Optimal Treatment Approaches to Intestinal Behçet's Disease Complicated by Myelodysplastic Syndrome: The KASID and KSBD Multicenter Study.

Purpose: Studies on intestinal Behçet's disease (BD) complicated by myelodysplastic syndrome (MDS) are rare, and no established therapeutic guidelines exist. This study aimed to evaluate the clinical presentation and outcomes of patients with intestinal BD complicated by MDS (intestinal BD-MDS) and suggest a treatment strategy.

Materials And Methods: Data from patients with intestinal BD-MDS from four referral centers in Korea who were diagnosed between December 2000 and December 2022 were retrospectively analyzed.

Risk Factors for Surgery in Patients with Intestinal Behçet's Disease During Anti-Tumor Necrosis Factor-Alpha Therapy.

Purpose: Behçet's disease (BD) is a chronic inflammatory immune-mediated disease involving multiorgan systems. Gastrointestinal (GI) manifestations of BD include abdominal pain, vomiting, GI bleeding, fistula formation, obstruction, and perforation that might require surgery. Recently, anti-tumor necrosis factor-alpha (anti-TNF-α) therapy has been shown to have favorable outcomes in patients with intestinal BD who are refractory to conventional therapy.

Phytohormone abscisic acid control RNA-dependent RNA polymerase 6 gene expression and post-transcriptional gene silencing in rice cells.

RNA-dependent RNA polymerase 6 (RDR6) catalyses dsRNA synthesis for post-transcriptional gene silencing (PTGS)-associated amplification and the generation of endogeneous siRNAs involved in developmental determinations or stress responses. The functional importance of RDR6 in PTGS led us to examine its connection to the cellular regulatory network by analyzing the hormonal responses of RDR6 gene expression in a cultured cell system. Delivery of dsRNA, prepared in vitro, into cultured rice (Oryza sativa cv.
