Analysis of functional and anatomical success following endonasal dacryocystorhinostomy

RésuméLes sténoses des voies lacrymales sont fréquentes surtout chez les patients âgés et provoquent en général un epiphora avec parfois des dacryocystites aiguës ou chroniques. La dacryocystorhinostomie par voie externe (DCREX) a été la technique de choix pour traiter les sténoses post-canaliculaires au XXe siècle. Avec l'avènement de l'endoscopie nasale, l'abord endonasal est devenu facilement accessible et depuis une dizaine d'années, la dacryocystorhinostomie par voie endonasale (DCREN) est en train de supplanter la DCREX dans la majorité des cas.Le but de ce travail est de déterminer les étiologies des sténoses des voies lacrimales, d'évaluer le taux de succès et les complications de la DCREN et de détailler les gestes associés peropératoires.Cette étude rétrospective porte sur 98 patients ayant subi 104 DCREN entre janvier 1994 et février 2006. 78 patients (53 femmes et 25 hommes) présentant 84 sténoses post- canaliculaires remplissent les critères d'inclusion de l'étude. L'âge moyen est de 59 ans (4 - 89 ans).Les résultats obtenus montrent un taux de succès fonctionnel de 94.9% après une première intervention (59/84 DCREN) et de 63.6% pour les DCREN secondaires qui nous ont été référées après d'autres interventions des voies lacrymales (25/84 DCREN). Le suivi postopératoire est de 36,8 mois (12-77 mois). On dénombre 61 gestes rhino-sinusaux associés à la DCREN. Les complications per- et postopératoires sont rares, essentiellement liées aux drains bicanaliculaires. Une étiologie n'a été retrouvée que dans 28% des cas.En conclusion, la DCREN donne d'excellents résultats et peu de complications. En raison des nombreux avantages par rapport à la voie externe et la possibilité du traitement simultané de la pathologie ORL parfois associée, la DCREN est devenue le traitement de premier choix pour les sténoses postcanaliculaires. Le principal défi, quelque soit le type de DCR, est de poser la bonne indication opératoire et en cas d'échec opératoire savoir méticuleusement analyser ses causes

The Role and Future Development of Supportive Housing for Older People in Ireland

The Role and Future Development of Supportive Housing for Older People in Ireland The standard and suitability of older peopleâ?Ts accommodation is vital to their health and quality of life and a key factor in their capacity to take care of themselves or to be cared for should they become dependent. The NCAOP, therefore, welcomes an increased national policy focus on older peopleâ?Ts housing circumstances, as demonstrated in the current partnership agreement, Towards 2016: Ten-Year Framework Social Partnership Agreement 2006-2015 (Government of Ireland, 2006), and the National Action Plan for Social Inclusion 2007-2016 (Government of Ireland, 2007).

Functional and structural basis for a bacteriophage homolog of human RAD52.

In eukaryotes, homologous recombination proteins such as RAD51 and RAD52 play crucial roles in DNA repair and genome stability. Human RAD52 is a member of a large single-strand annealing protein (SSAP) family [1] and stimulates Rad51-dependent recombination [2, 3]. In prokaryotes and phages, it has been difficult to establish the presence of RAD52 homologs with conserved sequences. Putative SSAPs were recently found in several phages that infect strains of Lactococcus lactis[4]. One of these SSAPs was identified as Sak and was found in the virulent L. lactis phage ul36, which belongs to the Siphoviridae family [4, 5]. In this study, we show that Sak is homologous to the N terminus of human RAD52. Purified Sak binds single-stranded DNA (ssDNA) preferentially over double-stranded DNA (dsDNA) and promotes the renaturation of long complementary ssDNAs. Sak also binds RecA and stimulates homologous recombination reactions. Mutations shown to modulate RAD52 DNA binding [6] affect Sak similarly. Remarkably, electron-microscopic reconstruction of Sak reveals an undecameric (11) subunit ring, similar to the crystal structure of the N-terminal fragment of human RAD52 [7, 8]. For the first time, we propose a viral homolog of RAD52 at the amino acid, phylogenic, functional, and structural levels.

Southernmost finding of Lymnaea viatrix orbigny, 1835 (Pulmonata: Lymnaeidae), intermediate host of Fasciola hepatica (Linnaeus, 1758) (Trematoda: Digenea), in urban and rural areas of Patagonia, Argentina

We report the first finding of Lymnaea viatrix south of parallel 41ºS, in rural and urban areas from Argentina. Ninety snails were collected during year 2000, from a concrete pond at a Public Square in El Bolsón Village, Río Negro province, and 811 snails in November 1999, and during 2000 from waterbodies within a farm at Cholila locality, Chubut province. Fasciola hepatica infection was detected in 0.9% snails from the rural area. We discuss the potential risk of L. viatrix to public health in urban areas and its epidemiological importance in rural areas of the Andean Patagonian region.

The Role and Future Development of the Meals-on-Wheels Service for Older People in Ireland

This report provides, for the first time, a snapshot of the meals-on-wheels service in Ireland and gives a unique insight into client and provider perceptions of the service. The research findings underline the dual importance of the service for clients, who noted that it is a vital source of both nutritious meals and social contact and connectivity to the wider community. From a supply side perspective, the research findings point to the wide organisational diversity that exists within the service and the critical role that volunteers play, as well as highlighting difficulties that many services currently experience.

Evaluation des modifications anatomiques et fonctionnelles de la macula après chirurgie des membranes néovasculaires rétrofovéolaires dans la dégénérescence maculaire liée à l'âge [Evaluation of functional and anatomical changes in the macula after surgery for retro-foveal neovascularization of membranes in age-related macular degeneration].

PURPOSE: The aim of this study was to evaluate the direct effect of surgical treatment of subfoveolar neovascular membranes in age related macular degeneration to macular functions. PATIENTS AND METHODS: Thirteen eyes of 13 patients were included in this study. Macular function was assayed by visual acuity and central visual field using the Octopus perimeter before surgery and in the first three post operative months. Pre and post operative fluorescein angiography frames were digitalized and the size of each lesions were compared. RESULTS: After a 3 months follow up, visual acuity remained stable or improved in 66% of the patients. However, visual acuity was better than 0.1 in 15% of the patients. Central visual field comparison disclosed a significant worsening of the retinal sensitivity in the 3 degree field surrounding the central point. On fluorescein frames, submacular scar was 141% of the size of the neovascular membrane. After a mean follow up of 6.9 months (range 3-14), one case of recurrence occurred. A cataract was observed in 85% of the phakic patients followed for more than six months. CONCLUSION: After a short term follow up, surgery can stabilise visual acuity, even though it remains poor. A worsening of the scotoma in the 3 degrees surrounding the central point is observed. However, patients noticed a subjective visual improvement in 62% of the case.

Phenotypic, functional, and quantitative characterization of canine peripheral blood monocyte-derived macrophages

The yield as well as phenotypic and functional parameters of canine peripheral blood monocyte-derived macrophages were analyzed. The cells that remained adherent to Teflon after 10 days of culture had high phagocytic activity when inoculated with Leishmania chagasi. Flow cytometric analysis demonstrated that more than 80% of cultured cells were positive for the monocyte/macrophage marker CD14.

A discrete forest in a continuous landscape : investigating interactions between natural resource management and sustainable development

Summary Forests are key ecosystems of the earth and associated with a large range of functions. Many of these functions are beneficial to humans and are referred to as ecosystem services. Sustainable development requires that all relevant ecosystem services are quantified, managed and monitored equally. Natural resource management therefore targets the services associated with ecosystems. The main hypothesis of this thesis is that the spatial and temporal domains of relevant services do not correspond to a discrete forest ecosystem. As a consequence, the services are not quantified, managed and monitored in an equal and sustainable manner. The thesis aims were therefore to test this hypothesis, establish an improved conceptual approach and provide spatial applications for the relevant land cover and structure variables. The study was carried out in western Switzerland and based primarily on data from a countrywide landscape inventory. This inventory is part of the third Swiss national forest inventory and assesses continuous landscape variables based on a regular sampling of true colour aerial imagery. In addition, land cover variables were derived from Landsat 5 TM passive sensor data and land structure variables from active sensor data from a small footprint laserscanning system. The results confirmed the main hypothesis, as relevant services did not scale well with the forest ecosystem. Instead, a new conceptual approach for sustainable management of natural resources was described. This concept quantifies the services as a continuous function of the landscape, rather than a discrete function of the forest ecosystem. The explanatory landscape variables are therefore called continuous fields and the forest becomes a dependent and function-driven management unit. Continuous field mapping methods were established for land cover and structure variables. In conclusion, the discrete forest ecosystem is an adequate planning and management unit. However, monitoring the state of and trends in sustainability of services requires them to be quantified as a continuous function of the landscape. Sustainable natural resource management iteratively combines the ecosystem and gradient approaches. Résumé Les forêts sont des écosystèmes-clés de la terre et on leur attribue un grand nombre de fonctions. Beaucoup de ces fonctions sont bénéfiques pour l'homme et sont nommées services écosystémiques. Le développement durable exige que ces services écosystémiques soient tous quantifiés, gérés et surveillés de façon égale. La gestion des ressources naturelles a donc pour cible les services attribués aux écosystèmes. L'hypothèse principale de cette thèse est que les domaines spatiaux et temporels des services attribués à la forêt ne correspondent pas à un écosystème discret. Par conséquent, les services ne sont pas quantifiés, aménagés et surveillés d'une manière équivalente et durable. Les buts de la thèse étaient de tester cette hypothèse, d'établir une nouvelle approche conceptuelle de la gestion des ressources naturelles et de préparer des applications spatiales pour les variables paysagères et structurelles appropriées. L'étude a été menée en Suisse occidentale principalement sur la base d'un inventaire de paysage à l'échelon national. Cet inventaire fait partie du troisième inventaire forestier national suisse et mesure de façon continue des variables paysagères sur la base d'un échantillonnage régulier sur des photos aériennes couleur. En outre, des variables de couverture ? terrestre ont été dérivées des données d'un senseur passif Landsat 5 TM, ainsi que des variables structurelles, dérivées du laserscanning, un senseur actif. Les résultats confirment l'hypothèse principale, car l'échelle des services ne correspond pas à celle de l'écosystème forestier. Au lieu de cela, une nouvelle approche a été élaborée pour la gestion durable des ressources naturelles. Ce concept représente les services comme une fonction continue du paysage, plutôt qu'une fonction discrète de l'écosystème forestier. En conséquence, les variables explicatives de paysage sont dénommées continuous fields et la forêt devient une entité dépendante, définie par la fonction principale du paysage. Des méthodes correspondantes pour la couverture terrestre et la structure ont été élaborées. En conclusion, l'écosystème forestier discret est une unité adéquate pour la planification et la gestion. En revanche, la surveillance de la durabilité de l'état et de son évolution exige que les services soient quantifiés comme fonction continue du paysage. La gestion durable des ressources naturelles joint donc l'approche écosystémique avec celle du gradient de manière itérative.

Functional and transcriptional induction of aquaporin-1 gene by hypoxia; analysis of promoter and role of Hif-1α.

Aquaporin-1 (AQP1) is a water channel that is highly expressed in tissues with rapid O(2) transport. It has been reported that this protein contributes to gas permeation (CO(2), NO and O(2)) through the plasma membrane. We show that hypoxia increases Aqp1 mRNA and protein levels in tissues, namely mouse brain and lung, and in cultured cells, the 9L glioma cell line. Stopped-flow light-scattering experiments confirmed an increase in the water permeability of 9L cells exposed to hypoxia, supporting the view that hypoxic Aqp1 up-regulation has a functional role. To investigate the molecular mechanisms underlying this regulatory process, transcriptional regulation was studied by transient transfections of mouse endothelial cells with a 1297 bp 5' proximal Aqp1 promoter-luciferase construct. Incubation in hypoxia produced a dose- and time-dependent induction of luciferase activity that was also obtained after treatments with hypoxia mimetics (DMOG and CoCl(2)) and by overexpressing stabilized mutated forms of HIF-1α. Single mutations or full deletions of the three putative HIF binding domains present in the Aqp1 promoter partially reduced its responsiveness to hypoxia, and transfection with Hif-1α siRNA decreased the in vitro hypoxia induction of Aqp1 mRNA and protein levels. Our results indicate that HIF-1α participates in the hypoxic induction of AQP1. However, we also demonstrate that the activation of Aqp1 promoter by hypoxia is complex and multifactorial and suggest that besides HIF-1α other transcription factors might contribute to this regulatory process. These data provide a conceptual framework to support future research on the involvement of AQP1 in a range of pathophysiological conditions, including edema, tumor growth, and respiratory diseases.
