Background Icotinib has been widely used in patients with non-small cell lung cancer (NSCLC), and have significantly enhanced the overall survival rate of NSCLC patients. However, acquired drug resistance limits its clinical efficacy. Tumor cell-derived exosomes have been reported to participate in various biological processes, including tumor invasion, metastasis and drug resistance. Materials...
In this paper, a Q-band CMOS low noise amplifier (LNA) exploiting transformer positive-negative feedback and noise cancelling is presented. The proposed low noise amplifier consists of a positive transformer feedback to achieve noise-reduction and a negative transformer feedback to obtain high reverse isolation and stability. The noise cancellation technique is applied in this LNA to achieve...
