Aggressive ovarian cancer may be linked to blood disorder
... will be to figure out whether thrombocytosis is a reaction to more aggressive ovarian cancer or whether the disorder itself exacerbates the disease, leading to poorer treatment outcomes for patients. What we find may also point to novel prevention approaches for our patients.

This finding confirmed the fMRI results revealing that the subjects were, indeed, perceiving patterns in the sequences.

Theoretically, this technique could be applied to any protein and would allow scientists to follow the dynamics of assembly and disassembly of intracellular structures containing the tagged protein.

He continued, "Future studies should focus on elucidating a possible mechanism for the negative effect of depression on the immune system and on wound healing."
