Endovascular stent graft repair was developed to minimize the invasiveness of open surgery for thoracic and abdominal aortic diseases. This approach involves covering the diseased segment with a stented artificial graft. However, in thoracic endovascular aortic repair (TEVAR) for aortic arch diseases, special consideration is needed to preserve the aortic arch vessels.

The persistence of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the emergence of new mutant strains continue to present a substantial threat with potential for future pandemics. Safe, effective, and readily available COVID-19 therapeutics are urgently needed to prepare for future coronavirus pandemics. To help identify new antiviral agents, the present study focused on natural products in the extracts of Holy Basil, Ocimum tenuiflorum L.

An aneurysm sac enlargement caused by type II endoleak (T2EL) following endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms may cause serious complications such as rupture. Consequently, methods that preoperatively prevent or postoperatively treat T2EL have been employed. When significant aneurysm enlargement occurs due to persistent T2EL, embolization is first performed through several access points.

Article Synopsis
  • The COVID-19 pandemic has driven the search for new antiviral treatments targeting SARS-CoV-2, specifically the 3C-like protease (3CL).
  • Researchers developed a new class of covalent inhibitors using chlorofluoroacetamide (CFA) that effectively block the replication of the virus.
  • One specific compound demonstrated strong antiviral activity and favorable properties, indicating its potential as a lead candidate for COVID-19 treatment.
