Authors: Escalante Ruth , Sivira Angélica
Published: October 2024

La Fístula Bucosinusal es una patología de los senos maxilares que se puede presentar en la consulta odontológica y se produce como consecuencia de una comunicación bucosinusal. Dicha entidad posee múltiples etiologías, siendo la más común la exodoncia de piezas dentales superiores que se encuentren en relación con los senos maxilares. La literatura reporta múltiples biomateriales que pueden utilizarse en conjunto con técnicas quirúrgicas para el cierre y curación de esta patología, entre los cuales se encuentra la fibrina rica en plaquetas. El propósito de este trabajo fue reportar dos casos clínicos de fibrina rica en plaquetas con diferentes tiempos de evolución en dos pacientes femeninas corregidos con colgajo vestibular y la fibrina antes mencionada como coadyuvante en la cicatrización. Se concluye que esta fibrina es un coadyuvante biocompatible, fácil de obtener y rentable que mejora el tiempo de cicatrización para el paciente, así como disminuye el dolor postoperatorio y mejora la respuesta inflamatoria del mismo.
Rehabilitación parcial adhesiva de un primer molar inferior derecho con displasia periapical en segunda etapa: Un hallazgo casual. Reporte de un caso
Authors: Maggiorani José , Bastardo Keilyn
Published: October 2024

En la operatoria dental se han producido cambios importantes en la aplicación clínica de restauraciones adhesivas parciales posteriores cuando hay variaciones importantes en la biomecánica dental por la pérdida de tejido dentario ya sea a nivel radicular o coronal; igualmente, el enfoque altamente conservador en los tratamientos endodónticos y de restauración es significativo. La endodoncia está relacionada a las lesiones pulpares y la selección de la restauración dental mínimamente invasiva a la cantidad de estructura dental perdida. Un diente requiere un tratamiento endodóntico por presentar patologías no asociadas a la caries dental y no relacionadas al ápice del diente como en lesiones fibro óseas benignas de los maxilares. Las lesiones de displasia periapical no ameritan en principio una intervención quirúrgica o endodóntica. Se reporta la rehabilitación parcial adhesiva de diente #46 con displasia periapical en segunda etapa en paciente con gran sensibilidad a bebidas frías. Clínicamente se observó una restauración coronaria extensa infiltrada y en la radiografía periapical una imagen radiopaca con cercanía a los cuernos pulpares y una zona radiopaca bien definida en tercio apical de la raíz mesial. La tomografía de haz cónico señalo una zona mixta, de bordes limitados por una delgada cortical, no relacionada en forma directa con el periápice mesial del molar y compatible con displasia periapical en segunda etapa. Se realiza tratamiento endodóntico y rehabilitador del diente. A los seis meses se evalúa con control radiográfico y de Cone-Beam Computed Tomograph para observar la evolución o progreso de la lesión displásica. Se concluye que la lesión displásica no presentó cambios en forma ni tamaño.

Published: October 2024

La Covid-19 et les mesures mises en place ont affecté les enseignements. Les épreuves standardisées ayant été annulées au Canada, nous avons peu d’informations sur l’ampleur des pertes d’apprentissage. Les apprentissages en lecture ont été évalué auprès de 10 880 élèves de 9-10 ans lors d’une épreuve ministérielle de 2019, réutilisée en juin 2021. On observe une baisse de 8,3 points de pourcentage en lecture entre juin 2019 et juin 2021. La taille de l’écart varie en fonction de la performance à l’épreuve: la différence est maximale pour le décile inférieur, modérée pour les déciles intermédiaires et nulle pour les déciles supérieurs. Les garçons ont subi une baisse plus importante relativement aux filles. Les perturbations pandémiques ont entrainé une baisse des performances en lecture pour les enfants, en particulier pour les plus vulnérables. Un suivi de l’évolution de la performance permettra de réduire les écarts causés par les perturbations.

Published: October 2024

Background: Ulcerative Colitis is a multifactorial disease which is characterized by recurrent periods of inflammation in the mucosal layer of the colon. Toll-like receptors (TLRs) are a class of transmembrane pattern recognition receptors that play a key role in the induction of pro/anti-inflammatory genes and in the control of adaptive immune responses. In this study, we aimed to evaluate the relation between TLR1(rs4833095) single nucleotide polymorphism and ulcerative colitis.
Methods: The study included 90 patients with ulcerative colitis and a healthy control group consisting of 90 people. Taken medical treatment, laboratory data, colonoscopy findings, extraintestinal manifestations of patients included in this study were recorded. TLR1(rs4833095) single nucleotide polymorphism was studied with RT-PCR methods.
Results: There was no increased risk for ulcerative colitis in patients with ulcerative colitis who has TLR1(rs4833095) single nucleotide polymorphism in Turkish population (p>0.05). There was no association between TLR 1(rs4833095) single nucleotide polymorphism and the spread of the disease in the colon, severity of disease and treatment required for remission in our study(p>0.05).
Conclusion: In the Turkish population, TLR1 (rs4833095) single nucleotide polymorphism was evaluated and no significant difference was found between the patients with ulcerative colitis and the control group.

Objective: Blunt chest trauma is a significant clinical problem leading to injury of the lungs that may be fatal. Experimental blunt chest trauma is well established in animal models. This study aimed to investigate whether Clara cell secretory protein (CC16) can be a biomarker in an experimentally created blunt chest trauma model.
Material and Methods: A total of 30 rabbits were used in our study. A modified bilateral blunt thoracic trauma model was used to produce different levels of lung contusion. We divided the rabbits into four groups according to the energy level at which blunt thoracic trauma was applied. Blood samples were taken from the control and trauma groups to evaluate CC16 levels at 0, 12, and 24 hours.
Results: The CC16 levels measured at the start of the experiment were significantly lower in the control and low-energy groups compared to the medium- and high-energy groups (p =.002). While there was a significant difference in CC16 levels measured at the 12th hour (p =.004), no significant difference was found among the groups at the 24th hour. Upon analyzing the change in CC16 levels over time within the groups, we observed that CC16 levels decreased from 0–12 hours and subsequently increased after the 12th hour. Histopathologically, we observed that the level of contusion increased in proportion to the severity of trauma across the different groups.
Conclusion: With the designed platform, we created a reproducible experimental model of pulmonary contusion from blunt thoracic trauma in rabbits. Increased levels of CC16 following a lung contusion could serve as a foundation for clinical decision-making. Thus, CC16 has the potential to serve as a rapid and simple biochemical indicator for acute traumatic lung injury.

Published: October 2024

Objective: Noncoding RNAs (ncRNAs) have the potential to be diagnostic and therapeutic targets, in many cancer types. miRNA ‐ mRNA ceRNA (competing endogenous RNA) network in cancer has been an interesting topic that has been studied in recent years.
We aimed to investigate the relationship of UCA1/miR-138/CDK6 network with laryngeal squamous cell carcinoma (LSCC).
Material and Methods: We studied with the cancerous tissue and as the control; neighboring normal tissue samples of the patients with diagnosis of LSCC. UCA1, miR-138 and CDK6 expression analysis was made by quantitative real-time PCR (qRT-PCR) method after RNA isolation of the samples.
Results: Expressions of cancerous tissue samples and normal adjacent tissue samples as controls were compared. CDK6 and UCA1 levels were increased and miR-138 levels were found to be decreased in cancer tissues but not statistically significant.
Conclusions: To the best of our knowledge there is no study to provide an expression profile of the UCA1/CDK6/miR-138 network for LSCC patients. Although we could not obtain statistically significant results, our results were similar with the UCA1, miR‐138, and CDK6 axis literature. Further studies with larger patient samples and LSCC cell lines may confirm the function of this axis, which might be a diagnostic and therapeutic target for LSCC.

Dichiarazioni omofobe, un vescovo e i limiti della libertà di espressione. Un commento approfondito su CEDU 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20.
ABSTRACT: The decision of the ECtHR of 31.08.2023, Amvrosios-Athanasios Lenis v. Greece (no. 47833/20), is a further step toward an increasingly dense jurisprudence on “hate speech” and the limits of freedom of expression. The public proclamation of religious doctrines that are in conflict with the values of the contracting States enshrined in the ECHR is protected to a certain extent by the fundamental right of freedom of religion and belief. However, the qualification of a statement as religious does not justify “hate speech.” The AUTHOR shows the tension between freedom of religion, freedom of expression, and protection against discrimination, and analyzes the decision against the backdrop of Article 17 of the ECHR (prohibition of abuse of rights).

Authors: Al-Bachir Mahfouz , Bakir Mohamad Adel , Ahmad Husam
Published: October 2024

Background: To date, no studies have evaluated the reliability and/or validity of methods for measuring physical activity (PA) in free-living conditions within the Syrian population.Methods: This study compared estimates of PA and sedentary behavior (SB) obtained from the ActiGraph WGT3X-TB (AG) accelerometer and the Short Questionnaire to Assess Health Enhancing Physical Activity (SQUASH). Forty-five adults (13 men and 32 women, mean age 36.9 ±8.3 years) completed the SQUASH twice, with a 45-day interval between administrations. Time spent in low, moderate, vigorous, and moderate-vigorous PA (MVPA) was calculated using the SQUASH and AG accelerometer data. Reliability was assessed by calculating the Spearman correlation coefficient between the PA items scores. Bland-Altman analysis was also performed. The validity of the SQUASH was determined using the AG accelerometer as the reference method.Results: PA levels were systematically higher when measured by the SQUASH compared to the AG accelerometer. The Spearman’s correlation coefficient for the overall SQUASH reproducibility was 0.64. The Spearman’s correlation coefficient between the calculated total activity score from the SQUASH and the AG accelerometer was 0.31, indicating moderate reliability and validity of the SQUASH.Conclusion: Given its simplicity, brevity, ease of use, and low cost, the SQUASH appears to be a suitable method for monitoring PA in Syrian adults. Further strengthening of the validity scores may be possible by providing more detailed information on the types of activities included in the questionnaire.

Ethnomathematics is a field of study that combines mathematical concepts with cultural elements in people's lives. Maimun Palace, as one of the Malay cultural heritages located in Medan, North Sumatra, offers many examples of the application of ethnomathematics in its architecture and design. This research aims to explore how mathematical concepts, such as geometry, symmetry, fractals and proportions, are implemented in the building structure, ornaments and spatial layout of the Maimun Palace. The palace's architecture reflects a blend of local Malay, Islamic, Indian and European cultural influences, each of which carries unique mathematical values. In addition, symbolic elements of certain numbers are also found in the palace design, reflecting the cultural beliefs and philosophies of the local people. The results of this research show that the Maimun Palace is an important example of how mathematics is not only applied in a technical context, but is also influenced by beliefs, aesthetics, and cultural traditions. This study contributes to increasing understanding of the relationship between mathematics and culture and the importance of preserving cultural heritage through a multidisciplinary approach such as ethnomathematics.

Data Sharing for Contestability in Data-Driven Digital Markets: An Analysis
Authors: Bhat Priyanka Vinayak
Published: October 2024

This research paper explores the unique features of data-driven digital markets and investigates the feasibility of implementing a mandatory data-sharing regime for dominant entities. The context of the study arises from the recognition that competition in digital markets operates differently from traditional markets, prompting global efforts to regulate these markets and promote competition and consumer welfare. This paper employs a policy analysis methodology, examining expert reports on data-sharing strategies from the UK and the EU. Additionally, it analyses recent amendments to the Competition Act, 2002, and relevant reports and discussions within India’s antitrust regulation framework. The paper identifies that data enables competition within these markets and recommends a mandatory data-sharing regime that optimises competing considerations, such as fairness to incumbents and maximising data efficiencies. Such a data-sharing regime would ensure that entrants in the digital market are not disadvantaged and can leverage their innovation to pose a genuine competitive threat. The paper also explores alternative approaches to promoting competition, concluding that data sharing is the most efficient solution.
A Study Beyond the See-Saw of Relevant and Global Turnover: Finding a Mechanism for Adequate Penalty
Authors: Srivastava Ankit , Doneria Tanmay , Srivastava Arnav
Published: October 2024

The Competition Act, 2002 (the Act) is the governing legislation to enforce compliance against antitrust practices in the Indian market using multiple tools, the primary being the imposition of penalties. Penalties have the effect of punishing offenders and deterring others. Under the current legislation, one of the crucial aspects while computing the amount of penalty is determining the “turnover” of the undertaking, as it is used as a proxy to determine the base fine. There exist other proxies, but “turnover” is the most accepted globally. The act of imposing a penalty is also accompanied by ensuring a balance i.e., the fine should be adequate to deter and should not be excessive to break the undertaking. Hence, the imposition of a penalty is not a mere mathematical exercise but a judicious one. With this backdrop, focusing on the Indian Competition Law, the authors in this paper will comprehensively analyze the concept of “turnover” along with an evolutionary analysis of its different shades i.e., relevant, and global turnover, and how they have failed to help in fulfilling the core objectives of the penalty regime. In the latter part of the paper, the authors provide an alternative perspective based on foreign jurisprudence to argue that “turnover” is not the only proxy available and demonstrate the best practices from around the world. Lastly, having understood the strengths and weaknesses of relevant and global turnover and gained an international perspective, the authors will be suggesting a flexible approach in the context that Indian antitrust authorities will have multiple tools/proxies at their disposal for tackling every situation with the best possible approach, but this flexibility will be exercised within a particular framework/guideline. This holistic approach is essential, as considering just relevant or global turnover would eventually defeat the very purpose of imposing penalties.
Antitrust Routine in Delineating the Frontier of SEP and FRAND-Encumbered Patents: A Comparative Study
Authors: Basu Arindam , Sahoo Anshuman
Published: October 2024

Standards-Essential Patents (SEPs), and Fair, Reasonable, And Non-Discriminatory (FRAND) licensing commitments by the SEP holders, play a crucial role in enabling cooperation amid the cut-throat competition of innovation markets. Unsurprisingly, FRAND and SEPs have been the subject of frequent antitrust scrutiny across jurisdictions in recent years. However, in a post-COVID era, markets crippled by the pandemic will desperately need regulatory relaxations across the globe. Significant shifts in policy approaches may be necessary for certain situations to encourage innovation and instil stability. Against such a backdrop, we explore the emerging trends in the SEP-antitrust intersection across the US and the EU and try to understand the policy approaches these jurisdictions are adopting by analysing the recent judicial and legislative trends in addressing the issue of antitrust intervention in FRAND-encumbered patents. We then explore the Indian jurisdiction and discuss in detail the problems and prospects of FRAND licensing in India.
Ethnicity Detection with Convolutional Neural Network (CNN): Bangladesh Perspectives
Authors: Jahan Sultana Tasnim , Mustafa Rashed
Published: October 2024

Ethnicity detection, or the automatic determination of people's ethnic backgrounds using visual data, has become important in a number of disciplines, including social sciences, demographics, and computer vision. With a focus on Bangladesh's complex cultural landscape, we describe in this paper a novel method for ethnicity detection using convolutional neural networks (CNNs). We gathered a dataset of photographs depicting members of the three main ethnic groups living in the Chittagong hill neighborhood: Chakma, Marma, and Tripura. Utilizing the DenseNet121 model's robust feature extraction skills, we customized the architecture to meet the needs of our particular ethnicity detection application. A wide range of performance indicators were used to train and assess our unique CNN model. The outcomes illustrate accurate ethnicity detection technology's potential for identifying and resolving social inequities while showcasing a promising level of accuracy. To address possible biases in the model's prediction, ethical considerations are also covered. Overall, this work advances knowledge of Bangladesh's ethnic variety and demonstrates the potential of CNNs for ethnicity detection. The results provide up new avenues for investigation and applications that advance a more diverse and inclusive society.
Exploring Sustainable Initiatives for Rural Women: Analysis of Economic Transformation of Women and Community Empowerment
Authors: Asad Md. Asaduzzaman Mondol
Published: October 2024

Bangladesh, a developing nation in South Asia, has been struggling with various challenges such as poverty, corruption, overpopulation, climate change, and violence against women ever since its independence. Half of Bangladesh's entire population consists of women, with a significant majority residing in rural areas and not participating in any economic activities. Excluding this portion of the population from participating in economic activity results in a fifty percent reduction in the development of the country. Several initiatives have been undertaken to enhance the economic well-being of women in these rural communities. This study investigates the actual circumstances of women, finds obstacles to their economic participation, and suggests measures that foster their involvement in income-generating activities. The study employed a combination of qualitative and quantitative research methods, directing the rural women of Lalmonirhat district through structured interviews and focus group discussions. Result shows that the rural women residing in this community possess inadequate levels of education and are subject to numerous prejudices. Consequently, they do not participate in any economic activities, and their fate remains unchanged by any sustainable development efforts. To improve their situation, the women in this area should increase their involvement in vocational education and gain access to information, communication, and technology. This will enable them to engage in income-generating activities and bring about sustainable improvements in their lives.

Published: October 2024

Vulnerable populations are always highly affected by any disaster. They have deficient coping capacity as they depend on daily income activities and need a diversified source of income. So, those people are highly impacted by any disease. The result of such a disaster may lead to food insecurity. Methods: For the survey, 1,598 people who got unconditional support were under consideration. Out of the total population, 317 samples were surveyed using proportionate random sampling for the study. The research methodology is a Randomized Controlled Trial (RCT) with a Pretest-Posttest Design. A smart survey through KOBO tools was done using trained local enumerators. Data collected through the survey was downloaded to Excel and analysed using Excel. Results: Cereals (99%) was the most consumed food type, while white tuber and root (2.2%) were the least consumed. Food consumed in four or more types increased from 42% to 87%. Livelihood Coping Strategies indicator (L-CSI) was used as a descriptor of a household’s coping capacity alongside the R-CSI. The responses were categorized into stress, crisis, and emergency strategies. The number of HHs under the crisis category reduced from 15.4% to 4.1%. Similarly, the number of households under the Emergency category reduced from 12.3% to 3.8%, and the number of crises reduced from 58.2 % to 6.8% Conclusion: The study showed from the calculation R-CS that conditional support of the vulnerable people increased by nearly one-third (35%) within a month of support and helped them with coping strategies.

Epidemiology of cat bites to people in Uruguay: Effects of the age and sex of the victim, season of the year and the COVID-19 pandemic
Authors: n Juan , n Javier , Willat Gabriela , Barrios Florencia
Published: October 2024

Background:
Cat bites to people are an important public health problem. However, very little information exists on the epidemiology of people bitten by cats at the level of an entire country in Latin America. Additionally, the COVID-19 pandemic significantly influenced people's lives and their relationships with pets, which could potentially affect the frequency of people bitten by cats.
Aim:
The aim of this study was to determine the prevalence of people bitten by cats in Uruguay (2010 to 2020) according to the sex and age of the victim, season of the year, and to compare the prevalence in the pandemic year (2020) with that of the pre-pandemic years (2010- 2019).
Methods:
Cross-sectional study. Cat-bite notifications for the 2010 to 2020 period were analyzed using data from the Uruguayan Ministry of Public Health (Uruguay).
Results:
The annual cat-bite rate for the 2010-2020 period was 2.1 per 100,000 people. The frequency of cat bites varied with the victim´s sex (p<0.0001), being greater in females (n=506, 66.5%) than in males (n=255, 33.5%). The age at being bitten by cats varied with the sex of the victim, with males being bitten at an earlier age than females (p<0.0001). Among the age categories of 30 to 74 years, females were bitten more than males (p<0.05). Overall, cat bites were much less frequent in the oldest age categories (over 75 years old, p<0.05). The percentage of cat bites tended to change with the season of the year (p=0.08), with most bites occurring in spring and summer. The frequency of cat-bite injuries was similar between 2020 and the pre-COVID-19 pandemic years.
Conclusion:
In Uruguay, cat bite incidents were affected by the victim's sex (more in females) and age, as well as by the season. During the initial year of the COVID-19 pandemic, the rate of cat bites was no different to those in earlier years.

Authors: Vargas Jos , Jorge Wilson , Pachorro Fidel , Alor Max , Fuster Marcelo , Jimenez Mauricio , Linares Ximena , Galvez Roberto , Parra Edson
Published: October 2024

Background:
Alpacas have reproductive traits such as induced ovulation and a higher gestation rate in the left uterine horn. Additionally, low fertility and high embryonic mortality are significant challenges in alpaca breeding. To address these issues, it is essential to study the histological changes occurring in the uterine wall during day 8 of the luteal phase.
Aim:
This research aims to describe these changes in alpacas with induced ovulation using GnRH or copulation.
Methods:
The study was conducted on 8 sexually mature fertile alpacas with a preovulatory follicle of ≥ 7 mm. Ovulation was induced with GnRH (G1, n=3) and natural mating’ (G2, n=5), confirmed by ultrasound showing the disappearance of the follicle and formation of the corpus luteum. On day 8 of the luteal phase, samples of the uterine wall from the right and left uterine horns were obtained through a midline laparotomy. A uterine lavage with PBS was also performed, and no embryo-ova was found. The tissues were fixed, processed, and stained with Hematoxylin and Eosin. Measurements of the myometrium and endometrium, the area of the superficial and deep endometrial glands, the height of the gland cells, and the height of the endometrial mucosal cells were performed using microscopy and software. The Measurements were taken in microns (um), from 12 different photographs per animal.
Results:
In G2 (copulation), greater thickness of the endometrium and myometrium, as well as a larger area of the superficial glands and cell height, were observed (p < 0.005). Additionally, the area of the superficial glands in the left horn was greater compared to the right.
Conclusion:
The thickness of the myometrium and endometrium, and the area of the superficial glands of the left uterine horn in alpacas during the luteal phase (day 8), induced by copulation (G2), show better development. This research provides new insights into changes in the histomorphometry of the alpacas uterus during this stage and is the first report in this species.
