Published: January 2024

As neoplasias que afetam o sistema nervoso central (SNC) são observadas em animais domésticos, com mais estudos concentrados em cães e gatos. O meningioma é um tipo de tumor que se origina nas camadas médias da meninge, conhecidas como aracnoide. Representa uma parte significativa dos tumores intracranianos em cães e é semelhante aos meningiomas encontrados em humanos. Pode surgir em várias áreas do encéfalo e, em alguns casos, pode ter características diferentes, como cistos ou componentes de sangramento. À medida que crescem, os meningiomas podem comprimir o tecido encefálico ao seu redor. Os meningiomas são classificados com base em características celulares, comportamento biológico e padrões de crescimento. Em cães, não há preferência de gênero, mas em humanos, eles são mais comuns em mulheres. Algumas raças, como Golden Retrievers, Boxers, Schnauzers Miniatura e Rat Terriers, têm uma maior predisposição para desenvolver meningiomas. Embora muitas vezes sejam classificados como benignos do ponto de vista histológico, os meningiomas em cães podem representar desafios de saúde e bem-estar devido à sua localização intracraniana. Portanto, mesmo sendo classificados como benignos, esses tumores frequentemente têm um comportamento biológico maligno. A classificação histológica dos meningiomas em cães é semelhante à dos humanos, com graus I, II e III, refletindo o potencial maligno e a tendência à recorrência. A prevalência de neoplasias intracranianas em cães aumenta com a idade, sendo os meningiomas mais comuns em cães mais velhos. O diagnóstico é realizado por meio de exames de imagem, como ressonância magnética, e a confirmação é obtida por análises histopatológicas. O tratamento pode incluir cirurgia para a remoção completa ou parcial do tumor, radioterapia e quimioterapia, dependendo da localização, tamanho e tipo do tumor. No entanto, o prognóstico pode variar conforme diversos fatores, incluindo a extensão da cirurgia, a localização do tumor e o tipo histológico.

Authors: Martínez Cantú Karina
Published: January 2024

El impresionante crecimiento urbano de las últimas décadas ha dejado en claro que las ciudades, particularmente las áreas metropolitanas, están aquí para quedarse en un futuro. Sin embargo, seguirán siendo un problema para el gobierno, pues su tamaño las hace difíciles y costosas de administrar. El presente artículo es resultado de una revisión literaria cuyo objetivo consistió en analizar los diversos enfoques de la gobernanza metropolitana y su relación con las agendas locales, además de contemplar el impacto en el crecimiento económico, asimismo, se aplicó el método de recopilación de datos y evaluación de estos mismos con la técnica de revisión documental, por lo que el tipo de investigación es cualitativo. Este artículo sostiene que a través de la gobernanza metropolitana los gobiernos locales reunidos en una zona metropolitana pueden realizar funciones estratégicas en toda el área, así como coordinar e integrar los servicios públicos. Se encontró que existen distintos indicadores que permiten medir el grado de integración de este tipo de gobiernos, y se concluye que, en el caso de Nuevo León, aunque hay modelos de gobernanza implementados que auguran la cooperación y concentración de la metrópoli es imprescindible el compromiso de los gobiernos locales para su correcta implementación.

Authors: Iancu Greceanu Iuliana Magdalena , Tănase Horia Ionuț , Dobrescu Codruta Mihaela , Dorobăț Magdalin Leonard
Published: January 2024

This article provides a comprehensive overview of oxidative stress, emphasizing its pivotal role in human health and disease progression. Oxidative stress, characterized by an imbalance between reactive oxygen species (ROS) and antioxidative defense, leads to cellular damage and exacerbates chronic diseases. Initially perceived solely as harmful, recent studies reveal ROS's dual role in cellular signaling and metabolic regulation. This shift in perspective underlines the nuanced nature of redox biology, where ROS can be both beneficial and detrimental. The article highlights the importance of antioxidative strategies, including enzymes like SOD, catalase, glutathione peroxidase, and small molecular weight antioxidants such as vitamins E and C. Advancements in redox signaling and sensor understanding have redefined oxidative stress, focusing on the need for precise diagnostic and therapeutic strategies. The paper underscores the necessity for ongoing research to characterize redox biomarkers and establish robust clinical and epidemiological reference values.

How does Dussel Help to Understand How Pre-Islamic Arab Tribes See “The Other”
Authors:   King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia, Alasmari Faiz
Published: January 2024

This paper is to examine the concept of “the other” in the pre-Islamic Arab tribes. To examine this concept, the paper focuses on “the same” as a concept that should be determined according to Dussel’s philosophy. Pre-Islamic Arab tribes had different cultures, but the concepts of “the same” and “the other” were not different and popular. The society at that time had several strata, freemen, slaves, released people, and dethroned people. “The same” has only one class, namely, freemen. The other classes are “the other.” “The other” does not have a choice to be “the other.” And their chance to be “the same” is not huge. The way to transform a self from “the other” into “ the same” is difficult and dangerous. “The same” is an ideology, not a person. If “the same” person acts against the ideology, he will find himself “the other.”

Significance of Second Near-Infrared Region (NIR-II) guided tumor detection and surgical treatment using Carcinoembryonic Antigen-Related Cell Adhesion Molecule (CEACAM) targeted probe in colorectal surgery
Authors: Mushtaq Fiza , Kamran Haneen
Published: January 2024

Respected Ma’am,
According to WHO, cancer alone killed 10 million people in 2018., making it a leading cause of mortality worldwide (1). Near-infrared fluorescence-guided surgery, a rapidly evolving technique, enables surgeons to assess tumour borders of various cancer types and lesions of other prevalent illnesses with great precision. Near-Infrared Region (NIR) radiation's ability to absorb energy at one wavelength and remit it at a different, longer wavelength stimulates substances to fluorescence, aiding the complete surgical removal of tumour tissues with negative margins, thus, improving the disease’s prognosis and decreasing chances of reoccurrence (2). Conventional fluorescence-guided surgery focuses on the first near-infrared window (NIR-I, 700–900 nm), whose tissue penetration is limited to a depth of only 1-6 mm. In contrast, the second near-infrared window (NIR-II, 1000-1700 nm) significantly reduces tissue absorption, autofluorescence, and photon scattering, enabling a deep penetration (up to 20 mm), micron-scale resolution, and an increased tumor-to-normal tissue ratio (T/NT) leading to more precise tumour removal (1–3).
A recent study in Beijing, China (3), has explored the value of the second near-infrared window (NIR-II, 1000-1700 nm) in image guided surgeries that uses 2D5-IRDye800CW, as a targeted NIR-II probe formed by the conjugation of 2D5-CEACAM5 nanobody (2D5)34 with IRDye800CW dye for intraoperative navigation in colorectal cancer which is the type of cancer known to have one of the highest mortality rates. To compare the efficacy of NIR-11 with that of NIR-1comparative studies were also conducted on mouse CA colon, orthotopic cancer and metastasis models. Compared to NIR-I, NIR-2 fluorescence had a much greater tumor to background ratio, the difference was statistically significant (p<0.0001) proving that the imaging probe was more sensitive in detecting tumours. This technique detected and resected tumours
smaller than 2 mm, making it the most suitable option for cancer diagnosis and treatment (3).
Henceforth, it can be deduced that 2D5-IRDye800CW and NIR-II fluorescence collectively have the potential to act as a way of improvement in surgery of colorectal cancer. Studies have also demonstrated the use of NIR-II systems for imaging the vasculature, detecting sentinel lymph nodes, image-guided cancer surgery, and fluorescence endoscopy (4). Its other good attributes include high precision during image-guided procedures, over currently used NIR-I radiations (3). Finally, NIR-II fluorescence technique's crucial role in detecting and treating tumours, highlights its importance and warrants further advancement.

This study investigates the complex correlation between Adverse Adolescent Experiences (AAEs), psychological trauma, and their subsequent impact on the learning process in adolescents. The primary aim of this study is to understand how traumatic experiences affect essential cognitive functions vital for learning, including memory, concentration, and problem-solving abilities. In educational contexts, we analyze how trauma can present itself, specifically in emotional dysregulation, anxiety, depression, and behavioral issues, all of which can impede academic engagement and success. This study underscores the significance of trauma-informed educational approaches through a comprehensive analysis of existing literature and empirical research. These practices are specifically tailored to acknowledge and address the unique needs of adolescents who have undergone trauma, fostering a safe and supportive learning environment. This study also examines the importance of integrating comprehensive mental health support into educational systems, specifically focusing on how it positively affects affected adolescents' resilience and academic achievements. Further future implications can provide valuable insights for educators, policymakers, and mental health professionals to develop effective strategies that promote the academic and personal growth of adolescents who have experienced adverse and traumatic events.
