OBJECTIVES Concerns have been raised that human papillomavirus (HPV) vaccination could lead to altered risk perceptions and an increase in risky sexual behaviors among adolescents. The aim of this study was to assess whether adolescent risk perceptions after the first vaccine dose predicted subsequent sexual behaviors. METHODS Young women 13 to 21 years(More)
Principal components analysis (PCA) has been successfully used to correct for population stratification in genome-wide association studies of common variants. However, rare variants also have a role in common disease etiology. Whether PCA successfully controls population stratification for rare variants has not been addressed. Thus we evaluate the effect of(More)
The ability to transport a large quantity of drug molecules into cytosolic compartments of cancer cells has powerful implications in modern molecular therapeutics because the sites of action of the drugs are often cytosolic organelles. Furthermore, direct cytosolic delivery might offer a means to evade efflux transporters, such as multidrug-resistance(More)
Naringenin, one of the most abundant flavonoids in citrus, grapefruits and tomatoes, has been used as a traditional anti-inflammatory agent for centuries. However, the molecular mechanism of naringenin in intestinal inflammation remains unknown so far. The present study investigated a molecular basis for the protective effect of naringenin in dextran(More)
Targeted activation of pregnane X receptor (PXR) in recent years has become a therapeutic strategy for inflammatory bowel disease. Chrysin is a naturally occurring flavonoid with anti-inflammation activity. The current study investigated the role of chrysin as a putative mouse PXR agonist in preventing experimental colitis. Pre-administration of chrysin(More)
Targeted delivery of intracellularly active diagnostics and therapeutics in vivo is a major challenge in cancer nanomedicine. A nanocarrier should possess long circulation time yet be small and stable enough to freely navigate through interstitial space to deliver its cargo to targeted cells. Herein, it is shown that by adding targeting ligands to(More)
The objective of the present study was to explore the common and specific metabolic alterations of hepatocellular carcinoma (HCC) infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). Serum profiling data revealed that the two HCC groups shared a mainly similar metabolic profile, providing a basis for investigating their common tumor(More)
Constructed wetlands are ecosystems that use plants and microorganisms to remediate pollution in soil and water. In this study, two parallel pilot-scale vertical flow wetland and horizontal flow wetland (VF-HF) systems were implemented to investigate the treatment performance and microorganism community structure in the secondary effluent of an industrial(More)
Performances of microbial fuel cells (MFCs) were studied at 5–10 and 25–30 °C. Results showed stable operation of the MFCs at low temperatures with only slight reductions of voltage and power generation (11 versus 14 % for double-chamber MFC, while 14 versus 21 % for single-chamber MFC, 1,000 Ω) compared to those at mesophilic temperatures. MFCs operated at(More)
OBJECTIVES The aims of this study were to examine mothers' intention to vaccinate their daughters and themselves against human papillomavirus and to determine which demographic, behavioral, and attitudinal factors were associated with intention to vaccinate daughters. METHODS We surveyed 10,521 US mothers, all nurses, between June 2006 and February 2007.(More)
