Do reactions after whole blood donation predict syncope on return donation?
Donation experience strongly influences the likelihood of return donation and the risk of subsequent reactions, but a prior reaction after whole blood donation does not reliably predict recurrent syncope among returning donors.
The Arp2/3 protein complex is conserved from yeast to man, and in yeast the complex is required in vivo for the motility and integrity of cortical actin patches. We hypothesize that these patches may move by a Listeria-like mechanism driven by actin polymerization.
