Analysis of SARS-CoV-2 interactions with the Vero cell lines by scanning electron microscopy.

In this study, scanning electron microscopy (SEM) was used to study the cell structure of SARS-CoV-2 infected cells. Our measurements revealed infection remodeling caused by infection, including the emergence of new specialized areas where viral morphogenesis occurs at the cell membrane. Intercellular extensions for viral cell surfing have also been observed.

Advances in Vertebrate (Cyto)Genomics Shed New Light on Fish Compositional Genome Evolution.

Cytogenetic and compositional studies considered fish genomes rather poor in guanine-cytosine content (GC%) because of a putative "sharp increase in genic GC% during the evolution of higher vertebrates". However, the available genomic data have not been exploited to confirm this viewpoint. In contrast, further misunderstandings in GC%, mostly of fish genomes, originated from a misapprehension of the current flood of data.

Malformation of stapes in VACTERLS association: a histopathologic study and three-dimensional reconstruction.

Objective: To investigate the temporal bone with a malformed stapes in VACTERLS association.

Study Design: The study design was a case report, histopathology of the temporal bone, and three-dimensional reconstruction of the ossicles and cochlea.

Setting: The study was carried out in the Temporal Bone Bank at Charles University, Hradec Králové, on a case from Temporal Bone Foundation, Boston.
