Authors: Kim Jung Chul , Yim Ga Won , Kim Young Tae
Published: January 2024

This study reviews the progress and recent advances in vaginal natural orifice transluminal endoscopic surgery (vNOTES) as a minimally invasive gynecologic procedure. The proposed advantages of vaginal natural orifice transluminal surgery include enhanced cosmesis due to a scarless procedure, better exposure compared with the pure vaginal approach, tolerable pain scores, fewer perioperative complications, and a shorter hospital stay. Recent advances in surgical instrumentation and technology have improved the feasibility of vNOTES as an innovative treatment option for gynecological conditions. However, technical challenges and training issues must be overcome before its widespread use. As a promising surgical innovation, further randomized comparative studies are required to clarify the safety and effectiveness of vNOTES in gynecology.

Published: January 2024

Purpose: Mechanical thrombectomy (MT) is the standard of care for acute ischemic stroke (AIS) due to large vessel occlusion (LVO). The choice of a transradial approach (TRA) for anterior circulation LVOs is still debatable; the use of a specific tricoaxial system could help mitigate numerous issues related to transradial MT.Materials and Methods: From November 2022 to November 2023, 22 patients underwent TRA-MT for anterior circulation LVOs, both as first-line and rescue from transfemoral approach (TFA) failure, with the same triaxial setup consisting of a 7F introducer sheath, 7F guide catheter, and aspiration catheters ranging from 5.5F to 5F in relation to the occlusion site. Choice of thrombectomy technique was at operator discretion. Patients’ demographic data, clinical presentation, treatment details, complications, rate of crossover to TFA, successful revascularization (modified thrombolysis in cerebral infarction [mTICI] score ≥2b), and good clinical outcome at 3 months (modified Rankin scale [mRS] 0-2) were reported.Results: Of 20 patients selected, 10 (50%) had occlusion of M1 segment of middle cerebral artery (MCA), 6 (30%) of internal carotid artery (ICA) terminus, and 4 (20%) with M2 MCA occlusions; 12/20 (60%) were right-sided occlusions and 8/20 (40%) were left-sided. The mean National Institutes of Health Stroke Scale score was 9.25 at admission. Successful revascularization to mTICI 2b-3 was achieved in 18/20 patients (90%). Intracranial complications were reported in 2 (10%) patients. Rate of radial artery occlusion at 24 hours was 10,6%; no access-site haemorrhagic complications were reported. Symptomatic intracranial hemorrhage occurred in 2 (10%) patients. mRS score 0-2 at 3 months was 50%.Conclusion: The high technical effectiveness and good safety profile of this specific tricoaxial setup for TRA-MT in AIS, even for large proximal LVOs, could constitute a viable alternative to TFA-MT in selected cases.

В настоящее время активно ведутся разработки инновационных медицинских методик восстановления утраченных функций пациентов, в которых особое значение приобретает использование биорастворимых (биорезорбируемых) материалов. К таким материалам относятся сплавы на основе Mg, Fe, Zn, которые позволяют заметно снизить травматичность и сроки лечения.Но у данных материалов присутствуют недостатки в виде низкой прочности и повышеннойхрупкости, что ограничивает их применение в медицинских имплантатах. Поэтому повышение механических характеристик биорезорбируемых сплавов является актуальной проблемой.Интенсивная пластическая деформация (ИПД) является одним из современных инструментов повышения свойств металлических материалов за счет существенного измельчения исходной структуры до ультрамелкозернистого или нанокристаллического состояния. Однимиз эффективных методов ИПД является метод равноканального углового прессования по схемеКонформ (РКУП-Конформ). В данной работе проведено исследование влияния технологических параметров на напряженно-деформированное состояние заготовки из биорастворимогомагниевого сплава марки МА-14 при обработке методом РКУП-Конформ. В рамках исследования проводились конечно-элементное компьютерное моделирование в пакете Deform-3Dи физический эксперимент на установке РКУП-Конформ. По результатам компьютерного моделирования было рекомендовано провести обработку РКУП-Конформ при температурах деформирования 150 и 200 °С на оснастке с углом пересечения 120°. В ходе экспериментальныхработ получены лабораторные образцы, предел прочности составил 305 МПа, относительноеудлинение при растяжении составило 25%.

Сплав системы Cu-Cr-Zr является перспективным высокопрочным электропроводным материалом. В свою очередь за счет существенного измельчения структуры методы ИПД позволяютзначительно увеличить механические характеристики. Поэтому исследование структурныхи фазовых изменений в данной системе сплавов в условиях ИПД представляет особый интерес. Известно, что деформационная обработка при температуре выше 450–500 °С может сопровождаться процессами рекристаллизации. Вид рекристаллизации в условиях деформациизависит от характеристик границ и зерен. В данной работе исследуется вопрос влияния исходного вида структуры на характер рекристаллизации в условиях теплого РКУП-конформпри 450 °С в сплаве Cu-0,6Cr. В качестве исходного состояния были использованы крупнозернистая равноосная, полученная после высокотемпературного отжига при 1050 °С и последующей закалки в воду, и полосового вида структуры, полученная методом волочения. Установлено, что в случае исходных равноосных зерен центрами рекристаллизации в процессе РКУПбудут являться преимущественно тройные стыки зерен. В случае вытянутых зерен наблюдалсяхарактер непрерывной динамической рекристаллизации. То есть зарождение рекристаллизованных зерен происходит вдоль вытянутых границ зерен. Основной причиной можно считатьболее напряженное состояния границ в исходной структуре после волочения.

В статье представлены результаты исследования многослойных (32 слоя) покрытий CrAlYN/CrAlYO полученных вакуумно-дуговым плазменно-ассистированным напылением на подложку из твердого сплава ВК8 (WC+8% Co). Исследовано влияние потенциала смещения подложки (Uсм: –50, –75 и –100 В) на фазовый состав, параметры кристаллической структуры, толщину, шероховатость, морфологию поверхности и физико-механические свойства. Рентгеноструктурным анализом обнаружено, что полученные многослойные покрытия имеют многофазную структуру, состоящую из фаз нитридов (CrN и AlN) и оксидов (Cr2O3 и AlYO3). При увеличении отрицательного потенциала смещения с 50 до 75 В наблюдалось снижение Cr2O3 с 52 до 18% и увеличение CrN с 26 до 39%, что привело к наименьшим микронапряжениям для обоих фаз (Δd/d×10–3 = 1,9). Размер ОКР всех фаз находился в пределах от 15 до 19 нм и практически не зависел от Uсм. Установлено, что увеличение потенциала смещения с 50 до 100 В приводило к уменьшению толщины формируемого покрытия и снижению шероховатости по критерию Rz, что свидетельствовало об уменьшении капельной фазы, подтвержденной оптической микроскопией. Обнаружено, что увеличение Uсм с 50 до 100 В приводило к повышению твердости (H) покрытий с 17,2 до 19,9 ГПа, однако, покрытие, полученное при 75 В обладало наивысшими значениями H/E и H3/E2. Методом рентгенофазового анализа с использованием синхротронного излучения обнаружено, что полученные многослойные покрытия CrAlYN/CrAlYO сохраняли термическую стойкость в процессе нагрева на воздухе до температуры ~1020 °C.

Published: January 2024

Advancements in gene transfer technology have indeed opened up exciting possibilities for more effectively manipulating the genetic makeup of live organisms, ranging from microorganisms to plants and animals. Direct and indirect transformations are the two basic types of gene transfer techniques. Indirect method comprises Agrobacterium mediated method as it involves intermediate host between gene of interest and target and this method is most opted one out of all present. Direct gene transformation methods, on the other hand, do not involve the use of an intermediate host organism. Instead, they rely on physical means to transfer genes between cells. Biolistic transformation uses high-velocity particles to deliver DNA into target cells, while microinjection and macroinjection involve the direct injection of DNA into cells. Protoplast fusion combines the genetic material of two different cells by fusing their protoplasts. Natural methods for gene transfer encompass mechanisms that occur naturally in various organism, includes transposition, conjugation, phage and retroviral transductions and bacterial transformation. Chemical techniques utilize chemical agents to facilitate gene transfer, such as calcium phosphate-mediated transformation, polyethylene glycol (PEG)-mediated transformation, DEAE (Diethylethanolamine)-Dextran-mediated transformation. Genes can be also being transferred using electrical techniques such as electroporation and electrofusion.
 Crop improvement and trait improvement are now being hastened by the fast-rising number of sequenced plant genomes, information from functional genomics data to understand gene function, innovative gene cloning, and tissue culture techniques. Despite being indispensable, its progress is still hindered by the fact that many plant species and agricultural genotypes exhibit low transformability or are resistant to established tissue culture and regeneration conditions. Here, we review the techniques employed in plant transformation and provide a concise overview of their evolution in agricultural crops, from their first inception to present time.

Authors: Scheinbart Lee , Nygaard Scott
Published: January 2024

Healthcare in the United States continues to face myriad challenges post-COVID, and institutions are at risk of organizational decline. A. O. Hirschman, one of many economists who have studied organizational decline, outlined several responses to organizational decline, collectively known as exit, voice, and loyalty (EVL). This article attempts to apply the EVL model to today’s health systems. We found that physician leaders are well positioned to evaluate physician peer attitudes and behaviors in today’s healthcare environments and can leverage Hirschman’s postulates to improve organizational resiliency and outcomes.

Published: January 2024

A banana é fruta amplamente consumida em todo mundo em virtude do seu sabor agradável, bom valor nutricional e preço relativamente baixo. A banana é um fruto considerado climatérico que possui tempo de prateleira consideravelmente curta necessitando de métodos de conservação que aumente o seu período pós-colheita. Um dos fatores que impossibilitam o Brasil de exportar a banana para outros países é a sua vida pós-colheita curta que não permite que os frutos cheguem verdes aos locais de comercialização. O permanganato de potássio vem sendo utilizado como uma alternativa para prolongar a conservação pós-colheita da banana por um maior período de tempo. O permanganato de potássio é um absorvedor de etileno dos frutos, ou seja, mantem o etileno em baixas concentrações dentro do ambiente de armazenamento das bananas. Diante disso o objetivo do presente trabalho foi avaliar o efeito de diferentes concentrações de permanganato de potássio associado a embalagem plástica na conservação pós-colheita de banana ‘Prata-anã’ clone: Gorutuba armazenada a 14,5 °C. O experimento foi realizado no laboratório de Fisiologia Pós-colheita da Universidade Estadual de Montes Claros utilizando-se frutos de banana ‘Prata-anã’ clone: Gorutuba. O experimento constou da utilização de quatro concentrações de permanganato de potássio: 0 g de KMnO4/1 kg de fruto (0 sachê), 0,5 g de KMnO4/1 kg de fruto (1 sachê), 1,0 g de KMnO4/1 kg de fruto (2 sachês) e 1,5 g de KMnO4/1 kg de fruto (3 sachês).  As bananas foram armazenadas em câmara fria a 14,5 °C e retiradas somente 25 dias após. Avaliou-se os frutos no dia do armazenamento, no 25° dia e por mais 4 dias, diariamente, em que ficaram em temperatura ambiente (25 °C). Como resultado foi verificado que o permanganato de potássio foi eficiente na absorção do etileno e em mantê-lo em baixa concentração dentro das embalagens conservando as características físicas e químicas da banana ‘Prata-anã’ clone: Gorutuba armazenada por 25 dias em temperatura de 14,5 ºC. A concentração de 1,5 g de KMnO4/kg de fruto promoveu maior retardo no amadurecimento dos frutos e as concentrações de 0,5 e 1,0 g de KMnO4/kg apresentaram resultados semelhantes entre si.

O objetivo deste artigo é debater sobre as comunidades Quilombolas no Brasil, com foco no Estado do Paraná, após a aprovação da Constituição Federal de 1988. Discute as relações de sociabilidade desses povos e como foi tratado o processo de reconhecimento de seus direitos, em especial de seus territórios o que gera e incorpora “nova” identidade cultural desses sujeitos. Amparado em uma abordagem qualitativa a partir de revisão bibliográfica e análise documental da legislação evidencia-se que os quilombolas continuam reafirmando a importância de sua identidade como um dos mecanismos para reivindicar direitos territoriais e étnicos via políticas governamentais. Outra constatação é que com a promulgação de alguns decretos a partir principalmente dos anos 2000, contribuíram para autoafirmação da identidade quilombola, conquista essa que traz ainda muitos desafios entre eles ainda prevalece o preconceito velado ou nem tanto, na sociedade brasileira.

Introduction: Cholera continues to be a growing concern in most developing countries. Cholera is an acute diarrheal disease endemic in India. Yet there are few reliable population-based estimates of laboratory-confirmed cholera in endemic areas around the world. The aim of this hospital-based study was to isolate and serogrouping of Vibrio cholerae in patients with diarrhea at tertiary care hospital, Ahmedabad during January 2021 to July 2022. Material & Methods: A retrospective study involving cases of acute watery diarrhea was done during January 2021 to July 2022. All stool samples from suspected cases were tested for Vibrio cholerae by standard microbiological procedures. Out of total 1294 stool samples Vibrio cholerae were isolated in 179 samples and sent to the NICED (National Institute of Cholera and Enteric Diseases) for serotyping and phage typing. Results: In present study rate of isolates of V. cholerae was 13.83 % (179 out of 1294 cases). V. cholerae O1 serotype Ogawa (78.77%) belonging to phage type 27 (54.74%) was the most common in the cases of acute diarrhea in present study. Conclusion: The present study identified serotype Ogawa and phage type 27 as the most dominant type and was found continuous in circulation throughout the study period. Phage typing is still an internationally recognized method of choice for characterizing circulating strains. This knowledge will be helpful to design a novel strategy to manage future cholera outbreaks. Keywords: Cholera, Vibrio cholerae, Serotyping, Phage typing

Background & Aims: The superior mesenteric artery syndrome (SMAS) is an uncommon syndrome characterized by the compression of the third part of the duodenum between the superior mesenteric artery (SMA) and abdominal aorta with resultant proximal duodenal dilatation. The radiological diagnosis of the SMAS is based on reduced angle and distance between the SMA and aorta in presence of proximal duodenal dilatation. A reduction in these is closely associated with depletion of the mesenteric fat between the vessels. Our primary aim is to establish the relationship, if any, of body mass index (BMI) with the angle and distance between the SMA and abdominal aorta in general population. Materials and Methods: This study was carried out in 200 patients who had undergone contrast enhanced computed tomography for various other complaints. Various parameters such as aortomesenteric distance (AMD) and aortomesenteric angle (AMA) along with the body mass indices were calculated. Pearson correlation coefficients were calculated to establish the relationship between BMI, AMD and AMA. Results: Pearson’s correlation coefficient for BMI and AMD was 0.868, indicating strong positive correlation and 0.577 for BMI and AMA, indicating moderate positive correlation. Furthermore, AMD and AMA also showed positive correlation with Pearson’s correlation coefficient of 0.568. Conclusion: There is significant positive correlation of BMI with AMD and AMA in general population suggesting people with low BMI are at an increased risk of developing SMAS.

Published: January 2024

Background: The distinction between incidental adrenal lesions is still difficult in diagnostic imaging whereas Dual energy CT has not been thoroughly tested for its ability to diagnose adrenal lesions. This study utilizes dual energy CT to identify between the two most prevalent adrenal neoplasms, adrenal metastasis and adrenal adenomas.Objective:To evaluate the efficacy of non-enhanced single-source dual-energy computed tomography (ssDECT) in differentiating metastases from adenomas in adrenal glands Materials and methods :This is a retrospective study conducted in the department of radio diagnosis of Mysore medical college and research institute after receiving the approval from our institutional ethical committee.A total of fifty six patients (32 men,24 women) with 31 adrenal metastases (AMs) and 32 adrenal adenomas (AAs) underwent a plain dual-energy CT imaging from March 2021 to October 2022 were included. The CT number from the virtual monochromatic spectral (VMS) image sets were measured for the AMs and AAs. The difference of CT numbers between AMs and AAs was statistically compared by P value and the box plot curve. Results: The CT number (medium, range) of metastases (50.47, 29.93 HU at 40 keV and 29.00, 9.36 HU at 140 keV) was significantly higher than that of adenomas (0.76, 33.04 to 13.73, 18.96 HU) at each energy level from 40 to 140 keV (P <.05).Conclusion: Using CT numbers obtained from virtual monochromatic images of single source dual energy CT can be used to differentiate adenomas from adrenal metastasis. The Median CT number of metastases was higher than that of adenomas at 40 Kev and 140 Kev. The median CT number of metastases decreased with increase in incident photon energy in Kev and median CT number of adenomas increased with increase in incident photon energy in Kev.

Gray Level Homogeneity Analysis: A Novel Approach
Authors: El Beghdadi Abdelhamid , Merzougui Mohammed , El Allaoui Ahmad
Published: January 2024

In this article, we propose a method that helps us to analyze the homogeneity of gray levels locally by calculating a coefficient for each pixel based on the nature of neighboring pixels. This principle of encoding pixels according to their adjacent neighbors is described the nature of the distribution of gray levels within the image and measures their degree of homogeneity locally. This allows us to detect the different regions of the image and their contours based on the coefficient of homogeneity of the gray levels. In addition, this allows us to exploit these homogeneity coefficients to restructure regions of the image, extract and enhance the image contours while reducing the noise present in the image. This homogeneity study principle has several functions in the study and analysis of image texture, as do other methods of homogeneity assessment, such as the local contrast descriptor (LCD) and the co-occurrence matrix

Published: January 2024

This study aims to get an overview of the development of Islamic Preaching through smartphones in the digital era. This study uses a qualitative method with a phenomenology design. This study examined the phenomenon of the booming of Preaching content on social media since Preaching through social media is currently in demand, as indicated by the emergence of a large number of the preacher, especially in Indonesia. The experience and motive of such phenomenon became the basis of this study’s analysis using phenomenological methods and Alfred Schutz’s theory. The results demonstrated a change in the Preaching of the preacher. The spirit of delivering Preaching (through writings) is based on two types of motives. First, individuals are eager (to) receive a blessing from Allah and be ‘ghirah.’ Second, the convenience and facilities available in smartphone technology have triggered the development of social media platforms that eventually support the delivery of Preaching.
