Fusion cross sections were measured for the exotic proton-halo nucleus (8)B incident on a (58)Ni target at several energies near the Coulomb barrier. This is the first experiment to report on the fusion of a protonhalo nucleus. The resulting excitation function shows a striking enhancement with respect to expectations for normal projectiles. Evidence is presented that the sum of the fusion and breakup yields saturates the total reaction cross section.

Elastic scattering of (8)B, (7)Be, and (6)Li on a (58)Ni target has been measured at energies near the Coulomb barrier. Optical-model fits were made to the experimental angular distributions, and total reaction cross sections were deduced. A comparison with other systems provides striking evidence for proton-halo effects on (8)B reactions. As opposed to the situation for the neutron-halo nucleus (6)He, for which particle transfer dominates, the ""extra"" cross section observed for (8)B appears to result entirely from projectile breakup.

The recently discovered cyclotides kalata B1 and kalata B2 are miniproteins containing a head-to-tail cyclized backbone and a cystine knot motif, in which disulfide bonds and the connecting backbone segments form a ring that is penetrated by the third disulfide bond. This arrangement renders the cyclotides extremely stable against thermal and enzymatic decay, making them a possible template onto which functionalities can be grafted.We have compared the hydrodynamic properties of two prototypic cyclotides, kalata B1 and kalata B2, using analytical ultracentrifugation techniques. Direct evidence for oligomerization of kalata B2 was shown by sedimentation velocity experiments in which a method for determining size distribution of polydisperse molecules in solution was employed. The shape of the oligomers appears to be spherical. Both sedimentation velocity and equilibrium experiments indicate that in phosphate buffer kalata B1 exists mainly as a monomer, even at millimolar concentrations. In contrast, at 1.6 mM, kalata B2 exists as an equilibrium mixture of monomer (30%), tetramer (42%), octamer (25%), and possibly a small proportion of higher oligomers. The results from the sedimentation equilibrium experiments show that this self-association is concentration dependent and reversible. We link our findings to the three-dimensional structures of both cyclotides, and propose two putative interaction interfaces on opposite sides of the kalata B2 molecule, one involving a hydrophobic interaction with the Phe(6), and the second involving a charge-charge interaction with the Asp(25) residue. An understanding of the factors affecting solution aggregation is of vital importance for future pharmaceutical application of these molecules.

The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.

Los cambio provocados por las Técnicas de Reproducción Asistida en materia de filiación nos llevan a pensar que los criterios decisivos para la disciplina de la filiación (por naturaleza) han cambiado a compás de las mutaciones de la conciencia social. En este trabajo procuraré demostrar cómo la voluntad ha pasado a ser el elemento decisivo en la determinación de la maternidad y/o paternidad a partir del surgimiento y utilización de las Técnicas de Reproducción Asistida.

Este trabajo tiene por objeto el estudio y análisis del acceso al aborto legal y seguro como esencial para el disfrute y efectivo ejercicio de los derechos humanos de las mujeres.Procuraré demostrar cómo el acceso al aborto seguro y legal es un elemento central para el cumplimiento de los derechos humanos de las mujeres en términos generales, incluyendo sus derechos reproductivos y aquellos relacionados a su inherente condición de persona, y cómo su penalización y demás restricciones de acceso, importan una violación de estos derechos humanos.Consecuentemente, más que de un "derecho al aborto" en sentido estricto, de lo que procuro hablar es de la concreción de los derechos a la libertad, la intimidad, la dignidad y el libre desarrollo de la personalidad, dado que, las decisiones de las mujeres en materia de aborto no tienen que ver solamente con sus cuerpos en términos abstractos, sino que, en términos másamplios, se encuentran relacionadas con sus derechos humanos inherentes a su condición de persona, a su dignidad y privacidad. Para su mejor entendimiento y desarrollo, dividiré el trabajo en 4 capítulos.El primer capítulo se dedicará al estudio y análisis de los aspectos legales del aborto: su contemplación en el marco de la Naciones Unidas, en el Consejo de Europa y en la Unión Europea. También se detallarán y explicaránlos diversos sistemas de regulación del aborto contemplados por las diferenteslegislaciones nacionales.En el segundo capítulo se analizará la problemática concerniente al aborto, realizando especial hincapié en sus causas y consecuencias; y se examinarán los principales argumentos de porqué no es útil la penalización del aborto.En el tercer capítulo abordaré, específicamente, porqué la penalización y las restricciones de acceso a un aborto legal y seguro importan una violación de los derechos humanos de las mujeres. Y en el cuarto capítulo efectuaré un análisis jurisprudencial de las principales sentencias del Tribunal Europeo de Derechos Humanos. Por último expondré mis conclusiones.
