FGFR2 amplification and fusion identified by NGS align with FGFR2b overexpression

Inwoo Hwang, D Y Kim, Yuyeon Kim, Sion Lee et autres

FGFR2b is an emerging therapeutic target in HER2-negative advanced gastric cancer (AGC). However, diagnostic concordance between FGFR2b immunohistochemistry (IHC) and genomic assays has been inconsistent due to tumor heterogeneity. The clinical relevance of FGFR2 fusion also remains unclear given its low prevalence. …

Nasal Mucosal Necrosis in a Patient with Systemic Lupus Erythematosus and Antiphospholipid Syndrome: A Case Report and Literature Review

Dong Hoon Lee, Park Ks, Ahn Sj, Joo-Yeon Koo et autres

Background: The clinical presentation of nasal mucosal necrosis, an exceedingly rare manifestation of secondary antiphospholipid syndrome (APS) in patients with systemic lupus erythematosus, often mimics invasive fungal sinusitis (IFS), causing diagnostic challenges and potentially unnecessary surgical interventions. Here, we report a unique …

Lactiplantibacillus plantarum NCHBL-004 improves intestinal motility and modulates serotonergic gene expression in a loperamide-induced constipation model

Kim WI, Taesung Lee, C S Kim, Yong Wook Kim et autres

Slow-transit constipation (STC) is characterized by reduced colonic motility, impaired smooth muscle function, and altered mucosal signaling. Among these pathways, mucosal serotonin (5-HT), mainly produced by enterochromaffin cells, contributes to intestinal motility regulation. In a loperamide-induced constipation model in male C57BL/6 J …
