Serum concentrations of carboxyl-terminal propeptide of type I procollagen, amino-terminal propeptide of type III procollagen, cross-linked carboxl-terminal telopeptide of type I collagen, and their interrelationships in schoolchildren
(American Association for Clinical Chemistry, 1997)We report pediatric age- and sex-specific 95% reference intervals for procollagen type I C-terminal propeptide (PICP), the cross-linked C-terminal telopeptide of type I collagen (ICTP), and procollagen type III N-terminal ... -
Serum crosslaps: pediatric reference intervals from birth to 19 years of age
(American Association for Clinical Chemistry, 2002)During childhood growth, bone undergoes extensive modeling involving separate osteoblastic and osteoclastic processes. Markers of bone formation and resorption circulate at higher concentrations in children than in adults, ... -
Short-term foetal immobility temporally and progressively affects chick spinal curvature and anatomy and rib development
(2019)Congenital spine deformities may be influenced by movements in utero, but the effects of foetal immobility on spine and rib development remain unclear. The purpose of the present study was to determine (1) critical time-periods ... -
The significance of cerebral toxocariasis: a model system for exploring the link between brain involvement, behaviour and the immune response
(2013)Toxocara canis is a parasitic nematode that infects canines worldwide, and as a consequence of the widespread environmental dissemination of its ova in host faeces, other abnormal hosts including mice and humans are exposed ... -
Single cell analysis of tail regeneration in Ambystoma mexicanum
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)This present study examined tail regeneration in the Mexican salamander Ambystoma mexicanum, on a single cell level in vivo. The primary aim of this study was to understand where the cells were coming from to replace all ... -
Small islands and large biogeographic barriers have driven contrasting speciation patterns in Indo-Pacific sunbirds (Aves: Nectariniidae)
(2022)Birds of the Indo-Pacific have provided biologists with many foundationalinsights. This study presents evidence for strong phylogeographic structure in two sunbird species from the heart of this region, the olive-backed ... -
Snake venom potency and yield are associated with prey-evolution, predator metabolism and habitat structure
(PubMed Central, 2019)Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast ... -
Soil-transmitted helminth infections in Nigerian children aged 0-25 months
(2009)The objective of this cross-sectional study was to determine the prevalence and intensity of soil-transmitted helminths (STHs) in children aged 0?25 months and to identify the associated risk factors for Ascaris lumbricoides ... -
Spatial and temporal variability in the littoral macroinvertebrate communities of selected Irish lakes
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Five replicate samples were collected from five exposed stony shoreline sites in three low, mid and high alkalinity lakes within a narrow temporal window in order to assess the spatial variation in littoral invertebrate ... -
Spatio-temporal variability in the deposition of beach-cast kelp (wrack) and inter-specific differences in degradation rates
(Inter-Research Science Center, 2021)Coastal habitats dominated by marine macroalgae typically exhibit high rates of pri- mary productivity and play a key role in local and regional carbon cycles and stores. In temperate regions, large brown algae (i.e. ... -
Specialization and the road to academic success
(Ecological Society of America, 2011)The relative merits of focusing research on few areas of science versus generalizing across topics have important implications for how academics conduct science. Little is known, however, about how research breadth and ... -
Sporadic Cryptosporidium infection in Nigerian children: Risk factors with species identification
(2011)A cross-sectional study was conducted to investigate risk factors for sporadic Cryptosporidium infection in a paediatric population in Nigeria. Of 692 children, 134 (19?4%) were infected with Cryptosporidium oocysts. ... -
The stability of ecosystems under global environmental change
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2022)Through global environmental change, humans are modifying the planet at an unprecedented rate and scale, triggering the ongoing biodiversity and climate crises. Ecological stability and the consistency of nature s contributions ... -
Stable isotopes are quantitative indicators of trophic niche
(Wiley, 2019)Hette-Tronquart (2019, Ecol. Lett.) raises three concerns about our interpretation of stable isotope data in Sheppard et al. (2018, Ecol. Lett., 21, 665). We feel that these concerns are based on comparisons that are ... -
Strong context-dependent virulence in a host-parasite system: reconciling genetic evidence with theory
(Blackwell, 2003)1. Parasites can have dramatic effects on the ecology of their hosts. Such strong host-parasite interactions are the result of either parasites with generally high virulence, or generally benign parasites that nevertheless ... -
Susceptibility and mortality in honeybees (Apis mellifera) infested with the tracheal mite (Acarapis woodi)
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)The tracheal mite, Acarapis woodi (Rennie), is an obligate parasite of the honeybee. It was first discovered in 1919 by Rennie during his investigation into the widespread deaths of honeybee colonies in Europe in the early ... -
Sustainable harvesting of the ecosystem engineer Corallina officinalis for biomaterials
(2019)Macroalgae are of increasing interest for high-value biotechnological applications, but some seaweeds, such as coralline red algae, cannot be grown in cultivation cost-effectively. Wild harvesting of seaweeds, particularly ...
