Apuntes para un análisis de las prácticas de gobierno y el presidencialismo en Colombia
Vega Diaz,Luis Felipe; Valencia Sarria,Luis Carlos;
Papel Politico , 2011,
Abstract: the purpose of this essay is to propose a reflection on government techniques as ways to produce subjectivities, where rural poverty and the new forms of urban subject coexist. these techniques coexist with the emergence of a reason of state founded on exclusionary practices based on the inclusion of objects to govern. thus, the excess of the presidential figure means new objects to new dangers, the redefinition of an itinerant subject, the validation of poverty as material and necessary condition of the government. specifically, it presents the administration of the poor as a reflection of the political form of government, i.e., a specific expression of a particular reason of state.
Progesterone regulates corticosterone elevation and alterations in spatial memory and exploratory behavior induced by stress in Wistar rats
Yolanda Diaz-Burke,Claudia Elena Gonzalez-Sandoval,Carlos Eduardo Valencia-Alfonso,Miguel Huerta
Universitas Psychologica , 2010,
Abstract: The hippocampus is sensitive to high levels of glucocorticoids during stress responses; it suffers biochemical and cellular changes that affect spatial memory and exploratory behavior, among others. We analyzed the influence of the neurosteroid progesterone (PROG) on stress-induced changes in urinary corticosterone (CORT) levels, spatial memory and exploratory behavior.Castrated adult male rats were implanted with PROG or vehicle (VEHI),and then exposed for ten days to chronic stress created by overcrowding or ultrasonic noise. PROG and CORT levels were assessed in urine using highperformanceliquid chromatography (HPLC). Implanted PROG inhibited the rise of stress-induced CORT, prevented spatial memory impairment in the Morris water maze, and eliminated increased exploratory behavior in the hole-board test. These results suggest a protective role of PROG, possibly mediated by its anxiolytic mechanisms, against corticosteroids elevation and the behavioral deficit generated by stressful situations.

Electromagnetic Field Released in Collision-Impact Events Generate in the Matrix Interface Fractal Scalable Invariant Geometric Triangular Chiral Hexagonal Structures  [PDF]
Jairo A. Diaz
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.33022
Abstract:

In biology, cancer is the most beautiful natural model of a chaotic system, which under uncontrolled proliferations, generates extreme disorder that finally causes intercellular collisions. The authors have described and documented fractal self-assembly of geometric triangular chiral hexagonal crystal-like complex organizations (GTCHC) and interface comet tail effect patterns in cancer processes. According to this novel observation cancer incorporates a real visualization world with a great surprising finding in biology, physics, and geology. This visualization platform literally allows us to see what would otherwise remain completely invisible. From theory to practice this irreducible geometric matrix allowed us to identify in geology, real measurable green infrared-electromagnetic stripe line in interface with hexagonal geomorphic pattern, triangular chiral pyramidal rock structures, geology well defined mirror images, template platform to bio signature characterization of ancestral primitive polar head-tail organization, embryoid and human-like shape pattern embedded as giant fossils in rocks that have never been seen before. Electromagnetic field released in collision-impact events generate in the matrix interphase fractal scalable invariant order of geometric triangular chiral hexagonal structures. The laws of biology and geology can finally be redirected to the laws of physics; specifically magnetic fields create a new kind of classification based on these fractal structural similarities of the relationship. Further interdisciplinary collaboration must be carried out to study these geometric self-assembly geological structures, ancient sediments and rocks that could provide insights into antecedents of life.

Geometric triangular chiral hexagon complexes and clonal embryogenic body organization on the Turin Shroud crucified man image: A predictable tissue response to injury  [PDF]
Jairo A. Diaz
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.510135
Abstract: The shroud continues to remain one of the most studied and controversial artifacts in human history. Many tests, X-ray fluorescence, reflectance, spectrometry and low energy/high-resolution X ray transmission have shown that the crucified body is not compatible with a painted image. Researchers confirm that the alleged blood is real blood. We documented the self-assembly of geometric triangular chiral hexagon complex (GTCHC) with structural organization of embryoid bodies in cancer tissues. The identification of these structures is not only limited to malignant tumors but also appears in extreme injured tissues. Our interest is to determine if we can predict and identify these patterns in the Shroud of Turin. Based on pattern recognition image was analyzed over 100 shroud images. We identified a central spectral emission line that exhibits a characteristic signature on a plot of residual electromagnetic radiation, head area narrowing and low extremities broadening, indication of decay energy changes in the velocity of the molecules in the traversal trajectory. This Electromagnetic collision event generates in the cloth stagnant blood areas with patterns identical to those identified for us in cancer damage tissues. Inflammatory cytokines activate stem cells and Notch signaling proteins in cascade of interactions to generate real clonal human embryoid template. Can we predict function from structure? These structures evoke life, regeneration, but not death. Our findings suggest the image of a crucified man on the Shroud of Turin is a real physical electromagnetic collision event in response to extreme tissue injury, with the fact that supports our previous findings in cancer tissues as real and predictable. Proteins derived from these emergent damage tissue derivate stem cells could be used to design biologic templates in regenerative medicine and develop novel strategies in cancer therapy.
