Introducción: los plaguicidas organoclorados (POC) pueden incrementar la producción de especies reactivas de oxígeno (ERO). Tales efectos pueden ser contrarrestados por el sistema antioxidante, el cual se encuentra también en la leche materna. Objetivo: evaluar los indicadores de estrés oxidativo en leche materna asociados a la presencia de POC y su relación con la ingesta de alimentos marinos. Métodos: la leche materna fue colectada de 108 mujeres lactantes. Los indicadores de estrés oxidativo (actividad enzimática antioxidante, concentración de glutatión, producción de radical superóxido [O 2•- ], concentración de peroxidación de lípidos y carbonilos proteicos) se analizaron por espectrofotometría...

The functional conversion of white adipose tissue (WAT) into a tissue with brown adipose tissue (BAT)-like activity, often referred to as "browning," represents an intriguing strategy for combating obesity and metabolic disease. We demonstrate that thyroid hormone receptor (TR) activation by a synthetic agonist markedly induces a program of adaptive thermogenesis in subcutaneous WAT that coincides with a restoration of cold tolerance to cold-intolerant mice. Distinct from most other browning agents, pharmacological TR activation dissociates the browning of WAT from activation of classical BAT...

Purine nucleoside phosphorylase (PNP) is an ubiquitous enzyme which plays an important role in arsenic (As) detoxification. As is a toxic metalloid present in air, soil and water; is abundant in the environment and is readily transferred along the trophic chain, being found even in human breast milk. Milk is the main nutrient source for the growth and development of neonates. Information on breast milk synthesis and its potential defense mechanism against As toxicity is scarce. In this study, PNP and antioxidant enzymes activities, as well as glutathione (GSH) and total arsenic (TAs) concentrations, were quantified in breast milk samples...

Thyroid hormone receptor (TR) agonists have been proposed as therapeutic agents to treat non-alcoholic fatty liver disease (NAFLD) and insulin resistance. We investigated the ability of the TR agonists GC-1 and KB2115 to reduce hepatic steatosis in ob/ob mice. Both compounds markedly reduced hepatic triglyceride levels and ameliorated hepatic steatosis. However, the amelioration of fatty liver was not sufficient to improve insulin sensitivity in these mice and reductions in hepatic triglycerides did not correlate with improvements in insulin sensitivity or glycemic control...

Breast milk is regarded as an ideal source of nutrients for the growth and development of neonates, but it can also be a potential source of pollutants. Mothers can be exposed to different contaminants as a result of their lifestyle and environmental pollution. Mercury (Hg) and arsenic (As) could adversely affect the development of fetal and neonatal nervous system. Some fish and shellfish are rich in selenium (Se), an essential trace element that forms part of several enzymes related to the detoxification process, including glutathione S-transferase (GST)...

BACKGROUND: In 2003, oral fludarabine was introduced in the USA for the treatment of patients with hematologic malignancies as an alternative to its intravenous (i.v.) formulation; in 2008, it was introduced in México while the i.v. formulation was withdrawn. Accordingly, i.v. fludarabine had to be replaced by oral fludarabine as part of the conditioning regimen employed to conduct allogeneic stem cell transplantation in México. METHODS: Nonrandomized retrospective analysis of 55 patients conditioned with oral fludarabine compared with 113 patients conditioned with the i...
