Slowly Making Sense: A Review of the Two-Step Venom System within Slow (Nycticebus spp.) and Pygmy Lorises (Xanthonycticebus spp.)
Authors: Fitzpatrick Leah Lucy Joscelyne , Ligabue-Braun Rodrigo , Nekaris K. Anne-Isola
Published: August 2023

Since the early 2000s, studies of the evolution of venom within animals have rapidly expanded, offering new revelations on the origins and development of venom within various species. The venomous mammals represent excellent opportunities to study venom evolution due to the varying functional usages, the unusual distribution of venom across unrelated mammals and the diverse variety of delivery systems. A group of mammals that excellently represents a combination of these traits are the slow (Nycticebus spp.) and pygmy lorises (Xanthonycticebus spp.) of south-east Asia, which possess the only confirmed two-step venom system. These taxa also present one of the most intriguing mixes of toxic symptoms (cytotoxicity and immunotoxicity) and functional usages (intraspecific competition and ectoparasitic defence) seen in extant animals. We still lack many pieces of the puzzle in understanding how this venom system works, why it evolved what is involved in the venom system and what triggers the toxic components to work. Here, we review available data building upon a decade of research on this topic, focusing especially on why and how this venom system may have evolved. We discuss that research now suggests that venom in slow lorises has a sophisticated set of multiple uses in both intraspecific competition and the potential to disrupt the immune system of targets; we suggest that an exudate diet reveals several toxic plants consumed by slow and pygmy lorises that could be sequestered into their venom and which may help heal venomous bite wounds; we provide the most up-to-date visual model of the brachial gland exudate secretion protein (BGEsp); and we discuss research on a complement component 1r (C1R) protein in saliva that may solve the mystery of what activates the toxicity of slow and pygmy loris venom. We conclude that the slow and pygmy lorises possess amongst the most complex venom system in extant animals, and while we have still a lot more to understand about their venom system, we are close to a breakthrough, particularly with current technological advances.

Published: August 2023

Graft steatosis has been associated with inferior outcomes after liver transplantation. Given the rising prevalence of obesity and fatty liver disease, strategies allowing safe and successful utilization of fatty liver grafts are needed. Liver preservation by normothermic machine perfusion (NMP) allows reducing ischemia-reperfusion injury, extending preservation time and assessing graft viability prior to implantation into the recipient. NMP can be initiated at the donor hospital using a transportable device (referred to as upfront NMP or normothermic machine preservation) or after a period of cold ischemia (known as back-to-base). In this report, we present the case of a graft from an HCV-positive DBD donor with 70% macrovesicular steatosis, which was successfully preserved and transplanted using upfront NMP. This approach was key to minimize initial injury to the graft and allowed assessing its viability before transplantation, while improving transplant logistics. Upfront NMP represents a promising approach to enhance the transplantation of fatty liver grafts.

Community Strategic Visioning as a Method to Define and Address Poverty: An Analysis From Select Rural Montana Communities
Authors: Lachapelle Paul , Austin Eric , Clark Daniel
Published: August 2023

Community strategic visioning is a citizen-based planning process in which diverse sectors of a community collectively determine a future state and coordinate a plan of action. Twenty-one communities in rural Montana participated in a multi-phase poverty reduction program that culminated in a community strategic vision process. Research on this process was guided by alternative definitions of poverty and place attachment literature. Results from the qualitative survey data show many descriptions of poverty outside of traditional economic definitions and illustrations on the significance of place. Implications and recommendations on the use of visioning in other contexts in Extension are discussed.

Effects of High Level of Lead (II) Oxide (PbO) Usage on Accumulator and Response Surface Method
Authors: PIÇAKÇI Emrah , YALÇIN Zehra Gülten
Published: August 2023

This study involved the preparation of lead oxide paste for use in the production of lead-acid batteries. The paste was applied to the positive plates, and its performance effects were tested on the battery. Morphological and surface area analyses were conducted using SEM and BET, respectively, after the performance tests. Two mixtures of lead oxide ratios, 25%Pb-75%PbO (sample A) and 30% Pb-70% PbO (sample B), were used. The dough was applied to positive grids and passed through the curing process. SEM images revealed that tribasic sulfate (3BS) structures had a higher charge acceptance rate than tetrabasic sulfate (4BS) structures. BET analyses showed that the surface area of the samples with A ratio was higher than that of B. Electrical tests were conducted in the laboratory, and the A sample was found to be 12% more effective in the first charging efficiency than the B sample. Sample A was also found to be 67% more efficient in charge acceptance tests and 6.5% more efficient in cycle tests. The study also showed that increasing the %Pb ratio in the product decreases the initial charge efficiency, charge acceptance, and cycle life. Finally, the response surface method was used to examine the 2D picture of the relationship between lead percentage and yield, and it was found that the highest yield was obtained at 26% lead yield, with the yield being inversely proportional to the increase in lead percentage, likely due to the effect of particle size and surface area.

A GEOGRAFIA ESCOLAR E O CONHECIMENTO GEOGRÁFICO NO CONTEXTO DOS PARÂMETROS CURRICULARES NACIONAIS (PCNS)
Authors: CONCOLATO DA SILVA RHAFIC
Published: August 2023

The object of study is Brazilian school geography and geographical knowledge, analyzing its approach in the National Curriculum Parameters (PCNs). The PCNs emerged at the end of the last century as a response to the need for a single curriculum for the whole country, aiming to promote public educational policies throughout the national territory. The objective of this study is to evaluate the approach to geography in the PCNs, considering advances and setbacks. The concepts of landscape, place, territory and region are resumed, but there is a lack of consistent articulation of these concepts with the general objectives and methodological procedures. In addition, the economic approach receives little emphasis, and geopolitics is practically absent in the PCNs. The methodology used for this analysis consists of examining the PCNs guidelines in relation to school geography, identifying gaps, inconsistencies and progress from the perspective of two authors: Maria Encarnação Beltrão Sposito (1999) and Nídia Nacib Pontuschka (1999). The broader context of Brazilian educational policy is also considered, including the decentralization of guidelines, regional disparities and demands for quality education. The conclusion of this study reveals that the PCNs present advances and setbacks in the approach to geography for elementary school. Although there is a resumption of important concepts, such as landscape and place, the lack of consistent articulation and the absence of relevant themes, such as geopolitics, compromise the effectiveness of the guidelines. In addition, the importance of cross-cutting themes in the PCNs is highlighted, which address social, environmental, ethical and cultural issues in an integrated and cross-curricular manner
Error Analysis of a Sample of Kuala Kangsar University Students’ English Placement Writing Test
Authors: Mohideen Shamimah
Published: August 2023

Error analysis is a linguistic analysis that focuses on identifying and describing the learner’s error in target language learning. This study focuses on grammatical mistakes frequently made by students who took their English placement test after enrolment at Universiti Sultan Azlan Shah. Samples from the writing test were collected. The errors were identified, recorded, categorized and analyzed. The findings of this study shed light on the most frequently occurring types of mistakes made by a sample of Malaysian ESL learners of higher learning institutions. From this, the researcher can determine the learners’ problem areas. It is found that the most frequently occurring grammatical errors are errors in the inflexion of verbs according to tense and number. Students also made mistakes using the past participle for the perfect tenses and passive sentences. Many of these errors were mainly technical, which did not affect the intended meanings. These errors reveal Malaysian students' difficulties in mastering the English verb forms due to the significant differences between the Malay and English verb systems. To a certain extent, participants are influenced by their native language structure and transfer them when using the L2. Lack of familiarity with exposure and usage of the target language can be attributed to the errors. Frequently occurring mistakes need to be treated with the necessary intervention by instructors, and suitable learning strategies need to be practised by students to prevent fossilization.

Published: August 2023

Specifications grading is a student-centered assessment method that enables flexibility and opportunities for revision. Here, we describe the first known full implementation of specifications grading in an upper-division chemical biology course. Due to the rapid development of relevant knowledge in this discipline, the overarching goal of this class is to prepare students to interpret and communicate about current research. In the past, a conventional points-based assessment method made it challenging to ensure that satisfactory standards for student work were consistently met, particularly for comprehensive written assignments. Specifications grading was chosen because the core tenet requires students to demonstrate minimum learning objectives to achieve a passing grade and complete more content of increased cognitive complexity to achieve higher grades. This strict adherence to determining grades based on demonstrated skills is balanced by opportunities for revision or flexibility in assignment deadlines. These options are made manageable for the instructors through the use of a token economy with a limited number of tokens that students can choose to use when needed. Over the duration of the course, a validated survey on self-efficacy showed slight positive trends, student comprehension and demonstrated skills qualitatively improved, and final grade distributions were not negatively affected. Instructors noticed that discussions with students were more focused on course concepts and feedback, rather than grades, while overall grading time was reduced. Responses to university-administered student feedback surveys revealed some self-reported reduction in anxiety, as well as increased confidence in managing time and course material. Recommendations are provided on how to continue to improve the overall teaching and learning experience for both instructors and students.

Field courses for dummies: can ChatGPT design a higher education field course?
Authors: Tupper Mark , Hendy Ian W. , Shipway J. Reuben
Published: August 2023

We tested whether ChatGPT can play a role in designing field courses in higher education. In collaboration with ChatGPT, we developed two field courses; the first aimed at creating a completely new field trip, while the second was tailored to fit an existing university module. From our case studies, several insights emerged. These include the importance of precise prompt engineering and the need to iterate and refine prompts to achieve optimal results. We outlined a workflow for effective prompt engineering, emphasising clear objectives, sequential prompting, and feedback loops. We also identify best practices, including highlighting the importance of collaborating with human expertise, validating AI suggestions, and integrating adaptive management for continual refinement. While ChatGPT is a potent tool with the potential to save a significant amount of time and effort in field course design, human expertise remains indispensable for achieving optimal results.
Distribution of Reactive Energy Density around Antennas in Time-Harmonic Regime: An Electromagnetic Lagrangian Approach
Authors: Sarkar Debdeep , Antar Yahia
Published: August 2023

In this paper, we present an electromagnetic (EM) Lagrangian approach to quantify the reactive energy density distribution around generic antenna systems operating in the time-harmonic regime. First, we introduce the `period-averaged EM Lagrangian density' for radiating EM fields and present its intrinsic relations with the complex Poynting vector, total EM energy density, complex Helicity density, antenna reactive energy and radiation Q-factor. Furthermore, utilising full-wave MoM (method-of-moments) based MATLAB Antenna Toolbox, we compute contour plots of period-averaged EM Lagrangian density around thin-strip dipoles as well as printed microstrip patch antennas. It is demonstrated that such contour plots can not only distinguish between the capacitive and inductive nature of reactive energy density around multiple antenna systems, but also assist in the visualization of the links of inter-element mutual coupling via reactive fields. Such spatial maps of period-averaged EM Lagrangian density can be potentially useful for engineers working in the design of antenna arrays, MIMO (multiple-input multiple-output) and full-duplex systems, as well as EMI/EMC (Electromagnetic Interference/Compatibility) compliant devices.
The affirmative answer to Singer's conjecture on the algebraic transfer of rank four
Authors: Võ Phúc Đặng
Published: August 2023

In recent decades, the structure of the mod-2 cohomology of the Steenrod ring $\mathscr A$ has become a major subject of study in the field of Algebraic Topology. One of the earliest attempts to study this cohomology through the use of modular representations of the general linear groups was the groundbreaking work [Math. Z. \textbf{202} (1989), 493-523] by W.M. Singer. In that work, Singer introduced a homomorphism, commonly referred to as the "algebraic transfer," which maps from the coinvariants of a certain representation of the general linear group to the mod-2 cohomology group of the ring $\mathscr A.$ Singer's conjecture, in particular, which states that the algebraic transfer is a monomorphism for all homological degrees, remains a highly significant and unresolved problem in Algebraic Topology. In this research, we take a major stride toward resolving the Singer conjecture by establishing its truth for the homological degree four.
Potential Working Principle for a Static Charge and Static Magnetic Motor
Authors: Narasimhan Chandrasegaran
Published: August 2023

The document describes a potential (potential, it may never work) way to generate perpetual motion using static charge and static magnets. The magnets have to be manufactured in such a way to generate anisotropic magnetic field. The crux of the whole principle is whether anisotropic electric fields and anisotropic magnetic fields exists and whether that can be used to generate perpetual motion. In anisotropic fields, the energy you get out is greater than the energy you put in (that is the author’s prediction. He might be wrong about it). The author does not have the ability nor the infrastructure to test the idea. He wishes someone will do it for him. If the reader of this document thinks the idea is significant, please cite the author as a contributor of the idea. The author would like to be included as a co-author in such a work. The author would be surprised if it is a significant idea because so many people might have already thought about it and tried it.
Comparative Evaluation of Three-Phase Three-Level GaN and Seven-Level Si Flying Capacitor Inverters for Integrated Motor Drives Considering Overload Operation
Authors: Rohner Gwendolin , Gfrörer Tino , Bortis Dominik , Niklaus Pascal , Schweizer Mario , Kolar Johann Walter
Published: August 2023

Integrated Motor Drives (IMDs) are gaining popularity in industrial Variable Speed Drive (VSD) applications, thanks to their more compact realization and simpler installation. However, mission profiles of, e.g., servo applications, demand overload torques of two to three times the nominal value during several seconds, which is thermally challenging for the power electronics. Accordingly, high efficiency and power density of the inverter are of paramount importance for motor integration. Multi-Level Flying Capacitor inverters (ML-FCis) benefit from a reduced output filter volume and improved switching and onstate performance of low-voltage devices for increasing number of levels N, whereas the PCB overhead and gate drive volume increases. As shown in this paper, considering the performance of commercially available devices, the optimal number of levels for a 7.5kW IMD with an 800V DC link is N = 7 for Si and N = 3 for GaN semiconductor technology. A simple design procedure allows to dimension the 7L Si and 3L GaN FCi for 99% efficiency at nominal operation, while providing a high short-term overload torque (three times the nominal torque) also for low inverter output frequencies. A phase module of the 3L GaN FCi is realized as a hardware demonstrator of the IMD, whereby a detailed thermal model specifies its overload operating range, including, e.g., manufacturing tolerances of the setup and limited heatspreding in the power semiconductor cooling baseplate. The experimental analysis of the demonstrator verifies an efficiency of 98.94% and the practically required overload capability.

AoI-Minimal Clustering, Transmission and Trajectory Co-Design for UAV-assisted WPCNs
Authors: liu xiaoying , liu huihui , Zheng Kechen , liu jia , Taleb Tarik , Shiratori Norio
Published: August 2023

This paper investigates the long-term average age of information (AoI)-minimal problem in an unmanned aerial vehicle (UAV)-assisted wireless-powered communication network (WPCN), which consists of a static hybrid access point (HAP), a mobile UAV, and many static sensor nodes (SNs) randomly distributed on multiple islands to perform environmental mon?itoring. The UAV first is fully charged by the HAP, and then flies to each island to charge SNs and receive data from them. Before running out the energy in battery, the UAV flies back to the HAP to offload the received data and be fully charged again. Due to the finite battery capacity of the UAV, it is impossible for the UAV to traverse all the islands to collect all the data from SNs for once flight. We are thus inspired to divide islands into multiple clusters so that the UAV could traverse all the islands in each cluster. The key factors affecting the long-term average AoI contain the hovering duration, the flying duration, and the amount of data from each island reflected by the number of SNs on each island. Therefore, we formulate the long-term average AoI-minimal problem by jointly optimizing the transmit power of SNs, clustering of islands, and UAV's flight trajectory, subject to the battery capacity of the UAV. Since the optimization problem is NP-hard, there are no standard methods to solve it optimally in general. To tackle this problem, we decouple it into two subproblems: the power allocation subproblem for SNs, and the joint clustering of islands and UAV's flight trajectory design subproblem, which is much more perplexed and complicated owing to the tight coupling between them. To solve the first subproblem, we propose a hybrid TDMA and NOMA (HTN) protocol that takes advantage of the two protocols. To solve the second subproblem, we propose a clustering-based dynamic adjustment of the shortest path (C-DASP) algorithm, which is composed of three sub-algorithms, i.e, a proposed merging-aided K-means clustering (MaKMC) algorithm, the particle swarm optimization (PSO) algorithm employed to find the shortest path in each cluster, and a proposed dynamic adjustment (DA) algorithm taking into account the number of SNs on each island. Simulations are conducted to verify the effectiveness and superiority of the proposed HTN protocol and C-DASP algorithm.
Advancing Privacy and Accuracy with Federated Learning and Homomorphic Encryption

جهود المترجمين العرب في الاهتمام بحافظ الشيرازي وأساليبهم في ترجمة أشعاره

• هناك كثير من المترجمين العرب اهتمّوا بترجمة آثار حافظ الشيرازي، منهم: علي عباس زليخة،محمد نورالدين عبد المنعم، أحمدالطويلي ،كاظم كمونه، فخري بوش،نبيل كريم المندلاوي،سيد محمد صالح بحرالعلوم،محمد الأمين،عبد الكريم اليافي،مروان عطية،طلال مجذوب ،عبد الله خالدي ،محمد علي شمس الدين ...؛

• يري الأدباء العرب أنّ حافظ الشيرازي هو شاعر الغزل الأول في الأدب الفارسي بل في الأدب العالمي، طبقت شهرته الآفاق،و سارت بشعره الركبان،لما فيه من متعة روحية...؛وأنّ شعره مهرجان حقيقي للمعاني والصور والأفكار والأحاسيس يختلط فيه نواح البلبل بزغردات النسيم الذي يبادر إلي تقيبل أفواه الرياحين و التمسح ببتلاتها الوردية. و شعر حافظ أيضا تجلٍّ ناصع للآداب الإسلامية، و مظهر للصفاء و العشق الحقيقي، و صوت رائد للحرية و الجهاد و النهوض ضدّ عوامل الشر، فغزلياته من أجمل مجالي الفن و الكمال البشري الأمر الذي دفع المترجمين العرب إلى الإقبال علي ترجمتها يوماً بعد آخر, ومع وجود ترجمات متنوعة, تجدُّ ترجمات من آثاره علي مدار الزمن.

• يحتلّ الأدباء والمترجمون المصريون المرتبة الأولي من حيث اهتمامهم بحافظ وترجمة آثاره, كما كان للمصريين فضل السّبق،وما زال، في الجهود العربية التي بذلت وتبذل في خدمةالتعريف بجميع الشعراء الفرس القدامي منهم والمعاصرين.

• يعدُّ نصيب حافظ من اهتمام الأدباء العرب بالأدب الإيرانيّ ضئيلا جداً،تأتي أكثر الترجمات من آثاره في إطار مختارات من الشعر الفارسي وليس بشكل مستقل،ونحن نتمني أن يعتني الأدباء العرب بهذا الشاعر العظيم في العالم الاسلامي أكثر فأكثر، وأن يسعوا للتعريف به في العالم العربي على وجه الخصوص.

• توجَد في الترجمات العربية لديوان حافظ الشيرازي هنات كثيرة،منها الدلالية و الأسلوبية.وقد أجاد بعض المترجمين العرب في ترجمة أشعار حافظ من الذين يعرفون اللغة الفارسية جيداً مثل الدكتور فيكتورالكك.نظراً إلي أنّ أكثر مترجمي آثار حافظ يعرفون اللغة الفارسية، وقد ترجموا آثاره من اللغة الأم مباشرة و لم تخلُ ترجماتهم من بعض الهنات التي من شأنها الإضرار بقيمة أشعار حافظ فلا بد من أخذ هذا بالحسبان.

• أثّر حافظ الشيرازي في كثير من الأدباء العرب، و تجلّ هذا التأثير بشكل مباشر في أشعار بعضهم، نحو:محمد علي شمس الدين (الشاعر اللبناني)،حسين مجيب المصري(الشاعر و الاديب المصري) ونظم آخرون حول حافظ و كتبوا عنه مادحين له نحو:عبد الوهاب البياتي(الشاعرالعراقي المعاصر) وصلاح الصاوي (الشاعروالكاتب المصري) وغيرهم.

• لايمتلك بعضُ الدارسين العرب معرفة كافية باللغة الفارسية وقاموا بترجمة أشعارحافظ الشيرازي نثراً أو نظماً ولم يحالفهم النجاح أحياناً، منهم: عمرفروخ، عبد الكريم اليافي، أحمد زكي أبوشادي وجورج خليل مارون .

Published: August 2023

تعد السياحة الدينية ذات اهمية كبيرة من نواحي اقتصادية واجتماعية وثقافية وخاصة في مدينة مثل النجف الاشرف لما تمثله من مكانة قدسية لدى المسلمين على مستوى العراق والعالم لما لها من عمق تاريخي واسلامي.

فقد اكد البحث على دراسة مقومات السياحة في مدينة النجف ابتداءً من ابراز مكانة المزارات والمقامات الدينية فيها وعلى رأسها ضريح الامام علي عليه السلام وباقي المزارات والمؤسسات الدينية الاخرى.

كما اكد البحث على دراسة البنى التحتية التي من شانها الاسهام في قيام وتطور السياحة في هذه المدينة والتي شملت كل ما يحتاجه السائح من وقت دخوله الى مدينة النجف وحتى مغادرتها ،والتي تضمنت اماكن الاقامة ،والمطاعم، تطرق المواصلات،والمعالم التراثية والاسواق وغيرها.

وقدم البحث عدد من المقترحات التي من شانها تطور السياحة في هذه المدينة وفي مقدمتها اقتراح تطوير البنى التحتية للمؤسسات الدينة فضلاً عن مدينة النجف ككل وتثقيف المجتمع بأهمية السياحة الدينية بغية الترويج لمدينة النجف الاشرف سياحياً مما يترتب على ذلك من مردودات اقتصادية
عَبْدِ اللَّهِ بْنِ جُدْعَانَ التَّيْمِيّ ودَورُه فِي الْجَاهِلِيَّةِ
Authors: الابراهيمي المدرس الدكتور سلام
Published: August 2023

بعد الانتهاء بعون العلي القدير من هذه الدراسة التي كرست لدراسة " عَبد اللَّهِ بْن جدعان التَّيْمِيّ ودوره في الجاهلية "يمكننا إن نوجز أهم النتائج التي توصلنا إليها وظهرت جلية واضحة من خلال البحث وهي كالأتي :

1) يعد عبد الله بن جدعان من الشخصيات التاريخية المهمة والبالغة الاثر في تاريخ الجاهلية وله الاثر في قبيلته (بني تيم ) الا ان الروايات تباينت من حيث نشأته وتاريخ وفاته , الا ان المكانة التي كان يحتلها لدى ابناء قبيلته فكان لوفاته حدثاً مهماً واثراً كبيراً حتى مزجوا تلك الحادثة بالأساطير من خلال نعي الجن عليه ودفن في مكة.

2) بين البحث ان ابن جدعان اشتهر بعدد من الصفات التي كان يتمتع بها ومنها : المنادمة حيث اتخذ عدد من الندماء لانه كان من الاشراف وذو اليسر في الجاهلية والتي غالباً ما تكون المنادمة صفة ملازمة لهم.

3) اشار البحث الى اشتهار ابن جدعان بالكرم والانفاق على ابناء قبيلته واهل مدينته حتى اشتهر عندهم "بجفنة ابن جدعان" و"بحاسي الذهب" واكلاته الخاصة "كالفلوذوج " وكان له منادين ينادون الناس لتناول الطعام , واستمر الكرم حتى وفاته.

4) كان لابن جدعان دور بارز في حروب العرب في الجاهلية وخاصة ايام العرب في حرب الفجار , فكان دوره مؤثراً في تلك الحروب من خلال مد قبيلته بالسلاح وقيادتهم واطلاق سراح الاسرى من ابناء قبيلته بفديهم بالمال , اضافة الى دوره في عقد الصلح بين تلك القبائل المتحاربة , والى جانب هذا كان له دور في عقد الاحلاف وخاصة حلف الفضول الذي عقد في داره.

Latar belakang. Penyembuhan luka yang patologis dan pembentukan bekas luka patologis menimbulkan kerugian fungsional dan estetika. Keloid adalah bekas luka berlebihan yang tumbuh melewati batas luka aslinya yang merupakan kelainan fibroproliferatif. Keloid sulit untuk diobati karena sifat keloid yang rekuren dan terapi terhadap keloid yang masih belum sempurna dapat menyebabkan keloid semakin parah. Berdasarkan uraian diatas, studi literatur ini dibuat oleh penulis untuk menjelaskan tentang penyebab dan penanganan terhadap keloid. Metode. Artikel penelitian yang ditinjau berupa analytical review melalui data basePubMed. Hasil. Sebanyak 20 artikel penelitian terpilih yang sesuai dengan tujuan penulisan tinjauan pustaka ini. Kesimpulan.Penyebab utama keloid adalah trauma, cedera ataupun infeksi pada kulit. Monoterapi untuk keloid tidak disarankan karena tingkat kekambuhannya lebih tinggi dibandingkan dengan terapi kombinasi. Beberapa modalitas untuk pengobatan keloid adalah prosedur bedah, radioterapi, antitumor/antikanker, elektroporasi kalsium, kortikosteroid, tekanan magnetik intermitten, gel silikon, laser, Plasma Skin Regeration, dan penggunaan cryotherapy. Eksisi merupakan modalitas terapi yang memberikan pengurangan ukuran keloid secara instan, namun karena rekurensinya tinggi maka harus diberikan terapi lain sebagai terapi kombinasi, yaitu injeksi kortikosteroid ataupun radioterapi yang dapat mengurangi tingkat kekambuhan pasca eksisi.
