OBJECTIVES The role of genetic polymorphisms of tumor necrosis factor-alpha (TNF-α) for lung cancer development was evaluated. METHODS Genotypes of the TNF-α polymorphisms, -1210C>T, -487A>G, -417A>G, IVS1+123G>A, and IVS3+51A>G, were determined in 616 lung cancer cases and 616 lung cancer-free controls. RESULTS After adjusting for body mass index and smoking, each TNF-α genotype or haploty...

A flow injection method for the determination of readily assimilable nitrogen (r.a.n.), i.e. ammonium and aminated nitrogen, is reported. The difference in pH of the sample in the presence and absence of formaldehyde, which blocks the amino function, provides the value of r.a.n. by monitoring the changes in absorbance of bromothymol blue at 616 nm. The detection and quantification limits are 10...
