Cystic fibrosis (CF) is a common recessive genetic disease caused by mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. More than 1800 different mutations have been described to date. Here, we report 3 novel mutations in CFTR in 3 Italian CF patients. To detect and identify 36 frequent mutations in Caucasians, we used the INNO-LiPA CFTR19 ...

OBJECTIVE To explore the genotype distribution of high-risk human papillomavirus (HR-HPV) and its attribution to different grades of cervical lesions in rural China, which will contribute to type-specific HPV screening tests and the development of new polyvalent HPV vaccines among the Chinese population. METHODS One thousand two hundred ninety-two subjects were followed based on the Shanxi Pr...

BACKGROUND & OBJECTIVES Multidrug resistant (MDR) tuberculosis (TB) is a problem of increasing importance in the world due to limited treatment options. Resistance to rifampicin results from nucleotide changes in the gene encoding the beta subunit of the RNA polymerase (rpoB) of Mycobacterium tuberculosis. Rifampicin resistance is considered as a marker for MDR TB. The nature and frequency of m...

BACKGROUND Comparison and evaluation of molecular diagnostic assays for the detection and quantification of hepatitis C virus (HCV) RNA have been limited by the lack of RNA controls and calibrators. Armored RNA technology is a means for producing RNA that is completely protected from plasma ribonucleases. This method produces recombinant pseudoviral particles that are noninfectious and contain ...

Quick and accurate genotyping of hepatitis C virus (HCV) is becoming increasingly important for clinical management of chronic infection and as an epidemiological marker. Furthermore, the incidence of HCV infection with mixed genotypes has clinical significance that is not addressed by most genotyping methods. We have developed a fluorescence-based genotyping assay called primer-specific extens...

Objective: To explore the genotype distribution of high-risk human papillomavirus (HRHPV) and its attribution to different grades of cervical lesions in rural China, which will contribute to type-specific HPV screening tests and the development of new polyvalent HPV vaccines among the Chinese population. Methods: One thousand two hundred ninety-two subjects were followed based on the Shanxi Pro...

Persistent infection with oral HPV16 is believed to drive the development of most oropharyngeal cancers. However, patterns of oral HPV16 persistence remain understudied, particularly among HIV-negative individuals. Oral HPV16 persistence was evaluated among 1,626 participants of the HPV Infection in Men (HIM) Study. Twenty-three oral HPV16-positive men who provided an oral gargle sample on ≥2 s...

OBJECTIVES High-risk human papilloma virus (HPV) types stimulate degradation and deactivation of protein associated with the p53 tumour suppressor gene via the ubiquitin-dependent pathway. For a long time, changes of the p53 tumour suppressor gene have been correlated with poor clinical outcome in patients with superficial bladder cancer. We aimed to study the association between presence of (h...

For optimal antiviral therapy, the hepatitis C virus (HCV) genotype needs to be determined, as it remains a strong predictor of sustained viral response. In this study, we assessed the number of HCV genotyping results that could not be determined using the commercially available line probe assay (LiPA) (Versant hepatitis C virus genotype 2.0 assay) in a large international panel of samples from...

conclusions the present clinical study suggests that the transmission of an hbv genotype other than genotype d, namely hbv genotype g, is possible in turkey. epidemiological and clinical information on genotype g infection is currently limited, and this is most likely due to its low prevalence throughout the world. therefore, it may be important to determine the epidemiologic and molecular char...
