Cooperation and the evolution of intelligence
(2012)The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions ... -
Validation and use of a parametric model for projecting cystic fibrosis survivorship beyond observed data: a birth cohort analysis
(BMJ Group, 2011-07-22)Background: The current lifetable approach to survival estimation is favoured by CF registries. Recognising the limitation of this approach, we examined the utility of a parametric survival model to project birth cohort ... -
The role of Intelectin-2 in resistance to Ascaris suum lung larval burdens in susceptible and resistant mouse strains
(2011)The underlying mechanism of predisposition to Ascaris infection is not yet understood but host genetics are thought to play a fundamental role. We investigated the association between the Intelectin-2 gene and resistance ... -
The effects of season, habitat, hydroperiod and water chemistry on the distribution of turlough aquatic invertebrate communities
(University of Dublin, Trinity College, 2009)The aim of this study was to investigate the effects of season, habitat, hydroperiod and water chemistry on the distribution of turlough aquatic invertebrate communities. Twenty-two turloughs, selected as representative ... -
Abnormal Notochord Branching is Associated with Foregut Abnormalities in an Adriamycin Treated Mouse Model
(University of Edinburgh (datashare), 2011)Oesophageal atresia (OA) and tracheooesophageal fistula (TOF) are relatively common human congenital malformations of the foregut where the oesophagus does not connect with the stomach and there is an abnormal connection ... -
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 evolutionary pathway to obligate scavenging in Gyps vultures
(PLoS, 2011)The evolutionary pathway to obligate scavenging in Gyps vultures remains unclear. We propose that communal roosting plays a central role in setting up the information transfer network critical for obligate scavengers in ... -
Biophysical stimuli induced by passive movements compensate for lack of skeletal muscle during embryonic skeletogenesis
(University of Edinburgh (datashare), 2011)In genetically modified mice with abnormal skeletal muscle development, bones and joints are differentially affected by the lack of skeletal muscle.We hypothesise that unequal levels of biophysical stimuli in the ... -
Genetic influence on the kinetics and associated pathology of the early stage (intestinal-hepatic) migration of Ascaris suum in mice
(2010)The generative mechanism(s) of aggregation and predisposition to Ascaris lumbricoides and A. suum infections in their host population are currently unknown and difficult to elucidate in humans and pigs for ethical/logistical ... -
Ascaris and ascariasis
(2011)Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed ... -
Investigating the underlying mechanism of resistance to Ascaris infection
(2011)The generative mechanism(s) of predisposition to Ascaris infection are currently unknown. While many factors play a role in interindividual infection intensity, much focus has been placed on the host's immunological response ... -
Impact of repeated four-monthly anthelmintic treatment on Plasmodium infection in preschool children: a double-blind placebo-controlled randomized trial
(2010)Background: Helminth infections can alter susceptibility to malaria. Studies need to determine whether or not deworming programs can impact on Plasmodium infections in preschool children. Methods: A double-blind ... -
Cellular inhibitor of apoptosis (cIAP1) is down-regulated during retinal ganglion cell (RGC) maturation.
(Elsevier, 2010)Apoptosis, is the main type of cell death that occurs in ageing and neurodegenerative disease, such as glaucoma. This study therefore characterises the expression profile of caspases (pro-apoptosis) and inhibitors of ... -
Development of an in vitro culture method for cells and tissues from the zebra mussel (Dreissena polymorpha)
(Springer, 2009)Despite the successful transfer of mammalian in vitro techniques for use with fish and other vertebrates, little progress has been made in the area of invertebrate tissue culture. This paper describes the development of ... -
Do differences in the administrative structure of populations confound comparisons of geographic health inequalities?
(2010)Background: Geographical health inequalities are naturally described by the variation in health outcomes between areas (e.g. mortality rates). However, comparisons made between countries are hampered by our lack ... -
Contamination of the hair of owned dogs with the eggs of Toxocara spp
(2010)Toxocara canis is one of the most common gastrointestinal helminthes of dogs. Humans can become infected through ingestion of infective eggs, Infection often causes few symptoms but in rare cases blindness can occur. It ... -
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 ... -
Community study of toxoplasma antibodies in urban and rural schoolchildren aged 4 to 18 years.
(BMJ Publishing Group, 1997)To estimate the prevalence of toxoplasma antibodies in schoolchildren and their association with clinical and environmental data, antibody titres were measured in 1276 children aged 4 to 18 years attending primary and ... -
Natural immunity to Ascaris lumbricoides associated with IgE antibody to ABA-1 allergen and inflammatory indicators in children
(American Society for Microbiology, 1999)Children putatively immune to the large roundworm Ascaris lumbricoides were identified in an area of Nigeria where infection is hyperendemic. Immunity was associated with higher levels of serum ferritin, C-reactive protein, ... -
The influence of mouse strain, infective dose and larval burden in the brain on activity in Toxocara-infected mice
(2001)Outbred LACA mice and inbred NIH mice were administered low (100 ova), medium (1000 ova), high (3000 ova) and trickle (4x250 ova) doses of Toxocara canis ova and the effect of infection on activity was examined with respect ...
