Utilisation of brown trout by Acanthocephalus clavula (Acanthocephala) in brown trout (Salmo trutta) in an Irish lake: is this evidence of a host shift?
(2004)The population biology of the fish acanthocephalan Acanthocephalus clavula was described from 161 wild brown trout, Salmo trutta sampled over a two-year period in Clogher Lake in the west of Ireland. Overall prevalence of ... -
Procollagen Type I amino-terminal propeptide : pediatric reference data and relationship with procollagen type I carboxyl-terminal propeptide
(American Association for Clinical Chemistry, 2004)Type I collagen is the predominant collagen in bone and soft tissue. The rate of synthesis of type I collagen can be assessed by measuring plasma concentrations of the C-terminal (PICP) and N-terminal (PINP) propeptides ... -
Predisposition to ascariasis: patterns, mechanisms and implications
(2009)Ascaris lumbricoides, the human roundworm, is a remarkably infectious and persistent parasite. It is a member of the soil-transmitted helminths or geohelminths and infects in the order of 1472 million people worldwide. ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(2006)Ascaris suum and Ascaris lumbricoides exhibit an over-dispersed frequency distribution in their host populations in both the adult and larval stages. The impact of host factors on this observed distribution is still poorly ... -
The migration of Ascaris suum larvae, and the associated pulmonary inflammatory response in susceptible C57BL/6j and resistant CBA/Ca mice
(2007)Ascariasis is an important infection in humans (Ascaris lumbricoides) and pigs (Ascaris suum) and individuals appear to be predisposed to either heavy or light worm burdens. These extremes of susceptibility and resistance ... -
A murine model for cerebral toxocariasis: characterisation of host susceptibility and behaviour.
(2006)Toxocara canis, the parasitic roundworm of dogs, can infect a number of paratenic hosts, such as mice and humans, due to the widespread dissemination of its ova in the environment. In these paratenic hosts, larvae have ... -
Dose-dependent impact of larval Ascaris suum on host body weight in the mouse model
(2009)Ascaris lumbricoides and Ascaris suum are important helminth parasites of humans and pigs, respectively. Although it is now well established that the presence of mature adult worms in the host intestine contributes to ... -
Patterns of soil-transmitted helminth infection and impact of four-monthly albendazole treatments in preschool children from semi-urban communities in Nigeria: a double-blind placebo-controlled randomised trial.
(2009)BACKGROUND: Children aged between one and five years are particularly vulnerable to disease caused by soil-transmitted helminths (STH). Periodic deworming has been shown to improve growth, micronutrient status (iron and ... -
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 ... -
Identification of Mechanosensitive Genes during Embryonic Bone Formation.
(2008)Although it is known that mechanical forces are needed for normal bone development, the current understanding of how biophysical stimuli are interpreted by and integrated with genetic regulatory mechanisms is limited. ... -
Impacts of inbreeding on bumblebee colony fitness under field conditions
(BioMed Central, 2009)BACKGROUND: Inbreeding and the loss of genetic diversity are known to be significant threats to small, isolated populations. Hymenoptera represent a special case regarding the impact of inbreeding. Haplodiploidy may permit ... -
Developing bones are differentially affected by compromised skeletal muscle formation
(University of Edinburgh (datashare), 2010)Mechanical forces are essential for normal adult bone function and repair, but the impact of prenatal muscle contractions on bone development remains to be explored in depth in mammalian model systems. In this study, we ... -
Effects of retinoic acid excess on expression oh Hox 2.9 and Krox 20 and on morphological segmentation in the hindbrain of mouse embryos
(Nature Publishing Group, 1991)Mouse embryos were exposed to maternally administered RA on day 8.0 or day 7 3/4 of development, i.e. at or just before the differentiation of the cranial neural plate, and before the start of segmentation. On day 9.0, the ... -
Two domains of the human bZIP transcription factor TCF11 are necessary for transactivation

Gene expression analysis of canonical Wnt pathway transcriptional regulators during early morphogenesis of the facial region in the mouse embryo
(University of Edinburgh (datashare), 2009)Structures and features of the face, throat and neck are formed from a series of branchial arches that grow out along the ventrolateral aspect of the embryonic head. Multiple signaling pathways have been implicated in ... -
On the evolution of claustral colony-founding in ants
(Evolutionary Ecology Ltd, 2003)The dispersal and survival of offspring is a key step in an organism?s life history. In ants, the main strategy used to complete this step is known as independent colony-founding. Here, individual young queens leave their ... -
Activation of host constitutive immune defence by an intestinal trypanosome parasite of bumble bees
(Cambridge University Press, 2003)Many parasites have to survive the harsh environment of insect guts to complete their life-cycle. Important parasites of man and animals pass part of their life cycle in insect guts and hence understanding how insects ... -
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 ... -
Does size matter? Bumblebee behaviour and the pollination of Cytisus scoparius L. (Fabaceae)
(2000)The effects of forager body size and floral display size on pollinator behaviour were assessed in a relatively specialised plant-pollinator system. Cytisus scoparius, which has structurally complex, nectarless flowers is ... -
Building on IUCN regional red lists to produce lists of species of conservation priority: A model with Irish bees
(Society for Conservation Biology, 2007)A World Conservation Union (IUCN) regional red list is an objective assessment of regional extinction risk and is not the same as a list of conservation priority species. Recent research reveals the widespread, but incorrect, ...
