TL;DR: The BQ and XBB subvariants of SARS-CoV-2 Omicron are now rapidly expanding, possibly due to altered antibody evasion properties deriving from their additional spike mutations as discussed by the authors .

TL;DR: In this article , the authors evaluated the replicative ability and pathogenicity of authentic infectious BA.2 isolates in immunocompetent and human ACE2-expressing mice and hamsters.
Journal ArticleDOI
Diffuse duodenitis associated with ulcerative colitis.
TL;DR: Patients with pancolitis and DD do not necessarily have CD, but rather may have UC and, most importantly, that successful ERPT procedures may be performed in these patients.
Journal ArticleDOI
CD117 (KIT receptor) expression in Merkel cell carcinoma.
TL;DR: Twenty additional cases of MCC were evaluated and it was found that 21 of 22 tumors (95%) expressed CD117, and intensity of CD117 expression did not appear to correlate with aggressive behavior.
