Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance(More)
Environmental pollutants, chemicals, and drugs have an impact on children's immune system development. Mexico City (MC) children exposed to significant concentrations of air pollutants exhibit chronic respiratory inflammation, systemic inflammation, neuroinflammation, and cognitive deficits. We tested the hypothesis that exposure to severe air pollution(More)
Exposures to particulate matter and gaseous air pollutants have been associated with respiratory tract inflammation, disruption of the nasal respiratory and olfactory barriers, systemic inflammation, production of mediators of inflammation capable of reaching the brain and systemic circulation of particulate matter. Mexico City (MC) residents are exposed to(More)
BACKGROUND The aim of this study was to evaluate effects of pyridoxine and butylated hydroxytoluene (BHT) on lipid peroxidation and on levels of 5-hydroxytryptophan and serotonin. METHODS Thirty rats (30 days of age) were used in the survey, measuring levels of lipid peroxidation (TBARS), hemoglobin, 5-hydroxytryptophan (5-HTP), and serotonin (5-HT) after(More)
BACKGROUND Controlled exposures of animals and humans to particulate matter (PM) or ozone air pollution cause an increase in plasma levels of endothelin-1, a potent vasoconstrictor that regulates pulmonary arterial pressure. OBJECTIVES The primary objective of this field study was to determine whether Mexico City children, who are chronically exposed to(More)
The objective of the present trial was to evaluate the effect of toluene and o-cresol, m-cresol, and p-cresol on serotonin (5-HT), its precursor 5-hydroxytryptophane (5-HTP), Na(+),K(+)-ATPase, total ATPase, and lipid peroxidation (TBARS) in rat brain. Evaluation of lipid peroxidation was realized by means of TBARS, determination of biogenic amines and(More)
Nutritional support is a critical step in caring for hospitalized patients both to avoid possible metabolic alterations that would worsen the patient's condition, or as a direct result of a particular disease. The purpose of the present study was to describe a procedure for the prescription of total parenteral nutrition (TPN), its administration, monitoring(More)
