Published: March 2022

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers occupying the sixth position worldwide. PI3k/Akt signaling pathway plays a significant role in regulating diverse cellular functions. This includes cell growth, proliferation and survival via inhibition of apoptosis, transcription and protein synthesis. One of the most acknowledged and approved chemotherapeutic agents is Doxorubicin (DOX) which is a non- selective class I anthracycline. In spite of DOX being one of the most acknowledged chemotherapeutic agents, its use has been limited by its toxic side effects and the development of chemoresistance. Nowadays, Thioridazine (TZ) which is a newly repurposed drug that was originally used in the treatment of psychosis, schizophrenia and anxiety, has been tested in the treatment of breast, ovarian, gastric cancers and leukemias. Methods: MTT was employed to assess the effect of TZ and DOX on the separately and in combination, with different doses and durations on the HEp2 cell line. The efficacy of both drugs was evaluated separately and in combination with different doses and durations on inhibition of cell migration on the HEp2 cell line. Results: The results of this study revealed that the highest viability was with the control group followed by the TZ group I (low dose), compared to the other groups. While it showed that the lowest mean viability was with the combination group VI (high dose) compared to other groups. Regarding the mean values of cell migration, the lowest mean value was noted in the combination group III, and the highest mean values was noted in the control group, followed by the DOX group I. Conclusion: From the results of this study it can be concluded that combination group of DOX an d TZ is a promising treatment for HEp2 cell line.

Background: The aim of the present study was to measure the clinical and pain score in these patients and to measure the level of IL-17 in saliva of patients having different forms of Oral lichen planus lesions (OLP). Subjects and methods: According to sample size calculation, the present study was done on a total of 40 subjects divided into 3 groups Group (I) Twenty patients having erosive/atrophic OLP. Group (II) Ten patients having reticular OLP and Group (III) Ten healthy control patients. Salivary samples were collected from the subjects of the three groups to evaluate the levels of IL-17 using enzyme-linked immunosorbent assay (ELISA). Results: The values of the clinical and pain score were statistically significantly higher in the erosive/atrophic group than both the reticular and healthy control subjects. The levels of IL-17 in saliva of patients with erosive/atrophic OLP were statistically significantly higher than in patients with the reticular OLP and healthy control subjects, and there was a high statistically significant difference between the reticular group and the healthy control subjects p<0.001. Conclusions: According to the results, the salivary levels of IL-17 are higher in the erosive/ atrophic type of OLP than the reticular type and both are higher than the healthy control subjects. This suggested that IL- 17 has a great role in the immunepathogenesis of OLP and may be of diagnostic value for the severity of the condition of the erosive/atrophic OLP.

PHYSICAL EDUCATION TUTORS PERCEPTIONS OF THE USE OF TECHNOLOGICAL TOOLS FOR REMOTE TEACHING DURING COVID 19
Authors: ABOAGYE Emmanuel , ADU Nathanael
Published: March 2022

The emergence of the Covid-19 pandemic created the need for the use of dissimilar remote teaching methods and strategies in many subject areas including Physical Education (PE). While this was somewhat successful in developed countries, little is known about the use of technological tools to deliver PE lessons online in developing countries. This study examined the perceptions and experiences of colleges of education PE tutors in adopting technological tools for remote teaching during the Covid-19 pandemic. Semi-structured interviews were used to collect data from 12 tutors (4 females and 8 males) in Ghana. Content analysis was employed as the tool for the analysis of the data. Based on the results, the PE tutors perceived that accessibility was a major challenge to the successful teaching of practical PE lessons online. The tutors further posited that they were motivated to deliver practical lessons online because of the Covid-19 pandemic as they don’t want students to be left idle. In furtherance, the participants recommended Transforming Teaching, Education and Learning and colleges’ management for assisting them to participate in an online course and providing them with ICT support and data. Again, the participants agreed that they prefer face-to-face to online lessons as the latter do not promote socialisation, develop only the cognitive domain and even certificates acquired online are not given due recognition. It is recommended that theory lessons should be held online while face-to-face interaction is better for practical lessons in PE due to accessibility issues connected to poor internet connectivity and difficulty in performing some of the skills online.
Security Sector in a Captured State: Act Two

Published: March 2022

In the past year and a half it has become clear that Serbia is a captured state and that the security sector is one of the most important means of preserving and cementing the situation. Security institutions have become an instrument for preserving the power of the ruling party; they participated in breaking up opposition protests, secret surveillance, intimidation and discrediting those that criticise the government. They also made sure that suspicious business deals of people close to the ruling party ran smoothly, and that the main actors involved in these activities were never held to account, either politically or legally. The trend of increasing expenditures for the security sector by additional redistribution of funds through budget rebalances has continued. The National Assembly, which - by way of its committees - should be one of the main institutions of democratic control of the security sector, has become an instrument for expressing support for the ruling party, and for public attacks on and discreditation of anyone who criticises the work of the government. The above is a consequence of the fact that the opposition has boycotted the parliamentary elections in June 2020 due to the absence of minimum conditions for holding fair elections. To legitimise the existing situation, the ruling party continues to maintain and strengthen foreign policy ties with undemocratic regimes.

Oprichtersrechten bij een SPF

In statuten van duizenden stichtingen particulier fonds (SPF) wordt bepaald dat de in de statuten vastgelegde rechten van de oprichter overdraagbaar zijn. Artikel 3:83 lid 1 en 3 BW lezende komt men tot de conclusie dat zulks niet mogelijk is.

Op grond van de combinatie van de statuten van de SPF, de met het trustkantoor gemaakte afspraken én de mogelijkheid van een mogelijk stoffelijk voordeel, komt de jurisprudentie tot de conclusie dat de oprichtersrechten een vermogensrecht zijn van de wederpartij van het trustkantoor/de oprichter van de SPF/de inbrenger van het vermogen van de SPF.

De vraag of zij overdraagbaar zijn werd in de besproken gevallen niet beantwoord. Artikel 3:83 lid 3 BW is, zolang Boek 9 BW (dat de onstoffelijke rechten zou behandelen) niet is ingevoerd, een systeemfout.

Eenmaal geconstateerd hebbende dat oprichtersrechten een vermogensrecht zijn, is het wenselijk en aantrekkelijk dat de rechter ze overdraagbaar verklaart. Zolang dit niet mogelijk is zou een geringe wijziging in lid 3 van artikel 3:83 BW een oplossing kunnen bieden.

Nowadays many companies try to adopt Industry 4.0 technology in their production lines, supply chains, etc. Industry 4.0 makes a company more profitable and automatized. There are many beneficial impacts of Industry 4.0 in companies unless there is a wrong application. Companies usually buy Artificial Intelligence software and they implement applications for them. The selection of the supplier is the most important part of applying this technology in a company. The application of Industry 4.0 in companies starts with defining the issue or eligible ways of developing. After AI solution is selected, the next phase is defining needs, budget and materials. All phases depend on the supplier. There are many qualitative and quantitative criteria in selecting the supplier of quality control AI software and this causes a lot of complicated processes. As Industry 4.0 is more popular globally, there is a significant increase in supplier numbers. When companies need to select a supplier, they want the selection process simpler and more accurate. Uncertainty in the future makes supplier selection more difficult. Therefore, Fuzzy AHP and Fuzzy TOPSIS methodologies are proper and when companies deal with uncertain situations. As a case study, Karakaya86 firm wants to implement Image Processing technology with Artificial Intelligence in their Quality Control processes for cataphoretic painting metal to the surface, and the study shows which supplier will fit with their needs for quality control defect software by using Fuzzy AHP and Fuzzy TOPSIS. We have not seen any paper similar to our study.
IMSD: Interactive Methods for Finding Similar or Diverse Answer Sets
Authors: AFEEFI Asmaa
Published: March 2022

Answer set programming (ASP) is a modeling language in knowledge representation, rooted in Logic Programming and Nonmonotonic Reasoning, which has been gaining increasing attention during the last years. In recent years, many of the researchers developed integrated development environments (IDE) for ASP programs including editors and debuggers. Other researchers focused on analyzing the answer sets, they introduced offline and online methods to find specific solutions of a given problem in answer set programming in different approaches such as phylogeny reconstruction. However, with an enormous number of answer sets could be available, the user is not interested in all of them. Thus, a navigation of the search space could be a solution to help the user to access the specific answer sets. To this end, we aim at finding similar/diverse solutions of the answer sets with a new method. The intuition behind this navigation is to make the search faster than other methods and explore information that is related to the user’s query. Afterward, we implement a tool performing the above approach in order to simplify the search task and show the applicability and effectiveness of our method. We conclude by testing the performance of the proposed tool into a real-world example of ASP programs.

The long-term success of dental implants largely depends on rapid healing with safe integration into the jaw bone. Geometry and surface topography are crucial for the short and long-term success of dental implants. This work aim to enhancing clinical performance of titanium dental implants by laser Pulses treatment to provide bone in a faster and improved osseointegration process. The results show that using different manufacturing processes (machining and powder technology) produced topographical differences. The topographical change observed from powder technology method was more than the machined one. Also Strong titanium oxide layer was observed after laser pulsed resulted in improving surface roughness and topography and it was the method of choice for complex surface geometries providing energy focused on one spot especially in the inside of implant thread. The release of Ti ion rise in first three days and after that released of Ti ions begins to stabilize after laser treatment. Finally, the histological view of implant samples after 4weeks of implantation, showed active bone formation in all implant surface which give clear indication of tissue acceptance and the appearance of mature bone was observed after laser treatments at short implantation periods.

In this study, modified asphalt binders were obtained by adding 7 different ratios waste engine oil (2%, 4%, 6%, 8%, 10%, 12% and 14%), which released as a result of routine maintenance of automobiles, to the pure asphalt binder. Then, Dynamic Shear Rheometer (DSR) experiments were applied on pure and modified asphalt binders. The rheological properties of asphalt binders at different temperatures and frequencies (loading rates) were evaluated by performing the DSR Test at 4 different temperatures (40°C, 50°C, 60°C and 70°C) and 10 different frequencies (0.01-10Hz). Then, the obtained complex shear modulus and phase angle values were estimated with Artificial Neural Networks. The results showed that the addition of 2% waste mineral (engine) oil improved the elastic properties of the asphalt binder by increasing the complex shear modulus and decreasing the phase angle values. In addition, it was concluded that the rheological parameters of asphalt binders can be successfully obtained with Artificial Neural Networks, by estimating the results with low error rate and high accuracy.
Ideología y cultura moderna de John B. Thompson
Authors: Rojas Galván José
Published: March 2022

El tema de las grandes transformaciones que han experimentado las sociedades modernas como producto del avance e innovación de los medios masivos de comunicación: telecomunicaciones, informática, satélites, etc., ha sido abordado de diferentes formas por los científicos sociales. Un grupo de estos teóricos ha planteado que los medios masivos de comunicación sirven para mantener el orden social, como un mecanismo institucionalizado para la difusión de valores y creencias colectivas. En ese sentido, la obra de John B. Thompson, Ideología y cultura moderna, representa un nuevo enfoque que rompe con los planteamientos arriba señalados y resulta ser un desafío, pues implica partir del análisis de las formas simbólicas en tanto ideológicas, transmitidas por los medios masivos de comunicación, en particular la televisión. El autor nos presenta toda una serie de argumentos encaminados a dejar en claro en qué medida y de qué manera sirven para establecer y mantener relaciones de dominación en un determinado contexto social en el cual surgen, transmiten y reciben.
La hermenéutica en la racionalidad y el discurso económico neoclásico
Authors: Berumen Resendes Manuel , Espinosa Ramírez Rafael Salvador
Published: March 2022

En este artículo se aborda el debate que hay entre la hermenéutica, la racionalidad y el discurso económico neoclásico. Se hace un recorrido por las corrientes y enfoques construidos en la ciencia económica y otras ciencias sociales; al mismo tiempo, se esbozan, entre otros temas, la manera en que la hermenéutica puede cambiar la perspectiva en el análisis económico; el debate entre la economía de la explicación y la economía de la comprensión; los límites de la racionalidad económica; el problema del discurso económico y cómo puede superarse. Los hechos económicos representados por datos construidos a partir de métodos estadísticos son interpretacionesde la clasificación y ordenación de múltiples acciones humanas. El objeto real de la economía es la realidad humana.
La gestión comunitaria del agua y su relación con las políticas públicas municipales. El caso del manantial de Patamburapio en el estado de Michoacán, 2009-2014
Authors: Casas Cervantes Abril Fabiola
Published: March 2022

La gestión comunitaria del agua es una forma de organización presente en numerosas localidades rurales del país. El surgimiento de estas formas de organización se debe, en parte, a la incapacidad de los municipios de prestar el servicio de agua potable a causa de las limitantes presupuestales y administrativas con las que operan. Esta situación ocurre principalmente en municipios pequeños. En el caso de la región a la que abastece el manantial de Patamburapio en el estado de Michoacán, los usuarios se han organizado en grupos llamados Comités del Agua, los cuales, con algunas limitaciones y deficiencias, trabajan para que el agua llegue a sus hogares. Estas organizaciones mantienen una relación cercana con las autoridades locales, pero son ellos los que marcan la agenda del agua en la cuenca. El presente texto analiza la relación entre la gestión comunitaria y las políticas públicas locales en torno del agua llevadas a cabo por la gestión pública. Se pretende ofrecer una perspectiva general de cómo ambos tipos de gestión pueden llegar a complementarse para elaborar políticas eficientes que mejoren las condiciones en las que se presta el servicio de agua potable.
Eric Hobsbawm. Un tiempo de rupturas. Sociedad y cultura en el siglo xx. Barcelona: Crítica, 2013.
Authors: Acosta Silva Adrian
Published: March 2022

Ciertos sonidos, palabras e imágenes dominan desde hace tiempo el ánimo público en una era de la historia que, como sugirió hace algunos años el gran historiador británico Eric Hobsbawn, “ha perdido el norte” y que en los primeros años del nuevo milenio “mira hacia adelante sin guía ni mapa, hacia un futuro irreconocible”. Este tono sombrío, un tanto dramático pero también realista, es un buen punto de partida reflexivo para un historiador, como lo podría ser para un sociólogo o un antropólogo preocupado por examinar la música de las emociones sobre el presente y el futuro de las sociedades. Combinado con el espectacular ascenso de la sociedad gerencial, dominada por los más variados especímenes de consultores, publicistas y empresarios o políticos que encumbran la gestión de negocios, la búsqueda de la calidad y el éxito como sinónimos de la felicidad, la planeación estratégica de las vidas de los individuos, grupos e instituciones y las relaciones entre emociones, sociedad, cultura y poder han relocalizado sus contactos, sus potencialidades, sus tensiones.
Dualismo y globalización neoliberal en Chiapas: deterioro de las condiciones de vida de los indígenas residentes, 1990-2010
Authors: Martínez Cuero Julieta , Peláez-Herreros Óscar , López-Arévalo Jorge Alberto
Published: March 2022

En este texto se analiza el rezago de los pueblos indígenas de Chiapas considerando la brecha existente entre estos y los municipios no indígenas de la entidad. Para ello, se recurre a las categorías teóricas de dualismo y heterogeneidad estructural, revisando las raíces históricas del problema. Los resultados indican que el porcentaje de residentes indígenas se relaciona intensamente con los índices de marginación, rezago social y desarrollo humano y con los porcentajes de pobreza a nivel municipal. Asimismo, se encuentra que, en el periodo 1990-2010, las diferencias entre los municipios indígenas y no indígenas continuaron ampliándose, especialmente en aquellos aspectos más ligados a la acción del mercado: los salarios, en particular, y la obtención de ingresos, en general.
Trampas de la pobreza municipales en México: ¿economía o política?
Authors: Millán Valenzuela Henio Gonzalo
Published: March 2022

Las trampas de la pobreza suelen ser frecuentes en  los municipios mexicanos, pero no en todos. Su presencia depende de variables económicas y políticas. Entre las primeras sobresalen la productividad laboral; entre las segundas, el grado de democratización y la eficacia y eficiencia de los gobiernos estatales. El artículo trata de clarificar cuál de todas ellas es la más relevante. Concluye que es el bajo grado centralización democrática de los estados lo que explica la existencia de la trampas de la pobreza.Poverty traps at the municipal level in Mexico: economy or politics? Poverty traps are frequent in Mexican municipalities, though not in all of them. Their presence depends on variables both economic and political in nature. Among the first, labor productivity stands out; while in the second, the degree of democratization and the efficiency of state governments play important roles. This article seeks to clarify which of these factors are most important. It concludes that the low degree of democratic centralization in individual states is what best explains the existence of poverty traps. Keywords: traps, poverty, institutions democracy, municipalities.
Trayectoria del Régimen de Aplicación de la Prisión Preventiva en la Constitución Mexicana de 1917
Authors: Zepeda Lecuona Guillermo Raúl
Published: March 2022

Trayectoria del Régimen de Aplicación de la Prisión La regulación constitucional de la libertad provisional y la prisión preventiva han sido objeto de intenso debate y han dado lugar, desde la promulgación de la Constitución vigente, en 1917, a seis regímenes de estas instituciones: 1917-1948, 1948-1985, 1985-1993, 1993-1996, julio de1996- junio de 2008, y desde junio de 2008 a la fecha el nuevo régimen incorporado por la reforma constitucional publicada el 18 de junio de 2008. En este apartado se describirán brevemente los diversos sistemas institucionales de la libertad provisional y la prisión preventiva que han estado vigentes en el país a partir de 1917, así como el contenido y alcance del régimen vigente. Se presenta una primera evaluación sobre la evidecnia empírica disponible para determinar si la aplicación del nuevo régimen constitucional esta alcanzando los objetivos que planteó el constituyente.[1] Con un régimen transitorio brinda un periodo de vacatio legis de hasta ocho años.

El presente artículo pretende identificar el repertorio de signos (bienes materiales e inmateriales) asociados a determinados significados que dieron cuenta del proceso de construcción de la idea de patrimonio cultural queretano desde los últimos años del régimen de Porfirio Díaz hasta la década de los cuarenta. Para la debida interpretación de este proceso, se consideraron el análisis del papel desempeñado por el fenómeno del turismo, las políticas públicas de índole nacional y local, los esfuerzos para la creación de un museo estatal, así como la publicación de textos relacionados con los monumentos y las tradiciones queretanas.
Nodos, actores y discursos en la generación de alternativas alimentarias locales en Quintana Roo y Yucatán, México, 2000-2016
Authors: Garcia Bustamante Rocio , Gracia María Amalia
Published: March 2022

Ante la vulnerabilidad alimentaria y el avance del capital privado en el sector agroalimentario distintos actores de la sociedad civil mexicana han venido construyendo iniciativas de producción, distribución y consumo local de alimentos en espacios urbanos y rurales. Mediante una metodología cualitativa este artículo identifica y caracteriza estas iniciativas en los estados de Quintana Roo y Yucatán, reconociendo sus actores, discursos y procesos de vinculación, resaltando la importancia de los intercambios materiales (alimentos y semillas) y simbólicos (discursos y conocimientos). El análisis de los resultados destaca la conformación de nodos alimentarios cuya pertinencia como experiencias sociales, habilita la conformación de alternativas alimentarias, económicas, ambientales, sociales y políticas a nivel local.
Hacia una dialéctica de la autonomía: encrucijadas del individuo en el neoliberalismo
Authors: Catanzaro Gisela , Wegelin Lucia
Published: March 2022

El artículo indaga la dimensión moral de la ideología neoliberal que caracteriza esta etapa de las sociedades capitalistas. Sostenemos que aunque la autonomía individual constituye un componente clave del discurso emprendedorista donde el individuo es postulado como único responsable de sus fracasos, su crítica no puede satisfacerse con una condena del supuesto de auto-suficiencia sino que se enfrenta a un desafío doble. Por una parte precisa destacar -tal como hace Judith Butler- tanto la responsabilidad social por la precarización como el carácter constitutivamente precario del individuo, que lo vuelve dependiente de sus lazos con otros. Por otra parte, esa dialéctica de la vulnerabilidad debería ser complementada con una dialectización de la autonomía que, junto a la identificación de su funcionamiento ideológico, posibilitara la conceptualización de su potencial crítico, asociado a una reflexividad que la economización del sujeto promovida por el neoliberalismo amenaza destruir. Luego de la introducción, donde fundamentamos la necesidad de ambas dialécticas para una crítica del presente, en el primer apartado presentamos la crítica a la precarización neoliberal propuesta por Butler, seguida de una reconstrucción de la dialéctica de la autonomía producida a partir de la lectura de la filosofía moral kantiana propuesta por Theodor Adorno. Finalmente, sobre la base de una caracterización de los sentidos en los que el neoliberalismo precariza la autonomía no sólo en su promoción de un individuo emprendedor sino también en las imágenes colectivas que se enlazan a él, sostenemos la actualidad de los contenidos críticos señalados por Adorno y la relevancia de la dialéctica de la autonomía para un pensamiento emancipador.
