SARS-CoV-2 belongs to the genus Beta of the Coronaviridae family of enveloped single-stranded, positive-sense ribonucleic acid (RNA) with a genome length of 30,000bp. The virion is composed of various non-structural (RNA dependent RNA polymerase also known as RdRp) and structural proteins such as Spike (S), Nucleocapsid (N), Matrix (M), and Envelope (E) proteins.

In this study, the safety and efficacy of liver biopsies performed by endoscopic ultrasound (EUS-LB) were compared with those performed via the traditional percutaneous route at our Medical Center between January 2018 and August 2019.

Although gastrointestinal stromal tumors, GISTs, are the most common neoplasms arising from the gastrointestinal mesenchyme, they represent less than 1% of all digestive tumors. Its incidence has increased in recent years, probably due to improved diagnostic methods. It is currently known that GIST is the most common sarcoma. It originates from interstitial cells of Cajal and depends on the transcription factor ETV-1. These are neoplasms associated with molecular alterations and some mutations.

Candida spp. are often detected from fungal cultures or mycobiome analysis of respiratory secretions, but are not usually treated since, even if detected persistently, the presence is assumed to be benign colonization unless invasive candidiasis in deeply immunocompromised subjects is suspected.

Molecular docking approaches explore the receptor-ligand conformations within the binding sites of macromolecular targets [1]. Structure-based drug discovery is widely used by the scientific community in Medicinal Chemistry to estimate the ligand-receptor binding free energy by evaluating critical phenomena involved in the intermolecular recognition process [2,3].
