ABSTRACT Hepatitis D virus (HDV) is a satellite of hepatitis B (HBV) for transmission and propagation infects nearly 20 million people worldwide. The HDV genome compact circular single-stranded RNA with extensive intramolecular complementarity. Despite its different epidemiological pathological patterns, the variability geographical distribution are limited to three genotypes two subtypes that have been characterized date. Phylogenetic reconstructions based on delta antigen gene full-length...

Hepatitis delta virus (HDV) is responsible for the most severe form of acute and chronic viral hepatitis. We previously proposed that Deltavirus genus composed eight major clades. However, few sequences were available to confirm this classification. Moreover, little known about structural functional consequences HDV variability. One practical consequence failure quantification assays properly detect or quantify plasmatic RNA. Between 2001 2014, 2,152 strains prospectively collected genotyped...

Multiple sclerosis (MS) is a common neurological disease affecting the optic nerve, directly or indirectly, through transsynaptic axonal degeneration along visual pathway. New ophthalmological tools, arguably most important being optical coherence tomography (OCT), could prove paramount in redefining MS diagnoses and shaping their follow-up protocols, even when nerve not involved.A prospective clinical study was conducted. In total, 158 eyes from patients previously diagnosed with relapsing...
