this study was conducted to find out the prevalence, viral load and co-infection of hbv and hcv infection among patients seeking to hospital care in mashhad, iran. a total of 402 samples (349 samples for hbv and 53 for hcv) were received and were screened for hepatitis b and c during 2004 to 2014. viral loads of hbv dna and hcv rna were quantified by real-time pcr. among 349 collected samples, ...

aim : the aim of this study was to compare alternatives methods for analysis of zero inflated count data and compare them with simple count models that are used by researchers frequently for such zero inflated data. background : analysis of viral load and risk factors could predict likelihood of achieving sustain virological response (svr). this information is useful to protect a person from ac...

OBJECTIVES To examine the relation between symptoms, initial viral load, and viral load set point in primary HIV infection (PHI). DESIGN Prospective cohort of patients with preseroconversion or recent seroconversion HIV infection (typically <60 days) in San Francisco. METHODS Subjects were questioned about 21 potential PHI symptoms at enrollment and were subsequently followed with viral loa...

  Objective(s): HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV- I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated.   Materials and...

Background: Despite of isolation of Xenotropic murine leukaemia virus-related virus (XMRV) from the patients acquired prostate cancer in 2006 and patients with chronic fatigue syndrome in 2009, there have been controversial findings about its potential role in human diseases and frequencies in different population groups. In the present study, we aimed to determine the frequency of XMRV genome ...

Studies investigating human papillomavirus (HPV) viral load as a risk factor in the development of squamous intraepithelial lesions (SILs) and cancer have often yielded conflicting results. These studies used a variety of HPV viral quantitation assays [including the commercially available hybrid capture 2 (HC 2) assay], which differ in their ability to account for differences in cervical cell c...

Background. The etiologic inference of identifying a pathogen in the upper respiratory tract (URT) of children with pneumonia is unclear. To determine if viral load could provide evidence of causality of pneumonia, we compared viral load in the URT of children with World Health Organization-defined severe and very severe pneumonia and age-matched community controls. Methods. In the 9 developi...
