I think it's a bit to do with writing skills as well.
This sentence is what I'm referring to:
After the annoucement of that agreement in vivo results were announced from Southern Research.
You're saying UCSF was going to confirm, and that was announced, but then Southern Research actually announced results? And now KARD is validating WAHT previous study? Southern Research's or the initial KARD in vivo test.
I do not claim to be a proficient reader or writer.
