Landscape genetics and gene flow in the banana pathogenic fungus Mycosphaerella fijiensis [PDF]

, 2007
Among the different evolutionary forces driving population genetics, gene flow related to dispersal plays a major role in local adaptation processes. However very few studies on plant pathogenic fungi focussed on deciphering gene flow patterns at the ...

Utility of Computed Tomography Surveillance of Asymptomatic Infection in Children and Young Adults Before Allogeneic Hematopoietic Stem Cell Transplant

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
