Objective: To describe, on the basis of established norms of scientific literature, the sources of aluminum (Al3+) intake, its metabolism in the human body, its toxic effects, and its relationship with some neurological diseases. Materials and Methods: A non-systematic search of pertinent literature was conducted in PubMed, Elsevier, SciELO, Springer Link, Web of Science, and Google Scholar. Results: Sources of aluminum intake included food cooked with aluminum foil, medications, and traditionally used clays (known as “chacco”) in Southern Peru. It is estimated that the average person ingests 3-5 mg of Al3+ per day. Approximately 40% of the ingested Al3+ is retained in the intestinal coverage or secreted by the enterocytes into the circulatory system. This elevates the aluminum body levels and allows it to enter into several organs, including bones and brain. Aluminum's toxic effects...

The study was conducted in a context marked by growing concern regarding the presence of academic misconduct in higher education, which affects both the quality of learning and the ethical training of students. Objective: To identify the level of knowledge and perception that university students have regarding academic misconduct. Methodology: A quantitative approach with a non-experimental, cross-sectional design and a descriptive-correlational scope. The sample consisted of 351 students from three universities in southern Peru, selected through non-probability convenience sampling. A questionnaire evaluating three dimensions was used: knowledge of dishonest practices, misconduct committed, and perception of the severity of such behaviors. Data analysis included the Kolmogorov-Smirnov test, Spearman's correlation, and Pearson's chi-square. Results: 70% of participants showed a high leve...
