Authors:   College of Education, University of Alabama, 520 Colonial Dr, Tuscaloosa, Alabama 35401, United States, Sun Jingping
Published: January 2024

Science, Technology, Engineering, Arts and Mathematics (STEAM) education taught through Project- Based Learning (STEAM PBL) has expanded across 22 states in the United States in the last two years. The literature on STEAM teaching is just emerging with most of the studies having focused on descriptions of newly established STEAM schools and how the teaching methods have been incorporated in classrooms. These studies have mainly used qualitative research or case study design. While the majority of the studies have described what is going on in terms of STEAM teaching, little is known about what type of school leadership can best facilitate the implementation of STEAM PBL. This study explores this gap by examining the source, process, practices, and effect of teacher leadership in relation to the implementation of STEAM PBL. Data from 18 interviews with teachers in eight middle schools in a southern low-performing district point to the importance of ongoing, hands-on professional development, effective professional learning teams of teachers, and teacher leadership for the effective implementation of STEAM PBL teaching.

There is an increase in demand for teacher leaders to take on and lead the digitised change in the classrooms. However, there is still limited research on how ready teachers are to lead and manage online teaching during and post-COVID times, and hence this exploratory study investigates the challenges that teachers face in enacting e-leadership. To answer the question on “how do the process and development of the introduction of Home-Based Learning (HBL) influence teacher leadership in Singapore?”, through convenience sampling, this study used questionnaires to understand in-service teachers’ readiness to be e-leaders and the drawbacks in the development and introduction of the hybrid or e-curriculum. The study concluded that when building teacher leadership capacity, it is important for school leaders to set the direction, establish a culture of online learning, and develop e-champions to support e-pedagogies. E-teacher leadership can be described as hybrid leadership that consists of a blend of face-to-face and virtual leadership skills.

In literature, both teacher leadership and teacher burnout have been heavily studied. However, it is unknown to what extent teacher leadership makes a difference in teacher burnout, and whether school rurality makes a difference in between. This study fills the research gaps by conceptualising teacher leadership from both instructional and non-instructional dimensions and applying a quantitative method to large-scale national data. Findings revealed that (a) rural teachers presented higher levels of teacher leadership practices; (b) rural and non-rural teachers presented the same levels of burnout; and (c) both instructional and non-instructional dimensions of teacher leadership practices helped reduce teacher burnout in general, but rurality moderated the two effects differently, where instructional teacher leadership had a larger effect in non-rural schools while non-instructional teacher leadership presented a larger effect in rural schools. Discussion and recommendations for further research of teacher leadership and teacher burnout in rural schools are presented.

Medical students in their clinical phase face various academic and non-academic challenges affecting their achievement of expected competencies. Medical students who fail competency assessments are encouraged to enrol in a remediation programme. Due to COVID-19, remediation learning activities have been altered to distance learning. Unfortunately, studies on clinical remediation programmes are scarce. This study aims to explore the clinical clerkship remediation process during the COVID-19 pandemic to provide a reference for developing appropriate remediation programmes. This is a qualitative study with a phenomenological design. The remediation process was explored through focus group discussions (FGDs) and in-depth interviews. Five FGDs with regular students, five FGDs with remedial students, five in-depth interviews with clinical lecturers and five in-depth interviews with education coordinators were completed. Four themes were identified from the gathered data: academic and non-academic factors influencing the need for remediation, planning, learning activities and assessment, and evaluation of learning processes and outcomes. Remediation during the clinical phase comprises several critical steps, and following the remediation process, students demonstrated improved performance. To improve the quality of the remediation process, the factors underlying the need for remediation should be determined.
O inventário de plantas como possibilidade para a redução da cegueira botânica desde o ensino fundamental
Authors: Tatsch Helene Mochetti , Sepel Lenira Maria Nunes
Published: January 2024

As plantas são responsáveis pela sobrevivência da maioria das espécies. Apesar disso, mesmo com tamanha importância, os vegetais ainda são pouco valorizados na Educação Básica. Em um fenômeno descrito como “cegueira botânica”, as plantas são pouco percebidas em um ambiente natural ou na vida cotidiana. Neste trabalho, buscou-se analisar as manifestações da cegueira botânica e as possibilidades de superar esse fenômeno através da valorização do conhecimento da biodiversidade vegetal. Para esse fim, foi proposta uma atividade intitulada “Inventário Botânico”, destinada ao 6° ano do Ensino Fundamental e aplicada em uma escola pública situada na zona urbana de Santa Maria/RS. Para a análise dos possíveis efeitos da estratégia didática, foram aplicados instrumentos de pré-teste e pós-teste intitulados “Stop Vegetal”. A média no pré-teste foi de 18 espécies citadas, com desvio-padrão de 9,68. Já no pós-teste, a média foi de 23 espécies citadas e o desvio-padrão de 12,72. Os alunos demonstraram reconhecer um maior número de espécies vegetais após a aplicação do Inventário Botânico, passando a observar mais plantas em seu meio. Tal resultado sinaliza que atividades didáticas que contextualizam a botânica à realidade do aluno podem colaborar para a redução da cegueira botânica e o maior reconhecimento da biodiversidade vegetal.
Entre o Neotecnicismo Empreendedor e a Autoridade Docente
Authors: Betlinski Carlos , Kaloczi Juliana da Silva Lopes
Published: January 2024

O neotecnicismo empreendedor, compreendido como acesso e manejo às tecnologias de informação e comunicação em seu aspecto primário da socialização, somado a uma leitura pragmática das atividades sociais, influenciam os novos contextos educacionais. Nesta conjuntura, a autoridade docente entrou em declínio, uma vez que deste é retirado do papel central no processo educacional, sendo substituído, cada vez mais, por dispositivos tecnológicos. Também a sua autoridade como detentora dos saberes sobre os objetos dos currículos educacionais declina, na medida em que todos têm acesso à informação na palma da mão, por meio de smartphones, por exemplo. Ao analisar essa temática, no presente trabalho buscou-se responder à seguinte questão: entre o passado e o futuro, quais desafios se colocam para o exercício do ofício do educador no presente? Para responder a esse questionamento, realizou-se uma pesquisa bibliográfica, tendo como os principais referenciais teóricos Jean Jacques Rousseau (1995) e Hannah Arendt (2007).  A partir do entendimento do papel do docente, segundo as perspectivas filosóficas de Rousseau e de Arendt, atenta-se sobre os desafios enfrentados pelos educadores na sociedade contemporânea para exercer sua função social. Estas perspectivas filosóficas permitiram atribuir valor ao papel do educador nos novos contextos, reafirmando a figura do educador governante como autoridade social e pedagógica, responsáveis pela formação humana para a vida comum e para a sociedade democrática.

Displacement analysis and numerical simulation of pile-anchor retaining structure in deep foundation pit
Authors: Yin Xupeng , Ni Hongmei
Published: January 2024

Foundation pit excavation can cause settlement and displacement of surrounding existing buildings and roads. In order to study the influence of soil unloading on the surrounding buildings during pit foundation excavation, the application of a pile-anchor retaining structure in a deep foundation pit was studied, with the deep foundation pit project of Anhui Bright Pearl Mall as the research subject. Through theoretical analysis, field measurements, and FLAC3D numerical simulations, the supporting structure was comprehensively analyzed. A comparison was made between the measured displacement data and the numerical simulation results of the supporting structure and the surrounding environment during the excavation process of the foundation pit. The results indicate that the model results, obtained through the use of the FLAC3D software for numerical simulations, generally align with the field data. This approach can more accurately reflect the evolutionary laws of soil pressure and deformation during the excavation of the foundation pit. The maximum displacement of the horizontal displacement monitoring point in this project's foundation pit is 25.96 mm, which is less than the monitoring alarm value of 30 mm. The horizontal displacement monitoring of the sidewall of the foundation pit is crucial among them. An analysis of the three major causes of numerical deviation provides valuable insights for the design of deep foundation pit supporting structures.

Published: January 2024

Background:

Coronavirus Disease-19 has been spreading globally with the rise of many variants after being declared as a pandemic on 11th March 2020. There is a lack of scientific literature focused on fomite transmission of COVID-19, especially the potential of saliva as a contributing factor in the spread and diagnosis of COVID-19 in dental healthcare practice. Hence, the aim was to comprehend the level of awareness of dental health care professionals/practitioners (DHCPs) about the role of fomite route of transmission and the role of saliva in Coronavirus Disease-19 (COVID-19) infections.

Methods:

An electronic questionnaire using Google Forms was circulated online after ethical approval and validation to dental health practitioners in Saudi Arabia, via emails and social media platforms.

Results:

Three hundred and eighty-nine responses were recorded. The female DHCPs had statistically significant awareness of the fomite route of transmission among various dental health professionals (p=0.04) and dental students, and dental interns had the maximum awareness (p<0.05). The DHCPS preferred to learn and collect nasopharyngeal specimens by themselves for COVID-19 testing. Doctoral DHCPs had maximum awareness about WHO guidelines for social distancing, while dental nurses were more informed about infection control methods against COVID-19.

Conclusion:

DHCPs have adequate information about the fomite route of transmission and the role of saliva in COVID-19. Saliva specimen collection is specifically preferred for COVID-19 testing by dental assistants and hygienists for testing in the dental health center/clinic/university. The DHCPs and dental hygienists were less aware of the fomite route of transmission through asymptomatic COVID-19 infected patients.
An Overview on the Mechanisms of Myocardial Damage in Hypertension and the Diagnostic Contribution of Cardiospecific Troponins T and I
Authors: Chaulin Aleksey Michailovich
Published: January 2024

Hypertension (HT) is one of the most common cardiovascular (CV) pathologies and a key risk factor for the development of CV disease and its complications. There are two main etiopathogenetic types of HT: primary and secondary. As a result of HT, damage to many organs (heart, blood vessels, retina,
etc.) can occur. These organs are considered the main target organs in HT and assessment of their condition plays an important role for optimal management of patients with HT. Increased levels of cardiospecific troponins T and I, localized in the main type of myocardial cells (cardiomyocytes), may indicate myocardial damage. At the same time, the degree of myocardial damage may correlate with the degree of increase in cardiospecific troponins T and I. In recent studies, cardiospecific troponins T and I have established themselves as early and highly specific criteria for myocardial damage not only in myocardial infarction, but also in many other cardiac (
e.g., arrhythmias, endocarditis, myocarditis, takotsubo syndrome, or cardiomyopathy) and extra-cardiac (
e.g., renal failure, sepsis, or diabetes mellitus) conditions. Many authors suggest using cardiospecific troponins T and I as prognostic markers for the above pathologies. Thus, the determination of cardiospecific troponins T and I can provide additional diagnostic advantages in the management of patients with pathological conditions that damage the myocardium. The purpose of this article is to systematize information about the pathogenetic mechanisms of myocardial damage in HT and to consider the diagnostic contribution of cardiospecific troponins T and I for the management of patients with HT.

Published: January 2024

Background:

Young Patients with lung cancer represent a distinct subset of patients with this neoplasm. Young International studies show increased lung cancer rates in females, while the incidence in males continues to decline. There is evidence to suggest that this trend recurs in younger patients. We studied the effects of gender differences on the incidence of surgical stages of lung cancer in young adults and its mortality rate.

Methods:

This study is a retrospective review (2010-2020) of young adults (aged under 45 years) with surgical-stage of lung cancer. We calculated female-to-male differences in incidence rate ratios, tumor characteristics, surgical management, and survival. Cumulative survival curves were generated by the Kaplan-Meier method.

Results:

We examined 46 men and 24 women, under 45 years. Female patients were diagnosed at earlier stages. The proportion of stage IA disease was significantly higher in women than in men (46% versus 13%, respectively) (p=0.03). Women were more likely never smokers (42% versus 83%, p=0.02). A histologic subtype, females were more likely to have typical carcinoid tumors (13.54% versus 10.21% for males) (p>0.05). The largest histological type in men was adenocarcinoma (25.53% versus 4.16%, p>0.05). All the patients were operated. Three men had neoadjuvant chemotherapy and one was operated on for cerebral oligometastatic before his chest surgery. Adjuvant chemotherapy was given to 7 women and 21 men. Despite the small number of postoperative complications in our study (n= 8, 11.2%), the male sex was significant in predicting this complication (p<0.05). The mortality rate was 1.4%. The 5-year overall survival rates were 84% in men and 87% in women.

Conclusion:

Our study identified sex differences in the incidence and mortality rates for surgical lung cancers in young adults, but the biological and endocrine mechanisms implicated in these disparities have not yet been determined.
Education with local wisdom paradigm: Teaching patterns of religious tolerance in Mbawa Village Donggo District, Bima Regency, West Nusa Tenggara
Authors: Kurniati Iin , Muthohirin Nafik
Published: January 2024

This study aims to explore information related to the teaching pattern of religious tolerance, especially at the traditional Raju ceremony of the Mbawa Village community, Donggo District, Bima Regency. Mbawa residents are a diverse entity, both from religious and ethnic backgrounds.  There are three different religions believed by the local community, namely Islam (78%),  Catholicism (20%),  and Protestantism (2%); and there are three ethnicities they profess namely Donggo, Flores, and Ambon. This article uses qualitative research methods with a descriptive analytical approach that aims to explain field data systematically and accurately, especially regarding the pattern of teaching religious tolerance values at the Raju traditional ceremony of the Mbawa community. This article uses Yusuf Al-Qaradawi's thesis in his thought which emphasizes the importance of teaching the values of religious tolerance for a pluralistic society. According to him, the teaching of the value of religious tolerance needs to be given to the community intensively, without discrimination towards certain religions or ethnicities. This study also wants to explain the traditions and cultural heritage of the Mbawa people through Emile Durkheim's thoughts on the role of socio-culture in bonding the relationship between religious communities. Durkheim said that to unite a plural community there needs to be a social role in the unity of rituals and common beliefs held by all citizens.  This study concluded that the awareness of the Mbawa community to disseminate the values of tolerance in Raju traditional ceremonies through teaching patterns within families, educational institutions, and village and tribal government structures, succeeded in knitting positive relations between religious communities. Through the ceremony, residents also have a common awareness to coexist peacefully and nonviolently.

Polycystic ovarian syndrome (PCOS), a very common cause of infertility in reproductive age groups, has increased exponentially in the past few years registering 9% of cases annually worldwide. It is one of the most common syndromes which manifests hormone secretion and its activity. Insulin resistance, obesity, Vitamin and mineral deficiency, etc., are commonly associated with PCOS. Vitamin A is a lipid-soluble vitamin that is useful in antioxidant activity and steroid synthesis is known to prevent the occurrence of PCOS. Vitamin D, a steroid hormone originating from cholesterol is commonly known as “the sunshine vitamin,” is also one of the observed vitamin deficiencies in PCOS women. Supplementation of Vitamins in the diet is essential in the management of PCOS women. This review attempts to brief the role of Vitamin A and Vitamin D as an important agent to overcome the challenges of PCOS by reviewing the investigations of various authors about the potential role of supplementation of Vitamin A and Vitamin D in various model organisms and Randomised Clinical Trials (RCT’s).

Published: January 2024

Background/Aim: High complication rates during the perioperative management of sarcomas around the pelvis have been reported; however, few include the detailed clinical course or complications in the late postoperative period. Radiotherapy is a multidisciplinary strategy for treating sarcomas. However, irradiated bone and soft tissues show a permanent loss of repair and immunocompetence. We present a case of pleomorphic rhabdomyosarcoma of the thigh that resulted in acetabular collapse induced by radiation and intestinal perforation during long-term follow-up. Additionally, we discuss the risk factors for late complications and pelvic reconstruction methods. Case Report: A 75-year-old man presented with a 1-month history of a recurring fever. Ten years prior, he was diagnosed with pleomorphic rhabdomyosarcoma of the right thigh and underwent a wide resection and bipolar hip arthroplasty, followed by chemotherapy and radiotherapy. Radiographs showed central dislocation of the bipolar head. Computed tomography revealed free air in the hip joint and thickening of the colon wall. Colonoscopy revealed displacement of the bipolar head into the colon wall. Colon resection and hip disarticulation were performed, as the bipolar head was contaminated with intestinal contents. Currently, he is able to walk stably with a walker, and there is no evidence of recurrence or metastasis of the tumor. Conclusion: Irradiation of the periacetabular bone may induce resorptive destruction, resulting in future structural failure. Hardware should not be used for periacetabular bone reconstruction; the risk of pelvic organ damage should be considered when the acetabular collapse becomes deteriorated. Therefore, other reliable and permanent reconstruction options are required.

Published: January 2024

Background/Aim: Waldenström’s macroglobulinemia (WM) is a rare slow-growing B-cell lymphoma that is characterized by lymphoplasmacytic bone marrow infiltration and the production of monoclonal immunoglobulin M (IgM) paraprotein. In 5-10% of patients, WM undergoes transformation into diffuse large B-cell lymphoma (DLBCL), which is more aggressive, with poor prognosis and a low survival rate. Case Report: Α 69-year-old woman was diagnosed with WM in 2009. She received six cycles of chemoimmunotherapy and a remarkable remission was achieved. However, in 2013 the disease transformed into DLBCL. The patient received chemotherapy and after the completion of the first cycle of therapy, the disease was significantly minimized. At the end of the therapy, there was no evidence of disease, and the patient remains disease-free. The cytogenetic profile of the patient did not reveal expression of BCL2 apoptosis regulator, BCL6 transcription repressor, Epstein–Barr virus small RNA, syndecan 1 nor cyclin D1. According to a staging system based on the platelet count, lactate dehydrogenase and previous treatment for WM, the described patient was classified as being at intermediate risk with an expected 2-year survival probability of 47% after WM transformation into DLBCL. However, the patient unexpectedly exceeded these prognostic indications. Conclusion: The findings for this patient are of great interest compared with the existing literature which suggests that the survival and prognosis for patients with transformed DLBCL are not favorable.
Spread of Syphilis and Health Inequality of Patients in Montenegro at the beginning of the 20th century (Preprint)
Authors: Elezovic Dalibor , Aleksić Budimir , Radulović Ivan
Published: January 2024

BACKGROUND

Syphilis is an acquired or congenital sexually transmitted infection caused by the pale spirochete bacterium (Treponema pallidum). The Principality of Montenegro was a small underdeveloped Balkan state that was trying to build institutions and thus a health care system. The sources that were the subject of our analysis show that syphilis appeared and spread in Montenegro at the beginning of the 20th century and that it threatened the health of the population.

OBJECTIVE

The key goals of our work were to show the state of public health in Montenegro at the time of the spread of syphilis. To show how patients were treated unequally. To show the hard struggle in Montenegrin public health for its modernization.

METHODS

In the research we have used the original archival material of the state authorities of Montenegro, which is kept in the State Archives. These are documents from the period of the spread of syphilis, which originated in the correspondence of the main state authorities in the field of health. Following the principles of scientific methodology, we have selected official documents that give the most accurate picture of the spread of syphilis, health policy, and discrimination against those affected at that time.

RESULTS

From the documents of state authorities that were the subject of our analysis, we conclude that people suffering from syphilis were discriminated and that there were cases of them becoming homeless. In some cases, the presence of health inequality and the refusal of certain health institutions to accept them for treatment can be seen. Also, funds were not allocated for the treatment of syphilis patients, and institutions avoided treating them. However, due to the prevalence of syphilis and the danger of uncontrolled spread, the state was forced to provide free treatment to all patients in state hospitals and clinics. The Ministry of the Interior ordered to regulate the issue of prostitution because it estimated that the spread of the infection came from people who were engaged in the oldest trade in the world.

CONCLUSIONS

The spread of syphilis in Montenegro at the beginning of the 20th century threatened the public health of the population of this small and underdeveloped European country. Syphilis spread mainly due to disorderly conditions related to prostitution and inadequate education and health culture of the population. The health care system of the small, underdeveloped Montenegrin society was weak and unable to properly deal with the emergence of this dangerous disease.

Authors: Dwiutami Yanuarga Lalita , Suharno Suharno , Fajar Falah Mohammad Affan
Published: January 2024

Analog rice is an imitation of rice made with non-rice ingredients such as tubers and cereals as an alternative healthy food. However, the existence of analog rice has not been fully known and accepted by the public due to a lack of knowledge. The physical characteristics of analog rice do not resemble paddy rice and still have several attributes that interfere with consumer acceptance. Adding glucomannan to make analog rice is expected to improve product attributes. This study aims to determine the priority of product development attributes and produce analog rice with the best concept through high value. The method used in this product development is value engineering, which has five steps: information, creativity, analysis, development, and recommendation steps. The best concept for analogs is rice made from sago with an additional composition of 0.07 gram glucomannan flour and 7 ml pandan essence oil. Sago analog rice with 0.07 grams of glucomannan and 7 ml pandan essence oil has 83.74% carbohydrate, 3.02% fat, 4.53% protein, 8.15% water content, and 0.55% ash content.

Published: January 2024

This study was prompted by an earlier study that revealed the absence of gonads in all fish species caught around the Itoku tributary of the Ogun River, an area known for active textile activities. Thus, this study investigated the effect of textile wastewater on reproduction biomarkers in African catfish broodstock. Male and female broodstock were exposed to varying pre-determined concentrations (0ppb-T0, 0.5ppb-T1, 0.35ppb-T2, 2ppb-T3) of the textile wastewater for a period of 96 hours. Water quality parameters, seminal/ovarian hormones, metabolites, ions, oxidative, enzymes, and sperm viability were assayed. The water quality parameters of the wastewater indicated varying degrees of physical and chemical pollution. The values of hormones were significantly different (p<0.05) although a trend was not observed. Prolactin, however, showed a marked difference statistically across the treatments in the male broodstock while a reverse trend was observed in the female broodstock. The values recorded for seminal metabolites increased significantly compared to the control except for T3 for cholesterol and T1 glucose which were significantly lower than the control. In the female broodstock, the values for glucose and creatinine significantly increased compared to the control. Seminal ions evaluated showed significant differences across treatments. Except for T1, there was a significant reduction observed in the values of sodium, chloride, and calcium compared to the control. For ovarian ions, a significant increase was recorded across the treatments compared to the control. However, sodium recorded a significant decrease compared to the control except for T3 where the value was higher than the control. In the male broodstock, aspartate aminotransferase and alanine aminotransferase values were significantly lower compared to control while an opposite trend was observed in the female broodstock. The concentration of sperm and life- to-death ratio significantly reduced across treatments compared to the control. These results indicate that the textile wastewater altered the reproduction biomarkers in the male and female broodstock. The implication of this is that reproduction in fish might become a challenge in textile wastewater polluted Itoku tributary of the Ogun River.
AN OVERVIEW OF THE INTERESTS AND PERCEPTIONS OF EARLY-STAGE RESIDENT DOCTORS TOWARDS ETHICS AND MEDICO-LEGAL TEACHING METHODS IN A FACULTY OF MEDICINE
Authors: Kulsum Kulsum , Suryadi Taufik
Published: January 2024

Background: Ethics and medico-legal (EM) teaching must be carried out in a fun way so that resident doctors can more easily understand the material being taught. Conventional lecture methods are considered monotonous, so efforts are needed to find the best method that is most in demand by early-stage resident doctors so that learning objectives are achieved optimally. This study aims to describe the interests and perceptions of early-stage resident doctors toward EM teaching methods at the Faculty of Medicine, Universitas Syiah Kuala.Methods: This was an interventional study with a cross-sectional design conducted among early state resident doctors (n=54) with a self-administered online questionnaire. The participants of this study were early-stage resident doctors who had passed the EM courses. The participants were collected using the total sampling method. The participants were tested for seven teaching methods for seven EM materials. After all teaching methods were carried out, participants were asked to fill out a questionnaire.Results: A total of 54 participants were involved in this study.

Objective: To determine the microbial growth of Echerichia coli and Penicillium Italicum on polyethylene (PE) and screen for the activities of Manganese Peroxidase (MnP) and Laccase produced by the two microbial strain (Echerichia coli and Penicillium Italicum).
Methods: Polyethylene (PE) used were obtained from Elizade university dumpsite Ilara-mokin, Ondo State. The polyethylene (PE) were cut into tiny pieces, rinsed with distilled water and then used as the sole carbon source for the growth of microorganisms in an orbital shaker flask. Laccase and manganese (Mnp) peroxidase activity were assayed in Escherichia coli and Penicillium italicum spectrophometrically as they utilize polyethylene (PE) as a carbon source.
Results: Escherichia coli growth was at 0.002 at 0 h, rose to the exponential phase at 96 h, and declined to the death phase at 144 h. Penicillium italicum growth was at 0.004 at 0 h, rose to the exponential phase at 72 h, and declined to the death phase at 144 h. Laccase activity was 9.2 (U/ml) in Echerichia coli and manganese peroxidase (MnP)was 5.25 (U/ml) in Echerichia coli. Manganese peroxidase (MnP) was 10.643(U/ml) in Penicillium italicum while laccase activity was 9.5(U/ml) in Penicillium italicum.
Conclusion: Echerichia coli and penicillium italicum showed Manganese peroxidase and Lacasse activities as they utilized polyethylene (PE) as carbon source. Hence, they should be explored for biodegradation of polyethylene (PE).

The document expresses the importance of always having clean facilities under standards based on biosafety and equipment used by staff to prevent diseases in birds such as avian pox and reduce contamination through an environmental plaque study (Alvarez, 2022).
Pseudouridine in RNA: Enzymatic Synthesis Mechanisms and Functional Roles in Molecular Biology
Authors: Khan Adil
Published: January 2024

Pseudouridine, a common modified nucleotide, is prevalent in bacterial tRNA, rRNA, and snRNA. Initially identified in rRNA and tRNA, its presence extends to snRNA. Despite being the first identified and most prevalent RNA modification, its biosynthesis and diverse roles remain insufficiently understood. This extensively occurring modified nucleotide influences structural and functional attributes in various RNA categories. The isomerization process involves a carbon–carbon bond formation, and Pumilio family proteins (PUFs) are potential Ψ reader proteins. Pseudouridine, a ubiquitous constituent in structural RNAs, is notably absent in mRNA or viral RNAs. Its enzymatic isomerization occurs at the polynucleotide level, independently of cofactors. Compared to uridine, pseudouridine prefers the C3-endo conformation, enhancing stability in specific structural motifs. Evolutionarily conserved in major spliceosomal snRNAs, it plays a crucial role in spliceosome assembly and splicing. Pseudouridine (ψ), comprising 0.2–0.6% of uridines in mammalian mRNA, is enzymatically generated by pseudouridine synthases. Five pseudouridine synthase families orchestrate its site-specific isomerization. In eukaryotic and archaeal organisms, specific synthases rely on noncoding RNAs, like box H/ACA small nucleolar/scaRNPs. These modifications contribute to RNA structural stabilization and functional efficacy. In pre-mRNA and mRNA they guide splicing processes and protect against degradation, acting as a defense mechanism against viral infections. This review delves into the detection, structure, functions, and applications of pseudoridine in RNA. Methodologies like High-performance liquid chromatography, mass spectrometry, thin layer chromatography, enzyme-linked Immunosorbent assay, capillary electrophoresis, northern blotting, reverse transcript polymerase chain reaction and RNA bisulfite sequencing. establish a robust framework. Pseudouridine's roles in reinforcing RNA structures, modulating translation, and its potential in mRNA.

Chitra Banerjee’s Independence: A Searing Saga of Cultural Conflicts and Upheavals of Immigration from Women's Perspective
Authors: Bhardwaj Dr. Purnima , Kaur Rajandip
Published: January 2024

Chitra Banerjee's novel "Independence" is an innovative perspective about independence as a beacon of martyrdom on the golden occasion of India's 75 years of independence. To quote Amitav Ghosh: “ A spellbinding saga of the decolonization and partition of the Indian subcontinent, with a case of vividly drawn, compelling characters.” The novel delves into the tumultuous phases of human life, exploring themes such as the mob mentality, heinous attacks on women, and the clash of traditional, societal, and cultural norms during the partition of India. Throughout human civilization, issues like immigration, communal riots, and social and cultural conflicts have remained crucial topics of discussion. In today's world, multicultural societies are a result of global immigration. Migration can be seen as a determining factor in various aspects such as violent conflict, ethnic tensions, the expansion of national powers, and even economic growth or stagnation. Diasporic literature often highlights the problems and concerns faced by immigrants. Those who have migrated to a new culture often experience various forms of stress that can impact their cultural norms, religious customs, and social support systems. Adjusting to a new culture from one's own can be challenging, and cultural identity plays a significant role in this process, whether one is an immigrant or a native. This paper aims to explore the issues of cultural conflicts and immigration as depicted in Chitra Banerjee's "Independence." By examining the novel's portrayal of these themes, we can gain a deeper understanding of the challenges faced by individuals in multicultural societies and the impact migration has on their lives.
