Under-occlusion ('infraocclusion' as defined in the natural teeth) after implant restoration in the posterior area is commonly encountered in clinical practice; however, it has rarely been reported. Most importantly, the under-occlusion change mechanism remains unknown. The purpose of this case report was to analyze how the dentition of both arches changed in a patient, including teeth tilting, elongation and occlusal plane change with under-occlusion of the posterior implant restoration after long-term function.

Article Synopsis
  • COVID-19, caused by SARS-CoV-2, poses serious global health risks, including the potential for secondary liver injury related to metabolic enzyme changes.
  • This study explores how prior infection with SARS-CoV-2 affects alcohol-induced liver damage, using transgenic mice that express human ACE2.
  • Results showed that infected mice experienced worsened liver injury after alcohol consumption, with alterations in metabolic enzymes and increased levels of a toxic alcohol byproduct, indicating a complex interaction between COVID-19 and alcohol effects on the liver.

Discovery3 Team, Department of Research and Early Development, GC Biopharma, 93, Ihyeon-ro 30Beon-gil, Giheung-gu, Yongin-si, Gyeonggi-do, South Korea.

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare and life-threatening blood disorder characterized by the formation of blood clots in small blood vessels. It is caused by antibodies targeting the A disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13 (ADAMTS13), which plays a role in cleaving von Willebrand factor. Most patients with iTTP have autoantibodies against specific domains of the ADAMTS13 protein, particularly the cysteine-rich and spacer domains.
