This longitudinal cohort study evaluated the diversity, commonality, and stability of Streptococcus mutans genotypes associated with dental caries history. Sixty-seven 5- and 6-yr-old children, considered as being at high caries risk, had plaque collected from baseline through 36 months for S. mutans isolation and genotyping using repetitive extragenic palindromic-PCR (4,392 total isolates). De...

BACKGROUND Genotyping of human papillomarvirus (HPV) is crucial for patient management in a clinical setting. This study accesses the combined use of broad-range real-time PCR and high-resolution melting (HRM) analysis for rapid identification of HPV genotypes. METHODS Genomic DNA sequences of 8 high-risk genotypes (HPV16/18/39/45/52/56/58/68) were subject to bioinformatic analysis to select ...

Clinical resistance to chemotherapy is one of the major problems in breast cancer treatment. In this study we analyzed possible impact of 22 polymorphic variants on the treatment response in 324 breast cancer patients. Selected genes were involved in FAC chemotherapy drugs transport (ABCB1, ABCC2, ABCG2, SLC22A16), metabolism (CYP1B1, CYP2C19, GSTT1, GSTM1, GSTP1, TYMS, MTHFR, DPYD), drug-induc...

BACKGROUND Matrix metalloproteinases, such as stromelysin-1, are implicated in the pathogenesis of coronary artery disease (CAD) and acute myocardial infarction (MI). A 5A/6A promoter polymorphism can regulate the transcription of the stromelysin-1 gene in an allele-specific manner. Evidence has been presented that the 6A allele is associated with the progression of coronary heart disease (CHD)...

Human papillomavirus (HPV) infection is a necessary factor in the development of cervical cancer. A new HPV screening method, "Human Papillomavirus Genotyping (HPG)", was developed to detect 29 HPV genotypes distribution in China. The utility of HPG was compared to Hybrid Capture 2 High-Risk HPV DNA test (HC2), and it was determined that the HPG test had been proven to be a more credible and se...

Background & aim: AIDS is one of the major public health challenges all over the world. Perceived risk is a significant predictor of high-risk behaviors related to AIDS. Women constitute more than half of the HIV patients, and the rate of female sex workers with AIDS is more than the rest of female population. Therefore, the present study aimed to evaluate AIDS risk perception and its related f...

BACKGROUND Little is known regarding the human papillomaviruses (HPV) genotypes prevalent in women in South Africa, a country with a high incidence of cervical cancer. OBJECTIVE To determine the prevalence and HPV genotypes in women with squamous abnormalities and normal cervixes participating in a community-based microbicide study. STUDY DESIGN A total of 159 cervical specimens, including ...
