Sixty to seventy-four? It's time you took the test for bowel cancer

This poster highlights the bowel cancer screening programme is being introduced for all 60 to 74 year olds. If you are in this age group a kit will be sent by post so you can do the test at home. You are encouraged to look out for the kit as it could save your life.

Bowel cancer screening: how to take your test (for people who are partially sighted)

This leaflet provides step-by-step instructions on using the Faecal Immunochemical�Test (FIT) for bowel cancer screening. This kit is slightly different to the one we usually use as part of Northern Ireland��'s bowel cancer screening programme. It is easier to complete for people who are partially sighted and is sent following discussion with the screening helpline team.

Cervical cancer: it's best to take the test (English and 11 translations)

Testing for high-risk human papillomavirus (HR-HPV) as triage and test of cure was introduced into the Northern Ireland Cervical Screening Programme on Monday 28 January 2013. This policy change will significantly alter the screening pathway for women with a mild dyskaryosis or borderline smear result.

Resistance to experimental autoimmune encephalomyelitis development in Lewis rats from a conventional animal facility

Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the brain and spinal cord that is mediated by CD4+ T lymphocytes specific to myelin components. In this study we compared development of EAE in Lewis rats from two colonies, one kept in pathogen-free conditions (CEMIB colony) and the other (Botucatu colony) kept in a conventional animal facility. Female Lewis rats were immunized with 100 µl of an emulsion containing 50 µg of myelin, associated with incomplete Freund's adjuvant plus Mycobacterium butyricum. Animals were daily evaluated for clinical score and weight. CEMIB colony presented high EAE incidence with clinical scores that varied from three to four along with significant weight losses. A variable disease incidence was observed in the Botucatu colony with clinical scores not higher than one and no weight loss. Immunological and histopathological characteristics were also compared after 20 days of immunization. Significant amounts of IFN-gamma, TNF-alpha and IL-10 were induced by myelin in cultures from CEMIB animals but not from the Botucatu colony. Significantly higher levels of anti-myelin IgG1 were detected in the CEMIB colony. Clear histopathological differences were also found. Cervical spinal cord sections from CEMIB animals showed typical perivascular inflammatory foci whereas samples from the Botucatu colony showed a scanty inflammatory infiltration. Helminths were found in animals from Botucatu colony but not, as expected, in the CEMIB pathogen-free animals. As the animals maintained in a conventional animal facility developed a very discrete clinical, and histopathological EAE in comparison to the rats kept in pathogen-free conditions, we believe that environmental factors such as intestinal parasites could underlie this resistance to EAE development, supporting the applicability of the hygiene hypothesis to EAE.

Mice Transgenic For Human Dominant Mutations Of The GUCY2D Gene

Purpose: Animal models are essential to study pathological mechanisms and to test new therapeutic strategies. Many mouse models mimic human rod loss but only a limited number simulate cone dystrophies. The importance of cone function for human vision highlights the need to engineer a model for cone degeneration. An approach of lentiviral-directed transgenesis was tested in mice to express a dominant mutant gene described in a human cone dystrophy.Methods: Lentiviral vectors (LV) encoding either hrGFPII or the human double mutant GUCY2DE837D/R838S cDNA under the control of a region of the pig arrestin-3 promoter (Arr3) were produced and used for lentiviral-derived transgenesis. PCR-genotyping determined the transgenic mouse ratio. The expression of GFP was then analyzed both in vivo and by immunohistochemistry in Arr3-GFPII mice. Functional analysis was performed by ERG at 5, 9, 16 and 24 weeks for Arr3-GUCY2DE837D/R838S mice. Mice were sacrificed at 10 months of age for both histological analysis and RNA extraction.Results: While all the newborns from the transgenesis using the LV-Arr3-GFPII were transgenic, one third of the newborns from the LV-Arr3-GUCY2DE837D/R838S transgenesis were positive. Expression of GFPII was demonstrated by in vivo imaging, while expression of the mutant GUCY2D transcript was detetected using RT-PCR. No severe alteration of the functional response was observed up to 24 weeks of age in the transgenic mice. No obvious modification of the retinal morphology was identified either.Conclusions: Lentiviral-directed transgenesis is a rapid and straightforward method to engineer transgenic mice. Protein expression can be specifically targeted to the retina and thus could help to study the effect of expression of dominant mutant proteins. In our case, Arr3-GUCY2DE837D/R838S mice have a less severe phenotype than that described for human patients. Further analyses are required to understand this difference but several modifications of the expression cassette might also help to increase the expression of the mutant protein and reinforce the phenotype. Interestingly, the same construct is less effective in mouse versus pig retina (see Arsenijevic et al. ARVO 2011 abstract).

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.

M-Library in an m-University : changing Models in the Open University of Catalonia

The general perspective of M-technologies and M-Services at the Spanish universities is not still in a very high level when we are ending the first decade of the 21st century. Some Universities and some of their libraries are starting to try out with M-technologies, but are still far from a model of massive exploitation, less than in some other countries. A deep study is needed to know the main reasons, study that we will not do in this paper. This general perspective does not mean that there are no significant initiatives which start to trust in M-technologies from Universities and their libraries. Models based in M-technologies make more sense than ever in open universities and in open libraries. That's the reason why the UOC's Library began in late 90s its first experiences in the M-Technologies and M-Libraries developments. In 1999 the appropriate technology offered the opportunity to carry out the first pilot test with SMS, and then applying the WAP technology. At those moments we managed to link-up mobile phones to the OPAC through a WAP system that allowed searching the catalogue by categories and finding the final location of a document, offering also the address of the library in which the user could loan it. Since then, UOC (and its library) directs its efforts towards adapting the offer of services to all sorts of M-devices used by end users. Left the WAP technology, nowadays the library is experimenting with some new devices like e-books, and some new services to get more feedback through the OPAC and metalibrary search products. We propose the case of Open University of Catalonia, in two levels: M-services applied in the library and M-technologies applied in some other university services and resources.

Evaluation of an enzyme-linked immunoelectrotransfer blot test for the confirmatory serodiagnosis of human toxocariasis

To improve the serodiagnosis of human toxocariasis, a sensitive and specific enzyme-linked immunoelectrotransfer blot (EITB-IgG) test was developed and evaluated using Toxocara canislarvae excretory-secretory antigens for detecting anti-Toxocara IgG antibodies. The EITB-IgG profile of toxocariasis was characterized by comparing 27 sera from patients with toxocariasis, 110 sera from healthy subjects and 186 sera from patients with other helminth diseases (ascariasis, ancylostomiasis, trichuriasis, enterobiasis, strongyloidiasis, hymenolepiasis, diphyllobothriasis, taeniasis, cysticercosis, hydatidosis and fascioliasis). Antigenic bands of 24, 28, 30, 35, 56, 117, 136 and 152 kDa were predominantly recognized in sera from all patients with toxocariasis. However, only bands of 24-35 kDa were highly specific for Toxocara infection (98.3%), whereas other antigenic bands observed displayed cross-reactivity. Additionally, when the results of the EITB-IgG test were compared to those of the ELISA-IgG test, a 100% concordance was observed for positive results in human toxocariasis cases. The concordance for negative results between the two tests for healthy subjects and patients with other helminth diseases were 96.3% and 53.7%, respectively, showing that the EITB-IgG test has a higher specificity than ELISA. In conclusion, the EITB-IgG test is a very useful tool to confirm the serological diagnosis of human toxocariasis.
