Determination of Barr bodies in Transgender Patients in India – A comparative study
Authors: Lakshmi Aishwarya , James Amritha , Annasamy Rameshkumar , Krishnan Rajkumar
Published: December 2023

Sex determination in forensic medicine is considered one of the first and foremost steps in personal identification. The need for identifying the exact sex of the individual arises when deciding whether a person can exercise certain civil rights reserved for one particular sex, for competing in sex-specific athletic and sports events, legitimacy, divorce, paternity disputes and also to some criminal offenses. Nuclear sexing by Barr body examination can be done using buccal smears to establish the sex of the individual when routine methods fail to disclose the exact gender of the individual.

Aim:

To determine and compare the Barr bodies present in exfoliated buccal epithelial cells in males, females and transgender populations using light and fluorescence microscopy.

Materials and Methods:

A total of 90 patients were recruited for the study. Group I consisted of 30 female patients. Group II consisted of 30 male patients and group III consisted of 30 transgender patients. The buccal mucosa was then scraped using a wooden spatula and the cells obtained were fixed in 95% ethanol. Two smears per individual were made and stained. One smear was stained with papanicolaou (PAP) stain and the other with Acridine orange and viewed under light microscopy and fluorescent microscopy, respectively.

Results:

When PAP stained slides were examined, the percentage of Barr-bodies in females ranged from 3% to 5% and in males it was 0% and in transgenders, it ranged from 0% to 5%. In Acridine orange stained smears, the percentage of Barr bodies in females ranged from 1% to 3% and in males it was 0% and in transgenders, it was 0%. Kruskal–Wallis test to study the relation of Barr body percentage in females, males and transgender subjects demonstrated significant differences between the groups (P < 0.001). Wilcoxon signed rank test was done for pairwise comparison, which showed that the distribution of percentage of positive cells in females are statistically significant from males and transgenders (P < 0. 001).

Conclusion:

Nuclear sexing using Barr bodies offers a simple yet effective method for determining the sex of transgender patients which could help them in understanding their gender identity better and diagnose any underlying chromosomal aberration.
Corpus alienum (foreign body) embedded in the oral cavity of children: An agony of parents and diagnostic dilemma among clinicians
Authors: Ray Jay G. , Kashyap Nikita , Ghose Sandip , Das Monalisa
Published: December 2023

Aspiration or ingestion of foreign bodies by children is a common problem globally. Corpus alienum or foreign bodies, embedded in the palate or other areas of the oral cavity, are unusual findings that can occasionally be muddled with other oral lesions. Studies reveal that the majority of cases occur in children, wherein 50% of the children lack a proper history. Since infants or very young children fail to provide proper history and are extremely scared of repeated oral examination clinical diagnosis is all the more difficult. The risks of respiratory obstruction, mucosal tear, nasopharyngeal inflammation, and gastrointestinal bleeding make these non-invasive foreign bodies potentially fatal.
Role of proliferative markers in assessing recurrences in surgical margins of oral squamous cell carcinoma: A systematic review
Authors: Gawande Madhuri , Khan Samiha , Sharma Nidhi , Hande Alka , Patil Swati
Published: December 2023

The primary goal of this systematic analysis is to determine the predictive significance of proliferative markers in surgical margins of patients with oral squamous cell carcinoma (OSCC). A thorough literature search was done on databases like MEDLINE/Pub-Med, Cochrane and Scopus libraries for similar studies until December 2022. All the relevant original research studies (retrospective and prospective) published in the literature assessing the predictive value of proliferative markers in surgical margins in OSCC were included. Seventeen studies with 1159 patients were included. The research included here used p53, p44/p42, proliferating cell nuclear antigen (PCNA), epidermal growth factor receptor (EGFR), Ki-67, Bcl2, Nibrin, AgNORs, Cyclin B1, Cornulin, ISG 15antibodies, MCM3 in OSCC. Four studies were done on oral premalignant lesions and OSCC. Among these studies, Ki-67 was the most accurate, followed by p53 (75%) and AgNORs, while PCNA had the least accuracy. To minimize the risk of bias panel of antibodies was suggested in most studies. For interobserver variability, analysis of variance and Chi-square test were used in most studies. The chance of recurrence rate was calculated using a log-rank test and a Kaplan–Meier curve. The significance of proliferative markers in surgical margins of OSCC has been emphasized in the present review. Future research should focus on selecting antibodies, preferably a panel, with a large sample size and extended follow-up.

Authors: Harti Shreya A. , Adarsha M. S. , Meena N. , Priya N. S. , Vijayalakshmi L. , Airsang Akshata J.
Published: December 2023

Background:

The success of the root-end procedure depends on the regeneration of the functional periodontal attachment system, including the cementum on the resected root-end surface, periodontal ligament (PDL), and alveolar bone. As root end filling materials remain in close contact with live periapical tissues, they may influence the endodontic treatment outcome.

Aim:

To assess and compare the cytotoxicity and genotoxicity of three root repair materials, mineral trioxide aggregate (MTA), endosequence, and geristore in human-cultured periodontal ligament fibroblasts.

Materials and Methods:

Cultured human periodontal ligament fibroblasts of the third passage were used in the study. They were placed in contact with the root repair materials. The cytotoxic effect on PDL fibroblasts was determined by (3-(4,5-dimethylthiazol-2-yl)-2,5-tetrazolium bromide) assay after 24 hours and 48 hours intervals. Cell viability was determined using an inverted phase contrast microscope. The genotoxic effect on the periodontal fibroblast cells was determined by comet assay using imaging software.

Statistical Analysis Used:

Data were analyzed using Tukey’s multiple comparison test and Dunnett’s multiple test.

Results:

All the test materials showed higher cytotoxicity and genotoxicity at the 48th hour interval with a statistically significant difference from the control group (P < 0.05). MTA was shown to be least cytotoxic and genotoxic to PDL fibroblasts, followed by endosequence root repair material and geristore at 24 hour and 48 hour intervals.

Conclusion:

The cytotoxicity and genotoxicity of MTA were the least compared to endosequence and geristore on human-cultured PDL fibroblasts.
Langerhans cell expression in oral submucous fibrosis: An immunohistochemical analysis
Authors: Shafi Shugufta , Anjum Rubeena , Kaur Mandeep , Khajuria Nidhi
Published: December 2023

Introduction:

Langerhans cells (LCs) are dendritic cells (DCs) of the epithelium which play a role in an array of oral lesions from gingivitis to oral cancer. Oral submucous fibrosis (OSMF), a potentially malignant disorder (PMD), is an insidious chronic disease with juxta-epithelial inflammatory changes leading to fibrosis. LCs may play a part in the ongoing inflammatory dysregulation of OSMF.

Objective:

The study was aimed at elucidating the distribution of LCs in varying grades of OSMF.

Materials and Methods:

A retrospective study using 18 cases of OSMF, graded using haematoxylin and eosin (H&E)-stained section. Immunohistochemistry was performed using polyclonal anti-CD1a antibodies to identify LCs in six cases of normal tissue and 18 samples of OSMF. The distribution of LCs among the various grades and normal mucosa analysed using Student’s t-test.

Results:

LC population in the OSMF was significantly higher when compared to the normal epithelium (p < 0.001). Within the grades, the advanced stage had more LCs than the other stages.

Conclusion:

The increase in LCs might indicate the role of antigenic exposure in turn leading to cell-mediated immunity in OSMF. Thus, the fibrosis in OSMF might have a direct link to LCs.

Authors: Penubarthi Sravanthi , Vatte Vishwak Reddy , Kandrakonda Srinivas , Kamlur Abdullah , Kondapalli Spandana
Published: December 2023

Background:

The COVID-19 pandemic had a significant effect not only on physical health but also on one’s psychological health. Global research reveals that one-third of those affected with COVID-19 experience sequelae of psychiatric symptoms, commonly seen as depression, anxiety, and posttraumatic stress disorder. No clear data exist from India on aggression in COVID-19-infected patients during the postillness phase. Hence, we aimed to assess the prevalence of aggression and personality factors associated with aggression in post-COVID individuals.

Materials and Methods:

This study was conducted in a tertiary institute in South India. One hundred and thirty-four patients, inpatients and outpatients, who recovered from COVID-19 were recruited based on purposive sampling. The data from patients were collected using semi-structured proforma with 59 questions on domains such as sociodemographic profile with clinical parameters, occupational factors, aggression, and personality profile. Standardized rating scales such as the Brief Aggression Questionnaire and Modified Overt Aggression Scale were used to assess aggression, while the Big Five Inventory-10 was used to assess personality profile.

Results:

About 17.9% of the study population had positive scores in one or more of the six components of aggression. Those with aggression had a significantly longer duration recovery period when compared to nonaggressive individuals (P < 0.001). Those with aggression had significantly lower mean scores of agreeableness when compared to the other group (P = 0.01).

Conclusion:

With the fourth wave of COVID-19 on the horizon, psychological issues as a part of COVID sequelae need to be acknowledged. Clinicians should emphasize liaison with psychiatrists during follow-up of COVID-19 patients, to screen for any psychiatric symptoms postillness, thereby enhancing the chances of early detection and management.

Authors: Kuchibhotla Ravikanth , Mohan Deepa , Singisetti Srinivas , Khatoon Murshida , Nukala Srikrishna
Published: December 2023

Background:

Mobile phone plays a vital role in the era of tremendous technological evolution. Despite its advantages, several psychological, behavioral, and physiological problems are associated with its use. The phenomenon of feeling anxious, agitated, and nervous when the mobile phone is not accessible is termed “nomophobia.” Different parenting styles affect nomophobia levels irrespective of gender, education, and income.

Aim:

The aim of this study was to examine the relationship between nomophobia, perceived parenting styles, and psychological distress among college students.

Methodology:

A cross-sectional observational study was done for a sample of 305 students, comprising 108 males and 195 females between the ages of 17–28 years. Correlation and between-group analysis were used.

Results:

Nomophobia was significantly correlated with permissive and authoritarian parenting styles. In contrast, it was not related to authoritative parenting styles. Nomophobia was also significantly associated with psychological distress, anxiety and depression, and social dysfunction.

Conclusion:

Nomophobia correlates with permissive and authoritarian parenting styles, and also psychological issues such as depression and anxiety.
Psychiatric comorbidities in patients with conversion disorder – A longitudinal study
Authors: Sharma Shruti , Halder Ankit , Kumar Kunal , Shahani Roma , Ravindran Navna Panchami , Kulkarni Yogesh , Nagda Parth
Published: December 2023

Background:

The word conversion refers to the substitution of a somatic symptom for a repressed idea. The conversion disorder indicates the absence of organic disease or disproportionately small disease compared with the complaint.

Methodology:

Ninety-six patients of conversion were screened for psychiatric comorbidities and followed up for a period of 6 months.

Results:

There was significant number of different psychiatric illnesses among the patients and positive correlation also with duration of illness in subsequent follow-ups.

Conclusion:

Our study highlights the significantly high prevalence of psychiatric comorbidities in patients of conversion disorder in first and follow-up visits with major depressive disorder being the most common one. The propensity to wait for comorbid psychiatric symptoms in conversion disorder to become florid might be unproductive. Early intervention can forestall progression into potentially chronic psychiatric illness.

The stalwart - Carl gustav jung
Authors: Das Jigisha
Published: December 2023

Carl Gustav Jung was a Swiss psychiatrist who pioneered in analytical psychology. His fundamental work on the unconscious human mind, association tests, archetypes, anima and animus, the self, the persona, introverted, extroverted, synchronicity, psyche, complexes, and individuation has an influential impact on psychology, for which he became the father of analytical psychology also known as Jungian psychology. His works in literature, art, philosophy, religion, and spirituality are inspirational. In World War I, he worked under Eugen Bleuler as a psychiatrist at Zurich University. He was a close associate of Sigmund Freud but it did not last long. “Psychology of the Unconscious” is one of his exceptional works.

En el contexto de la exclusión del mercado de trabajo y de los profundos efectos en la subjetividad de los trabajadores/as en Chile, se observa la emergencia de nuevas formas de trabajo autogestionado vinculadas a los movimientos sociales y a las nuevas expresiones de la economía popular. Este artículo presenta los resultados de una cartografía orientada a conocer el perfil de estas organizaciones laborales emergentes en las ciudades de Santiago y Concepción caracterizadas por la vinculación del mundo del trabajo y la reproducción de la vida con el quehacer social y político. La horizontalidad, la opción por la autogestión, la rotación de labores, el cuestionamiento a la división sexual del trabajo, la progresiva colectivización de la propiedad, la des-elitización del consumo de calidad, la relevancia de la comunidad, la mantención de los roles patriarcales de cuidado, son algunas de las características que definen a estas organizaciones laborales de nuevo tipo.
Leyes, parcelaciones y colonias agrícolas: mecanismos de regulación en los procesos de colonización. Colombia y Chile (1920-1950)
Authors: Henao-Holguín Diana , Pinto-Vallejos Julio
Published: December 2023

El artículo analiza los mecanismos de intervención estatal en materia de colonización hacia las zonas de frontera agrícola interna en dos países: Colombia y Chile. Este estudio preliminar propone que, con el fin de apaciguar la agitación rural, ambos estados instalaron políticas de colonización a través de leyes que buscaban regular las relaciones entre el estado y los particulares; y, paralelamente, establecieron colonias agrícolas y parcelaron grandes propiedades. Para el análisis se recurrió principalmente a las publicaciones oficiales de los Ministerios de Industrias, Agricultura y de la Economía Nacional, para el caso de Colombia. Para el caso de Chile se revisaron las memorias de la Caja de Colonización Agrícola y algunas tesis de ciencias jurídicas que analizan la conformación del ministerio de Tierras y Colonización. En ambos casos se revisó la legislación promulgada en materia de ocupación de tierras fiscales.
The March 2023 UAS-based high-resolution Digital Surface Model and orthomosaic of the NE flank of Stromboli volcano (Sicily, Italy)
Authors: Nannipieri Luca , Bevilacqua Andrea , Di Traglia Federico , Favalli Massimiliano , Fornaciai Alessandro
Published: December 2023

Stromboli is a volcanic island in a persistent state of activity, located in the Tyrrhenian Sea off the northern coast of Sicily. During the night of 25 and 26 May 2022, a massive human-caused wildfire destroyed most of the vegetation cover on the NE flank of the island, just above the main village. On 12 August 2022, a particularly heavy rainfall event remobilized the loose volcaniclastic deposits that covered the burned volcanic flank, no longer protected by the vegetation. This event triggered several debris flows that were channeled by the roads and flooded several streets and buildings, causing severe damage to the village. In late-March 2023, just before the large spring vegetation growth, we conducted an Unmanned Aerial System (UAS) photogrammetric campaign over a sector of the NE flank of Stromboli Island, to acquire data on an area massively affected by the wildfire first and by the debris flows later. Here we present and share with the scientific community and civil authorities the results of this UAS campaign, which consists of a 1.4 km2 wide 10 cm-resolution Digital Surface Model (DSM) and 1.6 cm-resolution orthomosaic. These data clearly show the dramatic consequences of the 2022 tragic events at Stromboli. We also produced an elevation difference map by comparing the 2023 DSM here generated and the 2012 LiDAR DEM to provide a first overview of the thickness of the deposits that were removed from the Stromboli NE flank.

Published: December 2023

A floristic study of the plateau at the foot of the Promina Mountain, located between the rivers Krka and Čikola, was conducted in the period 2019-2021. On an area covered largely by sub-Mediterranean dry grasslands and scrubs 275 vascular plant taxa were recorded. Recorded taxa belong to 60 families, among which Fabaceae (14.91%), Poaceae (10.91%) and Asteraceae s. str. (8.00%) are the most abundant. Life-form analysis indicates the dominance of hemicryptophytes (44.73%) and therophytes (21.09%), and as for chorology, there is a domination of South-European (32.73%) and Mediterranean (29.45%) floral element. Only two invasive alien species, Ailanthus altissima and Robinia pseudoacacia were recorded. There are 15 endemic and 26 strictly protected taxa, while 19 taxa are included on the Croatian Red List. Results of the floristic analysis reflect the climate conditions and phytogeographical position of the studied area as well as the history of land use.

Authors: Doboš Marko
Published: December 2023

Four hybrid taxa, previously rarely, or now for the first time recorded in Croatia, observed during the spring of 2020 and 2022 on Mt. Papuk, are presented. A hybrid of Primula vulgaris Huds. and P. veris L. called P. × polyantha Mill. is known as an ornamental plant, which comes in a whole palette of colors, but the occurrence of spontaneous hybrids that occur in nature in Croatia has been discussed in print only once, by Degen in 1937. Ophrys × hybrida Pokorny ex Rchb. f. is a cross between O. sphegodes Mill.and O. insectifera L., and it has never previously been recorded in Croatia. Orchis × beyrichii (Rchb. f.) A. Kern. and O. × angusticruris Franch are rarely recorded hybrids in which O. simia Lam. participates, the first by crossing with the species O. militaris L., and the second with O. purpurea Huds.

Integrating African Indigenous Education in the Curriculum: A Learning Curve for South Africa
Authors: Kugara Stewart Lee , Mdhluli Tsetselelane Decide
Published: December 2023

Even though Western education is indispensable and became a game changer, its adoption in the mainstream education system (curriculum) has substantially strained the passing of relevant skills, values, and knowledge to most African communities. The adoption of Western education was not tailored to the context, realities, and needs of most indigenous communities. The popular and accepted Western education has been applauded for preparing graduates who mostly look for employment, do not resonate with their realities and environment, and can barely create jobs with the acquired education. Unlike indigenous education, which prepared the young ones to face their immediate future realities and contribute to the development of the community, Western education seems far from equipping Africans to understand themselves and their surroundings. Grounded in the African Renaissance, this paper explores African indigenous education in a bid to draw lessons from it. To achieve this, a conceptual paper is framed from a review of literature on Google scholar, DHET accredited journals, Scopus, and other relevant credited sources. The paper does not seek to undermine the importance and value of Western education in the curriculum but advocates for the adoption of indigenous education to bring positive impact to African societies. Collaborative efforts are recommended for the revival, adoption, and continuation of indigenous education without looking at it as inferior.
Cobble Stone Mining Tools - Evidence of Their Use in the Bronze Age Mines of Britain and in Current Archaeological Experiments Investigating Ancient Mining and the Processing of Metal Ores
Authors: Timberlake Simon
Published: December 2023

The characteristic artefacts of Early Bronze Age metal ore mining are cobble stone mining tools. The current study suggests that within  these tool assemblages it is normal to see some sort of use specialisation and opportunistic re-use of broken tools, whilst the wear pattern and modification to these suggests the creation of ad hoc tool kits, and the use of both hand-held and hafted hammers. At  some of the sites more than 90 % of cobbles used show only minor evidence for purposeful modification (such as a pecked groove  designed for hafting), yet extensive experimentation has demonstrated that many of these tools could have been, and probably were used with handles. Some sort of discrimination in the collection of cobbles at source is suggested by the evidence for consistency in  size, shape, weight and lithology of the stones. In West Wales we find suitable cobbles brought up to 25 km inland from the storm beaches on the coast to be used at these upland sites. Experimental archaeology has been successful in predicting the types of tools to be found during the archaeological excavation of sites; this includes the use of antler picks and bone scrapers and chisels which often don’t survive within acidic mining environments. As regards stone tools, experiments have also shown how the most rudimentary  artefacts might be used in the processing and concentration of metal ores, including those of copper and gold. The current paper  presents a body of archaeological evidence and experimental research, which is likely to be universally relevant to the study of some of the most ancient mines and mining areas in Europe.

Authors: HERMOSILLO ANDUAGA Gustavo Cesar , Kaplan Navarro José César , Padilla Torres Dr. Hugo Neftalí , Félix Gil Lic. Juan Manuel
Published: December 2023

El pan ha sido un alimento básico en México desde la época prehispánica. Según un estudio de la Universidad Autónoma de México, los antiguos mexicanos preparaban una variedad de panes con diferentes harinas, como maíz, amaranto, chía y maguey (Barros y Buenrostro, 2007). Estos panes eran parte de la dieta diaria de los mexicanos y se preparaban en hornos de barro.

Si bien es cierto que en la ciudad existen panaderías que ofrecen pan artesanal y pan gourmet, no tienen en su oferta todos los tipos de pan que se presentan en este proyecto. Las personas que les gusta consumir pan artesanal no se encuentran totalmente satisfechas ya que hay puestos en los que no se venden los productos o bien los encuentran, pero no están a un precio accesible para ellos. De ahí la necesidad de elaborar un estudio para evaluar la conveniencia de abrir un negocio de panadería gourmet en Navojoa.  En este estudio se muestran los resultados obtenidos de la aplicación de  la metodología para la formulación y evaluación de proyectos de inversión con el propósito de justificar en forma razonada la toma de decisiones.

A través de dicha metodología se obtiene una prospectiva de datos cuantitativos y cualitativos respecto de la demanda, oferta, estrategias de comercialización, aspectos organizativos, aspectos legales, identificación del producto, capacidad de producción, ubicación, el proceso de producción, la inversión, ingresos y costos. Con lo anterior se pretende mostrar al emprendedor las posibilidades y riesgos a considerar al poner en marcha este proyecto.

In the era of the 4th industrial revolution and the development of standards such as IEC 61850, it is necessary to make a complete change of view in the domain of critical services in the control and management of power systems. The former acceptance of an "isolated" system as super secure is no longer an excuse for not investing in cyber security. The examples are different, but most "cyber intrusions" into industrial facilities happen through physical contact. To improve business and keep pace with global trends, electrical companies must change their processes. A turnaround is needed in personnel required to maintain and install the systems. In addition to OT, which has been primary until now, the input of IT and Cyber security personnel is also necessary. In this way, the conditions are met for the release of some traditionally critical services through IP. An example of this is Teleprotection. The implementation of Teleprotection has been done in a couple of ways so far. Through dedicated optical fiber, which is probably the most expensive, or through TDM/SDH systems. With the advent of IP MPLS networks, many traditional systems have been replaced and manufacturers have essentially stopped development. A combination of, for example, DWDM technology and IP MPLS is something that is most often encountered in practice today. The aim of this work is to show that IP MPLS is good technology for running critical services like Teleprotection. Various texts by leading world experts in the field of the "Smart grid" concept, as well as practical works from abroad on the topic of Teleprotection, will be used as the basis of this work. In these works, the emphasis is primarily on reliability, as the basis for the functioning of any service, but in addition to reliability, attention is also paid to things like scalability, maintenance costs, complexity of implementation and future needs of the network. All these parameters together provide a good basis to make a smooth transition from traditional solutions to new "smart" industrial solutions, which rely heavily on IP.

The development of new technologies has significantly contributed to the modernization of the electricity sector. In this regard, the trend of multifunctional meter installation has been current for the last few years. Their biggest advantage is the possibility of remote data transmission and management of multitude meters from a central place. The communication with the meters is realized by the electricity network using a PLC (Power Line Carrier) technology. All advantages of this type of meter are available only if the communication works perfectly. However, the situation in practice is significantly different and the narrowband noise stands out among the many problems that can endanger the proper operation of multifunctional meters. In general, the narrowband noise represents the disturbance overlapping with the signal and has a tendency to hide the content of the information. The focus of this work is to explain how narrowband noise becomes developed in specific frequency range, depending the source that creates it. It will be explained how this kind of noise appears, what problems it causes, how to detect noise and how it is possible to remove sources of this disturbance. Finally, the presence of narrowband noise increases the number of not commisioned and unreachable electricity meters that directly attacks operations of the distributor of electricity. An important component of the work will consist of measurements made by specialized PLC instrument.
