Abstract: A method for evaluation of the Advanced Studies and Research Center (Cinvestav) at the National Technology Institute of Mexico, Library’s periodical collection is described. An evaluation matrix is used to calculate the cost-benefit of periodicals from quantitative and qualitative indicators. Citing analysis of periodicals and dissertations are made and aspects like the impact factor, statistical analysis of use, and suscription costs are also considered. The results obtained allow the evaluation of the general collection status, according to user’s necessities. This study offers elements which make the taking of decisions easier during budget restrictions, reorientation of financial resources, improvement of collections and to increase the efficiency of library services. This method could be useful for any libraries with similar characteristics to the Cinvestav. En este trabajo se aplica un método para evaluar la colección de publicaciones periódicas vigentes del Centro de Investigación y de Estudios Avanzados (Cinvestav) del Instituto Politécnico Nacional (IPN), de México. Se utiliza una matriz de evaluación para la obtención del índice costobeneficio, a partir de la aplicación tanto de indicadores cuantitativos como cualitativos. Se realizan estudios de citación, tanto en revistas como en tesis, y se toman en consideración aspectos tales como el factor de impacto de las publicaciones, datos estadísticos de uso y costo de las publicaciones. Con los resultados obtenidos se pudo evaluar el estado de este acervo en función de las necesidades de los usuarios potenciales y reales. Se ofrecen elementos que facilitarán la toma de decisiones por ajuste presupuestal, la reorientación de recursos, la mejora de la colección y de algunos servicios bibliotecarios. El método aplicado puede ser de utilidad para cualquier biblioteca con características similares a las de este centro de investigación.

Lidocaine-Induced Cell Growth of Human Gingival Fibroblasts. Role of Na+-K+-ATPase and PKC Activities  [PDF]
Emmanuel Quinteros Villarruel, Betina Orman, Enri Borda
Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.58090
Abstract:

Background: Evidences have shown that local anaesthetics are clinically useful compounds that exert a pharmacological effect by blocking nerve impulse propagation and also it is able to provoke proliferation and cell growth. Aims: The aim of this study was to investigate the proliferation and cell growth capacity of lidocaine on human gingival fibroblast cells and the different signal pathways involved in its effect. Method: For this purpose in vitro cultures of human gingival fibroblasts were assayed and the effects of lidocaine on proliferation and cell DNA synthesis, Na+-K+-ATPase and PKC activities and K+ efflux were also evaluated. Results: Lidocaine stimulated in a concentration-dependent manner proliferation and cell growth of human gingival cells and the mechanism involve an increment in Na+-K+-ATPase and PKC activities, which led to an increase in K+ release. All of these effects were blocked by tetrodotoxin, ouabain and calphostin C. In addition, PMA (activator of PKC)

Las escuelas de los profetas
Francisco Quinteros del águila
Apuntes Universitarios , 2013,
Abstract: The author explores the relationship between current education and schools of the prophets as an educational model. This is part of a historical study to identify the schools of the prophets in the Bible and in the writings of Ellen White. This paper proposes a reflection on christian education from a biblical platform, which provides for a spirit of deep christian devotion and the teachers, the relationshipof the study and work as a distinctive feature of the student as well as personalized tutorial attention, which is equivalent to an educational model that well would forceteachers and administrators to imitate.
Los genoveses, el adelantado Pedro Fajardo y Enrique IV: comercio, fraudes y ambiciones territoriales en el Reino de Murcia (1454-1474)
Quinteros Cortés, Javier
Anuario de Estudios Medievales , 2011,
Abstract: This article analyzes the exceptional privileges that Governor Pedro Fajardo and the City Council of Murcia granted to the Genoese merchants between 1454 and 1474, mostly to the Negro and Spínola families, to import and export products to and from the other extreme of the border of the Kingdom of Granada, with guaranteed insurances for the incomes of the city. This security proves an absence of danger in the commercial transit in the coasts of Granada and challenges the idea of rivalry between the Governor and the king of Granada formulating a new hypothesis: a mercantile alliance between both ringleaders that protected the Kingdom of Murcia of an economic blockade on the part of Castilian king Henry IV after the conflict with the unsuccessful Alphonso XII. El presente artículo analiza los excepcionales privilegios que el Adelantado Pedro Fajardo y el Concejo de Murcia concedieron a los mercaderes genoveses entre 1454 y 1474, principalmente a las familias Negro y Spínola, para importar y exportar productos desde y hacia el otro extremo de la frontera del Reino de Granada, con seguros avalados con las rentas de la ciudad. Esta seguridad en el tránsito comercial demuestra una ausencia de peligro en las costas granadinas que pone en entredicho la idea de rivalidad entre el Adelantado y el rey de Granada formulando una nueva hipótesis: una alianza mercantil entre ambos cabecillas que protegía al Reino de Murcia de un bloqueo económico por parte del rey Enrique IV tras el conflicto con el fallido Alfonso XII.

A morphology-based phylogeny of Phymaturus (Iguania: Liolaemidae) with the description of four new species from Argentina
Lobo, Fernando;Quinteros, Sebastián;
Papéis Avulsos de Zoologia (S?o Paulo) , 2005, DOI: 10.1590/S0031-10492005001300001
Abstract: phylogenetic relationships within the liolaemid lizard genus phymaturus were studied using parsimony analysis of morphological data. the data set includes 133 characters: 28 described in the literature as apomorphies of the three genera of liolaemidae (ctenoblepharys, liolaemus, and phymaturus), 21 published characters of allozymes and karyology, 53 characters taken from external morphology across all terminals of phymaturus, and 31 from the skeletal anatomy. this data set includes representatives of 10 of the 12 species currently recognized in the literature plus twelve other terminals considered in this study and representing independent lineages assigned to patagonicus or palluma. four of these terminals are described in the present study as new species, one belonging to the palluma group and the other three to the patagonicus group. we performed four analyses using different methods of coding binary polymorphic characters, and a new method for treating continuous characters. the traditional division of the genus in two groups is not supported here, with the patagonicus group resulting paraphyletic in some of the analyses. the palluma group is monophyletic and supported by many characters. a majority rule consensus tree of all runs recovers a reasonably well-resolved topology of the group. all analyses recovered a northern subclade within the palluma group, formed by species distributed in argentina from northern of san juan province (north to 30 degrees of latitude). in this analysis palluma from el planchón (chile) was found to be more closely related to this northern subclade than any other "palluma" form.
