Assessment of fibronectin as a potential new clinical tool in andrology.

In this prospective clinical study, 892 patients with normal and impaired semen were examined in order to investigate the correlation between the concentration of fibronectin in seminal plasma and the motility of spermatozoa. The fibronectin concentration in seminal plasma, total sperm motility and linear sperm motility were measured. We report here a significant negative correlation between the fibronectin concentration in seminal plasma and total sperm motility (r=-0.3474). There was no link between varicocele and vasectomy, or between varicocele and variation in the concentration of fibronectin. It is concluded that higher concentrations of the acute-phase protein fibronectin may be a cause of severe reduction in sperm motility. The investigation of fibronectin concentrations in seminal fluid could be a new and helpful clinical tool in the assessment of male fertility.

Art as an educative and social tool

Since remote times, certain sectors of society have been exposed to inequality and vulnerability, where adequate intervention processes have become conspicuous because of their absence. Nowadays, current societies have the responsibility of contributing, based on their experience and knowledge, with more efficient policies and programs that improve the life quality of the most disadvantaged. It is here where art and its different tools play a very important role, not only on a physical level, but also as an education tool that allows the development of emotional, mental and communicative skills. The aim of this paper is to make clear the potential of art as an instrument of social and educational intervention. It starts by showing worldwide-collected experience related to education and arts, and then, it acquaints the reader with two parallel intervention projects that worked with youths under social vulnerability conditions. These interventions were developed based on a qualitative research (Grounded theory), using as methodology “The Artistic Mediation” with emphasis on body language. This methodology helped researchers to get close to the participants and to know their experiences and emotions. At the same time, it was possible to evidence the positive effects of educative interventions through art. These workshops were based on an artistic methodology especially focused on body language. Data in this work is qualitative, and as such, it permits a special approach to the personal and emotional experiences of the participants; clearly showing the positive effects of the referenced practice on them.
