Authors: Pishkar Seyed Edalat , Nejat Seyed Hassan , Zarei-Yazdeli Mohadeseh , Khadem Estarki Neda Sadat
Published: September 2024

Background: Enterococcus faecium is of great importance among Enterococcus species due to its antibiotic resistance and biofilm formation. The ability to form a biofilm on living surfaces is considered one of the most important pathogenic factors in this bacterium. E. faecium is involved in endocarditis, urinary tract infection, dental root infections, and eye infections by forming biofilms. Various factors, including the antibiotic resistance of E. faecium and the expression of genes involved in pathogenicity and biofilm formation, are involved in the stability of this bacterium in different conditions and the spread of infection. Objectives: Considering the special importance of E. faecium in biofilm production, the aim of this study was to review the presence and role of genes effective in biofilm formation in E. faecium bacteria. Materials and Methods: PubMed, Embase, and Web of Science databases were searched using the keywords "genes", "biofilm formation", "Enterococcus", and "quorum sensing". Studies that investigated the role of genes in the occurrence of biofilm in E. faecium were also included in the study. Results: Biofilm formation in enterococci involves a complex interaction of genes and virulence factors, including gelatinase, cytolysin, secreted antigen A, pili, and MSCRAMMs (microbial surface components recognizing adhesive matrix molecules). Polysaccharides also play a role in enterococcal biofilm formation. They are secreted in the form of capsules or exopolysaccharides. The genes involved in the production of polysaccharides include Sal, atn, epa, DltA, ebpABC, and bee. These genes increase the production of biofilm and attachment to the extracellular matrix. Quorum sensing, a process of intercellular communication, mediated by peptide pheromones such as Cob, Ccf, and Cpd, by targeting gene expression and regulation, plays an important role in biofilm development. The Fsr locus contains fsrA, fsrB, and fsrC genes. Furthermore, the regulation of extracellular DNA (eDNA) release has emerged as an essential component in biofilm formation. Conclusion: Biofilm formation in E. faecium is dependent on a large number of factors, including multiple genetic factors, a series of environmental conditions, and also a series of environmental signals, many of which need to be identified and researched. A complete understanding of the role of genetic and environmental factors involved in biofilm development may lead to the improvement and development of strategies for biofilm control in enterococci.
The Obstacles Encountered by Immigrants and their Cultural Assimilation in Bharathi Mukherjee’s Short Story “A Wife’s Story”
Authors: Archana Devi M
Published: September 2024

While replacing to a new country can be a wonderful experience, there are many challenges and adjustments required. Language barriers, cultural adjustment, job opportunities, education access, financial instability, and lack of family support are a few of these. Migration often causes conflict when cultures clash. However, migration has many positive cultural effects on both the migrants and the local population in the areas where they settle. Migration is a double-edged sword for migrants. Whether or not they choose to migrate, they are unlikely to wish to lose their culture. When immigrants to the US move out of ethnic communities and into more broadly defined “American” spaces, they could try to put their memories of their home countries behind them in favour of “becoming American.” In the past, they discovered that assimilation aided in their access to homes, employment, education, and other resources.“A Wife’s Story” was included in Bharati Mukherjee’s 1988 National Book Critics Circle Award-winning The Middleman and Other Stories. Since then, it has been included in several feminist and international literary anthologies featuring short fiction. Like many of Mukherjee’s writings, the story explores the nuanced and frequently contradictory experiences of South Asian immigrants adjusting to life in the United States. It also covers how other immigrant groups and Americans, some of whom have only been in the country for a generation or two, have reacted to these South Asians, who Mukherjee refers to as “the new pioneers.”The short story “A Wife’s Story” centres on the experiences of an immigrant Indian woman to the United States. The story is told from Panna’s point of view, which is the protagonist and faces difficulties promoting into a new culture and evolving as a person. Examining the intricacies of identity, marriage, and adaptation, this is a gripping account of the cultural and personal changes that an Indian woman in the US went through.
Retelling of Myth through Feminine Lens: An Analysis of Retelling of Mahabharata in The Palace of Illusions by Chitra Banerjee Divakaruni and Karna’s Wife by Kavita Kane
Authors: Viswaraj Devi
Published: September 2024

Post millennium literatures are characterised by their diversity, empowerment and inclusion. Retelling of myth as a method in post-millennium literatures involve adapting and recontextualizing traditional narratives for contemporary audiences. It involves taking traditional myths, legends, or folklore and presenting them in new forms or contexts, adapting them to modern settings, reinterpreting them through different cultural lenses, or incorporating them into original narratives. It may involve reinterpretation and adaptation and often seeks to convey specific messages or insights. The Mahabharata is one of the most revered and influential texts in Indian culture and Hindu mythology. Mahabharata, the magnum opus of Indian Culture, consists of over 100000 slokas and long prose passages. The myths in The Mahabharata are not mere stories, but morals aimed to lead human beings to the right path. Its rich narrative, complex characters, and profound philosophical teachings have captivated audiences for centuries, inspiring countless adaptations and reinterpretations.

Authors: Maheswari D , Ramya C
Published: September 2024

Society and literature have always had a deep and enduring link. It has seen how women’s roles have evolved throughout time, and that development additionally influenced how women are portrayed in literature. Writings from the present day depict not just the oppressed and disenfranchised women but additionally the ‘new women’, who are always attempting to become independent, self-aware individuals. The privileged middle-class environment is portrayed by the author in this book. She still finds the sense of injustice and brutality she encounters in the world upsetting. Her natural incapacity to adjust to her social environment is a handicap. The following feminism-related themes are examined by the researcher in this novel-the necessity of hindrance in life, the impact of childhood trauma on adult personality traits, parental division, and alienation, the impact of childhood being homeless and the ensuing anxiety, distraction, regression to childhood, a state of isolation, and frustration of city life, lack of communication between partners, unpredictable contradictions, as well as brutality in life. Deshpande’s novel The Binding Vine, middle-class Indian women of today, both professional and illiterate, grapple with the challenge of realizing their own identities and reestablishing their familial bonds. The author portrays women’s lives in this book as they are much like in her previous works.

Inequality in Mulk Raj Anand’s Untouchable
Authors: Periyanayaki C
Published: September 2024

Great novelist Mulk Raj Anand has addressed socioeconomic issues in his writing. His passion is portraying contemporary India, complete with its corruption, untouchability, starvation, poverty, superstitions, labor troubles, and economic anxieties. The novel Untouchability focused on the underprivileged segment of Indian society that was deemed “Achhut” untouchable, meaning that upper-class individuals “Swarna Varga” were not allowed to touch them. Through the characters of Bakha, a sweeper, Lakha, the chief of the sweepers in the area, Solini, a Dalit girl, Charat Singh, a charitable man, and many more, the novel accurately portrays society. These figures represent Indian society’s spoilt and collapsing traditional traditions. But the book also shows how society may tolerate cruel, terrible behavior when it comes to the Dalit Vagra, as well as the kindness and compassion displayed by the author’s characters and the optimism that can be seen in the midst of despair thanks to Mahatma Gandhi’s teachings. The narrative also emphasizes how technology was developed and used to elevate humanity through cruel practices like manual rummaging.

Authors: Stadnicka Grażyna , Białek Aleksandra , Kanadys Katarzyna , Ślizień-Kuczapska Ewa , Putowski Lechosław , Pilewska-Kozak Anna
Published: September 2024

Introduction: Stress is described as feelings of worry, unease and mild anxiety. Subjective emotions and mood during pregnancy affect the psychological state of pregnant women. Aim of the work: To investigate the emotional state that characterises women during pregnancy and what determines it. Material and method: The study group consisted of 588 pregnant women. The study was conducted between November 2023 and January 2024 in women’s counselling centres and birthing schools in the Lublin Province. A diagnostic survey method was used, with the author’s survey questionnaire, the General Mood Scale (authors Wojciszke, Baryła) and the Emotions Questionnaire (authors Wojciszke, Baryła). Results of the study: Women between 26 and 35 years of age constituted the largest group (n = 417; 71%; 70.92%). One in five subjects (n = 118; 20.07%) was between 18 and 25 years of age, while pregnant women over 40 years of age accounted for approximately 1% of the subjects (n = 6). The subjects were divided into three groups, depending on the trimester of pregnancy: 1st trimester of pregnancy accounted for 8.33% of the subjects, 2nd trimester of pregnancy 48.64% (n = 286) and 3rd trimester of pregnancy 43.03% (n = 253). Statistical analysis showed no statistically significant differences (p>0.05) in the negative and positive mood scores of women in the different trimesters of pregnancy. High levels of negative emotions were found among women who felt a lack of support from relatives (M = 58) and among women who felt insufficient support from relatives (M = 51). In contrast, low levels of negative emotions were found among subjects who declared that they were coping well on their own (M = 39), as well as those who had high support from their partner/relatives (M = 39). The highest intensity of positive emotions was observed among women who had lost one pregnancy (M = 40), while the rate of positive emotions was slightly lower in subjects who had been pregnant for the first time or had no obstetric failures (M = 38). Conclusions: The stage of pregnancy does not significantly affect women’s mood, but a slight increase in the intensity of positive mood is observed in the 3rd trimester of pregnancy and a higher intensity of negative mood in the 1st trimester of pregnancy. In addition, a higher intensity of negative emotions is observed for women of low material status, less educated, under 25 years of age and living in rural areas. Support from a partner/relative has a significant impact on the emotions felt and expressed during pregnancy. Negative emotions during pregnancy are mainly experienced by women who have lost three or more babies due to miscarriage, premature birth or stillbirth. It seems reasonable to conduct further research to identify stressors in pregnant women, which will allow to individualise professional care for this group of women.

Authors: Balıkçı Derekaya Filiz , Horasan Bestegül
Published: September 2024

In this study total oxidation of methane was studied. The effect of zeolite support type, catalysts components on the characteristic and catalytic properties of the catalysts were determined. For this reason, SAPO34 and Zeolite 13X were used as zeolite support. PdO, CeO2, ZrO2 catalysts components were used as active component and as promoter component. Characteristic properties were determined by using X-Ray Diffraction, N2 Physisorption and Scanning Electron Microscopy analysis. According the characteristic results, to obtain high surface area SAPO34 should be chosen as support. Total methane oxidation catalytic activity studies showed that, like characteristic properties the best results in catalytic activity studies were obtained from SAPO34 zeolite supported catalysts. In this study PdO-ZrO2/SAPO34 catalyst is determined as the most active catalyst for total oxidation of methane. Based on the results, it can be said that the internal interaction between PdO and ZrO2 is better than the internal interaction between PdO and CeO2, and that the PdO and ZrO2 pair is more compatible for methane oxidation in the support structure

The rapid development of the PCR method opens up new opportunities for science and diagnostics. At the same time, the steady increase in the number of studies conducted increases the risk of contamination and, as a consequence, false-positive results. Today there are many ways to solve this problem, but none of them is universal. This paper presents the results of a comparison of the use of disinfectants and special decontamination agents to eliminate contamination of laboratory surfaces with nucleic acid amplification products – PCR amplicons. Study of decontamination activity against short DNA fragments of 117 bp were carried out under conditions that most closely simulate contamination of laboratory surfaces with PCR products. The effectiveness of decontamination was assessed by the residual number of amplicons in swabs from working surfaces. The high efficiency of destruction of amplicons when treating plastic, glass and metal surfaces with special decontamination agents based on metal ions and disinfectants based on oxygen-containing compounds has been shown. At the same time, it has been shown that agents containing a peroxide radical are capable of destroying amplicons mainly in combination with UV irradiation. Based on the results obtained, the feasibility of using metal ion-based decontamination agents for rapid and effective surface treatment in laboratories using nucleic acid amplification methods was demonstrated. Keywords: disinfectants, PCR, amplicons, decontamination.

Published: September 2024

Aiming at issues such as low instantaneous grasping ability, unsatisfactory cutting quality, and proneness to damage of the blades for existing harvesters, by observing the physiological structure and movement characteristics of the ant's mandible and by bionic design theory, a bionic blade was designed to optimize its performance. In this paper, Camponotus was selected as the research object to observe the movement of the right mandibular teeth. It was concluded that the movement of the ant's mandibular teeth was a cutting-sawing motion. A comparative analysis was carried out using the flat blade and the mandibular teeth blade, uncovering that the mandibular teeth movement formed a sliding cut with a variable sliding cutting angle. The mandibular teeth were beneficial for clamping the target and boosting the instantaneous grasping force. The fourth tooth of the mandible was selected as the bionic prototype. from which the contour curve was extracted and analyzed, followed by the design of the bionic blade. Through the finite element method, the influence laws of parameters such as the tooth pitch, structural angle, and blade inclination angle on the stress field and deformation of the bionic blade were analyzed under two force application circumstances: along the inclination direction of the tooth edge and the blade face direction. The results showed that when the applied force was along the tooth edge inclination, the total deformation of the bionic blade initially decreased and then increased with the tooth pitch increase. The maximum equivalent stress of the bionic blade rose gradually with the tooth pitch increase, and the total deformation decreased with the increase of the inclination angle of the tooth. The equivalent stress diminished with the rise in the inclination angle. With the increase of the structural edge angle, the total deformation of the bionic blade rose gradually. When the force was applied along the blade face direction, the deformation and stress values of the blade were significantly lower than those when the force was along the tooth edge inclination. The research findings can offer theoretical references for the design of bionic blades for harvesters.

Relevance. Influenza A virus is characterized by a segmented single-stranded RNA genome. Such organization of the virus genome determines the possibility of reassortment, which can lead to the emergence of new virus variants. The main natural reservoir of most influenza A virus subtypes are wild waterfowl. Seasonal migrations gather waterfowl from all major migration routes to nesting areas near the northern and southern polar circles. This makes intercontinental spread of influenza A viruses possible.
Objective ‒ to conduct molecular genetic monitoring and study the phylogenetic relationships of influenza A virus variants circulating in Antarctica in 2023.
Materials and methods. We studied 84 samples of biological material obtained from birds and marine mammals in April‒May 2023 in coastal areas of Antarctica. For 3 samples, sequencing was performed on the Miseq, Illumina platform and phylogenetic analysis of the obtained nucleotide sequences of the influenza A virus genomes was performed.
Results. The circulation of avian influenza virus in the Antarctic region was confirmed. Heterogeneity of the pool of circulating variants of the influenza A virus (H3N8, H1N1) was revealed. Full-length genomes of the avian influenza virus were sequenced and posted in the GISAID database (EPI_ISL_19032103, 19174530, 19174467).
Conclusion. The study of the genetic diversity of influenza A viruses circulating in the polar regions of the Earth and the identification of the conditions for the emergence of new genetic variants is a relevant task for the development of measures to prevent biological threats.

Published: September 2024

Introduction: Borderline Personality Disorder (BPD) is a frequent and complex condition that leads to significant mortality and psychosocial disability and is associated with numerous comorbidities. Recent international guidelines focus on psychotherapeutic approaches, relegating pharmacotherapy and hospitalization to secondary roles. Objective: To assess the management attitudes of Borderline Personality Disorder (BPD) among psychiatrists in Morocco, and to provide an update on the new therapeutic strategies described in the literature. Methods: This is a descriptive cross-sectional study conducted via an anonymous self-administered online questionnaire completed by psychiatry residents and specialists in Morocco. The findings are then contrasted with the latest recommendations described in the literature. Results: Our study included 86 participants consisting 63 specialists and 23 residents, with years of experience in the field of psychiatry ranging from less than 5 years (31.4%), 5 to 10 years (23.3%), 10 to 20 years (23.3%), to more than 20 years (22.1%). Among these psychiatrists, 97.7% consider the management of patients with BPD to be difficult or very difficult. In our sample, only 39.5% of psychiatrists report adopting psychotherapy as the first therapeutic approach for patients with BPD. Cognitive Behavioral Therapy (CBT) is the most commonly offered (71%), followed by Schema Therapy and Family Therapy (33.7% both). When it comes to pharmacological management: in 54.7% of cases, monotherapy is the standard approach. As a first-line treatment, antidepressants are the most commonly prescribed psychotropic class (69.8%), followed by atypical antipsychotics (44.2%), and then mood stabilizers (34.9%).

Divorce and the resulting conflicts can have a profound impact on the life, development, and psychological health of children, who are essential members of the family. This impact is particularly severe when the child has an existing psychiatric disorder and is exposed to the distressing dynamics between their parents. In some cases, disputes over custody and contact arrangements, as well as attempts by parents to influence the child against the other spouse, can exacerbate the child’s condition. This paper discusses a 16-year-old patient of Franco-Moroccan origin, diagnosed with type I bipolar disorder, who has been under psychiatric care since 2012. The patient has a history of five hospitalizations and numerous manic and depressive episodes. The onset of his symptoms coincided with the emergence of familial conflicts, and his first hospitalization occurred at the time of his parents' divorce. The severity of his psychiatric disorder increased in tandem with escalating parental disputes over his custody and psychiatric care. This case highlights the significant impact of parental conflict and divorce on the progression of psychiatric pathology in children.

Introduction: Local anesthesia has become preferable to general anesthesia for cataract surgery due to improvements in techniques and instrumentation. The advantages of local anesthesia are well known and include more rapid ambulation, the ability to perform the procedure as an outpatient, avoidance of complications of general anesthesia, and quicker surgery. This study aimed to evaluate and compare the efficacy of topical and retrobulbar anesthesia for cataract surgeries. Methods: This was a retrospective observational study and was conducted in the Department of Anaesthesia, analgesia and Intensive Care Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period from July, 2022 to August, 2023. In our study, we included 60 patients who were undergoing cataract surgery. Patients were divided into two groups – Group A (Patients who received topical anesthesia) and Group B (Patients who received retrobulbar anesthesia. Result: The mean age of study patients was 73.4 ± 8.9 and 74.2 ± 7.4 in Groups A and B respectively. The mean Pain score was 0.87 ± 1.41 and 0.74 ± 1.70 in Groups A and B respectively. The most common preoperative risk factor was exfoliation syndrome (40% in group A and 30% in group B). Twenty-eight patients (93%) in the topical anesthesia group and 60% in the retrobulbar anesthesia group reported no pain at all. Conclusion: In conclusion, topical anesthetic, as opposed to retrobulbar anesthesia, offers the surgeon good surgical conditions and comfortable operating circumstances for the patient, even in challenging instances with related ocular comorbidities.

Chordoma is a rare and locally aggressive tumor that arises from the notochordal remnants that corresponds to 1 to 4 % of all malignant bone tumors in the axial skeleton, and has an incidence of 0.1/100000 per year. It consists of a silent and slow-growing mass that requires radical treatment due to its high potential for local and metastatic invasion. It is typically managed with surgery in combination with radiation therapy. The risk of recurrence is very high due to the infiltrating nature of the tumor. A favorable outcome depends on early diagnosis and surgical resection with tumor-free margins. It can arise along the ventromedial aspect of the sacrum, mobile spine, and clivus, with most cases occurring in the sacrum or skull base. We report a case of a 56-years male who complained of pain over his sacral region for the past three years and constipation with no neurological signs. Eighteen months after undergoing large surgery resection for his sacral chordoma with no adjuvant treatment. He was then diagnosed with recurrent sacral chordoma and planned for radiotherapy given the possible complications after surgery.

Climate change-induced (CCI) calamities have immense negative impacts on coastal fishers’ livelihoods by damaging their household and fishery-related assets, which triggers cyclic poverty among them. This study aimed to identify household-level economic penalties due to CCI calamities among the coastal fishers of Bangladesh. A cross-sectional study was conducted among 338 coastal fishers living in 11 coastal districts using a random sampling technique. Males outnumbered females [84.6% vs. 15.4%], with nearly all (99.1%) living below the poverty line. On average, coastal fishers had to struggle against at least three (3.12 ± 1.28) CCI catastrophes with considerable losses per incidence [domestic asset loss: 38318 ± 33071; loss in fisheries: 19236 ± 20486] within the past five years. CCI incidences such as severity of disaster, longevity of disaster, winter-cold shock, and water flow were significantly associated with domestic asset loss [95% C.I., p<0.05]. Similarly, severity of disaster, winter-cold shock, water flow, and sea waves during storms were also significantly associated with the impoverished status of coastal fishers in Bangladesh. Climate-resilient coastal management and livelihood improvement policies implemented by the relevant authorities could reduce impending economic penalties for coastal fishing communities.
İlliberalleşen Demokrasilerde Siyasal Katılımın Önündeki Güçlükler

Tarih boyunca en iyi yönetimi nedir ve nasıl olmalıdır sorunsalına cevap aranmış ve en ideal yönetim olarak demokrasiler genel kabul görmüştür. Temel olarak bireyi ve haklarını esas alan demokrasi anlayışı, bireyin yönetime doğrudan ya da dolaylı şekilde katılmasını sağlamaktadır. Ancak demokrasinin gelişim süreci ve demokrasiye yönelik eleştiriler, liberal demokrasi gibi farklı demokrasi türlerini ortaya çıkarmıştır. Demokrasinin en yaygın türlerinin başında gelen liberal demokrasi modelinde, genel olarak sınırlı bir devlet anlayışı benimsenmekte ve özgürlükçü, çoğulcu, katılımcı gibi temel ilke ve düşüncelere önem verilmektedir. Bu demokrasi modelinde, bireyler siyasal alana doğru itilmekte ve isteyerek ya da istemeyerek siyasal katılım meydana gelmektedir. Siyaset biliminin en önemli kavramlarından biri olarak karşımıza çıkan siyasal katılım, demokrasinin başarılı bir şekilde uygulanması açısından da son derece önem taşımaktadır. Ancak son yıllarda birçok ülkede demokrasilerin illiberalleştiği (otoriterleştiği) ve dolayısıyla siyasal katılım konusunda önemli sorunlar yaşandığı görülmektedir. Çalışmanın amacı illiberalleşen demokrasilerde siyasal katılım açısından yaşanan güçlüklerin ele alınmasıdır.
