A variety of test methods were used to study the gradation, bioaccumulation, and toxicity of nicotine. Studies included determination of the octanol-water partition coefficient, conversion to CO2 in soil and activated sludge, and evaluation of the effects on microbiological and algal inhibition as well as plant germination and root elongation.

5502 Background: Epidermal growth factor receptor (EGFR) is expressed in 90-95% of head and neck squamous cell carcinoma (HNSCC). High EGFR gene copy number and activating mutations correlate with response and survival in lung cancer upon the treatment with EGFR tyrosine kinase inhibitors, but such findings have not been reported for HNSCC.

OBJECTIVE To investigate the presence of miRNA-144 in the saliva of patients with esophageal cancer and its value for early diagnosis of esophageal cancer. METHODS Saliva samples were collected form patients with esophageal cancer admitted in the Fourth Affiliated Hospital of Jinan University and the First Affiliated Hospital of Guangzhou Medical College(More)
OBJECTIVE To investigate the effect of CD59 gene inhibition mediated by RNA interference on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) GLC-P cells in vitro. METHODS Recombinant plasmids for RNA interference of CD59 gene were constructed and transfected into GLC-P cells via lipofectamine 2000. The stably transfected cells were(More)
