Expression of the mouse labial-like homeobox-containing genes, Hox 2.9 and Hox 1.6, during segementation of the hindbrain
(Company of Biologists, 1991)The sequence of a mouse Hox 2.9 cDNA clone is presented. The predicted homeodomain is similar to that of the Drosophila gene labial showing 80 % identity. The equivalent gene in the Hox 1 cluster is Hox 1.6 which shows ... -
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 ... -
The regulation of Krox-20 expression reveals important steps in the control of peripheral glial cell development.
(Company of Biologists, 1996)The zinc finger transcription factor gene Krox-20 is expressed in Schwann cells and is required for the myelination of peripheral nerves. We show that the regulation of Krox-20 expression in peripheral glial cells reveals ... -
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 ... -
Interaction of the CNC-bZIP factor TCF11/LCR-F1/Nrf1 with MafG: binding-site selection and regulation of transcription
(1998)We have previously shown that the widely expressed human transcription factor TCF11/LCR-F1/Nrf1 interacts with small Maf proteins and binds to a subclass of AP1-sites. Such sites are required for b-globin 54 DNase I ... -
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 public health importance of Ascaris lumbricoides
(2000)Numerous studies have shown that anthelminthic treatment can be effective in improving growth rates when given to malnourished children with ascariasis. Recent investigations have also indicated that Ascaris infections can ... -
The public health significance of Trichuris trichiura
(2000)An estimated 1049 million persons harbour T. trichiura, including 114 million preschool-age children and 233 million school-age children. The prevalence of T. trichiura is high and may reach 95% in children in many parts ... -
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 ... -
Condition-dependent expression of virulence in a trypanosome infecting bumblebees
(Blackwell, 2000)Parasite virulence affects both the temporal dynamics of host-parasite relationships and the degree to which parasites regulate host populations. If hosts can compensate for parasitism, then parasites may exhibit ... -
The influence of inoculum size and time post-infection on the number and position of Toxocara canis larvae recovered from the brains of outbred CD1 mice
(2001)Outbred CD1 mice were administered doses of 1000 and 3000 Toxocara canis eggs and postmortem took place on days 7, 42 and 120 post-infection. Mice were killed by cervical dislocation and brains were sagitally bisected and ... -
Two domains of the human bZIP transcription factor TCF11 are necessary for transactivation

The relationship between three intensity levels of Toxocara canis larvae in the brain and effects on exploration, anxiety, learning and memory in the murine host
(2001)Outbred LACA mice were administered low (100 ova), medium (1000 ova), high (3000 ova) and trickle (4?250 ova) doses of Toxocara canis ova and the effect of infection was examined with respect to the number of larvae recovered ... -
Toxocara in the mouse : A model for parasite-altered host behaviour ?
(2001)The objective of this paper is to critically evaluate the significance of parasite-altered host behaviour in the Toxocara mouse model particularly in the light of the Manipulation Hypothesis. Murine behaviours were examined ... -
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 ... -
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, ... -
A colony-level response to disease control in a leaf-cutting ant
(Springer Verlag, 2002)Parasites and pathogens often impose significant costs on their hosts. This is particularly true for social organisms, where the genetic structure of groups and the accumulation of contaminated waste facilitate disease ... -
Comparison of the macroparasite communities of stocked and wild trout (Salmo trutta) from the West of Ireland
(2002)The aim of the present study was to compare the helminth infra and component communities of wild and stocked brown trout in Lough Feeagh, in the west of Ireland, and also to examine the establishment and development of ... -
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 ...
