Cellulose-mediated mechanical property tuning in small intestinal submucosal matrix to enhance stem cell osteogenic differentiation.

Natural extracellular matrices (ECM) provide a more accurate simulation of the cellular growth environment, making them excellent substrate materials for in vitro cell culture. The porcine small intestinal submucosa (SIS) is one of the most widely used natural ECM that display superior bioactivity. However, decellularization operations often result in fiber breakage and failure to recover mechanical strength in the SIS.

Long-term clinical outcome of a weekly 2-chlorodeoxyadenosine regimen in treatment-naïve patients with hairy cell leukemia.

Hairy cell leukemia (HCL) has a favorable clinical outcome with appropriate treatment; however, further research is needed on managing patients with relapsed or refractory disease and the risk of infection during prolonged periods. This study examined the long-term effects of 2-chlorodeoxyadenosine (2-CdA), particularly using a weekly infusion protocol, in treatment-naïve patients with HCL. This retrospective study evaluated the long-term follow-up data from 21 South Korean patients diagnosed with HCL.

Influence of Organ-Specific Extranodal Involvement on Survival Outcomes in Stage IV Diffuse Large B-Cell Lymphoma.

Background: The prognostic significance of extranodal sites in stage IV diffuse large B-cell lymphoma (DLBCL) remains uncertain, making it challenging to select appropriate treatment strategies for individual patients. In this study, we aimed to evaluate the influence of different extranodal sites on prognosis in young patients with stage IV DLBCL who achieved complete remission (CR) following initial chemo-immunotherapy and to explore the potential of autologous hematopoietic stem cell transplantation (ASCT) as a consolidation treatment for specific patient subgroups.

Methods: We retrospectively reviewed data from 119 patients with DLBCL aged < 60 years who achieved CR after chemo-immunotherapy between 2008 and 2020.

DL-ICE as a bridge to allogeneic transplantation in relapsed/refractory PTCL: survival outcomes and prognostic factors.

Introduction: Peripheral T-cell lymphomas (PTCLs) have poor outcomes in the relapsed/refractory (R/R) setting. In this study, we evaluated the efficacy of dexamethasone, L-asparaginase, ifosfamide, carboplatin, and etoposide (DL-ICE) chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with R/R PTCLs.

Methods: We retrospectively analyzed 80 adult patients with R/R PTCLs treated with DL-ICE chemotherapy between September 2009 and March 2023.

Two new species of Pseudocrangonyx (Amphipoda: Pseudocrangonyctidae) from the hyporheic zones in South Korea.

Pseudocrangonyx Akatsuka & Komai, 1922, is the most diverse group of subterranean amphipods in the groundwater communities of Far East Asia and is related to the biogeographic origin and evolution of subterranean amphipod fauna in the region. In this study, we describe two new subterranean species of pseudocrangonyctid amphipods, P. seomjinensis sp.
