Hematopoietic stem-cell transplantation refers to a procedure in which hematopoietic stem cells are infused to restore bone marrow function in cancer patients who receive bone-marrow-toxic doses of cytotoxic drugs with or without whole-body radiation therapy. Hematopoietic stem cells may be obtained from the transplant recipient (autologous HSCT) or from a donor (allogeneic HSCT). They can be h...

Endobronchial localizations of inflammatory myofibroblastic tumors are very unusual. We report the multimodal, bronchoscopic management 3 cases, offering durable local control in all cases (including 2 patients who were definitively cured). Although surgery is usually considered gold standard, therapeutic bronchoscopy should probably be as a frontline option for proximal lesions with limited ba...

Tacrolimus, a potent immunosuppressant medication, acts by inhibiting calcineurin, which eventually leads to inhibition of T-cell activation. The drug is commonly used to prevent graft rejection in solid organ transplant and graft-versus-host disease in hematopoietic stem cell transplant patients. Tacrolimus has a narrow therapeutic index with variable oral bioavailability and metabolism via cy...

the  non-classical mhc  class-i mainly involves in the  regulation of  innate  immune responses where hla-e  plays a significant role in the cell identification by natural killer cells. hla-e is a main regulatory ligand for natural killer cells and given the importance of these effector cells in hematopoietic stem cell transplantation, we investigated the effect of hla-e polymorphisms on post-h...

Hematopoietic stem-cell transplantation (HSCT) refers to a procedure in which hematopoietic stem cells are infused to restore bone marrow function in cancer patients who receive bone-marrowtoxic doses of cytotoxic drugs with or without whole-body radiation therapy. Hematopoietic stem cells may be obtained from the transplant recipient (autologous HSCT) or from a donor (allogeneic HSCT). They ca...

background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

BACKGROUND Although vitamin deficiencies are rare in the United States, acute reductions in concentrations of plasma retinol (vitamin A) or alpha-tocopherol (vitamin E) have been associated with impaired immune responses in some clinical settings. OBJECTIVE The objectives were to determine the plasma concentrations of retinol and alpha-tocopherol in patients undergoing dose-intensive therapy ...

Background: Although vitamin deficiencies are rare in the United States, acute reductions in concentrations of plasma retinol (vitamin A) or -tocopherol (vitamin E) have been associated with impaired immune responses in some clinical settings. Objective: The objectives were to determine the plasma concentrations of retinol and -tocopherol in patients undergoing doseintensive therapy and hematop...
