Are pyrazine analogues active components of wolf urine that induce avoidance and freezing behaviours in mice?
The current results suggest that wolf urinary volatiles can engender aversive and fear-related responses in mice. Pyrazine analogues were identified as the predominant active components among these volatiles to induce avoidance and freezing behaviours via stimulation of the murine AOB.
Pretreatment differential white blood cell count can be used to identify patients at increased risk of significant myelosuppression with FEC chemotherapy. Patients in the highest risk group have a risk of FN>20% and would qualify for primary prophylaxis with granulocyte colony-stimulating factor support under current guidelines.
