BACKGROUND Age prevalence curves for areas in which schistosomiasis is endemic suggest that humans develop partial immunity to reinfection beginning in early adolescence. We conducted a 2-year longitudinal study to determine whether children infected with Schistosoma mansoni develop protection-related immune responses after treatment with praziquantel and… (More)
Arrestins are regulatory proteins that bind specifically to ligand-activated phosphorylated G protein-coupled receptors to terminate G protein-mediated signaling, cause the internalization of the receptor-arrestin complex, and initiate additional intracellular signaling cascades. Multiple lines of evidence suggest that arrestin normally exists in an… (More)
BACKGROUND Intracytoplasmic sperm injection (ICSI) is a component of infertility treatment often employed when conventional in vitro fertilization is unlikely to be successful. Despite good clinical results with ICSI, the procedure is typically associated with degeneration of a significant percentage (approximately 10%) of the treated oocytes. The cause of… (More)
An aromatic peptide amphiphile was designed for delivery of the signaling gas H2S. The peptide self-assembled in water into nanofibers that gelled upon charge screening. The non-toxic gel slowly released H2S over 15 hours, and the presence of H2S in endothelial cells was verified using a fluorescent H2S probe.
The discussion regarding how to address requests for help with grammar and sentence-level concerns has been an ongoing conversation throughout writing center literature. The general consensus among administrators and tutor-scholars within in the field is to move away from a product-oriented focus towards one that is more process-oriented, preferring to… (More)
BACKGROUND Schistosomiasis is a disease of major public health importance in sub-Saharan Africa. Immunoregulation begins early in schistosome infection and is characterized by hyporesponsiveness to parasite and bystander antigens, suggesting that a schistosome infection at the time of immunization could negatively impact the induction of protective vaccine… (More)
