Authors: Hamdi Tasya Puteri Aulia , Setiawan Rangga , Solihati Nurcholidah
Published: November 2024

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian glukosa dan inhibitor glikolisis terhadap viabilitas sperma domba lokal. Penelitian ini dilaksanakan pada bulan Januari - Mei 2024 dengan objek penelitian berupa semen dari tiga pejantan domba lokal yang berumur 2-3 tahun. Metode Rancangan Acak Lengkap (RAL) digunakan pada penelitian ini dengan 4 perlakuan yaitu tanpa pemberian glukosa (P0), pemberian glukosa 27 mM (P1), 54 mM (P2), dan 108 mM (P3) dengan inkubasi pada 37°C selama 0-60 menit. Setiap perlakuan diulangi sebanyak 5 kali. Kemudian setelah perlakuan optimal pada eksperimen pertama diketahui, dilanjutkan dengan eksperimen kedua dengan pemberian 3-MCPD 0, 0,5, 1, dan 2 mM pada media bufer yang mengandung glukosa 27 mM. Setiap perlakuan diulang 5 kali. Data hasil penelitian dianalisis menggunakan sidik ragam dan dilanjutkan dengan uji Tukey HSD. Hasil penelitian menunjukkan bahwa pemberian glukosa pada dosis tertentu secara signifikan mempertahankan viabilitas sperma. Pemberian glukosa 27 mM (P1) nyata mampu mempertahankan viabilitas lebih tinggi yaitu 75 ± 2,7%, dibanding P0 (67 ± 2,4%), P2 (74 ± 0,71%), dan P3 (72 ± 0,69%) yang berarti bahwa sperma menggunakan glukosa untuk mempertahankan integritas membrane. Namun, pengaruh glukosa dalam mempertahankan viabilitas sperma terhambat dengan kehadiran 3-MCPD (0,5 mM, 65,8 ± 1%; 1 mM, 61,6 ± 1,2%; dan 2 mM, 55,4 ± 2,2%). Kesimpulan dari penelitian ini yaitu pemberian glukosa dapat mempertahankan viabilitas sperma kambing melalui proses glikolisis.The purpose of this research was to determine the effect of glucose supplementation and 3-MCPD (a glycolysis inhibitor) on sperm viability of Local Ram. This research was conducted from January - May 2024 with the object of research was sperm from 2 to 3-year-old male Local Ram. The research applied Completely Randomized Design (CRD) with four treatments i.e.: sperm without glucose supplementation (P0), 27 mM glucose (P1), 54 mM glucose (P2), and 108 mM glucose (P3) with incubation at 37°C for 0-60 min. Each treatment was replicated five times. Then after the optimal treatment in the first experiment was known, continued with the second experiment by adding 0, 0.5, 1, or 2 mM 3-MCPD in a buffer medium containing 27 mM glucose. Each treatment was replicated five times. The obtained data were analyzed using the ANOVA and Tukey HSD test. The results showed that addition of glucose at certain doses significantly maintained the viability of sperm. The addition of 27 mM glucose (P1) has the highest sperm viability by 75 ± 2.7%, compared to P0 (67 ± 2.4%), P2 (74 ± 0.71%), and P3 (72 ± 0.69%), suggesting sperm utilise glucose to support their membrane integrity. However, the supporting effect of glucose on sperm viability was abolished by the presence of 3-MCPD (0.5 mM, 65.8 ± 1%; 1 mM, 61.6 ± 1.2%; and 2 mM, 55.4 ± 2.2%). In conclusion, ram sperm utilise glucose to maintain their viability via glycolysis.

Authors: Mastropasqua Nicolas , Acevedo Daniel
Published: November 2024

Hoy en día, la búsqueda de soluciones lightweight que logren resultados comparables a modelos de Deep learning robustos ha recibido particular atención debido a su implementación factible en dispositivos móviles. Uno de los problemas que podrían aprovechar esta cualidad es el de Facial Expression Recognition (FER). Considerando que una gran cantidad de datasets de expresiones faciales suelen estar anotados con emociones categóricas cuando en realidad la mayoría de las expresiones exhibidas en escenarios ‘in the wild’ ocurren como combinaciones o composición de emociones básicas, se puede hacer uso de Label Distibution Learning (LDL) como estrategia para el entrenamiento. En este trabajo se abordará el problema de FER a través de redes neuronales livianas entrenadas con LDL. Bajo el supuesto de que las imágenes de expresiones faciales deberían tener una distribución de emoción similar a la de su vecindad en un espacio de etiquetas auxiliares adecuado, como aquel determinado por la tarea de Action Unit recognition, se puede aprovechar la información de las distribuciones e incorporarla como parte la función de pérdida. Concretamente, se estudiarán en profundidad la arquitectura lightweight EfficientFace y se analizará el impacto de distintos acercamientos para implementar LDL considerando datasets ‘in the wild’ como RAF-DB, CAER-S, FER+ y AffectNet.

Published: November 2024

In older adults with disabilities, muscle weakness reduces mobility and causes postural issues. Electrical muscle stimulation (EMS) training is effective for increasing strength by inducing involuntary skeletal muscle contractions. Thus, this study aimed to examine changes in lumbar movement, muscle activity during walking, and maximum muscle strength of lower-limb joints based on an 8-week EMS exercise program for older adults with physical disabilities. Sixteen older adults (aged 56–78 years) with physical disabilities were selected and randomly assigned to either the exercise group (EG, n = 8) or the control group (CG, n = 8). EG participants were instructed to wear EMS suits and participate in an elastic band and bare-body exercise program, whereas CG participants performed the exercise program without the EMS suits. Lumbar range of motion (ROM), body circumference, partial volume, maximum muscle strength, and muscle activity were measured. Statistical analysis was performed using SPSS 28.0 for Windows, with the critical value of α = 0.05. Compared to CG participants, EG participants had a superior ROM, body volume, partial volume, maximum muscle strength (knee joints), and muscle activity while walking. These positive outcomes highlight the efficacy of combining EMS with an exercise program for strength and rehabilitation training in older adults with physical disabilities.

ABSTRACT
Introduction: Acute Myeloid Leukemia (AML) is a hematological malignancy characterized by the overproduction of myeloid stem cells in the bone marrow. Although it is a rare malignancy, AML is a type of leukemia with a poor prognosis that requires more intensive treatment. Primary therapies such as induction therapy and stem cell transplantation have developed a lot, but they have weaknesses, which are expensive and have a high risk of side effects. Sulforaphane, an herbal substance from young broccoli plants, is a potential agent in treating several types of cancer. This study aimed to review the benefits of sulforaphane as its anticancer and chemopreventive potential in AML cancer patients.
Discussion: In general, sulforaphane provides anticancer effects by inducing cancer cell apoptosis, ferroptosis along with the formation of anticancer immunity, myeloid cell differentiation, and control of cell proliferation. Anticancer effects have been studied by reducing miR-155 and miR-181a as AML biomarkers, followed by a decrease in the viability of AML cancer cells. The chemopreventive effect of sulforaphane works by inhibiting the cytochrome P450 drug metabolizing enzymes phase I and induces phase II through transcriptional activation of the Nrf2 gene, which is generally involved in antioxidative processes.
Conclusion: Sulforaphane has been shown to have anticancer and chemopreventive effects in AML patients. However, further research is needed regarding clinical effectiveness in AML management, pharmacokinetics, side effects, drug interactions, and safe doses in AML patients.

Authors: Djuanda Louis Felix , Kurniawan Jennifer Nathalie , Purnamsidi Wilbert
Published: November 2024

Pendahuluan: Kanker payudara merupakan salah satu penyakit yang jumlahnya terus meningkat setiap tahun di seluruh dunia dengan mortalitas yang cukup tinggi. Reseptor-reseptor yang terdapat pada sel kanker payudara merupakan hal penting yang diperhatikan dalam menentukan terapi yang efektif dan prognosisnya. Triple negative breast cancer (TNBC) merupakan subtipe kanker payudara yang tidak mengekspresikan sebagian besar reseptor yang umumnya diekspresikan oleh sel-sel kanker payudara. Subtipe ini memiliki mortalitas yang tinggi salah satunya akibat pilihan terapi yang sangat terbatas dan memiliki efikasi yang rendah sehingga diperlukan adanya terapi baru untuk TNBC.
Pembahasan: Ekspresi berlebihan polo-like kinase 1 (PLK1) dikaitkan dengan buruknya prognosis pada TNBC. Aktivitas PLK1 secara berlebihan menyebabkan tingginya proliferasi sel dan meningkatkan stres proliferasi sel sehingga dapat terjadi kondisi instabilitas kromosom sel. PLK1 inhibitor bekerja dengan mempengaruhi sel dan apoptosis dari sel kanker. Saat ini mekanisme PLK1 inhibitor belum diketahui jelas, tetapi telah terbukti bahwa absorpsi melalui pemberian oral cukup baik. Efek samping dari pengggunaan PLK1 inhibitor cukup umum terjadi, tetapi sebagian besar dapat diatasi dengan terapi dasar.
Kesimpulan: Mempertimbangkan terbatasnya pilihan terapi TNBC dan efikasi PLK1 inhibitor yang cukup baik mendorong rekomendasi penggunaan PLK1 sebagai terapi TNBC terutama pada pasien dengan resistensi terapi terlepas dari efek samping yang dapat ditimbulkan.

Authors: Rocha Rafael Pandolfo da , Riffel Matheus Henrique , Rosiak André , Schaeffer Lirio
Published: November 2024

Objectives: The article reviews heat transfer mechanisms in the hot stamping process, highlighting models to calculate the interfacial heat transfer coefficient (IHTC), crucial for optimizing the cooling and quality of formed products.
 
Theoretical Framework: In hot stamping of high-strength steels, the IHTC is affected by variables such as contact pressure, roughness and temperature. Cooling efficiency directly impacts the temperature distribution and martensitic microstructure of the material, essential for structural strength.
 
Method: The review compares IHTC calculation methods, such as inverse heat conduction analysis and Newton's law of cooling, detailing the convection, radiation and conduction mechanisms at each stage of the process: transfer, positioning and forming.
 
Results and Discussion: The inverse heat conduction analysis proved to be the most accurate for determining the IHTC, compared to the finite element method (FEM). The study suggests that efficient cooling channels and high conductivity materials in the matrix reduce cooling time and improve the quality of the final product.
 
Research Implications: Findings provide a basis for improving thermal management in hot stamping, reducing cycle time and increasing productivity.
 
Originality/Value: This work contributes a comprehensive reference on IHTC, assisting researchers and engineers in optimizing heat transfer and production efficiency in the manufacture of automotive components.

Authors: Azerêdo Raoni Fernandes , Szlafsztein Claudio Fabian
Published: November 2024

Objective: The objective of this study is to analyze the impacts of the extreme hydrological drought of 2023 on artisanal fishing in the Lower Amazon Integration Region and its threats to the development of the Bioeconomy Plan for the state of Pará, and to understand how this production chain is vulnerable to the risks arising from climate variability and change.
 
Theoretical Framework: In order to understand the vulnerability of artisanal fisheries to climate change, as well as to propose adaptive strategies, the Climate Lens tool was applied (OECD, 2009; Carvalho et al., 2021).
 
Method: The methodology adopted included gathering climate data and information on artisanal fishing and the 2023 drought in reports from state and non-governmental agencies and technical opinions from municipal civil defense departments. Semi-structured interviews were also conducted with directors of fishermen's colonies and officials from the municipal civil defense departments.
 
Results and Discussion: The results obtained revealed that, in vulnerable municipalities, without access to income, drinking water, food and facing social isolation, artisanal fishing has become impractical due to low water levels in rivers and lakes, resulting in an incalculable fish die-off. [synthesize the main results of the research]. In the discussion section, these results are contextualized in light of the theoretical framework, highlighting the implications and relationships identified. Possible discrepancies and limitations of the study are also considered in this section.
 
Research Implications: Based on these results, adaptive measures are recommended that can be implemented in response to existing and/or potential climate impacts.
 
Originality/Value: This study contributes to the literature by highlighting solutions for the climate scenario experienced in the Lower Amazon Integration Region and for the implementation of the Bioeconomy Plan for the state of Pará.
Queer Leadership and Identity in an Art Exhibition in the City of Rio de Janeiro
Authors: Ribeiro Tarsila Santos , Monteiro Renato Augusto da Silva
Published: November 2024

Objective: The objective of this study is to investigate how queer individuals working in art education conceive their work reality in relation to leadership through their own discursive-narrative constructions.
 
Theoretical Framework: The theoretical-conceptual contributions guiding the interface between leadership and queer theory are presented, based on emerging relational dynamics (relational queer becoming) as a producer of organizational direction, queer leadership, and professional identity meanings, providing a solid foundation for understanding the context of the investigation.
 
Method: The methodology adopted for this research involves Narrative Analysis. Data generation was conducted through interviews with twelve art educators, identifying three key moments for analyzing the narratives produced in the field: 1) Beginning of the journey: from the invitation to work to the composition of the group of art educators, 2) Experience of educational work, and 3) Looking to the future (and the past) of the journey.
 
Results and Discussion: The results affirm the existence of a relational leadership illuminated by queer theory (queer leadership) produced by the art educators in their everyday work interactions, shedding light on practices that are often denied, neglected, or deemed nonexistent by traditional leadership.
 
Research Implications: The practical and theoretical implications of this research are discussed, providing contributions to the understanding of queer leadership and the importance of positions, stances, and, especially, professional identities that emphasize the capacity to act in the face of coercive social forces, sustaining this direction under the influence of gender matrix regulations in the workplace.
 
Originality/Value: This study contributes to the literature by proposing a theoretical-methodological reconciliation through a narrative analysis that challenges fixed identity categories, aiming to affirm the existence and enhance the understanding of leadership produced by art educators.

Objective: This study aimed to assess the parents' knowledge, attitude, and practice toward pediatric ear infections in Al-Qunfudah Governate, Saudi Arabia.
Methods: A cross-sectional study was conducted in Al-Qunfudah governorate, Saudi Arabia, targeting parents of children under 18 years. The study data were collected through a pre-designed questionnaire that was disseminated through different social platforms.
Results: A study surveyed 413 parents, with a mean age of 36.5 ± 10.9 years. Good knowledge about pediatric ear infections was detected among 155 parents, representing 37.5% of the sample. High educational level and health care staff as a source of information were significantly associated with a high knowledge level about pediatric ear infections, with p-values of 0.004 and 0.001, respectively. Regarding parents' attitudes and practices regarding their children's ear infections, 368 (89.1%) parents sought medical care from healthcare providers. Causes of delay or non-seeking medical care for ear infections were lack of health insurance (23.5%, n = 97), financial incapacity (26.2%, n = 108), and parents' negligence (62.6%, n = 258).
Conclusion: The parents in Al-Qunfudah governorate, Saudi Arabia, showed below-average knowledge about pediatric ear infections. Highly educated parents and those who were dependent on the medical team as the source of their health information had satisfactory knowledge about pediatric ear infections. Parents' negligence and financial issues were the commonly reported causes of seeking medical care for children's ear infections.

Relaciones de producción, derecho y modelos de negocio: la regulación del trabajo en plataformas
Authors: Gomes Mano Felipe
Published: November 2024

La plataformatización del trabajo puede representarse con un término: precariedad. El proceso de precariedad iniciado por las plataformas digitales es muy similar al panorama general del mundo del trabajo en la periferia capitalista, por lo que entender esta puede aclarar mucho sobre el asunto. La precariedad del trabajo en plataformas está vinculada al modelo de negocio adoptado por las empresas tecnológicas, razón que invita a abrir espacios para discusiones sobre la posibilidad real de cambios efectivos a través de la regulación jurídica de las relaciones de producción capitalistas y la forma mercantilizada de trabajo. Surge entonces la pregunta: ¿es posible regular el trabajo en plataformas? El presente trabajo de carácter exploratorio presenta diferentes perspectivas sobre el proceso de plataformatización del trabajo y la actividad regulatoria, adoptando como método de procedimiento la investigación bibliográfica, y como método de abordaje el análisis deductivo con la guía general del método materialista histórico-dialéctico. Con esto esperamos contribuir a las reflexiones sobre la regulación del trabajo en plataformas digitales.

Published: November 2024

El presente artículo tiene como objetivo exponer un análisis sobre las barreras directas e indirectas de acceso a la justicia para la población afrodescendiente en la ciudad de Medellín. Para ello, se empleó una metodología mixta de rastreo con análisis documental, jurisprudencial y normativo y consulta de informes estadísticos oficiales. Como resultado de la investigación, se presentan los factores sociales, económicos, étnicos, etarios, territoriales y tecnológicos que limitan el acceso a la justicia de población NARP (negros, afrocolombianos, raizales y palenqueros). Se concluye que es necesaria una divulgación masiva de la legislación concerniente a los afrodescendientes, y la formulación de políticas públicas, planes y programas que tengan en cuenta su cosmovisión, su inclusión efectiva en diferentes escenarios, la promoción del proceso autónomo de etnoeducación y el incentivo real de espacios de derecho propio y justicia ancestral, lo cual puede allanar el camino a la igualdad material, la tutela efectiva de sus derechos y el acceso a la justicia de la población afrodescendiente en Medellín y, en general, en el país.

UV radiation can generate ROS, thereby damaging neutrophils, leading to the uncontrolled release of elastase, and causing aging. This study intends to examine the antioxidants and anti-elastase activity of the skin of Garcinia dulcis (Roxb.) Kurz fruit in serum gel extract preparation. The methods used in this research are microwave-assisted extraction and antioxidants using the ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) method. Three formulas were made with 100 x IC50, 200 x IC50, and 300 x IC50. The test results for the three formulas showed the best antioxidant and anti-elastase activity values in formula 3, with IC50 values ​​of 66.26 ppm and 111.48 ppm. This indicates that the higher the extract concentration in the formulation provides better activity in the serum gel preparation. In the third formulation, evaluation observations were made on the preparation, and a pH value close to the skin’s pH was produced, namely in formula 3. Therefore, it can be concluded that the Mundu fruit peel extract has antioxidant and anti-elastase activity. The extract is applied to cosmetic preparations and still provides good antioxidant and anti-elastase activity results.
