HIV-1 Vif's principal function is to counter the antiretroviral activities of DNA-editing APOBEC3 cytidine deaminases. Unconstrained APOBEC3 activity introduces premature stop codons in HIV-1 genes and can lead to viral inactivation. To investigate the evolution and diversification of Vif over the HIV-1 pandemic and document evidence of APOBEC3-mediated pressure, we analyzed 4612 publicly available sequences derived from 10 dominant subtypes and circulating recombinant forms (CRFs) using the Hervé platform.

Peroxidase DNAzymes are single-stranded, stable G-quadruplexes structures that exhibit catalytic activity with cofactor hemin. This class of DNAzymes offers several advantages over traditional protein and RNA catalysts, including thermal stability, resistance to hydrolysis, and easy of synthesis in the laboratory. However, their use in medicine, biology, and chemistry is limited due to their low catalytic rates.

Malaria and hypertension are seemingly unrelated communicable and non-communicable diseases, both highly pervasive in the global south. There is a debate about the potential connection between these two disorders beyond any obvious factors. The emerging evidence suggests an emerging genetic selection pressure for hypertension in malaria-endemic regions.

Objective: This study aims to identify potential lipid biomarkers and metabolic pathways associated with oral cancer (OC). Then to establish and evaluate disease classification models capable of distinguishing OC patients from healthy controls.
Methods: A total of 41 OC patients and 41 controls were recruited from a hospital in Southeast China to examine the serum lipidomics by Ultra-high Performance Liquid Chromatography Q Exactive Mass Spectrometry (UHPLC-QE-MS).
