Prevalence rate of high-grade cytological lesions of the cervix in women aged under 25 years in French Guiana.

Introduction: The incidence of cervical cancer in French Guiana is among the highest worldwide. It ranks 5th among all cancers and is the 2nd most common cancer in women after breast cancer. The primary objective of this study was to establish the proportion of high-grade cytological lesions of the cervix in women under 25 years of age who underwent a cervico-uterine smear (CUS) in French Guiana over a 10-year period.

Role of homologous recombination/recombineering on human adenovirus genome engineering: Not the only but the most competent solution.

Adenoviruses typically cause mild illnesses, but severe diseases may occur primarily in immunodeficient individuals, particularly children. Recently, adenoviruses have garnered significant interest as a versatile tool in gene therapy, tumor treatment, and vaccine vector development. Over the past two decades, the advent of recombineering, a method based on homologous recombination, has notably enhanced the utility of adenoviral vectors in therapeutic applications.

Longitudinal Analysis of Binding Antibody Levels Against 39 Human Adenovirus Types in Sera from 60 Regular Blood Donors from Greifswald, Germany, over 5 Years from 2018 to 2022.

Adenoviruses are important human pathogens that are widespread and mainly associated with respiratory and gastrointestinal infections. In a previous study on human adenovirus (HAdV) seroprevalence, we observed reduced binding antibody levels against a range of HAdV types in sera collected from students in 2021 compared to sera collected before the SARS-CoV-2 pandemic. In this follow-up study, we wanted to verify this observation in a cohort of regular blood donors for whom serial samples were available.

ADEVO: Proof-of-concept of adenovirus-directed EVOlution by random peptide display on the fiber knob.

Directed evolution of viral vectors involves the generation of randomized libraries followed by artificial selection of improved variants. Directed evolution only yielded limited results in adenovirus (AdV) engineering until now, mainly due to insufficient complexities of randomized libraries. Meanwhile, clinical applications of AdVs as gene therapy or oncolytic vectors are still hampered by the predetermined tropism of natural types.

Expression and prognosis of DSG-2, CXADR, CD46 in head and neck squamous cell carcinoma.

Objectives: Investigating the expression and prognostic significance of adenovirus receptors DSG-2, CXADR and CD46 in head and neck cancer.

Methods: 104 patients with HNSCC (77 OPSCC, 27 LSCC) were retrospectively included in the study. Immunohistochemical staining was performed on all selected slides to detect the expression of DSG-2, CXADR, CD46 and the immunoreactive score (IRS) was determined from the number of positively stained tumor cells and their staining intensity.
