Published: May 2024

Network neuroscience is an interdisciplinary field, which can be used to understand the brain by examining the connections between its constituent elements. In recent years, the application of network neuroscience approaches to study the intricate nature of the structural and functional relationships within the human brain has yielded unique insights into its organization. In this review, we begin by defining network neuroscience and providing an overview of the common metrics that describe the topology of human structural and functional brain networks. We then present a detailed overview of a limited but growing body of literature that leverages network neuroscience metrics to demonstrate the impact of mindfulness meditation on modulating the fundamental structural and functional network properties of segregation, integration, and influence. Although preliminary, results across studies suggest that mindfulness meditation results in a shift in connector hubs, such as the anterior cingulate cortex, the thalamus, and the mid-insula. Although there is mixed evidence regarding the impact of mindfulness training on global metrics of connectivity, the default mode network exhibits reduced intra-connectivity following mindfulness training. Our review also underscores essential directions for future research, including a more comprehensive examination of mindfulness training and its potential to influence structural and functional connections at the nodal, network, and whole-brain levels. Furthermore, we emphasize the importance of open science, adoption of rigorous study designs to improve the internal validity of studies, and the inclusion of diverse samples in neuroimaging studies to comprehensively characterize the impact of mindfulness on brain organization.

Authors: K Vidya , V Vishnupriya , R.K Radha , S Prathima
Published: May 2024

Background: Male infertility is on the rise globally. It contributes to about 40-50% of all infertility cases. Semen analysis forms the basic investigation for the assessment of male factors of infertility, but it has its pitfalls. Literature review has suggested newer parameters of semen analysis such as sperm quality, which can have a significant role in the outcome of pregnancy. This study aims to assess sperm DNA integrity and calculate the DNA fragmentation index, which is a measure of the quality of sperm, thereby highlighting the need for assessment of sperm quality along with sperm quantity.
Materials and methods: 459 cases underwent routine semen analysis along with the DNA fragmentation index. Sperm quality was assessed using Modified Acidic Aniline blue staining. The statistical analysis was done using SPSS using a t-test and Chi-square test. Results: Advancing age did not affect all parameters. The DNA fragmentation index showed no effect on sperm count. Unpaired t-test correlation showed a negative correlation between DNA fragmentation index and sperm motility, viability, and morphology.
Conclusions: This study highlights the need for increasing awareness about the male-factor of infertility with special reference to the quality along with the routine quantitative assessment of sperm. A conventional semen analysis along with a DNA fragmentation index assessment can help the clinician put forward the choice of artificial reproductive techniques for the couple and provide an accurate success rate of treatment.

Authors: Nilam More  , Joshi Amita , Jumnake Snehal , Gulhane Pallavi
Published: May 2024

Background: Eosinophils are inflammatory cells that can infiltrate several organs playing a major role in causing tissue damage and organ dysfunction. This study was conducted to establish the baseline eosinophil count in normal states and to correlate mucosal eosinophil count with abnormalities of the oesophagus and stomach.
Materials and methods: A retrospective observational study was conducted at the surgical pathology department of a tertiary care hospital in Mumbai. A total of 124 biopsies were studied. Oesophageal and stomach biopsies with some pathology including oesophagitis, gastritis, ulcer, nonspecific inflammation, etc, were considered abnormal.
Results: Out of 124 biopsies, 36 (29.03%) were normal, while 88 (70.97%) were abnormal. Eosinophilic gastrointestinal disease had male predilection. In abnormal oesophageal biopsies, 16 (88.9%) of 18 oesophageal biopsies had an eosinophil count in the 0-5 eos/HPF band, whereas 50 (71.4%) of 70 abnormal stomach biopsies had eosinophils in the 0-5 eos/HPF band. The eosinophil count reported was 24/HPF in eosinophilic oesophagitis.
Conclusions: Almost all normal oesophageal biopsies (90.9%) and stomach biopsies (100%) showed eosinophil count as 0 eos/HPF and <10/HPF respectively. So if one finds eosinophils in a biopsy sample, one needs to look for other specific pathology.

Published: May 2024

Plasma cell leukaemia is the rarest yet most aggressive plasma cell disorder characterized by a malignant proliferation of plasma cells in the blood and bone marrow. Leukaemia cutis includes cutaneous manifestation of any type of leukaemia, and is defined as skin infiltration by malignant leukocytes or their precursors, resulting in clinically detectable cutaneous lesions. Plasma cell leukaemia cutis is a rare clinical presentation with an adverse prognosis which makes the index case an unusual entity. We hereby report a case of primary Plasma cell leukaemia, who presented with multiple cutaneous scalp nodules. Fine needle aspiration cytology performed on these scalp nodules revealed cellular smears exhibiting mature and immature plasma cells dispersed singly and arranged in small clusters. The total leukocyte count was 25,800/cu mm, with differential count of 18% polymorphonuclear leukocytes, 20% lymphocytes and 62% abnormal plasmacytoid cells. The diagnosis of primary PCL with cutaneous involvement was subsequently rendered through histology and immunophenotyping.

Authors: Das Chhanda , Mukhopadhyay Madhumita , Mukhopadhyay Satinath , Hazra Avijit
Published: May 2024

Background: Pituitary Adenoma, a neoplastic proliferation of anterior pituitary hormone producing cells, is mainly considered benign but some are clinically aggressive and recurrent and very rarely malignant. From recent advances in pathological and molecular study, there is a continuous search for numerous prognostic biomarkers, to analyze better tumor behavior and prediction of response to treatment and recurrences. This study was conducted to see the epidemiological spectrum of pituitary tumors and to evaluate the correlation of TOPOISOMERASE IIα (Topo 2A), and Ki-67 biomarker with recurrence, aggressiveness, hormone subtype, radiological invasiveness, and prognostic grade of pituitary tumors.
Materials and methods:This was a prospective study with a total of 54 cases. We studied the clinical behavior, radiology, histopathological findings, and immunohistochemistry with Ki-67, Topoisomerase IIα, over 3 years at a tertiary care center.
Results:When comparing Ki-67 expression with aggressiveness, a high degree of statistical significance was found (Mann -Whitney U Test, p-value <0.001 ). All of our aggressive tumors (8/54) had a Ki-67 level of≥3% while most of the nonaggressive tumors (46/54) had a Ki-67 level of <3%. When comparing Topo 2A expression with recurrence, a high degree of statistical significance was found (Mann Whitney U test, P value <0.001). Most of the recurrent tumor (11/15) had Topo 2A index of 1 % or more.
Conclusions: The benign, aggressive, recurrence, or malignant nature of PA can be effectively predicted with the help of immunohistochemistry such as TOPO 2A and  Ki67, thereby guiding better patient management.

Authors: Balaiya Dhivya , Chellam Annadurai Anitha , Subbiah Rajendran Jayakarthiga
Published: May 2024

Background: The clinical outcome of breast carcinoma varies in each individual due to its molecular heterogeneity. There is a rising interest in whether the associated ductal carcinoma in-situ in invasive ductal carcinoma of breast affects the prognosis and overall survival of the patient. This study evaluates the difference in clinico-pathological and immunohistochemical prognostic factors between invasive ductal carcinoma with associated in-situ component, and invasive ductal carcinoma alone.
Materials and Methods: The study was conducted at a tertiary care hospital in South Tamilnadu, India. Two study groups were categorized based on the presence/absence of in-situ component in invasive ductal carcinoma of breast. Clinico-pathological variables and immunohistochemistry [Estrogen receptor (ER), Progesterone receptor (PR), HER2/neu and ki67] findings were compared between the two groups and statistical analysis was performed.
Results: There were 25 cases in each group. A significant statistical difference in tumor size was observed between invasive ductal carcinoma associated with in-situ component (mean-3.6cm) and without in-situ component (mean-5.0cm). A higher proliferative index (60%) was seen in invasive ductal carcinoma alone. There was no difference in the expression of Her2neu between the two groups. A proportionate increase in premenopausal population (60%) and hormone receptor positivity (ER, PR) was observed in invasive ductal carcinoma associated with in-situ component.
Conclusions: Invasive ductal carcinoma associated with ductal carcinoma in-situ shows a less aggressive behaviour compared to invasive carcinoma alone. Further studies of a larger scale need to be done which might help in identifying the subgroup for targeted therapy.

Authors: Alam Fahad , Chaurasiya Anand Kumar , Akhtar Md. Kalim , Shrestha Brijesh
Published: May 2024

Background: Ovarian tumors are a common form of neoplasm in women. Early diagnosis and management of ovarian tumors is a major problem in a developing country like Nepal, due to lack of awareness and limited facility for investigations in all parts of Nepal. Usually, the malignant ovarian neoplasms will have already advanced too far by the time they are detected. This study was proposed to identify the spectrum of ovarian tumors and their clinicopathological features.
Materials and methods: This was a hospital-based cross-sectional descriptive study over a period of two years. Ovarian tissue with clinical notes sent to the histopathology department in 10% formalin was received. The specimens were subjected to critical gross as well as histopathological study. Routine paraffin sections with Hematoxylin & Eosin staining were used. The clinical as well as histological findings were compiled on proforma and then subjected to analysis. This was a descriptive study and data were tabulated and analyzed using the Statistical Package for Social Sciences (SPSS) version 21.0
Results: A total of 50 patients were included in the study with the age range from 15 years to 63 years. Maximum patients were from age group 41-50 years (36%). In the present study, abdominal pain (62%) was the most common presenting complaint followed by mass per abdomen (20%) and irregular periods (10%). The majority of the ovarian tumors belonged to benign tumors (82%) followed by malignant tumors (12%). As per WHO classification, surface epithelium tumors were found to be the most common variety (84%), followed by germ cell tumors (10%). Among the various known subtypes of ovarian tumors, serous cystadenoma (48%) was found to be the most common subtype followed by mucinous cystadenoma (20%).
Conclusions: Benign ovarian tumors are more common than malignant or borderline tumors. Among the histopathological subtypes of ovarian tumors, surface epithelial tumors are the most common type. Differentiation between benign and malignant tumors is important to assure proper management and recovery. Similar studies with greater sample size are advisable in the future.
History and contestation: On teaching Diversity and Self-Determination in International Law
Authors: Taha Mai
Published: May 2024

In this article, I share some thoughts about the afterlives of Karen Knop’s work within the space of the classroom, a space she inhabited with humility, interest, and care. I am approaching this as an ode to her, not only as a brilliant scholar but also as a wonderful teacher, supervisor, and mentor. Every year, I teach ‘The Canon of Self-Determination,’ a chapter from Knop’s 2002 book Diversity and Self-Determination in International Law. Through this chapter, students learn about the trial as a space of political contestation and of rupture and continuity and as a space that opens a conversation with the past as it is constantly shaped and reshaped by the present. Knop was concerned with the question of decolonization in international law and how, through the courtroom, anti-colonial lawyers put international law itself on trial. In this article, I want to think about the enduring significance of teaching this text every year.
On lizard pumps and the self-determination of Karen Knop
Authors: Sands Philippe
Published: May 2024

Karen Knop had a myriad of human and intellectual qualities, not least a remarkable ability to straddle a range of different worlds. She was as comfortable delving into legal theory as she was conversing with judges of the Supreme Court of Canada or the International Court of Justice. Her ability to meld the personal and the scholarly was reflected in her work and in the essence of her being, offering those who engaged with her scholarship the courage to mix the two in their own ways. Her book, Diversity and Self-Determination in International Law, laid bare the threads of unstated biases and instincts that influenced scholarship and rulings on self-determination. Its call to examine issues of diversity, marginalization, and gender impacted scholarship as well as the strategic and substantive choices of some who represented Mauritius in the Chagos proceedings before the International Court of Justice. This, it might be said, contributed to the life of the Court in its advisory opinion.

HRIGORY VASHCHENKO AND OUR TIME, OR IS THE UKRAINIAN HISTORICAL AND EDUCATIONAL HERITAGE RELEVANT IN THE CIRCUMSTANCES OF MARTIAL LAW?
Authors: Dichek Natalia
Published: May 2024

An attempt has been made to prove that in the context of the martial law situation, which has been dragging on in Ukraine for the third year as a result of Russia’s aggressive actions, the thoughts the outstanding educator Hrigory Vashchenko (1878 1967), have become in demand like never before during the period of the sovereign existence of our state. He created nationally oriented concept of educating Ukrainian patriots in the middle of the XXth cen., but they are of topical interest. The educational instructions he formulated, addressed to Ukrainian youth and their educators, holistically cover the process of formation of national consciousness and patriotism, from birth to adulthood.Based on the textual analysis of G. Vashchenko’s works and their contextual understanding, the main tasks of national patriotic education are highlighted, effectively embodied in the education of generations of Ukrainian emigrant youth, starting from the mid twentieth century up to this day. According to the purpose of the article, for updating, the following conceptual G. Vashchenko’s provisions are picked out: preservation and promotion of the native language and national culture, which determine Ukrainian spirituality and are spiritual factors in the build state; transmission of historical knowledge about the heroic path of the struggle of Ukrainians for their independence, which, on a psycho emotional, conscious level, firstly, influences the national self identification of young people, their historical memory, and secondly, charges young Ukrainians with examples of the heroic deeds of their ancestors, motivates the expediency of not only forming strong nationally oriented beliefs, but also exercising physical and volitional training to defend the independence of their native land.

The red calliandra is a fuel wood crops that gave benefit for people. Recently, it is getting wide attention due to its important use as biofuel in industrial scale. The massive propagation is needed to meet industrial needs. Beside the use of conventional seedling production technique, the use of tissue culture for mass propagation is one of the alternatives to address this problem. This research was conducted to develop standard protocol for micropropagation of red calliandra through tissue culture. Here, the first step for that purpose was reported. The MS medium was used for basal media treatment. The seed source was stored for eight months under 5oC. This research was carried out in two stages i.e. 1) seed germination test and 2) shoot initiation and multiplication treatment. Each stage was arranged in experimental method. The result showed that seed were pre-treated with warm water (40oC) gave 62.5% germination under red light when compared to control (37.5%, pre-treated with water at 25oC under white light) three days after planting. Conversely, there is no striking differences of germinated seed percentages between light treatment at 25oC. Furthermore, it was found that addition of 2 mg/L BAP gave better result in shoot initiation and number of shoots formed from nodal explants after four weeks in treatment media. These results indicated that mass propagation of red calliandra can be done through tissue culture where multiplication stage is one of the important steps to produce multiple shoots only from single nodal explant.

Published: May 2024

Based on the results of observations that have been carried out in several high schools in Pekanbaru, it can be concluded that it is very necessary to develop teaching materials in the form of E-modules because teachers only use textbooks and LKPD during the teaching and learning process, teachers have never used E-modules during learning. And teachers do not use learning resources that can support students' critical thinking skills. Students experience difficulty in providing arguments when asked for written explanations to solve problems, and students are unable to analyze and synthesize problems. The aim of this study was to determine the effectiveness and efficiency of the electronic components of the immune system of PBMP. It is hoped that this study can help teachers to choose new learning materials as an alternative to support learning during the 4.0 revolution, and to provide learning experiences using electronic components. PBMP (problem-based empowerment) and encourage learning. Students will study the resources of the immune system so that students can think critically to develop. The efficiency test results are classified as very efficient which can be seen in the average relevance of 96.08% in the most effective category.

This study aims to determine the morphological and physiological properties of Phosphate Solubilizing Microbes (MPF) and Azotobacter. The method used was to test morphological properties using gram staining and physiological properties tests using biochemical tests based on cell activity by looking at the interaction of bacterial metabolism with the test reagent media. Data analysis examined the reaction to the isolated morphological and physiological test media. The results showed that based on the morphological observations of the MPF, the colonies showed a slightly milky white color, round, convex, slimy shape, 1-2 mm in diameter and flattened, and Gram-positive. Azotobacter shows the characteristics of transparent color, convex, flat edges, slightly slimy, an average diameter of 1 mm, and is Gram-negative; whereas based on the results of physiological test observations for catalase and oxidation tests, the characteristic of MPF and Azotobacter, each showed a positive (+) effect, as seen from the formation of bubbles in the test results. Tests for motility and O2 requirements show that both bacteria are motile, mobile and aerobic or require oxygen for growth. The observations of resistance in the pH range showed that Azotobacter was more resistant to extreme acid-base pH with a pH range of 3-9, while MPF could only survive in a pH range of 5-9. Tests of glucose and sucrose fermentation showed that MPF did not form gas bubbles (-) and no color change(-). At the same time, Azotobacter showed the formation of gas bubbles (+) but no color change (-).

The Nadsonian motif in the “fi rst poem” by I. A. Bunin and M. Gorky
Authors: Uryupin I. S.
Published: May 2024

The article examines the phenomenon of the “first poem” in the works of I. A. Bunin
and M. Gorky in the theoretical, historical and literary aspects and reveals the correlation
of the concepts of the “literary debut” and “first poem,” between which there is no semantic
identity. Literary debut refers to a work created in accordance with certain ideological and
aesthetic ideas and orientations of the author, which the he deliberately updates during his
entry into the history of literature. I. A. Bunin considered the poem “The Village Beggar” his
literary debut, which continued the classic traditions of Russian democratic lyrics, while in
fact the first published poem “Over the Grave of S. Ya. Nadson,” which is a proto-symbolist
text, the poet himself, who declared distrust of modernist art, left on the periphery of his
work. The article analyzes the figurative genesis of the “first” poems of I. A. Bunin, in
which, with all their stylistic and problematic-thematic differences, the influence of S. Ya.
Nadson was reflected. Nadsonian pathos was also perceived by M. Gorky, whose first poem –
“Goodbye!” – contains a Nadsonian complex of motifs and plot devices. The neorealistic
attitudes of I. A. Bunin and the neoromantic strategies of M. Gorky, with all their differences

Authors: Larina A. V.
Published: May 2024

The value-semantic basis of high school
students’ verbal and cogitative activity formation
Authors: Ariyan M. A. , Gorobinskaya N. V.
Published: May 2024

The present article deals with the problem of forming the semantic basis of
language education. Human consciousness is inextricably linked with the meanings the
bearer of which is the text. The article notes the importance of the value-semantic principle in
the educational process and determines the conditions for the formation of the value-semantic
sphere of the individual. The article substantiates the need for the semantic integrity of the
content of language education, which can be ensured, in particular, through the formation
and strengthening of interdisciplinary links. It is argued that texts containing value-semantic
reference points should be an important component of the content of language education. The
special significance of socially-pointed speech situations is noted, which creates conditions
for the formation of a high school student’s social and moral position. Examples of tasks
are proposed that allow making learning personally significant, aimed not only at mastering
knowledge, but also at gaining meanings as elements of personal experience.
