Abstract: Los estudios de ADN antiguo están permitiendo conocer nuevos datos sobre la biología de especies actuales y extintas. Las técnicas de ADN antiguo pueden ser una herramienta adicional y complementaria dentro de los estudios multidisciplinares que son necesarios para abordar distintas problemáticas arqueopaleontológicas. En este artículo repasamos algunas de las aplicaciones en estos contextos: la determinación taxonómica y sexual, los estudios para conocer el proceso de domesticación, o la estructura filogeográfica durante ciclos glaciares subrayando la existencia o no de refugios glaciares. También proporcionamos información preliminar referente a la aplicación de estas técnicas en el yacimiento de Arlanpe (Lemoa, Bizkaia). En este yacimiento hemos obtenido ADN mitocondrial de muestras de oso pardo, gran bóvido y cabra montés. Una de las muestras de oso pardo de Arlanpe está dentro del clado 3c compuesto de osos pardos extintos de Alaska. Dos de las muestras de gran bóvido de Arlanpe han sido clasificadas como uro (Bos primigenius) mediante métodos genéticos.

Abstract: El síndrome de Lyell o necrólisis epidérmica tóxica (NET) es una toxicodermia extremadamente grave e infrecuente; se caracteriza por la necrosis y el posterior desprendimiento de la epidermis en grandes áreas cutáneas tras una reacción idiosincrásica a un fármaco. Los pacientes que la padecen presentan idénticas complicaciones fisiopatológicas que los grandes quemados. Tradicionalmente se ha tratado con inmunomoduladores como los corticoides, inmunoglobulinas, ciclofosfamida, talidomida o plasmaférisis, obteniéndose una respuesta variable y en algunos casos contradictoria. Desde finales de los a os noventa, se ha ensayado en series limitadas la ciclosporina A como inmunomodulador único en pacientes con NET, mejorando resultados en términos de supervivencia respecto a estudios con otros fármacos. En este artículo se presentan 3 casos consecutivos de NET tratados con ciclosporina A. Lyell's syndrome or toxic epidermal necrolysis (TEN) is an extremely rare and dangerous severe skin disorder characterized by a high proportion of cutaneous lesions leading to necrosis and subsequent shedding of the epidermis over large areas of skin after an idiosyncratic reaction triggered by a drug. The patients who suffer it pathophysiologically have similar complications to those seen in major burns. TEN traditionally has been treated with immunomodulators such as glucocorticoids, intravenous gammaglobulin, cyclophosphamide, thalidomide or plasmapheresis. A variable, and sometimes contradictory response, has been obtained in some series. Cyclosporin A has been tested as a single immunomodulator in patients with TEN since the end of the 90s in a limited number series. The results have improved in regards to survival compared with studies with other drugs. We report three consecutive cases of toxic epidermal necrolysis treated with cyclosporin A in this article.

Into the life and death: RecA a WISE factor working to integrate survival and evolution in Escherichia coli  [PDF]
José María Gómez Gómez
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.43A059
Abstract:

Escherichia coli RecA has been considered traditionally a cellular protein with multiple vital functions working to ensure the maintenance of integrity of genome in each individual bacterial cell as well as promoting swarming migration in collectivity. On the contrary, recently it has been described that RecA promotes cellular apoptotic-like death (ALD), a pathway of programmed cellular death (PCD). In fact, RecA has been dubbed as the major apoptotic executor in E. coli. From these studies, RecA emerges as a prototypical Gin/Gan protein that despite of their intrinsic vital and lethal anfi-funcionality becomes in a WISE factor: a Worker to Integrate Survival and Evolution in E. coli evolving populations living in community. Here, I provide a review of recent experimental and conceptual advances trying to understand these RecA’s antagonistic roles in appearance contradictory under a unified biological vision.

Equilibrium Dynamics in the Neoclassical Growth Model with Habit Formation and Elastic Labor Supply  [PDF]
Manuel A. Gómez
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25087
Abstract: This note analyzes the equilibrium dynamics in the neoclassical growth model with habit-forming preferences and elastic labor supply. Habits enter into utility in a multiplicative way. The specification of the habit formation process comprises the particular cases of internal and external habits. Existence, uniqueness and saddle-path stability of the steady state are proved analytically.
A Novel Cellular Autoaggregative Developmentally CRP Regulated Behaviour Generates Massively Chondrule-Like Formations over Surface of Old Escherichia coli K-12 Macrocolony Biofilms  [PDF]
José María Gómez Gómez, Ricardo Amils
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.59086
Abstract:

How Escherichia coli bacteria develop a particular colonial, 3-D biofilm morphological pattern is still a poorly understood process. Recently, we reported a new E. coli K-12 morphotype exhibited by old macrocolonies described as volcano-like. The formative developmental process of this morphotype has been presented as a suitable experimental model for the study of 3D patterning in macrocolony biofilms. Here, we report the optical microscopy observations and genetic analysis that have unveiled the existence of a novel autoaggregative behaviour which generates massive lumpiness over the surface of the volcano-like macrocolonies. These lumpy formations are generated by the autoaggregation and strong interaction of tightly packed bacterial cells in structures with a chondrule-like appearance which give the colony’s surface its characteristic microscopic lumpy phenotype. Furthermore, they exhibit different levels of maturation from the edge to the center of the colony. Hence, its generation appears to follow a spatiotemporal program of development during the macrocolony’s morphogenesis. Interestingly, the agar’s hardness influences the morphology exhibited by these formations, with high agar concentration (1.5%, 15 g/L) suppressing its development. This new auto-aggregative E. coli’s behaviour does not require the activity of the biofilm master regulator CsgD, the adhesiveness of flagella, pili type 1, adhesin Ag43, β-1,6-N-acetyl-D-glucosamine polymer-PGA, cellulose or colanic acid, but it is under glucose repression and the control of cAMP receptor protein (CRP).

Relevance of Epistemological Pluralism for Resource Management Policies  [PDF]
Mónica Gómez Salazar
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.56039
Abstract: The common believe of a single successful form of knowing the reality is misleading. A brief analysis of many human activities reveals a pluralistic perspective of several coexisting conceptual schemes that underlie the form in which women and men know and constitute the world in which we live. Here, I will discuss the necessity of taking seriously this pluralistic perspective when developing conceptual frameworks of human activities. As an example of great interest and importance, I will consider the case of resource management that has to contemplate the conservation and the response of ecosystems to human activities that may lead to irreversible damage. Ecosystems’ activity occurs over a wide range of space and time scales and, hence, policies and proposals of solutions to ecological problems should avoid narrow and monochromatic approaches. Specifically, the Pemon perspective of fire is a good example to show that for more robust and flexible resource management we need the knowledge and experience of different cultural and disciplinary groups.

Juan José Leiva Olivencia
Didáctica, Innovación y Multimedia : DIM , 2013,
Abstract: This article aims to raise educational reflection on the potential of ICTs as tools generating multiculturalism in school. At this point, we intend to investigate critically about theoretical and practical elements of virtual learning communities to promote multiculturalism in schools. We will also discuss some experiences that are being developed in this area where there is a growing concern for cultural and educational interaction through virtual networks and platforms.
