Abstract: this research project analyzes the importance of effective conflict management among persons. they become part of an emotional and experiential repertory for the individual and, on occasion, they suppose dysfunction in interpersonal relations, even when they do not always lead to aggression; there will be cases that deal with incompatibility among the parties due to their interests, engendering distancing or violence between them. effective conflict management demands skills for which mediation through implementation of a bioethical-hermeneutic model is offered to achieve both the agreement and recognition of the other party as a legitimate other, reinforcing the quality of peoples? lives. this is a descriptive documentary type of investigation and descriptive observation and content analysis were used to collect data. from the results, it can be concluded that valuation and recognition as such of the people in conflict represents an alternative for guaranteeing a rapid and secure solution with beneficial and lasting agreements.

Abstract: Algunas habilidades prelectoras pueden preparar al ni o para un desempe o lector exitoso. A su vez, la existencia de un contexto alfabetizador familiar favorece la adquisición de estas habilidades prelectoras. El objetivo de este trabajo fue explorar las relaciones entre contexto alfabetizador familiar y adquisición de habilidades prelectoras, así como el estudio de las relaciones entre estas habilidades y el desempe o posterior de la lectura. Para ello se seleccionó una muestra de 52 participantes de 5 a os de edad, de clase social media y a los padres o tutores de los ni os y ni as. Se aplicó un cuestionario para explorar el contexto alfabetizador familiar a los padres o tutores, una evaluación de habilidades prelectoras mediante la prueba “Prepárate a leer” y una evaluación de procesos lectores a los mismos ni os (PROLEC) en el primer curso de educación primaria. Los resultados muestran asociaciones entre el nivel educativo de los padres y la adquisición de habilidades prelectores, así como entre estas y el desempe o lector. La variable con mayor poder explicativo en el desempe o lector fue la conciencia fonológica. There are pre-reading skills that are able to prepare students for successful reading. At the same time a literacy family context would be improve early reading acquisition. The main goal of this study was to explore the relationship between the literacy family context and early pre-reading skills acquisitions. Other target was study the pre-reading skills and reading performance interaction. 52 kindergarten children, 5 years old, and from a middle social class were used in this study. Their parents were interviewed with a specific questionnaire made for this research in order to know the literacy family context. Participants’ pre-reading skills were also assessed by the Spanish version of Get Ready to Read! Screening Tool. And the Spanish version of Reading Processes Assessment Test (PROLEG) was used for reading processes assessment when participants got the first grade. Results show statistically significant relations among parent’s education degree and children’s pre-reading skills. Significant correlations between reading performance and children’s pre-reading skills were also found. The main prediction variable for reading performance was phonological awareness.

Abstract: Telomere length and telomerase activity are important factors in the pathobiology of human diseases. Age-related diseases and premature aging syndromes are characterized by short telomeres, which can compromise cell viability, whereas tumour cells can prevent telomere loss by aberrantly upregulating telomerase. The zebrafish (Danio rerio) offers multiple experimental manipulation advantages over other vertebrate models and, therefore, it has been recently considered as a potential model for aging, cancer, and regeneration studies. However, it has only partially been exploited to shed light on these fundamental biological processes. The aim of this study was, therefore, to investigate telomere length and telomerase expression and activity in different strains of zebrafish obtained from different stock centres to determine whether they undergo any changes during aging and regeneration. We found that although both telomerase expression and telomere length increased from embryo to adulthood stages, they drastically declined in aged fish despite telomerase activity was detected in different tissues of old fish. In addition, we observed a weaker upregulation of telomerase expression in regenerating fins of old fish, which well correlates with their impaired regeneration capacity. Strikingly, telomeres were elongated or maintained during the fin regeneration process at all ages and after repeated amputations, likely to support high cell proliferation rates. We conclude that the expression of telomerase and telomere length are closely related during the entire life cycle of the fish and that these two parameters can be used as biomarkers of aging in zebrafish. Our results also reveal a direct relationship between the expression of telomerase, telomere length and the efficiency of tissue regeneration.

Abstract: Biotransformation processes have been successfully utilized to obtain products of pharmaceutical, chemical, food, and agricultural interest, which are difficult to obtain by classic chemical methods. The compound with antituberculous activity, 9-methoxy-tariacuripyrone (1), isolated from Aristolochia brevipes, was submitted to biotransformation with the yeast Saccharomyces cerevisiae under culture, yielding 5-amino-9-methoxy-3,4-dihydro-2H-benzo[h]chromen-2-one (2). The structure of 2 was elucidated on the basis of spectroscopic analyses. The results mainly show the reduction of the double bond and the nitro group of compound 1. Metabolite 2 demonstrated an increase in anti-tuberculous activity (MIC = 3.12 μg/mL) against the drug-sensitive Mycobacterium tuberculosis (H37Rv) strain, with respect to that shown by 1.

Abstract: it has been demonstrated that food deprivation and access to food are common variables in studies about experimental analysis of feeding behavior and motivational theory. it is unknown if the order of exposure of these variables can modify intake patterns. the present study explores, the effect between food deprivation and access-duration to food was explored. the aim of this study was to explore the effects of food deprivation and food access-duration on food intake in rats. the experimental design included exposure, in ascending and descending order, to both variables. twelve female rats were assigned to one of each of the four groups: long ascending, long descending, short ascending and short descending. it was found that food intake was greater in short groups, independently of the order of exposure. the corporal weight followed the same tendency as the food intake under all conditions. these results are being discussed in terms of their possible implication for the development of excessive or deficit food-intake patterns. to generalize these results it is necessary to have more studies that take account of different combinations of both variables, as well as male rats as subjects.
