Work-up of total tumour specimens did not bring up any significant differences (Figure 5A, p= 0.9355) between untreated controls (percentage of Ki-67+ cells 77.4 +/− 7.3%), argon gas controls (78.3 +/− 6.7%,), plasma treatment for 10 seconds (76.6 +/− 7.5%), and plasma treatment for 20 seconds (76.0 +/− 3.1%). The gene discussed is MKI67; the disease is neoplasm.
