Dairy fats and cardiovascular disease: do we really need to be concerned?

Lordan, Ronan; Tsoupras, Alexandros; Mitra, Bhaskar; Zabetakis, Ioannis (MDPI, 2018)

Cardiovascular diseases (CVD) remain a major cause of death and morbidity globally and diet plays a crucial role in the disease prevention and pathology. The negative perception of dairy fats stems from the effort to ...
Detection and confirmation of mycobacterium avium subspecies paratuberculosis using ELISA and PCR methodologies

Dipeptidyl peptidase IV inhibitory and antioxidative properties of milk protein-derived dipeptides and hydrolysates

Nongonierma, Alice B.; Fitzgerald, Richard J. (Elsevier, 2013)

Selected synthetic dipeptides and milk protein hydrolysates were evaluated for their dipeptidyl peptidase IV (DPP-IV) inhibitory properties, and their superoxide (SO) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical ...
Dipeptidyl peptidase IV inhibitory properties of a whey protein hydrolysate: Influence of fractionation, stability to simulated gastrointestinal digestion and food-drug interaction

Nongonierma, Alice B.; Fitzgerald, Richard J. (Elsevier, 2013)

The in vitro dipeptidyl peptidase IV (DPP-IV) inhibitory activity of a whey protein hydrolysate (WPH) generated with a food-grade pancreatic enzyme preparation was studied. The 50 % inhibitory concentration (IC50) value ...
The dissemination of C10 cysteine protease genes in Bacteroides fragilis by mobile genetic elements

Thornton, Roibeard F.; Kagawa, Todd F.; O'Toole, Paul W.; Cooney, Jakki C. (BioMed Central, 2010)

Background: The C10 family of cysteine proteases includes enzymes that contribute to the virulence of bacterial pathogens, such as SpeB in Streptococcus pyogenes. The presence of homologues of cysteine protease genes in ...
The diversity of fungi in four Irish forest types

O'Hanlon, Richard (University of Limerick, 2011)

Sampling of the macrofungal sporocarps, ectomycorrhizal morphotypes and vascular plants was carried out in 28 plots from four forest types (ash, oak, Scot’s pine, Sitka spruce) between the years 2007 and 2009. A total ...
A dual targeted β-defensin and exome sequencing approach to identify, validate and functionally characterise genes associated with bull fertility

Whiston, Ronan; Finlay, Emma K.; McCabe, Matthew S.; Cormican, Paul; Flynn, Paul; Cromie, Andrew; Hansen, Peter J.; Lyons, Alan; Fair, Seán; Lonergan, Patrick; O'Farrelly, Cliona; Meade, Kieran G. (Nature Publishing Group, 2017)

Bovine fertility remains a critical issue underpinning the sustainability of the agricultural sector. Phenotypic records collected on >7,000 bulls used in artificial insemination (AI) were used to identify 160 reliable and ...
Effect of breed, plane of nutrition and age on growth, scrotal development, metabolite concentrations and on systemic gonadotropin and testosterone concentrations following a GnRH challenge in young dairy bulls

Byrne, C.J.; Fair, Seán; English, A.M.; Urh, C.; Sauerwein, H.; Crowe, M.A.; Lonergan, Patrick; Kenny, D.A. (Elsevier, 2017)

The onset of puberty in the bull is regulated by the timing of early GnRH pulsatility release from the hypothalamus, which has been demonstrated to be affected by plane of nutrition during calf-hood. The aim of this study ...
The effect of buttermilk or buttermilk powder addition on functionality, textural, sensory and volatile characteristics of Cheddar-style cheese
