Assessing the impact of long-term soil phosphorus on N-transformation pathways using 15N tracing (2020)

O'Neill, R.M.; Krol, D. J.; Wall, D.; Renou-Wilson, Florence; Müller, Cristoph; et al.

Abstract:

A laboratory incubation study was conducted on a temperate grassland soil to quantify the main mineral nitrogen (N) transformation rates and pathways via a15N tracing approach. Soil samples were taken from a long-term phosphorus (P) trial to investigate the effects on gross N-transformations under high and low phosphorus amendment. The soils were incubated over a 2-week period and treated with ammonium-nitrate (NH4NO3) which was applied to the soil both with and without a glucose amendment and labelled with 15N either on the ammonium (NH4+) or nitrate (NO3−) moiety at 50% atom enrichment. The results showed immobilisation to greatly outweigh mineralisation and that NO3− was predominantly produced via heterotrophic nitrification. Individual pathways for NO3− production were quantified including oxidation of NH4+, recalcitrant and labile organic N. Oxidation of labile organic N to NO3−, a newly considered pathway, accounted for between 63 and 83% of total NO3− production across the va...

Evaluating the optimum rest period prior to blood collection for fractionated plasma free metanephrines analysis (2016)

Evaluating the optimum rest period prior to blood collection for fractionated plasma free metanephrines analysis (2016)

Griffin, T.P.; Casey, R.; Wall, D.; Bell M.; O'Shea, P.M.

Abstract:

The high diagnostic accuracy of plasma metanephrines (PMets) in the di-agnosis of Phaeochromocytoma/Paraganglioma (PPGL) is well established. Considerable controversy exists regarding optimum sampling conditions for PMets. The use of reference intervals that do not compromise diagnostic sensitivity is recommended. However, the optimum rest period prior to sampling has yet to be clearly established. The aim of this study was to evaluate PMets concentrations in paired blood samples collected following 30 and 40 min seated-rest prior to sampling, in patients in whom it was clinically rea-sonable to suspect that PPGL may be present.

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- Final Summary Report. (2013)

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- Final Summary Report. (2013)

Berrow, S.D.; O’Brien, J.; O’Connor, I.; McGrath, D.; Wall, D.

Abstract:

Irish waters are internationally important for cetaceans (whales, dolphins and porpoises), with 24 species recorded to date. These range from the harbour porpoise, the smallest species in European waters, to the blue whale, the largest animal to ever have lived on Earth. All cetaceans and their habitats are protected under Irish and international law. The research termed Marine Mammals and Megafauna in Irish Waters – behaviour, distribution and habitat use was delivered under six Work Packages. The deliverables under this project will provide data which could be used to address a wide range of issues, and will contribute to developing policy advice on meeting Ireland’s statutory obligations.

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- WP 2: Developing Acoustic Monitoring Techniques (2013)

O’Brien, J.; Beck, S.; Wall, D.; Pierini, A.

Abstract:

All cetaceans and their habitats are protected under Irish and international law. The research termed Marine Mammals and Megafauna in Irish Waters – behaviour, distribution and habitat use was delivered under six Work Packages. Cetacean line transect surveys were conducted under Work Package 1 with the following goals: 1. Providing a baseline cetacean distribution and relative abundance data set for the Irish EEZ; 2. Filling spatial and temporal gaps identified in cetacean survey effort within the EEZ; 3. Preparing an Atlas of cetacean distribution and relative abundance for Irish waters; 4. Assessing the temporal use of marine habitats by cetaceans in Irish waters.

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- WP4 Research into Ecosystem Links and Habitat Use between Cetaceans and Fisheries in the Celtic Sea (2013)

Healy, H.; Minto, C.; Wall, D.; O'Donnell, D.; O’Connor, I.

Abstract:

Visual line transect survey data for cetaceans were simultaneously collected during synoptic acoustic sampling surveys of small schooling pelagic fish, i.e. herring (Clupea harengus) and sprat (Sprattus sprattus) in the Celtic Sea, off the south coast of Ireland, from 2004 to 2009. These data were used to investigate the interactions of cetaceans with biological and environmental variables in the survey area. Geographic information systems and generalized linear and generalized additive models were used in this study.

Young adult type 1 diabetes care in the west of ireland: an audit of hospital practice (2018)

Casey, R.; O'Hara, M. C.; Cunningham, A.; Wall, D.; Geoghegan, R.; Hynes, L.; McGuire, B.; Gately, M.; Bell, M.; Dinneen, S. F.

Abstract:

Background: It is well recognised that management of young adults with type 1 diabetes (T1DM) poses difficult challenges for physicians and health care organisations as a whole. In Ireland and in particular the west of Ireland there has been little audit or research on young adults with T1DM and the services available to them. Design: In 2011 a retrospective review of this patient population in our territory referral centre was carried out. Results: The average glycaemic control in this population was poor at 81 mmols/mol and diabetes related complications were present in 32%. Engagement by this population with services was poor with an average of 3 missed clinic appointments over a 24 month period. Conclusion: These results have prompted a re think of how health care professionals can deliver a service that better suits the needs of this challenging patient group.
