Degradation of nucleic acids and nucleotides in several conditions with perspectives of retrieval: A review  [PDF]
José Martínez Reyes, Lenin Ejecatl Medina Orozco, Melitón Estrada Jaramillo, Iván Vera Romero, Agustina Ortiz Soriano
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.51006
Abstract:

Deoxyribonucleic acid (DNA) or oligonucleotides, can be modified in several ways as chemical degradation by electrophilic reaction, attack of radicals, hydrolytic deamination or oxidative damage caused by ionizing radiation. This work discussed these degradation mechanisms, determining the effects on these biomolecules. The actual knowledge about DNA damages only permits partial enzymatic repair treatments.

LOS DERECHOS DE LAS PAREJAS DEL MISMO SEXO: UNA DEFENSA A PARTIR DEL PRINCIPIO DE IGUALDAD O DEL DERECHO A SER DIFERENTES?
Laura Lusma Castro Ortiz,Sergio Estrada Vélez
Meritum : Revista de Direito da Universidade FUMEC , 2012,
Abstract: La tendencia dentro del derecho comparado hacia un reconocimiento de los derechos de las parejas del mismo sexo genera retos teóricos y prácticos dentro del derecho constitucional y la filosofía política, en la medida que deben procurar por los mejores fundamentos y medios de protección de esos derechos. Un elemento común ha sido la defensa a partir del principio de igualdad, pero en modelos de Estado constitucional es necesario cualificar ese principio de corte liberal mediante el reconocimiento del derecho a ser diferente como mecanismo que ofrece una protección más efectiva frente a las decisiones mayoritarias. Así, se confirma una propensión a hacer de los derechos políticos garantías fundamentales del individuo frente a las mayorías tal como ocurre, para el caso colombiano, con el derecho a la participación y a la objeción de conciencia, reconocidos como derechos fundamentales.

Meritum : Revista de Direito da Universidade FUMEC , 2012,
Abstract: A tendência no direito comparado de reconhecimento dos direitos dos casais de mesmo sexo gera desafios teóricos e práticos no direito constitucional e na filosofia política, uma vez que devem buscar os melhores fundamentos e os meios de prote o desses direitos. Um elemento comum é a defesa com base no princípio da igualdade, mas nos modelos do Estado constitucional é necessário qualificar esse princípio de estilo liberal mediante o reconhecimento do direito de ser diferente como mecanismo que oferece uma prote o mais eficaz perante as decis es majoritárias. Confirma-se, assim, uma propens o a fazer dos direitos políticos garantias fundamentais do indivíduo perante as maiorias, assim como acontece, no caso colombiano, com o direito de participa o e a obje o de consciência, reconhecidos como direitos fundamentais.

Geochemical Prospection of the Chapala Ciénega at Michoacán State  [PDF]
José Martínez Reyes, Ivan Vera Romero, Meliton Estrada Jaramillo, Agustina Ortiz Soriano, Ignacio Moreno Nava, Francisco Gabriel Montes Ayala, Francisco García ávalos, Ernesto Mendez Ruiz
International Journal of Geosciences (IJG) , 2014, DOI: 10.4236/ijg.2014.59086
Abstract:

The geochemical prospection as a branch of Applied Geochemistry or “Geochemistry of the Landscape” studies the spatial and temporal location of geochemical anomalies in order to locate geological resources of economic value. The Ciénega de Chapala zone in Michoacán is located east of the Citala rift hosting a geological system that leads to regional hydrothermal activity, mainly the Pajacuaran and Ixtlan failures. The regional geothermics include a superficial hydrothermalism consisting of springs and wells of hot water with temperatures between 48°C and 94°C in Ixtlan de los Hervores and mud volcanoes in the water with temperatures between 48°C and 94°C in Ixtlan de los Hervores and mud volcanoes in the Los Negritos. The waters and gases of these hydrothermal manifestations have physicochemical characteristics that indicate the presence of geothermal fluids. To search for possible presence of minerals of economic value, a study of elemental chemical analysis was performed by scanning electron microscopy in samples of rock of the sierra de Pajacuaran, the result of the analysis is clearly abnormal values which may be indicative a geochemical anomaly as well as the possible presence of minerals of economic value in the region. Given the above, the area of the Ciénega de Chapala in Michoacán is a zone where work can be continued both geothermal and mineralogical exploration by conventional techniques or even totally innovative technologies.

Gamboa Ortiz,F. A.; Mendieta Zerón,H.; Monta?o Estrada,L. F.;
Anales de Medicina Interna , 2006, DOI: 10.4321/S0212-71992006000500004
Abstract: introduction: upper gastrointestinal bleeding is a common cause of medical attention, with a mortality in mexico of 8.5%. our main objective was to determine the association of this pathology with cardiac conduction disturbances and other clinical variables. material and methods: we reviewed the electrocardiograms and files of patients attended for acute upper gastrointestinal bleeding at the internal medicine service of the national medical center "20 de noviembre", they must have had a previous normal electrocardiogram; excluding those with severe hemorrhage, this means, presented with hypotension managed with intravenous fluids and/or vasoactive drugs. statistical analysis was performed using the spss10 program. results and conclusions: 56 patients were included, 34 women and 22 men; 60.7% were older than 70 years. we report an association between acute upper gastrointestinal bleeding and electrocardiographic changes, principally right bundle branch block in 30.35% of cases.
Reactividad a la histoplasmina en trabajadores de granjas avícolas en la provincia de Ciego de Avila, Cuba
Suarez Hernandez, Miguel;Fernandez Andreu, Carlos M.;Estrada Ortiz, Alfredo;Cisneros Despaigne, Eugenio;
Revista do Instituto de Medicina Tropical de S?o Paulo , 1992, DOI: 10.1590/S0036-46651992000400010
Abstract: an epidemiological survey with histoplasmin skin test was performed in 392 poultry farmers and 265 workers considered without occupational risk of exposition to histoplasma capsulatum, etiologic agent of histoplasmosis. the results were positive in 28.8% and 13.2% in both groups respectively. statistically, there was a significant difference between the two groups, so it can be considered that poultry farmers are in occupational risk of infection with h. capsulatum. in the first group, the workers which are more closely related with chicken manure showed a higher reactivity to histoplasmin skin test. the working time in the farms seems to influence in the test reactivity too.

M. Murillo Ortiz,O. Reyes Estrada,E. Herrera Torres,E. Gutierrez Ornelas,H. Gonzalez Garcia
Agricultural Journal , 2013, DOI: 10.3923/aj.2010.259.263
Abstract: The objective of this study was to evaluate the annual and seasonal changes on in situ degradability of dry matter, crude protein and neutral detergent fiber in the diet of grazing steers. For the statistical analysis a fixed effects model was used. Significant effects of years were observed in soluble fractions a, degradable b, degradation rate c of the Dry Matter (DM) and Crude Protein (CP) (p<0.05). Also was observed effects between years in the Potential Degradability of Dry Matter (PDDM), Potential Degradability of the Crude Protein (PDCP) and Potential Degradability of the Neutral Detergent Fiber (PDNDF) as well as in the Effective Degradability of Dry Matter (EDDM), Effective Degradability of Crude Protein (EDCP) and Effective Degradability of Neutral Detergent Fiber (EDNDF) (p<0.05). The values of a, b, c of DM and CP as well as the PDDM, PDCP, EDDM and EDCP of the diet in summer and in fall were higher than those observed in winter and spring (p<0.05). Soluble fraction A and degradable B as well as values of c of the Neutral Detergent neutral (NDF) in summer and fall were equal but different from those observed in winter and spring (p<0.05) while the PDNDF and EDNDF were different between seasons (p<0.05). We conclude that annual and seasonal weather changes affected in situ degradability of DM, NDF and CP in the diet selected by grazing steers.
