Answer :
It is not possible to determine the conference where Dooley et al. (2018) presented their findings on heart transplant rejection using the provided references.
The study by Dooley et al. (2018) on the prediction of heart transplant rejection using histopathological whole-slide imaging doesn't appear to be referenced in the information you've provided. Without specific details of their publication or presentation, it's not possible to accurately state at which conference their findings were presented. Research in this field often includes studies on transplant rejection, immunology, and the search for biomarkers using various methods such as mass spectrometry and genetic analysis, as shown in the studies by Hutchinson et al. and the use of MALDI-TOF mass spectrometry in Proteomics 2005.
