Article Synopsis
  • Human Papillomaviruses (HPV) have co-evolved with humans, being the main cause of cervical cancer, particularly HPV16, which is the most oncogenic high-risk type.
  • The E6/E7 proteins of high-risk HPVs, especially HPV16, are critical for cervical cancer development as they interact with important cellular proteins like p53 and pRb, influencing viral persistence and oncogenesis.
  • New methods for analyzing HPV mutations and alterations in the viral genome could enhance cervical cancer screening processes in France.

Background: ADAS-3D software elaborates cardiac magnetic resonance (CMR) images to obtain a quantitative evaluation of dense scar and border zone (BZ), including BZ channels, which can be useful for ventricular tachycardia ablation and risk stratification. However, most prior reports with ADAS-3D used flexible thresholds (60% ± 5% and 40% ± 5% of maximum pixel signal intensity) to define dense scar and BZ. The impact of such variations of the threshold values on the measurements obtained with ADAS-3D is unknown.

The AAA ATPase valosin containing protein (VCP) is essential for cell and organ homeostasis, especially in cells of the nervous system. As part of a large network, VCP collaborates with many cofactors to ensure proteostasis under normal, stress, and disease conditions. A large number of mutations have revealed the importance of VCP for human health.

Point-of-care syndromic PCR (POC SPCR) assays are useful tools for the rapid detection of the most common causative agents of community-acquired infections responsible for meningitis and encephalitis infections. We evaluated the performance characteristics of the new QIAstat-Dx Meningitis/Encephalitis panel (QS) compared to the laboratory reference methods and the POC SPCR Biofire FilmArray Meningitis Encephalitis Panel (FA). Viral (Enterovirus, Parechovirus, HSV-1, HSV-2, HHV-6, VZV) and bacterial ( K1, , , encapsulated , , , , ) pathogens were suspended at low concentrations and tested with the POC SPCR systems.
