The article explores the significance of academic exchange between Mexican and Japanese universities, focusing on the Escuela Nacional de Estudios Superiores (ENES) Unidad León's connections and research stays at Meikai University, Topics include academic ties between ENES Unidad León and Meikai University, the timeline of academic exchanges between Mexico and Japan, and the cultural and educational similarities and differences between both nations.

Food and nutrition are the way that we get fuel, providing energy for our bodies. We need to replace nutrients in our bodies with a new supply every day. Water is an important component of nutrition. Fats, proteins, and carbohydrates are all required. Maintaining key vitamins and minerals are also important to maintaining good health. A healthy diet includes a lot of natural foods, and the effective management of food intake and nutrition are both key to good health. This manuscript describes the state of traditional foods and food customs in Japan and Mexico. [ABSTRACT FROM AUTHOR]

The article presents the discussion on talking about oral health challenges such as caries and periodontal disease prevention. Topics include concept impacting general health, wellbeing, and quality of life; and oral cavity having essential functions, such as chewing, swallowing, and communicating.

Background/aim: Alkaline extracts of several plants which contain lignin degradation products have several unique biological activities. In order to search for new biological activities of alkaline extracts of pine seed shell (APs), their anti-ultraviolet C (UVC) and macrophage stimulation activity were investigated., Materials and Methods: Anti-UVC activity was determined by the ratio of the 50% cytotoxic concentration against human melanoma cell line COLO679 to the 50% UVC-protective concentration. Extracellularly secreted nitrite (NO 2 - ) by unstimulated and lipopolysaccharide (LPS)-stimulated mouse macrophage-like cells RAW264.7 was determined by Griess method., Results: APs showed significantly higher anti-UVC activity than previously reported hot-water extracts of medical herbs. Anti-UVC activity of AP and vanillic acid was maintained for much longer than that of sodium ascorbate and vanillin. APs enhanced the production of NO 2 - to the level induced by LPS. Simultaneous addition of AP and LPS did not further increase NO 2 - production, suggesting their mechanisms of action overlap., Conclusion: The present study suggests the possible application of APs as UVC protectors and immunopotentiators via macrophage activation., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Aim: Comparative study of the growth inhibition by different types of fluoride compounds used in dentistry has been limited. We investigated the effects of sodium fluoride (NaF), diammine silver fluoride [Ag(NH3)2F] and 5-fluorouracil (5-FU) on the growth of eleven human normal and tumor cells in total., Materials and Methods: Viable cell number was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis induction was evaluated by caspase-3 activation and DNA fragmentation. Fluoride was determined using a fluoride-specific electrode., Results: All compounds had little or no growth stimulating effect (hormesis) on all cells. Ag(NH3)2F exhibited the highest cytotoxicity towards both normal and tumor cells. 5-FU had the selective cytostatic activity towards oral squamous cell carcinoma cell lines, whereas NaF was selectively cytotoxic towards glioblastoma cell lines. None of the compounds induced internucleosomal DNA fragmentation and only 5-FU induced slight activation of caspase-3 in an oral squamous cell carcinoma cell line (HSC-2). Cytotoxicity of fluoride compounds was not reduced by superoxide dismutase and catalase, reducing the possibility of the involvement of reactive oxygen species in the mechanism of action. Approximately 0.01-0.09% initially added NaF was recovered from the cells, whereas the cellular uptake of Ag(NH3)2F and 5-FU was below the detection limit., Conclusion: Cytotoxicity of fluoride compounds may not be directly linked to their tumor specificity nor to their apoptosis-inducing activity.
