Association between vitamin D receptor gene polymorphisms and fibrosis susceptibility in Greek patients with HCV infection.

Introduction: Hepatitis C virus (HCV) infection is a prime cause of chronic hepatitis worldwide, that often silently progresses to fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Notably, the majority of individuals infected with HCV develop symptoms at late stages, often associated with liver damage that cannot revert after virus clearance. Thus, current antiviral therapy alone is rather insufficient to eliminate the global burden of HCV in the near future.

Defining virus-carrier networks that shape the composition of the mosquito core virome of a local ecosystem.

Mosquitoes are the most important vectors of emerging infectious diseases. During the past decade, our understanding of the diversity of viruses they carry has greatly expanded. Most of these viruses are considered mosquito-specific, but there is increasing evidence that these viruses may affect the vector competence of mosquitoes.

Dissecting the Species-Specific Virome in of Thrace.

Biting midges () are vectors of arboviruses of both veterinary and medical importance. The surge of emerging and reemerging vector-borne diseases and their expansion in geographical areas affected by climate change has increased the importance of understanding their capacity to contribute to novel and emerging infectious diseases. The study of virome is the first step in the assessment of this potential.

ZWA: Viral genome assembly and characterization hindrances from virus-host chimeric reads; a refining approach.

Viral metagenomics, also known as virome studies, have yielded an unprecedented number of novel sequences, essential in recognizing and characterizing the etiological agent and the origin of emerging infectious diseases. Several tools and pipelines have been developed, to date, for the identification and assembly of viral genomes. Assembly pipelines often result in viral genomes contaminated with host genetic material, some of which are currently deposited into public databases.

A main event and multiple introductions of SARS-CoV-2 initiated the COVID-19 epidemic in Greece.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus responsible for the coronavirus disease 2019 (COVID-19) pandemic. Chains of infections starting from various countries worldwide seeded the outbreak of COVID-19 in Athens, capital city of Greece. A full-genome analysis of isolates from Athens' hospitals and other healthcare providers revealed the variety of SARS-CoV-2 that initiated the pandemic before lockdown and passenger flight restrictions.
