Abstract Allogeneic hematopoietic stem cell transplant (HSCT) for adults with severe sickle disease (SCD) is potentially curative but not commonly utilized therapy due to complications such as graft failure (GF) and organ toxicity. Herein, we are reporting our long‐term outcome data of non‐myeloablative (NMA) HSCT in SCD emphasis on factors predicting event free survival (EFS). Adults undergoing NMA match‐related donor allogeneic from 2015 2021 at least 12 months follow‐up were included. A...

Abstract Benign prostatic hyperplasia (BPH) is a chronic, progressive disease characterized by mesenchymal cell-predominance and stromal glandular cell-hyperproliferation. Although, the precise cause of BPH unknown, it believed to be associated with hormonal changes in aging men. Despite androgens ageing are likely play role development BPH, pathophysiology remains uncertain.

Hepatits C virus (HCV) genotype 4 (GT4) shows low treatment response rates and discrepancies when compared to other genotypes. However, the reason underlying these remains unclear due limited number of studies on GT4. microRNA‑155 (miR‑155) is a noteworthy example discrepancy in GT4, as it was found be upregulated genotypes 1, 2 3 HCV infection, but downregulated GT4‑HCV‑infected peripheral blood mononuclear cells (PBMCs). The present study aimed investigate expression miR‑155 PBMCs, serum...
