28. El 'argumento' tecnológico, la tecnología perniciosa y la ética

Author

Ramírez-Briceño, E. Roy

Abstract

Es necesario haber sido criado con el “espíritu militar” para entender la diferencia entre Hiroshima y Nagasaki por una parte y Auschwitz y Bergen-Belsen por la otra. Se suele decir que en el primer caso se trata de guerra y en el segundo de asesinato a sangre fría. Pero la verdad sin afeites es la siguiente: en ambos casos se trata de gente inerme, no combatientes, ancianos, mujeres y niños, y fueron aniquilados para lograr un objetivo político militar. Estoy seguro de que la humanidad va a desaparecer si el sentimiento natural de horror por las atrocidades no se sobrepone a los razonamientos especiosos.- Max Born

Abstract

El precepto de que todo ser humano es capaz de aprender y modificar su comportamiento cuando es necesario, nos induce a reflexionar que el sujeto se permite a sí mismo captar la riqueza de las múltiples dimensiones que intervienen en las situaciones que enfrenta aunque éstas sean equívocas. En tal sentido, el presente ensayo aborda el uso del error en los ambientes de aprendizaje desde una visión transdisciplinaria a través de tres aristas: los ambientes de aprendizaje, el proceso de reflexión entre error/fracaso versus error/aprendizaje y el error desde una polisemia intersubjetiva en el aprendizaje. The belief that all human beings can learn and change their behavior when necessary, leads us to think that every individual may capture in depth the richness in the multiple dimensions involved in the different situations they are to face, even if they are misleading. In this sense, this paper discusses the use of error in learning environments from a transdisciplinary view through three branches: the learning environments, the process of reflecting on error/failure versus error/learning, and error from an intersubjective polysemy in learning. Si nous partons du principe que tout être humain est capable d’apprendre et de modifier son comportement, le cas échéant, nous pouvons alors penser que le sujet se permet la possibilité de saisir la richesse des dimensions multiples intervenant dans des situations auxquelles il doit faire face, même si celles-ci sont ambiguës. Ceci dit, cet essai aborde l’utilisation de l’erreur dans les environnements d’apprentissage du point de vue transdisciplinaire à travers trois aspects : les environnements d’apprentissage, le processus de réflexion entre erreur/échec versus rreur/apprentissage et celui de l’erreur à partir d’une polysémie intersubjective dans l’apprentissage. 9-28 thairyb@gmail.com, mbriceno@uc.edu.ve semestral

Abstract

Introduccion. Estudios previos han sugerido que existe agregacion familiar de gliomas; sin embargo, los resultados no siempre han sido replicables. Sujetos y metodos. En el presente estudio de una poblacion mexicana, comparamos 100 casos de glioma con 124 controles sanos no emparentados, asi como sus familiares de primer, segundo y tercer grado (n = 3.575 y 4.520, respectivamente). Resultados. Los familiares de los casos tuvieron un riesgo significativamente mayor de desarrollar tumores cerebrales que los familiares de los controles (odds ratio, OR = 5,3; p < 0,05; intervalo de confianza al 95%, IC 95% = 1,1-25,7), su riesgo de desarrollar cualquier tipo de cancer tambien fue mayor (OR = 2; p < 0,05; IC 95% = 1,16-3,51), y este riesgo fue el doble para varones que para mujeres (OR = 2; p < 0,05; IC 95% = 1,15-3,37). Conclusion. El presente estudio apoya la existencia de agregacion familiar de neoplasias cerebrales y obliga a profundizar en el estudio de su etiologia genetica.

Abstract

Ruminant feeding in tropical regions is characterized by grass grazing. Throughout the year, grasses show variations in their availability and quality. Therefore, modern feeding systems must consider the energy requirements of the animal and the degree in which a feed or a combination of several of them could cover the nutritional requirements of the different species and physiological conditions. The central reaction for obtaining energy is carry out in the rumen in the anaerobic fermentation of the carbohydrates present in the feed. This process is developed by the ruminal microorganisms, with the purpose of generating energy for the microbial growth and the concomitant production of volatile fatty acids, methane, carbon dioxide and fermentation heat. For improving meat and milk production and quality in tropical regions, different options have been created for manipulating the energy metabolism of ruminants. Silvopastoral systems, based on Leucaena leucocephala and Panicum maximum association, allow attaining live weight gains of 770 g/d in growing cattle. It is essential the identification of Bos indicus cattle breeds or crosses with lower requirements of metabolizable energy (ME) for maintenance, so as the energy efficiency of meat production could be increased. For milk, it is possible to increase the concentration of unsaturated fatty acids (CLA's) by the tannin presence in the foliages that due to its beneficial effect on human health, could supply aggregate value to the cow's milk. Feeding practices are necessary for reducing the caloric increase of the feeding and that decrease methane emissions from the rumen through the effect of some foliages and fruits that possess secondary metabolites capable of affecting ruminal fermentation.

Abstract

Background: Malignant cell clones resistant to chemotherapy and radiotherapy frequently lead to treatment failure in patients with glioblastoma multiforme. Preliminary studies suggest that adding chloroquine to conventional therapy may improve treatment outcomes.Objective: To examine the effect of adding chloroquine to conventional therapy for glioblastoma multiforme.Design: Randomized, double-blind, placebo-controlled trial.Setting: National Institute of Neurology and Neurosurgery of Mexico.Patients: 30 patients with surgically confirmed glioblastoma confined to 1 cerebral hemisphere, with a Karnofsky performance score greater than 70, no comorbid disease, and age younger than 60 years.Interventions: Oral chloroquine at 150 mg/d for 12 months beginning on postoperative day 5 or placebo. All patients received conventional chemotherapy and radiotherapy.Measurements: Primary outcome was survival after surgery; surviving patients were followed up to October 2005. Periodic evaluation using the Karnofsky scale and imaging studies, as well as hematologic tests and ophthalmologic examinations, was done in all patients.Results: Median survival after surgery was 24 months for chloroquine-treated patients and 11 months for controls. At the end of the observation period, 6 patients treated with chloroquine had survived 59, 45, 30, 27, 27, and 20 months, respectively; 3 patients from the control group had survived 32, 25, and 22 months, respectively. Although not statistically significantly different, the rate of death with time was approximately half as large in patients receiving chloroquine as in patients receiving placebo (hazard ratio, 0.52 [95% CI, 0.21 to 1.26]; P = 0.139).Limitations: The observed advantage of chloroquine may be due to chance; differences in pretreatment characteristics and conventional treatment regimens could not be adjusted for because of the small sample size.Conclusions: Chloroquine may improve mid-term survival when given in addition to conventional therapy for glioblastoma multiforme. These results suggest that larger, more definitive studies of chloroquine as adjuvant therapy for glioblastoma are warranted. [ABSTRACT FROM AUTHOR]

45. Two models of peripheral sympathetic autoregulation: role of neuronal histamine.

Author

Campos, H A and Briceño, E

Abstract

We have studied the influence of a peripheral histamine-containing neuronal system on the sympathetic activity of the rat vas deferens. Chronic surgical interruptions of the sympathetic structures involving the adjacent histamine-containing neuronal system cause changes of sympathetic activity, as measured by the rate of disappearance of norepinephrine after reserpine administration to the awake rat. Sympathetic ganglionectomy performed on either side causes an enhancement of the sympathetic activity in the contralateral vas deferens. When the decussation of histamine-containing pathways is surgically interrupted (interganglionic section), a bilateral enhancement of sympathetic activity occurs. The histamine-containing neuronal system seems to exert a contralateral reciprocal inhibitory modulation of sympathetic activity at the vas deferens. This modulation is evoked by nervous impulses traveling in the preganglionic fiber because enhancement of sympathetic activity due to contralateral ganglionectomy is suppressed by ipsilateral decentralization. No compensatory reflexes of central origin are observed. Sympathetic enhancement due to interruption of histamine-containing nervous pathways is reversed by i.v. infusion of histamine. An H-1 or H-2 histamine receptor antagonist does not have any effect on the vas deferens sympathetic activity of the intact rat. In the heart of the deafferentated dog, removal of the left stellate sympathetic ganglion causes facilitation of the chronotropic responses induced by stimulation of the right sympathetic postganglionic nerve, also suggesting a peripheral contralateral inhibitory modulation of sympathetic activity at the heart. It appears from all these findings that a peripheral inhibitory reflex is evoked when sympathetic activity is enhanced, thus contributing to maintaining homeostasis.

Abstract

The article presents a research evaluating the efficacy of chloroquine in combination with chemotherapy and radiotherapy in the treatment of glioblastoma multiforme. The study shows that as of October 2005, 6 of the 15 patients in the chloroquine group were alive. The median survival time was 24 months for patients in the chloroquine group. However, the study was too small to provide a definite answer about whether chloroquine improved survival in patients with glioblastoma multiforme.
