Joostella strains are emerging candidates for biosurfactant production. Here such ability was analyzed for Joostella strain A8 in comparison with Alcanivorax strain A53 and Pseudomonas strain A6, all previously isolated from hydrocarbon enrichment cultures made of polychaete homogenates. In pure cultures Joostella sp. A8 showed the highest stable emulsion percentage（78.33%）, hydrophobicity rate（62.67%）, and an optimal surface tension reduction during growth in mineral medium supplemented with diesel oil（reduction of about 12 mN/m）, thus proving to be highly competitive with Alcanivorax and Pseudomonas strains. During growth in pure culture different level of biodegradation were detected for Alcanivorax strain A53（52.7%）,Pseudomonas strain A6（38.2%） and Joostella strain A8（26.8%）. When growing in consortia,isolates achieved similar abundance values, with the best efficiency that was observed for the Joostella-Pseudomonas co-culture. Gas-chromatographic analysis revealed an increase in the biodegradation efficiency in co-cultures（about 90%）, suggesting that the contemporary action of different bacterial species could improve the process. Results were useful to compare the efficiencies of well-known biosurfactant producers（i.e. Pseudomonas and Alcanivorax representatives） with a still unknown biosurfactant producer, i.e. Joostella, and to confirm them as optimal biosurfactant-producing candidates.

Valproic Acid,a Drug with Multiple Molecular Targets Related to Its Potential Neuroprotective Action

引用

Neuroscience & Medicine 2012年第1期3卷 107-123页

Valproic acid (VA) is used worldwide as an antiepileptic drug and a mood stabilizer. Recently, VA was shown to act on cell growth, differentiation and apoptosis, by regulating gene expression at the molecular level, through epigenetic mechanisms. Thus, VA was demonstrated to act on the chromatin remodeling what is a consequence of the drug inhibition of histone deacetylases (HDACs) activity. Other studies uncovered the potential of VA to interfere with multiple regulatory mechanisms besides HDACs, as the GSK3 alpha and beta, Akt, ERK and phosphoinositol pathways, tricarboxylic acid cycle, GABA and OXPHOS system. The review focuses on the mechanisms of action of VA, showing that HDAC inhibitors, as VA, can be successfully used in the treatment of neurodegenerative disorders. This molecule, whose biological activities range from interactions with receptors and ion channels to the regulation of many catalytic reactions, has a central role in cellular cascades that regulate gene expression. Thus, inhibitors of HDACs, by positively affecting both neuronal degeneration and cognitive deficits, appear as promising drugs against various pathological conditions and neurodegenerative diseases. VA is known to present anti-inflammatory and antioxidative properties. And, since inflammation and oxidative stress are common links in neurodegeneration, VA is a drug that, from a clinical point of view, shows a great potential as a candidate for the treatment of neurodegenerative diseases related to excitotoxic events.

The health care economic-industrial complex: Concepts and general characteristics

The strategic role of health care within the Brazilian development agenda has been increasingly recognized and institutionalized. Aside from its importance as a structural element of the Welfare State, health care plays a leading role in generating innovation. Despite this, the productive base of Brazil’s health care system is extremely fragile, jeopardizing both the universal provision of health care services and the country’s competitive insertion in the globalized environment. This suggests the need for a more systematic analysis of the complex relationships that exist between the technological and the social interests involved in the productive base of health care provision in Brazil. Therefore, the purpose of this article is to enhance our understanding of the productive base of health care, especially given its potential to contribute to a socially inclusive development model, which is the ultimate goal in Brazil.

Vocational Training and Basic Knowledge of the Mexican University Coach

Sociology Study 2015年第3期5卷 232-244页

作者： Ciria Margarita Salazar Julio Alejandro Gomez Figueroa Martha Patricia Perez Lopez CarmenSilvia vargas Pena Pedro Julian Flores Moreno Rossana Tamara Medina Valencia jose E. Del RioValdivi jose Aldo Hernandez-Murua University of Colima Mexico University of Veracruz Mexico Autonomous University of Sinaloa Mexico

This paper shows an overview of the academic and vocational training of the Mexican university coaches. Professional sports in Mexico are not sufficiently organized in all disciplines and the Olympic sporting system does not consider the university sports as a hotbed of world-class athletes. Coaches＇ academic and vocational training is one of the variables to analyze university-sporting level. A quantitative model was used to approach the topic through an adapted and validated version of a questionnaire used in Spanish populations. The sample consisted of 326 participant＇s coaches at the 2013 National Student Games. Among the findings, observed there are some aspects revealed related to the training, the domain of knowledge and the existing relationship between an empirical coach and a trained one. In conclusion, therefore, it is important to emphasize that the non-skilled trainer finds it difficult to achieve the optimum sport development, the fulfillment of the assigned tasks, the selection, the dosage, the linking of different means, and the assessment of achievement. According to the national sport level, the university trainer＇s profile neither allows the consolidation of practice nor these ages and sport levels.

Computer Technology and Application 2014年第2期5卷 91-97页

作者： Salvador Ibarra Martinez jose Antonio Castan Rocha Julio Laria Menchaca Mayra Guadalupe Trevino Berrones Javier Guzman Obando Julissa Perez Cobos emilio Castan Rocha Computer Science Department Engineering School Autonomous University of Tamaulipas Victoria Tamaulipas 87000 Mexico. Electrical and Electronic Department Technological Institute of Madero City Tampico Tamaulipas 89440 Mexico.

Autonomous navigation is a complex challenge that involves the interpretation and analysis of information about the scenario to facilitate the cognitive processes of a robot to perform free trajectories in dynamic environments. To solve this, the paper introduces a Case-Based Reasoning methodology to endow robots with an efficient decision structure aiming of selecting the best maneuver to avoid collisions. In particular, Manhattan Distance was implemented to perform the retrieval process in CBR method. Four scenarios were depicted to run a set of experiments in order to validate the functionality of the implemented work. Finally, conclusions emphasize the advantages of CBR methodology to perform autonomous navigation in unknown and uncertain environments.
