Is level VII an important component of central neck dissection for papillary thyroid cancer?
CND incorporating both level VI and level VII can be undertaken safely through a cervical incision with no increased risk of permanent complications of hypoparathyroidism or recurrent laryngeal nerve injury. Failure to include level VII as part of CND will leave significant macrometastatic nodal disease behind in both therapeutic and prophylactic dissections. As level VII is in direct anatomic continuity with the pretracheal level VI nodes, it should be routinely included as part of every CND.
Overall, genes associated with the mitochondria were differentially expressed in resistant insects, and these differences may contribute to a reduction in overall metabolism and energy production and/or compensation in resistant insects. These data provide the first gene expression data on the response of phosphine-resistant and -susceptible insects to phosphine exposure, and demonstrate that RNA-Seq is a valuable tool to examine differences in insects that respond differentially to environmental stimuli.
