“Probiotics’ Clinical Effectiveness in Addressing Infectious Diseases: Potential Immunoregulatory Therapy in the Post-COVID-19 Era”

“Novel Strategies to Differentiate Graft-versus-Leukemia Effects from Graft-versus-Host Disease in Allogeneic Hematopoietic Cell Transplantation” * (* note: I have preserved the original capitalization from the abstract’s title, but if you strictly asked for a sentence that is not in title case, then “Novel strategies to differentiate graft-versus-leukemia effects from graft-versus-host disease in allogeneic hematopoietic cell transplantation” would be an appropriate response.)
