The State of the Judiciary, 2009

Thank you for inviting me again this year to talk with you about the condition of Iowa’s judicial branch. As your partner in government, we look forward to working with you on issues affecting the administration of justice. If I could capture the condition of our courts, indeed the condition of our state, in a few words, it would be: “We live in challenging times.” No one knows the true meaning of this phrase better than those Iowans hit by natural disasters. But my focus today is, of course, on the courts. Ensuring the delivery of equal, affordable and accessible justice is always challenging work, but it will be especially so this year and the next in light of the State’s budget problems. Given the magnitude of this challenge, it is even more imperative that we work together in the spirit of unity, candor and cooperation. And I address you today in this spirit. We are deeply concerned, as you are, about the present financial situation and its effect on individual Iowans. Naturally, we are particularly troubled about its impact on the delivery of justice to our citizens. Even in good economic times, the administration of justice is difficult to fulfill given the sheer volume and complexity of problems Iowans bring to their courthouses. Because of the effects of the nation’s economic downturn, people will need access to justice now more than ever. We already see this happening. The number of mortgage foreclosure cases in Iowa rose 14% in the past year. Debt collection cases increased 20% in the same time. An increase in these types of cases is predictable in tough economic times, but other types of problems may escalate as well. Some experts fear that a recession may also give rise to more crime, child abuse, domestic violence, and substance abuse. Naturally, for the sake of the people who may be harmed by these problems, we hope they do not occur. If they do, however, these matters will demand our immediate attention.

Amoeba-resisting Chlamydiales present in domestic drinking water and their potential role in pneumonia

Chlamydia-related bacteria classified in the Chlamydiales order, are strictly intracellular bacteria and are able for the most to replicate in free-living amoebae. Amoebae, ubiquitous in the environment and especially in water, are very resistant to disinfection used in drinking water production. Thus, amoebae may reach easily the distribution and domestic water system, potentially sheltering amoeba-resisting bacteria including Legionella, mycobacteria and Chlamydiales. Indeed, some of these amoeba-resisting bacteria have been shown to cause respiratory infections in people inhaling contaminated water. Therefore, an environmental and clinical study was conducted to determine if Chlamydiales bacteria are also involved in respiratory infections and if a transmission through domestic drinking water could occur. First, large scale molecular and serological tools specific of Chlamydia-related bacteria were developed and then were applied on clinical samples from patients with and without pneumonia. Simultaneously, water and biofilm samples from households of the same patients were investigated using molecular and culture methods for the presence of Chlamydiales bacteria. Chlamydiales were detected in the nasopharyngeal flora from patients with and without pneumonia. However, no significant difference was observed between both groups. Conversely, serological investigations showed that antibody reactivity against members of the Criblamydiaceae was associated with pneumonia. The thesis provided very efficient tools that showed the presence of Chlamydiales in human nasopharyngeal flora as well as in the majority of the domestic drinking water. However, no transmission from domestic drinking water to human could be demonstrated. These tools will help in the future specifying the ecology and pathogenicity of the Chlamydia-re\ated bacteria and especially of the species belonging to the Criblamydiaceae family.

Retinal degeneration progression changes lentiviral vector cell targeting in the retina

Ce travail de thèse a été réalisé au sein de l'Unité de Thérapie Génique et Biologie des Cellules Souches de l'Hôpital Jules- Gonin dans le Service d'Ophtalmologie de l'Université de Lausanne. Ce laboratoire recherche des solutions thérapeutiques pour des maladies dégénératives et incurables de la rétine comme les rétinites pigmentaires (RP). Ayant déjà montré certains résultats dans le domaine, la thérapie génique a été notre outil pour ce travail. Cette méthode se base sur le principe de remplacer un gène déficient par sa copie normale, en transportant celle-ci au coeur même du noyau par un vecteur. Il existe à l'heure actuelle différents vecteurs. Un des plus efficaces est un vecteur viral non-réplicatif : le lentivirus, dérivé de HIV-1. Celui-ci a la capacité d'intégrer le génome de la cellule cible, lui conférant ainsi un nouveau matériel génétique. Notre but a été d'établir le tropisme du lentivirus dans une rétine en dégénérescence. Ce lentivirus est connu pour transduire efficacement les cellules de l'épithélium pigmentaire rétinien dans l'oeil adulte sain, ainsi que celles de la neurorétine, mais ce, uniquement durant le développement. On sait aussi que le vecteur lentiviral présente un tropisme différent selon les enveloppes dont il est muni ; par exemple, le lentivirus avec une enveloppe Mokola est connu pour transduire les cellules gliales du système nerveux central. La rétine qui dégénère montre quant à elle des changements de sa structure qui pourraient influencer la diffusion du vecteur et/ou son tropisme. Le postulat de base a été le suivant : chez l'adulte, la transduction des neurones de la rétine via le lentivirus pourrait être facilitée par l'altération de la membrane limitante externe induite par la dégénérescence (meilleure pénétrance du virus). D'un point de vue technique, nous avons utilisé deux types distincts de modèles murins de dégénérescence rétinienne : des souris Balb/C soumises à une dose toxique de lumière et les souris Rhodopsin knockout, animaux génétiquement modifiés. Comme vecteur viral, nous avons employé deux différents pseudotypes de lentivirus (caractérisés par les enveloppes virales) avec différents promoteurs (séquence d'ADN qui initie la transduction et confère la spécificité d'expression d'un gène). En changeant l'enveloppe et le promoteur, nous avons essayé de trouver la meilleure combinaison pour augmenter l'affinité du vecteur vis-à-vis des photorécepteurs d'abord, puis vis-à-vis d'autres cellules de la rétine. Nos résultats ont montré que la membrane limitante externe est effectivement altérée chez les deux modèles de dégénérescence, mais que cette modification ne favorise pas la transduction des photorécepteurs lorsqu'on utilise un vecteur lentiviral contenant une enveloppe VSVG et un promoteur photorécepteur-spécifique ou ubiquitaire. En effet, une forte réaction gliale a été observée. Par contre, en utilisant le lentivirus avec une enveloppe Mokola et un promoteur ubiquitaire, nous avons constaté une très bonne transduction au niveau des cellules de Millier dans la rétine en dégénérescence, phénomène non observé chez les souris sauvages. Ce travail a donc permis de trouver un vecteur viral efficace pour atteindre et transduire les cellules de Miiller, ceci seulement pendant la dégénérescence de la rétine. Ces cellules, une fois transduites, pourraient être utilisées pour sécréter dans la rétine des agents thérapeutiques tels que des facteurs neurotrophiques pour soutenir la survie des photorécepteurs ou des facteurs anti-angiogéniques pour prévenir la néo-vascularisation lors de diabète ou de dégénérescence maculaire liée à l'âge. - In normal mice, the lentiviral vector (LV) is very efficient to target the RPE cells, but transduces retinal neurons well only during development. In the present study, the tropism of LV has been investigated in the degenerating retina of mice, knowing that the retina structure changes during degeneration. We postulated that the viral transduction would be increased by the alteration of the iuter limiting membrane (OLM). Two different LV pseudotypes were tested using the VSVG arid the Mokola envelopes, as well as two animal models of retinal degeneration: light-damaged Balb-C and Rhodopsin knockout (Rho-/-) mice. After light damage, the OLM is altered and no significant increase of the number of transduced photoreceptors can be obtained with a LV-VSVG-Rhop-GFP vector. In the Rho-/- mice, an altération of the OLM was also observed, but the possibility of transducing photoreceptors was decreased, probably by ongoing gliosis. The use of a ubiquitous promoter allows better photoreceptor transduction, suggesting that photoreceptór-specific promoter activity change during late stages of photoreceptor degeneration. However, the number of targeted photoreceptors remains low. In contrast, LV pseudotyped with the tfokola envelope allows a wide dispersion of the ctor into the retina (corresponding to the injection bleb) with preferential targeting of Muller cells, a situation Mc\ does ot occur in the wild- type retina. Mokola-pseudotyped lentiviral vectors may serve to engineer these glial cells to deliver secreted therapeutic factors to a diseased area of the retina.

Els àmbits de pràctica professional en els estudis de psicologia: present i futur

Els alumnes de Psicologia, quan inicien els seus estudis universitaris, sovint tenen una imatge parcial i esbiaixada de l’ampli ventall de possibilitats professionals de què disposa el psicòleg en l’àmbit aplicat. Seria desitjable que aquestes representacions inicials anessin modificant-se al llarg dels estudis per anar-se apropant als perfils existents en la pràctica professional.Els plans d’estudi anteriors a la reforma del Espai Europeu d’Educació Superior difícilment assolien aquest objectiu en l’àmbit de la Psicologia: una llicenciatura estructurada en àrees de coneixement, no sempre directament vinculades a perfils professionals, i poques hores de pràctica en centres aplicats, hi contribuïen clarament. Però les múltiples reformes que planteja la convergència europea a nivell d’estudis superiors, introdueixen un seguit de modificacions importants al respecte que poden resultar avantatjoses: l’increment de les hores de pràctiques tutelades en centres aplicats, tant en els estudis de Grau i com de Màster, així com la clara correspondència entre, d’una banda, els perfils professionals de la Psicologia i, per una altra, els quatre Màsters que s’ofereixen a Espanya, en són alguns exemples. El present article analitza, no només el curs de la reforma de la titulació de Psicologia en l’estat espanyol en relació als àmbits de pràctica professional, si no que també recull els que es contemplen en el marc universitari de la convergència europea, partint de la directrius de l’interessant projecte EuroPsy (European Diploma of Psychology).Finalment, es reflexiona sobre les àrees de pràctica professional envers les àrees d’especialització en Psicologia, així com de les òptimes perspectives de creixement que presenta la professió en un futur immediat

CABO VERDE: DE UM “ESTADO INVIÁVEL” AO PRAGMATISMO NA POLÍTICA EXTERNA

O artigo procura compreender de forma sincrónica as linhas fundamentais da política externa de Cabo Verde e seus reflexos nas relações internacionais, abarcando o período, desde a independência à actualidade. A perspectiva central é a de que a independência em 1975 representou uma nova era para o Estado de Cabo Verde, embora se tenha propalado a ideia de um Estado inviável. A estratégia para ultrapassar esta situação passava por uma aposta activa nas relações internacionais, nomeadamente numa política externa pragmática que se ajustasse num quadro de concertação e interacção com outros Estados. Procuramos, através de uma abordagem interdisciplinar e interpretativa, analisar os fenómenos sociais-internacionais que se configuram na política externa cabo-verdiana, sabendo que estes se relacionam tanto no campo da história e da sociologia como no campo da ciência política e das relações internacionais. Propõe-se novos desafios para a política externa cabo-verdiana, numa conjuntura internacional abalada pela crise financeira, uma aposta para uma maior integração regional no continente africano, aproveitando de forma estratégica o continente como nova fronteira de desenvolvimento.

GUINEA-BISSAU: The Role of Local and International NGOs in Environmental Preservation and Sustainability of the Bijagos Archipelago

Bijagos Archipelago in Guinea-Bissau is at present subject to numerous external impacts that affect its centuries old balance. Since 1975 Guinean society has been using its natural resources in an uncontrolled way over the territory and especially in the coastal area. The archipelago has been increasingly raising interest, most of which is incompatible with the guarantee for a long-term sustainable development. It has also displayed a general impoverishment as far as resource preservation is concerned, due to internal demographic pressure of a population that has doubled since 1981 and to external pressure related to neighboring migrations and consequent depletion of non-renewable resources. This article aims to analyze the actions of local and international NGOs in the preservation and sustainability of the Bijagos Archipelago. We seek through an interdisciplinary approach to analyze the phenomena that are configured within the strategies of NGOs, on the assumption that these issues are articulated in the field of geography and sociology, as well as in politics and international cooperation. It is proposed new challenges to environmental issues, especially in a current situation shaken by constant instability internal and external policies.

Quantitative monitoring of tamoxifen in human plasma extended to 40 metabolites using liquid-chromatography high-resolution mass spectrometry: new investigation capabilities for clinical pharmacology.

Liquid-chromatography (LC) high-resolution (HR) mass spectrometry (MS) analysis can record HR full scans, a technique of detection that shows comparable selectivity and sensitivity to ion transitions (SRM) performed with triple-quadrupole (TQ)-MS but that allows de facto determination of "all" ions including drug metabolites. This could be of potential utility in in vivo drug metabolism and pharmacovigilance studies in order to have a more comprehensive insight in drug biotransformation profile differences in patients. This simultaneous quantitative and qualitative (Quan/Qual) approach has been tested with 20 patients chronically treated with tamoxifen (TAM). The absolute quantification of TAM and three metabolites in plasma was realized using HR- and TQ-MS and compared. The same LC-HR-MS analysis allowed the identification and relative quantification of 37 additional TAM metabolites. A number of new metabolites were detected in patients' plasma including metabolites identified as didemethyl-trihydroxy-TAM-glucoside and didemethyl-tetrahydroxy-TAM-glucoside conjugates corresponding to TAM with six and seven biotransformation steps, respectively. Multivariate analysis allowed relevant patterns of metabolites and ratios to be associated with TAM administration and CYP2D6 genotype. Two hydroxylated metabolites, α-OH-TAM and 4'-OH-TAM, were newly identified as putative CYP2D6 substrates. The relative quantification was precise (<20 %), and the semiquantitative estimation suggests that metabolite levels are non-negligible. Metabolites could play an important role in drug toxicity, but their impact on drug-related side effects has been partially neglected due to the tremendous effort needed with previous MS technologies. Using present HR-MS, this situation should evolve with the straightforward determination of drug metabolites, enlarging the possibilities in studying inter- and intra-patients drug metabolism variability and related effects.

Condiciones bio-oceanográficas en San José, islas Lobos de Afuera, Perú. 2010

En este estudio se muestra la variabilidad oceanográfica que se presenta en Lambayeque. Se evidenció con la generación del evento frío La Niña, después que se registrara el arribo de ondas Kelvin hacia la costa desde fines del 2009, lo que se llegó a considerar como la ocurrencia de un evento El Niño de intensidad moderada. Esta situación propició que los recursos pesqueros se ausentaran de sus áreas habituales de pesca, sumado a la presencia de oleajes anómalos y fuertes vientos que dificultaron las faenas de pesca. Durante el 2010, la Extensión Sur de la Corriente de Cromwell (ESCC) se presentó moderadamente fortalecida en marzo, evidenciada por la relativa alta concentración de oxígeno disuelto en las áreas más profundas de San José, situación inusual para la época en la zona. La proyección de la ESCC se vio intensificada en abril, pero comenzó a debilitarse en junio hasta ausentarse en noviembre, como se puede deducir de los valores de oxígeno encontrados cerca del fondo durante las prospecciones realizadas.

Old ferricrete landscape dismantling in Central Africa rain forest zone: formation of the present downslope iron accumulations.

Present downslope iron accumulations were investigated in the rainforest zone in southern Cameroon. Six clay and Fe-hydroxide dominated patterns have been identified and occur on the lower part of hill slopes. They can be subdivided in three different sequences, related to gentle, moderate or steep slopes. They are discontinuous with respect to the dismantling zone of the old ferricrete cap formed at Cretaceous period. They show a gradual development from a soft Fe-crust (carapace) to a vesicular facies that will, with time, cover the whole landscape again.
