Mechanisms of Pol II Recruitment to the Human Beta-Globin Locus Control Region Super-Enhancer
Authors: Johnson Breanna , Gibbons Matthew , Bushra Fabia , Fang Yu , Bungert Jorg
Published: October 2023

The human ꞵ-globin gene locus consists of five genes that encode subunits of hemoglobin. The locus control region (LCR) regulates these genes, acting as a super-enhancer to promote high-level of β-globin expression in erythroid cells. The LCR, like other super-enhancers, is known to recruit transcription complexes and generate non-coding enhancer RNA (eRNA). Past research has suggested that super-enhancers form phase-separated transcription initiation domains that concentrate RNA polymerase II (Pol II) and transfer Pol II to target gene promoters during transient looping interactions. The aim of this project is to examine the role of TFIIH, involved transcription initiation, in enhancer RNA production and Pol II transfer in the globin gene locus. The LCR was immobilized on magnetic beads and incubated with erythroid nuclear protein extracts. Proteins not bound were washed away and bound proteins were subjected to western blotting experiments. The data show that TFIIH is bound at the LCR and thus may be involved in eRNA production. Cut & Run experiments were performed to examine the localization of TFIIH in the globin gene locus in intact cells. In the future, the laboratory plans to deplete TFIIH and examine production of eRNA and Pol II recruitment at the LCR.
The Effacement of Women in the French Resistance
Authors: Etienne Stella
Published: October 2023

Women who participated in the French Resistance effort have been thought to self-efface themselves from history. This paper aims to show that though it might be possible to come to this conclusion if the words they say are taken at face value, women in the French Resistance often represented their contributions in similar ways notably through the medium of memoirs that focus on duty, banalities of life, and a refusal to succumb to negative attitudes or victimization despite the horrors of the 1940’s. By comparing three notable female resistance figures (Lucie Aubrac, Germaine Tillion, and Agnés Humbert) in conjunction with numerous interviews of other women, it is evident that these women do not seek to efface themselves or other women’s contribution. Instead, the common bias of looking at Resistance efforts through a masculine heroism lens marginalizes these women’s contributions. By removing this lens or rethinking what female heroism means reconciles these women’s efforts to their true place in the historical record. The fact that these women deny their heroism does not downplay their contribution to the resistance effort, especially after constantly affirming the importance of these efforts.

Published: October 2023

In the construction industry, workers are constantly exposed to different environmental and other hazards that pose risks to their health. Bluetooth-connected devices host the potential to reduce health risks to workers by tracking heart rate (HR), particularly upon implementation into an Internet of Things (IoT) framework. An Internet of Things (IoT) system is one in which multiple devices are connected to transmit information to each other in real-time. A literature and industry review has been conducted to determine which devices would be most applicable to monitor HR in an IoT system to accurately portray real-time worker conditions. Experimentally, the most applicable devices found were then put under field tests imitating traditional work conditions through the performance of specific activities. The performance and accuracy of the devices under these conditions were then evaluated from the data collected. The study has been designed to determine whether chest, finger, and wrist devices could be used to actively track HR.  The devices used included the Viatom Wellue O2Ring finger monitor, Polar Ignite GPS Fitness Watch wrist monitor, and the Polar H10 chest monitor, serving as test cases to see if and by how much the location of the device on the body differed with the HR found. All three devices could connect to the IoT system and transmit data within a specific timeframe correctly. Covariance and standard deviations measured by the Viatom Wellue O2Ring finger monitor and the Polar Ignite GPS Fitness Watch trials among participants were above the normal thresholds, indicating non-negligible differences around the mean and showing disparities in the accuracy of these devices. Furthermore, the results were found to be too inaccurate for widespread commercial deployment for tracking mid to high HR levels while performing construction-related labor. Overall, the use of Bluetooth-connected devices to track workers’ HR and other vitals has the potential applicability to improve safety in hazardous environments. However, future technological development must occur before implementing predictive safety systems into real-time monitoring to effectively monitor laborers performing strenuous tasks in harsh environments.
Reducing Cement Plant Emissions via Algae Cultivation and Anaerobic Digestion
Authors: Muchnok Hailey , Wilkie Ann C.
Published: October 2023

Concrete is an essential aspect of modern infrastructure, and is a much-preferred construction material as it is a highly resistant and requires low maintenance. Concrete is produced through the creation of a paste comprised of cement and water that is mixed with aggregates such as sand and gravel. However, the concrete industry is one of the largest consumers of natural resources globally, and the emissions associated with its production are very high. Cement, one of the primary constituents of concrete, emits 0.93 pounds of CO2 for every pound produced. Thus, concrete production is a major source of CO2 emissions and accounts for approximately 8% of global carbon emissions. As the global demand for concrete continues to increase, it is evident that efforts must be made to reduce emissions associated with its production to mitigate climate change. This research proposes that the cultivation of algae can be integrated into the process of cement production so as to reduce the emissions associated with concrete. Algae uptake CO2 through photosynthesis, having a CO2 bio-fixation efficiency of 10-50 times higher than terrestrial plants. Algae have the ability to capture 1.8 kg of CO2 per kilogram of algal biomass. Therefore, we hypothesize that, through the integration of algae cultivation and cement production, CO2 can be effectively recycled through a closed-loop system. Algal biomass can be cultivated using the CO2 emitted from cement flue gas. The cultivated algae can be harvested and used to produce methane gas (CH4) via anaerobic digestion, which can in turn be used to power the cement plant, which will in turn produce more CO2 to be captured through further algal cultivation.
Intelligent encryption with improved zealous method to enhance the anonymization of public health records in cloud

Published: October 2023

In order to keep the cost of installing advanced encryption scheme (AES) hardware to a minimum and to hide the protected key from hackers, existing networks’ tactics are employed in this study. This is the biggest drawback of the present methods since there is no security while keeping the concealed key of the AES encryption method. The user is unable to remember all the AES keys since it is necessary to connect with several people using various AES keys. The suggested approach successfully counters both facet and brute force assaults. The advanced encryption method is the safest algorithm to utilize for trustworthy encryption, according to the findings. But the issue is that the advanced encryption scheme makes brute force attack less effective. Honey encryption is thus used. The recommended method encrypts the dataset after dataset anonymization to ensure privacy. An enhanced zealous technique is used to do anonymization when a middle dataset is created using the supplied key. After the dataset has been sorted, the dataset with the higher rank is the one that gets encrypted first. The user receives these datasets together with a decryption key for the encrypted records, enabling them to swiftly obtain the data they need.

Published: October 2023

This paper presents a case study about the challenges and good building practices involved in the execution of structural reinforced concrete pile caps over steel piles. The structural reinforcements were carried out in a project with 3 residential towers of approximately 30 floors each, located on the seafront. As a result, it was observed that mix design to define the type and characteristics of concrete, prototype event, particularities of the construction site, executive procedures employed, as well as the systematic monitoring and control of concreting events and other constructive stages were determining factors to promote the safety and quality of reinforcement services in accordance with the assumptions and design requirements.
Evaluation of "GIS" related tools and their applications in the rivers hydraulic modeling
Authors: Rodríguez1 Daniel , Torrealba2 Wilis , Rincón3 Jean Carlos
Published: October 2023

The research work presented was carried out with the purpose of evaluating GIS Water and HECgeoRAS Geographic Information System (GIS) related tools, which function as a connection node between the HEC-RAS model and the QGIS and ArcGIS software respectively. Here the conditions of creation of the digital model of the land are leveled, with the purpose of obtaining a final result from a parity of circumstances. The case study chosen to obtain the results was the Quebrada Borure located in the city of Barquisimeto, State of Lara, Venezuela. Once both solutions provided by the HEC-RAS hydraulic modeler were obtained, the correlation between both products was determined, being high, close to the value of the unit. Therefore, it could be concluded that both tools are applicable in the data processing for the HEC-RAS model, with the advantage that GISWater is a free license and works under the geographic information system QGIS with the same characteristics.

Effects associated by the change of cauce río San Lorenzo, Carmen de Viboral Antioquia
Authors: Cardona Jorge Wilson Naranjo , Moreno Yimmy  Montoya
Published: October 2023

The research object of this project revolves around the changes in the riverbed during river diversion. For this purpose, sampling work was conducted in the San Lorenzo River basin of El Carmen de Viboral city in eastern Antioquia, taking into account physical and chemical variables and biological indicators such as benthic macroinvertebrates. It has been confirmed that the diversion and/or changes in the San Lorenzo riverbed have led to changes in its physical, chemical, and biological characteristics, manifested in a decrease in dissolved oxygen concentration and saturation, an increase in pH value (due to increased peripheral coverage and photosynthesis), and water temperature (with almost no water flow, resulting in an increase in its kinetic energy). Compared to normal river beds, the richness and diversity of aquatic macroinvertebrates have sharply decreased. It was also found that the community structure of large invertebrates with weaker resistance to other more tolerant pollution has changed, leading to a loss of aquatic biodiversity and an increase in phosphorus concentration in the water generated by trout waste.
Hydroecological approach for an experimental well field in the Yucatan karst
Authors: Moguel C.E Zetina , Herrera R.A. González , Quintal I.D. Barceló
Published: October 2023

The experimental well field of FIUADY is a system of 50 m and up to 75 m deep wells. It was built with the purpose of confronting and consolidating the hydrological knowledge of groundwater in the karst plain of northern Yucatan. In this context, the objective of this work is to document the historical behavior of some variables of the physical-chemical and biological environment of the aquifer to sketch models of the habitat of the epikarst microbiota in the northern plain of the Yucatan peninsula. Hydrogeological conformation was documented through drilling debris analysis and underwater video recordings in the well. Measurements of temperature, electrical conductivity, pH and dissolved oxygen were made in October, November, January, February, March and April of different years. For statistical analyses, data were grouped into two periods: recharge (October and November) and discharge (January-April). The results include a schematic hydrogeological profile and statistical analyses of the variables. The minimum and maximum values observed are: temperature °C (26.64, 29.87), electrical conductivity µS/cm (465,46800), pH (6.14, 8.20) and dissolved oxygen mg/L (0.01, 7. 93). It is concluded that: a) in an area of a few square meters there are important variations in the hydrogeological characteristics; b) the hydrogeological behavior of the wells has to do with karstic horizons; their dimensions, connectivity, distribution, density and the way they influence different hydrological stresses; finally c) the presence of crustaceans in the wells and "anomalies" in the concentration of oxygen may have an explanation in biogeochemical processes of dark ecosystems.
Threat of non-metallic mining on the integrity of the Tocuyo River basin, Lara state, Venezuela
Authors: López Carelia  Hidalgo
Published: October 2023

There are various conflicts of usage in the Tokuyo River Basin of Lala Prefecture. The contradiction is that in a semi-arid and water scarce area, the soil has many natural resources, among which the most prominent are non-metallic minerals ((NMM), such as silica, the best clay and a series of decorative stones in the country. The public policies of the State and local governments prevail in this territory. They encourage NMM mining, therefore, criticism of an extractivist economy that has historically dominated the country arises. Through an exhaustive documentary review, results show that there are few references to environmental impact studies associated with NMM mining. There is evidence of open-pit mining near rivers and streams, which exposes areas to erosion and sediment production due to the typical erratic rains that affect the Tocuyo, Morere, Diquiva and Curarigua rivers. The promotion of mining activities by economic interests without the independent participation of environmental institutions puts the integrity of the basin at risk. The situation requires the activism of social movements to denounce the impacts that put, among other things, the future availability of water for human consumption and food production at risk.

O autor, após ressaltar a complexidade do problema da patologia óssea, devido à multiplicidade de tecidos que originam os tumores dos ossos, estuda as classificações propostas, especialmente à referente aos sarcomas, que constitui objeto do presente trabalho. A propósito, salienta o registro dos sarcomas ósseos, instituído pelo Colégio Americano dos Cirurgiões, cuja classificação é adotada pelo Serviço Nacional de Câncer. Em seguida, mostra as dificuldades de diagnóstico diferencial, quer clínico, radiológico ou histológico, entre as diversas afecções ósseas, tanto benignas como malignas, afirmando que somente o estudo daqueles três métodos em conjunto, poderá resolver satisfatoriamente os casos. Apresenta uma classificação resumida em 4 tipos que passa a estudar separadamente, abandonando as respectivas subdivisões, na prática, sempre cheias de dificuldades. Descreve, assim, de forma individual, cada um desses 4 tipos principais de sarcoma, tais como o osteogênico, o tumor de Ewing, o tumor de células gigantes (mieloplaxonias), o mieloma e os tumores secundários metastáticos, salientando as diferenças, entre os mesmos existentes, do ponto de vista clínico, prognóstico e terapêutico. Apresenta, a propósito, exemplos de casos de cada um desses tipos de tumores ósseos, extraídos do registro do Serviço Nacional de Câncer, confrontando os aspectos da sífilis óssea que pode com eles se confundir. Finalmente, estuda o valor da biópsia nos tumores ósseos, discutindo as razões pró e contra desse método de dignóstico.
Proteção em Radioterapia

Trabalho apresentado por ocasião da 1ª Jornada Brasileira de Radiologia. Nas três primeiras décadas, que se seguiram à descoberta dos raios X e do radium dezenas de pessoas pagaram com a vida o tributo, devido à super-exposição aqueles tipos de irradiações. Isto porque, não conhecendo bem os perigos a que se expunham, trabalhavam os pioneiros da radioterapia com meios insuficientes de proteção. Hoje em dia, graças aos notáveis trabalhos de Failla, Quimby, Taylor, Evans e Braestrup além de outros, onde são descritos os meios de proteção adequada para os raios X e radium, podem os médicos e técnicos trabalhar durante muito tempo com as irradiações sem sofrer os seus efeitos nocivos.

Published: October 2023

In this report to your society we have not presented our experimental data. We are reserving this more technical aspect for a publication in the near future, and in which due credit is given to the financial support and encouragement, that the Câncer Research Society of Montreal, has given to this research project. By means of the dropping Mercury electrode and by the pepsin, alcohol and sulphosalysilic acid, deproteinisation methods, we have determined the cystine content in various carcinomatic and non carcinomatic samples of blood serum. The maximum high of cystine wave for normal patient serum was 25 mm. and for carcinomatous serum from 35 to 46 mm. The present study, altho only explorating in nature has yielded results of such promise that it is our opinion, the inauguration of a research program on a larger scale is now in order. Polarography may become a new blood test in cancer diagnosis.

Tratamento do Carcinoma do Colo do Útero: Ensaio Crítico dos Métodos Usados nos Últimos 10 Anos
Authors: Fried Carl
Published: October 2023

A história do tratamento do carcinoma do colo do útero apresenta 3 períodos que se diferenciam quanto à orientação seguida: 1.° período: até 1920 — operações radicais; 2.° período: de 1920 até 1935 — afastamento gradual da intervenção cirúrgica a favor da radioterapia; 3.° período: de 1935 até agora — constituído pelo aperfeiçoamento dos métodos radium e roentgenterápicos, com certa tendência à associação cirúrgica em casos especiais. São numerosos os trabalhos publicados nos últimos 10 anos, explorando o assunto dos pontos de vista clínico e técnico. A abundância do material divulgado, a larga dispersão em revistas e as opiniões muitas vêzes controversas, tornam difícil uma orientação segura, a não ser que se faça uma revisão da literatura. Êste trabalho pretende apenas apresentar o panorama atual do assunto e, numa crítica desapaixonada, compor um quadro dos métodos e idéias dominantes, a fim de encontrar um caminho seguro no tratamento do carcinoma do colo do útero. Para se ter uma idéia da importância do problema, basta assinalar que nos Estados Unidos, entre 1941-44, 16.757 mulheres morreram por ano devido a câncer do colo uterino, elevando-se esta cifra, só em 1944, a 17.152.
Considerações Sôbre o Diagnóstico e Tratamento Cirúrgico do Câncer do Lábio

Published: October 2023

O presente trabalho baseia-se em 192 casos de carcinoma do lábio observados no Serviço Nacional de Câncer, no período de 1938 a 1949. A localização do câncer ao nível dos lábios permite, em geral, diagnóstico precoce e tratamento adequado em sua fase inicial, pois desde o início chama a atenção do doente, que quase sempre procura logo recursos médicos. Com exceção das lesões negligenciadas pelo próprio paciente ou inadequadamente tratadas, o câncer do lábio é passível, na maior parte dos casos, de tratamento eficaz e precoce. Consideramos como câncer do lábio apenas as lesões que se localizam na mucosa dos lábios ou em sua orla cutâneo-mucoca. Os carcinomas baso-celulares, que quase nunca têm origem nas mucosas, são habitualmente carcinomas cutâneos que podem invadir secundariamente a mucosa labial e como tal não serão aqui estudados.

Published: October 2023

The use of space maintainers in deciduous and mixed dentition is of significant importance as it helps prevent the development of malocclusions, including those resulting from early tooth loss, by preserving the necessary space for the eruption of permanent teeth. This study aims to report a clinical case of a 10-year-old female patient. The patient presented at the Pediatric Dental Clinic of the School of Dentistry at UFAM with the main complaint of dissatisfaction with her smile. During the anamnesis, the mother reported trauma to elements 51 and 61, and the clinical examination revealed prolonged retention of these elements and malocclusion. After the extraction of the retained elements due to delayed eruption of permanent teeth, the fabrication of a space maintainer appliance was indicated for esthetic and preventive purposes. A Hawley Plate was used for this purpose, and an acrylic tooth was added for esthetic purposes. After a 5-month period of appliance use, the central and lateral incisors erupted naturally in the mouth. This treatment approach resulted in the maintenance of the upper arch perimeter, providing the necessary space for permanent teeth to erupt, thereby preventing dental inclinations and space loss, avoiding the onset of deleterious oral and parafunctional habits, future complex malocclusions, and ensuring the patient’s aesthetic well-being.

Madracis spp. coral patches are the main deep–sea framework builder observed on the shelf–break scarp of the Colombian Caribbean, between 107 and 230 m depth. The Marine Protected Area, Corales de Profundidad National Natural Park, was established in 2013 to protect a site of high biodiversity associated with Madracis communities. Our research summarizes the advances in knowledge of its biodiversity as the result of four expeditions and offers insights into the state of its associated fauna. Madracis colonies occur in five areas of the park but corals thrive and build coral patches in only two of the five, both in the southwest area. Our surveys have resulted in the inventory of 337 species. Mollusca (116) dominated the fauna, followed by Bryozoa (70), Cnidaria (50), Echinodermata (39), Arthropoda (14), Annelida (13), Brachiopoda (3), and Chordata (32 fishes). Store voucher specimens at the Museo de Historia Natural Marina de Colombia–Makuriwa and metadata are available online in the SiBM database.

Ноосферні механізми взаємодії викладачів і студентів
Authors: Шарапановська Ю. В. , Єрмакова С. О.
Published: October 2023

адаптивне керівництво викладача у процесі професійної підготовки студентів розглядається нами як здатність педагога обирати й поєднувати різні стилі моніторингу професійної підготовки у контексті природовідповідності на засадах ноосферної парадигми проте залежно від освітньої ситуації. При цьому підвищення адаптивності керівництва досягається за рахунок, наприклад, переформування творчих груп, перепроектування завдань або модифікації навчальних курсів. Вищезазначене підтверджує, що джерелом адаптивного управління науковці вважають інноваційну модель організації професійної підготовки, яка вибудовується з фізичної природи, адже результатом процесів моделювання й конструювання є штучні системи, що тільки частково спроможні спрямувати розвиток за природнім шляхом

Створення сортів з високим продуктивним потенціалом, стійких до мінливих умов навколишнього середовища, є одним із першочергових завдань сучасної селекції. Мета дослідження. Порівняльна оцінка різних за висотою сортів пшениці м’якої озимої за довжиною головного стебла та окремими міжвузлями, а також встановлення особливостей їх формування і мінливості, залежно від метеорологічних умов та генотипу. Методи. У 2019−2022 рр. в умовах дослідного поля навчально-виробничого центру Білоцерківського НАУ досліджували сорти пшениці м’якої озимої, які відповідно міжнародного класифікатора РЕВ роду Triticum L., згідно даних оригінаторів, були розподілені на групи за висотою рослин. Біометричний аналіз проводили за середнім зразком 25 рослин у трикратній повторності, відповідно до загальноприйнятих методик. Результати. Формування міжвузлів стебла пшениці м’якої озимої у 2019–2022 рр. відбувалося в складних гідротермічних умовах, які суттєво впливали на їх довжину. Довжина порядкових міжвузлів різних за висотою сортів характеризувалась певними відмінностями. У середньорослого сорту І групи Лісова пісня частка другого, третього та четвертого міжвузлів була найменшою серед усіх досліджуваних генотипів – 8,6; 13,4 та 22,8% відповідно, при цьому визначено максимальний вклад колосоносного міжвузля – 51,4%. Високорослий сорт Одеська 267 відзначався найбільшим впливом третього та четвертого міжвузля – 17,6 і 26,9% відповідно, за найменшої частки п’ятого у формуванні довжини стебла – 40,4%. Висновки. Дослідженнями встановлено, що за однакових метеорологічних умов більшість низькорослих сортів ІІ групи і середньорослих І формують меншу довжину першого, другого і третього міжвузлів у порівнянні з середньорослими ІІ групи і високорослими. Водночас, максимальні показники першого-четвертого міжвузлів визначено в більшості високорослих сортів, а п’ятого в середньорослих І і ІІ груп.

Мета дослідження. Вивчення характеру успадкування довжини головного колоса в F1 за гібридизації різних за висотою сортів пшениці м’якої озимої. Методи. В умовах дослідного поля науково-виробничого центру Білоцерківського НАУ у 2019−2022 рр. досліджували 36 комбінацій схрещування, отриманих за гібридизації різних за висотою сортів пшениці м’якої озимої: низькорослі (66−80 см) − Білоцерківська напівкарликова (Б.Ц. н/к.), Сонечко, Смуглянка; середньорослі І групи (81−95 см) – Донська напівкарликова (Донська н/к.), Лісова пісня, Олеся, Колос Миронівщини (Колос Мир.); середньорослі ІІ групи (96−110 см) − Столична, Писанка, Відрада, Альбатрос одеський (Альбатрос од.); високорослі (111−125 см) – Одеська 267, Ластівка одеська (Ластівка од.), Пилипівка і Чародійка білоцерківська (Чародійка б. ц.). Насіння F1 висівали ручною сівалкою за схемою: материнська форма, гібрид, чоловіча форма. З гібридним поколінням працювали за методом педігрі Структурний аналіз проводили за середнім зразком 25 рослин у трикратній повторності, відповідно до загальноприйнятих методик. Ступінь фенотипового домінування (hp) довжини головного колоса у F1 визначали за B. Griffing (1950). Отримані дані групували за класифікацією G. M. Beil, R. E. Atkins (1965). Результати. За використання в якості материнської форми місцевих сортів, а саме низькорослого ранньостиглого Білоцерківська напівкарликова і середньорослого середньораннього Лісова пісня в більшості гібридів у 2020–2022 рр. формувались одні з найбільших показники (8,6–11,0 см) довжини головного колоса. За гібридизації материнською формою низькорослого сорту Білоцерківська напівкарликова, середньорослих Донська напівкарликова, Лісова пісня з низькорослими, середньорослими ІІ групи, високорослими І в переважній більшості успадкування довжини головного колоса у роки досліджень відбувалося за позитивним наддомінуванням. Висновки. Формування довжини головного колоса у гібридів пшениці м’якої озимої залежить як від підбору компонентів схрещування, так і умов року, суттєво впливаючи на показник ступеня фенотипового домінування, змінюючи тип успадкування. Найбільш поширеним типом успадкування довжини головного колоса в гібридів першого покоління, отриманих від схрещування різних за висотою сортів визначено позитивне наддомінування – 85,4 %.

Background:  The occurrence of a renal artery pseudoaneurysm after blunt renal trauma is an infrequent complication. The occurrence of delayed bleeding is typically observed within a period of 2 to 3 weeks following an injury and is commonly attributed to the presence of an arteriovenous malformation (AVM) or pseudoaneurysm. They are frequently observed in cases of injuries of greater severity or trauma that penetrates the body. The application of angiographic catheterization is efficacious in the detection of pseudoaneurysms in the renal artery. The management of renal pseudoaneurysms necessitates the consideration of distinct clinical associations, including the location and size of the lesion as well as the presence of symptoms.

Objective: The objective of this study is to provide a detailed account of the use of an angiographic catheter and embolization in the treatment of a patient afflicted with a post-traumatic renal artery pseudoaneurysm.

Materials and Methods: Conducting a literature review and medical records.

Results: A case of renal artery pseudoaneurysm is presented. A male individual aged 33 sought medical attention at the emergency department following a motorcycle collision and exhibited symptoms of pain in the right flank region. The individual underwent a medical intervention involving the placement of a double J stent. After a period of nearly fourteen days, the individual reported experiencing hematuria. The abdominal CT scan revealed a renal injury on the right side with an AAST grade of 4, while the renal CTA demonstrated the presence of a pseudoaneurysm. A pseudoaneurysm was observed at the renal poles on the right side through the use of an angiographic catheter. The procedure of selective embolization utilising coils was executed on the renal arteries located at the lower and middle poles of the right kidney.

Conclusion: The occurrence of renal artery pseudoaneurysms is infrequent; however, it is a grave complication that may arise from renal trauma. The accurate diagnosis and effective management of pseudoaneurysms are of paramount importance due to their potential to cause severe and potentially fatal complications if left untreated. The diagnostic process for pseudoaneurysms heavily relies on the involvement of the general radiologist. Interventional radiology provides alternative minimally invasive procedures that are linked to reduced morbidity and mortality rates and have replaced surgical interventions in the management of certain conditions.
