In response to contemporary challenges and the imperative to adapt medical education to a distance learning format, particularly for international students, there arises a pressing need to develop and implement effective teaching methodologies. This article is aimed at investigating and discussing modern approaches to distance learning tailored for medical students, especially those from abroad. The highlights recent literature sources exploring current teaching methods in distance education for international medical students and outlining the most promising strategies for ensuring high-quality medical education through online platforms. For this analysis, a variety of sources including scientific articles, pedagogical reports, and personal experiences in teaching medical disciplines such as general surgery, nursing practice in surgery, and patient care with a surgical focus in an online format were consulted. It is imperative to underscore that the success of distance education for medical professionals hinges not only on the utilization of technology but also on the cultivation of interactive medical communities. Collaborative problem-solving of clinical tasks and case discussions foster the development of professional identity. The analysis indicates that employing interactive virtual lectures, online simulation workshops, and virtual clinical cases enables medical students to acquire practical skills in real-time. Based on this analysis, it can be inferred that effective distance education for foreign medical practitioners demands a comprehensive approach. Interactive methodologies, teacher support, and the integration of virtual tools facilitate not only the assimilation of theoretical knowledge but also the development of practical skills essential for future medical professionals. The conclusions of this work can be used for the further development of distance medical education, ensuring the high quality of training of specialists in the field of medicine.
EVOLUTION OF LAPAROSCOPIC COMBINED SURGERY IN GYNECOLOGY
Authors: Zezekalo V. M.
Published: March 2024

While laparoscopic combined simultaneous operations have become a valuable method in both surgery and gynecology, further research is necessary to optimize their application. These procedures offer several benefits, e. g. minimizing repeat surgeries, reducing associated surgical and anesthetic complications. This approach can decrease emotional stress and prevent the exacerbation of existing medical conditions in the early and later stages after surgery. Patients often experience better physical activity, mental well-being, and social and sexual functioning.

Looking back, the development of laparoscopy has spanned over centuries. Tracing its roots back to ancient Greece, the late 1800s saw the contributions of pioneering doctors and inventors like Philip Bozzini, Maximilian Nitze, Georg Kelling, Dmytro Ott, Wilhelm Jacobson, Hans Jacobeus, O. Götze, H. Kalk, B. Bosch, Janos Veres, and Kurt Carl Stefan Zemm. Their discoveries and modifications laid the foundation for the laparoscopic procedures used today.

In combined surgeries, two or more coexisting medical conditions are addressed in the same operation. An underlying disease is the one presenting the most significant threat to the patient's health and life regardless of diagnosis, access route, surgical stage, or other factors. In contrast, a secondary, or concomitant, disease poses a lesser threat and might be treatable through a delayed procedure. When planning combined laparoscopic operation, surgeons consider factors like the order of operations, patient positioning, and the specific training and qualifications required.

However, the widespread implementation of simultaneous laparoscopic surgeries in gynecology requires careful consideration. While these procedures offer potential advantages like economic feasibility and minimal post-operative complications, ensuring patient safety remains paramount. Further research and careful selection criteria are necessary to determine the appropriate applications and ensure optimal outcomes.
BRUXISM AS A CAUSE OF NEUROPHYSIOLOGICAL ALTERATIONS IN THE TRIGEMINAL COMPLEX
Authors: Tereshchuk O.H. , Vasylyshyn U.R. , Hatalska Y.O.
Published: March 2024

All components of the dentoalveolar structures demonstrate close interconnections, especially in the intricate relationship between the nervous and muscular aspects of the temporomandibular joint (TMJ). The muscular system relies hierarchically on the regulatory mechanisms of the nervous system. Consequently, any disruption in the interaction between these components can lead to pathology affecting the overall function of the TMJ. One of the most prevalent myogenic disorders is bruxism, impacting 6-20% of the global population. However, pronounced signs of this condition are observed in only 3-5% of individuals. Bruxism is a multifactorial disorder, and its exact etiology remains unclear. Currently, a primary factor in bruxism is considered to be a disturbance in the body's adaptive capacity to cope with stress. Psychological stress induces hyperactivity in the masticatory muscles, leading to intense clenching of the dentition. This, in turn, results in an overload of the supporting tooth tissues, pathological abrasion of the dentition, dysfunction of the temporomandibular joint (TMJ), and the emergence of general clinical symptoms such as headaches, orofacial issues, and neurological symptoms. The pathophysiological foundation of bruxism lies in the excessive strain on the masticatory muscles, causing ischemia and inflammation in the muscle fibers. The inflammatory process in these fibers triggers a persistent excitation of afferent nerve fibers of type C, giving rise to a dull, aching pain. As bruxism is a chronic condition, there is a physiological restructuring of nerve fibers. This involves the initial peripheral and subsequent central sensitization of C-type nerve fibers, resulting in an inappropriate response of the body to physiological stimuli. For instance, the nervous system begins to interpret minor stimuli as painful (hyperalgesia). Currently, no treatment methods completely eliminate bruxism. Modern treatment approaches involve the use of intraoral dental appliances, pharmacotherapy (with muscle relaxants such as botulinum toxin type A and drugs from the benzodiazepine group), and psychotherapy courses aims to teach patients sleep hygiene, self-control, and the elimination of detrimental habits, including clenching the dentition as a response to psychological stress.
COMPARATIVE ANALYSIS OF ABUTMENT TOOTH CONDITION WITH STUMP INLAYS OVER VARIED USAGE PERIODS
Authors: Bilobrov R.V.
Published: March 2024

The aim of this study is to compare the condition of abutment teeth restored with stump inlays over different periods of use by applying periotestometry and radiography findings.

Materials and methods. Ninety-six patients with extensively decayed dental crowns, including low crowns, were examined and treated. The patients were divided into two groups: Group A (main group, standard method for inlays) and Group B (control group, domestic ashless plastic used for modeling). Each group was further divided into three subgroups: A1 and B1 (single-rooted teeth with different crown types), A2 and B2 (collapsible cusp inlays with subsequent artificial crowns), and A3 and B3 (cusp inlays for bridge structures). The stability of the tooth was determined using a Periotest periotestometer (Germany), with scores ranging from -08 to +50 units. Radiological diagnostics and monitoring were conducted using targeted dental radiography with the X-genus DS apparatus. The degree of alveolar bone resorption was quantified using the Fuchs index of alveolar bone destruction.

Result. In group A1, prosthetics with full cast crowns prior to orthopedic treatment initially improved stability by 2.93%, but this effect diminished by 3.39% after 12 months. Both metal-ceramic and all-ceramic crowns led to a decline in stability over the study period. Group B1 exhibited a stability increase of 1.42%, which reduced to 1.14% after 12 months. Metal-ceramic and all-ceramic crowns influenced tooth stability differently throughout the study. Within group B2, prosthetics with full cast crowns initially raised stability by 1.92%, yet this effect decreased to 0.28% after 12 months. Similarly, metal-ceramic and all-ceramic crowns indicated fluctuations in stability of supporting teeth over the study duration. In group A3, prosthetics with full cast bridges prior to orthopedic treatment initially increased stability by 0.86%, declining to a decrease of 2.07% after 12 months. Metal-ceramic bridges exhibited a smaller indicator at 6 months compared to pre-treatment, with this decrease persisting after 12 months. Conversely, all-ceramic bridges demonstrated stability enhancement by 0.61% after 6 months, persisting higher by 1.92% after 12 months. For group B3, prosthetics with full cast bridges prior to orthopedic treatment increased stability by 1.55%, maintaining a higher stability by 1.91% after 12 months. Metal-ceramic bridges indicated a decrease at 6 months compared to pre-treatment, persisting after 12 months. All-ceramic bridges showed a stability decrease by 2.42% after 6 months, yet remaining higher by 1.92% after 12 months compared to pre-treatment levels.

Conclusions. The choice of prosthetic method for the manufacture of pin-and-stem inlays should be justified, taking into account the clinical situation and individual needs of each patient.

In the structure of chronic nosological forms of sialoadenitis, chronic parenchymal mumps accounts for 80%, and is characterized by a recurrent course. To date, the issue of its etiologic origin remains controversial, and data on the pathogenetic influence of external and internal factors on the occurrence of another exacerbation are constantly being supplemented. In particular, the role of the duktogenic pathway of microbial penetration into the glandular duct system is often discussed. Objective: to study the microbiota of parotid secretion in children with exacerbation of chronic parenchymal mumps.

Materials and methods. To investigate the qualitative characteristics and quantitative parameters of microbial flora in the secretion of the parotid salivary glands during disease exacerbation, we enrolled 41 children aged 3 to 15 years, with 18 cases classified as having an active course and 23 as inactive. The study was conducted following the guidelines outlined by CLSI, EUCAST, and relevant State Regulatory Orders and Supplements.

Results. It was found that at the time of the exacerbation in the active course, plasma-coagulating staphylococci and hemolytic streptococci strains in the amount of 106-107 CFU/ml prevailed in the glandular secretion, which were mainly sensitive to beta-lactam antibiotics of all generations, macroliths, natural and semi-synthetic aminoglycosides. An association of microorganisms was isolated from the secretion of 4 glands (11.1%), consisting of coccal cultures, gram-negative bacilli, and yeast cells. In the inactive course, Staphylococcus aureus and hemolytic streptococci slightly prevailed in the glandular secretion, but the proportion of non-pathogenic coccal microorganisms increased, and their number was 105-106 CFU/ml. Their antibiotic patterns did not differ significantly from those in the active course. The isolation of microbial associations concerned 8 glands, which amounted to 17.5%.

Conclusion. Taking into account the presence of microorganisms in the secretion from the parotid glands in the acute exacerbation of chronic parenchymal mumps with pathogenicity factors and an increase in their number depending on the activity of the disease, it is necessary to take a differentiated approach to rational antibiotic therapy by instillation of antimicrobial drugs into the ductal system.
THE EFFECT OF A POLYPROPYLENE IMPLANT TREATED WITH THYROTHRICIN ON THE HYPOGASTRIC TISSUES OF THE ABDOMINAL WALL IN RATS
Authors: Kudriavtsev A.V. , Savosko S.I. , Kryshen V.P. , Nor N.M.
Published: March 2024

Introduction. The study of tissue reactions to the placement of polymeric materials (polypropylene mesh), used for the treatment of hernias, remains relevant. The paper examines the hypothesis regarding the existence of certain differences in tissue reactions to polypropylene implants without and with treatment of the latter with an antimicrobial agent. Objective of this study is to investigate the reaction of the tissues of the peritoneum and the muscle-aponeurotic layer of the abdominal wall to a polypropylene implant treated with thyrothricin, used for the treatment of complicated variants of inguinal hernias.

Materials and methods. Experimental studies were conducted on laboratory sexually mature male Wistar rats. Experimental animals made up 4 groups of 5 animals each. The 1st group included control animals (intact). In the rats of the 2nd group, a defect of the abdominal wall of the hypogastric region was surgically modeled. In the animals of the 3rd experimental group, after modeling the defect of the abdominal wall, a polypropylene mesh implant was placed between the peritoneum and the inner leaf of the aponeurosis of the rectus abdominis muscles. The 4th experimental group consisted of animals in which the polypropylene implant was additionally treated with a thyrothricin solution.

Results. During the experimental study, the integration of tissue elements of the peritoneal walls and the muscle-aponeurotic layer of the abdominal wall with the material of polypropylene meshes was revealed. Active processes of collagenogenesis were observed in the boundary zones and the area of integration with the implant, as well as pronounced manifestations of vascularization of the newly formed connective tissue. The morphological features of the connective tissue formed in the area and around intact implants and meshes treated with thyrothricin did not significantly differ from each other, but significantly prevailed over the condition of the tissues in intact animals. No particular difference between the above-mentioned changes in the tissues of animals of the 3rd and 4th groups was found.

Conclusion. The obtained results indicate positive biocompatibility of body tissues and polypropylene implants. There is no negative effect of polypropylene nets treated with thyrothricin on body tissues and their regenerative potential.
ОСОБЛИВОСТІ СОЦІОКУЛЬТУРНИХ КОМУНІКАТИВНИХ ПРОЦЕСІВ У СУЧАСНОМУ СКРИПКОВОМУ ВИКОНАВСТВІ
Authors: Kiknavelidze Kateryna Olehivna
Published: March 2024

Мета даної статті – освітити яку роль відіграє сучасна скрипкова традиція у світовій музичній культурі і як саме реалізуються її інструменти психологічного впливу на соціум. Методологія дослідження включає методи теоретичного узагальнення і ретроспективного аналізу, що дозволяє теоретично підтвердити важливість висунутих положень. Також використано філософсько-естетичний, історико-культурологічний методи, методи семіотичного та соціологічного аналізу (метод когнітивно-структурної теорії), екзистенціальний та образно-асоціативний підходи. Наукова новизна базується на засадах семіотичного підходу до вивчення скрипкової кавер-культури XXI століття, а це дозволяє розглянути її в контексті художньої культури і в динаміці історичної перспективи. Такий огляд зажадав виходу в сфери мистецтвознавства, культурології, естетики, психології та філософії. Спираючись на досвід у вказаних галузях науки, сучасне скрипкове виконавство досліджено у контексті усіх можливих міждисциплінарних зв'язків. Висновки. Сучасна масова скрипкова культура, крім специфічних музично-мовних елементів, залучає до власних комунікативних інструментів танець, прийоми акторської сценічної майстерності, невербальну комунікацію та певні інші поведінкові типи. З позицій семіотики ці інструменти володіють власними мовами і з їх допомогою відбуваються свого роду соціокультурні комунікативні процеси. Поєднуючи семіотичну теорію Ю. Лотмана із уявленнями про те як семіосфера взаємодіє із феноменом особистості, ми прийшли до визначення психо-семіотичної теорії комунікації. Теоретична модель циклічності поступових процесів уявляється нам як ланцюжок енергетично мотивованих стимулів, що відтворюється в свідомості суб'єкта, а вихідною і кінцевою точкою цього циклу є дія. Власне дану модель комунікативних відносин досліджено з позиції причинно-наслідкових зв'язків щодо двох прямо не пов'язаних просторових дій, в рамках одного культурного поля.
АКТУАЛЬНІ ТЕОРЕТИЧНІ АСПЕКТИ ВИВЧЕННЯ ЕВОЛЮЦІЇ ЄВРОПЕЙСЬКОГО ОПЕРНОГО МИСТЕЦТВА: ІСТОРІЯ ТА СУЧАСНІСТЬ

Мета роботи – розглянути актуальні теоретичні аспекти дослідження генезису та подальшого еволюційного розвитку європейського оперного мистецтва у широкому культурно-історичному контексті. Методологія дослідження визначається поглибленим музикознавчим, музично-аналітичним, виконавським та семіологічним підходами, з виділенням жанрово-стильових та музично-драматургічних параметрів формування оперного жанру. Наукова новизна статті полягає у виявленні музично-історичних, художньо-естетичних, структурно-композиційних та музично-драматургічних основ оперного жанру, які стають показовими та симптоматичними для європейської музичної культури, оскільки дозволяє найбільш повно виражати її характерні риси, сутнісні ознаки та типологічні параметри. Висновки. Оперний жанр постає одним із найскладніших художніх явищ, оскільки, з одного боку, в опері надзвичайно рельєфно виділяється її театральна приналежність з усіма властивими для останньої умовностями, з іншого опера живе переживаннями, відтворює та «проживає» переживання на сцені і робить своїм головним предметом людську здатність до співчуття , як до сприйняття різних психоемоційних станів ц всьому діапазоні почуттів – від трагічного напруження, до радості та катартичного просвітлення. Ще яскравіше, ще більш концентровано зазначені якості оперного жанру проявляються в камерній опері, коли вся увага слухача цілком зосереджена на переживаннях обмеженої кількості персонажів, або зовсім зосереджені на одному герої, як це відбувається в моноопері. Концентрація всього оперного дійства навколо героя, спонукає розглянути загальний погляд на театрального героя, причому театральність стає основою як вивчення його як автономного художньо-естетичного явища, так й визначення шляху самопізнання людини тієї епохи, у яку створено твір. Зазначимо, що в умовах театральної естетики шлях до реальної людини пролягав двома магістральними напрямками. Одне передбачало зниження «високого» героя, інше – піднесення земного. У образі героя дуже сильно виявляє себе життєвий початок, оскільки герой в опері як певний об'єкт, якась особистість, він у своєму оперно-сценічному бутті висловлює «правду життя» і, більше того – вищий задум. Таким чином, здобувши жанрову визначеність, опера одночасно піднялася до рівня естетично та суспільно значущого жанру. Вона стала в один ряд із тими жанрами інших мистецтв, яким до цього належало пріоритетне становище у відображенні людини та її долі.

Published: March 2024

Rice is one of the most widely consumed grain crops (besides wheat and maize) in Iran and various countries. Currently, more and more rice is found to be contaminated with heavy metals, which can have a negative impact on human health. The current study aimed to investigate the impact of coffee bean waste (CBW)  and Rice Husk ( RH)  as bio-adsorbent in reducing Lead, Arsenic, Cadmium, and Nickel in rice (Oryza Sativa). 950 rice samples were collected from various markets in Tehran to extract the heavy metal content in raw, rinsed, soaked with adsorbent, and cooked and drained rice, determined and measured by wet digestion method. Final concentrations of heavy metals in rice samples were analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy according to AOAC International Standards. Batch adsorption experiments were carried out to evaluate the effect of adsorbent dosing, sample state, and ionic strength of solutions on the adsorption of heavy metals onto bio-adsorbents collected simply from legumes and homemade waste at room temperature and then dried at 65 C0 and ground to size mesh 80-100 microns. Arsenic was not found in the samples studied. The cadmium content of the samples was removed through cooking and treated with a mixture of certain percentages of CBW and RH. The content of Lead and Nickel decreased significantly (p<0.05) in all cooking methods. The weekly cadmium intake in bulk and unprocessed packaged rice samples is higher than that of Iranian national standards. Still, with the new eco-friendly detoxification method, there is no risk under any cooking conditions and no food contamination. The current research findings indicate that Food/Agro waste can be utilized profitably in processing rice containing heavy metal ions.

Excessive consumption of paracetamol may lead to hepatic necrosis, nephrotoxicity, extra-hepatic lesions, and even fatality in both humans and animals. The objective of this study was to examine the histological changes in the hepatocytes of yellow rasbora (Rasbora lateristriata) exposed to paracetamol. The fish were subjected to varying concentrations of paracetamol over a period of four days. Group I served as the control group without any paracetamol exposure. Groups II, III, and IV were exposed to 2, 3, and 4 mg/L of paracetamol, respectively. A total of six individuals were allocated to each of the four experimental groups. The histological analysis of the hepatic tissue following paracetamol exposure at concentrations of 2, 3, and 4 mg/L revealed hepatic damage characterized by picnosis, necrosis, and vacuolization. In summary, higher concentrations of paracetamol were associated with an increase in the severity of histopathological changes in the hepatic tissues of yellow rasbora.

İş Sağlığı ve Güvenliği (İSG) önlemleri için yapılması gereken harcamalar işletmeler tarafından göz ardı edilmemelidir. Bu harcamalar, özellikle çok tehlikeli sınıfta yer alan ve iş kazası olabilirlik oranlarına göre tüm sektörler arasında ilk sırada yer alan madencilik sektörü için çok daha hayati öneme sahiptir. Bu çalışmada, öncelikle 2013-2022 yılları arasındaki, beş farklı ekonomik faaliyetten oluşan madencilik sektörüne ait Sosyal Güvenlik Kurumu (SGK) kayıtları incelenmiştir. Doğal taş sektörünün, en fazla çalışan sayısına sahip “diğer madencilik ve taş ocakçılığı” ekonomik faaliyeti içerisinde yer aldığı ve 10 yıllık iş kazası verilerine göre ölüm oranlarında “kömür ve linyit çıkarımından” sonra ikinci sırada yer aldığı tespit edilmiştir. İSG için yapılan harcamaların mali büyüklüğünü ve işletmeye sağladığı faydanın büyüklüğünü analiz etmek amacıyla, bir mermer fabrikasının 2020 yılındaki İSG harcamaları incelenmiştir. Yapılan değerlendirme sonucunda, İSG harcamalarının işletme cirosunun yaklaşık %0,5’ine karşılık geldiği tespit edilmiştir. Ayrıca, Çalışma ve Sosyal Güvenlik Bakanlığı (ÇSGB) tarafından hazırlanan “İş Sağlığı ve Güvenliği Fayda-Maliyet Analizi Proje Raporu” esas alınarak, işletmedeki İSG harcamaları için fayda-maliyet analizi yapılmış ve faydanın İSG maliyetinin 5,54 katı olduğu belirlenmiştir. Diğer madencilik ve taş ocakçılığı ekonomik faaliyetinde alınan İSG önlemlerinin ülke ekonomisine sağlayacağı faydanın ise 2023 yılı fiyatlarıyla ortalama 13 milyar TL olabileceği hesaplanmıştır. Sonuç olarak, İSG için yapılan harcamaların geleceğe yönelik büyük yatırımlar olacağı sayısal olarak ortaya konulmuştur.

Розмір, склад і структура активів підприємства визначають його результативність і ефективність виробництва. Головна мета управління активами фірми полягає в забезпеченні достатнього їх розміру для нормального функціонування підприємства, а також в їх ефективному використанні.

Якщо дебіторська заборгованість, готівка та запаси підтримуються на відносно низькому рівні, існує висока ймовірність банкрутства або нестачі коштів для ведення прибуткової діяльності. В той же час, часто в практиці підприємств виникає проблема зростання рівня дебіторської заборгованості, що нарощує ризики недоотримання засобів.

Дані проблеми, на наш погляд, можуть бути вирішені через посилення контролю показників дебіторської заборгованості та визначенням оптимального її розміру. Аналіз звітності ДП «Новатор» показав суттєве зростання рівня дебіторської заборгованості у 2022 році за продукцію, товари, роботи, послуги, що вимагає посиленої уваги до керування цим видом заборгованості. Так, нами було проведено розрахунок оптимального розміру дебіторської заборгованості, враховуючи рівень можливих витрат, що залежать від дебіторської заборгованості; визначено оптимальний кредитний період для підприємства.

У статті розкрито аспекти актуальності забезпечення ефективного функціонування та довгострокового розвитку підприємств будівельної галузі в умовах війни, кризи та нестабільності. Метою публікації визначено удосконалення системи стратегічного управління розвитком підприємств будівельної галузі в умовах кризи. Розроблено методологію дослідження проблем управління стратегічним розвитком підприємств будівництва, що складається з трьох блоків: 1) визначення викликів та загроз функціонування і розвитку вітчизняних підприємств галузі в умовах нестабільності; 2) аналізування проблематики функціонування і розвитку бізнесу на прикладі одного з будівельних підприємств; 3) визначення напрямів та засобів управління стратегічним розвитком підприємств будівельної галузі в умовах кризи. Доведено, що ключові виклики і загрози  функціонування будівельних підприємств України в умовах кризи формуються за такими складовими їх стабільного функціонування і розвитку, як фінансово-економічна, матеріально-ресурсна, технологічна та кадрова. За результатами аналізування проблематики функціонування і розвитку аналізованого в дослідженні будівельного підприємства встановлено, що найбільш відчутними є такі внутрішні труднощі (проблеми), як низький рівень фінансового стану, зокрема ліквідності і платоспроможності, погіршення техніко-технологічної складової будівельно-технологічних процесів, недостатня адаптивність до вимог та змін державного регулювання. Доведено, що в умовах критично високого рівня нестабільності для забезпечення ефективного управління стратегічним розвитком вітчизняних підприємств будівельної галузі необхідно реалізувати комплекс заходів як з боку безпосередньо підприємств, так і держави.

The West Queen Mother, as a comprehensive cultural phenomenon, has long been the subject of scholarly attention. In recent years, particularly with the rise of traditional Chinese culture, the cultural significance of the West Queen Mother has gained considerable popularity. In the realms of cultural creativity, animation, and gaming, the portrayal of the West Queen Mother has undergone further evolution and innovation, resulting in corresponding shifts in aesthetics. This research investigates the content classification and features of the West Queen Mother's pattern in the Shandong region during the Han Dynasty. By employing a combined approach of pattern analysis and Chinese aesthetics, the aim is to gain a deeper and multifaceted understanding of the culture surrounding the West Queen Mother. This study interprets the aesthetic style and factors associated with the Queen Mother from the perspective of traditional Chinese aesthetics. The conclusion drawn is that the pattern of the West Queen Mother in the Shandong region during the Han Dynasty exhibits aesthetic characteristics ranging from a flat abstraction with simplicity and naturalness to order, normativity, and symbolic representation of divinity. These characteristics demonstrate the richness of Han culture and reflect the Confucian aesthetic concept of the harmony between heaven and humanity, encompassing auspiciousness, loyalty, and filial piety as the highest moral standards, thereby aligning with the prevailing spirit and sociocultural context of the time.

Ion channels are protein structures located in the cell plasma membrane. Sperm cells require calcium ions (Ca2+) to carry out fundamental physiological processes, such as hypermotility, capacitation and acrosomal reaction. Protein extraction is the first, and most critical, stage of molecular tests (Western Blot, proteomic tests, etc). The implementation of these techniques in the study of sperm cells will allow us to understand their physiology (biomarkers) and ways of manipulation (refrigeration, cryopreservation, permeation using streptolysin O (SLO), etc.). The goal of this project was to determine whether if changes in the plasma membrane, brought on by cryopreservation or permeation with SLO, modify the Ca2+ CaV1.2 α1C channel in pig sperm cells. 2 ½ pig ejaculates were taken as working simples, and they were treated as follows: -Control (C): refrigerated semen (SR) 16°/24h; Treatment 1 (T1): SR with SLO T2: cryopreserved semen (SC); T3: SC, previously treated with SLO. It was determined that a better quantitation of proteins from the samples (p<0.001) is obtained with a (total) protein extraction buffer composed of  SDS 2% + β-Mercaptoethanol 3%. The detection of the CaV 1.2 α1C protein was done through Western Bloting, using the Rabbit anti-CaV 1.2 α1C (USA, Sigma-AldrichTM) antigen. Better visibility of the protein band of the Ca2+ channel was achieved in the C and T1 experimental groups; whereas its’ presence was not observed in T2 and T3. It was determined that the Ca2+ CaV 1.2 α1C was present in the sperm cells, and that it deteriorates once the sperm cell is frozen and permeated with SLO, which is linked to the decrease of cell viability percentages. alibri font, size 10, and single line spacing.

The tourism sector is one of the industries that has been hit the hardest by the Covid-19 pandemic crisis. The crisis caused by Covid-19 in the world but also in the countries of the region, has mostly affected the tourism sector, as well as other sectors related to tourism, namely, the hotel industry, crafts and transport but also investments in construction and numerous other projects, both in the public and private sectors. The purpose of this paper is to see the impact of the Covid-19 pandemic on the tourism sector and economic growth. Since tourism was one of the most affected sectors and almost.all tourist centers were closed, the impact on this sector is very large, causing high losses. Meanwhile, the transformative potential and the implications for sustainable policies in the development of the tourism sector have also been presented. For this research, two data sources were used, primary and secondary. Primary data was collected through the questionnaire, which was designed for this purpose. Meanwhile, secondary data have been collected through various reports of credible institutions such as the Kosovo Statistics Agency, scientific articles and other sources that have conducted research relevant to our paper. After collecting the necessary data through concrete analysis, the role and importance of each value was examined. The research with secondary data was carried out during the pandemic period, while 100 respondents participated in the questionnaire. The findings from the analysis of the research show that in 2021 there is a large decrease in tourists in Kosovo from all countries, but that the Republic of Kosovo with the development and application of its policies, especially for the gastronomy sector by easing taxes, offering subsidies for employee salaries, rents, etc. The Republic of Kosovo achieves a recovery of the industry sector, thus significantly increasing the number of tourists throughout the year 2022. Meanwhile, from the results of the research, we saw that the businesses with a tourist character in Kosovo are quite affected by the pandemic, but they hope for help in the form of different from the government to overcome this challenge as easily as possible. The findings from the regression analysis show that in cases where the government has applied measures to limit travel and close borders for tourists, the impact on economic growth has been negative.
Multidimensional valorization of sediments trapped by dams for sustainable and integrated water resources management

Published: March 2024

This article introduces an innovative demarche to sustainable and integrated water resource management by proposing a new strategy for valorizing sediments retained by dams, explicitly focusing on the Moroccan context. The novel demarche presented encompasses five critical dimensions related to sediment valorization: quality, quantity, space, time, and regulation. To achieve this, we have designed an optimal valorization approach complemented by a specific valorization guide tailored to the nuances of Moroccan laws and standards. Our methodology includes a detailed quantitative analysis of retained sediments, a qualitative assessment of their physical and chemical properties, and a spatiotemporal analysis of dam siltation. The optimal valorization approach aims to maximize the use of retained sediments by identifying suitable applications. Simultaneously, the specific guide provides a methodological and regulatory framework aligned with the region's legal requirements. The quantitative analysis evaluates measures taken to quantify sediments retained by dams, while the qualitative analysis assesses their physical and chemical characteristics and suitability for various applications. The spatiotemporal analysis offers a dynamic perspective on dam siltation, emphasizing the most affected areas and the evolution of trends over time. Anchored in the Moroccan context, this research provides crucial insights into the sustainable management of water resources through the integrated valorization of sediments trapped by dams. The presented results have significant implications for watershed management and the optimization of dam operations and reservoirs. Furthermore, they pave the way for similar approaches in regions grappling with reservoir sedimentation issues.
