In the state of Oaxaca (Mexico, 10 km north-west of Puerto Escondido 15 degrees 55' N, 97 degrees 09' W) we were able to collect some microfungi living as parasites or saprophytes on Acacia species, some of them are causing attention for Oaxaca. Many belong to the Deuteromycotina (Hyphomycetes, Coelomycetes) and Ascomycotina. On A. hindsii: Calonectria pseudopeziza (Desm.) Sacc., Hypoxylon truncatum (Schwein. Fr.) J.H. Miller, Epicoccum nigrum Link., Zygosporium gibbum (Sacc., M. Roussau & E. Bommer) S.J. Hughes and on A. cornigera: Phyllosticta acaciicola P. Henn., Taeniolella alta (Ehrenb. ex Pers.) S.J. Hughes, Cephaliophora tropica Thaxt., Diplodia mutila (Fr. Fr.) Mont., Pleospora herbarum (Pers. Fr.) Rabenh., Gliocladium roseum Bainier, Ulocladium atrum Preuss., and different others. All species collected are listed in text.

Ethnic and racial discrimination in maternal health care in Mexico: a neglected challenge in the search for universal health coverage.
Int J Equity Health
January 2025
Center for Health Equity in Latin America, Celia Scott Weatherhead School of Public Health and Tropical Medicine, Tulane University, Louisiana, USA.
Background: Ethnic and racial discrimination in maternal health care has been overlooked in academic literature and yet it is critical for achieving universal health coverage (UHC). There is a lack of empirical evidence on its impact on the effective coverage of maternal health interventions (ECMH) for Indigenous women in Mexico. Documenting progress in reducing maternal health inequities, particularly given the disproportionate impact of the Covid-19 pandemic on ethnic minorities, is essential to improving equity in health systems.

REEs in wetland sediments from the Oaxaca coast in southern Mexico were used to infer the sources and depositional processes by involving both the geochemical characteristics and geostatistical approaches. Statistically strong positive correlation between REEs confirmed similar origin in all the cores. Light REEs (LREEs) represented >84 % of ΣREE mean concentrations varies between 47.

Endemic Yucatan Peninsula Plants with Pesticidal Potential: Herbarium-Based Literature Review.
Plants (Basel)
December 2024
Facultad de Ingeniería y Negocios San Quintín, Universidad Autónoma de Baja California, Mexicali 21100, Baja California, Mexico.
Agricultural pests present a significant challenge to humanity, often managed through synthetic chemicals that, when misused, can cause irreversible harm to both the environment and human health. This study focuses on endemic plants from the Yucatán Peninsula in Mexico, particularly from the state of Campeche, to identify their historical uses and propose an updated list of species with pesticide potential in the region. We systematically reviewed specimens from the Center for Sustainable Development and Wildlife Management (CEDESU) herbarium and local databases.

(1) Background: Chagas disease is a public health problem affecting nearly 2 million women of reproductive age in Latin America. From these, 4-8% can transmit the infection to the foetus through the vertical route, whereas horizontal transmission through milk during breastfeeding remains controversial. Therefore, the presence of () DNA in the milk of women seropositive for Chagas disease was analysed to determine whether a relationship with the infection of their children can exist.
