BACKGROUND Cervical cancer is the second most common cancer in women worldwide. Infection with some genotypes of human papillomavirus is the most important risk factor associated with cervical cancer. OBJECTIVE The aim of this study was to determine the prevalence and genotypes of HPV in China, and to evaluate the correlation between viral load of high(More)
Human papillomavirus type 16 (HPV16) has a number of intratypic variants; each has a different geographical distribution and some are associated with enhanced oncogenic potential. Cervical samples were collected from 223 cervical cancer patients and from 196 age-matched control subjects in China. DNA samples were amplified by using primers specific for the(More)
Human leukocyte antigen (HLA) class II alleles have been associated with an increased or decreased risk of developing cervical cancer through infection with oncogenic forms of human papillomavirus (HPV). To verify whether HLA class II allelic polymorphism is related to cervical cancer in China, 133 cervical cancers and 98 healthy controls were analyzed for(More)
Cervical cancer is strongly associated with the infection by oncogenic forms of human papillomavirus (HPV). Although most women are able to clear HPV infection, some develop persistent infections that may lead to cancer, implying genetic susceptibility factors for malignant progression. To verify whether HLA class II DQB1 polymorphism is related to cervical(More)
In this review, we outline examples that illustrate the design criteria for achieving macromolecular assemblies that incorporate a combination of two or more chemical, physical or biological stimuli-responsive components. Progress in both fundamental investigation into the phase transformations of these polymers in response to multiple stimuli and their(More)
Self-assembly of random copolymers has attracted considerable attention recently. In this feature article, we highlight the use of random copolymers to prepare nanostructures with different morphologies and to prepare nanomaterials that are responsive to single or multiple stimuli. The synthesis of single-chain nanoparticles from random copolymers and their(More)
Infection with human papillomavirus type 16 (HPV16) confers a high risk for the development of cervical cancer. Variants of this virus may interact differentially with host genetic factors, possibly affecting the disease pathogenesis. This study was designed to investigate the association between HPV16 E6 variants and human leukocyte antigen (HLA)(More)
Antibody-drug conjugates have attracted a great amount of attention as a therapeutic strategy for diseases where targeting specific tissues and cells are critical components, such as in cancer therapy. Although promising, the number of approved ADC drugs is relatively limited. This emanates from the challenges associated with generating the conjugates and(More)
We report a series of novel O-(substituted benzyl) phosphoramidate prodrugs of 5-fluoro-2'-deoxyuridine for the treatment of hepatocellular carcinoma. Through structure optimization, the o-methylbenzyl analog (1t) was identified as an orally bioavailable and liver-targeted lead compound. This lead prodrug is well-tolerated at a dose up to 3 g/kg in Kuming(More)
Dynamic exchange of guest molecules, encapsulated in host assemblies, is a phenomenon in supramolecular chemistry that has important implications in several applications. While the mechanism of exchange in micellar assemblies has been previously investigated, the effect of host and guest environment upon the guest-exchange dynamics has received little(More)
