The authors describe the results of purification of bone marrow and peripheral progenitor cells (PBPC) for clinical transplantations. Vepeside was used to purify in 1990-1995 a total of 41 bone marrows of adults and children. Of these 23 were transplanted. Maphosphamide was used bone marrow purging in two patients; transplantation was performed in one case. By a combination of Vepeside with methylprednisolone haematopoietic cells of 24 patients were purged, transplantations were performed in 10. Three-day cultivation of haematopoietic cells in the presence of Desferal was used for purging cells of 22 patients with neuroblastoma; transplantations were performed in 10 patients. The authors give the values of nucleated cells, haematopoietic colonies of CFU-GM and CD34 positive cells obtained after purification calculated per kg body weight of the patient and the percentage yields.

Background: Exosomes, which carry bioactive RNAs, proteins, lipids, and metabolites, have emerged as novel diagnostic markers and therapeutic agents for heart failure (HF). This study aims to elucidate the trends, key contributors, and research hotspots of exosomes in HF.
Methods: We collected publications related to exosomes in HF from the Web of Science Core Collection.

Non-small cell lung cancer (NSCLC) has emerged as one of the most prevalent malignancies worldwide. N6-methyladenosine (mA) methylation, a pervasive epigenetic modification in long noncoding RNAs (lncRNAs), plays a crucial role in NSCLC progression. Here, we report that mA modification and the expression of the lncRNA stem cell inhibitory RNA transcript (SCIRT) was significantly upregulated in NSCLC tissues and cells.

Background: Glioblastoma stem cells (GSCs) and their exosomes (exos) are involved in shaping the immune microenvironment, which is important for tumor invasion and recurrence. However, studies involving GSC-derived exosomal circular RNAs (GDE-circRNAs) in regulating tumor microenvironment (TME) remain unknown. Here, we comprehensively evaluated the significance of a novel immune-related GDE-circRNA in glioma microenvironment.
