Objectives: We sought to analyze exercise-derived mean pulmonary artery pressure (Mpap) - cardiac index (CI) - relationship to expand the concepts regarding its nature and to better identify pulmonary hemodynamic responders to acute oxygen breathing (AOB - 99.5%) in pulmonary…

Introduction: Patients with ST elevation acute myocardial infarction (STEMI) comprise a heterogeneous population with respect to the risk for adverse events. Primary percutaneous coronary intervention (PCI) has shown to be better, mainly in high-risk patients. Objective: The purpose of this…

Introduction: Data regarding management characteristics of non-ST elevation acute coronary syndromes (NSTE ACS) in Mexican, Hispanic and Non- Hispanic white patients are scarce. Methods: We sought to describe the clinical characteristics, process of care, and outcomes of Mexicans, Hispanics and…

We relate the fundamental stages of the long road leading to the discovery of electricity and its uses in cardiology. The first observations on the electromagnetic phenomena were registered in ancient texts; many Greek and Roman writers referred to them,…

Evidence for the clinical utility of human papillomavirus (HPV) DNA testing has increased over the years and has now become very convincing. Some specific uses of HPV detection are a) triage of women with cytological determinations of atypical squamous cells…

OBJECTIVE: Genetic factors determine bone mineral density (BMD) and peak bone density between 20 and 30 years of age, as well as bone mineral loss after menopause. BMD is a predictor of fractures due to osteoporosis and the impact of…

Introduction It is widely accepted that psychiatric comorbidity can increase the severity, chronicity, and treatment resistance of psychiatric disorders. In various studies worldwide, it has been estimated that the prevalence of alcohol use disorders in women with disordered eating behaviors…

Pinos volcanic complex is an uplifted area that exposes Mesozoic strata and mid-Tertiary volcanic and sedimentary rocks. Its stratigraphy, deformation style, and volcanism are characteristic of the Mesa Central region of central Mexico and the southeastern segment of the Sierra…

In many states of central Mexico, hardened volcanic materials called tepetate (hardened layers from tuff) cover large proportions of the land surface, and are therefore of economic and social importance. Under natural conditions, tepetates are unproductive due to their hardness…

The Quaternary Sierra Chichinautzin volcanic field (SCVF) is located at the volcanic front of the Trans-Mexican Volcanic Belt (TMVB), 350 km from the Middle American trench where the Cocos plate subducts beneath the North American plate. The SCVF…
