Pro-Apoptosis Activity Of Pogostemon Cablin Benth. Against Nasopharyngeal Carcinoma Through The Bcl-2 Inhibition Signaling Pathway: A Computational Investigation, Aigia Syahraini, Essy Harnelly, Feri Eko Hermanto

Makara Journal of Science

Resistance to chemotherapy and radiotherapy frequently emerges in the later stage of nasopharyngeal carcinoma (NPC) tumorigenesis. The decreased response of NPC to radiotherapy and chemotherapy occurs owing to the inhibition of cancer cell apoptosis by the B-cell lymphoma-2 (BCL-2) protein. Thus, inhibiting BCL-2 protein may become a powerful approach to eliminate NPC through apoptosis regulation. Meanwhile, Pogostemon cablin is reported to exhibit anticancer properties, but there are limited studies on its use for NPC treatment. The objective of this study is to investigate the potential bioactive compounds in P. cablin as anti-apoptosis BCL-2 protein inhibitors using in-silico approach. Natural compounds …

There is a lack of data on the safety and efficacy of peritoneal drain (PD) and chest tube (CT) in the management of effusions in stem cell transplant recipients with veno-occlusive disease (VOD). In this retrospective pediatric study we compared the clinical outcomes and health resource utilization (HRU) in 32 patients with VOD who had a PD placed (PD+) post HCT with 27 patients who did not (PD-). Nine patients had a CT (7 PD+ and 2 PD-). PD+ patients were more likely than PD- patients to have received myeloablative conditioning (100% vs 85.2%; p=0.04) and have severe or very …

Background: Post-transplant cyclophosphamide (PTCy) has shown promising results with low rates of severe graft-versus-host-disease (GVHD), either alone or combined with conventional immunosuppression (CIS). However, studies comparing PTCy with CIS as a GVHD prophylaxis are scarce.

Objective: The study aimed to evaluate the rates of GVHD and survival outcomes in patients undergoing peripheral blood stem cell transplant (PBSCT) from HLA matched related donors (MRD) receiving PTCy based GVHD prophylaxis and to compare it with the outcomes of patients receiving methotrexate (MTX) and cyclosporine-A (CsA) as a GVHD prophylaxis.

Patients and Methods: Seventy-five patients with advanced hematologic malignancies who underwent MRD allogeneic …
