Retinoblastoma (Rb) is the most common intraocular malignancy. If left untreated, Rb can result in death within 1–2 years. However, with timely detection and proper treatment, the survival rate is as high as 98%. The primary goal of Rb treatment is to eliminate cancer and save the patient’s life, while the second goal includes preserving the eye and vision. Management of Rb requires timely detection, differentiation of the tumor from similar conditions, staging, making informed decisions about the best therapeutic approach, and close follow-up to detect any signs of tumor recurrence. There are several treatment options available for Rb. Early detection and proper treatment are essential in saving the lives and vision of children affected by Rb. Progress in developing efficient diagnostic and therapeutic techniques brings hope to patients with Rb and their families. The PubMed database was utilized to identify relevant references published during the last 35 years. This article shows basic and current concepts on managing Rb, which encompasses diagnosis, evaluation, treatment, follow-up, and challenges.
La huella de carbono es una metodología que mide las emisiones de gases de efecto invernadero (GEI). En la agricultura, Nayarit, es un importante productor de café. Este estudio se centró en calcular la huella de carbono de la producción de café cereza con manejo orgánico en la región de Cumbres de Huicicila, Nayarit. Se estimaron las emisiones de GEI y la captura de carbono anual como base para la huella de carbono final. Las emisiones alcanzaron 826.6 kg CO2eq por hectárea, siendo la producción de abonos orgánicos el principal contribuyente. La captura de carbono fue significativamente mayor, con 91,380 kg CO2eq capturados principalmente por la especie Inga sp. Esto resultó en una huella de carbono anual de 0.009 kg CO2eq/ha, lo que sugiere que la producción de café cereza con manejo orgánico en la región es amigable con el medio ambiente.
Achiote has been used since pre-Hispanic times, but today it is undervalued in Mexico and is threatened with disappearance in some regions. Therefore, it is important to focus research on this crop to enhance its value and prevent the loss of this ancestral germplasm, which is an essential part of Mexican, Latin American, and Caribbean cuisine and a source of income for small rural and indigenous producers. Furthermore, it has the potential to increase its commercial value as a natural colorant compared to synthetic ones. However, despite its properties, there is currently no information available on the nutritional characteristics of the seed produced in various regions of Mexico. The aim of this study was to determine the physicochemical characteristics, nutritional value, and antioxidant compound content of achiote seeds from Nuevo Huixtán Margaritas Chiapas (Margaritas), San Pedro Tapanatepec Oaxaca (Oaxaca), and Nuevo Jericó Palenque, Chiapas (Palenque), Mexico. The effect of the region on morphological and physicochemical characteristics, nutritional quality, and nutraceutical properties of the seed was evaluated. A statistically significant difference (p ≤ 0.05) was obtained between regions for all variables studied except for the brightness (L*) of ground seeds and the content of total phenols, C, N, and S. Margaritas seeds were the heaviest and longest, while those from Oaxaca were the smallest and presented the highest values for all whole seed color parameters, in addition to having the best nutritional quality. The antioxidant capacity (DPPH) obtained was 70.01 to 76.96% inhibition, with the maximum values found in seeds from Oaxaca and Palenque. In conclusion, Mexican achiote seeds exhibit notable nutritional and nutraceutical properties, which vary depending on the region of production, highlighting the influence of geographic origin on their composition.
The objective of this research is to identify the indicators of romantic love and define the representations of gender roles in the Korean romance series “My Secret Romance”. Adapting a qualitative, descriptive, and cross-sectional content analysis design, this study employs a systematic observational technique across all 14 episodes. To address methodological rigor, coding was conducted via a two-coder independent framework with intercoder reliability assessment (Cohen's Kappa = 0.88), establishing clear operational definitions for psychometric categories adapted from the Gender Ideology Scale and Hendrick & Hendrick's Love Attitudes Scale. Among the main findings, traditional gender role statements exhibited low direct verbal frequency (e.g., “A woman's place is in the home,” 8 occurrences; “Children suffer if their mothers work,” 4 occurrences) but profound narrative impact in constraining female autonomy. Regarding romantic love, a total of 256 behavioral occurrences were categorized, with Mania (145 occurrences) and Eros (68 occurrences) dominating the affective structure. The most frequent indicators centered on cognitive obsession (“When I am in love, I find it hard to concentrate,” 56 occurrences) and somatization of distress (“When something is wrong, I feel a knot in my stomach,” 55 occurrences). The manuscript concludes that while the textual representation in My Secret Romance naturalizes obsessive attachment and emotional dependence, such findings reflect narrative tropes within the text rather than audience reception or behavioral effects.
La producción de café en Nayarit enfrenta una paradoja contemporánea. Mientras que el mercado global crece con tasas anuales del 8-10%, el estado experimenta pérdidas de superficie cultivada. Esta contracción productiva amenaza con reducir las 3,300 hectáreas que se tenían en el 2020 a menos de 600 para el 2030. Esto ocurre en un territorio que alberga unas condiciones bioclimáticas excepcionales para producir café de alta calidad. Los resultados del modelo de distribución potencial de máxima entropía (MaxEnt) revelaron que más del 35% del territorio estatal presenta condiciones de mediana a alta idoneidad para el cultivo sostenible de Coffe arabica, particularmente en los municipios de Tepic, Xalisco y Compostela, donde variables como la isotermalidad, la precipitación y la altitud crean microclimas únicos. En este capítulo se propone transformar esta evidencia científica en una herramienta de política pública mediante la delimitación de un área prioritaria para la producción sostenible de café (APS-Café), articulando el potencial biofísico con estrategias de planeación territorial que contribuya a la reactivación sostenible del café y al ordenamiento productivo y que integre el desarrollo territorial, la sostenibilidad, la producción y la justicia social orientando a posicionar a Nayarit como potencial productor de café en la región centro-occidente de México.
