El VIH: el origen, la patología y el tratamiento

The HIV (Human Immunodeficiency Virus) is a very important disease in the world, with approximately 35 million people infected. In this study we have tried to expose the main characters of the virus, explaining the disease and the illness associated to the HIV. Besides, we have explained the antiretroviral treatments that are the most important weapon against the HIV. However, any of these treatments do not eliminate the HIV in the human body. For this reason, we have been looking for the new treatments and researches that have been development in the last years, including vaccines and genetic resistance. In addition, we have described the situation of the SIV (Simian Immunodeficiency Virus) in Africa, because it is the origin of the disease. The prevalence of the virus in primates population is something that have being studied for the last years, because it could be a new threat to the human population. Finally, we have proposed the researches lines that seems to be more effective and the ones that, in a future, could eliminate the virus in the human body.

Inplante kirurgiko erradiopakoen bideragarritasuna: plla/bario sulfato sistemaren ``in vitro´´ degradazioa.

[EU]Polimero biobateragarri eta biodegradagarrien erabilera medikuntza arloan aurrerapauso handia suposatu du. Inplanteen arloan (torlojuak, iltzeak, plakak, eta abar…) eta ehun ingeniaritzan garrantzia handia dute. Hala ere, polimero hauen inplanteek desabantaila nabaria aurkezten dute ohiko material metalikoekin alderatuz: erradiopazitate eza. Ikerketa lan honetan karga erradiopako baten adizioak polimero biobateragarri eta biodegradagarri baten giza gorputzaren baldintzetan (pH=7,2 eta 37ºC) burututako in vitro degradazioan duen eragina aztertu da, %70 poli(L-laktida) (PLLA) eta %30 bario sulfato (BaSO4) sistemaren degradazioa, hain zuzen ere. Aztertutako karga erradiopakoak PLLAren degradazioan eragin handirik ez duela ondorioztatu da, beraz, sistema bideragarria dela.

El ciudadano al desnudo y los seres encubiertos en la antigua Grecia

[EN] Considerando el celebérrimo desnudo masculino heleno, el presente trabajo investiga las coordenadas del imaginario griego que dieron lugar a esta rompedora «puesta en escena» del cuerpo humano e investiga la yuxtaposición vestido/desnudo como un principio diferenciador de primera magnitud en el proceso formativo de las categorías de Ciudadano, Mujer y Bárbaro.

Body image and body composition: comparisons of young male elite soccer players and controls

[EN] The purpose of this study was to evaluate body composition and body image (perception and satisfaction) in a group of young elite soccer players and to compare the data with those of a control group (age and BMI matched). Participants were 56 volunteer males whose mean age and BMI were 19.6 (SD 1.3) years and 23.3 (SD 1.1) kg/m2, respectively. Results showed that soccer players have a higher lean mass and lower fat mass than controls. Moreover, body perception (difference between current and actual image) was more accurate in controls than in soccer players, and the results suggest a tendency for soccer players to aspire to have more muscle mass and body fat. Soccer players perceived an ideal image with significantly higher body-fat percentage than their current and actual images. There were no body-dissatisfaction differences between groups, however. Although the results are necessarily limited by the small sample size, the findings should be of interest to coaches of young elite soccer teams.

The body social: an enactive approach to the self

This paper takes a new look at an old question: what is the human self? It offers a proposal for theorizing the self from an enactive perspective as an autonomous system that is constituted through interpersonal relations. It addresses a prevalent issue in the philosophy of cognitive science: the body-social problem. Embodied and social approaches to cognitive identity are in mutual tension. On the one hand, embodied cognitive science risks a new form of methodological individualism, implying a dichotomy not between the outside world of objects and the brain-bound individual but rather between body-bound individuals and the outside social world. On the other hand, approaches that emphasize the constitutive relevance of social interaction processes for cognitive identity run the risk of losing the individual in the interaction dynamics and of downplaying the role of embodiment. This paper adopts a middle way and outlines an enactive approach to individuation that is neither individualistic nor disembodied but integrates both approaches. Elaborating on Jonas' notion of needful freedom it outlines an enactive proposal to understanding the self as co-generated in interactions and relations with others. I argue that the human self is a social existence that is organized in terms of a back and forth between social distinction and participation processes. On this view, the body, rather than being identical with the social self, becomes its mediator
