Authors: Subba Jas Raj , Wangchuk Sangay
Published: June 2022

The study was conducted during 2020-2021 at the Department of Physical Science, Sherubtse College, Royal University of Bhutan with an objective to find out whether the food items that we consume daily are adulterated or not. Various food items, both locally produced and imported, were purchased from different Dzongkhags and analyzed in the laboratory for the presence of adulterants. Locally produced food items purchased were local butter, local cheese, local honey, local chili powder, beaten rice, etc. and imported food items included pulses, chili powder, turmeric powder, spices, milk, etc. Qualitative analysis of food items for detection of adulterants was done by a simple chemical test as per the standard procedure followed by various researchers. The finding showed that local butter was found to be adulterated with banana and dalda, local honey was adulterated with sugar syrup, and beaten rice was adulterated with chlorophyll pigment. Imported lentils were adulterated with Metanil yellow. Chili powder and some spices were adulterated with artificial colours and dust particles.
Using liquefied petroleum gas to reduce the operating cost of the Ankerlig peaking power plant in South Africa
Authors: Clark S. , McGregor C. , Van Niekerk J.L.
Published: June 2022

Along with the load-shedding problem that Eskom is having with the current generation system, the operator is forced to use its peaking plants at Ankerlig and Gourikwa in the Western Cape much more than planned. The two plants are set up for dual fuel operations, able to be fuelled with diesel as well as gas. As Eskom does not have access to natural gas, both plants have been fuelled with diesel. For the last three years, 2019 through 2021, Eskom has expended an average of over R4 billion per year on diesel fuel for its peaking plants, with the majority of this at Ankerlig and Gourikwa. For 2022, in their request for a rate increase, Eskom noted that their anticipated diesel fuel expenditures will increase to over R6.5 billion. This could be reduced by more than half if the plants were fuelled with natural gas. The problem Eskom faces is sourcing natural gas to fuel these plants. There has been consideration of liquefied natural gas importation into the Western Cape that could be utilised to fuel the Ankerlig plant. However, the high capital cost for this option has led to delay in the commencement of this project. There is another alternative that can be implemented in a short time-frame, using currently available gas, in the form of liquefied petroleum gas. With this fuel, the Ankerlig peaking plant could be switched to gas fuel and Eskom would have a significant reduction in the cost of fuel. In this study the economic benefit of this fuel change option is analysed.

Determinants of Somali Student's Entrepreneurial Intentions: The Case Study of University Students in Mogadishu
Authors: ALİN Liban Daud , DİL Esra
Published: June 2022

This study investigates the factors that influence Somali young people's entrepreneurial intentions, particularly local university graduates. This article aspires to make a substantial contribution to Somalia's entrepreneurship. To support the research, the researcher employed the Theory of Planned Behavior and the concept of entrepreneurial intention. This research was conducted at eleven universities in Mogadishu, Somalia's capital. University students who are now exposed to changes in the entrepreneurial environment served as the study's unit of analysis. Because of the ease of access to the sample units, this study took a quantitative approach and used a non-probability convenience sampling method. A total of 380 sample replies were obtained from various universities after the questionnaire was distributed. The hypothesis was put to the test, and the results show that personal attitude and perceived control behavior play a significant role in entrepreneurial intent. Besides, the subjective norm does not affect entrepreneurial intention.
Not a crisis nor civil war, but a foreign aggression: Why did Russia attack Ukraine in 2014?
Authors: MORKVA Valeriy
Published: June 2022

On 18 March 2014 Vladimir Putin, the President of the Russian Federation triumphantly declared the “reunification of the Crimea” with Russia. However, this was not the end, but just the beginning of overambitious plans to annex the whole South-Eastern Ukraine with its large industrial centers and mainly Russian-speaking population. The small groups of the Russian secret forces and paid “political tourists” tried to orchestrate a series of separatist pro-Russian meetings in a number of cities in the South-Eastern Ukraine. Ukrainian society faced with systematically planned foreign aggression, camouflaged as a “civil war” of Russian-financed, Russian-armed and directly Russian-led “miners and tractor-drivers” against a “fascist anti-democratic junta” in Kyiv. What in Kremlin’s language came as a “reunification” and “civil war”, for the rest of the world became a blatant violation of international law and meets the definition of international aggression adopted by the United Nations General Assembly in 1974. Thus, the most fundamental question remains not who initiated yet another protracted armed conflict in the post-Soviet space, but reasons lying behind it. The article attempts to look into what might be the driving force of the Russian aggression in Ukraine.

WATER IN THE BULGARIAN WORLD PICTURE (a case study of the folk songs of the Bulgarians in Ukraine)
Authors:   O. O. Potebnia Institute of Linguistics of the NAS of Ukraine, MALASH Oleksandra
Published: June 2022

The paper provides a study of the symbolism of water in the Bulgarian linguistic culture. The author analyzes texts of the folk songs recorded by several Ukrainian and Bulgarian scholars from the descendants of the Bulgarian migrants in the last half of the 18th – 19th c., which are currently living in the regions of Odessa, Zaporizhzhia, Mykolaiv, and in the Autonomous Republic of the Crimea. The role of the vocabulary around the hydrosphere in the Bulgarian linguistic world image is researched. It is outlined that water is a universal symbol of the human life. Water is thought as a primary substance that has created the Earth and the live nature. It is used in different liminal rituals as something able to purify, to heal, to charge with the live power and to bless people. And this belief in the sacral properties of water are displayed in the Bulgarian folk songs. The author investigates the linguocultureme “water” and its implementations in “reservoir”, “well”, “spring”, “rain”, “Danube”, “sea” in the folk songs of the Bulgarians in Ukraine. It is established that “water” is a symbol of a border that must be overstepped. “Well” symbolizes the living space of a human, container of the unique sacral water that sacralizes the marriage and love. However, sometimes the well designates the adultery and lewdness. “Spring” is equal to the immortality given to a hero as a thank for the completed mission of the life. “Danube” is a mythic path between the known and unknown world, like “sea” it is a symbol of the separation with the home, and it is particularly true for the Bulgarian migrants whose ancestors had left the motherland. “Rain” represents the reciprocity between the human and the supreme forces. The analyzes of these implementation of the linguocultureme “water” shows the special role of the water in the Bulgarian linguistic world image.

Published: June 2022

AIM: This study aimed to investigate the effect of oxidative stress on the antioxidant defense system and state of lipid peroxidation of the body. MATERIAL AND METHODS: Modeling of oxidative stress was carried out on 240 rats by daily administration of thiram at a dose of 1/50 LD50 (8 mg/kg body weight) in the diet of rats for 4 weeks. The catalytic activity of superoxide dismutase and catalase and the concentration of malondialdehyde and diene conjugates were analyzed. RESULTS: The modeling of subchronic intoxication significantly decreased the activity of catalase and superoxide dismutase (p 0.05) and increased the concentration of malondialdehyde, diene conjugates in blood plasma, erythrocyte mass, and liver homogenate. After experimental subchronic intoxication, antioxidants such as vitamin E at a dose of 8.58 mg/kg and milk thistle extract at a dose of 13.74 mg/kg were used. Using such antioxidants within 30 days had significantly restored the activity of superoxide dismutase and catalase, and it also reduced the concentration of malondialdehyde and diene conjugates in all investigated body media. CONCLUSION: Fungicide intoxication with thiram affects redox homeostasis. In addition, the usage of vitamin E and milk thistle extract can restore the prooxidantantioxidant balance of the body.

Authors: Pavlenko Ilya V. , Gostev Vitaliy N. , Andriukhin Kirill V.
Published: June 2022

Questions concerning the study of mechanotransduction in the skin are currently of interest to many researchers, especially those engaged in the study of the problem of high-quality surgical treatment of soft tissue wounds. The possibility of developing new ways of treating various pathologies of the integumentary tissues, including wound defects, depends on understanding the processes of transmission and transformation of mechanical stimuli coming to skin cells into chains of biochemical reactions. The review presents the main historical stages of the development of scientific knowledge about mechanotransduction, describes the features of mechanotransduction in integumentary tissues, currently known mediators and signaling pathways that realize the transmission of mechanical influences from the cell surface to its nucleus, and also suggests possible directions for using this phenomenon in practice. The work also noted changes occurring at the cellular level during the recoding of mechanical signals in wounds prone to slowing down natural healing processes chronic wounds. We believe that one of the promising trends in the practical application of mechanotransduction is the possibility of using its effects when stretching the skin during the treatment of wound defects of soft tissues.

Published: June 2022

BACKGROUND: Bacteria in the gastrointestinal tract regulate eating behavior and metabolic processes. A number of probiotic strains have a positive effect on glucose and insulin metabolism. A series of studies have demonstrated the effectiveness of autoprobiotic therapy in the treatment of patients with gastrointestinal diseases. The efficacy and safety of an indigenous strain of Enterococcus faecium in overweight patients with type 2 diabetes has not been studied in the past.
AIM: To evaluate the effectiveness of products containing the probiotic strain Enterococcus faecium L3 or the indigenous strain Enterococcus faecium in patients with diabetes mellitus (DM) type 2.
MATERIALS AND METHODS: Patients with diabetes mellitus type 2 were randomized into two groups: group of probiotic therapy with an industrial strain of Enterococcus faecium L3 (11 patients); group of autoprobiotic therapy based on an indigenous strain of Enterococcus faecium (9 patients). Therapy was for 14 days. Before and 10-14 days after the end of therapy, anthropometric parameters were assessed; psychometric testing was carried out; biochemical parameters of blood serum were studied. The intestinal microbiota was studied by real-time polymerase chain reaction.
RESULTS: Probiotic therapy based on Enterococcus faecium L3 and autoprobiotic therapy based on indigenous Enterococcus faecium had no significant effect on glucose metabolism in patients with type 2 DM. In the Enterococcus faecium L3 group and the group of indigenous Enterococcus faecium there was a significant decrease in gastroenterological complaints on scales of the GSRS questionnaire. Patients in both groups showed a statistically significant decrease in the total bacterial mass, an increase in the quantitative content of Lactobacillus spp., a decrease in the population of Bifidobacterium spp. and Bacteroides thetaiotaomicron.
CONCLUSIONS: The probiotic strain Enterococcus faecium L3 and the indigenous Enterococcus faecium do not have a significant effect on the metabolism of glucose and insulin, while they contribute to a similar change in the component composition of the microbiota and a decrease in the severity of gastroenterological complaints.

Authors: Bratilova Ekaterina S. , Kachnov Vasilii A. , Tyrenko Vadim V. , Kolyubaeva Svetlana N.
Published: June 2022

Numerous data indicate a high incidence of cardiovascular diseases against the background of a novel coronavirus infection, including initially healthy individuals. The development of complications such as cardiac rhythm disturbances, myocardial injury, acute coronary syndrome aggravates the severity of the disease and the prognosis. Moreover, signs of structural and functional damage of the cardiovascular system are detected after recovery, which makes prevention issues especially relevant. Various non-modifiable risk factors for the severe course of COVID-19, such as gender, age, heredity, race, environment, can determine the development of complications, including heart disease. In this matter, genetic characteristics are also important. The literature review presents possible genetic predictors and the mechanism of their influence on the development of cardiovascular complications and the severe course of novel coronavirus infection. The identification of specific genetic predictors can determine biological mechanisms that are relevant to diagnostic and treatment strategies. Moreover, recognizing people at high or low risk of severe COVID-19 can contribute to understanding the course of infection in different people and the development of cardiovascular complications. In addition, the determination of genetic markers contributes to the early detection of developing cardiovascular complications against the background of the novel coronavirus infection and elaboration of the personalized prevention strategy.

Authors: Sukhomlinova Irina M. , Bakulin Igor G. , Kabanov Maxim Yu.
Published: June 2022

BACKGROUND: According to the international guidelines and expert opinions, medicines for the treatment of COVID-19 are prescribed off-label; however, the final decision is made by a physician based on an assessment of the risk/benefit ratio for each patient. Global studies of the efficacy and safety of the use of baricitinib, tocilizumab, olokizumab, dexamethasone in the treatment of COVID-19 are ongoing. There is no information about comparative efficacy of these drugs and on the prognosis of their use in COVID-19.
AIM: To compare the effects of pre-emptive anti-inflammatory therapy (PAT) with tocilizumab, olokizumab, baricitinib, dexamethasone in patients with COVID-19 to identify response predictors and the choice of the most effective treatment.
MATERIALS AND METHODS: A retrospective analysis of 229 cases of severe and moderate course of COVID-19 requiring various types of UPT at the Hospital for War Veterans has been carried out.
RESULTS: In the study of 229 clinical cases of severe COVID-19, it was found that the most significant predictors of the effects of anticytokine therapy include C-reactive protein (CRP), body mass index (BMI), body temperature, saturation level and the need for a certain type of oxygen support at the start of a therapy, platelet count, hematocrit, neutrophil count, and duration of the disease from its onset to development of signs of a cytokine storm. The probability of recovery in the patients with early appointment of UPT increases by 13%; the need for additional oxygen support increases the risk of mortality by 5.3 times as it increases with the transition to each subsequent level; an increase in the level of CRP by 1% increases the unfavorable prognosis; an increase in D-dimer worsens the prognosis by 16%.
CONCLUSION: Based on the statistical data obtained by the method of stepwise regression analysis, was proposed method for predicting the effectiveness of proactive anti-inflammatory therapy in novel coronavirus infections.
Influence of risk factors for the development of cardiovascular diseases on the parameters of arterial stiffness in patients with arterial hypertension and atherosclerosis of different degrees of severity
Authors: Sayganov Sergey A. , Gumerova Victoria E. , Gomonova Veronika V.
Published: June 2022

BACKGROUND: Arterial hypertension is widespread in the population, leads to the development of arteriosclerosis and increase of arterial stiffness, and is the main non-lipid risk factor of atherosclerosis development. Multiple studies have shown that increase of arterial stiffness is an independent risk factor for the development of cardiovascular events. However, the influence of traditional cardiovascular risk factors on arterial stiffness in arterial hypertension and atherosclerotic process of different degrees of severity has not been sufficiently studied.
AIM: To assess the influence of traditional risk factors on the parameters of arterial stiffness in patients with arterial hypertension (AH) and atherosclerotic process of varying degrees of severity.
MATERIALS AND METHODS: 133 subjects with AH have been divided into 3 groups depending on the severity of the atherosclerotic process. The control group included 33 individuals without known cardiovascular diseases. All the participants have undergone a standard clinical and laboratory examination, 24hr blood pressure monitoring with assessment of arterial stiffness (AS) parameters. The influence of risk factors on AS parameters has been analyzed for all the participants and separately by groups.
RESULTS: In the AH patients, an increase in the arterial stiffness index (ASI) is associated with an older age and an increase in systolic blood pressure (SBP); an increase in the augmentation index (AIx75) is associated with age; SBP in higher in women. Pulse wave velocity in the aorta (PWVao) is most associated with age, smoking, and family history in patients with hypertension and subclinical atherosclerosis. An increase in AIx75 is associated with an older age and is higher in women, while ASI has a positive relationship with age and SBP. In patients with hypertension and coronary artery disease, there is a positive correlation between male body mass index and PWVao. The increase in ASI in this group is associated with female gender, SBP and age. In individuals without hypertension and signs of atherosclerosis with a family history of CVD, PWVao values are higher than in similar individuals without a family history of CVD.
CONCLUSIONS: In the group of all the participants, female gender, smoking, an older age, SBP, and body mass index are associated with increased AS parameters. The association between risk factors and parameters of arterial stiffness has peculiarities in patients with hypertension with varying degrees of severity of the atherosclerotic process.

Teruel, región devastada: Estrategias de supervivencia, muerte y reconstrucción comunitaria en la posguerra, 1938-1953
Authors: Alegre David
Published: June 2022

La mitad suroccidental de la provincia de Teruel constituye un escenario excepcional para entender las particularidades de la vida cotidiana de posguerra en territorios afectados por un conflicto moderno. Las herramientas de la historia sociocultural de la guerra nos permiten observar que la población de la capital y su entorno más inmediato enfrentó una crisis humanitaria gravísima durante la década posterior a los enfrentamientos armados. Esta estuvo directamente relacionada con los múltiples efectos que el conflicto dejó tras de sí, y se vio agravada por las políticas de un régimen dictatorial en construcción. El análisis de la documentación generada por los juzgados de instrucción locales y el Gobierno Civil, cruzado con los testimonios de algunos contemporáneos, pone de manifiesto cómo se articuló el proceso de reconstrucción de la vida en comunidad y el tipo de estrategias al que tuvieron que recurrir los autóctonos para sobrevivir. Todo ello nos sitúa ante las particulares consecuencias sociales y económicas de la guerra en Teruel: contaminación, accidentes causados por la chatarra de guerra, trabajo infantil, pobreza extrema, hurtos y robos de subsistencia, inseguridad ciudadana, abusos de poder y desobediencia, marginación social, suicidios y afecciones mentales.
De la escuela de Granada al “clan mudéjar”: supervivencia académica y viraje intelectual de los discípulos de Fernando de los Ríos en el primer franquismo (1936-1953)
Authors: San Andrés Corral Javier
Published: June 2022

Desde el comienzo de la Guerra Civil, la depuración emprendida por los sublevados contra los intelectuales republicanos o renovadores puso fin a la edad de plata de la cultura española. La dictadura, sin embargo, no pudo erradicar del todo la tradición intelectual precedente, que subsistió en algunos discípulos de los intelectuales represaliados, oculta tras la adhesión de muchos de ellos al nuevo Estado. Este trabajo analiza las relaciones entre los intelectuales y la dictadura, a partir de las trayectorias de Enrique Gómez Arboleya y Nicolás Ramiro Rico, discípulos de Fernando de los Ríos. Ambos asumieron posiciones complacientes con la dictadura, se integraron en las redes académicas creadas en la guerra o en la posguerra, participaron en la construcción de la cultura jurídica de los vencedores y se desvincularon de su maestro, aunque no se desprendieron del todo de su herencia intelectual y científica, que los llevó a cultivar una teoría jurídica y política de vocación sociológica y a distanciarse del franquismo en los cincuenta. El estudio se basa en el análisis de sus producciones y sus ejercicios de oposiciones a cátedras de Filosofía del Derecho, Derecho Político y Sociología entre 1940 y 1953.
Medios de comunicación y utopía autoritaria: la Secretaría de Difusión y Turismo. Argentina, 1967-1969
Authors: Ramírez Llorens Fernando Matías
Published: June 2022

La Secretaría de Difusión y Turismo (SDT) fue la política oficial de medios argentina más ambiciosa desde la época del primer peronismo. En este trabajo se reconstruyen los aspectos principales de esta experiencia olvidada por la historiografía, a partir del estudio de publicaciones periodísticas de la época, entre otras fuentes orales y escritas consultadas. La intención es comprender el objetivo general perseguido por la política comunicacional de la dictadura del general Onganía y aportar al conocimiento de los vínculos que se traman entre proyectos políticos autoritarios y medios de comunicación. El trabajo parte de la hipótesis de que el proyecto de la SDT se propuso una reestructuración de todo el sistema de medios (estatal y privado), orientado a dar sustento a una dictadura que intentó administrar desde arriba los tiempos de la política económica y social y de la participación política. De manera complementaria, la SDT se propuso construir una imagen de la dictadura argentina en el exterior, que presentase de manera positiva a una población de costumbres liberales que producían y consumían sin censura todo tipo de bienes culturales. El artículo presenta los límites y contradicciones que experimentó esta política, pero destaca su carácter fundacional en términos de consolidar la actuación del Estado en medios, una lógica que se continuaría en la dictadura y postdictadura de las siguientes dos décadas.

Published: June 2022

The description of sound as a form of energetic pollutant is very complex as is also its impact on aquatic life. Human activities causing continuous and implosive underwater noise, such as marine traffic, maintenance of ships, coastal tourism, marine research, military, offshore energy platforms, generation of ocean energies and construction operations are expected to increase. The paper analyses current approach to minimise the impact of underwater noise and limit its emissions, examines regulatory approach and discusses the possibilities to control this type of pollution in order to ensure the preservation of natural underwater soundscape. The timely implementation and further development of the European Marine Strategy Framework Directive and its provisions related to underwater noise is of exceptional importance for the Adriatic Sea, which is facing increasing pressure from various industries generating underwater noise.

Authors: Holjević Toni , Travaš Vanja , Kranjčević Lado , Družeta Siniša
Published: June 2022

The progressive increase in the mass of microplastics in the ecosystem obliges us to urgently define measures to reduce its adverse effects, which primarily requires an understanding of the genesis of its presence and the dynamics of expansion through the biosphere. This paper aims to contribute to the understanding of the dynamics of microplastic particle motion, especially in the context of deposition rate with respect to microplastic material density, microplastic particle size and especially with respect to microplastic particle shape (which significantly affects shape resistance forces). For this purpose, an overview of existing works in the field of modeling the motion of microplastics is given, and a numerical model for modeling the transport of microplastic particles in an inhomogeneous fluid velocity field for laminar flow is formed. The proposed model is thus based on a system of two nonlinear ordinary differential equations.

Authors: Pelić Vladimir , Mrakovčić Tomislav , Radonja Radoslav , Račić Nikola
Published: June 2022

A ship's propulsion system has a significant impact on the ship’s energy efficiency, environmental friendliness, reliability and safety. An indispensable part of a propulsion system with mechanical power transmission is a stern tube with bearings. During operation, the sliding bearings material is subjected to stresses caused by a force proportional to the total mass of the shaft and propeller. The reliability of stern tube bearings is particulary important for safety, and their durability has a significant impact on maintenance costs. Depending on the lubricant, there are bearings that are lubricated with oil or water. The permissible bearing load with hydrodynamic lubrication depends primarily on the material, the viscosity of the lubricant used and the shaft speed. Metals and their alloys with a low coefficient of friction are used for oil-lubricated bearings. Bearings lubricated with water are made of a special type of hardwood ("tree of life", lat. lignum vitae), rubber or various synthetic materials. The main advantages of oil-lubricated bearings are higher allowable load and durability than water-lubricated bearings. This paper analyses the technical and environmental aspects of the application of water-lubricated bearings whose main advantages are simplicity, better cooling and environmental protection.

Published: June 2022

In this paper, the methodology of seaworthiness and stability analysis of a pontoon for holiday house has described. A 3D model of the pontoon was modelled in the NAPA software to perform hydrostatic analysis. It is necessary to emphasize the fact that hydrostatic analysis has been made for several drafts and trims of pontoons. The hydrostatic analysis yielded data such as displacement, moulded volume, longitudinal centre of buoyancy, the transverse metacentric height, change of displacement, moment to change trim, and more. This part of the analysis also includes the loading scale from which we can see the deadweight at a given draft. Further, it is necessary to make weight study to get moulded displacement for pontoon for a holiday house. The pontoon also includes capacity tanks, so it is necessary to know the accurate dimensions of the tanks and their position for further analysis. It is necessary to know the exact geometry of the tanks because of the free surface effect. When calculating the stability of the pontoon, it is necessary to determine the minimum metacentric height and the maximum distance from the keel to the centre of gravity. Intact stability conditions must be met for GM limit curves and also for KG curves. Intact stability criteria of the pontoon were tested for four loading conditions: lightship, pontoon with 10% consumables without passengers, pontoon with 100% consumables with passengers, pontoon with 50% consumables with passengers. It is important to emphasize that all tasks meet the stability criteria.
Comparison Between the Classical Method of Inclining Experiment with the Recent Alternative Methods
Authors: Radoš Lovro , Turk Anton , Legović Dunja
Published: June 2022

The classical method of inclining experiments has been used to determine the position of the ship's vertical center of gravity for many years. The method contains some basic assumptions, which is why the accuracy of the method has been debated in the last few years. Modern ships often have chines, or pronounced flare at fore and aft extremities, that can lead to a significant change in the waterline. The position of the metacenter changes on these ships as they incline. Therefore, the calculation of the ship's center of gravity by the classical method may be inaccurate.

In this paper, three different methods that are not based on the assumption of an unchanged metacenter are examined. Using a graphical, polar, and general method, the position of the ship's center of gravity system can be determined for any ship without determining the position of the metacenter. The three methods mentioned in this paper were observed and tested on four different ships. In addition, the results of the classical method are compared with the results obtained from recently developed methods
A low dose of amiodarone-indused sinoatrial node dysfunction: a case report
Authors: Ayurzana A. , Avirmed A. , Avarzed A. , Batkhuu B. , Amgalanbaatar D.
Published: June 2022

We recently treated a case similar to that reported by Mun et al and Chinushi M. Holter ECG demonstrated paroxysmal atrial fibrillation, frequent ventricular ectopy’s, atrial tachycardia. The patient complained of palpitation. We have prescribed and amiodarone (100 mg/day) per day for 2 months. In the second visit, the palpitation attacks were relieved. It was effective in decreasing palpitation and atrial fibrillation. However, the patient was readmitted because of a new complaint of feeling weak, dizziness, confusion, and fainting. Holter monitoring revealed a long sinus pause (4–7,9 seconds). Because such a sinus pause had not been observed before the amiodarone treatment, it is likely that the development of sick sinus syndrome was related to amiodarone. Therefore, it seems inappropriate to apply this incidence of amiodarone-related sinoatrial node dysfunction to patients who are prescribed amiodarone for the treatment of ventricular tachyarrhythmia and atrial fibrillation who have prescribed a lower maintenance dose of amiodarone.

There is conflicting data regarding the difference between automated and manual processing of gated myocardial SPECT images. The purpose of this retrospective “cross-sectional study is to compare the degree of variability between automated and manual processing of Quantitative Gated SPECT algorithms for assessing left ventricular volumes and ejection percent”. Study was carried out in the Nuclear Medicine department “at the Security Forces Hospital, Riyadh, Saudi Arabia, and comprised of 96 participants who “underwent” both stress and “rest gated” myocardial perfusion “imaging” (MPI) from February to May 2021. Data were analyzed “using SPSS for Windows (version 22; IBM Corp., Armonk, NY, USA). The mean of EF, ESV, and EDV on stress test using the automatic technique were 62.46 ± 14.62%, 45.00 ± 37.10 ml, and 107.01 ± 43.70 ml, respectively while using the manual technique were 57.21±14.80%, 44.35±35.93 ml, and 93.26±39.14 ml, respectively. The mean of EF, ESV, and EDV on rest test using the automatic technique were 62.85± 15.47%, 43.44± 36.35 ml, and 104.27±42.51 ml, respectively while using the manual technique were 57.74±15.33%, 43.30±36.42 ml, and 91.72±41.50 ml, respectively. For LVEF and EDV, the difference between automated and manual techniques is statistically significant (p<0.05). However, no “statistically significant difference” exists between automated and manual ESV techniques (p>0.05). Discrepancies were observed that exist by using the fully automated and manual technique for determining LVEF and Left ventricular volumes by gated MPI.

Behavioral shift of generation X towards OTT during Covid’19 in India
Authors: Sridhar S. , Phadtare P.
Published: June 2022

Over-the-top (OTT) services such as Netflix, Prime Video, Disney+ Hotstar, Zee5, etc., have changed consumers’ content consumption behavior. Globalization and Digitalization have encouraged consumers to have limitless access to the Internet for information, leisure, entertainment, and social interconnectedness. The increase in the availability of high-speed Internet, the latest smartphones, and breakthroughs in technology have created great opportunities for the OTT sector, with people preferring to consume content on-the-go digitally rather than traditional media services, such as cable television. The Covid’19 pandemic has seen an increase in viewership’s and subscriptions towards these streaming platforms, with people of different age groups adapting to changing viewership trends. This study aims to understand Generation X’s behavioral shift (Age 41 to 55) towards OTT during Covid’19 in India. The literature review talks about the Generation X cohort of consumers, their behavioral habits, and attitudes towards technology. It also discusses the changing trends of online content consumption and how Covid’19 has created a spark in viewership’s towards India’s online media services. The research study aims to perform explanatory research to establish a relationship between the increase in consumption and subscriptions of OTT services in India by Generation X and the impact of Covid’19 on the same. Data will be collected from consumer’s age amongst 41 to 55 in India via survey questionnaires, and linear regression tests will be performed to test the hypotheses and establish a correlation between the dependent and independent variables.

On models of chronic neurogenic pain (CNP) and the growth of a malignant tumor (metastasizing B16 melanoma) in male mice, we studied an effect produced by mitochondrial therapy (MCT) on the state of the myocardium. Some structural correlates of the compensatory-restorative effect by mitochondria transplanted from healthy recipient rats were revealed. It has been identified that MCT contributes to the preservation of the structural integrity of the myocardial tissue, the inclusion of an auxiliary link in the cellular mechanisms of tissue restoration: fibroblasts, histiocytes, lymphocytes, eosinophils and other connective tissue elements, which implement the intercellular mechanism of information transfer that provides the external regulatory function of MCT. The ability of mitochondria to prevent the DNA decay determines the possibility of initiation of the operation of the nuclear mechanisms of the cardiomyocyte division, which is characteristic of a population of young cells and which indicates the determining position of exogenous mitochondria.

Obsessive-compulsive disorder frequently have insomnia, and those with acute insomnia who also have mental comorbidities without therapy, they are more likely to develop persistent insomnia. We present a case of OCD with acute insomnia that was successfully treated with early non-pharmacological sleep psychiatry intervention. Sleep is necessary for brain function and the maintenance of cognitive and emotional processes. Insomnia and anxiety problems are common, and they’re linked to a lot of damage and disability. In addition to being strongly comorbid with major depressive illness, there is evidence that sleeplessness and anxiety disorders frequently co-occur. The majority of insomnia psychological therapies include sleep hygiene. In terms of clinical practice, these instructions are a solid place to start. Obsessive-compulsive disorder is associated with sleep difficulties. Sleep difficulties are also common in people with obsessive-compulsive disorder, with up to 48% reporting them. Obsessive compulsive disorder research reveals a link between specific sleep habits and clinical factors such the severity of obsessive-compulsive symptoms, treatment resistance, and the age at which the disorder.

Published: June 2022

The main aim of the paper is to develop an early detection system for glaucoma classification using the fundus images. By reviewing the various glaucoma image classification schemes, suitable features and supervised approaches are identified. An automated Computer Aided Diagnosis (CAD) system is developed for glaucoma based on soft computing techniques. It consists of three stages. The Region Of Interest (ROI) is selected in the first stage that comprises of Optic Disc (OD) region only. It is selected automatically based on the on the green channel’s highest intensity. In the second stage, features such as colour and Local Binary patterns (LBP) are extracted. In the final stage, classification of fundus image is achieved by employing supervised learning of Support Vector Machine (SVM) classifier for classifying the fundus images into either normal or glaucomatous. The evaluation of the CAD system on four public databases; ORIGA, RIM-ONE, DRISHTI-GS, and HRF show that LBP gives promising results than the conventional colour features.

The precocious knowledge on reckoning schemes scientifically and technically was replaced with the rapid amelioration in medicinal contrivance systems and treatment information registers. On average the management accomplishes hospital information system (HIS) and picture archiving and communication systems (PACS) using digital entities to maintain medical examinations, images and statements. Such systems even though are much helpful for the hospital staff, doctor away from the hospital have lot of difficulty to access the patient data during risk facing situations. To iron out the above-mentioned complications, a new idea of the proposed framework has been disseminated for medical descriptions to the doctors at inaccessible areas. This organization requires a hand-hand PDA’s that adopts CDMA techniques with mobile networks. This arrangement requires a server and PDA for its implementation. This model supports the entire reports of the patient to the doctors located even at remote location with accessibility and doctor information reliable for patients. PDA created will disclose the inmate’s medicinal reports and scans over an outlying network. To corroborate or validate user data, remote data approach is applied by PDA that connects the server directory and for relegation of information from the server, uses file transfer protocol. From testing, observations show ninety seconds to convey thirty images with a fineness of 832 x 488, intensity of 24 bits and magnitude of 0.37 Mb. This idea proposed using bitmap image acquiring technique demonstrates no difficulty for distant doctors to collect and examine the sufferer images right away at the time of crisis or urgencies, which is completely subjective analysis based on doctor’s point of view.
