Human papillomavirus detection in women with and without human immunodeficiency virus infection in Colombia

Background: HIV infection leads to a decreasing immune response, thereby facilitating the appearance of other infections, one of the most important ones being HPV. However, studies are needed for determining associations between immunodeficiency caused by HIV and/or the presence of HPV during the course of cervical lesions and their degree of malignancy. This study describes the cytological findings revealed by the Papanicolaou test, laboratory characteristics and HPV molecular profile in women with and without HIV infection. Methods: A total of 216 HIV-positive and 1,159 HIV-negative women were invited to participate in the study; PCR was used for the molecular detection of HPV in cervical samples. Statistical analysis (such as percentages, Chi-square test and Fisher's exact test when applicable) determined human papillomavirus (HPV) infection frequency (single and multiple) and the distribution of six types of high-risk-HPV in women with and without HIV infection. Likewise, a logistic regression model was run to evaluate the relationship between HIV-HPV infection and different risk factors. Results: An association was found between the frequency of HPV infection and infection involving 2 or more HPV types (also known as multiple HPV infection) in HIV-positive women (69.0% and 54.2%, respectively); such frequency was greater than that found in HIV-negative women (44.3% and 22.7%, respectively). Statistically significant differences were observed between both groups (p = 0.001) regarding HPV presence (both in infection and multiple HPV infection). HPV-16 was the most prevalent type in the population being studied (p = 0.001); other viral types had variable distribution in both groups (HIV-positive and HIV-negative). HPV detection was associated with <500 cell/mm(3) CD4-count (p = 0.004) and higher HIV-viral-load (p = 0.001). HPV-DNA detection, <200 cell/mm(3) CD4-count (p = 0.001), and higher HIV-viral-load (p = 0.001) were associated with abnormal cytological findings. Conclusions: The HIV-1 positive population in this study had high multiple HPV infection prevalence. The results for this population group also suggested a greater association between HPV-DNA presence and cytological findings. HPV detection, together with low CD4 count, could represent useful tools for identifying HIV-positive women at risk of developing cervical lesions.

Das Bistum Münster 10. Das Augustinerchorherrenstift Bernried

Das Augustinerchorherrenstift Bernried ist eine Gründung des 12. Jahrhunderts und beheimatete bis zur Säkularisation 1803 einen Augustinerchorherrenkonvent. Die Stiftung des Grafenpaares Otto und Adelheid von Valley gehörte zu den neuen geistlichen Niederlassungen, die im Zuge der Reformbewegung der Regularkanoniker fundiert wurden. Für die Region um Bernried am Starnberger See wirkte das Stift als gestalterische Kraft über sechs Jahrhunderte hinweg. Großen Aufschwung nahm das Stift erneut im 18. Jahrhundert, als herausragende Pröpste gerade die musikalische Entwicklung des Konventes förderten: einige Pröpste wirkten als Komponisten; von den Musikalien haben sich zahlreiche Handschriften und Instrumente erhalten. Nach dem bewährten Schema der Germania Sacra skizziert die Autorin Walburga Scherbaum kenntnisreich die Geschichte, die Verfassung, das geistige und religiöse Leben, die Besitzgeschichte und vor allem das Personal des Stiftes von seiner Gründung bis zur Aufhebung. Mit diesem Werk werden die Bemühungen der Germania Sacra um die geistlichen Institutionen im Alten Reich um eine weitere geistliche Niederlassung im bayerischen Raum neben Raitenhaslach (Germania Sacra N. F. 11), Dietramszell (Germania Sacra N. F. 24), Benediktbeuern (Germania Sacra N. F. 28) und Wessobrunn (Germania Sacra N. F. 39) bereichert.

Genetic deficiency of C4, C2 or C1q and lupus syndromes. Association with anti-Ro (SS-A) antibodies

Individuals with mutations in XPNPEP3, which encodes a mitochondrial protein, develop a nephronophthisis-like nephropathy.

The autosomal recessive kidney disease nephronophthisis (NPHP) constitutes the most frequent genetic cause of terminal renal failure in the first 3 decades of life. Ten causative genes (NPHP1-NPHP9 and NPHP11), whose products localize to the primary cilia-centrosome complex, support the unifying concept that cystic kidney diseases are "ciliopathies". Using genome-wide homozygosity mapping, we report here what we believe to be a new locus (NPHP-like 1 [NPHPL1]) for an NPHP-like nephropathy. In 2 families with an NPHP-like phenotype, we detected homozygous frameshift and splice-site mutations, respectively, in the X-prolyl aminopeptidase 3 (XPNPEP3) gene. In contrast to all known NPHP proteins, XPNPEP3 localizes to mitochondria of renal cells. However, in vivo analyses also revealed a likely cilia-related function; suppression of zebrafish xpnpep3 phenocopied the developmental phenotypes of ciliopathy morphants, and this effect was rescued by human XPNPEP3 that was devoid of a mitochondrial localization signal. Consistent with a role for XPNPEP3 in ciliary function, several ciliary cystogenic proteins were found to be XPNPEP3 substrates, for which resistance to N-terminal proline cleavage resulted in attenuated protein function in vivo in zebrafish. Our data highlight an emerging link between mitochondria and ciliary dysfunction, and suggest that further understanding the enzymatic activity and substrates of XPNPEP3 will illuminate novel cystogenic pathways.

Unterstützungssysteme im Kontext von Regionalisierungsprozessen. Eine theoretische und empirische Annäherung

In Fragen der Schulentwicklung allgemein, aber auch im Zuge der aktuellen Regionalisierungstendenzen im Schul- und Bildungswesen, wird Unterstützungssystemen für die Einzelschule eine wachsende Bedeutung zugeschrieben. Dennoch finden sich bislang erst wenige Arbeiten im Diskurs, die Unterstützungssysteme im Zusammenhang mit Regionalisierungsprozessen beleuchten und robuste Analyseinstrumente vorstellen, mit deren Hilfe Unterstützung im Zusammenhang von Regionalisierung gefasst werden kann. Dieses Desiderat wird im vorliegenden Beitrag aufgegriffen, indem unter anderem auf Grundlage von governance- sowie motivationstheoretischen Überlegungen Kategorien für eine Heuristik erarbeitet werden, die es erlauben, Unterstützungssysteme allgemein und im Kontext von Schul- und Bildungslandschaften entlang verschiedener Dimensionen zu betrachten. Mittels Interviews, die im Rahmen des Projektes ,Schulen im Team – Übergänge gemeinsam gestalten‘ durchgeführt wurden, wird die Heuristik auf den Forschungskontext zu Regionalen Bildungsbüros inhaltsanalytisch angewendet. Erste Befunde weisen darauf hin, dass sich die Heuristik zur Untersuchung von Unterstützungssystemen für einen regionalen Kontext plausibilisieren lässt. (DIPF/Orig.)

Measurement and interpretation of the mid-infrared properties of single crystal and polycrystalline gold

The contribution of electron-phonon scattering and grain boundary scattering to the mid-IR (lambda = 3.392 mum) properties of An has been assessed by examining both bulk, single crystal samples-Au(1 1 1) and Au(1 1 0)-and thin film, polycrystalline An samples at 300 K and 100 K by means of surface plasmon polariton excitation. The investigation constitutes a stringent test for the in-vacuo Otto-configuration prism coupler used to perform the measurements, illustrating its strengths and limitations. Analysis of the optical response is guided by a physically based interpretation of the Drude model. Relative to the reference case of single crystal Au at 100 K (epsilon = - 568 + i17.5), raising the temperature to 300 K causes increased electron-phonon scattering that accounts for a reduction of similar to40 nm in the electron mean free path. Comparison of a polycrystalline sample to the reference case determines a mean free path due to grain boundary scattering of similar to 17 nm, corresponding to about half the mean grain size as determined from atomic force microscopy and indicating a high reflectance coefficient for the An grain boundaries. An analysis combining consideration of grain boundary scattering and the inclusion of a small percentage of voids in the polycrystalline film by means of an effective medium model indicates a value for the grain boundary reflection coefficient in the range 0.55-0.71.

Estudio sobre la eficacia del régimen fiscal cooperativo portugués

El ordenamiento jurídico portugués consagra un régimen fiscal especial para el sector cooperativo, basado, al igual que otros ordenamientos como el español o el italiano, en la protección de la mutualidad como forma de organización empresarial especialmente benéfica en el plano social. Para alcanzar ese objetivo, el régimen fiscal cooperativo debe ser selectivo, lo que significa que al legislador se le plantea el reto de establecer criterios para separar, dentro del marco cooperativo, lo que debe ser protegido de lo que no merece protección fiscal. El legislador portugués optó por un modelo basado en dos grupos de ramos cooperativos claramente diferenciados según los beneficios fiscales aplicables, ambos con amplias exenciones fiscales. El presente trabajo no se centra en el contenido de los beneficios aplicables sino en las condiciones que las cooperativas deben reunir para acogerse a esos regímenes fiscales favorables. Estos criterios son: i) una división entre operaciones con socios y operaciones con terceros; ii) una delimitación de las operaciones o actividades cooperativas según estén o no vinculadas con el “fin propio de la cooperativa”; y iii) una estructura prevalentemente mutualista del factor trabajo. Esta fórmula legal tiene su raíz en una legislación de 1929 y se ha mantenido hasta el día de hoy debido en parte a un fenómeno de inercia legislativa. El presente trabajo, basándose en la metodología de la sociología jurídica, asienta en una encuesta dirigida a 64 cooperativas, por la que se buscaba indagar hasta qué punto estos criterios (de acuerdo con los que se seleccionan las cooperativas que pueden acogerse a los regímenes fiscales favorables) cuadran con la realidad cooperativa actual. Como era de esperar, la vetustez del régimen hizo que se encontraran desajustes muy significativos, que reclaman una reforma urgente.

Mid-infrared a-b plane response of YBa2Cu3O7-delta as a function of doping and temperature determined by attenuated total reflection

The mid-infrared optical response of c-axis thin films of YBa2Cu3O7-delta has been studied using Otto-configuration attenuated total reflectance. The measured reflectance-angle characteristics are dominated by a strong absorption feature due to the excitation of surface plasmons, and can be modeled to determine the a-b plane dielectric function. The results show that while epsilon(i,) and therefore sigma(r), are temperature independent, \epsilon(r)\ exhibits a moderate decrease with generalized Drude analysis shows that the plasma frequency is independent of temperature, but decreases with decreasing doping. The scattering rate increases with temperature, and also increases with decreasing doping, consistent with stronger coupling in the underdoped regime. The mass-enhancement is small but increases to 30-40% at delta = 0.6. Difficulties in reconciling the results with some current theories of high-T-c materials are discussed. Finally, the surface plasmon propagation lengths and penetration depths are shown to vary systematically with doping. (C) 2003 Elsevier B.V. All rights reserved.

Prism coupler with variable coupling gap

The construction and operation of a prism/variable-gap/sample system (or variable-gap Otto coupler) for the excitation of surface electromagnetic modes is reported. This system has been used for the observation and characterization of surface plasmon polaritons on thin film structures. The initial alignment of prism and sample is performed under gravity and the subsequent gap variation is performed by means of a single actuator operating a flexure stage on which the prism is mounted. The flexure stage ensures the maintenance of good parallelism between sample and prism as the gap dimension is varied. The coupler has also served as a prototype, in terms of design principle, for the construction of a more sophisticated, variable-gap Otto coupler that can operate in vacuum at temperatures from ambient to 85 K.

Genomic insights into the origin of parasitism in the emerging plant pathogen Bursaphelenchus xylophilus.

Bursaphelenchus xylophilus is the nematode responsible for a devastating epidemic of pine wilt disease in Asia and Europe, and represents a recent, independent origin of plant parasitism in nematodes, ecologically and taxonomically distinct from other nematodes for which genomic data is available. As well as being an important pathogen, the B. xylophilus genome thus provides a unique opportunity to study the evolution and mechanism of plant parasitism. Here, we present a high-quality draft genome sequence from an inbred line of B. xylophilus, and use this to investigate the biological basis of its complex ecology which combines fungal feeding, plant parasitic and insect-associated stages. We focus particularly on putative parasitism genes as well as those linked to other key biological processes and demonstrate that B. xylophilus is well endowed with RNA interference effectors, peptidergic neurotransmitters (including the first description of ins genes in a parasite) stress response and developmental genes and has a contracted set of chemosensory receptors. B. xylophilus has the largest number of digestive proteases known for any nematode and displays expanded families of lysosome pathway genes, ABC transporters and cytochrome P450 pathway genes. This expansion in digestive and detoxification proteins may reflect the unusual diversity in foods it exploits and environments it encounters during its life cycle. In addition, B. xylophilus possesses a unique complement of plant cell wall modifying proteins acquired by horizontal gene transfer, underscoring the impact of this process on the evolution of plant parasitism by nematodes. Together with the lack of proteins homologous to effectors from other plant parasitic nematodes, this confirms the distinctive molecular basis of plant parasitism in the Bursaphelenchus lineage. The genome sequence of B. xylophilus adds to the diversity of genomic data for nematodes, and will be an important resource in understanding the biology of this unusual parasite.

INCIDENCE AND CLINICAL IMPORTANCE OF PERIOPERATIVE HISTAMINE-RELEASE - RANDOMIZED STUDY OF VOLUME LOADING AND ANTIHISTAMINES AFTER INDUCTION OF ANESTHESIA

Although histamine release is recognised as a common event during anaesthesia and surgery, few clinicians judge the resultant cardiorespiratory disturbances serious enough to warrant prophylaxis with antihistamines. We have assessed the incidence and importance of histamine release in a randomised 2 x 2 factorial study.

ANISOTROPY OF OPTICAL-CONSTANTS OF YBCO

Otto configuration attenuated total reflection (ATR) measurements of the excitation of surface plasmons in the infrared have been carried out on YBCO films deposited on MgO (100) substrates. The dielectric constants for YBCO at 3.392 mu m are determined to be -10 + 15i for c-axis material. The anisotropic nature of the cuprate is seen from films with other orientations: nearly a-axis material has constants of 4.0 + 7.0i. It is thus not metallic in its optical response along the c-axis which lies parallel to the substrate plane. Ellipsometric measurements in the visible on c-axis material point to a maximum surface plasmon energy of 1 eV.
