A splice donor in influences keratinocyte immortalization by beta-HPV49.

Human papillomaviruses (HPV) from the genus beta have been implicated in the development of cutaneous squamous cell cancer in and organ transplant patients. In contrast to alpha-high-risk HPV, which cause ano-genital and oropharyngeal cancers, beta-HPV replication is not well understood. The beta-HPV49 transcriptome was analyzed by RNA sequencing using stable keratinocyte cell lines maintaining high levels of extrachromosomally replicating E8- genomes, which can be established due to a lack of the viral E8^E2 repressor protein.

Clinical characteristics of dengue virus infections in Karachi from 2019 to 2023: a cross-sectional study.

Dengue fever is a vector-borne, acute, febrile, and self-limiting systemic viral infection that affects tropical and subtropical regions, including Pakistan. Karachi has a significant burden of Aedes aegypti and Aedes albopictus due to suitable breeding sites, weather, and rapid and unplanned urbanization of squatter areas. The country has limited surveillance studies on circulating serotypes of the dengue virus and the patient's clinical features evolving over temporal changes.

Molecular characterization of human adenoviruses associated with pediatric respiratory infections in Karachi, Pakistan.

Human adenoviruses (HAdVs) are a diverse group of viruses associated with respiratory infections in humans worldwide. However, there is a lack of research on the genetic diversity and epidemiology of HAdVs in Pakistan. This study characterized HAdVs in pediatric patients with respiratory tract infections in Karachi, Pakistan, between 2022 and 2023.

Prevalence of Human Papillomavirus (HPV) and HPV Type Distribution in Penile Samples in Young Men in Denmark: Results 10 Years After Implementation of a Girls-Only HPV Vaccination Program.

Background: In Denmark, a girls-only human papillomavirus (HPV) vaccination program was initiated in 2008-2009. The study aim was to assess the HPV prevalence and type distribution in younger men prior to HPV vaccination in men.

Methods: The study population was younger men who attended information days regarding military service.

Evaluation of an automated real-time transcription-mediated amplification (TMA) assay for detection and quantification of cytomegalovirus DNA in different clinical specimens.

Background: Reliable and fast detection and quantification of human cytomegalovirus (CMV) DNA in various diagnostic specimens is essential for care of immunocompromised or congenitally infected individuals.

Objectives: To evaluate the analytical and clinical performance of the Panther Aptima® CMV (Hologic) quantitative real-time transcription mediated amplification (TMA) assay.

Study Design: Performance of the TMA assay run on the Hologic Panther Fusion was analysed for 32 proficiency testing samples and 21 quantitative reproducibility panel samples; additionally, we compared results of TMA assay and routine quantitative real-time PCR assays ("PCR-A"= Biomérieux CMV R-gene® or "PCR-B"= Laboratory-developed CMV-PCR) in 518 diagnostic specimens (254 plasma, 120 EDTA whole blood, 43 urine, 45 amniotic fluid and 56 breast milk) at two university hospital laboratories.
