Authors: Hasna Salsabila
Published: April 2023

Pancasila in environmental sustainability discusses how to preserve the environment and the laws contained in the Act that are in accordance with the practice of Pancasila. In Indonesia alone there are many problems that occur especially regarding environmental pollution and environmental destruction which causes inconvenience to some people in the environment. Legally regulated about environmental management. In every precept in the Pancasila, various applications and practices of the community have been regulated in addressing this already polluted environment. Indonesian citizens in particular, must be able to carry out the mandate that the environment is a shared environment, meaning that they must participate in preserving the environment so that it is not polluted by undesirable things. The most needed thing in carrying out this mandate is one of them is public awareness in preserving the environment. Awareness is very important because it can change the perspective of one human being with another. Various efforts have been made by the government and citizens to preserve the environment and manage the environment efficiently.
The Effect of Globalization on the Ideology of Pancasila
Authors: Kurniasih Ria
Published: April 2023

Pancasila is often seen as an ideology that deals with global ideologies, such as capitalism and liberalism. The Pancasila that was built was for the common welfare and social justice for all Indonesian people. On the other hand, we live in a globalization that is full of laws and rules of capitalism, free and open markets. We must remain firm and strong in our stance, that we will continue to dedicate all of these things to the common good, to social justice. An intelligent nation in the era of globalization, is not a nation that continues to complain, give up, and get angry, but a nation that is able to drain the sources of prosperity available in the global arena. We all use technology, capital or information properly to improve our welfare and interests. Don't want to be the loser. Let's be winners in this globalization. Globalization is an era of rapid changes that contain positive things, but also brings negative aspects for the Indonesian people. The Indonesian people must be good at seizing and taking advantage of opportunities from the positive aspects and still standing on the values that have been pledged, defended, and upheld. Facing globalization, the Indonesian nation must be able to stand up by having sovereignty in the political field, independence in the economy, personality in culture, and having strong resilience in national security. More than that, we must continue to strengthen our identity as Pancasilaists who uphold the 1945 Constitution of the Republic of Indonesia and strengthen the establishment of the Unitary State of the Republic of Indonesia. Every citizen is obliged to defend his country so that the survival of his nation is maintained. To defend the country is largely determined by the attitudes and behavior of every citizen. If citizens are active and care about the progress of their nation, the survival of the nation will be maintained. It is better if citizens do not care about the problems facing their nation, the survival of the nation will be threatened and sooner or later the state will dissolve.
How does Pancasila work in countering radicalism and terrorism in Indonesia?
Authors: Ariyani Sri Dewi
Published: April 2023

Pancasila is a solution to the problems of radicalism that have hit Indonesia today. Then it is hoped that the values in Pancasila must be truly carried out by the Indonesian people to prevent and minimize radicalism and terrorism in our beloved country. The loss of values contained in Pancasila in Indonesian society is the basis of the emergence of various acts of radicalism terrorism in Indonesia. Therefore, the implementation of Pancasila values, in order to remain current in the face of the threat of radicalism must be emphasized in the delivery of the following three messages: 1. This country is formed based on agreement and equality, in which no one should feel as a major shareholder, or first class citizen. 2. Rules for playing in a state have been agreed upon, and the State has full sovereignty to bring order to the members of its country who try systematically to change the order, in ways that are against the law. 3. The state provides protection, opportunity, future and balanced protection to achieve the national goals of a just and prosperous society, prosperous, safe, civilized and free.           The Indonesian government recently began to be aware of the development of radicalism in the country related to the ISIS network (the Islamic State of Iraq and Syria). This issue about ISIS has become a global issue and it seems the world is compact to fight it. Seeing this phenomenon, there needs to be steps to prevent acts of radicalism from flourishing on the earth. In addition to taking action on radicalism, the government must also prevent or preventive measures so that people are not easily provoked against ideologies that use religious attributes. Close collaboration between the government, security forces and religious leaders is needed to rectify religious understanding.
The Challenge of Pancasila in the Development of the Millennial Generation
Authors: Aimana Salwa Nadiyah
Published: April 2023

The Indonesian nation has a unifying tool for the nation which is formed from the noble values of Indonesia. In the era of the Majapahit kingdom, in the book Sutasoma by Mpu Tantular it is written "Bhineka Tunggal Ika, Tan Hana Dharma Mangrwa" which tells that at that time there were no disputes caused by differences caused by differences in religion or ethnicity. This proves that respect for differences has been believed by the ancestors of the Indonesian people since hundreds of years ago. Therefore, it is very unfortunate if the history of harmony in the Indonesian nation, which has been hundreds of years, has to be destroyed by hatred caused by greed and the struggle for power by certain groups. In the millennial era, technological developments are far more advanced with various existing developments. Along with the times, information is more easily accessible in various parts of the world. Everyone can access any information from any country with the international system. Everyone cannot avoid technological developments that are always there and change all the time. Communication and information technology has changed conventional wars into modern wars using technology, mass media, the internet and the targets are economic resilience, defense and security, culture, ideology, environment, politics, and character.

Authors: Ula Alannur Fajril
Published: April 2023

The use of social media used in learning Pancasila Education courses for the development of the millennial generation is very much needed and needed. Learning Pancasila Education which is generally static, critical, boring and tends to be more rote which actually makes many students less interested and even not interested at all in studying and deepening the knowledge of Pancasila Education. As young people, students must be given a touch of interesting and not boring Pancasila Education learning by utilizing social media such as YouTube, Instagram, Facebook and vlogs. To make learning Pancasila Education fun and interactive, the lecturer can give the task of making a creative and innovative work based on social media. The use of social media will make the millennial generation learn Pancasila Education in the form of theory and reality, will bring creativity in learning. It is hoped that the Pancasila Education learning using social media can create interactive, fun, relevant learning to everyday life and able to adapt to the character of the millennial generation that is connected to technological developments and advances. Pancasila Education Learning finally runs in an atmosphere that is not boring with material that includes a study of several existing theories and realities so that they are able to adapt to the times.
Participation of Judicial Decisions as the Form of the Implementation of Moral Values in Case Statement Based on Recht Vinding Activities and the Theorie of Negative Opening (Negative Wetjlike Theorie)
Authors: Zikra Ikhda
Published: April 2023

The judge is the spearhead as well as the parameter of justice test conducted by the justice seekers. One of them through decisions issued by the judge, many things that need to be considered and considered by the judge in deciding a case, especially because the justice is universal and the science of law which is a science that is multidisciplinary means not monotonous or only limited to eyeglasses or juridical point of view only but need to pay attention to other values that live, grow, and develop in society both written and written. Article 16 and 28 of Law Number 4 Year 2004 as already amended into Law mandates that judges are prohibited from refusing cases that enter the Court under the pretext that the law does not regulate, it is unclear but is obliged to examine and decide upon the case. Then in article 28 explained that the judge must dig the values that exist in society. This is to ensure a sense of justice for the community because the law is not what is contained in the law alone but also pay attention to other laws that are Living Law and Unwritten Law in the form of habits that exist in society, customs, or traditions is still acknowledged and lives, grows, and develops with the community based on the mandate of Pancasila and the Constitution of the Republic of Indonesia which is accommodated in Article 18 B Paragraph (2) that "the state recognizes and respects the unity of society as long as it exists within the community" in its legal considerations shall explore and include these values for the implementation of social justice for all Indonesian people. So the judge's conviction in deciding a case also greatly affects the content of the decision so as not to negate the existing morality as a unity of values that live and grow in society. HLA Hart acknowledges that law and morals have a very close relationship, even Hart reveals that between law, justice and morality has a very close relationship, even one of the aspects of justice, namely administrative justice, in the law of the minimum nature of law and morality is the absolute relationship.
Covid-19 Pandemic Force Majeure (Overmacth) in Agreements as a Form of Legal Guarantee
Authors: Payuwaha Bakhitabiyya Ridya
Published: April 2023

The Covid-19 pandemic is a national disaster and has even become a non-natural international disaster that almost all countries have experienced. The Covid-19 pandemic is used as a force majeure reason for the cancellation of an agreement or forced circumstances. Related to this research is a normative juridical research based on several norms and applicable laws. The method used is a conceptual approach in legal research that provides an analytical perspective on problem solving by looking at the background of legal concepts and looking at the values contained in the applicable norms. Legal certainty is needed regarding these problems as the form of legal certainty is a strong basis for legal guidelines for the community. The Covid-19 pandemic can be used as a force majeure reason for the cancellation of an agreement, referring to Article 1245 of the Civil Code which states that the debtor does not need to reimburse costs, losses, and interest, because the achievements in the agreement are not fulfilled due to compelling circumstances. Regarding this matter, legal certainty for people affected by this regulation, basically the cancellation of the agreement due to force majeure or coercive circumstances refers to the existing statutory regulations.
Las mujeres de Marienthal.
Authors: Villalba Gómez Daniel
Published: April 2023

Supone un imperativo para la historia realizar una revisión del papel de las mujeres durante la crisis que golpeó Europa a principios de la década de 1930. Bajo tal premisa, este artículo se centra concretamente en la población femenina de la localidad industrial austriaca de Marienthal. De ahí que se reinterpreten los datos del célebre estudio sociográfico sobre los “parados” publicado por Marie Jahoda, Paul Felix Lazarsfeld y Hans Zeisel, desmontando los códigos analíticos patriarcales que lo estructuran. Por consiguiente, se analizan los efectos del desempleo sobre ellas en torno a tres ejes: la gestión económica doméstica, la noción de tiempo y las afecciones psicológicas y, por último, el maltrato de género en los matrimonios.

Neither oblivion nor reconciliation. An analysis of post-Francoist Spanish historical memory and Transitional Justice
Authors: Escobar Fernández Ivan
Published: April 2023

Authoritarian regimes seek their preservation through the systematic repression of any dissidence, leading to the perpetration of crimes against anyone who might challenge the regime's values and legitimacy. Thus, when transitioning from an authoritarian regime to a democratic system, implementing a comprehensive transitional justice process is imperative to close old wounds and ensure reconciliation and reparation between the parties. Francoism, like every authoritarian regime, was not exempt from committing serious crimes against its enemies for more than three decades. Nonetheless, when Spain transitioned from a dictatorial to a democratic model, democratization was prioritized over justice. Despite the Spanish reluctance to adopt all necessary transitional justice measures during the democratization process, the Spanish Transition has been claimed to be an exemplary case to follow and study. This article aims to overview the three legal documents that were supposed to guarantee transitional justice to the victims and the Spanish society: the 1977 Amnesty Law, the 2007 Historical Memory Law, and the recently passed 2022 Law of Democratic Memory. This article concludes that although the 2022 Law of Democratic Memory has solved some of the flaws of previous legislation, there are still some key aspects of transitional justice which remain unaddressed.

Authors: Sadeghifar Hasan , Venditti Richard , Pawlak Joel J. , Jur Jesse
Published: April 2023

Cellulose transparent and flexible film was prepared by dissolving micro-crystalline cellulose powder in Dimethylacetamide/Lithium Chloride (DMAc/LiCl) followed by regeneration in acetone and subsequent washing with water. The solution was cast on a glass plate. The interactions of water molecules and the swollen cellulose in the gel were examined by differential scanning calorimetry, DSC. An increased melting point of water in the gel indicated the presence of stronger bonding between water and cellulose than in the non-modified cellulose. The prepared dried films had 63 g/m2 weight and 0.06 mm thickness with 1.14 g/cm3 density.The prepared dry film exhibited high transparency, around 95% with visible light. The transparency and mechanical properties of the films were stable at high temperature (120°C) and exposure to UV irradiation. Thermal analysis of the prepared sample indicated film stability up to 275 °C. The tensile strength of the cellulose film was around 120 MPa with about 10% strain to break. The mechanical properties of the films were stable in alkali and acidic solutions.
Key Mechanical Properties of Cross-banded Laminated Veneer Lumbers Manufactured from Blending Spotted Gum and Hoop Pine Veneers
Authors: Nguyen Hoan Hai , McGavin Robert Lee , Gilbert Benoit P. , Bailleres Henri
Published: April 2023

The main objective of this study was to investigate the key mechanical properties of cross-banded laminated veneer lumbers (LVL-C) manufactured from blending veneers recovered from sub-optimal native forest spotted gum and plantation hoop pine logs. The recovered veneers were separated into three grades based on their dynamic modulus of elasticity (MOE). Additionally, the spotted gum veneers were visually graded to evaluate whether a relationship exists between the MOE-based and visual grades. In total, six 12-ply reference LVL and six mixed-species 12-ply LVL-C panels were manufactured and analyzed for (i) flatwise and edgewise bending performance; (ii) bearing and tension strength perpendicular to the grain; and (iii) longitudinal-tangential shear strength. Little correlation was found between MOE-based and visual grades for the spotted gum veneers. The LVL- C showed flatwise and edgewise MOE up to 24% and 13% lower, respectively, than the reference mixed-species LVL. The flatwise and edgewise modulus of rupture were up to 39% and 19% lower, respectively. On average, the tensile and bearing strengths of the LVL-C were considerably higher than the hoop pine LVL and mixed-species LVL, with the former being approximately three times higher. The manufactured LVL-C showed markedly higher bending properties and tensile strengths than commercial LVL-C products.
Ultimate direct withdrawal loads of low shear strength wooden dowels in selected wood species for furniture applications
Authors: Chen Chen , Xing Yan , Xu Wei , Tor Onder , Quin Franklin , Zhang Jilei
Published: April 2023

The wood dowel pin is one of the common fasteners for connecting structural members in wooden furniture frame construction, such as chairs. The effects of dowel penetration depth, shear strengths of connection member and dowel materials, dowel surface texture, and member grain orientation on ultimate direct withdrawal loads of single dowels withdrawn from wooden materials were investigated. The main findings were that the connections using dowels and main members with low shear strength properties achieved the same ultimate direct withdrawal loads with connections using the materials with higher shear strength properties for dowels and main members. Additionally, the existing empirical equations, including shear strength properties for both dowel and main member materials used to construct dowel connections, tended to remarkably underestimate the ultimate direct withdrawal loads of the evaluated dowel connections withdrawn from the end and side grains of the tested wood species. The connection main members in this study when these two shear strength values were added together was less than 25 MPa. Both estimation expressions were modified to consider the lower shear strength effort on ultimate direct withdrawal loads of dowels evaluated in this experiment.
Application of cellulosic fiber in soil erosion mitigation: Prospect and challenges
Authors: Syakir M. I. , Al Manasir Yazan , Nor Ashikin Nurin Syahindah Syasya , Yusuff Shaiful , Zuknik Mark , Abdul Khalil H. P. S.
Published: April 2023

The agricultural industry is one of the main economic contributors in developing countries, especially in tropical regions. Extensive land clearing has led to severe erosion within the watersheds, which increases the vulnerability of water catchments to natural disasters, such as floods. Cellulosic fibers, such as jute, sisal, kenaf, hemp, and coir, are gaining increasing worldwide attention for their potential application in controlling soil erosion, principally due to their remarkable biodegradable and physical properties. Nonetheless, the research on biocomposites in controlling soil erosion is limited compared to the natural fibers. This is perhaps due to poor availability and high cost of biodegradable polymers compared to natural fibers, which are abundant and inexpensive. Poor adhesive interactions between the matrix and natural fibers due to the hydrophilic characteristic of the fibers is another major drawback that limits the development of biocomposites for controlling soil erosion.

Biological studies of Puccinia lantanae, a potential biocontrol agent of “Lippia” (Phyla nodiflora var. minor)
Authors: Traversa Guadalupe , Sosa Alejandro Joaquín , Chantre Guillermo Rubén , Bianchinotti Maria Virginia
Published: April 2023

Phyla nodiflora var. minor (syn. P. canescens (Kunth) Greene) known as “lippia” is an invasive weed with considerable impact on agricultural systems and conservation areas in Australia. The rust fungus Puccinia lantanae Farl. has been proposed as a potential biocontrol agent of Lantana camara. As it was previously found in Lippia s.l. in Argentina, we aim to study: (i) its geographical distribution in Argentina, Bolivia, and Chile; (ii) teliospore germination and basidiospore formation under different incubation temperatures; (iii) the effect of teliospore age on germination capacity; (iv) the effect of heat shock on teliospore germination and basidiospore formation; and (v) the pathogenicity of the rust fungus on P. nodiflora. Field surveys were conducted in Argentina, Bolivia, and Chile. In vitro experimental assays of germination and pathogenicity were performed. The rust was found in four provinces of Argentina (Jujuy, Salta, Formosa, and Entre Rios) and was not found in Bolivia and Chile. Puccinia lantanae showed the maximum values of teliospore germination and basidiospore formation at 20°C. The effect of aging and heat shock treatments significantly reduced teliospore germination. Pathogenicity tests showed that P. nodiflora var. minor, reptans, and nodiflora were infected with the “Formosa” isolate. The isolates “Salta” and “Entre Rios” infected var. minor and reptans, being potential candidates for biocontrol.

Published: April 2023

The aim of the study was to evaluate in vitro antioxidant and antifungal activities of the ethanolic extract and its fractions from Ocimum gratissimum leaves. The ethanolic extract was obtained by maceration in ethanol and subsequent fractionation with solvents of increasing polarity (hexane, dichloromethane, ethyl acetate and butanol). The Minimum Inhibitory Concentration (MIC) was determined for the ethanol extract and dichloromethane fraction. The antioxidant capacity was evaluated by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) and ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) free radical scavenging methods, and by FRAP (Ferric Reducing Antioxidant Power). The in vitro antifungal effect was determined by the agar diffusion method on Aspergillus sp. and Rhizopus sp. fungi associated with corn and bean seeds during storage. The best samples with antifungal effect were determined by gas chromatography-mass spectrometry (GC/MS). The ethanolic extract had strong antioxidant capacity for all tested methods (DPPH 371.10±2.98 μg ml-1, ABTS 182.43±1.10 μg ml-1, FRAP 262.39±3.61 TEAC). Regarding the antifungal activity, the ethanolic extract and dichloromethane fraction resulted in total suppression (100%) of fungal growth and MIC ranged from 0.625 to 1.25 mg ml-1. In the GC/MS analysis, 22 substances were detected in all samples evaluated, with predominance of eugenol. These results indicated high biological potential of this plant as a biofungicide

A new solution for control of respiratory infection by Streptococcus equi isolated from horses in northern Iran
Authors: Yaghoobpour M. , Fozouni L. , Ghaemi P.
Published: April 2023

Respiratory infections caused by Streptococcus equi are one of the most important diseases in the equine industry. The increasing rate of antibiotic resistance among this bacterial species necessitates new antimicrobial agents. In this research, nasopharyngeal samples were taken from horses (n=90) in some areas of the Golestan Province, Iran. After isolation and identification of S. equi strains, antibiotic resistance of the isolates was evaluated using the Kirby-Bauer method. The antibacterial effect of lavender essential oil was investigated by broth microdilution assay. The frequency of streptococcal strains was 27.8%. The most frequent isolates were S. equi subsp. equi (72%) and S. equi subsp. zooepidemicus (28%). The frequency of S. equi was highest in horses aged less than 2 years (69.3%) and thoroughbred Turkmen horses (61.5%). The highest rate of resistance was observed against amoxicillin, while the highest rate of sensitivity was to ceftriaxone. Furthermore, the essential oil of lavender inhibited 90% of the isolates at concentrations ≥2048 μL/mL. Our study revealed that the frequency of antibiotic-resistant S. equi isolates was relatively high in the studied population of horses in Iran. It was concluded that essential oil of lavender possessed more potent in vitro activity than the common antibiotics for treatment of infections caused by S. equi subspecies.

Monitoring of histamine-induced calcium channel activity of a single cell using semiconducting carbon nanotube transistors
Authors: Ngoc Pham Van Bach , Pham Ba Viet Anh , Nguyen Viet Khoa
Published: April 2023

A method using transistors based on semiconducting carbon nanotubes were developed for the real-time monitoring of the electrophysiological responses of individual cells to histamine stimulation. Transistors with one or three floating electrodes were utilized to evaluate histamine-induced Ca2+ influx into Hela cells via the recording of the conductance changes of the transistors. The Ca2+ influx resulted from the activation of histamine H1 receptors embedded on the cell membranes by histamine, which generated a temporary negative potential at the gap between the cell and the transistor. Moreover, the antihistamine effects of chlorpheniramine on histamine-induced Ca2+ influx were also investigated by using a transistor including three floating electrodes. Especially, only a single transistor was applied to repeat the measurements of the responses of multiple Hela cells pretreated with chlorpheniramine to histamine stimulation. This allows us to acquire data without being suffered from device-to-device variations, implying our method would be a simple but powerful method for applications of nanoscale biosensors to electrophysiological studies.

Research data were collected from retrospective reflections and stimulated recall with ten PSTs. Deploying Hargreaves’ (2001a) emotional geography, the research sought to portray PSTs’ emotional understandings and misunderstandings resulting from the engagement with school community. This study also examined PSTs’ emotion regulation strategies, as the orchestra to construct and re-construct their belief, skills, and professional identity. The findings document contoured emotional experiences characterized by three major themes, inter alia (dis)engagement, (dis)orientation, and distress; personal support and social acceptance; and compliance, cooperation, and completion. PSTs resort to antecedent-focused strategies to cope with the emotional dilemma due to their contextual relevance, effectiveness, and their peripherality in the school community. The research implication substantiates the need for restructuring the policy and practice of teaching practicum to accrue an exemplary foundation for teacher education.
HIV infection and cardiovascular pathology

Published: April 2023

According to modern literature data, the role of human immunodeficiency virus (HIV) infection has been proven as an independent risk factor (RF) for atherosclerosis and cardiovascular diseases (CVDs), including coronary artery disease, heart failure, and sudden cardiac death. The role of antiretroviral therapy (ART) in the occurrence of CVD remains debatable. On the one hand, ART is a mandatory component in CVD prevention, since there are numerous confirmations of the association of high viral load and noncompensated immune status with an increased risk of CVD. On the other hand, the use of certain classes of ART agents is associated with the development of dyslipidemia, insulin resistance, and type 2 diabetes, which are risk factors for CVD. In this regard, the current HIV treatment protocols require an assessment of CVD risk factors to select the optimal ART regimen. It must be remembered that when using generally accepted algorithms and scales for assessing the risk of CVD, the real risk may remain underestimated in HIV-infected patients. This literature review presents a patient data management algorithm developed by the American Heart Association and describes statin therapy in patients with HIV infection.
Combined effect of sedentary behavior and physical activity of different intensity on cardiovascular health
Authors: Loginov S. I.
Published: April 2023

Sedentary behavior (SB) and low (insufficient) physical activity (LPA) are two complementary negative factors affecting cardiovascular health. Most of the current studies are devoted to the study of SB and physical activity (PA) of different intensity separately, while their combined effect has not been studied enough. The purpose was to analyze the literature on the assessment of combined SB+PA effect of different intensity on the general and cardiovascular health of a person. When preparing the review, a search was made for publications in the MedLine, Cochrane, Scopus databases, as well as electronic resources e-library, CyberLeninka and libraries of physical culture and sports universities in Russia for 2002-2022.

Issues related to various SB+PA combinations and their effects on general and cardiovascular health are considered and discussed. The facts of the favorable effect of switching sedentary behavior on the same time moderate-intensity PA are presented. The presented data indicate the need for further study, taking into account the mutual substitution of SB and FA of different intensity.

Published: April 2023

Cardiovascular pathology occupies a leading place among all causes of death and permanent disability of the population. In recent years, there has been an increase in the number of cardiovascular comorbidity cases, which leads to a significant deterioration in the quality of life, difficulties in the selection of therapy and a worse prognosis. Cardiorheumatology is an actual and actively discussed direction in this area. One of the most common rheumatic pathologies is osteoarthritis. Researchers identify a number of factors aggravating the course of cardiovascular pathology in the presence of osteoarthritis: regular intake of non-steroidal antiinflammatory drugs, chronic pain syndrome, decreased mobility. The review provides current data on the problem under discussion, in particular, the current understanding of pathogenetic relationships. The issues of safety of non-steroidal anti-inflammatory drugs in cardiovascular patients are highlighted. The potential of using modern immunological cytokines in this group of patients are described using the example of galectin-3 as a marker of prognosis.

Aim. To compare  the epicardial fat thickness  (EFT) in right ventricular anterior wall (RVAW) and left atrial mechanical dispersion  (LAMD) in hypertensive (HTN) patients without arrhythmias and with various types of recurrent atrial fibrillation (AF).

Material and methods. This observational  cross-sectional single-center  study included 383 patients  with HTN, of which 251 did not have AF,  61 patients  had paroxysmal,  and 71 patients  — persistent AF. Echocardiography  performed  against  the  background  of sinus rhythm assessed the EFT in RVAW. In addition, using speckle-tracking echocardiography, the LAMD was determined,  equal to the percentage of the standard  deviation of the time to peak  global longitudinal LA strain in the reservoir phase to duration of cardiac cycle.

Results. In HTN patients without AF, with paroxysmal and persistent AF, the EFT was 6,70 [5,80; 8,00], 8,20 [7,10; 9,93] and 8,70 [7,93; 10,0] mm (р<0,0001), LAMD — 0,72 [0,58; 0,93], 2,87 [2,40; 3,28] and 2,67 [2,11; 3,15]% (p<0,0001), respectively.

Conclusion. In HTN patients with paroxysmal and persistent  AF, the EFT in RVAW and LAMD is significantly greater  than in patients without arrhythmias. In patients with persistent  AF, EFT is greater than in paroxysmal AF, while LAMD practically does not differ.
