Abstract: a cross-sectional study was conducted aimed at quantifying the effect that a combination of physical exercises produced over elasticity in sound individuals over 55. 9 healthy subjects that had participated in a plan of aerobic and endurance physical exercises with a mild intensity from monday to friday during 45 min each day for 2 years, were studied. another group composed of 9 sound individuals that had not practiced any exercise during the same period was also studied. both groups took part in a battery of diagnostic tests that included the reading of systolic, diastolic and median arterial pressure. the pulse pressure, the arterial diastolic and systolic diameters, as well as the thickness of the intima-media complex of the right carotid artery were measured by high resolution ultrasound. with these elements, the distensibility, compliance, rigidity index and elastic modulus were calculated. no statistically significant differences were observed between both study groups, in spite of the fact that the group practicing exercises was as an average 7 years older (p < 0.05) and had a thickness of the intima-media complex greater (p < 0.1) than the control group. it was concluded that the plan of phsycial exercises carried out could have produced a reduction of the deterioration of arterial elasticity depending on age

Abstract: Se realizó un estudio de corte transversal con el objetivo de cuantificar el efecto que una combinación de ejercicios físicos producía sobre la elasticidad arterial en sujetos sanos mayores de 55 a os. Se estudiaron 9 sujetos sanos que habían participado en un plan de ejercicios físicos aerobios y de resistencia durante 2 a os y frecuencia diaria de lunes a viernes durante 45 min y con una intensidad ligera. Se estudió igualmente un grupo de 9 sujetos sanos que no habían realizado ejercicio alguno durante el mismo período. Ambos grupos fueron sometidos a una batería de pruebas diagnósticas que incluyó la medición de las presiones arteriales sistólica, diastólica y media; se midió la presión de pulsos y los diámetros arteriales diastólico y sistólico, así como el grosor del complejo íntima-media de la arteria carótida derecha con ultrasonido de alta resolución. Con estos elementos se calculó la distensibilidad, la compliancia, el índice de rigidez y el módulo elástico. No se observaron diferencias estadísticamente significativas entre ambos grupos de estudio, a pesar de que el grupo ejercitado fue como promedio 7 a os más viejo (p<0,05) y tuvo un grosor del complejo íntima-media mayor (p<0,1) que el grupo control. Se concluyó que el plan de ejercicios físicos realizados pudo haber producido un efecto de disminución de la progresión del deterioro de la elasticidad arterial dependiente de la edad A cross-sectional study was conducted aimed at quantifying the effect that a combination of physical exercises produced over elasticity in sound individuals over 55. 9 healthy subjects that had participated in a plan of aerobic and endurance physical exercises with a mild intensity from Monday to Friday during 45 min each day for 2 years, were studied.

Abstract: Angela KAUPP geht in ihrer religionsp dagogischen Dissertation der Frage nach, wie sich Religiosit t in der Lebensgeschichte katholisch sozialisierter junger Frauen entfaltet. Die Kategorien Geschlecht und Religiosit t wurden in der Jugendforschung bislang wenig berücksichtigt. Die lesenswerte Studie schlie t eine Lücke zwischen der p dagogischen, sozialwissenschaftlichen und religionsp dagogischen Forschung. Geschlecht und Religiosit t werden von den befragten Frauen weitgehend als unabh ngig voneinander und von ihrer Lebensgeschichte eingestuft. Von hoher Bedeutung ist die Er ffnung von religi sen Kommunikations- und Beziehungsangeboten sowie authentischer atmosph rischer R ume, z.B. in der Liturgie der Gemeinde. KAUPP zeigt, dass Biographieforschung sich mit einigen Modifikationen als geeignete Methode erweist, die Identit tsentwicklung junger Erwachsener auch im Kontext von Religiosit t und Geschlecht zu erforschen. URN: urn:nbn:de:0114-fqs0701183 In her dissertation on religious pedagogy, Angela KAUPP examines the part played by religiousness in the life stories of young women brought up as Catholics in Germany. The categories of gender and religiousness are still neglected fields in youth studies and KAUPP's readable study closes a gap in research on religious and social-scientific research on pedagogy. The interviewees consider gender and religiousness to be independent and to have few implications for their life stories. They attribute high importance to religious communication, relations and spaces as part of formal and informal religious settings such as the liturgy and prayer groups. KAUPP's work indicates that biographical research is a promising method for the exploration of the development of young adults' identities in the context of religiousness and gender. URN: urn:nbn:de:0114-fqs0701183 En su estudio sobre la pedagogía religiosa, Angela KAUPP examina el papel de lo religioso en Alemania mediante historias de vida de chicas con educación católica. Las categorías de género y religiosidad son campos a menudo olvidados en estudios con jóvenes y el ameno trabajo de KAUPP supera esa brecha en la investigación científico-social de la religiosidad y la pedagogía. Las entrevistadas consideran el género y la religiosidad como algo independiente y que tiene pocas implicaciones en sus vidas. Atribuyen una gran importancia a la comunicación, las relaciones y los espacios religiosos como una parte más de las convenciones religiosas, como la liturgia y las agrupaciones. El trabajo de KAUPP muestra que la investigación biográfica es un método promete

Abstract: Expressions of the Personalization of Leadership: Perspectives of Slovak Party Leaders in Relation to their media Coverage. This study examines the impact and position of party leaders in relation to the personalization of politics in the Slovak Republic. It identifies personalization in the media, expressed by an increase in the focus of media coverage on individual politicians. The main objective is to show the nature and presentation of party leaders in relation to the concept of personalization, as well as in relation to the type of presentation (negative, positive, or neutral). The study is based on the common finding that if the political party has a dominant and stable position within the system and the party leader has a strong and charismatic personal characteristic (valence), her or she is presented through positive or neutral messages rather than negative, and vice versa.

Abstract: The assembly of the mitotic centromere has been extensively studied in recent years, revealing the sequence and regulation of protein loading to this chromosome domain. However, few studies have analyzed centromere assembly during mammalian meiosis. This study specifically targets this approach on mouse spermatocytes. We have found that during prophase I, the proteins of the chromosomal passenger complex Borealin, INCENP, and Aurora-B load sequentially to the inner centromere before Shugoshin 2 and MCAK. The last proteins to be assembled are the outer kinetochore proteins BubR1 and CENP-E. All these proteins are not detected at the centromere during anaphase/telophase I and are then reloaded during interkinesis. The loading sequence of the analyzed proteins is similar during prophase I and interkinesis. These findings demonstrate that the interkinesis stage, regularly overlooked, is essential for centromere and kinetochore maturation and reorganization previous to the second meiotic division. We also demonstrate that Shugoshin 2 is necessary for the loading of MCAK at the inner centromere, but is dispensable for the loading of the outer kinetochore proteins BubR1 and CENP-E.

Abstract: In most eutherian mammals, sex chromosomes synapse and recombine during male meiosis in a small region called pseudoautosomal region. However in some species sex chromosomes do not synapse, and how these chromosomes manage to ensure their proper segregation is under discussion. Here we present a study of the meiotic structure and behavior of sex chromosomes in one of these species, the Mongolian gerbil (Meriones unguiculatus). We have analyzed the location of synaptonemal complex (SC) proteins SYCP1 and SYCP3, as well as three proteins involved in the process of meiotic recombination (RAD51, MLH1, and γ-H2AX). Our results show that although X and Y chromosomes are associated at pachytene and form a sex body, their axial elements (AEs) do not contact, and they never assemble a SC central element. Furthermore, MLH1 is not detected on the AEs of the sex chromosomes, indicating the absence of reciprocal recombination. At diplotene the organization of sex chromosomes changes strikingly, their AEs associate end to end, and SYCP3 forms an intricate network that occupies the Y chromosome and the distal region of the X chromosome long arm. Both the association of sex chromosomes and the SYCP3 structure are maintained until metaphase I. In anaphase I sex chromosomes migrate to opposite poles, but SYCP3 filaments connecting both chromosomes are observed. Hence, one can assume that SYCP3 modifications detected from diplotene onwards are correlated with the maintenance of sex chromosome association. These results demonstrate that some components of the SC may participate in the segregation of achiasmate sex chromosomes in eutherian mammals.
