Volume 6 is accompanied by four issues that address specific problems in the state of Guerrero, ranging from environmental and population issues. It brings together a collection of research that reflects the diversity and depth of academic work at the Autonomous University of Guerrero and other collaborating institutions. The works compiled here address current problems in biological sciences, health, education, tourism, the environment, social sciences, and technology, offering significant contributions to the understanding and solution of regional and national challenges.

In the biomedical field, studies are presented on the expression of the REST protein as a potential biomarker in lung cancer, as well as analyses of genetic polymorphisms associated with gestational weight gain and neonatal anthropometry. This work opens new perspectives for early diagnosis and preventive medicine.

The environmental sciences section includes research on the effect of mercury on bean germination and the development of expert systems for environmental quality assessment, highlighting the urgent need to develop sustainable technologies and pollution biomarkers.

From the perspectives of social sciences and education, this issue addresses highly relevant topics such as civic political culture in the coastal regions of Guerrero, the role of women in agricultural systems, poverty and female headship, and teachers' social representations in relation to the New Mexican School model. An analysis of tourism in Acapulco, focusing on visitor expectations, satisfaction, and loyalty, and the specification of an e-entrepreneurship model, complement this issue.
