The microbial mobilisation of sulphur and phosphorus in biochar amended soils

Fox, Aaron (University of Limerick, 2013)

Biochar amended soils have demonstrated various agronomic benefits, principally a plant growth promotion effect. The char’s impact, however, on macronutrient bio-availability and the microorganisms involved in their ...

Milk protein-derived peptide inhibitors of angiotensin-I-converting enzyme

Fitzgerald, Richard J.; Meisel, Hans (Cambridge University Press, 2000)

Numerous casein and whey protein-derived angiotensin-I-converting enzyme (ACE) inhibitory peptides/hydrolysates have been identified. Clinical trials in hypertensive animals and humans show that these peptides/hydrolysates ...

Modification of mesoporous silicates for immobilization of enzymes

Gaffney, Darragh; Cooney, Jakki C; Magner, Edmond (Springer, 2012)

Mesoporous silicates (MPS) possess ordered pore structures with pore diameters sufficiently large to accommodate a range of enzymes. The successful immobilization of an enzyme on MPS usually requires modification of the ...

Molecular typing of Irish Streptococcus equi ssp equi strains

Moloney, Emma (University of Limerick, 2011)

Streptococcus equi subsp. equi is the causative agent of strangles, a highly contagious upper respiratory infection of horses. A molecular typing scheme and database based on the variability of the S. equi SeM protein has ...

Nutrient pools in Sitka spruce and lodgepole pine forest biomass

Mangrinan, Eva Ros (University of Limerick, 2015)

Biomass harvesting may affect the nutrient pools of forests and impact negatively on forest ecosystems in the long-term. Appropriate knowledge regarding nutrient pools and potential nutrient removal is required for a ...

An open source tool for automated input data in simulation

Barlas, Panagiotis; Heavey, Cathal; Dagkakis, Georgios (D A A A M International Vienna, 2015)

Discrete Event Simulation (DES) is one of the most effective tools for planning, designing and improving material flows in production. One of the main weaknesses of operating DES is the exertion needed and costs spent on ...

Opioid peptides encrypted in intact milk protein sequences

Meisel, Hans; Fitzgerald, Richard J. (Cambridge University Press, 2000)

Opioid agonistic and antagonistic peptides which are inactive within the sequence of the precursor milk proteins can be released and thus activated by enzymatic proteolysis, for example during gastrointestinal digestion ...

Optimising parameters for the differentiation of SH-SY5Y cells to study cell adhesion and cell migration

Dwane, Susan; Durack, Edel; Kiely, Patrick A (BioMed Central, 2013)

Background: Cell migration is a fundamental biological process and has an important role in the developing brain by regulating a highly specific pattern of connections between nerve cells. Cell migration is required for ...

Oxalate secretion by ectomycorrhizal Paxillus involutus is mineral-specific and controls calcium weathering from minerals

Schmalenberger, Achim; Duran, A.L; Bray, A.W; Bridge, J; Bonneville, S; Benning, L.G; Romero-Gonzalez, M.E; Leake, J.R; Banwart, S.A (Nature Publishing Group, 2015)

Trees and their associated rhizosphere organisms play a major role in mineral weathering drivingcalcium fluxes from the continents to the oceans that ultimately control long-term atmosphericCO2 and climate through the ...

Partitioning of soil respiration in a beech forest using a trenching experiment.

Brosnan, Stephanie (University of Limerick, 2011)

Total soil respiration (RTOT) has two components; heterotrophic (RH) and autotrophic (RA) respiration. We aim to partition the components of RTOT in a beech (Fagus sylvatica L.) forest using a trenching experiment. The ...

Performance and progression of Irish point-to-point horses

Quish, Carol (University of Limerick, 2011)

Point-to-point races are steeplechase races for novice horses, some of which may subsequently graduate to professional National Hunt (NH) races on the racecourse. There have been significant changes in the Irish racing ...

Physicochemical and sensory characteristics of whey protein hydrolysates generated at different total solids levels

Spellman, David; O'Cuinn, Gerard; Fitzgerald, Richard J. (Cambridge University Press, 2005)

Whey protein hydrolysates were generated at different total solids (TS) levels (50–300 g/l) using the commercially available proteolytic preparation DebitraseTM HYW20, while enzyme to substrate ratio, pH and temperature ...

Predator versus prey: locust looming-detector neuron and behavioural responses to stimuli representing attacking bird predators

Santer, Roger D; Rind, Claire F; Simmons, Peter J (Public Library of Science, 2012)

Many arthropods possess escape-triggering neural mechanisms that help them evade predators. These mechanisms are important neuroethological models, but they are rarely investigated using predator-like stimuli because there ...

Pregnancy-specific glycoproteins bind integrin alpha IIb beta 3 and inhibit the platelet-fibrinogen interaction

Shanley, Daniel K; Kiely, Patrick A; Golla, Kalyan; Allen, Seamus; Martin, Kenneth; O'Riordan, Ronan T; Ball, Melanie; Aplin, John D; Singer, Bernard B; Caplice, Noel; Moran, Niamh; Moore, Tom (Public Library of Science, 2013)

Pregnancy-specific glycoproteins (PSGs) are immunoglobulin superfamily members encoded by multigene families in rodents and primates. In human pregnancy, PSGs are secreted by the syncytiotrophoblast, a fetal tissue, and ...

Profiling of the molecular weight and structural isomer abundance of macroalgae-derived phlorotannins

Heffernan, Natalie; Brunton, Nigel P; Fitzgerald, Richard J.; Smyth, Thomas J (MDPI, 2015)

Phlorotannins are a group of complex polymers of phloroglucinol (1,3,5-trihydroxybenzene) unique to macroalgae. These phenolic compounds are integral structural components of the cell wall in brown algae, but also play ...
