Combined Ganglioneuroma-Schwannoma of the Retroperitoneum: An Exceedingly Rare Hybrid Nerve Sheath-Ganglioneural Tumor.

Combined ganglioneuroma-schwannoma is an exceedingly rare tumor that has only been described in isolated case reports. We document a 64-year-old man with an incidentally discovered combined ganglioneuroma-schwannoma of the retroperitoneum that was intimately associated with sympathetic ganglia. We highlight the morphological and immunohistochemical findings of this rare tumor, and show evidence of its origin from sympathetic ganglia.

A comparative study between condensed polytetrafluoroethylene hernia mesh versus other composite meshes in Endo-laparoscopic ventral hernia repair.

Introduction: Laparoscopic ventral hernia mesh repair (LVHR) is gaining popularity possibly due to reduced complications, reduced hospital stay, early return to work and better cosmesis. In intra-peritoneal onlay method (IPOM) a dual layer composite mesh with an absorbable barrier on the visceral surface is used for minimising bowel adhesions. Three most popular prosthetic mesh scaffolds are polypropylene (PP), polyester and expanded polytetrafluoroethylene (ePTFE).

Feline coronavirus influences the biogenesis and composition of extracellular vesicles derived from CRFK cells.

Introduction: Coronavirus (CoV) has become a public health crisis that causes numerous illnesses in humans and certain animals. Studies have identified the small, lipid-bound structures called extracellular vesicles (EVs) as the mechanism through which viruses can enter host cells, spread, and evade the host's immune defenses. EVs are able to package and carry numerous viral compounds, including proteins, genetic substances, lipids, and receptor proteins.
