Abstract Background Coronary artery bypass grafting (CABG) surgery is a common procedure for managing multi-vessel coronary artery disease to revascularize the myocardium. Among the various conduits used, the left internal mammary artery (LIMA) is preferred due to its better long-term patency rate. However, CABG procedures involving LIMA may result in rare but serious complications, such as avulsion of the LIMA post-CABG, which leads to disruption of blood flow to the myocardium and the development of fatal cardiac tamponade. Case presentation We hereby present a unique case of spontaneous avulsion of a LIMA graft to the left anterior descending artery (LAD) away from the site of anastomosis, twenty-four hours following CABG surgery in a 67-year-old male patient. Emergency re-exploration and repair of the LIMA with interposition vein graft were performed and resulted in successful stabilization of the patient’s critical condition. However, this was followed by a complicated recovery period involving atrial fibrillation, acute kidney injury, and wound infection. Conclusion Avulsion of LIMA graft following CABG is rare, yet a fatal complication that requires high clinical suspicion and prompt management. Avulsion has been reported a few times in literature following both minimal invasive and conventional CABG. Understanding the etiology, clinical presentation, and management of this complication is crucial to avoid catastrophic outcomes.

The range of abstract concepts encountered when learning chemistry and the inability of students to make connections between the macroscopic, sub-microscopic, and symbolic representations, used in chemistry teaching, are believed to be the main reasons for students' difficulty when learning chemistry. Prediction and determination of molecular geometry using the theory of valence shell electron pair repulsion (VSEPR) is a sample of the abstract concept that is hard to understand by students who learn chemistry. Students may comprehend these ideas better if the learning process is supplemented with cutting-edge, interactive learning aids. To address the conceptual difficulties that students encounter when learning how to predict the shapes of molecules, a card game (MGCards) has been developed which is supported by simple molecular model building (MMB). The card game allows students to work through the steps required to predict the shape of a molecule in an engaging format. The student learning process is supported by feedback at all stages (if students make a mistake, they receive hints that will help them in the next step of the game). Action research with qualitative methods has been used to design, develop, and evaluate the MGCards. The MGCards and MMB were piloted at the University of Leicester with year one Natural Sciences students and modified based on the feedback received. Both MGCards and MMB were then used as part of the first-year chemistry education programme at Tanjungpura University in Indonesia. The findings of students' answer analysis (pre- and post-test) in both cycles showed that students had a better understanding after learning with MGCards and MMB. The positive feedback for MGCards and MMB confirmed that these resources were effective in delivering an engaging learning experience. The results suggest that MGCards and MMB play a significant role in enhancing students' understanding while also keeping them engaged.

The word slander is often spoken in society in everyday life, namely defamation. But in this study, the word slander in question is a trial for women and men. It is said in a hadith of the Prophet Muhammad. "I have not left behind a slander for humans which is more dangerous for men than (its slander) for women." Regarding this hadith, many people still understand it textually without looking at the content of the related hadith. Perceptions like this fall are accompanied by attitudes of blaming and defaming women. Therefore, the understanding of women's hadith as slander cannot be understood in general but must be understood by looking at the asbab al-wurud or fiqh al-hadith of the hadith. Because if you understand it just by looking at the hadith, women are indeed a dangerous source of slander for men, where a woman can be said to be slanderous if she cannot protect herself from things that are prohibited in Islam. This hadith is also considered valid. In this research, the author will discuss the analysis of the targeted hadith and what the scholars think about this hadith, which aims to increase knowledge, understanding, and insight for writers and readers in understanding hadiths, especially women, as slanderers. The method used by the author refers to the tahlili (analytical)/qualitative method in the form of library research.

This quantitative research with an experimental approach aims to determine the effectiveness of group counseling using a client-centered approach to increase the self-confidence of students who are victims of body shaming at MTs 2 Medan. The study population consisted of 150 students, and the sample was taken using purposive sampling. Data was collected by performing pre-tests and post-tests before and after the group counseling sessions using the client-centered approach. The data were analyzed using the Wilcoxon Signed Rank Test with SPSS. The results showed that after the group counseling sessions, there was an increase in self-confidence among the students: 5 students experienced an increase in self-confidence to the high category, and three other students experienced an increase to the very high category. The data analysis using the Wilcoxon Signed Rank Test revealed that the sig (2-tailed) value was less than 0.05, specifically 0.011, indicating that group counseling using the client-centered technique effectively enhances the self-confidence of students who experience body shaming.

Bahaya dan risiko kesehatan keselamatan kerja (K3) pada pekerja mebel kayu banyak berasal dari debu kayu dan bahan kimia seperti berbagai jenis cat, pelarut organik, dan lem kayu. Budaya kerja sehat selamat yang kurang serta tidak adanya proses komunikasi bahaya pada sektor informal ini, berpeluang munculnya penyakit akibat kerja (PAK) pada pekerja. Dari hasil wawancara bersama 4 orang mantan karyawan pekerja mebel, diketahui alasan berhenti bekerja karena mulai adanya gangguan pernapasan seperti muntah darah, batuk lama, berat badan menurun, dan napas sering tersengal atau sesak. Sehingga, mereka tidak sanggup lagi kembali bekerja di pabrik mebel setelah sembuh karena gejala dan penyakit dapat timbul kembali apabila terpapar debu dan bahan kimia yang ada di pabrik. Untuk itu, dilakukanlah kegiatan komunikasi dan edukasi untuk mengetahui jenis bahaya dan risiko keselamatan dan kesehatan pada pekerja disini dan cara pencegahannya. Kegiatan dilakukan tiga tahapan, dimulai dengan survei awal untuk identifikasi. Tahap kedua, pemberian komunikasi berbentuk edukasi pengenalan bahaya dan risiko di tempat kerjanya, cara membaca lembar data keselamatan bahan (LDKB), penggunaan alat pelindung diri (APD), dsb. Dari hasil komunikasi ini diketahui adanya peningkatan pengetahuan pekerja sebesar 22,25 poin (28%) yang dilihat dari nilai rata-rata pre-test 57 dan post-test 79,25. Tahap akhir, evaluasi implementasi setelah dua bulan kegiatan. Dari hasil pementauan diketahui bahwa masih sedikit pekerja yang mau menerapkan hasil edukasi terutama dalam penggunaan APD selama bekerja. Untuk itu, disarankan agar pemilik pabrik mebel menganggarkan dana untuk pembelian alat keselamatan yang nyaman serta mewajibkan pekerja menggunakannya selama bekerja.

Shrimp cultivation is a very profitable business in Gresik. However, shrimp farmers in Mojopuro Gede Village, Gresik admitted that they did not optimize their cultivation process. The farmer did not realize that water quality is essential to be considered in aquaculture. Based on these problems, the team held a community service in Mojopuro Gede Village, Gresik by introducing the water quality meter module and giving it to several shrimp farmers in the area. This activity was carried out so that the farmers can improve their cultivation process which has not been optimal and also introduce them to technological developments. Technology use in cultivation is expected to increase the quality of the farmers' crops. The implementation methods used in this activity are socialization and training. In this community service program, education has been given to the farmers so that they understand and care about the condition of their ponds in the cultivation process. The purpose of this program is for introducing the importance of technology in the cultivation process, even though it is actually not easy to provide education to shrimp farmers, especially traditional farmers. Therefore, related parties (NU Gresik Maritime Institute and Maritime Affairs and Fisheries Office of East Java Province) are expected to be more active in providing understanding to the farmers regarding the importance of applying technology in the cultivation process.

Euclidean geometry is a form of structural geometry grounded in a set of axioms from which all theorems are derived. This branch of mathematics encompasses two fundamental measurement types: angles and distances. It is widely recognized that the Euclidean axioms for measuring distances taught to students during primary, middle, and high school mathematics curricula establish the foundational concepts and structures of geometry they learn. The purpose of this article is to propose an educational resource that is designed for exceptional or gifted students in secondary school. This resource introduces alternative methods for measuring distances that differ from the Euclidean method. The objective of this educational material is to encourage students to think beyond the conventional Euclidean framework and explore alternative worlds of geometric structures. By broadening their horizons, students can recognize that geometric structures are not absolute but relative to the axioms and logical definitions that are agreed upon beforehand.

One of the factors that influence shrimp cultivation is the presence of algae. Precise knowing algae content in the pond is essential for effective management. Most research in the field of algae species carried out by researchers were observing Chlorella Sp. more than the other algae species, with a particular emphasis on substance concentrations. This study proposed non-invasive techniques for quantifying algae abundance, utilizing optical density (OD) and image processing (IP) methods. Three different algae species are frequently found in Indonesia i.e., Chlorella Sp., Thalassiosira Sp., and Skeletonema Sp. are used as sample. Those samples are cultured and prepared in a certain volume with a certain quantity. For experimental and observation purposes, those samples are then diluted into water based on percentage value. The experimental results provided RGB values, which were then used to establish polynomial equations. To verify these equations, two approaches were employed: synthetic image analysis and evaluation using additional data. The mean average error (MAE) was found to be 3.467 for IP method and 3.513 for OD method. It shows that IP method give better result compared to OD method in this study. However, it is very possible that the two methods will complement each other. [ABSTRACT FROM AUTHOR]

Purpose: This study investigates the influence of gantry and collimator angles on the dosimetric leaf gap (DLG) and leaf transmission factor (LTF) in a Varian LINAC equipped with rounded‐end multi‐leaf collimators (MLCs). While Varian guidelines recommend DLG measurements at zero degrees for both gantry and collimator, this research aims to address the knowledge gap by assessing DLG and LTF variations at different gantry and collimator angles. Methods: Measurements were conducted using a Varian TrueBeam LINAC with a Millennium 120‐leaf MLC and Eclipse TPS version 16.1. The beams utilized in this study had energies of 6 MV, 10 MV, 6 FFF, and 10 FFF. LTF and DLG were determined using ionization chambers in solid water phantoms at various gantry angles (0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315°). For each gantry angle, measurements were also taken at various collimator angles (0°, 45°, 90°, and 315°). Dosimetric impacts were evaluated through VMAT Picket Fence tests and patient‐specific verification using portal dosimetry for 10 clinical VMAT plans. Results: LTF values showed no significant variation across gantry and collimator angles. However, DLG values exhibited notable differences depending on the gantry angle and were independent of the collimator angle. The highest DLG value was observed at a gantry angle of 270 degrees, while the lowest was at 90 degrees. The AXB DLGAverage (averaging seven measurements of DLGs at different gantry angles) model demonstrated the best agreement between measured and calculated dose distributions, indicating the importance of considering averaged DLG values across multiple gantry angles for accurate dose calculations. Conclusion: Our study highlights the variability of DLG with gantry angle alterations, contrary to Varian guidelines recommending DLG measurements at zero gantry angle only. We advocate for utilizing an averaged DLG value from measurements across multiple gantry angles, as outlined in our methodology. [ABSTRACT FROM AUTHOR]

Along with developments in the maritime sector, especially on ships, the need for electric power on board will be very diverse. The use of diesel engines as power plants requires fuel to drive a diesel while the use of fuel in ships produced from petroleum processing is limited. Efforts to reduce the use of fuel is by implementing new renewable energy as independent electricity on ship. In EBT inverter technology plays an important role in converting DC voltage to AC voltage. In the inverter, the use of microcontrollers as drivers to generate PWM signals continues to develop. One of the developments of the microcontroller is ESP32. The problem that often occurs in inverters is that the output voltage is unstable. In addition to maximizing the performance of the inverter, it is necessary to add a protection system to reduce the risk of damage to the inverter or the load. Therefore, an inverter was made using the ESP32 microcontroller driver with the addition of protection and the fuzzy method as a voltage stabilizer. This inverter will change the 12 Vdc to 220 vac. In the Matlab simulation, the inverter can change the 12 vdc to 12 vpeak with a carrier signal of 20 khz and a reference signal of 50 hz. From the results of the inverter output will be changed to 220 vac using a step up transformer. The research overlay is being able to make a pure sine wave SPWM inverter using an ESP32 driver with a stable voltage.

Acetaminophen is widely used as a fever and pain reliever drug. However, acetaminophen intoxication was common and responsible for thousands of acetaminophen-induced liver injury (AILI) cases worldwide. It was understood that glutathione (GSH) depletion causes a deposit of acetaminophen metabolites which are toxic to liver cells. N-acetylcysteine (NAC), used as acetaminophen intoxication therapy, has been reported to cause side effects such as nausea, vomiting, and anaphylactic reaction. This narrative review aimed to discuss other potential candidates in AILI management. The biomolecular approach was used to investigate onion skin in-depth and holistic discussion. According to the results, onion peel extract is rich in flavonoids (quercetin and kaempferol) and potentially be a candidate in the management of AILI through proposed mechanisms such as restoration of reduced glutathione (GSH), inhibition of cytochrome P450 (CYP) enzymes, upregulation of uridine 5'-diphospho-glucuronosyltransferase (UGT) enzyme, and inhibition of TLR4 activity.

Abstract Background Postoperative pulmonary complications (PPCs) often occur after cardiac operations and are a leading cause of morbidity, inhibit oxygenation, and increase hospital length of stay and mortality. Although clinical evidence for PPCs prevention is often unclear and crucial, measures occur to reduce PPCs. One device usually used for this reason is incentive spirometry (IS). The aim of the study is to evaluate the effect of preoperative incentive spirometry to prevent postoperative pulmonary complications, improve postoperative oxygenation, and decrease hospital stay following coronary artery bypass graft (CABG) surgery patients. Methods This was a clinical randomized prospective study. A total of 80 patients were selected as candidates for CABG at An-Najah National University Hospital, Nablus-Palestine. Patients had been randomly assigned into two groups: incentive spirometry group (IS), SI performed before surgery (study group) and control group, preoperative spirometry was not performed. The 40 patients in each group received the same protocol of anesthesia and ventilation in the operating room. Result The study findings showed a significant difference between the IS and control groups in the incidence of postoperative atelectasis. There were 8 patients (20.0%) in IS group and 17 patients (42.5%) in the control group (p = 0.03). Mechanical ventilation duration was significantly less in IS group. The median was four hours versus six hours in the control group (p

Summary. Polydactyly is defined as an extra finger or toe that is present at birth. It is a congenital anomaly that can manifest as a single disorder or as a component of a syndrome. Treatment can be conservative or operative depending on the anticipated function of the extra digit. In this report, we describe a case of a bifid 5th digit on the right hand. The aim of this report was to report a new variant of type IIIB described by Duran (2015). This will possibly lead to the modification of the current classifications, which will improve the diagnosis and treatment of patients.

Although the field of classroom learning environments has undergone remarkable expansion and internationalisation, no study in Afghanistan in any subject area or at any educational level has ever adopted a learning environment framework or involved the assessment and investigation of classroom environments. Our study in Afghanistan included seven learning environment scales from the widely-used What Is Happening In this Class? (WIHIC) questionnaire, together with two scales assessing the student attitudes of Enjoyment and Self-regulation. After minor modifications to suit the Afghani context, scales were translated into Dari (one of the two dominant languages in Afghanistan) and then independently back-translated to check the accuracy of the original translation. Analyses of data from 1619 grade 10-12 science students supported the validity and reliability of the Dari-language scales. Past research in other countries was replicated in Afghanistan in that positive and statistically-significant associations were found between the learning environment and student attitudes. Some consistent patterns of gender differences and school-location differences (urban/rural) were identified.

Diabetes Mellitus is some metabolic diseases marked by hyperglycemia, which is caused by either insufficient insulin production, impaired insulin function, or both. This study aims to investigate the difference in platelet counts between patients with controlled and uncontrolled type II diabetes mellitus at Panembahan Senopati Bantul Regional Hospital. This study employed a quantitative approach, utilizing an observational method to collect secondary data. The study population comprised 100 samples. According to the conducted research, it has been found that patients diagnosed with type II diabetes mellitus predominantly experience elevated HbA1c levels that are difficult to manage. Additionally, the majority of these patients are female and have been dealing with the condition for more than five years. The data analysis utilizing the Mann-Whitney test concluded that there was no statistically significant difference in platelet levels between patients with controlled and uncontrolled type II diabetes mellitus. The study's findings demonstrate that the p-value = 0.084 (< 0.05). [ABSTRACT FROM AUTHOR]

Background: Coronary artery bypass grafting (CABG) surgery is a common procedure for managing multi-vessel coronary artery disease to revascularize the myocardium. Among the various conduits used, the left internal mammary artery (LIMA) is preferred due to its better long-term patency rate. However, CABG procedures involving LIMA may result in rare but serious complications, such as avulsion of the LIMA post-CABG, which leads to disruption of blood flow to the myocardium and the development of fatal cardiac tamponade. Case presentation: We hereby present a unique case of spontaneous avulsion of a LIMA graft to the left anterior descending artery (LAD) away from the site of anastomosis, twenty-four hours following CABG surgery in a 67-year-old male patient. Emergency re-exploration and repair of the LIMA with interposition vein graft were performed and resulted in successful stabilization of the patient's critical condition. However, this was followed by a complicated recovery period involving atrial fibrillation, acute kidney injury, and wound infection. Conclusion: Avulsion of LIMA graft following CABG is rare, yet a fatal complication that requires high clinical suspicion and prompt management. Avulsion has been reported a few times in literature following both minimal invasive and conventional CABG. Understanding the etiology, clinical presentation, and management of this complication is crucial to avoid catastrophic outcomes. [ABSTRACT FROM AUTHOR]
