experts, relying on various types of information (data of direct measurements, statistical and predictive estimates) on the specific purpose and innovative ecological solutions, give their own judgments regarding the priority of the advantages of the specified criteria. Expert judgments are processed according to the formal procedure of the MAI, which is implemented on a computer, and is the basis for decision-making when choosing the innovative ecological solutions in specific conditions.
The multi-criteria hierarchical structure of innovative ecological solutions is represented by a sequence of actions that include the following stages: development of elements of a methodical approach; verification of the consistency of the proposed hierarchical structure for determining priority technologies based on the input data of several objects of settlements; obtaining data on the priority of innovative ecological solutions for implementation on these objects. The advantages of the proposed methodical approach should include the possibility to link to a single algorithm for the justification of the required decision data that differ both in their content (ecological, biological in terms of higher aquatic plants, urban planning, social and economic) and in the form of presentation (data of direct measurements, statistical and predictive estimates).
Keywords: environmental safety, balanced nature management, system approach, technologies, tools and ecological and economic aspects of environmental protection activities, environmental quality, processing of eco-data, regulatory framework, sustainability.
PRINCIPLES OF ENVIRONMENTAL SAFETY MANAGEMENT OF URBOSYSTEMS UNDER THE CONDITIONS OF CLIMATE CHANGE
Authors: Reshetchenko A. , Vorobiov O.
Published: December 2022

Methods of environmental safety management as a component and integral part of the toolkit of sustainable development are analyzed. The use of a system-ecological approach is proposed on the example of monitoring data of water consumption in the Lopan River with the recommendation of environmental protection and ecologically safe management solutions. According to the results of the calculations, it was found that the average volume of the Lopan river flow decreased from 86.5 in 1980 to 39.4 in 2020. The peculiarities of the implementation of nature-oriented technical and economic solutions are the gradual transformation of urbanized systems into an ecologically safe space, for the implementation of which methods of system analysis are used. It is the systemic approach that makes it possible to understand any phenomena of life in relation to various levels of its organization and the environment.
The analysis of the tasks for the implementation of the 13th CST "Mitigation of the consequences of climate change" summarizes the statement regarding the need to transition to an ecological economy, green energy and support the sustainability of society, which is highlighted in the general concept of sustainable development - a violation of the balance between the economic and ecological interests of society negatively affects the quality of society's life. Thus, the effectiveness of existing measures in ensuring sustainable development should be evaluated through the dependence of indicators of economic growth and the quality of the environment. Mitigation measures to reduce the impact of climate on the natural environment should include the decarbonization of energy, the reduction of greenhouse gas emissions in the land use and forestry sector, and the implementation of a regulated state policy on mitigating the consequences of climate change, compliance with the Environmental Security Strategy and adaptation to climate change by 2030, approved by the Cabinet of Ministers of Ukraine in 2021.
Keywords: environmental safety, sustainable development, urban systems, climate change, management decisions, monitoring, river flow, system-ecological approach.
PARAMETERS RATIONALIZATION OF THE THIN-WALLED ANCHORED RETAINING WALLS
Authors: Kalmykov O. , Binkevych K. , Buldakov O.
Published: December 2022

One of the priority areas of theoretical research in the field of building structures is to reduce their own weight at a given resource - rationalization. There is a certain number of building structures in which the form and nature of the external load are interdependent. The most striking representative are the structures that perceive lateral pressure from bulk material - retaining walls. From the above review of modern scientific research aimed at finding rational parameters of retaining walls, it follows that the authors, as a rule, describe the cantilever retaining wall by a finite number of parameters and the reduction of its own weight or cost of the structure was taken as the target function. In this case, the load on the structure does not change.
The idea underlying this work is that the structure of the retaining wall and the soil backfill, which holds it, is considered as a single system. In this system, the configuration of the structure determines the nature and magnitude of lateral pressure distribution. The sequence of actions to solve the problem of searching for a rational configuration of the structure leads to the division of the curved foam wall into a finite number of linear sections. The anchor support is represented in the form of an additional concentrated force applied at the anchor fixing point. In the work the dependences between the attributes of the stress-strain state of the structure and the system of angles of inclination of the sections are constructed. The configuration of the anchor and retaining wall, which will minimize the potential deformation energy of the system, is found within the framework of the BEA method. Using the numerical output data, the validity of the proposed method is demonstrated. The realization of calculations is reduced to the search for the extremum of the objective function of n variables where the potential deformation energy acts as a functionb and the combination of angles of inclination of the system's breakdown sections as variables. The solution of the problem is implemented by the conjugate gradient method. as a result of calculations, an image of the structure is obtained that minimizes the introduced criterion.
Keywords: retaining walls, deformation energy, curved surfaces, rationalization.

Authors: Kaveh Ali , Khavaninzadeh Neda
Published: December 2022

In this paper, the purpose is to present an efficient graph method for the analysis of truss structures using the force method and compare the computational time with that of the stiffness approach. Naturally, the results of the optimization and the accuracy of calculation for both methods are identical, but the calculation time for the force method is less when the degree of static indeterminacy (DSI) is smaller than the degree of kinematic indeterminacy (DKI) of the structure. Three examples are designed, and optimization has been performed using the ECBO algorithm in MATLAB.

Authors: KULA Sultan Selen
Published: December 2022

The study aims to determine the predictive relationship between self-efficacy beliefs, attitudes toward the teaching profession, and teaching motivation among pre-service teachers. The study, in which 364 pre-service teachers participated, is designed as a correlational survey model. Teachers’ Sense of Self-efficacy Scale, Attitude Scale of the Teaching Profession, and Motivation to Teach Scale are used as data collection tools. The independent variables in this study are willingness to choose the teaching profession and academic achievement. The dependent variables are teacher self-efficacy, attitudes toward the teaching profession, and teaching motivation. The result of the study suggests that as the general academic achievement average of pre-service teachers increase, their perceptions of teaching self-efficacy, teaching attitudes and teaching motivations also increase. The fact that pre-service teachers choose the teaching profession voluntarily affects their teaching self-efficacy perceptions, teaching attitudes and teaching motivations positively. There is a significant relationship between the pre-service teachers' teaching self-efficacy beliefs, teaching attitudes towards teaching, and teaching motivation levels. It can be concluded that intrinsic motivation toward teaching and teaching profession self-efficacy beliefs have a significant effect on attitudes toward teaching.

The main goal of this research is to develop a measurement tool that will determine the beliefs that guide school administrators' practices based on X and Y theory and the relationships between of level of these beliefs and other variables that school administrators use in management practices. The theory was tested with the scale developed in the research. Furthermore, the levels of school administrators' beliefs, which are assumed to guide their practices based on X and Y theory, were revealed in the research using data obtained during the scale development study; it was determined whether the demographic variables of school administrators differed according to the subscale (X and Y subscale) scores. Relational and causal comparison strategies were used in this quantitatively constructed investigation. Research data were collected from three sample groups in the Erzurum sample. It has been determined that there is a significant difference in the X theory subscale score in favour of school administrators working in primary schools. The study concluded that, based on X-Y theory, the assumptions of school administrators that shape management practices could be determined by the School Administrators' Beliefs in the Nature of Human Scale.

Tensiones entre viejas y nuevas tradiciones de enseñanza en la formación de Contadores Públicos y Licenciados en Economía
Authors: Vuarant Salomé
Published: December 2022

Este escrito problematiza las tensiones entre las viejas y nuevas tradiciones de enseñanza en la formación de grado de contadores públicos y licenciados en economía de la Facultad de Ciencias Económicas de la Universidad Nacional de Entre Ríos, cuya sede se encuentra en el litoral de la República Argentina en la ciudad de Paraná. En este se analiza cómo la emergencia de “nuevas cuestiones sociales”, tales como, la problemática del emprendedorismo y de género se permean entre los contenidos curriculares y las prácticas profesionalizantes, replanteando las tradiciones de enseñanza y cuestionando la formación académica. Se recurre a un abordaje metodológico socio antropológico y etnográfico de la vida institucional, y a una perspectiva epistemológica centrada en las Epistemologías del Sur. Se concluye que el desborde de las “nuevas cuestiones sociales” se cuela entre las prácticas de enseñanza, pero en sentidos no tan unívocos, en acciones puntuales y con intervenciones contradictorias que tensionan la relación entre la Contabilidad y Sociedad.

Published: December 2022

Introduction: Gattinoni et al. have recently introduced a new parameter: the “alactic base excess” (ABE). ABE is equivalent to the number of strong acids, other than lactate, which are present in the plasma in abnormal concentrations, negative ABE being associated with higher mortality in sepsis. Hemoperfusion (HPF) is an extracorporeal procedure that involves the passage of blood through an adsorption cartridge, where solutes are removed by direct binding to the sorbent material. Then, it was decided to explore the influence of HPF on negative ABE value in sepsis.
Materials and methods: Basal values of ABE, standard base excess (SBE), and lactate (mean, standard deviation [SD]) were obtained. The difference between these parameter values before and after four sessions of HPF (HA330) (delta value) was evaluated. Student’s t-test and Wilcoxon test were applied.
Results: From 32 patients (age: 57±13) suffering from respiratory insufficiency secondary to COVID-19 who were treated with HPF in the critical care unit of Clinica de la Mujer, Bogotá (Colombia), 6 patients presented with metabolic acidosis with negative ABE value (‒2.7±1) with negative SBE (‒4.7±1) and high lactate serum value (2±0.7 mmol/L). Delta ABE, SBE, and lactate were: 7.7 (p = 0.005), 6.1 (p = 0.003), and 1.6 (p = NS), respectively. Thus, negative ABE was significantly reversed by HPF, since SBE value turned positive without significant change in lactate.
Conclusion: Negative alactic parameter was significantly reversed by HPF in septic patients. It is necessary to carry out evaluations in larger groups to estimate their impact on clinical outcomes.
FEDIR DANYLOVYCH OF OSTROH: RUS’ DUKE, DESCENDANT OF THE ROMANOVYCHI DYNASTY AND HUSSIAN HETMAN IN THE CZECH
Authors: KOZAK Solomiia
Published: December 2022

The article considers the participation of duke Fedir Danylovych of Ostroh in the vortex of the Hussite Wars. It is noted that this issue remains poorly studied and debatable, and there is no clear answer as to whether Fedir Danylovych was mentioned in the sources of the time as «Friedrich von Ostrog». It is taken into account that such an important stage of the duke, as his participation in the events of the Hussite Wars, is often underestimated and denied. However, assumptions were made and arguments were given that it was Fedir Danylovych who had every reason to fight on the side of the Hussites.

The hypothesis was supported that the knight and politician, who was Fedir Danylovych, could indeed take part in the Hussite Wars, later managed to support Svidrigiello, and only after 1437, after his 70th birthday, accept the monk.

Based on the analysis of the previous political activity of duke Fedir Ostrohsky, it is noted that on the eve of the events in the Czech, the duke most likely participated in the Rus’ delegation to the XVI Ecumenical Council of Konstanz in 1414-1418th relied precisely on the dynastic tradition of sovereign statehood, the bearer of which he was as a descendant of Monomahovychi-Romanovychi.

It is taken into account that the Czech economic, cultural, and political contacts with Rus’ began long before the Hussite Wars. Examples of such Rus’-Czech relations are given, and what parallels and bases they had for a new round of communication.

The course of Fedir Danylovych's participation in the campaigns and battles of the Hussite times in the Czech and Slovakia is described. Attention is drawn to the debatable aspect of the prince's possible allied relations with the Hungarian King Sigismund I of Luxembourg, the main opponent of the Hussites. It has been suggested that such relations may have been due to a meeting of the parties to the Bratislava conflict in April 1429 and an international congress of rulers in Lutsk in 1429, at which Sigismund could decide on the coronation of Vytautas and the establishment of the Kingdom of Lithuania. It is stated that such an eventful course could be of interest to the Ostroh duke, who sought to expand and strengthen his ancestral heritage.

The assumption that Fedir Danylovych served only the Polish King Władysław II Jagiełło all his life was rejected. It is concluded that one of the main reasons for duke Fedir Danylovych's participation in the Hussite Wars was that he was looking for ways to restore his own rights to hereditary possessions. It was emphasized that as a man of war, it was natural for duke Ostroh to fight alongside the Hussites almost to the end of his life.
«ПОДЛѢ ТВОИ СТРЕМЕНЬ»: A LITTLE-RESEARCHED CHIVALRY EPISODE FROM THE LIFE OF HALICIAN DUKE YAROSLAV VOLODYMYROVYCH
Authors: PARSHYN Illia , MERENIUK Khrystyna
Published: December 2022

The article examines the symbolic meaning of the horse’s stirrup as a sign of taking a vassal oath. The analysis of the problem was carried out based on the study of the broader context of the rituals of European chivalry. In particular, it is shown the distinction between the rank of Officium stratoris and Officium stratoris et strapae. Based on the use of Hungarian medieval monuments, as well as Kyiv and Volhynia chronicles (Ipatian chronicle collection), it was proved that the representatives of the military elite of the Halychyna and Volhynia lands were familiar with the difference in these rites – from showing respect to the rider (when holding the bridle) to indicating a direct dependent position (when holding the stirrup). These customs appeared in England, but were also extremely popular on the territory of continental Europe, primarily in the Holy Roman Empire. Perhaps this tradition came to Rus’ from the German lands, where already from the XIV century similar chivalric rituals began to be recorded in the city laws. So, such traditions passed into the sphere of medieval legislation.

In the research, the main emphasis is placed on the case of 1153, when after the death of his father, the prince of Halychyna Yaroslav Volodymyrovych (Osmomysl) offered to negotiate peace with the Kyiv duke Izyaslav Mstislavovych. Through intermediaries, the prince offered the formula «подлѣ твои стремень», which, according to medieval etiquette, meant recognition of his subordinate position. Note that half a century later, the boyars of Halychyna did not forget the significance of this ritual and tried to unite other service people around them. This is demonstrated by the example of the boyar Dobroslav, who in 1241 gathered around his stirrup, according to the chronicler, many other warriors. Dukes Danylo and Vasylko then correctly understood the demonstration of the proud boyar and deprived him of the lands he had seized. It is possible that some of the new servants of the boyar Dobroslav were expelled from the Halychyna land by Romanovids earlier. Thus, the Rus’ military elite understood the rituals of medieval chivalry. It proved the existence of strong connections between the nobility of these princely lands and the European culture of that time.

The article addresses the problem of religious and political activity of the Greek Catholic clergy of Northeastern Hungary between 1860 and 1867. Considerable attention is paid to analyze the role of the local Rusyn leaders. Among the nationalities of the Hungarian Kingdom in the ХІХ century, the Rusyns were considered to be the poorest people, both materially and culturally. Their society was truncated, in other words, incompletely structured, consisting of the vast majority of peasants. The author highlights that in the absence of nobility and citizenry, their Greek Catholic clergy served as elites. Their ecclesiastical organization provided an appropriate framework and base for the development of their national culture and literature. The most significant ecclesiastical structure of the Rusyns in Northeastern Hungary was the Greek Catholic Eparchy of Mukachevo, which had jurisdiction over seven Hungarian counties (Zemplén, Ung, Bereg, Ugocsa, Máramaros, Szabolcs and Szatmár). The current bishop of the diocese resided in Uzhhorod was the number one leader of the Rusyns.

It is alleged that the so-called October Diploma, enacted by Austrian Emperor Franz Joseph on October 20, 1860, proclaimed a return to constitutional principles. On the basis of analysis of the various programmes of the Greek Catholic priests of the Eparchy of Mukachevo, it is established that the October Diploma had a great impact on the Rusyns of Hungary. This time, Adolf Dobriansky, a councillor of Hungary’s Lieutenancy Council claims the federal transformation of Hungary, the establishment of an independent Rusyn congress and a Greek Catholic archbishopric. As noted, his ideas also influenced many Rusyn priests. The traditionally pro-Hungarian Bishop of Mukachevo, Vasyl Popovych and his followers rejected Dobriansky’s ideas because of their «radical» nature. Instead, the Consistory of Uzhhorod wanted to accept nationality demands exclusively in cooperation with the Hungarian Parliament.

The author comes to the conclusion that after the Austro-Hungarian Compromise of 1867, the pro-Hungarian Greek Catholic clergy of the Eparchy of Mukachevo was satisfied with the rights enshrined in the Nationalities Law of 1868. In the end it is revealed that the clergy believed: the state subsidies of the Diocese of Mukachevo would have been at risk by claiming nationality rights. The article summarizes the new material on the topic under study, introduces it into scientific circulation.

The response of algae to stressors that affect their survival and growth appears to be strictly related to their dimension and shape. Coralline algae (Corallinophycidae, Rhodophyta) show a variety of morphological types that may play a role in their tolerance to stressful conditions. Nevertheless, only a few studies have investigated their response to multiple stressors when grouped by morphology. The aim of this work was to investigate the performance of the 2 main morpho-functional groups of coralline algae (nongeniculate and geniculate) in response to different stressors acting simultaneously (presence of fleshy macroalgae and/or benthic mucilage and sediment deposition). For this purpose, a manipulative field experiment was conducted on superficial rocky substrata (subtidal, 0.5 m depth) in the Tavolara Punta Coda Cavallo Marine Protected Area, Sardinia, in 2016-2018. The effect of each stressor, alone and in combination, was tested on the 2 groups of algae (4 treatments applied in triplicate), with the percent substratum covered by living coralline algae and the net primary production as response variables. Results showed that although some common trends were evident, different effects were observed for each morpho-functional group in relation to the considered response variable. These results highlight the importance of considering morpho-functional classification when predicting the response of coralline algae to disturbance and identifying their main threats.

Amiodarone seems to exhibit some antiviral activity in the disease caused by SARS-CoV-2. Here we have examined the SARS-CoV-2 disease course in the entire population of the Czech Republic and compared it with the course of the disease in patients treated with amiodarone in two major Prague’s hospitals. In the whole population of the Czech Republic SARS-CoV-2 infected 1665070 persons (15.6 %) out of 10694000 (100 %) between 1 April 2020 and 30 June 2021. In the same time period only 35 patients (3.4 %) treated with amiodarone were infected with SARS-CoV-2 virus out of 1032 patients (100 %) who received amiodarone. It appears that amiodarone can prevent SARS-CoV-2 virus infection by multiple mechanisms. In in-vitro experiments it exhibits SARS-CoV-2 virus replication inhibitions. Due to its anti-inflammatory and antioxidant properties, it may have beneficial effect on the complications caused by SARS-CoV-2 as well. Additionally, inorganic iodine released from amiodarone can be converted to hypoiodite (IO-), which has antiviral and antibacterial activity, and thus can affect the life cycle of the virus.

Teori tujuan pemidanaan mengalami perkembangan secara terus-menerus. Teori tujuan pemidanaan yang umumnya diketahui hanya teori absolut, teori relatif, dan teori gabungan. Akan tetapi, teori tersebut merupakan teori tua yang meskipun sampai saat ini masih eksis dan tetap digunakan dalam penerapan dan pelaksanaan hukuman pidana di Indonesia. Penelitian ini bertujuan untuk mengetahui perkembangan teori tujuan pemidanaan yang selama ini hanya dikenal tiga teori pemidanaan (teori absolut, teori relatif, dan teori gabungan) dapat digunakan dalam sistem peradilan pidana di Indonesia masa mendatang. Metode penelitian yang digunakan dalam penulisan ini, yaitu metode penelitian normatif dan menggunakan bahan hukum primer dan bahan hukum sekunder. Adapun hasil yang didapatkan dalam penelitian ini adalah selain ketiga teori tersebut masih terdapat beberapa teori tujuan pemidanaan yang mungkin nantinya dapat digunakan dan diterapkan dalam sistem peradilan pidana di Indonesia, antara lain teori keseimbangan dan teori kontemporer, dan teori pengayoman.
Laparoscopic surgery for clear cell endometrial carcinoma, is it a realistic approach?

Clear cell endometrial carcinoma is an aggressive form of endometrial cancer that has a poor prognosis for survival. Over the past ten years, laparoscopic surgery has replaced open surgery as the preferred method of treating early-stage endometrial cancer. However, its effect on the prognosis of patients with clear cell carcinoma is still unclear. In the current systematic review, we examined the information that was published in the following databases: Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials, CENTRAL, and Google Scholar. Three studies were found to be significantly diverse; as a result, meta-analysis was not possible. Current research reveals that compared to traditional laparotomy, minimally invasive surgery does not significantly influence progression-free and overall survival rates; nevertheless, given the relative dearth of data, more research is required before the technique’s safety can be determined.
Ovarian Vein Thrombosis

Published: December 2022

Ovarian vein thrombosis (OVT) is a rare type of venous thromboembolism most common diagnosed in the postpartum period and peaking around 2-6 days after delivery. Clinical symptoms are not specific including fever and abdominal pain and the right ovarian vein is more frequently involved (70-80% of cases). The diagnosis of OVT is a clinical challenge because there are multiple other conditions that can present similarly, including ovarian torsion, tubo-ovarian abscess, pelvic inflammatory disease, puerperal endometritis, appendicitis, inflammatory bowel disease and pyelonephritis. Ultrasound Doppler is the first-line imaging; however, most cases are confirmed with computed tomography or magnetic resonance imaging. Mortality related to ovarian vein thrombosis is low due to the combination treatment of broad-spectrum antibiotics and anticoagulation. Extension of thrombus to inferior vena cava or renal veins and rarely pulmonary embolism could also occur. OVT is actually a type of deep vein thrombosis that could be life-threatening however mortality is low due to the combination treatment of broad-spectrum antibiotics and anticoagulation. Anticoagulant treatment duration of 3 to 6 months has been recommended like typical cases of venous thromboembolism.
