Material And Methods: 20 oral medicine specialists from the national registry of specialists in Chile and 20 general dental practitioners were invited to participate. Each participant reviewed 33 cases with digital images of oral mucosa lesions and was asked to submit diagnostic hypotheses.

Single nucleotide polymorphisms of ANKK1, DDR4, and GRIN2B genes predict behavior in a prospective cohort of Mexican children and adolescents.

Numerous studies have established associations between single nucleotide polymorphisms (SNPs) and various behavioral and neurodevelopmental conditions. This study explores the links between SNPs in candidate genes involved in central nervous system (CNS) physiology and their implications for the behavioral and emotional aspects in children and teenagers. A total of 590 participants, aged 7-15 years, from the Early Life Exposures In Mexico To Environmental Toxicants (ELEMENT) cohort study in Mexico City, underwent genotyping for at least one of 15 CNS gene-related SNPs at different timepoints.

Evaluation of saliva as a complementary technique to the diagnosis of COVID-19: a systematic review.

Background: Infectious disease coronavirus 2019 (COVID-19) is caused by the SARS-CoV-2 virus, and it mainly affects the upper respiratory tract. The gold standard for its diagnosis is real-time reverse transcription polymerase chain reaction (RT-qPCR) performed on a nasopharyngeal swab. In contrast, testing saliva has significant advantages as a diagnostic method.

Governance and policy limitations for sustainable urban land planning. The case of Mexico.

In the last 25 years, unplanned and dispersed urban development has become the norm rather than the exception mostly in medium and small cities of the global south, a region with high poverty rates and weak institutions in charge of land use changes. This paper is based on environmental discourses and governance policy integration to address the limitations in preventing the conversion of open land, which provides ecosystem services, into settlement land. It analyzes the case of the Metropolitan Zone of Queretaro in central Mexico, which has experienced particularly high rates of urban expansion in recent years.
