OBJECTIVE To assess human papillomavirus (HPV) vaccination coverage after demonstration projects conducted in India, Peru, Uganda and Viet Nam by PATH and national governments and to explore the reasons for vaccine acceptance or refusal. METHODS Vaccines were delivered through schools or health centres or in combination with other health interventions,(More)
While the Mre11-Rad50-Nbs1 (MRN) complex has known roles in repair processes like homologous recombination and microhomology-mediated end-joining, its role in nonhomologous end-joining (NHEJ) is unclear as Saccharomyces cerevisiae, Schizosaccharomyces pombe, and mammals have different requirements for repairing cut DNA ends. Most double-strand breaks (DSBs)(More)
BACKGROUND Limited human papillomavirus (HPV) related knowledge might be a barrier to future vaccine acceptance. From 2008-2010, PATH conducted an HPV vaccination demonstration project in partnership with the government immunization program in Vietnam, which included awareness campaigns prior to vaccination. OBJECTIVE To assess and compare knowledge and(More)
The reduction of a redox-active ligand is shown to drive reversible switching of a Cu(I) [2]pseudorotaxane ([2]PR(+)) into the reduced [3]pseudorotaxane ([3]PR(+)) by a bimolecular mechanism. The unreduced pseudorotaxanes [2]PR(+) and [3]PR(2+) are initially self-assembled from the binucleating ligand, 3,6-bis(5-methyl-2-pyridine)-1,2,4,5-tetrazine(More)
Chronic viral infections (e.g., HIV, HBV, HCV) represent a significant source of morbidity and mortality with over 500 million people infected worldwide. Dendritic cells (DCs) and macrophages are key cell types for productive viral replication and persistent systemic infection. We demonstrate that the plant virus cowpea mosaic virus (CPMV) displays tropism(More)
Sequencing of a cadmium resistance operon from a Staphylococcus aureus ATCC12600 plasmid revealed that it is identical to a cadCA operon found in MRSA strains. Compared to plasmid-cured and cadC-mutant strains, cadC-positive ATCC12600 cells had increased resistance to cadmium (1 mg ml(-1) cadmium sulfate) and zinc (4 mg ml(-1) zinc sulfate), but not to(More)
