Parasitic nematodes are of medical and veterinary importance, adversely affecting human health and animal welfare. Ascaris suum is a gastrointestinal parasite of pigs; in addition to its veterinary significance it is a good model of the human parasite Ascaris lumbricoides, estimated to infect approximately 1.4 billion people globally. Anthelmintic drugs are(More)
Although the neurotoxicity of lead exposure is well documented, the cellular and molecular mechanisms underlying lead neurotoxicity have not been well defined. We have investigated the effect of lead on nerve growth factor (NGF)-induced neurite outgrowth in PC12 cells and the role in this process of extracellular signal regulated protein kinase (ERK), a key(More)
Large inter- and intra-individual variations exist in breastmilk composition, yet factors associated with these variations in the short-term are not well understood. In this study, the effects of breastfeeding on breastmilk cellular and biochemical content were examined. Serial breastmilk samples (∼5 mL) were collected from both breasts of breastfeeding(More)
Only a few novel classes of antiparasitic drugs have emerged over the last few decades, reflecting the difficulties associated with bringing a safe, effective molecule to market. In recent years, the screening paradigm has shifted from empirical whole parasite screening towards mechanism-based high throughput screening. This approach requires investment in(More)
