The supply of relevant immunological components is stable throughout the colostrum stage. The effects of pasteurization on antibodies depend on isotype, subclass, and specificity. This information is relevant to improving the immunological quality of colostrum, especially for preterm newborns.

Vivimos en un mundo mediatizado, en el que existe una tendencia a pensar la comunicaciónen clave tecnológica e instrumental, poniendo la mirada en los medios masivos.Sin embargo, en particular en América Latina, los estudios de comunicaciónapuntan cada día con más insistencia al análisis de los procesos comunicacionalesentendidos como la construcción de relaciones y el intercambio de sentidos entre losactores sociales que comparten un determinado contexto cultural. La comunicaciónpara la salud ha sido entendida durante mucho tiempo como una herramienta paracontrolar y manipular las conductas individuales y colectivas. La revisión de esas experienciasy la puesta en práctica de una propuesta de comunicación que analiza losmúltiples sentidos de las relaciones sociales, permite avanzar hacia la construcciónde una perspectiva compleja de la realidad social. En esta perspectiva, lo comunicacionales una mirada que se articula con otras disciplinas y con los saberes vulgares,y los actores sociales tradicionalmente marginados o concebidos sólo como parte delobjeto de estudio son artífices del cambio comunitario. Se propone que los individuosy grupos que forman una comunidad puedan tomar la palabra para plantear sus necesidadesy problemas, y articularse para intervenir activamente en la búsqueda desoluciones, generando un cambio en los roles asignados tradicionalmente a los diferentesactores en materia de salud, en particular en lo referido a las relaciones depoder. La participación comunitaria es un derecho ciudadano y un imperativo democrático,pero es también una vía para aumentar la eficacia de las iniciativas sobresalud.

Arsenic has been associated with multiple harmful effects at the cellular level. Indirectly these defects could be related to impairment of the integrity of the immune system, in particular in lymphoid population. To characterize the effect of Arsenic on redox status on this population, copper smelter workers and arsenic unexposed donors were recruited for this study. We analyzed urine samples and lymphocyte enriched fractions from donors to determinate arsenic levels and lymphocyte proliferation. Moreover, we studied the presence of oxidative markers MDA, vitamin E and SOD activity in donor plasma. Here we demonstrated that in human beings exposed to high arsenic concentrations, lymphocyte MDA and arsenic urinary levels showed a positive correlation with SOD activity, and a negative correlation with vitamin E serum levels. Strikingly, lymphocytes from the arsenic exposed population respond to a polyclonal stimulator, phytohemaglutinin, with higher rates of thymidine incorporation than lymphocytes of a control population. As well, similar in vitro responses to arsenic were observed using a T cell line. Our results suggest that chronic human exposure to arsenic induces oxidative damage in lymphocytes and could be considered more relevant than evaluation of T cell surveillance.

We used fractal geometry and fractal dimension introductory argumentation as a framework to start understanding dynamical and complex biological systems to then introduce Hurst exponent estimation of chaos/no-chaos balance trend to explore the phenomenology and the information content of EEG data through time. We searched for measure proxy dynamical variables as potential biomarkers and/or endophenotypes that help us to figure out the multidimensionality and different time-scale of simultaneous and crossed functional phenomena that manifests in the brain during executing any challenging task. We found consistencies in the way intra-and interindividual differences express themselves through the EEG time series data analysis, and some degree of specificity and specialization in the frontal, temporal and occipital locations as well as brain interhemispheric cross-talk interaction modulating the chaos/no-chaos balance in the brain, during a projective process of imaging a dancing choreography. We recorded the brain activity of N = 9 professional dancers while executing the instruction of to imagine (by mean of a typical projective visualization) a future dancing performance as part of the requirement for to approve a specialization modern dance course and workshop (Kosmos In Movement, 2015).
