    “…Immunohistochemistry and real-time quantitative PCR were used to follow disease progression and demonstrated differences between the parent avian coronavirus and mutated avian coronavirus with a furin-S2′ site. Magnetic resonance imaging and biological dye to evaluate the blood-brain barrier permeability showed that avian coronavirus with a furin-S2′ site had increased permeability compared with that of the parent avian coronavirus. …”

    “…The emergence of secondary resistance is the main failure cause of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) as a targeted therapy for non-small cell lung cancer (NSCLC). EGFR mutations of NSCLC cells can markedly increase glutamine transporter (SLC1A5) expression, thereby increasing glutamine metabolism. …”

    “…METHODS: We used gene expression data from Gene Expression Omnibus to evaluate the expression landscape of 25 known CIFs in DLBCL patients and compared them with normal lymphoma tissues from two cohorts [GSE56315 (n = 88) and GSE12195 (n = 136)]. The mutational status of CIFs were also evaluated in The Cancer Genome Atlas database. …”

    “…The population consisted of 95 patients (48 males), median age at diagnosis 4.3 (range 0.8–17.2) and 12.6 (range 2.9–19.9) years at follow up, 27% familiar NF1, mostly nonsense or frameshift mutations. Neurological and/or visual symptoms were present in 64 (67.4%) patients. 63.6% of the tumors was in the optic pathway, 9.1% in the cerebellum. …”
