Authors: Piontek Marlena , Czyżewska Wanda , Mazur-Marzec Hanna
Published: December 2023

A seasonal plethora of cyanobacteria in the plankton community can have severe implications, not only for water ecosystems but also for the availability of treated water. The catchment of the Obrzyca River (a source of drinking water) is seasonally exposed to harmful cyanobacterial bloom. Previous studies (2008–2012; 2019) revealed that the most polluted water of the Obrzyca River was Uście, close to the outlet of Rudno Lake (at the sampling point). Therefore, the effect on this lake was specifically examined in this study. Sampling was performed from May to September at that site and from July to September 2020 at Rudno Lake. The conducted analysis revealed a massive growth of Aphanizomenon gracile, especially in Rudno Lake. The results showed not only the distinct impact of cyanobacterial bloom on phytoplankton biodiversity but also the presence of microcystins and other cyanopeptides in both sampling points. The maximal total concentration of microcystins (dmMC-RR, MC-RR, dmMC-LR, MC-LR, MC-LY, MC-YR) equaled 57.3 μg/L and the presence of cyanopeptides (aeruginosin, anabaenopeptin) was originally determined in Rudno Lake, August 2021. The presence of these toxins was highlighted in our results for the first time. The same samples from the lake were the most toxic in biotoxicological investigations using the planarian Dugesia tigrina. The performed bioassays proved that D. tigrina is a sensitive bioindicator for cyanotoxins. The physical and chemical indicators of water quality, i.e., color, temperature, total suspended solids, and total nitrogen and phosphorus, showed a significant correlation among each other and towards cyanobacterial abundance and microcystin concentrations.

Published: December 2023

Syncytin-1 and -2 are glycoproteins encoded by human endogenous retrovirus (hERV) that, through their fusogenic properties, are needed for the formation of the placental syncytiotrophoblast. Previous studies suggested that these proteins, in addition to the EnvP(b) envelope protein, are also involved in other cell fusion events. Since galectin-1 is a β-galactoside-binding protein associated with cytotrophoblast fusion during placental development, we previously tested its effect on Syncytin-mediated cell fusion and showed that this protein differently modulates the fusogenic potential of Syncytin-1 and -2. Herein, we were interested in comparing the impact of galectin-1 on hERV envelope proteins in different cellular contexts. Using a syncytium assay, we first demonstrated that galectin-1 increased the fusion of Syncytin-2- and EnvP(b)-expressing cells. We then tested the infectivity of Syncytin-1 and -2 vs. VSV-G-pseudotyped viruses toward Cos-7 and various human cell lines. In the presence of galectin-1, infection of Syncytin-2-pseudotyped viruses augmented for all cell lines. In contrast, the impact of galectin-1 on the infectivity of Syncytin-1-pseudotyped viruses varied, being cell- and dose-dependent. In this study, we report the functional associations between three hERV envelope proteins and galectin-1, which should provide information on the fusogenic activity of these proteins in the placenta and other biological and pathological processes.
Changes in the Murine Microbiome and Bacterial Extracellular Vesicle Production in Response to Antibiotic Treatment and Norovirus Infection

Published: December 2023

Norovirus infection is influenced by the presence of commensal bacteria, and both human and murine norovirus (MNV) bind to these bacteria. These virus–bacterial interactions, as well as MNV infection, promote the increased production of bacterial extracellular vesicles (bEVs). However, no correlation has been made between specific bacterial groups, their vesicles, and their impact on norovirus infection. The current study evaluated the impact of select bacterial compositions of murine microbiomes using antibiotic (ABX) cocktails on MNV infection and bEV production. The goal of this research was to determine if increases in bEVs following MNV infection in mice were associated with changes in specific bacterial populations. Bacterial taxa were found to be differentially abundant in both ABX-treated and untreated mice, with the greatest change in bacterial taxa seen in mice treated with a broad-spectrum ABX cocktail. Specifically, Lachnospiraeae were found to be differentially abundant between a variety of treatment factors, including MNV infection. Overall, these results demonstrate that MNV infection can alter the abundance of bacterial taxa within the microbiota, as well as their production of extracellular vesicles, and that the use of selective antibiotic treatments can allow the detection of viral impacts on the microbiome that might otherwise be masked.

Published: December 2023

Parasitoid wasps are fundamental insects for the biological control of agricultural pests. Despite the importance of wasps as natural enemies for more sustainable and healthy agriculture, the factors that could impact their species richness, abundance, and fitness, such as viral diseases, remain almost unexplored. Parasitoid wasps have been studied with regard to the endogenization of viral elements and the transmission of endogenous viral proteins that facilitate parasitism. However, circulating viruses are poorly characterized. Here, RNA viromes of six parasitoid wasp species are studied using public libraries of next-generation sequencing through an integrative bioinformatics pipeline. Our analyses led to the identification of 18 viruses classified into 10 families (Iflaviridae, Endornaviridae, Mitoviridae, Partitiviridae, Virgaviridae, Rhabdoviridae, Chuviridae, Orthomyxoviridae, Xinmoviridae, and Narnaviridae) and into the Bunyavirales order. Of these, 16 elements were described for the first time. We also found a known virus previously identified on a wasp prey which suggests viral transmission between the insects. Altogether, our results highlight the importance of virus surveillance in wasps as its service disruption can affect ecology, agriculture and pest management, impacting the economy and threatening human food security.

Published: December 2023

Salmonid alphavirus strain 3 is responsible for outbreaks of pancreas disease in salmon and rainbow trout in Norway. Although the extensive amount of research on SAV3 focused mainly on the heart and pancreas (of clinical importance), tropism and pathogenesis studies of the virus in other salmon tissues are limited. Here, we used a combination of RT-qPCR (Q_nsp1 gene) and in situ hybridization (RNAscope®) to demonstrate the tropism of SAV3 in situ in tissues of Atlantic salmon, employing a challenge model (by cohabitation). In addition, as previous results suggested that the pseudobranch may harbor the virus, the change in the expression of different immune genes upon SAV3 infection (RT-qPCR) was focused on the pseudobranch in this study. In situ hybridization detected SAV3 in different tissues of Atlantic salmon during the acute phase of the infection, with the heart ventricle showing the most extensive infection. Furthermore, the detection of the virus in different adipose tissues associated with the internal organs of the salmon suggests a specific affinity of SAV3 to adipocyte components. The inconsistent immune response to SAV3 in the pseudobranch after infection did not mitigate the infection in that tissue and is probably responsible for the persistent low infection at 4 weeks post-challenge. The early detection of SAV3 in the pseudobranch after infection, along with the persistent low infection over the experimental infection course, suggests a pivotal role of the pseudobranch in SAV3 pathogenesis in Atlantic salmon.

Natural planned exposure (NPE) remains one of the most common methods in swine herds to boost lactogenic immunity against rotaviruses. However, the efficacy of NPE protocols in generating lactogenic immunity has not been investigated before. A longitudinal study was conducted to investigate the dynamics of genotype-specific antibody responses to different doses (3, 2 and 1) of Rotavirus A (RVA) NPE (genotypes G4, G5, P[7] and P[23]) in gilts and the transfer of lactogenic immunity to their piglets. Group 1 gilts received three doses of NPE at 5, 4 and 3 weeks pre-farrow (WPF), group 2 received two doses at 5 and 3 WPF, group 3 received one dose at 5 WPF, and group 4 received no NPE (control group). VP7 (G4 and G5) and truncated VP4* (P[7] and P[23]) antigens of RVA were expressed in mammalian and bacterial expression systems, respectively, and used to optimize indirect ELISAs to determine antibody levels against RVA in gilts and piglets. In day-0 colostrum samples, group 1 had significantly higher IgG titers compared to the control group for all four antigens, and either significantly or numerically higher IgG titers than groups 2 and 3. Group 1 also had significantly higher colostrum IgA levels than the control group for all antigens (except G4), and either significantly or numerically higher IgA levels compared to groups 2 and 3. In piglet serum, group 1 piglets had higher IgG titers for all four antigens at day 0 than the other groups. Importantly, RVA NPE stimulated antibodies in all groups regardless of the treatment doses and prevented G4, G5, P[7] and P[23] RVA fecal shedding prior to weaning in piglets in the absence of viral challenge. The G11 and P[34] RVA genotypes detected from pre-weaning piglets differed at multiple amino acid positions with parent NPE strains. In conclusion, the results of this study suggest that the group 1 NPE regimen (three doses of NPE) resulted in the highest anti-RVA antibody (IgG and IgA) levels in the colostrum/milk, and the highest IgG levels in piglet serum.
Multi-Dimensional Urban Flooding Impact Assessment Leveraging Social Media Data: A Case Study of the 2020 Guangzhou Rainstorm
Authors: Lu Shuang , Huang Jianyun , Wu Jing
Published: December 2023

In the contexts of global climate change and the urbanization process, urban flooding poses significant challenges worldwide, necessitating effective rapid assessments to understand its impacts on various aspects of urban systems. This can be achieved through the collection and analysis of big data sources such as social media data. However, existing literature remains limited in terms of conducting a comprehensive disaster impact assessment leveraging social media data. This study employs mixed-methods research, a synergy of statistical analysis, machine learning algorithms, and geographical analysis to examine the impacts of urban flooding using the case of the 2020 Guangzhou rainstorm event. The result show that: (1) analyzing social media content enables monitoring of the development of disaster situations, with varied distributions of impact categories observed across different phases of the urban flood event; (2) a lexicon-based approach allows for tracking specific sentiment categories, revealing differential contributions to negative sentiments from various impact topics; (3) location information derived from social media texts can unveil the geographic distribution of impacted areas, and significant correlations are indicated between the waterlogging hotspots and four predisposing factors, namely precipitation, proportion of built-up surfaces, population density, and road density. Consequently, this study suggests that collecting and analyzing social media data is a reliable and feasible way of conducting rapid impact assessment for disasters.

Published: December 2023

A field experiment was conducted on okra (Abelmoschus esculentus L.) for assessing the sustainability of yield with optimum irrigation schedule based on soil moisture depletion. Four irrigation treatments: Irrigation at I1:20%, I2:30%, I3:40% and I4:50% of soil moisture depletion rate in main plots and three fertilizer treatments: Fertigation at F1:100%, F2:80% and F3:60% of recommended NPK (100:25:40 kg/ha) in subplots were tested. Soil matric potential was recorded continuously using electronic tensiometers. The soil moisture characteristics curve was derived for various soil matric potential value sand the soil water content. The irrigation controller triggered solenoid valves for irrigation when soil moisture depletion reached a prespecified level in each treatment. Soil moisture depletion values were significantly predicted based on a regression model calibrated for each treatment over the crop growing period. The model gave minimum prediction error (PE) for I1, followed by I2, I3 and I4, respectively. Plant growth and yield parameters were significantly influenced by the soil moisture availability under each treatment. It is recommended that irrigation be scheduled at 20% soil moisture depletion rate together with 100% NPK fertilizer application for attaining sustainable yield of okra (12.3 t/ha), apart from maximum WUE (3.5 kg/m3) and plant growth parameters under semiarid inceptisols.

Published: December 2023

This comprehensive review explores aquaponics as an environmentally friendly solution aligned with SDGs and food sovereignty, assessing various aspects from system design to automation, and weighing social, economic, and environmental benefits through literature and case studies. However, challenges persist in obtaining organic certification and legislative recognition, hindering its growth. Achieving remarkable water use efficiency, up to 90%, relies on adaptable fish species like Nile tilapia and carp. Nutrient-rich fish feeds notably benefit low-nutrient-demanding greens. Ensuring water quality and efficient nitrification are pivotal, supported by IoT systems. Despite its efficiency, integrating Industry 4.0 involves complexity and cost barriers, necessitating ongoing innovation. Economies of scale and supportive horticultural policies can bolster its viability. Aquaponics, known for its efficiency in enhancing crop yields while minimizing water use and waste, is expanding globally, especially in water-scarce regions. Aquaponics, pioneered by the University of the Virgin Islands, is expanding in Europe, notably in Spain, Denmark, Italy, and Germany. Asia and Africa also recognize its potential for sustainable food production, especially in water-limited areas. While it offers fresh produce and cost savings, challenges arise in scaling up, managing water quality, and meeting energy demands, particularly for indoor systems. Egypt’s interest in desert and coastal regions highlights aquaponics’ eco-friendly food production potential. Despite the associated high costs, there is a quest for practical and affordable designs for everyday integration. Research in arid regions and industry advancements are crucial for aquaponics’ global food production potential. Deeper exploration of intelligent systems and automation, particularly in large-scale setups, is essential, highlighting the industry’s promise. Practical application, driven by ongoing research and local adaptations, is a key to fully harnessing aquaponics for sustainable food production worldwide.

Published: December 2023

The absence of a basin-wide apportionment agreement on using the Nile River equitably has been a long-standing source of disagreement among Nile riparian states. This study introduces a new approach that the riparian states can consider that quantifies the Nile River’s apportionment. The approach includes (1) developing a basin-wide database of indicators representative of the United Nations Watercourse Convention (UNWC) relevant factors and circumstances, (2) developing an ensemble of indicator weighting scenarios using various weighting methods, and (3) developing six water-sharing methods to obtain a range of apportionments for Egypt, Sudan, Ethiopia and the group of the White Nile Equatorial States for each weighting scenarios. The results illustrate a relatively narrow range of country-level water apportionments, even though some individual factor weights vary from 3% to 26%. Considering the entire Nile River, the water apportionment for Ethiopia ranges from 32% to 38%, Sudan and South Sudan from 25% to 33%, Egypt from 26% to 35%, and the Equatorial States from 5% to 7%. We trust that the six proposed equitable water-sharing methods may aid in fostering basin-wide negotiations toward a mutual agreement and address the dispute over water sharing.

Arsenic (III) exposure, often from contaminated water, can have severe health repercussions. Chronic exposure to this toxic compound is linked to increased risks of various health issues. Various technologies exist for arsenic (III) removal from contaminated water sources. This work synthesized ZnO-CuO nanocomposites through ultrasound-assisted coprecipitation, generating abundant hydroxylated sites via the deposition of ZnO nanoparticles onto CuO sheets for enhanced arsenic (III) adsorption. Structural characterization verified the formation of phase-pure heterostructures with emergent properties. Batch studies demonstrated exceptional 85.63% As(III) removal at pH 5, where binding with prevalent neutral H3AsO3 occurred through inner-sphere complexation with protonated groups. However, competing anions decreased removal through site blocking. Favorable pseudo-second order chemisorption kinetics and the 64.77 mg/g maximum Langmuir capacity revealed rapid multilayer uptake, enabled by intrinsic synergies upon nanoscale mixing of Zn/Cu oxides. The straightforward, energy-efficient ultrasonic production route makes this material promising for real-world water treatment integration.

Published: December 2023

In this paper, we proffer a novel technique designed for low-cost and computationally light localization of mobile nodes in an urban terrain, by leveraging the extended COST 231 Hata Path-Loss (PL) model and the Trilateration technique. Our approach accounts for the possibility of a Non-Line-of-Sight (NLoS) scenario in a medium-sized city, wherein one of the three reference nodes required for the trilateration approach encounters NLoS impediments. Our proposed method proceeds with localization by utilizing solely two Line-of-Sight (LoS) reference nodes, while integrating the localization system simulator with an Extended Kalman Filter (EKF). The simulation results presented herein demonstrate a marked enhancement in performance, surpassing that of trilateration in scenarios where three LoS nodes cannot be established.
Absolving Conflict Through Principles of Servant-Leadership
Authors: Stoddard Brandon
Published: December 2023

This article explores the inevitable and unchecked conflicts that arise between people and how it can turn into unmanageable rage and harmed relationships. Both instigators and recipients of conflict are ultimately wounded by its accompanying outcomes. By sharing several examples from my life, including the threat of harm from a deadly weapon towards my three-year-old son by his uncle, I demonstrate the hurt caused by conflict and how principles of servant-leaders can help individuals restore positive associations. When faith is stronger than the bitterness and hostility that often plagues humanity, love offers a longer-term perspective thereby opening a way towards forgiveness. The foundation of healthy relationships and a strong community is established by serving one another rather than focusing on one’s own self-interests. By implementing ten characteristics of servant-leadership including awareness, listening, empathy, and healing, I contend that people can transcend conflict and overcome relational obstacles. This in turn allows people to exhibit a greater capacity for love and forgiveness for the optimal well-being of one another and society at large.

Highly Strong, Tough, and Cryogenically Adaptive Hydrogel Ionic Conductors via Coordination Interactions
Authors: Wang Zhuomin , Wang Siheng , Zhang Lei , Liu He , Xu Xu
Published: December 2023

Despite the promise of high flexibility and conformability of hydrogel ionic conductors, existing polymeric conductive hydrogels have long suffered from compromises in mechanical, electrical, and cryoadaptive properties due to monotonous functional improvement strategies, leading to lingering challenges. Here, we propose an all-in-one strategy for the preparation of poly(acrylic acid)/cellulose (PAA/Cel) hydrogel ionic conductors in a facile yet effective manner combining acrylic acid and salt-dissolved cellulose, in which abundant zinc ions simultaneously form strong coordination interactions with the two polymers, while free solute salts contribute to ionic conductivity and bind water molecules to prevent freezing. Therefore, the developed PAA/Cel hydrogel simultaneously achieved excellent mechanical, conductive, and cryogenically adaptive properties, with performances of 42.5 MPa for compressive strength, 1.6 MPa for tensile strength, 896.9% for stretchability, 9.2 MJ m
−3
for toughness, 59.5 kJ m
−2
for fracture energy, and 13.9 and 6.2 mS cm
−1
for ionic conductivity at 25 and −70 °C, respectively. Enabled by these features, the resultant hydrogel ionic conductor is further demonstrated to be assembled as a self-powered electronic skin (e-skin) with high signal-to-noise ratio for use in monitoring movement and physiological signals regardless of cold temperatures, with hinting that could go beyond high-performance hydrogel ionic conductors.
Perturbations on Oxybiotin Leading to Biotin. A DFT Treatment
Authors: Türker Lemi
Published: December 2023

In the present computational study, conversion of oxybiotin to biotin by means of oxygen to sulfur replacement has been investigated within the restrictions of density functional theory at the level of B3LYP/6-31++G(d,p). Both of the molecules have not only exothermic heat of formations but also favorable Gibbs free energy of formation values at the standard state. They are electronically stable. Various quantum chemical data accompanying the perturbation considered have been collected and discussed including UV-VIS spectra. The oxygen to sulfur replacement highly affects not only the distribution of molecular orbital energy levels but also the energies of the molecular orbitals in such a way that going from oxybiotin to biotin the HOMO energy level raises up but the LUMO decreases. The both occur at unequal extents thus biotin exhibits some bathochromic effect compared to oxybiotin.

Introduction: This study aimed to derive and assess the performance of a multi-biomarker model from a combination of basic laboratory biomarkers in predicting mortality of hospitalized COVID-19 patients.
Methods: This was a cross-sectional study conducted in a university-affiliated hospital in Malaysia. Data of confirmed COVID-19 patients who were admitted from January 2020 to August 2021 were retrieved including their admission C-reactive protein (CRP), lactate dehydrogenase (LDH), and neutrophil-lymphocyte ratio (NLR). Patients were classified as non-survivors or survivors according to their hospital mortality status. Multi-variable logistic regression analysis was used to derive the multi-biomarker model.
Results: A total of 188 confirmed COVID-19 patients were analysed, of which 46 (23%) died in the hospital. Their mean age was 52 (SD 17) years, 104 (52%) were males, 114 (57%) had severe COVID-19 pneumonia, with mean APACHE II score of 14 (SD 10). On admission, those who died had higher median levels of CRP 96.0 (IQR 39.8–182.0) vs 23.0 (IQR 0–67.0 mg/L, p < 0.001), of LDH 973.0 (IQR 706.5–1520.0) vs 515.1 (408.8–738.8 IU/L, p < 0.001), and of NLR 10.1 (IQR 5.5–23.6) vs 2.8 (IQR 1.5–5.9, p < 0.001). The multi-biomarker model had a higher area under the curve (0.866, 95% CI 807-0.925) compared to its constituent individual biomarkers. At its optimal cutoff, this model had 78.9% sensitivity and 76.5% specificity for mortality prediction.
Conclusion: A multi-biomarker model of CRP, LDH, and NLR predicted in-hospital mortality with a very good performance in our hospitalised COVID-19 patients.
РАННЄ ОРТОДОНТИЧНЕ ЛІКУВАННЯ ДІТЕЙ З ВРОДЖЕНИМИ НЕЗРОЩЕННЯМИ ГУБИ ТА ПІДНЕБІННЯ

Published: December 2023

Поширеність зубощелепних аномалії або деформації у дітей з вродженими однобічними та двобічними незрощеннями губи та піднебіння сягає близько 94%. Мета дослідження. Провести аналіз спеціалізованої наукової літератури для узагальнення даних про раннє ортодонтичне лікування дітей з вродженими однобічними незрощеннями губи та піднебіння. Матеріали і методи дослідження. У статті проаналізовано і вивчено сучасну наукову вітчизняну та зарубіжну літературу за останні роки (PubMed), що висвітлює питання ортодонтичного супроводу зазначеної категорії дітей. Результати та їх обговорення. Реабілітація дітей з незрощеннями на різних етапах росту та розвитку вимагає участі мультидисциплінарної команди фахівців різного профілю. Шляхи оптимального лікування дітей з однобічними та двобічними незрощеннями встановити надзвичайно важко. При виявленні незрощень, майбутні батьки потребують негайної консультації спеціалістів, включаючи ортодонта, щодо можливості реабілітації дитини після народження та психологічної підтримки. Для росту та розвитку дитини важливим аспектом є вирішення питання ефективного вигодовування. Передхірургічна ортодонтична підготовка у сучасному розумінні цього поняття бере початок з середини минулого століття. Раннє ортодонтичне лікування дітей з вродженими однобічними та двобічними незрощеннями губи та піднебіння має попередити важкі деформації зубо-щелепного апарату. Метою є створення передумов для правильного росту і формування верхньої щелепи. Найважливіше завдання – нормалізація порушених функцій. Незважаючи на дії мультидисциплінарної команди, у більшості пацієнтів з незрощеннями у період змінного прикусу спостерігається звуження та вкорочення верхньої щелепи. Для усунення деформацій прикусів, отримання задовільного overjet (сагітального перекриття), overbite (вертикального перекриття) та нормалізації трансверзальних розмірів верхньої зубоальвеолярної дуги у більшості випадків проводиться розширення верхньої щелепи (зубної дуги). Висновки. Висока поширеність зубощелепних аномалій та деформацій у дітей з вродженими однобічними та двобічними незрощеннями губи та піднебіння, одночасне поєднання багатьох факторів ризику стоматологічних та загальних захворювань, що впливають на ортодонтичне лікування, зумовлює необхідність розробки та удосконалення існуючих комплексів міждисциплінарного підходу до лікувально-профілактичної допомоги на всіх етапах реабілітації. За відсутності адекватного ортодонтичного супроводу розвиваються стійкі форми зубощелепних деформацій.

Amaç: Bu prospektif çalışmanın amacı infertil erkek hastalarda shear wave elastografinin (SWE) sperm sayısı ile ilişkisini saptamak ve tanısal performansının değerlendirilmesidir.
Materyal ve Metod: Çalışma infertilite tanısı almış ve semen analizi yapılmış 113 hasta ile yapılmıştır. Tüm hastalara US incelemesi ve virtual touch tissue imaging quantification (VTIQ) kullanılarak SWE incelemesi yapıldı. Her testiste toplam 6 ölçüm yapıldı.US inceleme ile testislerin hacim ölçümleri yapıldı.
Bulgular: Azospermi hastalarında sağ ve sol testis volüm değerleri diğer gruplardan istatistiksel olarak farklı ve düşük değerde bulunmuştur(p=0,001). Azospermi hastalarında tüm zonlarda ve ortalama SWE değerleri diğer gruplara göre anlamlı yüksek bulunmuştur(p=0,001). Sperm sayısı ile ortalama volüm arasında pozitif yönde orta şiddette bir ilişki saptanmıştır (r=0,545, p=0,001). Sperm sayısı ile ortalama SWE arasında negatif yönde orta şiddette bir ilişki saptanmıştır (r=-0,429, p=0,001). Ortalama volüm ile ortalama SWE arasında negatif yönde orta şiddette bir ilişki saptanmıştır (r=-0,590, p=0,001). Sperm sayısı normal hasta grubu ile azospermi hastaları arasında yapılan ROC analizinde kesim değeri 2,06 m/sn olup sensivite (duyarlılık) %72 spesivite(özgüllük) %87,88 ölçülmüştür. (p<0,001; EAA=0,837; Sensitivite= 72,00% (95% GA 46,5-85,1); Spesivite=87,88% (95% GA 81,5-95,2). Azospermi hasta grubu ile oligospermi hasta grubu arasında yapılan ROC analizinde kesim noktası 2,04 m/sn olarak belirlenmiştir. Buna göre yapılan değerlendirmede sensivite %72 spesivite %83,33 ölçülmüştür. (p<0,001; EAA=0,789; Sensitivite= 72,00% (95% GA 46,5-85,1); Spesivite=83,33% (95% GA 81,5-95).
Sonuç: İnfertilite şikayetiyle başvuran erkek hastalarda testis parankiminin değerlendirilmesinde, SWE invaziv olmayan bir yöntem olup gri skala ve RDUS tetkiklerine ek yararlı bilgiler sağlayabilir.

Seismic activations in Turkey in the 17th – early 21st centuries and Kahramanmarash earthquakes on February 6, 2023

The long-term seismic regime of Turkey for the 17th - early 21st centuries are analyzed. It is shown that the fundamental feature of the seismic regime is periodic seismic activations (SA) of strong earthquakes. During the analyzed period, 14 seismic activations of various durations (from 4 to 24 years) and a different number of events (from 4 to 22) were traced. The last SA in Turkey began in 2011, and most likely did not end with the Kahramanmarash earthquake in 2023. SA, as a rule, involves the main seismically active regions of the country (the Aegean coast, the North and East Anatolian faults), but with a clear dominance a certain seismically active area with reduced activity of others. An analysis of historical seismicity shows that strong earthquakes along the North and East Anatolian faults in many cases occur in the same source zones, confirming the concept of seismic sources as inherited geological structures, which may serve as an important prognostic symptom. The Kahramanmaraş earthquakes on February 6, 2023 occurred in the framework of the seismic activation that began in 2011.The position of the Mahmaranmarash seismic source on the southern segment of the East Anatolian fault is in good agreement with displacement of seismic sources from north to south along this fault in the 20th century.

Статья посвящена развитию русского дипломатического присутствия и созданию русской военной разведки в Константинополе в рамках российско-османских дипломатических отношений от подписания Константинопольского мирного договора 1700 г., по которому Россия впервые получала право иметь постоянного дипломатического представителя в османской столице, до заключения Константинопольского мирного договора 1720 г., по которому Россия вернула себе это право и начала укреплять свои политические позиции на международной арене.

The paper is devoted to the development of Russian diplomatic presence and the establishment of Russian military intelligence in Constantinople within Russian diplomatic relations with the Ottoman Empire from the signing of the Peace Treaty of Constantinople of 1700, when Russia obtained the right to have a permanent diplomatic representative in the Ottoman capital, to the signing of the Peace Treaty of Constantinople of 1720, when Russia returned this right and began to strengthen its political positions in the international relations.
A spin doctor unwilled: archim. John (Wendland) in the election of the Antiochian patriarch Theodosius VI (Abou Rjaileh) (1958-1970)
Authors: Копоть Е.М.
Published: December 2023

В статье анализируется история взаимоотношений Русской и Антиохийской Православных Церквей в ХХ веке. На основании впервые вводимых в научный оборот документов Государственного архива Российской Федерации, которые ранее были засекречены, раскрывается ключевой сюжет миссии первого представителя Московского патриархата при Антиохийском патриархе архим. Иоанна (Ведланда). Избрание в 1958 г. патриарха Феодосия VI (Абурджели) стало поворотным моментом в истории двусторонних отношений Русской православной церкви и Антиохийского патриархата. Выступая инструментом советской внешнеполитической деятельности, архим. Иоанн (Вендланд) возглавил избирательную кампанию просоветского кандидата митрополита Александра (Жихи). В условиях политического соперничества СССР и США на Ближнем Востоке миссия архим. Иоанна потерпела поражение, что стало следствием недостатков внешнеполитической деятельности Московского патриархата в предшествующее десятилетие.

The article analyses the history of relations between Russian and Antioch Orthodox Churches in the 20th century. The mission key plot of the first Moscow Patriarchate representative to the Patriarch of Antioch Archimandrite John (Wendland) is revealed based on documents from the State Archive of the Russian Federation, which were previously classified, being introduced into scientific circulation for the first time. The election of Patriarch Theodosius VI (Abou Rjaileh) in 1958 was a turning point in the history of bilateral relations between the Russian Orthodox Church and the Patriarchate of Antioch. Acting as a Soviet foreign policy instrument, archimandrite John (Wendland) headed the election campaign of the pro-Soviet candidate, Metropolitan Alexander (Zhikha). In the context of political rivalry between the USSR and the USA in the Middle East, the mission of Archimandrite John was defeated, which was a consequence of the shortcomings in the foreign policy activities of the Moscow Patriarchate in the previous decade.
