Analysis of the multi-copy gene family FAM90A as a copy number variant in different ethnic backgrounds

Copy number variants contribute extensively to inter-individual genomic differences, but little is known about their inter-population variability and diversity. In a previous study (Bosch et al., 2007; 16:2572-2582), we reported that the primate-specific gene family FAM90A, which accounts for as many as 25 members in the human reference assembly, has expanded the number of FAM90A clusters across the hominoid lineage. Here we examined the copy number variability of FAM90A genes in 260 HapMap samples of European, African, and Asian ancestry, and showed significant inter-population differences (p<0.0001). Based on the recent study of Stranger et al. (2007; 315:848-853), we also explored the correlation between copy number variability and expression levels of the FAM90A gene family. Despite the high genomic variability, we found a low correlation between FAM90A copy number and expression levels, which could be due to the action of independent trans-acting factors. Our results show that FAM90A is highly variable in copy number between individuals and between populations. However, this variability has little impact on gene expression levels, thus highlighting the importance of genomic variability for genes located in regions containing segmental duplications.

Introduction to University and the ICT Sector

The innovative subject “Introduction to ICT” combines a general Introductory Course to the University with elements around the Information and Communication Technologies sector (including the ICT engineer competence profile, market aspects, etc.)This new course has been developed and implemented in three degree programmes offered by the Polytechnic School at Universitat Pompeu Fabra, Barcelona. The course team consists of thirteen teachers,including business professionals, librarians, computer technicians, institutional representatives as well as an educationalist responsible for advising on methodology and study techniques. The subject was designed for a high number of students (260). At the end of the course, we collected quantitative and qualitativeinformation about the students’ satisfaction. The findings show the positive vision that they had about the topics worked during the subject. This paper describes the course, its implementation and evaluation and, of course, the details of the findings that we collected about students' satisfaction.

Women's employment and the adult caring burden

Demographic ageing is increasing pensions, health and social services spending and threatening the future balance of public budgets. Providing home care can help to curb health expenditure and it may improve elderly welfare also, but EU states have chosen different policies in providing home are. Main differences are related with source of financing and eligibility criteria but also with the kind of benefits (benefits in cash or in kind). How these different options affect welfare and carers’ employment opportunities is the core of this research. Home care growth is going to be more efficient as far as it pro motes employment and, public revenues consequently. Using microdata from the European Community Household Panel, British and Spanish means tested programs are compared with German and Austrian ‘in cash’ benefits, and with Danish ‘in kind’ benefits also. The results show that Danish policies are the most efficient and equitable while the British and Spanish ones are the worst.

Influence of average size and interface passivation on the spectral emission of Si nanocrystals embedded in SiO2

The correlation between the structural (average size and density) and optoelectronic properties [band gap and photoluminescence (PL)] of Si nanocrystals embedded in SiO2 is among the essential factors in understanding their emission mechanism. This correlation has been difficult to establish in the past due to the lack of reliable methods for measuring the size distribution of nanocrystals from electron microscopy, mainly because of the insufficient contrast between Si and SiO2. With this aim, we have recently developed a successful method for imaging Si nanocrystals in SiO2 matrices. This is done by using high-resolution electron microscopy in conjunction with conventional electron microscopy in dark field conditions. Then, by varying the time of annealing in a large time scale we have been able to track the nucleation, pure growth, and ripening stages of the nanocrystal population. The nucleation and pure growth stages are almost completed after a few minutes of annealing time at 1100°C in N2 and afterward the ensemble undergoes an asymptotic ripening process. In contrast, the PL intensity steadily increases and reaches saturation after 3-4 h of annealing at 1100°C. Forming gas postannealing considerably enhances the PL intensity but only for samples annealed previously in less time than that needed for PL saturation. The effects of forming gas are reversible and do not modify the spectral shape of the PL emission. The PL intensity shows at all times an inverse correlation with the amount of Pb paramagnetic centers at the Si-SiO2 nanocrystal-matrix interfaces, which have been measured by electron spin resonance. Consequently, the Pb centers or other centers associated with them are interfacial nonradiative channels for recombination and the emission yield largely depends on the interface passivation. We have correlated as well the average size of the nanocrystals with their optical band gap and PL emission energy. The band gap and emission energy shift to the blue as the nanocrystal size shrinks, in agreement with models based on quantum confinement. As a main result, we have found that the Stokes shift is independent of the average size of nanocrystals and has a constant value of 0.26±0.03 eV, which is almost twice the energy of the Si¿O vibration. This finding suggests that among the possible channels for radiative recombination, the dominant one for Si nanocrystals embedded in SiO2 is a fundamental transition spatially located at the Si¿SiO2 interface with the assistance of a local Si-O vibration.

Ni-Mn-Ga thin films produced by pulsed laser deposition

Polycrystalline Ni-Mn-Ga thin films have been deposited by the pulsed laser deposition (PLD) technique, using slices of a Ni-Mn-Ga single crystal as targets and onto Si (100) substrates at temperatures ranging from 673 K up to 973 K. Off-stoichiometry thin films were deposited at a base pressure of 1×10-6-Torr or in a 5 mTorr Ar atmosphere. Samples deposited in vacuum and temperatures above 823 K are magnetic at room temperature and show the austenitic {220} reflection in their x-ray diffraction patterns. The temperature dependences of both electrical resistance and magnetic susceptibility suggest that these samples exhibit a structural martensitic transition at around 260 K. The magnetoresistance ratio at low temperature can be as high as 1.3%, suggesting the existence of a granular structure in the films

El examen MIR y su contenido en anatomía humana, bioestadística y epidemiología: evolución y accesibilidad para el opositor/a

Fundamentos: El examen MIR constituye actualmente el único medio de selección de candidatos para la formación de médicos especialistas en España. Consta de 260 preguntas (10 de ellas son de reserva) de las distintas asignaturas de la licenciatura de medicina. El presente estudio pretende describir la evolución de los contenidos en anatomía humana, bioestadístíca y epidemiología de las distintas convocatorias MIR realizadas desde 1982. Métodos: Se analizaron todos los exámenes MIR generales desde 1982 hasta 1996, incluidas las convocatorias específicas de medicina familiar y comunitaria desde 1995 a 1997. En cada examen, se identificaron los contenidos de todas las preguntas relacionadas con anatomía humana, bioestadistica y epidemiología, según una clasificación en categorías temáticas adaptada de los programas docentes de cada asignatura. El tratamiento estadístico consistió en el análisis descriptivo (tabulación y representación gráfica) de las categorías temáticas y de su accesibilidad para un hipotético opositor/a con unos determinados conocimientos. Resultados: El número de preguntas de cada una de dichas asignaturas no superó en ninguna convocatoria general el 4% del total de preguntas. Las categorías temáticas con mayor frecuencia de aparición fueron, en anatomía humana, extremidad superior e inferior; en bioestadística, probabilidad/pruebas diagnósticas, y epidemiología descriptiva para el caso de epidemiología. Un hipotético opositor/a que no se preparó ningún tema de anatomía humana, bioestadística o epidemiología tan sólo tuvo acceso, respectivamente, a 1, 6 o 3 de las 15 convocatorias generales MIR revisadas. Conclusiones: En el examen MIR, la presencia de contenidos de anatomía humana tiende a disminuir, mientras que los de bioestadística y epidemiología cobran mayor importancia. Un/a opositor/a que domine los conocimientos adquiridos durante su licenciatura tiene acceso temático a la totalidad de preguntas de dichas asignaturas.

Spermiogenesis and spermatozoon of the liver fluke Mediogonimus jourdanei (Microphalloidea: Prosthogonimidae), a parasite of Myodes glareolus (Rodentia: Cricetidae)

Spermatological characters of the liver fluke Mediogonimus jourdanei Mas-Coma et Rocamora, 1978 were studied by means of transmission and scanning electron microscopy. Spermiogenesis begins with the formation of the differentiation zone containing two centrioles associated with striated rootlets and an intercentriolar body. These two centrioles originate two free flagella that undergo a 90 degrees rotation before fusing with the median cytoplasmic process. Both nuclear and mitochondrial migrations toward the median cytoplasmic process occur before the proximodistal fusion of flagella. Finally, the constriction of the ring of arched membranes gives rise to the young spermatozoon. The mature sperm of M. jourdanei measures about 260 microm and presents two axonemes of different lengths with the typical pattern of the Trepaxonemata, two bundles of parallel cortical microtubules, one mitochondrion, a nucleus and granules of glycogen. An analysis of all the microphalloidean species studied to date emphasised some differences in certain characters found in Maritrema linguilla Jägerskiöld, 1908 and Ganeo tigrinum Mehra et Negi, 1928 in comparison to those in the remaining microphalloideans. The presence and variability of such ultrastructural characters according to family, superfamily or order have led several authors to propose their use in the analysis of trematode relationships and phylogeny. Therefore, apart from producing new data on the family Prosthogonimidae, the present study also compares the spermatological organization of M jourdanei with other available ultrastructural studies focusing on the Microphalloidea.

La competitividad exterior de las pymes y las grandes empresas industriales españolas

El objetivo de este trabajo es analizar, mediante la técnica multicriterio, cómo ha evolucionado la competitividad de los sectores de la industria manufacturera española en el periodo 1991-2001. El análisis se realiza diferenciando entre pymes y grandes empresas y no se focaliza en la competitividad-precio, sino que adopta un enfoque más amplio en el que se incorporan aspectos estructurales. Los resultados permiten afirmar en primer lugar, que en la década de estudio, no se han producido cambios de gran envergadura en los perfiles competitivos de los sectores industriales españoles. En segundo lugar, que los perfiles competitivos difieren según hablemos de pymes o grandes empresas. Y en tercer lugar, que uno de los factores que siguen siendo más determinantes de la posición competitiva de los sectores industriales es la innovación.
