Nongonierma, Alice B; Lalmahomed, Mehdeeyah; Paolella, Sara; Fitzgerald, Richard J. (Elsevier, 2017)

A multifactorial [temperature (40, 50 and 60 °C), hydrolysis time (60, 150 and 240 min) and enzyme to substrate ratio (E:S; 1.0, 1.5 and 2.0%)] design of experiments (DOE) was used to optimise the release of dipeptidyl ...

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 ...

Milk protein-derived peptides induce 5-HT2C-mediated satiety,in vivo

Schellekens, Harriët; Nongonierma, Alice B; Clarke, Gerard; van Oeffelen, Wesley E.P.A; Fitzgerald, Richard J.; Dinan, Timothy G; Cryan, John F (Elsevier, 2014)

This study investigates the ability of milk protein-derived peptides to specifically activate the serotonin 2C (5-HT2C) receptor, a key receptor in central regulation of food intake. A dose dependent 5-HT2C receptor ...

Milk proteins as a source of tryptophan-containing bioactive peptides

Nongonierma, Alice B; Fitzgerald, Richard J. (Royal Society of Chemistry, 2015)

Tryptophan (W) is an essential amino acid which is primarily required for protein synthesis. It also acts as a precursor of key biomolecules for human health (serotonin, melatonin, tryptamine, niacin, nicotinamide adenine ...

Miscanthus biochar promotes growth of spring barley and shifts bacterial community structures including phosphorus and sulfur mobilizing bacteria

Fox, Aaron; Gahan, Jacinta; Ikoyi, I; Kwapinski, Witold; O'Sullvan, Orla; Cotter, Paul D; Schmalenberger, Achim (Elsevier, 2016)

Biochar has shown great potentials in plant growth promotion but its effect on soil bacteria that potentially support plant growth is less well understood. In this study, the effect of biochar soil amendment was investigated ...

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 ...

Noseband use in equestrian sports - an international study

Doherty, Orla; Casey, Vincent; McCreevy, Paul; Arkins, Sean (Public Library of Science, 2017)

Nosebands are used by riders to prevent the horse from opening its mouth, to increase control and, in some cases, to comply with the competition rules. While equestrian texts traditionally recommend that two adult human ...

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 objective measure of noseband tightness and Its measurement using a novel digital tightness gauge

Doherty, Orla; Conway, Thomas; Conway, Richard; Murray, Gerard; Casey, Vincent (Public Library of Science, 2017)

Noseband tightness is difficult to assess in horses participating in equestrian sports such as dressage, show jumping and three-day-eventing. There is growing concern that nosebands are commonly tightened to such an extent ...

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 ...

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

Brosnan, Stephanie (University of Limerick, 2011)
