Прионовые болезни
Authors: Тихонова, П.А. , Лидохова. О.В
Published: January 2024

Прионовые болезни – это группа генетически и инфекционно обусловленных синдромов, для которых характерен длительный инкубационный период и летальный исход на протяжении 6-24 месяцев после манифестации клинических проявлений. Заболевания являются редкими (1-2 человека на 1 млн/год), однако абсолютно летальными. Прионы обладают устойчивостью к стандартным методам дезинфекции. В настоящее время не разработаны достаточно достоверные методы их прижизненной диагностики и эффективного этиотропного лечения. В статье рассмотрены классификация, основные механизмы этиопатогенеза, клинические проявления, пути передачи заболевания, а также перспективы применения полученных знаний для ранней диагностики болезни Паркинсона и болезни Альцгеймера. Целью исследования является формирование комплексного представления о природе прионовых болезней, а также ознакомление с передовыми разработками в области их диагностики, профилактики и лечения.

Wokół Pietryny. Umysł i zmysły w doświadczaniu krajobrazu miasta
Authors: Szkurłat Elżbieta , Adamczewska Maria
Published: January 2024

Głównym założeniem proponowanej koncepcji zajęć jest doświadczanie krajobrazu miasta poprzez spacer w określonej części Łodzi.
Celem proponowanych zajęć jest tworzenie warunków do łączenia odbioru miejsc z wykorzystaniem zmysłów i zaangażowania umysłowego formie multisensorycznego poznania zorientowanego na odbiór krajobrazu Łodzi i identyfikowanie jego tożsamości. Na doświadczanie krajobrazu miasta składa się głównie obserwowanie, interpretowanie oraz kontemplowanie miejsc. Odbiorowi zmysłowemu towarzyszy również porównywanie, komentowanie, wartościowanie.  Jednym z elementów tej koncepcji zajęć jest uwzględnienie teorii tzw. kalotropizmu, to jest naturalnej skłonności człowieka (wrodzonej potrzeby) do odczuwania, poszukiwania, kontemplowania, podążania ku pięknu i jego tworzeniu. W proponowanym spacerze kalotropizm odnosiłby się zarówno do odbioru i doświadczania krajobrazu postrzeganych miejsc, jak również tworzenia w wyobraźni nowych wizji wybranych miejsc − „ozdabiania tych miejsc wyobraźnią”. Proponowany spacer zawiera niektóre elementy tzw. flanerowania, włóczenia się, specyficznego rodzaju spacerowania po mieście.
W zaplanowanej koncepcji zajęć określone zostały zasady doświadczania krajobrazu miasta w odbiorze zmysłowym, refleksji i interpretacji zawartych m.in. w słowach–kluczach. Zaproponowana została w niej trasa spaceru, treść karty obserwacji do wpisania słów-kluczy odnoszących się do wyników obserwacji. W materiałach pomocniczych do zajęć terenowych zamieszczono najważniejsze informacje i źródła dotyczące miejsc, obiektów na zaproponowanej trasie. Materiały te wspierać mają samodzielną obserwację krajobrazu Łodzi, rozpoznawanie jego genius loci, wsłuchanie się w krajobraz dźwiękowy miasta, identyfikowanie miejsc o znamionach piękna, zrewitalizowanych, ale też miejsc zdegradowanych, nie-miejsc, tzw. miejsc straconych, brzydkich.
Stare Polesie – zmiany krajobrazu miasta
Authors: Dzięcioł-Kurczoba Barbara , Kopeć Witold
Published: January 2024

Praca ma na celu doświadczenie przez uczestnika spaceru (turystę, studenta, ucznia) zmian krajobrazu w północnej części tzw. Starego Polesia w Łodzi, zdecydowanie rzadziej odwiedzanego zarówno przez mieszkańców jak i turystów. Miejsca zostały dobrane w ten sposób, aby ukazać specyfikę tej części miasta oraz tempo i zakres zmian krajobrazu, które tutaj zaszły i nadal zachodzą. W spacer może wprowadzić film Zbigniewa Górniaka „Stare Polesie” przybliżający, zanikający już klimat i krajobraz, niektórych miejsc tej części miasta. Pierwotny wygląd wybranych miejsc na Starym Polesiu uczestnik spaceru może dostrzec w terenie, odczytać z archiwalnych map, rycin i fotografii albo wyobrazić sobie na podstawie załączonych opisów. Wybrane punkty spaceru – miejsca znaczące – nawiązują do różnych okresów rozwoju Łodzi, łącznie z najnowszymi zmianami. Osoba doświadczająca krajobrazu tej części miasta może wykorzystać podczas spaceru większość zmysłów. Doświadczyć ciszy na Cmentarzu Starym, hałasu samochodów jadących po bruku ulicy Legionów czy dźwięków muzyki dobiegających z Akademii Muzycznej i Teatru Arlekin, obok których przebiega wyznaczona trasa. Jedną z propozycji jest wykorzystanie metody refotografii w celu ukazania zmian pojedynczych obiektów lub miejsc. W pracy wykorzystano również mapy historyczne i ortofotomapy z różnych lat, aby uczestnik spaceru sam mógł określić zakres zmian krajobrazu miasta.

Experiments on the Different Numbers of Bidders in Sequential Auctions
Authors: Gunay Hikmet , Huamán-Aguilar Ricardo
Published: January 2024

Consideramos una subasta secuencial de segundo precio con postores globales y locales. Mediante experimentos de laboratorio analizamos el orden de venta correcto de dos bienes cuando el número de postores en cada etapa de la subasta secuencial es diferente. Teóricamente, vender el bien con un gran número de postores al final debería generar un resultado (casi) eficiente, pero venderlo primero debería resultar en un resultado ineficiente con una probabilidad positiva. Nuestros resultados experimentales muestran que vender ese bien al final genera un resultado más eficiente que venderlo primero. Por tanto, los resultados experimentales muestran que, al diseñar una subasta secuencial, es relevante tener en cuenta el orden de venta de los bienes.
Was the post-war international trade order bound to succeed while the Bretton Woods monetary order established in 1944 was doomed to fail?
Authors: De Urioste Ricardo
Published: January 2024

This paper explores the reasons embedded in the original architecture of both the international trade and monetary regimes that determined different outcomes for both. It proposes that the original version of the Bretton Woods monetary regime showed faster its essential failures and basically had to be replaced as early as 1971, while the trade regime embodied in the GATT and later in the WTO managed to at least survive until present day. It posits that correspondence (or the lack of it) of the basic characteristics of the said regimes with the underlying political reality where the regimes would apply (in line with Ruggie´s depiction of «embedded liberalism») accounts for the differentiated outcomes. It explains that the international trade regime showed more flexible traits that allowed it to adjust to the underlying political and led to its survival. The lack of that adaptability element would likewise explain the early demise of the original Bretton woods scheme.
VARIABILITY OF TEMPORAL CHARACTERISTICS OF SNOW COVER IN SIBERIA ON GROUND-BASED DATA
Authors: Martynova Yu. V. , Voropay N. N. , Matyukhina A. A.
Published: January 2024

Estimates of the variability in the dates of the beginning snow cover formation and end of its descent, the establishing and destruction of stable snow cover, the duration these periods, the number of intervals with stable snow cover in the cold season, as well as the duration of the periods of formation and descent of snow cover were obtained in this paper. Differences in the behavior of these characteristics depending on the geographical features of the territory were analyzed. Four groups of stations were considered: low-lying (up to 50 m) stations, high-lying (from 700 m), stations in Western Siberia (60-90ºE) and in Eastern Siberia (90-120ºE). The snow cover ground-based observations data (RIHMI-WDC) for Western and Eastern Siberia over the time period from 1970 to 2019 was used. Along with the general period (1970–2019) the behavior of these characteristics for two subperiods of 1977–2005 and 2006–2019 corresponding to the zonal and meridional circulation epochs was considered. The response of the snow cover to the change in the atmospheric circulation has been obtained. With the prevailing meridional circulation, in comparison with the zonal circulation, the beginning of the snow cover formation occurs later and synchronously at most of the stations of each of the specified geographical groups, and the snow cover descends earlier, but at the same time is much more non-uniform in time (non-simultaneous) within a geographic group. A smaller number of intervals with a stable snow cover in cold season is also shown, which means more stable snow cover during the cold season in meridional circulation epoch then in zonal. An increase in the duration of the snow cover formation and descent time periods was obtained for all the considered geographical groups of stations. The exception is for low-lying station group only. Thus, the conditions of the meridional circulation epoch not only compensate for the changes that occurred in the zonal epoch, but also bring new changes in the temporal characteristics of the Siberian snow cover.

Mindset Changes for Dealing with Complex Climate Impacts - Experiences with a Tool from Courses on Digitalization and Climate-Adapted Urban Development
Authors: Czygan Günter Müller , Wimmer Manuela , Frank Julia , Schmidt Michael , Tarasyuk Viktoriya
Published: January 2024

Economy and society are currently exposed to multi-layered multi-crises. Against the backdrop of the covid pandemic, a growing shortage of skilled workers, increasing armed conflicts or persistent refugee flows, cities and municipalities in particular have to deal with resulting local impacts. Parallel to these highly dynamic crisis events, cities and municipalities continue to be called upon to face the now established challenges of climate change, sustainability and digitalization. More and more, there are organizational and also psychological overloads in coping with everyday tasks as a result of increasing complexities. Because of the excessive demands, there is a retreat to familiar and routine-related everyday work and the neglect of the search for adequate solutions to the increasingly complex problems. Especially in the field of municipal infrastructure, which requires rapid and comprehensive adaptation to the manifold impacts of climate change, this excessive demand increasingly leads to recourse to rather simple solutions, which, however, do not justice to the complexity of the situation. During two certificate courses at Hof University of Applied Sciences (Germany) on the development of climate-adapted urban planning and on successful digitalization in municipal water management, a novel tool for dealing with complex situations was developed to practice on examples. It was observed among the approximately 70 participants in both courses that used this method two to three times already led to a visible change in the perception and assessment of complex situations, without the need for psychologically accompanied training of change behavior.

Risonanze classiche nel racconto della peste del Decameron
Authors: Cavalletti Giuditta
Published: January 2024

In questo testo si propone una lettura della peste raccontata nel Decameron che prenda in esame la presenza di possibili stratificazioni o risonanze di fonti antiche e medievali che si possono intuire nel racconto che Giovanni Boccaccio offre all’inizio della sua opera, quando narra l’origine e conseguenze della peste scatenatasi nel 1348, terribile avvenimento che fa da sfondo e cornice al racconto. Nelle prossime pagine si prenderà in esame sia il debito che Boccaccio ha con la Historia Longobardorum di Paolo Diacono, considerata la fonte principale da cui attinse l’autore fiorentino per dare voce e corpo alla pestilenza fiorentina del XIV secolo, sia alcuni dettagli che sono presenti nel racconto e che sembrano richiamare altre narrazioni.
TRAUMATIC BRAIN INJURY, THE GUT MICROBIOME, AND SOCIOECONOMIC STATUS: A REVIEW
Authors:   Ph.D. Candidate, Department of Counseling Psychology, Graduate School of Education, Fordham University, New York, USA, Spyropoulos Daphne Catherine
Published: January 2024

This article reviews existing literature on three bidirectional relationships. These are traumatic brain injury (TBI) and gut microbiome relationship, the TBI and socioeconomic status (SES) relationship, and the gut microbiome and SES relationship. Literature on the relationship between TBIs and the gut microbiome underscores the loop created through the gut-brain axis, leading TBI to disrupt gut microbiota composition and diversity, which in turn aggravate existing neuroinflammation in the brain. Literature on the relationship between TBIs and SES links lower SES to higher occurrence rates of TBI and poorer recovery outcomes. Literature on the relationship between the gut microbiome and SES, links lower SES to gut dysbiosis, presenting as imbalanced gut microbiota composition and lower diversity. The TBI-gut microbiome, TBI-SES, and gut microbiome-SES bidirectional relationships reinforce health inequity and call for social justice advocacy for the protection of brain health of people of lower socioeconomic backgrounds.

Atherosclerosis is associated with vascular diseases, diabetes, and cancers. The Jumonji C-domain-containing 6 (JMJD6) gene plays an important role in diverse biological processes. In addition, autoantibodies are reportedly useful in the early diagnosis and treatment of many diseases. Here, JMJD6 was identified by serological identification of antigens by recombinant cDNA expression cloning as an antigen recognized by serum IgG from patients with unstable angina pectoris. Then, we performed amplified luminescent proximity homogeneous assay-linked immunosorbent assay using purified recombinant antigens and found elevated levels of serum anti-JMJD6 antibodies (s-JMJD6-Abs) in patients with atherosclerosis-related diseases including ischemic stroke, acute myocardial infarction (AMI), diabetes mellitus (DM), and cancers including esophageal cancer (EC), gastric cancer, lung cancer, and mammary cancer, compared with those in healthy donors. The s-JMJD6-Ab levels were closely associated with hypertension, habitual smoking, and the intima-media thickness, an atherosclerosis index. The better postoperative survival status was shown in patients with EC from the JMJD6-Ab-positive group than the negative group, especially from JMJD6-Ab-positive/PD-L1-negative group and JMJD6-Ab-positive/p53-Ab-negative group than JMJD6-Ab-negative/PD-L1-positive group and JMJD6-Ab-negative/p53-Ab-positive group, respectively. Hence, JMJD6 autoantibodies may reflect atherosclerosis severity, thereby a potential biomarker for atherosclerosis-related diseases including ischemic stroke, AMI, DM, and cancers and for predicting EC prognosis.
Is the Artificial Pollination of Walnut Trees with Drones Able to Minimize the Presence of Xanthomonas arboricola pv. juglandis? Review.
Authors: Manthos Ioannis , Sotiropoulos Thomas , Vagelas Ioannis
Published: January 2024

Walnut (Juglans regia L.) is a monoecious species and although it exhibits self-compatibility, presents incomplete overlap of pollen shed and female receptivity. Thus, cross-pollination is prerequisite for optimal fruit production. Cross-pollination can occur naturally by the wind, the insects, artificially, or by hand. Pollen has been recognized as one possible pathway for Xanthomonas arboricola pv. juglandis infection, a pathogenic bacterium responsible for walnut blight disease. Other than the well-known cultural and chemical control practices, artificial pollination technologies with the use of drones could be a successful tool for walnut blight disease management of orchards. Drones may carry pollen and release it over crops or mimic the action of bees or other pollinators. Although this new pollination technology could be regarded as a promising tool, pollen germination and knowledge of pollen as a possible pathway for the dissemination of bacterial diseases remain crucial information for design and manufacture of aerial pollinator robot for walnut trees. Thus, our purpose was to describe a pollination model with fundamental components, the identification of the “core” pollen microbiota, specify an appropriate flower pollination algorithm, design an autonomous precision pollination robot, and minimize the average errors of flower pollination algorithm parameters through machine learning and meta-heuristic algorithms.
Acoustic-Based Online Monitoring of Cooling Fan Malfunction in Air-Forced Transformers Using Learning Techniques
Authors: Nematirad Reza , BEHRANG MEHDI , pahwa anil
Published: January 2024

Cooling fans are one of the critical components of air-forced (AF) dry-type transformers for regulating internal temperatures. Therefore, effective malfunction detection is crucial to maintain the transformer temperature within an acceptable range and prevent overheating. Regular maintenance occurs periodically and issues with cooling fans may arise between maintenance periods, leading to prolonged operation under malfunctioning conditions and potential failures. In addition, utilities typically have online information about whether a fan works or not without providing information about cooling fan malfunctioning circumstances. To address these challenges, this study proposes learning-based online monitoring techniques to detect malfunctions in AF transformer cooling fans. Random forests (RFs) and convolutional neural networks (CNNs) are developed to classify the audio signals from cooling fans into normal and malfunctioning classes. Unlike RFs, which require separate feature extraction, CNNs are trained based on spectrogram images derived from audio signals. Thus, various time-frequency techniques are utilized for feature extraction in RFs. Besides, multiple data augmentation techniques are employed to enhance the dataset size and diversity. Algorithmic performance is optimized through hyperparameter tuning and classifier threshold adjustment. Simulations reveal that CNNs outperform RFs, whereas the latter provides superior interpretability of acoustic features compared to the former.
Dimensionality Reduction and Research of Hyperspectral Remote Sensing Images Based on Manifold Learning
Authors: Song Wenhui , Zhang Xin , Chen Yijin , Xu Hanghang , Wang Lianchao , Wang Yinggang
Published: January 2024

With the rapid advancements in remote sensing technology, the spectral information from hyperspectral remote sensing images has become increasingly rich, facilitating detailed spectral analysis of the Earth's surface objects. However, this abundance of spectral data poses significant challenges in data processing, such as the curse of dimensionality leading to the “Hughes” phenomenon, "strong correlation" due to high resolution, and "non-linear characteristics" caused by varied surface reflectance rates. Therefore, dimensionality reduction of hyperspectral data has become a crucial task. This paper, grounded in manifold theory and manifold learning techniques, and considering the non-linear structures and features in hyperspectral remote sensing data, elucidates the principles and processes of dimensionality reduction in hyperspectral remote sensing images using manifold learning, with a formalized expression of the process. This article introduces spectral information divergence (SID) into the nearest neighbor graph computation of manifold learning algorithms. The principles and computational processes of nearest neighbor graph algorithms based on Euclidean distance (ED), spectral angle mapping (SAM), and SID are studied, and a comparative analysis of the dimensionality reduction effects under these three metrics in hyperspectral data is conducted. Experiments on feature extraction under different metrics were performed using the publicly available Indian Pines hyperspectral dataset. The intrinsic features obtained post-dimensionality reduction were used as inputs for classification algorithms in ground objects classification experiments, with algorithm runtime, overall accuracy, and Kappa coefficient as evaluation metrics for dimensionality reduction quality. The results demonstrate that nearest neighbor graph computation based on SAM and SID outperforms traditional ED methods; SAM-based computation has the lowest time complexity, while SID-based manifold learning yields the highest accuracy in ground objects classification. Thus, manifold learning based on SAM and SID metrics proves to be an effective method for feature extraction in hyperspectral remote sensing data, underscoring the potential of manifold learning techniques in the dimensionality reduction of hyperspectral remote sensing images.

Authors: Guo Wenxin , Shi Xinyu , Wang Lu , Cong Xin , Cheng Shuiyuan , Li Linling , Cheng Hua
Published: January 2024

Selenium nanoparticles (SeNPs) has higher bioavailability and safety than inorganic selenium, and was widely used in medical, agricultural, nutritional supplements, and antibacterial fields. The present study screened a strain L11 producing SeNPs from a selenium rich dairy cow breeding base in Hubei Province, China. The strain was identified as Bacillus subtilis through physiological, biochemical, and molecular biology analysis. Through optimization of cultivation conditions, the optimal cultivation parameters for L11 to produce SeNPs were pH=6, cultivation temperature of 37 °C, 4 mmol/L Na2SeO3, and cultivation for 48 hours. XPS, SEM-EDS, and TEM were used to verify that the Se particles produced by L11 are SeNPs with diameters ranging from 50 to 200 nm. The combination of protein analysis of different cell components and TEM analysis showed that L11 mainly produces SeNPs through the transformation of the cell's periplasmic space, cell membrane, and cell wall. Adding L11 SeNPs complex to sheep feed can significantly enhance the antioxidant activity and immunity of sheep, and increase the Se content in the neck muscles, liver, and spleen tissues.
Tissue-Based Biomarkers in Aggressive Variant Prostate Cancer: A Narrative Review
Authors: Kouroukli Olga , Bravou Vasiliki , Giannitsas Konstantinos , Tzelepi Vasiliki
Published: January 2024

Prostate cancer (PC) is a common malignancy of elderly men, characterized by great heterogeneity in its clinical course, ranging from an indolent to a highly aggressive disease. The aggressive variant prostate cancer (AVPC) clinically shows an atypical pattern of disease progression, similar to that of small cell PC (SCPC), and also shares the chemo-responsiveness of SCPC. The term AVPC does not describe a specific histologic subtype of PC but rather the group of tumors that, irrespective of morphology, show an aggressive clinical course, dictated by androgen receptor (AR) indifference. AR indifference represents an adaptive response to androgen deprivation therapy (ADT), driven by epithelial plasticity, an inherent ability of tumor cells to adapt to their environment by changing their phenotypic characteristics in a bi-directional way. The molecular profile of AVPC entails combined alterations in tumor suppressor genes retinoblastoma protein 1 (RB1), tumor protein 53 (TP53) and phosphatase and tensin homolog (PTEN). The understanding of the biologic heterogeneity of castration-resistant PC (CRPC) and the need to identify the subset of patients that would potentially benefit from specific therapies necessitate the development of prognostic and predictive biomarkers. This review aims to discuss the possible pathophysiologic mechanisms of AVPC development and the potential use of emerging tissue-based biomarkers in clinical practice.
Gas Temperature Distribution in the Combustion Chamber of a GTM400 Mod Turbojet Engine Powered by Jet A-1 Fuel and Hydrogen
Authors: Brodzik Łukasz
Published: January 2024

Research on engine operation using hydrogen may enable appropriate optimization of thrust and, therefore, performance related to its potential use in aircraft. It is particularly important that the share of hydrogen in combustion affects the reduction of combustion products such as carbon dioxide, carbon monoxide, nitrogen oxide, hydrocarbons and solid matter. This is in line with the new requirements regarding the increased supply of sustainable aviation fuels (SAF) and the related changes in emissions, i.e. reducing the harmful impact of exhaust gases on the environment. The paper presents the results of measurements carried out in the GTM400 MOD turbojet engine. Based on the research performed, the impact of hydrogen and aviation kerosene combustion on selected engine parameters was presented. The paper shows changes in the rotational speed and volume flow of JET A-1 fuel as a function of engine operation time. Changes in temperature measured at the edge of the flame tube were also examined. The tests confirmed that the combustion chamber works correctly in the selected area in the range of tested fuel mixtures. After incorporating hydrogen into the combustion process, the consumption of traditional JET A-1 fuel was significantly reduced.

Published: January 2024

A simple model is developed for membrane fouling, taking into account two main fouling phenomena: cake formation, due to attached solids onto the membrane surface and pores clogging, due to retained compounds inside the pores. The model is coupled with a simple anaerobic digestion model for describing the dynamics of an Anaerobic Membrane BioReactor (AnMBR). In simulations, we investigate its qualitative behavior: it is shown that the model exhibits satisfying properties in terms of flux decrease due to membrane fouling. Comparing simulation and experimental data, the model is shown to predict quite well the dynamics of an AnMBR. The simulated flux best fits the experimental flux with a correlation coefficient r2=0.968 for the calibration data set and r2=0.938 for the validation data set. General discussions are given on possible control strategies to limit fouling and optimize the flux production. We show in simulations that these strategies allow one to increase the mean production flux to 33 L/(h.m2), whereas without control it was 18 L/(h.m2).

An insurance company must be able to manage risks in the form of claims submitted by policyholders. There are several risk measures or actuarial measures that can be used to predict future risks and help companies prepare reserves. These actuarial measures are Value at Risk (VaR), Tail Value at Risk (TVaR), Tail Variance (TV), and Tail Variance Premium (TVP). In this article, we will discuss these actuarial measures for inverse Gaussian distributed claim severity. The Kolmogorov-Smirnov test is used to test the fit of the inverse Gaussian distribution. The maximum likelihood estimator is used as a method to estimate the parameters of the inverse Gaussian distribution. The data used in this article is data on partial loss claims for motor vehicle insurance insurance company PT. ABC in 2019 Category 1 in all regions. However, after testing the goodness of fit of the distribution using the Kolmogorov-Smirnov test for region 3, it did not come from a population with an inverse Gaussian distribution. So the data used to proceed to the actuarial measures estimation stage is only region 1 and region 2. Based on the results of calculating the actuarial measures for inverse Gaussian distributed claim severity, it can be concluded that the value of losses expected by a company can be calculated by taking into account the actuarial measures for claim severity on motor vehicle insurance in Indonesia.

Pyraminx is a twisty puzzle in the shape of a tetrahedron with 4 sides. Pyraminx is played with the bottom completely flat and the front side facing the person holding the Pyraminx. The goal of the Pyraminx game is to randomize the colors, then return the scrambled colors to their original color positions by rotating the sides. This research does not discuss the most effective way of solving Pyraminx but focuses more on proving that movements in Pyraminx form group and that there is a group isomorphism from the group of Pyraminx movements to the  symmetry permutation subgroup in Pyraminx. First, it is proved that movements in Pyraminx form group using 2 methods, namely direct proof in Pyraminx (Pyaminx movement group) and performing permutations in set   containing numeric labels in the form of numbers 1 to 36 on Pyraminx facets by following the movements of Pyraminx ( symmetry permutation subgroup). Furthermore, it is proved that there is a group isomorphism from the Pyraminx movement group to the   symmetry permutation subgroup in Pyraminx.

Abstract. Introduction. Rhino-orbito-cerebral mucormycosis is an angio-invasive infection caused by ﬁlamentous fungi of the Mucoraceae family. Numerous factors were proposed determining mucormycosis against the COVID-19 background. Predisposing factors include uncontrolled diabetes, hematological malignancies, transplantation of solid organs and stem cells, corticosteroids, and weakened immunity. Aim of the study was to investigate the tomographic signs of rhino-cerebral mucormycosis. Materials and Methods. A retrospective study of CT and/or MRI images of 120 patients was conducted, who have been diagnosed with COVID-19 associated with mucormycosis, based on histopathology and/or seeding. Results and Discussion. Imaging ﬁndings of rhino-orbito-cerebral mucormycosis associated with COVID-19 using an adapted simpliﬁed (three-stage) staging system that can be easily applied to everyday practice and helps standardize and improve communication between radiologists and clinicians. The severity of the disease varies from isolated lesions of the paranasal sinuses to extensive brain damage. Clinical outcomes in patients with COVID-19 with rhino-orbito-cerebral mucormycosis gradually increase depending on the severity of imaging. Conclusions. Early diagnosis of mucormycosis is crucial because visualization is essential at staging the disease and assessing the involvement of deeper structures that may be clinically unmanifest. Although both CT and MRI are useful, contrast-enhanced MRI is the method of choice and helps determine the extent of the disease, especially with respect to the deep spread in the maxillofacial region and brain.

Abstract. Introduction. Contrast-induced nephropathy is a serious cause of acute kidney injury and represents an urgent problem in clinical practice. Until recently, there are contradictions in the understanding of many aspects of contrast-induced nephropathy. However, the current situation with using CAs in patients with COVID-19, thus causing contrast-induced nephropathy, has become an urgent issue for clinical physicians and radiologists. Aim of this study is to review some up-to-date information on the use of newer and less nephrotoxic drugs among post-COVID-19 patients with a previous renal impairment. Material and Methods. Topical studies published on studying contrast- induced nephropathies in post-COVID-19 patients have been reviewed herein. Results and Discussion. In case of developing the acute renal failure syndrome caused by using CAs in past-COVID-19 patients, ﬁrst it is necessary to exclude alternative (non-contrast-induced) causes of its occurrence, such as thromboembolism syndrome that may develop upon angiography, ischemic nephropathy, nephrotoxic eﬀects. Upon administration of the X-ray ca, a short-term increase in creatinine levels is possible after 24 hours, but this does not mean the development of contrast-induced nephropathy. Conclusions. To prevent the development of contrast-induced nephropathies, patients must be adequately hydrated. Nephrotoxic drugs should be discontinued at least 24 hours before ca administration. Moreover, the choice of a suitable ca is important.

Abstract. Introduction. Radiation-induced ulcerative proctitis is a serious complication of cancer radiotherapy for prostate, cervix, uterine body, anal canal, and other pelvic tumors. Given the development pattern, there are currently no pathogenetic methods for the treatment of radiation-induced ulcerative proctitis. Aim: To develop a technique for and evaluate its eﬀectiveness in the treatment of patients with radiation-induced rectal ulcers using autologous microfragmented adipose tissue. Materials and Methods. The study included 30 patients, of which 24 (80.0%) were women and 6 (20.0%) were men. Manual lipoaspiration was used to obtain autologous adipose tissue. Then we performed its microfragmentation via transfers. Concentrated autologous adipose tissue was introduced into the edges of the radiation-induced ulcerative defect on the rectal wall under endoscopic control. При контрольной ректоскопии через 6 месяцев у 28 (93,3 %) пациентов была отмечена полная эпителизация постлучевых язвенных дефек- тов прямой кишки. Results and Discussion. The manipulation, from sampling the adipose tissue through the end of injection lasted a little more than an hour (Me = 75.0 min). No intraoperative complications were detected. In one female patient (3.3%), a local recurrence of cervical cancer was found, and therefore that patient was excluded from the study. Control rectoscopy showed the complete epithelialization of post-radiation ulcerative rectal defects in 28 (93.3%) patients after 6 months. Conclusions. The technique proposed to use autologous microfragmented adipose tissue is aﬀordable and eﬀective in the treatment of patients with radiation-induced ulcerative proctitis.

Keandalan merupakan karakteristik utama yang harus dijaga dalam unit pembangkitan listrik seiring dengan kenaikan konsumsi energi listrik di Indonesia. Apabila keandalan tidak dapat dijaga, maka akan dapat merusak peralatan pembangkit dan mengganggu penyaluran pasokan listrik ke beban-beban. Kegagalan pada keandalan unit pembangkitan listrik dapat disebabkan oleh kondisi arus gangguan hubung singkat. Pada penelitian ini dilakukan analisis terkait kondisi arus hubung singkat pada jaringan kelistrikan pada beban motor boiler feed pump (BFP) 4A PT PLN Nusantara Power UP Gresik. Analisis dilakukan untuk menentukan kondisi arus hubung singkat maksimum dan minimum dengan menggunakan perangkat lunak ETAP 12.6. Terdapat dua busbar yang dijadikan objek simulasi ketika mengalami gangguan, yaitu busbar 15 kV dan busbar switchgear M/C 4,16 kV. Hasil simulasi yang didapatkan besar nilai arus hubung singkat maksimum dan minimum. Nilai arus hubung singkat maksimum didapatkan dari kondisi transien berupa gangguan tiga fasa dan satu fasa ke tanah. Sedangkan nilai arus hubung singkat minimum didapatkan dari kondisi steady state berupa arus gangguan antar fasa.
