Published: November 2024

Gomphrena pulchella, commonly known as the button flower, stands as an exotic ornamental species celebrated for its beauty in landscaping, fencing, and potted displays.  Gamma irradiation-induced mutation has emerged as a promising strategy for induced-mutant breeding. Nonetheless, the application of gamma radiation on G. pulchella remain limited. This study aimed to determine the optimal effective dose by radio sensitivity test and evaluate the effects of radiations on G. pulchella cutting. The cuttings of G. pulchella were irradiated using acute gamma at 0, 10, 20, 40, 60, 80 and 100 Gy. Each treatment consisted of 35 cuttings. The irradiated cuttings were then planted into a perlite medium and after 60 days, the number of survived cuttings, the number of new leaves and shoots, the length of new shoots and days to flower bud emergence were measured. The survival rate of cuttings decreased as the dose of radiation increased. The highest mean survival rate was 97% obtained from the non-irradiated cuttings (0 Gy) followed by 89% from 10 Gy, 94% from 20 Gy, 69% from 40 Gy, 54% from 60 Gy and 31% from 80 Gy and only 9% survival at 100 Gy. Higher radiation rates also decreased the leaves and shoot numbers, shoot length and fluorescent emergence. Based on the survival rate graph, the lethal dose 50% (LD50) value was 59 Gy. The results revealed that gamma irradiation had various effects on the growth of G. pulchella including vegetative and flower development. The value of LD50 will be used to determine the optimal effective dose for further radiation-induced mutation in G. pulchella research.

Selecting suitable tree species is one of the most important factors determining the success of rehabilitationinitiatives or projects in degraded areas such as ex-mining sites. The ability of selected trees to survive andestablish in these areas can be explained physiologically through examination of their leaves. Among fourspecies planted in May 2022 in an ex-tin mining area in Malim Nawar, Perak, this study has chosen to focuson the Eucalyptus hybrid due to its superior survival and growth. A total of four E. hybrid trees wereselected with an average height of 2.71 ± 0.65 m and collar diameter of 36.23 ± 8.75 mm. Five sun leavesand another five shade leaves were sampled from each tree for measurements of leaf area, moisture content,chlorophyll and plant efficiency. Sun leaf was found to have significantly higher (p < 0.01) length and widthcompared to shade leaf which contributed to a larger area for the sun leaf (28.40 ± 3.98 cm2) than that ofthe shade leaf (22.88 ± 5.16 cm2). Sun leaf also had higher chlorophyll content compared to shade leaf (p< 0.05). The Chl-a fluorescence analysis results indicated better photosynthetic performance in sun leaveswith higher PIABS and PItotal than shade leaves. Our findings thus showed the morphological adaptation aswell as physiological responses of sun and shade leaves of Eucalyptus hybrid when planted in an opendegraded area.

The endeavour to employ CO2 from natural sources to improve plant growth is often challenging, especiallyin tropical climates. While mycelium bags from the mushroom industry can generate CO2, they need indoorconditions with controlled temperature, high humidity, and low light. These conditions are not present inopen fields, leading to low CO2 production. Inspired by the ancient clay evaporative cooling device calledthe zeer pot, a new solution was developed to address this problem. The eventual design was a confinementchamber that housed the mycelium bags and the okra seedlings. The chamber conditions were sufficientlyconducive for the mycelium bags to produce an ambient CO2 level of around 800 ppm during the day. Theresulting okra seedlings under this high CO2 concentration of natural origin had a notable increase in overallbiomass accumulation (+ 277%), carbon assimilation rate (+103%) as well as improved water use efficiency(+95%) compared to seedlings grown under ambient CO2 level. These promising findings not only provedthe capability of mycelium as a natural CO2 generator but also as an additional economic potential for thefarmers to gain income from the CO2-enriched crops as well as the harvested mushroom bodies at the timeof mycelium bags maturity. Furthermore, this simple innovation opens the avenue for furtherinterdisciplinary research in other agricultural efforts to improve crop yield and quality.

Authors: Ahmadin
Published: November 2024

South Sulawesi, which we find today as one of the provinces in Indonesia, is a peninsula that has an important role in the country's maritime history. On the west coast of Sulawesi, there are several kingdoms that have an important role in the archipelago's shipping and trade activities. This is due to its position on the Indonesian shipping route from west to east or vice versa. Thus, when discussing the strip and the spice trade as an important commodity of the world, then the gait of the kingdoms in this region becomes interesting to study. This paper discusses several kingdoms involved in spice trade activities, such as the Gowa Kingdom, the Tallo Kingdom, the Siang Kingdom, the Tanete Kingdom, the Suppa Kingdom, and also the Bantaeng Kingdom. Although only the Kingdoms of Gowa and Tallo are considered to be at the forefront of trade activities, but some kingdoms that have abundant produce also play a role as suppliers of various commodities that can be exchanged for spices

E-Political Campaign in the 2014 Presidential Election in Indonesia
Authors: Yuliatiningtyas Solikhah
Published: November 2024

Until 2014, only members of the political and military elite have been elected as presidents in Indonesia. The new president, Joko Widodo (known as Jokowi) is the first leader from outside the establishment of political habits to be elected directly by citizens. It uses ‘Tri-angulation Methods’: in-depth interviews with prominent politicians/advisors from six parties, focus group discussion and Critical Discourse Analysis/CDA of e-campaigns. This paper to explain why Jokowi won the election, and what campaign strategies used. The findings show television still has the highest percentage of usage for campaigns, followed by social media. Two parties (Gerindra and PKB) which focused on e-campaigns, have successfully increased their electability, especially by gaining votes among young voters. Although Prabowo’s votes increased 35% but it couldn’t beat Jokowi’s votes.  There were four factors that caused Jokowi to win the presidential election despite a poor e-campaign from his party. Firstly, the shaping of his image by traditional media which influenced grass-roots society, people who don’t usually have access to the internet. This social fact has resulted in Jokowi becoming the most popular politician in Indonesia and being finally crowned as a presidential candidate by Megawati, the Chairman of PDI-P Party. Unlike Europe and US, traditional media had set out the public agenda to influence the election, in contrast with agenda aetting theory (AST) practice that is used widely. Secondly, the role of an Islamic Party (PKB) which nominated a vice president (JK) with Jokowi. PKB used integrated campaign strategies: traditional (involving 3000 Islamic scholars) and e-campaign methods managed by PKB’s 500 young cadres and 2 million volunteers. Thirdly, a strong role model of Muslim women in Nahdlatul Ulama (NU), the biggest Islamic organization in Indonesia. The PKB party, as part of NU, together with the Muslim women organization, succeeded in neutralizing black campaigns which attacked Jokowi’s religious integrity. Finally, unofficial e-media campaigns organized by PKB and civil society volunteers as well as feeding publications among traditional mass media were also considered to be a strong factor. Through this well managed combination of traditional and new media campaigns, Jokowi won 53.15 percent of the votes, 6.3 percent more than Prabowo’s 46.85 percent. It concludes with assessments of the importance of e-media to the presidential election campaigns of Jokowi and Prabowo, and of the value of social media in increasing political participation, especially by young people.

The social context in social media is determined by 'Business Budgeting on the Method Perspective' study of identifying problems at the level of social information services, through cost budgeting efforts in the context of rising inflation and elements of geopolitical instability manifested by buying and selling recession and social insecurity, especially for low-income residents. The purpose of this finding is to identify the problems of the current situation affecting the social status of citizens and the prospects for exploiting the costs of their evolution by introducing a quality index of social needs based on statistical and econometric forecasting methods. The alternative perspective method used is empirical, represented by special literature studies, data analytics, database consolidation, econometric modelling, prospective analysis, and economic forecasting. This social conceptualization in making rational discussions is determined by the degree of social security issues, prevention efforts in the context of creating inflation and elements of geo-political instability manifested by recession and social vulnerability, especially for residents with micro-regions. This study aims to identify the actual situation affecting the social status and the perspective of its evolution as an asset by introducing a social security index based on statistical and econometric prediction methods. This method uses natural experiences that represent specific literature studies and natural analysis, each of which 'business budgeting on the method perspective' consolidates the field of scholarly dates, field models of econometrics, prospective analysis and previous economics.
Understanding History: Its Meaning and Essence
Authors: Ahmadin
Published: November 2024

The recent emergence of various new approaches to study in the social sciences has resulted in the mixing of various scientific disciplines in their theoretical and methodological implementation. Thus, it is sometimes difficult for us to distinguish between one study of scientific disciplines and another, except to understand the scientific philosophy of each. In addition, history as a scientific discipline also experiences an increase in meaning in its learning, because history is only understood as limited to past events. This paper aims to explain various definitions of history, the purpose of studying history, and the essence of history. The benefits expected from reading this study are to gain an understanding of history conceptually and theoretically, especially for students and other parties interested in historical studies.

Published: November 2024

This paper presents an analysis of the Expanded Public Works Program (EPWP), one of the ‘Driven Controls’ Re-Branding Customer key policy initiatives intended to ease the burden of poverty or unemployment on the poor and unskilled. Historically, such programs have been used as assistance during short-term crises. Lately, many ‘Driven Controls’ Customers have adopted it for long-term structural challenges. This program study in the G-20 government is intended to protect women and youth. This paper uses a mixed methodological approach to determine the active participation of women and youth in EPWP and their opportunities to transition to the labour marketplaces. This study also solicits the views of EPWP participants (see also, active and former) and officials to obtain information that is not included in the program's official report. Analytical procedures involve document analysis, focusing on EPWP reports from phases One (1) to Three (3) of the programs. This study proposes two propositions: the need for public-private partnerships to address the challenges of unemployment in the country because independent policies for the government or marketplace are inadequate; new program design that separates job seekers from social protection beneficiaries. In its current form, the EPWP is designed as a grassroots poverty trap.

Authors: Habash Nicola , Park Jin , Lukasik Natalie , Abai Babak
Published: November 2024

Aortic dissection (AD) involves a tear in the intimal layer of the aorta that creates a false lumen within the aortic wall and can result in malperfusion of distal branch vessels. Herein, a comprehensive examination of malperfusion in the context of acute AD is provided, with a focus on the mechanisms underlying dynamic and static obstructions, their effects on branch vessel perfusion, and the diagnostic challenges they present. The use of endovascular strategies such as thoracic endovascular aortic repair (TEVAR), branch vessel stenting, and aortic flap fenestration are presented. We also discuss the importance of timely intervention through staged aortic repair to optimize organ perfusion and minimize adverse outcomes in high-risk patients. Additionally, hybrid repair highlights the complex pathology of AD with malperfusion. By integrating scientific evidence with clinical expertise, this chapter intends to serve as a valuable resource for clinicians seeking to improve the management of acute malperfusion in AD using endovascular techniques.
Paradoxical Agitation and Masseter Spasm During Propofol Procedural Sedation: A Case Report
Authors: Padaki Amit S , Uppal Prabhdeep , Perza Michael
Published: November 2024

Introduction: Propofol is an anesthetic agent commonly used in emergency department (ED) procedural sedation. It is often preferred in orthopedic procedures because of its muscle-relaxing properties. Rarely, however, it can induce agitation and muscle hypertonicity. Case Report: A 58-year-old man presented to the ED with a left ankle fracture-dislocation. Propofol was used to facilitate procedural sedation, but the patient became mildly agitated. Ketamine was used to achieve full induction, after which propofol was used again to facilitate muscle relaxation. Near the end of the procedure, the patient had opisthotonos and masseter spasm requiring bag-valve-mask ventilation and subsequent intubation. This reaction was ultimately attributed to adverse effects of the propofol. Conclusion: While propofol is generally well tolerated, it can potentially cause agitation, hypertonicity, and other side effects such as muscle spasms and seizure-like activity. Acknowledging and preparing for these risks can potentially improve patient outcomes.

Neuropathology of Severe Depression in Long COVID-19 Infection; Possible Roles for Astrocytes, Creatine Kinase and Lactate Dehydrogenase Activity
Authors: Bagheri Maryam , Salari Sajjad
Published: November 2024

Background: The incidence of depression has increased significantly during the COVID-19 pandemic. Some individuals infected with COVID-19 develop persistent neurological and neuropsychiatric symptoms approximately 12 weeks after the acute infection, a condition known as long COVID-19 syndrome. However, the underlying pathogenesis remains unclear. Glial fibrillary acidic protein (GFAP), creatine kinase (CK), and lactate dehydrogenase (LDH) are proteins abundant in the central nervous system (CNS), playing important roles in neuronal energy homeostasis. Objectives: This study aimed to investigate the correlation between serum GFAP, CK, and LDH levels and depression in patients with long COVID-19 syndrome. Methods: This cross-sectional study involved 150 patients (75 males and 75 females). The Beck Depression Inventory-II (BDI-II) was used, along with standardized peripheral serum assessments. Serum GFAP, CK, and LDH levels were measured using customized direct ELISA. Data were matched by age and sex, and analyzed using Spearman non-parametric tests to assess the correlation between variables. Results: The serum level of GFAP was significantly higher in both males and females with severe depression compared to those with mild depression (282 ± 3 pg/mL, 280 ± 2.9 pg/mL, P = 0.001). The mean serum CK level was 239 ± 24.05 U/L in males and 142 ± 18.08 U/L in females (P < 0.0001). Furthermore, a significant positive correlation was found between CK serum levels and Beck scores (r = 0.33, 95% CI = 0.176 to 0.469), with a similar pattern observed for LDH (r = 0.22, 95% CI = 0.042 to 0.358). GFAP, CK, and LDH levels were higher in male patients. Conclusions: This study identified potential neurobiological mechanisms in CNS-related long COVID syndrome, suggesting that elevated astrocyte activity, along with increased serum CK and LDH levels, may contribute to the neurobiological issues seen in depressed long COVID survivors. Men appeared to be more susceptible to these changes than women. Further research is essential.

Published: November 2024

Background: The global COVID-19 outbreak has posed significant challenges to public health. Social capital has emerged as a crucial social factor in mitigating the effects of COVID-19. Objectives: This study aimed to assess the social capital levels of patients diagnosed with COVID-19 and compare these levels between inpatient and outpatient cases. Methods: In 2021, a cross-sectional study was conducted at Ganjavaian Hospital in Dezful city, Iran, involving 428 COVID-19 patients. The participants were selected through a stratified random sampling method and divided into two groups: Inpatients and outpatients. Data were collected using a standardized social capital instrument, along with demographic information on variables such as age, gender, education level, marital status, and the severity of COVID-19 symptoms. Results: Among the COVID-19 patients, the social capital components of individual trust, cohesion/social support, and social trust/associative relations were measured at 3.24 ± 0.25, 3.15 ± 0.28, and 2.49 ± 0.41, respectively. Logistic regression analysis showed significant associations between patient status and age (OR = 1.47, CI 95%: 1.21 - 1.80), education level (OR = 2.64, CI 95%: 1.50 - 4.71), individual trust (OR = 3.40, CI 95%: 1.55 - 7.47), and cohesion/social support (OR = 3.03, CI 95%: 1.49 - 6.28). Conclusions: Outpatients demonstrated higher levels of social capital compared to inpatients, highlighting the critical role social capital plays in coping with illness. This disparity suggests that outpatients benefit from stronger social networks and support systems. Enhancing social capital for hospitalized patients could significantly improve their health outcomes.

They need to possess significant expertise in e-learning and tackle the obstacles associated with delivering education and utilizing Information and communication technologies within higher education. To effectively navigate these challenges and adaptations, professors need to equip themselves with new educational techniques through training and readiness to adeptly incorporate emerging technologies into their teaching practices, thus enhancing the educational journey for students. By identifying, understanding, and ranking professors' requirements and preferences, effective and diverse educational initiatives can be tailored to meet their needs. Objectives: This research aimed to recognize the educational needs of medical science professors in the field of e-learning from the experts' point of view and prioritize these needs utilizing the analytic hierarchy process (AHP). Methods: This practical study was conducted in 2022 using a process-oriented approach and AHP. The main stages included the creation of a hierarchical structure, comparative judgment, and determining priorities. In the first step, 13 criteria were identified, which were derived from scientific articles and previous research. In the second step, the pairwise comparison matrix was used for comparative judgment, and the weight of each criterion was calculated. The third step involved determining priorities based on the weight of each criterion and the inconsistency ratio. The participants of this study included professors of basic and clinical sciences from different faculties. Results: The results of this study demonstrated that from the point of view of experts and participants, among the 13 criteria, the skills of virtual teaching (with weights of 0.146 and 0.148), electronic content production (with weights of 0.093 and 0.092), and holding online training courses (with the weights of 0.092 and 0.100) formed the three main needs of medical science professors in the field of e-learning and had the highest degree of importance and necessity compared to other criteria. Conclusions: Identifying the educational needs of medical science professors for organizing and designing necessary programs to enhance knowledge, skills, and empowerment will lead to improving the quality of e-learning, and eventually, reducing professors’ concerns in this area.

: The primary objective of this systematic review was to determine the efficacy of mindfulness-based therapy in improving the quality of life for individuals diagnosed with Irritable Bowel Syndrome (IBS). Following the PRISMA guidelines, a comprehensive literature search was conducted using major databases, including PubMed, Web of Science, Scopus, PsycInfo, CINAHL, and Cochrane Library, for clinical trial articles published between 2010/01/30 and 2024/05/30. The search strategy incorporated keywords such as "IBS," "Mindfulness," "quality of life," and "anxiety." The systematic review included 20 studies, with sample sizes ranging from 3 to 95 patients. A meta-analysis was subsequently performed on ten articles, focusing on the impact of mindfulness-based therapy on enhancing the quality of life in IBS patients. The Verhagen quality assessment checklist was used to qualitatively evaluate these articles. The study's findings were presented in two main sections using the random-effects model during the meta-analysis. First, the influence of mindfulness-based therapy on patients' quality of life was examined. The results showed a statistically significant improvement in the quality of life following this therapeutic intervention (Standardized Mean Difference [SMD] = -0.683, 95% Confidence Interval [CI] = -1.326, -0.039, P = 0.000). Additionally, mindfulness-based therapy significantly reduced anxiety (SMD = 0.679, 95% CI = 0.354, 1.004) and depression symptoms (SMD = 0.496, 95% CI = 0.284, 0.708) in these individuals. The findings of this systematic review suggest that mindfulness-based therapy is effective in improving the quality of life for individuals with IBS, while also reducing symptoms of depression and anxiety. Given the potentially harmful side effects of pharmacological treatments for these patients, it is essential to prioritize therapeutic and non-pharmacological interventions, such as mindfulness-based therapy.

Background: Nosocomial sepsis is a leading cause of morbidity and mortality worldwide. Understanding the antibiotic susceptibility patterns of pathogens specific to each geographic region is essential for effective patient management. Methods: This cross-sectional study aimed to investigate the microorganisms causing nosocomial sepsis and their antibiotic sensitivity in patients admitted to three referral hospitals in Isfahan, Iran. Clinical information and blood culture results were obtained from hospital records. Results from patients without signs of sepsis, as well as contaminants and community-acquired isolates, were excluded. Stratification was conducted based on sex and age (< 20 and > 20 years) categories. Results: In this study, 267 patients with hospital-acquired sepsis were identified, with gram-negative bacteria accounting for 77.2% of infections. The most common pathogens included Klebsiella spp. (35.2%), Acinetobacter spp. (21.7%), Enterococcus spp. (13.5%), Escherichiacoli (8.6%), Pseudomonasaeruginosa (8.6%), and Staphylococcusaureus (8.2%). The highest resistance among gram-negative bacteria was observed with cefepime (80.3%), ceftazidime (76.5%), cefotaxime/ceftriaxone (70.0%), trimethoprim-sulfamethoxazole (68.6%), ciprofloxacin (68.2%), meropenem (60.0%), and amikacin (50.3%). All gram-negative isolates were sensitive to colistin. Among gram-positive bacteria, the highest resistance was to ciprofloxacin (77.3%), ampicillin (75.7%), clindamycin (74.4%), vancomycin (64.9%), and gentamicin (30.0%). All gram-positive isolates in this study were sensitive to linezolid. Conclusions: The study indicates a high level of resistance among bacterial agents causing nosocomial sepsis in the studied area. Consequently, treatment may necessitate the use of last-line antibiotics, such as linezolid and colistin.

the article examines modern foreign and domestic approaches to scientific research and description of the phenomenon of induced alienation of a parent and other family members in conditions of conflict and parents separation, usually associated with divorce. An overview of existing scientific approaches to the study of the pathological adaptation of a child to divorce, conflict and parents separation is presented. The abnormal mental state that arises in a child in conditions of intra-family conflict and parents separation, characterized by a rejecting attitude towards a separate parent and other family members associated with the rejected parent, up to the complete cessation of any contact with them, manifests itself at the cognitive, affective and behavioral levels. It is proposed to consider this phenomenon through the prism of a psychological syndrome. The definition of the psychological induced family alienation syndrome is given. The article describes the situation of interpersonal development, the dramatic triangle of family members in conditions of induced alienation, the sources of the syndrome and the core of the syndrome. When describing the sources of the syndrome, the causes and models (forms) of alienating behavior of the initiator of alienation, the parent-inducer, and the alienator are indicated.
