Radiation Induced Liver Injury - A Case Report
Authors: L Rokade M
Published: August 2023

The non-classical focal liver injury is confused with tumor progression or metastasis. Radiological appearance can prevent confusion and needless invasive biopsies. We encountered a 24-year old female patient with invasive ductal carcinoma of the right breast grade 2 ERPR and Her2neu positive with axillary and pectoral lymph nodal involvement treated with adjuvant chemotherapy. In surveillance ultrasound of the abdomen the sonologist reported an altered area of echogenicity in the liver. Due to concern for metastasis this was followed by a PET CT. A subcapsular hypoattenuating lesion was reported and referred to the radiology team for further work up and biopsy consideration. The classical straight edge sign demarcation was noted on the MRI as well as on the PET CT. A diagnosis of focal liver injury post radiation was made and the patient is being followed up closely and continues to be asymptomatic.

Behavioural Intention to Purchase Remanufactured Automotive Components: The Mediating Effect of Attitude
Authors: Asyraf Ahmad , Zakaria Zukarnain , Jamil Rosillah
Published: August 2023

Purpose: The aim of this study is to examine the mediating factor of attitude on the consumers’ intention to purchase the remanufactured automotive components in Malaysia.
 
Theoretical framework: The Theory of Perceived Behaviour (TPB) can be expanded, in accordance with Ajzen (1991), by adding new variables or modifying the present paths between variables. As previously mentioned, the TPB contends that attitude, subjective norms, and perceived behavioural control serve as the three pillars that support behavioural intention. However, other researchers asserted that the model's ability to predict actual behaviour may be improved by other variables that are not been included by TPB (Armitage and Conner, 1999, 2001). Therefore, the present study attempts to extend the TPB by including new variables, i.e., perception on the quality, perception about price and environmental consciousness.
 
Design/Methodology/Approach: The quantitative study used primary data that gathered from 561 vehicle users using purposive sampling. Data were analysed using Partial-Least Square - Structural Equation Modelling (PLS-SEM) to examine the mediating effects and the strength of the relationships among the constructs.
 
Findings: The results reveal that price (P) and subjective norm (SN) have significant positive relationship with attitude. Furthermore, attitude, subjective norm, price, and perceived behavioural control (PBC) exert significant positive effect on the behaviour intention (BI) to purchase remanufactured automotive components. Moreover, the findings indicate that attitude significantly mediates the relationship between price, subjective norms and behaviour intention.
 
Research, practical & social implications:  The results of this study emphasized that remanufacturers need to implement various marketing strategies including discounts and advertisements to bring positive influence on consumers’ behaviour intention to purchase remanufactured automotive components.
 
Originality/Value:  This study extends the Theory of Planned Behaviour (TPB) by incorporating price, quality and environmental consciousness perceptions. The expanded theoretical framework improved the predictive ability of the TPB.

Analisis Pengaruh Ketidakseimbangan Beban Pada Transformator Distribusi Terhadap Rugi Daya (Losses) Dengan Digsilent Power Factory di PT.PLN (Persero) ULP Ngunut
Authors: Prayoga Arifran Bima , Suprianto Bambang
Published: August 2023

Suatu pembebanan yang tidak seimbang merupakan hal yang pasti terjadi dalam sistem distribusi tenaga listrik. Suatu pembebanan pada transformator distribusi yang tidak seimbang tentunya mengakibatkan munculnya arus pada netral transformator. Timbulnya arus netral mengakibatkan bertambahnya nilai rugi daya (losses) pada jaringan tersebut. Sehingga daya yang disalurkan oleh PT. PLN (Persero) tidak sebanding dengan daya yang terjual. Nilai rugi daya yang tinggi pastinya akan sangat merugikan pihak penyedia listrik yaitu PT.PLN (Persero). Simulasi dengan software Digsilent Power Factory dilakukan untuk mengetahui trafo yang mengalami ketidakseimbangan beban dan bagaimana pengaruhnya terhadap rugi daya. Penelitian ini dilakukan di PT. PLN (Persero) ULP Ngunut pada Penyulang Ngunut. Hasil simulasi ketidakseimbangan beban menunjukkan persentase ketidakseimbangan terbesar terdapat pada trafo ED127 yaitu 42,42% dengan persentase rugi daya mencapai 29,20%. Setelah dilakukan penyeimbangan beban, persentase ketidakseimbangan beban pada trafo ED127 turun menjadi 4,81% dengan persentase rugi daya pada 0,33%.

The presented article demonstrates the application of the method of mathematical design of the experiment (MPE) in the development of the composition of the lyophilized capsule mass of a biopharmaceutical composition with antimicrobial and probiotic effects. The factors of the technological process that affect the quality indicators of the capsule mass of the biopharmaceutical composition were studied: carriers for immobilization, gastro-resistant formers, antifriction substances. The work studied the bacteriotropic properties of the lyophilized capsule mass of the biopharmaceutical composition, which include antimicrobial activity, gastric resistance, probiotic activity, as well as technological properties such as disintegration and residual moisture. Particularly important for the lyophilized capsule mass of the biopharmaceutical composition are the indicators of antimicrobial and probiotic activity, since they determine the therapeutic orientation of the composition, and the study of such indicators of the capsule mass as gastric resistance and disintegration are among the most critical properties, since the composition contains a bacteriophage, labile to the action of acids and, accordingly, to ensure the preservation of the bacteriotropic properties of the biopharmaceutical composition, the central task was to create a protective shell, in this regard, the method of introducing excipients is a key factor. Residual moisture for lyophilized capsule mass has a major impact on the stability of the pharmaceutical substance during storage, in connection with this, this indicator was studied in this experiment. Achieving all acceptable values for creating a gastro-resistant composition is based on the correct selection of the formulation. Based on the data obtained, partial and generalized Harrington desirability functions were calculated. In conclusion, a conclusion was made about the most acceptable model composition and the optimal technology for manufacturing the capsule mass of the biopharmaceutical composition.

The purpose of the study is to determine the direction of development of the voluntary medical insurance market and pharmaceutical insurance for the population of Russia. The materials of the study were the data of the statistical reporting form of insurers (reporting of the Bank of Russia); statistical indicators and information about individual subjects of the insurance business; the register of licenses issued to insurance companies, Insurance Rules, data on the population of the Federal State Statistics Service. The method of content analysis, the method of analysis of time series, methods of analysis, synthesis and generalization of information were used. It is revealed that the voluntary medical insurance market in 2022 is characterized by the following trends: a decrease in the volume of insurance premiums, a stable number of insurance contracts, the growth of the corporate segment, a decrease in the amount of payments, a decrease in the number of insurers working in the field of health insurance, high monopolization of the market. A significant increase in the share of corporate voluntary medical insurance shows not only the unwillingness and/or inability of individuals to purchase insurance policy, but also the alertness of insurance companies to this insurance sector in times of turbulence. The top 10 (by the amount of insurance premiums) companies operating in the field of voluntary medical insurance have been identified. Drug insurance in the form of a separate program is offered by 6 companies from the top 10 offer a separate drug insurance program; all 6 companies apply a franchise, the level of which ranges from 10% to 100%; 2 companies include the provision of biologically active additives and medical products, 1 company offers the provision of specialized nutrition products. The basic tariff rates for drug insurance programs are significantly higher than those for medical care insurance.

The article collects and analyzes the available information on the pathogenesis, features of diagnosis and course of acute pancreatitis in patients with HIV and COVID-19 based on cited scientific papers. Patients with HIV/AIDS can be affected to a wide range of factors for the development of acute pancreatitis, such as opportunistic infections, neoplasms and metabolic changes due to the use of antiretroviral drugs. Morphological changes in the pancreas, including its endocrine, exocrine apparatus and interstitial tissue, as well as the ductal system, observed in about 20% of HIV-infected patients. Pathological and morphological changes in the pancreas during autopsy detected in 90% of cases. With the introduction of combined antiretroviral drugs, new metabolic disorders appeared, such as liver steatosis and lactic acidosis, which also have a toxic effect on the pancreas. COVID-19 can cause severe complications from the heart, lungs, brain, kidneys, blood vessels and other vital human systems and organs. Scientists associate the effect of the virus on pancreatic cells with the placement of ACE-2 receptors in the organ. The presence of ACE-2 in non-respiratory organs has a positive effect on the functioning of these tissues. As is known, COVID-19 infection was caused by the SARS-CoV-2 virus. This virus actively replicates using intracellular ARF-2 and then destroys the host cell when it enters the extracellular space [1]. Although COVID-19 refers to respiratory infections, doctors recognize that the disease is multisystem, in other words, it can affect any organ [2]. During the period of COVID-19 disease, the human excretory system ceases to cope with its functions due to oxygen starvation, blood detoxification does not occur. Against this background, multiple organ failure and numerous edemas of the tissues of internal organs develop. The organs of the endo- and exocrine systems suffer, including the organ of mixed secretion – the pancreas. The study of the impact of the new coronavirus infection is the most relevant nowadays, from that moment this infection is relatively young and poorly studied. By analyzing rare clinical cases, we can predict the consequences of the disease and anticipate late complications. The analysis was made on the basis of laboratory and morphological features.

Oral infectious and inflammatory diseases occupy a special place in the practice of dentists and are considered to be one the most common reasons why patients request for dental care. In this regard, it is important to identify the mechanism of inflammation development and possible treatment regimens. To date, there are a sufficient number of synthetic drugs for the treatment of inflammatory processes in human body, their effectiveness has been proven and undeniable, but the side effects associated with their use are also extensive. At present, the most urgent question is to be the search for other, natural remedies for the treatment of various diseases, including inflammatory ones.
This literature review reflects information about modern views on the etiopathogenesis of oral infections and inflammatory diseases. Analysis of methodological approaches to the treatment of inflammatory processes in the oral cavity was carried out. The possibilities of traditional and non-traditional methods of treating patients with an emphasis on using non-drug herbal remedies are considered. Compositions of popular drugs that are currently used in dentistry for the treatment of oral mucosal diseases were studied. Main groups of substances that are a part of medicinal plants have been studied, as well as their anti-inflammatory activity.
So, despite the availability of anti-inflammatory drugs, one should not exclude the possibilities of alternative ways, such as herbal medicine/phytotherapy, aromatherapy, hydrolatotherapy, etc. These methods are also noted to be effective, biologically safe. A greate variety of approaches and treatments for inflammation allow better and more personalized therapy.

Published: August 2023

This article is dedicated to the process of teaching translation and interpreting to students of language specialties using information and computer technologies. The authors substantiate the importance of mastering translation skills for a successful professional career as a translator in the future. The authors also formulate a number of didactic principles for teaching students the skills of translation. It is already difficult to imagine the modern methods of teaching foreign languages in general and translation in particular without the use of modern ICT tools, since their use greatly facilitates and enriches the teaching process and translation work. The effectiveness of using ICT in teaching translation largely depends on how they are used, on how competently the teacher knows the methodology of working with ICT, on the ability of the teacher to solve the difficulties that arise when working with ICT, as well as on the ways of interacting with students. The purpose of this study is to analyze modern ICT used for text translation, as well as to develop methodological recommendations and exercises for teaching translation and interpreting to students of language specialties. The theoretical significance of the study lies in identifying the features of teaching translation and interpreting, taking into accounts the differences between Russian and English. The practical significance, on the one hand, is represented by methodological recommendations proposed by the authors of the study and a set of exercises for developing translation skills in the classroom in a foreign language. On the other hand, it is represented by other linguistic disciplines that are not directly related to translation, but are related to the teaching and learning of foreign languages and foreign language communication.

Background/Aim: In recent years, there has been an increase in the prevalence of obesity and its complications, along with a growing awareness of healthy nutrition. As a result, consumers are seeking to incorporate more functional foods into their diets. Chia and flax seeds have gained popularity due to their soluble fiber and antioxidant capacity. This study aims to compare the effects of consuming cakes made with the addition of chia and flax seeds on blood glucose and insulin levels, as well as evaluate their impact on post-consumption satiety response in individuals.
Methods: This randomized, double-blind, self-controlled experimental study involved 12 volunteers (19–64 years old) who were free from acute or chronic diseases. The participants had a body mass index (BMI) value between 18.5 and 24.9 kg/m2 and a Beck Depression Inventory score of 8 or below. The study investigated the effects of standard and test cakes containing 50 g of digestible carbohydrates, including chia-added cake, flaxseed-added cake, and chia+flaxseed-added cake. Postprandial blood sugar, insulin, and subjective satiety responses were assessed. A standard nutrition program (diet: 60% carbohydrates, 20% protein, 30% fat) was implemented at least one week before the study, and participants were asked to maintain 24-h food consumption records the day before the test days. Throughout the study period, individuals were instructed to avoid caffeine, medication, nutritional supplements, and heavy physical activity. Cake consumption sessions were conducted at the research center, with participants visiting four times in total, with at least 1-week intervals. Fasting for 10–12 h prior to each visit, saturation responses were measured using a visual analog scale at 0, 15, 30, 60, 90, 120, and 180 min. Blood samples were also collected to assess blood glucose and insulin levels.
Results: The study revealed that cakes containing chia and flaxseeds, compared to the standard cake, as well as flaxseed-added cake compared to chia-added cake, resulted in higher plasma glucose under-curve values and saturation responses and lower hunger responses (P=0.038, P=0.016, P=0.004, respectively).
Conclusion: The findings indicate that both chia and flax seeds impact glycemic control and the sensation of satiety, with flaxseed exhibiting greater effectiveness than chia.

Sinheung Military Academy as Seen from the Data Collection of the Japanese Diplomatic Archives: Bright and Darkness of Secret Intelligence Reports
Authors:   The Association for Korean Modern & Contemporary History, KIM Joo-yong
Published: August 2023

The materials related to Shinheung Military Academy, owned by the Diplomatic Archives of the Ministry of Foreign Affairs of Japan, along with materials left by independence activists, such as Seokju’s posthumous death, Baekha Diary, and Won Byeongsang’s memoirs, must be very important for the study of Shinheung Military School. Among the materials used in the study of Shinheung Military Academy, the most mentioned are the materials left by independence activists. However, in order to more clearly reveal the reality of Shinheung Military Academy, it is urgent to utilize the materials owned by the Diplomatic Archives of the Ministry of Foreign Affairs of Japan. Although it contains a lot of incomplete information such as spying, it is of high usefulness as it provides relatively extensive information on the current status of Korean migration in the West Gando region and of organizations directly or indirectly related to Shinheung Military Academy, such as Gyeonghaksa, Bumindan, and Jasakgye. The materials possessed by the Japanese Diplomatic Archives are reports of consuls and vice-consuls of consulates dispatched to the country, and secret agents, and are essential data for research on the history of the Korean independence movement. In particular, the reports of the spies were evidence that revealed the ‘inner life of the independence movement’ of those who had deeply infiltrated the Korean independence movement world.
Sinheung Military Academy was the organization that the Japanese paid the most attention to in the West Gando region. It was because it was an organization that encompassed both the aspect of cultivating the independence army and the aspect of being the center of Korean society. Therefore, among the materials of the Ministry of Foreign Affairs of Japan, Shinheung Education Association, Livelihood Association, and Shingye, etc, which have not been revealed so far, are considered to be data that will reveal more abundantly the reality of the independence movement of Shinheung Military School and outlying organizations and the situation related to bomb production and importation into Korea in the future. In addition, there is an aspect in which research on the Bumindan and the Han Chinese Association has not been relatively progressed compared to the known status so far.
